Anti-explosion crane hook sleeve

Abstract

The invention discloses an anti-explosion crane hook sleeve which comprises a sleeve body. The sleeve body is formed by knitting flexible non-metallic materials to be latticed in a staggered manner. The sleeve body serves as a non-metallic knitted anti-explosion layer of a hook body, the sleeve body and the hook body are fixed together through an adhesive, and a closed containing cavity defined by the sleeve body matches the hook body in shape. The lower end of the sleeve body is sealed, the upper end of the sleeve body is open and serves as a sleeve opening end, and a sleeve opening fixing device is arranged at the sleeve opening end. The anti-explosion crane hook sleeve is specially designed according to the anti-explosion requirement of a crane, flammable and combustible accidents are effectively avoided, and the anti-explosion crane hook sleeve is convenient to replace, economical, durable and good in anti-explosion performance. It is avoided that the material of the hook is changed due to welding, and the original performance of the material of the hook is guaranteed. If the hook sleeve is seriously abraded and needs to be replaced, the hook sleeve can be easily replaced simply by loosening a non-metallic belt without replacing the hook together, and the hook can be recycled.

Description

technical field [0001] The invention relates to a lifting accessory, in particular to an explosion-proof crane hook cover. Background technique [0002] The traditional explosion-proof crane hook, in order to prevent the crane hook from colliding with the workpiece to generate sparks and cause the explosion or combustion of flammable and explosive gases in the surrounding environment, the surface of the crane hook is generally covered with stainless steel skin. However, the stainless steel leather part It needs to be welded on the surface of the hook by electric welding, which will have the following problems during use. First, the material of the hook where welding is easy to change, which affects the performance of the hook. Second, the stainless steel skin cannot be replaced after it is worn out. Replacing a whole hook causes a serious waste of resources and does not utilize the recycling of resources. Contents of the invention [0003] The purpose of the present inven...

Problems solved by technology

[0002] For traditional explosion-proof crane hooks, in order to prevent the crane hook from colliding with the workpiece to generate sparks and cause explosion or combustion of flammable and explosive gases in the surrounding environment, stainless steel skin is usually wrapped on the surface of the crane hook. However, the stainless steel leather parts It needs to be welded on the surface of the hook by electric welding, which will have the following problems during use. First, the material of the hook where welding is easy to change, which affects the performance of the hook. Second, the stainless steel skin cannot be replaced after it is worn out. Replacing a whole hook will cause a serious waste of resources, and the recycling of resources will not be used
