[0026] When using this loose parts lifting tool, after grabbing the loose parts through the hook assembly, start the crane to drive the loose parts lifting tool and the loose parts to move upward synchronously. After the gantry lifting steel frame moves, lift the loose parts to the specified position, and then start the crane in reverse to put down the loose parts.

[0027] Considering that after the loose parts are lifted, in the process of the loose parts being driven to move by the gantry hoisting steel frame, the loose parts are prone to shake and hit the staff, posing a safety hazard, therefore, movable grooves 16 are fixedly provided at both ends of the connecting base plate 1, and a slide plate 17 is slidably provided in the movable groove 16, and two telescopic grooves 18 are fixedly provided in the slide plate 17, and a sleeve rod 19 is fixedly provided at the end of the telescopic groove 18, and a telescopic rod 20 is slidably provided in the sleeve rod 19, and a limit plate 22 is fixedly provided at one end of the telescopic rod 20 that movably extends out of the end of the sleeve rod 19, and the limit plate 22 is movably fitted on the end of the connecting base plate 1, and a spring 21 is fixedly provided between the limit plate 22 and the end of the telescopic groove 18, and the spring 21 is sleeved on the outer ring of the sleeve rod 19 and the telescopic rod 20, and the limit plate 22 and the support rod of the external gantry hoisting steel frame are movably fitted;

[0028] Specifically, according to the distance between the support rods of the two gantry lifting steel frames, the position of the limit plate 22 on the movable groove 16 is adjusted so that the two limit plates 22 can clamp the support rod in the middle, thereby avoiding the problem that the loose parts are prone to shaking only under the tension of the steel cable, and solving the problem that the loose parts are prone to shaking and hitting the staff during the movement of the loose parts driven by the gantry lifting steel frame, posing a safety hazard. In addition, in addition to being able to adapt to gantry lifting steel frames of different lengths, and when the width of the support rods of the gantry lifting steel frames is different, through the installation of the spring 21 and the telescopic rod 20, the distance between the two limit plates 22 can be adjusted, thereby adapting to gantry lifting steel frames of different widths, improving the applicability of the loose parts lifting tool, and having a good market prospect.

[0029] Further, the balancing component includes a second lifting ear 12 and a first lifting ear 2, and two of the second lifting ear 12 and the first lifting ear 2 are provided. The two second lifting ears 12 are respectively fixedly provided at the two ends of the top of the connecting substrate 1, and the two first lifting ears 2 are respectively fixedly provided at the two ends of the bottom of the connecting substrate 1.

[0030] Specifically, after the hook assembly grabs the two ends of the loose parts, they are connected to each other through the steel cable and the lifting ring 15. After the crane is started, the loose parts are lifted. Through the installation of the hook assembly, it is not necessary to carefully find the center of gravity of the loose parts, saving lifting time and operation steps, and it is possible to stably lift loose parts of different sizes, solving the problem that it is difficult to find the center of gravity of the loose parts when lifting the loose parts with the existing loose parts lifting tools used for steel frame lifting, which easily causes the center of gravity of the object to shift and tilt after lifting, which is not conducive to the stability of the loose parts lifting;

[0031] After the loose parts are lifted, the weight of the loose parts is shared by the two first lifting ears 2, and then transmitted to the lifting ring 15 and the steel cable through the two second lifting ears 12, so that both ends of the loose parts receive uniform tension, and the center of gravity shift will not cause tilting and shaking, thereby improving the balance of the loose parts lifting.

[0032] Further, the hook assembly includes a fixing rod 5, which is fixedly mounted on the first connecting ring 3 below. A mounting seat 6 is fixedly arranged at the bottom of the fixing rod 5, a fixing seat 7 is fixedly arranged at the bottom of the fixing seat 6, a hook 10 is arranged between the fixing seat 7 and the mounting seat 6, the lower end of the hook 10 is a bent structure, the upper end of the hook 10 is threadedly connected with the mounting seat 6, a first through hole is arranged on the fixing seat 7, the upper end of the hook 10 is adapted to the first through hole, a threaded hole is also arranged on the fixing seat 7, a second through hole is arranged on the upper end of the hook 10, the second through hole, the first through hole and the threaded hole are connected to each other, a bolt 8 is connected between the second through hole and the threaded hole, and a nut 9 is threadedly connected to the outer ring of the bolt 8 that movably extends out of one end of the fixing seat 7;

Considering that the hook 10 is easy to fall off the mounting seat 6, the bolt 8 is inserted into the threaded hole and the second through hole at the upper end of the hook 10 in turn, and then fastened with the nut 9, so as to avoid rotational displacement between the hook 10 and the mounting seat 6 and improve the stability of the installation of the hook 10.

[0034] Furthermore, a limit rod 11 is rotatably provided on the hook 10. By installing the limit rod 11, the loose parts are prevented from falling off the hook 10, thereby improving the safety of the loose parts lifting tool.
