Description

Technical Field

[0001] This utility model belongs to the field of spinning equipment technology, specifically relating to a lifting and installation trolley for heavy-duty bottom-mounted components. Background Technology

[0002] Large spinning assemblies need to be installed at high temperatures (200-300℃). Traditional installation methods use forklifts for lifting, but this method only allows for vertical lifting and cannot perform horizontal rotation adjustments during the lifting process. Furthermore, the high-temperature assemblies and mounting bases require precise alignment. Operators must manually push and rotate the hundreds-of-kilogram assemblies in the high-temperature environment for positioning, resulting in large positioning errors, low efficiency, and insufficient alignment accuracy with the installation station. This necessitates repeated adjustments and carries the risk of burns.

[0003] Therefore, the above problems urgently need to be solved. Utility Model Content

[0004] Purpose of the utility model: In order to overcome the above shortcomings, this utility model provides a lifting and installation trolley for heavy-duty bottom-mounted components, which shortens the replacement time of spinning components, avoids the problem of component damage caused by positioning deviation during manual operation, improves the convenience of replacing spinning components, and significantly reduces equipment maintenance costs and the labor intensity of operators.

[0005] Technical Solution: To achieve the above objectives, this utility model provides a lifting and installation trolley for heavy-duty under-mounted components, including a lifting vehicle. The lifting vehicle is equipped with a liftable fork arm, a lifting plate is fixedly connected to the liftable fork arm, a rotatable height-adjusting seat is connected to the top surface of the lifting plate, a spinning assembly is connected to the top surface of the rotatable height-adjusting seat, and a drive motor is connected to the bottom surface of the lifting plate. The motor shaft of the drive motor passes through the lifting plate and is coaxially driven and connected to the rotatable height-adjusting seat.

[0006] Furthermore, in the aforementioned lifting and mounting trolley for heavy-duty undermount components, the rotatable riser includes a flanged bearing and a support rod. The flanged bearing is connected to the top surface of the lifting plate via fasteners. The flanged portion at the lower end of the support rod is connected to the top surface of the inner ring of the flanged bearing. A tray is provided at the top of the support rod, and the spinning assembly is connected to the top surface of the tray. The motor shaft of the drive motor is coaxially connected to the lower end of the support rod via a coupling. The flanged bearing is a flanged angular contact ball bearing.

[0007] Furthermore, in the aforementioned lifting and installation trolley for heavy-duty undermount components, the tray is connected to a claw, which is connected to a groove on the outer periphery of the tray; the bottom surface of the spinning component is provided with a slot, and the slot and the claw are engaged, with the claw extending into the slot to position the tray and the spinning component.

[0008] Furthermore, in the aforementioned lifting and mounting trolley for heavy-duty undermount components, the top of the claw is provided with a guide portion, which is semi-circular or triangular.

[0009] Furthermore, in the aforementioned lifting and installation trolley for heavy-duty underloading components, the lifting vehicle is configured as a forklift, which includes a frame. One end of the frame is connected to a forklift mast, and a liftable fork arm is slidably and liftably connected to the forklift mast. A counterweight is provided on the side of the forklift mast away from the liftable fork arm. Casters are connected to the bottom of the lifting vehicle, and the casters are connected to the four sides of the bottom of the lifting vehicle. The frame is equipped with a lifting drive mechanism, which drives the liftable fork arm to rise and fall along the forklift mast.

[0010] The working steps of this utility model include:

[0011] When replacing the spinning assembly, first move the casters on the lifting vehicle to the target workstation. Use the lifting drive mechanism on the lifting vehicle to adjust the height of the adjustable fork arm, bringing the pallet close to the installation position. Then, start the drive motor. The motor shaft, through the coupling, drives the support rod and pallet to rotate. The claws in the grooves on the outer periphery of the pallet rotate synchronously with the pallet. At this time, the operator can observe the relative position of the slots on the bottom of the spinning assembly and the claws. When the claws align with the slots, fine-tune the position of the lifting vehicle to allow the semi-circular or triangular guides at the tips of the claws to smoothly slide into the slots, achieving rapid positioning of the spinning assembly and the pallet. After engagement, the drive motor drives the support rod and pallet to rotate in the direction of spinning assembly disassembly, unscrewing the spinning assembly from the textile equipment. After disassembly, lower the height of the adjustable fork arm using the lifting drive mechanism of the lifting vehicle, placing the spinning assembly stably on the ground or transfer platform. Then, reverse the operation to complete the installation of the new spinning assembly.

[0012] Throughout the operation, the flanged angular contact ball bearings can withstand the axial and radial loads of the spinning assembly, ensuring the stability of the support rod under rotation and load conditions. Meanwhile, the counterweight on one side of the frame effectively balances the overturning moment caused by the shift in the center of gravity during lifting. Combined with the flexible steering of the casters, this greatly improves the operational safety and space adaptability of the equipment in narrow workshop environments.

[0013] As can be seen from the above technical solution, this utility model has the following beneficial effects: Compared with the traditional manual installation method using hoisting tools or simple brackets, the lifting and installation trolley of this utility model for heavy-duty bottom-mounted components greatly shortens the replacement time of the spinning components, avoids the problem of component damage caused by positioning deviation during manual operation, improves the convenience of replacing the spinning components, and significantly reduces equipment maintenance costs and the labor intensity of operators.

[0021] like Figure 1-2 The illustration shows a lifting and installation trolley for heavy-duty undermount components, comprising a lifting trolley 1, a lifting fork arm 11, a lifting plate 2 fixedly connected to the lifting fork arm 11, a rotatable height-adjusting seat 3 connected to the top surface of the lifting plate 2, a spinning assembly 4 connected to the top surface of the rotatable height-adjusting seat 3, and a drive motor 5 connected to the bottom surface of the lifting plate 2. The motor shaft of the drive motor 5 passes through the lifting plate 2 and is coaxially driven by the rotatable height-adjusting seat 3. The drive motor 5 is preferably a servo motor. This invention features a rotatable height-adjusting seat 3 to facilitate the reverse positioning of the spinning assembly 4. When the spinning assembly reaches the vertical height, the drive motor 5, with its built-in encoder feedback, can monitor the rotation angle in real time and automatically stop at a preset position, accurately positioning the angle of the height-adjusting seat 3 and avoiding over-rotation or positioning deviation caused by manual judgment. In addition, the length of the support rod 32 in the rotatable height-adjustable seat 3 can be customized according to the installation height requirements of different spinning components. By replacing the support rods of different lengths, the lifting and installation trolley can be adapted to component replacement scenarios of various spinning equipment, thereby improving the versatility of the equipment.

[0022] like Figure 3The lifting and mounting trolley shown for heavy-duty undermount components includes a rotatable riser 3 comprising a flanged bearing 31 and a support rod 32. The flanged bearing 31 is connected to the top surface of the lifting plate 2 by fasteners. The flange at the lower end of the support rod 32 is connected to the top surface of the inner ring of the flanged bearing 31. A tray 321 is located at the top of the support rod 32, and the spinning assembly 4 is connected to the top surface of the tray 321. The motor shaft of the drive motor 5 is coaxially connected to the lower end of the support rod 32 via a coupling. The flanged bearing 31 is a flanged angular contact ball bearing with its contact angle facing upwards. The support rod 32 and the inner ring of the flanged bearing 31 are fastened with end face bolts to ensure the stability of torque transmission. The coupling compensates for installation errors of the motor shaft of the drive motor 5 and the support rod 32.

[0023] In this embodiment, the tray 321 is connected to a claw 3211, which is attached to a groove on the outer periphery of the tray 321. The bottom surface of the spinning assembly 4 is provided with a slot, which is engaged with the claw 3211. The claw 3211 extends into the slot to position the tray 321 and the spinning assembly 4. Three to four claws 3211 are evenly distributed on the outer periphery of the tray 321. The claws 3211 are interference-fitted with the groove of the tray 321 and fixed with fasteners, ensuring the radial stability of the claws during rotation and facilitating quick disassembly and replacement during later maintenance. The claws 3211 smoothly engage with the slot on the bottom surface of the spinning assembly 4, effectively reducing frictional resistance and noise during the engagement process.

[0024] like Figure 4-5 The lifting and mounting trolley shown is for heavy-duty undermount components. The top of the claw 3211 is provided with a guide part 32111, which is semi-circular or triangular. The guide part 32111 guides the claw 3211 into the slot at the bottom of the tray 321.

[0025] The working steps of this utility model include:

[0026] When it is necessary to replace the spinning assembly, first move the casters 15 of the lifting vehicle 1 to the target workstation. Use the lifting drive mechanism of the lifting vehicle 1 to adjust the height of the lifting fork arm 11 so that the tray 321 is initially close to the installation position. Then start the drive motor 5. The motor shaft drives the support rod 32 and the tray 321 to rotate through the coupling. The claws 3211 in the groove on the outer periphery of the tray 321 rotate synchronously with the tray. At this time, the operator can observe the relative position of the slot on the bottom of the spinning assembly 4 and the claws 3211. When the claws 3211 are aligned with the slot, fine-tune the position of the lifting vehicle so that the semi-circular or triangular guide part 32111 at the top of the claws 3211 can smoothly slide into the slot, realizing the quick positioning of the spinning assembly and the tray. After the engagement is completed, the drive motor 5 drives the support rod 32 and the tray 321 to rotate in the direction of disassembly of the spinning assembly 4, and unscrew the spinning assembly 4 from the textile equipment. After disassembly, the height of the liftable fork arm 11 is lowered by the lifting drive mechanism of the lifting vehicle 1, so that the spinning assembly 4 is placed stably on the ground or transfer platform. Then, the installation of the new spinning assembly 4 can be completed by reversing the operation.

[0027] Throughout the operation, the flanged angular contact ball bearing 31 can withstand the axial and radial loads of the spinning assembly 4, ensuring the stability of the support rod 32 under rotation and load conditions. The counterweight 14 on one side of the frame 12, with a weight ratio of at least 50% of the spinning assembly, effectively balances the overturning moment caused by the shift in the center of gravity during lifting. Combined with the flexible steering of the casters 15, it greatly improves the operational safety and space adaptability of the equipment in narrow workshop environments.

[0028] Example 2

[0029] The difference between this embodiment and Embodiment 1 is that, as Figure 6The diagram shows a lifting and installation trolley for heavy-duty underloading components. The lifting trolley 1 is an electric forklift, comprising a frame 12. One end of the frame 12 is connected to a forklift mast 13. A liftable fork arm 11 is slidably and liftably connected to the forklift mast 13. A counterweight 14 is located on the side of the forklift mast 13 away from the liftable fork arm 11. Casters 15 are connected to the bottom of the lifting trolley 1, surrounding the bottom. The frame 12 has a lifting drive mechanism that drives the liftable fork arm 11 to rise and fall along the forklift mast 13. The casters 15 are equipped with braked Foma casters. The lifting drive mechanism uses a double-acting hydraulic cylinder, controlling the lifting speed via a proportional speed control valve to achieve stepless adjustment. This satisfies the efficiency requirements for rapid lifting and also allows for smooth low-speed docking when approaching the installation position. A drive wheel is connected to the top of the cylinder shaft of the lifting drive mechanism, and a chain is connected to the liftable fork arm 11. The chain passes over the drive wheel at the top of the lifting drive mechanism and connects to the frame 12. When the lifting fork arm 11 needs to be raised, the lifting drive mechanism drives the drive wheel to rise. The drive wheel, through a chain, causes the lifting fork arm 11 to slide upward along the guide rail inside the forklift door frame 13. When lowering, the lifting drive mechanism reverses its movement and the weight of the lifting fork arm 11 achieves a smooth return. Other parts are conventionally configured and can be adjusted by those skilled in the art according to actual needs, and will not be described in detail here.

[0030] The counterweight 14 is made of cast iron and is detachably connected to the rear of the frame 12 by bolts. Its weight can be flexibly configured according to the maximum weight of the actual lifting spinning assembly 4. When the weight of the spinning assembly exceeds the bearing capacity of the basic counterweight, the anti-overturning stability of the equipment can be improved by stacking counterweights to ensure operational safety.

[0031] The above embodiments are exemplary and are intended to illustrate the technical concept and features of this utility model, so that those skilled in the art can understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
