Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a lifting seat and a lifting machine. Background Technology

[0002] In suspended logistics systems, vertical lifts are frequently used to raise vehicles from low to high places, and even for long distances across floors. For an explanation of the working principle of vertical lifts, please refer to the patent document with application number 201911070648.5, which describes a rotary coat hanger-shaped lifting device.

[0003] In existing vertical lifting machines, the lifting components of the lifting vehicle have relatively simple structures, resulting in insufficient stability during movement. Summary of the Invention

[0004] This utility model addresses the aforementioned problems in the existing technology by providing a lifting seat for a hoist. The technical problem to be solved by this utility model is: how to improve stability during movement.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A lifting seat for a hoist, the hoist including a frame, the frame including a vertically extending main rail, two opposing guide rails mounted on the main rail, the lifting seat including a seat body, characterized in that the seat body is provided with two or more rollers, at least one of the rollers being rotatably connected to the inner side of one guide rail, and at least one of the rollers being rotatably connected to the inner side of another guide rail.

[0007] The lifting seat is driven by a drive source consisting of a motor and a chain. The lifting seat body is equipped with rollers, at least two rollers. At least one roller is tumblingly connected to the inside of one guide rail, and at least one roller is tumblingly connected to the inside of another guide rail. The two guide rails together provide guidance. The seat body is tumblingly connected to the guide rails on the main track through the rollers, resulting in smooth movement and good stability.

[0008] In the lifting seat of the aforementioned hoist, the seat body is provided with two or more rollers, which are located on one side and the other side of the seat body and are tumblingly connected to the main track.

[0009] There are at least two rollers. At least one roller is located on one side of the seat and is rolled on the main track. At least one roller is located on the other side of the seat and is rolled on the main track. The seat is also rolled on the main track through rollers. Rollers 2 and 1 are distributed at different positions on the seat and are rolled on different parts of the main track respectively. The combination of the two further improves the stability of the lifting seat when it moves.

[0010] In the lifting seat of the aforementioned hoist, the frame includes a base, on which the main track is provided, and at the bottom and top of the main track are respectively provided a driving wheel and a driven wheel, with a chain connected to the driving wheel and the driven wheel. A motor is mounted on the base, the driving wheel is mounted on the output shaft of the motor, and the seat is mounted on the chain.

[0011] The motor drives the drive wheel to rotate, and the drive wheel drives the driven wheel to rotate through the chain. At the same time, the chain moves up and down, which in turn drives the lifting seat to move up and down.

[0012] In the lifting seat of the aforementioned hoist, the main track is provided with a receiving groove and two positioning grooves. The positioning grooves are connected to the receiving groove and are located on one side and the other side of the receiving groove. The chain is located in the receiving groove, and a connecting shaft is provided on the chain. One end and the other end of the connecting shaft are slidably connected to the corresponding positioning grooves, respectively. The rollers are rotatably connected to the main track on one side and the other side of the receiving groove.

[0013] In this structure, one end of the connecting shaft and the other end are slidably connected in corresponding positioning grooves. The two positioning grooves guide and limit the connecting shaft, making it less prone to shaking when the chain moves, thus improving stability and further enhancing the stability of movement.

[0014] In the lifting seat of the aforementioned hoist, a chamfer is provided at the edge of the groove opening of the positioning groove.

[0015] A chamfer is provided on the edge of the slot, which makes it easier for the end of the connecting shaft to be inserted into the positioning slot, thus improving the ease of installation.

[0016] In the lifting seat of the aforementioned hoist, two mounting plates are provided on the top of the main track. Each mounting plate is provided with a clearance groove, a limiting block, and two guide rails. The guide rails are slidably connected to the mounting blocks, and a mounting shaft is connected between the mounting blocks. The mounting shaft passes through the two clearance grooves, and the driven wheel is rotatably connected to the mounting shaft. A tensioning rod is provided on the mounting block. The tensioning rod extends from the top of the limiting block, and a spring and a nut are sleeved on the tensioning rod. One end of the spring and the other end abut against the limiting block and the nut, respectively.

[0017] The tensioning structure consists of a tensioning rod, a spring, a limiting block, and a nut. When the nut is rotated, the spring is compressed. Under the action of the spring's elastic force, the tensioning rod drives the mounting block to move upward, thereby causing the driven wheel to move upward and increasing the distance between the driven wheel and the driving wheel, thus tensioning the chain and keeping it taut.

[0018] There are two tensioning structures, which are used simultaneously during adjustment. The second guide rail serves as a guide and limiter, ensuring that the driven wheel can only move up and down. The relative position of the driven wheel and the driving wheel changes only in the height direction, while the relative position of the driven wheel and the driving wheel remains unchanged in other directions.

[0019] In the lifting seat of the aforementioned lifting machine, the roller is located at the inner end of the seat body, and a trigger block and a lifting plate are provided at the outer end of the seat body. The top of the lifting plate is inclined, and the trigger block is located above the lifting plate. One side of the trigger block has an inclined surface that gradually extends outward from top to bottom. A rotating wheel is also provided on the seat body, and the rotating wheel includes several levers extending in all directions.

[0020] When entering the rack, the trigger block is used to swing the swing block on the entrance subrail, thereby moving the vehicle to the lifting plate and automatically attaching the vehicle to the rack. Then the vehicle slides down along the lifting plate. When exiting the rack, some levers are used to abut against the disengagement subrail and rotate the wheel, while other levers drive the vehicle to move onto the disengagement subrail, so that the vehicle automatically exits the rack.

[0021] This utility model also provides a hoist, which includes any of the above-mentioned hoisting seats.

[0022] Compared with the prior art, the advantages of this utility model are as follows:

[0023] 1. The base of the lifting seat is connected to the guide rail on the main track by roller 1, which allows for smooth movement and good stability.

[0024] 2. Rollers 2 and 1 of the lifting seat are distributed at different positions on the seat body and are respectively connected to different parts of the main track. The combination of the two further improves the stability of the lifting seat when it moves. Attached Figure Description

[0031] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0032] like Figure 1 , 2 As shown in Figure 5, the hoist includes a frame 1, the frame 1 includes a vertically extending main rail 2, and two opposing guide rails 3 are installed on the main rail 2. The hoisting seat includes a seat body 4, and the seat body 4 is provided with two or more rollers 5. At least one roller 5 is rotatably connected to the inner side of one guide rail 3, and at least one roller 5 is rotatably connected to the inner side of another guide rail 3.

[0033] The lifting seat is driven by a drive source consisting of a motor 11 and a chain 10. The seat body 4 of the lifting seat is equipped with rollers 5. There are at least two rollers 5; in one embodiment, four rollers 5 are used. Two rollers 5 are located on one side of the seat body 4 and are rotatably connected to the inside of a guide rail 3. The other two rollers 5 are located on the other side of the seat body 4 and are rotatably connected to the inside of another guide rail 3. The two guide rails 3 serve a guiding function. The seat body 4 is rotatably connected to the guide rails 3 on the main track 2 via the rollers 5, ensuring smooth and stable movement of the lifting seat. The two guide rails 3 also serve a limiting function, ensuring that the lifting seat does not deviate during vertical movement.

[0034] In other embodiments, the number of rollers 5 can also be odd, such as three rollers 5, one of which is located on one side of the base 4 and is rotatably connected to the inside of a guide rail 3, and the other two rollers 5 are located on the other side of the base 4 and are rotatably connected to the inside of another guide rail 3.

[0035] For example, there are five rollers 5, two of which are located on one side of the base 4 and are rotatably connected to the inside of a guide rail 3. The other three rollers 5 are located on the other side of the base 4 and are rotatably connected to the inside of another guide rail 3.

[0036] like Figure 1As shown, in this embodiment, the seat 4 is provided with two or more rollers 6, which are located on one side and the other side of the seat 4 and are tumblingly connected to the main track 2.

[0037] There are at least two rollers 6. At least one roller 6 is located on one side of the seat body 4 and is tumblingly connected to the main track 2. At least one roller 6 is located on the other side of the seat body 4 and is tumblingly connected to the main track 2. The seat body 4 is tumblingly connected to the main track 2 through rollers 6. Rollers 6 and roller 5 are distributed at different positions on the seat body 4 and are tumblingly connected to the main track 2 and guide rail 3 respectively. The combination of the two further improves the stability of the lifting seat when it moves.

[0038] like Figure 2-4 As shown, in this embodiment, the frame 1 includes a base 7, a main track 2 is provided on the base 7, a drive wheel 8 and a driven wheel 9 are respectively provided at the bottom and top of the main track 2, a chain 10 (not shown) is connected to the drive wheel 8 and the driven wheel 9, a motor 11 is installed on the base 7, the drive wheel 8 is installed on the output shaft of the motor 11, and the seat 4 is installed on the chain 10.

[0039] Motor 11 drives drive wheel 8 to rotate, drive wheel 8 drives driven wheel 9 to rotate via chain 10, chain 10 moves up and down at the same time and drives the lifting seat to move up and down.

[0040] like Figure 1 and 5 As shown, in this embodiment, the main track 2 is provided with a receiving groove 12 and two positioning grooves 13. The positioning grooves 13 are connected to the receiving groove 12 and are located on one side and the other side of the receiving groove 12. The chain 10 (not shown) is located in the receiving groove 12. The chain 10 is provided with a connecting shaft 14. One end and the other end of the connecting shaft 14 are slidably connected in the corresponding positioning grooves 13. The roller 6 is rotatably connected to the main track 2 on one side and the other side of the receiving groove 12.

[0041] In this structure, one end of the connecting shaft 14 and the other end are slidably connected in the corresponding positioning grooves 13. The two positioning grooves 13 guide and limit the connecting shaft 14, making it less prone to shaking when the chain 10 moves, thus improving stability and further enhancing the stability of movement.

[0042] Preferably, the edge of the groove opening of the positioning groove 13 is chamfered.

[0043] The positioning groove 13 has a chamfered edge, which makes it easier for the end of the connecting shaft 14 to be inserted into the positioning groove 13, thus improving the ease of installation.

[0044] like Figure 3As shown, in this embodiment, the top of the main track 2 is provided with two mounting plates 15. Each mounting plate 15 is provided with a clearance groove 16, a limiting block 17 and two guide rails 18. The guide rails 18 are slidably connected to each other, and the mounting blocks 19 are connected to each other with a mounting shaft 20. The mounting shaft 20 passes through the two clearance grooves 16. The driven wheel 9 is rotatably connected to the mounting shaft 20. The mounting block 19 is provided with a tension rod 21. The tension rod 21 passes through the top of the limiting block 17. A spring 22 and a nut 23 are sleeved on the tension rod 21. One end of the spring 22 and the other end abut against the limiting block 17 and the nut 23, respectively.

[0045] The tensioning structure consists of tensioning rod 21, spring 22, limiting block 17, and nut 23. Nut 23 is threadedly connected to tensioning rod 21. When nut 23 is rotated, spring 22 is compressed. Under the elastic force of spring 22, tensioning rod 21 drives mounting block 19 to move upward. At the same time, mounting shaft 20 moves in the two relief grooves 16, thereby causing driven wheel 9 to move upward, increasing the distance between driven wheel 9 and driving wheel 8, thus tensioning chain 10 and keeping chain 10 taut.

[0046] There are two tensioning structures, which are used simultaneously during adjustment. The second guide rail 18 serves as a guide and limiter, so that the driven wheel 9 can only move up and down. The relative position of the driven wheel 9 and the driving wheel 8 changes only in the height direction, while the relative position of the driven wheel 9 and the driving wheel 8 remains unchanged in other directions.

[0047] like Figure 1 As shown, in this embodiment, roller 5 is located at the inner end of the base 4, and a trigger block 24 and a lifting plate 25 are provided at the outer end of the base 4. The top of the lifting plate 25 is inclined, and the trigger block 24 is located above the lifting plate 25. One side of the trigger block 24 has an inclined surface 26, which gradually extends outward from top to bottom. A rotating wheel 27 is also provided on the base 4, and the rotating wheel 27 includes several levers 28 extending in all directions.

[0048] When entering the rack, the trigger block 24 is used to swing the swing block on the entrance subrail, thereby moving the vehicle onto the lifting plate 25, so that the vehicle is automatically attached to the rack. Then the vehicle slides down along the lifting plate 25. When exiting the rack, some levers 28 are used to abut against the disengagement subrail and make the rotating wheel 27 rotate, while other levers 28 drive the vehicle to move onto the disengagement subrail, so that the vehicle is automatically exited from the rack.

[0049] This utility model also provides a hoist, which includes any of the above-mentioned hoisting seats.
