Description
Technical field
The utility model designs hydraulic engineering field, especially designs a kind of Novel non-rising stem type screw rod headstock gear.
Background technique
In water supply and sewage work, gate is a kind of important device, and headstock gear is widely used in all kinds of large-scale plumbing, water
In sharp hydroelectric project, achieve the purpose that open and close gate by controlling the lifting of all kinds of gates.Screw open-close machine is because of it
It is low in cost and easy to operate and be widely used, but screw open-close machine in the prior art needs open up spiral shell on gate roof beam structure
The through-hole of bar disengaging opens up through-hole on one side gate roof beam structure and increases difficulty when casting is built, on the other hand needs to reserve screw rod
Space after back-out, higher to space requirement, screw rod is towering to be also not suitable with municipal landscape engineering to water engineering facility in overhead
Appearance requirement.Furthermore starting gate or when closed shutter in the prior art, requires to go above operator to gate roof beam structure
Headstock gear is operated, it is dangerous.
Utility model content
Purpose of utility model: the purpose of this utility model is that in view of the deficiencies of the prior art, providing a kind of novel dark bar
Formula screw rod headstock gear.
The innovative point of the utility model is for original screw-rod structure to be changed to the two-part of circular sleeve and screw rod cooperation
Structure, headstock gear drive circular sleeve rotation, and circular sleeve rotation drives screw rod rotation, and screw rod moves in circular sleeve always, nothing
Gate roof beam structure need to be screwed out；The utility model sets headstock gear to the switching mechanism of worm and gear, and operator is in lower section
Realize the open and close of gate, operational safety is high.
Technical solution: in order to reach above-mentioned purpose of utility model, the utility model is specifically achieved like this: Yi Zhongxin
Type blind rod type screw rod headstock gear includes doorframe, gate roof beam structure is equipped with above doorframe, and gate roof beam structure is equipped with headstock gear, door
Gate is installed in frame, is connected with screw rod above gate, further includes circular sleeve, be equipped in circular sleeve in screw rod cooperation
Screw thread, circular sleeve one end are connected with headstock gear, the other end and screw rod interference fit.The two-part of circular sleeve and screw rod cooperation
Structure, screw rod is towering in the overhead the technical issues of when not only solving starting gate in the prior art, and does not need in gate beam
On open up screw rod disengaging through-hole, reduce difficulty when casting.Since circular sleeve and screw rod are used in combination than being used alone
A piece spiro rod length wants short, and the requirement to processing equipment is low and convenient transportation；Internal screw thread and screw rod combination are set in circular sleeve to be made
It is stronger with intensity.Circular sleeve is connected with headstock gear, and Open Side Down also can avoid water or rubbish and enter circular sleeve for circular sleeve
It is interior.
Further, the headstock gear is worm and gear switching mechanism.
Further, the umbrella tooth gear roller box is made of two bevel gears, two umbellate form worm screws, respectively No.1 umbrella tooth
Wheel, No. two bevel gears, No.1 umbellate form worm screw, No. two umbellate form worm screws；Wherein No.1 bevel gear is fixedly connected with circular sleeve, No.1
Umbellate form worm screw is arranged horizontally in above gate roof beam structure, No.1 umbellate form worm screw one end and the cooperation of No.1 bevel gear, No.1 umbellate form worm screw
The other end stretches out outside doorframe and No. two umbellate form worm gears；No. two umbellate form worm screws are perpendicular to horizontal plane arrangement, No. two umbellate form worm screws
One end and No. two umbellate form worm gears, No. two umbellate form worm screw other ends are 1m-1.5m apart from ground level and handwheel are housed.Pass through
No. two umbellate form worm screw rotations are driven in terrestrial operation handwheel, No. two umbellate form worm screw rotations drive No. two umbellate form wheel rotations, No. two umbrellas
The rotation of type wheel drives the rotation of No.1 umbellate form worm screw, and the rotation of No.1 umbellate form worm screw drives the rotation of No.1 umbellate form wheel, No.1 umbellate form rotation
Dynamic to drive circular sleeve rotation, circular sleeve rotation drives screw rod rotation, the opening and closing of gate, operator can be realized
Safety ensured.
Further, the circular sleeve lower end is equipped with the Elastic Cylindrical strainer being socketed on circular sleeve, cylindrical
The diameter of elastic filter screen is greater than the diameter of circular sleeve and screw rod, and the length of Elastic Cylindrical strainer is greater than the length and packet of screw rod
It overlays on outside screw rod.Elastic Cylindrical strainer is coated on outside screw rod always according to the telescopic of screw rod turn, avoid water plant,
The rubbish such as polybag enter, and are stuck in the junction of screw rod and sleeve.
Further, several impellers are additionally provided in the circular sleeve lower sidewalls.Sleeve rotation, impeller turn
It is dynamic, reduce the water flow pressure of sleeve and screw rod junction, so that screw rod is easier to rotate, and wheel rotation makes rubbish separate
Sleeve and screw rod junction.
The utility model has the beneficial effects that the utility model has the advantages that compared with traditional technology
1, the two-part structure that circular sleeve and screw rod cooperate in the utility model, not only solves and opens in the prior art
Screw rod is towering in the overhead the technical issues of when gate, and does not need the through-hole that screw rod disengaging is opened up on gate beam, reduces casting
Difficulty when making.
2, the opening and closing of gate can be realized by operating handwheel on the ground in the utility model, operator's
Safety is ensured.
3, it is socketed Elastic Cylindrical strainer in circular sleeve lower end in the utility model, avoidable rubbish is caught in circular sleeve
With the junction of screw rod.
