A hydraulic buffer energy storage device and system for skip over-discharging of vertical shaft hoist

Abstract

The invention belongs to the field of over-discharge protection of hoist skips, and in particular relates to a hydraulic buffer energy storage device for over-discharging of hoist skips in vertical shafts. The hoist skip is located above the hydraulic buffer mechanism. The hydraulic buffer mechanism is connected with an accumulator group, a pressure relief part and an oil supply part through an oil pipeline. The accumulator group is connected with an energy storage part through an oil pipeline. The energy storage part, the pressure relief part and the The fuel supply part is connected to the fuel tank through the oil delivery pipe, the hydraulic buffer mechanism is connected to the displacement sensor, the accumulator group is connected to the pressure sensor, and the displacement sensor, the pressure sensor, the energy storage part and the fuel supply part are electrically connected to the controller. The invention can smoothly and safely brake the over-discharged hoist skip, and can also avoid excessive impact and vibration caused by the over-discharged hoist skip, thereby improving the service life of the hoist skip.

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...

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
