Description

Technical Field

[0001] This utility model relates to the field of wire hooks, and in particular, to a wire hook. Background Technology

[0002] The wire hook is attached to the high-voltage power line using a drone. Below the wire hook is a delivery wheel with a traction rope wound around it. One end of the traction rope is attached to the tools of the worker at height. People on the ground pull the other end of the traction rope to deliver the tools to the worker at height.

[0003] Existing wire hooks only use the upper hook to hold the wire after it is hung on the wire, without a lower hook, and therefore do not fully cover the wire. In windy weather at high altitudes, the wire hooks are prone to falling or injuring people on the ground, posing a very serious safety hazard. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology, at least to a certain extent, the technical problems in the related technology, and to provide a solution to the problem of serious safety hazards existing in the wire hook.

[0005] A wire hook includes a hook body and a steel wire rope. A slider is slidably limited at the upper end of the hook body, and the slider is connected to a connecting rod with a hook. The hook body is provided with several guide pulleys and an upper hook portion for hooking the wire. A closing portion is connected to the hook body via a hinge shaft, and a torsion spring is sleeved on the hinge shaft. One end of the torsion spring abuts against the closing portion, and the other end abuts against the hook body. One end of the steel wire rope is fixed to the closing portion and wound around the guide pulleys, and the other end is fixed to the slider. The hook body is also provided with a hook-and-rebound device for closing or opening the upper hook portion.

[0006] Furthermore, one end of the closure is provided with a lower hook that is adapted to the upper hook and accommodates the wire, and the other end is provided with a winding post and a guide post.

[0007] Furthermore, the hook-and-rebound device includes a hook rod hinged to the hook body via a hinge rod, a positioning post provided on the closed part, and a first spring. One end of the hook rod is provided with a positioning groove adapted to the positioning post, and the other end is slidably connected to a push rod. One end of the first spring abuts against the hook body, and the other end abuts against the hook rod, with the spring located between the positioning groove and the hinge rod.

[0008] Furthermore, the specific structure of the other end slidably connected to the push rod is as follows: the hook rod is provided with a mounting hole for the push rod to pass through, and the two sides of the hook rod are provided with waist-shaped holes communicating with the mounting hole. One end of the push rod is fixed with a pin, and the two ends of the pin are limited to move within the waist-shaped holes on both sides. The other end of the push rod extends out of the upper hook.

[0009] Furthermore, in the closed state, the torsion spring returns to its original position, the lower hook closes, and a receiving cavity is formed between the lower hook and the upper hook to accommodate and enclose the wire; in the open state, the hook is pulled up to overcome the elastic force of the torsion spring so that the closed part rotates to the positioning groove to hook the positioning post, thereby achieving the limiting of the closed part.

[0010] Furthermore, the hook body is provided with a positioning hole for limiting the first spring, and the first spring abuts against the bottom of the positioning hole.

[0011] Furthermore, the hook body has a rotating pulley on one side of its lower end and a guide plate on the other side.

[0012] The main technical effects of this utility model are reflected in the following aspects: 1: By using the hook-and-rebound device, the closing part can be closed and opened. When open, it is convenient for the drone to hook the upper hook onto the wire. After hooking the wire, the closing part rebounds and closes again, ensuring the safety of high-altitude operations; 2: The drone hangs the hook on the wire. Under the force of the hook itself, the wire touches the push rod, the first spring is overcoming and compressed, and one end of the hook rod with the positioning groove rotates downward, thereby causing the positioning groove to disengage from the positioning post. At this time, the torsion spring resets and drives the closing part to rotate, causing the lower hook to close the upper hook, and then it is in a closed state, realizing the effect of automatically closing the upper and lower hooks when the wire is hung.

[0021] The following specific examples illustrate the implementation of this application. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. This application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The diagram shows a wire hook, comprising a hook body 1 and a steel wire rope 2. A slider 11 is slidably positioned at the upper end of the hook body 1, and the slider 11 is connected to a connecting rod 13 with a hook 12. The hook 12 is used to hook onto a drone. The hook body 1 is provided with several guide pulleys 14, which guide the steel wire rope 2. The hook body 1 also has an upper hook portion 15 for hooking the wire. A closing portion 3 is connected to the hook body 1 via a hinge shaft 16, which closes the upper hook portion 15 and the lower hook portion 31. A receiving cavity 18 is formed between them to accommodate the wire and to wrap the wire to prevent the hook from falling from a height and injuring people on the ground. A torsion spring 19 is sleeved on the hinge shaft 16. One end of the torsion spring 19 abuts against the closing part 3 and the other end abuts against the hook body 1. After the positioning pin 34 is disengaged from the positioning groove 42, the torsion spring 19 closes the closing part 3. One end of the steel wire rope 2 is fixed to the closing part 3 and wound around the guide pulley 14. The other end is fixed to the slider 11. The hook body 1 is also provided with a hooking and rebound device for closing or opening the upper hook part 15.

[0024] The closing part 3 is closed and opened by using a hook-and-rebound device. When open, it is convenient for the drone to hook the upper hook 15 onto the wire. After hooking the wire, the closing part 3 rebounds and closes again, ensuring the safety of high-altitude operations.

[0025] One end of the closing part 3 is provided with a lower hook part 31 that is adapted to the upper hook part 15 and accommodates the wire. After the lower hook part 31 is closed, a receiving cavity 18 for accommodating the wire is formed between them, and the wire is wrapped to prevent the hook from falling from the sky and injuring people on the ground. The other end is provided with a winding post 32 and a guide post 33. The winding post 32 is used to fix the wire rope 2, and the guide post 33 guides the wire rope 2.

[0026] The hook-and-rebound device includes a hook rod 4 hinged to the hook body 1 via a hinge rod 16, a positioning post 34 provided on the closing part 3, and a first spring 41. One end of the hook rod 4 is provided with a positioning groove 42 adapted to the positioning post 34, and the other end is slidably connected to a push rod 43. When an external force presses the push rod 43, the first spring 41 is overcoming and compressed, and one end of the hook rod 4 with the positioning groove 42 rotates downward, thereby causing the positioning groove 42 to disengage from the positioning post 34. At this time, the torsion spring 19 resets and drives the closing part 3 to rotate, causing the lower hook part 31 to close the upper hook part 15. After the external force disappears, the first spring 41 resets.

[0027] One end of the first spring 41 abuts against the hook body 1, and the other end abuts against the hook rod 4. The spring is located between the positioning groove 42 and the hinge rod 16. The hook body 1 is provided with a positioning hole for limiting the first spring 41. The first spring 41 abuts against the bottom of the positioning hole in order to limit the first spring 41 and prevent the first spring 41 from falling off or changing position.

[0028] The other end is slidably connected to the push rod 43. The hook rod 4 has a mounting hole 44 for the push rod 43 to pass through. The hook rod 4 has waist-shaped holes 45 on both sides that communicate with the mounting hole 44. One end of the push rod 43 is fixed with a pin 46. The pin 46 passes through the waist-shaped hole 45 and is fixed to the push rod 43. The two ends of the pin 46 are limited to the waist-shaped holes 45 on both sides. The pin 46 can move left and right appropriately within the waist-shaped hole 45. In this way, the push rod 43 will not be interfered with when it is pressed. The other end of the push rod 43 extends out of the upper hook part 15. The function here is that when the hook is hung on the wire, the weight of the hook itself is equivalent to pressing the push rod 43, which realizes the effect of automatically closing the lower hook part 31 and the upper hook part 15.

[0029] In the closed state, the torsion spring 19 returns to its original position, the lower hook 31 closes, and a receiving cavity 18 is formed between the lower hook 31 and the upper hook 15 to accommodate and wrap the wire; in the open state, the hook 12 is pulled up to overcome the elastic force of the torsion spring 19 so that the closed part 3 rotates to the positioning groove 42 to hook the positioning post 34, thereby achieving the limiting of the closed part 3.

[0030] The hook body 1 has a rotating pulley 17 on one side of its lower end, which is used to wind the traction rope, and a guide plate 20 on the other side to facilitate the guidance of the drone.

[0031] Working principle: When this utility model is in the closed state, manually pulling the hook 12 moves the slider 11 upward, pulling the wire rope 2 upward, which in turn drives the lower hook 31 of the closing part 3 to rotate, causing the upper hook 15 to open until the positioning post 34 on the closing part 3 is limited in the positioning groove 42 of the hook rod 4. At this time, it is in the open state. Using a drone, the hook is hung on the wire. Under the force of the hook itself, the wire touches the push rod 43, the first spring 41 is overcoming and compressed, and one end of the hook rod 4 with the positioning groove 42 rotates downward, thereby causing the positioning groove 42 to disengage from the positioning post 34. At this time, the torsion spring 19 resets and drives the closing part 3 to rotate, causing the lower hook 31 to close the upper hook 15, and it is in the closed state again, realizing the effect of automatically closing the upper hook 15 and the lower hook 31 when hanging the wire. When removing it from the wire, the drone pulls the hook 12, the slider 11 moves upward, and the steel wire rope 2 is pulled upward, which in turn drives the lower hook 31 of the closing part 3 to rotate, so that the upper hook 15 opens, until the positioning post 34 on the closing part 3 is limited in the positioning groove 42 of the hook rod 4, realizing the open state, and the utility model can be removed.

[0032] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
