Problems solved by technology

[0003] The belt tensioning device in the prior art also has a hydraulic tensioning device, but generally a hydraulic cylinder is used to directly push and pull the belt reversing roller, and the reversing roller can move in the same direction through the expansion and contraction of the oil cylinder, so as to achieve the effect of belt tensioning , the force of the oil cylinder in this form of tensioning device is the multiple of the tension force of the belt, and the force of the oil cylinder increases with the increase of the belt tension force. When the belt needs a large tension force, the pressure of the oil cylinder is large, and the cost of the oil cylinder high

Abstract

The invention relates to the technical field of loading and unloading for large-sized dry bulk, in particular to a belt tensioning device. The device comprises a supporting base, a retractable drivingmechanism and a diverted roller. The supporting base is provided with slide grooves, and slide blocks are slidingly arranged in the slide grooves. The retractable driving mechanism is arranged on thesupporting base, and the slide blocks are driven to slide in the slide grooves when the retractable driving mechanism extends and retracts. The diverted roller is used for tensioning a transmission belt, the movement direction of the diverted roller is perpendicular to that of the slide blocks, the end of the diverted roller is connected with the slide blocks through connection rods, the first end of each connection rod is hinged to one side block, the second end of each connection rod is hinged to one end of the diverted roller, and an included angle a between the tensioning direction of thediverted roller and the connection rods is smaller than 45 degrees. A belt conveyor of a cantilever-type bucket-wheel stacker-reclaimer comprises the belt tensioning device. According to the belt tensioning device, through horizontal extension and retraction of an oil cylinder, the diverted roller moves up and down, the effect of tensioning the belt is achieved, and the belt tensioning device hasthe advantages of being low in weight and capable of achieving the small pressure of the oil cylinder.

Description

technical field [0001] The invention relates to the technical field of large-scale dry bulk cargo loading and unloading, in particular to a belt tensioning device and a belt conveyor of a cantilever bucket wheel stacker and reclaimer. Background technique [0002] The belt tensioning method of the traditional cantilever-type bucket-wheel stacker-reclaimer adopts the heavy hammer type, and the weight of the heavy hammer is several tons or even more than ten tons, which puts forward higher requirements on the strength of the steel structure. [0003] The belt tensioning device in the prior art also has a hydraulic tensioning device, but generally a hydraulic cylinder is used to directly push and pull the belt reversing roller, and the reversing roller can move in the same direction through the expansion and contraction of the oil cylinder, so as to achieve the effect of belt tensioning , the force of the oil cylinder in this form of tensioning device is the multiple of the ten...
