Concrete anti-collision guardrail joint cutting device and using method thereof

Abstract

The invention relates to the technical field of guardrail machining, in particular to a concrete anti-collision guardrail joint cutting device and a using method thereof.The concrete anti-collision guardrail joint cutting device comprises a saw blade and a cutting mechanism and further comprises a mounting frame, a reciprocating mechanism, a lifting mechanism and at least one adjusting mechanism; the mounting frame comprises a vertical section and a horizontal section which are integrally connected; one end, close to the guardrail, of the horizontal section is connected with the cutting mechanism; the reciprocating mechanism is used for driving the vertical section to get close to or away from the guardrail; the lifting mechanism is used for driving the vertical section to lift; according to the designed concrete anti-collision guardrail joint cutting device, the vertical section is conveniently driven to be close to or away from the guardrail through the reciprocating mechanism, the vertical section is conveniently driven to ascend and descend through the lifting mechanism, and the guardrails with different section shapes are conveniently cut through cooperation of the mounting frame, the reciprocating mechanism, the lifting mechanism and the adjusting mechanism; and the application range of the concrete anti-collision guardrail joint cutting device is widened while the false joint cutting depth is controlled.

Description

technical field [0001] The present application relates to the technical field of guardrail processing, in particular to a concrete anti-collision guardrail cutting device and a use method thereof. Background technique [0002] With the rapid development of my country's economy, the mileage of roads has been increasing. When building viaducts or slope roads, in order to reduce the loss of control of vehicles due to traffic accidents and other reasons, and then rush out of the road and fall under the bridge or downhill, causing greater damage. The possibility of casualties generally builds anti-collision barriers on the side or both sides of the road. Concrete anti-collision barriers are one of the most widely used types; Set expansion joints. [0003] The patent document with application number 202022487331.6 discloses a device for cutting expansion joints of bridge guardrails, which includes: a support module installed on the deck of a bridge for supporting slide rails; slide...

AI Technical Summary

Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that the designed device for cutting the expansion joints of bridge guardrails needs to be made for the movement of the cutting module according to the cross-sectional shape of the guardrail. Then adjust the distance between the slide rail and the outer wall of the guardrail to adjust the depth of the cut. However, when facing guardrails with different cross-sectional shapes, it is necessary to design different shapes of slide rails for adaptation in order to control the cut. Depth, which affects the scope of application of the device for cutting expansion joints of bridge guardrails
