DETAILED DESCRIPTION

[0023] In order to deepen the understanding of the utility model, the utility model will be further described in the following embodiment, and the embodiment is only used to explain the utility model, and does not constitute the limitation of the protection scope of the utility model.

[0024] According to Figure 2 , Figure 3 , Figure 4 , Figure 5 The embodiment proposes a double-beam hoisting device, which comprises a crossbeam 2, and one end beam 1 is arranged at the left and right ends of the crossbeam 2, a lifting motor 3 is fixedly arranged on the crossbeam 2, and a lifting hook 4 is connected below the lifting motor 3.

[0025] The lifting motor 3 winds the steel wire through the lifting hook 4 to hoist the weight, the end beam 1 is slidingly arranged on the track beam, and the walking mechanism on the end beam 1 drives the end beam 1 to walk on the track beam.

[0026] The end beam 1 is provided with a roller 10 on the inner side, the roller 10 is rotatably connected with the end beam 1, the end beam 1 is provided with a roller motor 9 on the outer side, the mounting end of the roller motor 9 is fixedly connected with the end beam 1, and the output end of the roller motor 9 is fixedly connected with the roller 10. The end beam 1 is slidingly arranged on the track beam, the roller motor 9 drives the roller 10 to rotate, the roller 10 travels along the track groove formed on the track beam in rotation, and the horizontal position of the hoisting device is adjusted.

[0027] The crossbeam 2 is fixedly connected with a positioning plate 5 at the left and right ends, the end beam 1 is fixedly connected with a fixed seat 6 at the upper end, the fixed seat 6 is sleeved outside the positioning plate 5 and is slidingly connected with the positioning plate 5, the left and right sides of the fixed seat 6 are provided with a triangular seat 8, and the triangular seat 8 is fixedly connected with the end beam 1 and the fixed seat 6.

[0028] The triangular seat 8 is provided with a positioning assembly for limiting the movement of the positioning plate 5, and the triangular seat 8 is rotatably connected with a triangular gland 7 for keeping the triangular seat 8 closed.

[0029] When the end beam 1 and the cross beam 2 are assembled, the positioning plates 5 fixed at the left and right ends of the cross beam 2 are inserted into the fixed seats 6, and the positioning assembly in the triangular seat 8 locks the positioning plates 5, ensuring that the end beam 1 and the cross beam 2 are connected firmly. The adjustable design facilitates the staff to adjust the distance between the two end beams 1, thereby meeting the assembly requirements of the beams at different positions and being good in flexibility.

[0030] The triangular seat 8 is fixed at the connection between the end beam 1 and the fixed seat 6, and functions as a reinforcing rib to improve the supporting strength of the fixed seat 6. When the triangular gland 7 is lowered, the triangular gland 7 cooperates with the triangular seat 8 to protect the positioning assembly, avoiding the erosion of the positioning assembly exposed for a long time.

[0031] More specifically, the triangular gland 7 is pivotally connected to the upper end of the triangular seat 8, and the triangular gland 7 and the triangular seat 8 are mutually fitted. The side of the triangular gland 7 and the triangular seat 8 is provided with a groove 14 for accommodating the positioning assembly. Before the positioning assembly is released from the limiting of the positioning plate 5, the triangular gland 7 is previously flipped open from the upper end of the triangular seat 8.

[0032] In order to enable the triangular gland 7 to be stably combined with the upper end of the triangular seat 8, in the preferred scheme, the side of the triangular gland 7 facing the triangular seat 8 is provided with a first buckle 13 fixedly connected with the triangular gland 7, and the first buckle 13 is buckled with a first buckle groove 12 provided at the upper end of the triangular seat 8. After the triangular gland 7 is combined with the upper end of the triangular seat 8, the first buckle 13 on the triangular gland 7 is buckled into the first buckle groove 12 provided at the upper end of the triangular seat 8, which ensures that the triangular gland 7 and the triangular seat 8 can provide effective protection for the positioning assembly while not affecting the opening of the triangular gland 7.

[0033] In order to prevent the triangular gland 7 from falling back on the upper end of the triangular seat 8 when it is flipped open, in the preferred scheme, the side of the triangular gland 7 away from the triangular seat 8 is provided with a second buckle 17 fixedly connected with the triangular gland 7, and the second buckle 17 is buckled with a second buckle groove 18 provided at the upper end of the fixed seat 6. After the triangular gland 7 is completely flipped open, the second buckle 17 on the triangular gland 7 is buckled into the second buckle groove 18 provided at the upper end of the fixed seat 6, and the second buckle groove 18 limits the triangular gland 7 after being flipped open through cooperation with the second buckle 17.

[0034] Regarding the positioning assembly:

[0035] The positioning assembly comprises a positioning bolt 15 provided in the groove 14, the positioning bolt 15 penetrates into the fixed seat 6 and is threadedly connected with the fixed seat 6, and a plurality of positioning holes 16 are provided at the outer side of the positioning plate 5 and are threadedly connected with the positioning bolt 15. When the distance between the two end beams 1 is adjusted, the positioning bolt 15 is rotated and rotated out of the corresponding positioning hole 16 at the outer side of the positioning plate 5.

[0036] It is worth mentioning that the positioning holes 16 are arranged on the left and right sides of the positioning plate 5, and each positioning hole 16 is uniformly arranged along the length direction of the positioning plate 5.

[0037] In the preferred scheme, the end beam 1 is provided with a flow guide groove 11 at the upper end, and the flow guide groove 11 is communicated with the groove cavity 14. In a humid environment, the accumulated water in the triangular seat 8 through the connecting gap between the triangular gland 7 and the triangular seat 8 will flow out to both ends of the end beam 1 through the flow guide groove 11, and the water vapor will not accumulate in the triangular seat 8, thereby avoiding the corrosion of the positioning assembly.

[0038] The double-beam hoisting device winds the steel wire through the lifting hook 4 to hoist the heavy object, and the end beam 1 is slidingly arranged on the track beam. The walking mechanism on the end beam 1 drives the end beam 1 to walk on the track beam. When the end beam 1 and the cross beam 2 are assembled, the positioning plate 5 fixed on the left and right ends of the cross beam 2 is inserted into the fixed seat 6, and the positioning assembly in the triangular seat 8 locks the positioning plate 5, so that the end beam 1 and the cross beam 2 are connected firmly. The adjustable design facilitates the workers to adjust the distance between the two end beams 1, so as to meet the assembly requirements of the beams at different positions, and the flexibility is good. The triangular seat 8 is fixed at the connection between the end beam 1 and the fixed seat 6, so as to improve the supporting strength of the fixed seat 6. When the triangular gland 7 falls, the triangular gland 7 cooperates with the triangular seat 8 to protect the positioning assembly, so as to avoid the corrosion of the positioning assembly exposed for a long time.
