The utility model provides a digitized screw-type open-close machine made up of an open-close machine body, an open-close screw, an electric motor, a worm, a turbine, a driven turbine, a connecting shaft, a drive gear, a transmission gear, an encoder, and a limiting stopper, wherein, the driven turbine is connected to the worm connected with the electric motor, the driven turbine is connected withthe drive gear through the connecting shaft, the drive gear is meshed with the transmission gear, the transmission gear is connected with the encoder, and the limiting stopper is connected with the connecting rod positioned on the open-close machine body and provided with a chamber with an embedded bearing connected therein. The utility model can effectively avoid the occurrence of incidents suchas overloading of the open-close machine and bending of the screw, has the advantages of long operation period, low cost in maintenance and operation, safe and stable performance, convenient use andthe like, and is suitable for various waterlocks and ship locks used in water conservancy projects as well as gate valves used in other projects.

Description

The digitizing worm-type open-close machine

Technical field

The utility model relates to the machinery that a kind of regulating gate opens and closes.

Background technique

Along with growing and scientific and technical the advancing by leaps and bounds of water conservancy, the technical requirements of the gate valve of extensive use being controlled open/close machinery is also more and more higher.In known technology, the gate valve open/close machinery mainly is made up of the driving mechanism that hoist fuselage, keying screw rod and turbine and worm are formed, limit by its structure, when being used for occasion such as sluice, ship lock, in case meet overload, opening and closing load can not limit, can cause hoist overload and screw rod press-bending accident, influence normal operation, the hoist life cycle shortens, and maintenance and operating cost are too high.In addition,, and can not realize controlling automatically the keying of gate valve, and drive motor running as usual may cause major accident, brings bigger loss if this fault message can not in time pass to control system.

Summary of the invention

The utility model is used to overcome the deficiency of prior art, provides a kind of hoist of effectively avoiding to overload and screw rod press-bending accident, and is suitable for carrying out the digitizing worm-type open-close machine of gatage and the automatic control of limit position.

Addressing the above problem the technological scheme that is adopted is:

A kind of digitizing worm-type open-close machine, be provided with the hoist fuselage in the formation, open and close screw rod, motor, worm screw, turbine, driven turbine, connecting shaft, driving gear, driving gear, encoder, snubber, connect driven turbine on the worm screw that motor connects, driven turbine connects driving gear by connecting shaft, driving gear engagement driving gear, driving gear connects encoder, and snubber is installed in the connecting shaft that is connected by the bearing of inlaying in the hoist fuselage epicoele.

Above-mentioned digitizing worm-type open-close machine, described worm screw also connects the bent axle by the bearing load, and bent axle connects torque sensor by the sensor stand of load on the hoist fuselage, and torque sensor also connects snubber.

Above-mentioned digitizing worm-type open-close machine, described encoder are preferably used GB64-32768/640-GN-12-24 type photoelectric absolute encoder, or adopt other suitable type encoder.

The utility model is fitted on the predetermined gate valve, and according to action need, after the encoder setting, just can requiring automatically according to programming, the keying of control gate valve moves.Be in operation, in case when overload and excessive torque occur occurring, this function is transshipped the resolution process and the transmission of torsion automatically, thereby avoids causing mechanical failure and economic loss.

Because technique scheme has been adopted in the utility model design, it is unreasonable to have solved existing worm-type open-close machine structural design effectively, can not decompose and carry-over moment when meeting overload, causes the short problem of mechanical life cycle.And, it can cooperate, realize that the digitizing of gatage and limit position controls automatically at an easy rate with control circuit, avoid the generation of hoist overload and screw rod press-bending accident effectively, it is long to have an operation period, the maintenance operation expense is low, the performance safety and stability, advantage such as easy to use is applicable to the gate valve in various sluice in the hydraulic engineering, ship lock and other engineering.
