The described embodiments are only possible technical implementations of the present invention, but are not limited thereto. Other embodiments obtained by those skilled in the art in conjunction with the embodiments of the present invention without creative effort are also within the protection scope of the present invention.

[0017] This application mainly uses a movable hoisting frame for indoor reinforcement and cutting, achieving the effect of flexibly hoisting the components to be cut indoors. The following is a further detailed description of this application.

[0018] Example 1 The movable hoisting frame for indoor reinforcement cutting provided in this application embodiment includes a concrete floor slab 2, a component to be cut 3, a base plate 1, a hoisting component 5, a counterweight component 14, and auxiliary support devices 32. The component to be cut 3 is located within the concrete floor slab 2, and the base plate 1 is positioned above the concrete floor slab 2. Casters 4 are installed below the base plate 1 to facilitate movement of the entire hoisting frame. The hoisting component 5 is located on the same side of the top of the base plate 1 as the component to be cut 3, for lifting the component to be cut 3. A sliding groove 13 and a counterweight component 14 are located on the opposite side of the top of the base plate 1 from the hoisting component 5. The counterweight component 14 can slide on the sliding groove 13, balancing the hoisting frame. Auxiliary support devices 32 are installed on both sides of the base plate 1 to increase the stability of the hoisting frame. Through the cooperation of these components, the effect of flexibly hoisting the component to be cut indoors is achieved, solving the problem of existing hoisting methods being difficult to move flexibly and stably indoors.

[0019] Specifically, the hoisting component 5 includes a base 6 mounted on top of the base plate 1. The base 6 is generally made of sturdy metal and is mostly square in shape, securely fixed to the base plate 1 by bolts or other means. A height adjustment column 7 is mounted above the base 3. The height adjustment column 7 can be hydraulic or telescopic. Taking the telescopic type as an example, it consists of multiple nested tubes of different diameters, and the height is adjusted by the extension and retraction of the tubes. A rotating platform 8 is mounted at the top of the height adjustment column 7. A rotating rod 9 is rotatably mounted on the rotating platform 8. The rotating rod 9 is generally a metal rod connected to the rotating platform 8 and can rotate in a circle on the rotating platform 8. A lifting arm 10 is mounted on the rotating rod 9. The lifting arm 10 can be a steel beam and is straight in shape. A hook 11 is suspended from the top of the lifting arm 10. The hook 11 is generally forged from high-strength steel and is hook-shaped, used to suspend the hoisting rope 12. The bottom end of the hoisting rope 12 is fixedly set on the component 3 to be cut. The hoisting rope 12 can be a steel wire rope with high strength and wear resistance.

[0020] The rotary table 8 has several positioning holes 19, which are circular through holes evenly distributed around its circumference. Positioning rods 20, cylindrical metal rods, are installed in each positioning hole 19. A limiting plate 21, a circular metal plate, is fixed to the rotary rod 9 on the same side as the positioning holes 19. The limiting plate 21 has a limiting hole 22, also a circular through hole. When the rotary rod 9 rotates to the appropriate position, the limiting hole 22 aligns with the positioning hole 19, allowing the positioning rod 20 to be inserted, thus positioning the rotary rod 9.

[0021] A telescopic rod 23 is fitted onto the lifting boom 10. The telescopic rod 23 can be made of aluminum alloy, which is lightweight and has high strength. A fixing hole 24, a circular through hole, is provided at the bottom end of the telescopic rod 23. A pin hole 25, also a circular through hole, is provided on the lifting boom 10. When the telescopic rod 23 slides to a suitable position on the lifting boom 10, the fixing hole 24 aligns with the pin hole 25, and the pin is inserted to fix the position of the telescopic rod 23, thereby adjusting the length of the lifting boom 10.

[0022] The counterweight component 14 includes a counterweight box 15, which is generally a square box made of welded steel plates. Inside the counterweight box 15 are counterweight blocks 16, which can be cast iron blocks and have considerable weight. Inside the counterweight box 15 are partition plates 26, which are generally steel plates, dividing the interior of the counterweight box 15 into multiple placement slots 27. The counterweight blocks 16 are placed in the placement slots 27 for easy management and adjustment. A limit device 17 is provided on one side of the counterweight box 15. The limit device 17 includes a limit block 29 fixedly mounted on the side surface of the counterweight box 15. The limit block 29 is a square metal block. A through-hole limit threaded hole 30 is provided in the limit threaded hole 30, and a limit threaded rod 31 is provided within the limit threaded hole 30. By rotating the limit threaded rod 31, the position of the counterweight box 15 can be limited. A slider 18, typically a metal block, is fixedly connected to the bottom of the counterweight box 15. The slider 18 slides within a groove 13, a strip-shaped channel on the base plate 1, allowing the slider 18 to slide freely and thus adjust the position of the counterweight box 15. A handle 28, typically a metal rod, is located on the side of the counterweight box 15 opposite to the lifting component 5, facilitating the operator's movement of the counterweight box 15.

[0023] The auxiliary support device 32 includes an auxiliary support block 33 fixedly mounted on the side wall of the base plate 1. The auxiliary support block 33 is a square metal block, fixed to the side wall of the base plate 1 by bolts. The auxiliary support block 33 has a through auxiliary threaded hole 34, and an auxiliary threaded rod 35 is installed within the auxiliary threaded hole 34. The auxiliary threaded rod 35 is generally a metal rod with threads on its surface. A support block 36 is installed at the bottom end of the auxiliary threaded rod 35. The support block 36 is generally a circular metal plate, increasing the contact area with the ground and improving the stability of the support. By rotating the auxiliary threaded rod 35, the height of the support block 36 can be adjusted, allowing the auxiliary support device to function better.

[0024] The caster wheel 4 is a caster wheel with a foot pedal self-locking device. This caster wheel can roll easily when it needs to move. When it reaches the designated position, the caster wheel 4 can be locked by stepping on the foot pedal self-locking device to prevent the hoisting frame from moving.

[0025] The implementation principle of this embodiment is as follows: This movable hoisting frame, by incorporating casters 4 beneath the base plate 1, solves the problem of existing hoisting equipment's difficulty in moving flexibly indoors, allowing for rapid adjustment of the hoisting frame's position according to different cutting locations. The height adjustment column 7, rotating platform 8, and rotating rod 9 of the hoisting component 5 enable the lifting boom 10 to operate at different heights and angles, improving hoisting flexibility. The counterweight component 14, by sliding on the slide groove 13, can adjust the position of the counterweight box 15 according to the weight and location of the hoisting, ensuring the balance and stability of the hoisting frame. The auxiliary support device 32 further increases the stability of the hoisting frame and improves the safety of hoisting operations. Compared with existing technologies, this hoisting frame offers better flexibility, stability, and safety in indoor reinforcement and cutting operations, significantly improving work efficiency.

[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
