Automatic control anti-stall lifter for freight

Abstract

The invention relates to the technical field of freight equipment, and discloses an automatic control anti-stall lifter for freight, which comprises a shell, a lifting groove is formed in the shell, a lifting rod is movably connected in the lifting groove, control wheels are movably connected to two sides of the shell, symmetrical positive plates are fixedly connected in the control wheels, symmetrical negative plates are fixedly connected to the interiors of the control wheels, and symmetrical piezoresistors are fixedly connected to the interiors of the control wheels. According to the automatic control anti-stall lifter for freight, through mutual cooperation of electrode columns and expansion blocks, when a product stalls, the electrode columns are powered on to work, the electrode columns stimulate the expansion blocks, the expansion blocks are subjected to a chemical reaction, the expansion blocks are decomposed to generate a large amount of gas, and the air pressure in the expansion grooves is rapidly increased; and pistons move outwards under the action of air pressure to drive clamping blocks to be clamped with clamping grooves, so that the movement of the lifting rod is limited, and the function of automatic control and stall protecting of the product is realized.

Description

technical field [0001] The invention relates to the technical field of freight equipment, in particular to an elevator with automatic control and stall prevention for freight. Background technique [0002] An elevator is a hoisting machine that transports people or objects vertically. It also refers to equipment for vertical transportation in logistics systems such as factories and automatic warehouses. The elevator is often equipped with various plane conveying equipment as a connection of different height conveyor lines. device, during the use of the elevator, the moving speed of the lifting platform often exceeds the normal working range, causing the danger of damage to the transported goods, causing losses to the user, and failing to meet the needs of the user. [0003] During the transportation and use of the elevator, due to the fluctuation of the circuit voltage, the lifting power will suddenly increase, which will cause the moving speed of the lifting platform to inc...
