Description

Technical Field

[0001] The present invention relates to the technical field of lifting and hoisting equipment, and particularly relates to a traction rope type elevator. Background Art

[0002] An elevator is a mechanical device or apparatus used for vertically transporting personnel or goods on a vertical passage. Its core function is to achieve vertical transportation by lifting a platform or a semi-enclosed platform. Most vertical elevator technologies rely on a wire rope lifting system, which uses wire ropes as the core components for bearing and transmitting power. Wire ropes can not only withstand high-intensity loads but also adapt to complex working conditions, so they have been widely used in many fields such as construction, manufacturing, and mining. With the further development of material science and engineering technology, the performance of wire ropes will be further improved, and their application scope will also be more extensive. The wire rope lifting technology will play an important role in more fields.

[0003] However, currently, wire rope elevators usually use a single motor as the driving source. Since sufficient power needs to be provided to overcome the load and friction, the power requirement of the motor is relatively high. The large size of the high-power motor leads to an increase in the overall equipment size. In addition, the motor usually adopts an external design, which further reduces the integration degree of the equipment and increases the occupied space. To ensure the stability during the lifting process, the two sides of the cargo frame are usually connected to the main structure through a limiting mechanism to achieve lifting guidance. Although this design enhances the stability of the system, it also makes the overall structure more complex and bulky, reducing the compactness and flexibility of the equipment. Due to the structural complexity and large volume, wire rope elevators have poor flexibility in installation, maintenance, and adapting to different working conditions, and it is difficult to meet the requirements of modern industry for the high efficiency and multi-functionality of equipment.

[0058] The following combines the drawings and embodiments to further describe in detail the specific implementation manners of the present invention. The following examples are used to illustrate the present invention, but are not used to limit the scope of the present invention.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components; The "first end" and the "second end" are opposite ends; "one end" and "the other end" are opposite ends; "one side" and "the other side" are opposite sides; The "first direction" is along the rotation axis direction of the rope - winding mechanism, the "second direction" is along the direction from the first traction mechanism to the second traction mechanism, and the "third direction" is the direction perpendicular to the horizontal plane; The first direction, the second direction, and the third direction are perpendicular to each other. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0060] Traditional wire rope elevators usually use an external, high-power single motor as the driving source, and achieve lifting guidance through the connection between the limit mechanism and the main structure to ensure lifting stability. This results in a large overall structure volume, low integration level, and poor compactness and flexibility of the equipment. To address the above defects, the inventor designed a traction rope elevator that uses multiple small-sized, low-power driving devices as the driving source. Through distributed driving and reasonable integrated design, it can significantly improve the overall integration level of the equipment, optimize the use of internal space, greatly reduce the overall volume of the equipment, and improve the space utilization rate.

[0061] Figure 1 It is a schematic structural diagram of a traction rope elevator according to some embodiments provided by the present invention; Figure 2 It is a front view structural schematic diagram of a traction rope elevator according to some embodiments provided by the present invention; Figure 3 It is a top view structural schematic diagram of a traction rope elevator according to some embodiments provided by the present invention; Figure 4 It is a schematic structural diagram of a load-bearing component 400 according to some embodiments provided by the present invention. Refer to Figures 1 to 4 As shown in the figure, the embodiments of the present invention provide a traction rope elevator, including: a main body frame 100, a first traction mechanism 200, a second traction mechanism 300, and a load-bearing component 400; the main body frame 100 is fixed to an external support; the first traction mechanism 200 is fixed to one end of the main body frame 100; the second traction mechanism 300 is fixed to the other end of the main body frame 100; the load-bearing component 400 is arranged below the main body frame 100, and its two ends are respectively connected to the traction ropes 3 of the first traction mechanism 200 and the second traction mechanism 300; the first traction mechanism 200 and the second traction mechanism 300 respectively include: a driving component 1 and at least one set of rope winding mechanisms 2 and traction ropes 3; one end of the traction rope 3 is wound around the corresponding rope winding mechanism 2, and the other end is connected to the load-bearing component 400; the rope winding mechanism 2 is driven to rotate by the driving component 1 to drive the traction rope 3 to drive the load-bearing component 400 to lift.

[0062] The main body frame 100 is fixed to the external support and together serves as a support component, playing the role of supporting and transmitting loads. Its structural form can be a frame structure, which is composed of several rigid members connected through nodes to form a hollow structure, having characteristics such as high strength, high stiffness, and excellent structural stability. The shape of the frame structure can be designed as a cuboid or other polyhedron forms to meet specific space layout requirements.

[0063] Functional modules such as the driving component 1 and the rope winding mechanism 2 are designed in an integrated manner and are all arranged in the hollow cavity of the frame structure. The horizontal projections of all functional modules are located within the horizontal projection boundary of the main frame 100. Through this non-external integrated layout, the vertical space occupancy of the main frame 100 can be significantly optimized, realizing a compact structure design, and at the same time improving the space utilization efficiency of the overall structure.

[0064] The driving component 1 and the rope winding mechanism 2 can be fixed to the inner end area of the frame structure cavity through mounting parts to achieve the integrated layout of the functional modules. To optimize the structural space utilization rate, the driving component 1 and the rope winding mechanism 2 can adopt a coplanar arrangement method, that is, the two are arranged in the same horizontal plane, wherein the driving component 1 is located outside the rope winding mechanism 2. Through reasonable space arrangement, the vertical space occupancy of the main frame 100 is further reduced, thereby realizing the compact design of the overall structure.

[0065] As the core power source of the entire mechanism, the driving component 1 can adopt various forms of driving devices, including but not limited to electric motors, hydraulic driving devices or pneumatic driving devices, etc. In the embodiment of the present invention, electric motors such as DC motors, stepper motors or servo motors are preferably used. The electric motor can be connected to the speed reducer 4 through a coupling, and the output shaft of the speed reducer 4 is directly coupled to the rotating shaft of the rope winding mechanism 2. Through the transmission of the speed reducer 4, the output speed of the electric motor can be effectively reduced, and at the same time the output torque can be significantly increased, and the transmission direction can be changed according to needs, and it can drive the rope winding mechanism 2 to realize rotational motion, thereby realizing the winding function of the traction rope 3.

[0066] Install a driving component 1 at both ends of the frame structure cavity respectively. The double-driving form has significant advantages compared with the single-driving form. First of all, the double-driving form can effectively reduce the volume of the overall structure through distributed power output, realizing a more compact design; secondly, since the load is shared by the two driving components 1 together, a low-power driving component 1 can be selected, thereby reducing the power requirement for a single driving unit, broadening the selection range of the driving component 1, and improving the flexibility and economy of the design.

[0067] The rope winding mechanism 2 is provided with a rope groove, and the traction rope 3 can be wound along the rope groove to realize the traction function. To facilitate power transmission with the laterally arranged driving component 1, the rope winding mechanism 2 can preferably adopt a cylindrical drum structure, but the specific shape of the rope winding mechanism 2 in the embodiment of the present invention is not specifically limited and can be adaptively adjusted according to the actual application scenario.

[0068] The traction rope 3 can adopt a steel wire rope, which has high strength, high stability and excellent corrosion resistance. The steel wire rope can not only withstand high-intensity loads, ensuring reliability under heavy load conditions, but also adapt to complex and changeable environmental conditions, such as high temperature, humidity or corrosive media, etc., so as to meet the use requirements under various working conditions.

[0069] In some embodiments, referring to Figure 3 , on the side of the driving component 1, two sets of rope winding mechanisms 2 and traction ropes 3 can be arranged at intervals along the first direction; the two traction ropes 3 at one end of the main body frame 100 are connected to the first end of the bearing component 400, and the two traction ropes 3 at the other end of the main body frame 100 are connected to the second end of the bearing component 400, forming a four-point suspension. Adopting a distributed traction form, this design can not only significantly reduce the volume of the overall structure, achieve a more compact space layout, improve space utilization rate, but also effectively disperse the force load through the distribution of multiple traction points, reduce the load intensity of a single traction rope 3, thereby enhancing the reliability and stability of the system. In addition, the arrangement of multiple traction points can also make the movement of the bearing component 400 more stable, reducing vibration and off-loading phenomena.

[0070] In some embodiments, continuing to refer to Figure 3 , the driving component 1 of the first traction mechanism 200 and the driving component 1 of the second traction mechanism 300 are arranged staggeredly. Specifically, two sets of rope winding mechanisms 2 and traction ropes 3 are arranged front and back along the first direction at both ends of the cavity of the frame structure. Among them, the driving component 1 of the first traction mechanism 200 is installed side by side on the outside of the rope winding mechanism 2 at the front side of one end of the cavity, while the driving component 1 of the second traction mechanism 300 is installed side by side on the outside of the rope winding mechanism 2 at the rear side of the other end of the cavity, so that the two driving components 1 are arranged staggeredly in space. Further, referring to Figure 3 , the two rope winding mechanisms 2 at the front sides of both ends of the cavity are connected by a first synchronous chain and are synchronously driven by one of the driving components 1; correspondingly, the two rope winding mechanisms 2 at the rear sides of both ends of the cavity are connected by a second synchronous chain and are synchronously driven by the other driving component 1. This staggered arrangement method significantly enhances the balance of the overall structure by optimizing the power distribution on the front and back sides of the main body frame 100. At the same time, with the help of the distributed power transmission and synchronous drive mechanism, the structural stability of the system is further improved. This design not only effectively reduces the vibration and off-loading phenomena during operation, but also significantly improves the smoothness and reliability of the lifting movement of the bearing component 400.

[0071] The bearing component 400, as a lifting functional unit, is mainly used to realize the vertical lifting movement of the target object, and its structural form can be designed according to specific application scenarios. For example, the bearing component 400 can be a three-dimensional frame structure, applied to elevator car suspension systems and cargo suspension devices, etc.; it can also be a truss structure (as shown in Figure 4 ), and by setting a locking device below the truss structure, the lifted object is fixed and lifted synchronously with the bearing component 400. The bearing component 400 can be made of high-strength rigid materials to ensure stable and reliable load transmission during the lifting process.

[0072] In the technical solution of the embodiment of the present invention, functional modules such as the driving component 1 and the rope winding mechanism 2 adopt an integrated layout design, and are all arranged in the inner cavity space of the main frame 100. A driving component 1 and multiple groups of rope winding mechanisms 2 are respectively arranged at both ends of the inner cavity of the main frame 100, and the lifting movement of the load-bearing component 400 is driven in a distributed traction form. On the one hand, through this non-external integrated layout, the vertical space occupation of the main frame 100 can be significantly optimized, the structural compact design can be realized, and at the same time, the space utilization efficiency of the overall structure can be improved; on the other hand, compared with the single-drive form, the dual-drive form adopts distributed power output, which not only effectively reduces the volume of the overall structure, further optimizes the space layout, but also reduces the power requirement for a single drive unit through load sharing, broadens the selection range of the driving component 1, improves the design flexibility, and reduces the system cost.

[0073] Figure 5 It is a schematic connection structure diagram of the driving component 1, the rope winding mechanism 2 and the pulley block 500 provided by some embodiments of the present invention; Figure 6 It is a schematic connection structure diagram of the towing rope 3 and the pulley block 500 provided by some embodiments of the present invention. Based on the same inventive concept, in some embodiments, refer to Figure 5 and Figure 6 , the towing rope type elevator further includes: a pulley block 500 for changing the direction of the towing rope 3; the pulley block 500 includes: a first fixed pulley 501, a third fixed pulley 503 and a second fixed pulley 502 arranged in sequence along the second direction; the towing rope 3 of the first towing mechanism 200 is respectively wound around the lower part of the third fixed pulley 503 and the upper part of the second fixed pulley 502 and connected to the load-bearing component 400; the towing rope 3 of the second towing mechanism 300 is wound around the upper part of the first fixed pulley 501 and connected to the load-bearing component 400.

[0074] The fixed pulley can be used as a support point to guide the movement direction of the towing rope 3. Its function is not limited to changing the direction of the applied force, thereby improving the convenience of operation, but also being able to transmit the applied force to the other end while keeping the magnitude of the force unchanged.

[0075] Figure 7 It is a front view structural schematic diagram of the towing rope type elevator provided by some other embodiments of the present invention; Figure 8 It is a left view structural schematic diagram of the towing rope type elevator provided by some embodiments of the present invention; Figure 9 It is a left view structural schematic diagram of the towing rope type elevator provided by some other embodiments of the present invention. Refer to Figures 7 to 9, in some embodiments, the tangent point of the towing rope 3 of the first towing mechanism 200 and the second fixed pulley 502 is A1; the tangent point of the towing rope 3 of the second towing mechanism 300 and the first fixed pulley 501 is A2; the connection points of the towing rope 3 of the first towing mechanism 200 and the towing rope 3 of the second towing mechanism 300 with the bearing member 400 are B1 and B2 respectively; the distance between A1 and A2 is L1; the distance between B1 and B2 is L2; the distance between adjacent two A1s is L3; the distance between adjacent two B1s is L4; wherein, L1 > L2, L3 > L4. This design makes the towing rope 3 connecting the main body frame 100 and the bearing member 400 form a quadrangular prism space structure with an inverted trapezoidal side. Compared with the cuboid structure formed by the towing rope 3 in the traditional wire rope vertical lifting mechanism, the inverted trapezoidal quadrangular prism structure adopted in the embodiment of the present invention enables the system to have certain anti-vibration and anti-shake performance through its geometric characteristics, thereby significantly improving the stability and operation reliability of the overall structure.

[0076] In some embodiments, refer to Figure 6 , in the third direction, the highest point M1 of the first fixed pulley 501 is higher than the highest point M2 of the second fixed pulley 502, and the highest point M2 of the second fixed pulley 502 is higher than the highest point M3 of the third fixed pulley 503; the lowest point N1 of the first fixed pulley 501 is higher than the lowest point N3 of the third fixed pulley 503, and the lowest point N3 of the third fixed pulley 503 is higher than the lowest point N2 of the second fixed pulley 502. In order to optimize the compactness of the spatial layout, the first fixed pulley 501, the second fixed pulley 502 and the third fixed pulley 503 are arranged in the same direction and a height difference is set in the vertical direction. This arrangement method can achieve mutual avoidance during the winding process of the towing rope 3, effectively avoiding the contact and friction between the towing ropes 3, thereby reducing wear and improving the operation stability and service life of the system.

[0077] In some embodiments, refer to Figure 9 , there is a certain inclination angle between the pulley block 500 and the vertical plane. Specifically, the first fixed pulley 501, the second fixed pulley 502 and the third fixed pulley 503 all form equal inclination angles with the vertical plane and are inclined along the first direction. Through research, the inventor found that the inclined arrangement of the pulley block 500 can significantly improve the movement stability and safety of the towing rope 3 during the extension and retraction process. After multiple experimental verifications, when the inclination angle α is in the range of 5° to 12°, the movement smoothness of the towing rope 3 reaches a better state, especially when the inclination angle α is 8°, it reaches the best, effectively reducing the vibration and offset phenomena, thereby improving the overall reliability of the system.

[0080] Furthermore, in some embodiments, the connection component 600 further includes: a second rotating shaft 604 and a second connecting piece 605; the second connecting piece 605 is hinged to the first connecting piece 603 through the second rotating shaft 604; an annular groove 605a is provided on the second connecting piece 605, and the traction rope 3 is wound and fixed in the annular groove 605a; the first rotating shaft 602 and the second rotating shaft 604 are cross - arranged.
