Technical Field

The utility model relates to a fully mechanized mining face hydraulic support, in particular to an auxiliary device for retracting a side guard plate of a face support to reset.

Background

In the process of withdrawing the bracket, the transportation width of the bracket needs to be controlled within 1700mm due to the limitation of underground transportation conditions, so that the bracket side guard needs to be almost completely withdrawn and reset to meet the transportation requirement. Normally, the transportation width dimension of the ZF10000/21/38 type bracket is 1660-1860 mm, and the bracket used on the working face has long service time, so that a plurality of bracket side guard jacks can not completely withdraw the side guard for resetting, and the operation can be realized by means of external force. The method adopted in the prior art is that 2 single columns are used at the same time and are propped against the two sides of the side guard of the bracket, and the single columns are used for completely jacking the side guard back and then are firmly bound by steel wire ropes.

The method has large labor load on field workers, the single column is suspended for operation, high requirements are placed on the positions of the acting points at the two ends of the single column, the support can incline to deviate from a monorail crane transportation route or the single column can slip to hurt people, and the defect is obvious. Therefore, the optimization and improvement of the method are urgently needed.

SUMMERY OF THE UTILITY MODEL

The utility model overcomes the defects of the prior art and provides an auxiliary device for retracting the side guard plate of the working face support to reset, so that the labor intensity of workers is reduced, and the working efficiency and the safety coefficient are improved.

In order to achieve the above object, the present invention is achieved by the following technical solutions.

The utility model provides an auxiliary device for withdrawing working face support side guard board resets, includes the stull, the stull has the level bottom surface, the equal fixedly connected with stand in bottom surface both sides of stull, stand perpendicular to stull bottom surface, the medial surface fixedly connected with hydraulic jack of one of them stand, the piston end of hydraulic jack stretches out towards the direction level of another stand, the stull bottom surface is connected with the mount, hydraulic jack is located the mount, the medial surface of stand is the vertical plane.

Furthermore, the cross brace and the upright post are both channel steel.

Furthermore, an inclined strut is connected between the cross strut and the upright post.

Furthermore, the fixing frame is a U-shaped frame body, and the middle part of the hydraulic jack is arranged on the fixing frame in a supporting mode.

Furthermore, the fixing frame is welded with the cross brace.

Compared with the prior art, the utility model has the following beneficial effects:

1. the operation is simple, and the operation can be realized only by placing the channel steel frame on the top beam of the bracket and then hanging the jack.

2. The single column is not used, the operation of manually lifting the single column is not needed, and the labor intensity is low.

3. The support is not inclined integrally, the whole operation link only needs about 10 minutes, and the device is safe and efficient.

The single column does not need to be lifted manually, the labor intensity of workers is greatly reduced, operating personnel can have wider withdrawing space, the personnel standing position is more reasonable, the heavy object does not need to be lifted continuously manually for a long time, and the operation danger source is reduced.

Detailed Description

In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail with reference to the embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model. The technical solution of the present invention is described in detail below with reference to the embodiments and the drawings, but the scope of protection is not limited thereto.

As shown in fig. 1-2, the auxiliary device for retracting the side guard plate of the working face support to reset comprises a cross brace 1 and an upright post 2, wherein the cross brace 1 and the upright post 2 are both channel steel. The stull 1 has the horizontal bottom surface, stand 2 has all been welded to the bottom surface both sides of stull 1, stand 2 perpendicular to stull bottom surface, the medial surface of stand 2 is the vertical plane. An inclined strut 5 is connected between the cross strut 1 and the upright post 2. The medial surface fixedly connected with a miniature hydraulic jack 3 of one of them stand 2, hydraulic jack 3's piston end stretches out towards the direction level of another stand 2, the welding of 1 bottom surface of stull has mount 4, mount 4 is the support body of U-shaped, and hydraulic jack 3's middle part is put up on the mount.

The total length of the device is 2830mm, and the weight of the device is about 30 kg. In order to strengthen the strength of the channel steel of the transverse strut 1 and avoid bending deformation in the use process, a rib plate is welded on the middle channel steel of the transverse strut 1 in a repair mode.
