[0039] The driving piece comprises 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 with a first bevel gear 37, four groups of threaded rods 38 are rotationally connected in the device box 1, one end of each threaded rod 38 is coaxially fixedly connected with a second bevel gear 39, the second bevel gears 39 are in meshing connection with the first bevel gear 37, and the four groups of threaded rods 38 respectively penetrate through the sliding frames 10 and are in threaded connection with the sliding frames 10.

[0040] Working principle: the device box 1 is placed in the elevator shaft 41 as a whole, the mounting frames 8 around are pulled, the supporting rods 3 slide in the guide frames 5, the guide frames 5 swing and slide in the arc-shaped grooves 6 through the guide blocks 7, the supporting rods 3 can be stretched and contracted while the angle is adjusted, so that the mounting frames 8 can reach the corner of the inner wall of the elevator shaft 41 with any suitable size, the mounting frames 8 are fixed in the elevator shaft 41 through bolts and other connecting pieces, at this time, the device box 1 can shake at the middle position, at this time, the driving motor 36 is controlled to operate, the first bevel gear 37 is driven to rotate, the second bevel gears 39 around are driven to rotate, the threaded rods 38 are driven to slide along the inner wall of the device box 1, until the supporting plates 13 around abut against the inner wall of the elevator shaft 41, because the vertical section of the inside of the elevator shaft 41 is generally a square or a rectangle close to a square, at this time, the abutment of the opposite two groups of supporting 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 the relatively central position, the supporting plate 13 abutting against the inner wall of the elevator shaft 41 first compresses the first spring 12, so that the device box 1 is offset to the opposite side, until the elastic forces of the opposite first springs 12 on both sides are relatively uniform, indicating that the device box 1 is at the relatively central position.

[0041] Due to the shape of the inner wall of the elevator shaft 41 is generally close to a square, through the setting of the first spring 12, the support plate 13 on the shorter side can first abut against the inner wall of the elevator shaft 41, and then the sliding frame 10 continues to slide so that the first spring 12 is continuously compressed, keeping the relative position of the support plate 13 fixed, until the support plates 13 on the other two sides abut against the inner wall of the elevator shaft 41, and the limiting support is completed. By setting the roller 24 on the side of the support plate 13, the support plate 13 can slide more smoothly along the inner wall of the elevator shaft 41 during the automatic auxiliary centering of the device box 1, reducing friction. For some rectangular elevator shafts 41, a sliding frame 10 close to the length-width ratio of the inner side of the elevator shaft 41 can be used for installation in the initial state to ensure stability during the abutting and limiting process.

[0042] During the compression of the first spring 12, the hydraulic oil in the sleeve 11 is squeezed into the delivery pipe 14, and then delivered to the storage tank 22 through the guide pipe 15. The pressure in the storage tank 22 increases, pushing the arc-shaped plate 21 downward. The bottom of the arc-shaped plate 21 can only push the lifting pipe 17 downward, and the middle groove is in close contact with the outer wall of the fixed rod 16. The lifting pipe 17 pushes the limiting rod 19 downward while compressing the second spring 20. The bottom surface of the limiting rod 19 and the top surface of the support rod 3 are relatively rough, so that the limiting rod 19 can assist in limiting the position of the support rod 3 during the downward movement and abutting against the support rod 3, avoiding the support rod 3 from sliding arbitrarily in the guide frame 5. The arc-shaped plate 21 can extrude the top surface of the lifting pipe 17 and the fixed rod 16 to assist in limiting the position and rotation angle of the guide frame 5, finally making the position of the device box 1 more stable.

[0043] Place the adjusting plate 2 above the device box 1, and slide the adjusting rod 27 so that the lower plug-in rod 35 is plugged into the plug-in slot 34, and the installation of the adjusting plate 2 is completed. Since the adjusting plate 2 is at the top position and the friction is more serious, it is easy to deform and wear after a long time of use, making it difficult to adjust to a horizontal state. Therefore, by setting the device, the butt joint between the plug-in rod 35 and the plug-in slot 34 can be facilitated, so that the adjusting plate 2 can be more conveniently disassembled, replaced and replaced.

[0044] By observing the bubble position of the horizontal bubble 28, the extension length of the lower electric telescopic rod 29 is adjusted. When the electric telescopic rod 29 on one side pushes the sliding disc 30 to move upwards, the sliding disc pushes the sleeve pipe 31, so that the limiting ball 32 lifts the limiting block 33, thereby making the adjusting plate 2 on this side move upwards. In order to avoid the situation of being stuck, the adjusting disc 25, the adjusting cavity 26 and the limiting ball 32 are arranged, so that the adjusting disc 25 can swing in the adjusting cavity 26, and the limiting ball 32 can roll in the limiting block 33 in all directions during the lifting and leveling process of the adjusting plate 2, so that the adjusting plate 2 can be limited to a certain extent during the adjusting process, and the situation of excessive shaking does not occur. At the same time, the limiting ball 32 and the limiting block 33 on the rest position will produce corresponding rotation during the adjusting process of the adjusting plate 2, and the adjusting disc 25 will also swing and slide in the adjusting cavity 26, so as to realize the adjustment of the horizontal state of the adjusting plate 2 under the condition that the position of the electric telescopic rod 29 is unchanged. The sliding disc 30 will slide in the sleeve pipe 31, so as to avoid affecting the adjustment of the height of the adjusting plate 2. After the adjustment of the horizontal state is completed, the reading of the pressure sensor 42 is detected to determine which electric telescopic rod 29 is in the state of not supporting the sleeve pipe 31. The electric telescopic rod 29 at this position is started again, so that the sliding disc 30 moves upwards to support the pressure sensor 42 and set the strength, so as to finally ensure that the adjusting plate 2 is in a horizontal state and the readings of all pressure sensors 42 are the same.

[0045] Then the car chassis 40 can be installed above the adjusting plate 2. By adjusting the positions of the four surrounding positioning plates 4, the positioning plates 4 can slide on the sliding frame 10 to the required position and be fixed by the limiting bolts, so as to fix and clamp the car chassis 40 and ensure the horizontal state of the car chassis 40. Then the side plates and top plates can be further installed above the car chassis 40 to complete the installation operation of the car. After the installation is completed, the driving motor 36 is controlled to rotate in the reverse direction, the sliding frame 10 slides in the reverse direction, the first spring 12 rebounds to draw the hydraulic oil in the storage groove 22 into the sleeve 11, the second spring 20 rebounds, and the tension spring 23 is pulled back, so as to make the arc-shaped plate 21 and the lifting pipe 17 move upwards, and the limiting of the guide frame 5 and the supporting rod 3 is released. Then the connection between the mounting frame 8 and the elevator shaft 41 is released, the elevator car is controlled to rise, and then the device box 1 can be removed and taken out from the elevator shaft 41.

[0046] 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.
