AI Technical Summary
When the weight is uneven within the car of an existing vertical elevator, it causes the elevator car to become unbalanced, resulting in excessive pressure on the tracks and installation structure, which in turn accelerates damage.
The system employs a combination structure of a first guide wheel, a spring, and a second guide wheel. The spring's compression and contraction adjust the gap, ensuring that the first guide wheel contacts the guide rail. The second guide wheel assists in supporting the car's balance and prevents the first guide wheel from being excessively compressed.
It effectively maintains the balance of the car, reduces damage to the first guide wheel, extends its service life, and improves the stability and safety of elevator operation.

Abstract
Description
Technical Field
[0001] This application relates to the field of elevator technology, and in particular to a stable elevator self-balancing device. Background Technology
[0002] An elevator is a permanent transportation device that serves several specific floors within a building, with its car moving between at least two rigid guide rails perpendicular to the horizontal plane or at an angle of inclination less than 15° to the vertical. It is a fixed lifting device serving designated floors. A vertical elevator has a car that runs between at least two rigid guide rails that are vertical or at an inclination angle of less than 15°. The size and structure of the car facilitate passenger entry and exit or loading and unloading of goods.
[0003] Currently, vertical elevators require counterweights to maintain their balance during operation. However, uneven weight distribution within the car can cause imbalance, putting significant pressure on the tracks and installation structure during lifting and lowering. Over time, this can lead to accelerated damage to components. Therefore, a stable self-balancing device for elevators has been designed to address these issues. Utility Model Content
[0004] To address this problem, this application provides a stable elevator self-balancing device.
[0005] The stable elevator self-balancing device provided in this application adopts the following technical solution:
[0006] A stable elevator self-balancing device includes a car and a guide rail. Fixed blocks are installed on both sides of the upper and lower ends of the car. Mounting plates are fixedly connected to the front and rear parts of the fixed blocks. A mounting groove is opened on the side of the mounting plate near the guide rail, and a spring is fixedly connected in the middle of the mounting groove. A first mounting seat is fixedly connected to one side of the spring. A first guide wheel is rotatably installed on the side of the first mounting seat away from the inner wall of the mounting groove.
[0007] The No. 2 guide wheel is installed above and below the No. 1 guide wheel and is used to assist in the lifting and lowering of the car.
[0008] Preferably, the second guide wheel is rotatably mounted on the second mounting base, and one side of the second mounting base is fixedly connected to the inner wall of the mounting groove.
[0009] Preferably, a telescopic sleeve rod is installed on the side of the first mounting base away from the first guide wheel, and the side of the telescopic sleeve rod away from the first mounting base is fixedly connected to the inner wall of the mounting groove.
[0010] Preferably, a support block is also fixedly connected to the side of the fixed block near the guide rail, and an auxiliary wheel is rotatably mounted on one side of the support block, with the auxiliary wheel in contact with the guide rail.
[0011] Preferably, a limiting block is also fixedly installed on one side of the mounting plate, and a limiting slider is fixedly installed on one side of the limiting block.
[0012] In summary, this application includes the following beneficial technical effects:
[0013] In this invention, by using a first guide wheel, a first mounting base, and a spring, when the weight is uneven inside the car, the adjustable gap allows the first guide wheel to be compressed by the car's action, thus preventing excessive compression of the first guide wheel. Furthermore, the second guide wheel, located above and below the first guide wheel, will contact the guide rail. The two second guide wheels then assist the first guide wheel in supporting the car, ensuring the car's balance and preventing accelerated damage to the first guide wheel. Attached Figure Description

[0018] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0019] This application discloses a stable elevator self-balancing device. (Refer to...) Figure 1-3 A stable elevator self-balancing device includes a car 1 and a guide rail 2. Fixing blocks 3 are installed on both sides of the upper and lower ends of the car 1. Mounting plates 4 are fixedly connected to the front and rear parts of the fixing blocks 3. Mounting plates 4 have a mounting groove on the side near the guide rail 2, and a spring 5 is fixedly connected in the middle of the mounting groove. A first mounting seat 7 is fixedly connected to one side of the spring 5. A first guide wheel 8 is rotatably installed on the side of the first mounting seat 7 away from the inner wall of the mounting groove.
[0020] If the weight is uneven in the front and rear of the car 1, causing the car 1 to tilt slightly, the first guide wheel 8 in the fixed block 3 on one side will be driven to fit more closely to the side wall of the guide rail 2. This will cause the spring 5 on one side of the first guide wheel 8 to be compressed and contracted, thereby preventing the first guide wheel 8 on the tilted side from being excessively compressed.
[0021] The second guide wheel 10 is installed above and below the first guide wheel 8 to assist in the lifting and lowering of the car 1. The second guide wheel 10 is rotatably installed on the second mounting base 9, and one side of the second mounting base 9 is fixedly connected to the inner wall of the mounting groove.
[0022] The second guide wheel 10, located above and below the first guide wheel 8, will contact the guide rail 2. The two second guide wheels 10 will assist the first guide wheel 8 in supporting the car 1 and distributing the pressure on the first guide wheel 8, thereby ensuring the balance of the car 1 and preventing the first guide wheel 8 from being damaged prematurely.
[0023] By adopting the above technical solution, a telescopic sleeve rod 6 is installed on the side of the first mounting base 7 away from the first guide wheel 8. The side of the telescopic sleeve rod 6 away from the first mounting base 7 is fixedly connected to the inner wall of the mounting groove. The telescopic sleeve rod 6 is composed of a sleeve and a sleeve rod that are slidably connected. One end of the sleeve is fixedly connected to the first mounting base 7, and one end of the sleeve rod is fixedly connected to the inner wall of the mounting groove, which serves to limit the movement of the first mounting base 7 and ensure that the first guide wheel 8 installed at one end of the first mounting base 7 is always in contact with the guide rail 2.
[0024] By adopting the above technical solution, the fixed block 3 is also fixedly connected to the support block 11 on the side near the guide rail 2. An auxiliary wheel 12 is rotatably installed on one side of the support block 11. The auxiliary wheel 12 is in contact with the guide rail 2. The auxiliary wheel 12 is used to support the car 1 on both sides to ensure the stability of the car 1 when it is raised and lowered.
[0025] A limit block 13 is also fixedly installed on one side of the mounting plate 4, and a limit slider 14 is fixedly installed on one side of the limit block 13. The limit slider 14 is in contact with the side wall of the guide rail 2 and can slide on the guide rail 2 when the car 1 moves, so as to limit the connection between the car 1 and the guide rail 2 during operation.
[0026] The implementation principle of a stable elevator self-balancing device in this application embodiment is as follows: If the weight is uneven in the front and rear of the car 1, causing the car 1 to tilt partially, it will cause the first guide wheel 8 in the fixed block 3 on one side to fit more closely to the side wall of the guide rail 2. This will cause the spring 5 on one side of the first guide wheel 8 to be compressed and contracted, thereby preventing the first guide wheel 8 on the tilted side from being excessively compressed. At the same time, the second guide wheel 10 located above and below the first guide wheel 8 will contact the guide rail 2. The two second guide wheels 10 will assist the first guide wheel 8 in supporting the car 1 and distributing the pressure on the first guide wheel 8, thereby ensuring the balance of the car 1 and preventing the first guide wheel 8 from being damaged prematurely.
