Description

The invention belongs to mine conveyor transport and is used in the construction of corner sections of scraper conveyors.

The corner section is designed to change the direction of movement of the traction body of the scraper conveyor in the horizontal plane.

There are known scraper conveyors for transporting coal, which contain an angular section, in the frame of which the change in the direction of movement of the traction body along the chute is carried out by rotating peripheral elements, which are made in the form of pulleys, which rotate in the horizontal plane relative to one common axis, which is fixed on the base of the section and fixed by a carrier plate fixed on the cover. At the same time, the pulleys in the area of the rake are separated by the bottom of the chute (11.

The disadvantages of this design are: - the difficulty of accessing the contour elements during their assembly - disassembly, - separate installation of the contour elements in the frame during assembly - disassembly; - use of the space of the bulk side of the conveyor during installation - dismantling of bypass elements.

The creation of the invention was based on the task of: - to simplify access to the contour elements during service maintenance of the corner section; - ensure joint installation - dismantling of bypass elements without using additional space of the bulk part of the conveyor.

As a result of the implementation of the task, a technical result can be obtained in the form of: - increased reliability; - reducing the service time of the corner section.

The solution to the given problem is achieved by the fact that in the corner section of a single-chain scraper conveyor containing a frame with a working chute curved radially relative to the axis of rotation of the bypass elements, which are coaxially placed in the frame with the possibility of independent rotation relative to each other, it is proposed to perform the bypass elements in the form rings that interact with the supporting elements placed inside them, the supporting elements should be made in the form of bodies of rotation and installed in the case, which is fixed on the frame.

The essential features of the invention listed above, different from the closest analogue, are also necessary

Z are sufficient in all cases covered by the scope of legal protection of the invention.

In addition, it is suggested: - support elements to be made in the form of rollers; - supporting elements should be made in the form of balls.

When determining the patentability of the claimed technical solution, it was found that its features clearly do not follow from the state of the art, which ensures that the proposed invention meets the "inventive level" criterion.

The invention 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.

The essence of the invention is presented in the drawings, where: - in fig. 1 shows the assembly-disassembly scheme of the case with peripheral elements; - in fig. 2 shows the body with rings and rollers in disassembled form; - in fig. Z shows a longitudinal section of the housing with rings and rollers assembled.

Brief description of the drawings: 1 - body; 1.1 - supporting part of the case (1); 2 - frame; 2.1 - gutter;

C - cover of the fastening element (1.1); 4 - body bolts; 4.1 - housing pins (1); 5 - cover bolts; b - rollers; 7 - rings; 7.1 - protrusion of the ring (7); 8 - spring discs; 9 - grooves of the side wall of the case (1); 9.1 - axle sockets (11); 10 - housing cover (1); 60 10.1 - ring grooves;

11 - roller axis (6); 12 - axle stopper (11); 13 - cover pins (10); 14 - stopper bolts (12); 15 - housing cover bolt (10).

The frame (2) of the corner section is made in the form of a welded metal structure, with a gutter (2.1) and a body (1) installed vertically in the frame (2), which is fixed against rotation on the frame (2) by pins (4.1) of the support part (1.1) and bolts (4).

The supporting part (1.1) of the housing (1) is closed with a cover (3) and fastened with bolts (5).

In the side wall of the case (2), there are grooves (9) with sockets (9.1), necessary for mounting axles (11), rollers (6).

Rollers (6) are supports for the rotation of two rings (7).

The upper ring (7) is installed as follows: after installing the rollers (b) in the grooves (9) of the housing (1), the ring (7) is installed, while the rollers (6) are pushed out coaxially with the sockets (9.1) from the side wall of the housing (1) ), the axes (11) are installed, after which the ring (7) is centered on the body (1).

Axes (11) are fixed using a stopper (12), which is installed in the housing (1) and fixed with bolts (14). To the rings (7) from above and below with the help of bolts and nuts, spring discs (8) are attached, which act as seals and prevent coal dust and slag from entering the housing (1). The case (1) is closed from above with a cover (10).

On the inner side of the cover (10), annular grooves (10.1) are made, which when connected to the protrusions (7.1) of the ring (7) form a tight connection of the "labyrinth" type, which does not allow the pin to get inside the body (1). The cover (10) is fixed on the frame (2) with pins (13) and fixed with bolts (15).

The lower part of the case (1) is assembled similarly to the upper part and consists of identical elements.

A distinctive feature of this design is the absence of a central axis of the upper and lower circumferential element. The frame has a block design, which allows you to pull out the bypass elements vertically together, without using additional space from the bulk side of the conveyor.
