Embodiment Construction
[0029] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.
[0030] Implementation of the present invention provides a hydraulically controlled broken belt arresting device for belt conveyors, including a brake mechanism, a hydraulic system, an electrical control device and a broken belt signal detection device, wherein the composition of each part is to brake The mechanism is straddled and fixed at an appropriate position on the belt conveyor frame, and is respectively connected with the corresponding parts of the hydraulic system, the corresponding part of the electrical control device and the corresponding part of the broken belt signal detection device, and is detected by the broken belt signal. The device realizes that the hydraulic control system can capture the broken belt part of the belt conveyor.
[0031]In the above-mentioned overall technical scheme, the designed braking mechanism includes two parts, ...

A hydraulic-control broken belt catching device for a belt-type conveyor is formed by a brake mechanism which is arranged on a machine frame of the belt-type conveyor in a cross mode, and is connected with a hydraulic system, an electric-control device and a broken belt signal detection device. The brake mechanism is composed of an upper catching brake mechanism and a lower catching brake mechanism, a belt respectively penetrates through the upper catching brake mechanism and the lower catching brake mechanism, the broken belt signal detection device carries out detection and judgment according to positive and negative rotation of the belt, variation of belt speed, sudden variation of motor current and variation of tension, a programmable logic controller (PLC) comprehensively processes signals and then transmits the signals to the hydraulic system, an energy accumulator and a pump station supply oil simultaneously to an oil cylinder, an oil rod extends out rapidly, and the upper catching brake mechanism and the lower catching brake mechanism simultaneously catch a broken belt. A control system detects the work state of the broken belt through multiple signals, the signals are collected more accurately, mistaking motions are prevented from occurring, and the energy accumulator and the hydraulic pump station supply the oil simultaneously. In addition, the differential motion design of the oil cylinder largely shortens the response time of catching, and improves the catching efficiency.
Description
technical field [0001] The invention relates to a hydraulically controlled broken belt arresting device for a belt conveyor, specifically, a hydraulically controlled arresting device for a belt conveyor with a large inclination upward or downward when the belt is broken. Background technique [0002] Belt conveyors play a pivotal role in coal mine transportation. In order to meet the needs of production, conveyor belts are developing in the direction of long distances and large inclinations. Due to the long-term high-load operation of the belt and some unexpected factors, such as gangue directly sucking the belt or The metal object directly blocks the belt, and the belt joint is fatigued, which will cause the belt to break suddenly; especially for the upper belt conveyor with a large inclination, long belt and heavy load, once the broken belt slides down and the reverse accident caused by the failure of the backstop , it will destroy the belt conveyor frame, damage the equip...
