Detailed Description
Referring now to the drawings, the following is described, in connection with specific embodiments: the invention relates to a high-altitude long-distance pneumatic boosting device for a blasting broken jacking cylinder-shaped explosive roll, which comprises a fixing frame 1, a gun rod frame 2, a driven sprocket 3, a driving sprocket 4, a pushing platform 6 and a chain 8. The top of mount 1 is articulated through the articulated elements has big gun pole frame 2, the top of big gun pole frame 2 is provided with driven sprocket 3 through the mounting, and its bottom is provided with drive sprocket 4 through the mounting, drive sprocket 4 passes through the connecting piece and connects pneumatic motor 5, pneumatic motor 5 mounting is fixed on big gun pole frame 2. The top of the gun rod frame 2 is also provided with a guide frame 9 of a gun rod 11 through a connecting piece, the guide frame 9 is provided with a clamping device 10 capable of fixing the gun rod 11, and the specific form of the clamping device 10 can refer to the clamping device with a self-locking function. The gun rod frame 2 is provided with a pushing platform 6 matched with the guide frame 9, the pushing platform 6 is provided with a pushing plate 7, one end of a chain 8 is connected with the top end of the pushing platform 6, and the other end of the chain is connected with the bottom end of the pushing platform 6 by sequentially bypassing the driven sprocket 3 and the driving sprocket 4. The bottom of big gun pole frame 2 is connected with adjusting screw 12, the bottom of mount 1 articulates through the articulated elements has with adjusting screw 12 matched with connecting pipe 13, adjusting screw 12's top articulates through the articulated elements with big gun pole frame 2, and its bottom activity passes connecting pipe 13, the spiro union has positioning nut 14 on the adjusting screw 12 of connecting pipe 13 both ends department.
The application principle of the invention is as follows: this pusher switch on, the staff opens the clamp 10, wears to locate in the leading truck 9 with the top of big gun pole 11, and the bottom of big gun pole 11 then supports the push pedal 7 on the promotion platform 6. The worker unscrews the positioning nut 14, and can adjust the inclination of the gun rod frame 2 through the adjusting screw 12 so as to lead the gun rod 11 to be aligned with the broken top hole, and the positioning nut 14 is screwed after the position is determined. The staff starts the pneumatic motor 5, and the pneumatic motor 5 drives the driving sprocket 4 to rotate to upwards pull the push platform 6 through the chain 8, can push the big gun pole 11 through push pedal 7 when push platform 6 moves upwards. When the gun rod 11 penetrates into the broken top hole, namely, the pushing platform 6 moves to the top of the gun rod frame 2, the pneumatic motor 5 is turned off, and the gun rod 11 is fixed through the clamping device 10. The worker reversely operates the pneumatic motor 5 to reset the pushing platform 6, installs the gun rod 11 again, and continues pushing the gun rod 11 according to the operation until the gun rod 11 pushes the broken explosive to the required position.
