[0031] The embodiments of this application will be further described below with reference to the accompanying drawings.

[0032] Reference Figure 1 , 2As shown in Figure 3, the elevator car frame includes a lower support mechanism 100, a longitudinal support mechanism 200, and an upper support mechanism 300. The lower support mechanism 100 includes a lower beam 110, a safety gear assembly 120, a lower guide shoe seat 130, and a lower guide shoe 140. The safety gear assembly 120 is disposed on the lower surface of both ends of the lower beam 110, the lower guide shoe seat 130 is disposed on the lower surface of the safety gear assembly 120, and the lower guide shoe 140 is disposed on the lower surface of the lower guide shoe seat 130. The longitudinal support mechanism 200 includes a column 210, which is disposed on the upper surface of both ends of the lower beam 110. The upper support mechanism 300 includes an upper beam 310, an upper guide shoe seat 320, and an upper guide shoe 330. The upper beam 310 is disposed on the upper surface of the column 210, the upper guide shoe seat 320 is disposed on the upper surface of both ends of the upper beam 310, and the upper guide shoe 330 is disposed on the upper surface of the upper guide shoe seat 320.

[0033] In the above embodiments, in the lower support mechanism 100, the number of components is reduced by rationally arranging the lower beam 110, safety clamp assembly 120, lower guide shoe seat 130, and lower guide shoe 140. Furthermore, the safety clamp assembly 120 is located on the lower surface at both ends of the lower beam 110, simplifying the elevator's safety system and reducing complex safety devices. In the longitudinal support mechanism 200, the columns 210 are directly located on the upper surface at both ends of the lower beam 110, avoiding the use of redundant support structures, improving support stability, and reducing the precision requirements during installation. The upper support mechanism 300, by setting the upper beam 310, upper guide shoe seat 320, and upper guide shoe 330, simplifies the design of the upper guiding system, reduces the need for complex components, optimizes the cooperation between components, and improves installation efficiency. Overall, through a rational component layout and the reduction of unnecessary connectors, the required precision during hoisting and installation is reduced, the reliance on large hoisting equipment is decreased, thereby reducing installation costs; the modular design allows for rapid assembly of each component. Compared with the prior art, the embodiments of this application, while ensuring the stability and safety of the elevator, significantly improve installation efficiency and reduce installation difficulty and cost by simplifying the structural design of the elevator car frame and specifically by optimizing the layout and function of each component.

[0034] For example, such as Figure 1 As shown, the lower beam 110 is connected to the first end of the column 210 via a fastener. The second end of the column 210 is connected to the upper beam 310 via a fastener. The lower guide shoe 140 is connected to the lower surface of the lower guide shoe seat 130 via a fastener. The upper guide shoe 330 is connected to the upper surface of the upper guide shoe seat 320 via a fastener.

[0035] Understandably, referring to Figure 2As shown, the lower support mechanism 100 also includes buffer plates 150, which are disposed on both sides of the lower beam 110. The buffer plates 150 are used to dampen vibration and absorb impact for the lower beam 110. By setting the buffer plates 150, vibration is effectively damped and impact is absorbed, protecting the lower beam 110 from excessive impact forces, reducing vibration, extending the service life of the equipment, and improving the stability and comfort of the elevator.

[0036] Understandably, referring to Figure 1 , 2 As shown, the safety clamp assembly 120 includes a safety clamp 121 and a lifting assembly 122. The safety clamp 121 is disposed on the lower surface of both ends of the lower beam 110, and the lifting assembly 122 is disposed between the opposite sides of the buffer plate 150. The drive end of the lifting assembly 122 is connected to the safety clamp 121, and the lifting assembly 122 is used to control the opening and closing of the safety clamp 121. Through the drive control of the lifting assembly 122, the safety clamp 121 can be quickly and accurately opened and closed when necessary, effectively improving the safety of the elevator. The cooperation between the lifting assembly 122 and the safety clamp 121 allows the safety clamp 121 to lock in time when the elevator malfunctions, preventing accidents and ensuring passenger safety.

[0037] Understandably, referring to Figure 1 As shown, the longitudinal support mechanism 200 also includes a diagonal brace bracket 220 and a diagonal brace 230. The diagonal brace bracket 220 is disposed on both sides perpendicular to the column 210 and the lower beam 110, and one end of the diagonal brace 230 is movably connected to the diagonal brace bracket 220. Through the cooperation of the diagonal brace bracket 220 and the diagonal brace 230, the supporting rigidity of the column 210 is improved, effectively preventing tilting or swaying, enhancing structural stability, improving overall load-bearing capacity, and ensuring the safe and reliable operation of the elevator.

[0038] For example, such as Figure 1 As shown, taking the setup of four diagonal brace supports 220 and four diagonal braces 230 as an example, one end of two diagonal braces 230 is connected to the two sides of a column 210 perpendicular to the lower beam 110 via fasteners. The other ends of the two diagonal brace supports 220 are movably connected to one end of each of the two diagonal braces 230 via fasteners. Both diagonal braces 230 are at a certain angle to the line of the column 210. The remaining two diagonal brace supports 220 and two diagonal braces 230 are set up in the same manner as described above.

[0039] Understandably, referring to Figure 1As shown, the longitudinal support mechanism 200 also includes a limiting bracket 240 and a limiting plate 250. The limiting bracket 240 is located on the side of the column 210 perpendicular to the lower beam 110, and one side of the limiting plate 250 is connected to the limiting bracket 240. The cooperation between the limiting bracket 240 and the limiting plate 250 enhances structural stability, effectively limits the displacement of the column 210, prevents swaying or deformation, improves overall support strength, and ensures the safety and reliability of elevator operation.

[0040] For example, such as Figure 1 As shown, taking the installation of two limit brackets 240 and two limit plates 250 as an example, the two limit brackets 240 are respectively connected to the side of the two columns 210 perpendicular to the lower beam 110 via fasteners, and the two limit brackets 240 are respectively connected to the side of the two limit plates 250 facing the two columns 210 via fasteners. By setting up two limit brackets 240 and corresponding two limit plates 250, displacement of the two columns 210 can be effectively prevented, swaying or deformation can be prevented, the overall support strength can be improved, and the safety and reliability of elevator operation can be ensured.

[0041] Understandably, referring to Figure 1 , 3 As shown, the upper support mechanism 300 also includes a rope-blocking assembly 340, which includes a rope plate 341, a rope-blocking rod 342, and a car top pulley 343. The rope plate 341 is disposed on the lower surface of the upper beam 310. Both ends of the rope-blocking rod 342 and both ends of the car top pulley 343 are connected to the opposite sides of the rope plate 341, and the car top pulley 343 is located above the rope-blocking rod 342. Through the cooperation of the rope-blocking rod 342 and the car top pulley 343, the wire rope is effectively prevented from deviating or falling off, wear is reduced, operational stability is improved, and the safety and durability of the elevator are enhanced.

[0042] For example, such as Figure 3 As shown, taking the setup of four rope plates 341, two rope guides 342, and two car top pulleys 343 as an example, the two rope plates 341 are symmetrically arranged. Both rope plates 341 have a perforated section, and the two axles of one car top pulley 343 pass through the perforated sections of the two rope plates 341 and are rotatably connected to them. The two ends of the rope guides 342 are connected to the opposite sides of the two rope plates 341 by fasteners. The remaining two rope plates 341, one rope guide 342, and one car top pulley 343 are arranged similarly. The two rope guides 342 cooperate with the two corresponding car top pulleys 343 to effectively prevent the wire ropes on both sides of the elevator car frame from shifting or falling off, reducing wear, improving operational stability, and enhancing the safety and durability of the elevator.

[0043] Understandably, referring to Figure 3As shown, the upper support mechanism 300 also includes a reinforcing plate 350, which is disposed on opposite sides of the upper beam 310. The reinforcing plate 350 is used to increase the strength and stability of the upper beam 310.

[0044] For example, such as Figure 3 As shown, one side of the upper end of the reinforcing plate 350 is connected to the two sides of the upper beam 310 via fasteners. The lower end of the reinforcing plate 350 is gradually narrowed. This narrowing design reduces stress concentration, avoids structural weaknesses caused by sudden changes in cross-section, and improves overall strength and durability. The gradually narrowing structure reduces unnecessary material usage, reducing weight while maintaining strength, improving the lightweight effect of the structure and enhancing stability. The smooth transition reduces vibration and deformation, improving the stability of the supporting structure, making it particularly suitable for scenarios subjected to dynamic loads. It also reduces manufacturing costs, minimizes material waste, improves processing efficiency, and makes the structure more economical and practical.

[0045] Understandably, referring to Figure 3 As shown, the upper support mechanism 300 also includes an upper dust cover 360 and a lower dust cover 370. The upper dust cover 360 is disposed on the upper surface of the upper beam 310, and the lower dust cover 370 is disposed on the lower surface of the rope plate 341. By setting the upper dust cover 360 and the lower dust cover 370, dust and debris can be effectively prevented from entering key parts such as the upper beam 310 and the rope plate 341, thereby reducing the impact of dust accumulation on equipment operation, extending service life, improving the protective performance of the equipment, and reducing maintenance costs.

[0046] The embodiments of this application do not limit the number of upper dust cover 360 and lower dust cover 370, and those skilled in the art can adjust them according to actual conditions. For example, Figure 3 As shown, taking the installation of an upper dust cover 360 and a lower dust cover 370 as an example, the upper dust cover 360 is bent into a Z-shape, and its lower end is connected to the upper surface of the upper beam 310 by a fastener. The lower dust cover 370 is bent inward to form a bent section, and the opposite sides of the bent section are connected to the rope plate 341 by fasteners. By installing an upper dust cover 360 and a lower dust cover 370, dust and debris are prevented from entering key parts such as the upper beam 310 and the rope plate 341, reducing the impact of dust accumulation on equipment operation, extending service life, improving the protective performance of the equipment, and reducing maintenance costs.

[0047] Understandably, referring to Figure 1 As shown, the longitudinal support mechanism 200 also includes a guardrail 260, with its opposite sides connected to the two perpendicular sides of the column 210 and the lower beam 110. The guardrail 260 reduces the probability of the upper beam 310, column 210, and lower beam 110 being collided with, thus preventing damage or even safety hazards, extending their service life, and improving safety.

[0048] For example, such as Figure 1 As shown, the guardrail 260 can be divided into two parts: a first part and a second part. The first part is open, with one end of the first part near the post 210 connected to the post 210 via a bracket. The second part is closed, with one end of the second part also connected to the post 210 via a bracket. The tops of the first and second parts are connected to form a connecting section, which is located above the reinforcing plate 350. The area below the connecting section is open.

[0049] Understandably, referring to Figure 1 As shown, the upper support mechanism 300 also includes an oil cup 380, which is disposed on the upper surface of the upper guide shoe 330 and is used to provide lubrication for the upper guide shoe 330. By providing the oil cup 380 on the upper surface of the upper guide shoe 330, lubricating oil can be continuously and evenly supplied to the upper guide shoe 330, thereby reducing friction and wear between the guide shoe and the guide rail, improving the operational stability of the upper guide shoe 330, extending its service life, and reducing maintenance costs.

[0050] For example, such as Figure 1 As shown, taking the setting of two oil cups 380 as an example. There are two upper guide shoes 330 in the figure, and each upper surface of the two upper guide shoes 330 is provided with an oil cup 380. Both oil cups 380 can provide lubricating oil to the corresponding upper guide shoes 330, reduce the friction and wear between the two upper guide shoes 330 and the corresponding guide rail, improve the operating stability of the two upper guide shoes 330, extend their service life, and reduce maintenance costs.

[0051] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
