Abstract
The utility model discloses a detachable combined anchor cable rigging, which comprises upper riggings, lower riggings and fastening bolts. An integral is formed by the upper riggings and the lower riggings through the fastening bolts; upper rigging semi-frustum holes are arranged in the middle upper portions of the upper riggings; through holes are respectively arranged on the upper riggings on the left side and the right side of the upper rigging semi-frustum holes; lower rigging semi-frustum holes are arranged in the middle upper portions of the lower riggings and form an integral frustum through hole with the upper rigging semi-frustum holes; screw holes are respectively arranged on the lower riggings on the left side and the right side of the lower rigging semi-frustum holes; and convex keys and concave grooves are respectively arranged on the upper riggings and the lower riggings and mutually embedded. The detachable combined anchor cable rigging has the advantages of simple structure, reasonable design and capabilities of realizing reliable supporting and protection, convenient and rapid disassembly and one hundred percent of recycling, effectively eliminating potential safety hazard, and being suitable for installation and use of underground tunneling of various coal mines and coal mining tunnels.
Description
Technical field
The utility model relates to mine timbering anchoring apparatus, refers more particularly to a kind of removable combination anchor cable rigging.
Background technology
At present, the colliery is at the tunneling construction coal-face up and down during the lane, because the well depth roof pressure is big and geological conditions changes that to reach the roadway surrounding rock situation greatly abominable, must adopt steel band anchor pole and anchor cable combined supporting mode to strengthen the back supporting.When coal-face advanced in exploitation, goaf top plate freely collapsed better in the upper corner in order to make, and need dismantle anchor pole and cable bolting in advance.Anchor pole torque nut ratio is easier to dismounting, and the anchor cable rigging is then because roof pressure is excessive, even use special-purpose anchor cable demounting tool also to be difficult to dismounting.Because cable bolting can not all dismantle, cause that outstanding top appears in the goaf in the coal-face upper corner, and gas gathers easily and make the upper corner gas exceeding limit, and then strengthen hidden danger.Simultaneously, the abandonment of anchor cable rigging has also caused very big waste.
Summary of the invention
Goal of the invention of the present utility model, being to provide a kind of can effectively overcome the problems referred to above, and quick release is recycled and safe and reliable removable combination anchor cable rigging.
The technical solution of the utility model is such, and removable combination anchor cable rigging comprises rigging body, following rigging body and fastening bolt; The described rigging body of going up is connected as a whole with following rigging body by described fastening bolt; Described middle and lower part of going up the rigging body has rigging body half cone platform hole, described the going up on the rigging body in the described upward left and right sides, rigging body half cone platform hole has through hole, has rigging body groove and the protruding key of last rigging body before and after the lower, transverse of last rigging body; The described middle and upper part of rigging body down has down rigging body half cone platform hole, and forms a whole frustum through hole with the described rigging body half cone platform hole of going up; The described left and right sides, rigging body half cone platform hole down is described to have screw on the rigging body down, have down protruding key of rigging body and following rigging body groove before and after the upper lateral of following rigging body, and with the last rigging body groove and the protruding key tabling of last rigging body of last rigging body.
Characteristics of the present utility model are simple in structure, and are reasonable in design.Can realize that supporting is reliable, it is convenient to dismantle, and absolutely recycling effectively eliminates safe hidden trouble.Driving and coal cutting roadway installs and uses under the suitable all kinds of coal mine.

Wherein: the protruding key of rigging body on the rigging body groove, 7 on rigging body half cone platform hole, 5 through holes, 6 on rigging body on 1,2 times rigging bodies, 3 fastening bolts, 4,8 times rigging body half cone platform holes, 9 screws, 10 times protruding keys of rigging body, 11 times rigging body grooves.
The specific embodiment.
Shown in accompanying drawing 1,2, removable combination anchor cable rigging comprises rigging body 1, following rigging body 2 and fastening bolt 3; The described rigging body 1 of going up is connected as a whole with following rigging body 2 by described fastening bolt 3.
Shown in accompanying drawing 3,4,5, described middle and lower part of going up rigging body 1 has rigging body half cone platform hole 4, described the going up on the rigging body 1 in described upward 4 left and right sides, rigging body half cone platform hole has through hole 5, has rigging body groove 6 and the protruding key 7 of last rigging body before and after the lower, transverse of last rigging body 1.
Shown in accompanying drawing 6,7,8, the described middle and upper part of rigging body 2 down has down rigging body half cone platform hole 8, and forms a whole frustum through hole with described rigging body half cone platform 4 holes of going up; Described 8 left and right sides, rigging body half cone platform hole down are described to have screw 9 on the rigging body 2 down, have down protruding key 10 of rigging body and following rigging body groove 11 before and after the upper lateral of following rigging body 2, and with the last rigging body groove 6 and protruding key 7 tablings of last rigging body of last rigging body 1.
Before using installation, must on the screw thread of fastening bolt, coat lubricated glycerine, will go up the rigging body then and be connected as a whole by fastening bolt with following rigging body.This mainly is to prevent back trickle or tunnel moisture effect dismounting effect.Upper and lower rigging body groove and protruding key are set are in order to prevent that upper and lower rigging body from side occurring and cutting and slip away.During dismounting, only need a people just fastening bolt can be pulled down, and upper and lower rigging body is separated, and then reach the purpose that fast quick-detach reclaims.
