Conjoined multi-tape type power lifting device

Abstract

The invention discloses a conjoined multi-tape type power lifting device. The conjoined multi-tape type power lifting device is characterized in that the conjoined multi-tape type power lifting device comprises a driving unit, a transmission unit, a lifting unit, a bearing platform and a monitoring unit. The driving unit can be a motor, and a first rotary shaft is arranged at the power output end of the driving unit. The transmission unit comprises a first gear, a second gear and a second rotary shaft, the first gear is connected with the first rotary shaft in a matched mode, the second gear is connected with the second rotary shaft in a matched mode, and the first gear is meshed with the second gear. The lifting unit comprises two pieces of tape and is of a rolling structure, a central end is formed in the lifting unit, the relative outer end of the lifting unit is an outer tail end, and the central end of the lifting unit is respectively connected with the first rotary shaft and the second rotary shaft. The bearing platform is arranged on the top of the lifting unit, and is combined with the outer tail ends of the tape, and the monitoring unit is arranged on the bearing platform. The conjoined multi-tape type power lifting device has the advantages that the structure is simple, control is easy, the lifting stroke ratio is large, the device can ascend to a large height with few materials, and deformation and shimmy are avoided.

Description

technical field [0001] The invention relates to a lifting mechanism, in particular to a conjoined multi-tape power lifting device. Background technique [0002] Lifting mechanisms are widely used in various mechanical fields. For example, as far as the power lifting device is concerned, the height of the total device before it is raised is low, and the height of the total device becomes higher after it is raised. For the lifting device with the function of raising the base machine out of the air (similar to the elevator pulled at the highest point) device), the known structures generally include: 1. The frame-shaped member cable type, which has the advantages of high lift and large top load, but the disadvantage is that the mechanism is complicated, the height of the base section is high, and it cannot be vertically lifted. Space constraints. [0003] 2. X-type component hydraulic push rod type: the advantage is that it can be lifted vertically without space restri...

3. Zigzag component motor type: the advantage is that it can be lifted vertically, but the disadvantage is that the mechanism is complicated, the base section has a certain lift ratio height, and the lift and operating space are limited.

4. A-type tape measure member motor type: the advantage is that it can be lifted vertically, and the disadvantage is that the base section has a certain necessary height, and the cup-shaped object will also shake

5. Tubular member push cable type: the advantage is that it can be lifted vertically without space restrictions, the disadvantage is that the top load is small and easy to shake, the base section has a certain lift ratio height, and the lift is limited

The various lifting mechanisms mentioned above still have limitations or lacks, and they still cannot meet the specific needs in actual application.
