Problems solved by technology
At present, the vertical shaft mainly adopts manual unloading, which has low efficiency
[0003] In addition, the end switch of the main shaft hoist mostly adopts a travel switch or a magnetic switch, which has high cost, complex structure, long maintenance process, difficulty in judging whether the components are good or bad, high failure rate, low action sensitivity, and large parking position error. The lifting container is too high or too low, resulting in difficulty in loading or unloading, affecting the lifting time, and the damage rate of the end switch is high. Once damaged, production must be stopped and replaced in the wellbore, which takes a long time to troubleshoot

The invention provides a vertical shaft full-automatic unloading system, belongs to the technical field of the underground hoisting system and mainly solves problems of low vertical shaft hoister unloading efficiency and travel switch vulnerability. The vertical shaft full-automatic unloading system comprises a touch switch, an unloading deivce and an automatic control line and is characterized in that the touch switch comprises a flexible electrode (2) and a skip bucket (3), wherein the flexible electrode (2) is fixed on a vertical shaft wall (1), the skip bucket (3) is made of metal, and an unloading gate (7) is arranged on one side on the lower portion of the skip bucket (3). The unloading deivce comprises a cylinder (4), an outward bending guide rail (6) and a switching off hook (5), wherein one end of the switching off hook (5) is hinged to a piston of the cylinder, and the other end of the switching off hook (5) slides in the guide rail (6). The flexible electrode (2) is a steel wire rope electrode. The automatic control line comprises a linked line of the touch switch and an electronic control switch of the unloading device and an automatic reset electronic control line of the unloading device.
Description
technical field [0001] The invention belongs to the technical field of underground hoisting systems, and in particular relates to a vertical well automatic unloading system. Background technique [0002] The hoisting system of the main shaft is the throat link of the coal mine, and the hoisting speed of the hoist is one of the determining factors of the output of the coal mine. The hoisting speed of the main shaft hoist is mainly determined by factors such as motor, reducer, drum, sky wheel, wire rope weight, shaft depth, load weight, loading system, unloading system, circuit control mode, etc., among which the control of unloading time in the unloading system plays a decisive role. factor. At present, the vertical shaft mainly adopts manual unloading, and the efficiency is low. [0003] In addition, the end switch of the main shaft hoist mostly adopts a travel switch or a magnetic switch, which has high cost, complex structure, long maintenance process, difficulty in judg...
