Technical Field

[0001] The utility model belongs to the technical field of diesel pile hammer decoupling devices, in particular to a guide rod type diesel pile hammer cylinder hydraulic decoupling device. Background Art

[0002] At present, the explosion principle of the guide rod diesel pile hammer is to hook the cylinder with a hammer hook, and lift the cylinder upward with a wire rope. When it is lifted to a certain height, the operator manually pulls the rope connected to the hammer hook lever under the hammer, thereby separating the hammer hook and the hammer pin. The cylinder freely falls downward to impact the compression oil pump and then explodes. Such a structure requires manual operation under the hammer, which is very unsafe and prone to safety accidents. Utility Model Content

[0005] As a further description of the above technical solution:

[0006] The hammer hook mechanism includes a hammer hook body and a hammer hook lever, the hammer hook lever is hinged on the sliding member, the hammer hook body is connected to the hammer hook lever, one end of the hammer hook body is hinged to the telescopic end of the hydraulic cylinder, and the other end of the hammer hook body hooks the cylinder body.

[0007] As a further description of the above technical solution:

[0008] A hammer lifting pin is provided on the cylinder body, and the hammer hook body hooks the hammer lifting pin.

[0009] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0010] 1. In the utility model, the hammer hook mechanism is connected by a hydraulic cylinder, and the hydraulic control valve is used to control the hammer hook mechanism to hook the cylinder body. In this way, the operator can remotely use the hydraulic valve to control the hydraulic cylinder, avoiding manual operation under the hammer, avoiding safety accidents, and improving the safety factor of the pile hammer operation.

[0011] 2. In the present invention, the hammer hook lever is controlled by controlling the contraction of the hydraulic cylinder. The hammer hook lever can hook the hammer pin to lift the cylinder body to a certain height. BRIEF DESCRIPTION OF THE DRAWINGS
