Description

Technical Field

[0001] This utility model relates to the field of aluminum foil production technology, specifically to a roller conveying trolley. Background Technology

[0002] The main function of an aluminum foil rolling mill is to roll aluminum foil blanks into aluminum foil rolls of various thicknesses and widths. Through a multi-pass rolling process, the mill can gradually thin aluminum foil blanks with a maximum thickness of 0-0.35 mm, ultimately producing aluminum foil rolls of the required thickness. The rolling mill mainly consists of the main rolling mill, transmission system, control system, and auxiliary equipment. The main rolling mill comprises rolls, roll bearings, and roll adjustment devices.

[0003] To ensure the quality of aluminum foil rolled by the aluminum foil rolling mill, the rolls need to be replaced regularly and transported to the roll placement area for maintenance. Due to the large weight of the rolls, it is inconvenient to transfer them. Existing technology usually uses a crane to move the rolls to the roll placement area. However, the rolls are prone to shaking during crane transport, which poses a high safety risk and can easily lead to the rolls falling. Summary of the Invention

[0004] To address the problem of inconvenient roll transfer in existing technologies, this utility model provides a roll transport trolley. This trolley facilitates the transfer of replaced rolls to the roll placement area, and prevents rolls from falling during the transfer process, ensuring high safety and improving the efficiency of roll transfer.

[0005] To achieve the above objectives, the technical solution of this utility model is: a roll transport trolley, including a trolley frame and movable wheels disposed at the bottom of the trolley frame. A support plate is disposed above the trolley frame, and a lifting mechanism is disposed between the support plate and the trolley frame. The lifting mechanism is used to drive the support plate to move up and down. The movable wheels facilitate the movement of the roll transport trolley by the operator, so that the roll transport trolley can transfer the replaced rolls to the roll placement area, and the lifting mechanism can drive the support plate to move up and down.

[0006] A support frame is provided on the top of the support plate, and support mechanisms are provided at both ends of the support frame. Each support mechanism includes an arc-shaped support and a movable pressure seat. The arc-shaped support is fixedly connected to the support frame, and one end of the movable pressure seat is rotatably connected to the vertical part of the support frame. A clamping assembly for pressing the movable pressure seat is movably mounted on the support frame. The arc-shaped support provides support for the roll, and the arc-shaped supports of the two support mechanisms respectively support both ends of the roll. The clamping assembly presses the movable pressure seat against the arc-shaped support, thus achieving the function of the movable pressure seat pressing the roll and preventing the roll from falling during the transfer process.

[0007] Furthermore, a handrail is fixedly installed at the top of one end of the trolley frame, and casters are installed at the bottom corners of the trolley frame. The handrail facilitates the push and pull of the roller conveyor trolley by the operator, and the casters facilitate the movement of the roller conveyor trolley.

[0008] Furthermore, the lifting mechanism includes a screw jack, a commutator, a rotating shaft, and a drive shaft. Two screw jacks are symmetrically arranged at the top of each end of the trolley frame. Each screw jack is connected to the support plate, and a commutator is provided between the two screw jacks. The screw jacks can drive the support plate to move up and down, thereby causing the support plate to drive the support mechanism to move up and down, achieving the effect of adjusting the height of the support rollers.

[0009] Furthermore, the screw jack is connected to the commutator via a rotating shaft, and the two commutators are connected via a drive shaft; one of the commutators has a handwheel shaft connected to its input end, and a handwheel is connected to one end of the handwheel shaft. Through the cooperation of the commutator, rotating shaft, and drive shaft, the screw jack can move synchronously to drive the support plate to move up and down.

[0010] Furthermore, the support frame has hinge slots and rotation slots on both sides of its end. A fixed shaft one is fixedly installed in the hinge slot, and a fixed shaft two is fixedly installed in the hinge slot. The movable pressure seat has an arc-shaped structure, and one end is fixedly connected to an ear plate, which is rotatably sleeved on the fixed shaft one. The ear plate and the fixed shaft one cooperate to facilitate the opening and closing of the movable pressure seat and the arc-shaped support, so that the roll can be placed on the arc-shaped support or the movable pressure seat can press the roll.

[0011] Furthermore, the clamping assembly includes a sleeve, a clamping screw, and a clamping screw cylinder. The sleeve is rotatably mounted on the fixed shaft. One end of the clamping screw is fixedly connected to the sleeve, and the other end is threadedly connected to the clamping screw cylinder. A pressure cap is fixedly connected to the upper end of the clamping screw cylinder. The clamping screw cylinder, through its cooperation with the clamping screw, clamps the movable pressure seat, and the pressure cap facilitates the operator's rotation of the clamping screw cylinder.

[0012] Furthermore, a groove is provided at the other end of the movable pressure seat, and a slot is provided in the groove at the position corresponding to the rotating slot. The width of the slot is smaller than the outer diameter of the clamping screw. The purpose of the groove is to enable the clamping screw to clamp the movable pressure seat, and the clamping screw can rotate into the slot so that the end of the clamping nut can abut against the groove, thereby achieving the effect of clamping the movable pressure seat with the clamping screw.

[0013] The beneficial effects of this utility model through the above technical solution are as follows:

[0014] This utility model has a reasonable structure and good performance. It facilitates the transfer of replaced rolls to the roll placement area for maintenance, replacing the method of using a crane to transport rolls. During the transfer of rolls, the rolls are less likely to shake, which can prevent the rolls from falling. It has high safety and improves the efficiency of roll transfer.

[0015] The arc-shaped support of this utility model's support mechanism supports the roll. The arc-shaped supports of the two support mechanisms can support both ends of the roll respectively, making it easy to transfer the replaced roll to the roll placement area. The clamping assembly clamps the movable pressure seat, pressing it above the arc-shaped support to achieve the purpose of the movable pressure seat pressing the roll, thus preventing the roll from falling off during the transfer process. The ear plate cooperates with the fixed shaft to facilitate the opening and closing of the movable pressure seat and the arc-shaped support, so that the roll can be placed on the arc-shaped support or the movable pressure seat can press the roll.

[0016] The screw jack of this utility model can drive the support plate to move up and down, so that the support plate drives the support mechanism to move up and down, thereby achieving the effect of adjusting the height of the support roller. In the cooperation of the commutator, the rotating shaft and the transmission shaft, the four screw jacks can move synchronously and drive the support plate to move up and down.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0024] like Figures 1-5 As shown, a roller conveying trolley includes a trolley frame 1 and movable wheels 2 disposed at the bottom of the trolley frame 1. A support plate 4 is disposed above the trolley frame 1, and a lifting mechanism is disposed between the support plate 4 and the trolley frame 1. The lifting mechanism is used to drive the support plate 4 to perform lifting and lowering movements. In this embodiment, the lifting mechanism is connected to the support plate 4 and the trolley frame 1, and the lifting mechanism can drive the support plate 4 to perform lifting and lowering movements to adjust the height of the support plate 4.

[0025] The support plate 4 is provided with a support frame 11 at the top. Both ends of the support frame 11 are provided with support mechanisms. The support mechanism includes an arc-shaped support 12 and a movable pressure seat 13. The arc-shaped support 12 is fixedly connected to the support frame 11. One end of the movable pressure seat 13 is rotatably connected to the vertical part of the support frame 11. A pressing component for pressing the movable pressure seat 13 is movably provided on the support frame 11. In this embodiment, the support mechanism supports the roll. The movable pressure seat 13 has an arc-shaped structure. Rubber pads are installed inside the arc-shaped support 12 and the movable pressure seat 13 to protect the roll and prevent damage to the contact parts between the roll and the arc-shaped support 12 and the movable pressure seat 13. The arc-shaped support 12 supports the roll. The arc-shaped supports 12 of the two support mechanisms support the two ends of the roll respectively. The movable pressure seat 13 presses the roll. The pressing assembly can press the movable pressure seat 13 above the arc-shaped support 12 to achieve the effect of pressing the roll with the movable pressure seat 13.

[0026] A handrail 3 is fixedly installed at the top of one end of the trolley frame 1, and the moving wheels 2 are installed at the bottom corners of the trolley frame 1. In this embodiment, the handrail 3 has an overall "U" shape structure. The handrail 3 is installed obliquely on the trolley frame 1, and its two ends are welded and fixed to the top of the trolley frame 1. There are four moving wheels 2 at the bottom of the trolley frame 1. The two moving wheels 2 at the front end of the trolley frame 1 are directional wheels, and the two moving wheels 2 at the rear end are omnidirectional wheels. Through the action of the handrail 3 and the moving wheels 2, it is convenient for the staff to push and pull the roller transport trolley, so as to facilitate the transfer of the replaced rollers to the roller placement area.

[0027] The lifting mechanism includes a screw jack 5, a commutator 6, a rotating shaft 7, and a drive shaft 8. Two screw jacks 5 are symmetrically arranged at the top of each end of the trolley frame 1. Each screw jack 5 is connected to the support plate 4, and a commutator 6 is provided between each screw jack 5. In this embodiment, there are four screw jacks 5 on the top of the trolley frame 1. The upper end of the screw of each screw jack 5 is connected to the support plate 4. The screw jacks 5 can drive the support plate 4 to move up and down, adjusting the height of the support plate 4, thereby achieving the effect of adjusting the height of the support mechanism. The screw jacks 5 are turbine screw jacks, specifically the KFT trapezoidal screw jack from Dezhou Demai Transmission Machinery Co., Ltd. Through the action of the commutator 6, the four screw jacks 5 can synchronously drive the support plate 4 to move up and down. The commutator 6 is a T4 commutator from Dezhou Demai Transmission Machinery Co., Ltd.

[0028] The screw jack 5 and the commutator 6 are connected by a rotating shaft 7, and the two commutators 6 are connected by a drive shaft 8. One input end of the commutator 6 is connected to a handwheel shaft 9, and one end of the handwheel shaft 9 is connected to a handwheel 10. In this embodiment, both ends of the rotating shaft 7 are connected to the worm gear of the screw jack 5 and the output end of the commutator 6, respectively. When the rotating shaft 7 drives the worm gear of the screw jack 5 to rotate, the worm gear drives the worm wheel to rotate. Because the worm wheel is connected to the screw, the worm wheel drives the screw to perform lifting and lowering motion, thereby causing the screw jack 5 to drive the support plate 4 to perform lifting and lowering motion.

[0029] The support frame 11 has a hinge groove 1201 and a rotation groove 1203 on both sides of its end. A fixed shaft 1202 is fixedly installed in the hinge groove 1201, and a fixed shaft 1204 is fixedly installed in the hinge groove 1201. The movable pressure seat 13 has an arc-shaped structure and an ear plate 1301 is fixedly connected to one end. The ear plate 1301 is rotatably sleeved on the fixed shaft 1202. In this embodiment, the hinge groove 1201 and the rotating groove 1203 provide installation positions for the first fixed shaft 1202 and the second fixed shaft 1204, respectively. The ear plate 1301 has a through hole and is fitted onto the first fixed shaft 1202 through the through hole. The cooperation between the ear plate 1301 and the first fixed shaft 1202 allows the movable pressure seat 13 to rotate, so that the movable pressure seat 13 and the arc-shaped support 12 can open and close, so that the roll can be placed on the arc-shaped support 12 or the movable pressure seat 13 can press the roll.

[0030] The clamping assembly includes a sleeve 1205, a clamping screw 1206, and a clamping cylinder 1207. The sleeve 1205 is rotatably mounted on a fixed shaft 1204. One end of the clamping screw 1206 is fixedly connected to the sleeve 1205, and the other end is threadedly connected to the clamping cylinder 1207. A pressure cap 1208 is fixedly connected to the upper end of the clamping cylinder 1207. In this embodiment, the sleeve 1205 is rotatably mounted on the fixed shaft 1204, and the clamping cylinder 1207 clamps the movable pressure seat 13. The clamping cylinder 1207 has a thread inside that matches the clamping screw 1206, allowing the clamping cylinder 1207 to rotate on the clamping screw 1206, thus facilitating the clamping cylinder 1207 to clamp the movable pressure seat 13.

[0031] The other end of the movable pressure seat 13 has a groove 1302. A slot 1303 is formed in the groove 1302 at a position corresponding to the rotation slot 1203. The width of the slot 1303 is smaller than the outer diameter of the clamping screw 1207. In this embodiment, the groove 1302 facilitates the clamping screw 1207 to clamp the movable pressure seat 13, and the slot 1303 provides space for the clamping screw 1206 to rotate, allowing the clamping screw 1206 to drive the clamping screw 1207 to rotate into the groove 1302. The purpose of the slot 1303 being smaller than the outer diameter of the clamping screw 1207 is to ensure that the clamping screw 1207 can effectively clamp the movable pressure seat 13.

[0032] The working principle of this utility model is as follows: When replacing the rolling mill rolls, the roll transport trolley is moved to the rolling mill position and the movable pressure seats 13 of the two support mechanisms are rotated. When the rolls are disassembled, the rolls are hoisted onto the trolley using a crane. The two ends of the rolls are placed on the arc-shaped supports 12 of the two support mechanisms, which support the rolls. Then, the movable pressure seats 13 of the two support mechanisms are rotated again, moving them above the arc-shaped supports 12. The movable pressure seats 13 press the rolls firmly to prevent them from falling off. Specifically... By rotating the sleeve 1205 through the pressure cap 1208, the clamping screw 1206 is rotated into the slot 1303, causing the clamping screw 1206 to drive the clamping screw cylinder 1207 to rotate into the groove 1303. Then, by rotating the clamping screw cylinder 1207 through the pressure cap 1208, the end of the clamping screw cylinder 1207 abuts against the groove 1303 to press the movable pressure seat 13. After both movable pressure seats 13 are pressed, the operator can push the roller transport trolley through the handrail 3 to transport the roller to the roller placement area. Then, the roller can be lifted off the roller transport trolley by a crane.
