Description

Technical Field

[0001] This application relates to the field of vehicle conveying equipment technology, and in particular to a vehicle chassis lifting device. Background Technology

[0002] Chassis spreaders are primarily used for lifting and moving vehicle chassis or related components. During movement, the chassis spreader may tilt, requiring adjustment devices to correct its angle and restore the tilted chassis to its original position.

[0003] Existing chassis lifting device adjustment devices mostly use mechanical reset to adjust the relative horizontal plane of the chassis lifting device. They cannot adjust other tilt angles of the chassis lifting device. In addition, the adjustment accuracy of manual operation and mechanical reset is poor, and the operation efficiency is also relatively low. Utility Model Content

[0004] Therefore, it is necessary to provide a vehicle chassis hanger adjustment device that can automatically adjust and reset the chassis hanger, and improve adjustment accuracy and work efficiency.

[0005] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0006] A vehicle chassis hanger adjustment device, the vehicle chassis hanger adjustment device comprising:

[0007] The top plate is equipped with a driving mechanism;

[0008] The lifting device body is used to lift the vehicle chassis, and the lifting device body is equipped with an angle sensor, which is used to detect the tilt angle of the lifting device body relative to the horizontal plane and generate an adjustment signal;

[0009] The adjustment mechanism includes an adjustment plate, a counterweight box, and an air pump. The adjustment plate is mounted on the lifting device body and connected to the drive component to move under the drive component. The counterweight box is mounted on the adjustment plate, and the air pump is connected to the counterweight box and signal-connected to the angle sensor.

[0010] The air pump can be controlled to inflate the counterweight box according to the adjustment signal.

[0011] Understandably, this application uses an angle sensor to detect the tilt angle of the spreader body relative to the horizontal plane, generates a corresponding adjustment signal, and transmits it to the air pump. Upon receiving the adjustment signal, the air pump immediately inflates the counterweight box at the opposite tilt angle of the spreader body. The weight of the counterweight box then uses the adjustment disc to reset the tilted spreader body. This intelligent method of adjusting and resetting the spreader body tilted relative to the horizontal plane offers high precision and eliminates the need for manual operation, thereby improving operational accuracy and efficiency.

[0012] In one embodiment, the counterweight box includes a box body, a partition, a one-way valve, and an air outlet pipe. The partition is disposed inside the box body and divides it into at least two independently disposed counterweight chambers, one of which is connected to the air pump.

[0013] The one-way valve is installed on the partition plate and enables one-way communication between two adjacent counterweight chambers. The air outlet pipe is installed on the box body and is connected to the corresponding counterweight chamber.

[0014] Understandably, the one-way valve can control the air intake of each partition, and the air outlet pipe can control the air output of each counterweight chamber. By setting up the one-way valve and the air outlet pipe, the weight at the location of each counterweight chamber can be adjusted, thereby achieving precise counterweighting of the counterweight box and improving the accuracy of the tilt angle adjustment of the lifting device body relative to the horizontal plane.

[0015] In one embodiment, the number of counterweight boxes is set to multiple, and the multiple counterweight boxes are arranged at circumferential intervals along the adjustment plate.

[0016] Understandably, by setting up multiple counterweight boxes and arranging them at intervals along the circumference of the adjustment plate, angle adjustments can be made at multiple positions along the circumference of the adjustment plate. This allows the vehicle chassis lifting device to adjust and reset to various tilt angles, and further improves the reset accuracy of the lifting body.

[0017] In one embodiment, a pressure sensor is provided in the counterweight chamber to monitor the pressure value in the counterweight chamber and generate a pressure signal. An electric valve is provided in the air outlet pipe, and the pressure sensor is signal-connected to the electric valve to control the opening / closing of the electric valve according to the pressure signal.

[0018] Understandably, when the pressure sensor detects that the pressure in the counterweight chamber is too high, the electric valve can receive the signal and open, allowing the air outlet pipe to release air to reduce the pressure in the counterweight chamber. Conversely, it can close the electric valve to increase the pressure in the counterweight chamber. In this way, not only can the counterweight be accurately balanced and the resetting accuracy of the lifting device be improved, but the air pressure in the counterweight chamber can also be prevented from exceeding its maximum bearing pressure, thereby eliminating safety hazards.

[0019] In one embodiment, an image acquisition device is provided inside the counterweight cavity, and the image acquisition device is used to acquire images inside the counterweight cavity.

[0020] Understandably, the image acquisition device can capture images of the inside of the counterweight chamber in real time, making it easier for operators to monitor the wear and tear of the internal parts of the counterweight box and to carry out timely maintenance and repairs.

[0021] In one embodiment, the adjustment plate is provided with an auxiliary rod, one end of which is fixedly connected to the adjustment plate, and the other end is slidably and limit-connected to the top plate.

[0022] Understandably, the auxiliary rod is designed to lift the adjustment plate, bear part of its weight, and prevent the overall adjustment mechanism from being damaged due to excessive load. Furthermore, the sliding limit connection to the top plate allows it to share the weight of the adjustment plate without affecting its movement.

[0023] In one embodiment, the auxiliary rods are configured as multiple rods, and the multiple auxiliary rods are spaced apart circumferentially along the adjustment disc;

[0024] A sliding groove is provided on the side of the top plate facing the adjustment plate, and the auxiliary rod is limited and slidably installed in the sliding groove at the end away from the adjustment plate;

[0025] As the driving component drives the adjustment disc to move relative to the top plate, the auxiliary rod can slide within the sliding groove.

[0026] Understandably, multiple auxiliary rods are arranged circumferentially to bear the force on the adjustment plate at multiple angles, preventing the adjustment plate from tilting due to the force itself, thereby reducing the probability of the spreader body tilting due to the vehicle chassis spreader adjustment device.

[0027] In one embodiment, the adjustment plate is provided with an elastic element, one end of which is detachably connected to the adjustment plate and the other end is detachably connected to the top plate.

[0028] Understandably, the elastic element has the function of elastic buffering. By connecting the adjusting plate and the top plate through the elastic element, it can prevent the adjusting plate from falling directly due to excessive force and causing damage. The connection is detachable so as not to affect the rotation of the adjusting plate relative to the top plate.

[0029] In one embodiment, connecting blocks are provided at both ends of the elastic element, and threaded rods are provided on the connecting blocks. The threaded rods are threadedly connected to the adjusting disc and the top plate, respectively.

[0030] In one embodiment, the number of elastic elements is set to a plurality, and the plurality of elastic elements are arranged at circumferential intervals along the adjustment disc.

[0031] Compared to existing technologies, the vehicle chassis spreader adjustment device uses an angle sensor to detect the tilt angle of the spreader body relative to the horizontal plane, generates a corresponding adjustment signal, and transmits it to the air pump. Upon receiving the adjustment signal, the air pump immediately inflates the counterweight box at the opposite tilt angle of the spreader body. The weight of the counterweight box then uses the adjustment disc to reset the tilted spreader body. This intelligent method of adjusting and resetting the spreader body relative to the horizontal plane offers high precision and eliminates the need for manual operation, making worker operations accurate and efficient.

The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0043] Please see Figures 1 to 2 This application provides a vehicle chassis lifting device 100, which is mainly used for lifting vehicle chassis such as automobiles and adjusting and resetting vehicle chassis that are tilted relative to the horizontal plane during the lifting process.

[0044] like Figures 1 to 4As shown, the vehicle chassis lifting device 100 includes a top plate 10, a lifting body 20, and an adjustment mechanism 30. A drive component 11 is provided on the top plate 10. The lifting body 20 is used to lift the vehicle chassis, and an angle sensor 21 is provided on the lifting body 20. The angle sensor 21 is used to detect the tilt angle of the lifting body 20 relative to the horizontal plane and generate an adjustment signal. The adjustment mechanism 30 includes an adjustment plate 31, a counterweight box 32, and an air pump 33. The adjustment plate 31 is installed on the lifting body 20 and connected to the drive component 11 so that it can move under the drive of the drive component 11. The counterweight box 32 is installed on the adjustment plate 31, and the air pump 33 is connected to the counterweight box 32 and is signal-connected to the angle sensor 21. The air pump 33 can control its inflation of the counterweight box 32 according to the adjustment signal. It is understandable that during the lifting process, the vehicle chassis may rotate horizontally and tilt relative to the horizontal plane due to its movement, requiring adjustment to ensure assembly accuracy. However, existing adjustment devices can only rotate the vehicle chassis horizontally or move it vertically relative to the horizontal plane. The tilt angle relative to the horizontal plane can only be adjusted manually, resulting in poor adjustment accuracy and low work efficiency. Therefore, this application incorporates an angle sensor 21 and an adjustment mechanism 30. The angle sensor 21 detects the tilt angle of the lifting body 20 relative to the horizontal plane, generates a corresponding adjustment signal, and transmits it to the air pump 33. Upon receiving the adjustment signal, the air pump 33 immediately inflates the counterweight box 32, using the weight of the counterweight box 32 to cause the adjustment plate 31 to reset the tilted lifting body 20. This intelligent method of adjusting and resetting the tilted lifting body 20 relative to the horizontal plane offers high accuracy and eliminates the need for manual operation, thereby improving the accuracy and efficiency of vehicle chassis lifting operations.

[0045] Here, the driving component 11 can be a servo motor, which can be mounted on the top plate 10. A driving rod is mounted on the output shaft of the servo motor. The driving rod is located on the side of the top plate 10 near the adjustment mechanism 30 and is fixedly connected to the adjustment plate 31, so that the driving rod can drive the adjustment plate 31 to rotate on the horizontal plane to adjust the position of the lifting device body 20 on the horizontal plane.

[0046] like Figure 2 and Figure 3 As shown, an auxiliary rod 311 is provided on the adjustment plate 31. One end of the auxiliary rod 311 is fixedly connected to the adjustment plate 31, and the other end is slidably and limitedly connected to the top plate 10, meaning that the auxiliary rod 311 cannot be detached from the top plate 10. In this way, the adjustment plate 31 can be lifted by the auxiliary rod 311, so as to share the force borne by the adjustment plate 31 and avoid the overall load of the adjustment mechanism 30 being too heavy and damaged. The sliding and limited connection to the top plate 10 is to prevent it from affecting the movement of the adjustment plate 31 on the horizontal plane.

[0047] Preferably, multiple auxiliary rods 311 are configured, and the multiple auxiliary rods 311 are spaced apart circumferentially along the adjusting plate 31. A sliding groove (not shown) is opened on the side of the top plate 10 facing the adjusting plate 31. The end of the auxiliary rod 311 away from the adjusting plate 31 is limited and slidably installed in the sliding groove. As the driving member 11 drives the adjusting plate 31 to move relative to the top plate 10, the auxiliary rod 311 can slide in the sliding groove. It can be understood that the multiple auxiliary rods 311 are arranged circumferentially so as to bear the force on the adjusting plate 31 from different directions, avoid the adjusting plate 31 from tilting due to the force, and thus reduce the probability of the lifting device body 20 tilting due to the vehicle chassis lifting device.

[0048] Here, the auxiliary rods 311 can be configured as four, six, or eight, and are not limited to these. The specific number of auxiliary rods 311 can be determined according to the actual situation such as the size of the adjustment plate 31 and the weight of the vehicle chassis. In this embodiment, six auxiliary rods 311 are configured. Furthermore, the six auxiliary rods 311 are arranged on the adjustment plate 31 in a uniformly spaced manner.

[0049] In one embodiment, an elastic element 312 is provided on the adjustment plate 31. One end of the elastic element 312 is detachably connected to the adjustment plate 31, and the other end is detachably connected to the top plate 10. This allows the elastic element 312 to buffer the impact, preventing the adjustment plate 31 from being damaged due to excessive force or weight. Furthermore, the detachable connection ensures that the elastic element 312 does not affect the rotation of the adjustment plate 31 relative to the top plate 10 on the horizontal plane, thereby enabling horizontal angle adjustment of the vehicle chassis.

[0050] Furthermore, connecting blocks 3121 are provided at both ends of the elastic element 312, and threaded rods 3122 are provided on the connecting blocks 3121. The threaded rods 3122 are threadedly connected to the adjusting plate 31 and the top plate 10 respectively.

[0051] Preferably, the number of elastic elements 312 is set to multiple, and the multiple elastic elements 312 are arranged at intervals along the circumferential direction of the adjusting disc 31.

[0052] Here, the number of elastic elements 312 can be set to three, five, six, or other numbers, and is not limited to these. The specific number of elastic elements 312 can be determined according to the actual situation. In this embodiment, the number of elastic elements 312 is set to three, and the three elastic elements 312 can be arranged on the adjusting plate 31 in a uniformly spaced manner.

[0053] Please refer to Figure 3 and Figure 4The counterweight box 32 includes a box body 321, a partition 322, a one-way valve 323, and an air outlet pipe 324. The partition 322 is disposed inside the box body 321 and divides it into at least two independently disposed counterweight chambers 325. One of the counterweight chambers 325 is connected to the air pump 33. The one-way valve 323 is installed on the partition 322 and enables one-way communication between two adjacent counterweight chambers 325. The air outlet pipe 324 is disposed in correspondence with the counterweight chambers 325 and is installed on the box body 321 and is connected to the corresponding counterweight chamber 325. Understandably, the one-way valve 323 can control the air intake of each partition 322, thereby controlling the air intake of each counterweight chamber 325, and the air outlet pipe 324 can control the air output of each counterweight chamber 325. Through the one-way valve 323 and the air outlet pipe 324, the weight of the corresponding counterweight chamber 325 can be controlled, so as to achieve precise counterweighting of the counterweight box 32, and adjust the accuracy of the tilt angle of the lifting device body 20 relative to the horizontal plane.

[0054] In one embodiment, the number of counterweight boxes 32 is set to multiple, and the multiple counterweight boxes 32 are arranged at intervals along the circumference of the adjustment plate 31. In this way, when the lifting device body 20 tilts relative to the horizontal plane, the air pump 33 on the corresponding counterweight box 32 receives a signal and inflates the counterweight box 32 to accurately reset the lifting device body 20; and combined with the aforementioned counterweight cavity 325, the counterweight area is divided into multiple parts, further making the reset of the lifting device body 20 more accurate.

[0055] Specifically, the number of counterweight boxes 32 can be set to three, four, or six, and is not limited to these; the specific number of counterweight boxes 32 can be determined according to the actual situation. In this embodiment, the number of counterweight boxes 32 is set to four.

[0056] Furthermore, a pressure sensor 3251 is installed inside the counterweight chamber 325. The pressure sensor 3251 monitors the pressure value inside the counterweight chamber 325 and generates a pressure signal. An electric valve (not shown) is installed inside the air outlet pipe 324. The pressure sensor 3251 is signal-connected to the electric valve and is used to control the opening / closing of the electric valve according to the pressure signal. Thus, when the pressure sensor 3251 detects that the pressure inside the counterweight chamber 325 is too high, the electric valve can receive the signal and open, allowing the air outlet pipe 324 to release air to reduce the pressure inside the counterweight chamber 325. Conversely, it can close the electric valve to increase the pressure inside the counterweight chamber 325. In this way, not only can the counterweight be accurately balanced, improving the reset accuracy of the lifting device body 20, but it can also prevent the air pressure inside the counterweight chamber 325 from exceeding its maximum bearing pressure, thereby eliminating safety hazards.

[0057] Preferably, an image acquisition device 3252 is also provided inside the counterweight cavity 325. The image acquisition device 3252 is used to acquire images inside the counterweight cavity 325 so that operators can understand the wear and tear of the parts inside the counterweight cavity 325 and carry out timely maintenance and repair.

[0058] Here, the image acquisition device 3252 can be an embedded camera or an infrared sensor, etc., which can acquire images inside the counterweight cavity 325 using optical imaging technology and electronic processing technology, and can be connected to an external display device via wires or Bluetooth, so that operators can more easily grasp the situation inside the counterweight cavity 325.

[0059] The working process of the vehicle chassis suspension adjustment device 100 is described below:

[0060] When the lifting device body 20 tilts relative to the horizontal plane, the angle sensor 21 detects the signal and generates a corresponding adjustment signal, which is transmitted to the air pump 33. After receiving the signal, the air pump 33 immediately inflates the corresponding counterweight box 32. The tilt angle of the lifting device body 20 is adjusted and reset by the weight change of the counterweight box 32. During this process, the operator can change the inflation volume of the multiple counterweight chambers 325 divided by the partition 322 by controlling the opening or closing of the one-way valve 323 and the air outlet pipe 324 according to the actual situation (tilt angle of the lifting device body 20). Thus, by changing the weight of different counterweight chambers 325, the lifting device body 20 can be accurately reset.

[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
