Description

Technical Field

[0001] This utility model belongs to the field of passenger vehicle manufacturing technology, and in particular relates to a transfer trolley for passenger vehicle painting production. Background Technology

[0002] Bus painting is an important part of the bus manufacturing process. Buses travel outdoors and face various harsh weather conditions and complex road conditions. Painting can prevent the metal parts of the bus body from rusting and corroding, and extend the service life of the bus. By selecting paints with different colors, gloss and textures, the appearance of the bus can be made more beautiful and attractive, enhancing the overall image and market competitiveness of the bus, and meeting customers' needs for personalization and aesthetics.

[0003] For example, Chinese patent CN221316468U discloses a transfer trolley for bus painting production, including a frame with an adjustment mechanism on the upper surface of the frame. This transfer trolley for bus painting production, through the arrangement of an electrical box, support plate, connecting frame, adjusting rod, rear seat, fixing block, first bolt, cylinder, slide rod, lifting plate, second bolt, first circular groove, second circular groove, and slide groove, allows for adjustments when the vehicle length exceeds the trailer length. First, the second bolt is unscrewed and removed from the first and second circular grooves. Then, the rear seat is dragged to adjust the trailer length appropriately. Next, the first and second circular grooves are aligned, and the second bolt is passed through the adjusting rod and tightened. This completes the trailer length adjustment. When the vehicle base limit needs adjustment, the electrical box is opened to start the cylinder, which drives the lifting plate to move. Simultaneously, the slide rod slides inside the slide groove, completing the limit height adjustment.

[0004] The aforementioned patent has the following problems:

[0005] This patent has some drawbacks in its use, such as the need to remove the second bolt before adjusting the length of the adjusting rod, which is cumbersome. Furthermore, the device requires a trailer for movement, which is inconvenient for short-distance transport or in small transport areas. Therefore, we propose a transport trolley for bus painting production. Utility Model Content

[0006] The purpose of this utility model is to provide a transfer trolley for passenger vehicle painting production, so as to solve the problems mentioned in the background art.

[0007] In view of this, the present invention provides a transfer trolley for passenger vehicle painting production, comprising:

[0008] A fixed frame is provided, with symmetrical sliding grooves inside the fixed frame. Sliding rods are slidably installed in both sliding grooves. One end of each sliding rod passes through one side of the two sliding grooves and is fixedly installed with the same movable frame. A rotating shaft is rotatably installed at the bottom of the movable frame, and a power wheel is fixedly installed at both ends of the rotating shaft.

[0009] A drive assembly, which is located within one of the sliding grooves and is used to drive one of the sliding rods to move;

[0010] A power assembly, located on a movable frame, is used to drive the rotating shaft to rotate;

[0011] Two rotating frames are symmetrically mounted on the bottom of a fixed frame. A directional wheel is rotatably mounted inside each rotating frame. A hydraulic cylinder is fixedly mounted on the fixed frame. A compression plate is fixedly mounted on the output end of the hydraulic cylinder. A rubber block is fixedly mounted on the top of the compression plate. A hydraulic cylinder is symmetrically mounted on a movable frame. A compression plate is fixedly mounted on the output end of the hydraulic cylinder. A rubber block is fixedly mounted on the top of the compression plate.

[0012] In this technical solution, during use, personnel can first move one of the sliding rods according to the length of the bus using the set drive components. The movement of one sliding rod will drive the moving frame to move, and the movement of the moving frame will drive the other sliding rod to slide. At the same time, the movement of the moving frame will also drive the two power wheels to rotate until the moving frame is moved to the appropriate position and then stop. At this time, personnel can push the entire device into the bottom of the bus. Then, hydraulic cylinder one and two hydraulic cylinders two are activated. The output shaft of hydraulic cylinder one will drive the extrusion plate one to move upward. The extrusion plate one will move upward and press against the bottom of the bus through rubber block one. At the same time, the output shafts of the two hydraulic cylinders two will drive the two extrusion plates two to move upward respectively. The two extrusion plates two will press against the bottom of the bus through two rubber blocks two respectively. Under the extrusion of the two rubber blocks two and rubber block one, the bus can be lifted up, ensuring that buses of different lengths can be lifted up. Moreover, no other tools are needed in the process of adjusting the extension length of the moving frame, which is convenient and quick.

[0013] The power unit then drives the rotating shaft to rotate, which in turn drives two power wheels to rotate. The rotation of the two power wheels then moves the entire device, making it easier for personnel to move the bus. When a turn is needed, the fixed frame can be rotated, at which point the two rotating frames will rotate at the bottom of the fixed frame. The rotation of the rotating frames will drive the steering wheels to rotate, thereby turning the vehicle. This ensures that the entire device does not require the use of other trailers for movement, making it convenient for short-distance bus transfers.

[0014] In the above technical solution, the driving component further includes:

[0015] A threaded rod is rotatably mounted in one of the sliding grooves. One end of the threaded rod extends into one of the sliding grooves, and the other end of the threaded rod extends through the other side of one of the sliding grooves to the outside and is fixedly mounted with a handle.

[0016] In this technical solution, turning the handle causes the threaded rod to rotate. Under the action of the thread, the rotation of the threaded rod causes one of the sliding rods to move. The movement of the sliding rod causes the moving frame to move. The movement of the moving frame causes the other sliding rod to slide. At the same time, the movement of the moving frame also causes the two drive wheels to rotate until the moving frame is moved to the appropriate position and stops. This ensures that buses of different lengths can be lifted. Moreover, no other tools are needed to adjust the extension length of the moving frame, which is convenient and quick.

[0017] In the above technical solution, the threaded rod is further threadedly connected to the corresponding sliding rod, and the other end of the threaded rod is rotatably connected to the fixed frame.

[0018] In this technical solution, the rotation of the threaded rod is ensured to drive one of the sliding rods to move, and the other end of the threaded rod can rotate normally within the fixed frame.

[0019] In the above technical solution, the power component further includes:

[0020] A second bevel gear is fixedly mounted on a rotating shaft and located between two power wheels. A first bevel gear is meshed with the top of the second bevel gear. A mounting box is fixedly mounted on the moving frame and located between two second hydraulic cylinders. A motor is fixedly mounted inside the mounting box. The output end of the motor passes through the bottom of the mounting box and is coaxially connected to the bevel gear.

[0021] In this technical solution, starting the motor causes the output shaft to drive a first bevel gear to rotate. Under meshing action, the rotation of the first bevel gear drives the rotation of a second bevel gear, which in turn drives the rotating shaft to rotate. The rotation of the rotating shaft then drives two power wheels to rotate, which in turn moves the entire device. This makes it easier for personnel to move the bus. When turning, personnel can hold onto the handrail and rotate the fixed frame. At this time, the two rotating frames will rotate at the bottom of the fixed frame. The rotation of the rotating frames will drive the steering wheels to rotate, thereby turning the vehicle. This ensures that the entire device does not require the use of other trailers for movement, making it convenient for short-distance bus transport.

[0022] In the above technical solution, the output shaft of the motor is rotatably connected to the mounting box.

[0023] In this technical solution, it is ensured that the output shaft of the motor can rotate normally within the mounting box.

[0024] Furthermore, the above technical solution also includes:

[0025] The handrail is fixedly installed on the top of the fixed frame and on one side of the hydraulic cylinder. A storage battery is fixedly installed inside the fixed frame and between two sliding grooves. The storage battery is electrically connected to the motor, the hydraulic cylinder, and the two hydraulic cylinders.

[0026] In this technical solution, it is ensured that the handrail is easy for people to hold, that the battery can supply power to the motor, hydraulic cylinder one, and the two hydraulic cylinders two, and that the motor, hydraulic cylinder one, and the two hydraulic cylinders two can operate normally.

[0027] In the above technical solution, the bottom of the power wheel and the bottom of the steering wheel are located on the same horizontal plane, and the cross-section of the sliding rod is T-shaped.

[0028] In this technical solution, the overall device can operate more smoothly, ensuring that the sliding rod will not fall out of the sliding groove.

[0029] The beneficial effects of this utility model are:

[0030] 1. This transfer trolley for bus painting production, through the coordinated operation of the drive assembly, two sliding rods, a moving frame, two power wheels, hydraulic cylinder one, two hydraulic cylinder two, extrusion plate one, rubber block one, two extrusion plates two, and two rubber blocks two, ensures that buses of different lengths can be lifted. Furthermore, no other tools are needed to adjust the extension length of the moving frame, making it convenient and quick.

[0031] 2. The bus painting production transfer trolley, through the setting of the power unit, the rotating shaft, two power wheels, two rotating frames and two directional wheels, ensures that the whole device does not need to be moved by other trailers when in use, thus facilitating short-distance transfer of buses, which is quite convenient.

[0045] Example 1:

[0046] Please see Figure 1 - Figure 6 As shown, this embodiment provides a transfer trolley for passenger vehicle painting production, including:

[0047] A fixed frame 1 has symmetrical sliding grooves 2 inside the fixed frame 1. Sliding rods 3 are slidably installed in both sliding grooves 2. One end of each sliding rod 3 passes through one side of the two sliding grooves 2 and is fixedly installed with the same movable frame 4. A rotating shaft 9 is rotatably installed at the bottom of the movable frame 4. Both ends of the rotating shaft 9 are fixedly installed with power wheels 10.

[0048] A drive assembly is located within one of the sliding grooves 2 and is used to drive one of the sliding rods 3 to move.

[0049] The power assembly is located on the movable frame 4 and is used to drive the rotating shaft 9 to rotate;

[0050] Two rotating frames 7 are symmetrically mounted at the bottom of the fixed frame 1. A directional wheel 8 is rotatably mounted inside the rotating frame 7. A hydraulic cylinder 16 is fixedly mounted on the fixed frame 1. A compression plate 17 is fixedly mounted at the output end of the hydraulic cylinder 16. A rubber block 18 is fixedly mounted on the top of the compression plate 17. A hydraulic cylinder 29 is symmetrically fixedly mounted on the movable frame 4. A compression plate 20 is fixedly mounted at the output end of the hydraulic cylinder 29. A rubber block 21 is fixedly mounted on the top of the compression plate 20.

[0051] In operation, the operator first moves one of the sliding rods 3 according to the length of the bus using the drive assembly. The movement of the sliding rod 3 moves the moving frame 4, which in turn moves the other sliding rod 3. Simultaneously, the movement of the moving frame 4 rotates the two power wheels 10 until the moving frame 4 is moved to the appropriate position and stops. At this point, the operator can push the entire device under the bus. Then, the operator activates hydraulic cylinder 16 and two hydraulic cylinders 19. The output shaft of hydraulic cylinder 16 moves the extrusion plate 17 upward, which then presses against the bottom of the bus via rubber block 18. At the same time, the output shafts of the two hydraulic cylinders 19 move the two extrusion plates 20 upward, which then press against the bottom of the bus via rubber block 21. Under the pressure of the rubber blocks 21 and 18, the bus can be lifted, ensuring that buses of different lengths can be lifted. Furthermore, no other tools are needed to adjust the extension length of the moving frame 4, making it convenient and quick.

[0052] Subsequently, the power assembly drives the rotating shaft 9 to rotate, which in turn drives the two power wheels 10 to rotate. The rotation of the two power wheels 10 drives the entire device to move, making it easier for personnel to move the bus. When a turn is needed, the personnel can rotate the fixed frame 1. At this time, the two rotating frames 7 will rotate at the bottom of the fixed frame 1. The rotation of the rotating frames 7 will drive the steering wheels 8 to rotate, thereby turning the vehicle. This ensures that the entire device does not need to be moved with the help of other trailers when in use, making it convenient for short-distance transfer of the bus.

[0056] Rotating handle 6 causes the threaded rod 5 to rotate. Under the action of the thread, the rotation of the threaded rod 5 causes one of the sliding rods 3 to move. The movement of the sliding rod 3 causes the moving frame 4 to move. The movement of the moving frame 4 causes the other sliding rod 3 to slide. At the same time, the movement of the moving frame 4 also causes the two drive wheels 10 to rotate until the moving frame 4 is moved to the appropriate position and stops. This ensures that buses of different lengths can be lifted. Moreover, no other tools are needed to adjust the extension length of the moving frame 4, which is convenient and quick.

[0073] This ensures that the overall device can operate more smoothly and that the sliding rod 3 will not fall out of the sliding groove 2.

[0074] Working principle: In use, the operator first rotates handle 6 according to the length of the bus. Rotating handle 6 will drive the threaded rod 5 to rotate.

At the same time, the output shafts of the two hydraulic cylinders 219 will drive the two extrusion plates 20 to move upward respectively. The two extrusion plates 20 will press against the bottom of the bus through two rubber blocks 21 respectively. Under the extrusion of the two rubber blocks 21 and rubber block 18, the bus can be lifted up, ensuring that buses of different lengths can be lifted up. Moreover, no other tools are needed during the adjustment of the extension length of the moving frame 4, which is convenient and quick.

[0075] Then, personnel can hold onto handrail 15 and start motor 12. The output shaft of motor 12 will drive bevel gear 13 to rotate.
