fig. 2 is the schematic view of the fixing frame connecting chain wheel of the driving mechanism of the elevating platform chain wheel.

In the figure: 1. the device comprises a motor, 2, a rotating shaft, 3, a fixed disc, 4, a first steel wire rope, 5, a fixed frame, 6, a support, 7, a fixed plate, 8, a second steel wire rope, 9, a chain wheel, 10, a fixed block, 11 and a rolling shaft.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: a driving mechanism of a lifting platform chain wheel comprises a motor 1, a rotating shaft 2, a fixed disc 3, a first steel wire rope 4, a fixed frame 5, a support 6, a fixed plate 7, a second steel wire rope 8, a chain wheel 9, a fixed block 10 and a rolling shaft 11, wherein the fixed frame 5 is uniformly arranged on the fixed plate 7, the fixed block 10 is fixedly arranged on the inner wall of the fixed frame 5 in an inserting way through a bolt, the fixed blocks 10 at different positions are respectively and rotatably connected with the chain wheel 9 and the rolling shaft 11, the second steel wire rope 8 is sleeved on the outer wall of the fixed frame 5, the second steel wire rope 8 is in a frame shape, the second steel wire rope 8 in the frame shape can play a reference role in the fixed installation of the fixed frame 5, the fixed installation work of the fixed frame 5 is accurate, the second steel wire rope 8 is clamped in a gap between the outer wall of the fixed frame 5 and a spiral, mount 5 sets up to "U" type structure, mount 5 of U "type structure can avoid its sharp-pointed edges and corners scotch installer's finger part, the gyro wheel part of sprocket 9 laminates with roller bearing 11 mutually, and the 11 outer wall winding of roller bearing of different positions has one section of first wire rope 4, and the both ends winding of first wire rope 4 is at 2 outer walls of pivot, fixed plate 7 was arranged respectively in to pivot 2 preceding, back both ends are peripheral, and 2 one ends of pivot are equipped with support 6, and the 2 other ends of pivot and motor 1's motor shaft fixed connection, it is fixed with fixed disk 3 to alternate on the
