Vibrating hammer with side clamping function

Abstract

The invention discloses a vibrating hammer with a side clamping function. The vibrating hammer comprises a vibrating box and a sliding clamping device arranged on the side surface of the vibrating box, wherein the vibrating box comprises two eccentric wheels and a rotary motor; the two eccentric wheels are meshed with each other and driven by the rotary motor; the side clamping device comprises afixed arm and a rotating arm; the rotating arm can perform eccentric rotation around a pivot shaft; and clamping pads are arranged in groups at the movable end of each of the fixed arm and the rotating arm. The vibrating hammer with the side clamping function has the benefits as follows: the side clamping device is additionally arranged on the side edge of the vibrating box body and comprises an upper clamping device and a lower clamping device, the two groups of clamping pads are used for clamping the side surface of a pile body, and the vibration is transmitted to the pile body for piling; for deep piling, all needed is to decompose the overall pile sinking process into multiple operation steps, the elevation height of the vibrating hammer is reduced by adjusting the clamping position ofthe middle of the pile body for multiple times, the operation is more flexible, the length of the connecting arm of the vibrating hammer is reduced, and the mechanical structure of the vibrating hammer is simplified.

Description

technical field [0001] The invention relates to the field of pile sinking and pulling equipment for construction engineering, in particular to a side-clamped vibratory hammer. Background technique [0002] The vibratory hammer is a kind of equipment that generates a strong exciting force to drive the pile into the ground after being driven. It is widely used in pulling out piles in various building foundations and municipal engineering. When the vibratory hammer is running, the total number of even-numbered eccentric wheels rotates at a high speed to generate vibration force. This force causes the pile body to generate sine wave vertical vibration, forcing the soil around the pile body to liquefy, displace and move the soil layer. Under the action of the weight of the vibrating hammer, the pile body is cut into the ground. In the prior art, the pile body is generally fixed on the bottom end of the vibratory hammer through a clamper, and the vibratory hammer vibrates and str...

AI Technical Summary

Problems solved by technology

Since the vibratory hammer needs to be lifted higher than the top of the vertical pile when the vertical pile is installed, this requires that the vibratory hammer must be raised to a very high height, which is not only suitable for engineering equipment such as excavators or drilling rigs that fix the vibratory hammer. There are requirements for the length of the connecting arm, which makes the structure of the equipment more complicated, especially for deep piles, large or heavy equipment must be used; at the same time, there are also requirements for the height of the construction environment. For some construction environments with limited space, the vibratory hammer may not be able to work
