Abstract
The utility model relates to a device for the coal mines, particularly to a retrieving device for the roof bolt, solved the problem that the coal mining machine's damage limits the coal mining speed and reduces the work efficiency because of the existence of the roof bolt when the existing coal mining machine mining, the utility model comprises a drilling apparatus and a hollow drill pipe which is connected with the drilling apparatus, and the inside diameter of the hollow drill pipe is larger than the roof bolt, one end of the hollow drill pipe is arranged a sleeve matched and connected with the power head of the drilling apparatus, broaches are distributed all around the other end, a plurality of longitudinal ribs distributed in spiral are arranged on the extine of the hollow drill pipe, the drilling apparatus adopts a MQ50 type hand held roof bolt drilling machine. Compared with the existing technology, the utility model plays the action of retrieving the roof bolt in advance, eliminating various adverse effects caused by that the roller of the coal mining machine cuts the roof bolt, enhanced the work efficiency for the coal mining, the utility has simple structure, is light, convenient to process, operate and maintain.
Description
Technical field
The utility model relates to coal mine equipment, is specially a kind of group anchor pole retracting device.
Background technology
Known, most of collieries are when excavation, and are stable for guaranteeing excavated surface, the protection personal safety, and bolt support is adopted in the tunnel more than 98%, and stope two crossheading coals group all adopts anchor metal to carry out supporting basically.Just because of this, give and bring inconvenience when mining, because when work plane is pushed ahead, according to the coal mining operational sequence, coal-winning machine will cut sth. askew into cutter, do breach, but because the existence of group's anchor pole will help anchor pole to be involved in cylinder when being easy to cause the coal-winning machine operation, gently then damage pick, heavy then limited the cylinder operation, limited coal mining speed, reduced operating efficiency, therefore, be very important to helping anchor pole to reclaim.
Summary of the invention
The utility model owing to the existence of helping anchor pole damages coal-winning machine, limited coal mining speed, reduces problems such as operating efficiency in order to solve existing coal-winning machine when mining, and a kind of group anchor pole retracting device is provided.
The utility model is to adopt following technical scheme to realize: group's anchor pole retracting device, comprise drilling tool and be connected with it and internal diameter greater than the hollow drill of group's anchor pole, hollow drill one end is provided with and drilling tool unit head coupling and interconnective sleeve pipe, be distributed with drill bit around the hollow drill other end, the length of described hollow drill is determined according to group's rock-bolt length.During use, hollow drill is enclosed within outside group's anchor pole, creeps under the effect of drilling tool, outside hollow drill was enclosed within group's anchor pole fully, the cinder in the drilling process was discharged by the drilling rod hollow parts, thereby easily will help the whole taking-up of anchor pole.
Described hollow drill outer wall is provided with some the vertical ribs of shape distribution in the shape of a spiral, and it act as further expansion boring internal diameter, simultaneously can the row's of assisting cinder.
Described drilling tool adopts MQS50 type hand-held group armature boring machine.
Compared with prior art, the utility model has played the effect of reclaiming group's anchor pole in advance, eliminate the various adverse consequences that cause because of coal mining machine roller cutting anchor pole, improved the operating efficiency of mining, processing simple in structure, light, easy, and be convenient to operation and maintenance, the anchor pole that reclaims with this device can reuse once more, calculates by 1 year back production ten thousand metres, after group's anchor pole is recycled, 1 year cost-saved about 750,000 yuan, have certain popularization value and use value.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Among the figure: 1-hollow drill 2-sleeve pipe 3-drill bit 4-indulges rib
The specific embodiment
Group's anchor pole retracting device, comprise drilling tool and be connected with it and internal diameter greater than the hollow drill 1 of group's anchor pole, its internal diameter generally is not less than 5cm, hollow drill 1 one ends are provided with and drilling tool unit head coupling and interconnective sleeve pipe 2, be distributed with alloy bit 3 around hollow drill 1 other end, and can guarantee that group's anchor pole passes through smoothly; Hollow drill 1 outer wall is provided with some the vertical ribs 4 of shape distribution in the shape of a spiral, adopts the 6mm reinforcement fabrication; Drilling tool adopts MQS50 type hand-held group armature boring machine, is existing known products.
During concrete enforcement, at first will help anchor nut and pad to unload down, because when hollow drill is longer, in boring procedure, be easy to double swerve, locate inaccurate, all will be enclosed within outside group's anchor pole earlier than short hollow drill (such as 0.8 meter), starting group's armature boring machine creeps into, when creeping into 0.7-0.8 rice, 0.8 meter hollow drill is taken out and dismounting, will be installed in the auger front end by sleeve pipe than long hollow drill (such as 1.7 meters) then, continue to creep into, outside hollow drill was enclosed within group's anchor pole fully, the cinder in the drilling process was discharged by drilling rod hollow parts and the outer vertical rib of hollow drill, thereby had finished the recovery of group's anchor pole.
Claims (3)
1, a kind of group anchor pole retracting device, it is characterized in that comprising drilling tool and be connected with it and internal diameter greater than the hollow drill (1) of group's anchor pole, hollow drill (1) one end is provided with and drilling tool unit head coupling and interconnective sleeve pipe (2), is distributed with drill bit (3) around hollow drill (1) other end.
2, group according to claim 1 anchor pole retracting device is characterized in that described hollow drill (1) outer wall is provided with some the vertical ribs (4) that distribute of shape in the shape of a spiral.
