Energy-saving protecting device for slack rope of hoisting system

Abstract

The invention provides an energy-saving protecting device for a slack rope of a hoisting system. The energy-saving protecting device for the slack rope of the hoisting system comprises a spindle, a wheel, a bearing block, a first encoder, steel wire ropes, a counter weight, a tail rope, a hoisting container, a first guiding wheel and a second encoder. The counter weight is connected with the hoisting container through a friction wheel device, in a process of hoisting the hoisting container, the torque and the work of hoisting equipment are reduced, therefore, the service life of the equipment is prolonged, and energy consumption of the device is reduced. Meanwhile, the first encoder is arranged on the spindle of the friction wheel device, by the first encoder and the second encoder arranged on a hoister, the movement circumstances of the friction wheel device and the hoister can be detected in real time, possible critical circumstances such as breakage of the slack rope are judged, a control cabinet makes corresponding actions, and therefore, the function of preventing the slack rope from being broken is fulfilled.

Description

technical field [0001] The invention relates to the technical field of hoisting machinery, in particular to an energy-saving protection device for loose ropes of a hoisting system. Background technique [0002] At present, there are more and more high-rise residential buildings, and elevators are frequently used. In the production process of mines, lifting equipment belongs to the "throat" part and plays a vital role. "Coal Mine Safety Regulations" strictly requires lifting equipment to be equipped with a loose rope protection requirement. Most mines use a loose rope switch installed at the bottom of the wire rope outlet, which simply cannot track the lifting container and protect the loose rope in the shaft. , so that when the cans are stuck, they continue to be lowered to cause the phenomenon of falling cans, which has a large safety hazard.

Problems solved by technology

"Coal Mine Safety Regulations" strictly requires lifting equipment to be equipped with a loose rope protection requirement. Most mines use a loose rope switch installed at the bottom of the wire rope outlet, which simply cannot track the lifting container and protect the loose rope in the shaft. , so that when the cans are stuck, they continue to be lowered to cause the phenomenon of cans falling, which has a large safety hazard

[0003] When the wire rope breaks, the current method is to lift the anti-fall device installed on the container to prevent the container from falling. This method has no remedial measures. Once the anti-fall device fails, you can only watch the tragedy happen, and there are potential safety hazards

Moreover, there are currently many mine hoisting equipment that are single-rope winding hoists and hoisting winches. There is no counterweight in the hoisting process, resulting in high production costs and a lot of energy waste.
