Abstract

The invention discloses a large-stroke vertical lifting mechanical device with double ball screws for a narrow space, relates to a vertical lifting mechanical device, and aims to solve the problem that various existing lifting machines difficultly meet the requirement of the narrow space of a large-aperture optical element repair device in assembly. The ball screws are rotatably connected with ball screw bearing supporting seats and a bottom mounting plate, side supporting plates are connected with the ball screw bearing supporting seats and a bottom connecting plate, ball screw nuts and the ball screws are screwed, the ball screw nuts and square flange linear bearings are connected with a movable slider, polished shafts are connected with the ball screw bearing supporting seats and the bottom connecting plate, one square flange linear bearing is slidably sleeved on each polished shaft, worm gears are fixedly mounted on the ball screws, synchronous pulleys are fixedly sleeved on synchronous pulley shafts, the synchronous pulley shafts are connected with the bottom connecting plate through synchronous pulley bearing blocks, the first synchronous pulley shaft is connected with a worm engaged with the worm gears, and the second synchronous pulley shaft is connected with a direct current geared motor. The large-stroke vertical lifting mechanical device is used for assembling the large-aperture optical element repair device.

Description

technical field [0001] The invention relates to a vertical lifting mechanical device. Background technique [0002] With the development of social science and technology, lifting platforms are widely used in all walks of life. Whether it is in the field of mechanical engineering, civil engineering, or in the construction industry, it is necessary to assemble mechanical equipment or adjust the height of instruments, etc. , all kinds of lifting platforms play an extremely important role. The electric lifting platform has the characteristics of small size, light weight, convenient movement, and good stability; at the same time, it can exert the highest lifting capacity in a small space. Therefore, it is widely used in the installation and maintenance of power lines, lighting appliances, elevated pipelines, etc. The elevator market is very prosperous, and various elevator products are designed and produced. However, for some extreme occasions where a large lifting stroke is r...
