Description

Technical Field

[0001] The utility model belongs to the field of elevator structures, in particular to a villa elevator driven by a steel belt. Background Art

[0002] In order to further save the effort of going up and down the stairs and facilitate the carrying of heavy objects up and down the stairs, in addition to installing ordinary stairs, existing villas generally also install vertical elevators; most of the existing villa elevators use steel belt traction instead of wire rope traction. Steel belts have many advantages over steel ropes: 1. No lubricating oil is required between the steel belt and the traction pulley of the motor, resulting in low friction and noise, and reduced vibration of the car; 2. There is no complicated wire rope winding design, and the size of the traction motor is reduced, resulting in a compact structure; 3. The weight of the steel belt is about 20% lighter than that of the wire rope, and the contact area between the steel belt and the traction shaft is larger, resulting in higher lifting efficiency and lower energy consumption.

[0003] However, the steel belt also has disadvantages during use: for example, the change in the tension angle during the winding process can easily cause the car to be in an unstable state, making it easy for passengers to feel a slight shaking of the car, resulting in a poor user experience. Utility Model Content

[0004] In view of this, the purpose of the present utility model is to provide a villa elevator driven by a steel belt to solve the technical problem in the prior art that the car is easily placed in an unstable state due to changes in the tension angle of the steel belt during the winding process.

DETAILED DESCRIPTION

[0043] The following is a detailed description of a steel belt driven villa elevator of the present invention in conjunction with the accompanying drawings and specific embodiments:

[0044] like Figure 1 As shown in the figure, a steel belt driven villa elevator of the present invention includes a hoistway support 1 arranged in the hoistway and a car 2 guided vertically relative to the hoistway support 1. The hoistway support 1 includes a bottom plate, support columns 15 fixed to the bottom plate, and a top plate 4 fixed to the top of the support columns 15. Reinforcement plates are also fixed between the support columns 15 to increase the structural strength of the hoistway support 1.

[0045] A driving structure and a transmission structure connected to the driving structure are fixed on the top plate 4 of the shaft support 1. In this embodiment, the driving structure is a driving motor 5. In this embodiment, the transmission structure is a transmission shaft 6 connected to the output shaft of the driving motor 5. The transmission shaft 6 extends in the left and right directions. A driving roller 7 is fixed on the transmission shaft 6. The driving motor 5 drives the rotating shaft of the transmission shaft 6, thereby rotating the driving roller 7 on the transmission shaft 6.

[0046] A steel belt 9 is provided between the drive roller 7 and the car 2. One end of the steel belt 9 is fixed relative to the car 2, and the other end of the steel belt 9 is wound around the drive roller 7. In this embodiment, a clearance hole for the steel belt to pass through is provided on the top plate 4 of the hoistway support 1. Baffles are provided on the left and right sides of the drive roller 7 to limit the steel belt 9 in the left and right directions, thereby ensuring that the steel belt 9 is more neatly wound around the drive roller 7.

[0047] In this embodiment, two transmission shafts 6 are arranged at intervals in front and back, and a drive motor 5 is correspondingly provided at the end of each transmission shaft 6. In this embodiment, the two drive motors 5 work synchronously; two drive rollers 7 are arranged at intervals in the left and right on each transmission shaft 6, thereby forming four steel belts 9 between the car 2 and the drive rollers 7, and the steel belts 9 are arranged at the four corners of the top of the car 2, so that during the winding or unwinding process of the steel belts 9, the car 2 can rise or fall stably.

[0048] A rectangular frame 8 is fixed to the upper portion of the shaft support 1. That is, the rectangular frame 8 is disposed below the top plate 4. The rectangular frame 8 includes a left frame plate 18 and a right frame plate 19 spaced apart from each other on the left and right sides, and also includes a front frame plate 20 and a rear frame plate spaced apart from each other on the front and back sides. A limiting structure is provided on the rectangular frame 8. In this embodiment, two sets of limiting structures are spaced apart from each other on the rectangular frame 8, and the two sets of limiting structures are symmetrically arranged on the front and back sides.

[0049] The limiting structure includes a fixed shaft 21 fixed between the left frame plate 18 and the right frame plate 19 of the rectangular frame 8. Two first rotating rollers 23 are rotatably mounted on the fixed shaft 21. The structure of the first rotating rollers 23 and the principle of their rotation relative to the fixed shaft 21 are prior art and will not be described in detail here. The limiting structure also includes a movable shaft 22 that is adjustable in the front-to-back direction relative to the rectangular frame 8. Two second rotating rollers 24 are rotatably mounted on the movable shaft 22. The structure of the second rotating rollers 24 and the principle of their rotation relative to the movable shaft 22 are prior art and will not be described in detail here. The second rotating rollers 24 are arranged in a corresponding manner with the first rotating rollers 23 in the front-to-back direction, so that the first rotating rollers 23 and the second rotating rollers 24 form a guide gap in the front-to-back direction for the steel strip 9 to pass through.

[0050] In this embodiment, the left frame plate 18 and the right frame plate 19 are symmetrically provided with guide holes 26 extending along the front-to-back direction, and guide blocks 27 are fixed at the left and right ends of the movable shaft 22. In this embodiment, threaded sections are provided at the left and right ends of the movable shaft 22, and the movable shaft 22 passes through the guide blocks 27, and the guide blocks 27 are fixedly connected relative to the movable shaft 22 through gaskets and nuts.

[0051] The guide block 27 is slidingly fitted relative to the guide hole 26. In this embodiment, the frame plate forms an upper plate body 28 on the upper side of the guide hole 26, and the frame plate forms a lower plate body 29 on the lower side of the guide hole 26. The upper surface of the guide block 27 is provided with an upper groove 30 with an opening facing upward, and the upper plate body 28 extends into the upper groove 30 so that the upper groove 30 and the upper plate body 28 are guided and fitted; the lower surface of the guide block 27 is provided with a lower groove 31 with an opening facing downward, and the lower plate body 29 extends into the lower groove 31 so that the lower groove 31 and the lower plate body 29 are guided and fitted.

[0052] A telescopic structure is provided on the front frame plate 20 corresponding to the guide hole 26. The telescopic end of the telescopic structure extends into the guide hole 26 and is fixedly connected to the guide block 27. In this embodiment, the telescopic structure is a telescopic hydraulic cylinder 25. The hydraulic cylinder 25 extends and pushes the movable shaft 22, causing the movable shaft 22 to move along the guide hole 26 toward the fixed shaft 21, thereby moving the second rotating roller 24 closer to the first rotating roller 23, so that the first rotating roller 23 and the second rotating roller 24 jointly form a guide gap for the steel strip 9 to pass through.

[0053] The car 2 is disposed between the support columns 15 in the left-right direction, with a guide structure disposed between the car 2 and the support columns 15. In this embodiment, guide grooves 16 are fixed to the support columns 15 in the vertical direction, and guide members 17 are fixed to the car 2 to slide in and out of the guide grooves 16. The guide grooves 16 include front and rear guide plates fixed to the support columns 15, spaced apart from each other. The front and rear guide plates together form the guide grooves 16. The provision of the guide structure enables the support columns 15 to limit the relative position of the car 2, further reducing the impact of the winding of the steel belt 9 on the car 2.

[0054] A buffer structure is provided at the bottom of the car 2, comprising a buffer plate 10 spaced below the car bottom 3 and a buffer assembly 11 provided between the car bottom 3 and the buffer plate 10.
