Technical Field

The utility model relates to an engineering machine tool field, in particular to protection pile body improves replacing of pile efficiency and beats mechanism.

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 the construction is driven, the pile driving hammer overcomes the resistance of foundation soil to the pile by utilizing the impact energy of the pile driving hammer, and drives the pile into the preset depth, because most of the pile bodies are cement piles, the pile heads are brittle, if the driving force of the pile driving hammer is too large, the pile bodies are easy to break, the driving force of the pile driving hammer is reduced, and the deep part of the ground, which is convenient to drive, of the pile bodies cannot be known, so that the construction speed is influenced.

By adopting the technical scheme, the diameter of the impact part is smaller than that of the hammer core, the diameter of the impact bearing surface is consistent with that of the impact part, the diameter of the diffusion surface is larger than that of the impact bearing surface, the hammering force of the hammer core is transmitted to the pile cap through the replacing body by arranging the replacing body, so that the pile body in the pile cap is protected from being broken, meanwhile, the pile cap is prevented from being deformed, meanwhile, the impact part with the cross section smaller than that of the hammer core is arranged on the hammer core, and the area of the punching end of the hammer body is reduced by the impact part with the cross section smaller than that of the hammer core, so that the resistance in punching is reduced, the effect of the pile hammer in piling is better, the structure is simple, the diffusion surface and the impact bearing surface are arranged, the cross section of the diffusion surface is larger than that of the impact bearing surface with the smaller cross section, the replacing body absorbs the punching force through the impact bearing surface with the smaller cross section, and then diffuses through the diffusion surface with the larger cross section, the impact force on the pile cap is evenly distributed, the pile body is prevented from being damaged and broken, and when the mechanism is used on a pile driving hammer, the pile driving effect can be improved, and the pile body can be protected from being damaged and broken.

Foretell a protection pile body improves and replaces mechanism of beating of pile efficiency, and then further set up to: the impact-bearing surface of the replacing beating body is provided with a hammer pad matched with the contact surface of the impact part between the impact-bearing surface and the impact part, the replacing beating body extends towards one end of the impact part around the impact-bearing surface, and a impact-bearing cavity for accommodating the hammer pad is formed inside the replacing beating body.

By adopting the technical scheme, the diameter of the hammer pad is consistent with that of the impact part, and the hammer pad is arranged on the impact bearing surface and the impact part, so that the hammer core sends impact force to the hollow secondary pile through the hammer pad, the hammering peak value is reduced, and the pile head is protected from being broken.

Foretell a protection pile body improves and replaces mechanism of beating of pile efficiency, and then further set up to: the periphery of the corresponding impact bearing cavity of the impact replacing body is sleeved with an impact replacing cushion pad, and the impact replacing cushion pad is abutted to the punching cavity.

Adopt above-mentioned technical scheme, replace beating the blotter through setting up, prevent to replace beating the anti-shock impact punching press chamber after the hammering, improve equipment stability and life.

Foretell a protection pile body improves and replaces mechanism of beating of pile efficiency, and then further set up to: and a pile body cushion pad is arranged between the pile cap and the pile body.

By adopting the technical scheme, the pile body cushion is arranged, so that the pile cap can buffer the hammering force through the pile body cushion, and the pile body cushion can be a wood cushion or a paper cushion and is contacted with the pile head.

The present invention will be further described with reference to the accompanying drawings.
