Description

Technical Field

[0001] This invention relates to the field of elevators, and more particularly to a continuously rolling upward automatic elevator for use with a half-story concrete staircase in a residential building. Background Technology

[0002] Currently, in domestic residential buildings, especially those with seven or fewer floors, a large number of older multi-story and mid-rise residential buildings are not equipped with traditional passenger elevators, and rely solely on half-floor cement staircases to meet residents' daily needs for going up and down stairs.

[0003] For the elderly, residents with children or tumors, climbing stairs is a serious burden. Traditional elevator renovations in old residential areas require damaging the main structure of the building, occupying a lot of space, with high renovation costs, long construction periods, and cannot be adapted to the narrow stairwell space of half a floor.

[0004] In the existing technology, one staircase renovation solution involves installing an equipment box on the side wall between two stair platforms. The equipment box contains a lifting mechanism that drives one stair platform to move up and down. When in use, the user steps on the stair platform, and the lifting mechanism raises and lowers the stair platform, thereby transferring the user from the lower stair platform to the upper stair platform.

[0005] The problem with this solution is that the stepping platform itself has a very limited area for users to stand on, making it easy for users to lose their balance. In addition, this solution can only transport one person at a time, and when multiple people are used, they must wait in line, resulting in low transfer efficiency. Summary of the Invention

[0006] The purpose of this invention is to provide a continuously rolling upward automatic elevator for use with half-floor concrete staircases in residential buildings, in order to solve the technical problems of limited standing area and inability to transport multiple people upwards at the same time in the prior art.

[0007] The technical solution of the present invention for a continuously rolling upward automatic elevator for use with a half-story concrete staircase in a residential building is as follows:

[0008] A continuous rolling upward automatic elevator for use with a half-story concrete staircase in a residential building includes an equipment box fixed to the side wall or handrail between two adjacent step platforms in the vertical direction. The equipment box is equipped with a lifting mechanism, which includes an upper drive wheel and a lower drive wheel with their rotation axes extending in the left-right direction. The ends of the upper and lower drive wheels away from the equipment box are suspended. The upper or lower drive wheel is driven by a drive motor. A circulating belt is wrapped around the suspended ends of the upper and lower drive wheels. The upper conveyor belt section of the circulating belt is for users to stand on. The equipment box is also rotatably equipped with multiple support rollers distributed along the conveying direction of the circulating belt. The outer roller surface of the support rollers is in rolling cooperation with the bottom support of the upper conveyor belt of the circulating belt.

[0009] Furthermore, the equipment box includes a left box wall and a right box wall arranged at intervals. The upper and lower drive wheels each include a drive wheel shaft with a rotation axis extending in the left-right direction. One end of the drive wheel shaft is a mounting end that is rotatably mounted on the left and right box walls via bearings, and the other end of the drive wheel shaft is an overhanging end. The upper and lower drive wheels also include pulleys mounted on the overhanging ends of the drive wheel shafts. A circulating belt is wound around the pulleys of the upper and lower drive wheels.

[0010] Furthermore, a roller bevel gear located between the left and right box walls is fixed on the transmission roller shaft of the upper transmission wheel. The axis of the drive motor shaft extends in the same direction as the conveying direction of the circulating belt. A motor shaft bevel gear that meshes with the roller bevel gear is fixed on the drive motor shaft.

[0011] Furthermore, the support roller includes a support roller shaft that is rotatably mounted on the left and right box walls via a bearing at one end. The end of the support roller shaft away from the equipment box is located on one side of the equipment box, and a support roller body is installed at this end. The outer roller surface of the support roller body achieves a rolling support with the bottom support of the upper conveyor belt of the circulating belt.

[0012] Furthermore, the continuously rolling upward automatic elevator also includes a control unit, the drive motor is a variable frequency motor electrically connected to the control unit, and an infrared photoelectric sensor or radar sensor for detecting users is provided at the lower end of the equipment box, the infrared photoelectric sensor or radar sensor is connected to the control unit for sampling.

[0013] Furthermore, the circulation belt is equipped with foot supports for users to step on, and the upper surface of the foot supports is a horizontally arranged foot surface.

[0014] Furthermore, the length of the equipment box is 2.5m to 2.7m, the thickness of the equipment box is 8cm to 9cm, and the width of the circulation belt is 28cm to 30cm.

[0015] The beneficial effects of this application are as follows: The automatic elevator of this invention can transport users from bottom to top, that is, transport the lower step platform of two adjacent step platforms to the toilet step platform in a vertical direction. In specific use, users only need to move from the lower step platform to the upper conveyor belt of the circulating belt, and then the circulating belt will lift the user to the upper step platform. The support rollers can support the upper conveyor belt to prevent it from collapsing or deforming. The circulating belt structure not only ensures smooth operation but also increases the area available for users to step on, making the lifting process more stable. In addition, it can also transport multiple people upwards simultaneously, improving the transport efficiency. Attached Figure Description

[0025] The features and performance of the present invention will be further described in detail below with reference to embodiments.

[0026] Example 1 of the present invention: A continuously rolling upward automatic elevator for use with a half-story concrete staircase in a residential building: Figures 1-4 As shown,

[0027] The device box 3 is used to fix itself to the wall side (or handrail) between two adjacent step platforms in the vertical direction. The device box 3 is inclined from bottom to top. The preferred length of the device box 3 is 2.6m, which meets the standard communication height of half-story cement staircases in residential buildings. It does not require segmented splicing. A single set of equipment can completely cover the entire upward journey of half-story staircases, ensuring the integrity of continuous operation. It can be adapted to the longitudinal space of most residential half-story staircases in China. It does not require additional customization according to the floor height and has good versatility.

[0028] The overall thickness of the equipment box 3 is preferably 9cm to minimize the impact on the stairwell space. When in use, the equipment box 3 can be fixed to the wall with expansion bolts.

[0029] The equipment box 3 includes a left box wall 12 and a right box wall 13 spaced apart from each other, and the equipment box 3 also includes a surrounding wall connecting the left box wall 12 and the right box wall 13.

[0030] The equipment box 3 is equipped with a lifting mechanism, which includes an upper drive wheel 7 and a lower drive wheel 6 whose rotation axis extends in the left-right direction. The ends of the upper drive wheel 7 and the lower drive wheel 6 away from the equipment box 3 are suspended. The upper drive wheel 7 (or the lower drive wheel 6) is driven by a drive motor 16. A circulating belt 2 is wrapped around the suspended ends of the upper drive wheel 7 and the lower drive wheel 6. The circulating belt 2 located above the upper drive wheel 7 and the lower drive wheel 6 is called the upper conveyor belt section, and the circulating belt 2 located below the upper drive wheel 7 and the lower drive wheel 6 is called the lower conveyor belt section. The upper conveyor belt section of the circulating belt 2 is provided for the user to stand on. The equipment box 3 is also rotatably equipped with multiple support rollers 9 distributed along the conveying direction of the circulating belt 2. The outer roller surface of the support rollers 9 rolls in cooperation with the bottom support of the upper conveyor belt of the circulating belt 2.

[0031] In this embodiment, both the upper drive wheel 7 and the lower drive wheel 6 include a drive roller shaft 8 whose rotation axis extends in the left-right direction. The right end of the drive roller shaft 8 is a mounting end that is rotatably mounted on the left side box wall 12 and the right side box wall 13 via bearings. The left end of the drive roller shaft 8 is an overhanging end that extends to the left side of the equipment box 3. The upper drive wheel 7 and the lower drive wheel 6 also include pulleys 18 that are fixedly mounted on the overhanging end of the drive roller shaft 8. The circulating belt 2 is a synchronous belt that is synchronously connected to the corresponding pulley 18.

[0032] A roller bevel gear 14 is fixed on the transmission roller shaft 8 of the upper transmission wheel 7, located between the left box wall 12 and the right box wall 13. The axis of the motor shaft of the drive motor 16 extends in the same direction as the conveying direction of the circulating belt 2. A motor shaft bevel gear 15 is fixed on the motor shaft of the drive motor 16, meshing with the roller bevel gear 14. In this embodiment, the continuously rolling upward automatic elevator also includes a control unit. The drive motor 16 is a variable frequency motor electrically connected to the control unit. A radar sensor 11 (or infrared photoelectric sensor 11) for detecting users is provided at the lower end of the equipment box 3. The radar sensor 11 (or infrared photoelectric sensor 11) is connected to the control unit for sampling. The drive motor 16 and the control unit can be directly connected to the mains power of the corridor.

[0033] The radar sensor 11 detects moving objects by emitting microwaves. When the user does not step on the recirculating belt 2, the control unit controls the drive motor 16 to rotate at a low speed of 20~30 (e.g., 0.15m / s). When the user steps on the recirculating belt 2, the radar sensor 11 detects the moving object, and the control unit controls the drive motor 16 to accelerate.

[0034] In this embodiment, the support roller 9 includes a support roller shaft 10, one end of which is rotatably mounted on the left side box wall 12 and the right side box wall 13 via bearings. The end of the support roller shaft 10 away from the equipment box 3 is located on the left side of the equipment box 3, and a support roller body 17 is installed at this end. That is, the support roller body 17 is located on the left side of the equipment box 3, and the outer roller surface of the support roller body 17 achieves rolling cooperation with the bottom support of the upper conveyor belt of the circulating belt 2. The entire circulating belt 2 is also located on the left side of the equipment box 3, and the width of the circulating belt 2 is preferably 29cm to minimize the spatial impact on other areas of the step 1.

[0035] Support plates 21 are provided on the upper and lower sides of this set of support rollers 17. The right end of the support plate 21 is fixed to the equipment box 3. The support plate 21 is an inclined plate structure with the same inclination as the circulating belt 2. The upper plate surface of the support plate 21 slides and contacts the bottom of the upper conveyor belt of the circulating belt 2 to prevent the user from collapsing at this position.

[0036] In use, the elevator moves from the lower step platform 5 to the bottom right end of the circulating belt 2, and then, under the action of the circulating belt 2, is conveyed to the upper step platform 4. It is very practical and convenient. This equipment is not intended for transporting people from top to bottom, as going upstairs is more tiring than going downstairs. The entire device occupies little space and requires no significant damage to the building structure. It is low-cost, safe, and completely solves the core problems of difficult elevator installation and inconvenient access in existing multi-story residential buildings in China.

[0037] In other embodiments of the present invention, a handrail can also be fixed on the wall facade on the upper side of the equipment box 3, so that the user can hold it when the circulating belt 2 is conveyed from bottom to top, thereby improving the stability of the conveying process.

[0038] Embodiment 2 of the present invention is a continuous rolling upward automatic elevator for a half-story cement staircase in a residential building. As shown in Figure 5, Embodiment 2 differs from Embodiment 1 in that, in Embodiment 1, the stepping surface of the circulating belt 2 is an inclined plane consistent with the conveying direction of the circulating belt 2. For some users who cannot stand on an inclined plane, in this invention, the circulating belt 2 is provided with stepping supports 19 for users to step on. The upper end surface of the stepping support 19 is a horizontally arranged stepping surface 20. The horizontally arranged stepping surface 20 is more conducive to users standing. The circulating belt 2 between adjacent stepping supports 19 is still an inclined plane. Of course, users can also stand on one stepping support 19 with one foot and the other foot on the inclined plane between the stepping supports 19.

[0039] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. The scope of patent protection of the present invention shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present invention shall also be included within the scope of protection of the present invention.
