Abstract
The utility model relates to an underground anchor-rod tray cap rapid tightening device for a coal mine, which comprises a sleeve (3), wherein a sleeve head (1) is fixed on one end of the sleeve (3), and the other end of the sleeve (3) is connected with a rotating device. Compared with the prior art, the underground anchor-rod tray cap rapid tightening device has the rapidness: when using the torque wrench before, the operation personnel removes the torque wrench off after rotating the torque wrench for one time and sleeves the torque wrench on again or the operation personnel rotates while the torque wrench is fixed, so whether is in any of the two situations, the time and the labor are wasted, and particularly when the operation personnel rotates, the work of other people can be obstructed; high-efficiency: when using the rapid tightening device, the personnel is only required to stand at one side without rotating, so the time can be greatly saved, and the labor efficiency is improved. At the same time, the rapid tightening device also has the advantages of labor conservation, lower labor intensity and the like.
Description
Technical field
The quick fastener of underground mine use anchor pole dish cap belongs to supporting specific purpose tool under the coal mine.
Background technology
Along with the continuous exploitation of underground coal, the goaf area is increasing, and the crustal stress that is produced is also more and more obvious to the influence of producing, and guarantees to realize safety in production that for reducing this influence just supporting quality and the speed to the tunnel has had higher requirement.In the supporting process, the fastening employing of anchor pole dish cap be T font torque spanner, entangle the anchor pole cap when operating personnel use earlier and rotate to take off again and put rotation again, so repeatedly, perhaps entangle motionlessly, the operator rotates, not only time-consuming but also effort.
The utility model content
The technical problems to be solved in the utility model is: overcome the problem that prior art exists, design a kind of quick fastener of underground mine use anchor pole dish cap of simple in structure, time saving and energy saving, easy-to-operate.
The technical scheme that its technical problem that solves the utility model adopts is: the quick fastener of this underground mine use anchor pole dish cap is characterized in that: comprise an end fixed muffle head of sleeve, sleeve, the other end links to each other with rotary handle.
The length of sleeve can guarantee that operating personnel stand on the base plate and construct, and needn't climb to a higher point; The characteristics of whirligig are single load bearings, and make operator no longer take down sleeve one after another or personnel constantly rotate by rotary handle, have improved efficiency greatly.
Above sleeve, be welded with hook.After effect has been to use, quick fastener can be hung on the net, so just avoid throwing out without care leaving about, reach damage, promote carrying out production strictly in line with rules and regulations of down-hole instrument in group.
Compared with prior art, the beneficial effect that had of the quick fastener of the utility model underground mine use anchor pole dish cap is:
(1) generality: mine from not driving produce, production will be carried out supporting, supporting just can be used quick fastener;
(2) rapidity: when using torque spanner in the past, operating personnel one rotate to take off again to put rotation again, or entangle motionless personnel and rotate, and no matter which kind of situation all wastes time and energy very much, when especially personnel rotate, also might hinder other people to work;
(3) high efficiency: when using quick fastener, operating personnel only need stand in a side, needn't rotate, and have saved the time greatly, have improved efficiency; Meanwhile, also save manpower, reduced labour intensity.
Description of drawings
Fig. 1 and Fig. 2 are the quick fastener structural representations of the utility model underground mine use anchor pole dish cap, also are most preferred embodiments of the present utility model.
Wherein: 1 collet head, 2 hooks, 3 sleeves, 4 rotary handles, 5 pawl axis, 6 ratchets, 7 ratchets, 8 ratchet shafts.
The quick fastener of this underground mine use anchor pole dish cap, form by fixed part, whirligig and hanging portion three parts, fixed part is made up of the sleeve made from the steel pipe of the long φ 30mm of the supporting collet head 1 of anchor pole cap and 1.5m 3, collet head 1 is fixed on an end of sleeve 3, the other end of sleeve 3 links to each other with the ratchet shaft 8 of the rotary handle of rotating part 4. and the length of sleeve 3 can guarantee that operating personnel stand on the base plate and construct, and needn't climb to a higher point.
Whirligig is made up of rotary handle 4, ratchet 6, pawl axis 5, ratchet 7, ratchet shaft 8, ratchet 6 is installed on the rotary handle 4 by pawl axis 5, ratchet 7 is fixed on the ratchet shaft 8, ratchet shaft 8 is fixed on an end of rotary handle 4, ratchet 6 withstands on the tooth of ratchet 7 by the active force of spring, and ratchet shaft 8 is connected with an end of sleeve 3, during rotary handle 4 rotations, at effect bottom ratchet wheel axle 8 single load bearings of ratchet 6, drive sleeve 3 and rotate towards a direction.
The use of whirligig makes operator no longer take down sleeve 3 one after another or personnel constantly rotate, and has improved efficiency greatly.
The hanging portion is exactly two hooks 2 that are welded on the sleeve 3, after its effect has been to use, quick fastener can be hung in group on the net, has so just avoided throwing out without care leaving about, and reaches the damage to instrument, has promoted carrying out production strictly in line with rules and regulations of down-hole.
The course of work is as follows:
During the driving face permanent support, after rising an anchor pole, this quick fastener helped from the lane take off, entangle anchor pole cap to be tightened, hand steered a sleeve 3 with collet head 1, the another hand rotates rotary handle 4, reach the rules requirement up to anchor pole dish cap, take off quick fastener, carry out the fastening of next anchor pole dish cap, behind all fastening the finishing, it is hung go back to lane group.
The quick fastener of this underground mine use anchor pole dish cap is by down-hole real work checking, used this fastener after, support speed improves greatly, and has passed through the examination of departments such as engineering department.The fast development of fastener and successfully use and improved support speed and supporting quality has greatly reduced working strength of workers, has improved efficiency.
