Hoisting stall self-locking device for cement feeding

Abstract

The invention relates to the technical field of cement hoisting and discloses a hoisting stall self-locking device for cement feeding. The hoisting stall self-locking device comprises an outer shaft,the inner wall of the outer shaft is connected with a clamping ring in a sleeved manner, the inner wall of the clamping ring is connected with a rotating shaft in a sleeved manner, a piezoresistor isfixedly connected to the middle portion of the inner wall of the rotating shaft, a return spring is fixedly connected to the middle portion of the inner wall of the rotating shaft, a positive pole plate is fixedly connected to the middle portion of the inner wall of the rotating shaft, a sliding block is movably connected to the middle portion of the inner wall of the rotating shaft, a dielectricplate is fixedly connected to the inner wall of the middle portion of the sliding block, and a negative pole plate is fixedly connected to the middle portion of the inner wall of the rotating shaft. According to the hoisting stall self-locking device for the cement feeding, the rotating shaft drives the sliding block to move, the sliding block drives the dielectric plate to move, then the positivepole plate and the negative pole plate are used in cooperation, so that the effect of controlling on-off of an electromagnet is achieved, the dielectric plate moves relatively, the relative area of the positive pole plate and the negative pole plate is gradually decreased, the voltage between the two pole plates is decreased, at the moment, the working voltage of the piezoresistor is reached, andthe electromagnet is powered on to generate magnetic force repelling a magnetic field and a magnetic block mutually.

Description

technical field [0001] The invention relates to the technical field of cement hoisting, in particular to a hoisting stall self-locking device for cement feeding. Background technique [0002] Foamed cement is to fully foam the foaming agent mechanically through the foaming system of the foaming machine, and mix the foam with the cement slurry evenly, and then go through a series of operations of the foaming machine to form the mold, and then pass through the natural curing plant. A new type of lightweight thermal insulation material containing a large number of closed pores is formed. Due to the large volume of the container for large-scale production of cement, it is necessary to use hoisting equipment to hoist, transport and load the cement. [0003] Due to the heavy weight of the cement and the container, many people are required to operate the hoisting equipment. The hoisting equipment is mainly used in conjunction with pulleys, wire ropes and cranes. The rapid fall dur...
