Round damping impact hammer with lubricating structure

Abstract

The invention relates to a circular shock-absorbing impact hammer with a lubricating structure, which is characterized in that an original square hammer shell is changed into a circular hammer shell, so that the problem that a weld joint of the original square hammer shell is easy to tear is solved by utilizing the rigidity and the strength of the circular structure; a worker only needs to inject oil into one surface without interference of the hammer core through the oil supply nozzle, lubricating oil can enter the communicating seats along the lubricating oil channels, and the communicating seats can connect the lubricating oil channels on the same hammer core rail through a two-way pipe. And after being bent by 90 degrees through the bending pipe, the hammer core is fed into the faying surface of the hammer core and the hammer core rail, oil is fed through the oil outlet hole to lubricate the hammer core, the hammer core lifting hammer connecting seat is improved, the damping chamber is arranged, the damping effect is improved, and the service life of equipment is prolonged.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a circular shock-absorbing impact hammer with a lubricating structure. Background technique [0002] Smashing wooden or stone piles into the ground, in order to make the building foundation firm, because if the ground buildings are to be built on the ground, the ground must bear a lot of pressure, and the ground must have sufficient strength to resist the pressure. This is often difficult to achieve, so the ground bearing the building must be reinforced or the bearing method of the ground must be improved, so I thought of piling on the foundation, so that most of the weight of the building can be transmitted to a position deep below the ground through the piles , because the foundation of this location is much larger than the ground bearing capacity. [0003] During piling construction, the impact hammer uses the impact energy of the hammer core to overcome the resistance o...

Problems solved by technology

[0010] Using the above technical solution, by changing the original square hammer shell into a round hammer shell, and then using the rigidity and strength of the circular structure, the problem of easy tearing at the weld seam of the square hammer shell in the past is solved, and at the same time, it has wear and tear. Small resistance and beautiful appearance, and when piling underwater, the circular hammer shell can better seal the surface of the shell than the square structure, so that it can maintain high sealing performance underwater. The circular hammer shell adopts the original square shape The hammer core makes the hammer core rise and fall along the hammer frame, so the part of the hammer shell that is not covered by the hammer core will form an air passage, so that when the impact hammer is piling underwater, the hammer core will The air pressure brought out during the lifting process will be quickly discharged through the air channel to increase the impact force of the impact hammer during underwater piling. At the same time, in order to ensure that the hammer core and the hammer core track can be fully lubricated during the piling process, it is installed on each hammer core track. The lubricating oil passage distributed in the axial direction allows workers to fill the oil supply nozzle in the exposed area above the impact hammer, so that the lubricating oil sinks through the lubricating oil passage, and then sends the lubricating oil to the lower hammer core track and the hammer core through the oil outlet module. With multiple contact surfaces between the hammer cores, the lubricating oil can be applied to the entire hammer core, reducing the friction of the hammer core during piling, improving piling efficiency and equipment service life
