Description

Technical field

The technical solution relates to equipment for the mining industry, namely, to sections of grooves of scraper conveyors, and can be used for underground mining of rock mass.

State of the art

The prior art section of the chute for underground downhole and drift conveyors, including a frame structure having side walls, which include the lower and upper shelves, as well as connecting them protruding intermediate shelf, provided with a bend, on which from the inside is made at least , one step for supporting and welding at least one intermediate sheet. The lower flange of the rolled profile ends with an approximately L-shaped thickening forming a support [1].

The disadvantage of this design is that the protrusion of the L-shaped thickening is made as a support and is not intended for welding other parts to it.

As the closest analogue from the prior art, profiles shaped for the sides of the pans of scraper conveyors according to TU U 27.1-26524137-1355: 2007, made Σ-shaped, have an end wall formed by the outer and inner surfaces, which in the middle part are made with V -shaped bend, which from the side of the inner surface in the narrowed part ends with a protrusion, and the upper and lower shelves adjacent to the end wall, made with a slope in the direction from the axis of symmetry of the profile, and have outer and inner surfaces awns. The outer surfaces of the upper and lower shelves are parallel to each other. As an embodiment of the profile profile for the sidewalls of the pans of scraper conveyors according to TU U 27.1-26524137-1355: 2007, the protrusion in the middle part of the V-shaped bend is equipped with a step [2].

The disadvantage of this profile is that it is made for the assembly technology of scraper conveyor pans, when the Σ-shaped profile is installed on the sheet with the outer surface of the lower shelf and welded from the side of the ends of the shelf. This technology of sheet welding does not provide sufficient reliability of the welded assembly. In addition, a large integral sheet is needed so that it is simultaneously the bottom of the lower branch of the gutter section of the scraper conveyor and a support for attachments outside the gutter.

A task

To create a technological sidewall profile, which, when welding with other parts of the gutter section of the scraper conveyor, will ensure sufficient reliability of the welded joints.

As a result of solving the task, a technical result will be obtained, which is to provide improved quality of welds by introducing special structural elements into the sidewall profile.

Consumer properties: an increase in the overhaul cycle of using a scraper conveyor and an improved technology for assembling a section of the groove of the scraper conveyor.

Utility Model Disclosure

The solution of this problem is achieved by the fact that in the sidewall profile of the gutter section of the scraper conveyor, which has an end wall (1) formed by the outer (1a) and inner (1b) surfaces, made in the middle part with a V-shaped bend ( 2), which on the side of the inner surface (1b) ends with a protrusion (2a), and the upper (3) and lower (4) shelves adjacent to the edges of the end wall (1) from the side of its inner (1b) surface, which have outer (3a) and 4a) and internal (3b and 4b) surfaces, while the outer the surface (4a) of the lower flange (4) is provided with a protrusion (5), in accordance with a utility model it is proposed that the protrusion (5) be made with two side ribs (5a and 5b) with an inclination in the form of a chamfer for welding, while the line that forms one of the side ribs (5a) has a point of intersection (6) with the outer (1a) surface of the end wall (1), and the line that forms the second side rib (5b) has a point of intersection (7) with the outer (4a) surface the lower shelf (4), while the height (h) of the protrusion (5) from the outer (4a) surface of the lower shelf (4) of the profile is selected from the dependence:

0.5k≤h≤1.5k,

where k is the height of the protrusion (2A) of the V-shaped bend (2).

In addition, it is proposed:

- carry out the inner (3b and 4b) surfaces of the upper (3) and lower (4) flanges with a slope in the direction from the axis of symmetry (X) of the profile;

- the outer surfaces (3a and 4a) of the upper (3) and lower (4) shelves should be parallel to the axis of symmetry (X) of the profile;

- the protrusion (2A) of the V-shaped bend (2) to perform in the form of a rectangle;

- provide the protrusion (2a) of the V-shaped bend (2) with at least one step (2b) with the possibility of its interface with a flat surface;

- to provide the ledge (2a) of the V-shaped bend (2) in the form of a rectangle with chamfers (2c) for welding.

The causal relationship between the newly introduced essential features and the technical result is explained as follows. Equipping the outer surface (4a) of the lower flange (4) of the profile with a protrusion (5) with two side ribs (5a and 5b) with an inclination in the form of a chamfer for welding allows you to provide the necessary parameters for the weld pool for the electrode when welding with the bottom sheet of the lower branch of the gutter section scraper conveyor and support sheet for attachments outside the gutter. The intersection of the line forming one lateral rib (5b) of the protrusion (5) with the outer (4a) surface of the lower flange (4) of the profile leaves a straight section of the outer surface (4a) of the lower flange (4) free. This allows you to orient the sheet of the bottom of the lower branch of the trough section of the scraper conveyor that is welded to the sidewall profile and provide the necessary parameters for the weld pool for the electrode during welding. The intersection of the line forming the second side rib (5a) with the outer (1a) surface of the end wall (1) allows, by changing the angle of inclination of the support sheet for attachments outside the gutter, to provide the necessary size and parameters of the weld pool for the electrode during welding. The height (h) of the protrusion (5) is chosen sufficient to provide the necessary depth of the weld pool for the electrode during welding from the dependence: 0.5k≤h≤1.5k, where k is the height of the protrusion (2a) of the V-shaped bend (2a).

As a result, these features provide a technical result: improving the quality of the weld in comparison with the closest analogue and give the technical solution consumer properties: an increase in the overhaul cycle of using a scraper conveyor due to the provision of better welded joints and an improved assembly technology. For the claimed design of the profile does not need a solid sheet for the lower bottom, as in the prototype, you can use separate pieces for the bottom of the lower branch of the gutter section of the scraper conveyor and the rest of the sheet, for support under the attachment outside the gutter.

Industrial applicability

The implementation of the technical solution is shown in the examples (Fig. 1-3), which are not exclusive, but clearly demonstrate the possibility of achieving the claimed technical result.

The sidewall profile of the gutter section of the scraper conveyor is an end wall (1) formed by the outer (1a) and inner (1b) surfaces, made in the middle part with a V-shaped bend (2). From the side of the inner surface (1b) of the end wall (1), the bend (2) ends with a protrusion (2a). As an embodiment, the protrusion (2a) of the V-shaped bend (2) is made rectangular (Fig. 1), but to improve the reliability of welding the sidewall profile with the transport bottom (not shown in the figures) in FIG. 2 and FIG. Figure 3 shows embodiments of the protrusion (2a) of the V-shaped bend (2) with a step (2b) and with chamfers (2c) for welding.

On the edges of the end wall (1) from the side of its inner (1b) surface, the upper (3) and lower (4) shelves adjoin which have outer (3a and 4a) and inner (3b and 4b) surfaces. As an embodiment, the inner surfaces (3b and 4b) of the upper (3) and lower (4) flanges are made with a slope in the direction from the axis of symmetry (X) of the profile (Fig. 1), although other designs are possible, for example, the execution of internal surfaces (3b and 4b) parallel to the axis of symmetry (X) of the profile, inclined to the latter (not shown in the figures), etc. The outer surfaces (3a and 4a) of the upper (3) and lower (4) shelves in the example are parallel to the axis of symmetry (X ) profile (Fig. 1), although other designs are possible, for example, the execution of the outer surfaces (3a and 4a) with a slope ohm from or to the axis of symmetry (X) of the profile (not shown in the figures).

The outer surface (4a) of the lower flange (4) is performed with a protrusion (5), which in accordance with the claimed technical solution has two side ribs (5a and 5b), each of which is made with an inclination in the form of a chamfer for welding. The line forming one of the side ribs (5a) of the protrusion (5) has a point of intersection (6) with the outer (1a) surface of the end wall (1), and the line forming the second side edge (5b) of the protrusion (5) has an intersection point (7) with the outer (4a) surface of the lower shelf (4).

The choice of the height (h) of the protrusion (5) of the outer surface (4a) of the lower flange (4) of the profile depending on the height (k) of the protrusion (2a) of the V-shaped bend (2) provides a relationship between the thickness of the sheet of the transport bottom (not shown in the figures) , which transported the rock mass and the thickness of the sheet of the lower bottom (not shown in the figures) idling conveyor scrapers. This is important because wear of these sheets and their replacement should be carried out during repair at the same time. The height (h) of the protrusion (5) is selected sufficient to provide the necessary depth of the weld pool for the electrode when welding with the bottom bottom of the idle of the scrapers from the dependence:

0.5k≤h≤1.5k,

where k is the height of the protrusion (2A) of the V-shaped bend (2a), and also relates the heights of both protrusions (2a) and (5) from the point of view of the operating time of both bottoms (not shown in the figures), which are welded to the protrusions (2a) and (5). The height (h) of the protrusion (5) in the selected range from 0.5k to 1.5k is the most optimal for the profiles of the sidewalls of the sections of the grooves of the scraper conveyors of different heights.

For the specialist from the previous description, numerous modifications follow that fall within the scope of protection of the attached claims of the utility model.
