Description

The utility model relates to antenna technology and can be used for fastening pipe tubes of antenna-feeder devices (AFUs) on the belts of metal trellised supports during the construction (installation) of stationary communication facilities, including cellular communications.

AFUs on metal supports, as a rule, are installed on pipe stands, which, in turn, are mounted on the support belts — longitudinal structural elements that absorb the bulk of the load. The belts of existing metal lattice supports are made of corners or bent profiles. Pipe-resistant antenna-feeder devices (hereinafter referred to as pipe-mounted AFUs), as a rule, are made of pipes of circular cross-section, which are fastened in at least two places spaced along the length. Attachment points of AFU tube supports should ensure reliability of attachment and ease of installation on belts of supports of various sizes.

A device for attaching antenna elements is known [RF patent No. 2461924], containing two clamps made of elastic, their ends are rigidly fixed in studs, which are threaded ends placed in the corresponding holes of the clamping plate, the clamping plate, nuts for fixing and two basing strips made with prismatic cutouts, deployed in opposite directions, the base strips are connected to the clamping bar and to each other with bolts passing through.

The advantage of the device is its versatility, which allows you to fix the device on the belts of supports of various sizes, made of pipes. The disadvantage of this device is the difficulty of securing the device to a belt made of a metal corner or from a bent profile.

Known antenna mount [RF patent No. 28791], which is the closest technical solution, including a bracket with a hole for a mounting element, designed to secure the bracket on a support rod, characterized in that the bracket is made in the form of an angular element, the edges of which form a zone, designed to cover the antenna element, a longitudinally oriented groove is made on one face, the width of which is consistent with the width of the support rod, and on the other a hole is made for the fastening element. The advantage of the device is its small mass, which simplifies the process of its installation. The disadvantage of this device is the presence of holes in the supporting element, for example, the support belt, which reduces the bearing capacity of the latter.

The essential features of the claimed utility model are:

- The AFU pipe-mount attachment unit contains a bracket in the form of a corner element, the inner faces of which form a zone intended to cover the pipe-mount. Divergent angled internal faces of the brackets are capable of covering tube-mounted AFUs of various diametric sizes, which ensures the universality of the mount.

- Contains hooks designed to secure the brackets to the belt of the metal lattice support, each hook has a hook, body and threaded end. By hooking over the shelves of the metal lattice support belt and applying force to the threaded end, it is possible to secure the tube-mounted AFU. The length of the threaded parts of the hooks is chosen sufficient for the installation of tubules and staples on the belts of metal trellised supports made of corners or bent profiles of various sizes. The size of the hook and the length of the hook are selected depending on the maximum size of the belt of the metal lattice support in cross section, and the length of the threaded part - on the possibility of fixing on supports with belts of minimum dimensions.

- On the sides of the bracket, through grooves are made for the threaded ends of the hooks, as well as nuts and washers. By placing the threaded ends of the hooks in the through grooves of the bracket, it ensures its connection with the belt of the metal lattice support, and with the help of nuts and washers, they provide the transmission of the AFU pipe support fixing forces to the bracket. The length and location of the grooves is chosen sufficient to secure the tubes of various diameters.

- The bodies of the hooks form a zone designed to cover the tube-resistant AFU. The bodies of the hooks (their middle parts located between the hooks and the threaded ends) cover the tube of the AFU on the opposite side of the bracket, preventing the tube of the AFU from displacing in the plane perpendicular to its axis.

- The angle of the outer faces of the bracket is not less than the angle of the hooks, which is determined by the angle of the outer faces of the corner profile of the belt of the metal lattice support in cross section. The angle of the hooks is determined by the angle α of the outer edges of the belt in cross section, to which the hooks are pressed under the action of the fastening forces. When tightening the nuts, a gap is selected between the inner faces of the bracket, pipe-resistant AFU and the bodies of the hooks, which is accompanied by a displacement of the threaded ends of the hooks in the through grooves of the bracket. Such a displacement of the threaded ends of the hooks towards the top of the bracket is possible if the angle γ between the axis of the threaded part of the hook and the outer face of the bracket is at least 90 degrees. Otherwise, the displacement is difficult. Then the angle β at the top of the bracket must be at least the angle α at the top of the corner or bent element of the belt of the metal lattice support in cross section. At the same time, the transmission of fixing forces at an angle is carried out along the spherical surface of the end face of the nuts and / or washers. To prevent the nuts from being loosened, lock nuts (not shown) can be installed on the threaded ends of the hooks or anaerobic sealants can be used.

- The body of each hook is made with a deflection or with an increased transverse dimension. The deflection or increase in the body of each hook allows you to increase the distance And from the belt of the metal trellis support to the tube AFU., Necessary to place the mounting elements AFU. The sign provides fastening of the connected parts of various sizes in cross section, thereby achieving versatility.

- The dimensions of the hooks, the length and location of the through grooves on the faces of the brackets and the angle at which the inner faces of the brackets diverge, are selected depending on the different diametrical sizes of the AFU tubes. The sizes and arrangement of these elements are selected depending on the size range of the AFU tube supports, thereby achieving the universality of the mount.

- The body of each hook is made with a deflection of at least half the thickness of the body relative to the common plane of the hook and the threaded end of the hook. The specified deflection f allows you to place the hooks and threaded ends of two hooks in the same plane, while the deflection of one hook is located on the top and the other on the bottom. This eliminates the occurrence of forces that deploy the bracket when it is secured. If the hooks do not have the specified deflection f, the axis of the hooks cannot be located in the same plane, and to compensate for the turning forces, at least three hooks (two on one side and one between them on the other side) must be installed in each mounting point of the tube-mounted AFU.

- The body of each hook is made with a deflection located in the common plane of the hook and the threaded end of the hook. The deflection (bend) of the hook body is located on the side opposite to the hook hook, which allows to increase the distance A from the belt of the metal lattice support to the tube-mounted AFU.

- The body of each hook is made of increased transverse size due to the installation of a sleeve on it. The increased transverse body size of each hook also allows you to increase the distance A from the belt of the metal lattice support to the tube-mounted AFU.

These essential features of the utility model allow to obtain a technical result, which consists in increasing the versatility of the attachment point of the pipe supports of antenna-feeder devices on the belts of metal lattice supports. An accompanying technical result is a decrease in the complexity of manufacturing the mount.

The inventive mounting node does not violate the integrity of the belt support and pipe resistant, provides reliable fastening of connected parts of various sizes in cross section, thereby achieving its versatility. Reducing the complexity of manufacturing the mount is achieved by the presence in the design of only staples and hooks with fasteners.

The salient features of a utility model are:

- The bodies of the hooks form a zone designed to cover the tube-resistant antenna-feeder device.

- The angle of the outer faces of the bracket is not less than the angle of the hooks, which is determined by the angle of the outer faces of the corner profile of the belt of the metal lattice support in cross section.

- The dimensions of the hooks, the length and location of the through grooves on the edges of the brackets, and the angle at which the inner edges of the brackets diverge, are selected depending on the different diameters of the tubes of the antenna-feeder devices.

Distinctive features of the options for mounting the mount are:

- The body of each hook is made with a deflection of at least half the thickness of the body relative to the common plane of the hook and the threaded end of the hook.

- The body of each hook is made with a deflection located in the common plane of the hook and the threaded end of the hook.

- The body of each hook is made of increased transverse size due to the installation of a sleeve on it.

In FIG. Figure 1 shows a cross-section of an AFU pipe-mounting mount — an example where the angle of the outer edges of the bracket is greater than the angle of the hooks, which is determined by the angle of the outer edges of the angular profile of the belt of the metal lattice support in cross section.

In FIG. Figure 4 shows a general view of a bracket with two through grooves for installing two hooks with deflections. In FIG. 5 shows a general view of a hook with a deflection f. In FIG. 6 shows a general view of a hook with a deflection f relative to the common plane of the hook and the threaded end of the hook. In FIG. 7 is a cross-sectional view of an AFU pipe-mount attachment assembly — an example of using hooks with troughs depicted in FIG. 6 to install it on a metal lattice support belt of maximum size. In FIG. 8 is a cross-sectional view of an AFU pipe-mount attachment assembly — an example of using hooks with troughs depicted in FIG. 6 to install it on a small metal lattice support belt. In FIG. 9 is a cross-sectional view of an AFU pipe-mount attachment assembly — an example where each hook body 3b is made of an increased transverse dimension.

The AFU pipe-mounting attachment unit consists of a bracket 1 with through grooves 2, hooks 3, nuts 4 and washers 5. In FIG. 1-9 are additionally shown: a tube-resistant AFU 6, a belt of a metal trellised support 7, a hook body of an increased transverse size 8. The letters in FIG. 1-9 are marked: A is the distance from the belt of the metal trellised support to the tube-mounted AFU; f - hook deflection; α is the angle of the outer faces of the angular profile of the belt of the metal lattice support in cross section; β is the angle of the outer faces in cross section; γ is the angle between the axis of the threaded part of the hook and the outer face of the bracket in cross section. Each hook consists of a hook 3a, a body 3b and a threaded part 3c (Fig. 2).

The mount includes a bracket 1, made in the form of a corner element - a metal corner or a bent profile. The inner faces of the bracket 1 form a zone designed to cover the tube-resistant AFU 6 and force contact with it. On the faces of the bracket 6, through grooves 2 are made, in which the threaded ends 3c of the hooks 3 are located, nuts 4 and washers 5 are installed on the latter. The axis of the grooves is perpendicular to the longitudinal axis of the metal corner or bent profile. Hooks 3 are designed to fix the bracket 1 on the belt of a metal lattice support, each hook having a hook 3a, a body 3b and a threaded end 3b, the threaded end and the hook lying in the same plane, and the hook is made, as a rule, of a round metal bar. The bodies of the hooks 3b form a zone intended to cover the tube-shaped AFU 6. The nuts 4 and / or washers 5 are made with spherical ends, for example, according to GOST 14727-69 ∗, DIN 6319 C, respectively. The angle of the outer faces of the bracket 1 is made not less than the angle of the hooks, which is determined by the angle of the outer edges of the corner profile of the belt of the metal lattice support 7 in cross section, to facilitate the movement of the threaded ends of the hooks 3b along them during the fastening process. When using straight hooks (Fig. 3, 9), in which the axes of the elements 3a, 3b and 3c lie in the same plane, the bracket 1 contains at least three grooves 2 (Fig. 2). To compensate for the moment of rotation of the bracket under the action of the fastening forces, the through grooves should be staggered - two on one face and one on the other side, as shown in Fig. 2.

In the first embodiment, the mounting unit of the tube-mounted AFU on the belt of the metal lattice support, the body of each hook 3b is made with a deflection of at least half the thickness of the body relative to the common plane of the hook and the threaded end of the hook (Fig. 5). When using hooks with a deflection f, in which the axes of the elements 3a and 3c are in the same plane and the element 3b is out of the plane, the bracket 1 contains two grooves 2 (Fig. 4). In this case, the deflections f of the hooks are directed in different directions, and the elements 3a and 3b of both hooks lie in the same plane and compensation of the moment of rotation of the bracket under the action of the fixing forces is not required.

In the second embodiment, the mounting unit of the tube-mounted AFU on the belt of the metal trellised support, the body of each hook 3b is made with a deflection located in the common plane of the hook and the threaded end of the hook (Fig.6). When installing such hooks, the deflections of their bodies are located towards each other, which creates a support for the specified pipe stand AFU 6, moving it away from the belt of the metal lattice support (Fig. 7.8), which, as a result, allows you to connect parts of various sizes in the transverse section. When using hooks made in the second embodiment, the bracket 1 contains three grooves 2 (figure 2).

In the third embodiment, the mounting unit of the tube-mounted AFU on the belt of the metal trellised support, the body of each hook 3b is made of an increased transverse size 8 due to the installation of a sleeve on it. When installing these hooks, their bodies with increased transverse dimensions also create support for the tube-mounted AFU 6 of various transverse sizes, moving it away from the belt of the metal trellised support 7 (Fig. 9). When using straight hooks made according to the third embodiment, the bracket 1 contains three through grooves 2 (figure 2).

The mounting tube AFU 6 to the belt of the metal lattice supports 7 using the proposed mount is as follows. At least two points of attachment of the tube-mounted AFU to the belt of the metal lattice support are selected. At each mounting point, the threaded ends 3b of three hooks 3 are placed in the through grooves 2 of the bracket 1. The washers 5 are installed on the threaded ends 3b and nuts 4 are fastened. At each mounting point of the AFU pipe hooks 3a of hooks 3 are inserted behind the shelves of the metal lattice support belt 7. Tube The AFU 6 is brought into the zone formed by the inner faces of the brackets 1 and the bodies 3b of the hooks 3. The nuts 4 are tightened one by one. The bracket moves in the direction of the metal lattice support belt, the hooks 3 are pressed against the outer edges of the metal belt trellised support 7 and, in fact, the fixing tube-resistant AFU 6 between elements 1 and 3.

In the first embodiment, the mounting unit of the tube-mounted AFU on the belt of the metal trellised support is installed in two hooks 3 (Fig. 5) in the brackets 1 with two through slots (Fig. 4) at each mounting location. In the second and third embodiments of the assembly of the AFU mount, three hooks 3 (Fig. 3,6,9) are mounted on the belt of the metal trellised support in the brackets 1 with three through holes in each mount (Fig. 2). Further actions are similar to the actions described above.
