A kind of elevating mechanism of screw rod transmission
Technical field
The present invention relates to a kind of elevating mechanisms of screw rod transmission.
Background technique
Currently, in parking systems, the elevating mechanism of lift-sliding mostly use greatly postposition type electric machine+reel+motor beam+
Wirerope or chain.Entire transmission mechanism cost is high, and production and installation are all more troublesome.If existing main motor brake damage
Bad, sweep directly will quickly be fallen, abnormally dangerous, jeopardize the personal safety of automobile and pick-up personnel.Using lead screw mode, i.e.,
Make brake failure, sweep will slowly be landed, and improve safety.
Summary of the invention
The purpose of the present invention is to overcome the above shortcomings, provides a kind of structurally reasonable, cheap, installation and transport
It is convenient, installation period is greatly reduced, and run the elevating mechanism of more steady, safety screw rod transmission.
The purpose of the present invention is achieved through the following technical solutions: a kind of elevating mechanism of screw rod transmission, including crossbeam and
Stringer, one end of the side rail inner be equipped with lifting motor, the both ends of the crossbeam be symmetrically installed with the first deflecting roller and
Second deflecting roller, the lifting motor are connected with ball screw by belt, and the both ends of the ball screw are fixed by screw rod
Plate is fixed in stringer, is connected with double flute movable pulley the middle part of the ball screw is symmetrical above and below, and steel wire is equipped in stringer
Rope clip is equipped with wirerope on the wirerope clip, and the wirerope is against being mounted in wirerope clip, in two institutes
The both ends for stating stringer are symmetrically arranged with the first suspension centre pulley, the second suspension centre pulley, third suspension centre pulley and four-point lifting pulley.
A further improvement of the present invention is that: the top rope groove of the steel wire penetrating double flute movable pulley turns by rope groove
To one end of the wirerope enters the first deflecting roller, and the first wire rope hole of steel wire penetrating after commutation, the wirerope is wherein
One end passes through the second suspension centre pulley and is connected with wherein the second suspension centre of sweep, and the other end of the wirerope passes through the first suspension centre
Pulley is connected with the first suspension centre of sweep, the second deflecting roller of steel wire penetrating described in another group, steel wire penetrating second after commutation
Wire rope hole, wherein one end is connected across third suspension centre pulley with the wherein third suspension centre of sweep the wirerope, the steel
The other end of cord passes through four-point lifting pulley and is connected with the four-point lifting of sweep.
Compared with the prior art, the present invention has the following advantages:
Structure is simple, cheap, and installation and transport are all more convenient than existing mode.Motor uses common asynchronous moter, is not necessarily to
Acceleration and deceleration case is compared with original transmission, and motor price wants cheap half, and screw rod reliable in action is stablized, and inside is using movable pulley+fixed
Pulley combination mode, transmission efficiency greatly increase, and entire gear unit can be good in factory-assembled, whole to ship, integral installation, greatly
Reduce installation period greatly.

Specific embodiment:
In order to deepen the understanding of the present invention, below in conjunction with embodiment and attached drawing, the invention will be further described, the implementation
Example for explaining only the invention, is not intended to limit the scope of the present invention..
As Fig. 1-2 shows a kind of embodiment of the elevating mechanism of screw rod transmission of the present invention: including crossbeam and stringer,
One end of the side rail inner is equipped with lifting motor 1, is symmetrically installed with the first deflecting roller 7-1 and second at the both ends of the crossbeam
Deflecting roller 7-2, the lifting motor 1 are connected with ball-screw 2 by belt, and the both ends of the ball-screw 2 are solid by screw rod
Fixed board 3 is fixed in stringer, is connected with double flute movable pulley 4 the middle part of the ball-screw 2 is symmetrical above and below, is equipped in stringer
Wirerope clip 5 is equipped with wirerope 6 on the wirerope clip 5, and the wirerope 6 is opposite to be mounted on wirerope clip 5
It is interior, the first suspension centre pulley A, the second suspension centre pulley B, third suspension centre pulley C and are symmetrically arranged at the both ends of two stringers
Four-point lifting pulley D;The wirerope 6 passes through the top rope groove of double flute movable pulley 4, turns to by rope groove, the one of the wirerope 6
End enters the first deflecting roller 7-1, and wirerope 6 passes through the first wire rope hole 8-1 after commutation, and the wirerope 6 wherein passes through one end
Second suspension centre pulley B is connected with wherein the second suspension centre of sweep, and the other end of the wirerope 5 passes through the first suspension centre pulley A
It is connected with the first suspension centre of sweep, wirerope 6 described in another group passes through the second deflecting roller 7-2, and wirerope 6 passes through second after commutation
Wire rope hole 8-2, wherein one end is connected across third suspension centre pulley B with the wherein third suspension centre of sweep the wirerope 6, institute
The other end for stating wirerope 5 passes through four-point lifting pulley A and is connected with the four-point lifting of sweep.
Elevator drives ball-screw by belt pulley, and double flute movable pulley is fixed on ball-screw, when ball-screw passes
When dynamic, double flute movable pulley moves forward and backward on ball-screw, and double flute movable pulley drives wirerope to do folding and unfolding movement, to realize
Elevating control of the wirerope to sweep.
The configuration of the present invention is simple, cheap, installation and transport are all more convenient than existing mode.Motor is using common asynchronous
Motor is compared without acceleration and deceleration case with original transmission, and motor price wants cheap half, and screw rod reliable in action is stablized, and inside uses
Movable pulley+fixed pulley integrated mode, transmission efficiency greatly increase, and entire gear unit can be good in factory-assembled, whole to ship, whole
Body installation, greatly reduces installation period.
