Description

Technical Field

[0001] This invention relates to the field of elevator technology, and specifically to a steel belt traction type home elevator. Background Technology

[0002] With the advancement of urbanization and construction, and the continuous improvement of people's living standards, the market demand for home elevators is also constantly increasing. Currently, home platform elevators on the market are mainly divided into screw-driven and steel belt traction drive structures. Screw-driven home platform elevators have disadvantages such as slow operating speed, high noise, noticeable vibration, and high manufacturing costs. Meanwhile, most steel belt traction home platform elevators on the market currently use a traditional backpack-frame car and a linkage structure of safety brakes and speed governors. This structure is not compact, has low shaft space utilization, and its application range is limited. Summary of the Invention

[0003] In view of this, in order to solve the problems of the prior art, the present invention provides an improved steel belt traction elevator with a compact structure and high space utilization.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A steel belt traction elevator includes a traction machine, a counterweight assembly, a car assembly, a counterweight guide rail, a car guide rail, and a steel belt. The traction machine, counterweight assembly, counterweight guide rail, car guide rail, and steel belt are all located on one side of the car assembly. The steel belt is straddled on the traction machine, with one end of the steel belt connected to the counterweight assembly and the other end of the steel belt connected to the car assembly. The counterweight guide rail and the car guide rail are located directly below the traction machine and are located in the same vertical plane.

[0006] According to some preferred embodiments of the present invention, both the counterweight guide rail and the car guide rail include a fixing part and a guiding part, wherein the guiding parts of the counterweight guide rail and the car guide rail are located in the same vertical plane. The counterweight guide rail and the car guide rail are structurally similar, both being T-shaped guide rail structures. The guiding part is used for guiding the movement of the counterweight assembly or the car assembly, and the fixing part is used for fixing to a fixing frame, which is fixed to the hoistway, thereby fixing the guide rail. By setting the guiding parts of the counterweight guide rail and the car guide rail to be located in the same vertical plane, the structure is more compact, and the overall stability of the structure during movement is improved.

[0007] According to some preferred embodiments of the invention, the guide portions of the counterweight guide rails and car guide rails face opposite directions. Specifically, the guide portions of the two counterweight guide rails face inwards, i.e., towards the counterweight, allowing the counterweight assembly to move between the two counterweight guide rails; while the guide portions of the two car guide rails face outwards, resulting in a compact structure. Furthermore, the fixing portions of the same set of counterweight guide rails and car guide rails are close to each other, facilitating installation and fixation using the same mounting bracket.

[0008] According to some preferred embodiments of the present invention, the counterweight assembly includes a counterweight frame slidably disposed along the counterweight guide rail and a counterweight disposed within the counterweight frame; the car assembly includes a car frame, the car frame including a car floor and uprights, the uprights being slidably disposed along the car guide rail. Two uprights are arranged opposite each other, perpendicular to the car floor, and fixed to the side of the car floor near the counterweight.

[0009] According to some preferred embodiments of the invention, the uprights are located outside the car guide rails, and the counterweight assembly moves within the vertical space formed by the uprights on both sides. That is, the counterweight assembly and the two car guide rails are located within the space formed by the two uprights, and the inner sides of the uprights match and guide the car guide rails, resulting in a compact structure.

[0010] According to some preferred embodiments of the present invention, a speed detection mechanism, a safety clamp, and a control module are included. The safety clamp is disposed on the upright plate at a position corresponding to the car guide rail. The control module controls the safety clamp to actuate based on the speed feedback from the speed detection mechanism. Specifically, a speed threshold can be preset within the control module. When the control module receives a speed of the car exceeding the speed threshold, it controls the safety clamp to actuate, thereby slowing down or stopping the car. The safety clamp is an electronic safety clamp.

[0011] According to some preferred embodiments of the present invention, the speed detection mechanism includes a magnetic head and a magnetic tape, the magnetic head being disposed on the vertical plate, and the magnetic tape being disposed within the shaft corresponding to the magnetic head. Speed ​​measurement is achieved through the cooperation of the magnetic head and the magnetic tape, and the measured speed is fed back to the control module.

[0012] According to some preferred embodiments of the invention, the safety clamp is disposed on the side of the vertical plate near the car guide rail, and the magnetic head is disposed on the side of the vertical plate away from the car guide rail. Since the car guide rail is disposed on the inner side of the vertical plate, the safety clamp is disposed on the inner side of the vertical plate to cooperate with the car guide rail to achieve operation. The magnetic tape is disposed in the space between the outer side of the vertical plate and the hoistway, so the magnetic head is disposed on the outer side of the vertical plate to cooperate with the magnetic tape to achieve speed measurement.

[0013] According to some preferred embodiments of the present invention, one end of the steel strip is fixed to the upper end of the counterweight frame; a reinforcing plate is provided between the lower parts of the two uprights, and a connecting plate is provided on the reinforcing plate, with the other end of the steel strip fixed to the connecting plate. That is, the traction ratio of the elevator in the present invention is 1:1.

[0014] According to some preferred embodiments of the invention, the extension direction of the traction sheave axis in the traction machine is parallel to or lies within the plane containing the counterweight guide rail or the car guide rail. That is, the vertical plane containing the counterweight guide rail and the car guide rail is located between the steel strips on both sides.

[0015] According to some preferred embodiments of the present invention, a notch is provided on the side of the counterweight near the car, and the steel strip passes through the notch. Through these structural arrangements, the counterweight assembly and the car assembly near the counterweight portion overlap in vertical space, resulting in a compact structure that effectively reduces the space occupied by the elevator and improves space utilization.

[0016] Compared with the prior art, the advantages of the present invention are: the steel belt traction elevator of the present invention, by setting the parts of the counterweight guide rail, car guide rail, counterweight assembly, and car assembly that cooperate with the car guide rail below the traction machine, can further reduce the occupied space and improve the space utilization rate.

Detailed Implementation

[0024] To enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0025] like Figure 1-5 As shown, the steel belt traction elevator 1 in this embodiment includes a shaft and a traction machine 2, a counterweight assembly, a car assembly, a counterweight guide rail 6, a car guide rail 9, a steel belt 3, a speed detection mechanism, and a control module, all installed within the shaft. The counterweight assembly includes a counterweight frame 5 slidably mounted along the counterweight guide rail 6 and a counterweight 4 installed within the counterweight frame 5. The car assembly includes a car frame, which includes a car floor 7, uprights 8, a first reinforcing plate 14 positioned between the lower parts of the two uprights 8, and a second reinforcing plate 20 positioned between the upper parts of the two uprights 8. The uprights 8 are slidably mounted along the car guide rail 9. The uprights 8 are two oppositely positioned and perpendicular to the car floor 7, fixed to the side of the car floor 7 closest to the counterweight 4. In this embodiment, a main unit base 10 is provided at the top of the counterweight guide rail 6 and the car guide rail 9, and the traction machine 2 is fixed to the main unit base 10. In this embodiment, the traction machine 2 is located directly above the counterweight guide rail 6 and the car guide rail 9. The extension direction of the traction sheave axis in the traction machine 2 is parallel to or lies within the plane containing the counterweight guide rail 6 or the car guide rail 9. Figure 2-4 As shown.

[0026] like Figure 2 and 4 As shown, in this embodiment, the wellbore is formed by splicing together the wellbore wall 17 and the column 18 made of aluminum alloy, and the fixing frame 19 for installing the guide rail is fixedly connected to the wellbore.

[0027] In this embodiment, the traction machine 2, counterweight assembly, counterweight guide rail 6, car guide rail 9, and steel belt 3 of the steel belt traction elevator 1 are all located on one side of the car assembly. The steel belt 3 straddles the traction machine 2, with one end connected to the upper end of the counterweight frame 5 in the counterweight assembly, and the other end connected to the car assembly. The vertical plane containing the counterweight guide rail 6 or the car guide rail 9 is located between the two steel belts 3. Specifically, a connecting plate 15 is provided on the first reinforcing plate 14, and the other end of the steel belt 3 is fixed to the connecting plate 15; that is, the traction ratio of the elevator in this embodiment is 1:1. A notch 16 is provided on the side of the counterweight 4 closest to the car, and the steel belt 3 passes through the notch 16.

[0028] The counterweight guide rail 6 and the car guide rail 9 are located directly below the traction machine 2. Both the counterweight guide rail 6 and the car guide rail 9 include a fixing part and a guiding part. The guiding parts of the counterweight guide rail 6 and the car guide rail 9 are located in the same vertical plane, and the guiding parts of the counterweight guide rail 6 and the car guide rail 9 face opposite directions. The counterweight guide rail 6 and the car guide rail 9 are similar in structure, both being T-shaped guide rail structures. The guiding part is used to guide the movement of the counterweight frame or car frame upright plate, and the fixing part is used to fix it to the fixing frame 19. The fixing frame 19 is fixed to the hoistway, thereby fixing the guide rail. By setting the guiding parts of the counterweight guide rail 6 and the car guide rail 9 to be in the same vertical plane, the structure is more compact and the overall stability of the structure during movement is improved.

[0029] like Figure 4 As shown, the guide portions of the two counterweight guide rails 6 face inwards, i.e., they are close to each other towards the counterweight 4, allowing the counterweight assembly to move between the two counterweight guide rails 6; while the guide portions of the two car guide rails 9 face outwards, resulting in a compact structure. Furthermore, the fixing portions of the same set of counterweight guide rails 6 and car guide rails 9 are close to each other, facilitating installation and fixation via the same fixing bracket 19. The upright plate 8 is located on the outside of the car guide rails 9, and the counterweight assembly moves within the vertical space formed by the two upright plates 8. That is, the counterweight assembly and the two car guide rails 9 are located within the space formed by the two upright plates 8, with the inner side of the upright plate 8 matching and guiding the car guide rails 9, resulting in a compact structure.

[0030] In this embodiment, the speed detection mechanism is a magnetic scale structure, including a magnetic head 13 and a magnetic tape 11. The magnetic head 13 is mounted on the vertical plate 8, and the magnetic tape 11 is positioned inside the hoistway corresponding to the magnetic head 13. Speed ​​measurement is achieved through the cooperation of the magnetic head 13 and the magnetic tape 11, and the measured speed is fed back to the control module. Simultaneously, a safety clamp 12 is positioned on the vertical plate 8 corresponding to the car guide rail 9. The control module controls the safety clamp 12 to actuate based on the speed feedback from the speed detection mechanism. Specifically, the control module can preset a speed threshold. When the control module receives a speed from the car exceeding the preset threshold, it controls the safety clamp 12 to actuate, causing the car to decelerate or stop, ensuring the safe operation of the elevator. The safety clamp 12 is an electronic safety clamp 12. The control module is connected to the safety clamp 12 and the magnetic head 13 via wired or wireless means to achieve signal transmission and control the movement of the components.

[0031] The safety clamp 12 is positioned on the side of the vertical plate 8 closest to the car guide rail 9, ensuring an effective clearance between the electronic safety clamp 12 and the guide rail. The magnetic head 13 is positioned on the side of the vertical plate 8 furthest from the car guide rail 9. Since the car guide rail 9 is located inside the vertical plate 8, the safety clamp 12 is positioned inside the vertical plate 8 to cooperate with the car guide rail 9 to achieve its operation. The magnetic tape 11 is located in the space between the outside of the vertical plate 8 and the hoistway, so the magnetic head 13 is positioned outside the vertical plate 8 to cooperate with the magnetic tape 11 to achieve speed measurement.

[0032] The elevator in this embodiment adopts a steel belt traction drive with a traction ratio of 1:1. It is equipped with an electronic safety clamp 12, eliminating the need for a speed governor and safety clamp 12 linkage structure found in traditional elevators. The electronic safety clamp 12 operates sensitively and reliably, significantly reducing the space occupied in the shaft, resulting in a compact elevator structure that is comfortable, quiet, and improves safety. Furthermore, by placing the counterweight guide rail 6, car guide rail 9, counterweight assembly, and the vertical plate of the car assembly all below the traction machine 2, the vertical plates of the counterweight assembly and car assembly overlap in vertical space, resulting in a compact structure that effectively reduces the elevator's space occupation and improves space utilization. Installation and maintenance are also convenient, reducing production and maintenance costs.

[0033] The above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be used to limit the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
