Description

Technical Field

[0001] The present invention relates to the technical field of freight elevators, and in particular to a shock-absorbing traction freight elevator that facilitates the movement of goods. Background Art

[0002] In modern industry and logistics, freight elevators, as essential vertical transportation equipment, are widely used in factories, warehouses, logistics centers, and other locations, fulfilling the critical task of efficiently transporting goods. Traditional traction freight elevators typically utilize a simple wire rope hoisting system with a basic car frame, centered around enabling vertical lift and transportation of goods. However, these traditional freight elevators exhibit numerous operational drawbacks, particularly regarding shock absorption and stability during cargo movement.

[0003] Due to the lack of effective shock-absorbing measures, freight elevators are prone to vibrations during startup, braking, and operation. These vibrations not only cause additional wear and tear on the elevator's mechanical components, shortening the equipment's service life, but also pose a risk of damage to the goods being transported. For example, when transporting fragile items such as precision instruments, ceramics, and enamelware, the vibrations of traditional freight elevators can cause instrument accuracy to decrease and items to break, resulting in significant economic losses. Although some existing freight elevators have been improved by adding simple devices such as shock-absorbing springs and rubber cushions, these measures can only alleviate vibrations to a certain extent and cannot fundamentally solve core problems such as wire rope tension fluctuations and running track deviations. Summary of the Invention

[0042] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0043] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0044] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0045] For example 1, please refer to Figure 1 and Figure 2 This product provides a shock-absorbing traction freight elevator that facilitates cargo movement. Its core structure consists of a freight elevator car 1, a car roof frame 2, a hoisting base 3, and multiple functional components. The freight elevator car 1 serves as the main space for loading cargo, and the car roof frame 2 is fixed to its top with high-strength bolts, forming a stable superstructure. Multiple hoisting bases 3 are symmetrically distributed on the sides of the car roof frame 2, laying the foundation for the installation of subsequent components.

[0046] Along the vertical surface of each lifting base 3, the material input component 4, the steering tensioning component 5 and the turnover clamping roller component 6 are arranged in order from top to bottom. In the material input component 4, the input support sensing component 41 adopts a design that combines a high-precision pressure sensor with a high-strength alloy support plate, which can accurately sense the weight and position of the material. The matching guide roller 42 is made of a wear-resistant rubber-coated metal wheel core, which can effectively reduce the friction loss of the wire rope. The pressure sensing component 51 of the steering tensioning component 5 has a built-in pressure feedback device that can monitor and adjust the pressure in real time. The tensioning roller assembly 52 assembled on its operating surface consists of multiple independently rotatable rollers, which can flexibly adapt to the tensioning requirements under different working conditions. The guide roller 42 at the docking point with the input support sensing component 41 further optimizes the steering path of the wire rope.

[0047] Positioning support assemblies 7 are positioned on the sidewalls of the car roof frame 2, corresponding to the positions of each hoisting base 3. The support roller assembly 71 consists of multiple parallel, high-strength rollers with a non-slip surface treatment, providing stable support for the wire rope. The anti-sway limiter frame 72 utilizes a symmetrical, rigid structure to effectively limit wire rope sway. Furthermore, a calibration compensation slot 9, defined within the car roof frame 2, houses a composite buffer and compensation assembly. The steering support rollers 8 on either side of the slot utilize self-lubricating bearings to ensure smooth wire rope steering.

[0048] The operation of this shock-absorbing traction freight elevator revolves around the path of the wire rope. The wire rope enters the starting end of the input support sensor assembly 41 and, guided by the guide roller 42, is directed to the tensioning roller assembly 52. ​​At this point, the pressure sensor assembly 51 automatically adjusts the pressure of the tensioning roller assembly 52 based on preset parameters and actual operating conditions, achieving primary tensioning of the wire rope. After primary tensioning, the wire rope is output to the revolving clamping roller assembly 6, where friction between the clamping rollers achieves secondary tensioning, further improving the stability of the wire rope tension.

[0049] After secondary tensioning, the wire rope passes through the steering roller 8 on one side and enters the calibration and compensation groove 9. Within the groove, the buffer and compensation assembly uses the elastic deformation of the spring and the damping action of the damper to calibrate and compensate for wire rope tension fluctuations in real time, ensuring constant tension. The wire rope then passes through the steering roller 8 on the other side and finally connects to the supporting roller group 71, where it is secured at the terminal end by the anti-sway limit frame 72. Throughout this process, various components work together to ensure the stability of the wire rope during operation through multi-stage tensioning and guiding, thereby ensuring the smooth rise and fall of the freight elevator car 1.

[0050] The wire rope is controlled and adjusted in sections using various functional components. The material input assembly 4 and the steering tensioning assembly 5 establish and initially adjust the initial tension of the wire rope; the revolving clamping roller assembly 6 strengthens the tension; and the buffering and compensating components within the calibration and compensation groove 9 dynamically compensate for tension fluctuations caused by factors such as cargo weight changes and mechanical vibration during operation. Furthermore, the rational steering design of components such as the guide roller 42 and the steering support roller 8 optimizes the direction of force applied to the wire rope, reduces wear, and improves system reliability.

[0051] This embodiment of a shock-absorbing traction freight elevator, designed to facilitate cargo movement, exhibits significant benefits. Regarding shock absorption, the buffer compensating components within the calibration compensating slots 9 effectively absorb vibration energy during elevator operation, reducing the impact of vibration on cargo. This makes it particularly suitable for transporting vibration-sensitive goods such as precision instruments and fragile items. Regarding cargo movement convenience, the multi-stage tensioning and guiding design ensures smooth operation, preventing car sway caused by loose or uneven wire rope tension. This keeps cargo stable during the lift and facilitates loading and unloading operations.

[0052] Furthermore, the sensing and automatic adjustment features of various components, such as the input support sensor 41 and the pressure sensor 51, enable real-time monitoring of operating conditions and dynamic adjustments, reducing manual intervention and enhancing the intelligent operation and safety of the freight elevator. The use of wear-resistant and self-lubricating materials extends the service life of various components, reduces maintenance costs, and improves the overall economic efficiency and practicality of the freight elevator.

[0053] Example 2: Based on the contents of the above embodiment, the specific implementation structure of the material input component 4 is designed as follows:

[0054] The input base plate 43 is firmly mounted on the frame of the lifting base 3, providing a solid installation foundation for the entire assembly. The input support sensing assembly 41 and the guide roller 42 are arranged in an orderly manner on the input base plate 43. The structure of the input support sensing assembly 41 is particularly delicate, consisting of a rope guide frame 411, a feed roller 412, a support frame 415 and a support panel 413. The feed roller 412 installed on the top of the rope guide frame 411 is made of high-strength alloy steel, and the surface is precisely polished, which can effectively reduce the friction resistance when the wire rope enters. The support panel 413 forms a support guide groove 414 through regularly arranged ribs. The shape and size of the guide groove are precisely designed to match the specifications of the wire rope, ensuring that the wire rope can pass through it stably. The support panel 413 and the support frame 415 adopt a dovetail groove sliding fit structure, which allows the support panel 413 to slide flexibly on the surface of the support frame 415.

[0055] Meanwhile, a fluctuation detection sensor 416 mounted on the surface of the input base plate 43 not only provides support for the support frame 415 but also monitors the fluctuations generated by the wire rope during its operation in real time. Once the wire rope enters through the feed roller 412 and passes through the support guide groove 414, it is guided from the end of the support guide groove 414 to the surface of the guide roller 42 for continued transmission.

[0056] During operation, the steel wire rope first enters the material input assembly 4 through the feed roller 412. The rolling design of the feed roller 412 guides the steel wire rope to smoothly enter the support guide groove 414. In the support guide groove 414, the steel wire rope is constrained by the ribs to maintain a stable travel trajectory. Due to the sliding fit between the support panel 413 and the pallet frame 415, when the steel wire rope experiences tension fluctuations or changes in running direction, the support panel 413 can adaptively adjust its position to buffer the force changes on the steel wire rope. At the same time, the fluctuation detection sensor 416 continuously monitors the status of the pallet frame 415. Once an abnormal fluctuation is detected, the signal is fed back to the control system, which can adjust the subsequent steering tensioning assembly 5 and the like accordingly. Finally, the steel wire rope is led out from the end of the support guide groove 414 to the surface of the guide roller 42, completing the transmission process in the material input assembly 4.

[0057] The feed roller 412 and support guide groove 414 cooperate to provide initial guidance and restraint for the wire rope. The sliding structure of the support panel 413 and the pallet frame 415 creates a buffering mechanism for changes in wire rope tension. The fluctuation detection sensor 416 provides real-time monitoring data to the system, enabling the entire freight elevator to dynamically adjust according to the wire rope status. This design combines mechanical structure with sensing technology to ensure the stable operation of the wire rope from multiple levels, further ensuring the stability of the freight elevator's operation. This allows the freight elevator to provide a more stable and safe transportation environment for goods.

[0058] Example 3: Based on the contents of the above embodiment, the specific implementation structure of the steering tensioning assembly 5 is designed as follows:

[0059] The frame base plate 521 is securely fastened to the frame of the hoisting base 3, providing a stable mounting platform for the entire assembly. The mounting bracket frame 522 welded to the surface of the frame base plate 521 forms a neat assembly space for the precise installation of the tensioning roller assembly 52. ​​The tensioning roller assembly 52 consists of a support plate 525, a steering roller 523, and a tensioning roller 524. The support plate 525 is made of a high-strength alloy and precision-machined to ensure a smooth surface, providing stable support for the steering roller 523 and tensioning roller 524. Both the steering roller 523 and tensioning roller 524 utilize a high-strength steel core wrapped in wear-resistant rubber, with anti-slip grooves designed on the surface to effectively increase friction with the wire rope.

[0060] The compression support plate 512 of the compression sensing assembly 51 can be adjusted in position via the compression movable groove 511. High-precision guide rails are incorporated into the compression movable groove 511 to ensure smooth and accurate sliding of the compression support plate 512. The compression support plate 512 acts on the axial side of the end tensioning roller 524, cooperating with the tensioning roller 524 to form a wire rope compression structure. The compression support plate 512 and the compression sensing assembly 51 form a sliding fit through the compression movable groove 511, allowing for flexible adjustment of the wire rope compression spacing based on actual working conditions.

[0061] During operation, the wire rope exiting the material input assembly 4 enters the tensioning roller assembly 52, first changing direction via the steering roller 523 before reaching the tensioning roller 524. During this time, the compression sensing assembly 51 monitors the wire rope tension in real time. If the system detects insufficient or fluctuating wire rope tension, the compression sensing assembly 51 controls the compression support plate 512 to slide within the compression movement slot 511, moving it toward the end tensioning roller 524. This reduces the compression spacing of the wire rope, increases the pressure on the wire rope, and increases the tension. Conversely, if the tension is excessive, the compression support plate 512 slides in the opposite direction, increasing the compression spacing and relieving the pressure on the wire rope. This dynamic adjustment ensures that the wire rope always maintains appropriate tension, ensuring smooth transmission to the revolving clamping roller assembly 6.

[0062] Its technical principle is based on the coordinated operation of mechanical structure and sensor control. The steering roller 523 and tensioning roller 524 of the tensioning roller assembly 52 form the basic steering and tensioning structure, providing physical constraints for the wire rope. The high-precision pressure sensor and displacement sensor built into the compression sensing assembly 51 collect real-time data on wire rope tension and the position of the pressing support plate 512. Based on the preset tension threshold, the control system drives the pressing support plate 512 to slide within the pressing movable groove 511, changing the pressing distance between the wire ropes to adjust the tension. This closed-loop control mechanism combines mechanical adjustment with intelligent control to achieve precise regulation of wire rope tension.

[0063] The optimized design of the steering and tensioning assembly 5 significantly enhances the elevator's shock absorption and stability. Precise dynamic tension compensation prevents car shake and vibration caused by loose or excessive wire rope tension, ensuring the elevator remains stable during ascent and descent. The wear-resistant steering roller 523 and tensioning roller 524, combined with an adjustable press-fit structure, reduce frictional losses between the wire rope and the assembly, minimizing the possibility of energy generated by frictional vibration being transferred to the car.

[0064] Example 4: Based on the contents of the above examples, this example describes in detail the structural details of the turnover clamping roller assembly 6, the supporting roller group 71, the steering supporting roller 8 and the buffer compensation assembly, and then explains the process of their coordinated operation:

[0065] The revolving clamping roller assembly 6 is located below the steering tensioning assembly 5 and is the core component for achieving secondary tensioning of the wire rope. The clamping roller bracket body 61 adopts a high-strength steel structure and is firmly connected to the lifting base 3 by bolts, providing reliable support for the entire assembly. The cable clamping roller 63 is assembled on the clamping roller bracket body 61. Its surface is wrapped with a rubber layer with a high friction coefficient, which can effectively increase the friction between it and the wire rope to ensure the tensioning effect. The clamping roller drive device 62 and the cable clamping roller 63 form a transmission connection through a transmission belt or a gear set. According to the control system instructions, the speed and torque of the cable clamping roller 63 can be accurately adjusted to achieve dynamic control of the wire rope tension, so that the wire rope is secondary tensioned when passing through this assembly.

[0066] The supporting roller assembly 71 consists of a fixed frame 711, a supporting frame 712, and positioning supporting rollers 713. The fixed frame 711 is welded to the sidewalls of the car roof frame 2, providing a stable mounting base for the supporting roller assembly 71. The supporting frame 712 is assembled to the fixed frame 711 with high-strength bolts, allowing for flexible layout, installation, and commissioning of the positioning supporting rollers 713. The positioning supporting rollers 713 have a hardened surface that can withstand the heavy pressure of the wire rope and reduce wear.

[0067] The steering support rollers 8 are symmetrically located axially on either side of the cable clamping roller 63 and the positioning support roller 713, demonstrating a sophisticated design. One end of the support link 81 is fixed to the car roof frame 2, while the other end is connected to the movable roller 82 via a high-precision bearing, ensuring its flexible rotation. A metal retaining ring 83 at the end of the movable roller 82 prevents the wire rope from dislodging during steering, ensuring the accuracy and stability of the wire rope's path.

[0068] The buffer compensation assembly is installed in the calibration compensation groove 9 and is mainly composed of a fixed base plate 91, a compensation drive seat 92, a compensation drive shaft 93, a swing arm 94 and an inner support roller 95. The fixed base plate 91 is firmly fixed to the bottom of the calibration compensation groove 9 by embedded bolts, providing stable support for the entire assembly. The compensation drive seat 92 is installed on the fixed base plate 91 and has a built-in drive motor and transmission mechanism, which can drive the swing arm 94 to rotate through the compensation drive shaft 93. The inner support roller 95 mounted on the surface of the swing arm 94 is arranged perpendicular to the compensation drive shaft 93 and is used to change the direction of the wire rope. In addition, the light bar sensor 97 set on the surface of the fixed base plate 91 forms an optical path coupling with the identification element 96 mounted on the swing arm 94. The angular displacement of the identification element 96 generated by the rotation of the swing arm 94 can trigger the signal feedback of the light bar sensor 97, providing real-time monitoring data for the system.

[0069] During operation, the wire rope output from the steering tensioning assembly 5 enters the revolving clamping roller assembly 6. Driven by the clamping roller drive device 62, the cable clamping roller 63 performs secondary tensioning on the wire rope. The wire rope then undergoes initial deflection via the movable roller 82, enters the calibration compensation groove 9, and undergoes secondary deflection around the inner support roller 95. During this process, the compensation drive base 92, based on feedback from the light barrier sensor 97 and the identification element 96, adjusts the angle of the swing arm 94 via the compensation drive shaft 93, causing the inner support roller 95 to adjust the wire rope tension. Finally, after a further deflection via the other side movable roller 82, the wire rope enters the positioning support roller 713, completing the entire transmission path.

[0070] The revolving clamping roller assembly 6 actively adjusts the wire rope tension through the clamping roller drive 62. The support roller assembly 71 and the steering support roller 8 form a stable support and guide structure, ensuring the accuracy of the wire rope's running trajectory. The buffer compensation assembly uses the light barrier sensor 97 and the identification element 96 to monitor changes in wire rope tension in real time. The compensation drive base 92 drives the swing arm 94 to adjust the position of the inner support roller 95, dynamically compensating for wire rope tension. These components work together to form a closed-loop control system, achieving precise control of wire rope tension and operating status.

[0071] The secondary tensioning function of the revolving clamp roller assembly 6 and the dynamic adjustment of the buffer compensation assembly effectively prevent swaying of the freight elevator car due to wire rope tension fluctuations, significantly improving the smoothness of the freight elevator's operation. The precise guidance and support of the steering support roller 8 and support roller group 71 reduce friction and wear between the wire rope and other components, minimizing the potential for vibration. Furthermore, the monitoring and feedback mechanism of the light barrier sensor 97 and the identification element 96 enables the system to quickly respond to changes in wire rope status and make timely adjustments and compensation, further enhancing the stability and reliability of the freight elevator's operation and providing a safe and stable environment for cargo transportation, making it particularly suitable for the efficient transportation of vibration-sensitive goods.

[0072] The above-mentioned implementation structure of this embodiment cooperates with the material input component 4 and the steering tensioning component 5, and has real-time monitoring and automatic adjustment functions, so that the freight elevator can adapt to different loads and operating conditions, enhances the reliability and stability of the freight elevator operation, and provides a safer and more stable environment for cargo transportation. It is especially suitable for the handling of heavy goods and precision goods that require extremely high transportation stability.

[0073] In one case of this embodiment, the support frame body 712 is made of high-strength alloy material and is firmly assembled on the fixed frame body 711 by high-strength bolts, providing a solid and reliable support foundation for the entire supporting roller group 71. The fine-tuning screw 714 configured thereon has been precisely machined, and the surface has a high-precision thread structure. The fine-tuning screw 714 is connected to the positioning supporting roller 713 through a threaded transmission, and the operator can accurately adjust the axial position of the positioning supporting roller 713 by rotating the fine-tuning screw 714. This design enables the positioning supporting roller 713 to flexibly adjust its position according to different specifications of wire ropes and actual operating conditions, ensuring that the wire rope is always in the best supporting state during the transmission process, laying the foundation for the subsequent stable operation of the anti-sway limit frame 72.

[0074] Example 5: Based on the contents of the above embodiment, the specific implementation structure of the anti-sway limiting frame 72 is designed as follows:

[0075] Mounting base plate 721 is securely fastened to the side of supporting roller assembly 71. Made of thickened steel, it is connected to supporting roller assembly 71 via welding or high-strength bolts to form a stable integral structure, providing reliable mounting support for the entire anti-sway limiting frame 72. Movable support rods 722 extend through mounting base plate 721, employing a high-precision sliding fit with the mounting base plate, allowing them to slide flexibly under the guidance of mounting base plate 721.

[0076] The limiting mechanism 723 assembled at the end of the movable support rod 722 is the core component of the anti-sway limiter. The limiting sleeve hole 724 opened on the limiting mechanism 723 has a precisely designed size and shape, which can closely fit the specifications of the wire rope and provide a precise limiting guide for the wire rope. The extended end of the movable support rod 722 extends to the inner cavity of the car top frame 2. The bottom slider 731 assembled at the end is made of wear-resistant material and can slide smoothly on the track of the inner cavity of the car top frame 2. The traction frame 732 fixed to the surface of the bottom slider 731 is connected to the drive shaft of the adjustment motor 733 through the linkage slider 734. The adjustment motor 733 is fixedly arranged in the inner cavity of the car top frame 2. It has high-precision speed and torque control capabilities, and can accurately convert rotational motion into linear displacement of the limiting mechanism 723, thereby realizing dynamic adjustment of the limit coordinates.

[0077] When the freight elevator is in operation, the axial position of the positioning support roller 713 is adjusted by rotating the fine-tuning screw 714 according to the wire rope specifications and operational requirements, ensuring the wire rope is properly supported. During operation, the adjustment motor 733 receives real-time instructions from the control system and drives the linkage slider 734 based on the actual operating state of the wire rope (such as tension changes and sway amplitude). The linkage slider 734 drives the traction frame 732, which in turn pulls the bottom slider 731 to slide within the interior of the car top frame 2. This, through the movable support rod 722, causes the limiter mechanism 723 to produce linear displacement.

[0078] The axial adjustment of the positioning support roller 713 is achieved by screw transmission to ensure the accuracy of the initial position of the wire rope. The anti-sway limit frame 72 is based on the principles of mechanical transmission and automatic control. The adjustment motor 733 is used as the power source. Through the transmission system composed of the linkage slider 734, the traction frame 732 and the bottom slider 731, the rotational motion is converted into linear motion, driving the limiting mechanism 723 to move. The limiting mechanism 723 limits the wire rope through the limiting sleeve hole 724, monitors and dynamically adjusts the position of the wire rope in real time, and quickly adjusts the limit coordinates when it detects that the wire rope has a tendency to sway, limiting the sway range of the wire rope and ensuring the stable operation of the wire rope.

[0079] In terms of stability, the fine-tuning screw 714 adjusts the positioning roller 713, and the dynamic limiting mechanism 723 effectively eliminates sway caused by factors such as wire rope installation deviation and tension changes during operation. In terms of applicability, the adjustable positioning roller 713 and the dynamically adjustable limiting mechanism 723 can adapt to the operation requirements of wire ropes of different specifications and different operating conditions. Whether it is heavy-load freight transportation or light-load high-speed operation, they can effectively play a role in preventing sway and limiting the position, broadening the application range of freight elevators.

[0080] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced therein.

[0081] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method includes only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
