Description

Technical Field

[0001] The present application relates to the technical field of lifting tools, and in particular to a detachable lifting device for lifting heavy objects in a cabin. Background Art

[0002] Lifting devices allow heavy objects to be moved and positioned in different working environments in an efficient and fast manner. This is especially important for industries that require frequent handling of large or heavy objects, such as construction, manufacturing, and large machinery maintenance. By using suitable lifting devices, the time and labor requirements for material handling can be greatly reduced, thereby significantly improving the progress and efficiency of the overall project. In addition, the correct use and maintenance of lifting devices can extend the life of the equipment, reduce the risk of accidental damage due to failure or improper operation, and further save repair and replacement costs. The use of lifting devices is directly related to the safety of the job site. High-quality and safety-compliant lifting equipment can reduce accidents at work, such as falling materials, equipment collapse, etc., and protect the safety of operators and surrounding personnel. Modern lifting devices take into account the needs of various working environments, including indoors, outdoors, confined spaces or severe weather conditions.

[0003] In the wind power industry, the repair and replacement of yaw motors is a routine but challenging task, especially when working inside the nacelle of a wind turbine. Traditionally, such operations use a tripod to lift and position heavy objects. The lifting tripod in the prior art mainly consists of support legs and a top connection point. The tripod is usually composed of three support legs, which are usually of fixed length and are used to provide a stable foundation. The design of the support legs allows the frame to support heavy loads relatively stably on various ground surfaces. The three support legs converge at the top, where there is usually a connection point for mounting a hook or other lifting device to hang or position heavy objects. At the bottom of the support legs, small foot pads or wheels are sometimes provided to enhance stability and a small amount of mobility. When the tripod is in use: It is placed where the lifting operation is required. The support legs are unfolded to ensure solid support on different ground surfaces. The hook or other lifting device is fixed through the top connection point, and then the lifting device is connected to the heavy object to be lifted.

[0004] However, most of the existing tripod supports are fixed structures. These supports are usually bulky, not only difficult to quickly deploy inside the cabin, but also difficult to transport through the narrow passages of the tower. Therefore, a hoisting device is urgently needed to solve the technical problem of poor flexibility of the existing hoisting tripod. Utility Model Content

DETAILED DESCRIPTION

[0029] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0030] In the wind power industry, hoisting operations usually rely on tripod supports, which are composed of three supporting legs and a hook on the top for mounting hoisting equipment. This type of tripod support is mostly a fixed structure. Although it provides basic stability, it shows limitations in specific environments such as wind turbine towers. Due to their large size and fixed structure, these supports are difficult to deploy quickly inside the narrow and height-restricted wind turbine nacelle, and are also difficult to transport through the narrow passages of wind turbine towers. This design not only increases the complexity of the operation, but also affects the efficiency of the operation. Especially in situations where emergency maintenance or efficient operation is required, the existing tripod supports cannot meet the requirements of modern wind power facilities for the flexibility and convenience of hoisting equipment.

[0031] In view of the above technical problems, the embodiment of the utility model provides a detachable lifting device for lifting heavy objects in the cabin, aiming to improve the flexibility, portability and adaptability of the lifting device. In view of the problem that the supporting structure in the prior art is usually fixed and difficult to adapt to different working environments. The supporting mechanism of the present application includes telescopic support rods, which are easy to adjust and can be quickly expanded or retracted according to the working requirements. In addition, each component of the telescopic support rod is easy to disassemble and reassemble, so that the entire device can be easily transported to the inside of the wind turbine cabin through a narrow passage and quickly deployed. And the telescopic support rods are connected by a safety chain, which further enhances the stability and safety of the overall structure. A connecting component is provided on the base, so that the telescopic support rods can be flexibly added or reduced according to actual needs. This variably configured lifting device enhances its applicability and flexibility of use, and can adjust the number of required telescopic support rods according to different working environments and load requirements. The bottom of the telescopic support rod is equipped with a universal wheel with a brake function. The universal wheels provide additional maneuverability and stability, allowing the device to move smoothly on various surfaces. At the same time, the brake system can quickly fix the position when necessary to prevent movement or sliding due to uneven ground or operational errors, thereby increasing the safety of the operation process.

[0032] The hoisting device of the present application is suitable for a variety of industrial and construction environments, especially in scenarios that require high flexibility and adjustability. Specific application scenarios include but are not limited to the wind power industry, in which the internal space of the wind turbine cabin is narrow and the height is limited. The present application can quickly adapt to this complex environment through its modular support structure and adjustable telescopic support rods, and provide stable hoisting operations. In addition, the universal wheel with a brake function enables the device to be safely moved and positioned in the wind turbine tower, enhancing the safety and convenience of operation. In addition, the present application is also applicable to construction sites and heavy industrial settings, such as steel mills or shipyards, which often require the movement and hoisting of large structures or heavy objects. The flexible support configuration allows the operator to quickly adjust the device settings according to the specific task requirements, thereby completing the hoisting task efficiently and safely. In emergency rescue or temporary projects, heavy equipment and materials often need to be deployed quickly. The rapid installation and disassembly capabilities provided by the embodiments of the present application can respond quickly to meet the needs.

[0033] In order to make the above-mentioned purposes, features and advantages of the embodiments of the utility model more obvious and easy to understand, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0034] The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0035] like Figures 1 to 3 As shown, an embodiment of the utility model provides a detachable lifting device for lifting heavy objects in the cabin, and the lifting device is intended to improve the flexibility and safety of lifting. The lifting device includes a base 10, a supporting mechanism and a lifting mechanism. A connecting assembly 101 is installed on the bottom surface of the base 10, and the top of the supporting mechanism is connected to the base 10 through the connecting assembly 101. The connecting assembly 101 is provided with a plurality of connecting heads, and the plurality of connecting heads are arranged circumferentially on the base 10. This layout not only enhances the stability of the entire device, but also effectively disperses the load pressure during the lifting process, thereby improving the operational safety and durability of the equipment.

[0036] Further, regarding the connection assembly 101, a specific embodiment is provided herein. The connection assembly 101 includes two first connectors 1011, and one first connector 1011 is correspondingly provided with two second connectors 1012, and the two first connectors 1011 and the four second connectors 1012 are all arranged near the end of the base 10. This layout enhances the connection efficiency and mechanical balance of the entire device. The two first connectors 1011 are arranged symmetrically along the center of the base 10. This not only makes it easy for the connector to access the support mechanism, but also optimizes the distribution of force due to the symmetry of its position, so that the pressure generated during the lifting operation can be evenly dispersed, thereby reducing the load pressure at a single point. The two first connectors 1011 are placed symmetrically along the center of the base 10 to ensure the balance of the device. The first connector 1011 and the two second connectors 1012 corresponding to it are evenly arranged on the bottom surface of the base 10, and the two second connectors 1012 are symmetrically arranged. It helps to ensure that each part is evenly stressed during the lifting process. It meets the needs for accurate control and structural stability in complex lifting tasks, especially when handling heavy or large items. Through symmetrical settings, the occurrence of tilting or severe wear caused by uneven connection or unbalanced torque can be effectively reduced. By evenly arranging the connectors on the bottom surface of the base 10, this balanced mechanical layout also makes it easier for the device to adapt to different working scenarios, whether it is flat or uneven ground, it can maintain good stability and operational flexibility. Through the connection component 101, the lifting device not only improves its structural stability and operational safety, but also optimizes its adaptability, which can better meet the lifting requirements of various industrial fields.

[0037] The support mechanism includes at least three telescopic support rods 201. The adjustability of the telescopic support rods 201 can adjust the support height and span according to the needs of the specific working environment to adapt to different working scenes. One end of the telescopic support rod 201 is detachably connected to the connector of the connecting assembly 101 by bolts, and the other end is provided with a universal wheel 202 with a brake function. In addition, multiple telescopic support rods 201 are evenly arranged on the base 10, so that the support mechanism not only provides great flexibility in position adjustment, but also can quickly stabilize the device at any time through the brake function to prevent movement or sliding during the hoisting process, thereby ensuring the accuracy and safety of the operation. Two adjacent telescopic support rods 201 are connected by a safety chain 40. This not only enhances the integrity of the structure, but also prevents accidental loosening or collapse to a certain extent, providing additional safety protection for the entire hoisting process. The use of the safety chain 40 ensures that the support structure can remain stable even under extreme conditions.

[0038] Specifically, the telescopic support rod 201 includes at least one supporting outer rod 2011, at least one supporting inner rod 2012 and a plurality of fixing bolts 2013. The supporting outer rod 2011 is slidably sleeved on the outer side of the supporting inner rod 2012. The structural arrangement of the supporting outer rod 2011 and the supporting inner rod 2012 enables the supporting rod to adjust its length according to actual needs. The supporting outer rod 2011 is in the form of a sliding sleeve, sleeved on the outer side of the supporting inner rod 2012, that is, the supporting outer rod 2011 is freely telescopic on the supporting inner rod 2012, thereby adjusting the length of the overall telescopic support rod 201. This telescopic mechanism is suitable for occasions where stable support is required at different heights or under different ground conditions. A plurality of through holes are correspondingly arranged on the supporting outer rod 2011 and the supporting inner rod 2012, and the fixing bolts 2013 pass through the through holes of the supporting outer rod 2011 and the through holes of the supporting inner rod 2012 to limit the supporting outer rod 2011 and the supporting inner rod 2012. The plurality of through holes correspondingly arranged on the supporting outer rod 2011 and the supporting inner rod 2012 allow the fixing bolt 2013 to pass through, thereby fixing the two rods together. By selecting different through hole combinations, the length of the supporting rod can be set, and once the setting is completed, the fixing bolt 2013 ensures the stability of the setting, prevents the rod from accidentally sliding during operation, and provides additional safety protection. This limiting mechanism not only provides reliable physical locking, but also allows quick and easy adjustment, supporting efficient on-site operation. The fixing bolt 2013 usually adopts an easy-to-operate manual tightening method, so that it can be adjusted without special tools, which is convenient for on-site staff to quickly adapt under different working conditions. In summary, the telescopic support rod 201 effectively achieves a balance between operational flexibility and stability by combining the sliding sleeve structure and the fixing bolt 2013 limiting mechanism. On the premise of ensuring safety and efficiency, it can flexibly respond to various lifting requirements, especially in working environments with space restrictions or uneven ground, showing good adaptability and reliability.

[0039] Furthermore, a connecting ring is provided on the outer wall of the supporting outer rod 2011, and buckles are provided at both ends of the safety chain 40, and the safety chain 40 is connected to the connecting ring through the buckles. The connecting ring is located on the outer wall of the supporting outer rod 2011, providing a solid fixing point for attaching the safety chain 40. The connecting ring is usually made of high-strength material and can withstand significant tensile force, ensuring that the connection of the safety chain 40 is stable and reliable during the lifting operation. The position and number of the connecting rings are adjusted according to the length and load threshold of the telescopic supporting rod 201 to evenly distribute the force during the lifting process and reduce the pressure on a single point. The application of the safety chain 40 is to further enhance the safety of the structure. The safety chain 40 is equipped with a buckle, which is designed to be easy to operate but not easy to open accidentally, ensuring that the safety chain 40 will not fall off during the lifting operation. Through the buckle, the safety chain 40 can be quickly and firmly connected to the connecting ring of the supporting outer rod 2011. The role of the safety chain 40 is not limited to enhancing the physical stability of the lifting device, but also includes providing additional safety protection under extreme conditions. For example, when performing hoisting operations in windy or other dynamic environments, the safety chain 40 can prevent the support rod from moving or tilting due to vibration or impact, thereby preventing possible equipment damage or operating accidents. In this way, the combination of the connecting ring and the safety chain 40 not only improves the structural integrity of the entire hoisting device, but also enhances safety during operation.

[0040] The hoisting mechanism includes a driving component and a hoisting component, one end of the hoisting component is connected to the base 10, and the other end is connected to the hoisting object, and the driving component is connected to the hoisting object through the hoisting component. Among them, the driving component provides the necessary power to control the hoisting process. One end of the hoisting component is connected to the base 10 structure, and the other end is directly connected to the object to be hoisted, forming a stable and reliable hoisting structure. Through the operation of the driving component, the hoisting object can be lifted or moved to a specified position, thereby achieving efficient and safe material handling. The entire hoisting mechanism not only takes into account the convenience of operation, but also fully considers safety and reliability to ensure that high performance can be maintained under various working conditions. In summary, the hoisting device can provide a flexible hoisting solution for heavy object hoisting operations in various industrial and construction environments. It improves operating efficiency and reduces potential safety risks, meeting the needs of modern industry for efficient and safe hoisting.

[0041] Specifically, the driving assembly adopts a control winch 602 driven by a motor, and the motor drive makes the winch operation more stable and the control more accurate, so as to meet the hoisting requirements of objects of different weights. In addition, the characteristics of the motor drive include fast response and high torque output, which can meet the requirements for quickly adjusting the hoisting height and position. The hoisting assembly includes a fixed pulley and a hoisting hanger, and the fixed pulley is installed on the bottom surface of the base 10, which plays a role in changing the direction of the steel cable and reducing friction, so that the steel cable can run smoothly during the hoisting process, reducing the risk of wear and damage caused by friction. The hoisting hanger is connected to the control winch 602 through the fixed pulley, and the control winch 602 is installed on any telescopic support rod 201, and the control winch 602 and the fixed pulley are connected by a steel cable, which can adjust the specific position of the control winch 602 according to the actual working environment and needs, providing application flexibility. The steel cable extends from the winch to the fixed pulley, and then guides to the hoisting hanger through the pulley, forming a complete force transmission chain. The hoisting pendant is installed at one end of the steel cable, and the other end of the steel cable is fixed on the control winch 602, forming a closed-loop control system, which enhances safety and reliability. Among them, the steel cable is made of high-strength material to withstand high loads and wear caused by long-term operation. Through the drive component and the hoisting component, the hoisting device can effectively improve work efficiency while ensuring the safety and stability of the operation process.

[0042] Furthermore, the lifting pendant is one of a hook or a ring 601. Each pendant is suitable for a specific type of lifting requirement, which enhances the applicability and flexibility of the device. Among them, the hook is one of the most common lifting pendants, which is usually used to quickly and easily connect various lifting belts, ropes or chains. The hook is usually arc-shaped or question mark-shaped, with a safety bayonet at the end to prevent the hung items from accidentally falling off during the lifting process. The ring 601 provides a more fixed and safe connection point, which is suitable for lifting operations that require more stable support. The ring 601 is usually used for heavier or larger items and needs to be fixed to the load by bolts or welding. Choosing a suitable lifting pendant can ensure the smooth progress of the lifting operation. The operator selects the most suitable type of pendant according to the type, weight and characteristics of the hoisted object, thereby improving the safety and efficiency of the operation.

[0043] In a specific embodiment, on the basis of the above embodiment, the support mechanism of this embodiment includes three telescopic support rods 201, any one of the telescopic support rods 201 is connected to the first connector 1011, and the two second connectors 1012 corresponding to the first connector 1011 are respectively connected to the other two telescopic support rods 201. Each telescopic support rod 201 can be adjusted in length according to the operation requirements. Whether it is operating in a narrow space or in a complex environment requiring a specific support configuration, it can quickly adapt to different operating conditions, thereby improving its practicality. Regarding the connection method, one telescopic support rod 201 is directly connected to the first connector 1011, while the other two telescopic support rods 201 are respectively connected to the corresponding two second connectors 1012. This triangular layout makes the force distribution more uniform, enhances the stability of the entire support structure, and improves the stability and carrying capacity of the entire hoisting device during operation. When hoisting heavy objects, through this uniform force distribution, any potential tilt or instability caused by uneven load can be effectively reduced to ensure the safety of operation.

[0044] In another specific embodiment, on the basis of the above embodiment, the support mechanism of this embodiment includes four telescopic support rods 201, and the four telescopic support rods 201 are respectively connected to four second connectors 1012. The support mechanism is further optimized, including four telescopic support rods 201, each of which is independently connected to a second connector 1012. This four-point support layout further enhances the stability and balance of the entire lifting device. The layout of the four telescopic support rods 201 provides a solid foundation. The independent adjustability of the four telescopic support rods 201 allows each support rod to adjust its length according to specific operational requirements to provide stable support. Whether it is necessary to increase the support to adapt to a higher lifting position, or to shorten the support to work in a limited space, it can be quickly adapted, increasing the application flexibility and practicality of the device.

[0045] In order to improve the safety and reliability of the hoisting device, the hoisting device also includes a load indicator 50, which can not only monitor the hoisting load in real time, but also help prevent overloading, thereby avoiding possible accidents and equipment damage. The detection end of the load indicator 50 is connected to the hoisting object through the hoisting assembly. The load indicator 50 is based on high-precision sensing technology, and its detection end is directly connected to the hoisting assembly. This end usually contains a sensor for real-time monitoring and recording the weight of the mounted object. These data capture the tension changes during the hoisting process through the sensor, so as to accurately calculate the actual weight of the hoisted object. In this way, structural failure caused by a load exceeding the carrying capacity of the hoisting equipment is prevented. The display end of the load indicator 50 is set on the end side wall of the base 10. The purpose of this is to ensure that the operator can easily see the load data and obtain important information without leaving the operating position. The display end usually includes a digital or analog display that can display the weight of the current load, and sometimes also includes a warning signal or indicator light to prompt the operator whether the load status is safe. In addition, the load indicator 50 also takes into account the convenience of user operation. The interface of the display terminal is simple and easy to understand. The operator can quickly learn how to read and interpret the displayed information, effectively reducing the risk caused by operating errors. When performing hoisting operations, even in complex environments or poor visibility, the operator can clearly understand the real-time weight of the hoisted objects through the display terminal. The load indicator 50 improves the safety and efficiency of hoisting operations.

[0046] Any tilt may lead to uneven load, equipment damage or more serious safety accidents. At least two level bubbles 701 are also installed on the base 10, and the level bubbles 701 are symmetrically installed on the base 10. The function of the level bubble 701 is mainly to provide an intuitive visual reference to confirm that the base 10 of the lifting device remains horizontal before and during lifting. The level bubble 701, also known as a level bubble or a level gauge, can indicate whether the device is in a horizontal state by the position of the bubble in the liquid inside it. It provides a fast, accurate and easy-to-read way to adjust the position of the device. The symmetrically installed level bubble 701 ensures that the horizontal state of the device can be monitored from multiple angles, because a single level bubble 701 may not provide comprehensive horizontal information due to position limitations. By installing at least two level bubbles 701 at symmetrical positions on the base 10, feedback on the horizontal state of the lifting device can be obtained from different perspectives. In addition, the symmetrical installation also helps to eliminate the possible reading error of any one level bubble 701 and provide a more accurate confirmation of the overall horizontal state. Further, the use of the level bubble 701 also simplifies the initial setup and daily maintenance inspection of the equipment. The operator can quickly check the level bubble 701 to confirm that the equipment has been correctly adjusted before starting work, which not only helps to improve work efficiency, but also greatly increases the safety of the operation. In summary, the addition of the level bubble 701 not only enhances the performance and safety of the lifting device in actual operation, but also provides an effective monitoring tool, allowing operators to quickly connect the working status of the lifting device.

[0047] Here, the use process of the hoisting device of the present application is further explained. Before each use, the operator needs to check the hoisting device, including confirming whether all telescopic support rods 201, connectors, universal wheels 202 and their brakes, and hoisting hangers (hooks, rings 601 or grabbers) are intact and working properly. Then, according to the specific hoisting requirements, select the appropriate number of support rods and the type of hoisting hangers. Adjust the length of the telescopic support rod 201 to ensure that the device is stably and balancedly placed in the preset position. Connect the telescopic support rod 201 to the corresponding connector (first or second connector 1012) according to the configuration of the work requirements. Make sure that all support rods are firmly locked in the correct position and use fixing bolts 2013 for additional fixing. Next, move the hoisting device to the starting point of the hoisting, and use the brake function of the universal wheel 202 to fix the device position to prevent movement during the hoisting process. Connect the selected hoisting hanger (hook or ring 601) to the object to be hoisted. Ensure that the connection is safe and there is no looseness or misalignment. Operate the control winch 602 to start the lifting process. The control winch 602 will be driven by a motor to smoothly adjust the length of the steel cable so that the hoisted object can be slowly and steadily raised or lowered to the specified position. Monitor the load indicator 50 throughout the lifting process to ensure that the load does not exceed the safe working limit of the equipment during the lifting process. If there is any abnormality, stop the operation immediately and make adjustments. Slowly lower the hoisted object to the target position and ensure that it is safely placed. Then, disconnect the connection between the lifting pendant and the object and retract the steel cable of the control winch 602. Move the lifting device back to the storage area for cleaning and subsequent inspection to ensure that the device is in good condition and ready for the next use.
