Shockproof hoist

Abstract

The invention discloses a shockproof hoist, comprising a machine body, wherein two sides of the inner cavity of the machine body are provided with supporting frames; the top of each supporting frame is fixedly connected with a connection beam and a motor; the output of the motor is connected with a roller; a steel wire rope is sleeved outside the roller; the outer side of the roller is connected with a fixing rod by the steel wire rope;a lift plate is connected with the bottom of the fixing rod; the bottom of the lift plate is fixedly connected with a support rod; a shockproof device is set outside the support rod; the shockproof device comprises a substrate; the two inner walls of the substrate are provided with sliding slots; the inner cavity of each sliding slot is in sliding connection with a sliding card plate; and the bottom of the connection rod is fixedly connected with a second pressing plate.The shockproof lift is convenient to absorb the shock and impact energy by setting an inner spring and an outer spring so as to reduce the vibration of the lift, and then the lift can fall stably.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an anti-vibration elevator. Background technique [0002] The modern elevator is the product of the invention of the steam engine in the 19th century. In 1845, the first elevator was born, and the liquid used at that time was water. In 1853, the American Elisa Otis invented the automatic safety device, which greatly improved the steel industry. Safety of cable traction lifts. [0003] With the rapid development of the national economy, multi-storey buildings rise from the ground. In the construction of high-rise buildings, construction elevators and other machinery are often used for vertical transportation. The vibration generated by the elevator when it lands is easy to damage certain items, and it is also harmful to construction workers. An unsafe factor also causes damage to the body and reduces the service life. Due to reasons such as mechanical use or improper management...

[0003] With the rapid development of the national economy, multi-storey buildings rise from the ground. In the construction of high-rise buildings, construction elevators and other machinery are often used for vertical transportation. The vibration generated by the elevator when it lands is easy to damage certain items, and it is also harmful to construction workers. An unsafe factor that also causes damage to the body and reduces the service life. Due to reasons such as mechanical use or improper management, the lift directly falls and collides with the ground, causing major safety accidents
