Description

Technical Field

[0001] This application relates to the field of vehicle processing equipment, and more particularly to a lifting device for vehicle processing. Background Technology

[0002] In related technologies, the production of cargo boxes for pickup trucks involves first assembling the cargo box frame; then, welding is required to the bottom of the cargo box and to weld corresponding components onto it. In the cargo box production workshop, two scissor lift platforms are typically installed at intervals. These two platforms support opposite sides of the cargo box bottom and lift it, facilitating the welding process at the bottom.

[0003] Regarding the aforementioned technologies, two scissor lift platforms support both sides of the cargo box and lift it. During this process, the two scissor lift platforms operate independently, maintaining a large working space at the bottom of the cargo box. However, it is difficult to maintain consistent lifting speed and height between the two scissor lift platforms, affecting the stability of the cargo box. Furthermore, when both scissor lift platforms have clamps holding the sides of the cargo box, the cargo box is prone to being stretched and deformed, indicating areas for improvement. Summary of the Invention

[0004] In order to improve the problems in related technologies where two scissor lift platforms are used to lift the cargo box, it is difficult to keep the lifting speed and height of the two scissor lift platforms in a consistent manner, which affects the stability of the cargo box placement. Furthermore, when there are clamps on both sides of the cargo box on both scissor lift platforms, the cargo box is easily pulled and deformed. This application provides a lifting device for vehicle processing.

[0005] This application provides a lifting device for vehicle processing, which adopts the following technical solution:

[0006] A lifting device for vehicle processing includes a mounting frame, which is horizontal. Two mounting frames are arranged parallel to each other along their width. Lifting frames are raised and lowered on both mounting frames. Each mounting frame is provided with a linkage mechanism for driving the corresponding lifting frame to rise and fall. A synchronization mechanism is also provided on the mounting frame. Both linkage mechanisms are drivenly connected to the synchronization mechanism. The synchronization mechanism is located on one side of the mounting frame along its length. A driving component is also provided on the mounting frame. The driving component is drivenly connected to the synchronization mechanism and drives the synchronization mechanism and the linkage mechanism.

[0007] By adopting the above technical solution, in practical applications, the two sides of the cargo box can be respectively mounted on two lifting frames. A drive component drives a synchronization mechanism, which in turn drives two linkage mechanisms to operate synchronously. The two synchronization mechanisms then synchronously drive the two lifting frames to rise. This method helps ensure consistency in the lifting speed and height of the two lifting frames and helps guarantee the stability of the cargo box on the two lifting frames. When clamps are present on both lifting frames to hold the sides of the cargo box, the occurrence of stretching and deformation of the cargo box can be reduced.

[0008] Preferably, both linkage mechanisms include linkage brackets, both linkage brackets are slidably mounted on the mounting frame along the length of the mounting frame, both lifting frames are slidably mounted on the mounting frame in the vertical direction, both linkage brackets have guide ramps on their upper sides, the two guide ramps are parallel to each other, and both guide ramps are inclined upwards along the length of the mounting frame; both lifting frames have abutment members on their lower sides for respectively abutting against the corresponding guide ramps, and the driving component and the synchronization mechanism cooperate to drive the two linkage brackets to reciprocate.

[0009] By adopting the above technical solution, in practical applications, the two linkage brackets are driven to slide back and forth by the cooperation of the drive component and the synchronization mechanism, and the two lifting frames are driven to slide vertically by the cooperation of the guide inclined surface and the abutment part, which helps to ensure the stability of the lifting of the two lifting frames.

[0010] Preferably, the abutting member is an abutting wheel.

[0011] By adopting the above technical solution, the abutment wheel rolls on the guide slope, which helps to improve the convenience of driving the lifting frame to rise and fall.

[0012] Preferably, the linkage bracket is provided with support planes on both the upper and lower sides of the guide slope, and the two support planes are respectively connected to the upper and lower edges of the guide slope.

[0013] By adopting the above technical solution, when the lifting frame is at its highest and lowest points, the abutment can abut against the supporting plane, which helps to ensure the stability of the lifting frame.

[0014] Preferably, the mounting bracket is rotatably provided with support wheels. A set of support wheels is provided below the linkage bracket and on both sides of the linkage bracket in the width direction of the mounting bracket. Each set of support wheels includes at least two support wheels arranged along the length direction of the mounting bracket. The support wheel located below the linkage bracket abuts against the lower side of the linkage bracket, and the support wheels located on opposite sides of the linkage bracket abut against the corresponding side of the linkage bracket.

[0015] The linkage bracket includes a stabilizing rod, the length direction of which is parallel to the length direction of the mounting frame. A limit wheel is also rotatably mounted on the mounting frame, and the limit wheel abuts against the upper side of the stabilizing rod from top to bottom.

[0016] One guide ramp is provided on each of the two sides along the length of the stabilizer bar.

[0017] By adopting the above technical solution, the cooperation of support wheels and limit wheels helps to ensure the convenience and stability of the sliding of the linkage bracket.

[0018] Preferably, the synchronization mechanism includes a synchronization shaft, a swing frame, and a hinge rod. The synchronization shaft is located on one side of the mounting frame along its length, and its axis is set along the width of the mounting frame. The two ends of the synchronization shaft are rotatably mounted on two mounting frames, respectively. One side of the swing frame is fixed to the synchronization shaft, and the other side of the swing frame is hinged to one end of the hinge rod. The end of the hinge rod away from the swing frame is hinged to one end of the linkage bracket, and both the swing frame and the hinge rod correspond one-to-one with the linkage bracket.

[0019] By adopting the above technical solution, the synchronization of the two linkage supports is ensured by the cooperation of the synchronous shaft, the swing frame and the hinge rod, and the consistency of the lifting speed and height of the two lifting frames is also ensured.

[0020] Preferably, the driving component includes a driving cylinder, the cylinder body of the driving cylinder is hinged to the mounting bracket, the piston rod axis of the driving cylinder is arranged along the length direction of the mounting bracket, and the end of the piston rod of the driving cylinder is hinged to the linkage bracket.

[0021] By adopting the above technical solution, in practical applications, the drive cylinder pushes the linkage bracket, and the hinge rod pushes the synchronous shaft to rotate, so that the two linkage brackets can move synchronously, realizing the synchronous drive operation of the two lifting frames.

[0022] Preferably, the driving component further includes an electric cylinder, the cylinder body of which is hinged to another mounting bracket, the axis of the telescopic rod of the electric cylinder is arranged along the length direction of the mounting bracket, and the end of the telescopic rod of the electric cylinder is hinged to a corresponding linkage bracket.

[0023] By adopting the above technical solution, the telescopic rod extended by the electric cylinder can be stopped at any time, ensuring good stability and giving the lifting frame stability at the corresponding height.

[0024] Preferably, the hinge rod includes two threaded sleeves and a screw located between the two threaded sleeves. The two threaded sleeves are respectively hinged to the swing frame and the linkage bracket. The threads on both sides of the screw are arranged in opposite directions. The two ends of the screw are respectively inserted into the two threaded sleeves and respectively threadedly connected to the two threaded sleeves.

[0025] By adopting the above technical solution, in practical applications, if it is necessary to make the height of one lifting frame lower than that of the other, the operator can rotate the screw to make the two threaded sleeves move closer or further apart, and make the lengths of the two hinged rods inconsistent. When the drive component drives the synchronization mechanism and the linkage mechanism to move, the initial positions of the two linkage brackets are different due to the different lengths of the two hinged rods. At this time, the two linkage brackets slide and drive the two lifting frames to rise and fall. When the drive of the lifting frames is stopped, the two lifting frames will be at different heights, which helps to improve the applicability of the lifting equipment.

[0026] Preferably, the synchronous shaft includes two end rods and an intermediate rod located between the two end rods. The intermediate rod and the two end rods are coaxially arranged. Each of the two end rods has a socket on the side that is close to each other. The intermediate rod and the socket are both hexagonal in shape. The two ends of the intermediate rod are respectively inserted into the two sockets and slidably connected to the corresponding end rods.

[0027] Both of the aforementioned insertion holes are provided with elastic elements, each of which abuts against the corresponding middle rod end and the bottom wall of the insertion hole. The opposite ends of the two end rods are respectively rotatably mounted on two mounting brackets.

[0028] The two mounting brackets are provided with a base frame on their lower side. Both mounting brackets are slidably mounted on the base frame along their width direction. The base frame is also provided with a pushing component for driving the two base frames to move closer or further apart.

[0029] By adopting the above technical solution, in practical application, the pushing component pushes the two base frames closer or further apart; at the same time, as the two base frames move closer or further apart, the middle rod will slide relative to the two end rods under the action of the two elastic elements, and can always be in the middle position of the two end rods, thereby realizing the adjustment of the distance between the two lifting frames and maintaining the synchronous driving operation of the two lifting frames.

[0030] Preferably, both lifting frames are slidably mounted on the mounting frame in a vertical direction. Both linkage mechanisms include a linkage shaft, a linkage gear, and a linkage rack. Both linkage racks are vertically arranged and fixed to the two lifting frames respectively. The two linkage shafts are rotatably mounted on the two mounting frames respectively. The two linkage gears are coaxially fixed to the two linkage shafts respectively. The two linkage gears mesh with the corresponding linkage racks respectively. The driving component and the synchronization mechanism cooperate to synchronously drive the two linkage shafts to rotate.

[0031] By adopting the above technical solution, in practical applications, the two linkage shafts are driven to rotate by the drive component and the synchronization mechanism, and the two lifting frames are driven to slide vertically by the linkage gear and the linkage rack, which helps to ensure the stability of the lifting of the two lifting frames.

[0032] Preferably, the synchronization mechanism includes a synchronization rod, with both ends of the synchronization rod rotatably mounted on two mounting brackets. Both ends of the synchronization rod are coaxially fixed with a first bevel gear, and the ends of the two linkage shafts opposite to the linkage gears are coaxially fixed with a second bevel gear. The two first bevel gears mesh with the two second bevel gears respectively.

[0033] The driving component includes a geared motor, which is connected to the synchronizing rod and drives the synchronizing rod to rotate.

[0034] By adopting the above technical solution, the synchronous rod is driven to rotate by the geared motor, and the two linkage shafts are driven to rotate synchronously through the cooperation of two sets of first bevel gears and second bevel gears, thereby synchronously driving the two lifting frames to rise and fall, specifically realizing the synchronous lifting and falling of the two lifting frames.

[0042] The present application will be further described in detail below with reference to the accompanying drawings.

[0043] In related technologies, welding the bottom of the cargo box can be done manually or by using a robotic arm.

[0044] This application discloses a lifting device for vehicle processing.

[0045] Example 1:

[0046] Reference Figure 1 and Figure 2 A vehicle handling lifting device includes a horizontally arranged mounting frame 1, with two mounting frames 1 spaced parallel to each other along their width, and the two mounting frames 1 are fixed relative to each other on the ground. Lifting frames 2 are vertically slidably mounted on each of the two mounting frames 1. Each mounting frame 1 is equipped with a linkage mechanism 3 for driving the corresponding lifting frame 2 to rise and fall. A synchronization mechanism 4 is also provided on the mounting frame 1. Both linkage mechanisms 3 are drively connected to the synchronization mechanism 4. The synchronization mechanism 4 is located on the outer side of the mounting frame 1 along its length. A drive component 5 is also provided on the mounting frame 1, which is drively connected to the synchronization mechanism 4 and drives both the synchronization mechanism 4 and the linkage mechanism 3. In practical application, the drive component 5 and the synchronization mechanism 4 work together to synchronously drive the two linkage mechanisms 3, which in turn drive the two lifting frames 2 to rise and fall, thereby stably lifting and lowering the cargo box.

[0047] Mounting frame 1 is vertically fixed with a fixing column 11. A linear guide rail 12 is slidably connected between the lower side of the lifting frame 2 and the side wall of the fixing column 11. In this embodiment, the track of the linear guide rail 12 can be vertically fixed to the fixing column 11, and the slider of the linear guide rail 12 can be fixed to the lower side of the lifting frame 2. A cover can be set on the fixing column 11 to cover the linear guide rail 12 and protect it. There is one fixing column 11 on each side of the mounting frame 1 along its length. The linear guide rail 12 corresponds to the fixing column 11 one by one, and both the fixing column 11 and the linear guide rail 12 are correspondingly set to the lifting frame 2.

[0048] Each linkage mechanism 3 includes a linkage bracket 31, the length of which is parallel to the length of the mounting frame 1, and the linkage bracket 31 is located below the lifting frame 2. Support wheels 13 are rotatably mounted on the mounting frame 1. A set of support wheels 13 is located below the linkage bracket 31 and on both sides of the linkage bracket 31 in the width direction of the mounting frame 1. Each set of support wheels 13 includes at least two support wheels 13 arranged along the length of the mounting frame 1. The support wheel 13 located below the linkage bracket 31 abuts against the lower side of the linkage bracket 31, and the support wheels 13 located on opposite sides of the linkage bracket 31 abut against the corresponding sides of the linkage bracket 31. The linkage bracket 31 includes a stabilizing rod 311, the length of which is parallel to the length of the mounting frame 1. A limiting wheel 14 is also rotatably mounted on the mounting frame 1, abutting against the upper side of the stabilizing rod 311 from top to bottom. With the cooperation of the limiting wheel 14 and the three sets of support wheels 13, the linkage bracket 31 can slide relatively stably on the mounting frame 1.

[0049] Meanwhile, a guide ramp 312 is provided on the upper side of the linkage bracket 31, and the guide ramp 312 is inclined upward along the length direction of the mounting frame 1; the linkage bracket 31 is provided with support planes 313 on both the upper and lower sides of the guide ramp 312, and the two support planes 313 are respectively connected to the upper and lower edges of the guide ramp 312. A stop member is provided on the lower side of the lifting frame 2, and the stop member is a stop wheel 21. The stop wheel 21 is rotatably set on the lower side of the lifting frame 2. When the lifting frame 2 is not lifted, the stop wheel 21 abuts against the support plane 313 located on the lower side; when the lifting frame 2 is lifted, the stop wheel 21 abuts against the guide ramp 312; when the lifting frame 2 is in the lifted state, the stop wheel 21 can abut against the support plane 313 located on the upper side. Furthermore, there is one guide ramp 312 on each side of the linkage bracket 31 along its length, the support plane 313 is correspondingly set with the guide ramp 312, the linkage bracket 31 is correspondingly set with the linkage mechanism 3, and all the guide ramps 312 are parallel to each other. The support wheel 13, the limit wheel 14, and the abutment wheel 21 are all correspondingly set with the linkage bracket 31.

[0050] The synchronization mechanism 4 includes a synchronization shaft 41, a swing frame 42, and a hinge rod 43. The synchronization shaft 41 is located on the outer side of one side of the mounting frame 1 along its length, and its axis is set along the width of the mounting frame 1. Both ends of the synchronization shaft 41 are rotatably mounted on two mounting frames 1 respectively. One side of the swing frame 42 is fixed to the synchronization shaft 41, and the other side of the swing frame 42 is hinged to one end of the hinge rod 43. The end of the hinge rod 43 facing away from the swing frame 42 is hinged to one end of the linkage bracket 31, and both the swing frame 42 and the hinge rod 43 correspond one-to-one with the linkage bracket 31.

[0051] The driving component 5 includes a driving cylinder 51, which is located on the side of the linkage bracket 31 opposite to the synchronous shaft 41. The cylinder body of the driving cylinder 51 is hinged to the mounting bracket 1, and the piston rod axis of the driving cylinder 51 is arranged along the length direction of the mounting bracket 1. The end of the piston rod of the driving cylinder 51 is hinged to the corresponding linkage bracket 31, and the driving cylinder 51 corresponds one-to-one with the linkage bracket 31. In this embodiment, a protective cover can be provided on the mounting bracket 1 to cover the driving cylinder 51 for protection.

[0052] In addition, it should be noted that in actual use, clamps for fixing the cargo box can be set on the two lifting frames 2 to fix the cargo box and ensure its stability. Furthermore, based on the synchronization mechanism 4, the synchronization of the two lifting frames 2 can reduce the occurrence of cargo box deformation caused by the inconsistency in the lifting speed and height of the two lifting frames 2.

[0053] The implementation principle of a vehicle processing lifting device according to an embodiment of this application is as follows: In practical application, the two sides of the cargo box can be respectively mounted on two lifting frames 2; then, two drive cylinders 51 drive two linkage brackets 31 to slide, and with the cooperation of the guide inclined surface 312 and the abutment wheel 21, the two lifting frames 2 are lifted; at the same time, with the cooperation of the hinge frame, the swing frame 42 and the synchronous shaft 41, the movement of the two linkage brackets 31 is kept synchronized. In this way, it helps to ensure the consistency of the lifting speed and height of the two lifting frames 2, and helps to ensure the stability of the cargo box on the two lifting frames 2.

[0054] Example 2:

[0055] Reference Figure 3 The difference between this embodiment and Embodiment 1 is that:

[0056] A sliding column 15 is vertically fixed between the top of the fixed column 11 and the mounting frame 1. A sliding sleeve 22 is fixed on the lifting frame 2. The sliding sleeve 22 is fitted onto the sliding column 15 and slides in cooperation with the sliding column 15.

[0057] Each linkage mechanism 3 includes a linkage shaft 32, a linkage gear 33, and a linkage rack 34. The linkage rack 34 is vertically arranged and fixed to the middle of the lifting frame 2. The linkage shaft 32 is rotatably mounted on the mounting frame 1. The linkage gear 33 is coaxially fixed on the linkage shaft 32 and meshes with the linkage rack 34. The linkage shaft 32, linkage gear 33, and linkage rack 34 are all corresponding to the two linkage mechanisms 3.

[0058] The synchronization mechanism 4 includes a synchronization rod 44, with both ends of the synchronization rod 44 rotatably mounted on two mounting brackets 1. A first bevel gear 441 is coaxially fixed to both ends of the synchronization rod 44. A second bevel gear 321 is coaxially fixed to the ends of the two linkage shafts 32 opposite to the corresponding linkage gears 33. The first bevel gears 441 and the second bevel gears 321 are paired and meshed. The drive component 5 includes a geared motor 52, which is connected to the synchronization rod 44 and drives the synchronization rod 44 to rotate.

[0059] In practical applications, the geared motor 52 drives the synchronous rod 44 to rotate, and the two first bevel gears 441 cooperate with the two second bevel gears 321 respectively to synchronously drive the two linkage shafts 32 to rotate, thereby synchronously driving the two lifting frames 2 to rise and fall.

[0060] Example 3:

[0061] Reference Figure 4 and Figure 5 The difference between this embodiment and Embodiment 1 is that:

[0062] A base frame 6 is provided on the lower side of each of the two mounting brackets 1, and the base frame 6 is arranged along the length direction of the mounting bracket 1. A slide rail 61 is provided on the base frame 6 along its length direction. Double-sided wheels 16 are rotatably provided on the lower side of each of the two mounting brackets 1. The upper side of the slide rail 61 is embedded between the two side plates of the double-sided wheel 16, and two slide rails 61 are arranged parallel to each other along the length direction of the mounting bracket 1. Two sets of double-sided wheels 16 are provided on each of the two mounting brackets 1 corresponding to the two slide rails 61. Each set of double-sided wheels 16 includes multiple double-sided wheels 16 spaced apart along the width direction of the mounting bracket 1.

[0063] The base frame 6 is also equipped with a pushing assembly 7 for driving the two base frames 6 to move closer or further apart. The pushing assembly 7 includes a lead screw 71 and a drive motor 72. The axis of the lead screw 71 is arranged along the length of the base frame 6, and the two ends of the lead screw 71 are respectively rotatably mounted on both sides of the base frame 6 along the length of the base frame 6. The threads on both sides of the lead screw 71 are oriented in the direction of the axis. The two sides of the lead screw 71 pass through the lower side of the two mounting brackets 1 respectively and are threadedly connected to the corresponding mounting brackets 1. The drive motor 72 is fixed on the base frame 6, and the output shaft of the drive motor 72 is coaxially fixed with one end of the lead screw 71.

[0064] The synchronous shaft 41 includes two end rods 411 and an intermediate rod 412 located between the two end rods 411. The intermediate rod 412 and the two end rods 411 are coaxially arranged. Each of the two end rods 411 has a socket 4111 on its side closest to each other. Both the intermediate rod 412 and the socket 4111 are hexagonal in shape. The two ends of the intermediate rod 412 are respectively inserted into the two sockets 4111 and slidably connected to the corresponding end rods 411. Each socket 4111 is provided with an elastic element, which is a compression spring 4112. Each compression spring 4112 is pressed against the end of the corresponding intermediate rod 412 and the bottom wall of the socket 4111. The opposite ends of the two end rods 411 are rotatably mounted on two mounting brackets 1.

[0065] In practical applications, the drive motor 72 drives the lead screw 71 to rotate, causing the two base frames 6 to move closer or further apart. Simultaneously, as the two base frames 6 move closer or further apart, the intermediate rod 412, under the action of the two elastic elements, will slide relative to the two end rods 411, and can always remain in the exact center position of the two end rods 411.

[0066] The two hinge rods 43 have the same structure. The structure of one of the hinge rods 43 will be described as an example. The hinge rod 43 includes two threaded sleeves 431 and a screw 432 located between the two threaded sleeves 431. The two threaded sleeves 431 are respectively hinged to the swing frame 42 and the linkage bracket 31. The threads on both sides of the screw 432 are arranged in opposite directions. The two ends of the screw 432 pass through the two threaded sleeves 431 and are threadedly connected to the two threaded sleeves 431 respectively.

[0067] The driving component 5 is an electric cylinder 53. The cylinder body of the electric cylinder 53 is hinged to any mounting bracket 1. The axis of the telescopic rod of the electric cylinder 53 is set along the length direction of the mounting bracket 1, and the end of the telescopic rod of the electric cylinder 53 is hinged to the corresponding linkage bracket 31. In actual use, if it is necessary to make the height of one lifting bracket 2 lower than that of the other lifting bracket 2, the operator can rotate the corresponding screw 432 to make the two corresponding threaded sleeves 431 move closer or further apart, and make the lengths of the two hinge rods 43 inconsistent. When the electric cylinder 53 drives the linkage bracket 31 and the synchronous shaft 41 to move, the initial positions of the two linkage brackets 31 are different because the lengths of the two hinge rods 43 are different. At this time, the two linkage brackets 31 slide and drive the two lifting brackets 2 to rise and fall. When the driving of the lifting brackets 2 is stopped, the two lifting brackets 2 will be at different heights.

[0068] Example 4:

[0069] See Figure 6The difference between this embodiment and Embodiment 1 is that the driving component 5 includes a driving cylinder 51 and an electric cylinder 53. The driving cylinder 51 is located on the side of the linkage bracket 31 opposite to the synchronous shaft 41. The cylinder body of the driving cylinder 51 is hinged to the mounting bracket 1, the piston rod axis of the driving cylinder 51 is arranged along the length direction of the mounting bracket 1, and the end of the piston rod of the driving cylinder 51 is hinged to the corresponding linkage bracket 31. The cylinder body of the electric cylinder 53 is hinged to another mounting bracket 1, the axis of the telescopic rod of the electric cylinder 53 is arranged along the length direction of the mounting bracket 1, and the end of the telescopic rod of the electric cylinder 53 is hinged to the corresponding linkage bracket 31.
