Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mine belt protection, in particular to a belt protection structure capable of high sensitivity, having an alarm power-off function, and realizing the purpose of protecting the long-distance and large-area tearing of the belt, especially a mine belt longitudinal tearing protection device. BACKGROUND

[0002] The mine belt conveyor is mainly used in the process of coal mining, production, transportation and processing. The coal mine belt conveyor has the characteristics of large transportation capacity, complex working environment, strong bearing capacity and long transportation distance.

[0003] Since the mine belt conveyor is used in a relatively harsh environment, a special belt protection device is usually configured for it. At present, the electrode type belt longitudinal tearing protection mode is mainly used to realize the longitudinal tearing of the belt. For example, a new belt conveyor anti-tearing device is disclosed in the patent with the patent number CN217894195U, which mainly includes a conveyor belt, a first rack and a second rack arranged on both sides of the conveyor belt, a steel wire rope and a contact switch. The contact switch is fixed on the second rack, and the contact switch includes a shell, both sides of the shell are provided with a carrier plate, the carrier plate is provided with an electrode, a movable plate is slidably connected in the shell, a spring is arranged between the movable plate and the shell, a conductor sheet is arranged on one side of the movable plate close to the electrode, an L-shaped plate is further arranged on the movable plate, and a sliding block is arranged between the L-shaped plate away from the movable plate and the shell. One end of the steel wire rope is fixed on the first rack, and the other end of the steel wire rope penetrates the shell and extends downward to be fixed on the top of the sliding block.

In addition, the electrode type structure of the longitudinal tearing protection structure of the belt conveyor has low sensitivity and short service life.

[0005] However, the underground belt lane is dark and humid all year round, and the use environment is limited. The electrode is easily oxidized by moisture, which can easily reduce its sensitivity.

[0056] Specific working principle:

[0057] The mining belt longitudinal tear protection device in the application can be used with the first mining belt 1 and the second mining belt 2, realizes rapid detection when the belt under the transfer state appears longitudinal tear damage, and can utilize the first detection unit to detect the first mining belt 1 and the second detection unit to detect the second mining belt 2 when the mining belt is detected. The detection accuracy of the first detection unit and the second detection unit can be set to be the same or different. Specifically, the detection of the radiation detection module on the mining belt directly above it is mainly designed based on the leakage of the belt after a certain degree of longitudinal tear. After the leakage of the belt surface transporting blocky materials 3, the blocky materials 3 will directly fall on the radiation detection module below through the leakage position. The pickup of the falling blocky materials 3 by the radiation detection module can ensure that the blocky materials 3 trigger the radiation detection module through the accumulation site, so that the radiation detection module can receive the trigger signal and transmit it to the external control system, so that the control system can send a signal that the current mining belt has appeared longitudinal tear, and timely control the corresponding mining belt to stop and repair, thereby preventing the current mining belt from continuing to appear longitudinal tear, effectively ensuring that the belt transition longitudinal tear problem occurs.

[0058] When the blocky materials 3 fall on the upper part of the horizontal mounting seat 6, they will accumulate on the surface of the horizontal mounting seat 6. When the amount of blocky materials 3 is large, a certain height will be formed and block the multi-position radiation assembly. After being blocked, the multi-position radiation assembly is triggered by the trigger signal.

[0059] The protection device can quickly receive the current mining belt longitudinal tear state by detecting the leaked blocky materials 3 after the belt longitudinal tear. The whole adopts the radiation type sensor for rapid detection, and the detection sensitivity is high. The protection device can simultaneously detect the second belt when the mining belt longitudinal tear occurs. When the first mining belt 1 and the second mining belt 2 in the mining belt appear longitudinal tear damage, the detection can be quickly completed. Similarly, the idea of adjusting the extension length of the height-adjusting electric cylinder 8 to adjust the longitudinal tear detection accuracy is innovatively proposed. The radiation detection module adopts multiple groups of radiation sensor emitting ends 9 and radiation sensor receiving ends 10 arranged along the width direction of the mining belt, which can ensure timely capture of the falling blocky materials 3, and can ensure that the falling blocky materials 3 can complete the shielding and triggering of at least one group of radiation sensor emitting ends 9 and radiation sensor receiving ends 10 on both sides of the current position.
