It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figures 1-5 As shown, a sling-type lifting device includes a housing 1, which is a box with an opening on one side. A motor 2 is installed inside the housing 1 on one side, and a reducer connected to the motor 2 is installed inside the housing 1. Heat dissipation holes are provided on both sides of the bottom of the housing 1. The output shaft of the reducer and the inside of the housing 1 are both provided with inner polygonal shaft tubes 3. The openings of the two inner polygonal shaft tubes 3 are opposite to each other and kept on the same straight line. A detachable winding roller 6 is provided between one end of the two inner polygonal shaft tubes 3. A detachable safety cloth belt 25 is provided on the outer wall of the winding roller 6. The bottom end of the safety cloth belt 25 extends to the bottom of the housing 1 and is provided with a detachable hook 26.

[0026] A detachable door 4 is provided on one side of the opening of the outer casing 1. A handle is provided on one side of the door 4. Two first fixing ears 5 are fixed on one side of the door 4. A first shaft tube 7, which is fixedly connected to both sides of the take-up roller 6, is rotatably installed through the outer wall of the first fixing ears 5. Polygonal insertion slots 8 are provided on both sides of the take-up roller 6. Polygonal insertion rods 9, which cooperate with the inner polygonal shaft tube 3, are slidably installed inside the polygonal insertion slots 8. One end of the polygonal insertion rod 9 is inserted into the inner polygonal shaft tube 3. A linkage mechanism for driving the polygonal insertion rod 9 to move laterally is provided on the outer wall of the two first fixing ears 5.

[0027] According to the above structure, the inner polygonal shaft tube 3 located inside the outer casing 1 is rotatably connected to it, and the inner polygonal shaft tube 3 located on the output shaft of the reducer is fixedly connected to it; the two polygonal insert rods 9 are driven to move through the linkage mechanism, and the polygonal insert rods 9 are controlled to engage or disengage with the two inner polygonal shaft tubes 3. When one end of the polygonal insert rod 9 is inserted into the inner polygonal shaft tube 3, the motor 2 can be started. The motor 2 drives the inner polygonal shaft tube 3 to rotate through the reducer. The inner polygonal shaft tube 3 drives the polygonal insert rod 9 to rotate. The polygonal insert rod 9 drives the take-up roller 6 to rotate. The take-up roller 6 drives the safety belt 25 to wind up or unwind. When the polygonal insert rod 9 is separated from the inner polygonal shaft tube 3, it is convenient to disassemble the take-up roller 6. The inner polygonal shaft tube 3, the polygonal insert rod 9 and the polygonal insertion slot 8 can limit each other when rotating, so that the take-up roller 6 can rotate normally.

[0028] like Figures 1-3 As shown, the linkage mechanism includes a double-ended lead screw 11 that passes through the outer walls of the two first fixed ears 5. Moving blocks 12 are threaded onto both sides of the outer wall of the double-ended lead screw 11. A linkage plate 13 is fixed to one side of each moving block 12. An annular groove 10 is formed on the outer wall of the polygonal insert 9, which rotatably connects to the linkage plate 13. A rotating shaft 17 is rotatably mounted on one side of the door 4, corresponding to the middle of the double-ended lead screw 11. One end of the rotating shaft 17 is provided with a bevel gear set 18 connected to the middle of the double-ended lead screw 11. The other end of the rotating shaft 17... The end is equipped with a dial wheel, and the outer walls of the door 4 are provided with second fixed ears 14 that are rotatably connected to the two ends of the double-headed screw 11. A guide rod that is slidably connected to the moving block 12 is provided between the outer walls of the second fixed ears 14 and the first fixed ears 5. A locking block 15 is fixed on one side of the moving block 12. The outer wall of the second fixed ears 14 is provided with a through groove that is slidably connected to the locking block 15, and one end of the locking block 15 passes through the inside of the through groove. Both inner sides of the outer shell 1 are provided with protrusions, and the outer walls of the protrusions are provided with locking grooves 16 that cooperate with the locking block 15.

[0029] According to the above structure, rotating the dial wheel drives the rotating shaft 17 to rotate. The rotating shaft 17 drives the double-headed lead screw 11 to rotate through the bevel gear set 18. The double-headed lead screw 11 drives the two moving blocks 12 to move. The moving blocks 12 drive the linkage plate 13 to move. The linkage plate 13 drives the polygonal insert rod 9 to move laterally. At the same time, the moving blocks 12 drive the locking block 15 to move laterally, controlling the locking block 15 to engage or disengage from the locking slot 16, thereby facilitating the disassembly and stable fixing of the take-up roller 6.

[0030] like Figures 3-4 As shown, the outer wall of the take-up roller 6 is provided with a clamping groove, and a pressure plate 19 is fixed inside the clamp by bolts for installing and fixing the safety belt 25.

[0031] As described above, the safety belt 25 is placed into the clamping groove, and then the pressure plate 19 is fixed to the clamping groove with bolts, thereby completing the installation and fixing of the safety belt 25.

[0032] like Figure 3 As shown, a mounting plate 20 is fixed to one side of the bottom of the door 4, and a mounting groove 22 that mates with the mounting plate 20 is opened through the bottom of the outer shell 1. Two rotating rollers 21 are provided on the outer wall of the mounting plate 20 and directly below the winding roller 6.

[0033] According to the above structure, the two rotating rollers 21 are arranged so that the safety belt 25 passes between the two rotating rollers 21. When the safety belt 25 is wound up or unwound, the friction force on the safety belt 25 can be effectively reduced, thereby improving the service life of the safety belt 25.

[0034] like Figure 2 , Figure 3 and Figure 5 As shown, positioning rods 23 are provided near the four corners of the outer wall of the box door 4, and positioning guide grooves 24 that cooperate with the positioning rods 23 are provided on the outer wall of the protrusion.

[0035] Based on the above structure, the positioning rod 23 and the positioning guide groove 24 can be matched to enable the quick installation of the take-up roller 6 and further improve the stability of the take-up roller 6.

[0036] The working principle of this utility model is as follows: When replacing or repairing the safety belt 25 on the take-up roller 6, the dial wheel is rotated, which drives the rotating shaft 17 to rotate. The rotating shaft 17 drives the double-headed screw 11 to rotate through the bevel gear set 18. The double-headed screw 11 drives the two moving blocks 12 to move. The moving blocks 12 drive the linkage plate 13 to move. The linkage plate 13 drives the polygonal insert 9 to move laterally and controls the polygonal insert 9 to separate from the two inner polygonal shaft tubes 3. At the same time, the moving blocks 12 drive the locking block 15 to move laterally and controls the locking block 15 to separate from the locking groove 16. Then the take-up roller 6 can be taken out from the outer shell 1, the bolts on the pressure plate 19 can be unscrewed, the damaged safety belt 25 can be removed, and a new one can be installed. Tighten the bolts on the safety belt 25 to securely fix the pressure plate 19 in the clamping groove, thus achieving stable fixation of the safety belt 25. Then, pass the other end of the safety belt 25 through the rotating rollers 21 to complete the connection and fixation between the safety belt 25 and the take-up roller 6. Align the positioning rod 23 with the positioning guide groove 24 and insert it, align the locking block 15 with the locking groove 16, and align the polygonal rod 9 with the inner polygonal shaft tube 3. Finally, rotate the dial to insert the locking block 15 into the locking groove 16 and the polygonal rod 9 into the inner polygonal shaft tube 3, thus completing the quick installation and fixation of the safety belt 25. The structure is simple and the operation is convenient. The installation and replacement of the safety belt 25 is relatively time-saving and labor-saving, reducing labor intensity.
