Description
Technical field
The utility model relates to a kind of drilling aid, especially a kind of boring swelling device.
Background technology
At present, in mine engineering construction drill process, need sleeve pipe to be fixed on crag, the method generally adopted is that boring is installed rivet or adopted chock embedded fixing on crag, or adopts concrete perfusion to be fixed.Said method both bothered, and turn increased the labour intensity of workman.When dismantling sleeve pipe, need to destroy crag just can remove.Therefore, need to design one and namely can conveniently install, boring swelling device that again can be for convenience detach.
utility model content
It is not quick detachable that goal of the invention of the present utility model is to overcome current sleeve pipe, installs trouble, the defect that labour intensity is large, realizes dismounting quick, facilitate easy-to-use boring swelling device.
For achieving the above object, the technical solution of the utility model is: a kind of boring swelling device, comprises sleeve pipe, described sleeve outer is provided with step, and left part external diameter is greater than right part external diameter, sleeve pipe left part external diameter is provided with the conical surface, and the external diameter of right part right-hand member has external screw thread; Also comprise the ringfeder coaxial with described sleeve pipe, advance retracting mechanism and top cover, described ringfeder is the hollow tubular structures of uniform groove on left part outer wall, and ringfeder left part inwall is provided with the inner conical surface mated with sleeve pipe male cone (strobilus masculinus), inwall on the right side of ringfeder inner conical surface is provided with positive stop lug boss, and on the right side of positive stop lug boss, ringfeder end is provided with step groove; Top cover left part is provided with step groove, and right part inwall is provided with the internal thread mated with the external screw thread of sleeve pipe right-hand member; Retracting mechanism is advanced to be fixedly installed between ringfeder and top cover.
Described propelling retracting mechanism comprises left snap ring, right snap ring and draw ring, draw ring two ends are provided with step, draw ring is sleeved on sleeve pipe and draw ring two ends step and is arranged in the step groove of ringfeder and top cover respectively, left snap ring and right snap ring are arranged on the periphery between ringfeder and the outer wall of top cover in the middle part of draw ring, left snap ring is connected by securing member with ringfeder, and right snap ring is connected by securing member with top cover.
The course of work of boring swelling device of the present utility model: whole swelling device is placed in crag, then rotate top cover and start precession, ringfeder is by the axial relative motion along sleeve pipe, ringfeder has the outer wall of conical surface end to start to contact with crag under the effect of sleeve pipe, and finally realize tensioner, whole swelling device is fixed on crag; When dismantling this swelling device, only top cover need be rotated round about, pull ringfeder to carry out relative motion along the axis of sleeve pipe by draw ring, ringfeder has the outer wall of conical surface end and crag to reduce gradually to contact, and finally lose tensioner effect, then whole swelling device is taken out from crag.
The beneficial effect of boring swelling device of the present utility model:
1. boring swelling device of the present utility model, structure is simple, is convenient to realize sleeve fixing on crag, ringfeder is the hollow tubular structures of uniform groove on left part outer wall, ringfeder tensioner heel crag close contact, installs reliable, can meet various drilling construction requirement.
2. boring swelling device of the present utility model, only need clockwise or counterclockwise rotation top cover just can realize swelling device to mount and dismount rapidly, and destruction can not be produced to associated mechanical element, simple to operate, can operating efficiency be improved, reduce labor strength.
