SUMMERY OF THE UTILITY MODEL
The utility model discloses an overcome prior art roll-type quenching machine and remove the inconvenient problem of frame removal, provide a sheet metal strip roll-type quenching machine and remove frame hoisting device, concrete technical scheme as follows:
the lifting device comprises a hydraulic damper base, a pin shaft, a hydraulic damper cover, a fork head, a lifter screw, a lifter base plate and a spiral lifter, wherein the hydraulic damper base is supported on the ground, the lower end of the hydraulic damper is connected to the hydraulic damper base through the pin shaft, and the hydraulic damper cover is buckled on the upper end of the hydraulic damper; the lower end of the fork head is connected to the hydraulic damper through a pin shaft, the upper end of the fork head is connected with the lower end of a screw rod of the elevator, and the lower side of a bottom plate of the elevator is connected with the upper end of the screw rod of the elevator; the upper side of the elevator bottom plate is connected with a spiral elevator. The spiral lifter is connected with the movable frame of the metal plate strip roller type quenching machine through a universal coupling, and the universal coupling is responsible for transmitting force and moment.
According to the application of the lifting devices, every two lifting devices are connected in series through the connecting shaft, the spiral lifter on each lifting device is connected with the roller type quenching machine moving rack, vertical movement is achieved, the movable beam is lifted, and therefore the distance between the nozzle on the movable beam and the steel plate is adjusted according to the thickness of the steel plate.
The working principle of the utility model is that the hydraulic damper base and the pin roll are lifted and put down by the rotating mode. And then the movable beam is lifted through the screw rod and the screw lifter.
The beneficial effects of the utility model are that, this hoisting device realizes the rising and the decline of walking beam with spiral elevator, adjusts the distance of nozzle and steel sheet on the walking beam according to the thickness of steel sheet, convenient and fast. The lifting device has the advantages of simple mechanism, convenience in maintenance, low failure rate, high roll gap maintaining precision and the like, and can meet the requirement of normal production of the roll quenching machine on high-precision roll gaps.
