Description

Technical Field

[0001] This utility model relates to the field of high-altitude operation safety technology, specifically a lightweight tower climbing buckle. Background Technology

[0002] In today's power grid system, whether it's the erection of transmission towers or the maintenance of power lines, workers are required to climb power towers. Climbing is inherently dangerous, and various protective tools such as double-hook safety ropes and safety rings are currently used. These protective devices are crucial for tower climbing, providing safety guarantees for workers and ensuring their safety in the event of a fall.

[0003] Currently, safety ropes are commonly used during tower climbing and maintenance. Climbing buckles are attached to one or both ends of the safety rope. When in use, the climbing buckles are fastened to the connecting beam, connecting hole, or metal rod to prevent falls. Existing climbing buckles include a hook, a grooved locking plate, and a grooved baffle. Both the grooved locking plate and the grooved baffle are hinged to the hook, and a torsion spring is installed at the hinge. When hooking the hook, pushing the grooved baffle inward will hook the hook onto the connecting beam, connecting hole, or metal rod. At the same time, the grooved baffle will reset and seal the hook opening of the column hook. The function of the grooved locking plate is to lock the grooved baffle.

[0004] However, the above-mentioned climbing buckle still has shortcomings in use: when it is necessary to remove the hook from the connection part, it is necessary to manually press the groove-shaped locking plate to unlock it, and then press the groove-shaped baffle in the hook opening to remove the hook. However, this pressing method makes it inconvenient for the operator to exert force, or rather, it is easy to slip when exerting force, resulting in low efficiency of opening the groove-shaped baffle, thus affecting the convenience and efficiency of changing the installation position of the climbing buckle.

[0005] Therefore, this utility model provides a lightweight tower climbing buckle. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a lightweight tower climbing buckle to solve the problems mentioned in the background technology. This utility model has the advantages of more effortless and convenient control of the opening and closing of the control slot baffle and locking control, which greatly improves the convenience of switching the placement position of the climbing buckle.

[0007] To achieve the above objectives, this utility model employs the following technical solution: a lightweight tower climbing hook, comprising a hook with a connecting hole at its head, a grooved locking plate hinged to the back of the straight arm section of the hook, a grooved baffle hinged to the hook near the connecting hole, a clearance notch within the straight arm section of the hook, a pull rod elastically slidably connected within the clearance notch, a connecting rod hinged to one end of the pull rod via a connecting arm, the connecting rod body rotatably connected to the clearance notch near the connecting hole, a drive shaft rotatably connected to the groove of the grooved baffle and slidably connected to the connecting rod, and a pull shaft fixedly connected to the top of the pull rod outside the clearance notch, the pull rod, under the action of elasticity, drives one side of the grooved locking plate via the connecting rod and drive shaft, with the position near the free end abutting against the inner side of the hook tail.

[0008] Furthermore, the straight arm section of the hook has waist-shaped holes on both sides that provide clearance, and the two ends of the pull shaft pass through the waist-shaped holes with a gap.

[0009] Furthermore, anti-detachment hanging plates are welded to both ends of the pull shaft.

[0010] Furthermore, a limiting plate is welded between the two side walls within the clearance notch. The limiting plate has a guide hole that is slidably connected to the pull rod. A transition block that is fixedly connected to the pull shaft is welded to the top of the pull rod. A support spring is sleeved on the pull rod between the limiting plate and the transition block.

[0011] Furthermore, a positioning shaft is fixedly connected between the two side walls within the clearance notch, near the bottom, and a limiting sleeve fitted onto the positioning shaft is connected to the rod body of the connecting rod.

[0012] Furthermore, a positioning hole is provided between the two side walls of the groove of the groove-shaped baffle, which is rotatably connected to the drive shaft, and a guide sleeve sleeved on the outside of the connecting rod is fixedly connected to the middle of the drive shaft.

[0013] Furthermore, the grooved baffle has an anti-pinch notch on the side facing the inner groove of the hook.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, by setting a pull rod and a connecting rod on the straight arm section of the hook, and then rotating and slidingly connecting the transmission shaft to the connecting rod on the grooved baffle, and finally setting a pull shaft near the grooved locking plate and fixedly connecting it to the top of the pull rod, the operator can control the opening, closing and locking of the grooved locking plate on the straight arm section. Compared with the prior art, it does not require the operator to press the handle with a large span, thus improving the convenience of switching the position of the climbing buckle.

[0016] 2. This utility model sets a clearance notch and then sets a support spring in the clearance notch to apply elastic force to the pull rod. When the pull rod is manually pulled by the pull shaft, the support spring is directly compressed by the force. When the pull shaft is released, the support spring resets and pushes the pull rod to reset. This setting makes the sliding of the pull rod smoother and more reliable. Moreover, when the hook is engaged, the pull shaft is manually pulled down to control the opening of the slotted baffle, so it has the advantage of making it easier to control the opening of the slotted baffle.

[0021] 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.

[0022] Please see Figures 1 to 3 This utility model provides a technical solution: a lightweight tower climbing buckle, including a hook 1, the head of which is provided with a connecting hole 11, which is connected to a rope. A grooved locking plate 2 is hinged to the back of the straight arm section of the hook 1. A grooved baffle 3 located at the hook opening of the hook 1 is hinged to the hook 1 near the connecting hole 11. The function of the grooved baffle 3 is to block the hook opening of the hook 1. The function of the grooved locking plate 2 is to lock the grooved baffle 3 that blocks the hook opening of the hook 1. The grooved locking plate 2 and the hook 1 are hinged together. A torsion spring is provided at the hinge. When the grooved locking plate 2 is manually pressed, the locking of the grooved baffle 3 will be released. The specific locking structure adopts a common limit locking structure of a pin and a slot. Since this part is prior art, it will not be described in detail in this application.

[0023] In this technical solution, a clearance notch 12 is provided in the straight arm section of the hook 1. A pull rod 4 is elastically slidably connected in the clearance notch 12. One end of the pull rod 4 is hinged to a connecting rod 5 via a connecting arm 8. The rod body of the connecting rod 5 is rotatably connected to the clearance notch 12 near the connecting hole 11. In a specific implementation, it is preferred that a positioning shaft 123 near the bottom is fixedly connected between the two side walls of the clearance notch 12, and a limiting sleeve 51 sleeved on the positioning shaft 123 is connected to the rod body of the connecting rod 5. A transmission shaft 6 rotatably connected to the connecting rod 5 is slidably connected in the groove of the groove-shaped baffle 3. In a specific implementation, it is preferred that a positioning hole 31 rotatably connected to the transmission shaft 6 is provided between the two side walls of the groove of the groove-shaped baffle 3, and a guide sleeve 61 sleeved on the outside of the connecting rod 5 is fixedly connected to the middle of the transmission shaft 6. When the lever 4 moves up and down, it will drive the connecting rod 5 to swing up and down through the connecting arm 8. When the connecting rod 5 swings up and down, it will drive the groove baffle 3 to swing up and down through the transmission shaft 6, thereby controlling the opening and closing of the hook 1.

[0024] Furthermore, the top of the pull rod 4 is fixedly connected to a pull shaft 41 located outside the clearance notch 12. This pull shaft 41 is a manually operated component, which is close to the slotted locking plate 2. In a specific implementation, it is preferred that the straight arm section on the hook 1 has waist-shaped holes 121 on both sides that communicate with the clearance notch 12. The two ends of the pull shaft 41 pass through the waist-shaped holes 121 respectively. Under the action of elastic force, the pull rod 4 will drive the slotted locking plate 2 to one side near the free end and abut against the inner side of the tail of the hook 1 through the connecting rod 5 and the transmission shaft 6.

[0025] Specifically, a limiting plate 122 is welded between the two side walls inside the clearance notch 12. The limiting plate 122 has a guide hole 1221 that is slidably connected to the pull rod 4. A transition block 42 that is fixedly connected to the pull shaft 41 is welded to the top of the pull rod 4. A support spring 7 is sleeved on the pull rod 4 between the limiting plate 122 and the transition block 42. The support spring 7 applies an upward elastic thrust to the pull rod 4 through the transition block 42.

[0026] In this embodiment, anti-detachment hanging plates 411 are welded to both ends of the pull shaft 41. The anti-detachment hanging plates 411 prevent the hand from slipping off when the pull shaft 41 is manually pulled.

[0027] In this embodiment, the grooved baffle 3 has an anti-pinch notch 32 on the side facing the inner groove of the hook 1. When the grooved baffle 3 rotates towards the inner groove of the hook 1, the anti-pinch notch 32 will be opposite to the finger part, thereby effectively preventing damage to the finger.

[0028] It should be noted that hook 1, grooved locking plate 2, grooved baffle 3, pull rod 4, pull shaft 41, anti-detachment hanging plate 411, and connecting rod 5 are all made of aluminum alloy. This is to make the climbing buckle lighter. This material, combined with the opening and closing control structure of the grooved baffle 3, makes the climbing buckle easier to use. Hook 1 connects to the external rope via connecting hole 11. The rope is made of Dyneema rope, which provides sufficient connection strength while being more flexible, making climbing easier and more effortless for the user.

[0029] Working principle: When it is necessary to remove hook 1, manually hold the straight arm section of hook 1. At this time, the grooved locking plate 2 is pressed and the grooved baffle 3 is unlocked. Then manually pull down the pull shaft 41, the pull rod 4 moves down, hook 1 is subjected to force, the support spring 7 is compressed, the connecting arm 8 pushes the connecting rod 5 to rotate, and then pushes the grooved baffle 3 upward through the transmission shaft 6. At this time, the grooved baffle 3 rotates inward into hook 1, the hook opening of hook 1 is opened, and then hook 1 can be removed by simply lifting it up.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
