Embodiment Construction

[0019] First, in conjunction with the accompanying drawings, the key structure and working principle of the present invention are introduced.

[0020] figure 2 . The cross-sectional structure of the truss column of the present invention. The unique feature is that one of the four sides of the column is a steel plate, and the other three sides are angle steel. Behind the steel plate, there are diagonal braces along the diagonal direction of the section. It is advisable to choose unequal angle steel for angle steel and place the long side on the outer surface with the largest force. Two channel steels are welded on both sides of the steel plate as column slideways. Compared with the column with steel plate welding on all four sides on the existing various pile machines, the column with diagonal brace behind the steel plate on one side can reduce the weight by half and have similar bending and torsional strength.

Abstract

The invention relates to an electric wheel type pile driver which has light weight, low cost and high construction efficiency. The weight of the electric wheel type pile driver is reduced to about a quarter of the weight of a walking type pile driver which has the same construction capability by adopting reasonable mechanical structure design. The electric wheel type pile driver is characterized in that a wheel type traveling device comprises a plurality of groups of left and right independent rigid driving wheels and follower wheels capable of follow-up turning, wherein the left and right driving wheels are respectively independent, the driving wheels positioned at a same side are connected through chains (or belts) to synchronously drive the pile driver to walk so that the pile driver is similar to a crawler-type pile driver without installing a crawler; an upright column is in a rectangular truss structure with one surface provided with a steel plate and inclined struts at the rear of the steel plate and other three surfaces welded by angle steels; and a roller wheel type pivoting support is pushed and pulled to rotate by an oil cylinder. The electric wheel type pile driver which has light weight and flexible traveling is quite suitable for the construction of CFG (Cement Flyash Gravel) piles, rammed bulb slag piles, preformed pile lead holes, deep-layer mixing, and the like, has construction efficiency much higher that of the walking type pile driver and saves the energy without exhausting waste gas or making noises, thereby meeting the requirements of environmental protection.

Description

[0001] The invention relates to a pile machine, in particular to an electric wheeled pile driver. Background technique [0002] Pile drivers are necessary equipment for pile foundation and foundation reinforcement projects in the construction industry. The current pile driver has two characteristics: one is heavy and the other is expensive. Now the largest and lightest small walking pile driver is used on the construction site, with a weight of about 20 tons. Because of the weight, pile drivers are mostly crawler-type or walking-type and rarely use wheel-type. And because it is expensive, the migrant workers who use it for specific operations cannot afford it. Migrant workers are now the largest group of employees in the construction industry. They require the design of pile drivers with low sales prices that allow them to buy them with loans and funds, so as to get rid of the situation where they have no production tools and can only sell their labor. This is a Reasonable ...
