Abstract
The utility model discloses a friction drive compression device, which is capable of automatically adjusting compression force and fine in use effect. The friction drive compression device comprises a compression mechanism connected with a drive swing arm; the compression mechanism includes a cylinder consisting of a cylinder body and a piston rod; the end of the piston rod is connected with the drive swing arm; a gas input cavity of the cylinder is connected with an output end of a precision pressure reducing valve; and an input end of the precision pressure reducing valve is connected with an output end of a filter pressure reducing valve. The friction drive compression device is applicable to friction conveyors.
Description
Technical field
The utility model relates to a kind of load transfer device, relates in particular to the driving pinch device on a kind of conveyer that is used to rub.
Background technology
Pinch device in the tradition friction drive device adopts spring device, because the friction travel line is continuous conveying, the pinch device perseveration, will inevitably cause problems such as spring fatigue inefficacy, under the effect of long-term cyclic loading, the workload of spring descends, produce stress relaxation phenomenon, and when the car group moves to ramp or bend, because required propulsive effort changes at any time, and adopt spring device can't realize accurately regulating automatically, thereby phenomenons such as car or car group jam may occur slipping, thereby cause system's operation not steadily or the generation accident.
The utility model content
But the technical problems to be solved in the utility model provides a kind of automatically regulating and compresses dynamics, friction-driven pinch device that result of use is good.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises and drives the hold-down mechanism that swing arm is connected, described hold-down mechanism comprises cylinder, described cylinder is made up of cylinder body and piston rod, described piston rod end is connected with the driving swing arm, described cylinder gas input cavity is connected with the mouth of accurate reducing valve, and the input end of described accurate reducing valve is connected with the mouth of filtering pressure reducing valve.
Because the hold-down mechanism in the utility model adopts cylinder, and the cylinder gas input cavity is connected with the mouth of accurate reducing valve, not only can keep the constant of cylinder thrust, but automatically regulating compresses dynamics, adapting to the variation of ramp or bend propulsive effort, thereby improve system's operation stability.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and the specific embodiments the utility model is described in further detail:
As shown in drawings: the utility model comprises and drives the hold-down mechanism that swing arm 1 is connected, hold-down mechanism comprises cylinder, cylinder is made up of cylinder body 2 and piston rod 3, piston rod 3 ends are connected with driving swing arm 1, the cylinder gas input cavity is connected with the mouth of accurate reducing valve 5, and the input end of accurate reducing valve 5 is connected with the mouth of filtering pressure reducing valve 6.
The utility model principle of work is: mainly utilize accurate reducing valve delivery pressure to keep constant characteristic, utilize constant air pressure to keep the constant of cylinder thrust.When load during greater than cylinder thrust, piston rod 3 withdrawals, gas in the jar is discharged by the exhausr port of accurate reducing valve 5, but cylinder thrust still remains unchanged; When load reduces, when being lower than cylinder thrust, piston rod 3 rises, and inner pressure of air cylinder reduces, and at this moment, accurate reducing valve 5 is opened rapidly, inflates in cylinder, guarantees the cylinder constant propulsion.The effect of filtering pressure reducing valve 6 is to make inlet pressurized air cleaning, and the preliminarily stabilised gaseous tension.The utility model can according to around operating mode and transmit attribute (delivery speed, ambient temperature and transmit material, period of service etc.) information automatically regulating and compress dynamics.
