Problems solved by technology

[0005] 1. Plastic is combustible, and there are potential fire safety hazards;
[0006] 2. Plastic products are easy to age, and their strength is reduced. Expired plastic stoppers cannot be used. It is difficult to grasp the inventory stock of the railway department, and the loss of scrapping is relatively large.
[0007] 3. The structural design of the product is not good, the force analysis is unscientific, the size ratio and the location of the reinforcement are not very reasonable, resulting in a large product weight, a lot of materials, complex molds, many processes, and a long manufacturing cycle

Abstract

The invention discloses a special wheel stopper for stopping wheeled cargo. The wheel stopper is scientific in material formula, reasonable in structure, safe and reliable to use and easy to store; plastic is used for replacing wood, so that deforestation is reduced and environment friendliness is achieved; the wheel stopper has significant social benefit, environmental protection benefit and economic benefit; mechanical properties of the product completely meet the ministerial standards of the former Ministry of Railways.

Description

technical field [0001] The invention belongs to the railway freight loading reinforcement technology, and relates to cargo loading reinforcement equipment, specifically, a wheel chock specially used for covering wheeled cargo. Background technique [0002] When transporting goods by railway vehicles, the goods must be reinforced after loading. For cylindrical goods, it is covered with a triangular prism-shaped device, which is called a triangle block, and its cross-sectional profile is an isosceles triangle; for wheeled goods (such as automobiles, engineering vehicles), the wheel radius is larger, The triangular chock is used to cover, and the wheel chock is used to cover the wheel with a small radius. The so-called wheel chock is also a triangular prism-shaped device. The only difference is that there is an arc consistent with the outline of the wheel shaped groove. When the reinforcing equipment is used, it is anchored on the cargo support. [0003] The above-mentioned ...
