Description

Technical Field

[0001] This utility model relates to the field of vehicle manufacturing technology, and in particular to an anti-fall-off hook and an unmanned overhead crane. Background Technology

[0002] The production line for vehicle parts involves multiple lifting stations. These stations use overhead cranes and their hooks to transport the workpieces to various processing equipment. During transport, the workpieces may swing. To prevent them from swaying and falling off the hooks, overhead cranes commonly use anti-fall hooks. However, existing anti-fall hooks are typically spring-loaded, meaning a spring-loaded tongue is hinged to the outside of the hook. When hanging or removing workpieces, the tongue is manually opened, and the spring force closes it. This method is not only cumbersome, time-consuming, and labor-intensive, but also poses safety hazards. On the production line, the next step can only proceed after all workpieces have been hung, resulting in low lifting efficiency. Utility Model Content

[0003] The main purpose of this utility model is to propose an anti-fall-off hook and an unmanned overhead crane, which aims to solve the technical problem that the workpiece hanging and retrieval operations of the existing anti-fall-off hook are cumbersome, time-consuming and labor-intensive, resulting in low hoisting efficiency on the production line.

[0004] To achieve the above objectives, the present invention proposes an anti-detachment hook comprising a hook body, an anti-detachment rod, a Bluetooth module, and a drive assembly. The hook body includes a hook shank, a hook ring, and a hook head. The hook shank, hook ring, and hook head are sequentially connected and form a lifting space. A lifting opening is formed between the hook shank and the hook head, and the lifting opening is located above the lifting space. The upper and lower ends of the anti-detachment rod are a hinge end and a limiting end, respectively. The hinge end is hinged to the hook shank, and the limiting end extends away from the hinge end and into the lifting space. The Bluetooth module is electrically connected to the drive assembly and can connect to an external device via Bluetooth. The drive assembly is connected to the hinge end and can drive the anti-detachment rod to rotate around the hinge end, causing the limiting end to swing within the lifting space to abut or disengage from the hook head, thereby correspondingly closing or opening the lifting opening.

[0005] In one embodiment, a hinge seat is provided on the side of the hook handle facing the hoisting space. The hinge seat has a hinge hole. A hinge shaft is connected to the hinge end. The extension direction of the hinge shaft is perpendicular to the extension direction of the anti-detachment rod. The hinge shaft passes through the hinge hole and rotates with the hinge hole.

[0006] In one embodiment, a mounting portion is formed at the position where the hinge shaft extends out of the hinge hole. The drive assembly includes a drive member, a worm gear, and a worm. The worm is arranged vertically and connected to the output shaft of the drive member. The worm gear is mounted on the mounting portion and is coaxially arranged with the hinge shaft. The worm gear meshes with the worm. The drive member can drive the worm to rotate about vertically, so as to drive the hinge shaft to rotate through the worm gear, causing the anti-detachment rod to rotate relative to the hinge seat.

[0007] In one embodiment, the driving element is a servo motor.

[0008] In one embodiment, a mounting housing is connected to the side of the hinge base away from the hoisting space, and both the Bluetooth module and the drive component are housed within the mounting housing.

[0009] In one embodiment, a battery for powering the Bluetooth module and the driver is disposed within the mounting housing.

[0010] In one embodiment, the hinge seat is integrally formed with the hook body.

[0011] In one embodiment, the downward-facing side of the limiting end forms an abutment surface, which is inclined downwards from outside the hoisting space to inside the hoisting space.

[0012] In one embodiment, the hook and loop have anti-slip textures on the side facing the hoisting space.

[0013] This utility model also proposes an unmanned overhead crane, which uses the aforementioned anti-fall-off hook.

[0014] This utility model proposes an anti-detachment hook and unmanned overhead crane. By incorporating an anti-detachment rod on the hook body, the rod's hinged end is connected to the side of the hook shank facing the lifting space, while its limiting end can swing within the lifting space. This design ensures the anti-detachment rod does not affect the hook body's outer dimensions, resulting in a compact structure. The limiting end of the anti-detachment rod abuts against the side of the hook head facing the lifting space, effectively preventing the workpiece from detaching and guaranteeing the hook's anti-detachment performance. Operators can connect to the anti-detachment hook's Bluetooth module via external devices. Through electrical connection between the Bluetooth module and the drive assembly, the drive assembly rotates the anti-detachment rod, opening or closing the lifting port. Operators can control the lifting port without physically touching the hook, effectively improving automation, reducing manual labor intensity, and enhancing operational safety. External devices can simultaneously connect to multiple Bluetooth modules on multiple anti-drop hooks via Bluetooth and operate the switches of multiple lifting ports in batches, facilitating use at lifting stations on factory assembly lines and effectively improving lifting efficiency.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0020] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0021] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0022] In this utility model, the descriptions of directions such as "up" and "down" are as follows: Figure 1 and Figure 2 The directions shown are for reference only and are used to interpret the location. Figure 1 and Figure 2 The relative positional relationship between the components in the shown posture is such that if the specific posture changes, the directional indication will also change accordingly.

[0023] Existing anti-fall hooks are usually spring-loaded tongue structures, which means that a spring-loaded tongue is hinged to the outside of the hook. When hanging and removing workpieces from the hook, the tongue is opened manually and closed by the spring force. The operation is cumbersome, time-consuming and labor-intensive. On the production line, the next step can only be carried out after all the workpieces have been hung, resulting in low lifting efficiency.

[0024] This utility model proposes an anti-detachment hook, including a hook body 10, an anti-detachment rod 20, a Bluetooth module 30, and a drive assembly 40. The hook body 10 includes a hook handle 11, a hook ring 12, and a hook head 13. The hook handle 11, hook ring 12, and hook head 13 are connected in sequence to form a lifting space 14. A lifting opening 15 is formed between the hook handle 11 and the hook head 13 in the lifting space 14, and the lifting opening 15 is located at the top of the lifting space 14. The upper and lower ends of the anti-detachment rod 20 are hinged ends 2. 1 and limiting end 22, hinge end 21 is hinged to hook 11, limiting end 22 is away from hinge end 21 and extends into lifting space 14; Bluetooth module 30 is electrically connected to drive assembly 40, and Bluetooth module 30 can connect to external devices via Bluetooth, drive assembly 40 is connected to hinge end 21, drive assembly 40 can drive anti-detachment rod 20 to rotate around hinge end 21, so that limiting end 22 swings in lifting space 14 to abut or disengage from hook head 13, so as to close or open lifting port 15 accordingly.

[0025] Please see Figure 1 and Figure 2 , Figure 1 A schematic diagram of the anti-fall-off hook provided by this utility model when the lifting port 15 is closed; Figure 2 This is a schematic diagram of the anti-drop hook provided by this utility model when the lifting port 15 is opened. The hook shank 11 is located above the hook ring 12. The hook shank 11, hook ring 12, and hook head 13 together form a lifting space 14 for accommodating the workpiece. The workpiece can enter and exit the lifting space 14 through the lifting port 15. The anti-drop rod 20 is located at the lifting port 15. The hinged end 21 of the anti-drop rod 20 is hinged to the hook shank 11 near the hook ring 12. The limiting end 22 of the anti-drop rod 20 can abut against the side of the hook head 13 facing into the lifting space 14. It should be noted that the operator can connect to the Bluetooth module 30 of the anti-drop hook via an external device such as a remote control or mobile terminal. The Bluetooth module 30 is electrically connected to the drive assembly 40. Specifically, the Bluetooth module 30 can be electrically connected to the drive assembly 40 via a control circuit. When it is necessary to open the lifting port 15, the operator can operate an external device, such as pressing a switch button on a remote control, to cause the Bluetooth module 30 to control the drive assembly 40 to rotate the anti-detachment rod 20 around the hinge end 21, causing the limiting end 22 to disengage from the hook head 13 and swing towards the lifting space 14, thereby opening the lifting port 15 to facilitate the entry and exit of the workpiece. When it is necessary to close the lifting port 15, the operator can connect the external device to the Bluetooth module 30 via Bluetooth to control the drive assembly 40 to swing the limiting end 22 of the anti-detachment rod 20 outwards from the lifting space 14 until the limiting end 22 abuts against the hook head 13, thereby closing the lifting port 15 and preventing the workpiece from sliding out of the lifting space 14. It should be noted that the Bluetooth module 30, the process of the Bluetooth module 30 controlling the drive assembly 40 via the control circuit, and the Bluetooth connection method between the Bluetooth module 30 and the external device all adopt existing technologies.

[0026] The anti-detachment hook and unmanned overhead crane proposed in this utility model feature an anti-detachment rod 20 on the hook body 10. The hinged end 21 of the anti-detachment rod 20 is hinged to the side of the hook shank 11 facing the hoisting space 14, and the limiting end 22 can swing within the hoisting space 14. This design ensures that the anti-detachment rod 20 does not affect the outer contour dimensions of the hook body 10, resulting in a compact structure. The limiting end 22 of the anti-detachment rod 20 abuts against the side of the hook head 13 facing the hoisting space 14, effectively preventing the workpiece from detaching from the hoisting space 14 and ensuring the anti-detachment performance of the hook. Operators can connect to the Bluetooth module 30 of the anti-detachment hook via an external device. Through the electrical connection between the Bluetooth module 30 and the drive assembly 40, the drive assembly 40 drives the anti-detachment rod 20 to rotate, thus opening or closing the lifting port 15. Operators can control the lifting port 15 without physically touching the anti-detachment hook, effectively improving the automation level of the anti-detachment hook, reducing manual labor intensity, and enhancing operational safety. External devices can simultaneously connect to multiple Bluetooth modules 30 on multiple anti-detachment hooks and batch operate the opening and closing of multiple lifting ports 15, facilitating use in factory assembly line lifting stations and effectively improving lifting efficiency.

[0027] In one embodiment, a hinge seat 16 is provided on the side of the hook handle 11 facing the hoisting space 14. The hinge seat 16 has a hinge hole. The hinge end 21 is connected to a hinge shaft 17. The extension direction of the hinge shaft 17 is perpendicular to the extension direction of the anti-detachment rod 20. The hinge shaft 17 passes through the hinge hole and rotates with the hinge hole.

[0028] Understandably, the hook shank 11 has a hinge seat 16 on the side facing the hoisting space 14. The hinge end 21 is hinged to the hinge seat 16 via a hinge shaft 17, the extension direction of which is perpendicular to the extension direction of the anti-detachment rod 20. When the drive assembly 40 drives the anti-detachment rod 20 to rotate, the anti-detachment rod 20 rotates relative to the hinge seat 16 about the extension direction of the hinge shaft 17. The rotational engagement between the hinge shaft 17 and the hinge hole provides a pivot point for the anti-detachment rod 20, ensuring that the rotation trajectory of the anti-detachment rod 20 is fixed.

[0029] In one embodiment, the hinge shaft 17 extends out of the hinge hole to form a mounting portion. The drive assembly 40 includes a drive member 41, a worm gear 42, and a worm 43. The worm 43 is arranged vertically and is connected to the output shaft of the drive member 41. The worm gear 42 is mounted on the mounting portion and is coaxially arranged with the hinge shaft 17. The worm gear 42 meshes with the worm 43. The drive member 41 can drive the worm 43 to rotate around the vertical direction, so as to drive the hinge shaft 17 to rotate through the worm gear 42, causing the anti-detachment rod 20 to rotate relative to the hinge seat 16.

[0030] Please see Figure 3One side of the hinge shaft 17 is rotatably engaged with the hinge hole, and the other side of the hinge shaft 17 extends out of the hinge hole to form a mounting part. The worm gear 42 is mounted on the mounting part and is coaxially arranged with the hinge shaft 17, allowing the worm gear 42 to rotate coaxially with the hinge shaft 17. The output shaft of the drive member 41 is positioned facing the hinge end 21. The worm 43 is connected to the output shaft of the drive member 41 and extends to the vicinity of the hinge end 21, so that the thread on the worm 43 meshes with the tooth groove on the side of the worm gear 42. When the drive member 41 drives the worm 43 to rotate, the worm 43 drives the worm gear 42 to rotate, thereby driving the hinge shaft 17 to rotate relative to the hinge seat 16. The hinge shaft 17 and the anti-disengagement rod 20 rotate together, thereby realizing the drive member 41 to drive the anti-disengagement rod 20. Through the meshing of the worm gear 42 and the worm 43, the vertical rotation of the output shaft of the drive member 41 can be converted into the horizontal rotation of the hinge shaft 17, realizing the change of the rotation output direction of the drive member 41. By adjusting the meshing ratio between the thread of the worm 43 and the tooth groove of the worm wheel 42, the rotation amplitude and rotation speed of the anti-disengagement rod 20 can be adjusted.

[0031] In one embodiment, the drive element 41 is a servo motor.

[0032] Furthermore, the servo motor utilizes existing technology. By presetting the output angular displacement of the servo motor, it drives the worm gear 43 to rotate, thereby rotating the anti-detachment rod 20. This allows for precise control of the rotation angle of the anti-detachment rod 20, ensuring that it accurately contacts or disengages from the hook head 13 within the lifting space 14. This guarantees the limiting effect of the anti-detachment rod 20 on the workpiece and prevents damage to the hook head 13. The bidirectional rotation of the anti-detachment rod 20 is achieved by rotating the servo motor in either the forward or reverse direction, thus opening or closing the lifting port 15.

[0033] In one embodiment, the hinge 16 is connected to a mounting housing 50 on the side away from the hoisting space 14, and the Bluetooth module 30 and the drive unit 41 are both housed in the mounting housing 50.

[0034] Understandably, the mounting housing 50 is connected to the side of the hinge 16 away from the lifting space 14, and the hinge 16 provides a mounting position for the mounting housing 50. The drive component 41 is housed within the mounting housing 50, and the worm gear 43 is connected to the output shaft of the drive component 41 and extends out of the mounting housing 50. The end of the worm gear 43 extending out of the mounting housing 50 meshes with the worm wheel 42 to convert the rotational output of the drive component 41 into the rotation of the worm wheel 42. The mounting housing 50 houses the Bluetooth module 30, the drive component 41, and the control circuit, providing effective protection for the Bluetooth module 30, the drive component 41, and the control circuit, preventing the electronic components from being corroded by external contaminants, and improving the service life of the electronic components.

[0035] In one embodiment, a battery 60 for powering the Bluetooth module 30 and the driver 41 is disposed within the mounting housing 50.

[0036] Furthermore, both the Bluetooth module 30 and the driver 41 are powered by the battery 60. The mounting shell 50 is detachably connected to the hinge base 16. The battery 60 can be removed and replaced by removing the mounting shell 50. The battery 60 can also be directly connected to an external power supply device through a circuit. The power supply method can be flexibly selected according to the actual use of the anti-drop hook. This will not be elaborated further here.

[0037] In one embodiment, the hinge seat 16 is integrally formed with the hook body 10.

[0038] Understandably, both the hook body 10 and the hinge seat 16 are metal parts. The hook body 10 and the hinge seat 16 are integrally formed to ensure the connection strength between the hook body 10 and the hinge seat 16, eliminate the risk of cracks at the connection interface between the hook body 10 and the hinge seat 16, enhance the overall structural consistency of the anti-drop hook, and ensure the rotational stability of the anti-drop rod 20 under high-frequency rotation, thereby ensuring the smooth opening and closing of the lifting port 15.

[0039] In one embodiment, the downward-facing side of the limiting end 22 forms an abutment surface 23, which is inclined downward from the outside of the hoisting space 14 to the inside of the hoisting space 14.

[0040] It should be noted that the side of the limiting end 22 that abuts against the hook head 13 is the abutting surface 23. The abutting surface 23 gradually approaches the hook head 13 from the outside of the hoisting space 14 to the inside of the hoisting space 14, so that the distance between the abutting surface 23 and the hook head 13 gradually decreases from the outside of the hoisting space 14 to the inside of the hoisting space 14. The abutting surface 23 can provide guidance for the workpiece when it enters the hoisting space 14 through the hoisting port 15, making it easier for the workpiece to enter the hoisting space 14. Furthermore, since the side of the abutting surface 23 that is closer to the inside of the hoisting space 14 abuts against the hook head 13, it can prevent the workpiece in the hoisting space 14 from falling out of the hoisting space 14, thereby effectively preventing the anti-detachment rod 20 from detaching the workpiece.

[0041] In one embodiment, the hook 12 has anti-slip texture on the side facing the hoisting space 14.

[0042] Understandably, when the workpiece is suspended in the hoisting space 14, the workpiece contacts the bottom of the hook ring 12 under the action of gravity. The hook ring 12 is provided with anti-slip texture on the side facing the hoisting space 14, which can increase the friction between the workpiece and the hook ring 12. When the anti-drop hook suspends the workpiece and moves, it reduces the displacement caused by the swaying of the workpiece, thereby improving the stability of the suspended workpiece.

[0043] This utility model also proposes an unmanned overhead crane, which includes the above-mentioned anti-fall hook. The specific structure of the anti-fall hook is as described in the above embodiments. Since this unmanned overhead crane adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0044] Understandably, the unmanned overhead crane uses anti-drop hooks to lift and move workpieces. The anti-drop hooks can effectively prevent workpieces from falling off. The unmanned overhead crane can be equipped with multiple anti-drop hooks at the same time. Multiple anti-drop hooks can be connected to external devices via Bluetooth at the same time. The external devices can control the opening and closing of the lifting ports 15 of multiple anti-drop hooks at the same time, which facilitates the use of the lifting station on the factory assembly line and effectively improves the lifting efficiency.

[0045] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
