Embodiment Construction

[0012] An embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0013] The energy-absorbing automatic fixed-weight loading device of the present invention mainly consists of an energy-absorbing fixed-weight device, a coal cutting device, a position sensor 11, a hydraulic station 12, an intelligent control cabinet 9 and an intelligent control cabinet 10 for a winch house. The energy-absorbing fixed weight device is directly installed on the tank support beam 20, and is just in time at the bottom of the skip bucket 17 when the skip bucket 17 falls. The energy-absorbing fixed weight device is composed of an elastic buffer assembly arranged on the base 5 and weighing assemblies arranged on both sides of the elastic assembly. 7 and a hydraulic accumulator 8; the weighing assembly is composed of a load cell 2, a base 3 installed below the load cell 2 and a weighing hydraulic cylinder 4 in sequence. When the skip 17 is in pla...

Abstract

The invention is an automatic energy-absorbing type weighing loading device, which is optimum to weighing and loading of vertical shaft skip in old mine, it arranges energy-absorbing weighing device on the tray beam, a hydraulic coal cutting device is arranged on the coal slot correspondent to the entrance of the skip, the oilways of the weighting device and the hydraulic coal cutting device are connected to the hydraulic station, all signal wires are connected to intelligent control cabinet. The device has functions of buffering, detection, control, execution and display. The invention uses PLC to control the hydraulic station to control the load and stop of coal. The structure is simple, and the reliability is high.

Description

1. Technical field [0001] The invention relates to an energy-absorbing automatic fixed-weight loading device, which is especially suitable for the fixed-weight and loading of old mine vertical shaft skip lifting, and also suitable for the fixed-weight and loading of newly-built mine vertical shaft skip lifting. 2. Background technology [0002] At present, the mine shaft skip lifting system built in the 1970s and before the 1970s is still used in our country. Due to the design reasons at that time, during the lifting process of the skip, the coal directly enters from the coal bunker through the coal chute and the tiger gate. Skip, without quantitative bucket or coal feeder device. When loading coal, press down the gate by the skip to open the sliding frame so that the tiger gate enters the skip, and when the skip is full, the skip is lifted out of the wellhead by the hoist. When the skip is lifted on the hoist, the tiger gate is lifted upwards, and the heavy hammer connecte...
