Problems solved by technology

In the traditional skip over-discharge protection measures, anti-collision sleepers or rubber protection devices are often installed at the designated parking position of the skip above the underground ground. When the skip over-discharge speed is too high (or the rope breaks), the traditional protection device It is difficult to absorb the impact energy of over-discharge of the skip, and it is easy to damage the underground equipment, resulting in unpredictable economic losses and casualties, which seriously affects the vertical transportation operation of the hoist skip

Abstract

The invention belongs to the field of elevator skip bucket over-release protection, and particularly relates to a vertical shaft elevator skip bucket over-release hydraulic buffer energy storage device which comprises a vertical shaft. An elevator skip bucket is hung on the inner side of the vertical shaft, a hydraulic buffer mechanism is arranged on the inner side of the vertical shaft, and the elevator skip bucket is located above the hydraulic buffer mechanism. The hydraulic buffer mechanism communicates with an energy accumulator set, a pressure relief part and an oil supplementing part through oil conveying pipes, the energy accumulator set communicates with an energy storage part through an oil conveying pipe, the energy storage part, the pressure relief part and the oil supplementing part communicate with an oil tank through oil conveying pipes, the hydraulic buffer mechanism is connected with a displacement sensor, and the energy accumulator set is connected with a pressure sensor. The displacement sensor, the pressure sensor, the energy storage part and the oil supplementing part are electrically connected with a controller. By means of the vertical shaft elevator skip bucket over-release hydraulic buffer energy storage device, over-released elevator skip bucket can be stably and safely braked, the over-released elevator skip bucket can be prevented from generating overlarge impact vibration, and the service life of the elevator skip bucket is prolonged.

Description

technical field [0001] The invention belongs to the field of over-discharging protection of hoist skips, in particular to a hydraulic buffer energy storage device and system for skip over-discharging of vertical shaft hoists. Background technique [0002] During the heavy load and long-distance vertical conveying process of the vertical shaft hoist, the wire rope of the hoist is prone to breakage, especially when the hoist skip is lowered to the designated position in the underground, because the speed braking of the skip is not complete, the skip often has a certain The speed hits the underground parking position, that is, the skip is over-discharged. In the traditional skip over-discharge protection measures, anti-collision sleepers or rubber protection devices are often installed at the designated parking position of the skip above the underground ground. When the skip over-discharge speed is too high (or the rope breaks), the traditional protection device It is difficul...
