Abstract
Description
Technical Field
[0001] The invention relates to the field of plate leveling equipment, in particular to an elevator car plate leveling device. Background Art
[0002] The elevator car is an enclosed box structure that carries passengers or cargo in the elevator system. It is the core component of the elevator and is in direct contact with the user. Its design, size, material and function are directly related to the safety, comfort and efficiency of the elevator.
[0003] The main structure of the elevator car is the car frame, car roof, car bottom, car board and car door. The car frame is the main frame structure made of metal profiles welded or bolted together, which is used to support the car body and other components and bear all loads. The car roof and car bottom are respectively set at the top and bottom of the car frame, and the car board is set around the car frame as a panel. Abnormal noises often occur during the operation of the elevator. There are many reasons, usually involving friction, collision, looseness of mechanical parts or abnormal operation of electrical components. Among them, the more obvious one is the abnormal noise caused by friction and collision after deformation of the car board. Deformation is mainly caused by overloading, collision with foreign objects during lifting, aging of structural materials, etc. Although there are leveling devices for plates in the existing technology, they basically level the plates during the production process and there is no equipment that can be used for on-site leveling. Therefore, the deformation of the car plate can often only be dealt with by replacing the car plate. The maintenance cost is too high, and the implementation is relatively complicated and the construction period is long because it also involves disassembly, assembly and welding processes. In order to reduce this maintenance cost as much as possible, it is now necessary to invent a device that can level the car plate at the elevator use site. Summary of the Invention
[0004] The object of the present invention is to provide an elevator car plate leveling device to solve the problem that the existing elevator car plates are inconvenient to level during use.
[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: An elevator car plate leveling device includes an external car support mechanism and an internal car pressure mechanism, the upper and lower ends of the external car support mechanism are respectively connected to the top and bottom surfaces of the car through horizontal connecting structures, the external car support mechanism includes a car plate support panel and a support frame, the inner surface of the car plate support panel contacts the outer surface of the car plate at the front of the elevator car to be corrected, and the outer surface of the car plate support panel contacts the support frame, the other end of the support frame is fixedly connected to the inner wall of the elevator shaft, and the internal car pressure mechanism includes a horizontal pressure roller mechanism, which is movable in the vertical direction and is arranged inside the elevator car.
[0006] In this scheme, an elevator car plate leveling device that can be used in elevators is designed. Its specific structure is mainly composed of two parts. One part is arranged outside the car as an external car support mechanism, which can provide a flat surface for the correction of the elevator plate. Then the internal car pressure mechanism inside the car, that is, the horizontal pressure roller mechanism, can provide sufficient pressure for leveling the car plate. The elevator car plate can be flattened during the rolling process in the vertical direction. The above structure is simple and the leveling efficiency is high. Using the device in this scheme to level the car plate can effectively reduce the maintenance cost of the elevator.
[0007] The support frame in the solution can provide uniform support force for the car plate support panel, preventing it from being deformed due to excessive pressure from the horizontal roller mechanism during the leveling process.
[0008] As a further preferred embodiment of the present invention, the horizontal connection structure is a horizontal connection plate, and the horizontal connection plate is fixedly connected to the car via connecting bolts.
[0009] The horizontal connecting plate is fixedly connected to the car by bolts. This connection structure is simple and convenient for operation in the elevator shaft.
[0010] As a further preferred embodiment of the present invention, a plumb bob for checking verticality is provided on the side of the horizontal connecting plate located at the top of the car.
[0011] In order to achieve the best leveling effect, it is necessary to use a plumb line to check the verticality of the car plate support panel, so as to ensure that the outer surface of the leveled car plate is set vertically rather than diagonally.
[0012] As a further preference of the present invention, the plumb bob is slidably connected to the horizontal slide rail fixed on the side of the horizontal connecting plate through a plumb bob slider, and a screw-type slider positioning mechanism is provided on the top of the horizontal slide rail. The lower end of the screw-type slider positioning mechanism passes downward through the top of the horizontal slide rail and touches the top of the plumb bob slider which is slidably engaged in the slide groove on the bottom surface of the horizontal slide rail.
[0013] In addition to checking the verticality of the car plate support panel, it is also necessary to check the verticality of the support frame surface that provides support for it, so as to ensure that it will not tilt during the flattening process. Therefore, it is necessary to design a sliding plumb line to facilitate the verticality detection of different planes. After adjusting to the part to be tested, it is tightened and positioned through the tightening slider positioning mechanism.
[0014] As a further preferred embodiment of the present invention, the support frame includes a panel support plate and a telescopic support rod, one side of the panel support plate is in contact with the outer surface of the car plate support panel, and the telescopic support rod is evenly arranged on the other side of the panel support plate, the telescopic support rod is arranged in a horizontal direction, and the other end of the telescopic support rod is threadedly connected to the inner wall of the elevator shaft.
[0015] After years of use, the inner wall of the elevator shaft is not flat, so the telescopic support rod can be used to adjust the support length in a targeted manner. For example, when the inner wall of the elevator shaft at a certain position is concave, the telescopic support rod at that position can be extended, and when the inner wall of the elevator shaft at a certain position is convex, the telescopic support rod at that position can be shortened. In this way, the panel support plate can be kept vertical, providing uniform support force for the car plate support panel.
[0016] As a further preferred embodiment of the present invention, the horizontal pressure roller mechanism includes a screw-type electric slide rail, a push rod slider, a telescopic pressure roller connecting rod and a pressure roller, the screw-type electric slide rail is detachably fixed in the elevator car along the vertical direction, the push rod slider is slidingly arranged in the middle of the screw-type electric slide rail, the push rod slider is rotatably connected to the screw of the screw-type electric slide rail, the telescopic pressure roller connecting rod is horizontally arranged on the outer end face of the push rod slider, the outer end face of the push rod slider faces the inner surface of the car plate at the front face of the car to be corrected, and the pressure roller is connected to the other end of the telescopic pressure roller connecting rod.
[0017] When using the horizontal pressure roller mechanism, first fix the screw-type electric slide rail with bolts in the car, and then install the push rod slider on the screw-type electric slide rail, so that 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 a prior art and will not be described in detail. The main structure is a slide rail, which is provided with a screw rod groove. A screw rod is provided in the screw rod groove along the direction of the slide rail. The screw rod is connected to the motor, and the middle part of the screw rod is threadedly connected to the push rod slider. When the screw rod 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-type leveling operation. The pressure applied by the pressure roller to the car plate is provided by the telescopic pressure roller connecting rod.
[0018] As a further preference of the present invention, there are two types of connection structures between the telescopic pressure roller connecting rod and the pressure roller, one of which is a pressure roller middle connection structure, and the other is a pressure roller two-sided connection structure. When the pressure roller middle connection structure is adopted, a connection notch is opened in the middle of the pressure roller, and the telescopic pressure roller connecting rod is rotatably connected to the pressure roller shaft of the pressure roller at the connection notch through a bearing. When the pressure roller two-sided connection structure is adopted, the telescopic pressure roller connecting rod is connected to both sides of the pressure roller shaft of the pressure roller through bearings. During the same correction process of the same car plate, the pressure roller middle connection structure and the pressure roller two-sided connection structure are used alternately.
[0019] When using the roller-side connection structure, there will be places on both sides that the roller cannot press. Therefore, a roller-middle connection structure is designed, so that there will be no places on both sides that the roller cannot press. However, such a structure will have places that cannot be pressed at the connection notch in the middle of the roller. Therefore, the two structures need to be used alternately to fully flatten the car plate.
[0020] As a further preference of the present invention, it also includes a vertical rolling blind area processing mechanism, which is a horizontal pressure plate. After completing the vertical rolling, the horizontal pressure plate is horizontally pressed and fixed in the rolling blind area on the upper part of the inner wall of the car and the rolling blind area on the lower part of the inner wall.
[0021] When the pressure roller moves vertically, there is an arc due to its own structural defects. Therefore, there will be places at the top and bottom of the inner wall of the car plate that the pressure roller cannot reach. In order to level this part of the roller blind area, a vertical roller blind area processing mechanism is set up. After the rolling is completed, the transverse pressure plate is horizontally pressed and fixed on the roller blind area on the upper part of the inner wall of the car and the roller blind area on the lower part of the inner wall. In this way, the leveling operation of the roller blind area is achieved by continuously maintaining the opposite pressure, making the leveling more comprehensive.
[0022] A method for leveling an elevator car plate using any of the above-mentioned elevator car plate leveling devices comprises 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 out the front face of the elevator car to be corrected; B. then installing and fixing an external car support mechanism outside the car plate on the front face of the elevator car to be corrected; and entering the elevator car to install an internal car pressure mechanism; C. starting a horizontal pressure roller mechanism to enable it to move in a vertical direction, and achieving on-site correction of the elevator car plate through the cooperation of the horizontal pressure roller mechanism and the car plate support panel; D. after the preliminary correction is completed, removing the internal car pressure mechanism, and then installing and fixing a correction maintenance plate in the car, wherein the correction maintenance plate is tightly set against the car plate on the front face of the elevator car to be corrected; E. after maintaining for two days, removing the maintenance plate to be corrected and the external car support mechanism.
[0023] The device can be used to perform on-site leveling operations on elevator car panels, which reduces maintenance costs and is easy to reuse. The leveling effect is good and can effectively solve the noise caused by deformation of the car panels.
[0024] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects: 1. In this scheme, an elevator car plate leveling device that can be used in elevators is designed. Its specific structure mainly consists of two parts, one of which is an external car support mechanism arranged outside the car, which can provide a flat surface for the correction of the elevator plate. Then, the internal car pressure mechanism inside the car, that is, the horizontal pressure roller mechanism, can provide sufficient pressure for leveling the car plate. The elevator car plate can be flattened during the rolling process in the vertical direction. The above structure is simple and the leveling efficiency is high. Using the device in this scheme to level the car plate can effectively reduce the maintenance cost of the elevator.
[0025] 2. The support frame in the solution can provide uniform support force for the car plate support panel, preventing the car plate support panel from being deformed due to excessive pressure from the horizontal roller mechanism during the leveling process.
[0026] 3. The horizontal connecting plate is fixedly connected to the car by bolts. This connection structure is simple and convenient for operation in the elevator shaft.
[0027] 4. In order to achieve the best leveling effect, it is necessary to use a plumb line to check the verticality of the car plate support panel, so as to ensure that the outer surface of the leveled car plate is set vertically rather than diagonally.
[0028] 5. In addition to checking the verticality of the car plate support panel, it is also necessary to check the verticality of the support frame surface that provides support for it, so as to ensure that it will not tilt during the flattening process. Therefore, it is necessary to design a sliding plumb line to facilitate the verticality detection of different planes. After adjusting to the part to be tested, it is tightened and positioned through the tightening slider positioning mechanism.
[0029] 6. After years of use, the inner wall of the elevator shaft is not flat, so the telescopic support rod can be used to adjust the support length in a targeted manner. For example, when the inner wall of the elevator shaft at a certain position is concave, the telescopic support rod at that position can be extended, and when the inner wall of the elevator shaft at a certain position is convex, the telescopic support rod at that position can be shortened. In this way, the panel support plate can be kept vertical, providing uniform support force for the car plate support panel.
[0030] 7. When using the horizontal pressure roller mechanism, first fix the screw-type electric slide rail with bolts in the car, and then install the push rod slider on the screw-type electric slide rail, so that 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 a prior art and will not be described in detail. The main structure is a slide rail, which is provided with a screw rod groove. A screw rod is provided in the screw rod groove along the setting direction of the slide rail. The screw rod is connected to the motor, and the middle part of the screw rod is threadedly connected to the push rod slider. When the screw rod 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-type leveling operation. The pressure applied by the pressure roller to the car plate is provided by the telescopic pressure roller connecting rod.
[0031] 8. When the roller-side connection structure is adopted, there will be places on both sides that the roller cannot press. Therefore, a roller-middle connection structure is designed. In this way, there will be no places on both sides that the roller cannot press. However, such a structure will have places that cannot be pressed at the connection notch in the middle of the roller. Therefore, the two structures need to be used alternately to fully flatten the car plate.
[0032] 9. When the pressure roller moves vertically, there is an arc due to its own structural defects. Therefore, there will be places at the top and bottom of the inner wall of the car plate that the pressure roller cannot reach. In order to level this part of the roller blind area, a vertical roller blind area processing mechanism is set up. After the rolling is completed, the transverse pressure plate is horizontally pressed and fixed on the roller blind area on the upper part of the inner wall of the car and the roller blind area on the lower part of the inner wall. In this way, the leveling operation of the roller blind area is achieved by continuously maintaining the opposite pressure, making the leveling more comprehensive.
[0033] 10. The device can be used to perform on-site leveling of elevator car panels, which reduces maintenance costs and is easy to reuse. The leveling effect is good and can effectively solve the noise caused by deformation of the car panels. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] Specific embodiment 1: Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 An elevator car plate leveling device is shown, including an external car support mechanism and an internal car pressure mechanism, the upper and lower ends of the external car support mechanism are respectively connected to the top and bottom surfaces of the car through a horizontal connecting structure 1, the external car support mechanism includes a car plate support panel 2 and a support frame 3, the inner surface of the car plate support panel 2 is in contact with the outer surface of the car plate at the front of the elevator car to be corrected, and the outer surface of the car plate support panel 2 is in contact with the support frame 3, the other end of the support frame 3 is fixedly connected to the inner wall of the elevator shaft, and the internal car pressure mechanism includes a horizontal pressure roller mechanism 4, and the horizontal pressure roller mechanism 4 can be movably arranged in the vertical direction inside the elevator car.
[0046] In this solution, an elevator car plate leveling device that can be used in elevators is designed. Its specific structure is mainly composed of two parts. One part is arranged outside the car as an external car support mechanism, which can provide a flat surface for the correction of the elevator plate. Then the internal car pressure mechanism inside the car, that is, the horizontal pressure roller mechanism, can provide sufficient pressure for leveling the car plate. The elevator car plate can be flattened during the rolling process in the vertical direction. The above structure is simple and the leveling efficiency is high. Using the device in this solution to level the car plate can effectively reduce the maintenance cost of the elevator.
[0047] The support frame in the solution can provide uniform support force for the car plate support panel, preventing the car plate support panel from being deformed due to excessive pressure from the horizontal pressure roller mechanism during the leveling process.
[0048] Specific embodiment 2: This embodiment further illustrates 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 through connecting bolts.
[0049] The horizontal connecting plate is fixedly connected to the car by bolts. This connection structure is simple and convenient for operation in the elevator shaft.
[0050] Specific embodiment 3: This embodiment is based on specific embodiment 1 and is provided with a plumb bob 5 for checking verticality. A plumb bob 5 for checking verticality is provided on the side of the horizontal connecting plate at the top of the car.
[0051] In order to achieve the best leveling effect, it is necessary to use a plumb line to check the verticality of the car plate support panel, so as to ensure that the outer surface of the leveled car plate is set vertically rather than diagonally.
[0052] Specific embodiment 4: This embodiment further explains the plumb bob 5 on the basis of 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 through the plumb bob slider 51. The top of the horizontal slide rail 6 is provided with a screw-type slider positioning mechanism 7. The lower end of the screw-type slider positioning mechanism 7 passes downward through the top of the horizontal slide rail 6 and touches the top of the plumb bob slider 51 that is slidably engaged in the slide groove on the bottom surface of the horizontal slide rail 6.
[0053] In addition to checking the verticality of the car plate support panel, it is also necessary to check the verticality of the support frame surface that provides support for it, so as to ensure that it will not tilt during the flattening process. Therefore, it is necessary to design a sliding plumb line to facilitate the verticality detection of different planes. After adjusting to the part to be tested, it is tightened and positioned through the tightening slider positioning mechanism.
[0054] Specific embodiment 5: This embodiment further explains 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 plate support panel 2, and 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 the horizontal direction, and the other end of the telescopic support rod 32 is threadedly connected to the inner wall of the elevator shaft.
[0055] After years of use, the inner wall of the elevator shaft is not flat, so the telescopic support rod can be used to adjust the support length in a targeted manner. For example, when the inner wall of the elevator shaft at a certain position is concave, the telescopic support rod at that position can be extended, and when the inner wall of the elevator shaft at a certain position is convex, the telescopic support rod at that position can be shortened. In this way, the panel support plate can be kept vertical, providing uniform support force for the car plate support panel.
[0056] Specific embodiment 6: This embodiment further explains the horizontal pressure roller mechanism 4 based on specific embodiment 1, and the horizontal pressure roller mechanism 4 includes a screw-type electric slide 41, a push rod slider 42, a telescopic pressure roller connecting rod 43 and a pressure roller 44. The screw-type electric slide 41 is detachably fixed in the elevator car along the vertical direction, and the push rod slider 42 is slidingly set in the middle of the screw-type electric slide 41. The push rod slider 42 is rotatably connected to the screw of the screw-type electric slide 41, and the telescopic pressure roller connecting rod 43 is horizontally set 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 plate at the front side of the car to be corrected, and the pressure roller 44 is connected to the other end of the telescopic pressure roller connecting rod 43.
[0057] When using the horizontal pressure roller mechanism, first fix the screw-type electric slide rail with bolts in the car, and then install the push rod slider on the screw-type electric slide rail, so that 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 a prior art and will not be described in detail. The main structure is a slide rail, which is provided with a screw rod groove. A screw rod is provided in the screw rod groove along the direction of the slide rail. The screw rod is connected to the motor, and the middle part of the screw rod is threadedly connected to the push rod slider. When the screw rod 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-type leveling operation. The pressure applied by the pressure roller to the car plate is provided by the telescopic pressure roller connecting rod.
[0058] Specific embodiment 7: This embodiment further explains the connection structure between the telescopic pressure roller connecting rod 43 and the pressure roller 44 on the basis of specific embodiment 6. There are two types of connection structures between the telescopic pressure roller connecting rod 43 and the pressure roller 44, one of which is a pressure roller middle connection structure, and the other is a pressure roller two-sided connection structure. When the pressure roller middle connection structure is adopted, a connection notch 441 is opened in the middle of the pressure roller 44, and 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 adopted, the telescopic pressure roller connecting rod 43 is connected to both sides of the pressure roller shaft of the pressure roller 44 through bearings. During the same correction process of the same car plate, the pressure roller middle connection structure and the pressure roller two-sided connection structure are used alternately.
[0059] When using the roller-side connection structure, there will be places on both sides that the roller cannot press. Therefore, a roller-middle connection structure is designed, so that there will be no places on both sides that the roller cannot press. However, such a structure will have places that cannot be pressed at the connection notch in the middle of the roller. Therefore, the two structures need to be used alternately to fully flatten the car plate.
[0060] Specific embodiment 8: This embodiment is based on specific embodiment 1 and adds a vertical roller pressure blind area processing mechanism, and also includes a vertical roller pressure blind area processing mechanism. The vertical roller pressure blind area processing mechanism is a horizontal pressure plate. After completing the vertical rolling, the horizontal pressure plate is horizontally pressed and fixed in the roller pressure blind area on the upper part of the inner wall of the car and the roller pressure blind area on the lower part of the inner wall.
[0061] When the pressure roller moves vertically, there is an arc due to its own structural defects. Therefore, there will be places at the top and bottom of the inner wall of the car plate that the pressure roller cannot reach. In order to level this part of the roller blind area, a vertical roller blind area processing mechanism is set up. After the rolling is completed, the transverse pressure plate is horizontally pressed and fixed on the roller blind area on the upper part of the inner wall of the car and the roller blind area on the lower part of the inner wall. In this way, the leveling operation of the roller blind area is achieved by continuously maintaining the opposite pressure, making the leveling more comprehensive.

Stop the elevator car at the bottom of the elevator shaft, first explore the car plate of the elevator car, and find out the front face of the elevator car to be corrected; B. Then install and fix the car external support mechanism outside the car plate on the front face of the elevator car to be corrected; and enter the elevator car to install the car internal pressure mechanism; C. Start the horizontal pressure roller mechanism 4 so that it can move in the vertical direction, and realize on-site correction of the elevator car plate through the cooperation of the horizontal pressure roller mechanism 4 and the car plate support panel 2; D. After the preliminary correction is completed, remove the car internal pressure mechanism, and then install and fix a correction maintenance plate in the car, and the correction maintenance plate is tightly set against the car plate on the front face to be corrected; E. After maintaining for two days, remove the maintenance plate to be corrected and the car external support mechanism.
[0063] The device can be used to perform on-site leveling operations on elevator car panels, which reduces maintenance costs and is easy to reuse. The leveling effect is good and can effectively solve the noise caused by deformation of the car panels.
