Description

Technical Field

[0001] The present application relates to the technical field of roller maintenance, and in particular to a bracket for roller maintenance. Background Art

[0002] The main working parts and tools on the rolling mill that cause continuous plastic deformation of metal. The roller is mainly composed of three parts: the roller body, the roller neck and the shaft head. The roller body is the middle part of the roller that actually participates in rolling the metal. It has a smooth cylindrical or grooved surface. The roller neck is installed in the bearing and transmits the rolling force to the frame through the bearing seat and the pressing device. The transmission end shaft head is connected to the gear seat through the connecting shaft to transmit the rotational torque of the motor to the roller.

[0003] After the rollers have been used for a period of time, they need to be disassembled for regular repair and maintenance. Currently, rollers are usually placed directly on the ground or on a bracket during repair. Since rollers are usually heavy and large in size, placing them directly on the ground makes them inconvenient to rotate and may pose a safety hazard. When placed on a bracket, the rollers cannot rotate and some parts are not easy to expose, which affects repair or maintenance.

[0004] Our company has previously applied for a Chinese patent with announcement number CN219766383U, which discloses a roller rotating bracket, including a base, a rotating mechanism installed on the base and a pressing assembly. A group of rollers are driven to rotate by rotating the turntable, and then the rollers drive the rollers to rotate through their friction. The end position of the roller can also be changed by rotating the support plate 180 degrees on the turntable, and the limit part passes through the hole at the end of the support plate and is inserted into the base to limit the rotation again, so that the staff can adjust the position of the roller for inspection, repair and maintenance.

[0005] Although it solves the problem that the existing rolling rollers are difficult to repair and maintain, in actual use, due to the frequent use of locking bolts, positioning bolts and other parts, adjustment and fixation are more troublesome. At the same time, the position of the pressing assembly has to be moved every time the material is loaded and unloaded, otherwise it will affect the loading and unloading. The whole process is more cumbersome and time-consuming.

[0006] Therefore, it is urgent to make further improvements on this basis. Utility Model Content

[0007] The purpose of the present application is to provide a roller maintenance bracket that is easy to load and unload and convenient for workers to repair, so as to solve the problems raised in the above-mentioned background technology.

[0008] To achieve the above purpose, the present application provides a roller maintenance bracket adopting the following technical solution:

[0009] A roller maintenance bracket comprises a base, a support mechanism mounted on the base, the support mechanism comprises a reduction motor fixed on the base, a power support seat and a driven support seat, the power support seat is connected to two active roller shafts rotatably side by side, the active roller shafts are driven by the reduction motor, the driven support seat is connected to two driven roller shafts rotatably side by side, and the driven roller shaft is coaxially arranged with the active roller shaft;

[0010] The power support seat and the driven support seat are both connected with a pressure roller mechanism, and the pressure roller mechanism includes a rotating frame, a clamping cylinder, a clamping roller and a driving cylinder. The two rotating frames are respectively hinged on the power support seat and the driven support seat, the clamping cylinder is fixed on the rotating frame, a mounting frame is fixed on the end of the output shaft of the clamping cylinder, the clamping roller is rotatably connected in the mounting frame, one end of the driving cylinder is hinged on the rotating frame, and the other end is hinged on the base, and the driving cylinder is used to open the rotating frame toward the outside of the base.

[0011] A first gear is fixed to one end of the two active roller shafts close to the reduction motor, a second gear is meshed between the two first gears, the second gear is rotatably connected to the power support seat, and a third tooth meshing with the first gear is fixed to the output shaft of the reduction motor.

[0012] Preferably, in order to increase friction and ensure reliable transmission, the surfaces of the active roller, the driven roller and the pressure roller are all wrapped with a rubber layer.

[0013] Preferably, a baffle is fixed to one side of the driven support seat, and the height of the upper surface of the baffle is lower than the height of the upper surface of the driven roller.

[0014] By adopting the above technical solution, the setting of the baffle can limit the position of the roller, thereby making it convenient for the staff to place the roller.

[0015] The bottom corner of the rotating frame close to the driving cylinder is chamfered.

[0016] To summarize, the present application includes at least one of the following beneficial technical effects: the roller maintenance bracket drives the roller to rotate through the reduction motor, which can reduce the labor intensity of the staff. At the same time, the rotating frame in the pressure roller mechanism is hinged on the power support seat and the driven support seat. During the loading and unloading process, it can be flipped to both sides by driving the cylinder, leaving loading and unloading space for the roller, making loading and unloading relatively convenient, thereby improving the efficiency of maintenance.

[0021] The present application embodiment discloses a roller maintenance bracket, referring to Figure 1-2 , comprising a base 1, a supporting mechanism mounted on the base 1, the supporting mechanism comprising a reduction motor 2 fixed on the base 1, a power support seat 3 and a driven support seat 4, the power support seat 3 is connected to two active roller shafts 31 rotatably side by side, the active roller shaft 31 is driven by the reduction motor 2, and the driven support seat 4 is connected to two driven roller shafts 41 rotatably side by side, and the driven roller shaft 41 is coaxially arranged with the active roller shaft 31;

[0022] A pressure roller mechanism 5 is connected to both the power support seat 3 and the driven support seat 4. The pressure roller mechanism 5 includes a rotating frame 51, a clamping cylinder 52, a clamping roller 53 and a driving cylinder 54. The two rotating frames 51 are respectively hinged on the power support seat 3 and the driven support seat 4. The clamping cylinder 52 is fixed on the rotating frame 51. A mounting frame is fixed to the end of the output shaft of the clamping cylinder 52. The clamping roller 53 is rotatably connected in the mounting frame. One end of the driving cylinder 54 is hinged on the rotating frame 51, and the other end is hinged on the base 1. The driving cylinder 54 is used to open the rotating frame 51 toward the outside of the base 1. The bottom corner of the rotating frame 51 close to the driving cylinder 54 is chamfered.

[0023] In order to ensure reliable friction transmission, the surfaces of the active roller shaft 31 , the driven roller shaft 41 and the pressing roller 53 are all wrapped with a rubber layer.

[0024] Reference Figure 1 In order to make the transmission more reliable, the two active roller shafts 31 are respectively fixed with a first gear 311 at one end close to the reduction motor 2, and a second gear 32 is meshed between the two first gears 311. The second gear 32 is rotatably connected to the power support seat 3, and a third gear 21 meshing with the first gear 311 is fixed on the output shaft of the reduction motor 2.

[0025] Reference Figure 2In order to facilitate the staff to place the rolling rollers, a baffle 6 is fixed to one side of the driven support seat 4, which can play a role of limiting.

[0026] The implementation principle of a roller maintenance bracket in the embodiment of the present application is:

[0027] During maintenance, the staff only needs to hoist the roll above the bracket, and then place it on the power support seat 3 and the driven support seat 4 on both sides, and the driving cylinder 54 extends to push the rotating frame 51 to flip to a vertical state, and the pressing cylinder 52 on the rotating frame 51 extends to push the pressing roller 53 to press on the roll, so that the roll can be positioned on the bracket;

[0028] Thereafter, the reduction motor 2 works to drive the first gear 311 to rotate via the third gear 21, and the first gear 311 drives the active roller shaft 31 to rotate, thereby driving the roller to rotate for the convenience of inspection by the staff. When repairing, the reduction motor 2 can be stopped.
