Hook-free side plate hanger for suspension chain

Abstract

The invention discloses a provides a hook-free side plate hanger for a suspension chain, which relates to the technical field of car processing equipment, and solves the problem that product quality is affected as appearance is affected by punching in a square tube and even later-stage repair welding and hole plugging is needed while an existing hanger is in use. The hook-free side plate hanger comprises a main body, a pedestal, an inner slot and a clamping plate, wherein the pedestal is arranged on the bottom of the main body; the top of a left rotary plate inside the inner slot is equipped with a rotary rod through a component; the clamping plates are of C-shaped structures, and vertical slots in the tops of the clamping plates are formed in the bottom of the pedestal; and vertical shafts on the tops of the clamping plates are separately mounted on the bottom of a left rotary plate and the bottom of a right rotary plate. Materials such as the square tube are transported by the clamping plates, so that transportation on the square tube by a punching or welding way is reduced; during hanging, the two C-shaped clamping plates move relatively to fit to a rectangular tube, so that a surrounded shape is formed for clamping the rectangular tube, and thus, product quality defects and unnecessary cutting repair-welding operation caused by the original punching way and the original suspended part welding way can be avoided.

Description

technical field [0001] The invention belongs to the technical field of carriage processing equipment, and more specifically relates to a catenary hook-free side plate spreader. Background technique [0002] The van is similar to a cuboid box, consisting of 6 sides, 4 of which are welded together by square tubes and thin corrugated boards. In the corrugated board welding process, electrophoretic primer process, box assembly process and other processes, it is necessary to lift multiple times, and use spreaders to transport materials such as square pipes. [0003] For example, the application number: CN201620323250.3 involves a kind of lifting tooling, which belongs to the field of mechanical equipment lifting machinery. The invention overcomes the problems of the prior art that the operation intensity is high, the danger is high, and the thin-walled cylinder is easily deformed when the cylinder is hoisted. Its structure includes I-shaped steel, I-shaped steel, large side pla...

Problems solved by technology

[0006] In order to solve the above technical problems, the present invention provides a catenary hook-free side plate spreader to solve the problem that when the existing spreader is in use, it is necessary to punch holes on the square tube or weld special hangers, and to punch holes on the square tube. The holes will affect the appearance, and even need to be repaired and plugged in the later stage. The welded hanging parts need to be cut off at the end, and then polished and smoothed. The method of drilling and welding the hanging parts has low production efficiency and affects product quality.
