The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, a kind of belt conveyer belt Hydranlic tensioner, it is characterized in that: it comprises two fixed pulleys 2,3 that are installed on the dolly 1 that moves about, pedestal 15, is installed in the movable pulley 5 on the cushion cylinder 6 and connects the steel rope 4 of movable pulley, fixed pulley and winch the electric winch on the mounting base 15, cushion cylinder 6, accumulator 8, oil pump 12, control box 13; Described pedestal 15 is the steel structure rectangular frame, and the described dolly 1 that moves about is installed on the left rail of pedestal 15, and its outer end connects with load-transfer device, inner fixedly fixed pulley 2 and fixed pulley 3; Described electric winch comprises the capstan winch 7 that is installed on the pedestal 15, and the change speed gear box 10 that connects with capstan 7, motor 9 are installed on the pedestal 15 successively; Logical support 17 of described cushion cylinder 6 its cylinder ends and pedestal 15 hinge joints, the end of its piston rod is movable pulley 5 fixedly; Described oil pump 12 is installed on the pedestal 15, and connects by the energy storage 8 that hydraulic pipe 19 and level are installed in pedestal 15 middle parts; Setting pressure table 8-1 on the described energy storage 8, and connect with cushion cylinder 6 by hydraulic pipe 19; Described control box 13 is installed on the pedestal 15, and connects with magnetic starter 11 by electric wire 18, and magnetic starter is installed on the pedestal 15 and by electric wire and connects with motor 9; Described steel rope 4 one ends are fixed on the pedestal 15 by support 16, walk around fixed pulley 3, movable pulley 5, fixed pulley 2 successively, and the other end is wrapped on the capstan winch 7; Described sensor 14 is installed in the end of steel rope 4 near support 16, and connects with control box 13 by signal wire (SW) 20.
Described energy storage 8 is hermetically sealed stress metal tank body.
Described sensor 14 is the strain-type tension pick-up.
Described drop-gear box is a worm reduction box.
As Fig. 1, Fig. 2, shown in Figure 3, this device at first will be determined the stroke of tension of belt conveyor and the tensile force numerical value of adhesive tape starting tensile force and normal operation before using, the number of these two kinds of tensile forces is put be transported to control box 13.
Under automatic control mode, whether control system at first self check belt tension has fault.As detect normally, just the autonomous cruise speed system in the control box starts electric system, magnetic starter 11 closures, motor 9 drives capstan winches 7 rotations, and steel rope 4 spurs dolly 1 motion of moving about and makes belt tension.Sensor 14 is pounced on and is accomplished that electric control cabinet sent the signal that sealing-tape machine can start when steel rope 4 pulling force reached belt startup tensile force, and operation is also quickened in the sealing-tape machine starting.After sealing-tape machine reached constant speed row state, sensor 14 sent instruction, and 7 counter-rotatings of control box 13 control capstan winches make the pulling force of steel rope 4 be reduced to normal operation desirable value.In sealing-tape machine normal transport process, the sensor 14 of this device can be monitored the tensile force of belt automatically at any time.In case when finding that tensile force needs to change with operation, sensor 14 meeting output signals, the work of control box automatic guidance cushion cylinder 6, movable pulley 5 makes the stress of steel rope 4 be worth variation with the need with piston motion.Energy storage 8 mesohigh medium supply buffer oil cylinders 6 motion energy needed make the motion of cushion cylinder 6 absorb the of short duration tension fluctuation of operating belt, reduce belt fatigue.
Compression indicator 8-1 can observe the pressure of energy storage 8 medium, and when force value was put less than stated number, the pressurization that fuel primer pump is 12 pairs was to satisfy the energy demand of cushion cylinder 6.
Control system in this device also can be used operate in manual mode.
