The locking hook disengages from the right angle side of the angle iron, completing the unlocking and disassembly.
[0016] The process of fixing and disassembling the device on the angle iron is simple and convenient for power workers to suspend suspended objects during high-altitude operations. Attached Figure Description

[0024] This invention provides a suspension device for angle iron, which solves the technical problem in the prior art where ropes are fixed to angle iron to suspend objects, but fixing and disassembling the ropes is cumbersome and inconvenient.
[0025] Please see Figure 1-3 An embodiment of the present invention provides a suspension device for angle iron, comprising: a support base 1, a slider 2, a traction rope 3, and a locking hook 4; A hanging object 5 is fixedly connected to the support base 1; The support base 1 has a through first mounting groove 6; The slider 2 has a groove 21, and a limit pin 22 is slidably connected in the groove 21; the slider 2 passes through the first mounting groove 6, and the limit pin 22 is fixed on the side wall of the first mounting groove 6. The top of the slider 2 is fixed with a first pulley 9, one end of the traction rope 3 is fixed to the support base 1, the other end of the traction rope 3 is connected to the locking hook 4, and the rope between the two ends of the traction rope 3 is placed above the first pulley 9.
[0026] It should be noted that the object is suspended on the hanging part 5, and the hanging part 5 is fixedly connected to the support base 1; First, raise the support base 1 so that the support base 1 and the slider 2 are suspended above the angle iron 13. At this time, the limiting pin 22 abuts against the top wall of the slide groove 21, the slider 2 is in the lowest position, and the hook groove 41 of the locking hook 4 is aligned with the right angle side of the angle iron 13. Figure 1 ); Next, the slider 2 is placed on the top surface of the angle iron 13. The angle iron 13 will push the slider 2 upward along the support base 1. The limiting pin 22 moves away from the top wall of the slide groove 21. The first pulley 9 at the top of the slider 2 also gradually moves away from the support base 1. As a result, the traction rope 3 on the first pulley 9 is pulled. The length of the rope 3 between the end of the traction rope 3 fixed to the support base 1 and the first pulley 9 increases, while the length of the rope between the end of the traction rope 3 connected to the locking hook 4 and the first pulley 9 decreases. As a result, the locking hook 4 is lifted and gradually approaches the right angle side of the angle iron 13 until the hook groove 41 of the locking hook 4 is locked outside the right angle side, completing the locking and fixing. Figure 2 ); When unlocking the device, the support base 1 is raised, and the limiting pin 22 moves towards the top wall of the slide 21 until it abuts against the top wall of the slide 21. The slider 2 disengages from the angle iron 13 and moves down along the support base 1. The first pulley 9 at the top of the slider 2 gradually approaches the support base 1, thereby shortening the length of the traction rope 3 between one end fixed to the support base 1 and the first pulley 9, and lengthening the length of the traction rope 3 between one end connected to the locking hook 4 and the first pulley 9. The locking hook 4 disengages from the right angle side of the angle iron 13, completing the unlocking and disassembly. Figure 1 ).
[0027] The process of fixing and disassembling the device on angle iron 13 is simple and convenient for power workers to suspend suspended objects during high-altitude operations.
[0028] Please see Figure 1-3 In a more specific embodiment, it further includes: a second pulley 10; The support base 1 has a through second mounting groove 7, which is close to the edge of the support base 1; The second pulley 10 is installed in the second mounting groove 7; The end of the traction rope 3 connected to the locking hook 4 and the rope between the first pulley 9 rests above the second pulley 10.
[0029] It should be noted that by placing one end of the traction rope 3 connected to the locking hook 4 and the rope between the first pulley 9 and the second pulley 10, the locking hook 4 can be pulled more smoothly to lock and unlock. The second pulley 10 is installed in the second mounting groove 7 near the edge of the support base 1. Placing the rope on the second pulley 10 can prevent the rope from contacting the edge of the support base 1 and avoid scratching the rope.
[0030] Please see Figures 1-3 In a more specific embodiment, the traction rope 3 is fixed at the fixed point 31 of the support base 1, and the center of the first pulley 9 and the center of the second pulley 10 are in the same vertical plane.
[0031] It should be noted that the traction rope 3 is fixed at the fixed point 31 of the support base 1, the center of the first pulley 9 and the center of the second pulley 10 are in the same vertical plane, so that the sliding of the rope on the first pulley 9 and the second pulley 10 can be adjusted more effortlessly.
[0032] Please see Figure 1-3 7. In a more specific embodiment, there are multiple first mounting slots 6 and sliders 2, with the multiple sliders 2 passing through different first mounting slots 6 respectively; The support base 1 has a through third mounting groove 8 between two adjacent first mounting grooves 6, and a third pulley 11 is installed in the third mounting groove 8; The traction rope 3 is placed between two adjacent first pulleys 9 and then passes under the third pulley 11.
[0033] It should be noted that multiple sliders 2 are provided that pass through the first mounting slot 6, and a third mounting slot 8 for mounting the third pulley 11 is provided between two adjacent first mounting slots 6. The traction rope 3 is placed between two adjacent first pulleys 9 and then passes under the third pulley 11. That is, the traction rope 3 first goes around the top of the first pulley 9, then around the bottom of the third pulley 11, and then around the top of another first pulley 9, so as to provide a more stable pulling force to the traction rope 3 of the traction lock hook 4.
[0034] Please see Figures 1-3 In a more specific embodiment, the centers of the plurality of first pulleys 9, the center of the third pulley 11, and the traction rope 3 are fixed at the fixed point 31 of the support base 1 in the same vertical plane.
[0035] It should be noted that the centers of the multiple first pulleys 9, the center of the third pulley 11, and the fixing point 31 of the traction rope 3 on the support base 1 are all in the same vertical plane, which makes it easier to adjust the sliding of the rope on the first pulleys 9 and the third pulley 11.
[0036] In another, more specific embodiment, the centers of the plurality of first pulleys 9, the center of the third pulley 11, the center of the second pulley 10, and the fixing point 31 of the traction rope 3 on the support base 1 are in the same vertical plane, thereby enabling more effortless adjustment of the sliding of the rope on the first pulleys 9, the second pulley 10, and the third pulley 11.
[0037] Please see Figure 1 In a more specific embodiment, the locking hook 4 is U-shaped, the traction rope 3 is connected to one end of the locking hook 4, and the end of the locking hook 4 away from the traction rope 3 is bent outward.
[0038] It should be noted that the locking hook 4 is U-shaped, the traction rope 3 is connected to one end of the locking hook 4, and the end of the locking hook 4 away from the traction rope 3 is bent outward, thus widening the opening of the locking hook 4, making it easier for the right-angled side of the angle iron 13 to be inserted into the hook groove 41 of the locking hook 4.
[0039] Please see Figure 4-5 In a more specific embodiment, the support base 1 has a through mounting hole 12; The hanging component 5 includes a vertical rod 51, which passes through the mounting hole 12; A lifting ring 52 is connected to the top of the vertical rod 51, and a hanging ring 53 is connected to the bottom of the vertical rod 51.
[0040] It should be noted that the hook on the insulating rod 14 is passed through the lifting ring 52 of the hanging object 5 and lifted. The lifting ring 52 is connected to the vertical rod 51. The vertical rod 51 passes through the mounting hole 12 on the support base 1 and is fixedly connected to the support base 1, so that the support base 1 can be lifted. The bottom end of the vertical rod 51 is connected to the hanging ring 53, so that the object can be suspended on the hanging ring 53 and the object can be lifted together.
[0041] Please see Figure 6 In a more specific embodiment, grooves 21 are provided on both opposite sides of the slider 2.
[0042] It should be noted that the slider 2 has grooves 21 on both sides, and limit pins 22 are slidably connected in the grooves 21 on both sides. The limit pins 22 on both sides are fixed on the opposite sides of the first mounting groove 6, so that the slider 2 can move up and down along the support base 1 more stably.
[0043] Please see Figure 1 In a more specific embodiment, one end of the traction rope 3 is fixed to the support base 1, specifically: One end of the traction rope 3 is fixed to the support base 1 by a fixing rivet 15.
[0044] It should be noted that one end of the traction rope 3 is fixed to the support base 1 by the fixing rivet 15. When the fixing rivet 15 is removed, the traction rope 3 can be removed from the support base 1. When the traction rope 3 needs to be fixed to the support base 1, the fixing rivet 15 is pressed down and inserted into the support base 1 for fixing.
[0045] Please see Figure 1 In a more specific embodiment, the bottom of the slider 2 is provided with an adhesive element (not shown in the figure).
[0046] It should be noted that, in order to prevent the slider 2 from shifting when placed on the top surface of the angle iron 13, an adhesive component is provided at the bottom of the slider 2, which can stabilize the position of the slider 2 on the top surface of the angle iron 13.
[0047] The viscosity of the adhesive component should be moderate to ensure that the slider 2 can detach from the top surface of the angle iron 13 when the support base 1 and the slider 2 are lifted.
[0048] The device of the present invention requires only a single lifting and lowering action to lock and unlock the angle iron, which is suitable for remote operation with auxiliary tools; when the slider is lifted, it can move to the lowest position along the support base due to its own weight, without the need for elastic components, and the structure is simple; the device of the present invention has low requirements for manufacturing process, does not require metal components, and avoids the risk of electrical short circuit.
[0049] The above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
