[0023] The following will be combined with the drawings of the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0024] Reference Figure 1 and Figure 2 The utility model provides an embodiment of a three-dimensional parking garage chain transmission device with an overload protection function, comprising a support frame 1, the outer walls of both sides of the support frame 1 are fixedly connected to a fixed frame 2, the outer wall of the fixed frame 2 is fixedly connected to a motor 1 3, the output end of the motor 1 3 is fixedly provided with a connecting column 4, the outer wall of the connecting column 4 is rotatably connected to the interior of the fixed frame 2 and the support frame 1, the outer wall of the connecting column 4 is fixedly connected to a sprocket 5, the tooth end of the sprocket 5 is meshingly connected to a chain body 6, the outer wall of the fixed frame 2 is fixedly connected to a motor 2 7, the output end of the motor 2 7 is fixedly provided with a forward and reverse screw rod 8, the outer wall of the forward and reverse screw rod 8 is threadedly connected to a clamping block 9, the inner wall of the clamping block 9 is slidably connected to a slide rail 10, the lower surface of the slide rail 10 is fixedly connected to the inner wall of the fixed frame 2, the outer wall of the chain body 6 is provided with a support assembly, and the support assembly is used to support the car;

[0025] When the motor 1 is turned on, the motor 1 drives the connecting column 4 to rotate inside the supporting frame 1 and the fixing frame 2. The supporting frame 1 and the fixing frame 2 can support the connecting column 4 to ensure the stable rotation of the connecting column 4. The rotation of the connecting column 4 will drive the sprocket 5 to rotate, and the rotation of the sprocket 5 will also drive the chain body 6 to slide. At the same time, the fixing frame 2 can also support the motor 2 7. When the motor 2 7 is turned on, the motor 2 7 will drive the forward and reverse screw rods 8 to rotate, and the rotation of the forward and reverse screw rods 8 will drive the clamping block 9 to slide on the outer wall of the slide rail 10. The slide rail 10 can support the clamping block 9 to ensure the stability of the clamping block 9 when sliding, and the fixing frame 2 can support the slide rail 10. When the clamping blocks 9 on both sides slide synchronously in opposite directions, they can clamp the connecting column 4, so that they clamp and fix the connecting column 4 to prevent the connecting column 4 from rotating.

[0026] Reference Figure 2 The support assembly includes a support plate 11, the outer wall of the support plate 11 is fixedly connected to the outer wall of the chain body 6, the inner part of the support plate 11 is rotatably connected to a rotating column 12, the outer wall of the rotating column 12 is fixedly connected to a parking frame 13, and the outer wall of the parking frame 13 is provided with a weighing sensor 14;

[0027] Specifically, the chain body 6 can play the role of fixed support for the support plate 11, and the support plate 11 can also play the role of support for the rotating column 12, and the rotating column 12 can play the role of fixed support for the parking frame 13. The parking frame 13 is equipped with a weighing sensor 14, which can measure the weight of the vehicle on the upper surface of the parking frame 13. When the weight measured by the weighing sensor 14 is too heavy, the weighing sensor 14 will close the fixed frame 2 and turn on the motor 2 7 at the same time to prevent the sprocket 5 from rotating under overload, causing serious wear or even breakage of the sprocket 5 and the chain body 6.

[0028] Reference Figure 3 and Figure 4 , the outer wall of the support frame 1 is fixedly connected to a fixing plate 15, and the upper surface of the fixing plate 15 is fixedly connected to a water pump 16; the input end of the water pump 16 is fixedly connected to a material barrel 17, and the outer wall of the material barrel 17 is fixedly connected to the outer wall of the support frame 1; the output end of the water pump 16 is fixedly connected to a pipe 18, and the outer wall of the pipe 18 is fixedly connected to the inside of the support frame 1; the outer wall of the pipe 18 is fixedly connected to a frame 19, and the outer wall of the frame 19 is fixedly connected to a motor three 20; the output end of the motor three 20 is fixedly provided with a worm 21, and the tooth end of the worm 21 is meshed with a worm wheel 22; the inside of the worm wheel 22 is fixedly connected to a sleeve 23, the outer wall of the sleeve 23 is rotatably connected to the inner wall of the frame 19, and the inner wall of the sleeve 23 is rotatably connected to the outer wall of the pipe 18;

[0029] Specifically, the support frame 1 can play a role of fixed support for the fixed plate 15, and the fixed plate 15 can play a role of fixed support for the water pump 16. When the water pump 16 is turned on, the water pump 16 will transport the lubricating fluid inside the barrel 17 to the inside of the pipe 18. The support frame 1 can play a role of fixed support for the frame 19, and the frame 19 can play a role of fixed support for the motor three 20. When the motor three 20 is turned on, the motor three 20 will drive the worm 21 to rotate, and the rotation of the worm 21 will drive the worm wheel 22 to rotate, and the rotation of the worm wheel 22 will also drive the sleeve 23 to rotate on the outer wall of the pipe 18. The sleeve 23 and the pipe 18 are both provided with grooves. By adjusting the positions of the two grooves, the opening size can be adjusted to achieve the effect of adjusting the supply amount of lubricating fluid. Lubrication can effectively reduce the friction between the chain body 6 and the sprocket 5, reduce wear, and extend the service life of the transmission system. By adjusting the supply amount of lubricating fluid according to parameters such as the load and speed of the system, the effect of adapting to different workloads can be achieved.

[0030] Working principle: When the device needs to be used, the worker can first turn on the water pump 16 to allow the water pump 16 to transport the lubricating fluid inside the barrel 17 to the inside of the pipe 18, and then turn on the motor 3 20, and the motor 3 20 drives the worm 21 to rotate, and the rotation of the worm 21 will drive the worm wheel 22 to rotate, and the rotation of the worm wheel 22 will also drive the sleeve 23 to rotate. The opening size of the pipe 18 is adjusted by the rotation of the sleeve 23 to adjust the supply of lubricating fluid. When the weighing sensor 14 detects that the weight of the garage reaches an overload, the weighing sensor 14 can close the fixed frame 2, so that the fixed frame 2 cannot drive the sprocket 5 to rotate through the connecting column 4, and thus cannot drive the chain body 6 to slide, and then The rear weighing sensor 14 can turn on the motor 2 7, and the motor 2 7 drives the forward and reverse screw rods 8 to rotate, and the rotation of the forward and reverse screw rods 8 will drive the clamping block 9 to slide. When the clamping block 9 slides synchronously in opposite directions, the connecting column 4 can be clamped and fixed, thereby preventing the sprocket 5 from rotating, and preventing the sprocket 5 from continuing to rotate due to inertia or excessive load. That is, the device can not only reduce the wear of the sprocket 5 and the chain body 6 by quantitatively supplying lubricating fluid, extend the service life of the transmission system, and adapt to different workloads, but also adjust the rotation of the sprocket 5 when the garage is overweight, to prevent the sprocket 5 and the chain body 6 from serious wear or even breakage, reduce the risk of damage, and improve safety.

[0031] 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 replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
