The utility model provides a chain guide of a loop chain elevator, and belongs to the technical field of loop chain elevators. The technical problem that an existing chain guide vibrates is solved. The chain guide of the loop chain elevator comprises an integrally-formed chain guide body, the chain guide body comprises a round part and a square part, the width of the square part is larger than that of the round part, and a mounting hole and a chain guide channel are formed in the chain guide body. The guide chain channel comprises an arc channel, a first inlet-outlet channel and a second inlet-outlet channel, the first inlet-outlet channel and the second inlet-outlet channel are in smooth direct connection with the two ends of the arc channel, the mounting hole and the arc channel are located in the circular part and are coaxially arranged, and the first inlet-outlet channel and the second inlet-outlet channel are located in the square part. The positioning cylinder is arranged on the upper portion of the mounting hole, a guide protruding block protrudes from the lower end, located on the first inlet-outlet channel, of the square part, and a chain wheel is arranged in the mounting hole. The chain guide has the advantage of being capable of reducing vibration and abrasion of the chain guide.

The utility model discloses a pipe production offline quality detection device, which belongs to the technical field of pipe detection and comprises an equipment bottom plate, a pair of hexagonal mounting frames are arranged on one side of the top of the equipment bottom plate, and adjustable limiting components are arranged on the two hexagonal mounting frames in a circumferential array manner. Fixing seats distributed in a circumferential array mode are installed between the two hexagonal installation frames, visual cameras are fixedly installed on the fixing seats, the bottoms of the two hexagonal installation frames are each fixedly connected with a pair of supporting rods, and one end of each supporting rod is fixed to the top of the equipment bottom plate. A lifting bearing assembly is connected to the position, located on one side of the hexagonal mounting frame, of the top of the equipment bottom plate, a to-be-detected pipe is arranged on the lifting bearing assembly, and one end of the to-be-detected pipe is arranged in the adjustable limiting assembly in a penetrating mode. And meanwhile, the pipes with different diameters can be conveyed in a limited mode, and practicability is high.
