A roll removal device

Abstract

The invention provides a roller detaching device which comprises a base, a motor, an electric cabinet, clamping plates, a clamping base, a support, a pull rod, a sizing block, stop iron, a clamping hoop, an oil tank, a gear pump, a hydraulic cylinder, an integrated block, an oil filter and a pressure gauge. Clamping grooves are formed in the clamping plates on two sides of the base and the upper end of the clamping base, the two ends of the pull rod are fixed in the clamping grooves through wedges, the hydraulic tank is fixed on the support on the inner sides of the clamping plates, the hydraulic tank is connected with the gear pump, the gear pump and the motor are fixed on the oil tank, the electric cabinet is arranged on the clamping plates, the electric cabinet is connected with the motor and the integrated block, and the motor is connected with the gear pump through a belt. A bearing seat to be detached is hung on the sizing block, namely the roller or a conveying roller shaft can be ejected out from the bearing seat through a hydraulic cylinder piston rod. By means of the device, the roller and the bearing seat or the gear and the roller shaft can be detached and separated fast, detaching time is shortened, labor intensity is reduced, the detached part is prevented from being damaged, spare part consumption is reduced, safety accidents are avoided, and device operation rate is improved.

Description

technical field [0001] The invention belongs to the field of mechanical equipment, in particular to a roller shaft dismounting device for rollers or conveying roller tables. Background technique [0002] In the continuous rolling production line of the hot rolling mill, it is very difficult to replace the rolls or the conveying roller table. The roller table bearing needs to disassemble the gear first. Since the gear is installed in a hot-loading method, it is used to match the conveying roller shaft. If the gear is cut off, it will increase the consumption of spare parts. After being heated by gas welding, the disassembly of the gear with a sledgehammer is not only time-consuming and laborious, but also poses a great safety hazard. Especially for the disassembly of heavy rolls and bearing housings, it is even more difficult. It is difficult to lift heavy parts by crane, it is not easy to fix, and it requires a lot of force to disassemble. It is difficult to disassemble with...

[0002] In the continuous rolling production line of the hot rolling mill, it is very difficult to replace the rolls or the conveying roller table. The roller table bearing needs to disassemble the gear first. Since the gear is installed in a hot-loading method, it is used to match the conveying roller shaft. If the gear is cut off, it will increase the consumption of spare parts. After being heated by gas welding, the disassembly of the gear with a sledgehammer is not only time-consuming and laborious, but also poses a great safety hazard.

Especially for the disassembly of heavy rolls and bearing housings, it is even more difficult. It is difficult to lift heavy parts by crane, it is not easy to fix, and it requires a lot of force to disassemble. It is difficult to disassemble without using powerful tools. , due to the low efficiency of disassembly, it seriously affects the smooth progress of production
