Abstract
Description
Technical Field
[0001] This utility model relates to the field of isolation and protection devices, specifically an isolation and protection device for automobile testing. Background Technology
[0002] Vehicle inspection isolation and protection devices are installed on the inspection platform to prevent vehicles from accidentally rolling backward or slipping off during the inspection process, ensuring inspection safety. After the vehicle drives onto the inspection platform, the motor starts and drives the transmission components to raise the protective plate to the working position. If the vehicle rolls backward, the protective plate is pressed and moves inward to the inspection platform, simultaneously triggering a hydraulic cylinder or spring buffer. At the same time, the slider mechanism guides the pressure to disperse and avoid local overload. When inspecting a vehicle, it needs to be parked on the inspection platform for inspection by professionals. Because there is no isolation and protection device on the inspection platform to prevent the vehicle from rolling backward, the vehicle can easily slip off the inspection platform during the inspection, causing damage to the vehicle or even injury to personnel.
[0003] To address the aforementioned issues, Chinese Patent Publication No. CN218725339U discloses an isolation and protection device for automobile inspection. This device controls the extension of a hydraulic cylinder, which in turn drives a blocking device to rotate around the hinge point between the blocking device and the vertical rod. This causes the blocking plate on the blocking device to extend to the outside of the inspection platform body. Then, a reduction motor is controlled to rotate, driving a screw block to move. The screw block causes the blocking devices to move closer together, blocking and isolating the automobile tires, preventing the automobile from sliding off the inspection platform body during inspection and causing damage to vehicles and personnel.
[0004] While the comparative patent solves the problem of cars easily sliding off the testing platform during inspection, causing damage to the car or even injury to people, the device requires control of hydraulic cylinders and reduction motors, making the operation process more complicated and reducing the practicality of the device.
[0005] Regarding the aforementioned technologies, this device has the drawback of requiring control of both the hydraulic cylinder and the geared motor, which makes the operation process cumbersome and reduces the practicality of the device. Utility Model Content
[0006] Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides an isolation and protection device for automobile inspection. This device only requires the control of a hydraulic cylinder, making the operation process more convenient and improving its practicality. It solves the problem that the operation process is more complicated and reduces the practicality of the device because both hydraulic cylinder and geared motor need to be controlled.
[0007] (II) Technical Solution To achieve the above objectives, this device only requires control of a hydraulic cylinder, making operation more convenient and improving the practicality of the device. This utility model provides the following technical solution: A vehicle inspection isolation and protection device includes a platform body. The platform body has a working groove inside. A limit channel is formed in the top arm of the working groove. A hydraulic cylinder is fixedly connected to the inner bottom wall of the working groove. A lifting rod is provided at the top of the hydraulic cylinder. A lifting plate is fixedly connected to the top of the lifting rod. A through groove is formed at the top of the lifting plate. A limit rod is slidably connected to the inner wall of the through groove. A base block is fixedly connected to the bottom of the limit rod. A spring is fixedly connected to the top of the base block. A groove is formed on the outer wall of the limit rod. A gravity sensor is fixedly connected to the inner wall of the groove.
[0008] As a preferred technical solution of this utility model, the working groove is opened inside the platform body, and the platform body is made of steel structure.
[0009] As a preferred embodiment of this utility model, the bottom of the limiting rod passes through the through groove and extends to the bottom of the lifting plate.
[0010] In a preferred embodiment of this invention, the spring is movably connected to the limiting rod, and the top of the spring is fixedly connected to the bottom of the lifting plate.
[0011] In a preferred embodiment of this utility model, the top of the limiting rod extends into the interior of the limiting channel, and the outer wall of the limiting rod is slidably connected to the inner wall of the limiting channel.
[0012] As a preferred embodiment of this invention, the width of the limiting channel is smaller than the width of the wheel hub.
[0013] (III) Beneficial Effects Compared with the prior art, this utility model provides an isolation and protection device for automobile inspection, which has the following beneficial effects: 1. By activating the hydraulic cylinder, the lifting rod moves the lifting plate upwards. This, in turn, causes multiple lifting plates to move multiple limit rods upwards. When a limit rod is stopped by the wheel hub, it will stop moving upwards. However, limit rods not stopped by the wheel hub will continue to move upwards. Consequently, these limit rods will be positioned on the front and rear sides of the wheel hub, thus limiting the wheel hub and preventing it from moving backwards or forwards automatically. This ensures the safety of the workers. This device only requires controlling the hydraulic cylinder, making the operation convenient and improving its practicality.
[0014] 2. When the limit rod is limited by the car wheel hub, it will no longer move upward. The lifting plate continues to move upward, which will stretch the spring. When the lifting plate moves to its original position, the spring force will drive the limit rod to reset, thus providing an effective auxiliary function for the device, which is worth promoting.

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0018] Example 1 Reference Figure 1-3This is the first embodiment of the present invention, providing an isolation and protection device for vehicle inspection, including a platform body 1. The vehicle to be inspected first drives onto the platform body 1, where workers then conduct professional inspections. The platform body 1 has a working groove 2 inside, and a limiting channel 3 is formed in the top arm of the working groove 2. The limiting channel 3 is narrower than the width of a typical car wheel hub, preventing the wheel hub from falling into the limiting channel 3. A hydraulic cylinder 4 is fixedly connected to the inner bottom wall of the working groove 2. The hydraulic cylinder 4 is an existing device and will not be explained in detail here. A lifting rod 5 is provided at the top of the hydraulic cylinder 4. Activating the hydraulic cylinder 4 will extend the lifting rod 5, causing its top to move upwards. A lifting plate 6 is fixedly connected to the top of the lifting rod 5. A through groove 7 is formed at the top of the lifting plate 6, and a sliding connection is made to the inner wall of the through groove 7. The limit rod 8 has a base block 9 fixedly connected to its bottom, and a spring 10 fixedly connected to the top of the base block 9. The hydraulic cylinder 4 is activated to drive the lifting plate 6 upward via the lifting rod 5. In turn, the multiple lifting plates 6 will drive the multiple limit rods 8 upward. When the limit rod 8 is limited by the car wheel hub, it will stop moving upward. However, the limit rod 8 that is not limited by the wheel hub will continue to move upward. Thus, the limit rod 8 that is not limited by the wheel hub will be located on the front and rear sides of the wheel hub, thereby limiting the wheel hub. The wheel hub will not move backward or forward automatically, thus ensuring the personal safety of the staff. The outer wall of the limit rod 8 has a groove 11, and the inner wall of the groove 11 is fixedly connected to a gravity sensor 12. When the car reverses automatically, it will press on the gravity sensor 12, which will trigger the alarm on the car, allowing the staff to detect the fault in time.
[0019] Specifically, the working slot 2 is located inside the platform body 1. The platform body 1 is made of steel and has the capacity to support a car. The car will not collapse when it is parked on the platform body 1.
[0020] Reference Figure 1-3 The bottom of the limiting rod 8 passes through the through groove 7 and extends to the bottom of the lifting plate 6. The top of the limiting rod 8 will move downward when subjected to force.
[0021] Furthermore, the spring 10 is movably connected to the limiting rod 8, and the top of the spring 10 is fixedly connected to the bottom of the lifting plate 6. When the limiting rod 8 is limited by the car wheel hub, it will no longer move upward. The lifting plate 6 continues to move upward, which will stretch the spring 10. When the lifting plate 6 moves to its original position, the elastic force of the spring 10 will drive the limiting rod 8 to reset.
[0022] Furthermore, the top of the limiting rod 8 extends into the interior of the limiting channel 3, and the outer wall of the limiting rod 8 is slidably connected to the inner wall of the limiting channel 3. The hydraulic cylinder 4 is activated to drive the lifting plate 6 to move upward through the lifting rod 5. In turn, multiple lifting plates 6 will drive multiple limiting rods 8 to move upward. When the limiting rod 8 is limited by the car wheel hub, it will no longer move upward, while the limiting rod 8 that is not limited by the wheel hub will continue to move upward. Thus, the limiting rod 8 that is not limited by the wheel hub will be located on the front and rear sides of the wheel hub, thereby playing a limiting role on the wheel hub.
[0023] Specifically, the width of the limiting channel 3 is smaller than the width of the wheel hub, so the car wheel hub will not fall into the interior of the limiting channel 3 when it is located on the limiting channel 3.
[0024] During use, the car to be inspected first drives onto the platform body 1. Then, the staff conducts a professional inspection of the car. The width of the limiting channel 3 is relatively narrow, smaller than the width of a typical car wheel hub. Therefore, the car wheel hub, positioned on the limiting channel 3, will not fall into its interior. The hydraulic cylinder 4 is activated, which drives the lifting plate 6 upward via the lifting rod 5. This, in turn, causes multiple lifting plates 6 to move multiple limiting rods 8 upward. When the limiting rod 8 is limited by the car wheel hub, it will stop moving upward. However, the limiting rod 8 not limited by the wheel hub will continue to move upward. Consequently, the limiting rod 8 not limited by the wheel hub will be located on the front and rear sides of the wheel hub, thus limiting the wheel hub and preventing it from moving backward or forward automatically, thereby ensuring the safety of the staff.
[0025] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
