Splicing variable load lifting mechanism

Abstract

The invention provides a splicing type variable load lifting mechanism, which includes a vertical outer frame, the vertical outer frame includes a plurality of meta-frames spliced ​​up and down, the top of the vertical outer frame is provided with a drive assembly, and the vertical outer frame is equipped with a car Car assembly, the car assembly is slidingly connected with the vertical outer frame, the drive assembly drives the car assembly to move up and down, there are counterweight mechanisms on both sides of the vertical outer frame, the counterweight mechanism is slidingly connected with the vertical outer frame, and the counterweight mechanism is connected to the vertical outer frame. The car components are connected, and the sliding direction of the counterweight mechanism is opposite to that of the car components. The weight of the car is balanced by the counterweight mechanism, which reduces the load on the motor and reduces energy consumption; the rated load of the car can be increased by increasing the number of counterweights in the counterweight mechanism. , no need to replace the high-power motor; the car adopts lifting points and multiple guide wheels, the car will not tilt when the goods enter and exit, and the safety is high.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a splicing variable load lifting mechanism. Background technique [0002] Cranes are one of the commonly used machinery in the construction field, and they play an indispensable role in the construction industry. Commonly used cranes include bridge and cantilever mechanisms. Make full use of the space under the bridge frame to lift materials without being hindered by ground equipment. It is the most widely used and the largest number of hoisting machinery. Cantilever cranes also need to be installed on the outside of the building. The required floor area And the radius of rotation is relatively large, and because the heavy object is suspended in the air, it is very dangerous to encounter the heavy object swinging in the air in the windy weather. In addition, hoisting generally lifts heavy objects directly. In order to cope with loads of different weights, high-power motors ...
