will the utility model discloses the upper and lower position that corresponds when being in the user state defines for top and below in proper order.

As shown in fig. 1-3, the utility model provides a powerful stable crushing equipment, including controller, leading truck 1 and hammer block 2, seted up the inner chamber 3 that link up the bottom in leading truck 1, in this embodiment, leading truck 1 is square tubular structure, and four edges of leading truck 1 are provided with reinforcement rib 4, and hammer block 2 passes through bearing 5 and links to each other with 4 inner walls of reinforcement rib. A traction device is fixed on the top wall of the guide frame 1 above the hammer block 2, the traction device is a hydraulic cylinder 6 in the embodiment, and the hydraulic cylinder 6 is electrically connected with the controller. The end of the telescopic rod of the hydraulic cylinder 6 is hinged with two lifting hooks 7 which are overlapped front and back, the directions of the two lifting hooks 7 are opposite, the center of the top of the hammer block 2 is provided with a pin shaft 8 which is vertical to the direction of the lifting hooks 7, the top of the hammer block 2 is provided with a pit 9 which is matched with the position of the lifting hooks 7, and the lifting hooks 7 can be ensured to hook the pin shaft 8.

The inner wall of the guide frame 1 above the lifting hook 7 is provided with a plurality of groups of limiting devices, each group of limiting devices comprises two limiting blocks 12 corresponding to the positions of the lifting hook 7, and the lifting hook 7 can move upwards along with the hydraulic cylinder 6 to touch the limiting blocks 12 to turn over and break away from the pin shaft 8. Every stopper 12 all with telescoping device 13 fixed connection, telescoping device 13 can drive stopper 12 and break away from inner chamber 3, does not hinder the up-and-down motion of hammer block 2, telescoping device 13 can be hydraulic telescoping rod or electric telescopic handle, and telescoping device 13 is connected with the controller electricity respectively. The outside cover of round pin axle 8 is equipped with rotatable sleeve 10, and lifting hook 7 is provided with gyro wheel 11 towards the one end of stopper 12, and sleeve 10 and gyro wheel 11 can reduce the frictional force that lifting hook 7 and round pin axle 8 received greatly, can prolong the life of each part.

The lower end of the guide frame 1 is connected with a guide seat 14, a guide block 15 is assembled in the guide seat 14, and a drill rod 16 is installed in the guide block 15 in a penetrating mode. A leaf spring 18 is also mounted in the guide shoe 14, the leaf spring 18 being located on both sides of the drill rod 16, the lower end of the leaf spring 18 being located above the guide block 15.

In order to further increase the falling inertia of the hammer block 2, an air cylinder 17 is further arranged on the top wall of the guide frame 1, the air cylinder 17 is positioned in the inner cavity 3 of the guide frame 1, the telescopic rod of the air cylinder 17 extends to the hammer block 2, and the air cylinder 17 is compressed when the hammer block 2 rises; when the lifting hook 7 releases the hammer block 2, the hammer block 2 starts to fall under the action of self gravity, the compressed telescopic rod of the air cylinder 17 extends out at the moment, downward thrust is applied to the hammer block 2, the falling speed of the hammer block 2 can be increased, and the impact force on the drill rod 16 is further increased.

The utility model discloses a theory of operation and concrete implementation mode:

when the guide frame is used, the guide frame 1 is fixedly arranged on a working vehicle, and a hydraulic oil path of the hydraulic cylinder 6 is communicated with a hydraulic oil path of the working vehicle. The telescopic rod of the hydraulic cylinder 6 is controlled by the controller to drive the lifting hook 7 to extend downwards, and meanwhile, the telescopic device 13 meeting the gear requirement acts to control the corresponding limiting block 12 to extend. The lifting hook 7 rocks about under the action of gravity, can catch on round pin axle 8 naturally when 7 run into round pin axle 8 on 2 tops of hammer block, and 6 telescopic links of pneumatic cylinder are upwards shrink afterwards, pull and drive 2 shifts up of hammer block, 2 compression cylinder 17's of hammer block telescopic link. When the lifting hook 7 moves upwards to touch the limiting block 12, the limiting block 12 blocks one corner of the lifting hook 7, the lifting hook 7 continues to move upwards so as to be deviated from the pin shaft 8, the hammer block 2 falls under the action of gravity, meanwhile, the cylinder 17 gives thrust to the hammer block 2, the hammer block 2 rapidly falls and impacts the top end of the drill rod 16, and the drill rod 16 crushes large materials such as hard pavements or mountain stones under the action of strong impact force. Because the effect of gravity, two lifting hooks 7 can rock about the in-process that moves down, no matter how the whole slope of equipment, and the suitable angle can always be found to lifting hook 7 and catch on round pin axle 2, guarantees going on smoothly of traction work, realizes the broken operation of multi-angle.

When the hammer block 2 is strongly collided with the drill rod 16, strong vibration is generated, and the hammer block 2 is separated from the telescopic rod of the hydraulic cylinder 6 in the falling process, so that the vibration of the hammer block 2 cannot cause the vibration of the hydraulic cylinder 6 and the telescopic rod thereof, the normal work of the hydraulic cylinder 6 cannot be influenced, the service life of the hydraulic cylinder 6 can be prolonged, and the stability of the whole device can be improved.

After the primary crushing is finished, the telescopic rod of the hydraulic cylinder 6 moves downwards again, so that the lifting hook 7 hooks the hammer block pin shaft 8, the hammer block 2 is lifted again under the traction force of the hydraulic cylinder 6, and the next descending is prepared for carrying out the crushing work. The operator can contract specific position through controller control pneumatic cylinder, and the stopper 12 that corresponds the position stretches out simultaneously, and the stopper of other positions contracts back to the height of rising of control hammer block 2 satisfies the impact force requirement of different gears, realizes the reliable impact of many gears dynamics.

The embodiment also connects the tamper plate 19 at the lower end of the drill rod 16, so that the utility model is used as a tamper or a pile driver, and the application field is widened. When the tamping plate 19 is used as a crushing device, the tamping plate contacts with materials to be tamped and carries out tamping action by means of strong impact force of the drill rod 16. Because the big impact of the hammer block 2 can not influence the normal work of the hydraulic cylinder 6, the traction force of the hydraulic cylinder 6 and the weight of the hammer block 2 can be improved as much as possible, so that the impact force of the hammer block 2 is further improved, the force for crushing or tamping work is effectively improved, the work efficiency is improved, and the stability of the equipment is also ensured.
