Abstract
The utility model discloses a knocking's device in stone drifting, including two sleeve (1) that the suit is in the same place, inlayer sleeve (1 -b) one end is sled head (2), and outer sleeve (1 -a) one end is equipped with stop screw (3), and cover rubber sleeve (4) is gone up to outer sleeve (1 -a). The utility model discloses can nimble adjusting device length, the at utmost reduces because of prizing the impact that the float stone produced to both hands, to the effective sled of safety down the float stone, shell the layer and have important meaning.
Description
Technical field
The utility model belongs to engineering practice field, relates to a kind of device of tapping, the device of particularly tapping in a kind of stone drifting.
Background technology
In hard rock tunnel (tunnel), the normal drilling and blasting method that adopts excavates.Before production operation after explosion starts, need to knock roadway, face roof and lateral wall with crowbar, drill rod or pick etc., find float stone, delamination according to the sound sent, thus safety is prized down in time, ensured the safety of operating personnel and normally carrying out of production operation.At present, crowbar used in the process of tapping in engineering mostly is the non-telescoping iron structure of welding.The situations such as in use ubiquity effort, inefficiency.
Summary of the invention
The purpose of this utility model is the shortcoming such as use inconvenience, inefficiency of tapping crowbar in process for existing stone drifting, provides a kind of laborsaving telescopic device of tapping.
The purpose of this utility model realizes by following technical proposal:
A device of tapping in stone drifting, is characterized in that two sleeves be set in together, and inner layer sleeve one end is pry head, and outer layer sleeve one end is provided with stop screw, and outer layer sleeve overlaps rubber sleeve.
The device of tapping in above-mentioned a kind of stone drifting, is characterized in that, two described sleeves be set in together are made up of outer layer sleeve and inner layer sleeve.
The device of tapping in above-mentioned a kind of stone drifting, is characterized in that, described two the sleeve materials be set in together are iron and steel, and radius is 15mm ~ 20mm.
The device of tapping in above-mentioned a kind of stone drifting, is characterized in that, outer layer sleeve one end is provided with stop screw, and stretching between two sleeve pipes is controlled by stop screw.
The device of tapping in above-mentioned a kind of stone drifting, is characterized in that, one end of described inner layer sleeve is pry head, and be Curved Flat hook structure, both adopt welding manner to connect.
The device of tapping in above-mentioned a kind of stone drifting, is characterized in that, described outer layer sleeve overlaps rubber sleeve, can play cushioning effect, reduce the impact force to both hands under prizing when float stone, delamination.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1, sleeve; 1-a, outer layer sleeve; 1-b, inner layer sleeve; 2, pry head; 3, stop screw; 4, rubber sleeve.
Detailed description of the invention
Be below specific embodiment of the utility model, by reference to the accompanying drawings, the technical solution of the utility model be further described, but the utility model is not limited to these embodiments.
The device of tapping in a kind of stone drifting in the present embodiment is by two sleeves be set in together 1, and pry head 2, stop screw 3, rubber sleeve 4 forms.
Outer layer sleeve 1-a is made up of carbon constructional quality steel C35, and length is 1500mm, and radius is 15mm, inner layer sleeve 1-b is made up of carbon constructional quality steel C35 equally, and length is 900mm, and radius is 13mm, both are set in together, and the length adjusting range of sleeve 1 is 1500mm ~ 2100mm.Outer layer sleeve 1-a right-hand member limited location screw 3, controls the telescopic of sleeve 1.Outer layer sleeve 1-a overlaps rubber sleeve 4, and rubber sleeve 4 is made up of rubber, and length is 1000mm, and thickness is 2mm.
Inner layer sleeve 1-b one end is connected with pry head 2, and pry head 2 is Curved Flat hook structure, is made up of high strength steel iron material, and lateral length is 200mm, and inner layer sleeve 1-b adopts welding manner to be connected with pry head 2.
During use, first, staff can carry out the suitable length of regulating sleeve 1 to by stop screw according to actual needs; Secondly, the both hands outer layer sleeve 1-a that holds with a firm grip carries out knocking face roof and lateral wall, and find float stone, delamination according to the sound sent, thus prized down with pry head 4 is safe in time, rubber sleeve 4 cushioning effects, reduce the impact force produced because prizing float stone; Finally, after finishing using, sleeve 1 is contracted to shortest length, device is placed in article placement rack.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
