Abstract
The utility model provides an anchor pole remover directing at the industrial problems that massive waste of production tools is caused because a large number of anchor poles existing in coal mine production can not be recovered after utilization for reuse as the anchor poles are fixed on the wall of a mine, and that cracked anchor poles are very easy to cause damage to coal cutters and crushers during the production process. The anchor pole remover comprises a coring bit (1), more than one auger stem (2), and a connector (3) and is powered by a hand-held assistant anchor drilling machine. The anchor poles embedded in the wall of tunnels of the mine can be completely taken out. The anchor pole remover is capable of solving the problem that the anchor poles can be used for once only, reducing the production cost, and moreover, protecting the safety production by coal mining equipment.
Description
Technical field
The utility model relates to a kind of coal mining equipment, is specifically related to a kind of anchoring-bolt extractor for reclaiming the mine roadway support anchor pole.
Technical background
Along with development and the extensive use of China's coal-mine underground anchor link network support technology, the mine roadway support anchor pole uses under coal mine in a large number, and the safety in production in colliery has obtained further assurance.But use in a large number anchor pole also to bring suitable inconvenience in the mining process of colliery: at first, existing anchor pole namely is being fixed on after the use on the mine borehole wall, can't reclaim again and utilize, and causes a large amount of wastes of the tool of production; Secondly, present most collieries are directly to carry out coal cutting in mining process, also cutting, interrupting anchor pole simultaneously in the time of will causing like this coal-winning machine to carry out coal cutting, and the cutter head of coal-winning machine damages very easily in this course; Again, the anchor pole and the coal that are interrupted enter crushing engine together, will further damage crushing engine.
The utility model content
For the problems referred to above that exist in the coal production; the utility model provides a kind of anchoring-bolt extractor, the anchor pole in the mine laneway intactly can be taken out, and has solved the problem that anchor pole can only single uses; save production cost, and can play certain protective effect to the safety in production of coal excavation apparatus.
Technical solution adopted in the utility model is as follows:
1, a kind of anchoring-bolt extractor is comprised of coring bit 1, the auger stem 2 more than, connector 3;
2, described anchoring-bolt extractor, the length of auger stem 2 are 60～100 centimetres;
3, between the described anchoring-bolt extractor, auger stem 2 and coring bit 1 for being threaded; For being threaded, the radial sidewalls in the two junction is provided with locking screw holes between described auger stem 2 and the connector 3, cooperates in the locking screw holes to be provided with screw 6;
4, described anchoring-bolt extractor is comprised of coring bit 1, two auger stems 2, connectors 3, and two auger stems 2 connect successively by screw thread, and the radial sidewalls in the two junction is provided with locking screw holes, cooperates in the locking screw holes to be provided with screw 6.
The good effect that the utility model has has:
1, this anchoring-bolt extractor is simple in structure, convenient operation;
2, adopting behind this anchoring-bolt extractor can complete recovery anchor pole, has improved the recycling rate of waterused of anchor pole, has saved labor and materials, has reduced cost of production;
3, solved the damage problem that broken anchor pole causes coal-winning machine cutter head, crushing engine and conveyer belt in the mining process.
Description of drawings
Fig. 1 is front view of the present utility model.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is the schematic diagram that the utility model connects an above auger stem.
Sequence number is followed successively by among the upper figure: coring bit 1, auger stem 2, connector 3, helix 4, the hole 5 of producing coal, screw 6.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and implementation.
Embodiment 1:
Referring to Fig. 1, apparatus structure of the present utility model is comprised of coring bit 1, auger stem 2 and connector 3; Wherein coring bit 1 is the cone of hollow, and its smaller diameter end is connecting an end of auger stem 2, and described auger stem 2 is tubulose; Auger stem 2 external surfaces are provided with the helix 4 of one projection; The footpath of auger stem 2 makes progress and uniformly offers the hole 5 of producing coal, and adjacent spacing of producing coal between the hole 5 equates, the other end of auger stem 2 is connecting connector 3; Connector 3 is cylinder, and connector 3 middle parts radially both sides are arranged with respectively the cylinder projection.
Between described auger stem 2 and the coring bit 1 for being threaded; For being threaded, the radial sidewalls in the two junction is provided with locking screw holes between described auger stem 2 and the connector 3, cooperates in the locking screw holes to be provided with screw 6.
During use, help the anchor rig to be connected and to be fixed with it by the projection on the connector 3 with the as above connector 3 of device hand-held; With starting hand-held side anchor rig behind the anchor pole in the coring bit 1 aligning borehole wall, coring bit 1 is squeezed into the borehole wall together with auger stem 2, so that anchor pole is wrapped in the tube chamber of auger stem 2 fully subsequently; Make again subsequently the anchor rig reverse rotation of hand-held side, so that coring bit 1, auger stem 2 and anchor pole together rotate the borehole wall.
Embodiment 2:
Referring to Fig. 3, with coring bit 1, auger stem 2, a connector 3 be connected with hand-held the anchor rig as described in Example 1 mode connect and fix.During use, start first hand-held side anchor rig, with coring bit 1 together with accurate anchor pole on 2 pairs of boreholes wall of auger stem and squeeze in the borehole wall; Then close hand-held side anchor rig, connector 3 and auger stem 2 are disconnected, newly get an auger stem 2 and be connected with the auger stem 2 of having squeezed into before the borehole wall, again connector 3 is connected with the auger stem 2 of newly getting; Open again subsequently hand-held side anchor rig switch this device is continued to screw in the borehole wall, until reach desired depth; At last, more as described in Example 1 method oppositely screw out coring bit 1, auger stem 2 and anchor pole.
When usually not using, coring bit 1, auger stem 2, connector 3 removable rear respectively collection keepings.
