Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of safety hooks, in particular to a lightweight anti-drop safety hook. Background Art
[0002] Working at heights is a common but dangerous task in the maintenance and construction of power transmission line towers. This work may involve inspections, inspections, maintenance, installation of equipment or repairs. Falling from heights is a major cause of personal injury and death in production safety accidents, in addition to electric shock. Currently, tower climbing operations mostly use self-locking devices or double-hook safety belts to alternately climb. However, when the self-locking device is installed for the first time, the operator needs to climb to the top of the tower to hang the guide rope, and the last operator must also remove the guide rope after use, that is, the first and last operations cannot provide convenient protection for the operators; and when using double-hook safety belts to alternately climb, the safety hook needs to be removed and buckled once for each step in the process of moving up and down, and the climbing speed is slow, especially in some special types such as steel pipe towers. Operators frequently turn back to remove the safety hooks, which will cause great psychological pressure. Utility Model Content

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0026] The utility model embodiment discloses a lightweight anti-drop safety hook.
[0027] Reference Figure 1 The hook 13 is an aluminum alloy hook, which makes the hook lighter, and the surface of the hook 13 is coated with an anti-skid coating to improve the anti-skid performance of the hook 13. The front side of the fixing ring 6 is hinged with a baffle 7, and a reset spring 11 is installed at the connection between the fixing ring 6 and the baffle 7 to facilitate the reset of the baffle 7. The bent part of the hook 13 is provided with an automatic locking device 1, and a spring locking component 2 is provided at one end of the hook 13 close to the fixing ring 6. A support rod 8 is provided between the automatic locking device 1 and the spring locking component 2. A buffer bag 4 is suspended on the lower side of the fixing ring 6, and a rubber bag 3 is provided on the outside of one end of the fixing ring 6, the hook 13 and the baffle 7. The outer wall of the end of the hook 13 close to the fixing ring 6 is fixed with an attached hand hook 5, which can be installed and disassembled, and the hand hanging accessories on both sides are installed to ensure the stability during climbing to the greatest extent.
[0028] Reference Figure 1 A first anti-slip strip 9 is provided on the inner side of the hook 13 and at the end away from the fixing ring 6, a second anti-slip strip 10 is provided on the inner side of the hook 13 and between the automatic locking device 1 and the spring locking component 2, and a third anti-slip strip 12 is provided on the inner side of the hook 13 and at the end close to the fixing ring 6. The first anti-slip strip 9, the second anti-slip strip 10 and the third anti-slip strip 12 are all threadedly locked with the hook 13 by bolts, which is convenient for disassembly and replacement. The first anti-slip strip 9, the second anti-slip strip 10 and the third anti-slip strip 12 are all wear-resistant rubber strips, which improve the wear resistance of the first anti-slip strip 9, the second anti-slip strip 10 and the third anti-slip strip 12.
[0029] In the utility model, when in use, since the hook 13 is made of lightweight and high-strength aluminum alloy material, it has an excellent strength-to-weight ratio and can meet the needs of the safety hook in various working environments. Since the surface of the hook 13 is made of anti-slip material, it can ensure that the hook remains stable when in contact with the support and reduce the risk of accidental sliding or movement. Due to the arrangement of the first anti-slip strip 9, the second anti-slip strip 10 and the third anti-slip strip 12 inside the hook 13, the friction force is increased to ensure that no lateral sliding occurs during use. Since the upper part of the hook 13 is provided with an automatic locking device 1, the locking function can be automatically realized when subjected to tension or load. Since the middle and lower parts of the hook 13 are provided with a spring locking component 2 and a buffer bag 4, the spring locking 2 components can realize the fixed locking function above the climbing safety hook and the movable unlocking function below the climbing safety hook. Since the side of the hook 13 is provided with an attached hand hook 5, it can be installed and disassembled, and the hand hanging accessories on both sides can be installed to ensure the stability during climbing to the greatest extent.
[0030] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
