Embodiment Construction

[0022] First, in conjunction with the accompanying drawings, the key structure and working principle of the present invention are introduced.

[0023] Figure 4 . The cross-sectional structure of the truss column of the present invention. The section can also be square. 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 discloses a wheeled electric piling machine with light weight, low construction cost and high construction efficiency. A reasonable mechanical structural design is adopted, so that the weight of the piling machine is reduced to about a quarter of the weight of a walking type piling machine with the same construction capability. A wheeled walking device of the piling machine consists of a driving wheel and a load bearing wheel, wherein a motor is used for driving the piling machine to walk through a speed reducer and a chain (or a belt); a piling machine platform and an upright post have truss structures; the front end of the piling machine platform has a truss structure connected integrally with an upright post revolving shaft bracket; one face of the upright post is provided with a steel plate and an inclined strut behind the steel plate, and the other three faces have rectangular truss structures welded by using angle steel; and a revolving support is rotated by pushing and pulling an oil cylinder. The wheeled electric piling machine with light weight and flexible walking is very suitable for construction of CFG (Cement Flyash Gravel) piles, rammed ash piles, prefabricated pile conducted holes, deep mixing and the like, has construction efficiency far higher than that of the walking type piling machine, and is accordant with the environmental protection requirement; and energy is saved, waste gas is not emitted and noise is avoided.

Description

[0001] The invention relates to a pile machine, in particular to a wheeled electric 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 r...
