Abstract
The invention discloses a motor-driven threaded rod starting and stopping machine relating to the field of the structure of a gate starting and stoping device. The motor-driven threaded rod starting and stopping machine comprises a screw mechanism and a threaded rod, wherein the screw mechanism comprises an extending spindle. The starting and stopping machine also comprises a first bracket fixedly connected with a cement concrete beam, wherein the outer side of the first bracket is fixedly connected with a second bracket; the second bracket is connected with a pin gear speed reducer; one end of the pin gear speed reducer is connected with a motor; and the other end of the pin gear speed reducer is connected with the extending spindle of the screw mechanism by a coupler. Only a button for controlling ascending or descending needs to be started when the machine works, the motor rotates to drive the pin gear speed reducer to rotate; the screw mechanism is driven by the coupler to rotate so as to drive the threaded rod to carry out linear motion, thereby driving a gate on the lower end of the threaded rod to ascend or descend; and when the gate is opened or closed to the proper position, the gate contacts with a lead limit switch, and the power of the motor is automatically cut off, thus the gate stops moving. The motor-driven threaded rod starting and stopping machine has the advantages of high precision, stable performance and the like, is flexible to start and stop, is convenient to operate and only needs to be controlled by one person on the bottom of the gate.
Description
Technical field
The present invention relates to the structure field of gate hoist.
Background technology
Worm-type open-close machine is applied to the hydraulic gate of various large, medium and small water conservancies, water station and municipal engineering, existing worm-type open-close machine is a hand screw formula headstock gear, driving screw rod by screw mechanism moves up and down, the lifting of traction gate, there are defectives such as labour intensity is big, work high above the ground, maintenance inconvenience in hand screw formula headstock gear.
Summary of the invention
The objective of the invention is in order to overcome the deficiencies in the prior art, provide that a kind of labour intensity is low, control accuracy is high, keying is flexible, the electric screw headstock gear of stable performance.
The object of the present invention is achieved like this: the electric screw headstock gear, comprise screw mechanism and screw rod, screw mechanism comprises and stretches out rotating shaft, described headstock gear also comprises first support that can fixedly connected with the cement concrete crossbeam, fixedly connected second support in the outside of first support, connect cycloidal planetary gear speed reducer on second support, an end of cycloidal planetary gear speed reducer connects motor, and the other end of cycloidal planetary gear speed reducer connects the rotating shaft of stretching out of described screw mechanism by shaft coupling.
Only need start during work and rise or the decline button, the rotation of motor rotating band dynamic cycloid pin gear speed reducer drives the screw mechanism rotation by shaft coupling and drives the screw rod rectilinear motion, screw rod rises or descends, thereby the gate that drives the screw rod lower end rises or descends, touch the lead limit switch motor when putting in place and cut off the power supply automatically when gate reaches the position or closes, gate is slack.The present invention has the control accuracy height, opens and closes flexible, stable performance, easy to operate, only needs a people in advantages such as gate bottom controls.
In order to prevent that motor and cycloidal planetary gear speed reducer from being drenched with rain, also connect protective cover on described second support, described motor and cycloidal planetary gear speed reducer are separately positioned in the protective cover.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 be among Fig. 1 B to view.
Among the figure, 1 protective cover, 2 motors, 3 cycloidal planetary gear speed reducers, 4 shaft couplings, 5 second supports, 6 first supports, 7 screw arbor assemblies, 8 screw mechanisms, 8-1 stretches out rotating shaft, 9 screw rods, 10 crossbeams.
The specific embodiment
As shown in Figure 1, 2, be the electric screw headstock gear, comprise screw mechanism 8 and screw rod 9, screw mechanism 8 comprises and stretches out rotating shaft 8-1, screw mechanism 8 is installed in the top of cement concrete crossbeam 10, the lower end of screw rod 9 connects gate, crossbeam 10 is outer by screw arbor assembly 7 connections first support 6, second support 5 is welded in the outside of first support 6, connect cycloidal planetary gear speed reducer 3 on second support 5, one end of cycloidal planetary gear speed reducer 3 connects motor 2, and the other end of cycloidal planetary gear speed reducer 3 stretches out rotating shaft 8-1 by what shaft coupling 4 connected screw mechanisms 8.Also connect protective cover 1 by bolt on second support 5, motor 2 and cycloidal planetary gear speed reducer 3 are separately positioned in the protective cover 1.
Claims (2)
