Description

The useful model belongs to the conveyor transport and can be used in the inspection sections of the scraper conveyor chute.

A well-known section of the inspection chute of a mine scraper conveyor is chosen as an analogue, which contains the bottom and backfill sidewalls, rigidly connected to each other by the lower and upper bottoms.

The upper bottom is made with an inspection hole, the edges of which have shoulders. The slaughter side is made with a through hole. The removable cover is installed on the shoulder and in the through hole of the slaughter sidewall, the height of which is greater than the thickness of the removable cover by the amount of the gap 5, which is sufficient for installing the removable cover through the through hole of the slaughter sidewall. The inspection hole and the removable cover are trapezoidal in shape. Shifting the bulkhead edge of the removable cover up is impossible, due to its interaction with the bulkhead sidewall and placement of its part in the through hole of the bulkhead sidewall.

A quick-release latch is installed on the outside of the slaughter sidewall, which fixes the removable cover.

The retainer is made in the form of a rod located in a vertical hole on the outer side of the slaughter sidewall. The rod is made with a turnkey head and a radial protrusion (travel limiter), which can contact the stop on the outside of the hammer sidewall.

Holes are made in the cover for interaction with the assembly tool.

Installation of the removable cover is carried out through the through hole of the slaughter side thanks to the gap 5, by the size of which the through hole exceeds the thickness of the cover. The cover is installed by moving it through the hole in the slaughter sidewall along the shoulders until it stops in the backfill sidewall and connecting it to the through hole made in the backfill sidewall.

The removable cover is fixed from shifting with a rod installed in a vertical hole on the outside of the slaughter sidewall. To prevent the rod from falling out, the head is turned with a key so that its radial projection begins to interact with the stop of the hammer side.

Dismantling of the removable cover is performed in the reverse sequence by removing the latch. To extend the removable cover, a dismantling tool is used, inserting it into the holes at the end of the cover from the outside of the slaughter sidewall. (11

The disadvantages of this design include:

There is a high probability of the lid being pinched by deforming forces on the shelf of the slaughterhouse

From the side in the area of the through hole, in which the cover should move freely. The side of the chute of the scraper conveyor, in which a long through groove is made, is a weak point and under load it will be precisely the part of the chute with the groove that will deform;

For installation/disassembly of the cover, the service personnel need a large distance from the side of the chute, which is equal to the length of the cover, that is, almost the width of the chute itself, it is necessary to specially clear the area to pull out the cover, which is associated with the risk of rock collapse and injury to the service personnel.

The purpose of the useful model is to increase the rigidity of the section structure at the place of installation of the cover 5, to ensure the maximum safety of the service maintenance of the section.

The technical result of the useful model is the creation of a simple and convenient design of the inspection chute section of the mine scraper conveyor, both in manufacturing and in maintenance.

Consumer properties: improving the state of safety equipment and reducing the number of repairs.

The task is solved by the fact that in the section of the inspection chute of the scraper conveyor, which contains the side walls (2) and (3), rigidly connected to each other by the bottom (1), in which a through inspection hole (4) is made, is installed on the shoulder (4.1 ) in the inspection hole (4) of the cover (6), with the possibility of its interaction with at least one removable latch (7) installed in at least one side part (2), in which at least one through hole (2.1) is made at the level of the inspection hole (4) ), while the latch (7) is fixed on the outside of the sidewall (2), according to the useful model, the through hole (2.1) is made with the possibility of limiting the horizontal movement of the cover (b) by the inner surface of the sidewall (2), the end (7.2) of the removable latch (7) ) is brought out through the through hole (2.1) inside the section with the possibility of limiting the upward movement of the cover (b).

The essential features of a utility model listed above, different from the closest analogue, are necessary and sufficient in all cases covered by the scope of legal protection of a utility model.

According to the useful model, in the surface of the cover (b), which interacts with the surface of the shoulder strap (4.1), make an open groove (6.3) combined with an open groove (4.2), which is made in the side surface of the opening (4) above the shoulder strap (4.1).

According to the useful model, the latch (7) should be made in the form of a horizontally installed rod.

According to the useful model, the end (7.2) of the retainer (7) should be made in the form of a step, the surface of which interacts with the bottom of the open groove (6.1), which is made on the upper surface of the edge of the cover (6) and is combined with the hole (2.1).

A useful model 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 20 essential features.

Industrial suitability

A useful model is presented on the example of a section of an inspection chute of a scraper conveyor, the side walls (2) and (3) of which are curved and rigidly connected by two bottoms (10) and (1) (Fig. 2 and

Fig. b).

An open groove (3.1) is made horizontally on the inner surface of the sidewall (3) (Fig. 2).

The bottom (1) is presented with an inspection hole (4) (Fig. 3 and Fig. 4) of a rectangular shape, in which shoulder straps (4.1) are oppositely made. Open grooves (4.2) are made above the shoulders (4.1) in the side surface of the opening (4) (Fig. 1 and Fig. 6).

In the bend of the sidewall (2), a vertical bar (9) is rigidly fixed, in which a through hole (9.1) is made, combined with a through hole (2.1) of the sidewall (2) (Fig. 2).

The sidewall (2) is rigidly connected to the blade (5), in which holes (5.1) are made, aligned with holes (9.1) (Fig. 2 and Fig. 6).

The blade (5) is connected to the sidewall (2) by a horizontal shelf (5.2), in which vertical holes (5.3) are made under the through holes (2.1) (Fig. 2).

The cover (6) is rectangular in shape. At one end of the cover (6) in the end part, a step (6.2) is made (Fig. 2), and at the other opposite end, two open grooves (6.1) are made on the upper surface of the cover (b) (Fig. 2 and Fig. 6), in addition, open grooves (6.3) are made on the other two opposite sides of the cover (6) in the ends under the upper surface (Fig. 3 and Fig. 4).

The retainer (7) is presented in the form of a rod (hereinafter the rod) with a step (7.2) at one end and an annular groove (7.1) for fitting the elastic bracket (8) at the other end (Fig. 5).

In the closed position, the cover (b) is installed in the inspection hole (4) on the shoulder strap (4.1). because the step (6.2) is connected to the open groove (3.1) so that the horizontal surface of the groove (3.1)

limits upward movement of steps (6.2). On the side of the side panel (2), the cover (b) is fixed by two vertically installed identical rods (7), each of which is installed, respectively, through the hole (5.1) into the through hole (9.1) and through hole (2.1) of the side panel (2), so that the step (7.2) of each rod (7) is installed above the bottom of the open groove (6.1) and limits the upward movement of the cover (6).

In order to exclude the arbitrary exit of the stage (7.2) from the open groove (6.1), as a result of the vibration that occurs in the operating mode of the conveyor, the rod (7) is held by a vertically installed elastic clamp (8), which is coupled with the annular groove (7.1) and placed in gaps (5.3).

The grooves (6.3) of the cover are combined with the grooves (4.2).

To dismantle the cover (b), the worker first removes the clamp (8) from the ring groove (7.1) of each rod (7) and through the hole (5.1) removes the rod (7) from the holes (9.1) and (2.1) until the open groove is completely released ( 6.1) from step (7.2). The worker inserts the assembly tool into the open groove (4.2) until it connects with the surface of the open groove (6.3), then the end of the cover (b) with the open grooves (6.1) is raised by the assembly tool to an angle sufficient for it to be grasped by hands above the plane of the bottom (1). Next, the worker moves the cover (6) to remove the step (6.2) from the coupling with the open groove (3.1). After that, the cover (b) is removed and placed near the hole (4) on the bottom (1).

Installation of the cover (6) is performed by the worker in the reverse order.

Assembly and disassembly of the cover (b) is carried out within the area of the bottom (1) without the need to move the worker to the slaughter area, which ensures maximum safety of the section's service.

Installation of fasteners (7) only at two points of the cover (b) eliminates the need to make a through hole (2.1) in the sidewall (2) along the cover (b), which increases the rigidity of the section structure at the place of installation of the cover (6).

The ability to fix the cover (6) inside the section allows you to reduce its area relative to the nearest analogue, which reduces the weight of the cover (b) without changing its thickness and manufacturing material.
