Abstract

Disclosed is a rail type spiral automatic tensioning device. The rail type spiral automatic tensioning device comprises a tensioning vehicle, a guide rail, a lead screw, a speed reducer, a motor and an electric control cabinet. The tensioning vehicle is arranged in the guide rail, a roller which is used for conducting tensioning on a rubber belt is fixedly connected with the upper portion of the tensioning vehicle, and a lead screw nut which is connected with the lead screw in a threaded mode is arranged on the bottom surface of the tensioning vehicle. The input end and the output end of the speed reducer are connected with the motor and the lead screw through couplings, a power line of the motor is connected with the interior of the electric control cabinet, and an external power source is arranged in the electric control cabinet. According to the rail type spiral automatic tensioning device, the floor type arrangement is adopted by the guide rail, and therefore the integral rigidity of the device is improved, and the rail type spiral automatic tensioning device is particularly suitable for large-stroke tensioning working conditions.

Description

technical field [0001] The invention belongs to the technical field of belt conveyors, in particular to a track-type spiral automatic tensioning device. Background technique [0002] For the belt conveyor to operate normally, the conveyor belt must have a certain tension. Only when the conveyor belt has a certain tension can there be enough friction between the conveyor belt and the driving roller to ensure the normal operation of the conveyor belt driven by the driving roller. The tensioning device is an auxiliary device that provides tension for the normal operation of the belt conveyor, and is indispensable in the conveyor belt transportation system. [0003] At present, the belt conveyor tensioning devices mainly include: hydraulic tensioning, screw tensioning, manual winch tensioning, heavy hammer tensioning and so on. Due to the adjustable tension and stroke, the hydraulic tensioning device has become a commonly used tensioning method for large-scale belt conveyor be...
