This type of conveyor has the characteristics of being environmentally friendly, flexible arrangement of the conveying line along a spatial curve, large conveying angle, adaptability to complex terrain conditions, and long single-machine transportation distance. Therefore, pipe-belt conveyors have been widely used in various material transportation occasions.

[0003] During the operation of the belt conveyor, the pull-rope switch plays a vital role. The pull-rope switch is mainly used for the emergency stop of the belt conveyor. When the wire rope is pulled, the encoder of the pull-rope switch will monitor the change of the switch state and output the control signal for emergency stop or alarm to the main controller through the bus. Since the pull-rope switch is easy to install, the switch conversion is reliable, and it can prevent the expansion of accidents in time, it has been widely used in transportation sites. At present, on the belt conveyor, the rollers are arranged on the plate surface of the roller window frame plate. The length of the belt conveyor generally ranges from 500 meters to tens of kilometers. The pull-rope switch is arranged in a group every 30 meters along the length of the belt conveyor, which is convenient for on-site patrol personnel to pull the nearest pull-rope switch in time after discovering the danger and make an emergency stop.

[0004] However, the bracket of the pull-cord switch is generally welded on-site to the surface of the window frame board. Workers need to carry heavy welding machines and weld one by one along the length of the pipe belt machine, which is a large workload. In addition, when welding the pull-cord switch bracket, the window frame board has been galvanized for anti-corrosion, which will increase the difficulty of on-site welding. For the sake of aesthetics, it is necessary to repaint after welding, which further increases the workload. Utility Model Content
