Description
Technical field
It the utility model is related to a kind of headstock gear, more particularly to a kind of side-mounted screw open-close machine.
Background technology
Headstock gear is typically used in all kinds of large-scale plumbing and Hydraulic and Hydro-Power Engineering, for controlling all kinds of large and medium-sized castings
The lifting of iron gate and steel gate reaches the purpose of open and close.It is required when traditional headstock gear is typically according to gate opening/closing
Operation torque selectes model, and corresponding screw diameter is selected further according to headstock gear model.Sometimes due to gate installation aperture is extremely
Open and close that machine platform is deeper, it is also contemplated that when headstock gear is closed screw rod pressure bar stabilization, cannot the routinely supporting spiral shell of headstock gear
Bar, diameter is less than normal, is easily bent in real work, and during the actual type selecting of headstock gear, screw diameter is greater than conventional supporting headstock gear
It is required that diameter, sometimes require that big more.It is straight by screw diameter greatest limit that electric device corresponds to model installation dimension endoporus
Footpath often can not meet requirement.Need to increase model, can be by causing the wasting of resources.
Utility model content
For drawbacks described above, the purpose of this utility model be to provide it is a kind of simple in construction, it is easy for installation, worn without screw rod
Electric device endoporus is crossed, operation torque can either be met, and can is enough according to situation adjusting bolt diameter, avoids bent screws, makes
With a kind of side-mounted screw open-close machine of long lifespan.
Technical scheme is used by for this utility model：
Including support, the pedestal upper end is provided with gear-box, is provided with screw rod in the support, the screw rod runs through support
And gear-box, the gear-box is interior to be provided with the drive sleeve being socketed in outside screw rod, and the outer upper end of the drive sleeve is cased with driven wheel of differential,
The gear-box side wall is provided with bearing hole, is provided with power transmission shaft in the bearing hole, the inner of the power transmission shaft be provided with
The driving bevel gear that driven wheel of differential is engaged, the driving bevel gear are located in gear-box, and the gear-box side is provided with electricity
Dynamic device, the output end of the electric device is socketed by the outer end of paul pawl coupling and power transmission shaft to be connected.
As the further improvement of above-mentioned technical proposal, the lower end of the electric device is provided with support frame.
As the further improvement of above-mentioned technical proposal, the middle part external diameter of the power transmission shaft is provided with boss, the boss
Both sides are respectively equipped with the bearing I in bearing hole.
As the further improvement of above-mentioned technical proposal, the bearing being located in gear-box is cased with outside the lower end of the drive sleeve
II。
The utility model has the advantages that：
The utility model is simple in construction, and installation operation is convenient, by the way that electric device is arranged on into screw rod side, and passes through cone
The moment of torsion of electric device is passed to screw rod by gear, and electric device is passed through without screw rod, can meet operation torque, and can according to
Situation selects screw diameter, effectively avoids bent screws, increases the service life.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
