[0027] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0028] like Figure 1 、 Figure 2 As shown, a specific embodiment of the present invention discloses an auxiliary lifting assembly for steel sections, including a support frame 100, a hook 200, an adjustment structure 300, a locking structure 400, and a lifting ring 500; the support frame 100 is provided with a channel 140 running through the two side walls, the number of the hooks is 2, and the two hooks 200 are symmetrically installed at the channel 140, and the hooks 200 slide along the channel 140; the adjustment structure 300 is rotatably installed in the middle of the support frame 100, and is used to drive the two hooks 200 to open and close; the locking structure 400 is installed at the top of the support frame 100, and is used to lock the adjustment structure 300 so that the hook remains in the adjusted position; the bottom two sides of the lifting ring 500 are rotatably installed on the support frame 100.

[0029] The above-mentioned auxiliary lifting assembly for steel sections has a hook that slides along the clamping channel and limits the direction of movement so that it can adapt to the shape of the H-section steel and move. It can also transfer the force of the hook to the support frame, thereby achieving force dispersion and preventing force from being concentrated on a certain component and causing damage. The adjustment structure is used to drive the two hooks to open and close, and can be adjusted to achieve a quick engagement with the H-section steel, and can be easily released later for easy disassembly. In addition, the locking structure is used to lock the adjustment structure so that the hook remains in the adjusted position, effectively maintaining the clamping effect and preventing it from loosening during lifting.

[0030] like Figure 9 As shown, in actual use, it is necessary to clamp the lifting components at both ends of the H-shaped steel, and the lifting rings of the two lifting components are coordinated with the lifting equipment through chains to ensure that the H-shaped steel is lifted and moved smoothly; it should be noted that it is more preferred to install reinforcing ribs on the H-shaped steel to limit the lifting components on both sides of the length direction of the H-shaped steel to prevent the lifting components from moving in the length direction; the use of reinforcing ribs can overcome the problem of damage to the H-shaped steel caused by punching, and can also enhance the structural strength of the H-shaped steel, and can also be better used in conjunction with the lifting components.

[0031] Further, if Figure 3 、 Figure 4As shown, the support frame 100 includes a support base 110, an arch frame 120 is fixedly provided on the top surface of the support base 110, a fourth through-hole is provided in the middle of the top surface of the arch frame, a support tube 130 is fixedly provided on the outer side of the top end of the fourth through-hole, and the shape of the fourth through-hole is adapted to the shape of the inner wall of the support tube; a channel 140 is provided on the support base 110, a first circular hole 150 communicating with the channel is provided in the middle of the top surface of the support base 110, and a first threaded hole 160 is correspondingly provided in the center of the bottom surface of the channel 140;

[0032] like Figure 2 As shown, the adjustment structure 300 includes a turntable 310, a gear 320, and a shaft 330. The gear 320 is arranged inside the channel 140 and meshes with the rack 210 of the hook 200 for transmission. The turntable 310 is arranged inside the arch 120. The shaft 330 is rotatably inserted into the first circular hole 150. The bottom end of the shaft 330 is threadedly connected to the first threaded hole 160. The turntable 310 and the gear 320 rotate with the shaft 330, driving the hook to open and close. The locking structure 400 is installed on the support tube 130. It is used to lock the shaft and realize locking of the hook; by means of the gear rack cooperation, the gear is driven to rotate by the adjustment structure, thereby realizing the opening and closing action of the two hooks, and the operation is simple; wherein, the bottom end of the shaft is threadedly connected with the first threaded hole, providing a downward screw-in and locking effect, so that the shaft will not be easily loosened, maintaining the cooperation between the shaft and the gear and the turntable; the bottom of the lifting ring 500 is rotatably mounted on both sides of the arch frame 120, so that the lifting ring can be swung to the outside without affecting the adjustment operation of other components;

[0033] Among them, the support seat, arch frame, and support tube are an integrated structure, which can ensure that the support frame itself has sufficient structural strength; second threaded holes are provided at both ends of the arch frame, and third through-holes are provided on both sides of the bottom of the lifting ring. The two sides of the bottom of the lifting ring are supported on both ends of the arch frame, and bolts are passed through the third through-holes and threadedly connected with the second threaded holes, so that the bottom of the lifting ring is rotatably mounted on the arch frame;

[0034] Further, if Figure 5 As shown, the shaft 330 includes a first prism block 331, a second prism block 332, a first column 333, a third prism block 334, and a threaded rod 335 connected in sequence; the threaded rod 335 is threadedly connected to the first threaded hole 160; Figure 2 As shown, the center of the gear 320 is provided with a first through hole 321, the shape of the first through hole 321 is adapted to the shape of the third prism block 334; the diameter of the first column 333 is adapted to the aperture of the first circular hole 150; Figure 6As shown, a second through-hole 311 is provided in the middle of the turntable 310. The aperture of the second through-hole 311 is the same as that of the first circular hole. A collar 312 is fixedly provided on the outer side of the top of the second through-hole 311.

[0035] The locking structure 400 is used to hold and lock the first prism block 331 .

[0036] The edge of the turntable extends beyond the outside of the arch frame, and a plurality of vertical rods are fixed on the top edge of the turntable, which serve as gripping parts for adjusting the rotation of the turntable, making it easy to rotate the turntable to adjust the entire adjustment structure and realize the opening and closing of the hook;

[0037] The maximum outer diameters of the second prism block, the first column, the third prism block, and the threaded rod decrease in sequence, and the maximum outer diameter of the second prism block is smaller than the inner diameter of the support tube, ensuring that the shaft can be normally installed and connected with the corresponding components; and it should be pointed out that when the threaded rod is threaded into place with the threaded hole, the hook moves inward to the extreme position to perform an effective clamping effect; under this structural limitation, the threaded rod is rotated upward, and the various sections of the shaft will not interfere with or collide with the holes in the upper position, which will not affect the lifting activity, while also maintaining the required transmission coordination.

[0038] Further, if Figure 7 As shown, the locking structure 400 includes a universal sleeve 410, a spring 420, a pull head 430, and a cover body 440; a pull rod 411 is fixedly provided at the center of the end of the universal sleeve 410, and a third through-hole 441 is correspondingly provided at the center of the cover body 440, and the pull rod 411 is slidably passed through the third through-hole 441; the end of the pull rod 411 extends out of the cover body, and the end is connected to the pull head 430 by a pin; the spring 420 is sleeved on the outside of the pull rod 411, and the spring 420 is clamped between the cover body 440 and the universal sleeve 410, providing a downward pushing force for the universal sleeve; the inner wall of the support tube 130 is a prismatic hole structure, and the outer wall shape of the universal sleeve 410 is consistent with the shape of the support tube 130 The inner wall shape is adapted, and the universal sleeve is slidably arranged at the support tube; the cover body 440 is covered on the support tube 130 and is fixedly connected by bolts; with this structure, in the absence of external force, the spring pushes the universal sleeve downward, so that the universal sleeve is maintained on the outside of the first prism block, so that the force of the shaft is transferred to the support tube through the universal sleeve, and then transferred to the support frame, thereby effectively locking the shaft, making the shaft, turntable, and gear unable to rotate, and the hook is maintained in the required position, providing effective clamping for the H-shaped steel; it should be noted that the universal socket is a socket-type multi-functional wrench structure, which can be purchased and used on the market, and the details will not be repeated.

[0039] Further, if Figure 8 As shown, the hook 200 includes a rack 210, a support plate 220 fixed to one end of the rack 210, an L-shaped plate 230 fixed to the end of the support plate 220, and the L-shaped plate is bent toward the rack; the shape of the support plate is adapted to the shape of the channel, and the support plate slides along the channel; a first limiting post 240 is installed on the top surface of the end of the rack 210 away from the support plate, and a second limiting post 250 is installed on the top of the side of the support plate 220 opposite to the rack; a slot 170 is opened on the top surface of the support seat 110 corresponding to the moving track of the first limiting post 240 and the second limiting post 250; the first The limiting column and the second limiting column are correspondingly threadedly connected and installed on the rack and the support plate. The top surfaces of the first limiting column and the second limiting column are lower than the notch of the slot hole. The hook can be adjusted into position first and then the limiting column is installed to facilitate the overall assembly; the first limiting column and the second limiting column can further limit the movement of the hook to achieve smooth opening and closing movement, and can also prevent the hook from disengaging, so that the rack maintains a meshing state with the gear, ensuring that the hook is driven to achieve the required opening and closing action; and the hook adopts the above structure, which can better transfer the force to the support seat, achieve force dispersion, and prevent damage to the hook.
