A protection device for preventing breakage of belt conveyor

Abstract

The invention discloses a protective devicefor preventing fracture of a belt conveyor. The protective device includes a base, the upper end of the base is provided with a U-shaped bracket, the side wall of the U-shaped bracket is provided with a sliding groove, and both ends in the sliding groove are provided with sleeves correspondingly; and the sleeves are internally embedded with springs and sliders, sliding rods and connecting plates are arranged outside the sleeves, wherein one ends of the sliding rods are inserted into the sleeves and connected with the sliders, the other ends of the sliding rods are connected with the connecting plates, the side walls, penetrating through one face of a sliding groove, of one ends of the connecting plates extend out of the U-shaped bracket, and are connected with arranged top blocks, the side walls, penetrating through the other face of the sliding groove, of the other ends of the connecting plates extend out of the U-shaped bracket, and are connected with arranged fixing plates. The protection device for preventing the fracture of the belt conveyor alarms when a belt fractures, and has the functions of daily protection of the belt and emergency stop of the belt, and through cooperative use of the two, the protective effect on a conveyor belt 34 and an operator are achieved.

Description

technical field [0001] The invention relates to the technical field of ore mining machines, in particular to a protection device for preventing belt conveyors from breaking. Background technique [0002] An important link in ore production is the ore transportation system. At present, the ore transportation system mainly adopts belt conveyors. In the ore transportation, the ore belt conveyor generally needs to carry out long-distance, long working hours and overweight transportation. Due to problems such as uneven force on the belt, deviation of the ore falling position, and large transportation inclination during use, it may cause problems such as The mine belt is slack, slipping, deviation, broken belt, etc. [0003] Most of the existing conveyor belts are equipped with alarm devices. When the ore conveyor belt suddenly breaks due to quality problems such as overload and aging and improper operation, the tight ore conveyor belt will slide down rapidly due to the break, an...

AI Technical Summary

Problems solved by technology

In the ore transportation, the ore belt conveyor generally needs to carry out long-distance, long working hours and overweight transportation. Due to problems such as uneven force on the belt, deviation of the ore falling position, and large transportation inclination during use, it may cause problems such as Mining belt looseness, slippage, deviation, broken belt, etc.

[0003] Most of the existing conveyor belts are equipped with alarm devices. When the ore conveyor belt suddenly breaks due to quality problems such as overload and aging and improper operation, the tight ore conveyor belt will slide down rapidly due to the break, and even fly out to hit the work. Personnel, and the existing device can only alarm when it breaks, and does not have the function of daily protection of the belt and the function of emergency stop belt, which leads to the failure of effective treatment after the belt breaks, resulting in subsequent casualties and equipment losses. situation
