[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] Reference Figure 1 and Figure 3 The utility model provides an embodiment: a maintenance lying plate car, including a base 1 and a connecting rod 13, an open groove 3 is opened in the middle of the top of the base 1, and the front side of the base 1 is rotatably connected with a rotating rod 4, the rear end of the rotating rod 4 passes through the open groove 3 and is fixedly connected with an active bevel gear 5, the inside of the open groove 3 is rotatably connected with a two-way screw rod 6, the middle of the outer side of the two-way screw rod 6 is fixedly connected with a driven bevel gear 7, the driven bevel gear 7 is meshed with the active bevel gear 5, the left and right sides of the outer wall of the two-way screw rod 6 are threadedly connected with movable blocks 8, the top of the movable block 8 is rotatably connected with a first rotating shaft 9, a plate body 10 is arranged on the upper side of the base 1, a U-shaped frame 11 is fixedly connected to the middle of the bottom end of the plate body 10, the left and right sides of the inside of the U-shaped frame 11 are rotatably connected with a second rotating shaft 12, the two second rotating shafts 12 are respectively connected to the corresponding first rotating shaft 9 through the connecting rod 13, and the front and rear sides of the plate body 10 are provided with a pick-up and placement mechanism 2;

[0040] Specifically, when the rotating rod 4 is rotated, the active bevel gear 5 on the rotating rod 4 will move accordingly, and at the same time, the driven bevel gear 7 meshing with the active bevel gear 5 will also rotate along with the rotation of the active bevel gear 5. This series of actions constitutes a precise transmission system, in which the bidirectional screw 6 is another important component. When the rotating rod 4 rotates, the movement of the driven bevel gear 7 will be transmitted to the bidirectional screw 6, causing the bidirectional screw 6 to rotate. At this time, the movable block 8 on the bidirectional screw 6 will move toward the middle under the action of force. The movement of the movable block 8 is not meaningless. It drives the rotation of the first rotating shaft 9, and the rotation of the first rotating shaft 9 is transmitted to the second rotating shaft 12 through the connecting rod 13. In this way, the transmission process of the entire device forms a closed cycle, and this closed cycle ultimately realizes the lifting of the plate body 10. The lifting of the plate body 10 means that the staff can easily adjust the height of the plate body 10 to facilitate the maintenance of vehicles with different chassis heights. This undoubtedly greatly improves the work efficiency and meets the needs of users.

[0041] Reference Figure 1 , Figure 2 and Figure 4The pick-and-place mechanism 2 includes a hollow box 201, which is respectively arranged on the front and rear sides of the plate body 10. The inner bottoms of the two hollow boxes 201 are fixedly connected with springs 202. The inner sides of the hollow boxes 201 are slidably connected with a placement frame 203. The tops of the multiple springs 202 are respectively fixedly connected with the left and right sides of the bottoms of the corresponding placement frames 203. A baffle 204 is arranged at the middle and upper part of the inner side of the hollow box 201. One side of the baffle 204 passes through the hollow box 201 and is fixedly connected with a pull rod 205. The two hollow boxes 201 are fixedly connected with a limit block 2 on the far sides thereof. 08, the front and rear sides of the plate body 10 are provided with limit slots 209, the limit blocks 208 are slidably connected with the corresponding limit slots 209, the sizes of the two placement frames 203 are matched with the internal sizes of the corresponding hollow boxes 201, the interiors of the multiple springs 202 are provided with hollow rods 206, the bottom ends of the multiple hollow rods 206 are respectively fixedly connected with the inner bottoms of the corresponding hollow boxes 201, the inner sides of the hollow rods 206 are slidably connected with movable rods 207, and the top ends of the multiple movable rods 207 are respectively fixedly connected with the left and right sides of the bottoms of the corresponding placement frames 203;

[0042] Specifically, the hollow boxes 201 on both sides are moved to the middle position of the plate body 10 through the limit grooves 209. This design makes it more convenient for the staff to take and put tools, saving time and energy. The function of the limit grooves 209 is to ensure that the hollow box 201 can be accurately moved to the middle of the plate body 10 to ensure the stability of the entire device. Then, the baffle 204 can be easily pulled out through the pull rod 205. In this process, the spring 202 will release the previous squeezing force, and this force will drive the placement frame 203 to pop out from the hollow box 201. This design makes it easier to take and put tools without spending extra effort. It is worth mentioning that there are grooves of different shapes on the placement frame 203, which can not only classify the tools, but also avoid the tools from piling up together, thereby avoiding the staff from wasting time when looking for tools. This classification method makes the tools orderly and clear at a glance when taking them, greatly improving work efficiency.

[0043] Reference Figure 3 , the left and right ends of the front and rear sides of the opening slot 3 are provided with slide grooves 15, and the front and rear sides of the two movable blocks 8 are fixedly connected with sliders 14, and the sliders 14 are slidably connected with the corresponding slide grooves 15 respectively;

[0044] Specifically, the sliding groove 15 can limit the moving track of the movable block 8 so that it can move more smoothly.

[0045] Reference Figure 1 and Figure 2The front and rear ends of the right side of the plate body 10 are fixedly connected to a support rod 16, the left end of the support rod 16 is rotatably connected to a reflector 17, the four corners of the bottom of the base 1 are rotatably connected to universal wheels 19, and a headrest 18 is provided on the top right side of the plate body 10;

[0046] Specifically, the reflector 17 can facilitate the staff to view the tools in the placement frame 203, and the universal wheel 19 can facilitate the movement of the device. The headrest 18 can provide a comfortable working environment for the staff, thereby improving the practicality of the device.

[0047] Working principle: When using the device, the staff first lies on the plate body 10, and then the universal wheel 19 can be used to move it to the bottom of the vehicle to be repaired. At this time, the rotating rod 4 can be rotated according to the chassis height of the vehicle to be repaired, and the active bevel gear 5 on the rotating rod 4 will rotate accordingly. The driven bevel gear 7 will also rotate due to the engagement with the active bevel gear 5, thereby driving the bidirectional screw rod 6 to rotate. At this time, the movable block 8 on the bidirectional screw rod 6 will move toward the middle, and the first rotating shaft 9 on the movable block 8 will rotate accordingly, and the second rotating shaft 12 will also rotate through the connecting rod 13. At this time, the plate body 10 can be lifted up, so that the staff can conveniently repair the vehicle that is not repaired. Vehicles with the same chassis height can be inspected and repaired, thereby meeting the needs of users, and after the height of the plate body 10 is adjusted, the hollow boxes 201 on both sides are moved to the middle position of the plate body 10 through the limit grooves 209, which can be convenient for the staff to take and put. The baffle 204 can be pulled out by the pull rod 205. At this time, the spring 202 will release the squeezing force and drive the placement frame 203 to pop out from the hollow box 201. The tools can be classified through the different grooves on the placement frame 203, thereby avoiding the situation where the tools are piled up and inconvenient for the staff to find. At the same time, it is relatively simple to take and put the tools, thereby improving the practicality of the device.

[0048] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
