Description

Technical Field

[0001] This utility model relates to the field of K&C bench testing technology, specifically to a lifting device for automobile testing. Background Technology

[0002] When vehicles undergo K&C testing, they often need to be placed on a test bench. The lateral and longitudinal displacement space of the vehicle is limited. If only a gantry crane is used for the operation, passenger vehicles, due to their lighter weight and relatively smaller size, can be moved by the driver or lifted by the gantry crane. Relying on the flexibility of the vehicle for movement is more convenient.

[0003] Since K&C bench tests are generally conducted indoors, when commercial vehicles undergo K&C testing, if the vehicle body size and weight are large, it is basically impossible to move the vehicle by hoisting. This is because most overhead cranes have limited lifting capacity and indoor space is limited. Therefore, heavy vehicles can only be placed by the driver moving the vehicle. When the vehicle is already placed on the K&C bench and it is necessary to install bottom tooling or equipment, especially when there is insufficient space at the bottom, the vehicle cannot be moved effectively. Utility Model Content

[0004] In view of the above-mentioned problems in the existing technology, the technical problem to be solved by this utility model is that when the vehicle has been placed on the K&C stand and the bottom tooling or equipment needs to be installed, especially when the bottom space is insufficient, the vehicle cannot be moved effectively.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a lifting device for automobile testing, comprising:

[0006] Base;

[0007] Casters, a plurality of said casters are mounted below said base to move said base;

[0008] The mounting frame is vertically mounted on the base;

[0009] A jack, wherein the base of the jack is fixedly mounted on the base, and the piston rod of the jack passes through the mounting frame and is slidably mounted on the mounting frame; and

[0010] A cable tray contact block, which is mounted on the piston rod of the jack.

[0011] Preferably, the cable tray contact block is mounted on the piston rod of the jack via a lifting beam; the middle part of the lifting beam is vertically and fixedly connected to the piston rod of the jack; the cable tray contact block is mounted on the side of the lifting beam away from the jack, and the position of the cable tray contact block in the length direction of the lifting beam is adjustable.

[0012] Preferably, it also includes an adjusting block and a bolt; the bridge contact block is mounted on the lifting beam via the adjusting block; the bridge contact block is vertically fixed in the middle of the adjusting block; the adjusting block has a plug hole parallel to the bridge contact block; the lifting beam has multiple threaded holes evenly distributed along its length on the side away from the jack; the bolt passes through the plug hole and is threaded into the threaded hole.

[0013] Preferably, the insertion hole is elongated in the length direction of the adjusting block.

[0014] Preferably, it further includes: a lifting guide shaft; the lifting guide shaft is slidably connected to the mounting frame along the length of the jack, and one end of the lifting guide shaft is fixedly connected to the lifting beam.

[0015] Preferably, a buffer pad is installed on the side of the mounting frame near the lifting beam.

[0016] Preferably, the system further includes multiple fixed feet, which are evenly installed on the base. Each fixed foot includes a threaded rod and an abutment block. The threaded rod is vertically arranged, and one end of the threaded rod is threadedly connected to the base. The other end of the threaded rod is equipped with an abutment block, which is located on the side of the base near the caster.

[0017] Preferably, the threaded rod is ball-jointed to the abutment block.

[0018] Preferably, it also includes a triangular reinforcing piece, which is fixedly connected to the mounting frame and the base.

[0019] Preferably, hooks are installed on opposite sides of the mounting frame.

[0020] Compared with the prior art, the present invention has at least the following advantages:

[0021] 1. In this utility model, the driving jack moves, and the piston rod of the jack drives the bridge contact block to move, so that the bridge contact block abuts against the test vehicle, thereby supporting the vehicle. It can also be freely pushed back and forth by the casters on the base, which facilitates fine position adjustment according to actual needs. When installing clamps on vehicles, especially large and heavy commercial vehicles, during K&C operations, it provides key support for local or overall parts, making it convenient for workers to lift the vehicle and make fine adjustments to its position, which is conducive to improving the convenience of installation. Relying solely on moving the vehicle back and forth on the platform is inefficient, and the lifting capacity of the gantry crane is limited, making it impossible to lift medium and large vehicles and the process is cumbersome.

[0022] 2. In this utility model, by setting up the lifting beam, the position of the bridge contact block in the length direction of the lifting beam can be adjusted, thereby enabling the lifting of different vehicle models.

[0023] 3. In this utility model, the position of the bridging contact block is adjusted according to the vehicle's adjustment bridging contact block position, thereby adjusting the position of the adjusting block in the length direction of the lifting beam, so that the insertion hole on the adjusting block is aligned with the nearest threaded hole. Then, the end of the bolt is inserted into the insertion hole and the bolt is rotated so that the bolt end is threadedly connected to the threaded hole until the hexagonal end of the thread abuts against the side of the adjusting block. In this way, the position of the bridging contact block can be coarsely adjusted; the position of the bolt in the insertion hole can be adjusted in the length direction of the adjusting block, thereby finely adjusting the position of the bridging contact block.

[0024] 4. In this utility model, after the abutment block initially contacts the ground, the threaded rod can still rotate, thereby increasing the pressure between the abutment block and the ground and reducing the pressure between the caster and the ground, thus effectively preventing the caster from being crushed under pressure; and through the setting of the ball joint, the angle of the abutment block can also be adjusted, thereby ensuring that the abutment block fits the ground, thus adapting to uneven ground.

[0033] See also Figures 1-3The present invention provides an embodiment of a lifting device for automobile testing, comprising: a base 1, casters 2, a mounting frame 3, a jack 4, and a bridge contact block 5; multiple casters 2 are installed below the base 1 to drive the base 1 to move; the mounting frame 3 is vertically mounted on the base 1; the base of the jack 4 is fixedly mounted on the base 1, and the piston rod of the jack 4 passes through the mounting frame 3 and is slidably mounted on the mounting frame 3; the bridge contact block 5 is mounted on the piston rod of the jack 4; furthermore, it also includes a triangular reinforcing plate 14, which is fixedly connected to the mounting frame 3 and the base 1; the installation strength between the mounting frame 3 and the base 1 is improved by the triangular reinforcing plate 14; furthermore, hooks 15 are respectively installed on opposite sides of the mounting frame 3; the lifting device can be moved more conveniently by the hooks 15.

[0034] In practice, the jack 4 is driven to move, and the piston rod of the jack 4 drives the bridge contact block 5 to move so that the bridge contact block 5 abuts against the test vehicle, thereby supporting the vehicle. It can also be pushed back and forth freely by the casters 2 on the base, which facilitates fine position adjustment according to actual needs. When installing clamps on vehicles, especially large and heavy commercial vehicles, during K&C operations, it provides key support for local or overall parts, making it convenient for workers to lift the vehicle and make fine adjustments to its position, which helps to improve the convenience of installation. Relying solely on moving the vehicle back and forth on the platform is inefficient, and the lifting capacity of the gantry crane is limited, making it impossible to lift medium and large vehicles and the process is cumbersome.

[0035] See also Figures 1-3 In other embodiments, the bridge contact block 5 is mounted on the piston rod of the jack 4 via the lifting beam 6; the middle part of the lifting beam 6 is vertically and fixedly connected to the piston rod of the jack 4; the bridge contact block 5 is mounted on the side of the lifting beam 6 away from the jack 4, and the position of the bridge contact block 5 in the length direction of the lifting beam 6 is adjustable. In specific implementation, by setting the lifting beam 6, the position of the bridge contact block 5 in the length direction of the lifting beam 6 can be adjusted, thereby enabling the lifting of different vehicle models; furthermore, a buffer pad 11 is installed on the side of the mounting frame 3 near the lifting beam 6; thereby effectively reducing the impact of the lifting beam 6 on the mounting frame 3.

[0036] See also Figures 1-3In other embodiments, it also includes an adjusting block 7 and a bolt; the bridge contact block 5 is mounted on the lifting beam 6 via the adjusting block 7; the bridge contact block 5 is vertically fixed in the middle of the adjusting block 7; the adjusting block 7 has a plug hole 8 parallel to the bridge contact block; the lifting beam 6 has a plurality of threaded holes 9 evenly provided along its length on the side away from the jack 4; the bolt passes through the plug hole 8 and is threadedly connected to the threaded hole 9. In practice, the position of the bridging contact block is adjusted according to the vehicle's adjustment bridging contact block position, thereby adjusting the position of the adjusting block 7 along the length of the lifting beam 6. This aligns the insertion hole 8 on the adjusting block 7 with the nearest threaded hole 9. Then, the end of the bolt is inserted into the insertion hole 8 and rotated to make the bolt end threaded into the threaded hole 9 until the hexagonal end of the thread abuts against the side of the adjusting block 7. This achieves a coarse adjustment of the bridging contact block position. Furthermore, the insertion hole 8 is elongated along the length of the adjusting block 7, allowing adjustment of the bolt position within the insertion hole 8 along the length of the adjusting block 7. This fine-tunes the bridging contact block position, ensuring better contact between the upper end of the bridging contact block and the vehicle's bridge frame.

[0037] See also Figures 1-3 In other embodiments, it also includes: a lifting guide shaft 10; the lifting guide shaft 10 is slidably connected to the mounting frame 3 in the length direction of the jack 4, and one end of the lifting guide shaft 10 is fixedly connected to the lifting beam 6; by setting the lifting guide shaft 10, the lifting beam 6 can be guided, ensuring that the lifting beam 6 can move more smoothly.

[0038] See also Figures 1-3 In other embodiments, multiple fixed feet are also included, which are evenly installed on the base 1. Each fixed foot includes a threaded rod 12 and an abutment block 13. The threaded rod 12 is vertically arranged, with one end threadedly connected to the base 1, and the other end of the threaded rod 12 is fitted with the abutment block 13, which is located on the side of the base 1 near the caster 2. In specific implementation, the threaded rod 12 is rotated to adjust the position of the abutment block 13 in the height direction. Therefore, after the position of the base 1 is adjusted by the caster 2, the threaded rod 12 controls the abutment block 13 to abut against the ground, thereby fixing the position of the base 1.

[0039] See also Figures 1-3 In another embodiment, the threaded rod 12 is ball-jointed with the abutment block 13; this allows the threaded rod 12 to continue rotating after the abutment block 13 has made initial contact with the ground, thereby increasing the pressure between the abutment block 13 and the ground and reducing the pressure between the caster 2 and the ground, thus effectively preventing the caster 2 from being crushed under pressure; and the ball joint also allows the angle of the abutment block 13 to be adjusted, thereby ensuring that the abutment block 13 fits the ground, thus adapting to uneven ground.
