Description
Technical field
The utility model is related to headstock gear technical field, especially a kind of screw open-close machine screw rod protective device.
Background technology
Worm-type open-close machine have the characteristics that it is simple in structure, using reasonable, cheap, easy for installation, A wide selection of colours and designs quilt
It is widely used in various hydraulic engineerings.But worm-type open-close machine also has deficiency in actual use：Screw rod protects bad, screw thread
It is easily destroyed, reduces transmission efficiency or even failure.After gate opening, screw rod is towering in the overhead of computer room, be easily bent and by
Lightning stroke, and exposure easily causes corrosion in air.
Utility model content
In order to overcome the shortcomings of that existing screw open-close machine screw flight is easy to wear, the easy corrosion of screw flight, this reality
A kind of screw open-close machine screw rod protective device is provided with new, screw rod is inserted in wherein and is fixed on headstock gear by screw rod protective sleeve
Main body upper end during use, can observe the screw position in screw rod protective sleeve observation cover board opening.
Technical solution is used by the utility model solves its technical problem：A kind of screw open-close machine screw rod protection dress
It puts, including headstock gear main body, screw rod and gate, screw rod protective sleeve is fixedly connected in headstock gear main body, screw rod protective sleeve includes
Firm banking, pedestal top are fixedly connected with screw rod protective sleeve shell, and screw rod protective sleeve shell side is equipped with observation cover board.
Further, it is equipped with to wear the groove of screw rod including screw rod protective sleeve inner cavity.
Further, the maximum height on top is risen to more than screw rod including hollow groove height.
Further, it is equipped with to agree with the observation panel for observing cover board including screw rod protective sleeve shell.
Further, it is connected through the hinge including observation cover board in observation panel side.
The beneficial effects of the utility model are a kind of screw open-close machine screw rod protective devices of the utility model, and screw rod is protected
Screw flight is caused to wear and damaged by physical shock to it when sheath avoids use, and screw rod is also prevented to be exposed to air
It is middle by corrosion the problem of, during use, can will observation cover board opening the screw position in screw rod protective sleeve is seen
It examines, provides gate operation reference to operating personnel so as to more convenient, ensure that the normal operation of gate.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the sectional view of Fig. 1；
Fig. 3 is the partial enlarged view at A in Fig. 2.
1. headstock gear main body in figure, 2. screw rods, 3. gates, 4. screw rod protective sleeves, 5. firm bankings, outside 6. screw rod protective sleeves
Shell, 7. observation cover boards, 8. grooves, 9. observation panels, 10. hinges.
Specific embodiment
If Fig. 1 is the structure diagram of the utility model, a kind of screw open-close machine screw rod protective device, including opening and closing owner
Body 1, screw rod 2 and gate 3 are fixedly connected with screw rod protective sleeve 4 in headstock gear main body 1, and screw rod protective sleeve 4 includes firm banking 5,
5 top of firm banking is fixedly connected with screw rod protective sleeve shell 6, and 6 side of screw rod protective sleeve shell is equipped with observation cover board 7.
Screw rod 2 is inserted in wherein and is fixed on 1 upper end of headstock gear main body by screw rod protective sleeve 4,2 spiral shell of screw rod when avoiding use
Line is caused to wear and damaged by physical shock to it, the problem of screw rod 2 is also prevented to expose in air by corrosion, is being used
During, observation cover board 7 can be opened and 2 position of screw rod in screw rod protective sleeve 4 is observed, so as to more convenient
Give operating personnel provide gate 3 run reference, ensure that the normal operation of gate 3.
5 inner cavity of screw rod protective sleeve is equipped with to wear the groove 8 of screw rod 2, and 8 height of groove rises to more than screw rod 2
Screw rod protective sleeve 5 is fixed in headstock gear main body 1 by the maximum height on top, is played a protective role to the screw rod 2 of rising, is
The rising of screw rod 2 is avoided to strike screw rod protective sleeve 4, and then the depth capacity of groove 8 is controlled and rises limit height in screw rod 2
On degree.
Screw rod protective sleeve shell 6 is equipped with to agree with the observation panel 9 of observation cover board 7, and observation cover board 7 is connected by hinge 10
9 side of observation panel is connected on, when running headstock gear main body 1, screw rod 2 can raising and lowering, observer must pass through screw rod 2 therewith
The position risen or fallen judges the position of gate 3, and then is accurately positioned gate height, which passes through observation
Cover board 7 can play the role of sealing screw rod protective sleeve 4, while can also open it and be seen by observation panel 9 when in use
Examine the position of screw rod 2.
It is described above to be merely exemplary for the utility model, and not restrictive, those of ordinary skill in the art
Understand, in the case where not departing from spirit and scope as defined in the appended claims, many modifications can be made, change or wait
Effect, but fall in the scope of protection of the utility model.
