Description

Technology area

The technical solution relates to mechanical engineering, namely, to work as part of the technological chain of continuous conveyor transport of rock mass and to ensure the connection of a scraper loader and a telescopic belt conveyor.

Prior art

It is known from the prior art, selected as the closest analogue, a matching device, which contains a movable frame with hydraulic jack supports and guides, a carriage with an end drum of the belt conveyor, the roller supports of which are mounted on the guides. The carriage is made of a rigidly bolted main frame and a rear support frame. The frame of the rear support of the carriage is connected by a hydraulic jack for longitudinal movement with the movable frame. Between the stepped side walls of the carriage main frame made from below, the end drum of the belt conveyor is located. The axis of the end drum is fixed with removable clamps in the side walls and is located in C-shaped saddles, each of which is made at the end of the side wall, under its horizontal protrusion, which is equipped with elements of a detachable connection with the end of the leading part of the carriage and is displaced downward with overlapping of the direct entry / exit drum axles in Conforming saddles (LLC "CENTER OF MINING MACHINE BUILDING" Matching device MTL-1200S.00.00.000RE. Operation manual).

Disadvantages of the closest analogue

As a rule, during the initial installation of the matching device, the end drum of the belt conveyor is already mounted in the carriage. If urgent dismantling is necessary, it is difficult for personnel in the space limited by the top-mounted drive frame, transition section or sieve section of the scraper conveyor-reloader, after disconnecting and withdrawing the rear support frame with a hydraulic jack for longitudinal movement, it is difficult to hold the shaft axis after the winch unlocks, and gradually move the end drum along shaped groove with an offset downward, and then bring it out from under the horizontal protrusion.

The technical solution is based on the following task:

Provide the possibility of transportation by the frame of the rear support of the carriage of the end drum along the guides during its installation and dismantling.

As a result of solving the problem, a technical result will be obtained: the possibility of using the device's own drive to compensate for the power load of personnel.

Achievement of the declared technical result will provide the technical solution with consumer properties: reduced labor costs and increased safety during installation and dismantling of the end drum.

Disclosure of a technical solution

The above-mentioned essential features of a utility model, different from the closest analogue, are necessary and sufficient in all cases to which the scope of legal protection of the utility model extends.

In addition, it is offered:

on the flats of the end parts of the end drum axis, fix removable bushings with radial through holes made in them;

the lower level of the side wall, which is made with a saddle, should be placed below the point of conjugation of the roller support with the guide of the movable frame.

The technical solution is illustrated 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 applicability

Corner brackets (17) and removable bushings (23) are elements of the matching device and are used as its component parts when mounting and dismounting the end drum (9).

The wall thickness of the seat (19) increased by the bar (32), which is a continuation of the side wall (21), is less than the distance between the end drum (9) and the guide (3) of the main frame (1).

Placing the lower level of the side walls (21) below the roller support (20) allows the side walls (21) to act as a limiter for lateral displacement of the corner bracket (17) when it is mounted on the flange (14).

Dismantle the end drum (9) in the following order:

carry out a full movement of the hydraulic jack of the longitudinal movement (8), installed on the roller supports (6), the frame of the rear support of the carriage (5) with the main frame of the carriage (4) and the drive of the scraper loader (28) installed on it, and then release the end drum (9 ) belt conveyor from the belt (figure 1);
