Abstract
The utility model discloses a kind of termination point of anchor rod protective device.Described termination point of anchor rod protective device, comprise buckle, flexible steel twisted wire, link, cannelure, clamp nut, hanging wire hole, anchor rod pallet board.The utility model utilizes flexible steel twisted wire to be connected with buckling in the hanging wire hole be placed on the link of cannelure and anchor rod pallet board, until utilize in roadway construction process clamp nut and anchor rod pallet board termination point of anchor rod is fastening after, be about to buckle and be hung on lane wall anchor net or other lane wall fixtures.In time there are abnormal conditions and make the clamp nut of termination point of anchor rod and anchor rod pallet board outwards dish out at a high speed in lane wall; the outer throwing that termination point of anchor rod protective device retrains clamp nut and anchor rod pallet board in time by passive radial load is moved; effectively avoid the clamp nut of high-speed motion and anchor rod pallet board to the injury of staff and to the infringement about down-hole facilities and equipment, reach the object of protection staff and underground equipment.
Description
Technical field
The utility model belongs to mine safety engineering field, particularly a kind of termination point of anchor rod protective device.
Background technology
China locates in existing colliery more than 1.2 ten thousand, and coal total output is 36.92 hundred million tons, and annual advance tunnel, colliery is about 7000km.China's coal-mine is based on pit mining on the whole, have the advantages that the colliery large tunnelling amount of fecund amount is large, and roadway support is the important guarantee of Safety of Coal Mine Production, facts have proved: bolt support is the main support form of current coal mine roadway.But the outside impelling phenomenon of the anchor rod anchored end of frequent appearance in the tunnel that large Surrounding Rock Strength is low is pressed in bolt support on ground, the anchored end that high-speed projectile goes out forms very large harm to staff and underground equipment, but does not still well administer preventive action at present.Based on above-mentioned situation, practical in the urgent need to one, easy to use, long-lived termination point of anchor rod protective device, to reach the object of safeguard work personnel and facilities and equipment safety.
Utility model content
The object of the utility model embodiment is to propose a kind of termination point of anchor rod protective device; flexible steel twisted wire is utilized to be connected with buckling in the hanging wire hole be placed on the link of cannelure and anchor rod pallet board; until utilize in roadway construction process clamp nut and anchor rod pallet board termination point of anchor rod is fastening after, be about to buckle and be hung on lane wall anchor net or other lane wall fixtures.In time there are abnormal conditions and make the clamp nut of termination point of anchor rod and anchor rod pallet board outwards dish out at a high speed in lane wall; the outer throwing that termination point of anchor rod protective device retrains clamp nut and anchor rod pallet board in time by passive radial load is moved; effectively avoid the clamp nut of high-speed motion and anchor rod pallet board to the injury of staff and to the infringement about facility, reach the object of protection staff and mine facility equipment.To achieve these goals, the utility model adopts following technical scheme:
A kind of termination point of anchor rod protective device, comprising:
Buckle, flexible steel twisted wire, link, cannelure, clamp nut, hanging wire hole, anchor rod pallet board, described link is placed in the cannelure of described clamp nut outside, and can rotate around cannelure when not departing from cannelure, described hanging wire hole is placed in the middle part of anchor rod pallet board, described in buckle and be connected with link and hanging wire hole by flexible steel twisted wire.
Preferably, described in buckle and processed by stainless steel, can withstand shocks effect, flexible durable.
Preferably, described flexible steel twisted wire is processed by stainless steel twisted wire, and convenient bending, can withstand shocks effect.
Preferably, described clamp nut outside has the cannelure that can hang link, and is processed by steel.Compared with existing similar device, the utility model tool has the following advantages:
The termination point of anchor rod protective device that the utility model is addressed, specifically buckle, flexible steel twisted wire, link, cannelure, clamp nut, hanging wire hole, anchor rod pallet board, wherein buckle and processed by stainless steel, can withstand shocks effect, flexible durable, is hung on the wall fixed object of Bi Maowanghuo lane, lane; Flexible steel twisted wire is processed by stainless steel twisted wire, and convenient bending, can withstand shocks effect, carries out operative constraint to clamp nut and anchor rod pallet board; Clamp nut outside has the cannelure that can hang link; and processed by steel; the fastening work to termination point of anchor rod is completed under not affecting by link; the operative constraint of link can be subject to during outside high-speed projectile by lane wall dilatancy simultaneously; the termination point of anchor rod that effectively can control to cause because tunnel is abnormal flies out accident; efficient cooperation mutually eventually through all parts gives full play to respective function, reaches the object of protection staff and mine facility equipment.
