Description

Technical Field

[0001] This utility model belongs to the technical field of advanced hydraulic support equipment, and specifically relates to an advanced hydraulic support side adjustment device. Background Technology

[0002] The ZQH2×5100 / 28 / 43 advanced hydraulic support is mainly composed of longitudinal beams, cross beams, columns, pushing jacks, and side-adjusting jacks. It adopts a staggered structure of two sets of A and B frames (yellow and white) that push and pull against each other, enabling self-moving movement. It is suitable for alley widths of 5000mm-5800mm.

[0003] During normal support relocation, due to its top-heavy nature, the support will often tilt to the heavier side, frequently resulting in the advanced hydraulic support falling onto the coal face. When using the side-adjusting jacks fixed to the crossbeams to adjust the tilt of the support, the limited length makes it impossible to effectively adjust the tilt of the advanced hydraulic support. Therefore, it is necessary to manually use a single column to strike one end of the column against the coal face and the other end against the longitudinal beam to right the advanced hydraulic support. However, this requires personnel to lower all the columns of the advanced hydraulic support and work under the support, posing a significant safety risk. Utility Model Content

[0004] The purpose of this invention is to provide a side adjustment device for advanced hydraulic supports, which solves the technical problem of the advanced hydraulic supports tipping over during actual support relocation.

[0005] This utility model is achieved using the following technical solution: An advanced hydraulic support side adjustment device includes columns, a plate jack, a crossbeam ring, and a side adjustment jack. One end of the plate jack is fixed to the crossbeam ring, and the other end is fixed to the side of the transfer machine trough. The plate jack receives return fluid from the hydraulic support valve group. The crossbeam ring is located on the lower side of the middle of the crossbeam. The side adjustment jack is fixedly installed on one side of the crossbeam along the axial direction. Two columns are vertically arranged at both ends of the crossbeam. The crossbeam spans across the top of the transfer machine.

[0006] The insert plate jack is equipped with a lifting ring. When the advanced hydraulic support tilts, the position of the insert plate jack, the crossbeam ring, and the transfer machine trough side are first fixed by operating the lifting ring. The side adjustment jack is then fully retracted to prevent it from getting caught on the side netting. Then, the crossbeam and longitudinal beam to be adjusted are loosened, and the insert plate jack is retracted. During the retraction of the insert plate jack, the crossbeam and longitudinal beam are straightened. Then, the upright column is tightened to complete the movement of the advanced hydraulic support. This utility model avoids using a single column to ram the advanced hydraulic support from the side during use, effectively reducing safety risks.

[0007] Preferably, the insert jack and the side-adjustment jack are remotely extended and retracted via electro-hydraulic control. In practice, the side-adjustment jack and the insert jack can be remotely operated using a remote control to achieve long-distance side-adjustment of the hydraulic support.

[0008] Compared with the prior art, the present invention has the following advantages: In actual use, the present invention effectively reduces the input of manpower. The work that usually requires 4 people can now be completed by only 1 person. At the same time, it greatly reduces the time for handling the dismantling of the frame, effectively improves the safety factor, and reduces the safety risk of personnel operating under the frame.

[0017] An advanced hydraulic support side adjustment device includes a column 1, a sliding plate jack 4, a crossbeam ring 8, and a side adjustment jack 6. One end of the sliding plate jack 4 is fixed to the crossbeam ring 8, and the other end is fixed to the side of the transfer conveyor 5. The sliding plate jack 4 receives return fluid from the hydraulic support valve group. The crossbeam ring 8 is located on the lower side of the middle of the crossbeam 2. The side adjustment jack 6 is fixedly installed on one side of the crossbeam 2 along its axial direction. Two columns 1 are vertically arranged at both ends of the crossbeam 2. The crossbeam 2 spans across the transfer conveyor 5. The insert jack 4 and the side adjustment jack 6 are remotely extended and retracted via electro-hydraulic control.

[0018] The working principle is as follows: The insert jack 4 is equipped with a lifting ring 7. When the advanced hydraulic support tilts, the position of the insert jack 4, the crossbeam ring 8, and the side of the transfer machine 5 are first fixed by operating the lifting ring 7. The side adjustment jack 6 is then fully retracted to prevent it from getting caught on the side net. Then, the crossbeam 2 and longitudinal beam 3 of the support to be adjusted are lowered and loosened. The insert jack 4 is then retracted. During the retraction of the insert jack 4, the crossbeam 2 and longitudinal beam 3 are straightened. Then, the column 1 is tightened to complete the movement of the advanced hydraulic support. This utility model avoids the use of a single column to ram the advanced hydraulic support from the side during use, effectively reducing safety risks.

[0019] Specifically, the side-adjustment jack 6 and the insert jack 4 can be remotely operated using a remote control to achieve remote side-adjustment of the hydraulic support.

[0020] In this embodiment, one end of the 11000 bracket insert plate jack 4 is fixed to the bottom of the crossbeam ring 8 with the lifting ring 7, and the other end is fixed to the side of the transfer machine 5 with the lifting ring 7. Return fluid is connected to the jack from the hydraulic support valve group, and the remote extension and retraction of the insert plate jack 4 is realized through electro-hydraulic control.
