Description

Pipeline installation device

Technical Field

The invention relates to the field of pipelines, in particular to a device for installing a socket type pipeline.

Background

A spigot-and-socket pipe is a pipe with a socket at one end and a spigot at the other end. As shown in fig. 1, the diameter of the female end is larger than the diameter of the pipe shaft of the pipeline, and the diameter of the female end is the same as the diameter of the pipe shaft. When installed, the spigot end of one conduit is inserted into the female end of another conduit as shown in figure 2. By connecting a plurality of pipelines in sequence, a pipeline can be laid. Different types of socket pipes are used to lay pipelines for various purposes, for example, a water supply pipeline for tap water is laid using a ductile iron pipe, or a sewage pipeline is laid using a concrete pipe.

As previously mentioned, during laying of the pipeline, it is necessary to butt the sockets and sockets of the two pipes, respectively. Because the laying process is usually carried out in an excavated ditch or underground pipe gallery, the space is narrow, large-scale equipment cannot be used, and the large-scale equipment can only be installed manually in the prior art.

The traditional method is to fix two ropes at the female end and the male end of the pipeline respectively, then connect a ratchet mechanism or a chain block with the two ropes respectively, and manually shake the ratchet mechanism by workers to pull the ropes or the chain of the block, thereby butting the two pipelines. This conventional method is time and labor consuming. Once the two pipelines are butted, the two pipelines cannot be separated, so that the two pipelines cannot be reinstalled even if the two pipelines are in a problem during installation, and only the pipeline installation transition structure can be cut.

Disclosure of Invention

The invention aims to provide a pipeline installation device which can be operated in a narrow space, reduces the operation load and can be used for dismounting a pipeline interface.

According to the invention, a pipe installation device for connecting the female end and the male end of two socket pipes comprises two fixing devices and at least two driving actuators. The two fixing devices are respectively detachably fixed at the female ends and the female ends of the two pipelines. Each driving execution mechanism is respectively detachably and fixedly connected with the two fixing devices.

Further, the fixing device is configured as a fastening device comprising a clamp and a locking clamp. Wherein, the shape after the clamp is locked is adapted to the appearance of the pipeline so as to fully clamp the pipeline. The clip is constructed to include at least two segments, adjacent segments being connected to each other, and further, adjacent segments being detachably or rotatably connected to each other. Furthermore, the clamp is equipped with the rubber pad that plays buffering, anti-scraping effect towards the one side of pipeline. Wherein, the fastening device can be a bolt and nut structure or a quick clamp, such as a tool clamp. In addition, a positioning cable is arranged between the two fixing devices, wherein the length of the positioning cable is adapted to the length of the driving actuating mechanism. Furthermore, at least two connecting rods are provided on the side of the fastening device facing away from the pipe, said connecting rods being configured to be arranged symmetrically with respect to the axis of the pipe.

Further, the driving execution mechanism is a hydraulic oil cylinder, a pneumatic cylinder or a screw driven by a motor. Furthermore, the driving executing mechanism can be also provided with a controller so as to control the operation of a hydraulic oil cylinder, a pneumatic cylinder or a motor. And two ends of the driving actuating mechanism are respectively provided with an open or closed ring.

Detailed Description

Embodiments of the present invention are described in detail below with reference to the accompanying drawings. Technical details which are known to a person skilled in the art are not described here.

As shown in fig. 3, the pipe installation apparatus according to the present invention includes two fixtures 1 detachably installed at a female end 10 and a male end 20 of a pipe, respectively. Each fastening device 1 comprises a clip 12 and a fastening device 14, respectively.

As shown in fig. 4, the clamp 12 is configured to lock in a shape that conforms to the external shape of the pipe. In a typical example, the cross-sectional profile of the conduit is substantially circular. Substantially circular as used herein means that the cross-sectional profile of the conduit employed is not strictly circular for different applications or due to dimensional tolerances or tolerances, i.e. the diameters are not exactly the same in all directions, but are slightly longer or shorter in some directions. Correspondingly, the shape of the band 12 is also substantially circular.

As also shown in FIG. 4, the clip 12 includes a plurality of segments 122 connected to one another. Adjacent segments may be configured to be releasably connected or non-releasably, rotatably connected, e.g., adjacent segments may be configured to be releasably latched or a hinged connection may be provided between the connected segments. Although 3 segments 122 are shown in fig. 4, one skilled in the art will appreciate that two segments may be used, or more segments, such as four or more segments, may be used.

The clamp band is typically made of metal, such as steel, or other materials, as long as the strength is sufficient for the application, such as high performance plastics.

On the inside of the clamp 12, i.e. the side facing the pipe, a rubber pad 126 is provided, which serves as a buffer, anti-slip and protecting the pipe surface coating. The rubber pad 126 may extend continuously or discontinuously on the inside of the band 12, i.e., may be distributed continuously on the band, or may be configured in a plurality of sections, uniformly or non-uniformly distributed. Still alternatively, the thickness of rubber pad 126 may be uniform or non-uniform. Those skilled in the art will appreciate that the arrangement of the rubber mats, as well as the thickness and distribution of the rubber mats, may be determined according to the particular application.

The fastening device 14 is configured to lock the ends of the band 12, and may be configured as a bolt and nut arrangement, or as a quick clamp, such as a tool clamp.

The fastening device shown in fig. 4 is a tooling clamp. Tooling calipers are commercially available and their manner of installation is well known in the art. For example, two bases 32 may be included, one base having a catch 34 and the other base having a link locking mechanism 36, each secured to an end of the clip 12. One side of a snap ring 38 is fastened to the hook for locking, and the other side is fixedly connected with the link locking mechanism. The above-described configuration is for illustration purposes only and is not intended to limit the present invention, and those skilled in the art may select a tool clamp of an appropriate configuration according to various application environments.

Fig. 6 shows another form of fastening device which is a bolt and nut arrangement and includes two bases 42 which are secured to respective ends of the band 12, either by rivets or by welding to the ends. The base is provided with a through hole through which a bolt 44 passes to connect the two ends and is then tightened using a nut 46 to lock the clamp 12 against the outer surface of the pipe.

Although two forms of fastening means are described herein in connection with fig. 4 and 6, one skilled in the art will appreciate that a variety of different fastening means may be selected, including but not limited to studs and other quick release locking mechanisms, so long as the clamp is locked. In addition, the fastening device can be adjusted to accommodate minor variations in pipe dimensions, for example, due to tolerances. For example, as shown in the tooling clamps of fig. 4, the snap ring can be adjusted to accommodate variations in pipe diameter due to tolerances, and for example, as shown in the bolt and nut configuration of fig. 6, bolts having threads of different lengths can be used to accommodate minor variations in pipe diameter.

Further, as shown in fig. 3 or 4, a connecting rod 124 is provided on the outside of the yoke 12. In the illustrated embodiment, two connecting rods 124 are provided and are symmetrically disposed about the conduit axis. In other embodiments, more tie rods may be provided, evenly distributed over the band, so that after the band is installed, the tie rods are symmetrical about the pipe axis. For example, three or four connecting rods may be provided, for example in the case of heavy pipes.

In the embodiment shown in fig. 3, two hydraulic rams 2 are used as the drive actuators. Both ends of each cylinder are respectively connected with the connecting rod 124. In the embodiment using a hydraulic ram, a ring 22 is provided at one end of the cylinder and at one end of the piston, respectively. The ring may be open or closed. Accordingly, the open loop 22 may be configured like a hook so as to hook over the aforementioned connecting rod 124, see fig. 5. A closed loop may be fitted over the connecting rod 124.

Further, the cross-sectional shape of the connecting rod 124 may be adapted to the shape of the ring, or may be changed as needed, and is not limited to the shape shown in the drawings. For example, including but not limited to, the rings being configured as oval rings, and the cross-sectional shape of the connecting rod may be configured as a corresponding oval or a suitably sized circle. The connecting rods and/or rings may also be constructed using square, rectangular or other suitable shapes. In addition, the connecting rod 124 may be configured in any suitable shape in the axial direction, for example, the dimensions may vary (see fig. 3 and 4), or the dimensions may be uniform.

Fig. 7 shows a different connection of the cylinder to the clamp in another illustrative embodiment. The clips 12 are each provided with two parallel plates 30, for example steel plates. Although the steel plate is described herein as being positioned symmetrically about the pipe, it will be understood by those skilled in the art that the position of the steel plate may be set as desired. Further, the spacing between the two steel plates may be set according to the particular application. The ring 22 at the end of the cylinder 2 is closed and arranged between two steel plates 30, and the steel plates 30 are respectively provided with corresponding holes. The ring 22 at the end of the cylinder corresponds to the hole in the steel plate and the pin 32 is inserted to effect the connection.

In another embodiment, the drive actuator may also be a pneumatic cylinder. Similarly, the aforementioned rings are provided at one end of the cylinder and at one end of the piston.

And, in another embodiment, the drive actuator may be a motor screw mechanism, the motor driving the screw to extend or retract the actuator. Similarly, the screw is provided with the aforementioned rings at each end.

In the above-described embodiments, the specific details of the hydraulic cylinder mechanism, the pneumatic cylinder mechanism, and the motor screw mechanism are not described. The person skilled in the art will be able to select a suitable existing institution for the solution of the invention on the basis of common general knowledge.

In addition, those skilled in the art will appreciate that control mechanisms, such as hydraulic, pneumatic, and click controls, may also be part of the drive actuators described above, or may be separate devices.

In the above description details of the solution according to the invention have been set forth, however, it will be clear to a person skilled in the art that the invention is not limited to the details set forth in the examples described above, but that it may vary within the scope defined by the claims.
