Abstract

Bull stick formula gate hoist, it has motor, frame, screw rod and gate, and the screw rod is installed in the frame, and the output shaft and the screw rod of motor are connected with drive mechanism within a definite time, and the hookup has the nut on the gate, and screw rod and nut cooperation are fixed with the axle sleeve on the gate, and the nut is adorned in the axle sleeve, and the lateral surface of nut and the surface of axle sleeve hole are the sphere, and the hole clearance fit of the lateral surface of nut and axle sleeve, have multisection telescopic sleeve pipe at the outside cover of screw rod, the sheathed tube upper end is connected with the frame, sheathed tube lower extreme and the hookup of gate reel shaft cover. Owing to adopting the sphere cooperation between nut lateral surface and axle sleeve hole, when appearing following the small deflection of vertical direction in the gate reciprocates, can deflect relatively between nut and axle sleeve compensates, and nut and the friction between the screw rod avoiding causing because the gate deflects increase, the sheathed tube sets up, can avoid the winding of surface of water floater on the screw rod. The utility model discloses rational in infrastructure, compact, it operates steadily, the resistance is little, long service life.

Description

Rotating rod type gate hoist

Technical field

The utility model relates to the device that regulating gate opens and closes, specifically a kind of rotating rod type gate hoist.

Background technology

The places such as hydroelectric project, water supply and sewage work, urban flood defence projects for stagnant water drainage all widely use gate hoist.Substantially becoming of the worm-type open-close machine that existing a kind of regulating gate opens and closes: it has motor, frame, screw rod and gate, screw rod is arranged in frame, be connected with transmission mechanism between the output shaft of motor and screw rod, gate is connected with nut, screw rod and nut screw connection.At work, motor by transmission mechanism drive screw, makes nut to rise in the vertical direction together with gate by bolt rotary or declines this headstock gear.The main shortcoming that it exists is: due to the existence of installation deviation, gate has small deflection in upper and lower running, and this deflection can increase the friction between nut and screw rod, the aggravation rate of wear between the two; When floater is gathered near screw rod, the screw rod of rotation is very easily wound around floating thing, and the face that screws that floating thing gets into screw rod and nut can cause the resistance of bolt rotary to increase, and equipment can be caused time serious to run well or to shut down.

Utility model content

The purpose of this utility model is to provide a rotating rod type gate hoist, and this headstock gear will cause running resistance to increase because its gate occurs deflection at work, and the floating thing of the water surface can be prevented to be wound around by the screw rod rotated.

For achieving the above object, the utility model adopts following scheme: rotating rod type gate hoist, it has motor, frame, screw rod and gate, and screw rod is arranged in frame, is connected with transmission mechanism between the output shaft of motor and screw rod, gate is connected with nut, screw rod and nut screw connection, gate is fixed with axle sleeve, and nut is loaded in axle sleeve, the lateral surface of nut and the surface of inner hole of shaft sleeve are sphere, and the endoporus matched in clearance of the lateral surface of nut and axle sleeve; Have the sleeve pipe of Multi-section retractable in screw rod outer cover, the upper end of sleeve pipe is connected with frame, and the lower end of sleeve pipe connects with gate or axle sleeve.

From such scheme, motor by transmission mechanism drive screw, can make nut to rise in the vertical direction together with gate by the rotation of screw rod or decline.Owing to adopting mating spherical surfaces between nut lateral surface and inner hole of shaft sleeve, when gate moves up and down middle appearance small deflection vertically, nut relatively can deflect with shaft room and compensate, and avoids the friction due to gate deflection between the nut that causes and screw rod to increase with automatic deviation correction; In addition, the setting of sleeve pipe, can avoid floater to be wrapped on screw rod.

The utility model is rational in infrastructure, compact, and it operates steadily, resistance is little, long service life.

Fig. 4 is the B-B sectional view of Fig. 3.

Detailed description of the invention

The utility model is further illustrated below in conjunction with embodiment and accompanying drawing.

See Fig. 1, Fig. 2

The rotating rod type gate hoist that the utility model provides has motor 1, frame 5, screw rod 4 and gate 9, and screw rod 4 is arranged in frame 5, and be connected with transmission mechanism between the output shaft of motor 1 and screw rod 4, gate 9 is connected with nut 8, screw rod 4 coordinates with nut 8.Gate 9 is fixed with axle sleeve 7, and nut 8 is loaded in axle sleeve 7, and the lateral surface of nut 8 and the surface of axle sleeve 7 endoporus are sphere, and the endoporus matched in clearance of the lateral surface of nut 8 and axle sleeve 7.Have the sleeve pipe 6 of Multi-section retractable in screw rod 4 outer cover, the upper end of sleeve pipe 6 is connected with frame 5, and the lower end of sleeve pipe connects with axle sleeve 7.The floating thing of the water surface can stop by sleeve pipe 6, and when gate 9 rises or declines, sleeve pipe 6 is collapsible or stretch.Sleeve pipe 6 can be selected also can make specially from commercially available prod.

In the present embodiment, transmission mechanism has the driving bevel gear 2 and driven bevel pinion 3 that cooperatively interact, and motor 1 is reducing motor, and driving bevel gear 2 connects with the output shaft of motor 1, and driven bevel pinion 3 connects with screw rod 4, and the driving shaft of motor 1 is equipped with handle 10.

In addition, when nut rises to maximum height together with gate, for the floating thing preventing the screw rod position be in below nut to be wound around upper floating on water, in the present embodiment, enclosed cavity is adopted to protect to the screw rod that nut bottom is exposed, concrete mode is: the below being positioned at axle sleeve 7 on gate 9 is provided with the case 11 of tubulose, and the upper end of case 11 is connected with axle sleeve 7, and case 11 forms the enclosed cavity 11a entered for screw rod 4 below axle sleeve 7.

See Fig. 3, Fig. 4

This gives the another kind of structure of transmission mechanism, in the present embodiment, transmission mechanism has drive pulley 16, driven pulley 14, driving belt 15 and the worm gear 19 cooperatively interacted and worm screw 12, drive pulley 16 is loaded on the output shaft of motor 17, driven pulley 14 is loaded on worm screw 12, and driving belt 15 is loaded on drive pulley 16 and driven pulley 14, and screw rod 4 is arranged in frame 13, worm gear 19 connects with screw rod 4, at the two ends of worm screw 12, handle 18 is housed.Other parts in the present embodiment except said mechanism are all identical with embodiment one.

The effect that in above-described embodiment 1 and 2, handle is arranged is, when having a power failure or motor breaks down, by hand control handle, can realize the lifting of gate.
