The invention discloses a safe falling-prevention device for a welding operating machine lifting mechanism. The safe falling-prevention device comprises a first support, a second support and a fixing plate arranged between the first support and the second support. The fixing plate is provided with a groove opening and is connected with a pawl through a mandrel in a rotating mode. The first support is provided with a blind hole in the horizontal direction. The blind hole is internally provided with a jacking block in a movable mode. A spring is arranged between the jacking block and the bottom of the blind hole. One end of the lower portion of the pawl is provided with a protruding block for clamping the jacking block, and the other end of the lower portion of the pawl is provided with a stop pawl matched with a ratchet. The upper portion of the pawl is provided with an installing block. The installing block is provided with an installing hole for being connected with a chain. By means of the safe falling-prevention device, accidents of chain breakage and self falling of heavy objects caused by chain aging or external force can be prevented, device safety and personal safety of operating personnel can be effectively guaranteed, and the safe falling-prevention device has the advantages of being simple and compact in structure, flexible to operate, safe and reliable to lock, durable and convenient and fast to assemble and disassemble.
Description
technical field [0001] The invention relates to a welding manipulator, in particular to a safety fall prevention device for a lifting mechanism of the welding manipulator. Background technique [0002] At present, when welding large-diameter workpieces such as wind power towers and boilers, the welding torch needs to be raised to the top of the workpiece. The most widely used equipment is the welding manipulator. Before welding, the welding torch is raised to the required height by the lifting mechanism on the top of the welding manipulator, and then the welding work starts. However, most of the lifting mechanisms of welding manipulators on the market adopt the form of chains or gear chains; at present, domestic manufacturers mostly adopt the form of double chains, which do not have anti-falling devices, and there are great potential safety hazards. Once the double chains break at the same time, It will cause major production accidents; some manufacturers adopt the lifting ...
