The support frame 1 is used to support the connecting plate 2 and increase the height of the connecting plate 2. On the side wall of the connecting plate 2 away from the support frame 1, a first through hole 21 is opened and a first slewing bearing 31 is fixedly connected. The first through hole 21 is used for the hoisting wire rope to pass through. The first through hole 21 is located at the center position on the rear side of the connecting plate 2. The inner wall of the first through hole 21 is communicated with the inner wall of the first slewing bearing 31. A second slewing bearing 32 is rotatably connected to the outer wall of the first slewing bearing 31. The first slewing bearing 31 and the second slewing bearing 32 are used to enable the overhead crane to rotate. The upper end of the second slewing bearing 32 is fixedly connected with a first cushion plate 4. On one side wall of the first cushion plate 4, a second through hole 41 is opened. The second through hole 41 is used for the hoisting wire rope to pass through. The second through hole 41 is located in the upper side direction of the second slewing bearing 32. The inner wall of the second through hole 41 is communicated with the inner wall of the second slewing bearing 32. On the side wall of the first cushion plate 4 away from the second slewing bearing 32, a support plate 42 is fixedly connected. On the lower surface of the connecting plate 2, a reinforcing member 22 is fixedly connected. The reinforcing member 22 is used to strengthen the connection between the connecting plate 2 and the support frame 1 and increase the bearing capacity of the connecting plate 2. The other end of the reinforcing member 22 is fixedly connected to the rear side of the support frame 1. The end of the support frame 1 away from the connecting plate 2 is fixedly connected with a mounting plate 8. On one side wall of the mounting plate 8, a plurality of mounting holes are opened. The mounting plate 8 is used to fix the support frame 1.
[0025] Secondly, as Figure 1 and Figure 4 shown, one end of the support plate 42 away from the first cushion plate 4 is fixedly connected with a second cushion plate 43. On one side wall of the second cushion plate 43, a third through hole 44 is opened. The third through hole 44 is located in the upper side direction of the second through hole 41. The inner wall of the second through hole 41 is communicated with the inner wall of the support plate 42. The third through hole 44 is used for the hoisting wire rope to pass through.
[0026] Furthermore, as Figure 1 and Figure 4 shown, on the side wall of the second cushion plate 43 away from the support plate 42, a fixing plate 5 is fixedly connected. The fixing plate 5 is located in front of the third through hole 44. On the side wall of the fixing plate 5 away from the second cushion plate 43, two overhead crane main body plates 51 are fixedly connected. Between the two overhead crane main body plates 51, two fixing shafts 6 are fixedly connected together. The two fixing shafts 6 are respectively located in the front and rear side directions of the overhead crane main body plates 51. The two fixing shafts 6 are flush. The two ends of the fixing shafts 6 respectively extend outside the side walls of the overhead crane main body plates 51 away from each other. The fixing plate 5 is used to support the overhead crane main body plates 51. The overhead crane main body plates 51 are used to support the fixing shafts 6 and the limiting rods 62. The rollers 61 are used to support the hoisting wire rope.
[0027] Still further, asFigure 1 and Figure 4 As shown in Figure 4 , a roller 61 is rotatably connected to the outer wall of the fixed shaft 6 through a bearing. On the side where the two overhead crane main plates 51 are close to each other, two limiting rods 62 are fixedly connected together. The two limiting rods 62 are located at the lower front position of the overhead crane main plates 51 and are flush with each other. The limiting rods 62 are used to guide the hoisting steel wire rope and limit its movement range.
[0028] Furthermore, as Figure 1 and Figure 5 As shown in Figure 5 , a baffle assembly 7 for limiting the first backing plate 4 is provided on the upper surface of the connecting plate 2. The baffle assembly 7 includes: a baffle 71, a connecting member 72, and a pin 73. The baffle 71 is placed on the upper surface of the connecting plate 2. The connecting member 72 is rotatably connected to both the connecting plate 2 and the baffle 71. The pin 73 is inserted into one end of the baffle 71 away from the connecting member 72, and one end of the connecting member 72 extends outside the lower surface of the connecting plate 2. One end of the first backing plate 4 away from the second through hole 41 extends to the inner wall of the baffle 71. The baffle 71 is used to limit the first backing plate 4 during transportation without rotation.
[0029] As Figures 1-5 shown in Figures 1-5 , the principle of the overhead crane and the 360° rotation mechanism of the hoisting steel wire rope provided in this embodiment is as follows: When using this mechanism, use the mounting holes on the mounting plate 8 to firmly fix this mechanism on the ground. Connect one end of the hoisting steel wire rope to the lifting mechanism. The other end of the hoisting steel wire rope passes through the first through hole 21, the first slewing bearing 31, the second slewing bearing 32, the second through hole 41, and the third through hole 44 from bottom to top, then passes over the two rollers 61, passes between the two limiting rods 62, and is connected to the cargo fixing device. Cooperating with the lifting mechanism can lift and move the cargo. By the mutual rotation of the first slewing bearing 31 and the second slewing bearing 32, the overhead crane and the hoisting steel wire rope can rotate 360°, realizing operations at more angles.
