[0002] A hook-off sling is a device used in lifting machinery to prevent the hooked sling from unhooking and causing accidents. This sling improves the safety and reliability of lifting operations through a specific anti-unhooking design. In modern industrial production, lifting operations are one of the common logistics activities, but they are also accompanied by potential safety risks. In order to ensure the safety of lifting operations, the design and application of hook-off slings are particularly important.

[0003] In the prior art, in the heavy machinery manufacturing industry, especially in the manufacture and assembly of large machine tools and steel rolling equipment, due to the different weights and sizes of various components, traditional slings with fixed lifting point spacing are often difficult to meet these complex and changeable lifting requirements. The design of this fixed lifting point spacing limits the flexibility of the sling, causing frequent shaking during the lifting process, which not only reduces the assembly accuracy, but also increases the difficulty of operation, thereby affecting the overall work efficiency. Instability during the lifting process may also cause equipment damage or assembly errors, further increasing manufacturing costs and rework rates. Therefore, the present application provides a detachable hook sling with adjustable lifting point spacing to meet the needs. Utility Model Content

This not only may cause shaking during the lifting process and reduce assembly accuracy, but also directly affect work efficiency.

[0005] In order to solve the above-mentioned problems, the present invention is implemented through the following technical solutions:

[0006] A detachable hook sling with adjustable hanging point spacing comprises: a hanging frame; a driving mechanism mounted on the hanging frame; a hanging point mechanism arranged on the driving mechanism via a hanging member; a dynamic balance adjustment member mounted on the driving mechanism, the dynamic balance adjustment member being connected to the hanging member, and the hanging member being slidably connected to the driving mechanism via a sliding mechanism; and a sensor body mounted on the hanging frame.

[0023] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of protection of the present invention.

[0024] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention.

[0025] Reference Figure 1 - Figure 6 A detachable hook sling with adjustable hanging point spacing includes: a hanging frame 1; a driving mechanism 3, installed on the hanging frame 1; a hanging point mechanism 5, set on the driving mechanism 3 through a hanging member 4; a dynamic balance adjustment member 7, installed on the driving mechanism 3, the dynamic balance adjustment member 7 is connected to the hanging member 4, and the hanging member 4 is slidably connected to the driving mechanism 3 through a sliding mechanism 8; a sensor body 6, installed on the hanging frame 1.

[0026] The dynamic balance adjustment part 7 is connected to the suspension part 4 to monitor and adjust the center of gravity of the hoisted object in real time during the hoisting process to ensure the balance of the hoisted object. The dynamic balance adjustment part 7 can adjust the lifting point position in time according to the data provided by the sensor body 6 to maintain the balance of the hoisted object, reduce the shaking during the hoisting process, and improve the safety and accuracy of the hoisting.

[0027] The sensor body 6 includes a pressure sensor, an accelerometer or an inclinometer, etc., which is used to monitor key parameters such as the weight distribution and tilt angle of the hoisted object, and transmit these data to the control system. The sensor body 6 provides real-time data support, enabling the control system to adjust the lifting point position in time according to actual conditions to ensure that the hoisted object is always in the best balance state. This design improves the degree of automation of hoisting and reduces the need for manual intervention.

[0028] The driving mechanism 3 includes: a driving member 303; a first gear 304 mounted on the driving member 303; and a second gear 305 rotatably mounted on the suspension frame 1. The first gear 304 is meshed with the second gear 305.

[0029] The rotation of the driving member 303 drives the first gear 304 to rotate, and then transmits power to the second gear 305 through meshing. The gear transmission has a high transmission efficiency and can ensure smooth and stable power transmission. The moving distance and speed of the lifting point mechanism 5 can be accurately controlled through the meshing ratio of the gears, thereby achieving fine adjustment of the lifting point spacing. The gear structure is simple, highly reliable, and can withstand large loads. It is suitable for lifting operations in the heavy machinery manufacturing industry. By adjusting the size and meshing ratio of the gears, it can flexibly respond to different lifting requirements and improve the versatility and adaptability of the sling.

[0030] The driving mechanism 3 further includes: a bidirectional screw rod 302 mounted on the suspension frame 1 ; a third gear 306 mounted on the bidirectional screw rod 302 , and the third gear 306 is meshed with the second gear 305 .

[0031] The rotation of the second gear 305 drives the third gear 306 to rotate, thereby rotating the bidirectional screw rod 302. The rotation of the bidirectional screw rod 302 is converted into linear motion of the slider 1 301 matched therewith, thereby adjusting the spacing between the hanging points.

[0032] The driving mechanism 3 further includes: a slider 1 301 , which is arranged on a bidirectional screw rod 302 , and the slider 1 301 is connected to the suspension member 4 .

[0033] Slider 1 301 converts rotational motion into linear motion by cooperating with the bidirectional screw rod 302. When the bidirectional screw rod 302 rotates, slider 1 301 moves along the bidirectional screw rod 302, thereby driving the suspension member 4 to move, thereby adjusting the spacing between the hanging points. The design of slider 1 301 makes the adjustment of the hanging point position more stable, reduces the shaking caused by uneven movement, and improves the stability during the lifting process. The bidirectional screw rod 302 has a self-locking function, that is, when there is no power input, slider 1 301 will not move on its own due to gravity or external interference, ensuring that the hanging point position is fixed.

[0034] The sliding mechanism 8 includes: a sliding rod 801, which is installed on the sliding block 301; a sliding block 802, which is slidably installed on the sliding rod 801, and the sliding block 802 is connected to the suspension member 4.

[0035] The use of sliding mechanism 8 makes the adjustment of the lifting point position more controllable, reducing safety hazards caused by improper positioning. The design of slider 2 802 ensures that even if the center of gravity of the hoisted object changes during the lifting process, fine-tuning can be used to maintain the balance of the hoisted object, thereby improving the safety of the lifting. The sling can not only achieve a wide range of position adjustment, but also perform fine-tuning to ensure the stability and safety of the hoisted object during the lifting process. This design improves the adaptability and flexibility of the sling, making it very suitable for lifting components of different sizes and weights in the heavy machinery manufacturing industry.

[0036] A locking mechanism is provided between the suspension member 4 and the second slider 802 . The suspension frame 1 is made of high-strength material, and a reinforcing crossbeam 2 is provided on the suspension frame 1 .

[0037] The suspension frame 1 is made of high-strength materials, such as special steel or high-strength aluminum alloy, which ensures the structural strength and durability of the entire sling and is able to withstand various loads generated during the lifting process. The suspension frame 1 serves as the main structure of the entire sling and provides stable support for other components, ensuring the overall stability of the sling during the lifting process. The use of high-strength materials improves the fatigue resistance of the sling and extends the service life of the sling.

[0038] The setting of the reinforced crossbeam 2 further enhances the structural strength of the suspension frame 1, especially when lifting heavy loads, it can effectively disperse stress and avoid structural deformation caused by excessive local force, increase the overall rigidity of the suspension frame 1, and make the sling more stable during the lifting process, reducing the possibility of shaking, and the reinforced crossbeam 2 helps to optimize the load distribution, so that the sling can evenly distribute stress when bearing heavy loads and avoid local overloads.

[0039] The hanging point mechanism 5 includes a telescopic hook 501 and an anti-slip mechanism 502 , which is arranged on the telescopic hook 501 .

[0040] The anti-slip mechanism 502 can ensure that the hoisted object will not fall off the telescopic hook 501 due to shaking or other reasons during the hoisting process, thereby improving the safety of the hoisting. On the basis of the telescopic hook 501 fixing the hoisted object, the anti-slip mechanism 502 is further locked to provide double protection for the hoisted object and ensure the safe fixation of the hoisted object during the hoisting process.

[0041] During use, turn on the control system and start the sensor body 6 to work, monitor the weight distribution and tilt angle of the hoisted object, and adjust the position of the lifting point mechanism 5 through the driving mechanism 3 according to the specific size and weight of the hoisted object until the appropriate lifting point spacing is reached. After the adjustment is completed, activate the locking mechanism to ensure that the lifting point position will not change during the lifting process, hang the hoisted object on the telescopic hook 501, and ensure that the anti-slip mechanism 502 is locked, start the lifting operation, and the sensor body 6 continuously monitors the status of the hoisted object. If the center of gravity of the hoisted object shifts during the lifting process, the dynamic balance adjustment part 7 will fine-tune the position of the hanging point according to the data provided by the sensor body 6 to maintain the balance of the hoisted object, move the hoisted object to the designated position, prepare for unloading, release the locking mechanism, adjust the lifting point position, and slowly lower the hoisted object to ensure that it is placed stably in the designated position.
