[0024] Embodiment 1:
[0025] Referring to Figures 1 - 4 , a safety protection device for vehicle chassis inspection includes a pit 1, in which a step 101 is fixedly connected. It further includes: two groups of support plates that are liftably arranged on the pit 1. Among them, a fixing plate 8 is fixedly connected to one group of support plates, a clamping plate 10 is rotatably connected to the fixing plate 8, and the clamping plate 10 is detachably connected to the other group of support plates; a movable plate 12 that is slidably connected to the fixing plate 8 and the clamping plate 10. Among them, a protective net 13 is fixedly connected to the movable plate 12, and the protective net 13 is staggered below the support plates; a locking assembly for limiting the clamping plate 10.
[0026] It should be noted that the above two groups of support plates include a left support plate 5 and a right support plate 6. A placement groove 2 is formed in the pit 1, a hydraulic cylinder 3 is fixedly connected in the placement groove 2, the output end of the hydraulic cylinder 3 is fixedly connected with a connecting shaft 4, and the support plate is fixedly connected to the connecting shaft 4.
[0027] Here, the fixing plate 8 is fixedly installed on the left support plate 5, and connecting rods are fixedly connected to both the fixing plate 8 and the clamping plate 10. Connecting plates 9 are rotatably connected to both groups of connecting rods, and the two groups of connecting plates 9 are rotatably connected through a connecting seat. The clamping plate 10 can be folded through the connecting plate 9. When in use, the clamping plate 10 can be stretched from the position of the fixing plate 8 towards the outside. At this time, the two groups of connecting plates 9 are stretched, so that the clamping plate 10 moves to the outside. When not in use, the clamping plate 10 can be folded and moved from the outside to the position of the fixing plate 8 to form a folded style.
[0028] When an operator needs to inspect the chassis of a vehicle, the wheels on both sides of the vehicle can be moved onto the left support plate 5 and the right support plate 6 respectively, and the hydraulic cylinder 3 can drive the left support plate 5 and the right support plate 6 to move upward through the connecting shaft 4, so that the left support plate 5 and the right support plate 6 drive the vehicle to move upward. Subsequently, the operator can move into the pit 1 through the step 101.
[0029] At this time, the operator in the pit 1 needs to fold and stretch the clamping plate 10 on the fixing plate 8, stretch and move the clamping plate 10 from the position of the left support plate 5 to the right support plate 6, and limit the clamping plate 10 through the locking assembly.
[0030] Moreover, sliding grooves 11 are respectively formed in the fixing plate 8 and the clamping plate 10, and both ends of the movable plate 12 are slidably connected in the sliding grooves 11. By sliding the movable plate 12, the stagger - arranged protective nets 13 can be moved above the operator's head. And the operator can directly repair or maintain the vehicle chassis through the mesh holes of the protective nets 13. When encountering danger, such as sharp parts or high - temperature parts falling into the pit 1, the protective nets 13 will intercept the sharp parts or high - temperature parts, preventing the operator from being accidentally scalded or injured, ensuring safety during work. And by sliding the movable plate 12, the position of the protective net 13 can be moved as needed, enabling the operator to repair or maintain different positions of the vehicle chassis, improving the practicability of the device.
[0031] Furthermore, the above - mentioned locking assembly includes a locking bolt 15. A limiting seat 14 is fixedly connected to the bottom of the right support plate 6. The locking bolt 15 is threadedly connected to the limiting seat 14, and the contact end of the locking bolt 15 abuts against the outer wall of the clamping plate 10.
[0032] By tightening the locking bolt 15 clockwise, the locking bolt 15 can be abutted against the outer wall of the clamping plate 10 to limit the position of the clamping plate 10 and prevent the clamping plate 10 from shaking. At the same time, the stability of the movable plate 12 during sliding can be improved.
[0033] In addition, a groove 7 is formed on the side wall of the placement groove 2, and the fixing plate 8 can extend into the groove 7.
[0034] After the vehicle chassis is repaired or maintained, the locking bolt 15 can be rotated counterclockwise, and then the clamping plate 10 can be folded to the position of the fixing plate 8, and the protective net 13 will automatically fold. Subsequently, the hydraulic cylinder 3 is driven to drive the connecting shaft 4 to move downward, so that the left support plate 5 and the right support plate 6 are respectively moved into the placement groove 2. During this process, the clamping plate 10 and the fixing plate 8 will extend into the groove 7 for storage.
[0035] Embodiment 2:
[0036] In order to improve the automation level during vehicle chassis detection, the fixing plate 8 can be set as an electric slide rail, and the movable plate 12 can be a slide rail slider on the electric slide rail. The electric slide rail is usually equipped with a motor, such as a stepper motor or a servo motor. The rotation of the motor is used to drive the movement of the slide rail, and it can also be transmitted to the slide rail through a transmission device, such as a belt, a gear or a lead screw, so that the slide rail slider moves smoothly along a predetermined track. Furthermore, the movable plate 12 drives the protective net 13 to translate on the electric slide rail. The model of the electric slide rail can be the HG series electric guide rail.
[0037] In addition, an infrared radiation detection head can also be provided on the clamping plate 10, and the detection head faces the pit 1. It is usually called a PIR sensor, and its model can be AM312PIR. It is mainly used to detect the infrared radiation of the human body to determine whether there is someone moving in the specified area. When a maintenance worker is detected and scanned by the detection head, the operator's body will radiate infrared rays at a certain temperature, and the PIR sensor can sense this infrared ray signal. The PIR sensor usually consists of two main parts: an infrared receiving element and a signal processing circuit. The receiving element is generally composed of a thermosensitive material and can detect infrared radiation of different wavelengths.
[0038] When an operator passes through the detection area of the sensor, the infrared receiving element of the sensor will sense the temperature change, thereby generating an electrical signal. There is a dual-element structure inside the PIR sensor, which can detect the change of infrared radiation. When the infrared intensity received by one element is different from that of the other element, the sensor will consider that there is an object moving. Subsequently, the sensor transmits the received signal to the internal signal processing circuit. After amplification, filtering, and logical processing, a switching signal is finally output. And a control panel is arranged on the fixing plate 8 for receiving the signal. Furthermore, the control panel can be used to control the motor, so as to start the switch of the motor on the electric slide rail, enabling the movable plate 12 to drive the protective net 13 to translate above the operator, so that it always follows the operator for mobile protection, improving the automation level during the vehicle chassis detection.
[0039] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
