Specific implementation manner

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Refer to Figure 1 - Figure 5 As shown in the figure, an embodiment provided by the present invention: A temporary fixing device for an anti-seismic device of a crane, including a base 1, a plurality of conical shells 2 are fixedly connected to the bottom of the base 1, a rotating rod 7 is rotatably connected inside the conical shell 2, two turntables 9 are fixedly connected to the outside of the rotating rod 7, two limiting discs 8 are fixedly connected inside the conical shell 2, an insert floor 12 is slidably connected inside the limiting disc 8, a first sliding rod 11 is slidably connected inside the insert floor 12, a connecting rod 10 is provided between the insert floor 12 and the turntable 9, a winding disc 3 is provided on the top of the base 1, a fixed rope 5 is sleeved outside the winding disc 3, one end of the fixed rope 5 is fixedly connected with a hanging ring 6, the other end of the fixed rope 5 is fixedly connected to the middle side of the top of the base 1, a connecting block 13 is fixedly connected to the outside of the hanging ring 6, and a fixing component is provided on the top of the winding disc 3 for fixing the fixed rope 5.

[0033] Specifically, when a worker installs the device, the conical shell 2 is inserted into the soil. First, the rotating rod 7 is twisted, which drives the turntable 9 to rotate, causing the connecting rod 10 to rotate, and then pulling the insert floor 12 to slide outside the first sliding rod 11, so that the insert floor 12 slides outward inside the conical shell 2 and is directly inserted into the soil. At this time, the hanging ring 6 is unlocked by the fixing component, and then the hanging ring 6 can be installed on the hook of the crane. When the hanging ring 6 is not needed, the fixed rope 5 is wound around the winding disc 3 and fixed by the fixing component to avoid loosening.

[0034] Refer to Figure 2 And Figure 3, The fixing component includes a fixing block 14 and two plug-in blocks 4. The bottom of the fixing block 14 is fixedly connected to the top of the wire winding disc 3. A push rod 18 is slidably connected inside the fixing block 14. A moving plate 17 is fixedly connected to the outside of the push rod 18. The outside of the plug-in block 4 is slidably connected inside the connecting block 13. A rotating block 16 is arranged between the plug-in block 4 and the moving plate 17. Two limiting rods 15 are fixedly connected to the inner wall of the fixing block 14. A second sliding rod 20 is slidably connected inside the push rod 18. A spring 21 is sleeved on the outside of the second sliding rod 20. One end of the second sliding rod 20 away from the moving plate 17 is fixedly connected to an adapter block 19.

[0035] Specifically, push the push rod 18 to slide on the outside of the second sliding rod 20, then drive the moving plate 17 to slide inside the fixing block 14, so that the spring 21 is compressed. At the same time, the rotating block 16 on the outside of the moving plate 17 rotates, and then pulls the plug-in block 4 to slide on the outside of the limiting rod 15 and leave the inside of the connecting block 13. At this time, the connecting block 13 can be pulled, and then the hanging ring 6 is unlocked. At this time, the fixing rope 5 can be taken out outside the wire winding disc 3 and its hanging ring 6 is fixed to the crane. When the fixing rope 5 is not needed, just operate in the reverse direction.

[0036] Refer to Figure 1 - Figure 5 , The outside of the rotating rod 7 is rotatably connected inside the base 1. The outside of the rotating rod 7 is rotatably connected inside the limiting disc 8. One end of the connecting rod 10 is rotatably connected to the outside of the turntable 9. The other end of the connecting rod 10 is rotatably connected to the bottom end of the plug-in floor 12. The outside of the plug-in floor 12 is slidably connected inside the conical shell 2. Both ends of the first sliding rod 11 are fixedly connected inside the limiting disc 8. The inside of the fixing block 14 is slidably connected to the outside of the limiting rod 15. The bottom of the adapter block 19 is fixedly connected to the inner bottom wall of the fixing block 14. One end of the spring 21 is fixedly connected to one side of the moving plate 17, and the other end of the spring 21 is fixedly connected to one side of the adapter block 19. The outside of the connecting block 13 is slidably connected inside the fixing block 14.

[0037] Specifically, the rotating rod 7 maintains a rotation connection inside the base 1 and the limiting disk 8. As a transmission hub of the power source, its rotation directly drives 9 to rotate. One end of the connecting rod 10 is connected to the outside of the rotating disk 9. This design ensures that the movement of the rotating disk can be effectively converted into the movement of the connecting rod 10; the other end is connected to the bottom end of the plug-in floor 12, and the movement of the plug-in floor 12 is driven by the rotation of the connecting rod 10. The plug-in floor 12 is connected to the inside of the conical shell 2 by sliding, so that it can move flexibly inside the conical shell 2. This design ensures that the plug-in floor 12 can be accurately and stably inserted into the soil to complete the fixing function of the device. The two ends of the sliding rod 11 are fixed inside the limiting disk 8, providing a stable support structure for subsequent movement and sliding. The sliding connection between the inside of the fixed block 14 and the limiting rod 15, and the fixed connection between the bottom of the connecting block 19 and the inner bottom wall of the fixed block 14, together constitute a flexible and controllable moving system, so that the spring 21 can provide elastic force when needed, thereby controlling the movement of the connecting block 13. One end of the spring 21 is fixed to one side of the moving plate 17, and the other end is fixed to one side of the connecting block 19. This design enables the spring 21 to generate elastic force under certain conditions, thereby pushing the moving plate 17 to move. The sliding connection between the connecting block 13 and the fixed block 14 is to control the position of the connecting block 13, so as to realize the retraction and extension of the fixed rope 5 to meet different operation requirements.

[0038] Working principle: When performing the installation task of the device, the operator first buries the conical shell 2 deep into the soil. Then, by screwing the rotating rod 7, the driving turntable 9 starts to rotate, and this action drives the connecting rod 10 to rotate accordingly. The rotation of the connecting rod 10 prompts the plug-in plate 12 to slide along the periphery of the sliding rod 11, and at the same time, it continues to slide outward inside the conical shell 2, and finally achieves direct contact with the soil and stable embedding. Next, the push rod 18 is pushed to slide on the periphery, and this action not only drives the movement of the moving plate 17 inside the fixed block 14, but also puts the spring 21 in a compressed state. At the same time, the rotating block 16 outside the moving plate 17 also starts to rotate, pulling the plug-in block 4 to slide along the periphery of the limit rod 15 and detaching from the inside of the connecting block 13. At this point, by pulling the connecting block 13, the hanging ring 6 is successfully unlocked, so that the user can easily take out the fixing rope 5 from the periphery of the winding drum 3, and fix its hanging ring 6 on the crane, completing the arrangement of the fixing rope. If the rope 5 needs to be fixed, it can be rolled up and fixed by simply performing the reverse operation according to the above steps to avoid clutter.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
