Problems solved by technology

[0004] However, there is currently a lack of special bending construction equipment for corrugated beam steel guardrails. In the existing construction, the corrugated beam steel guardrails can only be bent manually, which not only consumes a lot of energy, requires many operators, but also has certain dangers. Simple tools such as levers are used to operate, which is difficult and dangerous
The existing installation equipment and installation methods cannot move the installation hole of the corrugated beam steel guardrail horizontally to the bracket at the front end of the column accurately, and can only move the corrugated beam steel guardrail roughly to the front end of the column. At this time, the corrugated beam steel guardrail There is a vertical distance between the installation center line and the installation hole on the bracket, which is difficult to connect, requires manual adjustments many times, complicated operation, and low installation efficiency

A circle of annular supporting ring is fixed to the bottom end of the inserting rod, the connecting frame is vertically fixed to the rear portion of the supporting ring, the two adjustable fastening assemblies are connected to the front end of the connecting frame, one adjustable fastening assembly is located at the top of the front end of the connecting frame, and the other adjustable fastening assembly is located at the bottom of the front end of the connecting frame.The installation center line of a corrugated beam steel guardrail can be accurately in butt joint with installation holes in a bracket in the vertical direction, the installation efficiency is improved, and the equipment is convenient to use and carry.

Description

technical field [0001] The invention relates to the technical field of construction of a corrugated beam steel guardrail, in particular to an auxiliary installation device and an installation method for a corrugated beam steel guardrail in a curved road section. Background technique [0002] The road safety guardrail is a longitudinal energy-absorbing mechanism that absorbs collision energy through self-deformation or vehicle climbing, thereby changing the form and direction of the vehicle, preventing the vehicle from driving out of the driving lane or entering the opposite lane, and can reduce the degree of driver injury and protect the road. side objects. Wave beam steel guardrail is currently the most widely used form of safety guardrail, which includes two wave beam steel guardrails and three wave beam steel guardrails. [0003] There will inevitably be curved road sections in the construction of highway safety guardrails, for example, as shown in the attached manual f...
