Tank roof fence device of tank truck

Abstract

The invention relates to the technical field of tank trucks, in particular to a tank roof fence device of a tank truck. The tank roof fence device of the tank truck comprises a fence, wherein the fence is arranged on the tank roof; the fence comprises a front enclosing plate, a back enclosing plate and side enclosing plates which are respectively arranged at both side ends of the front enclosing plate and the back enclosing plate; the bottom of the front enclosing plate and the bottom of the back enclosing plate are welded on the tank roof; the bottoms of the side enclosing plates are bonded to the tank roof; the inner sides of the side enclosing plates are respectively provided with fence support seats and tank body lifting lugs; the bottoms of the fence support seats and the bottoms of the tank body lifting lugs are welded on the tank roof; the tops of the side enclosing plates are provided with buffer rods, and the buffer rods are of sealed or half sealed hollow structures; and the fence device also comprises a guardrail mechanism, and the guardrail mechanism is arranged at one side of the side enclosing plates at least. Compared with the prior art, the tank roof fence device disclosed by the invention has the advantages of high safety performance, light weight, low energy consumption, simple process and cost saving.

Description

technical field [0001] The invention relates to the technical field of tank cars, in particular to a tank roof fence device for tank cars. Background technique [0002] Usually, the top of the tank car is equipped with charging holes and other parts such as manholes for operators to enter and exit the tank for cleaning or maintenance. Operators often need to climb to the top of the tank to load the tank or clean Parts for cleaning, maintenance and other operations. In order to ensure the safety of the staff, a fence device is usually arranged on the tank top. [0003] In the prior art, there are mainly two types of fence devices on the top of the tanker. One is that an air spring is provided in the fence device, and when the staff climbs on the top of the tank body, the fence is manually raised or lowered to ensure personal safety; One is that the fence device is equipped with a hydraulic rod, and the staff directly controls the raising or lowering of the fence device on t...

AI Technical Summary

Problems solved by technology

However, the above-mentioned fencing devices in the prior art have only improved their safety, and have the following defects: 1) the fencing device uses carbon steel, which is the same material as the tank body, as the plate of the enclosure, and due to the density of the carbon steel material Larger, especially for long tank trucks over 10 meters, the weight of the hoarding can reach more than 200KG, so the weight of the hoarding greatly increases the weight of the overall tanker, and the energy consumption is high. Under the load of the tanker, it can be transported The load is reduced and causes serious wear to the tires of tank trucks; 2) The fencing device of the prior art mainly adopts welding process, first the carbon steel hoarding is bent into an inverted U shape, and then the hoarding is welded to the top of the tank body

For carbon steel plates, the welding process is complicated and time-consuming, and an additional crane is required to send the coaming to the tank roof, which greatly increases the production cost
