Abstract

The invention discloses a hydraulic system of a hydraulic belt coiling device for a belt-type conveyer. The hydraulic system of the hydraulic belt coiling device for the belt-type conveyer comprises a motor pump set (1), a multipath reversing valve group (2), a belt drawing motor (5), a belt coiling motor (6), a rotating motor (7), a belt drawing clamping hydraulic cylinder (8), a fixing and clamping hydraulic cylinder (10) and a lifting hydraulic cylinder (12) and further comprises one-way valves (3), a first bidirectional hydraulic control one-way valve (9), a second bidirectional hydraulic control one-way valve (11) and a third hydraulic control one-way valve (13). In hydraulic oil ways, the multipath reversing valve group (2) is connected with the hydraulic cylinders and the motors, oil inlets of all the hydraulic oil ways are provided with the one-way valves (3), and the bidirectional hydraulic control one-way valves are arranged in inlet-outlet oil ways of the hydraulic cylinders respectively. By the adoption of the technical scheme that both the one-way valves and the bidirectional hydraulic control one-way valves are adopted, it is guaranteed that an executing mechanism can stay at the original position when decompression happens to the hydraulic system suddenly, personal safety of operators are guaranteed, and double guarantee is provided for under-shaft safety production.

Description

technical field [0001] The invention relates to a hydraulic system of a hydraulic tape winding device, in particular to a hydraulic system of a hydraulic tape winding device for a belt conveyor. Background technique [0002] The belt conveyor is mainly used for coal transportation in the fully mechanized mining face, and the conveyor is installed in the roadway of the working face. With the progress of fully-mechanized mining, the conveyor belt gradually shortens. When the conveyor belt stored in the belt storage bin is full, the conveyor belt in the storage belt bin needs to be taken out and rolled up for transport. This process is the belt-retracting process of the conveyor belt. The hydraulic belt take-up device is the main equipment for collecting the excess conveyor belt of the belt conveyor. Generally, the hydraulic tape winding device is composed of a motor pump group, a multi-way reversing valve group, a tape motor, a tape motor, a rotating motor, a tape clamping hy...
