Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic supports, in particular to a hydraulic support. Background Art

[0002] With the large-scale mining of coal resources, the current coal resources are becoming less and less. Some coal seams that were previously hidden in buildings, roads, and villages and were considered difficult to mine are now attracting more and more attention. Filling mining is suitable for such coal mines that are not suitable for mining. Filling mining is to fill water, mud, stone and other fillers while mining. Filling mining requires effective shielding of the support area and effective compaction of the filler to prevent the filler from sliding into the safe area of ​​the equipment. However, the existing hydraulic support cannot effectively compact the filler, which can easily cause the filler to slide and affect the safety of personnel.

[0003] Therefore, how to propose a hydraulic support that can effectively compact the filler has become a problem that needs to be solved urgently. Utility Model Content

[0004] The utility model provides a hydraulic support, which solves the problem in the related art that the filler is easy to slide off due to the inability to effectively compact the filler.

[0005] To this end, the first object of the utility model is to provide a hydraulic support.

[0006] In view of this, the technical solution of the first aspect of the utility model provides a hydraulic support, including: a support beam; a side baffle connected to the support beam; a first telescopic component, one end of which is connected to the first position of the support beam, and the other end is connected to the side baffle; a second telescopic component, one end of which is connected to the second position of the support beam, and the other end is connected to the side baffle; wherein the first telescopic component and the second telescopic component can be telescopic to adjust the distance between the side baffle and the support beam.

[0007] The hydraulic support provided by the utility model includes a support beam, which supports the top wall of the tunnel, thereby forming a safe area so that construction workers can work safely in the tunnel.

Therefore, in the utility model, the side baffle is connected to the support beam through the first telescopic assembly and the second telescopic assembly, and the first telescopic assembly and the second telescopic assembly can adjust the spacing between the side baffle and the support beam by their own telescopic. On the one hand, by arranging the side baffle on one side of the support beam, the side baffle can be used to block fillers and sand and gravel. On the other hand, the first telescopic assembly and the second telescopic assembly are arranged to replace the ordinary connecting rod in the related art, and the spacing between the side baffle and the support beam can be changed by the self-adjustment of the first telescopic assembly and the second telescopic assembly, thereby expanding the scope of application of the hydraulic support. At the same time, the first telescopic assembly and the second telescopic assembly drive the side baffle to move away from the support beam, which can effectively compact the filler, and the first telescopic assembly and the second telescopic assembly have a squeezing effect on the filler. In addition, the first telescopic assembly and the second telescopic assembly are respectively connected to the first position and the second position of the support beam, and the first position and the second position are different, that is, the first telescopic assembly and the second telescopic assembly are respectively connected to different positions of the support beam.
