The utility model discloses but the aperture information of gate is opened and close to accurate determination, demonstration, control headstock gear, realizes gate automatic control, and the dispatch benefit and the level of improve the engineering flood control, irrigating, generating electricity have realized the hydraulic engineering modern management, simultaneously, the utility model discloses still have advantages such as simple structure, action sensitivity, safe and reliable, convenient to use.
Description
Technical field:
The utility model relates to the headstock gear field lifting by crane water conservancy gate, particularly a kind of blind rod type screw open-close machine.
Background technology:
Headstock gear is widely used in all kinds of large-scale plumbing, Hydraulic and Hydro-Power Engineering, reaches to open and close the purpose of gate by controlling the lifting of all kinds of gates.It is divided into by type: hydraulic headstock gear, winch hoist, screw open-close machine etc..Wherein, screw open-close machine is widely used owing to it is convenient to operate and use cost is cheap.But general expression screw open-close machine screw rod is through the nut in the middle of headstock gear turbine seat, screw rod lower end is connected on the hanger of gate, drives gate opening/closing by the lifting of nut drive screw.Thus need to arrange the headstock gear that frame is high, enough spaces are left for opening liter gate, gate is in when closing door state, screw rod is exposed in the middle of support and gate, needs regular oiling to protect, after gate opening, screw rod is towering in the overhead of machine room, being easily bent and be struck by lightning, also impact is attractive in appearance especially, the inadaptable municipal administration landscape engineering appearance requirement to water engineering facility.
Utility model content:
The purpose of this utility model is a kind of blind rod type screw open-close machine provided to solve the deficiencies in the prior art.
The technical solution adopted in the utility model is:
Blind rod type screw open-close machine, including support, cabinet, the worm and gear assembly being arranged in cabinet, provide power motor, affixed with turbine together with screw rod, and with screw rod constitute threaded engagement hanger nut, it is characterised in that:
Described screw rod is connected as one with turbine by adapter sleeve, central principal axis, key, and screw rod, turbine, central principal axis are arranged concentrically；Described hanger nut is arranged on gate door top and fastens with gate with bolt.
Described blind rod type screw open-close machine, it is characterised in that:
Described cabinet is arranged above counting the journey controller of turbine rotating cycle and aperture encoder, and the rotatable parts of journey controller and aperture encoder are connected with central principal axis by shaft coupling and are arranged concentrically with turbine and central principal axis.
Described blind rod type screw open-close machine, it is characterised in that:
Being provided with scrubbing cutter head on described hanger nut, the blade of scrubbing cutter head embeds in screw flight groove.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is after using said structure, it is not necessary to setting up headstock gear, headstock gear can be directly mounted at above gate slot, drives screw rod to rotate by turbine and drives gate opening/closing；Screw rod is provided in below gate slot, gate is to followed by hanger nut to move up and down along screw rod, when gate hoists, screw rod stretches in the cavity offered inside gate, avoid common screw headstock gear screw rod towering in the overhead of machine room, the shortcoming solving impact the most inconvenient maintenance attractive in appearance, headstock gear occupation area of equipment is little, it is easy to hidden arrange, meets the requirement of municipal administration landscape engineering；By journey controller and altimeter coder, can accurately measure, show, control the opening information of headstock gear open-close sluice gate, realize Automatic controlling of strobe, improve engineering control flood, irrigate, the dispatch control benefit that generates electricity and level, achieve hydraulic engineering modern management, meanwhile, the utility model also have simple in construction, be active in one's movements, the advantage such as safe and reliable, easy to use.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the partial enlarged drawing in the utility model Fig. 1 at A.
Detailed description of the invention:
Below in conjunction with the accompanying drawings, by embodiment, the utility model is described in further detail:
A kind of blind rod type screw rod opens and closes, including support 1, cabinet 2, worm gear 3 worm screw 4 assembly being arranged in cabinet 2, provide power motor, affixed with turbine 3 together with screw rod 5, and constitute the hanger nut 6 of threaded engagement with screw rod 5；Headstock gear screw rod 5 is fixed together with turbine 3 by adapter sleeve 7, central principal axis 8, key, and screw rod 5, turbine 3, central principal axis 8 are arranged concentrically；Hanger nut 6 is arranged on 9, gate top, and fastens with gate 9 with bolt；Motor, after belt pulley, the secondary deceleration of turbine 3 worm screw 4, drives screw rod 5 to rotate, and hanger nut 6 drives gate 9 to move up and down along screw rod 5.
Cabinet 2 is arranged above counting journey controller 10 and the aperture encoder 11 of turbine rotating cycle, and the rotatable parts of journey controller 10 and aperture encoder 11 are connected with central principal axis 8 by shaft coupling, are arranged concentrically with turbine 3, central principal axis 8；By journey controller 10 and altimeter coder 11, can accurately measure, show, control the opening information of headstock gear open-close sluice gate 9, it is achieved gate 9 automatically controls.
Blind rod type screw open-close machine is provided with scrubbing cutter head 12 on hanger nut 6, and the blade of scrubbing cutter head 12 embeds in the thread groove of screw rod 5, for removing the dirts such as the weeds, the polybag that are wrapped on screw rod.
Above-described embodiment is only preferably embodiment of the present utility model, and in addition, the utility model can also have other implementations.It should be noted that on the premise of conceiving without departing from the utility model, within any conspicuously improved and modification all should fall into protection domain of the present utility model.
