Abstract
Description
Technical Field
[0001] This utility model relates to the field of roll repair, and in particular to a special weld overlay separation device for roll repair. Background Technology
[0002] Roll repair is a technique that uses welding to clad alloy materials with certain properties onto the surface of a roll in order to restore or improve its performance and lifespan. The purpose of welding is not to connect workpieces, but to modify the surface of the roll to obtain a cladding layer with special properties such as wear resistance, heat resistance, and corrosion resistance, or to repair dimensional deficiencies caused by wear or processing errors.
[0003] Currently, during roll repair, workers often use auxiliary equipment to improve the efficiency of the repair work. However, most of the existing auxiliary equipment cannot properly fix the rolls, which can affect the personal safety of workers during the roll repair process. To address this issue, we propose a special weld overlay separation device for roll repair. Utility Model Content
[0004] The purpose of this invention is to provide a special weld overlay separation device for roll repair, so as to solve the problems mentioned in the background art.

[0006] A special weld overlay separation device for roll repair includes a main frame, a support column fixedly connected to the outer surface of the main frame, a set of auxiliary grooves opened on the outer surface of the support column, an auxiliary block slidably connected inside each auxiliary groove, a connecting block fixedly connected to the side of each auxiliary block away from the auxiliary groove, a set of hydraulic pushing devices fixedly connected to the outer surface of the support column, a force-bearing block fixedly connected to the output end of each hydraulic pushing device, the outer surface of each force-bearing block fixedly connected to the outer surface of the connecting block, and a clamping arm fixedly connected to the outer surface of each force-bearing block.
[0007] In a further embodiment, a set of mounting grooves are provided on the outer surface of the main frame, and a support rod is fixedly connected to the inner sidewall of each mounting groove, and an auxiliary rotating wheel is provided on the outer surface of each support rod.
[0008] In a further embodiment, a set of slide rails is provided on the outer surface of the main frame, and each slide rail is slidably connected to a pulley, with the inner rings of the two pulleys being fixedly connected to a rotating shaft.
[0009] In a further embodiment, a connector is fixedly connected to the outer surface of the rotating shaft, and a placement plate is fixedly connected to the outer surface of the connector.
[0010] In a further embodiment, a support plate is fixedly connected to the outer surface of the main frame, a first bearing is fixedly embedded inside the support plate, and a second bearing is fixedly embedded on the outer surface of the main frame.
[0011] In a further embodiment, a rotary motor is fixedly connected to the outer surface of the main frame, and a gathering rod is fixedly connected to the output end of the rotary motor. The outer surface of the gathering rod is fixedly connected to the inner ring of the first bearing, and the outer surface of the gathering rod is fixedly connected to the inner ring of the second bearing.
[0012] In a further embodiment, a steel wire rope is fixedly connected to the outer surface of the gathering rod, and the end of the steel wire rope away from the gathering rod is fixedly connected to the outer surface of the connector. A controller is fixedly connected to the outer surface of the main frame.
[0013] In a further embodiment, a force-bearing column is fixedly connected to the outer surface of the main frame, and a device groove is formed on the outer surface of the force-bearing column. A snap-fit component is slidably connected inside the device groove.
[0014] In a further embodiment, a transmission component is fixedly connected to the outer surface of the snap-fit assembly, an electric push rod is fixedly connected to the outer surface of the snap-fit assembly, and a welding machine is fixedly connected to the output end of the electric push rod.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] This device provides ample space for the rolls using a placement plate with a corresponding curvature to effectively prevent the rolls from rolling. Simultaneously, through auxiliary blocks, auxiliary grooves, connecting blocks, clamping arms, force-bearing blocks, and a hydraulic pusher, the hydraulic pusher provides the force-bearing blocks with the power to move. This allows the clamping arms to firmly secure the rolls placed on the placement plate as the force-bearing blocks slide within the auxiliary groove, connected to the connecting blocks. This effectively solves the problem that most existing auxiliary equipment cannot properly secure the rolls, thus posing a safety hazard to workers during roll repair. Attached Figure Description

[0029] The working principle of this utility model is as follows:
[0030] When using the equipment, the operator first needs to place the roll to be repaired onto the placement plate 13. Then, the controller 4 starts the rotary motor 18 to provide rotational power to the gathering rod 15. The gathering rod 15 gathers the steel wire rope 19 to provide traction force to the connector 20. With the cooperation of the pulley 2 and the auxiliary rotating wheel 25, the placement plate 13 is moved to the appropriate position. Then, the operator uses the controller 4 to firmly fix the roller placed on the placement plate 13 with the force of the hydraulic push device 23 using the clamping arm 22. Finally, the operator uses the controller 4 to operate the transmission component 8 and the electric push rod 10 to adjust the welding machine 11 to the appropriate position with the cooperation of the clamping component 9 to repair and weld the roller.
