Problems solved by technology
The strength of the ramming depends on the falling height of the rammer, but because the length of the lifting arm of the lifting equipment is generally limited, the lifting height of the hoisting equipment to the rammer is also limited, and the intensity of the ramming is also limited.
In order to improve the tamping effect, the length of the lifting arm of the lifting equipment can only be continuously increased, and the longer the length of the lifting arm, the more equipment costs and potential safety hazards

[0078] Furthermore, please also refer to figure 1 and figure 2 , a kind of specific implementation mode that the present invention provides again on the basis of above-mentioned implementation mode is as follows:
[0079] The lifting base 20 is provided with a guide structure 214 for the traction rope 213 to pass through, and the guide structure 214 is used to limit the direction of the pulling force exerted on the hook 211 when the traction rope 213 is pulled.
[0080]The guide structure 214 is arranged above the hook 211, and the hook 211 is an L-shaped rod-shaped or L-shaped bent plate-shaped structure, so as to better provide the torque for the hook 211 to be unhooked, and ensure that the pulling rope 213 can be pulled smoothly. The hook 211 is unhooked, and then the rammer 10 is released.
[0081] The slot 13 is a ring-shaped structure arranged around the lifting base 20 , which can prevent the hook 211 from being unhooked due to the relative rotation between the ramme...

The invention belongs to the technical field of tamping machines. An implosion type tamping mechanism comprises a tamping hammer and a lifting seat; the tamping hammer is used for falling down to tamp the ground; the lifting seat is used for being connected with a lifting mechanism; a locking assembly used for being connected with the tamping hammer is arranged on the lower portion of the lifting seat; an explosion chamber with an opening facing the tamping hammer is arranged in the lifting seat; and the lifting seat is provided with a fuel supply assembly communicated with the explosion chamber and a detonating assembly used for igniting and detonating fuel in the explosion chamber. An implosion type tamping machine comprises the implosion type tamping mechanism and the lifting mechanism connected with the implosion type tamping mechanism. Falling of the tamping hammer can be accelerated through thrust generated by explosion of the fuel in the explosion chamber, so that the tamping hammer can have the higher falling speed at the same height, relatively large tamping impulse can be generated when the tamping hammer tamps the ground, the tamping effect is improved, and under the requirement of the same tamping force, the lifting height of the tamping hammer can be reduced and the requirement on the length of a lifting arm of the lifting mechanism is reduced.
Description
technical field [0001] The invention belongs to the technical field of dynamic tamping machines, and more specifically relates to an implosion type tamping mechanism and an implosion type dynamic tamping machine. Background technique [0002] The dynamic tamping machine is a construction engineering equipment used for foundation treatment. Its working principle is to use special lifting equipment to lift the rammer and release it, and use the gravity of the rammer to ram the ground to compact the soil on the ground. The intensity of its ramming depends on the falling height of the rammer, but because the lifting arm of the lifting device is generally limited in length, the lifting height of the rammer is also limited by the hoisting device, and thus the intensity of the ramming is also limited. In order to improve the tamping effect, the length of the boom of the lifting equipment can only be continuously increased, and the longer the length of the boom, the more equipment c...
