[0002] The sprocket traction villa elevator is a villa-specific elevator that uses a sprocket as a traction device. During the operation of this elevator, the rotation of the sprocket drives the elevator car up and down to achieve vertical transportation of passengers.

[0003] The working principle of the sprocket traction villa elevator is based on the traction mechanism. The traction machine in the elevator room is driven by an electric motor to rotate the sprocket. The chain is wound around the sprocket, and the two ends of the chain are connected to the car and the counterweight device respectively. When the sprocket rotates, the chain moves with it, thereby pulling the car and the counterweight to move relative to each other. That is, when the car rises, the counterweight drops; when the counterweight rises, the car drops.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1.

[0017] 2. During the lifting process of the elevator car, the slider is located in the middle of the slide groove with the support of the first spring and the second spring. When the elevator car vibrates and shakes during the lifting process, a relative displacement occurs between the fixed sleeve and the movable slide rod, causing the slider to slide in the slide groove; when the slider slides to the bottom of the slide groove, the slider compresses the first spring and stretches the second spring; when the slider slides to the notch of the slide groove, the slider compresses the second spring and stretches the first spring. The coordinated work of the first spring and the second spring makes the shock absorption effect of the guide wheel assembly more significant. Whether it is the impact force to the left or the right, it can be effectively absorbed and slowed down.

[0018] 3. When the elevator system needs maintenance or overhaul, the quantitative counterweight can be easily removed and reinstalled. This makes maintenance work simpler and faster, reducing maintenance costs and difficulties. At the same time, since the quantitative counterweight is independently set and can be increased or decreased or adjusted as needed, the weight distribution of the counterweight assembly can be adjusted according to actual conditions during the installation, commissioning or maintenance of the elevator to meet different operating requirements.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figures 1 to 10 As shown, a sprocket traction villa elevator comprises an elevator shaft, an elevator car body 1, a track guide mechanism 2 and a sprocket traction mechanism 3, the track guide mechanism 2 comprises a first guide rail 21 and a second guide rail 22, the first guide rail 21 and the second guide rail 22 are arranged in the elevator shaft in a vertical state, the top and the bottom of the elevator car body 1 are fixedly provided with a rotating bracket 11, the rotating bracket 11 is fixedly provided with a guide wheel assembly 12 that is slidably matched with the first guide rail 21, and the guide wheel assembly 12 comprises a fixed sleeve 13, a movable slide Rod 14, guide wheel bracket 15, rotating wheel 16 and elastic member, the fixed sleeve 13 is fixedly connected to the rotating bracket 11, one end of the movable slide rod 14 is slidingly connected to the fixed sleeve 13, the other end of the movable slide rod 14 is fixedly connected to the guide wheel bracket 15, the rotating wheel 16 is rotationally connected to the guide wheel bracket 15, and the rotating wheel 16 touches the first guide rail 21, the elastic member is fixedly arranged in the fixed sleeve 13, one end of the elastic member is fixedly connected to the fixed sleeve 13, and the other end of the elastic member is fixedly connected to the movable slide rod 14.

[0035] The sprocket traction mechanism 3 includes a derrick 31, a counterweight assembly 32, a traction machine 33, a sprocket 34, a chain 35 and a control terminal 36. The derrick 31 is vertically arranged in the elevator shaft, the counterweight assembly 32 is slidably connected to the second guide rail 22, the traction machine 33 and the control terminal 36 are fixedly arranged on the top of the derrick 31, and the traction machine 33 is electrically connected to the control terminal 36, the sprocket 34 is coaxially fixedly connected to the output end of the traction machine 33, and the two ends of the chain 35 are respectively connected to the counterweight assembly 32 and the elevator car body 1.

[0036] Specifically, the elevator shaft vertically passes through at least two floors in the building, the top of the well frame 31 is fixedly connected to the ceiling of the top floor, and the bottom of the well frame 31 is fixedly connected to the floor of the bottom floor. The outside of the well frame 31 is provided with operation buttons corresponding to each floor, and the inside of the elevator car 1 is provided with control buttons corresponding to each floor. The operation buttons and the control buttons are electrically connected to the control terminal 36.

[0037] When the passenger issues an instruction to the control terminal 36 through the operation button and the control button, the control terminal 36 determines the running direction and the stopping floor of the elevator according to the instruction. The control terminal 36 drives the traction machine 33, so that the sprocket 34 rotates, and the chain 35 moves accordingly, thereby pulling the elevator car body 1 and the counterweight assembly 32 to move relative to each other. That is, when the elevator car body 1 rises, the counterweight assembly 32 falls; when the counterweight assembly 32 rises, the elevator car body 1 falls.

[0038] During the lifting and lowering process of the elevator car 1, the counterweight assembly 32 slides up and down along the second guide rail 22, and the elevator car 1 passes through and the guide wheel assembly 12 on the top and bottom rotating brackets 11 slides up and down along the first guide rail 21. At this time, the rotating wheel 16 rolls on the first guide rail 21.

[0039] When the elevator car body 1 vibrates and shakes during the lifting process, a relative displacement occurs between the fixed sleeve 13 and the movable slide rod 14, which squeezes the elastic part in the fixed sleeve 13 and causes the elastic part to deform, thereby absorbing the vibration and shaking during the operation of the elevator, effectively reducing the shaking of the elevator car body 1 during the lifting process, and improving the riding comfort and safety of passengers.

[0040] refer to Figure 6 , Figure 8 and Fig.10 As shown, in some specific embodiments, the elastic member includes a first spring 17 and a second spring 18, a slide groove 19 is provided in the fixed sleeve 13, a slider 110 slidably matched with the slide groove 19 is fixedly provided at one end of the movable slide rod 14, the first spring 17 is arranged between the bottom of the slide groove 19 and the slider 110, one end of the first spring 17 is fixedly connected to the bottom of the slide groove 19, and the other end of the first spring 17 is fixedly connected to the slider 110. The second spring 18 is arranged between the notch of the slide groove 19 and the slider 110, one end of the second spring 18 is fixedly connected to the notch of the slide groove 19, and the other end of the second spring 18 is fixedly connected to the slider 110.

[0041] During the lifting process of the elevator car body 1, the slider 110 is located in the middle of the slide groove 19 under the support of the first spring 17 and the second spring 18. When the elevator car body 1 vibrates and shakes during the lifting process, a relative displacement occurs between the fixed sleeve 13 and the movable slide bar 14, causing the slider 110 to slide in the slide groove 19; when the slider 110 slides to the bottom of the slide groove 19, the slider 110 compresses the first spring 17 and stretches the second spring 18; when the slider 110 slides to the notch of the slide groove 19, the slider 110 compresses the second spring 18 and stretches the first spring 17. The coordinated work of the first spring 17 and the second spring 18 makes the shock absorption effect of the guide wheel assembly 12 more significant. Whether it is the impact force to the left or the right, it can be effectively absorbed and slowed down.

[0042] refer to Figure 6 , Figure 8 and Fig.10 As shown, in some specific embodiments, grooves are provided on the inner wall of the slot of the slide groove 19 and the outer wall of the slider 110, and balls 111 are provided in the grooves to roll with the grooves.

[0043] When the elevator car body 1 vibrates and shakes during the lifting process, causing the slider 110 to slide in the slide groove 19, the ball bearings 111 at the notch of the slide groove 19 roll, reducing the friction between the fixed sleeve 13 and the outer wall of the movable slide rod 14, and the ball bearings 111 on the outer wall of the slider 110 roll, reducing the friction between the slider 110 and the inner wall of the slide groove 19, reducing the heat and wear caused by friction, thereby extending the service life of the guide wheel assembly 12. At the same time, rolling friction generates less noise than sliding friction. Therefore, it also helps to reduce the noise level during the operation of the elevator and improve the riding experience of passengers.

[0044] refer to Figure 3 As shown, in some specific embodiments, at least two first guide rails 21 are provided and distributed in pairs in the elevator shaft, and guide wheel assemblies 12 that slide with the corresponding first guide rails 21 are fixedly provided on the mounting brackets at the top and bottom of the elevator car body 1.

[0045] By increasing the number of first guide rails 21 and distributing them in pairs, the elevator car body 1 is supported more evenly and stably during the lifting process, which helps to reduce the deviation and shaking of the elevator car body 1 during high-speed or long-term operation, and improves the overall stability of the elevator.

[0046] refer to Figures 4 to 10As shown, in some specific embodiments, the first guide rail 21 is provided with a plurality of mating surfaces, which are respectively a first mating surface 23, a second mating surface 24 and a third mating surface 25, wherein the first mating surface 23 and the third mating surface 25 are located on both sides of the first guide rail 21, and the second mating surface 24 is located between the first mating surface 23 and the third mating surface 25, and a plurality of guide wheel assemblies 12 are provided, and they are slidably matched with the corresponding mating surfaces respectively.

[0047] By increasing the number of matching surfaces of the first guide rail 21 and equipping each matching surface with a corresponding guide wheel assembly 12, the elevator car body 1 is supported more comprehensively and stably during the lifting process. This allows the elevator car body 1 to balance and offset forces and moments in different directions through the sliding cooperation between multiple guide wheel assemblies 12 and corresponding matching surfaces, thereby further reducing the shaking and deviation of the elevator car body 1 and improving the overall stability.

[0048] refer to Figures 4 to 10 As shown, in some specific embodiments, at least two guide wheel assemblies 12 are fixedly provided on the top and bottom mounting brackets of the elevator car body 1, and each guide wheel assembly 12 is slidably connected to the corresponding second mating surface 24.

[0049] When the elevator car body 1 encounters vibration or shaking during the lifting process, multiple guide wheel assemblies 12 can interact with the second matching surface 24 at the same time to absorb and reduce the impact force. This decentralized shock absorption mechanism makes the shock absorption effect more significant, effectively reduces the shaking amplitude of the elevator car body 1, and improves the riding comfort and safety of passengers.

[0050] refer to Figures 4 to 10 As shown, in some specific embodiments, at least two guide wheel assemblies 12 are fixedly provided on the top and bottom mounting brackets of the elevator car body 1, and each guide wheel assembly 12 is slidably connected with the corresponding first mating surface 23 and the third mating surface 25.

[0051] When the elevator car body 1 encounters vibration or shaking during the lifting process, multiple guide wheel assemblies 12 can simultaneously contact and interact with the first mating surface 23 and the third mating surface 25. Such dispersed contact points make the shock absorption effect more uniform and significant, further effectively reducing the shaking and vibration of the elevator car body 1 and improving the riding comfort of passengers.

[0052] refer to Figure 2 As shown, in some specific embodiments, the counterweight assembly 32 includes a lifting counterweight frame 37 and a quantitative counterweight block 38. The lifting counterweight frame 37 is slidably connected to the second guide rail 22. A plurality of quantitative counterweight blocks 38 are provided and are stacked in sequence in the lifting counterweight frame 37.

[0053] When the elevator system needs maintenance or overhaul, the quantitative counterweight block 38 can be easily removed and reinstalled. This makes maintenance work simpler and faster, and reduces maintenance costs and difficulties. At the same time, since the quantitative counterweight block 38 is independently set and can be increased or decreased or adjusted in position as needed, the weight distribution of the counterweight assembly 32 can be adjusted according to actual conditions during the installation, commissioning or maintenance of the elevator to meet different operating requirements.

[0054] In order to facilitate the understanding of the embodiments of the present invention by those skilled in the art, the working principle of the embodiments of the present invention is now described in combination with specific application scenarios:

[0055] In actual use, the passenger selects the target floor on the operation button of any floor, or after entering the elevator car 1, selects the target floor through the control button in the elevator car 1. These operation buttons are electrically connected to the control terminal 36 to send instructions to the control terminal 36.

[0056] After receiving the instruction, the control terminal 36 calculates the direction in which the elevator needs to run and the floor at which it needs to stop based on the current position and operating status of the elevator car 1, and sends a control signal to the traction machine 33.

[0057] After receiving the control signal, the traction machine 33 starts to drive the sprocket 34 coaxially fixedly connected thereto to rotate. The rotation of the sprocket 34 in turn drives the chain 35 to move, and the two ends of the chain 35 are respectively connected to the elevator car body 1 and the counterweight assembly 32, so the movement of the chain 35 will pull the elevator car body 1 and the counterweight assembly 32 to move relative to each other.

[0058] Under the traction of the chain 35, when the elevator car body 1 rises, the counterweight assembly 32 falls to maintain the balance of the system; conversely, when the counterweight assembly 32 rises, the elevator car body 1 falls. This relative movement is achieved by the sliding cooperation of the elevator car body 1 and the counterweight assembly 32 along the first guide rail 21 and the second guide rail 22 respectively.

[0059] During the lifting process of the elevator car 1, the rotating wheel 16 of the guide wheel assembly 12 rolls on the first guide rail 21 to ensure the smooth operation of the elevator car 1. When the elevator car 1 encounters vibration or shaking, a relative displacement occurs between the fixed sleeve 13 and the movable slide bar 14, squeezing or stretching the first spring 17 and the second spring 18, thereby absorbing and slowing down the vibration and shaking. This design significantly improves the riding comfort and safety of passengers.

[0060] The sliding cooperation of the multiple matching surfaces (the first matching surface 23, the second matching surface 24 and the third matching surface 25) of the first guide rail 21 and the guide wheel assembly 12 provides a more comprehensive and stable support for the elevator car body 1. This enables the elevator car body 1 to balance and offset the forces and moments in different directions through the sliding cooperation of the multiple guide wheel assemblies 12 and the corresponding matching surfaces, thereby reducing shaking and deviation.

[0061] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
