Abstract
The invention discloses a lock retreat device of an anchor rope tensioning jack. A dismounting sleeve is arranged at the outer end of a lockset outer sleeve, the dismounting sleeve is a cylinder with conical counter bores, the diameter of the conical counter bores is slightly larger than the diameter of taper holes of the outer sleeve, round orifices are made on an end wall of the dismounting sleeve, the anchor rope penetrates the round orifices, observation holes are made on a circumferential wall. The tensioning jack pulls the anchor rope to move outwards to break away from the outer sleeve and the anchor rope. At the moment, lock core is in a free state, a screw driver or other rod-like tools are used to move the lock core through the observation holes, so that the lock core can be completely separated from the outer sleeve and the anchor rope, the lock device and a tray can be dismantled as long as the tensioning jack is taken off. In the invention, ordinary tensioning jacks applied to mineshafts are used for retreating locks, thus enjoying convenient and efficient operation and high working efficiency, saving time and reducing labor consumption; in addition, the device of the invention features simple and easy operation, ensured safety, no need of purchasing special anchor machine retreat, thus reducing equipment investment.
Description
Technical field
The present invention relates to a kind of mining equiment, be specifically related to use the locking device that moves back of stretch-draw jack dismounting anchor cable lockset.
Background technology
The colliery underworkings is along with coal face pushes ahead, and the cable bolting top board that use in two tunnels must be pulled down at any time, otherwise, assemble gas in the discarded tunnel (being commonly called as the old man), for underground work brings serious potential safety hazard.Because top board and pallet are fixed on the anchor cable by lockset, adopt commercial special use to move back windlass at present and remove, this windlass price of moving back is about 3000 yuan, and not only the price height is operated also inconvenience, and it is time-consuming to require great effort, and the application life of moving back windlass is not long yet, the maintenance cost height.
Summary of the invention
In order to address the above problem, the invention provides a kind of cable stretching jack releasing device, the dismounting cover is set in the outer end of lockset overcoat, described dismounting cover is the cylinder with conical counterbore, its circular cone counterbore straight through being slightly larger than the straight warp of overcoat taper hole, dismounting cover end wall is made circular hole, and anchor cable passes from this circular hole, makes peep hole on the circumferential wall.Move outward with stretch-draw jack pulling anchor cable, make lock core break away from overcoat, realize moving back lock
The present invention is achieved through the following technical solutions: a kind of cable stretching jack releasing device comprises the anchor cable that is fixed in the cinclides of tunnel, the top board of being close to wall and pallet, is installed in the lockset of pallet outer end; Described lockset comprises overcoat and is inserted into lock core in the overcoat; Described overcoat is a cylinder, and the center makes conical bore, makes the tooth that goes in ring on the circular cone hole wall; Described lock core is three, and its cylindrical is fan-shaped wedge, and the gradient of outer conical surface equates with the gradient of overcoat taper hole, makes the tooth that goes in ring on the conical surface; When described lock core is pressed into overcoat anchor cable is locked, it is characterized in that: the dismounting cover is set in the outer end of overcoat; Described dismounting cover is the cylinder with conical counterbore, its circular cone counterbore directly through being slightly larger than the straight warp of overcoat taper hole, dismounting cover end wall is made circular hole, anchor cable passes from this circular hole.
Described dismounting puts the making peep hole.
Good effect of the present invention is:
1, utilizes mine stretch-draw jack commonly used to move back lock, need not purchase the special windlass that moves back, reduce equipment investment.
2, convenient and swift, save time, high efficiency reduces workman's physical demands
3, simple to operation, safety is guaranteed;
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Fig. 1 is a structural representation of the present invention.
Among the figure: 1, anchor cable, 2, wall, 3, pallet, 4, overcoat, 5, lock core, 6, the dismounting cover, 6-1, peep hole, 7, the stretch-draw jack, 8, top board.
The specific embodiment
As shown in drawings: when moving back lock, to dismantle cover 6 is sleeved on the anchor cable 1, the end of stretch-draw jack 7 is held out against the end of dismounting cover 6, its dop tightly clamps anchor cable 1, the operating grip of starting stretch-draw jack, powerful pulling anchor cable 1 outer moving, anchor cable drives lock core 5 outer moving, and breaks away from overcoat 4 and anchor cable 1, at this moment, 5 one-tenth free states of lock core are stirred lock core 5 with screwdriver or other bar class instrument again from peep hole (6-1), make it to break away from fully with overcoat 4, anchor cable 1, take off stretch-draw jack 7, lockset and pallet 3 just can be pulled down, and take off top board 8, move back anchor work and finish.Convenient and swift, save time, high efficiency reduces workman's physical demands, and is simple to operation, and safety is guaranteed.Utilize mine stretch-draw jack commonly used to move back lock, need not purchase the special windlass that moves back, reduce equipment investment.
