Description

Technical field

The technical solution relates to conveyor transport and can be used in the inspection sections of the gutter of the scraper conveyor.

State of the art

Known as an analogue section is the inspection trough of a mine scraper conveyor which contains a bottomhole and blocking sidewalls, rigidly interconnected by lower and upper bottoms. The upper bottom is made with a viewing hole, the edges of which have shoulders. The bottomhole sidewall is made with a through hole. The removable cover is mounted on the shoulders and in the through hole of the bottomhole sidewall, the height of which is greater than the thickness of the removable cover by the amount of clearance S sufficient to install the removable cover through the through hole of the bottomhole sidewall. The inspection hole and the removable cover are made in a trapezoidal shape. The shift of the obstruction edge of the removable cover up is impossible due to its interaction with the obstruction sidewall and the placement of its part in the through hole of the obstruction sidewall.

A quick-release latch is installed on the outside of the bottomhole sidewall, with which a removable cover is fixed.

The latch is made in the form of a rod located in a vertical hole on the outside of the bottomhole sidewall. The rod is made with a turnkey head and a radial protrusion (stroke limiter), which can contact with the stop outside the bottomhole sidewall.

Holes are made in the cover for interacting with the mounting tool.

The removable cover is installed through the through hole of the bottomhole sidewall due to the gap S, 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 bottomhole sidewall on the shoulders to the stop in the blocking sidewall and pairing with a through hole made in the blocking sidewall.

The removable cover is fixed against displacement by a rod installed in a vertical hole on the outside of the bottomhole sidewall. To prevent loss, the rod is rotated with a key behind the head so that its radial protrusion begins to interact with the bottomhole sidewall stop.

Removing the removable cover is carried out in reverse order by removing the latch. To extend the removable cover, a dismantling tool is used, laying it in the holes at the end of the cover from the outside of the bottomhole sidewall. [one]

The disadvantages of this design include:

- a high probability of jamming of the cover from deforming forces to the bottomhole side shelf in the area of the through hole in which the cover should move freely. The side of the gutter of the scraper conveyor, in which a long through groove is made, is a weak point and, under load, it will be deformed that part of the groove with the groove;

- for mounting / dismounting the cover, maintenance personnel need a large distance to the side of the gutter equal to the length of the cover, i.e. almost the width of the gutter itself, it is necessary to specifically clean the area to pull out the lid, which is associated with the risk of rock collapse and personal injury.

The basis of creating a utility model is the task:

- increase the rigidity of the section at the installation site of the cover;

- ensure maximum safety of the service section.

Technical result

Creating a simple and convenient design of the inspection trench section of the mine scraper conveyor, both in manufacturing and in maintenance. Consumer properties: improving the state of safety and reducing the number of repairs.

Industrial applicability

The technical solution is presented on the example of a section of the inspection groove of the scraper conveyor, the side walls (2) and (3) of which are made curved and rigidly connected by two bottoms (10) and (1) (Fig. 2 and Fig. 6).

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

The bottom (1) is presented with a viewing hole (4) (Fig. 3 and Fig. 4) of a rectangular shape in which the shoulders (4.1) are made opposite. Open shoulders (4.2) are made above the shoulders (4.1) in the lateral surface of the hole (4) (Fig. 1 and Fig. 6).

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

Sidewall (2) is rigidly connected to the share (5) in which openings (5.1) are made combined with holes (9.1) (Fig. 2 and Fig. 6).

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

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

The latch (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 an elastic bracket (8) at the other end (Fig. 5).

In the closed position, the cover (6) is installed in the inspection hole (4) on the shoulders (4.1). The step (6.2) is conjugated with an open groove (3.1) so that the horizontal surface of the groove (3.1) restricts the upward movement of the step (6.2). On the side of the sidewall (2), the cover (6) is fixed by two vertically mounted identical rods (7), each of which is installed through the opening (5.1), respectively, in the through hole (9.1) and the through hole (2.1) of the sidewall (2), so that the step (7.2) of each rod (7) is installed above the bottom of the open groove (6.1) and restricts the movement of the cover (6) upward.

To exclude the arbitrary exit of the step (7.2) from the open groove (6.1), as a result of vibration that occurs in the operating mode of the conveyor, the rod (7) is locked by a vertically mounted elastic bracket (8), which is paired with an annular groove (7.1) and placed in the gap (5.3).

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

To remove the cover (6), the worker first removes the bracket (8) from the annular groove (7.1) of each rod (7) and through the opening (5.1) removes the rod from the holes (9.1) and (2.1) until the open groove (6.1) is completely released from steps (7.2). An assembly tool is inserted into the open groove (4.2) by the worker until it is mated to the surface of the open groove (6.3), then the end of the cover (6) with open grooves (6.1) is lifted by the installation tool at an angle sufficient to be gripped by the hands above the bottom plane (1). Next, the worker moves the cover (6) until the step (6.2) is removed from the interface with the open groove (3.1). Then the cover (6) 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.

Installation and dismantling of the cover (6) is carried out within the bottom area (1) without the need for the employee to move to the bottomhole zone, which ensures maximum safety of the section service.

The installation of clamps (7) at only two points of the cover (6), eliminates the need for a through hole (2.1) in the sidewall (2) along the cover (6), which increases the rigidity of the section at the installation site of the cover (6).

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