When the cylinder 5 normally operates, the moving rod 6 generates a certain pulling force on the pulling rope 21, the pulling rope 21 is wound on the rotating wheel 22 for one turn, so that the rotating wheel 22 moves upwards for a certain distance, the rotating wheel 22 drives the rotating shaft 23 to move upwards, the rotating shaft 23 drives the sleeve ring 26 to move upwards, the sleeve ring 26 enables the second spring 25 to be compressed, when the cylinder 5 is controlled, the pulling force is kept constant, so that the compression length of the second spring 25 is kept fixed, the rotating shaft 23 is kept fixed, the rotating wheel 22 is kept fixed, so that the pulling rope 21 pulls the rotating wheel 22 to rotate, at the same time, the rotating wheel 22 is kept rotating at a certain height, here, the rotating shaft 23 moves upwards, the rotating ring 27 is driven to move upwards, the rotating ring 27 drives the rotating rod 28 to move upwards, at this time, the rotating rod 28 does not collide with the baffle 29, when power is cut off, the cylinder 5 is not controlled, the gravity of, at this moment, stay cord 21 will drive runner 22 swivelling joint again and move, thereby make runner 28 and baffle 29 support and lean on, runner 22 just can't rotate this moment, a part pulling force will be offset to stay cord 21 and runner 22's frictional force, make the downward impact force of drill bit 7 reduce, thereby make centre gripping subassembly can be better carry drill bit 7, realize better protection to the device, here perforating device adopts unmanned automatic mode of punching to punch, when not considering the outage, cause the injury to the people, only when to the outage, cylinder 5 is unattended, drill bit 7 collides with the device of below, cause the device damage of drill bit 7 below and the damage of drill bit 7.
The device punches through the mechanism of punching, when the outage suddenly, carries out both sides centre gripping and compresses tightly to drill bit 7 through spacing subassembly drive clamping assembly, avoids the continuation removal of drill bit 7, cushions drill bit 7's overdraft through buffer gear, avoids drill bit 7 impact force to slide in the clamping assembly when too big, realizes better centre gripping effect to the better continuation removal of having avoided drill bit 7 has realized the protection to the device.
Compared with the prior art, this perforating device with power-off protection function, realize punching through the mechanism of punching, realize the protection to the device through protection mechanism, compare with current perforating device, this perforating device is through the pure mechanical linkage between mechanism and the protection mechanism of punching, all carry out real time monitoring to the operation of cylinder 5 each time, and avoided the use of other electronic component, the stability and the life of protection mechanism have been improved, compare with current protection mechanism, this protection mechanism realizes the centre gripping in three position to drill bit 7 through clamp splice 9 and briquetting 16, realize better tight effect of clamp, and cushion drill bit 7's overdraft through buffering the subassembly, it is too big to avoid the impact force, cause the slip of drill bit 7 in the centre gripping subassembly, the tight effect of clamp has been improved.
In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
