[0005] To solve the above technical problems, the following technical solutions are adopted in the present application:

[0007] The elevator car plate flattening device for the elevator use place is designed in the scheme, and the specific structure mainly consists of two parts, one part is arranged outside the car as the car outer supporting mechanism, which can provide a flat plane for the correction of the elevator plate, and then the car inner pressing mechanism, i.e. the horizontal pressure roller mechanism, can provide sufficient pressure for the flattened car plate, and the flattening work of the elevator car plate can be realized in the process of rolling in the vertical direction, the above structure is simple, the flattening efficiency is high, and the maintenance cost of the elevator can be effectively reduced by using the device in the scheme to flatten the car plate.

[0008] The supporting frame in the scheme can provide uniform supporting force for the car plate supporting panel, and prevent the deformation of the car plate supporting panel in the flattening process due to the excessive pressure of the horizontal pressure roller mechanism.

[0009] As a further preferred embodiment of the present application, the horizontal connecting structure is a horizontal connecting plate, and the horizontal connecting plate is fixedly connected with the car through connecting bolts.

[0010] The horizontal connecting plate is fixedly connected with the car through bolts, and such a connecting structure is simple and convenient for operation in the elevator shaft.

[0011] As a further preferred embodiment of the present application, the side surface of the horizontal connecting plate located at the top of the car is provided with a line plummet for checking the verticality.

[0012] In order to make the flattening effect optimal, the verticality of the car plate supporting panel needs to be checked by the line plummet, so that the outer surface of the flattened car plate can be ensured to be vertically arranged instead of being obliquely arranged.

[0013] As a further preferred embodiment of the present application, the line plummet is slidingly connected with the horizontal slide rail fixed on the side surface of the horizontal connecting plate through a line plummet sliding block, the top of the horizontal slide rail is provided with a screw type sliding block positioning mechanism, and the lower end of the screw type sliding block positioning mechanism penetrates through the top of the horizontal slide rail and contacts the top of the line plummet sliding block slidingly clamped in the slide groove in the bottom surface of the horizontal slide rail.

[0014] In addition to checking the verticality of the car plate supporting panel, the verticality of the surface of the supporting frame for supporting the car plate also needs to be checked, so that the inclination in the flattening process can be prevented, and therefore a sliding type line plummet needs to be designed to facilitate the verticality detection of different planes and adjust to the detection position, and the screw type sliding block positioning mechanism is used for pressing and positioning the line plummet.

[0015] As a further preferred embodiment of the present application, the support frame comprises a panel support plate and telescopic support rods, one side of the panel support plate is in contact with the outer surface of the car plate support panel, and the telescopic support rods are evenly arranged on the other side of the panel support plate, the telescopic support rods are arranged in the horizontal direction, and the other end of the telescopic support rods is screwed to the inner wall of the elevator shaft.

[0016] After years of use, the inner wall of the elevator shaft is not flat, so the support length can be adjusted by the telescopic support rods, for example, if the inner wall of the elevator shaft at a certain position is slightly concave, the telescopic support rod at that position can be lengthened, and if the inner wall of the elevator shaft at a certain position is convex, the telescopic support rod at that position can be shortened, so that the panel support plate remains vertical and provides uniform support force to the car plate support panel.

[0017] As a further preferred embodiment of the present application, the horizontal pressure roller mechanism comprises a screw rod type electric sliding rail, a push rod sliding block, a telescopic pressure roller connecting rod and a pressure roller, the screw rod type electric sliding rail is detachably fixed in the elevator car in the vertical direction, the push rod sliding block is slidingly arranged in the middle of the screw rod type electric sliding rail, the push rod sliding block is rotationally connected with the screw rod of the screw rod type electric sliding rail, the telescopic pressure roller connecting rod is horizontally arranged at the outer end surface of the push rod sliding block, the outer end surface of the push rod sliding block faces the inner surface of the car plate at the car correction surface, and the pressure roller is connected to the other end of the telescopic pressure roller connecting rod.

[0018] When using the horizontal pressure roller mechanism, first fix the screw rod type electric sliding rail in the car with bolts, then install the push rod sliding block on the screw rod type electric sliding rail, so that the push rod sliding block can be controlled to rise and fall by the screw rod of the screw rod type electric sliding rail. The screw rod type electric sliding rail is a prior art and will not be described in detail, the main structure is a sliding rail with a screw rod groove, a screw rod is arranged in the sliding rail along the direction of the sliding rail, the screw rod is connected with a motor, the middle part of the screw rod is threadedly connected with the push rod sliding block, and when the screw rod rotates, the push rod sliding block can only move up and down along the sliding rail because it is limited by the sliding rail. When the push rod sliding block moves up and down along the screw rod type electric sliding rail, the pressure roller connected with the push rod sliding block through the telescopic pressure roller connecting rod also moves synchronously, the surface of the pressure roller is in contact with the inner surface of the car plate, and the roller pressing type flattening work is completed, and the pressure applied by the pressure roller to the car plate is provided by the telescopic pressure roller connecting rod.

[0019] As a further preferred embodiment of the present application, the connecting structure between the telescopic press roller connecting rod and the press roller has two structures, one of which is a press roller middle connecting structure, and the other is a press roller two-side connecting structure. When the press roller middle connecting structure is used, a connecting notch is formed in the middle of the press roller, and the telescopic press roller connecting rod is rotatably connected to the press roller shaft at the connecting notch through a bearing. When the press roller two-side connecting structure is used, the telescopic press roller connecting rod is connected to the press roller shaft on both sides through a bearing. The press roller middle connecting structure and the press roller two-side connecting structure are used alternately in the same correction process for the same piece of car plate.

[0020] When the press roller two-side connecting structure is used, there are places on both sides of the press roller that cannot be pressed. Therefore, the press roller middle connecting structure is designed so that there are no places on both sides of the press roller that cannot be pressed. However, there are still places in the middle of the press roller that cannot be pressed. Therefore, the two structures need to be used alternately to achieve overall flattening of the car plate.

[0021] As a further preferred embodiment of the present application, a vertical roller pressing blind area processing mechanism is also included. The vertical roller pressing blind area processing mechanism is a horizontal pressing plate that is horizontally pressed and fixed at the roller pressing blind area on the upper part of the inner wall of the car and the roller pressing blind area on the lower part of the inner wall after vertical roller pressing is completed.

[0022] Due to the defect of its own structure, the press roller has a certain curvature when it moves vertically. Therefore, there are places on the top and bottom of the inner wall of the car plate that cannot be pressed. In order to flatten these roller pressing blind areas, the vertical roller pressing blind area processing mechanism is provided. The horizontal pressing plate is horizontally pressed and fixed at the roller pressing blind area on the upper part of the inner wall of the car and the roller pressing blind area on the lower part of the inner wall after roller pressing is completed. This achieves the flattening of the roller pressing blind area through the continuous opposite pressure, making the flattening more comprehensive.

[0023] A method for flattening an elevator car plate using any one of the above elevator car plate flattening devices, comprising the following steps: A, stopping the elevator car at the bottom of the elevator shaft, first probing the car plate of the elevator car to find the surface to be corrected; B, then installing and fixing the car outer supporting mechanism outside the car plate of the elevator car to be corrected, and installing the car inner pressing mechanism in the elevator car; C, starting the horizontal press roller mechanism to make it move in the vertical direction, and achieving on-site correction of the elevator car plate through the cooperation of the horizontal press roller mechanism and the car plate supporting panel; D, after the preliminary correction is completed, removing the car inner pressing mechanism, then installing and fixing the correction maintenance plate in the car, which is tightly arranged against the car plate to be corrected; E, removing the correction maintenance plate and the car outer supporting mechanism after two days of maintenance.

[0024] The device can be used to carry out the on-site flattening operation of the elevator car plate, so that the maintenance cost is low, the device is convenient to reuse, the flattening effect is good, and the noise caused by the deformation of the car plate can be effectively solved.

[0025] Compared with the prior art, the present application can achieve at least one of the following beneficial effects:

[0026] 1. In the present application, an elevator car plate flattening device for elevator use is designed, which mainly consists of two parts. One part is arranged outside the car as a car outer supporting mechanism, which can provide a flat surface for the correction of the elevator plate. Then the car inner pressing mechanism, i.e. the horizontal pressure roller mechanism, can provide sufficient pressure for the flattening of the car plate. The above structure is simple and has high flattening efficiency. The use of the device in the present application for flattening the car plate can effectively reduce the maintenance cost of the elevator.

[0027] 2. The support frame in the present application can provide uniform support force for the car plate support panel to prevent the deformation of the car plate support panel due to excessive pressure of the horizontal pressure roller mechanism during the flattening process.

[0028] 3. The horizontal connecting plate is fixedly connected with the car by bolts. Such a connecting structure is simple and convenient for operation in the elevator shaft.

[0029] 4. In order to achieve the best flattening effect, the verticality of the car plate support panel needs to be checked by using a plummet. In this way, it can be ensured that the outer surface of the flattened car plate is vertically arranged rather than obliquely arranged.

[0030] 5. In addition to checking the verticality of the car plate support panel, the verticality of the surface of the support frame that provides support for the car plate support panel also needs to be checked. In this way, it can be ensured that the car plate support panel will not be inclined during the flattening process. Therefore, a sliding plummet needs to be designed to facilitate the detection of the verticality of different planes. After being adjusted to the detection position, the sliding plummet is tightly positioned by a screwing type sliding block positioning mechanism.

[0031] 6. After years of use, the inner wall of the elevator shaft is not flat. Therefore, the support length can be adjusted by the telescopic support rod. For example, when the inner wall of the elevator shaft at a certain position is recessed a little, the telescopic support rod at that position can be lengthened. When the inner wall of the elevator shaft at a certain position is protruding, the telescopic support rod at that position can be shortened. In this way, the panel support plate can be kept vertical to provide uniform support force for the car plate support panel.

[0032] 7. When using the horizontal pressure roller mechanism, first fix the screw-type electric slide rail in the car with bolts, and then install the push rod slider on the screw-type electric slide rail. In this way, the lifting and lowering of the push rod slider can be controlled by the screw on the screw-type electric slide rail. The screw-type electric slide rail is existing technology and will not be described in detail. The main structure is a slide rail with a screw groove in between. A screw is set in the screw groove along the direction of the slide rail. The screw is connected to the motor. The middle part of the screw is threadedly connected to the push rod slider. When the screw rotates, the push rod slider is limited by the slide rail, so it can only move up and down along the slide rail. When the push rod slider moves up and down along the screw-type electric slide rail, the pressure roller connected to the push rod slider through the telescopic pressure roller connecting rod also moves synchronously. The surface of the pressure roller contacts the inner surface of the car plate to complete the roller pressing leveling operation. The pressure applied by the pressure roller to the car plate is provided by the telescopic pressure roller connecting rod.

[0033] 8. When using a two-sided pressure roller connection structure, there will be areas that the pressure roller cannot reach on both sides. Therefore, a middle pressure roller connection structure was designed to eliminate areas that the pressure roller cannot reach on both sides. However, this structure will have areas that cannot be pressed down at the connection gap in the middle of the pressure roller. Therefore, the two structures need to be used alternately to fully flatten the car body.

[0034] 9. When the pressure roller moves vertically, due to its own structural defects, it has a curvature. Therefore, there will inevitably be areas that the pressure roller cannot reach at the top and bottom of the inner wall of the car. In order to level these blind spots, a vertical blind spot treatment mechanism is set up. After the roller pressing is completed, the transverse pressure plate is horizontally pressed and fixed at the blind spots of the upper and lower inner walls of the car. In this way, the leveling operation of the blind spots is achieved by maintaining the opposing pressure continuously, making the leveling more comprehensive.

[0035] 10. Using this device enables on-site leveling of elevator car panels, resulting in low maintenance costs, easy reuse, and good leveling effect, effectively solving the noise caused by car panel deformation. Attached Figure Description

[0047] Specific Implementation Example 1: Figure 1 , Figure 2 , Figure 3 , Figure 4 An elevator car panel leveling device is shown, comprising an external support mechanism and an internal pressure mechanism. The upper and lower ends of the external support mechanism are connected to the top and bottom surfaces of the car respectively via a horizontal connecting structure 1. The external support mechanism includes a car panel support panel 2 and a support frame 3. The inner surface of the car panel support panel 2 contacts the outer surface of the car panel to be leveled, while the outer surface of the car panel support panel 2 contacts the support frame 3. The other end of the support frame 3 is fixedly connected to the inner wall of the elevator shaft. The internal pressure mechanism includes a horizontal pressure roller mechanism 4, which is vertically movable inside the elevator car.

[0048] This solution designs an elevator car panel leveling device that can be used in elevator installations. Its structure mainly consists of two parts. One part is set outside the car as an external support mechanism, which provides a flat surface for the elevator panel leveling. Then, the internal pressure mechanism inside the car, namely the horizontal pressure roller mechanism, provides sufficient pressure to level the car panel. The flattening operation of the elevator car panel is achieved during its vertical rolling process. The above structure is simple and has high leveling efficiency. Using the device in this solution to level the car panel can effectively reduce the maintenance cost of the elevator.

[0049] The support frame in the solution can provide uniform support force for the car panel support panel, preventing deformation of the car panel support panel due to excessive pressure from the horizontal pressure roller mechanism during the leveling process.

[0050] Specific Embodiment 2: This embodiment further describes the horizontal connection structure 1 based on Specific Embodiment 1. The horizontal connection structure 1 is a horizontal connection plate, which is fixedly connected to the car by connecting bolts.

[0051] The horizontal connecting plate is fixedly connected to the car with bolts. This connection structure is simple and facilitates operation inside the elevator shaft.

[0052] Specific embodiment 3: This embodiment is based on specific embodiment 1, with the addition of a plumb bob 5 for checking verticality. The plumb bob 5 is located on the side of the horizontal connecting plate at the top of the car for checking verticality.

[0053] To achieve the best leveling effect, a plumb line should be used to check the verticality of the car panel support panel. This ensures that the outer surface of the leveled car panel is vertically oriented rather than obliquely oriented.

[0054] Specific Embodiment 4: This embodiment further describes the plumb bob 5 based on Specific Embodiment 3. The plumb bob 5 is slidably connected to the horizontal slide rail 6 fixed on the side of the horizontal connecting plate via the plumb bob slider 51. The top of the horizontal slide rail 6 is provided with a screw-on slider positioning mechanism 7. The lower end of the screw-on slider positioning mechanism 7 passes downward through the top of the horizontal slide rail 6 and contacts the top of the plumb bob slider 51 which is slidably engaged in the slide groove on the bottom surface of the horizontal slide rail 6.

[0055] In addition to checking the verticality of the car panel support panel, it is also necessary to check the verticality of the support frame surface that provides support to ensure that it will not tilt during the flattening process. Therefore, a sliding plumb bob needs to be designed to handle the verticality test of different planes. After adjusting to the part to be tested, it is pressed and positioned by a screw-type slider positioning mechanism.

[0056] Specific Embodiment 5: This embodiment further describes the support frame 3 based on Specific Embodiment 1. The support frame 3 includes a panel support plate 31 and a telescopic support rod 32. One side of the panel support plate 31 is in contact with the outer surface of the car panel support panel 2. The telescopic support rod 32 is evenly distributed on the other side of the panel support plate 31. The telescopic support rod 32 is arranged in a horizontal direction. The other end of the telescopic support rod 32 is threaded to the inner wall of the elevator shaft.

[0057] After years of use, the inner wall of the elevator shaft is not flat. Therefore, the support length can be adjusted in a targeted manner by using telescopic support rods. For example, if the inner wall of the elevator shaft is slightly concave at a certain position, the telescopic support rod at that position can be extended. Conversely, if the inner wall of the elevator shaft is convex at a certain position, the telescopic support rod at that position can be shortened. This ensures that the panel support plate remains vertical and provides uniform support force for the car panel support plate.

[0058] Specific Embodiment 6: This embodiment further describes the horizontal pressure roller mechanism 4 based on Specific Embodiment 1. The horizontal pressure roller mechanism 4 includes a screw-type electric slide rail 41, a push rod slider 42, a telescopic pressure roller connecting rod 43, and a pressure roller 44. The screw-type electric slide rail 41 is detachably fixed in the elevator car along the vertical direction. The push rod slider 42 is slidably disposed in the middle of the screw-type electric slide rail 41. The push rod slider 42 is rotatably connected to the screw of the screw-type electric slide rail 41. The telescopic pressure roller connecting rod 43 is horizontally disposed on the outer end face of the push rod slider 42. The outer end face of the push rod slider 42 faces the inner surface of the car panel at the front of the car to be corrected. The pressure roller 44 is connected to the other end of the telescopic pressure roller connecting rod 43.

[0059] When using the horizontal pressure roller mechanism, first, a screw-type electric slide rail is fixedly installed inside the car with bolts. Then, a push rod slider is installed on the screw-type electric slide rail. In this way, the lifting and lowering of the push rod slider can be controlled by the screw on the screw-type electric slide rail. The screw-type electric slide rail is existing technology and will not be elaborated further. The main structure is a slide rail with a screw groove in between. A screw is installed in the screw groove along the direction of the slide rail. The screw is connected to the motor, and the middle part of the screw is threadedly connected to the push rod slider. When the screw rotates, the push rod slider is limited by the slide rail, so it can only move up and down along the slide rail. When the push rod slider moves up and down along the screw-type electric slide rail, the pressure roller connected to the push rod slider through the telescopic pressure roller connecting rod also moves synchronously. The surface of the pressure roller contacts the inner surface of the car plate, completing the roller-type leveling operation. The pressure applied by the pressure roller to the car plate is provided by the telescopic pressure roller connecting rod.

[0060] Specific Embodiment 7: This embodiment further describes the connection structure between the telescopic pressure roller connecting rod 43 and the pressure roller 44 based on Specific Embodiment 6. There are two types of connection structures between the telescopic pressure roller connecting rod 43 and the pressure roller 44. One type is a pressure roller intermediate connection structure, and the other is a pressure roller two-sided connection structure. When the pressure roller intermediate connection structure is used, a connection notch 441 is opened in the middle of the pressure roller 44. The telescopic pressure roller connecting rod 43 is rotatably connected to the pressure roller shaft of the pressure roller 44 at the connection notch 441 through a bearing. When the pressure roller two-sided connection structure is used, the telescopic pressure roller connecting rod 43 is connected to both sides of the pressure roller shaft of the pressure roller 44 through a bearing. For the same car board in the same correction process, the pressure roller intermediate connection structure and the pressure roller two-sided connection structure are used alternately.

[0061] When using a two-sided pressure roller connection structure, there will be areas that the pressure roller cannot reach on both sides. Therefore, a middle-side pressure roller connection structure was designed to eliminate the areas that the pressure roller cannot reach on both sides. However, this structure will have areas that cannot be pressed down at the connection gap in the middle of the pressure roller. Therefore, the two structures need to be used alternately to fully flatten the car body.

[0062] Specific embodiment 8: This embodiment is based on specific embodiment 1 and adds a vertical roller pressing blind area treatment mechanism. The vertical roller pressing blind area treatment mechanism is a horizontal pressure plate. After the vertical roller pressing is completed, the horizontal pressure plate is horizontally pressed and fixed at the roller pressing blind area on the upper part of the inner wall of the car and the roller pressing blind area on the lower part of the inner wall.

[0063] When the pressure roller moves vertically, due to its inherent structural defects, it has a curvature. Therefore, there will inevitably be areas that the pressure roller cannot reach at the top and bottom of the inner wall of the car. In order to level these blind spots, a vertical blind spot treatment mechanism is set up. After the roller pressing is completed, the transverse pressure plate is horizontally pressed and fixed at the blind spots on the upper and lower parts of the inner wall of the car. In this way, the leveling operation of the blind spots is achieved by maintaining continuous opposing pressure, making the leveling more comprehensive.

[0064] Specific Embodiment 9: A method for leveling an elevator car panel using any of the above-mentioned elevator car panel leveling devices, comprising the following steps: A. Stopping the elevator car at the bottom of the elevator shaft, first probing the elevator car panel to identify the front side of the elevator car to be leveled; B. Then installing and fixing the external support mechanism on the outside of the car panel on the front side of the elevator car to be leveled; and installing the internal pressure mechanism inside the elevator car; C. Activating the horizontal pressure roller mechanism 4 to enable it to move in the vertical direction, and achieving on-site leveling of the elevator car panel through the cooperation of the horizontal pressure roller mechanism 4 and the car panel support panel 2; D. After the initial leveling is completed, removing the internal pressure mechanism, and then installing and fixing the leveling maintenance plate inside the car, wherein the leveling maintenance plate is tightly pressed against the front side of the car panel to be leveled; E. After maintaining for two days, removing the leveling maintenance plate and the external support mechanism.

[0065] This device enables on-site leveling of elevator car panels, resulting in low maintenance costs, easy reuse, and good leveling effect, effectively solving the noise caused by car panel deformation.

[0066] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
