Description
Technical field
The present invention relates to a kind of gate opening/closing system, more particularly to a kind of screw gates of segmental shape opening/closing system.
Background technology
Gates of segmental shape is the gate for the part arcwall face that obstructing surface is cylinder, and the supporting free bearing of its support arm is located at the center of circle,
Gate rotates around supporting free bearing during keying.Due to gates of segmental shape not gating groove, hoisting capacity is smaller, and HYDRODYNAMIC CONDITION RELATING TO is good, so extensively
It is general to be used to run as main gate on various types of water channels.Gates of segmental shape opening/closing system is by gates of segmental shape and opens and closes unit
Into gates of segmental shape is generally mounted to the lower of sill may, and headstock gear is installed on the eminence of sill may, and headstock gear is used to open and close arc
Shape gate.
In existing gates of segmental shape opening/closing system, headstock gear uses winding type arc door headstock gear more, passes through band by motor
The shaft coupling and decelerator of braked wheel, open gear pair and cable drum is driven to rotate, and cable drum is further through steel wire
Rope couples with the hanger of gates of segmental shape, realizes the keying requirement of gates of segmental shape.But because winding type arc door headstock gear drives
The transmission of device is bigger, and steel wire rope is relatively large in diameter, therefore whole headstock gear size is larger.Profile is big, from great, space-consuming
Greatly, it is not easy to installation, cost height is the shortcomings that existing winding type arc door headstock gear is obvious.

Line, the worm screw at the turbine center are provided with screw thread, and the worm screw engages connection with the outer circumferential walls of the nut.Above-mentioned worm screw
It is mutually perpendicular to located at the center of turbine and with the side surface of turbine, worm screw and turbine synchronous rotary.
Further, the headstock gear also includes the shell being fixedly installed on the active mount, the nut installation
In in the shell, being provided with ball between the nut and the shell to realize that the nut revolves relative to the shell
Turn, the worm screw with the outer circumferential walls of the nut through engaging connection after the through hole on the shell.
For ease of installation, the fixed mounting is two, and the both ends of the active mount pass through two rotating shafts respectively
It is corresponding with two fixed mountings to connect, opening of the screw rod through two fixed mountings.
Specifically, the top of the fixed mounting is provided with through hole, and the line between two fixed mountings is same
The rotating shaft of axial direction passes through the through hole of the fixed mounting.
In order to prevent screw rod from departing from nut, the upper end of the screw rod, which is provided with, to be used to prevent the screw rod from departing from the nut
Limited block.
The beneficial effects of the present invention are：
Screw gates of segmental shape opening/closing system of the present invention uses screw rod to drive gates of segmental shape rotation to be opened and closed to realize, contracting
The small appearance and size of headstock gear, it is compact-sized, save the confined space of hoist chamber；This screw gates of segmental shape opens and closes system
/ 5th or so of the only traditional winding type arc door headstock gear of the headstock gear quality of system, significantly reduce manufacturing cost, and be easy to
Care and maintenance, can wide popularization and application in various rivers break-make control.
