Description

Technical Field

[0001] The present invention relates to the technical field of elevators, and particularly relates to an installation structure and an installation method for an elevator car door machine. Background Art

[0002] The traditional installation method of an elevator car door machine is to install the door machine on the elevator car frame, which is also a common installation method in the current elevator market. However, this installation method is difficult, time-consuming, and has high assembly requirements. To optimize the above defects, there have been significant technical adjustments in the installation method of the car door machine. Relevant documents include CN210064869U, CN111470400A, and CN209988930U. Among them, CN209988930U discloses a connection structure between a door machine board and a car. Compared with the traditional installation method of the car door machine, the car door machine is directly installed on the car through the upper plate at the entrance and exit. However, this installation method has the following technical problems:

[0003] 1. The reinforcing rib on the upper plate at the entrance and exit and the door machine connecting piece are integrally designed, making the installation of the upper plate at the entrance and exit more difficult. The specific details are as follows. As Figure 1 shown, there is a reinforcing rib on the upper plate at the entrance and exit. At the same time, there are four door machine connection holes on this reinforcing rib for installing the door machine. There are two installation holes of the upper plate at the entrance and exit on the back of the reinforcing rib. It is necessary to open a window on the reinforcing rib to allow a wrench to pass through the window to install the upper plate at the entrance and exit;

[0004] 2. This installation method cannot adjust the verticality of the door machine and cannot ensure the verticality of the door machine;

It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other. The following exemplary embodiments of the present invention can be implemented in many different forms and should not be construed as being limited only to the specific embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present invention complete and thorough, and to fully convey the technical solutions of these exemplary specific embodiments to those skilled in the art.

[0032] Embodiment 1

[0033] As Figures 2 to 5 shown, this embodiment provides an installation structure of an elevator car door machine, including a pair of first installation parts and a pair of second installation parts;

[0034] The first installation part includes a reinforcing rib 1, an upper pressing plate 2, a lower pressing plate 3, an upper mounting seat 4, and a fastener 5; the reinforcing rib is fixed at the upper plate 11 of the entrance and exit of the car and has a door machine connection hole 6.

[0035] The upper pressing plate 2 and the lower pressing plate 3 are both in the shape of a 90-degree bend. The upper pressing plate 2 is fixed at the upper part of the upper plate 11 at the entrance and exit of the car. One vertical surface of the upper pressing plate 2 presses on the outer surface of the stiffener 1. The vertical surface of the upper pressing plate 2 has a first door machine connection hole 6 corresponding to the door machine connection hole on the stiffener; the lower pressing plate 3 is fixed at the lower part of the upper plate 11 at the entrance and exit of the car, and one vertical surface of the lower pressing plate 3 presses on the outer surface of the stiffener 1.

[0036] The upper mounting seat 4 is fixed on the stiffener 1, and a part of the upper mounting seat 4 protrudes above the upper plate 11 at the entrance and exit. The protruding part of the upper mounting seat has a second door machine connection hole 7.

[0037] Since the components of the first door machine connection hole 6 and the second door machine connection hole 7 are separated, during the installation process, since the upper mounting seat 4 is installed later than the upper pressing plate 2, it is convenient to fix the screws above the upper plate at the entrance and exit, and the assembly is simple.

[0038] The second mounting member includes a side plate 8 and a fastener. The side plate 8 has a first connection surface and a second connection surface, and the first connection surface and the second connection surface are perpendicular to each other; the side plate 8 is connected to the side part of the upper plate 11 at the entrance and exit and the side part of the front wall 13 through the first connection surface; the second connection surface has a third door machine connection hole 16 for fixing the door machine.

[0039] As Figure 3 shown, the second mounting member further includes a threaded washer 12; the height of the first connection surface in the vertical direction is greater than that of the second connection surface; the fixing method of the side plate 8 is: fastening and clamping the front wall 13 and the upper plate 11 at the entrance and exit through the threaded washer 12 and the first connection surface.

[0040] During installation, use the threaded washer 12 and the bolt assembly 14 of M6X16 to fix the front wall 13 and the side plate 8 on the side of the upper plate 11 at the entrance and exit, and then use the threaded washer 12 and the bolt assembly 14 of M6X16 to further fix the front wall 13. The threaded washer 12 and the side plate 8 are used to clamp the flanges of the front wall and the upper plate at the entrance and exit. The threaded washer 12 is a steel plate with a certain thickness processed with threaded holes, generally with a thickness greater than 3 mm, which makes the local plate thickness at the connection thicker and improves the stress.

[0041] As Figure 5 shown, the first connection surface has a hook-shaped groove 15, and the hook-shaped groove 15 is used to support the door machine during door machine installation and make the second connection surface stick to the door machine. It is convenient for on-site workers to assemble a heavier door machine, and its limiting function can enable one person to install the door machine; the hook of the hook-shaped groove can effectively limit the position and prevent the door machine from tilting to effectively ensure the verticality of the door machine.

[0042] The technical effect analysis of the present invention compared with the existing door machine installation method is as follows:

[0043] In the existing installation structure of the door machine, the weight of the door machine is transmitted from the installation points on the upper plate of the entrance and exit to the car top, and the car top serves as the main bearing carrier. For the side plate added in the present invention, the weight of the door machine abuts against the hook-shaped groove of the side plate, and the side plate bears the main gravity. The side plate transmits the bearing capacity to the front wall, enabling the front wall to bear the vertical gravity of the door machine. The strength of the stressed object is related to the height of the stressed object in the stress direction. In the existing installation method, the height of the upper plate of the entrance and exit is generally 300 mm, with limited bearing capacity and prone to deformation of the pressed decorative surface. While the height of the front wall is at least over 2100 mm, which has sufficient ability to bear the vertical gravity. Additionally, the side plate has a certain thickness, more than 3 mm. The superposition of the thicknesses of the side plate, the flanges of the front wall and the upper plate of the entrance and exit, and the threaded gasket makes the connection part have sufficient thickness, locally improving the stress of the bolt connection.

[0044] Preferably, the fastening positions of the threaded gasket 12 and the first connection surface are close to the upper and lower parts of the upper plate 11 of the entrance and exit.

[0045] Preferably, the installation structure of the elevator car door machine further includes a vibration-proof film 17, and the vibration-proof film 17 is pasted on the back of the upper plate of the entrance and exit. As Figure 5 shown, the natural frequency of the upper plate of the entrance and exit can be changed through the vibration-proof film 17, thereby effectively reducing the resonance probability between the motor frequency and the upper plate of the entrance and exit when the car door is opened and closed, and improving the comfort.

[0046] Embodiment 2

[0050] Step S3, connecting the front wall and the car top;

[0051] Step S4, connecting the upper plate of the entrance and exit, the front wall and the side plate simultaneously;
