Description

Hydraulic locking drill rod lifter for anchor rod machine

Technical Field

The utility model relates to an anchor rod machine especially relates to a bore bit ware is held up in hydraulic locking for anchor rod machine.

Background

At present, most of the prior drill rod supporters on the anchor rod machine at home adopt two semicircular clamping blocks, the two semicircular clamping blocks are closed and locked by bolts or bolts to form a circular guide hole, and when the anchor rod machine drills an anchor rod hole or an anchor cable hole, the anchor rod passes through the circular guide hole to play a role in guiding the anchor rod. When annotating the stock behind the drilling, need the manual work to separate two semicircular clamp blocks from the guiding hole to stock or anchor rope rear portion's backing plate passes through, locks stock or anchor rope operation again, owing to take manual operation, it is inconvenient, work efficiency is low, and when carrying out the higher stock locking in tunnel top or position, need carry out the operation with the help of auxiliary device more, this kind of mode not only intensity of labour is big, still has the potential safety hazard, and work efficiency is low.

In addition, few anchor rod machines are arranged in China, the guide hole in the drill rod lifter is made into an integral body which cannot be disassembled, when an anchor rod or an anchor cable hole is drilled, the anchor rod machine needs to be moved back to the rear end of the guide rail (namely, the position farthest away from the drill rod lifter), the anchor rod is firstly inserted into the guide hole, then the tail part of the anchor rod is inserted into the anchor rod machine for fastening, and then the operation of drilling the anchor rod hole or the anchor cable hole is carried out. When the anchor rod is injected, the anchor rod machine is required to be withdrawn and then the anchor rod or the anchor cable is manually locked, so that the method is inconvenient to operate, low in efficiency, time-consuming and labor-consuming, and also has potential safety hazards.

SUMMERY OF THE UTILITY MODEL

The operation that exists to the present rockbolt machine is held up the borer ware inconvenient, work efficiency is low and there is the potential safety hazard scheduling problem, the utility model provides an automatic hydraulic pressure locking who locks and loosen holds up the borer ware.

The to-be-solved technical problem of the utility model adopts the technical scheme that: a hydraulic locking drill rod lifter for a roof bolter is assembled at the front end of a guide rail of the roof bolter and comprises a connecting seat, wherein one end of the connecting seat is connected with the guide rail, a vice oil cylinder with a piston rod moving up and down is arranged on the end surface of the connecting seat, the outer end of the piston rod is movably connected with one end of a hinge plate I and one end of a hinge plate II, a pin shaft II is movably arranged on the connecting seat and movably connected with the lower ends of the hinge seat I and the hinge seat II which are arranged on two sides of the connecting seat, the other ends of the hinge plate I and the hinge plate II are respectively movably connected with the middle parts of the hinge seat I and the hinge seat II through the pin shaft I, the upper ends of the hinge seat I and the hinge seat II are cantilever-shaped and are relatively provided with a drill rod supporting sleeve I and a drill rod supporting sleeve II, and guide holes which enable a roof bolter to.

The utility model discloses make the free bearing I that links to each other with the piston rod and free bearing II up-and-down motion with the vice hydro-cylinder to drive free bearing I that links to each other with free bearing I and free bearing II and respectively synchronous relative horizontal hunting around its lower extreme, thereby make free bearing I and free bearing II move about the synchronous relative side-to-side motion of the drill rod cover of upper end, when synchronous relative inward movement, the drill rod cover I folds with the drill rod cover II, form a guiding hole that can make the stock make a round trip to slip, the stock is normal work when guaranteeing the stock machine bores anchor rod hole or anchor rope hole; when the synchronous relative outward motion, hold up drill sleeve I and hold up drill sleeve II and open, form an opening that can make the backing plate of stock rear end pass through, ensure to lock stock or anchor rope operation in time.

The utility model discloses utilize lever principle, when guaranteeing original direction, support the function basis, its simple structure, convenient operation adds and installs with low costs on the stock machine additional, has inherited in the past on the direction of holding up the borer ware, the function basis of supporting in addition, will hold up drill sleeve separable size and increase to the accessible backing plate size, has improved the passability of backing plate greatly, has reduced intensity of labour, when having improved work efficiency, has also stopped most potential safety hazard.
