The utility model provides a balancing device for a side-opening door machine, and the device comprises a door-machine main body board, a belt driving mechanism disposed on the door-machine main body board, a belt which is driven by the belt driving mechanism to revolve, and a side-opening door plate which moves left and right along with the belt. The belt is also connected with a balance weight which moves left and right along with the belt. During the revolving of the belt, the motion direction of the balance weight is opposite to the motion direction of the side-opening door plate. Compared with the prior art, the device provided by the utility model is provided with the balance weight on the door-machine main body board, wherein the motion direction of the balance weight is opposite to the motion direction of the side-opening door plate, thereby enabling the center of gravity of a lift car to remain at the center when the side-opening door plate moves towards a side, and preventing the center-of-gravity shift from causing the deformation of the lift car or the operating unsmoothness of the door machine, guaranteeing that the structure is more stable during the opening and closing of an elevator, and guaranteeing the operation is more smooth.
Description
Technical field
The utility model relates to the side opening door door machine balancing device on a kind of elevator.
Background technology
The side opening door door machine of elevator, conventionally all comprise a machine main board, be arranged on leather belt driving mechanism on a machine main board, by leather belt driving mechanism drive rotating belt, with the side opening door door-plate of belt side-to-side movement.When switch gate, side opening door door-plate moves to a machine one side, can cause car centre-of gravity shift, easily produces distortion.Especially when door opening width is close with car width, door is when opening, excessive because of centre-of gravity shift, can cause operation not smooth.
Summary of the invention
In view of this, in order to overcome the defect of prior art, the purpose of this utility model is to provide a kind of side opening door door machine balancing device, and the centre-of gravity shift problem causing when the switch gate to solve side opening door is stable to guarantee elevator car door system.
For achieving the above object, the utility model provides a kind of side opening door door machine balancing device, comprise a machine main board, be arranged on leather belt driving mechanism on described door machine main board, by described leather belt driving mechanism drive rotating belt, with the side opening door door-plate of described belt side-to-side movement, it is characterized in that: on described belt, be also connected with the equilibrate counterweight with described belt side-to-side movement, during the revolution of described belt described in the sense of motion of equilibrate counterweight contrary with the sense of motion of described side opening door door-plate.
Preferably, described side opening door door machine device also comprises the guide rail being installed on described door machine main board, and described guide rail extends along left and right directions, and described equilibrate counterweight can be connected on described guide rail slidingly.
Further, described guide rail is C type groove guide rail, and Open Side Down arranges for it, and described equilibrate counterweight is positioned at the below of described C type groove guide rail; In described C type groove guide rail, be provided with roll wheel assembly, the lower end of described roll wheel assembly is fixedly connected with described equilibrate counterweight from the opening of described C type groove guide rail stretches out.
Further, the upper end of described door machine main board has the top board connecting portion of bending forward, and described guide rail is fixed on described top board connecting portion.
In one embodiment, described equilibrate counterweight is positioned at described belt top, and described belt is fixedly connected on the lower surface of described equilibrate counterweight by pressing plate.
Compared to prior art, the utlity model has following advantage: by an equilibrate counterweight contrary with the sense of motion of side opening door door-plate is set on door machine main board, while making side opening door door-plate to a lateral movement, the center of gravity of car still remains on midway location, avoids the car distortion or the door machine that because of centre-of gravity shift, cause to move not smooth.Adopt elevator of the present utility model, when switch gate, car structure is more stable, and the work of door machine is also more smooth and easy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that A-A in Fig. 1 is to generalized section.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is elaborated.
Refer to Fig. 1 and Fig. 2, a side opening door door machine balancing device, comprise a machine main board 10, be arranged on leather belt driving mechanism 20 on a machine main board 10, by leather belt driving mechanism 20 drive rotating belt 30, with the side opening door door-plate 40 of belt 30 side-to-side movements.The upper end of side opening door door-plate 40 is connected on belt 30, and when belt 30 is driven revolution by leather belt driving mechanism 20, side opening door door-plate 40, along with belt 30 side-to-side movements, is realized switch gate.Wherein, leather belt driving mechanism 20 comprises buncher and belt pulley.
The upper end of door machine main board 10 has the top board connecting portion 11 of bending forward, and the guide rail 1 that extend horizontal left and right is installed on top board connecting portion 11.In the present embodiment, guide rail is C type groove guide rail, and it has the chute of offering along its length, and Open Side Down arranges.In described C type groove guide rail, be provided with roll wheel assembly 2, roll wheel assembly 2 can move and be arranged in C type groove guide rail along left and right directions.The lower end of roll wheel assembly 2 is fixedly connected with the equilibrate counterweight 3 that is arranged on guide rail 1 below from the opening of described C type groove guide rail stretches out.Equilibrate counterweight 3 is connected with belt 30 by the pressing plate 4 of below, and when belt 30 revolution, equilibrate counterweight 3 is along with belt 30 side-to-side movements.Equilibrate counterweight 3 departs from the centre-of gravity shift of the car that midway location causes while opening the door because of side opening door door-plate 40 for balance.Therefore, under optimal cases, the weight of equilibrate counterweight 3 is selected identical with the weight of side opening door door-plate 40, and the center-of-gravity position of equilibrate counterweight 3 should be symmetrical with the center-of-gravity position of side opening door door-plate 40.Equilibrate counterweight 3 is in motion process time, and the gravity Main Function of himself is on guide rail 1.In the present embodiment, equilibrate counterweight 3 is positioned at the top of belt 30, and the pressing plate 4 that belt 30 is greater than belt 30 by a width is fixed on the lower surface of equilibrate counterweight 3, and the both sides of pressing plate 4 are by screw 5 and equilibrate counterweight 3 lockings.
Belt 30 is comprised of the two sections of motion opposite direction when turning round, and equilibrate counterweight 3 is connected with the epimere of belt 30, and side opening door door-plate 40 is connected with the hypomere of belt 30.When leather belt driving mechanism 20 drives belt 30 revolution, side opening door door-plate 40 is contrary with the sense of motion of equilibrate counterweight 3.Therefore, when side opening door door-plate 40 is positioned at maximum opening position, equilibrate counterweight 3 is also positioned at apart from side opening door door-plate 40 distance positions farthest, thereby makes the center of gravity of car remain on roughly midway location, avoids causing because centre-of gravity shift is excessive car distortion or door machine to open the door not smooth.
Above-described embodiment is only explanation technical conceive of the present utility model and feature; its object is to allow person skilled in the art can understand content of the present utility model and implement according to this; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection domain of the present utility model.
