The utility model provides a kind of steel structure building installation positioning device, belong to steel structure building construction technical field.The device structure is ingenious, and it is good to guide, it is convenient to clamp, can be flexibly disassembled, it is convenient for engineering construction use.The electric hoist of the device is fixedly installed on the one side board surface of fixed plate, and a plurality of fixed length's pull cable are fixedly connected on the other side board surface of fixed plate, the free end of each fixed length's pull cable is fixedly bolted screw rod, the drum of electric hoist is wound pull cable, and the free end of pull cable on electric hoist is scattered into multiple strands, and the free end end of each pull cable is fixedly bolted clamping assembly.The device clamps more stable, and the pulling capacity is stronger, and the guiding stability is high, and the alignment accuracy is high, and the assembly construction safety is improved.

The utility model relates to a filtrate bag applied to a dialysis machine and an assembly structure of the filtrate bag and the dialysis machine, and the filtrate bag comprises a filtrate bag body and at least one reinforcing clamp body, the reinforcing clamp body comprises a front reinforcing plate and a rear reinforcing plate, and a first elastic clasp is arranged on the front reinforcing plate. An assembly structure comprises a filtrate bag and a dialysis machine, and a bearing hook with a bearing groove is arranged on the dialysis machine. And the hanging hole is hung on the bearing groove. According to the filtrate bag, the hanging part can be more stably and reliably clamped by the front reinforcing plate and the rear reinforcing plate, so that the structural strength of the hanging part of the filtrate bag can be effectively enhanced, the filtrate bag is difficult to deform and break after being hung for a long time, and the service life can be greatly prolonged. According to the assembly structure, the filtrate bag can be conveniently, rapidly and stably limited, the filtrate bag cannot fall off even if the filtrate bag is greatly scratched, so that the probability of accidents in the dialysis process can be greatly reduced, and the dialysis can be more stably carried out.

The utility model provides a kind of automatic recognition device of degumming and material removal, it is related to silicon wafer production and processing technical field, to solve the existing mechanical arm to execute material removal action, because lack accurate, reliable material removal state identification mechanism, cannot accurately judge whether transfer frame has completely separated from mechanical arm and successfully fallen into degumming pool, this problem can lead to mechanical arm to lift reset, transfer frame is still not correctly separated, and then interfere with the normal progress of subsequent processing process Problem, including main frame;The main frame is rectangular long rod structure.After mechanical arm executes material removal action, before lifting reset, whether transfer frame completely separates from mechanical arm and falls into degumming pool is detected in real time, when identifying that material removal is not successful, can timely feedback to mechanical arm control device, to make mechanical arm execute material removal instruction again, avoid the problem that subsequent processing process is interfered because transfer frame is not correctly separated, the reliability of mechanical arm to execute material removal instruction is significantly improved.

A clamping unit comprises a vertical guide rail which is connected with an oil cylinder through a cross rod, the vertical guide rail is provided with a cross beam which slides along the vertical direction, the bottom of the vertical guide rail is fixedly connected with a supporting plate below the cross beam, the supporting plate is provided with a limiting seat, the limiting seat is provided with a limiting groove, and a clamping unit is arranged on the limiting groove. An arc-shaped fixing clamping plate is arranged on the side, facing the vertical guide rail, of the limiting groove, the inner side face of the arc-shaped fixing clamping plate is flush with the inner wall of the limiting groove, a rectangular hole is formed in the middle of the cross beam, and a vertical plate sliding in the horizontal direction is arranged in the rectangular hole; the side face, facing the vertical guide rail, of the vertical plate is provided with a blocking clamping block matched with the arc-shaped fixing clamping plate to clamp a workpiece, and a water tank is formed in the base. According to the fuel filter sealing detection device, the fuel filter can be stably clamped, the filter outlet of the side outlet is blocked through the blocking clamping block, good airtightness is achieved in the detection process, and then airtightness detection is conducted.
