Description

Technical Field

[0001] This utility model belongs to the field of elevator technology, specifically a car connection mechanism suitable for multi-directional elevator operation. Background Technology

[0002] Multi-directional elevators have become a research hotspot due to the demands of complex building structures. Traditional elevator systems rely on a single track for vertical movement, which is insufficient to meet the requirements for flexible operation. Achieving stable connection and switching operation of the car in multiple directions is a key technical challenge. Existing technologies involve the design of multiple cars operating in parallel, track switching, and guiding devices, but their application still has limitations.

[0003] A search revealed a guide device for multi-car parallel elevators, publication number CN115535781B, published on September 24, 2024. This patent uses multiple wheels on the upper guide mechanism to contact the guide rail, achieving the limiting and guiding functions of the car's movement along the guide rail, improving elevator stability and adapting to both vertical and curved track requirements. However, this solution mainly addresses the parallel operation of multiple cars on the same track, neglecting the switching connection between tracks in different directions. Especially when the car needs to smoothly transition to tracks with different directions, it lacks effective support, limiting its application in multi-directional elevator systems.

[0004] A search revealed a patent for an operating system for a multi-car elevator, publication number CN113830645B, published on August 4, 2023. This patent proposes a system combining a main track mechanism and a switching mechanism, enabling the car to switch between different main tracks, improving flexibility and transportation efficiency. However, this switching mechanism is suitable for switching parallel or coplanar tracks, and provides insufficient support for switching between non-coplanar or multi-angle tracks. Furthermore, positioning deviations may occur during the switching process, affecting the car's operational stability and safety, making it difficult to meet the demands of multi-directional elevators for rapid and precise switching.

[0005] In summary, existing technologies still have significant shortcomings when dealing with multi-directional operation scenarios: on the one hand, the guiding device has limited support for stable connections between tracks in different directions; on the other hand, the switching mechanism lacks adaptability when facing switching between non-coplanar or multi-angle tracks, and its positioning accuracy needs improvement. Therefore, there is an urgent need for a new car connection mechanism suitable for multi-directional elevator operation to solve the above problems and achieve efficient, safe, and stable multi-directional operation of elevators in complex track systems. Utility Model Content

[0006] This utility model provides a car connection mechanism suitable for multi-directional elevator operation. By setting an adjustable transition module between the car and the track, a smooth connection is achieved when switching between tracks in different directions. At the same time, a positioning device is used to improve the accuracy of the switching process, thereby solving the problems of insufficient adaptability and positioning deviation in the prior art for switching between non-coplanar or multi-angle tracks.

[0007] A car connection mechanism suitable for multi-directional elevator operation includes a transition module, a positioning device, and a support assembly. The transition module is installed at the bottom of the car, the positioning device is located on both sides of the transition module, and the support assembly is fixed to the lower end of the transition module. The transition module includes a rotating seat, a guide slider, and a limiting member. The rotating seat is connected to the bottom of the car by bolts, the guide slider is embedded in the rotating seat and fixed by a pin, and the limiting member is located on the outside of the rotating seat and cooperates with the guide slider. The positioning device includes a guide rod, an elastic element, and a positioning pin. One end of the guide rod is welded to the rotating seat, and the other end is connected to the positioning pin. The elastic element is sleeved on the outside of the guide rod and contacts the positioning pin. The support assembly includes a support plate and reinforcing ribs. The support plate is fixedly connected to the transition module by screws, and the reinforcing ribs are welded to both sides of the support plate.

[0008] As a further improvement, the rotating seat is a disc-shaped structure with multiple arc-shaped grooves. The arc-shaped grooves are evenly distributed along the circumference of the rotating seat. The guide slider cooperates with the rotating seat through the arc-shaped grooves to achieve angle adjustment when switching between multiple directions of tracks.

[0009] As a further improvement, the width of the arc-shaped groove is 10mm-20mm, the thickness of the guide slider is 8mm-18mm, and the gap between the guide slider and the arc-shaped groove is 1mm-3mm, so as to ensure the smooth sliding of the guide slider in the arc-shaped groove.

[0010] As a further improvement, the limiting member is an L-shaped structure, with one end fixed to the outside of the rotating seat by bolts, and the other end in contact with the side of the guide slider, which is used to limit the movement range of the guide slider and prevent it from leaving the arc groove.

[0011] As a further improvement, the guide rod is a stepped shaft structure, with its larger diameter end welded to the rotating seat and its smaller diameter end connected to the positioning pin via a thread. The elastic element is a compression spring, with its two ends in contact with the guide rod and the positioning pin respectively, to provide a buffering effect during track switching.

[0012] As a further improvement, the positioning pin is a cylindrical structure with multiple annular grooves on its outer surface. The depth of the annular grooves is 0.5mm-1mm. The positioning pin cooperates with the positioning holes on the track through the annular grooves to improve the positioning accuracy when switching tracks.

[0013] As a further improvement, the support plate has a rectangular structure with multiple through holes, the diameter of which is 8mm-12mm, to reduce the weight of the support plate and facilitate installation and disassembly.

[0014] As a further improvement, the reinforcing rib is a triangular structure with a thickness of 5mm-8mm. The two sides of the reinforcing rib are welded to the support plate and the transition module, respectively, to enhance the strength of the support plate and prevent it from deforming during track switching.

[0015] As a further improvement, a shock-absorbing pad is provided between the rotating seat of the transition module and the bottom of the car. The shock-absorbing pad is made of rubber and has a thickness of 3mm-5mm. It is used to reduce the vibration generated during track switching and improve the smoothness of car operation.

[0016] As a further improvement, a lubricating coating is provided between the guide rod and the rotating seat of the positioning device. The lubricating coating is made of polytetrafluoroethylene and has a thickness of 0.1mm-0.3mm. This coating is used to reduce the friction between the guide rod and the rotating seat and extend their service life.

[0017] This invention achieves smooth switching of the car between tracks in different directions by incorporating a rotating seat and guide slider in the transition module, combined with guide rods and positioning pins in the positioning device. Simultaneously, the support plates and reinforcing ribs in the support assembly improve the overall structural stability. Furthermore, the application of shock-absorbing pads and lubricating coatings further enhances the smoothness of car operation and the durability of components.

[0018] The specific implementation of the above technical solution is as follows: When the car needs to switch from one track to another track with a different direction, the rotating seat adjusts its angle through the cooperation of the arc-shaped groove and the guide slider. The positioning pin in the positioning device cooperates with the positioning hole on the track through the annular groove to ensure accurate positioning during the switching process. The support plate and reinforcing ribs in the support assembly provide sufficient strength support for the entire mechanism, while the shock-absorbing pads and lubricating coating reduce vibration and friction, respectively, thereby ensuring the efficient, safe, and stable operation of the car in the complex track system.

[0025] This utility model provides a car connection mechanism suitable for multi-directional elevator operation, and its specific implementation is as follows. Figure 1 As shown, the mechanism includes a transition module 1, a positioning device 2, and a support assembly 3. The specific structure and connection relationships of these components will be described in detail below. The transition module 1 is installed at the bottom of the car and has a rotating seat 4, a guide slider 5, and a limiting component 6 on it. The angle adjustment function is achieved through the cooperation of these components. The positioning device 2 is located on both sides of the rotating seat 4 and includes a guide rod 7, an elastic element 8, and a positioning pin 9, used to improve the accuracy during track switching. The support assembly 3 is fixed to the lower end of the transition module 1 and consists of a support plate 10 and reinforcing ribs 11, used to enhance the stability of the overall structure.

[0026] according to Figure 2 As shown in the enlarged view, the rotating base 4 is a disc-shaped structure with multiple arc-shaped grooves evenly distributed along its circumference. The guide slider 5 is embedded within the rotating base 4 and fixedly connected to it via a pin. The guide slider 5 has a thickness of 8mm-18mm, the arc-shaped groove width is 10mm-20mm, and the gap between them is 1mm-3mm to ensure smooth sliding within the groove. The limiting member 6 is an L-shaped structure; one end is bolted to the outside of the rotating base 4, and the other end contacts the side of the guide slider 5, limiting its range of motion and preventing it from detaching from the arc-shaped groove. This design allows the guide slider 5 to maintain a stable force state while sliding within the arc-shaped groove, thus enabling angle adjustment during track switching in different directions.

[0027] Combination Figure 3The schematic diagram of the positioning device shows that the guide rod 7 is a stepped shaft structure, with its larger diameter end welded to the rotating seat 4, and its smaller diameter end connected to the positioning pin 9 via threads. The elastic element 8 is a compression spring, which is sleeved on the outside of the guide rod 7 and contacts both the guide rod 7 and the positioning pin 9. When the car needs to switch tracks, the positioning pin 9 engages with the positioning hole on the track through an annular groove on its outer surface. The depth of the annular groove is 0.5mm-1mm. This design improves the fitting accuracy between the positioning pin 9 and the positioning hole, thereby ensuring accurate positioning during track switching. The elastic element 8 acts as a buffer during track switching, reducing vibration caused by impact.

[0028] Figure 4 The specific structure of support component 3 is shown. Support plate 10 is a rectangular structure with multiple through holes, each 8mm-12mm in diameter. These through holes not only reduce the weight of support plate 10 but also facilitate installation and disassembly. Reinforcing ribs 11 are triangular structures with a thickness of 5mm-8mm. The two sides of reinforcing ribs 11 are welded to both support plate 10 and transition module 1, thereby enhancing the strength of support plate 10 and preventing deformation during track switching. Support plate 10 is fixedly connected to transition module 1 with screws, ensuring sufficient rigidity and stability of the entire mechanism during operation.

[0029] In practical applications, a shock-absorbing pad is installed between the rotating seat 4 of the transition module 1 and the bottom of the car. The shock-absorbing pad is made of rubber and has a thickness of 3mm-5mm. The installation of the shock-absorbing pad can effectively reduce the vibration generated during track switching and improve the smoothness of car operation. Meanwhile, in the positioning device 2, a lubricating coating is applied between the guide rod 7 and the rotating seat 4. The lubricating coating is made of polytetrafluoroethylene and has a thickness of 0.1mm-0.3mm. The use of the lubricating coating reduces the friction between the guide rod 7 and the rotating seat 4, extending the service life of the components.

[0030] When the car needs to switch from one track to another with a different direction, the angle is first adjusted by the interaction between the arc-shaped groove on the rotating seat 4 and the guide slider 5. The sliding of the guide slider 5 within the arc-shaped groove drives the rotating seat 4 to rotate, thus completing the angle change of the car. During this process, the limiting component 6 restricts the movement range of the guide slider 5, ensuring that it always remains within the arc-shaped groove. At the same time, the positioning pin 9 in the positioning device 2 engages with the positioning hole on the track through an annular groove, ensuring accurate positioning of the car when switching tracks. The elastic element 8 acts as a buffer during track switching, reducing vibration caused by impact and making the switching process smoother.

[0031] The support plate 10 and reinforcing rib 11 in the support assembly 3 provide sufficient strength support throughout the switching process. The support plate 10 is fixedly connected to the transition module 1 by screws, while the reinforcing rib 11 is connected to the support plate 10 and the transition module 1 by welding, forming a stable support structure. This structural design can effectively prevent the support plate 10 from deforming during track switching, thereby ensuring the stability and reliability of the entire mechanism.

[0032] In summary, this invention achieves smooth switching of the car between tracks in different directions by setting a rotating seat 4 and a guide slider 5 in the transition module 1, combined with the guide rod 7 and positioning pin 9 in the positioning device 2. Meanwhile, the support plate 10 and reinforcing ribs 11 in the support assembly 3 improve the overall structural stability. The application of shock-absorbing pads and lubricating coatings further enhances the smoothness of car operation and the durability of components.

[0033] To enable those skilled in the art to fully understand and implement this utility model, the specific implementation principles of this utility model are further explained below in conjunction with specific application scenarios.

[0034] In multi-directional elevator systems, the car needs to frequently switch between tracks in different directions. For example, in a complex building structure containing vertical, horizontal, and diagonal tracks, the car must be able to smoothly and precisely transition from vertical to horizontal tracks. This invention solves this problem through a unique structural design.

[0035] First, as the car approaches the track switching point, the guide slider 5 on the rotating seat 4 begins to slide along the arc-shaped groove. The guide slider 5 has a thickness of 8mm-18mm, and the gap between it and the arc-shaped groove (10mm-20mm wide) is designed to be 1mm-3mm, ensuring smooth sliding. Simultaneously, the limiting member 6, with its L-shaped structure, restricts the movement range of the guide slider 5, preventing it from disengaging from the arc-shaped groove. This design allows the rotating seat 4 to change angles under the influence of the guide slider 5, thus adapting to the needs of different track directions. During this process, the damping pads effectively reduce vibrations caused by track switching, further improving the stability of the car's operation.

[0036] Meanwhile, the positioning pin 9 in the positioning device 2 engages with the positioning hole on the track via an annular groove, achieving precise positioning during the switching process. The depth of the annular groove is 0.5mm-1mm, a design that significantly improves the fit accuracy between the positioning pin 9 and the positioning hole. The elastic element 8, acting as a compression spring, buffers the movement during track switching, reducing vibrations caused by impacts and ensuring a smoother switching process. Furthermore, the polytetrafluoroethylene lubricating coating between the guide rod 7 and the rotating seat 4 reduces friction and extends the service life of the components.

[0037] Support assembly 3 provides necessary strength support throughout the switching process. Support plate 10 is fixedly connected to transition module 1 with screws; multiple through holes on it not only reduce weight but also facilitate installation and disassembly. Reinforcing ribs 11 are triangular structures with a thickness of 5mm-8mm, and are welded to both support plate 10 and transition module 1, enhancing the rigidity and stability of the overall structure. This design effectively prevents deformation of support plate 10 during track switching, thus ensuring the reliability of the entire mechanism.

[0038] In actual operation, when the car switches from a vertical track to a horizontal track, the rotating seat 4 adjusts its angle through the cooperation of the arc-shaped groove and the guide slider 5. The sliding of the guide slider 5 within the arc-shaped groove drives the rotating seat 4 to rotate, aligning the car's angle with the target track direction. Subsequently, the positioning pin 9 engages tightly with the positioning hole on the target track through the annular groove, ensuring the car accurately enters the new track. The elastic element 8 absorbs the switching impact during this process, reducing the impact of vibration on car operation. The support plate 10 and the reinforcing rib 11 jointly bear the load during the switching process, preventing structural deformation and ensuring the safety of the switching operation.

[0039] Through the above steps, this invention achieves smooth switching of the elevator car between tracks in different directions. The cooperation between the rotating seat 4 and the guide slider 5 completes the angle adjustment, the positioning pin 9 in the positioning device 2 ensures precise positioning, and the support component 3 provides sufficient structural strength. The application of shock-absorbing pads and lubricating coatings further improves the smoothness of car operation and the durability of components, thereby meeting the needs of multi-directional elevator systems for efficient, safe, and stable operation in complex track environments.

[0040] In summary, this utility model, through the synergistic effect of its components, successfully solves the problems of insufficient adaptability to switching between non-coplanar or multi-angle tracks and positioning deviations in the prior art, providing reliable technical support for the widespread application of multi-directional elevator systems.
