[0010] In a preferred embodiment of this utility model, the testing platform is threadedly fixedly connected to the testing frame, the testing frame is fixedly connected to the inclined plate, and the inclined block is slidably connected to the inner side of the mounting groove.

[0011] In a preferred embodiment of this utility model, the inclined plate is rotatably connected to the support rod, the support rod is rotatably connected to the compression spring, and the compression spring is rotatably connected to the bottom of the inner side of the protective block.

[0016] Beneficial effects

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This automatic lifting and detection device for truck inspection uses hydraulic cylinders to drive the first and second lifting arms to rise and fall. Two limit seats limit the movement of the first lifting arm. The limit rod and connecting rod can move linearly on the outer wall of the guide rail via a slider, ensuring the stability of the first and second lifting arms. The rounded corner limit plate fixes the connecting rod to one end of the first and second lifting arms, providing support for the connecting rod and facilitating the installation of the damper. The damper can buffer and reduce the downward force applied by the inspection platform. The speed bump helps to limit the movement of the truck. When the truck is pressed to the top, the inclined block extends downward through a compression spring, causing the inclined block to descend into the mounting groove. When the truck drives onto the speed bump, the inclined block rebounds through the compression spring to the rear tire of the truck, limiting its movement. The elastic telescopic rods can also provide support and guidance for the use of the inclined block. Attached Figure Description

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figures 1-5 As shown, an automatic lifting inspection device for truck inspection includes a mobile trolley 1, a base plate 2, and an inspection platform 4. An automatic limit component 5 is installed on the top of the inspection platform 4.

[0027] The automatic limit assembly 5 includes a detection frame 501 set on the top of the detection table 4. Multiple speed bumps 502 are set on the top of the detection frame 501. One end of the detection table 4 and the detection frame 501 is connected to an inclined plate 503. The top of the detection frame 501 near the inclined plate 503 is provided with an installation groove 504. An inclined block 505 is set inside the installation groove 504. A support rod 506 is connected to the bottom of the inclined block 505. A compression spring 507 is connected to the bottom of the support rod 506. A protective block 509 is connected to the bottom of the compression spring 507. A limit plate 508 is connected to the outer wall of the compression spring 507 near the protective block 509. Both ends of the top of the protective block 509 are connected to elastic telescopic rods 510.

[0028] The testing table 4 is threadedly fixed to the testing frame 501, the testing frame 501 is fixedly fixed to the inclined plate 503, and the inclined block 505 is slidably connected to the inner side of the mounting groove 504; the inclined plate 503 is rotatably connected to the support rod 506, the support rod 506 is rotatably connected to the compression spring 507, and the compression spring 507 is rotatably connected to the bottom of the inner side of the protective block 509; the limiting plate 508 is sleeved on the end of the compression spring 507 near the inner side of the protective block 509, the protective block 509 is rotatably connected to the elastic telescopic rod 510, and the elastic telescopic rod 510 is rotatably connected to the bottom of the testing table 4;

[0029] The inspection frame 501 is fixed to the top edge of the inspection platform 4, supporting and accommodating components such as the speed bump 502, the ramp 503, and the ramp block 505. The inspection frame 501 is equipped with the speed bump 502, which is typically made of rubber or other elastic materials and has a certain thickness and height, used to force vehicles to slow down when they pass over it. Ramps 503 are provided on either side or one side of the speed bump 502, providing a smooth transition from the ground to the top surface of the inspection platform 4, facilitating vehicle access. Inside the inspection frame 501, near the speed bump 502, a mounting groove 504 is provided, and the ramp block 505 is housed within the mounting groove 504. The bottom of the ramp block 505 is supported by a compression spring 50. 7. A compression spring 507 is installed in the mounting groove 504, with one end fixed to the bottom of the mounting groove 504 and the other end pressing against the bottom of the inclined block 505. Under normal conditions, i.e., when no vehicle rear wheel is pressing on the speed bump 502, the compression spring 507 pushes the inclined block 505 upward, causing its upper end, i.e., the working end, to extend out of the mounting groove 504 and be in the ready-to-work position. An elastic telescopic rod 510 is also installed in the mounting groove 504, with its two ends connected to the side of the inclined block 505 and the side wall of the mounting groove 504, respectively. The elastic telescopic rod 510 provides a certain supporting force while allowing… The inclined block 505 extends and retracts vertically under the action of the compression spring 507, which guides and stabilizes its movement, preventing it from swaying or tilting during the extension and retraction process. When the rear wheels of the truck run over the speed bump 502, the weight and pressure of the rear wheels are transmitted through the speed bump 502, lifting the upper end of the inclined block 505. The inclined block 505 overcomes the elastic force of the compression spring 507 and moves downward, eventually retracting completely into the mounting groove 504, thus making room for the rear wheels of the truck and allowing the vehicle to continue moving forward onto the testing platform 4. When the front wheels of the truck... When the vehicle passes over speed bump 502 and the rear wheels are about to pass over speed bump 502, the rear wheels leave the support of speed bump 502, and the inclined block 505 loses downward pressure. At this time, the elastic force of the compression spring 507 drives the inclined block 505 to rebound upward, so that its upper end quickly pops out of the mounting groove 504 and accurately presses against the tire tread of the truck's rear wheel. The elastic telescopic rod 510 ensures that the inclined block 505 remains stable after rebounding into place and effectively limits the truck's rear wheel to the designated position on the test platform 4, preventing the vehicle from moving back and forth during the test and ensuring the accuracy of the test data.

[0030] A lifting adjustment assembly 3 is provided on the top of the base plate 2. The lifting adjustment assembly 3 includes limiting seats 301 at both ends of the top of the base plate 2. The inner sides of the two limiting seats 301 are connected to a first lifting arm 302 via limiting wheels. One end of the first lifting arm 302 is connected to a second lifting arm 303. A reinforcing plate 304 is connected between the contact points of the first lifting arm 302 and the second lifting arm 303. A limiting rod 305 is connected to the end of the two second lifting arms 303 away from the first lifting arm 302. The limiting rod 305 is away from the second lifting arm 302. One end of the lowering arm 303 is connected to a slider 306, and one end of the slider 306 is connected to a guide rail 307. The ends of the first lifting arm 302 and the second lifting arm 303 away from the limit seat 301 and the limit rod 305 are both connected to rounded corner limit plates 309. The side of the rounded corner limit plate 309 close to the detection table 4 is connected to a connecting rod 310. The top of the rounded corner limit plate 309 is connected to a support plate 311. The top of the support plate 311 is connected to a damper 312. One end of the top of the mobile trolley 1 is connected to a hydraulic cylinder 308.

[0031] The first lifting arm 302 and the second lifting arm 303 are rotatably connected to the limiting seat 301 and the limiting rod 305 respectively via limiting wheels. The limiting rod 305 and the connecting rod 310 are rotatably connected to the slider 306, which is slidably connected to the outer wall of the guide rail 307. The reinforcing plate 304 is threadedly fixed to the first lifting arm 302 and the second lifting arm 303. The first lifting arm 302 and the second lifting arm 303 are threadedly fixed to the rounded corner limiting plate 309. The four rounded corner limiting plates 309 are fixedly connected to the support plate 311. The support plate 311 is rotatably connected to the damper 312, and the top of the damper 312 is rotatably connected to the bottom of the detection table 4.

[0032] The lifting adjustment assembly 3 is mounted on the base plate 2 and is used to drive the testing platform 4 to lift. The lifting adjustment assembly 3 mainly includes two symmetrically arranged first lifting arms 302, two symmetrically arranged second lifting arms 303, two limit seats 301, a hydraulic cylinder 308, and related auxiliary structures. Specifically, the two limit seats 301 are respectively fixedly mounted on the upper surface of the base plate 2. Guide rails are installed on the limit seats 301 to guide and limit the lifting movement of the first lifting arms 302, ensuring that their movement trajectory is stable, so that the first lifting arms 302 and the second lifting arms 303 can move up and down. The two lifting arms 303 can rotate around the limiting seat 301 to achieve lifting. Between the first lifting arm 302 and the second lifting arm 303, the reinforcing plate 304 can increase the connection strength and overall rigidity between the two arms, preventing deformation or shaking during lifting. The bottom of the testing platform 4, which is in contact with the lifting adjustment assembly 3, is provided with four rounded corner limiting plates 309, located at the four corners or other key support points. The rounded corner limiting plates 309 are provided to securely fix the connecting rod 310 to the bottom of the testing platform 4. One end of the connecting rod 310 is connected by a screw. A bolt is fixed to one end of the rounded corner limiting plate 309 near the testing platform 4, while the other end of the connecting rod 310 is rotatably connected to the slider 306. This ensures that the connecting rod 310 and the slider 306 can move in tandem when the testing platform 4 is raised or lowered, maintaining the guiding effect of the guide rail 307 on the raising and lowering motion. A support plate 311 is fixedly installed on the top of the rounded corner limiting plate 309. The top of the support plate 311 is connected to the bottom of the damper 312, and the top of the damper 312 is also connected to the bottom of the testing platform 4 via a pin or other rotatable connection structure, forming a closed-loop support and damping structure. When the testing platform 4 carries a truck, especially when the truck drives onto or off the testing platform 4, a large impact and vibration will be generated. The weight of the testing platform 4 and the weight of the truck will be transmitted to the damper 312 through the connecting rod 310, the rounded corner limit plate 309, and the support plate 311. The damper 312, such as a hydraulic or pneumatic damper, can absorb and dissipate this impact energy, and play a buffering and shock-absorbing role against the downward gravity and dynamic impact of the testing platform 4, effectively preventing the testing platform 4 from shaking violently, improving the stability and accuracy of the test, and protecting the testing platform 4 and related structures from damage.

[0033] It should be noted that this utility model is an automatic lifting and detection device for truck inspection. In use, the entire device is placed on a mobile trolley 1, with the detection platform 4 located on the base plate 2 and supported by the lifting adjustment assembly 3. The automatic limit assembly 5 is installed on top of the detection platform 4. At this time, the lifting adjustment assembly 3 is at its initial height, and the detection platform 4 is in a lower position. The speed bump 502 on the detection frame 501 and the inclined plates 503 on both sides are exposed, guiding the vehicle to enter. The truck first passes over the inclined plates 503, which provide a smooth transition, facilitating the vehicle's entry onto the detection platform 4. Subsequently, the truck's front and rear wheels sequentially press onto the speed bump 502. The undulating design of the speed bump 502 forces the vehicle to slow down, providing a safe buffer for subsequent precise stopping and limiting. When the truck's rear wheels... When the speed bump 502 is pressed against one end of the inclined block 505, the inclined block 505 is subjected to downward pressure. This pressure compresses the compression spring 507 via the support rod 506 at its bottom. The compressed spring 507 causes the inclined block 505 to slide along the inner side of the mounting groove 504, moving downwards to temporarily avoid direct impact on the vehicle's tires, preventing damage or operational errors. Following the prompting of the speed bump 502, the driver stops the vehicle at the intended position on the testing platform 4. At this point, the rear wheels should be approximately above the inclined block 505, and the front wheels should be at the other end of the testing platform 4. The pressure on the inclined block 505 decreases, and the compression spring 507 generates an upward restoring force, pushing the inclined block 505 back. The inclined block 505 slides up along the inner side of the mounting groove 504 until its inclined surface contacts the rear tire of the truck. The elastic telescopic rod 510 plays a supporting and guiding role in the rebound of the inclined block 505 and subsequent limiting work, ensuring that the inclined block 505 stably holds the tire and prevents the vehicle from moving back and forth during the inspection process. The limiting plate 508 and the protective block 509 protect the compression spring 507 and limit its stroke to prevent overshoot.

[0034] The hydraulic cylinder 308 on top of the mobile trolley 1 is activated, and the hydraulic cylinder 308 begins to extend. The extension force of the hydraulic cylinder 308 acts directly on the lifting adjustment assembly 3, driving the first lifting arm 302 and the second lifting arm 303 to move upward synchronously. The two limit seats 301 limit and guide the root of the first lifting arm 302 to prevent unnecessary swaying. As the lifting arm rises, the limit rods 305 at the ends of the two second lifting arms 303 slide linearly on the outer wall of the guide rail 307 via the sliders 306 at their ends. The guide rail 307 provides precise guidance for the movement of the limit rods 305, greatly enhancing the stability of the entire lifting system and preventing shaking. One end of the connecting rod 310 is fixed to the first and second lifting arms by the rounded corner limit plate 309. At the end of arm 303, the other end provides support. The design of rounded corner limit plate 309 not only fixes the connecting rod 310, but also facilitates the installation position of damper 312. As the testing platform 4 rises with the lifting arm, its weight and the weight of the truck it carries are transferred to damper 312 through support plate 311. Damper 312 starts to work, absorbing and buffering the downward impact force generated by the testing platform 4 during the rising process and when it reaches the highest point, making the lifting process more stable, reducing vibration and noise, and protecting the testing platform and lifting mechanism. The lifting arm continues to move until the testing platform 4 rises to the preset testing height. At this time, the buffering effect of damper 312 is more obvious, ensuring that the testing platform 4 stays stably at this height, providing a stable platform for subsequent weighing, testing and other operations.
