Double-rod superposition type hydraulic pile hammer

Abstract

The invention relates to the technical field of double-rod superposition type hydraulic pile hammers and discloses a double-rod superposition type hydraulic pile hammer. The double-rod superposition type hydraulic pile hammer comprises an upper hammer rack, wherein the bottom of the upper hammer rack is fixedly connected with an upper rack fixing pin, the left side and the right side of the bottomof the upper rack fixing pin are fixedly connected with guide rods, and the bottoms of the guide rods are fixedly connected with an upper hammer body. The structural design of an upper copper sleeveand a lower copper sleeve is adopted; the wear resistance among the upper hammer body, the lower hammer body and the guide rod can be improved, and the resistance can be reduced; through the structural design of the energy accumulator, the striking frequency of the hammer body can be increased, and the pressure damage of the pipe can be reduced; through the structural design of the upper hammer rack, the stroke of the piston rods of the double-rod superposition type hydraulic pile hammer can be adjusted at any time according to the number of the superposition hammer bodies, and therefore the double-rod superposition type hydraulic pile hammer can achieve the purpose of improving the working efficiency of an original superposition type addition type hydraulic pile hammer.

Description

technical field [0001] The invention relates to the technical field of a double-rod superimposed hydraulic piling hammer, in particular to a double-rod superimposed hydraulic piling hammer. Background technique [0002] Hydraulic piling hammers mainly include conventional type, high-frequency type and non-resonance type (usually non-resonance type is also high-frequency type). For construction in soil, the high-frequency type piling hammer is suitable for sandy soil, while the non-resonance type is suitable for areas with strict restrictions on vibration. A piling machine that goes into the ground. Compared with the traditional piling hammer, it has the advantages of low noise, no pollution, small vibration, etc., meets the requirements of environmental protection, and has excellent dynamic characteristics and controllability. [0003] The existing superimposed plus type hydraulic piling hammer can only limit one kind of piling force, which can neither increase the piling ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a double-rod superimposed hydraulic piling hammer, which has the advantages of being able to improve the working efficiency of the original superimposed plus hydraulic piling hammer, and solves the problem of the existing superimposed plus hydraulic piling hammer. Only one type of piling strength can be limited, neither can be increased nor increased, so that different piles need a fixed type of piling hammer during construction, thereby reducing the work efficiency during construction
