Supporting device for preventing head of person from being clamped during turnover of a guardrail of a truck

Abstract

The invention provides a supporting device for preventing the head of a person from being clamped during turnover of a guardrail of a truck, relates to the technical field of truck protection, and aims to solve the problems that an existing supporting device for preventing the head of a human body from being clamped during turnover of a guardrail is not convenient enough to mount during use, cannot be disassembled conveniently when not used, and cannot give out prompt sound when a guardrail is turned over. The supporting device comprises a main body and a mounting piece; the main body is of arectangular plate-shaped structure, and the two sides of the main body are of inclined structures; the bottoms of fixing plates are fixedly connected to the two sides of the top end of the main body.After the main body is mounted, the mounting head of the mounting piece can be controlled to be embedded into a slot, so that the mounting piece can be stably mounted and fixed; and when an ejector rod turns along with the guardrail, the ejector rod drives a push rod to turn at the top end of the mounting piece, so that the push rod can be in contact with an air bag of the air horn, and the push rod can continuously compress the air bag, and the air horn can continuously give out a prompt sound.

Description

technical field [0001] The invention belongs to the technical field of truck protection, and more specifically relates to a support device for avoiding pinching the head of a bystander when the guardrail of a large truck turns over. Background technique [0002] When a large truck is loading and unloading goods, it is usually necessary to turn over and open the guardrail. If there is someone next to the guardrail, it is easy to pinch the head of the human body and cause damage. [0003] For example, the application number: CN201410807640.3 relates to a flip-type car side guardrail, the upper guardrail including the side guardrail is firmly and reliably installed on the frame of the vehicle, and the lower guardrail is connected to the upper guardrail through a hinge rod. One end of the hydraulic cylinder is hinged on the vehicle frame, and the other end is hinged on the lower guardrail. The expansion and contraction control valve of the hydraulic cylinder is controlled by th...

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a support device for preventing the head of a person from being caught when the guardrail of a large truck is overturned, so as to solve the problem that the existing support device for preventing the head of a human body from being caught when the guardrail is overturned needs to be installed. It is not convenient enough, and it cannot be easily disassembled when not in use. It cannot automatically send out a sound when the guardrail is turned over and opened, and the existing support device that prevents the human head from being caught when the guardrail is turned over cannot be used conveniently. The air brace buffers the impact force, and the gas brace cannot affect the closing speed when the guardrail is flipped and closed, and the buffer distance of the gas brace cannot be adjusted
