Description

Circular shock-absorbing impact hammer with lubricating structure

Technical Field

The invention relates to the field of engineering machinery, in particular to a circular shock-absorbing impact hammer with a lubricating structure.

Background

The construction method is characterized in that a timber pile or a stone pile is hammered into the ground, in order to make the foundation of the building firm, if the ground building is built on the ground, the ground is subjected to great pressure, the ground is required to have enough strength to resist the pressure, which is difficult to achieve, the ground bearing the building is required to be reinforced or the bearing mode of the ground is improved, so that the foundation is considered to be piled, most of the weight of the building is transmitted to a position deep below the ground through the pile, and the bearing capacity of the ground at the position is much larger than that of the ground.

When in construction and piling, the impact hammer utilizes the impact energy of the hammer core to overcome the resistance of foundation soil to the pile, and then drives the hammer core to move along the hammer frame to drive the pile to a preset depth, but the impact hammer has the following defects:

1. for preventing hammer core and hammer carrier from rubbing for a long time, the workman can scribble the lubricating oil on hammer core and hammer carrier, nevertheless because the clearance is very little and the jump bit is bulky between hammer core and the hammer carrier, the hammer core can only scribble lubricating oil in the naked region in top when scribbling, rethread hammer core goes up and down to drive lubricating oil and scribbles partial hammer carrier, lead to the hammer core to scribble lubricating oil after must improving the take the altitude when the pile, and also be in same position all the time to hammer carrier lubrication region, and then influence the life of hammer core and hammer carrier.

2. The existing impact hammer protects a pile body when in piling, a replacement part can be placed between a hammer core and a pile head, the replacement pile replaces the pile head to bear the impact force of the hammer core, then the impact force is transmitted to the pile head for piling, if the pile touches a hard stone layer in the piling process, the pile body also transmits the reaction force to the replacement pile, the replacement pile is enabled to generate the reaction shock to the whole hammer shell, the parts in the hammer shell are damaged after being vibrated for a long time, the service life of the parts is greatly shortened, at present, some measures for damping the reaction force are provided, the replacement pile and the hammer body are abutted to damp through a polyurethane block, but the mode has poor damping effect, the polyurethane blocks with different sizes need to be replaced when corresponding to damping environments with different specifications, and the damping module is caused to be manufactured again frequently and the cost is too high.

3. The existing impact hammer can lift the hammer core to a certain height through the top oil cylinder and then quickly release the hammer core when piling, the anvil block is driven by the hammer core in a following impact falling mode, the anvil block is transmitted to the pile, the pile made of materials such as a wooden pile or a stone pile is hammered into the deep part of the ground, the acting force on the hammer core when the hammer is lifted and dropped is very large, the reacting force of the hammer core can impact the top oil cylinder, and if the impact energy is not absorbed, the hammer core and the top oil cylinder can be damaged.

4. The hammer frame of the existing impact hammer is arranged in a square hammer shell welded by four square pipes, but the welding seam of the impact hammer shell arranged in a square mode is easy to crack in the using process, particularly under the condition of severe working conditions, the impact hammer is particularly obvious, meanwhile, along with the development of offshore artificial islands and coastal sea wall revetment engineering projects, the impact hammer also needs to carry out underwater construction and pile driving through a pile frame type pile driving barge, and the problem that the existing square hammer shell is insufficient in tightness and impact force exists when the existing square hammer shell is constructed underwater.
