Abstract
The invention discloses a driving device for an elevator cage door. The driving device comprises a cage door and a linear reciprocating moving device which is connected to the cage door, wherein the linear reciprocating moving device comprises a rotary driving device, a sliding slot, a screw rod and sliding bases; the screw rod is connected to an output end of the rotary driving device; two ends of the screw rod are supported on the sliding slot through bearings; the screw rod is designed as a first screw rod branch and a second screw rod branch which are different in helix direction and are symmetrically arranged at two sides of the middle part of the screw rod; the first screw rod branch and the second screw rod branch both are connected to the cage door through the sliding bases; one end of the sliding base is in threaded connection with the screw rod through a ball bearing while the other end of the sliding base is fixed with the cage door by passing through the bottom of the sliding slot; and the bottom of the sliding slot and each sliding base are connected by an idler wheel-sliding rail mechanism. The driving device provided by the invention utilizes a linear reciprocating moving function of a screw mechanism to realize the opening and closing of the elevator cage door, thereby being capable of efficiently locking the elevator cage door. The driving device is simple in structure and is more convenient in control.
Description
Technical field
The present invention relates to a kind of actuating device of elevator cab door.
Background technology
In the prior art, elevator cab door is a kind of sliding type door panel structure, realizes opening or closing of car door through electronic gating device.Existing gating device complex structure, the locking precision is not high.
Summary of the invention
The present invention is directed to the deficiency of prior art, a kind of actuating device of elevator cab door is provided, it is through adopting the past complex line locomotive function of screw body, to realize the folding of elevator cab door.Hence one can see that, the mode of the present invention through being threaded, and effective locking of realization elevator cab door, simultaneously, the present invention is simple in structure, and it is also comparatively convenient to control.
For realizing above technical purpose, the present invention will take following technical scheme:
A kind of actuating device of elevator cab door, comprise car door and with the reciprocal linear moving apparatus of car door bonded assembly, described reciprocal linear moving apparatus comprise rotating driving device, chute, with rotating driving device mouth bonded assembly screw rod and slide; Bearings is passed through on chute in the two ends of said screw rod; And it is the first screw rod split and the second screw rod split that screw rod is symmetrical set with the center; The hand of helix of the said first screw rod split and the second screw rod split is different, and in addition, the said first screw rod split all is connected with car door through slide with the second screw rod split; Said slide one end is connected with screw flight through ball bearing of main shaft; The other end then passes the bottom land and the car door of chute and fixes, and is connected through roller-sliding track mechanism between the bottom land of chute and the slide, and this roller-sliding track mechanism comprises corresponding roller and the slide rail that is provided with; Said slide rail is laid on the bottom land of chute, roller then with slide on set boss be connected.
The middle part of said screw rod is through connecting the bottom land of seat supports at chute.
According to above technical scheme, can realize following beneficial effect:
The present invention adopts screw body (being made up of screw rod, slide) to realize the folding of car door, and therefore, it can realize the locking of car door well.The present invention simultaneously is simple in structure, and it is also comparatively convenient to control.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Wherein: rotating driving device 1; The first screw rod split 21; The second screw rod split 22; Chute 3; Connect bearing 4; Slide 5; Car door 6.
The specific embodiment
Accompanying drawing discloses the structural representation of preferred embodiment involved in the present invention without limitation.Below will combine accompanying drawing that technical scheme of the present invention at length is described.
As shown in Figure 1; The actuating device of elevator cab door of the present invention; Comprise car door and with the reciprocal linear moving apparatus of car door bonded assembly, described reciprocal linear moving apparatus comprise rotating driving device, chute, with rotating driving device mouth bonded assembly screw rod and slide; Bearings is passed through on chute in the two ends of said screw rod; And it is the first screw rod split and the second screw rod split that screw rod is symmetrical set with the center; The hand of helix of the said first screw rod split and the second screw rod split is different, and in addition, the said first screw rod split all is connected with car door through slide with the second screw rod split; Said slide one end is connected with screw flight through ball bearing of main shaft; The other end then passes the bottom land and the car door of chute and fixes, and is connected through roller-sliding track mechanism between the bottom land of chute and the slide, and this roller-sliding track mechanism comprises corresponding roller and the slide rail that is provided with; Said slide rail is laid on the bottom land of chute, roller then with slide on set boss be connected.In the accompanying drawing, the middle part of said screw rod is through connecting the bottom land of seat supports at chute.Therefore, the present invention is the center to connect bearing, and screw rod is divided into two sections, and wherein one section is left-handed twist, and another section then is the right-hand helix setting.In addition, rotating driving device of the present invention can directly be a drive motor, also can be through the takeoff output after the deceleration transmission.
