Guide rod type diesel pile hammer with vertical landing gear

Abstract

The invention discloses a guide rod type diesel pile hammer with a vertical landing gear, which comprises a top transverse beam, a guide rod, a cylinder hammer and a piston, wherein the top transverse beam and the piston are respectively installed on the upper and the lower ends of the guide rod; the cylinder hammer can slide upwards and downwards along the guide rod; a landing gear is verticallyarranged outside the cylinder hammer, and is provided with a lifting hook and a hammer lifting hook; the hammer lifting hook corresponds to a cylinder hammer hook groove on the cylinder hammer, and is connected with a link mechanism of the hammer lifting hook; and a decoupling stop block and a hammer hooking stop block are fixedly connected between the top transverse beam and the piston. The pilehammer has the advantages of completely preventing the landing gear from colliding with the cylinder hammer and the top transverse beam in a work process, automatically hooking and decoupling the landing gear and facilitating the operation.

Description

technical field [0001] The invention relates to equipment for building foundation construction, more specifically, to a landing gear of a guide rod type diesel piling hammer. Background technique [0002] Guide rod type diesel piling hammer (hereinafter referred to as piling hammer) is a kind of piling equipment for construction foundation engineering. It is widely used because of its advantages such as large impact force, high work efficiency, strong reliability, and convenient use and maintenance. Existing piling hammers are all composed of top beam, landing gear, cylinder hammer, piston, guide rod and oil circuit system. The top beam and piston are respectively fixed on the upper and lower ends of the guide rod. Between the top beam and the piston, it moves up and down guided by the guide rod, and the landing gear is above the cylinder hammer. [0003] When the piling hammer is started, the landing gear falls along the guide rod and collides with the upper plane of the c...

AI Technical Summary

Problems solved by technology

[0004] Because the landing gear is located between the top beam and the cylinder hammer in the existing piling hammer, there are the following defects in actual use: one is that the distance between the landing gear and the bouncing cylinder hammer is not easy to control, because the landing gear and the cylinder hammer are in the In the same vertical working plane, when the oil supply throttle is not operated properly, the cylinder hammer bounces vertically upward after the explosion and will collide with the landing gear again, resulting in the "pinning phenomenon", that is, after the cylinder hammer accidentally collides with the landing gear, The hammer hook of the landing gear is hooked to the pin shaft in the cylinder hammer, which can easily lead to damage to the landing gear frame and the breakage of the hammer hook shaft. scrapped

Second, the distance between the landing gear and the top beam is not easy to control

Also because the undercarriage and the top beam are also in the same vertical working plane, when the softness and density of the ground are different, the penetration of the pile varies greatly. If the landing gear sinks faster, the top beam hits the landing gear and pulls back the landing gear. In this way, the external force wire rope is easily broken, and in severe cases, the pile driving frame is deformed and damaged, and even the pile driving frame is overturned.

The third is that every time the piling hammer is restarted, the landing gear is decoupled from the pin shaft of the cylinder hammer by manpower, and the labor cost is high and the labor intensity is high.
