Abstract
The utility model provides an electric tensioning device of a cantilever belt conveyer. The electric tensioning device of the cantilever belt conveyer solves the problems that both ends of a roller of an existing tensioning device are adjusted separately to lead to deviation of the belt conveyer and the distance between the roller and a baffle plate can change when the position of the roller changes. The electric tensioning device of the cantilever belt conveyer is characterized by comprising an electric push bar and a tensioning mechanism, wherein the electric pushing bar comprises that a reducing motor drives a gear transmission mechanism, the axial hole of the driven gear of the gear transmission mechanism fixes a nut the nut is matched with a screw, and one end of the screw is hinged to the cross beam of the frame of the tensioning mechanism; the tensioning mechanism comprises that the baffle plate is hung on a protection cover, and the shaft of the tensioning roller of the cantilever belt conveyer is mounted on a bearing seat through a bearing. The electric tensioning device of the cantilever belt conveyer has the advantages that deviation of the belt conveyer during adjustment can be avoided and the relative positions of the tensioning roller and the baffle plate keep unchanged.
Description
Technical field
The utility model relates to cantilever belt conveyor tightening device, is a kind of electric tensioner specifically.
Background technology
Tightening device is requisite parts in belt conveyer.The tightening device that cantilever belt conveyor is used mostly at present is spiral tightening device or Hydranlic tensioner, these tightening devices need to regulate respectively belt tensioning drum two ends, easily cause belt tensioning drum and other cylinder axis not parallel, easily cause Auto-rectification Device for Belt Conveyer; Therefore and these tightening devices only change the position of belt tensioning drum and carry out Conveyer Belt, when change belt tensioning drum position, the relative distance of belt tensioning drum and striker plate will change, for adapt to discharging track also needs regulate position and the angle of striker plate.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model is to provide the electric tensioner on a kind of cantilever belt conveyor.
The purpose of this utility model is achieved in that it is comprised of electric pushrod and stretching device, is arranged on cantilever belt conveyor cantilever; Electric pushrod is, reducing motor driven wheel transmission device, the axis hole Fixed Nut of the driven gear in gear drive, stretch out from the axis hole of driven gear at the two ends of screw, by two bearings, located respectively, be fixed on the bearing seat backup bearing on gear drive housing, screw coordinates with leading screw, leading screw is parallel with reducing motor axle, and the crossbeam in one end of leading screw and stretching device framework is hinged; Stretching device is, guard shield is welded on framework, and striker plate is hung on guard shield, slide block on framework is placed on slideway, slideway is arranged on cantilever belt conveyor cantilever, and the axle of the belt tensioning drum of cantilever belt conveyor is arranged on bearing seat by bearing, and bearing seat is fixed on framework.
Working process is: when reducing motor rotates, driven wheel transmission device and screw rotation successively, due to screw by two bearings in axial location, leading screw axially moves, drive stretching device framework to move axially, and then the striker plate on framework and belt tensioning drum together move thereupon, adjusted tensile force.
Compared with prior art, good effect of the present utility model is: motorized motions tensioning, and stroke of tension regulates simple, reduces the time of adjusting belt tensioning drum, belt conveyer sideslip not during adjusting; Stretching device integrated moving, can make the relative position of belt tensioning drum and striker plate constant.
