Guide rod type hydraulic piling hammer

Abstract

The invention discloses a guide rod type hydraulic piling hammer. The guide rod type hydraulic piling hammer comprises an upper cross beam, guide rods and a lower cross beam; a pile hammer is supported on the guide rods in a sliding manner; the upper cross beam and the lower cross beam are respectively fixedly mounted at the inner ends of the guide rods; the guide rods are fixedly connected with amain supporting cross beam; a hydraulic cylinder is mounted on the main supporting cross beam and is parallel to the guide rods; an extending end of a piston rod of the hydraulic cylinder is connected with the pile hammer; and a rodless cavity of the hydraulic cylinder communicates with a secondary oil tank. The lower end of the cylinder body of the hydraulic cylinder is supported to the main supporting cross beam; the upper end of the cylinder body is fixedly connected with the upper supporting cross beam; and the upper supporting cross beam is fixedly supported on the guide rods. The secondary oil tank is supported on the upper supporting cross beam; a ventilating hole is formed in the secondary oil tank; and an air filter is mounted on the ventilating hole. The extending end of the piston rod is connected with the pile hammer through a spherical hinge. The guide rod type hydraulic piling hammer is simple and reasonable in structure, has low influence on surrounding environment, andcan realize high-frequency high-energy piling.

Description

technical field [0001] The invention relates to a piling machine used for building foundation construction, in particular to a hydraulically driven guide rod type piling hammer. Background technique [0002] Pile foundation is a foundation form widely used in construction projects such as marine engineering, high-rise buildings, bridges and high-speed railways. Pile foundations are generally composed of piles placed in the soil and caps that accept the upper structure. The load of the building is transmitted to the deep soil layer with a large bearing capacity, or the weak soil layer is squeezed to improve the bearing capacity and compactness of the soil, thereby ensuring the stability of the building and reducing foundation settlement. [0003] Pile machinery is the necessary equipment for penetrating piles into the ground to strengthen the bearing capacity of the foundation. Guide rod type diesel piling hammer is one of the important piling machinery. Its working principl...

Problems solved by technology

The guide rod diesel hammer has the characteristics of simple structure and convenient operation and maintenance. However, when the guide rod diesel hammer is working, a large amount of fuel chemical energy is not converted into useful striking kinetic energy but converted into heat energy, and the effective energy conversion rate is low; The cavity structure is rough, the impact and vibration are strong, it is difficult to form uniform atomized fuel in the cylinder cavity, and it is easy to cause combustion deterioration, incomplete fuel combustion, high exhaust smoke, billowing black smoke, and a large amount of harmful smoke and gas. Soot particles; In addition to serious air pollution during the working process of the guide rod diesel hammer, it will also produce severe explosion vibration and explosion impact, causing strong low-frequency and high-intensity noise

Severe noise pollution and serious air pollution not only form serious pollution to the environment, but also seriously affect people's working and living environment

The double pollution of guide rod diesel piling hammer has become its fatal flaw, so many areas have restricted the application of guide rod diesel piling hammer
