[0002] In water rescues, fires, and rescues of people trapped on cliffs in the wild, it is often necessary to throw rescue ropes to the trapped people. However, if rescuers throw the rescue ropes by hand, due to the limitations of human strength and skills, they can only throw them a maximum of about 20 meters. Therefore, rescue robots are usually used to throw the ropes.
[0003] When rescue robots are conducting rescue operations, they not only need to launch the rope, but also need the rope to be firmly positioned on the anchor post. Therefore, the end of the rope of the rescue robot's rope launcher is often connected to a grappling hook. In order for the grappling hook to firmly grip the terrain, the grappling hook is often opened at a certain angle. This makes the grappling hook take up a lot of space when stored and inconvenient to carry, resulting in poor practicality.
[0004] Therefore, it is necessary to provide a new hook for a rope thrower for rescue robots to solve the above-mentioned technical problems. Summary of the Invention

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A schematic diagram of a preferred embodiment of the special hook for the rope thrower of the rescue robot provided by this utility model; Figure 2 for Figure 1 The diagram shown is a schematic of the device in its retracted state. Figure 3 for Figure 1 The schematic diagram of the sliding hole and through groove structure is shown below;
[0024] Figure 4 for Figure 1 The diagram shows the structure of the vertical and horizontal sliding grooves. The special hook for the rope thrower of the rescue robot includes: a first mounting post 1, an automatic ejection mechanism, and a hook retraction mechanism;
[0025] Mounting pieces 2, there are multiple mounting pieces 2, all of which are horizontally fixedly connected to the outer surface of the first mounting post 1. Each mounting piece 2 has a hook 3 rotatably connected to its outer end. An automatic pop-out mechanism is set at the bottom end of each hook 3, and a hook retraction mechanism is set inside the first mounting post 1.
[0026] The second mounting post 5 is fixedly connected to the bottom end of the first mounting post 1.
[0027] The bottom ends of multiple hooks 3 are provided with anti-slip teeth 4, and the inner ends of multiple hooks 3 are fixedly connected with limit blocks 18.
[0028] Multiple hooks 3 are bent downwards, and anti-slip teeth 4 are evenly distributed along the length of each hook 3 on the bottom surface of each hook 3. After the hook 3 grips the terrain, the anti-slip teeth 4 can prevent the hook 3 from detaching from the terrain, thus improving the stability of the device.
[0029] The limiting block 18 acts as a limiter, restricting the maximum extension angle of the hook 3 in the device and preventing it from coming off after gripping the terrain.
[0030] The hook retraction mechanism includes a sliding hole 9 vertically opened at the top of the first mounting post 1. A slider 11 is slidably connected inside the sliding hole 9. A second spring 12 is provided between the slider 11 and the bottom end of the sliding hole 9. A plurality of through slots 10 are horizontally opened on the outer surface of the first mounting post 1, each corresponding to a plurality of hooks 3. The plurality of through slots 10 are all connected to the inside of the sliding hole 9. A locking block 14 extending to the outside of the first mounting post 1 is vertically slidably connected inside each through slot 10. The inner end of each locking block 14 is fixedly connected to the outer surface of the slider 11.
[0031] The top of the slider 11 is rotatably connected to a rotating disk 13 that matches the inner diameter of the sliding hole 9. The outer ring surface of the rotating disk 13 is fixedly connected to a buckle 15. The inner wall of the sliding hole 9 is vertically provided with a vertical sliding groove 16 that extends to its top and matches the buckle 15. The bottom end of the vertical sliding groove 16 is horizontally provided with a horizontal sliding groove 17.
[0032] When not in use, the multiple hooks 3 can be retracted. When retracting, the hooks 3 need to be held and pressed towards the first mounting post 1. After all the hooks 3 are retracted, the slider 11 can be pressed down. During the downward movement of the slider 11, the multiple locking blocks 14 also move downward. During this process, the latches 15 on the rotating disk 13 will move downward along the length of the vertical slide groove 16 inside the vertical slide groove 16 until the bottom of the vertical slide groove 16. At this time, the rotating disk 13 can be rotated to make the latches 15 engage in the horizontal slide groove 17. Under the restriction of the latches 15, the slider 11 cannot move upward, and the multiple locking blocks 14 also cannot move upward. Under the obstruction of the locking blocks 14, the multiple hooks 3 will also remain in the retracted state and cannot be opened. In this state, the storage and transportation of the device becomes more convenient.
[0033] The second mounting post 5 is fixedly connected to the bottom end of the first mounting post 1;
[0034] The automatic pop-out mechanism includes a first mounting block 6 fixedly connected to the bottom of multiple hooks 3, and multiple second mounting blocks 7 corresponding to the multiple first mounting blocks 6 respectively, which are laterally fixedly connected to the outer surface of the second mounting post 5. A first spring 8 is provided between the first mounting block 6 and the corresponding second mounting block 7, and the two ends of the first spring 8 are rotatably connected to the outer ends of the first mounting block 6 and the second mounting block 7 respectively.
[0035] When the device is needed, the rotating disk 13 can be rotated in the opposite direction until the latch 15 disengages from the horizontal slide groove 17. At this time, under the action of the second spring 12, the slider 11 moves upward, and the multiple latches 14 also move upward in sync. The latches 14 no longer limit the multiple hooks 3. Under the action of the multiple first springs 8, the multiple hooks 3 automatically pop outward until the multiple hooks 3 reach the maximum opening angle. At this time, the launcher can be used to launch the device outward to rescue the trapped personnel.
[0036] A lever 19 is fixedly connected to the upper surface of the rotating disk 13.
[0037] The bottom end of the second mounting column 5 is vertically fixed with a connecting rod 20.
[0038] The lever 19 facilitates the rotation of the rotating disc 13, and the connecting rod 20 is used for telescopic connection.
[0039] The working principle of the special hook for the rope thrower of the rescue robot provided by this utility model is as follows:
[0040] After the device is installed, during normal storage, the multiple hooks 3 can be tightened to press the slider 11 down into the first mounting post 1, and the rotating disk 13 can be rotated to make the buckle 15 engage in the horizontal sliding groove 17. At this time, the multiple hooks 3 of the device will be in a tightened state, which is convenient for storage and transportation. When the device needs to be used, the rotating disk 13 is rotated in the opposite direction, and the multiple hooks 3 of the device will automatically pop out, and the staff can throw the device out.
[0041] Compared with related technologies, the special hook for the rope thrower of the rescue robot provided by this utility model has the following beneficial effects:
[0042] This utility model provides a special hook for a rope thrower for rescue robots. By setting an automatic pop-out mechanism and a hook retraction mechanism, the hook 3 of the device is rotatably connected to the outer surface of the first mounting post 1. When not in use, multiple hooks 3 can be retracted. After retraction, push the slider 11 downward and rotate the rotating disk 13 so that the buckle 15 of the rotating disk 13 is engaged in the horizontal sliding groove 17. At this time, under the limit of multiple locking blocks 14, multiple hooks 3 cannot be opened and always remain in the retracted state. In this state, the device is relatively small in size, which is convenient for storage and transportation. When needed, simply rotate the rotating disk 13 in the opposite direction. The overall use is more convenient, thereby improving the practicality of the device.
