AI Technical Summary
Existing tank trucks have poor protection for the top and side walls of the tank when they overturn, which can easily lead to damage and leakage. They lack effective protective devices.
A tank protection device for overturning liquid tank trucks was designed, including a tank top protection device and a tank side wall protection device. It adopts a side steel plate and reinforcing ring structure. The side steel plate is corrugated, the top forms a groove-shaped reinforcing part, and the bottom forms an angle-shaped connecting part. The reinforcing ring is a basin-shaped part, which is fixed to the tank by welding.
It improves the protection of the tank top and side walls, reduces production costs, and enhances the strength of the steel plates and reinforcing rings, ensuring that the tank is not easily damaged when it tips over and reducing the risk of leakage.

Abstract
Description
Technical Field
[0001] This utility model relates to a tank protection device for a liquid tanker truck, specifically a tank overturning protection device for a liquid tanker truck. Background Technology
[0002] During transportation, it is inevitable that tank trucks will overturn in the event of a traffic accident. Most current tank trucks have a top protection device on the tank body, which involves installing a fence to protect the safety accessories on the top of the tank. This protection structure is relatively simple and its protective effect is poor, especially in the event of a rollover, as it does not protect the side walls of the tank.
[0003] In order to reduce tank damage, leakage hazards, and economic losses caused by tank trucks overturning and sliding after hitting the ground in traffic accidents, it is necessary to develop a new type of tank truck overturning protection device. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a tank protection device for liquid tank trucks that can provide good protection for the top and side walls of the tank when the vehicle overturns.
[0005] To solve the above-mentioned technical problems, this utility model provides a tank body overturning protection device for liquid tank trucks, including a tank top protection device. The device is characterized by comprising side steel plates disposed on the left and right sides of the tank top and end steel plates disposed at the front and rear ends of the tank top. The bottom of the end steel plates forms an arc-shaped surface corresponding to the outline of the tank top. The ends of the left and right side steel plates are welded to the end steel plates at the front and rear ends. The device also includes a tank sidewall protection device, which consists of reinforcing rings symmetrically welded at intervals to the outer sides of the bottom of the left and right side steel plates. The shape of the reinforcing rings corresponds to the outer outline of the tank.
[0006] As an improvement to this utility model, the bottom ends of the two reinforcing rings are either open or connected as one piece.
[0007] As an improvement of this utility model, the side steel plate is corrugated.
[0008] Furthermore, the top of the side steel plate is bent inward to form a groove-shaped reinforcing part, and the bottom of the side steel plate is bent inward to form an angle-shaped connecting part corresponding to the top contour of the tank.
[0009] Furthermore, the reinforcing ring is a basin-shaped component with a "basin-shaped" cross-section.
[0010] When this utility model is used, the protective device on the top of the tank is welded and fixed to the top of the tank, and the reinforcing rings are welded and fixed to the opposite sides of the tank. This utility model has the following beneficial technical effects: 1. The tank top protection device is composed of side steel plates and end steel plates, which provides better protection for the safety accessories on the top of the tank compared to the traditional fence structure. Furthermore, when the vehicle overturns, the reinforcing rings on both sides can simultaneously provide good protection for the sides of the tank. 2. Depending on the installation position of the tank on the vehicle, the tank portion exposed outside the vehicle can adopt a structure where the bottom ends of the reinforcing rings on both sides are connected as one piece, while the tank portion inside the vehicle can adopt a structure where the bottom ends of the reinforcing rings on both sides have an opening, thus reducing production costs. 3. The side steel plates are corrugated, which enhances their strength. The grooved reinforcing section at the top of the side steel plates further improves their strength, and the angled connecting section at the bottom of the side steel plates enhances their connection strength with the tank. 4. The reinforcing rings are basin-shaped pieces with a "basin" cross-section, further improving their strength. Attached Figure Description

[0020] See Figure 1 - Figure 8 This utility model discloses a tank protection device for a liquid tanker truck that prevents overturning. It includes a tank top protection device 10, which consists of side steel plates 11 on the left and right sides of the top of the tank 9 and end steel plates 12 at the front and rear ends of the top. The bottom of the end steel plates forms an arc-shaped surface 121 corresponding to the outline of the tank top. The ends of the left and right side steel plates are welded to the end steel plates at the front and rear ends. The device also includes a tank sidewall protection device, which consists of reinforcing rings 20 symmetrically welded at intervals to the outer bottom of the left and right side steel plates. The shape of the reinforcing rings corresponds to the outer outline of the tank 9. The bottom ends of the two reinforcing rings 20 have an opening 21 or are connected as a single unit. The side steel plates 11 are corrugated, with the top of the side steel plates bent inwards to form a grooved reinforcing part 111, and the bottom of the side steel plates bent inwards to form an angled connecting part 112 corresponding to the outline of the tank top. The reinforcing ring 20 is a basin-shaped component with a "basin" cross-section. The side steel plate 11, the end steel plate 12, and the reinforcing ring 20 are all made of high-quality carbon steel plate.
