Problems solved by technology

After the mining is completed, it is necessary to disassemble and recycle the pallets and slings. However, the existing anchor cable support structure is under high-pressure mine pressure. Because the safety of the support must be considered in the early stage of construction, the over-set Large rigid abutting force will cause the problem that the windlass cannot make the rigging fall off from the anchor cable, and it will be difficult to recover the pallet, anchor cable ball, etc.

Embodiment Construction

[0055] Embodiments of the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, and therefore are only examples, rather than limiting the protection scope of the present invention.

[0056] Such as Figure 1-3 As shown in , the anchor withdrawal device includes an anchor cable 2 fastened in the rock formation of the roadway 1, the outer end of the anchor cable 2 extends out of the roadway 1, and the outer wall of the anchor cable 2 outside the roadway 1 is covered with Pallet 3, on the outside of the pallet 3 is provided with a sling 4 fastened on the anchor cable 2, and a telescopic pressure relief assembly is installed on the outside of the anchor cable 2 between the pallet 3 and the rigging 4 5. The two ends of the telescopic pressure relief component 5 are respectively used to press agains...

Abstract

The invention relates to the technical field of underworkings supporting, particularly to a device for quickly recovering an anchor rope tray and an anchor rope ball under high pressure, in particularan anchor withdrawing and yielding device. The anchor withdrawing and yielding device comprises an anchor rope fastened in a roadway rock stratum; the outer end of the anchor rope extends outside a roadway; the outer side wall of the anchor rope outside the roadway is sleeved with a tray; a gear tightly sleeved on the anchor rope is arranged on the outer side of the tray; a telescopic yielding module is mounted on the outer side of the anchor rope between the tray and the gear; and the two ends of the telescopic yielding module are used for abutting against the outer end surface of the tray and the inner end surface of the gear. An oil cylinder yielding structure can be adopted to quickly and simply recover such gears as the tray and an anchor rope ball under the working condition of highmine pressure to achieve low construction difficulty; and meanwhile, the device can control and set the oil pressure as needed to effectively protect the anchor rope during staggered shearing of theanchor rope on the roadway rock stratum, so that the shearing probability of the anchor rope is reduced, and the use safety is higher.

Description

technical field [0001] The invention relates to the technical field of underground roadway support, in particular to a device for quickly recovering anchor cable trays and anchor cable balls under high pressure, especially an anchor withdrawal device for pressure relief. Background technique [0002] In the process of coal mining and production, in order to improve the safety of construction, the anchor cable roadway support is usually used to reinforce the roadway. After the construction is completed, the anchor cable is in a tensioned state. After the mining is completed, it is necessary to disassemble and recycle the pallets and slings. However, the existing anchor cable support structure is under high-pressure mine pressure. Because the safety of the support must be considered in the early stage of construction, the over-set The large rigid abutting and pressing force will cause the problem that the windlass cannot make the rigging fall off from the anchor cable, and it ...
