Description

Technical Field

[0001] This utility model relates to a lifting device and a coating topcoat transfer system, belonging to the technical field of lifting devices. Background Technology

[0002] With the continuous development of the agricultural machinery manufacturing industry, the improvement of production automation level is becoming increasingly important. Promoting automated production helps reduce reliance on manual labor in the production process, and is also of great significance for eliminating operational safety hazards and stabilizing and improving the manufacturing quality of parts.

[0003] In current agricultural machinery painting production lines, the common workflow is as follows: After the electrophoresis unloading elevator descends to its position, the traveling conveyor carrying the painted parts moves along the friction line to the designated part removal and mounting area. At this point, operators need to use a scissor lift platform to ascend to a higher position to remove and mount the painted parts.

[0004] However, the operation method that relies on manual labor and mobile lifting platforms has the following problems: First, operators need to work on the lifting platform at a high altitude, which poses a risk of falling from a height; second, heavy parts pose a risk of accidental falling during manual detachment and detachment; third, the working area of ​​scissor lifts is usually narrow, which restricts the space for personnel to move around and increases the difficulty and risk of operation. Utility Model Content

[0005] The purpose of this utility model is to provide a new technical solution to improve or solve the technical problems existing in the prior art as described above.

[0006] The technical solution provided by this utility model is as follows: A lifting device includes a column, a lifting frame, a lifting drive mechanism, a telescopic frame, a telescopic drive mechanism, and a locking mechanism; the lifting frame is slidably mounted on the column, and the lifting drive mechanism is used to drive the lifting frame to move up and down along the column; the telescopic frame is slidably mounted on the lifting frame, and the telescopic drive mechanism can drive the telescopic frame to extend and retract along the Y-axis; the locking mechanism is provided on both sides of the telescopic frame, and the locking mechanism includes a locking cylinder and a locking block, the locking cylinder is fixed on the telescopic frame, and the piston rod of the locking cylinder drives the locking block to extend and retract along the X-axis.

[0007] Compared with existing technologies, the technical solution provided by this utility model has the following advantages: The lifting device of this utility model integrates lifting, telescopic, and locking functions into one unit. Vertical positioning is achieved through the lifting frame, horizontal feeding and retraction are achieved through the telescopic frame, and the locking block is driven by a locking cylinder to automatically grab and release the lifting device. The entire hook-and-loop process can be completed automatically by the lifting device, replacing manual hook-and-loop operations, thus improving operational safety and reducing the risk of falls from heights. At the same time, this lifting device simplifies operation, eliminating the need for operators to work in confined spaces at heights, reducing operational difficulty and risk, and improving work efficiency. Furthermore, the lifting device of this utility model also has advantages such as compact structure, stable operation, and accurate positioning, making it suitable for the automation needs of various coating production lines.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the lifting drive mechanism includes a lifting motor, a roller, a belt, and a counterweight; the output end of the lifting motor drives and connects to the roller; the belt is wound around the roller, one end of the belt is connected to the lifting frame, and the other end is connected to the counterweight.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the balancing system composed of belts and counterweights can offset most of the self-weight of the lifting frame and load, reduce the load power and output torque of the lifting motor, and make the lifting operation more stable and reliable.

[0011] Furthermore, it also includes a backup motor, which is connected in parallel with the lifting motor and can drive the drum.

[0012] The beneficial effect of adopting the above-mentioned further solution is that it is equipped with a dual-motor drive system (one for use and one for backup). When the main lifting motor fails, the backup motor can be activated immediately to ensure continuous normal operation, effectively avoid production interruption caused by the failure of key components, and ensure that the continuity of production and the cycle time are not affected.

[0013] Furthermore, the telescopic drive mechanism includes a telescopic motor, a ball screw, and a linear guide rail; the linear guide rail is mounted on the lifting frame; the output end of the telescopic motor is connected to the ball screw; the telescopic frame engages with the ball screw via a nut, and the telescopic frame is slidably mounted on the linear guide rail.

[0014] The beneficial effect of adopting the above-mentioned further solution is that by using a combination of ball screw pair and linear guide rail, the rotational motion of the motor is converted into linear motion, which ensures that the telescopic frame can extend and retract smoothly and accurately, thereby ensuring the alignment and locking action with the secondary lifting device.

[0015] Furthermore, the lifting frame is provided with guide wheels, which contact the surface of the column to guide the lifting movement of the lifting frame.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the guide wheel contacts the surface of the column, providing reliable lateral guidance and limiting for the up and down movement of the lifting frame, effectively preventing the lifting frame from swaying, shaking or jamming during operation, and ensuring the stability of the lifting process.

[0017] Furthermore, buffers are provided at the upper and lower limit positions of the column.

[0018] The beneficial effect of adopting the above-mentioned further solution is that by setting a buffer at the limit position of the travel, the residual kinetic energy that may exist when the lifting frame reaches the end point can be absorbed, so as to achieve flexible buffering and smooth stopping, avoid the impact, vibration and noise caused by rigid collision, protect the mechanical equipment and extend the service life of the equipment.

[0019] Furthermore, it also includes a maintenance safety device that can mechanically lock the roller when the lifting equipment is being maintained.

[0020] The advantage of adopting the above-mentioned further solution is that it prevents the roller from being accidentally started during maintenance due to misoperation or accidental power supply, thus ensuring personal safety.

[0021] This utility model also provides a coating topcoat transfer system, including a traveling conveyor, a secondary lifting device, an electrical control system, and at least one set of the aforementioned lifting equipment; the traveling conveyor is mounted on a track for carrying and transporting the secondary lifting device along the track; the lifting equipment is located on one side of the traveling path of the traveling conveyor; the telescopic frame of the lifting equipment can extend to below the secondary lifting device, and the locking mechanism of the lifting equipment is used to lock or release the secondary lifting device on the traveling conveyor after the telescopic frame extends; the electrical control system is electrically connected to the lifting drive mechanism, the telescopic drive mechanism, and the locking mechanism.

[0022] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects: The lifting equipment of this utility model adopts a combination of a lifting frame and a telescopic frame, which can accurately separate and connect the secondary lifting device (carrying painted parts) with the first V-shaped seat of the traveling conveyor. During the entire lifting process, the locking block is driven by a locking cylinder to firmly lock the secondary lifting device, eliminating the safety risk of the lifting device or painted parts falling during the transfer. The coating topcoat part transfer system of this utility model eliminates the original scissor lift platform, realizing automatic lifting and lowering of the secondary lifting device (including painted parts) and on-line operation. Employees can directly operate from the ground to perform the picking and hanging operations, eliminating safety hazards such as employees falling from heights, materials falling, and narrow working areas, while facilitating material transfer.

[0023] Based on the above technical solution, the present invention can be further improved as follows.

[0024] Furthermore, it also includes a pre-embedded foundation, on which the column of the lifting equipment is fixed.

[0025] The beneficial effect of adopting the above-mentioned further solution is that by pre-burying the foundation, the lifting equipment can be firmly fixed in the ground, providing a solid installation foundation for the equipment and eliminating the risk of overall shaking or overturning of the equipment.

[0026] Furthermore, it also includes a maintenance platform and a safety ladder, the maintenance platform being located on one side of the column, and the maintenance platform being accessible via the safety ladder.

Furthermore, the concepts of "connection" and "linkage" mentioned in this application, unless otherwise specified, are considered to include both direct connection (linkage) and indirect connection (linkage).

They are intended to facilitate explanation and simplify the description process, and are not absolute limitations on the actual location, construction method, or operating mode of the described device or element. Therefore, these terms should not be construed as restrictive interpretations of the content of this application.

[0033] The principles and features of this utility model are described below with reference to examples. The examples are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0034] like Figure 1 - Figure 10 As shown, a coating topcoat transfer system includes a traveling conveyor 7, a secondary lifting device 3, an electrical control system, and at least one lifting device. The traveling conveyor 7 is mounted on a track and is used to carry and transport the secondary lifting device 3 along the track. The lifting device is located on one side of the traveling path of the traveling conveyor 7. The telescopic frame 17 of the lifting device can extend to below the secondary lifting device 3, and the locking mechanism of the lifting device is used to lock or release the secondary lifting device 3 on the traveling conveyor 7 after the telescopic frame 17 extends. The electrical control system is electrically connected to the lifting drive mechanism, the telescopic drive mechanism, and the locking mechanism.

[0035] In this embodiment, two lifting devices are included: a first lifting device 1 and a second lifting device 2. More specifically, each lifting device includes a column 9, a lifting frame 13, a lifting drive mechanism, a telescopic frame 17, a telescopic drive mechanism, and a locking mechanism. The lifting frame 13 is slidably mounted on the column 9, and the lifting drive mechanism drives the lifting frame 13 to move up and down along the column 9. The telescopic frame 17 is slidably mounted on the lifting frame 13, and the telescopic drive mechanism drives the telescopic frame 17 to extend and retract along the Y-axis. The locking mechanism is provided on both sides of the telescopic frame 17. The locking mechanism includes a locking cylinder 14 and a locking block 15. The locking cylinder 14 is fixed on the telescopic frame 17, and the piston rod of the locking cylinder 14 drives the locking block 15 to extend and retract along the X-axis.

[0036] The lifting drive mechanism includes a lifting motor 19, a roller 20, a belt 21, and a counterweight 10. The output end of the lifting motor 19 drives and connects to the roller 20. The belt 21 is wound around the roller 20, with one end connected to the lifting frame 13 and the other end connected to the counterweight 10. The balancing system composed of the belt 21 and the counterweight 10 can offset most of the weight of the lifting frame 13 and the load, reducing the load power and output torque of the lifting motor 19, while making the lifting operation smoother and more reliable.

[0037] The lifting device also includes a backup motor 23, which is connected in parallel with the lifting motor 19 and can drive the drum 20. Equipped with a dual-motor drive system (one in use and one on standby), when the main lifting motor 19 fails, the backup motor 23 can be immediately activated to ensure continuous normal operation, effectively avoiding production interruptions caused by critical component failures and ensuring that production continuity and cycle time are not affected.

[0038] The telescopic drive mechanism includes a telescopic motor 27, a ball screw 26, and a linear guide rail 16. The linear guide rail 16 is mounted on the lifting frame 13. The output end of the telescopic motor 27 drives and connects to the ball screw 26. The telescopic frame 17 engages with the ball screw 26 via a nut and slides on the linear guide rail 16. The combination of the ball screw 26 and the linear guide rail 16 converts the rotational motion of the motor into linear motion, ensuring that the telescopic frame 17 can extend and retract smoothly and accurately, thereby ensuring alignment and locking with the secondary lifting device 3.

[0039] The lifting frame 13 is equipped with guide wheels 18, which contact the surface of the column 9 to guide the lifting movement of the lifting frame 13. The contact between the guide wheels 18 and the surface of the column 9 provides reliable lateral guidance and limiting for the up-and-down movement of the lifting frame 13, effectively preventing the lifting frame 13 from swaying, shaking, or jamming during operation, and ensuring the stability of the lifting process.

[0040] Buffers 11 are installed at both the upper and lower limit positions of the column 9. The buffers 11 at the limit positions can absorb the residual kinetic energy that may exist when the lifting frame 13 reaches the end point, so as to achieve flexible buffering and smooth stopping, avoid the impact, vibration and noise caused by rigid collision, protect the mechanical equipment and extend the service life of the equipment.

[0041] The lifting equipment also includes a maintenance safety device 22, which can mechanically lock the roller 20 when the lifting equipment is being maintained, preventing the roller 20 from being accidentally started due to misoperation or accidental power supply during maintenance, thus ensuring personal safety.

[0042] The coating topcoat transfer system also includes a pre-embedded foundation 28, a maintenance platform 24, and a safety ladder 25. The column 9 of the lifting equipment is fixed to the pre-embedded foundation 28. The pre-embedded foundation 28 securely fixes the lifting equipment to the foundation 5, providing a solid installation base and eliminating the risk of overall equipment swaying or tipping. The maintenance platform 24 is located on one side of the column 9 and is accessible via the safety ladder 25. The dedicated maintenance platform 24 and safety ladder 25 provide a safe operating space for daily equipment inspection, maintenance, and troubleshooting, improving equipment maintainability and the safety of maintenance operations.

[0043] In this embodiment, the traveling conveyor 7 is provided with a first V-shaped seat 29, the secondary hoist 3 is provided with a second V-shaped seat 30, and the locking block 15 also adopts a V-shaped structure design.

[0044] The working process of the coating topcoat transfer system of this utility model mainly includes topcoat unloading (removal) and topcoat loading (hanging). The topcoat unloading process is to remove the painted part 4 from the conveyor line, and the topcoat loading process is to hang the painted part 4 on the conveyor line. The working process includes the following steps: The topcoat removal process includes: S1. The traveling conveyor 7, carrying the painted parts 4 and the secondary lifting device 3, runs along the track to the part removal and hanging operation area directly in front of the lifting equipment through its friction drive wheel set 8 and stops.

[0045] S2. Start the lifting motor 19 of the lifting drive mechanism. The lifting motor 19 drives the roller 20 to rotate. Through the coordinated action of the belt 21 and the counterweight 10, the lifting frame 13 is driven to descend smoothly along the column 9 until it reaches the preset docking height. During this process, the guide wheel 18 ensures that the lifting frame 13 does not wobble.

[0046] S3. After the lifting frame 13 is in position, the telescopic drive mechanism is activated. The telescopic motor 27 drives the ball screw 26 to rotate, pushing the telescopic frame 17 to extend horizontally along the linear guide rail 16 in the Y-axis direction (i.e. towards the traveling conveyor 7) until it moves directly below the secondary lifting device 3.

[0047] S4. After the telescopic frame 17 is in place, the piston rod of the locking cylinder 14 is pushed out, driving the locking block 15 to move along the X-axis and lock into the second V-shaped seat 30 of the secondary lifting device 3.

[0048] S5. The lifting drive mechanism starts again, and the lifting frame 13 lifts the secondary lifting device 3 and the painting part 4 upward as a whole, so that they are separated from the first V-shaped seat 29 of the walking conveyor 7.

[0049] Then, the telescopic motor 27 reverses, driving the telescopic frame 17 to retract, moving the secondary lifting device 3 and the painted parts 4 200-300mm away from the conveyor belt 7, thus leaving the conveyor belt area.

[0050] Finally, the lifting frame 13 descends, lowering the secondary lifting device 3 and the painted parts 4 to the operating height of the ground staff. At this time, the operators can safely stand on the surface of the foundation 5 and directly carry out the removal operation of the painted parts 4.

[0051] The topcoat application process includes: S6. The operator hangs the parts to be painted 4 on the unloaded secondary lifting device 3. S7. The lifting drive mechanism is started, raising the secondary lifting device 3, which carries the part to be painted 4, to the specified height; S8. Subsequently, the telescopic drive mechanism is activated, driving the telescopic frame 17 to extend again, sending the second V-shaped seat 30 above the first V-shaped seat 29.

[0052] S9. The piston rod of the locking cylinder 14 retracts, causing the locking block 15 to exit from below the second V-shaped seat 30, releasing the lock and separating the secondary lifting device 3 from the lifting equipment. The telescopic frame 17 retracts, returning to its initial position within the lifting frame 13, which then rises to the standby height.

[0053] S10. After the entire lifting equipment has been reset, the traveling conveyor 7, carrying the secondary hoist 3 with the new painted parts 4 attached, drives away to enter the next painting cycle.

[0054] This invention replaces the traditional and dangerous manual high-altitude operation mode with a fully automated sequence of lifting, extending, locking, transferring, and lowering actions, achieving safe and efficient automated transfer operations.

[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
