[0032] like Figures 1-3As shown, this utility model is an automatic rope breakage protection system for a stacker crane platform in a logistics automated warehouse. It includes a lifting rope wheel mechanism 2 for the platform 1, a spring mechanism 3 installed at the lower end of the lifting rope wheel mechanism 2, and the spring mechanism 3 connected to a wedge-shaped iron clamping mechanism 5 through an anti-fall guide wheel mechanism 4. The wedge-shaped iron clamping mechanism 5 is set on the T-shaped guide rail 39 of the platform 1.

[0033] like Figure 4 , 5 As shown, the lifting rope wheel mechanism 2 includes a wire rope wheel 8 and a wire rope 7. The wire rope 7 suspends the wire rope wheel 8. A bearing 9 is installed in the shaft hole of the wire rope wheel 8. A spindle 10 is installed on the bearing 9. An extension shaft 11 is bolted to the end of the spindle 10. The extension shaft 11 is installed in the elongated hole of the rib plate of the loading platform 1. The elongated hole is used for the up and down sliding of the spindle 10. Two clamping plates 12 are bolted to the extension shaft 11. The two clamping plates 12 are clamped on both sides of the rib plate of the loading platform 1 to prevent the lifting rope wheel mechanism 2 from swinging. A support frame 13 is installed on the spindle 10. A lead screw 14 is provided at the lower part of the support frame 13. The lead screw 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 disposed inside the sleeve 16. Two sets of guide shafts 17 are symmetrically installed in the guide holes on the sleeve 16. The guide shafts 17 are connected to the stiffeners of the loading platform 1 through guide shaft fixing seats and bolts. The sleeve 16 slides up and down along the guide shafts 17 by the extension and retraction of the spring 15. The sleeve 16 is connected to a fall-prevention chain connecting plate 18 by bolts. The fall-prevention chain connecting plate 18 is connected to the fall-prevention guide wheel mechanism 4.

[0035] like Figures 8-11 As shown, the anti-fall guide wheel mechanism 4 includes two sets of redirecting wheels 22. The two redirecting wheels 22 are respectively fixed on the same anti-fall spindle 23 through anti-fall bearings 19 and spacers. The two ends of the anti-fall spindle 23 are fixed on anti-fall spindle supports 24. The anti-fall spindle supports 24 are bolted to the upright plate of the loading platform 1. Chains 21 are suspended on each redirecting wheel 22. One end of the chain 21 is connected to the anti-fall 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 clamping mechanism 5 through a shaft connecting plate 25 with holes.

[0036] like Figures 12-14As shown, the wedge-shaped clamping mechanism 5 includes a fixed base 32, which is mounted on a T-shaped guide rail 39 of the loading platform 1. Wedge-shaped clamping wheel sets 27 and wedge-shaped clamping block sets 35 are respectively arranged on both sides of the T-shaped guide rail 39. The wedge-shaped clamping wheel sets 27 and wedge-shaped clamping block sets 35 are connected to the anti-fall guide wheel mechanism 4 via anti-fall pull rod one 26 and anti-fall pull rod two 34, respectively. The upper end of the anti-fall pull rod one 26 is bolted to the shaft connecting plate 25 of the anti-fall guide wheel mechanism 4, and the lower end of the anti-fall pull rod 26 is threaded to the wedge-shaped clamping wheel set 27. The clamping wheel assembly 27 includes two rollers 28 and 29 of different diameters and a wedge-shaped frame 30. The wedge-shaped frame 30 has a folded guide plate 31 on its side. The wedge-shaped clamping wheel assembly 27 is installed in a fixed seat 32 that forms a wedge angle. A side baffle 33 is installed on the wedge-shaped clamping wheel assembly 27 and is fixed to the fixed seat 32 by countersunk screws. The side baffle 33 has a sloped guide groove corresponding to the wedge-shaped clamping wheel assembly 27. The wedge-shaped clamping wheel assembly 27 moves upwards while simultaneously moving towards the center of the fixed seat 32. The anti-fall lever... The upper end of the second anti-fall pull rod 34 is bolted to the shaft connecting plate 25 of the anti-fall guide wheel mechanism 4. The lower end of the second anti-fall pull rod 34 is threaded to the wedge clamping block assembly 35. The wedge clamping block assembly 35 includes a wedge iron 36 and two guide pins 37. The wedge iron 36 has an open threaded hole at the top and anti-slip patterns on the side to increase friction resistance. The wedge iron 36 is equipped with two guide pins 37 on the side. The wedge clamping block assembly 35 is installed in a fixed seat 32 that forms a wedge angle inside. A side baffle 38 is installed on the wedge clamping block assembly 35. The side baffle 38 is open to the ground. The countersunk screw is fixed to the fixed base 32. The side baffle 38 has a sloped guide groove corresponding to the wedge clamping block assembly 35. The wedge clamping block assembly 35 moves upward and moves towards the center of the fixed base 32 at the same time. The wedge clamping wheel assembly 27 and the wedge clamping block assembly 35 move upward and move towards the center of the wedge fixed base 32 at the same time, and are clamped on the T-shaped guide rail 39 located at the center of the fixed base 32. Through the lateral component force generated by the included angle formed by the two wedges, the wedge clamping wheel assembly 27 and the wedge clamping block assembly 35 are firmly clamped on the T-shaped guide rail 39 by friction.

[0037] like Figure 15 , 16As shown, the spring mechanism 3 is connected to a detection alarm mechanism 6. The detection alarm mechanism 6 includes a detection piece 42, which is bolted to the lower part of the sleeve 16 of the spring mechanism 3. A proximity switch is correspondingly provided at the detection piece. The proximity switch 40 is mounted on the detection bracket 41 by a nut. The detection bracket 41 is bolted to the side of the loading platform 1. When the rope breaks, the spring 15 immediately extends. When the proximity switch 40 detects a change in the detection piece 42 in the normal operating position, it immediately sends a signal. The system immediately performs an audible and visual alarm based on the judgment, and the system cuts off the power 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 extends 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, through the wedge-shaped clamping wheel group 27 and the wedge-shaped clamping block group 35, instantly grabs the T-shaped guide rail 39, so that the loading platform 1 stops instantly. At the same time, the detection alarm mechanism 6 detects the detection piece 42 falling and issues an alarm signal, and the system is powered off for protection.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
