Description

Technical Field

[0001] The present application belongs to the technical field of elevators, and in particular relates to an automatic swing door for a household elevator. Background Art

[0002] At present, most of the automatic swing doors on the market use a control method that combines dual motors and controllers. When the swing door machine receives a door opening command, the two motors start working and rotate the door leaf 90 degrees horizontally and open it. However, this door opening method often lacks control accuracy and cannot achieve synchronous opening of the two door leaves. If only one of the motors does not work, the other half of the door panel will not be able to open.

[0003] Therefore, designing an automatic swing door for an elevator that can achieve synchronous opening and closing of two door leaves has become a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0004] In view of the above-mentioned shortcomings or deficiencies of the prior art, the technical problem to be solved by the present application is to provide an automatic swing door for a home elevator.

[0005] To solve the above technical problems, this application is implemented through the following technical solutions:

[0006] The present application proposes an automatic swing door for a household elevator, comprising: an elevator frame installed in an elevator shaft, a left elevator door and a right elevator door installed on the elevator frame,

[0007] a control mechanism mounted on an upper side of the elevator frame;

[0008] A driving mechanism, wherein the driving mechanism is electrically connected to the control mechanism;

[0009] A synchronization mechanism, the left elevator door and the right elevator door are both equipped with the synchronization mechanism and the driving mechanism is connected to the synchronization mechanism;

[0010] The tensioning mechanism is arranged in the middle of the elevator frame and its two ends are connected with the synchronization mechanism through a traction rope.

[0011] Furthermore, an automatic swing door for a home elevator also includes: a guide wheel, one end of the traction rope is connected to the tensioning mechanism, and the other end of the traction rope is connected to the synchronization mechanism after being wound around the guide wheel.

[0012] Furthermore, at least two groups of guide wheels are provided.

[0013] Furthermore, the synchronization mechanism includes: a left synchronization wheel installed on the left elevator door, a right synchronization wheel installed on the right elevator door, a left synchronization belt wound around the left synchronization wheel, and a right synchronization belt wound around the right synchronization wheel.

[0014] Furthermore, one end of the left synchronous belt is wound around the left synchronous wheel, and the other end thereof is fixedly connected to the synchronous belt reverse buckle.

[0015] Furthermore, one end of the right synchronous belt is wound around the right synchronous wheel, and the other end thereof is connected to a traction rope wound around the guide wheel.

[0016] Furthermore, a first mounting portion is provided on one side of the elevator frame, and the left synchronous wheel is mounted on the first mounting portion through a first rotating shaft; a second mounting portion is provided on the other side of the elevator frame, and the right synchronous wheel is mounted on the second mounting portion through a second rotating shaft.

[0017] Furthermore, a spiral bevel gear is sleeved on the first rotating shaft, and the spiral bevel gear is meshedly connected with the driving gear of the driving mechanism.

[0018] Further, one end of the first rotating shaft is installed in the first mounting part, and the other end thereof is installed at the upper end of the left elevator door, and the lower end of the left elevator door is connected to the third rotating shaft; one end of the second rotating shaft is installed in the second mounting part, and the other end thereof is installed at the upper end of the right elevator door, and the lower end of the right elevator door is connected to the fourth rotating shaft.

[0020] Compared with the prior art, this application has the following technical effects:

[0021] (1) The present application uses only one set of driving mechanism and control mechanism. The driving gear of the driving mechanism meshes with the spiral bevel gear arranged on the first rotating shaft to drive the synchronous wheel on the left. At this time, the left synchronous belt is connected to the middle tensioning mechanism through the traction rope wrapped around the guide wheel, driving the right synchronous wheel wrapped in the opposite direction with the right synchronous belt to rotate, thereby realizing the automatic opening or closing of the elevator swing door synchronously. Moreover, each mechanism is simple, occupies a small space, is easy to adjust, is not easy to deform, and is safer and more reliable to use. The tension of the traction rope and the synchronous belt can be judged by the compression amount of the tensioning mechanism, without the need to borrow professional tension detection equipment.

[0030] like Figures 1 to 4 As shown, in one of the embodiments of the present application, the present application proposes an automatic swing door for a home elevator, comprising: an elevator frame 1 installed in an elevator shaft, a left elevator door 2 and a right elevator door 3 installed on the elevator frame 1, a control mechanism 9, the control mechanism 9 being installed on the upper side of the elevator frame 1; a driving mechanism 4, the driving mechanism 4 being electrically connected to the control mechanism 9; a synchronization mechanism, the left elevator door 2 and the right elevator door 3 are both equipped with the synchronization mechanism and the driving mechanism 4 is connected to the synchronization mechanism; a tensioning mechanism 10, the tensioning mechanism 10 is arranged in the middle of the elevator frame 1 and the two ends are connected to the synchronization mechanism through a traction rope 17.

At this time, the left synchronous belt is connected with the middle tensioning mechanism through the traction rope wrapped around the guide wheel, driving the right synchronous wheel reversely wrapped with the right synchronous belt to rotate, thereby realizing the synchronous opening or closing of the automatic swing door of the elevator. Moreover, each mechanism is simple, occupies a small space, is easy to adjust, is not easy to deform, and is safer and more reliable to use. The tension of the traction rope and the synchronous belt can be judged by the compression amount of the tensioning mechanism, and there is no need to borrow professional tension detection equipment.

[0031] Furthermore, in this embodiment, an automatic swing door for a home elevator further includes: a guide wheel 8, one end of the traction rope 17 is connected to the tensioning mechanism 10, and the other end thereof is connected to the synchronization mechanism after being wound around the guide wheel 8.

[0032] Furthermore, in this embodiment, at least two groups of guide wheels 8 are provided.

[0033] Preferably, if Figure 5 As shown, in this embodiment, the left and right sides of the tensioning mechanism 10 are respectively provided with a first guide wheel 81, a second guide wheel 82, a third guide wheel 83 and a fourth guide wheel 84. This is conducive to better controlling the opening or closing direction of the door leaves on the left and right sides, avoiding direction deviation, and making adjustment more convenient.

[0034] Furthermore, in this embodiment, the synchronization mechanism includes: a left synchronous wheel 6 installed on the left elevator door 2, a right synchronous wheel 7 installed on the right elevator door 3, a left synchronous belt 61 wound around the left synchronous wheel 6, and a right synchronous belt 71 wound around the right synchronous wheel 3.

[0035] Furthermore, in the present embodiment, one end of the left synchronous belt 61 is wound around the left synchronous wheel 6 , and the other end thereof is fixedly connected to the synchronous belt reverse buckle 62 .

[0036] Furthermore, in the present embodiment, one end of the right synchronous belt 71 is wound around the right synchronous wheel 7 , and the other end thereof is connected to the traction rope 17 wound around the guide wheel 8 .

[0037] Furthermore, in this embodiment, a first mounting portion 11 is provided on one side of the elevator frame 1, and the left synchronous wheel 6 is installed on the first mounting portion 11 through a first rotating shaft 12; a second mounting portion 13 is provided on the other side of the elevator frame 1, and the right synchronous wheel 7 is installed on the second mounting portion 13 through a second rotating shaft 14.

[0038] Furthermore, in this embodiment, a spiral bevel gear 5 is sleeved on the first rotating shaft 12 , and the spiral bevel gear 5 is meshedly connected with the driving gear 41 of the driving mechanism 4 .

Figure 2As shown, when the driving mechanism 4 receives the door opening instruction from the control mechanism 9, the driving mechanism 4 starts to work to rotate the left elevator door 2 and the right elevator door 3 90 degrees in the horizontal direction and open them.

[0040] Preferably, in this embodiment, one end of the tensioning mechanism 10 is connected to the left synchronous belt 61 wound around the left synchronous wheel 6 through a traction rope 17 wound around the left guide wheel 8, and the other end is connected to the synchronous belt 71 wound around the right synchronous wheel 7 through a traction rope 17 reversely wound around the right guide wheel 8. After the present application is installed on the elevator door machine, the elastic force of the tensioning mechanism 10 ensures that the mounting seat is always in a tensioned state, thereby ensuring that the synchronous belt is always in a tensioned state. Even after long-term use, the synchronous belt will become fatigued and longer, and it will be tightened under the action of the elastic force of the tensioning mechanism 10. Therefore, by using a tensioning mechanism of this structure, the continuous and stable tension of the synchronous belt can be ensured, thereby reducing safety hazards.

At this time, the left synchronous belt is connected with the middle tensioning mechanism through the traction rope wrapped around the guide wheel, which drives the right synchronous wheel wrapped around the right synchronous belt in the opposite direction to rotate, thereby realizing the synchronous opening or closing of the automatic swing door of the elevator; and each mechanism is simple, occupies a small space, is easy to adjust, is not easy to deform, and is safer and more reliable to use. The tension of the traction rope and the synchronous belt can be judged by the compression amount of the tensioning mechanism, and there is no need to borrow professional tension detection equipment.
