Drilling and piling device of highway guardrail breakdown van

Abstract

The invention provides a drilling and piling device of a highway guardrail breakdown van, and belongs to highway guardrail breakdown vans. The drilling and piling device comprises a rotary assembly, a rotary platform, a drill rod assembly, a hammer drill assembly, a transverse slide way assembly and a stand column assembly; the rotary platform is installed on the rotary assembly, and the transverse slide way assembly is installed on the rotary platform; one end of the transverse slide way assembly is connected with the stand column assembly, and the hammer drill assembly is installed on the stand column assembly and slides on the stand column assembly; and the side face of the lower end of the stand column assembly is connected with the drill rod assembly. The drilling and piling device has the advantages that the multiple functions of piling, pile pulling and drilling can be achieved through one device, the device is multipurpose, the assembling space is saved, the whole van is small in size, light in weight and flexible and convenient to operate and control, turning is easy and site transferring is convenient during construction, the manufacturing cost is low, and the cost performance of the device is high. The hydraulic impact drilling technology is adopted in the device, and compared with traditional pneumatic impact drilling, the efficiency is high, the labor intensity is low, energy consumption is low, environment friendliness and safety are achieved, and operation is convenient.

Description

technical field [0001] The invention relates to a highway guardrail emergency repair vehicle, in particular to a drilling and piling device for a highway guardrail emergency repair vehicle. Background technique [0002] At present, the guardrail repair vehicles sold and in use on the market have the functions of drilling and piling. When drilling, pneumatic impactors and large air compressors are used for drilling, and hydraulic hammers are used for piling. Pile driving or drilling is divided into two parts. Different working mechanical devices, two different working mechanical devices cannot be installed on the column at the same time, and one kind of working mechanical device can only do one kind of work; when doing another kind of work, another working device should be replaced; the column Only the vertical adjustment of the pitch direction can be performed, and the vertical adjustment of the left and right directions of the column cannot be performed. When changing from...

Problems solved by technology

[0002] At present, the guardrail repair vehicles sold and in use on the market have the functions of drilling and piling. When drilling, pneumatic impactors and large air compressors are used for drilling, and hydraulic hammers are used for piling. Pile driving or drilling is divided into two parts. Different working mechanical devices, two different working mechanical devices cannot be installed on the column at the same time, and one kind of working mechanical device can only do one kind of work; when doing another kind of work, another working device should be replaced; the column Only the vertical adjustment in the pitch direction can be performed, and the verticality adjustment in the left and right directions of the column cannot be performed

When changing from piling work to drilling work, the drilling work system needs to be replaced, and workers need to climb up on a higher column to replace it. It is very difficult for workers to replace the piling work system or drilling work system, which requires the cooperation of multiple workers or with the help of Ladders can be used to complete the replacement of the piling system or the drilling system. The construction is time-consuming and laborious, and the labor intensity of the workers is high, which increases the construction time and increases the construction cost.
