Random drawing type width detector for bridge protection safety fence

Abstract

The invention relates to the field of bridge guardrail detection, and concretely relates to a random extraction type width detector for abridge protection safety fence. The detector comprises a supporting frame, a guide rail plate, a guide plate, a safety fence pull-out assembly, a limiting assembly and the like. The guide rail plate is welded to the supporting frame, the guide plate is fixedly connected to one end of the guide rail plate, the safety fence pull-out assembly is fixedly installed on the guide rail plate, and the limiting assembly is arranged on the guide plate. Under the action of a friction strip, a rotating disc is hindered, so that the rotating angle of the rotating disc and the device on the rotating disc is an uncertain factor, the contact positions of an opening rod and a wedge-shaped block are different each time, the opening rod can push the wedge-shaped block and the device on the wedge-shaped block to move in the direction away from the guide rail plate at different time, and a special-shaped limiting rod does not block a pushing plate within uncertain time, so that a drag hook randomly drives one of bridge protective guards to move in the direction away from the guide plate, and the purpose of randomly detecting the width of the bridge protective guards is achieved.

Description

technical field [0001] The invention relates to the field of bridge guardrail detection, in particular to a random extraction type width detection machine for bridge guardrails. Background technique [0002] Guardrails can be seen everywhere in life. Guardrails refer to industrial "guardrails", and bridge guardrails are guardrails set on bridges. The purpose is to reduce the occurrence of accidents such as uncontrolled vehicles breaking through, underpassing, jumping over bridges or entering opposite lanes. , has the function of correctly changing the driving direction of the out-of-control vehicle, and there are various types of bridge guardrails, which have the function of beautifying the bridge building. [0003] After the production and processing of the bridge guardrail is completed, the width of the bridge guardrail needs to be tested. Most factories use the randomly selected and produced bridge guardrails for width detection. Data is inaccurate. SUMMARY OF THE INVE...
