[0017] Further defining the elevator structure described above, the car frame assembly includes frame columns, a support platform, tie rods, and a top frame, wherein the support platform and the top frame are arranged in parallel in the longitudinal direction;

[0018] The frame column is fixedly installed between the support platform and the top frame and is located on the side of the car assembly closer to the guide rail assembly, while the tie rod is fixedly installed between the support platform and the top frame and is located on the side of the car assembly away from the guide rail assembly.

All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0039] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0040] The elevator structure provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0041] This application provides an elevator structure, such as... Figures 1 to 4 As shown, it includes a guide rail assembly, a traction drive unit, a car frame assembly 100 that slides with the guide rail assembly, and a car assembly 200 that is fixedly connected to the car frame assembly 100.

[0042] The traction drive unit includes a traction rope 300 and a traction mechanism 700 for controlling the winding and unwinding of the traction rope 300. A deflector pulley 160 is rotatably provided on the top of the car frame assembly 100. The end of the traction rope 300 away from the ground passes around the deflector pulley 160 and is fixedly connected to the top wall of the shaft.

[0043] The car assembly 200 includes a car frame and a car door operator and door frame assembly 210 fixedly mounted on the car frame.

[0044] In the horizontal coordinate system, the guide rail assembly is located on one side of the car frame, and the car door operator & door lintel assembly 210 is specifically configured to be on a different side from the car frame and the guide rail assembly.

[0045] In this embodiment, the elevator structure described above is adopted. The guide rail assembly is located on one side of the car frame, which is compact, easy to load and unload, and occupies little space. Compared with the structure of the gantry frame, the actual usable area of ​​the car assembly 200 is larger, and the car door operator and lintel assembly 210 can be set on the other three sides of the car frame relative to the guide rail assembly, making the door opening direction more flexible and improving the applicability of the device in different application scenarios.

[0046] In a preferred embodiment, the number of car door operator and door frame assemblies 210 installed on the car frame is greater than one and less than four.

[0047] When multiple car door operators and door lintel assemblies 210 are provided, the multiple car door operators and door lintel assemblies 210 are located on different sides of the car frame in the horizontal coordinate system.

[0048] Understandably, since multiple car door operators and door frame assemblies 210 can be installed on the car frame, the car frame has a higher degree of freedom in opening and closing directions, thereby improving the elevator's adaptability to different application scenarios.

[0049] In a preferred embodiment, such as Figure 1 As shown, a counterweight device is fixedly connected to the end of the traction rope 300 away from the top wall of the shaft, and the guide rail assembly includes a main rail 500 and a counterweight guide rail 600 fixedly installed on the shaft wall.

[0050] The counterweight guide rail 600 is fixedly connected to the main rail 500 and is located on the side of the main rail 500 away from the car assembly 200. The car frame assembly 100 is slidably mounted on the main rail 500, and the counterweight device is slidably mounted on the counterweight guide rail 600.

[0051] It is understandable that setting the main rail 500 and the counterweight guide rail 600 on the same side of the car frame helps to reduce the overall area occupied by the elevator. The traction rope 300 passes around the anti-rope pulley 160 and its two ends are fixedly connected to the counterweight device and the top wall of the shaft, respectively. The lifting and lowering control of the car component 200 in the shaft can be realized by driving the traction rope 300 to extend and retract through the traction mechanism 700.

[0052] In a preferred embodiment, such as Figure 1 As shown, an installation frame 400 is fixedly installed on the top wall of the shaft, a traction mechanism 700 is fixedly installed on the installation frame 400, and the end of the traction rope 300 away from the ground is fixedly connected to the installation frame 400.

[0053] In a preferred embodiment, such as Figure 1 , Figure 3 As shown, two sets of anti-cord pulleys 160 are provided on the top of the car frame assembly 100, and each set of anti-cord pulleys 160 includes at least one anti-cord pulley 160 that is rotatably connected to the car frame assembly 100.

[0054] Two sets of anti-rope pulleys 160 are symmetrically arranged on the top of the car frame assembly 100 and their central axes are parallel to each other. The end of the traction rope 300 away from the ground passes around the two sets of anti-rope pulleys 160 and is fixedly connected to the mounting frame 400.

[0055] It is understood that the traction mechanism 700 includes a traction machine and a traction sheave connected to the power output end of the traction machine. The traction rope 300 is wound around the traction sheave. When the traction machine drives the traction sheave to rotate, it can drive the traction rope 300 to be wound and unwound, thereby realizing the lifting and lowering control of the car assembly 200.

[0056] In this embodiment, the elevator structure described above is used. The traction rope 300 passes around the traction sheave and the anti-rope sheave 160 and is fixed to the top wall of the shaft. This not only realizes the guidance and control of the traction rope 300, but also eliminates the off-center load compared with the backpack-type structure, resulting in stronger structural stability, thereby achieving a higher lifting height, a larger load capacity, and a faster lifting speed.

[0057] In a preferred embodiment, such as Figures 1 to 3 As shown, the car frame assembly 100 includes a frame column 110, a support platform 120, a tie rod 130, and a top frame 140.

[0058] The support platform 120 and the top frame 140 are arranged in parallel in the longitudinal direction. The frame column 110 is fixedly installed between the support platform 120 and the top frame 140 and located on the side of the car assembly 200 close to the guide rail assembly. The tie rod 130 is fixedly installed between the support platform 120 and the top frame 140 and located on the side of the car assembly 200 away from the guide rail assembly.

[0059] In a preferred embodiment, such as Figures 1 to 3 As shown, the longitudinal projections of the support platform 120 and the top frame 140 are set as squares.

[0060] There are two of each of the frame column component 110 and tie rod 130.

[0061] Among them, the two frame columns 110 are located at the two corners of the support platform 120 and the top frame 140 near the guide rail assembly, respectively, and the two tie rods 130 are located at the two corners of the support platform 120 and the top frame 140 away from the guide rail assembly, respectively.

[0062] Understandably, the four-sided fixed frame structure is formed by the two frame columns 110 and the tie rods 130, which makes the structure more stable.

[0063] In a preferred embodiment, such as Figures 1 to 3 As shown, the top frame 140 has a hollow cavity, and the anti-rope wheel 160 is rotatably mounted on the inner wall of the hollow cavity.

[0064] A cover plate 150 is fixedly installed on the end face of the top frame 140 away from the ground.

[0065] Understandably, the cover plate 150 can shield the hollow cavity of the top frame 140, thereby improving the dustproof and sealing performance of the anti-cord pulley 160, and thus improving the reliability and stability of the elevator drive.

[0066] In a preferred embodiment, such as Figure 1 , Figure 4 As shown, the car frame includes a crossbar 220, a car column 230, and a wall panel 240 fixedly connected to the crossbar 220 and the car column 230.

[0067] It is understandable that the elevator car is formed by the crossbar 220, the car column 230, and the wall panel 240, while the car door operator and door frame assembly 210 are fixedly installed on the car frame for the opening and closing control of the elevator car.

[0068] In a preferred embodiment, the crossbar 220 and the car pillar 230 are specifically aluminum alloy profiles with mounting grooves, and the wall panel 240 is installed in the mounting grooves of the crossbar 220 and the car pillar 230.

[0069] It is understandable that setting the crossbar 220, the car column 230, and the wall panel 240 as a modular structure can improve the loading and unloading efficiency of the car frame.

[0070] In a preferred embodiment, the top and bottom of the car frame are respectively provided with mounting interfaces for installing the car door operator and door frame assembly 210 in four directions with respect to the horizontal coordinate system.

[0071] Understandably, the modular design of the car frame enables the modular installation of the car components 200 and the free arrangement of the car door operator and lintel components 210, further improving the overall applicability and practicality of the device.
