Abstract
The utility model discloses a wind-driven spiral anchor rod recovery device and relates to the field of anchor rod recovery tools. The wind-driven spiral anchor rod recovery device solves the problems that at present the taking out of an anchor rod which is used for supporting a mine tunnel is labor-consuming and time-consuming and the like. The wind-driven spiral anchor rod recovery device comprises a wind-driven drilling machine and a drilling machine connecting sleeve. The wind-driven spiral anchor rod recovery device is provided with a recovery spiral casing and a coring bit, wherein the recovery spiral casing is connected with the wind-driven drilling machine through the drilling machine connecting sleeve, and the coring bit is fixed with the recovery spiral casing in a welding mode. The recovery spiral casing is a long pipe shaped hollow body, and drill rod threads are arranged on the outer wall of the recovery spiral casing. The wind-driven spiral anchor rod recovery device is simple in structure, easy to manufacture and convenient to use.
Description
Technical field
The utility model relates to a kind of anchor recovering instrument, is specifically related to a kind of pneumatic screw type anchor rod recovery device.
Background technology
General needs use spiral anchoring-bolt as reinforcement material in the support technology that mine laneway adopts, but back production often can be carried out to the tunnel in process of production in the colliery, be difficult to take out as the anchor pole of reinforcing usefulness, the reinforcing anchor pole that this retains on the one hand can damage the cutting coal machine cutter, brings serious potential safety hazard if then easily cause gas explosion accident after the spark that produces after while anchor pole and the percussion of coal cutting cutter meets with local accumulation gas to downhole production; To reinforce on the other hand to stay with anchor pole and then be not only a kind of waste to resource in the wall, and the reinforcing anchor pole of leaving over does not consist of greatly harm so that top board is not caving the large-area outstanding top of easy formation to the safety in production of work plane.
The utility model content
The purpose of this utility model is in order to overcome deficiency of the prior art, a kind of pneumatic screw type anchor rod recovery device simple in structure, easy to manufacture and easy to use to be provided.
For achieving the above object, the utility model provides a kind of pneumatic screw type anchor rod recovery device to comprise pneumatic drilling machine and rig adapter sleeve, described pneumatic screw type anchor rod recovery device is provided with and reclaims screw shell and coring bit, reclaim screw shell and be connected with pneumatic drilling machine by the rig adapter sleeve, coring bit is welded and fixed with the recovery screw shell; The elongated tubular body that described recovery screw shell is hollow, the outer wall that reclaims screw shell is provided with drill rod thread.
The length of described recovery screw shell is greater than the length of spiral anchoring-bolt.
The beneficial effects of the utility model: pneumatic screw type anchor rod recovery device of the present utility model is simple in structure, easy to manufacture, and cost is low; Downhole operations librarian use pneumatic screw type anchor rod recovery device in colliery can take out the spiral anchoring-bolt in the wall like a cork, and is easy and simple to handle, reduced widely operating personnel's labour intensity, also greatly improved production efficiency.
Below in conjunction with accompanying drawing pneumatic screw type anchor rod recovery device of the present utility model is described further.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the utility model reclaims the screw shell cut-away view.
Among the figure: 1, pneumatic drilling machine, 2, the rig adapter sleeve, 3, reclaim screw shell, 4, coring bit, 5, drill rod thread.
The specific embodiment
As shown in Figure 1, the pneumatic screw type anchor rod recovery device of present embodiment comprises pneumatic drilling machine 1 and rig adapter sleeve 2.Pneumatic screw type anchor rod recovery device is provided with and reclaims screw shell 3 and coring bit 4, reclaims screw shell 3 and is connected with pneumatic drilling machine 1 by rig adapter sleeve 2, and coring bit 4 is welded and fixed with recovery screw shell 3.As shown in Figure 2, reclaiming screw shell 3 is the elongated tubular body of hollow, and the outer wall that reclaims screw shell 3 is provided with drill rod thread 5.Reclaim the length of screw shell 3 greater than the length of spiral anchoring-bolt.
Remove first hold-down nut and steel plate on the anchor pole in the wall, then the coring bit of pneumatic screw type anchor rod recovery device of the present utility model is enclosed within the end of anchor pole and along anchor pole to wall in bore, when coring bit get into square when bottom anchor pole then Automatic-falling get off, thereby can take out like a cork anchor pole.
Claims (2)
