Description

Technical Field

[0001] This utility model relates to the field of supports, and in particular to a retaining wall support for filling and opening. Background Technology

[0002] There are four methods for managing the roof of underground coal mining faces: total collapse, support, slow subsidence, and backfilling. Backfilling involves filling the goaf with non-combustible materials such as waste rock to control roof collapse and achieve safe roof management. Retaining wall supports are required during backfilling mining.

[0003] Most existing retaining wall supports are directly fixed structures. When working with retaining walls of different sizes, they need to be customized according to the volume of the wall. Customized supports need to be welded in multiple places, so the support strength is large, they are easy to bend, the overall strength of the support is low, they are difficult to provide effective support, and the installation is relatively troublesome.

[0004] Therefore, since most of the existing retaining wall supports are directly fixed structures with high support strength but are prone to bending, a filling-type retaining wall support can be designed to solve the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing retaining wall supports, which are mostly directly fixed structures, when working on retaining walls of different sizes, it is necessary to customize the supports according to the volume of the wall. Therefore, customized supports need to be welded in multiple places, resulting in high support strength, easy bending, low overall strength of the support, difficulty in providing effective support, and complicated installation.

[0006] The technical solution of this utility model is as follows: a filling opening retaining wall support, comprising a double-sided arc plate, a front bolt, a hollow plate, a sliding plate, a connecting frame, a connecting block, a vertical push rod, a fixed seat, a rear bolt, a connecting plate, a rear rotating connecting seat, an inclined push rod, a front rotating connecting seat, a spring damper, and a hollow semi-circular top. The rear end of the double-sided arc plate is provided with a front bolt, the upper end of the front bolt is provided with a hollow plate, the hollow plate is provided with a sliding plate, the upper end of the sliding plate is provided with a connecting frame, the lower end of the connecting frame is provided with a connecting block, the lower end of the connecting block is provided with a vertical push rod, the lower end of the vertical push rod is provided with a fixed seat, the front end of the double-sided arc plate is provided with a rear bolt, the upper end of the rear bolt is provided with a connecting plate, the rear end of the connecting plate is provided with a rear rotating connecting seat, the rear end of the rear rotating connecting seat is provided with an inclined push rod, the rear end of the inclined push rod is provided with a front rotating connecting seat, the upper end of the connecting frame is provided with a spring damper, and the upper end of the spring damper is provided with a hollow semi-circular top.

[0007] Preferably, the main support is set up to provide vertical and diagonal support, and protection is provided for the top.

[0008] Preferably, the rear end of the double-sided arc plate is rotatably connected to the front end of the plate via a front bolt and a hollow plate, and the front end of the double-sided arc plate is rotatably connected to the rear end of the plate via a rear bolt and a connecting plate.

[0009] Preferably, the hollow board, the skateboard, and the connecting frame are configured as a whole, with the skateboard and the connecting frame being fixedly connected, and the skateboard being slidably connected to the hollow board.

[0010] Preferably, the connecting block, vertical push rod, and fixing seat are configured as a whole, and there are three sets in total.

[0011] Preferably, the rear rotating connecting seat is located at the rear end of the connecting plate, the front rotating connecting seat is located at the front end of the hollow plate, and an inclined push rod is rotatably connected between the rear rotating connecting seat and the front rotating connecting seat. The rear rotating connecting seat, the inclined push rod and the front rotating connecting seat are set as a whole, and there are two sets of them.

[0012] Preferably, the connecting block, vertical push rod, and fixed seat are arranged in a staggered manner with the rear rotating connecting seat, oblique push rod, and front rotating connecting seat.

[0013] Preferably, four spring dampers are provided and fixed to the upper end of the connecting frame. A hollow semi-circular top is connected through the spring damper, and the hollow semi-circular top is in the shape of a top arc.

[0014] The beneficial effects of this utility model are:

[0015] 1. Vertical and diagonal push rods provide vertical and diagonal support. Simultaneously, the double-sided arc-shaped plates are rotatably connected to the hollow plate via front bolts and to the connecting plate via rear bolts. This allows for adjustments to the contact area with the ground, increasing support strength. The diagonal and vertical push rods are interlaced to form a triangle, which provides stability and enhances the support effect. This overcomes the shortcomings of existing retaining wall supports, which are mostly directly fixed structures requiring welding in multiple places. This results in high support strength, easy bending, and low overall strength, making effective support difficult and installation cumbersome.

[0016] 2. By setting up double-sided arc plates that are rotatably connected to the hollow plate via front bolts, and simultaneously rotatably connected to the connecting plate via rear bolts, the area in contact with the ground can be changed to improve support strength. The fixed seat fixes the vertical push rod, and the vertical push rod fixes the connecting block. The vertical push rod extends and retracts, driving the connecting frame and sliding plate to move along the hollow plate, thereby adjusting the support height. The rear rotating connecting seat, the oblique push rod, and the front rotating connecting seat are rotatably connected. The oblique push rod extends and retracts to fix the support. The oblique push rod and the vertical push rod are set in an alternating configuration, and the oblique push rod and the vertical push rod are combined to form a triangle. The triangle has stability and can enhance the support effect. The spring damper is used for shock absorption, and the hollow semi-circular top is used for anti-collision protection. This completes the design of the retaining wall support for filling and mining. Attached Figure Description

This allows for adjustments to the area in contact with the ground, increasing support strength. The diagonal push rods 12 and vertical push rods 7 are staggered to form a triangle, which provides stability and enhances the support effect. This overcomes the shortcomings of existing retaining wall supports, which are mostly directly fixed structures requiring welding in multiple places, resulting in high support strength, easy bending, low overall strength, and difficulty in providing effective support, as well as cumbersome installation.
