Description of drawings
Fig. 1 is the utility model integral structure scheme drawing.
The specific embodiment
Below embodiment of the present utility model is elaborated; present embodiment is being to implement under the prerequisite with technical solutions of the utility model; provided detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
Referring to Fig. 1, the belt conveyer Hydranlic tensioner that the utility model provides, comprise fuel tank 14 and the hydraulic oil pump 1 that links to each other with fuel tank 14, hydraulic oil pump 1 is connected with motor 2, hydraulic oil pump 1 outlet connects filter 3 successively, check valve 4 entrances, check valve 4 exits connect first by pass valve, 5 entrances and 3-position 4-way solenoid directional control valve 6 entrances respectively, 5 outlets of first by pass valve all link to each other with fuel tank 14 with 3-position 4-way solenoid directional control valve 6 another entrances, 6 outlets of 3-position 4-way solenoid directional control valve are divided into two-way, one the tunnel through hydraulic control one-way valve 7 respectively with tensioning hydro-cylinder 8 ante-chambers, pressure controller 9, compression indicator 10, two energy storages 11 and 12 outlets of 2/2-way solenoid directional control valve connect, 2/2-way solenoid directional control valve 12 entrances link to each other with second by pass valve, 13 entrances, 13 outlets of second by pass valve link to each other with fuel tank 14, and 3-position 4-way solenoid directional control valve 6 another roads of outlet link to each other with tensioning hydro-cylinder 8 back cavities and hydraulic control one-way valve 7 control ports.
Hydraulic oil pump 1 makes tensioning hydro-cylinder 8 motions carry out tensioning by external motor 2.When belt conveyer starts, needed tensile force is bigger, the electromagnet of 2/2-way solenoid directional control valve 12 must not at this moment, the tensile force of tensioning hydro-cylinder 8 is by 5 controls of first by pass valve, the pressure set points of first by pass valve 5 is bigger, and therefore can satisfy belt conveyer starts the bigger requirement of required tensile force.
After belt conveyer is finished startup, needed tensile force is less, the electromagnet of 2/2-way solenoid directional control valve 12 gets at this moment, the tensile force of tensioning hydro-cylinder 8 is by 13 controls of second by pass valve, the pressure set points of second by pass valve 13 is less, the less requirement of required tensile force in the time of therefore can satisfying belt conveyer work.
Hydraulic control one-way valve 7 in the device plays the effect of locking tensioning hydro-cylinder 8, can be in certain position long-term work with the piston rod that guarantees tensioning hydro-cylinder 8, because hydraulic efficiency pressure system has leakage reasons, energy storage 11 plays the effect of revealing fluid in the replenishment system.In addition, the energy storage 11 in the device can also absorb impact load, plays the effect of buffering.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
