[0032] like Figure 1-3As shown, the present invention is an automatic rope breaking holding system for a stacker loading platform in a logistics warehouse, comprising a lifting pulley mechanism 2 of a loading platform 1, a spring mechanism 3 being installed at the lower end of the lifting pulley mechanism 2, the spring mechanism 3 being connected to a wedge-shaped iron clamping mechanism 5 through an anti-fall guide wheel mechanism 4, and the wedge-shaped iron clamping mechanism 5 being arranged on a T-shaped guide rail 39 of the loading platform 1.

[0033] like Figure 4 , 5 As shown, the lifting and lowering pulley mechanism 2 includes a wire rope pulley 8 and a wire rope 7. The wire rope 7 hangs the wire rope pulley 8. The axial center hole of the wire rope pulley 8 is installed with a bearing 9. The bearing 9 is installed with a spindle 10. The end of the spindle 10 is connected with an extension shaft 11 by bolts. The extension shaft 11 is installed in the long hole of the rib plate of the cargo platform 1. The long hole is used for the up and down sliding of the spindle 10. The extension shaft 11 is installed with two bolt-connected clamps 12. The two clamps 12 are clamped on both sides of the rib plate of the cargo platform 1 to prevent the lifting and lowering pulley mechanism 2 from swinging. A support frame 13 is installed on the spindle 10. The lower part of the support frame 13 is provided with a screw rod 14. The screw rod 14 is connected to the spring mechanism 3 through a nut.

[0034] like Figure 6 , 7 As shown, the spring mechanism 3 includes a spring 15 and a sleeve 16. The spring 15 is arranged in the sleeve 16. Two groups of guide shafts 17 are symmetrically installed in the guide holes on the sleeve 16. The guide shafts 17 are connected to the ribs of the cargo platform 1 through guide shaft fixing seats and bolts. The sleeve 16 slides up and down along the guide shaft 17 through the expansion and contraction of the spring 15. The sleeve 16 is connected to the anti-fall chain connecting plate 18 through bolts, and the anti-fall chain connecting plate 18 is connected to the anti-fall guide wheel mechanism 4.

[0035] like Figure 8-11 As shown, the anti-falling guide wheel mechanism 4 includes two groups of redirecting wheels 22, and the two redirecting wheels 22 are fixed on the same anti-falling spindle 23 through anti-falling bearings 19 and spacers respectively. The two ends of the anti-falling spindle 23 are fixed on the anti-falling spindle support 24, and the anti-falling spindle support 24 is connected to the vertical plate of the cargo platform 1 by bolts. Chains 21 are suspended on the redirecting wheels 22, and one end of the chain 21 is connected to the anti-falling chain connecting plate 18 of the spring mechanism 3 through a nut chain connecting rod 20, and the other end is connected to the wedge iron clamping mechanism 5 through an axial connecting plate 25 with a hole.

[0036] like Figure 12-14As shown, the wedge-shaped iron clamping mechanism 5 includes a fixed seat 32, and the fixed seat 32 is arranged on the T-shaped guide rail 39 of the cargo platform 1. A wedge-shaped clamping wheel group 27 and a wedge-shaped clamping block group 35 are respectively arranged on both sides of the T-shaped guide rail 39. The wedge-shaped clamping wheel group 27 and the wedge-shaped clamping block group 35 are respectively connected to the anti-falling guide wheel mechanism 4 through an anti-falling pull rod 1 26 and an anti-falling pull rod 2 34. The upper end of the anti-falling pull rod 1 26 is connected to the axial connecting plate 25 of the anti-falling guide wheel mechanism 4 by bolts, and the lower end of the anti-falling pull rod 26 is connected to the wedge-shaped clamping wheel group 27 by threads. The clamping wheel group 27 includes two rollers 28 with different diameters, a roller 29 and a wedge-shaped frame 30. The side of the wedge-shaped frame 30 is provided with a folded guide plate 31. The wedge-shaped clamping wheel group 27 is installed in a fixed seat 32 with a wedge angle formed inside. A side baffle 1 33 is installed on the wedge-shaped clamping wheel group 27. The side baffle 1 33 is fixed to the fixed seat 32 by a countersunk screw. The side baffle 1 33 has an inclined guide groove corresponding to the wedge-shaped clamping wheel group 27. The wedge-shaped clamping wheel group 27 moves upward and moves toward the center of the fixed seat 32. The anti-fall pull rod The upper end of the second anti-falling pull rod 34 is connected to the shaft connecting plate 25 of the anti-falling guide wheel mechanism 4 by bolts, and the lower end of the anti-falling pull rod 34 is connected to the wedge-shaped clamping block group 35 by threads. The wedge-shaped clamping block group 35 includes a wedge-shaped iron 36 and two guide pins 37. The upper part of the wedge-shaped iron 36 has an opening threaded hole, and the side surface is provided with an anti-skid pattern for increasing friction resistance. The side surface of the wedge-shaped iron 36 is provided with two guide pins 37. The wedge-shaped clamping block group 35 is installed in a fixed seat 32 with a wedge angle formed inside. A side baffle plate 2 38 is installed on the wedge-shaped clamping block group 35. The side baffle plate 2 38 is connected to the wedge-shaped iron 36 by screw thread. The side baffle 38 is fixed to the fixing seat 32 through the countersunk screws, and an inclined guide groove corresponding to the wedge-shaped clamping block group 35 is opened. The wedge-shaped clamping block group 35 moves upward and moves toward the center of the fixing seat 32 at the same time. The wedge-shaped clamping wheel group 27 and the wedge-shaped clamping block group 35 move upward at the same time and instantly move toward the center of the wedge-shaped fixing seat 32 at the same time, and are clamped on the T-shaped guide rail 39 located at the center position of the fixing seat 32. Through the lateral force generated by the angle formed by the wedges on both sides, the wedge-shaped clamping wheel group 27 and the wedge-shaped clamping block group 35 are firmly clamped on the T-shaped guide rail 39 through friction.

[0037] like Fig.15 , 16As shown, the spring mechanism 3 is connected to a detection alarm mechanism 6, and the detection alarm mechanism 6 includes a detection piece 42. The detection piece is connected to the lower part of the sleeve 16 of the spring mechanism 3 by bolts. A proximity switch is correspondingly arranged at the detection piece. The proximity switch 40 is installed on the detection bracket 41 by nuts. The detection bracket 41 is installed on the side of the cargo platform 1 by bolts. When the rope breaks, the spring 15 immediately extends. When the proximity switch 40 detects that the detection piece 42 in the normal use position changes, a signal is immediately sent out. The system immediately performs an audible and visual alarm according to the judgment, and the system is powered off for protection.

[0038] During normal use, the spring 15 is in a compressed state. After the wire rope 7 breaks, the compressed spring 15 naturally stretches by internal force, and drives the wedge-shaped iron clamping mechanism 5 through the anti-fall guide wheel mechanism 4. The wedge-shaped iron clamping mechanism 5 is used to instantly hold the T-shaped guide rail 39 through the wedge-shaped clamping wheel group 27 and the wedge-shaped clamping block group 35, so that the cargo platform 1 stops instantly. At the same time, the detection alarm mechanism 6 sends out an alarm signal after detecting the fall of the detection piece 42, and the system is powered off for protection.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
