In chemical, metallurgy, grain, building materials, ports, electric power, coal, mining and other bulk material conveying systems, belt conveyor covers of various bandwidths usually need to be waterproof, windproof or dustproof, the conveyor is equipped with a covers, which must be able to open easily because the conveyor needs to be serviced. At present, the open covers of belt conveyor is mainly opened on one side, that is, one side is hinged with the frame of fixed cover. This kind of open covers is usually installed with fixed covers in a certain rate, so that the opening direction and opening position of the whole belt conveyor covers are restricted, which brings great inconvenience to the belt conveyor maintenance.
At present, there are also double-sided open belt conveyor covers, usually this kind of covers is connected with hinges at one-third of its double sides, so the opening degree of this kind of covers is only one-third of the whole covers, which creates less space for overhaul; Not only that, this kind of double-sided open covers is connected by hinges on both sides without supporting structure, so this kind of covers can only be used with fixed covers and cannot be used alone.

The belt machine covers double side open cover includes cover body, frame for fixing cover body and fastening device for fixing cover body on frame, said fastening device is located on both sides of cover body, each fastening device includes live knot bolt, fastening nut and fastening bracket; fastening bracket is fixed on frame, fastening bracket is provided with lateral opening slot with live knot bolt; live knot end of live knot bolt is hinged to cover body, threaded end of live knot bolt The threaded end of the knuckle bolt can be rotated into the lateral opening slot and fixed to the fastening bracket by the fastening nut; when the fastening nut is loosened, the knuckle bolt can be rotated around the knuckle end to disengage the lateral opening slot on the fastening bracket. With the above fastening device, only loosening the nut can separate the live knuckle bolt from the fastening bracket, and the covers can be easily opened from one side, while the fastening device on the other side plays the role of hinge, and at the same time, because of the bolt-nut connection, the support performance is good.
Each fastening device includes an opening and closing handle, the opening and closing handle is fixed on the belt conveyor covers body, and the live joint end of the live joint bolt is hinged with the opening and closing handle. Both sides of the covers of the belt machine can be separated from the fastening bracket by loosening the nut, and the covers can be opened easily from one side, while the fastening device on the other side plays the role of hinge, and the support performance is good because of the bolt-nut connection. It has the advantages of simple structure, convenient and quick opening and closing.
