DETAILED DESCRIPTION
[0016] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments.

[0018] See also Figure 1-4 , the present invention provides an embodiment: an automatic lifting and centering device for a lifting platform, including a frame assembly 1, a lifting vehicle 2 is slidably installed on the inner side of the frame assembly 1, a protective cover 3 is fixedly connected to the front end of the frame assembly 1, a motor 4 is fixedly connected to the upper end of the frame assembly 1, a transmission assembly 5 is installed at the front end of the motor 4, a support seat 6 is movably connected to the outer side of the transmission assembly 5, a gear piece 7 is movably connected to the inner side of the protective cover 3, a transmission chain 8 is meshingly connected to the outer side of the gear piece 7, a chain tensioner 9 is installed at the lower end of the transmission chain 8, a contact pad 10 is fixedly connected to the upper end of the lifting vehicle 2, and a sliding wheel 11 is installed on the side of the upper end of the lifting vehicle 2 close to the contact pad 10.
[0019] The protective cover 3 is U-shaped, and the transmission assembly 5 extends to the inside of the gear plate 7. The transmission assembly 5 is fixedly connected to the gear plate 7. There are two groups of gear plates 7. The other group of gear plates 7 is installed at one end of the frame assembly 1 near the lower side. The transmission chains 8 form a meshing transmission connection with the two groups of gear plates 7. The rear end of the chain tensioner 9 is installed at the front end of the lifting vehicle 2.
[0020] When in use, start the motor 4, so that the motor 4 drives the transmission component 5 to rotate inside the support base 6, and the transmission component 5 drives the gear piece 7 to rotate, so that the gear piece 7 drives the transmission chain 8 to move, and the transmission chain 8 drives the lifting vehicle 2 to move upward inside the frame component 1 through the chain tensioner 9, so as to lift the plate upward, and make the gear piece 7 and the transmission chain 8 operate inside the protective cover 3, so that the protective cover 3 isolates the gear piece 7 and the transmission chain 8 inside it, so that the protective cover 3 can prevent workers from accidentally touching the gear piece 7 and the transmission chain 8, so that the protective cover 3 has a protective effect on the workers. If it is used for a long time, it will cause the transmission chain 8 to be stretched. When the force becomes larger, first twist the chain tensioner 9, so that the chain tensioner 9 tightens the transmission chain 8 inward, thereby adjusting the overall tension of the transmission chain 8, so that the transmission chain 8 can better form a meshing transmission connection with the two sets of gear plates 7, and by starting the motor 4, the motor 4 drives the transmission assembly 5 to rotate on the inner side of the support base 6, and then the gear plate 7 drives the transmission chain 8 to move, which can facilitate the transmission chain 8 to drive the lifting vehicle 2 to move upward on the inner side of the frame assembly 1. By twisting the chain tensioner 9, the chain tensioner 9 tightens the transmission chain 8 inward, thereby adjusting the overall tension of the transmission chain 8, which can greatly improve the service life of the lifting vehicle 2.
[0021] A sliding rail 12 is fixedly connected to the inner side of the lifting vehicle 2, and a sliding seat 13 is slidably connected to the outer side of the sliding rail 12. One end of the sliding seat 13 is fixedly connected to a hydraulic cylinder 14, and a pushing block 15 is installed on the upper telescopic end of the hydraulic cylinder 14. There are multiple groups of contact pads 10 and several groups of sliding wheels 11. The sliding seat 13 and the pushing block 15 are both located on the inner side of the lifting vehicle 2, and the upper end of the pushing block 15 is flush with the upper end of the lifting vehicle 2.
[0022] At this time, the worker puts the plate on the lifting vehicle 2 and places the plate on the pushing block 15, then starts the hydraulic cylinder 14, so that the hydraulic cylinder 14 pushes the pushing block 15 to move upward, and then starts the sliding seat 13, so that the sliding seat 13 slides along the sliding rail 12, so that the pushing block 15 drives the plate to move, so that the plate moves to the center of the lifting vehicle 2, so that the plate can be centered.
[0023] Working principle: During use, the worker first places the plate on the lifting vehicle 2 and places the plate on the pushing block 15, then starts the hydraulic cylinder 14, so that the hydraulic cylinder 14 pushes the pushing block 15 to move upward, and then starts the sliding seat 13, so that the sliding seat 13 slides along the sliding rail 12, so that the pushing block 15 drives the plate to move, so that the plate moves to the center of the lifting vehicle 2, so that the plate is centered, and then starts the motor 4, so that the motor 4 drives the transmission component 5 to rotate in the inner side of the support seat 6, and the transmission component 5 drives the gear piece 7 to rotate, so that the gear piece 7 drives the transmission chain 8 to move, and the transmission chain 8 drives the lifting vehicle 2 to move upward in the inner side of the frame assembly 1 through the chain tensioner 9, so as to lift the plate upward, and make the gear piece 7 and the transmission chain 8 operate in the inner side of the protective cover 3, so that the protective cover 3 isolates the gear piece 7 and the transmission chain 8 in its inner side. The protective cover 3 can prevent workers from accidentally touching the gear plate 7 and the transmission chain 8, so that the protective cover 3 has a protective effect on the workers. If the tension of the transmission chain 8 increases due to long-term use, the chain tensioner 9 is first twisted to tighten the transmission chain 8 inward, thereby adjusting the overall tension of the transmission chain 8, so that the transmission chain 8 can better form a meshing transmission connection with the two sets of gear plates 7. By starting the motor 4, the motor 4 drives the transmission assembly 5 to rotate on the inner side of the support base 6, and then the gear plate 7 drives the transmission chain 8 to move, which can facilitate the transmission chain 8 to drive the lifting vehicle 2 to move upward on the inner side of the frame assembly 1. By twisting the chain tensioner 9, the chain tensioner 9 tightens the transmission chain 8 inward, thereby adjusting the overall tension of the transmission chain 8, which can greatly improve the service life of the lifting vehicle 2.
[0024] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
