Description

Field of technology

The invention belongs to the equipment for the mining industry, in particular, it can be used in the connection nodes of the sections of the scraper conveyor chute.

Technical level

From the state of the art, a device is known for connecting scrapers of a scraper conveyor, which contains blocks fixed in depressions on the outer side of the sides of the scrapers, in the sockets of which there is a connecting rod made with heads and a shank installed on one of the heads of the connecting rod. and a support element for fixing against axial movement of the connecting rod and the retainer, which is made in the form of a c-shaped bracket, which covers the shank of the connecting rod and is fixed on it with the help of a pin, and the support element is made in the form of a rib with a recess for placement shank of the connecting rod |11.

The disadvantages of this design are: 1) complexity in manufacturing; 2) inconvenience of installation/disassembly, because additional space is needed along the axis of the rack.

From the state of the art, a device for connecting scrapers of a scraper conveyor is known, taken as the closest analogue, containing a connecting roller with heads that interact with a locking element, placed in the profile recesses of the side walls of the scraper sections, symmetrically relative to the connector line, while profile recesses are made with annular channels and centering conical surfaces at the ends for the heads of the roller, which has a cylindrical support section in the middle, conical heads at the ends and necks, surrounded by closing elements made in the form of spring-loaded rings with a hole, placed in the annular grooves of the profile depressions. Ring channels are made with stops (21.

The disadvantages of this design are: 1) the complexity and high cost of manufacturing its parts, for example elastic rings or conical surfaces of the heads of the connecting roller, which requires special materials and their processing technology; 2) the difficulty of installation, in particular in the case of the need for replacement, since the installation of connecting rollers with cone-shaped heads that interact with the locking element is possible only when the grates are disassembled, which is very problematic when the conveyor is assembled, because this, in turn, requires opening the scraper chain, which requires additional costs.

The task of the invention

To create a simple design of the connection unit of the sections of the scraper conveyor chute, which will ensure its quick and convenient assembly/disassembly.

As a result of solving the given problem, a technical result can be obtained, which consists in simplifying the design of the connection node of the scraper conveyor chute sections, while ensuring a high-quality connection. Consumer properties: reduction of costs for manufacturing and assembly/disassembly of the connection unit of the chute sections of the scraper conveyor.

Disclosure of the invention

The solution to the problem is achieved by the fact that in the already known node of the connection of the sections of the scraper conveyor chute, which includes a connecting element made with heads, one of which is equipped with a shank, connected by a support section, and placed in a channel opened by a through groove, which is formed by longitudinal coaxial holes made in the protrusions on the side walls of two adjacent sections of the chute, the retainer, which is made in the form of a bracket fixed on the shank of the head of the connecting element with the possibility of contact of the retainer in the longitudinal direction with the support element, which is installed on the side wall of one from the sections of the chute, according to the invention, it is proposed: - on the support area of the connecting element, parallel to its longitudinal axis, make at least one flat cut, on which, connected to at least one of the heads, perpendicular to the longitudinal axis of the connecting element, make a cut protruding above the surface a step that will interact with its outer side floors with the inner side surfaces of the through groove with the possibility of fixation in the last connecting element, while the height of the cross section of the support section in a flat section should be smaller than the width of the through groove; - the support area should be made cylindrical with an additional flat section, which is parallel to the first flat section; - parallel to the flat cuts on the support section, equidistant from the longitudinal axis, make flat cuts on the cylindrical heads of the connecting element.

The causal relationship between the newly introduced essential features and the declared technical result is explained as follows. Making a flat section parallel to its longitudinal axis on the support area of the connecting element with a step protruding above it perpendicular to the longitudinal axis, which is adjacent to one of the heads of the connecting element, allows you to simplify the design of the connecting element and, accordingly, the surfaces of the connected with it details of the node. The need to manufacture accurate conical or inclined surfaces in connected pairs of parts is eliminated. At the same time, a flat section, and even two, as in the example, with a cross-sectional height smaller than the width of the through groove, allows the service personnel to insert the connecting element in one movement into the coaxial ring channels on the side walls of two adjacent sections of the chute and turn it to 907, which simplifies the assembly/disassembly of the junction of the gutter sections.

The step, protruding above the flat section, forms the outer side surfaces, which are used to fix the connecting element in the inner side surfaces of the through groove, which is present in the protrusions of two adjacent sections of the conveyor chute, excluding the possibility of rotation of the connecting element. At the same time, in the prototype, the connecting element has the ability to rotate in the channels under the action of shock loads, which requires the manufacture of the element itself and the parts connected to it from wear-resistant materials.

Attaching a step to one of the heads of the connecting element allows to reduce the distance required to move the connecting element along the chute during assembly/disassembly. This distance is determined by the width of the step, which is chosen depending on the operating conditions of the conveyor, accordingly, the supporting part of the connecting element is extended only by this amount. Thus, the set of features ensures the achievement of the technical result: simplification of the node design.

The technical solution is explained by an example, the implementation of which is not the only possible one, but clearly demonstrates the possibility of achieving a technical result with the proposed new set of essential features.

Industrial suitability

Implementation of the proposed technical solution is carried out in the following way.

The connection unit of two adjacent sections (1) and (3) of the scraper conveyor chute includes a connecting element (2) installed in protrusions (1.2) and (3.2) on the side walls of two adjacent sections (1) and (3), the fastener (4), made in the form of a bracket, fixed on the shank (2.2.1) of the head (2.2) of the connecting element (2) and the supporting element (5), which is installed on the side wall of one of the sections (3) of the gutter (fig. .1, 2). The connecting element (2) (Fig. 3), which for ease of manufacture is made in the form of a body of rotation, has heads (2.2) and (2.3), which are coaxially (U) connected by a support section (2.1). One of the heads (2.2) is equipped with a shank (2.2.1) with a through hole (2.2.4). Along the entire length of the support section (2.1) of the connecting element (2), parallel to its longitudinal axis (U) and parallel to each other, two flat sections (2.4) and (2.6) are made, in the example, equidistant from the longitudinal axis (U), although for the implementation of the invention, it is enough to make one flat section. On one flat section (2.4), joining one of the heads (2.2), a step (2.5) protruding above the surface of the flat section (2.4) is made, which has two outer side surfaces (2.5.1) and (2.5.2). Each head (2.2) and (2.3) is provided with sections (2.2.3) and (2.3.1) parallel to each other and parallel to flat sections (2.4) and (2.6) of the support section (2.1), which are designed so that the heads do not advocated the overall dimensions of sections (1) and (3) of the gutter after installation of the connecting element (2). On one of the heads (2.2) or (2.3) perpendicular to the flat section (2.2.3) or (2.3.1), a through-through technological hole (2.2.2) is made (Fig. 3).

On the side walls of two adjacent sections (1) and (3) of the chute, protrusions (1.2) and (3.2) are made, which can be, for example, welded or cast together with the sidewall, etc. Protrusions (1.2) and (3.2) have holes (1.1) and (3.1), each of which is opened by a through groove of the same width (I). During

From the assembly of sections (1) and (3) of the chute, they are installed in such a way that the holes (1.1) and (3.1) form a continuous channel with a common axis (Х), and the through grooves in them are a common through groove (7) with a width of (І ), which is greater than the height (n) of the cross-section of the support section (2.1) with a flat section of the connecting element (2) by the amount necessary and sufficient for passage through the through groove (7) of the support section (2.1) (Fig. 4, 5 ).

The retainer (4), made in the form of a bracket, is installed on the shank (2.2.1), after which it is fixed on it with a stopper (6) through a through hole (2.2.4). The support element (5) in the form of a flat sheet is rigidly installed on the side wall of one of the sections (3) of the chute to provide support for the latch (4).

The assembly of the junction of sections (1) and (3) of the scraper conveyor chute is carried out in the following sequence. Two adjacent sections (1) and (3) of the scraper conveyor chute connect each other with protrusions (1.2) and (3.2) to form a common channel (X) with a common through-groove (7) width (I). Then the connecting element (2) is installed in the holes (1.1) and (3.14), having previously turned its head (2.2) with the shank (2.2.1) towards the support element (5). Then the connecting element (2) is turned so that the surfaces of the two sections (2.4) and (2.6) are parallel to the inner side surfaces (I) and (I 2) of the through groove (7).

Since the height of the cross-section (n) of the support section (2.1) with a flat section of the connecting element (2) is less than the width (I) of the through groove (7), the connecting element (2) passes through the groove (7) and enters into channel (X). Then the connecting element (2) is turned by 90", thereby securing it from falling out through the through groove (7). For the convenience of turning the connecting element (2) by 90", a technological hole (2.2.2) is used, in which the rod is inserted and turned to the desired position around the axis (U). During these operations, the step (2.5), which protrudes above the flat section (2.4), is outside the channel, and only after turning the connecting element (2) by 90" with a movement along the axis of the channel (X), the connecting element (2) are arranged so that the step (2.5) with its outer side surfaces (2.5.1) and (2.5.2) contacts the inner side surfaces (I 1) and (I2) of the through groove (7), fixing against possible rotation around its axis ( Y) and, accordingly, the connecting element (2) falls out. After installing the connecting element (2) in the channel (X) on the shank (2.2.1), a fastener (4) made in the form of a bracket is put on, connecting the longitudinal axes holes in the retainer (4) and on the shank (2.2.1), in which the stopper (6) is then inserted. The retainer (4) interacts with the support element (5) in the longitudinal direction, thus preventing the longitudinal displacement of the connecting element (2) and the output of the outer side surfaces (2.5.1) and (2.5.2) of the riser (2.5) from the interaction with the inner side surfaces (I) and (I 2) through groove (7), and, accordingly, from falling out.

The junction of sections (1) and (3) of the scraper conveyor chute is very easy and quick to assemble and ensures reliable fixation of the chute sections. Disassembly of the junction of sections (1) and (3) of the scraper conveyor chute is carried out in the reverse order.
