Specific embodiment
In order to further explain the technical solution of the present invention, being described in detail below by specific embodiment.
A kind of slow speed vertical elevator of the invention, as shown in figures 1 to 6, including elevator, the carriage 2 in elevator,
And the lifting drive that driving carriage 2 is gone up and down；Lifting drive includes four and corresponds along four corners of elevator
The driving screw mechanism of setting and four positioning mechanisms that each driving screw mechanism is limited one by one；Drive screw mechanism
Including vertically arranged threaded post 311, upper end base 312 set on 311 upper end of threaded post, and under 311 lower end of threaded post
End seat 313, and the motor 314 that driving threaded post 311 is rotated about axis；Each threaded post 311 is formed with multiple external thread sections 3111,
With multiple thin diameter sections 3112；Each external thread section 3111 and thin diameter section 3112 alternate and are arranged；External thread section 3111 has outer
Screw thread, and the external screw thread of adjacent external thread section 3111 has common helix；External thread section 3111 has with externally threaded
First diameter on the basis of tip, and the second diameter on the basis of externally threaded root；The diameter of thin diameter section 3112 is less than
Two diameters；
Carriage 2 has and the one-to-one case angle in each corner of elevator；Case angle is formed with the external thread section with threaded post 311
3111 internal thread parts 21 matched；
Positioning mechanism includes the limit monomer 321 that multiple threadingly columns 311 are arranged and connect with elevator sidewall 11；Limit
Monomer 321 includes the spacing collar 3211 covered at thin diameter section 3112, and to the locating piece that spacing collar 3211 is fixed；Spacing collar
3211 outer diameter is less than second diameter；Internal thread part 21 has at least one section of internal screw thread matched with external screw thread, and same section
The span of internal screw thread in the vertical direction is greater than the length of thin diameter section 3112.Present invention is mainly used for the deliveries of lowrise layer low speed, turn round
Power is big and steady, is not susceptible to accident.Lifting driving carried out to carriage 2 by four driving screw mechanisms, and each positioning mechanism
Driving screw mechanism can be limited, realize the steady running of driving screw mechanism, driving carriage 2 realizes smooth steady liter
Drop.Specifically, after having passenger to take carriage 2, controller controls each motor 314 and each threaded post 311 is driven to rotate synchronously, and utilizes
The external screw thread of threaded post 311 is matched with the internal thread part 21 of carriage 2, is balanced synchronous driving to 2 four case angles of carriage, is made
Carriage 2 realizes lifting action, and the present invention relies on screw drive, and power is big and stablizes, and the lifting action of carriage 2 is more steady suitable
Freely, the case where being less prone to all standing or moment speed-raising, seating is more comfortable, and carriage 2 is by four same time limits of threaded post 311
Position, is not in situation of falling, and carries out effective protection to passenger, safer.Upper end base 312 and lower end seat 313 can be to screw threads
Column 311 provides rotating fulcrum, keeps rotation more stable.And each thin diameter section 3112 can be entangled and be consolidated by each spacing collar 3211
It is fixed, on the basis of not influencing the rotation of threaded post 311, avoid the movement of 311 carry out level and up and down direction of threaded post, it is ensured that spiral shell
The more accurate stabilization of the rotation of line column 311.And the outer diameter of spacing collar 3211 is less than second diameter, in the interior spiral shell of internal thread part 21
Line is matched with the external screw thread of external thread section 3111 in the opposite sliding process of progress, and spacing collar 3211 is made not touch interior spiral shell
Line, it is ensured that internal thread part 21 is smooth with the sliding relatively of external thread section 3111.And same section of internal screw thread is in the vertical direction
Span is greater than the length of thin diameter section 3112, i.e., the internal screw thread on internal thread part 21 may span across any one end thin diameter section 3112 and with it is outer
External screw thread on thread segment 3111 is cooperated, and is ensuring that each spacing collar 3211 matches with thin diameter section 3112 to threaded post 311
On the basis of being limited, making thin diameter section 3112 not influences the relative motion of internal thread part 21 Yu external thread section 3111, will not go out
The case where existing internal thread part 21 is stuck in 3112 edge of thin diameter section, it is ensured that carriage 2 is gone up and down smooth steady.
Preferably, spacing collar 3211 includes the outer ring matrix in outside, and the interior and and thin diameter section set on outer ring matrix
3112 inner-ring bearings matched.For the present invention in practical work process, spacing collar 3211 passes through inner-ring bearing and thin diameter section
3112 match, and keep the rotation of threaded post 311 more smooth efficiently.Specific structure can be that each external thread section 3111 is independence
Structure, each external thread section 3111 are attached in such a way that thin diameter section 3112 uses grafting with adjacent external thread section 3111,
