Problems solved by technology

However, the disadvantages of the movable guardrail with the above structure are: 1) each vertical rod needs to be fixedly connected to the fence through the guardrail support, and then the guardrail support is welded on the outside of the fence. The structure of the seat and the welding method is complex, and it is necessary to process and manufacture multiple guardrail supports and weld them to the outside of the fence one by one, so the manufacturing and installation process is very cumbersome; This structure also brings inconvenience to manufacturing and installation, resulting in high production costs; 3) In order to increase the space of the tank roof walkway, the movable guardrail is mostly installed on the outside of the fence, so it has to be The protection to the fence is easy to be damaged, and the tank roof walkway and the movable guardrail span the entire fence, which cannot protect the safety of the staff well, and its safety performance is poor

Abstract

This application relates to the technical field of liquid tank trucks, in particular to a guardrail device on the tank top of a liquid tank car, the structure of which includes a fence, a movable guardrail and a supporting cylinder. The movable guardrail is installed on the two inner sides of the fence in the longitudinal direction. And several vertical rods, the upper end of the vertical rod is connected with the horizontal rod through the first connecting assembly, the lower end of the vertical rod is connected with the vertical rod fixing base through the second connecting component, the vertical rod fixing seat is welded on the inner side of the fence, the first connecting component and the second connecting assembly are both cast aluminum parts; the lower part of the vertical bar is bent toward the swinging direction of the movable guardrail to form a bending angle, and the bending angle is greater than 90 degrees. Compared with the prior art, the guardrail device of the present application has safety High, simple manufacturing and installation process, convenient operation and long service life.

Description

technical field [0001] The present application relates to the technical field of liquid tank trucks, in particular to a guardrail device on the roof of a liquid tank truck. Background technique [0002] Since the top of the tank car is mostly equipped with parts such as charging holes and manholes, operators need to often climb to the top of the tank to load the tank body or perform operations such as cleaning and repairing the parts on the top of the tank. Therefore, in order to ensure the safety of the staff, Guards need to be installed on the roof of the tank. [0003] In the prior art, the protective device mainly includes a fence arranged on the top of the tank, and a movable fence installed on the outside of the fence. For example, a Chinese invention patent application (application number: 200810236767.9) discloses a "guardrail device on the top of a railway tank car". In the plan, the guardrail device includes a movable guardrail and a connecting rod control mechani...
