Abstract
Speed closes machine buffer, is related to gate control mechanism.A kind of delicate structure, stable performance are provided, the speed of reliable in action closes machine buffer.Including casing assembly, gear drive and screw mandrel, the gear drive is located in casing assembly, and the gear drive drives screw mandrel lifting action, top connection buffer, the bottom connection gate of the screw mandrel；The buffer includes piston rod, piston and cylinder barrel, and one end of the piston rod is fixedly connected with screw mandrel, other end connection piston, and the piston rod stretches into cylinder barrel, and the piston is located in cylinder barrel, and the cylinder barrel is located at the top of casing assembly.Buffer pulls cylinder barrel inner carrier by piston rod, changes in the past by method in place of conducting oneself with dignity, acts more stable reliable.When screw mandrel rises, cylinder barrel and piston rise action, extension spring is set so that cylinder barrel downward actuation, now, piston are located at the top of cylinder barrel, when being easy to the screw mandrel to decline, play reliable action of giving.
Description
Technical field
Gate control mechanism is the utility model is related to, more particularly to a kind of speed closes machine buffer.
Background technology
Common gate and headstock gear is generally used in the water process such as pipe network or the pumping plant of water treatment plant or hydraulic engineering
On structures, the circulation of current is controlled.Although general in engineering all designed using dual power supply, in actual use, double
The corresponding time of power supply can not meet security needs.In order to prevent water impact, the generation of accident such as pour in down a chimney, at present at these
Critical critical point, speed typically can be all installed and close headstock gear, in order in the case of power failure or manual operation, cut off water rapidly
Stream, ensure subsequent technique, equipment and the safety of personnel.At present, in the prior art, speed closes machine when closed, real by spring
Now buffer, its reliability is low, and stability is poor, potential safety hazard be present.
Utility model content
The utility model is directed to problem above, there is provided a kind of delicate structure, stable performance, the speed of reliable in action close machine use
Buffer.
The technical solution of the utility model is：Speed, which closes machine, includes casing assembly, gear drive and screw mandrel, the gear
Transmission mechanism is located in casing assembly, and the gear drive drives screw mandrel lifting action, and the top connection of the screw mandrel is delayed
Rush device, bottom connection gate；
The buffer includes piston rod, piston and cylinder barrel, and one end of the piston rod is fixedly connected with screw mandrel, and the other end connects
Take over a job plug, the piston rod stretches into cylinder barrel, and the piston is located in cylinder barrel, and the cylinder barrel is located at the top of casing assembly.
Also include dust cover, the dust cover is connected between casing assembly and cylinder barrel, and the piston rod is located at dust cover
It is interior.
Also include extension spring, the extension spring connects cylinder barrel and casing assembly respectively.
The gear drive includes main roller gear, from roller gear and screw mandrel screw pair, the main roller gear
It is meshed with from roller gear, the screw mandrel screw pair is located at out of roller gear, and the screw mandrel screw pair includes feed screw nut,
The feed screw nut fixes and is located at out of roller gear, and the screw mandrel is located in feed screw nut.
At work, buffer pulls cylinder barrel inner carrier to the utility model by piston rod, changes in place by conducting oneself with dignity in the past
Method, act more stable reliable.When screw mandrel rises, cylinder barrel and piston rise action, extension spring is set so that cylinder barrel moves downwards
Make, now, piston is located at the top of cylinder barrel, when being easy to the screw mandrel to decline, plays reliable action of giving.The utility model structure is closed
Reason, stable performance are easy to operate.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
5 be casing assembly in figure,
6 be gear drive, and 61 be main roller gear, and 62 be from roller gear, and 63 be screw mandrel screw pair, and 631 be silk
Stem nut,
7 be screw mandrel,
8 be buffer, and 81 be piston rod, and 82 be piston, and 83 be cylinder barrel, and 84 be exhaust cap, and 85 be dust cover, and 86 be to draw
Spring.
Embodiment
The utility model includes casing assembly 5, gear drive 6 and screw mandrel 7, the gear as shown in figure 1, speed closes machine
Transmission mechanism 6 is located in casing assembly 5, and the gear drive 6 drives the lifting action of screw mandrel 7, connects at the top of the screw mandrel
Connect buffer 8, bottom connection gate；
The buffer 8 includes piston rod 81, piston 82 and cylinder barrel 83, and one end of the piston rod 81 is fixedly connected with screw mandrel
632, other end connection piston 81, the piston rod 81 stretches into cylinder barrel, and the piston is located in cylinder barrel, and the cylinder barrel 83 is located at case
The top of body assembly.
Buffer is located at the upper end of leading screw, and after gate is lifted in place, piston rod should be at stretching state, otherwise should be at
Compressive state, traditional buffer realize stretching state by deadweight, often performance less stable, and the utility model, which is carried out, to be forced to draw
It is pulled to position.In work, piston is provided with exhaust cap 84.
Also include dust cover 85, the dust cover 85 is connected between casing assembly and cylinder barrel, and the piston rod 81 is located at
In dust cover；Play dustproof effect.
Also including extension spring 86, the extension spring 86 connects cylinder barrel 83 and casing assembly 13, plays the effect reliably pulled respectively,
Meanwhile avoid because range error produces hard draw phenomenon, having stable behavior is reliable, effectively solves by the unstable phenomenon of gravity reduction.
When screw mandrel rises, cylinder barrel and piston rise action, extension spring is set so that cylinder barrel downward actuation, now, piston position
In the top of cylinder barrel, when being easy to the screw mandrel to decline, reliable action of giving is played.
The gear drive 6 includes main roller gear 61, from roller gear 62 and screw mandrel screw pair 63, the screw mandrel
Screw pair 63 is located at out of roller gear 62, the main roller gear 61 and is meshed from roller gear 62, the screw mandrel spiral
Pair 63 includes feed screw nut 631, and the feed screw nut 631 fixes and is located at out of roller gear 62, and the screw mandrel 7 is located at screw mandrel spiral shell
In mother 631.In work, main roller gear drives from roller gear and acted, and the feed screw nut out of roller gear drives screw mandrel liter
Drop acts；Meanwhile can be by motor-driven rotatable shaft, rotating shaft drives main roller gear action.
