Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, and particularly relates to a foldable fire-catching hopper. Background Art

[0002] During the on-site construction of steel structure columns, steel keels of exterior curtain walls, etc., there is a large amount of welding work. Since a large number of high-temperature welding slag will splash everywhere during the welding process, improper handling is likely to cause damage to the surface paint of the steel structure, and the high-temperature welding slag is also likely to fall and cause a fire. In order to avoid this situation, it is usually necessary to tie and fix the fire-catching hopper to the steel structure with a rope below the welding position to collect and process the high-temperature welding slag, and avoid accidents or damage to objects caused by the splashing of high-temperature welding slag.

[0003] Due to the fixed shape of the traditional fire-catching hopper, it occupies a large space and is not conducive to the carrying of construction workers during high-altitude operations. Therefore, a foldable fire-catching hopper has emerged on the market at present. For example, a foldable and portable fire-catching hopper disclosed in the utility model patent with the publication date of October 22, 2021 and the publication number of CN214444050U, including a fire-catching hopper body, is characterized in that: the fire-catching hopper body includes a front side plate, a rear side plate, a left side plate, a right side plate and a bottom plate, the left and right side plates are hinged to the front and rear side plates, both sides of the bottom plate are hinged to the front and rear side plates, the left side plate, the right side plate and the bottom plate are each composed of two baffle plates hinged together, and the hinge axes of the left side plate, the right side plate and the bottom plate are on the same straight line or parallel to each other. After the fire-catching hopper body is unfolded, it forms a funnel-shaped fire-catching hopper body with an open top and a sealed bottom. Although this fire-catching hopper can be folded when not in use and assembled when needed, when assembling, its front side plate and rear side plate need to be locked to the hinges on the left side plate and the right side plate respectively by pins or screws to complete the assembly. Similarly, when disassembling, the pins or screws need to be removed before folding can be carried out. Therefore, this fire-catching hopper needs to add additional fixing accessories to complete the assembly, is inconvenient to assemble during high-altitude operations, and there is a risk that the fixing accessories are likely to fall off, and it is also inconvenient to carry.
