Description

Technical Field

[0001] This utility model relates to the field of hazardous chemical transport vehicle technology, specifically to an energy-absorbing frame at the rear of a storage tank in a hazardous chemical transport vehicle. Background Technology

[0002] Currently, with the rapid development of the logistics industry and the increasing number of highways, the transportation of hazardous chemicals mainly uses tank trucks, which has become one of the main modes of land transportation. In order to prevent serious rear-end collision accidents, anti-collision devices are installed at the rear of the tanks. At present, most anti-collision devices use rigid objects, which result in extremely large impact forces when they collide, which can easily lead to the failure of protection, causing the tank to rupture, hazardous chemicals to leak, pollute the environment, and endanger people's lives.

[0003] A search revealed that patent application CN206278049U discloses a rear protection device for a hazardous chemical liquid transport vehicle. The device consists of a vehicle frame assembly, a first spring, a rubber plate, a second spring, a first support arm, a support plate, a second support arm, a first spring guide cylinder, a first guide post, a second spring guide cylinder, and a second guide post. The rubber plate is fixedly mounted on the support plate with screws. One end of the first support arm and the second support arm are respectively fixedly welded to the left and right sides of the support plate. This device can prevent vehicles from going under the rear of the truck and reduce the occurrence of more serious traffic accidents.

[0004] However, due to the rubber plate and support plate, the protective device has poor buffering and shock absorption effect when a vehicle is rear-ended, resulting in poor performance. At the same time, due to the low strength of the rubber plate, the impact force during a rear-end collision is large, and the protective device is prone to deformation, resulting in low strength and stability of the protective device, thus affecting the protective effect.

[0005] Therefore, we propose an energy-absorbing frame for the rear of a hazardous chemical transport vehicle storage tank. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an energy-absorbing frame for the rear of a hazardous chemical transport vehicle storage tank, which solves the problems of poor buffering and shock absorption and low stability of existing devices.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: an energy-absorbing frame for the rear of a storage tank of a hazardous chemical transport vehicle, including a base, wherein the tank body is mounted on the top surface of the base;

[0008] The top surface of the base is fixedly equipped with a fixed frame that is positioned opposite each other and has a matching specification. The top surface of the base is fixedly equipped with two sets of fixed blocks that are positioned opposite each other. The right side of the fixed frame is equipped with a protective frame that has a matching specification. The bottom surface of the protective frame is fixedly equipped with a rotating cylinder that has a matching specification. The rotating cylinder is connected to the fixed block through a rotating shaft. The outer side of the fixed block has a slot that extends into the rotating shaft. The slot is equipped with a locking pin that has a matching specification. The right side of the fixed frame is fixedly equipped with six sets of shock-absorbing springs that are positioned opposite each other. The shock-absorbing springs are equipped with dampers that have a matching specification. The right side of the shock-absorbing springs is fixedly equipped with a support plate that has a matching specification. The right side of the support plate is in contact with the protective frame.

[0009] Two sets of intersecting and compatible reinforcing rods are fixedly installed on the inner wall of the protective frame. The front side of the fixed frame has through holes with opposite positions. Reinforcing anchor rods with compatible specifications are installed in the holes. Nuts with compatible specifications are threaded onto the outer wall of the reinforcing anchor rods. Two sets of support rods with opposite positions are fixedly installed between the left side of the fixed frame and the base.

[0010] Preferably, a cushioning pad of the same specifications is fixedly installed on the right side of the base, thereby improving the cushioning performance of the right side of the base.

[0011] Preferably, the right side of the reinforcing bar is fitted with a reflective strip of the appropriate size, which can alert vehicles behind.

[0012] Preferably, a rubber layer of matching specifications is fixedly installed on the outer wall of the support plate, which can improve the cushioning performance of the support plate.

[0013] Preferably, the reinforcing anchor rod and the support rod are made of steel, which can improve their strength and prevent breakage.

[0014] Preferably, the rotating drum and the rotating shaft are made of alloy materials, which can improve their strength and extend their service life.

[0015] 1. This energy-absorbing frame for the rear of a hazardous chemical transport vehicle storage tank, through the setting of a fixed frame, a protective frame and shock-absorbing springs, rotates the protective frame to a vertical state through a rotating drum and a rotating shaft, with the right side of the support plate contacting the protective frame, and then locking pins to limit and fix the rotating drum. When the rear of the vehicle is impacted, the shock-absorbing springs and dampers can absorb shock and buffer the protective frame, improving its shock absorption effect and usage effect.

[0016] 2. Simultaneously, by setting up reinforcing rods and reinforcing anchors, the reinforcing rods can improve the overall strength and impact resistance of the protective frame, while the reinforcing anchors and support rods can improve the stability and strength of the fixed frame, thereby improving the overall impact resistance and stability of the device and enhancing its performance.
