Description

Technical Field

[0001] The present application relates to a mounting bracket, and in particular to an elevator door machine mounting bracket used in the field of elevator door machines. Background Art

[0002] The elevator door machine mounting bracket can ensure the positioning and correct installation of the elevator door machine, so that the elevator door machine reaches a precise position in both horizontal and vertical directions, ensuring the stability and reliability of the elevator door machine operation, providing support during elevator operation, and improving the efficiency and convenience of elevator installation and maintenance.

[0003] The existing elevator door machine mounting bracket may not be applicable when the elevator door machine brand is different or the installation environment changes, and the original mounting bracket may need to be replaced or modified, which wastes installation time and increases installation costs. During frequent high-speed movement and door opening and closing, the mounting bracket may be slightly deformed or displaced due to vibration. This deformation or displacement will affect the accuracy of the elevator door machine operation and cause the door to open unsmoothly. In addition, there is a lack of intelligence in the maintenance and installation process, which makes the installation reliability need to be improved, and the maintenance efficiency also has a lot of room for improvement. In addition, the important components of the elevator door machine are exposed for a long time and are easily affected by dust, moisture, etc.

[0004] The purpose of this application is to improve the applicability of the elevator door machine mounting bracket to different elevator door machine models and different working environments, so as to save installation time and reduce economic costs; improve the stability of the mounting bracket to reduce the impact of the door machine on the deformation or displacement of the mounting bracket; improve the intelligence of the installation process, making the installation process more reliable, reducing safety hazards caused by human negligence, improving the efficiency of the maintenance process, and providing protection for important components of the elevator door machine. Utility Model Content

[0005] The purpose of the present application is to improve the scope of application of the elevator door machine mounting bracket, improve the stability of the mounting bracket and the elevator door machine, make the installation process more reliable and efficient, and provide an elevator door machine mounting bracket compared to the prior art, which is movably connected to the car fixing bracket and the door machine fixing bracket through the upper end of the vertical bracket, the car fixing bracket is movably connected to the car through bolts, the lower end of the door machine fixing bracket is movably connected to the motor protection box, and the lower end of the motor protection box is movably connected to the elevator door machine, the horizontal support platform, the car fixing bracket and the door machine fixing bracket all adopt a double-layer structure and are fixedly connected by springs, and friction plates are arranged between the double-layer structures, and openings are provided at the four corners of the horizontal and vertical surfaces of the car fixing bracket, four openings are provided on the side where the door machine fixing bracket is connected to the vertical bracket, and three openings are provided on the side where the door machine fixing bracket is connected to the elevator door machine.

[0006] The disassembly and splicing of different parts can improve the application of elevator door machine mounting bracket to different elevator door machine models and different working environments. The mounting bracket is subjected to the vertical impact force when the elevator is running. It adopts a double-layer structure with springs and friction plates in the middle to absorb and buffer the vibration generated during operation, reduce noise, and improve the stability of the mounting bracket and elevator door machine. The motor protection box can greatly reduce the impact of dust, moisture, etc. on important components of the elevator door machine.

[0007] Furthermore, a shock-absorbing plate is provided between the bolt and the nut, a pressure sensor is provided inside the shock-absorbing plate, and the pressure sensor is electrically connected to the indicator light, thereby improving the intelligence of the mounting bracket and reducing the impact of human errors.

[0008] Furthermore, a uniform long strip opening is provided on the vertical bracket, and the spacing between the vertical bolts of the door machine fixing bracket and the car fixing bracket is smaller than the length of the long strip opening of the vertical bracket, and the spacing between the vertical bolts of the door machine fixing bracket and the car fixing bracket is larger than the spacing between the long strip opening of the vertical bracket. This allows the mounting bracket to adapt to different elevator door machine models and different environments while ensuring that there are at least three bolts connecting the elevator door machine and the mounting bracket, and the car and the mounting bracket at the same time, thereby improving the connection stability between the door machine and the mounting bracket.

[0009] Compared with the existing technology, the advantages of this application are:

[0010] (1) By combining the components of the mounting bracket, the applicable scope and environment of the mounting bracket are improved.

[0011] (2) The double-layer structure of the horizontal support platform, car fixing bracket and door machine fixing bracket, as well as the design of adding springs and friction plates, can absorb the vibration of the elevator door machine and mounting bracket during the operation of the elevator and reduce the noise generated.

[0012] (3) Through the setting of the pressure sensor in the shock absorber and the indicator light on the motor protection box, it can be clearly seen through the indicator light whether the connection conditions between each bolt meet the requirements, reducing the safety hazards caused by manual operation errors and improving work efficiency.

[0013] (4) By designing the length and spacing of the bracket opening, it is ensured that at least three bolts are connected at the same time, thereby improving the stability of the connection between the mounting bracket and the elevator door machine.

[0014] (5) By setting up the motor protection box, the impact caused by the exposure of important parts of the elevator door machine is reduced, and the service life of the elevator door machine is improved. BRIEF DESCRIPTION OF THE DRAWINGS

The lower end of the vertical bracket 1 is slidably connected with the horizontal support platform 4, the horizontal support platform 4, the car fixing bracket 2 and the door machine fixing bracket 3 all adopt a double-layer structure, and a spring 9 is fixedly connected in the middle. A friction plate 18 is provided between the double layers of the horizontal support platform 4, the car fixing bracket 2 and the door machine fixing bracket 3; the four corners of the horizontal and vertical surfaces of the car fixing bracket 2 are provided with openings, and the door machine fixing bracket 3 is provided with a spring 9. Four openings are provided on the side where the fixed bracket 3 is connected to the vertical bracket 1, three openings are provided on the side where the door machine fixing bracket 3 is connected to the elevator door machine 8, and a uniform long strip opening 14 is provided on the vertical bracket 1. The spacing between the installation positions of the vertical bolts 10 of the door machine fixing bracket 3 and the car fixing bracket 2 is less than the length of the long strip opening 14 of the vertical bracket 1, and the spacing between the installation positions of the vertical bolts 10 of the door machine fixing bracket 3 and the car fixing bracket 2 is greater than the spacing between the long strip openings 14 of the vertical bracket 1. The purpose is to ensure that there are at least three connection points between the two components at the same time during installation, thereby improving stability and reliability. The vertical bracket 1, the car fixing bracket 2, the door machine fixing bracket 3, the horizontal support platform 4, and the spring 9 are all made of high-strength corrosion-resistant materials.

[0028] See also Figure 1 and Figure 8 During the installation of the elevator door machine, first install the car fixing bracket 2 on the car, then connect the vertical bracket 1 with the car mounting bracket 2, and after adjusting the vertical and horizontal positions of the car mounting bracket 2 and the vertical bracket 1, place the elevator door machine 8 on the upper end of the horizontal support platform 4, which solves the problem of the elevator door machine 8 being difficult to place during installation. Then connect the elevator door machine 8 to the vertical bracket, and then connect one end of the door machine fixing bracket 3 to the vertical bracket 1, and the other end to the motor protection box 5 and the elevator door machine 8. Finally, connect the elevator door machine to the vertical bracket 1. The above connected components are fixed with bolts 10, shock absorbers 12 and nuts 11. After completion, check whether there is any leakage in the installation or no tightening.

[0029] Example 2:

[0030] See also Figure 6 and Figure 7An indicator light 6 is fixedly connected to the upper end of the motor protection box 5. A shock-absorbing plate 12 is threadedly connected to the end of the bolt 10 near the nut 11. A pressure sensor 13 is provided inside the shock-absorbing plate 12. A switch 17 is provided at the right end of the indicator light 6. A battery pack 16 is provided to the right side of the switch 17. The indicator light 6 is electrically connected to the pressure sensor 13, the switch 17 and the battery pack 16. When the pressure sensor 13 reaches the set threshold, the corresponding indicator light 6 will light up.

[0031] After the bolts 10, shock-absorbing plates 12 and nuts 11 are installed, the indicator lights 6 at the upper end of the motor protection box 5 are observed. If the corresponding indicator light 6 is on, it means that the corresponding pressure sensor 13 meets the set pressure and the corresponding position has been tightened. Otherwise, it is necessary to tighten again or check whether the bolts 10, nuts 11, indicator lights 6 and shock-absorbing plates 12 are damaged until the specified pressure is reached and the indicator light 6 is on. The above steps need to be repeated for each bolt 10, nut 11 and shock-absorbing plate 12 installed. After all the installation is completed, check whether all the indicator lights 6 are normally lit. After the inspection, turn off the switch 17 that controls the indicator lights 6, and turn on the switch 17 when necessary to observe the indicator lights 6 to reduce the impact of manual operation errors. In subsequent maintenance, you can also quickly judge and find the position that needs to be reinforced by observing the indicator lights 6, which saves the time of manual inspection one by one and improves work efficiency.

[0032] It should be noted that before starting the installation, those skilled in the art can set the threshold of the pressure sensor 13, as well as the elastic coefficient of the spring 9 and the friction force of the friction plate 18 according to the tightening standard. In this application, the connection method between the pressure sensor 13, the indicator light 6, the switch 17, the battery pack 16 and the debugging process of the pressure sensor 13, the spring 9 and the friction plate 18 are well-known technologies to those skilled in the art and will not be elaborated here.

[0033] The above is only the best implementation method adopted by this application in combination with current actual needs, but the scope of protection of this application is not limited to this.
