[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model. It should be noted that, without conflict, the embodiments and features in the present application can be arbitrarily combined with each other.

[0019] Please refer toFigures 1 to 4 A hoisting structure of a lifting machine is provided on the lifting machine for hoisting materials, including a fixing part 10 and a supporting member 20. The fixing part 10 is located above the supporting member 20 and is connected to the lifting machine. The hoisted material is placed on the supporting member 20. A telescopic member 30 is provided on the fixing part 10, and the piston end of the telescopic member 30 faces the supporting member 20. When the telescopic member 30 extends, its piston end can abut against the hoisted material to limit the uniqueness of the hoisted material and keep the hoisted material stable during the hoisting and moving process.

[0020] Please refer to Figures 1 to 4 , the fixing part 10 is in a cubic shape, and an installation plate 11 is provided on its top. The installation plate 11 is a flat plate, and a fixing plate is provided in the middle of the installation plate 11. Around the fixing part 10, a number of fixing holes 111 are provided on the installation plate 11 for connecting the lifting machine; a cavity is provided in the middle of the fixing part 10 to reduce the overall weight of the fixing part 10.

[0021] Reinforcing ribs 12 are provided at the connection between the fixing part 10 and the installation plate 11. Two reinforcing ribs 12 are in a group and are symmetrically arranged with respect to the fixing part 10. Preferably, a number of groups of reinforcing ribs 12 are arranged at intervals along the connection between the fixing part 10 and the installation plate 11 to improve the connection strength between the fixing part 10 and the installation plate 11 and avoid cracking at the connection between the fixing part 10 and the installation plate 11 when hoisting materials. The longitudinal section of the reinforcing rib 12 is similar to a right triangle, and its two perpendicular surfaces are respectively connected to the bottom surface of the installation plate 11 and the side surface of the fixing part 10.

[0022] The supporting member 20 is provided below the fixing part 10 through a connecting member 21, and the hoisted material is placed on the supporting member 20. During hoisting, the main forces on the supporting member 20 and the fixing part 10 are perpendicular to the ground. To improve the connection strength between the supporting member 20 and the fixing member, the connecting member 21 is in the shape of a strut, and its two ends are respectively vertically connected to the bottom of the fixing part 10 and the top of the supporting member 20, so that the force on the connecting member 21 is along its length direction and reduces its tangential force.

[0023] A stop member 22 is further provided on the top of the supporting member 20. The stop member 22 is spaced from the connecting member 21, and the stop member 22 is close to the end of the supporting member 20. The stop member 22 protrudes from the top surface of the supporting member 20, and the height of the stop member 22 is less than the height of the connecting member 21, so as to form a notch above the supporting member 20. The hoisted material can move from above the stop member 22 to the middle of the supporting member 20. The stop member 22 and the connecting member 21 can form stops at both ends of the supporting member 20 to limit the displacement of the hoisted material on the supporting member 20 and prevent the hoisted material from displacing along the top surface of the supporting member 20 and detaching from the supporting member 20.

[0024] Above the supporting member 20, a telescopic member 30 is provided. The piston end of the telescopic member 30 faces the supporting member 20. When hoisting materials, the telescopic member 30 extends, and the piston end of the telescopic member 30 abuts against the hoisted materials, applying pressure to the hoisted materials, thereby restricting the displacement of the hoisted materials and preventing the hoisted materials from displacing on the supporting member 20, avoiding safety accidents caused by the shaking of the materials during hoisting.

[0025] Specifically, in this embodiment, the telescopic member 30 is a cylinder, fixed on the fixing part 10, and its piston end is arranged downward. The hoisted materials are hung on the supporting member 20, and the hoisting machinery lifts the materials. The telescopic member 30 extends, and its piston end abuts against the top of the hoisted materials, restricting the displacement of the materials in the vertical direction, thereby preventing the materials from shaking during the hoisting and moving process.

[0026] Preferably, the telescopic member 30 is arranged on the outer side wall of the fixing part 10 so that the telescopic member 30 is located beside the supporting member 20 above. When the piston end of the telescopic member 30 abuts against the top of the hoisted materials, the projection of the piston end of the telescopic member 30 on the top surface of the supporting member 20 is located outside the top surface of the supporting member 20, so that in the lateral direction, the supporting member 20 and the telescopic member 30 are respectively on both sides of the hoisted materials, and the supporting member 20 and the telescopic member 30 can also play a role in limiting the hoisted materials in the lateral direction.

[0027] Preferably, an elastic member 31 is arranged at the end of the piston end of the telescopic member 30, and the piston end of the telescopic rod contacts the materials through the elastic member 31 to avoid rigid collision between the piston end of the telescopic member 30 and the materials when the telescopic member 30 limits the materials, resulting in damage to the telescopic member 30.

[0028] Furthermore, a distance sensor is arranged at the bottom of the supporting member 20. The distance sensor is electrically connected to the control system of the hoisting machinery. The distance sensor is used to detect the height of the supporting member 20 to prevent the bottom of the materials from colliding when the hoisting machinery lowers the materials.

[0029] Taking the hoisting of the steel arch 50 as an example, in this embodiment, the hoisting machinery is a gantry crane. There are two spaced arms 40 arranged on the crane. The mounting plate 11 is fixed to the bottom of the arm 40 by bolts. The crane hoists the steel arch 50 through two hoisting structures, as Figure 4 shown.

[0030] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, not to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
