Specific embodiment
A kind of hydraulic automatic tensioning device, as shown in the figure：Including device for monitoring tension 5, device for monitoring tension 5 is by fixed mount
6th, back-moving spring 7, fixed mount sleeve 8, pulling force sensor a9 and pulling force sensor b10 composition, the wherein two ends of tension drum 4 are stretched
Shaft is limited in the elongated hole of fixed mount 6, there is certain up and down scope, and the lower end of fixed mount 6 is limited in fixed mount sleeve 8, Gu
Determining frame 6 can be up and down, and the lower end of fixed mount sleeve 8 is connected by bolt with ground, wherein the one end of back-moving spring 7 and fixed mount 6
It is connected, the other end of back-moving spring 7 is connected with pulling force sensor a9 one end, the pulling force sensor a9 other ends pass through steel wire rope and pulling force
Sensor b10 one end is connected, and the pulling force sensor b10 other ends are connected by steel wire rope with ground.Device for monitoring tension 5 is located at down
At conveyer belt tension drum 4, two bend pulleys 3 change the rotation directions of conveyer belt 1, by tension drum 4 by conveyer skin
Band 1 is tensed, and back-moving spring 7 is indirect to the certain pulling force of tension drum 4 by fixed mount 6 in tensing monitoring device 5, and by pulling force
Value of thrust suffered by conveyer belt 1 is passed to controller by sensor a9, pulling force sensor b10, and controller is according to pulling force
The signal that sensor is transmitted is controlled to Oil pump electrical machinery.Conveyer drive roll 2 is fixed on tension dolly 11, small to tensing
