Belt sway switch is one of important protection of the belt, but we plant against deviation protection refuse action, as the angle of deviation switch does not install appropriate, distance is not suitable belt sway switch and conveyor belt ,and the bad deviation switch can not be replaced as belt can not stop running, often due to deviation damage to the belt, affect the stability of coal handling system. for the above ,invented a new type of angle, height and distance adjustable deviation switch mounting bracket, thorough solve the problems of belt against deviation. The defect of current belt sway switch protection
There are many disadvantage in belt sway switch, which seriously affect the reliability and stability of the belt sway switch.
1.It is difficult to adjust the installation height and angle. The fixed support of belt sway switch should be welded before installation. The angle between the switch vertical roller and the belt must be determined by welding, which cannot be changed or adjusted. At the same time, the installation height should be determined before weld, the deviation rate is high.
2.It is difficult to determine the installation distance from the conveyor belt. The distance between the belt sway switch and the conveyor belt edge should also be determined before welding. The accuracy is very low, which will affect the installation of the belt sway switch.
2.3 it is difficult to replace the belt sway switch. In the conveyor belt operation, the belt sway switch is damaged, and the conveyor belt must be stopped for inspection and replacement. When the running of conveyor system is tensioned, there is no condition to block the conveyor belt, causing further damage of the belt sway switch, or damage to the belt or whole system.
2.4 belt sway switch is easy to be damaged and in a wrong way of operating. When workers clean the coal slime and shovel the coal slime onto the belt, they often damage or even break the electric cable of belt sway switch signal. When the cable is washed with water, water often enters into the water, causing the belt sway switch to send the off-track signal by mistake.
A new type of belt sway switch fixing bracket
In view of many defects of the traditional belt sway switch bracket, a new practical belt sway switch fixing bracket is invented. The belt sway switch installation Angle, installation height and installation distance from the leather belt are all adjustable, which ensures the installation accuracy.
1. The new type of belt sway switch fixed support structure the new type of switch vertical roll Angle, installation height and the distance between the switch and the belt adjustable belt sway switch fixed support, the belt sway switch and signal cable junction in galvanized pipe, to prevent the flushing water into. In this way, it can prevent the damage or break of the deviation switch signal cable, and the wrong transmission of water in the cable joint.
