[0002] During the installation process of structural steel crossbeams, especially when the crossbeams need to be hoisted to high positions, a crane becomes an indispensable auxiliary tool. The use of the crane greatly improves the lifting efficiency, simplifies the operation process, and makes the hoisting of heavy components safer and faster.

[0003] However, although the crane brings many conveniences to the hoisting of structural steel crossbeams, there are still some challenges in actual operation. When the crane hoists the structural steel crossbeam to a high place, it is often difficult to directly achieve precise adjustment of the installation angle of the crossbeam. This link usually relies on manual operation by workers, which not only increases the labor intensity but also may make it difficult to guarantee the accuracy during the installation process.

The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0022] An embodiment of the present utility model provides a lifting tool for a structural steel crossbeam, as Figures 1-4 shown, the lifting tool for the structural steel crossbeam includes: a mounting seat 1 installed on a vehicle, a cavity is provided in the mounting seat 1, a first motor 2 is fixedly installed on the bottom inner wall of the cavity, an output shaft of the first motor 2 is rotatably connected to the top inner wall of the cavity, and the output shaft of the first motor 2 extends to the outside of the mounting seat 1; a disc 3 fixedly installed on the output shaft of the first motor 2, a plurality of hydraulic cylinders 4 for lifting are fixedly installed on the disc 3, a same top plate 5 is fixedly installed on output rods of the plurality of hydraulic cylinders 4, and a sliding groove is provided in the top plate 5; a lifting mechanism assembled on the top plate 5 for lifting the structural steel crossbeam.

[0023] In the solution, when using this hoisting tooling to hoist the structural steel crossbeam, first, the hoisting mechanism firmly fixes the structural steel crossbeam to be hoisted. After fixation, the hydraulic cylinder 4 is started to drive the top plate 5 to lift and lower, and then the structural steel crossbeam can be lifted to a suitable height. After adjusting to a suitable height, the first motor 2 is started to drive the disc 3 to rotate. The disc 3 will drive the hydraulic cylinder 4 and the top plate 5 to rotate, and then the structural steel crossbeam can be moved to the approximate position where it needs to be installed. Then, under the use of the hoisting mechanism, the installation angle and position of the structural steel crossbeam can be adjusted, without relying on manual operation by workers. In this way, the labor intensity of workers can be reduced, and the installation accuracy of the structural steel crossbeam can also be improved.

[0024] In a further preferred embodiment of the present utility model, the hoisting mechanism includes: screws 6 rotatably installed on the inner walls of both sides of the sliding groove, and one end of the screw 6 extends to the outside of the top plate 5; a second motor 7 arranged on one side of the top plate 5, and the output shaft of the second motor 7 is fixedly connected to one end of the screw 6; a slider 8 threadedly installed on the screw 6, and the slider 8 is slidably connected to the inner wall of the sliding groove; a box body 9 welded to the bottom of the slider 8, and a third motor 10 is fixedly installed on the inner top wall of the box body 9, and the output shaft of the third motor 10 is rotatably connected to the box body 9; a support plate 11 fixedly installed on the output shaft of the third motor 10, and two winches 12 are fixedly installed at the bottom of the support plate 11; steel wires 13 are arranged on both of the two winches 12; a cross plate 14 fixedly installed on the two steel wires 13, and two clamping members 15 for fixing the structural steel crossbeam are fixedly installed at the bottom of the cross plate 14.

[0025] In this embodiment, the hoisting mechanism is used to hoist the structural steel crossbeam. When in use, first, the two clamping members 15 tightly clamp the structural steel crossbeam to be hoisted. After clamping, the hoisting mechanism can be moved to a suitable position for use by using the hydraulic cylinder 4 and the first motor 2. Then, the second motor 7 is started to drive the screw 6 to rotate. The screw 6 will drive the slider 8 to horizontally slide in the sliding groove, and the slider 8 will drive the box body 9 to horizontally move, and then the horizontal position of the structural steel crossbeam can be adjusted. The two winches 12 are started to wind or unwind the two steel wires 13, and then the installation height of the structural steel crossbeam can be adjusted. After the adjustment is completed, if there are some deviations in the installation angle, the third motor 10 can be started. The third motor 10 will drive the support plate 11 to rotate, and then the angle adjustment of the structural steel crossbeam can be realized. The adjustment is relatively convenient, without relying on manual operation by workers. In this way, the labor intensity of workers can be reduced, and the installation accuracy of the structural steel crossbeam can also be improved.

[0026] In a further preferred embodiment of the present utility model, a telescopic rod 16 is fixedly installed at the bottom of the support plate 11, and the bottom end of the telescopic rod 16 is fixedly connected to the top of the cross plate 14.

[0027] In this embodiment, by using the telescopic rod 16, the stability of the entire lifting mechanism in the vertical direction can be further enhanced. During the lifting process, even if affected by wind or other external factors, the telescopic rod 16 can provide additional support force to prevent the cross plate 14 and the clamping member 15 from shaking, thus ensuring the safe lifting of the structural steel cross beam.

[0028] In a further preferred embodiment of the present utility model, the same limiting rod 17 is fixedly installed on the inner walls of both sides of the sliding groove, and the limiting rod 17 is slidably connected to the slider 8.

[0029] In this embodiment, by using the limiting rod 17, a clear guiding direction can be provided for the movement of the slider 8 in the sliding groove, ensuring the linearity and stability of the movement of the slider 8 in the horizontal direction. This helps to prevent the slider 8 from shifting or shaking during the movement, thereby improving the overall accuracy and reliability of the lifting mechanism.

[0030] In a further preferred embodiment of the present utility model, a first annular groove is formed at the top of the mounting seat 1, and a plurality of first connection blocks 18 are slidably installed on the inner wall of the first annular groove. The tops of the plurality of first connection blocks 18 are all fixedly connected to the bottom of the disc 3.

[0031] In this embodiment, the sliding connection mode between the first annular groove and the first connection blocks 18 makes the connection between the disc 3 and the mounting seat 1 more stable. This design can effectively disperse and resist the weight and force from the disc 3 and the structures above it, preventing loosening or damage of the connection caused by excessive single-point stress, thereby improving the stability and safety of the entire lifting tooling.

[0032] In a further preferred embodiment of the present utility model, a second annular groove is formed at the bottom of the box body 9, and a plurality of second connection blocks 19 are slidably installed on the inner wall of the second annular groove. The bottoms of the plurality of second connection blocks 19 are all fixedly connected to the top of the support plate 11.

[0033] In this embodiment, the sliding connection mode between the second annular groove and the second connection blocks 19 provides additional stability for the connection between the box body 9 and the support plate 11. This design enables the support plate 11 to more evenly distribute the weight and force from the structures below to the bottom of the box body 9 when bearing the weight and force from the structures below, thereby enhancing the structural strength of the entire lifting mechanism.

[0034] In a further preferred embodiment of the present utility model, a protective housing 20 is fixedly installed on one side of the top plate 5. The protective housing 20 is located outside the second motor 7, and one side inner wall of the protective housing 20 is fixedly connected to one side of the second motor 7.

[0035] In this embodiment, by using the protective housing 20, a relatively enclosed operating environment can be provided for the second motor 7, effectively isolating the second motor 7 from external environmental factors such as dust, moisture, and corrosive gases. This helps to extend the service life of the second motor 7 and reduce failures and maintenance costs caused by environmental factors.

[0036] In a further preferred embodiment of the present utility model, the screw rod 6 is made of stainless steel, and the thickness of the top plate 5 is not less than 20 cm.

[0037] In this embodiment, the screw rod 6 made of stainless steel has excellent corrosion resistance and can resist the erosion of various chemical substances, including water, air, acids, alkalis, etc. By setting the thickness of the top plate 5 to not less than 20 cm, the structural strength of the top plate 5 can be significantly enhanced, enabling it to withstand greater weight and force, ensuring the safety and reliability during the lifting process.

[0038] In summary, compared with the related art, in this solution, through the combined use of the first motor 2 and the hydraulic cylinder 4, it is convenient to adjust the height and angle of the top plate 5, enabling the lifting mechanism to move the clamped structural steel beam to the approximate position where it needs to be installed. By using the lifting mechanism, not only can the structural steel beam be clamped, but also the horizontal position, installation height, and installation angle of the structural steel beam can be adjusted. The adjustment is relatively convenient and does not rely on manual operation by workers. This can reduce the labor intensity of workers and improve the installation accuracy of the structural steel beam. By using the telescopic rod 16, the stability of the entire lifting mechanism in the vertical direction can be further enhanced. During the lifting process, even when affected by wind or other external factors, the telescopic rod 16 can provide additional support force to prevent the horizontal plate 14 and the clamping member 15 from shaking, thus ensuring the safe lifting of the structural steel beam.
