Abstract
The invention relates to a recyclable hydraulic constant-resistance device for an anchor cable. The hydraulic constant-resistance device for the anchor cable comprises a hydraulic constant resistor, an anchor unloading sleeve and a threaded jaw, wherein through the adoption of a constant pressure relief principle of the hydraulic constant resistor, constant supporting force in the working process of the anchor cable is realized; the hydraulic constant resistor is mounted between an anchor cable lock and a tray; the threaded jaw is embedded in a lock sleeve of the anchor cable lock to tighten the anchor cable; during recycling, the anchor unloading sleeve extends into the hydraulic constant resistor to be connected with the threaded jaw through threads; the bottom of the threaded jaw is an external thread; the top of the anchor unloading sleeve is an internal thread; and a supporting structure can be arranged at the bottom of the anchor unloading sleeve. Through tensioning the anchor unloading sleeve, the threaded jaw is driven to move to be detached, and then the constant-resistance device for the anchor cable is recycled to be reused; therefore, the supporting cost is reduced.

Background technology
Anchor cable has the features such as supporting capacity is high, anchorage depth is large, easy for installation, along with the continuous increase of roadway support degree of difficulty, due to the drastic deformation of country rock and not mating of conventional anchor cable extension property, in addition the effect of shock loading, anchor cable is disrumpent feelings, fastening invalidation happens occasionally, and produces fall of ground hidden danger.For problems, many New Anchor Cables are developed, as constant-resistance anchor cable, quake-proof anchor rope, allow and press anchor cable etc., and good result is achieved in engineering practice, but mostly such anchor cable is to adopt the frictional resistance between each component to realize the constant of Support Resistance in surrouding rock deformation, stability under working conditions is poor, and general comparatively complicated, the not reproducible utilization of structure, support cost is higher.A kind of recyclable hydraulic anchor cable permanent resistance install, directly can install on anchor cable, adopt the constant pressure release principle of fluid pressure type constant-resistance device, can realize in surrouding rock deformation, anchor cable provides continual and steady Support Resistance, can solve the Surrounding Rock Control problem of roadway with large deformation preferably.This device is furnished with anchor cable and moves back anchor structure simultaneously, so that this device is recyclable, recycling, reduces support cost.
Summary of the invention
The object of the present invention is to provide and a kind ofly realize that cable bolting power is constant, duty is reliable, the convenient anchor cable permanent resistance install reclaimed, to solve the support issues in large deformation, high roof fall risk tunnel.
To achieve these goals, the technical solution adopted in the present invention:
Recyclable hydraulic anchor cable permanent resistance install, by fluid pressure type constant-resistance device, move back anchor sleeve pipe and screw thread claw forms, during installation, its fluid pressure type constant-resistance device is directly installed between anchor cable lock and pallet, its screw thread claw is made to be embedded in the lock tube of anchor cable lock by tensioner, realize anchor cable fastening, during recovery, move back anchor sleeve pipe stretch into fluid pressure type constant-resistance device inside be connected with screw thread claw, anchor sleeve pipe is moved back by stretch-draw, drive screw thread claw to move, to realize the dismounting of screw thread claw, and then realize the recovery of this anchor cable permanent resistance install.
Its fluid pressure type constant-resistance device is made up of inner cylinder tube, outer cylinder and constant-resistance valve, inside and outside cylinder barrel close contact, before installation, inwardly, injection liquid force feed between outer cylinder, and blocked up by constant-resistance jam pot cover, during lane (tunnel) road surrouding rock deformation, hydraulic oil is overflowed by constant-resistance valve, to realize the constant of surrouding rock deformation process stream line supporting power.
Its screw thread claw with move back anchor sleeve pipe for being threaded, be external screw thread bottom screw thread claw, moving back anchor cannula tip is internal thread, during recovery, by knocking, shaking the form of moving back anchor sleeve pipe, screw thread claw is loosened, to realize the dismounting of screw thread claw; It moves back anchor sleeve bottom also can be provided with support structure, is moved back the form of anchor sleeve pipe by support, screw thread claw is loosened, realizes the dismounting of screw thread claw.
Beneficial effect of the present invention:
The fluid pressure type constant-resistance device of recyclable hydraulic anchor cable permanent resistance install is directly installed between anchor cable lock and pallet, install, easy and simple to handle, also possess following advantage simultaneously:
1. make cable bolting have good adaptive deformation ability, the ultimate extension length of fluid pressure type constant-resistance device determines the extended length of its cable bolting, fully and country rock compatible deformation, can avoid the problem that the country rock large deformation of lane (tunnel) road causes anchor cable disrumpent feelings.
2. adopt the constant pressure release principle of fluid pressure type constant-resistance device, in surrouding rock deformation, the Support Resistance making anchor cable provide continual and steady, ensure that cable bolting effect.
3. make cable bolting have stronger impact resistance, the instantaneous deformation that the constant pressure release principle of fluid pressure type constant-resistance device can make cable bolting adaptation impact loading produce, deformation of the surrounding rock in tunnel pressure is effectively discharged, guarantees that anchor cable is not disrumpent feelings under impact loading.
4. this device is furnished with anchor cable and moves back anchor structure, facilitates that this device is recyclable, recycling, and support cost is cheap.
