Problems solved by technology

When the strip steel passes through the specific roller configuration, the strip shape can be corrected through the combination of bending and stretching. At the same time, it can remove the thicker iron oxide layer on the surface of the strip steel and speed up the pickling speed. After a long time of use, the work roll will stick to the roll surface At the same time, it is worn by high-speed strip steel, which seriously affects the straightening accuracy of work rolls
[0003] When changing the roll system, it can only be changed manually by workers. At the same time, when changing the upper roll system, due to the deflection angle between the working roll system and the roll box, the worker needs to adjust the roll changing angle in advance, and lift and change the rolls one by one, which is time-consuming and laborious. Failure to replace the roll system in time will reduce the working efficiency of the scale breaker and reduce the service life of the working rolls

Embodiment 1

[0041] This embodiment provides a roll changing trolley for a phosphorus breaking machine, comprising a vehicle frame 1, wheels are arranged under the vehicle frame 1, a moving seat, an angle adjustment mechanism and a driving device are arranged on the vehicle frame 1, and the moving The seat is connected with the driving device, and the angle adjustment mechanism is set on one side of the moving seat, and the angle adjusting mechanism is used to guide the moving seat after adjusting the angle of the roller system of the phosphorus breaker, and the moving seat is drawn out by the driving device. Old rolls and replacement with new rolls.

[0042] Use process:

[0043] After the roll changing trolley of the phosphorus breaker moves to the roll change position of the phosphorus breaker through the wheels, the angle adjustment mechanism matches the angle adjustment of the roll system of the phosphorus breaker, and then the driving device drives the moving seat to catch the old ro...

Embodiment 2

[0046]On the basis of Embodiment 1, this embodiment provides a roll changing trolley for a phosphorus breaker, the driving device includes a lead screw 4, a torque limiter 5 and a reduction motor 6, and the lead screw 4 is equipped with a nut, The moving seat is fixedly connected with the nut, the reduction motor 6 is arranged at one end of the lead screw 4, and the torque limiter 5 is arranged on the rotation shaft of the reduction motor 6;

[0047] A proximity switch 7 is installed on the vehicle frame 1, and the proximity switch 7 is connected with the torque limiter 5 through an electric signal.

[0048] The reduction motor 6 starts, drives the lead screw 4 to rotate, and the nut drives the moving seat to reciprocate in a straight line along the lead screw 4, approaching or principle roller changing position. Roll position), the proximity switch 7 senses, and transmits the signal to the torque limiter 5, and the torque limiter 5 is opened to disengage the geared motor 6 fr...

Embodiment 3

[0050] On the basis of Embodiment 1, this embodiment provides a roll changing trolley for a phosphorus breaker, and a guide rail 1 is also provided on the frame 1, and the guide rail 1 is arranged on one side of the driving device. A guide wheel is provided on one side, and the moving seat is slidably connected with the guide rail through the guide wheel.

[0051] When the moving seat moves under the drive of the driving device, the guide wheel moves along the guide rail to guide the movement of the moving seat.

Abstract

The invention provides a roller changing trolley, system and method for a scale breaker. The trolley comprises a frame, wheels are arranged under the frame, a moving seat, an angle adjusting mechanism and a driving device are arranged on the frame, the moving seat is connected to the driving device, the angle adjusting mechanism is arranged on one side of the moving seat, the angle adjusting mechanism is used for conducting angle guiding on the moving seat after matching angle adjustment of a scale breaker roller system, and the moving seat pulls out an old roller system and replaces the same with a new roller system through the driving device. The roll changing or mounting angle of the moving seat matches the angle adjustment of the scale breaker roller system through the angle adjusting device, so that the roll changing angle is prevented from being repeatedly adjusted and confirmed by naked eyes of an artificial user, and the roll changing efficiency is improved. When an upper roller is replaced, the angle is adjusted through a worm and gear device, it is guaranteed that a deflection angle of a clamping groove of a rotating shaft of the moving seat is consistent with the angle of an upper roller system of the scale breaker and is fixed, and the roller replacing efficiency is improved. By arranging a first upper guide rail and a first lower guide rail simultaneously, the upper roller and a lower roller can be replaced simultaneously, and the roller replacing efficiency is further improved.

Description

technical field [0001] The invention belongs to the technical field of metal surface treatment equipment, and in particular relates to a roll changing trolley, system and method for a phosphorus breaking machine. Background technique [0002] The phosphorus breaker is widely used in the pickling line and can effectively improve the quality of pickling. When the strip steel passes through the specific roller configuration, the strip shape can be corrected through the combination of bending and stretching. At the same time, it can remove the thicker iron oxide layer on the surface of the strip steel and speed up the pickling speed. After a long time of use, the work roll will stick to the roll surface Oil stains and the wear of the high-speed strip steel will seriously affect the straightening accuracy of the work rolls. [0003] When changing the roll system, the workers can only do it manually. At the same time, when changing the upper roll system, due to the deflection ang...
