Description

Technical Field

[0001] This utility model relates to a support structure for the tank body of a semi-trailer tanker, belonging to the technical field of semi-trailer tank body support structure. Background Technology

[0002] During transport, the tank body of a semi-trailer tanker truck needs to be secured to the semi-trailer using its supporting structure. However, the tank body is often welded to this structure. When the vehicle travels on bumps, the supporting structure is prone to localized stress concentration, which can lead to damage over time. Furthermore, the tank body lacks shock absorption measures, affecting its lifespan. Additionally, the tank body's supporting structure is mostly made of steel and is heavy. In Europe, with increasing competition in the road transport industry, transport companies are striving to find solutions to increase carrying capacity and reduce freight costs.

[0003] Existing tank trucks primarily use steel or aluminum alloy for their tank support structures, which are typically welded or secured to the vehicle's underframe with metal straps. When the vehicle travels on bumpy roads, the support structure is prone to localized stress concentration, which can lead to damage over time. Furthermore, the tanks lack shock absorption measures, further impacting their lifespan. These issues result in the following drawbacks:

[0004] 1. Unable to achieve rapid mass production.

[0005] 2. Short service life, poor load-bearing capacity, and metal structure is prone to oxidation and rust.

[0006] 3. Heavier: Metal structures are heavier than composite material structures, especially compared to metal tanks.

[0007] 4. Complexity, and the welded structure is prone to welding stress.

[0008] The problem to be solved is how to provide a tank support structure that can adapt to the complex road conditions encountered by vehicles during transportation and is also lightweight. Utility Model Content

[0012] The width of the composite connecting block is smaller than the width of the composite support plate 1; fixing straps are provided on both sides of the composite connecting block, and the fixing straps are wrapped around the outside of the tank.

[0013] Based on the above scheme and as a preferred embodiment of the above scheme: the lightweight filler is a foamed material or balsa wood.

[0014] Based on the above scheme and as a preferred embodiment of the above scheme: the composite material support plate and the composite material connecting block are made of composite materials, which are carbon fiber composite materials, glass fiber composite materials or carbon fiber / glass fiber hybrid composite materials.

[0015] Based on the above solution and as a preferred solution: a shock-absorbing pad is provided between the composite connecting block and the vehicle body.

[0016] Based on the above solution and as a preferred embodiment of the above solution: the shock-absorbing pad is made of rubber or polyurethane.

[0017] The beneficial effects of this utility model are as follows: The tank support structure of the semi-trailer involved in this utility model adopts a composite material support plate integrally formed with the tank body, which reduces the effective weight, allows for the transport of more products, has better heat insulation, and can be produced using molds, enabling rapid mass production and high production efficiency. Furthermore, the absence of welding stress in metals increases reliability. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] Combination Figures 1 to 7 This embodiment will be described in detail below. The supporting structure for a semi-trailer tanker body according to this utility model includes a composite support plate 1 fixedly connected to the outer surface of the tank body 10, and a composite connecting block 2 fixedly mounted on the composite support plate 1; a receiving space is formed between the composite connecting block 2 and the composite support plate 1, which is filled with a lightweight filler 3; a metal connector 4 is pre-embedded in the receiving space, and the metal connector 4 is provided with a threaded connection hole for fixed connection with the semi-trailer tanker body 20.

[0028] The tank body 10 and the supporting structure involved in this utility model are integrally cured and molded. The composite material support plate 1 and the composite material connecting block 2 are made of composite materials, namely carbon fiber composite materials, glass fiber composite materials, or carbon fiber / glass fiber hybrid composite materials. In this embodiment, carbon fiber composite materials are selected. Specifically, the tank body 10 is made of carbon fiber yarn wound according to a set pattern, while the supporting structure is made of carbon fiber fabric. A certain number of supporting structures are distributed on the tank body 10, and the shape of the composite material support plate 1 matches the shape of the tank body 10. Specifically, in this utility model, the structure of the composite material support plate 1 is arc-shaped. The weight of the conventionally used metal material support structure is at least 110 kg, while the weight of the support structure made of the composite material is only 34 kg. Moreover, at least 6 or more support structures are required on one tank body 10, which can reduce the weight by at least 456 kg.

[0029] Both the tank body 10 and the supporting structure are made of composite materials and are integrally molded using a mold, which enables mass production and diversified design of products, ensuring controllable product quality. The composite fabric and design can adapt to various complex shapes and have a better appearance.

[0030] The width of the composite connecting block 2 is smaller than the width of the composite support plate 1; fixing straps 5 are provided on both sides of the composite connecting block 2, and the fixing straps 5 are wrapped around the outside of the tank body 10. The fixing straps 5 are also made of composite material, specifically carbon fiber webbing.

[0031] Furthermore, the lightweight filler 3 is a foamed material or balsa wood, but other lightweight materials can also be selected. In this embodiment, it can be a foamed material, such as polyurethane foam or EVA foam.

[0032] A typical tank body has at least six supporting structures. The composite material tank support structure is integrated with the tank body and has a rational design, preventing localized stress concentration during vehicle travel. A shock-absorbing pad 6 is installed between the composite material connecting block 2 and the vehicle body 20 to absorb vibrations and extend its service life.

[0033] Furthermore, the shock-absorbing pad 6 can be made of rubber or polyurethane, or other elastic shock-absorbing materials.
