Description

Technical Field

[0001] This utility model relates to a replacement device, specifically a tension roller replacement device that saves effort. Background Technology

[0002] Tension rolls are process rolls on aluminum hot rolling lines and require periodic replacement. Currently, when replacing tension rolls, it is necessary to first use a hand-operated hoist suspended inside the frame and a crane outside the frame to lift and lower the tension roll from the frame or back into the frame. This makes it difficult to avoid the risk of the hand-operated hoist or crane pulling or lifting at an angle, which could cause the roll to become unstable, get damaged, or fall off, posing a significant safety hazard. Furthermore, as tension rolls are process rolls, even a minor impact can render them unusable. Utility Model Content

[0003] The purpose of this invention is to provide a tension roller replacement device that solves the problems of safety accidents and collisions that can easily occur when replacing tension rollers.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A tension roller changing device includes a support frame, a moving trolley, and a leveling component. The support frame is provided with a track, and the moving trolley is adapted to the track. The leveling component is located at the front end of the support frame and adjusts the levelness of the support frame by changing its relative height to the support frame. The support frame is hinged with support legs via hinges.

[0006] Furthermore, the mobile trolley includes rollers, connecting rods, limiting plates, and support rods; the rollers are adapted to the track, and there are two sets of rollers, each set consisting of two rollers, with the two rollers in the same set connected by connecting rods; the limiting plates are respectively set on both sides of the connecting rods, and two limiting plates on the same side that are not in the same set are connected by support rods.

[0007] Furthermore, the support frame has two through holes symmetrically arranged at its front end, and a leveling component is arranged in each of the through holes; the leveling component includes a leveling bolt and a leveling nut, the leveling nut is located at the bottom of the support frame, and the leveling nut is adapted to the leveling bolt.

[0008] Furthermore, the hinge includes a first hinge portion and a second hinge portion, the first hinge portion is connected to the bottom of the support frame, the second hinge portion is connected to the support leg, and the first hinge portion and the second hinge portion are hinged together.

[0009] Furthermore, the support leg is T-shaped, and a locking device is provided at the bottom of the support frame to lock the support leg so that the support leg is parallel to the support frame.

[0010] Furthermore, the distance between the locking member and the hinge member is equal to the length of the supporting leg.

[0011] Furthermore, the support frame includes horizontally placed crossbeams and vertically placed legs, with the crossbeams connected end to end to form a rectangular frame; the legs are respectively distributed in the middle and rear of the rectangular frame, with figure-eight reinforcing ribs provided between the middle leg and the rear leg on the same side, and X-shaped reinforcing ribs provided between the two rear legs.

[0012] Furthermore, the rectangular frame is provided with multiple reinforcing crossbars inside.

[0013] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0014] This invention utilizes a movable trolley mounted on a support frame. With the aid of a hand-operated hoist, the tension roller is placed onto the trolley, and technicians control the trolley to push it out. This prevents the tension roller from being unstable during removal and injuring workers or causing damage to the roller itself. A leveling component is located at the front end of the support frame. After the front end of the support frame is pushed into the aluminum hot rolling mill, a leveling device is installed to ensure the support frame remains horizontal. This prevents the tension roller from falling onto the trolley, which would cause excessive stress on one side of the trolley and shorten the device's lifespan. This invention not only allows for quick and safe removal of the tension roller but also eliminates the need for immediate maintenance, improving maintenance efficiency. Attached Figure Description

[0018] Figures 1 to 3 A tension roll replacement device includes a support frame 1, a moving trolley 2, and a leveling component 3. The support frame 1 is equipped with a track 4, and the moving trolley 2 is fitted onto the track 4. The leveling component 3 is located at the front end of the support frame and adjusts the levelness of the support frame 1 by changing its relative height to the support frame 1. The support frame 1 is hinged with support legs 5 via hinges. When the tension roll needs to be replaced, the support legs 5 are first folded onto the support frame 1, making them parallel to the support frame 1 to prevent them from taking up extra space in the hot rolling mill and affecting the placement of the support frame 1. Then, technicians push the front end of the support frame 1 into the hot rolling mill and support it with the leveling component 3, making the support frame 1 horizontal for easy removal of the tension roll.

[0019] The mobile trolley 2 includes rollers 11, connecting rods 12, limiting plates 13, and support rods 14. The rollers 11 are fitted onto the track 4. There are two sets of rollers 11, each set consisting of two rollers 11. The two rollers 11 in the same set are connected by the connecting rods 12. The limiting plates 13 are respectively located on both sides of the connecting rods 12. Two limiting plates 13 on the same side that are not in the same set are connected by the support rods 14. The tension roller is removed by controlling a hand-operated hoist and then placed between the two limiting plates 13 to prevent it from rolling in the left-right direction. Then, the technician controls the mobile trolley 2 to make the rollers 11 roll on the track 4, causing the tension roller to move away from the aluminum hot rolling mill, ultimately removing the tension roller.

[0020] The support frame 1 has two symmetrical through holes at its front end, and a leveling component 3 is installed in each through hole. The leveling component 3 includes a leveling bolt 15 and a leveling nut. The leveling nut is located at the bottom of the support frame 1 and is fitted onto the leveling bolt 15. After the front end of the support frame 1 enters the hot aluminum rolling mill, the parallelism of the support frame 1 is observed. Based on the parallelism of the support frame 1, the relative height of the leveling nut on the left or right side and the leveling bolt 15 needs to be adjusted until the support frame 1 is in a horizontal state. Then, the tension roller can be placed on the support frame 1.

[0021] The hinge includes a first hinge portion and a second hinge portion. The first hinge portion is connected to the bottom of the support frame 1, and the second hinge portion is connected to the support leg 5. The first hinge portion and the second hinge portion are hinged together. The support leg 5 is T-shaped, and a locking device is provided at the bottom of the support frame 1 to lock the support leg 5, making the support leg 5 parallel to the support frame 1. The distance between the locking device and the hinge is equal to the length of the support leg 5. When the device is not in use, the support leg 5 supports the support frame 1 to prevent prolonged placement from affecting the levelness of the support frame 1. When the device needs to be pushed into the hot aluminum rolling mill, the support leg 5 is retracted under the action of the hinge and fixed to the bottom of the support frame 1 by the locking device to prevent the support leg 5 from entering the hot aluminum rolling mill and occupying space.

[0022] The support frame 1 includes horizontally placed crossbeams 21 and vertically placed legs 22, with the crossbeams 21 connected end-to-end to form a rectangular frame. The legs 22 are distributed at the middle and rear ends of the rectangular frame, with V-shaped reinforcing ribs 23 between the middle and rear legs 22 on the same side to increase the lateral strength of the support frame 1. An X-shaped reinforcing rib 24 is provided between the two rear legs 22 to increase the rear end strength of the support frame 1. Multiple reinforcing crossbars 25 are provided inside the rectangular frame to increase the top surface strength of the support frame 1.

[0023] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
