Description

Technical Field

[0001] The utility model belongs to the technical field of welding equipment, in particular to a hydraulic support side plate welding device. Background Art

[0002] Welding, also known as fusion, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. There are many sources of energy for modern welding, including gas flame, arc, laser, electron beam, friction and ultrasound. In addition to being used in factories, welding can also be performed in a variety of environments, such as outdoors, underwater and in space. No matter where it is, welding may be dangerous to the operator, so appropriate protective measures must be taken when welding. Possible injuries to the human body caused by welding include burns, electric shock, visual impairment, inhalation of toxic gases, excessive ultraviolet radiation, etc.

[0003] The hydraulic support is a structure used to control the mine pressure at the coal mining face. The mine pressure at the mining face acts on the hydraulic support in the form of external load. The hydraulic support includes hydraulic cylinders (columns, jacks), load-bearing structural parts (top beams, shielding beams, bases and movable side guards, etc.), pushing devices, control systems and other auxiliary devices. The side plates of the hydraulic support are arranged on the sides of the top beams, shielding beams or connecting rods to play the role of blocking gangue and preventing backlash. The side plate of the hydraulic support is a plate-like structure with an L-shaped bend. According to its strength requirements, it is necessary to weld multiple reinforcing ribs on the inner side of a plate surface, and according to its functional requirements, it is necessary to weld shaft sleeves on the plate surface to achieve the positioning and installation of some pins.

In addition, welding is a processing method with a poor production environment and high risks, and welding also requires a high level of technical skills for welders. Manual welding will pollute the surrounding environment and affect the health of operators. Utility Model Content
