Description

Technical Field

[0001] The utility model relates to the technical field of lifting equipment, and more specifically, to a transmission component of a lifting mechanism. Background Art

[0002] The lifting mechanism is composed of a first bracket and a second bracket. The second bracket is installed on the first bracket, and the lifting is completed by the movement of the second bracket. A transmission assembly for driving the lifting of the second bracket is installed at the bottom of the first bracket. The transmission assembly will occupy the space at the bottom of the second bracket, so that the second bracket cannot be completely retracted to the bottom of the first bracket, resulting in the second bracket being one section higher than the first bracket when it descends to the lowest point, thereby increasing the overall height of the equipment. When the lifting mechanism wants to enter a car with a lower height, it may not be able to enter because the second bracket is one section higher than the first bracket. Although directly lowering the height of the second bracket can solve the stability of entering a car with a lower height, it will cause the overall travel of the lifting mechanism to be insufficient, which will not be able to meet the use scenarios with higher heights. Utility Model Content

The support column 110 comprises a first support plate 111 and a second support plate 112, and the bottoms of the first support plate 111 and the second support plate 112 are connected by a third support plate 113. Of the two support columns 110, a first rotating shaft 400 and a motor 114 for driving the first rotating shaft 400 to rotate are installed on the third support plate 113 of the first support column 110, and a second rotating shaft 500 is installed on the third support plate 113 of the other support column 110. The second rotating shaft 500 includes a first semi-shaft 510 and a second semi-shaft 520. Two first transmission wheels 410 are installed on the first rotating shaft 400. The first transmission wheel 410 is a sprocket. The positions of the first semi-shaft 510 and the second semi-shaft 520 correspond to the positions of the two first transmission wheels 410 respectively. The first semi-shaft 510 and the second semi-shaft 520 are both installed with a second transmission wheel 530. The second transmission wheel 530 is a sprocket. The first transmission wheel 410 and the second transmission wheel 530 are connected by a first transmission belt 600. The first transmission belt 600 is a chain, so that the rotation of the first transmission wheel 410 can drive the rotation of the first semi-shaft 510 and the second semi-shaft 520.

[0022] The first transmission wheel 410, the first semi-axle 510 and the second semi-axle 520 are all equipped with a third transmission wheel 420, which is a sprocket.
