Description
Technical field
The utility model is related to a kind of elevator, specifically a kind of dust-proof stroke automatic control worm and gear elevator.
Background technology
Worm gear feed screw elevator is widely used in the equipment or instrument that all kinds of needs move up and down, currently, domestic snail
It takes turns screw lift using worm and gear to slow down, so that lead screw is stretched by the trapezoidal thread transmission between worm gear and lead screw
Contracting movement achives up and down.But since trapezoidal thread transmission is there are axial gap, transmission accuracy is not high when elevator duty,
Lifting position cannot accurately control, while lead screw lifting is exposed outside, and dust, which easily enters, influences Worm Wheel System in speed reducer.
Invention content
Against the above deficiency, the utility model provides a kind of simple in structure, can effectively control lifting and be formed, prevent dust
Into the dust-proof stroke automatic control worm and gear elevator for influencing lifting work.
The technical solution adopted in the utility model is：A kind of dust-proof stroke automatic control worm and gear elevator, it is characterised in that：
Including babinet, elevating screw, limit lifting babinet, anti-rotation sliding block, plate, travel switch, driving worm gear, driving snail is mounted
Bar, telescopic sleeve, elevating screw are connected on babinet up and down, and elevating screw stretches into the limit lifting being connected to below babinet downward
In babinet and its bottom connection anti-rotation sliding block, the external side of limit elevator chamber, which is equipped with, is mounted plate, and plate is mounted equipped with upper
Lower adjustable upper and lower two travel switches of relative position, anti-rotation sliding block be correspondingly arranged between upper and lower two travel switches in
It is in limit state that elevating screw, which lifts correspondence course switch, and elevating screw is worn on the driving worm gear being connected in succession in babinet, is driven
Worm screw level, which is worn, is connected on babinet and engages driving worm gear, and elevating screw stretches out babinet upward and telescopic sleeve sealing is socketed on and stretches
Go out part, it is described that the displacement sensor that corresponding position limiting slide block is additionally provided on plate is mounted.
The telescopic sleeve lower end is connected on babinet, and upper end is connected to elevating screw top or top.
The utility model will lift the telescopic sleeve that lower part is placed in limit elevator chamber body, top suit tunnel is flexible, energy
It effectively prevent dust to enter influence Worm Wheel System by babinet top or lower part, while preventing lifting super using travel switch
Limit measures monitoring feedback in real time in conjunction with displacement sensor monitoring elevating screw lifting, and overall operation automatic controlling level is high, makes
With excellent performance, safety, long lifespan.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
In figure：Elevating screw 2, limit lifting babinet 3, anti-rotation sliding block 4, plate 5, travel switch 6, position is mounted in babinet 1
Displacement sensor 7, driving worm gear 8, driving worm screw 9, telescopic sleeve 10.
Specific implementation mode
It is described further below in conjunction with attached drawing.
Shown in Fig. 1：A kind of dust-proof stroke automatic control worm and gear elevator includes babinet 1, elevating screw 2, limit elevator chamber
Plate 5, travel switch 6, displacement sensor 7, driving worm gear 8, driving worm screw 9, telescopic sleeve is mounted in body 3, anti-rotation sliding block 4
10.About 2 elevating screw is connected on babinet 1, and elevating screw is stretched into downward in 3 body of limit elevator chamber being connected to below babinet
And its bottom connection anti-rotation sliding block 4,3 external side of limit elevator chamber, which is equipped with, is mounted plate 5, and plate is mounted and is equipped with phase up and down
Upper and lower two travel switches 6 adjustable to position and displacement sensor 7, anti-rotation sliding block 4 are correspondingly arranged in upper and lower two strokes
It is switched in limit state in elevating screw lifting correspondence course between switch, while also corresponding to displacement sensor 7, lifting silk, 2
It wears on the driving worm gear 8 being connected in succession in babinet, driving 9 level of worm screw, which is worn, is connected on babinet and engages driving worm gear 8, lifts silk
Bar stretches out babinet upward and the sealing of telescopic sleeve 10 is socketed on extension, and telescopic sleeve lower end is connected on babinet, and upper end connects
It is connected on elevating screw top or top.
