[0001] This utility model relates to the field of safety equipment technology for power construction, and in particular to a convenient fall protection auxiliary tool for high-altitude operations in power construction. Background Technology

[0002] During power construction, high-altitude operations such as working on power poles and transmission towers are frequent. Fall protection tools are core equipment to ensure the safety of workers. Most existing fall protection tools are connected to the work platform through ropes and buckles.

[0003] The existing technology has the following problems: Traditional tools' hinges, bolts, and other connecting parts are prone to loosening due to vibration and wear, and lack effective anti-loosening structures. Once the bolts fall off, the anti-fall function may fail, leading to safety accidents. Utility Model Content

[0004] The main purpose of this utility model is to provide a convenient fall protection auxiliary tool for high-altitude operations in power construction, which can effectively solve the problem of high risk of loose connections.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A convenient fall protection auxiliary tool for high-altitude operations in power construction includes a first hinge, a second hinge that is rotatably connected inside the first hinge, a bolt that is threaded inside the first hinge, a wire loop that is provided on the outside of the second hinge, an anti-loosening mechanism that is provided on the outside of the second hinge, and a warning mechanism that is provided on the outside of the first hinge. The anti-loosening mechanism includes a housing, the outer side of which is fixedly connected to the outer side of the second hinge. A slider is slidably connected inside the housing. Two limiting blocks are fixedly connected to the outer side of the slider. A connecting rod is fixedly connected to the outer side of the slider, and a spring is sleeved around the outer periphery of the connecting rod. A pull block (55) is fixedly connected to one end of the connecting rod (53). The indicator mechanism includes a housing, with the outer side of the housing fixedly connected to the outer side of a hinge. A micro motor is housed inside the housing, and a protrusion is fixedly connected to the output end of the micro motor. A mounting plate is fixedly connected inside the housing, and a mounting rod is slidably connected inside the mounting plate. A counterweight is fixedly connected to one end of the mounting rod, and an electrode plate is fixedly connected to the other end of the mounting rod. An indicator light is fixedly connected inside the housing, and an electrode plate is located at the bottom of the indicator light. A controller and an infrared sensor are also housed inside the housing. A battery is also housed inside the housing. In the free state of the spring, the limiting block engages inside the bolt to prevent the bolt from reversing.

[0006] Preferably, the outer circumferential thread of the bolt is connected to the inside of the second hinge; Preferably, the controller is equipped with a delay filtering module. When the infrared sensor continuously detects that the distance between hinge 1 and hinge 2 is greater than a preset threshold and lasts for ≥1s, the controller starts the micro motor to drive the protrusion to rotate at least one revolution. The protrusion pushes the counterweight to close electrode 1 (66) and electrode 2, and the indicator light flashes to alarm.

[0007] Preferably, the outer side of the connecting rod is slidably connected to the inside of the housing.

[0008] Preferably, the limiting block is slidably connected to the inside of the outer shell, and the limiting block is engaged inside the bolt.

[0009] Preferably, one end of the spring is fixedly connected to the inside of the outer casing, and the other end of the spring is fixedly connected to the outside of the slider.

[0010] Preferably, the protrusion maintains sliding contact with the counterweight during rotation and pushes the counterweight to move in the direction of the second electrode plate.

[0011] Preferably, the first electrode sheet is bonded and connected to the second electrode sheet under the pushing force of the protrusion.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This utility model provides a convenient fall protection auxiliary tool for high-altitude operations in power construction. The anti-loosening mechanism uses a spring to push the limit block into the bolt, preventing the bolt from rotating and loosening. Combined with the threaded connection between the bolt and the hinge, it forms a double anti-loosening structure. Disassembly can be achieved simply by pulling the pull block, making it easy to operate. This utility model provides a convenient fall protection auxiliary tool for high-altitude operations in power construction. The indicator mechanism detects the distance between two hinges through an infrared sensor. When the distance is too far, the controller starts a micro motor to drive the protrusion to rotate. The protrusion pushes the counterweight, which drives the mounting rod and electrode plate one. Electrode plate one and electrode plate two come into contact, and the indicator light is activated to prompt the staff to adjust the distance between hinge one and hinge two.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] like Figure 1-5 As shown, a convenient fall protection auxiliary tool for high-altitude operations in power construction includes a first hinge 1, a second hinge 2 rotatably connected inside the first hinge 1, a bolt 3 threadedly connected inside the first hinge 1, a wire ring 4 on the outside of the second hinge 2, an anti-loosening mechanism 5 on the outside of the second hinge 2, and a warning mechanism 6 on the outside of the first hinge 1. The anti-loosening mechanism 5 includes a housing 50. The outer side of the housing 50 is fixedly connected to the outer side of the hinge 2. A slider 51 is slidably connected inside the housing 50. Two limit blocks 52 are fixedly connected to the outer side of the slider 51. A connecting rod 53 is fixedly connected to the outer side of the slider 51. A spring 54 is sleeved on the outer periphery of the connecting rod 53. A pull block 55 is fixedly connected to one end of the connecting rod 53. It should be noted that after hinge 1 and hinge 2 are closed, a safety rope is wrapped around them. Tightening bolt 3 achieves initial fixation. Spring 54 pushes slider 51 to drive limit block 52 into the groove of bolt 3 to prevent bolt 3 from rotating and loosening. When disassembling, pull block 55, connecting rod 53 drives slider 51 to compress spring 54, limit block 52 disengages from bolt 3, and bolt 3 can be loosened to open hinge 1 and hinge 2.

[0017] The prompting mechanism 6 includes a housing 60, which is fixedly connected to the outside of hinge 1. A micro motor 61 is installed inside the housing 60, and a protrusion 62 is fixedly connected to the output end of the micro motor 61. A mounting plate 63 is fixedly connected inside the housing 60, and a mounting rod 64 is slidably connected inside the mounting plate 63. A counterweight 65 is fixedly connected to one end of the mounting rod 64, and an electrode plate 66 is fixedly connected to the other end of the mounting rod 64. An indicator light 67 is fixedly connected inside the housing 60, and an electrode plate 68 is installed at the bottom of the indicator light 67. A controller 69 is installed inside the housing 60, an infrared sensor 610 is installed inside the housing 60, and a battery 611 is installed inside the housing 60. When the spring 54 is in a free state, the limiting block 52 is engaged inside the bolt 3 to prevent the bolt 3 from reversing. Battery 611 supplies power to all electrical components. Infrared sensor 610 detects the distance between hinge 1 and hinge 2 in real time. When the distance between hinge 1 and hinge 2 becomes too loose, controller 69 starts micro motor 61. Micro motor 61 drives protrusion 62 to rotate. Protrusion 62 pushes counterweight 65 to slide mounting rod 64. Electrode 1 66 contacts electrode 2 68. Indicator light 67 emits red light alarm to prompt the operator to adjust the distance between hinge 1 and hinge 2.

[0018] It should be noted that a delay filtering module is provided in the controller 69. When the infrared sensor 610 continuously detects that the distance between hinge 1 and hinge 2 is greater than the preset threshold and lasts for ≥1s, the controller 69 starts the micro motor 61 to drive the protrusion 62 to rotate at least one revolution. The protrusion 62 pushes the counterweight 65 to close electrode 1 66 and electrode 2 68, and the indicator light 67 flashes to sound an alarm.

[0019] like Figure 2 , Figure 3 As shown, the outer thread of bolt 3 is connected to the inside of hinge 2.

[0020] It should be noted that bolt 3 ensures the connection strength between hinge 1 and hinge 2, and pull block 55 facilitates quick operation during high-altitude work.

[0021] like Figure 4 As shown, the outer side of the connecting rod 53 is slidably connected to the inside of the housing 50.

[0022] It should be noted that the outer casing 50 provides a sliding guide for the connecting rod 53, ensuring that the limiting block 52 is accurately engaged in the groove of the bolt 3 and avoiding displacement.

[0023] like Figure 3 , Figure 4 As shown, the outer side of the limiting block 52 is slidably connected to the inside of the outer shell 50, and the limiting block 52 is snapped into the inside of the bolt 3.

[0024] It should be noted that the fit between the limiting block 52 and the groove of the bolt 3 effectively prevents the bolt 3 from loosening.

[0025] like Figure 4 As shown, one end of the spring 54 is fixedly connected to the inside of the housing 50, and the other end of the spring 54 is fixedly connected to the outside of the slider 51.

[0026] It should be noted that the spring 54 ensures that the limit block 52 is tightly engaged with the bolt 3, and at the same time assists the limit block 52 in resetting.

[0027] like Figure 5 As shown, when the protrusion 62 rotates, it maintains sliding contact with the counterweight 65 and pushes the counterweight 65 to move towards the electrode plate 68.

[0028] It should be noted that the cam structure of the protrusion 62 can periodically push the counterweight 65, causing the electrode plate 66 and the electrode plate 68 to intermittently contact each other, thereby realizing the flashing indication function of the indicator light 67.

[0029] like Figure 5 As shown, electrode plate 66 is in contact with electrode plate 68 under the pushing force of protrusion 62, thus establishing electrical connection. It should be noted that electrode 66 and electrode 68 are made of copper, which has good conductivity. When they come into contact, they can trigger the status change of indicator light 67, providing intuitive feedback on the tool's connection status.

[0030] Working principle: Open hinge 1 and hinge 2. Hinge 2 has a ratchet inside, which can lock itself. Wrap it around the safety rope and tighten bolt 3 to make hinge 1, hinge 2 and the safety rope fit tightly. Spring 54 pushes limit block 52 into bolt 3 to complete the anti-loosening fixation and realize the anti-fall connection. During operation, infrared sensor 610 detects the distance between hinge 1 and hinge 2 in real time. When the distance between hinge 1 and hinge 2 is too loose, controller 69 starts micro motor 61. The micro motor 61 drives the protrusion 62 to rotate, and the protrusion 62 pushes the counterweight 65 to make the mounting rod 64 slide. Electrode plate 1 66 and electrode plate 2 68 come into contact, and the indicator light 67 emits a red light alarm to prompt the operator to adjust the distance between hinge 1 and hinge 2. After the operation is completed, pull the pull block 55 to disengage the limit block 52 from the bolt 3, and rotate the bolt 3 in the opposite direction to loosen hinge 1 and hinge 2. The tool can then be removed. Regularly check the battery 611 power and the wear of each component to ensure stable tool performance.
