Abstract
An anchorage cable steel strand explosive-proofing cutting device comprising a hydraulic cylinder body (1), a movable cutting head (3) arranged on the front end of a hydraulic piston rod (2), and a static cutting head (4) matching the movable cutting head (3) is characterized in that: a liquid medium holding cavity (9) is arranged on the front end of the movable cutting head (3); the static cutting head (4) is a ring structure, the upper plane of the static cutting head (4) is a cutting edge surface matching the cutting edge of the movable cutting head, and the static cutting head (4) is inlaid into the bottom of the liquid medium holding cavity (9) through a connecting piece; a liquid intake pipe adaptor (6) arranged on the bottom of the static cutting head (4) is connected with a liquid source through a sheathing pipe (7) connected with the liquid intake pipe adaptor (6). The utility model has the advantages of ultimately solving the problem of spark easily produced during cutting a steel strand and further improving the safety of downhole operation in coal mines.
Description
(1) technical field
The utility model relates to a kind of wirerope, metal anchor cable (bar) shearing device, particularly a kind of explosion-proof cutter of anchor cable steel strand wires that is applicable to that operation is used under inflammable and explosive conditions such as colliery.
(2) background technology
At present, comparatively under the complicated situation, cable bolting is all adopted in its scope of operation and tunnel for deep production under coal mine and coal mining geology condition.This support process not only can reduce support cost, improve supporting intensity, also plays a good role for the security reliability that guarantees the face of adopting.Just because of this, just make this construction technology obtain applying widely.Mostly the cable bolting technology of prior art is earlier to carry out stretch-draw by the jack pair anchor cable, adopts the steel strand wires hydrashear cutter to cut off for the steel strand wires exposed parts after the stretch-draw more, unaffected during operation in underworkings to guarantee the workman.Because anchor cable uses the intensity of steel strand wires mostly more than 1860Mpa, its hardness all more than HRC45, can produce spark again inevitably in cutting-off process, this is breakneck for coal mine operation that gas is full of, very easily cause gas explosion, cause major hidden danger to production safety.
(3) summary of the invention
The purpose of this utility model provides a kind of explosion-proof cutter of anchor cable steel strand wires that spark produces of can stopping when steel strand wires are cut off with regard to being to overcome above-mentioned weak point of the prior art.
The purpose of this utility model can realize by following measure:
The explosion-proof cutter of anchor cable steel strand wires of the present utility model comprise cylinder body and be installed in the moving haircut of liquid presses piston pole front end and match with moving haircut decide haircut, the front end of wherein said moving haircut is provided with a liquid medium and holds the chamber; It is described that to decide haircut be a loop configuration, on it plane for and move the cutting edge face that the haircut cutting edge matches, this is decided haircut and is installed in liquid medium by connector and holds the bottom, chamber; Be provided with a feed tube joint in the bottom of deciding haircut, this feed tube joint is connected with the feed flow source by coupled protecting pipe.
Deciding haircut described in the utility model has the platen of feed tube joint and attachment screw by its bottom surface and is installed in liquid medium and holds in the installing hole that the bottom, chamber processes; The lower port of described protecting pipe is connected with the feed flow source by infusion tube.
Operation principle of the present utility model, manipulate method and advantage is as follows:
Earlier the steel strand wires exposed parts after the stretch-draw is held the upper shed in chamber via liquid medium, decide the central through hole of haircut, and be positioned at the protecting pipe of deciding haircut below and be inserted into cutter jaw place, start solution feed pump afterwards, make liquid medium (can be water or other liquid that can not light) pass through infusion tube continuously, protecting pipe and steel strand wires and decide space between the haircut and enter liquid medium and hold the chamber, hold the liquid level in chamber above moving when entering liquid medium, can start hydrashear cutter when deciding cutting edge place that haircut matches, by the moving haircut that drives by liquid presses piston pole with decide the cooperatively interacting of haircut with unnecessary steel strand wires cut-out.Because its cutting edge position is to carry out all the time, thereby also just from solved the steel strand wires cutting-off process, easily produce the problem of spark at all in cutting off the course of work, make the security of underground work be able to further raising in liquid medium.
(4) description of drawings
Accompanying drawing is a front view of the present utility model.
(5) specific embodiment
The utility model is done with detailed description below with reference to embodiment (accompanying drawing):
As shown in the figure, the moving haircut 3 that the explosion-proof cutter of anchor cable steel strand wires of the present utility model comprises cylinder body 1 and is installed in liquid presses piston pole 2 front ends, with match with moving haircut 3 decide haircut 4, the cutting edge position of wherein said moving haircut 3 front ends is provided with a liquid medium and holds chamber 9; It is described that to decide haircut 4 be a loop configuration, on it plane for and move the cutting edge face that the haircut cutting edge matches, this is decided haircut 4 and has the platen 5 of feed tube joint 6 and attachment screw by its bottom surface and be installed in liquid medium and hold in the installing hole that 9 bottoms, chamber process; Described feed tube joint 6 is connected with the feed flow source with the infusion tube 8 that is connected with the protecting pipe lower port by coupled protecting pipe 7.
Claims (3)
1, the explosion-proof cutter of a kind of anchor cable steel strand wires, it comprise cylinder body (1) and be installed in the moving haircut (3) of liquid presses piston pole (2) front end and match with moving haircut (3) decide haircut (4), it is characterized in that: the front end of described moving haircut (3) is provided with a liquid medium and holds chamber (9); It is described that to decide haircut (4) be a loop configuration, on it plane for and move the cutting edge face that the haircut cutting edge matches, this is decided haircut (4) and is installed in liquid medium by connector and holds bottom, chamber (9); Be provided with a feed tube joint (6) in the bottom of deciding haircut (4), this feed tube joint (6) is connected with the feed flow source by coupled protecting pipe (7).
2, the explosion-proof cutter of anchor cable steel strand wires according to claim 1 is characterized in that: describedly decide haircut (4) and have the platen (5) of feed tube joint (6) and attachment screw by its bottom surface and be installed in liquid medium and hold in the installing hole that bottom, chamber (9) processes.
