Special tool for maintenance of corrugated beam barrier of highway

Abstract

The invention discloses a special tool for maintenance of a corrugated beam barrier of a highway and relates to the technical field of barrier maintenance. By the adoption of the special tool for maintenance of the corrugated beam barrier of the highway, the situation that the barrier bounces and injures people in the dismantling process can be avoided, and a repairing function and a short-distance transferring function are achieved. The special tool for maintenance of the corrugated beam barrier of the highway comprises a main rod and a traveling support. A long cross arm and a short cross arm are arranged at the front end of the main rod, wherein the long cross arm is located at the top end of the main rod, and the short cross arm is located behind the long cross arm, in parallel to the long cross arm and is provided with a gap. A movable supporting structure is arranged at the top end of the traveling support. The main rod is provided with a supporting section. The supporting section of the main rod is arranged on the movable supporting structure. According to the special tool for maintenance of the corrugated beam barrier of the highway, the main rod is arranged to be in an F shape, and a corrugated beam protective plate right can be placed in the gap between the long cross arm and the short cross arm. During dismantling, the long cross arm at the end of the main rod is clamped on the back side of a corrugated beam, the short cross arm is clamped on the front side of the corrugated beam, and even if the barrier bounces elastically when screws are separated from the barrier and stand columns are installed, the situation that the barrier bounces and injures people is avoided under the restraint of the short cross arm. Meanwhile, a clamping opening formed by the F shape can also have shaping and repairing effects on the corrugated beam protective plate which deforms slightly.

Description

technical field [0001] The invention relates to the technical field of guardrail maintenance, in particular to the maintenance of highway wave-beam guardrails, in particular to a tool for transporting guardrail boards, installing load-bearing bolts, adjusting alignment and preventing rebound. Background technique [0002] The maintenance work of the damaged road guardrail can be mainly divided into two parts: the removal and installation of the wave beam guardrail and the removal / driving of the column. There are special piling trucks for pulling up the columns, while the removal and installation of the guardrails still use traditional tools, which are completely manual operations. There are problems such as low work efficiency, high labor intensity and potential safety hazards during construction. [0003] There are also two situations after the wave beam guardrail is deformed by impact. One is that the deformation is slight (excluding the deformation of the material itself...

AI Technical Summary

Problems solved by technology

But when implementing the second case, refer to Figure 8 , during the removal process, due to the large deformation elastic stress of the wave beam guardrail 4, when the guardrail screw 42 is removed, once the screw 42 is separated from the guardrail post 41, the end of the guardrail 4 will bounce up, causing injury

[0004] In addition, after the guardrail is replaced, the new guardrail board needs to be replaced in place. At present, it is a purely manual operation method, which has high requirements for the individual strength of the construction workers, and the labor intensity is high. Moreover, it is difficult to grasp the point of transportation, and it is not convenient to exert force. Hazardous hazards such as personal injury and low working efficiency are likely to occur
