These guide rails control the car's vertical movement. To enhance the riding experience, the guide rails must be precisely positioned along a reference line and installed within the elevator shaft. Each floor has landing doors for boarding and disembarking, which open and close in tandem with the car door. To ensure accurate installation, a support and positioning device is typically used to assist in positioning the car.

A horizontal member for adjusting the horizontal state of the adjustment plate 2 is provided in the device box 1.

[0026] The horizontal member includes multiple groups of electric telescopic rods 29 fixedly installed in the device box 1. The telescopic ends of the electric telescopic rods 29 are fixedly connected to the sliding disk 30. The outer wall of the sliding disk 30 is sleeved with a sleeve tube 31. The sleeve tube 31 is fixedly connected to a pressure sensor 42. The top of the sleeve tube 31 is fixedly connected to a limit ball 32. The outer wall of the limit ball 32 is provided with a limit block 33. The bottom surface of the limit block 33 is fitted and rolled with the outer wall of the limit ball 32 by setting a spherical groove. The top surface of the limit block 33 is provided with a plug-in groove 34. The bottom surface of the adjusting rod 27 is fixedly connected to a plug-in rod 35 that can be plugged into the plug-in groove 34.

[0027] The driving part includes a driving motor 36 fixedly installed in the device box 1. The model of the driving motor 36 is preferably YYHS-40. The output end of the driving motor 36 is coaxially fixedly connected to the first bevel gear 37. Four groups of threaded rods 38 are rotatably connected in the device box 1. One end of the threaded rod 38 is coaxially fixedly connected to the second bevel gear 39. The second bevel gear 39 is meshed with the first bevel gear 37. The four groups of threaded rods 38 respectively pass through the sliding frame 10 and are threadedly connected to the sliding frame 10.

[0028] Working principle: Place the device box 1 as a whole into the elevator shaft 41, pull the mounting brackets 8 around it, so that the support rod 3 slides in the guide frame 5, and at the same time, the guide frame 5 swings and slides in the arc groove 6 through the guide block 7, so that the support rod 3 can be extended and retracted while completing the angle adjustment, so that the mounting bracket 8 can reach any suitable size of the inner wall corner of the elevator shaft 41, and fix the mounting bracket 8 in the elevator shaft 41 through bolts and other connecting parts. At this time, the device box 1 can rock in the middle position, and at this time, the drive motor 36 is controlled to run, driving the first bevel gear 37 to rotate, so that the second bevel gears 39 around it drive the threaded rod 38 to rotate. The threaded rod 38 drives the sliding frame 10 to slide and adjust along the inner wall of the device box 1 until the support plates 13 on all sides conflict with the inner wall of the elevator shaft 41. Since the internal vertical cross-section of the elevator shaft 41 is generally a square or a rectangle close to a square, at this time, through the conflict between the two relative groups of support plates 13, the sliding displacement of the four groups of sliding frames 10 is the same, so that the device box 1 can be pushed to a relatively centered position. The support plate 13 that first conflicts with the inner wall of the elevator shaft 41 will first compress the first spring 12, causing the device box 1 to shift to the opposite side until the elastic force of the first springs 12 on both sides is relatively uniform, indicating that the device box 1 is now in a relatively centered position.

[0029] Since the shape of the inner wall of the elevator shaft 41 is generally close to a square, the first springs 12 are set around it, so that the support plate 13 on the shorter side can first contact the inner wall of the elevator shaft 41, and then the sliding frame 10 continues to slide to make the first spring 12 continue to compress, keeping the position of the support plate 13 relatively fixed, until the support plates 13 on the other two sides contact the inner wall of the elevator shaft 41 to complete the limit support. By arranging rollers 24 on the side of the support plate 13, during the process of automatically assisting the centering of the device box 1, the support plate 13 can slide more smoothly along the inner wall of the elevator shaft 41 to reduce friction. For some rectangular elevator shafts 41, a sliding frame 10 with a length-to-width ratio close to the inner side of the elevator shaft 41 can be used for installation in the initial state to ensure stability during the contact limit process.

[0030] When the first spring 12 is compressed, the hydraulic oil in the sleeve 11 is squeezed into the delivery pipe 14 and transported to the storage tank 22 through the guide pipe 15. The pressure in the storage tank 22 increases, pushing the arc plate 21 downward, and the bottom of the arc plate 21 can only push the lifting tube 17 downward, and the middle groove fits the outer wall of the fixing rod 16. The lifting tube 17 presses the second spring 20 while pushing the limit rod 19 downward. The bottom surface of the limit rod 19 and the top surface of the support rod 3 are relatively rough, so that the limit rod 19 can assist in limiting the position of the support rod 3 in the process of moving down and contacting the support rod 3, preventing the support rod 3 from continuing to slide arbitrarily in the guide frame 5, and the arc plate 21 can squeeze the top surface of the lifting tube 17 and the fixing rod 16, to assist in limiting the position and rotation angle of the guide frame 5, and finally make the position of the device box 1 more stable.

[0031] Place the adjustment plate 2 on top of the device box 1, and slide the adjustment rod 27 to make the lower plug-in rod 35 plug into the plug-in slot 34 to complete the installation of the adjustment plate 2. Since the adjustment plate 2 is in a top surface position and the friction is relatively severe, it is easy to deform and wear after long-term use, making it difficult to adjust to a horizontal state. Therefore, by setting up this device, the docking between the plug-in rod 35 and the plug-in slot 34 can be facilitated, so that the adjustment plate 2 can be disassembled and replaced more conveniently.

[0032] By observing the bubble position of the level bubble 28, the extension length of the electric telescopic rod 29 below is adjusted. When the electric telescopic rod 29 on one side pushes the sliding plate 30 up, the sliding plate will push the sleeve pipe 31 so that the limit ball 32 will lift the limit block 33, thereby moving the position of the adjustment plate 2 on that side up. In order to avoid getting stuck during this process, the adjustment plate 25, the adjustment cavity 26 and the limit ball 32 are provided. In the process of raising and lowering the adjustment plate 2 and leveling it, the adjustment plate 25 can swing in the adjustment cavity 26, and the limit ball 32 can roll in all directions in the limit block 33, so that the adjustment plate 2 can maintain a certain degree of limit in the process of adjustment without excessive shaking. In the process of adjustment of the adjustment plate 2, the rest The limiting ball 32 and the limiting block 33 in the respective positions will rotate accordingly, and at the same time, the adjusting disk 25 will also swing and slide in the adjusting cavity 26 to ensure that the horizontal state of the adjusting plate 2 is adjusted while the position of the electric telescopic rod 29 remains unchanged. The sliding disk 30 will also slide in the sleeve tube 31 to avoid affecting the adjustment of the height of the adjusting plate 2. After the horizontal adjustment is completed, by detecting the reading of the pressure sensor 42, it is determined which electric telescopic rod 29's top surface is in a state without supporting the sleeve tube 31, and the electric telescopic rod 29 in this position is started again, so that the sliding disk 30 moves up to support the pressure sensor 42 to set the strength. Finally, it is necessary to ensure that the adjusting plate 2 is in a horizontal state while all the pressure sensors 42 have the same readings.

[0033] After that, the car chassis 40 can be installed above the adjusting plate 2. By adjusting the position of the positioning plates 4 around the four sides, the positioning plates 4 can be slid onto the sliding frame 10 to the desired position and then fixed by the limit bolts, the car chassis 40 can be fixed and clamped, and the level of the car chassis 40 can be ensured. Then, the side panels and the top panel can be further installed above the car chassis 40 to complete the installation operation of the entire car. After installation, the control drive motor 36 is controlled to rotate in the opposite direction, and the sliding frame 10 slides in the opposite direction. The first spring 12 rebounds and the hydraulic oil in the storage tank 22 is pumped into the socket tube 11. The second spring 20 rebounds and the tension spring 23 pulls back, which can make the curved plate 21 and the lifting tube 17 move up, releasing the limit on the guide frame 5 and the support rod 3. Then, the connection between the mounting frame 8 and the elevator shaft 41 is released. After controlling the elevator car to rise, the device box 1 can be removed and taken out from the elevator shaft 41 as a whole.

[0034] It is worth noting that: due to the different sizes inside the elevator shaft 41 and certain errors in the construction process, it is necessary to specially customize corresponding support and positioning devices when installing the car chassis 40 for different elevator shafts 41. After the device is installed, its surface needs to be adjusted to a horizontal state. The existing method is to directly adjust the position and angle of the connection between the device and the elevator shaft 41 to level it. The operation is cumbersome and inefficient. This solution can be applied to elevator shafts 41 of different sizes for fixed use. At the same time, it can automatically adjust and fix the position of the device box 1 during use, and the leveling of the adjustment plate 2 is more flexible and efficient. A controller can be set in the device box 1 to automatically identify the horizontal state of the adjustment plate 2 and control multiple groups of electric telescopic rods 29 for lifting and lowering adjustment. A corresponding number of control buttons can also be set on the side of the device box 1 to manually control and fine-tune the telescopic length of different electric telescopic rods 29. After use, the sliding frames 10 and support rods 3 on all four sides of the device can be moved and stored relative to the side of the device box 1 for convenient transportation and use.
