Problems solved by technology

[0002] At present, the lifting equipment used for high-altitude operations generally adopts hydraulic system lifting, which requires high manufacturing precision, high manufacturing cost, and the lifting height is limited. Flexibility is limited
This is far from meeting the needs of higher space operations, especially with the development of science and technology, the construction of super high floors, and the fire protection of super high floors are issues that must be considered

Embodiment 1

[0010] Example 1, such as figure 1 , 2 , 4, the self-locking lifting system for working at heights includes a base 1, which is characterized in that: the base 1 is provided with a rotating chassis 2, and the motor 3 and the support 4 are arranged on the rotating chassis 2, the power output shaft of the motor 3 is connected to the first gear shaft 6-1 provided on the support 4 through the reduction gear 5, the first gear shaft 6-1 is provided with the first gear 10-1, the first gear 10-1 meshes with the second gear 10-2 on the first transmission shaft 14-1 located on the support 4, the first transmission shaft 14-1 is provided with the first transmission wheel 19-1, the first gear The shaft 6-1 is connected with the first worm 8-1 provided on the support 4 through the first clutch 7-1, and the first worm 8-1 is connected with the second worm 8-2 provided on the support 4. A worm gear 9-1 is engaged, and the second worm 8-2 is engaged with the second worm gear 9-2 on the first...

Embodiment 2

[0014] Example 2, such as figure 1 , 3 , 4, different from Embodiment 1 is that the third worm 8-3 can also be the third bevel gear 18-3, the third bevel gear 18-3 and the fourth bevel gear located on the lifting arm 15 The fourth bevel gear 18-4 on the worm screw 8-4 is meshed. It transmits power through the meshing of bevel gears.

[0015] The free lifting system for high-altitude operations can be used for high-altitude floor firefighting, high-altitude rescue, high-altitude building cleaning, high-altitude wall painting and other work related to high-altitude operations. For example, installing a camera on the head of the device can monitor the fire location in a high-rise building. At the same time, the structure can transport the fire-fighting pipeline to a designated location, which solves the current difficulty in fire-fighting in high-rise buildings. It can also facilitate the unmanned automatic painting of building walls if the head is equipped with a painting hea...

Abstract

The invention relates to a self-locking type lifting system for working aloft, comprising a base 1. A rotary chassis 2 is arranged on the base 1; a motor 3 and a support 4 are arranged on the rotary chassis 2; a power output shaft of the motor 3 is connected with a first gear shaft 6-1 arranged the support 4 through a reducing gear 5; a first gear 10-1 is arranged on the first gear shaft 6-1; thefirst gear 10-1 is meshed with a second gear 10-2 on a first transmission shaft 14; the first transmission shaft 14-1 is provided with a first transmission wheel 19-1; the first gear shaft 6-1 is connected with a first worm 8-1 through a first relay 7-1; the first worm 8-1 is meshed with a first worm wheel 9-1 on a second worm 8-2; the second worm 8-2 is meshed with a second worm wheel 9-2 on a first driving shaft 11-1; and a lifting device 13 is arranged on the first driving shaft 11-1. A plurality of sections of lifting pieces are connected into an extensible multilevel lifting system through a self-locking power transmission device, thereby the invention has remarkable characteristics of fast lifting, free height adjustment, stopping and turning function after lifting, safety, reliability and convenient use.

Description

technical field [0001] The invention relates to the technical field of lifting equipment for working at heights, in particular to a self-locking lifting system for working at heights. Background technique [0002] At present, the lifting equipment used for high-altitude operations generally adopts hydraulic system lifting, which requires high manufacturing precision, high manufacturing cost, and the lifting height is limited. Flexibility is limited. This is far from meeting the needs of higher space operations, especially with the development of science and technology, the construction of super high floors, and the fire protection of super high floors are issues that must be considered. Contents of the invention [0003] The object of the present invention is to provide a method for the defects in the prior art, which adopts multi-section lifting rods connected through a self-locking power transmission device to form an expandable multi-level lifting system, thereby effec...
