Description

Technical Field

[0001] The invention relates to the technical field of automobile testing tools, in particular to a vehicle chassis lifting device. Background Art

[0002] Chassis (Heading wall) is an important part of the overall structure of the car. Chassis refers to the combination of the transmission system, running system, steering system and braking system on the car. It supports and installs the car engine and its various components and assemblies to form the overall shape of the car, bear the engine power and ensure normal driving.

[0003] At present, when workers inspect the chassis of a car, they need to use a lifting device to lift the car so that the workers can lie in the gap between the car and the ground to inspect the chassis of the car.

[0004] In the prior art, lifting operations are usually performed by hydraulic cylinders, which are mostly arranged longitudinally. However, in the long run, this arrangement will have an adverse effect on the service life of the hydraulic cylinders.

[0005] Therefore, it is necessary to design a vehicle chassis lifting device with strong practicality. Summary of the invention

[0006] The object of the present invention is to provide a vehicle chassis lifting device to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: a vehicle chassis lifting device, comprising:

[0008] Guide rail plates 1, the number of which is four, and the four guide rail plates 1 are arranged longitudinally;

[0009] Among them, a mounting rod is fixedly installed between the guide rail plates 1 arranged at the front and rear positions, and a guide rail plate 2 is fixedly installed between the mounting rods;

[0010] A pressure plate is arranged above the second guide rail plate, and the pressure plate is connected to the second guide rail plate through a lifting assembly;

[0011] Wherein, the top surface of the pressure bearing plate has an L-shaped opening;

[0012] Auxiliary components are installed in the guide plate;

[0013] The pressure bearing plate is connected with a protection component.

[0014] According to the above technical solution, a mounting seat is fixedly installed at the bottom of the guide rail plate 1, and the mounting seat is fixed to the bottom surface by bolts. Through the setting of the mounting seat, the entire device can be stably installed on the bottom surface, which can ensure the stable lifting operation of the device and avoid causing danger.

[0015] According to the above technical solution, there are two lifting assemblies, which are symmetrically distributed on the left and right sides with the midline of the front side of the second guide plate as the symmetry axis. Through the opposing arrangement of the two lifting assemblies, the lifting work can be stably achieved.

[0016] According to the above technical solution, the lifting assembly includes:

[0017] A hydraulic cylinder 1, the lower surface of which is fixedly mounted on the upper surface of the mounting rod, and a connecting rod is fixedly mounted on one end of the hydraulic cylinder 1;

[0018] A second T-block is fixedly mounted on the end of the connecting rod, and the second T-block is slidably arranged with the guide rail groove of the second guide rail plate;

[0019] The bottom of the second inner wall of the guide rail plate has a rectangular opening and a rectangular groove, and the rectangular opening and the rectangular groove are connected;

[0020] One end of the movable connecting rod is movably connected to the T-block through a pin, and the other end of the movable connecting rod is movably connected to a connecting block through a pin, and the connecting block is fixedly installed on the bottom surface of the pressure plate.

[0021] According to the above technical solution, the lifting assembly also includes a connecting rod, which is fixedly installed on the end face of the pressure plate, and T-blocks are fixedly installed on both ends of the connecting rod. The T-block and the guide groove of the guide plate are slidably arranged. Through the coordinated arrangement of the T-block and the guide plate, the lifting stability of the lifting assembly can be enhanced, making the lifting smoother and more stable.

[0022] According to the above technical solution, the auxiliary component includes:

[0023] The mounting column has two ends fixedly mounted on the inner wall of the rectangular groove;

[0024] The support block is obliquely sleeved on the outer wall of the mounting column, the outer wall of the mounting column is sleeved with a small spring, one end of the small spring is fixedly mounted on the inner wall of the rectangular groove, and the other end of the small spring is fixedly mounted on the surface of the support block;

[0025] The U-shaped rod is fixedly installed with the bottom surface of the support block away from the mounting column.

[0026] According to the above technical solution, the size of the support block is slightly smaller than the size of the rectangular opening. Setting the size of the support block smaller than the size of the rectangular opening allows the support block to completely enter the rectangular opening under external force, and then the T-block 2 can work back and forth smoothly.

[0027] According to the above technical solution, the protection component includes:

[0028] The second hydraulic cylinder is arranged above the pressure plate, and a mounting plate is fixedly mounted on the bottom end of the second hydraulic cylinder;

An auxiliary block is fixedly installed on the bottom of one end of the ramp platform. The auxiliary block is located in the L-shaped through port, and the height of the auxiliary block is smaller than the size of the L-shaped through port. The auxiliary block is fixedly sleeved with a shaft, and both ends of the shaft are rotatably arranged in circular grooves formed on the inner wall of the L-shaped through port.

[0030] According to the above technical solution, a fixing plate is fixedly installed on the top of the hydraulic cylinder 2, and the bottoms of the four corners of the fixing plate are respectively fixedly installed on the tops of the four guide plates 1. The installed fixing plate can stably install the hydraulic cylinder 2 to avoid the hydraulic cylinder 2 being in a suspended position and affecting the operation of the hydraulic cylinder 2.

[0031] According to the above technical solution, a protective plate is fixedly mounted on the outer wall of the shaft, and the length of the protective plate is less than half the length of the inner wall of the L-shaped opening, so that the protective plate can smoothly enter the L-shaped opening and effectively protect the chassis.

[0032] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0033] 1. The present invention can lift the chassis by means of a lifting assembly, which is convenient for maintenance. Here, two hydraulic cylinders are arranged horizontally, and a movable connecting rod is installed through a connecting block and a pressure plate to replace the traditional hydraulic cylinder arranged longitudinally, thereby reducing damage.

[0034] 2. The present invention uses an inclined support block and a small spring to enable the support block to press and support the T-block 2 after it moves to the destination point, thereby further reducing the bearing pressure of the movable connecting rod and the hydraulic cylinder 1, and achieving an effective protection for the hydraulic cylinder.

[0035] 3. The present invention can make the mounting plate drive the steel wire rope to move by means of the second hydraulic cylinder, and finally realize the rotation of the ramp platform by means of the connecting column and the auxiliary shaft, until the ramp platform is perpendicular to the pressure plate, and the protective plate also rotates at the same time, and finally forms a guardrail layout, which blocks the two ends of the chassis and plays a protective role.

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] Example 1: Please refer to Figure 1-9 The present invention provides a technical solution: a vehicle chassis lifting device, characterized in that it includes:

[0049] There are four guide rail plates 1, which are arranged longitudinally. A mounting seat 2 is fixedly installed at the bottom of the guide rail plate 1. The mounting seat 2 is fixedly installed with the bottom surface by bolts. The entire device can be stably installed on the bottom surface through the arrangement of the mounting seat 2, so that the stable lifting work of the device can be ensured to avoid causing danger.

[0050] Among them, a mounting rod 3 is fixedly installed between the guide rail plates 1 arranged at the front and rear positions, and a guide rail plate 2 4 is fixedly installed between the mounting rods 3;

[0051] The pressure plate 7 is arranged above the guide plate 2 4. The pressure plate 7 is connected to the guide plate 2 4 through a lifting assembly 5. There are two lifting assemblies 5. The two lifting assemblies 5 are symmetrically distributed on the left and right sides with the midline of the front side of the guide plate 2 4 as the symmetry axis. The lifting work can be stably realized by the opposing arrangement of the two lifting assemblies 5.

[0052] The top surface of the pressure plate 7 is provided with an L-shaped opening 11;

[0053] An auxiliary component 6 is installed in the guide rail plate 4;

[0054] The pressure plate 7 is connected with a protection component 8 .

[0055] The lifting assembly 5 comprises:

[0056] The lower surface of the hydraulic cylinder 51 is fixedly mounted on the upper surface of the mounting rod 3, and a connecting rod 52 is fixedly mounted on one end of the hydraulic cylinder 51;

[0057] A second T-block 54 is fixedly mounted on the end of the connecting rod 52, and the second T-block 54 is slidably arranged on the guide groove of the second guide plate 4;

[0058] The bottom of the inner wall of the guide rail plate 2 4 has a rectangular opening 13 and a rectangular groove 14, and the rectangular opening 13 and the rectangular groove 14 are connected;

[0059] One end of the movable connecting rod 55 is movably connected to the T-shaped block 54 through a pin, and the other end of the movable connecting rod 55 is movably connected to a connecting block 56 through a pin. The connecting block 56 is fixedly installed on the bottom surface of the pressure plate 7.

[0060] In the specific implementation process, by activating the two horizontally arranged hydraulic cylinders 1 51, the connecting rod 53 can be driven to drive the T-block 2 54 to move smoothly in the guide plate 2 4. Since the movable connecting rod 55 is cleverly installed in the system, and the connecting rod is connected to the pressure plate 7 through the connecting block 56, the pressure plate 7 can be gradually and effectively lifted during the movement of the T-block 2 54 to achieve the lifting function. In this design, the horizontal arrangement of the hydraulic cylinder 1 51 and the use of the T-block 2 54 and the movable connecting rod 55 to replace the traditional longitudinal hydraulic cylinder not only optimize the structural layout, but also significantly reduce the potential risk of damage.

[0061] In this embodiment, the lifting assembly 5 also includes a connecting rod 57, which is fixedly installed on the end surface of the pressure plate 7, and T-blocks 53 are fixedly installed on both ends of the connecting rod 57. The T-block 53 is slidably arranged in the guide groove of the guide plate 1. Through the coordinated arrangement of the T-block 53 and the guide plate 1, the lifting stability of the lifting assembly 5 can be enhanced, making the lifting smoother and more stable.

[0062] Example 2: Based on the above embodiment, the auxiliary component 6 includes:

[0063] The mounting column 62 has two ends fixedly mounted to the inner wall of the rectangular groove 14;

[0064] The support block 61 is obliquely sleeved on the outer wall of the mounting column 62. The outer wall of the mounting column 62 is sleeved with a small spring 63. One end of the small spring 63 is fixedly mounted on the inner wall of the rectangular groove 14, and the other end of the small spring 63 is fixedly mounted on the surface of the support block 61.

[0065] The U-shaped rod 64 is fixedly installed on the bottom surface of the support block 61 away from the mounting column 62. The U-shaped rod 64 can move the support block 61 downward into the rectangular opening 13 to facilitate the reciprocating movement of the T-shaped slider 54 and to facilitate the device to return to a height position.

[0066] In the specific implementation process, in the moving track of the T-shaped slider 2 54, it will squeeze the support block 61 in time, causing the support block 61 to slide smoothly into the rectangular opening 13. This process continues until the T-shaped block 2 54 is completely moved to the other side of the support block 61, and then the moving action is paused. At this time, thanks to the elastic force of the small spring 63, the support block 61 can automatically reset to its initial position. This reset action not only realizes the effective support and slight squeezing of the T-shaped block 2 54, but also further reduces the load borne by the movable connecting rod 55 and the hydraulic cylinder 1 51, thereby effectively extending the service life of the hydraulic cylinder 1 51 and improving its working stability.

[0067] In this embodiment, the size of the support block 61 is slightly smaller than the size of the rectangular opening 13. Setting the size of the support block 61 smaller than the size of the rectangular opening 13 allows the support block 61 to completely enter the rectangular opening 13 under external force, and then the T-block 2 54 can work back and forth smoothly.

[0068] Example 3: Based on the above embodiment, the protection component 8 includes:

[0069] The second hydraulic cylinder 81 is arranged above the pressure plate 7, and a mounting plate 82 is fixedly mounted on the bottom end of the second hydraulic cylinder 81;

[0070] One end of the wire rope 83 is fixedly installed on the bottom surface of the mounting plate 82, and the other end of the wire rope 83 is fixedly installed on the ramp platform 10 through the connecting column 84. Here, the ramp platform 10 can be used to make the vehicle chassis smoothly enter the pressure plate 7, which is convenient for inspection and maintenance. An auxiliary block 85 is fixedly installed on the bottom of one end of the ramp platform 10. The auxiliary block 85 is located in the port of the L-shaped through hole 11, and the height of the auxiliary block 85 is smaller than the size of the port of the L-shaped through hole 11. The auxiliary block 85 is fixedly sleeved with a shaft 86, and the two ends of the shaft 86 are rotatably set with the circular grooves opened on the inner wall of the L-shaped through hole 11.

[0071] In the specific implementation process, after the hydraulic cylinder 81 is started, its power drives the mounting plate 82 to pull and move the steel wire rope 83. Since the steel wire rope 83 is firmly connected to the ramp platform 10 through the connecting column 84, and the ramp platform 10 is connected to the shaft 86 with the help of the auxiliary block 85, this series of mechanical linkages eventually causes the ramp platform 10 to rotate. As the rotation continues, the ramp platform 10 gradually adjusts to a vertical state with the pressure plate 7. In this state, the ramp platform 10 can effectively serve as a blocking structure at both ends of the chassis, providing necessary protection and protection.

[0072] In this embodiment, a fixing plate 9 is fixedly installed on the top of the hydraulic cylinder 81, and the bottoms of the four corners of the fixing plate 9 are respectively fixedly installed on the tops of the four guide plates 1. The installed fixing plate 9 can stably install the hydraulic cylinder 81 to prevent the hydraulic cylinder 81 from being in a suspended position and affecting the operation of the hydraulic cylinder 81.

[0073] Furthermore, a protective plate 12 is fixedly mounted on the outer wall of the shaft 86, and the length of the protective plate 12 is less than half the length of the inner wall of the L-shaped opening 11. In this way, the protective plate 12 can smoothly enter the L-shaped opening 11 when the shaft 86 rotates, thereby effectively protecting the chassis.

[0074] Working principle: First, the vehicle chassis is smoothly transported to the pressure plate 7 through the ramp 10. After the vehicle chassis is stable, the hydraulic cylinder 1 51 is started to drive the connecting rod 52 to move. As the connecting rod 52 moves, the T-type slider 2 54 installed therewith also slides. Due to the ingenious design of the sliding arrangement of the connecting rod 57 and the T-type slider 1 53, especially the T-type slider 1 53 and the guide plate 1 1, the movement of the T-type slider 2 54 can smoothly drive the movable connecting rod 55 to press upward against the pressure plate 7, thereby smoothly lifting the vehicle chassis. During the movement of the T-type slider 2 54, it will gradually squeeze the support block 61. Thanks to the reasonable layout of the support block 61 and the mounting column 62, the support block 61 can smoothly enter the rectangular opening 13. When the T-type slider 2 54 moves to contact one side of the support block 61, the hydraulic cylinder 1 51 is closed, and the lifting work is completed. At this time, the support block 61 just presses against one side of the T-shaped slider 2 54, effectively sharing the force of the movable connecting rod 55 and the hydraulic cylinder 1 51, reducing the potential risk of damage. After the lifting work is completed, the hydraulic cylinder 2 81 is started to drive the mounting plate 82 to move upward. Since the wire rope 83 is connected to the ramp platform 10 through the connecting column 84, and with the help of the auxiliary block 85 and the shaft 86, the upward movement of the mounting plate 82 can drive the ramp platform 10 to rotate until it is vertical to the pressure plate 7. At the same time, the protective plate 12 connected to the shaft 86 also shows a trend of rotation, and part of the area gradually rotates into the L-shaped opening 11. Finally, the four ramp platforms 10 and the two protective plates 12 together form a stable guardrail layout, which effectively blocks and protects the vehicle chassis, avoids the displacement of the vehicle chassis during the lifting process, and ensures the safety of the entire operation process.
