DETAILED DESCRIPTION

[0035] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0036] Example:

[0037] like Figure 1 As shown, in order to solve the above problems, this embodiment discloses a claw-type anchor point, including:

[0038] A supporting main pole 10, with hoisting parts 100 for hoisting a drone at both ends of the supporting main pole 10;

[0039] A first clamping member 20, the first clamping member 20 is slidably disposed at one end of the supporting main rod 10;

[0040] A second clamping member 30, the second clamping member 30 is fixedly disposed at the other end of the supporting main rod 10;

[0041] A rope fixing portion 21 is provided on one side of the first clamping member 20, and two traction ropes 22 are provided on the rope fixing portion 21. A pair of first guide wheel assemblies 31 and a pair of second guide wheel assemblies 32 for guiding the two traction ropes 22 are provided on the second clamping member 30. One ends of the two traction ropes 22 are respectively connected to the rope fixing portion 21, and the other ends are respectively guided by the first guide wheel assembly 31 and the second guide wheel assembly 32. When the two traction ropes 22 are pulled, the first clamping member 20 approaches the second clamping member 30 along the supporting main rod 10, and cooperates with the second clamping member 30 to clamp the roof wall of the high-rise building.

[0042] When the utility model is in use, the two traction ropes 22 are pulled downward, so that the force on the traction ropes 22 is guided through the first guide wheel assembly 31 and the second guide wheel assembly 32, and acts on the first clamping member 20, so that the first clamping member 20 is close to the second clamping member 30 along the supporting main rod 10 after receiving the force on the traction rope 22, so that the first clamping member 20 and the second clamping member 30 are clamped together, so that the first clamping member 20 and the second clamping member 30 can be clamped on the roof wall of the high-rise building. At the same time, a hoisting part 100 for drone hoisting is set at both ends of the supporting main rod 10, and the hoisting part 100 can be grasped by the grabber on the drone, so that the utility model can be transported to the designated location by the drone, and it is no longer necessary to climb to the roof for installation, which greatly saves rescue time.

[0043] The invention solves the problem that the current high-rise rescue device needs personnel to go to the roof to fix one end of the traction rope 22 on the roof before it can be used, and expansion bolts and lifting rings need to be driven into the wall to complete the fixing of the traction rope 22, which is inconvenient to install and use.

[0044] In order to facilitate the first clamping member 20 to slide on the supporting main rod 10, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that the first clamping member 20 includes a sliding sleeve 200, a first mounting frame 201 and a first clamping plate 202. The sliding sleeve 200 is slidably set at one end of the supporting main rod 10, one end of the first mounting frame 201 is fixedly connected to the sliding sleeve 200, and the first clamping plate 202 is fixedly set at the other end of the first mounting frame 201.

[0045] The setting of the sliding sleeve 200 can make the first clamping member 20 slide along the supporting main rod 10 , so that the first clamping member 20 can approach the second clamping member 30 along the supporting main rod 10 and cooperate and fix with the second clamping member 30 .

[0046] like Figures 2 to 3As shown, in order to solve the problem that the first clamping member 20 slides reversely on the supporting main rod 10 during use, causing the fixation to loosen and leading to rescue failure, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that a limit assembly 203 is provided on the sliding sleeve 200, and the limit assembly 203 includes a limit card 204, a connecting rotating rod 205, a torsion spring 206 and a knob 207. One end of the connecting rotating rod 205 passes through the upper end of the sliding sleeve 200 and is rotatably connected to the sliding sleeve 200. The knob 207 is arranged at the other end of the connecting rotating rod 205. The limit card 204 is arranged in the sliding sleeve 200, and one end is fixedly connected to the connecting rotating rod 205. Then, the knob 207 torsion spring 206 is arranged on the connecting rotating rod 205, and one end is fixedly connected to the sliding sleeve 200, and the other end is fixedly connected to the knob 207. The upper end of the supporting main rod 10 is provided with a plurality of limiting protrusions 208 which are arranged in cooperation with the limiting card 204. When the sliding sleeve 200 slides toward the second clamping member 30, the limiting card 204 drives the connecting rotating rod 205 and the torsion spring 206 to rotate through the plurality of limiting protrusions 208. When the sliding sleeve 200 slides in the direction away from the second clamping member 30, the limiting card 204 forms a card connection with the limiting protrusion 208 under the action of the torsion spring 206, so as to limit the sliding sleeve 200 from sliding in the direction away from the second clamping member 30.

[0047] When in use, a plurality of slots are formed between the plurality of limiting protrusions 208. When the first clamping member 20 approaches the second clamping member 30, the limiting card 204 can be lifted and slid normally, and the torsion spring 206 is in a process of being compressed and released continuously; when the first clamping member 20 is away from the second clamping member 30, one end of the limiting card 204 is limited by the slot formed between the limiting protrusions 208 under the reset force of the torsion spring 206, thereby limiting the reverse movement of the first clamping member 20, thereby increasing the stability of the fixation. After the rescue is completed, the first clamping member 20 can be moved in the direction by simply turning the knob 207 to compress the torsion spring 206.

[0048] Among them, the second clamping member 30 includes a fixing sleeve 300, a second mounting frame 301 and a second clamping plate 302, the fixing sleeve 300 is fixedly set at the other end of the supporting main rod 10, one end of the second mounting frame 301 is fixedly connected to the fixing sleeve 300, and the second clamping plate 302 is set at the other end of the second mounting frame 301.

[0049] In order to enhance the stability of the present invention when in use, and thus improve the load-bearing capacity of the present invention, this embodiment is modified on the basis of the above embodiment, and the difference from the above embodiment is that the first mounting frame 201 includes a first L-shaped frame 209 and a first reinforcing rod 210, one end of the first L-shaped frame 209 is fixedly connected to the sliding sleeve 200, and the other end is fixedly connected to the first clamping plate 202, one end of the first reinforcing rod 210 is fixedly connected to one end of the first L-shaped frame 209, and the other end is fixedly connected to the other end of the first L-shaped frame 209, and a triangular structure is formed between the first L-shaped frame 209 and the first reinforcing rod 210;

[0050] The second mounting frame 301 includes a second L-shaped frame 310 and a second reinforcing rod 311. One end of the second L-shaped frame 310 is fixedly connected to the fixing sleeve 300, and the other end is fixedly connected to the second clamping plate 302. One end of the second reinforcing rod 311 is fixedly connected to one end of the second L-shaped frame 310, and the other end is fixedly connected to the other end of the second L-shaped frame 310. A triangular structure is formed between the second L-shaped frame 310 and the second reinforcing rod 311.

[0051] The triangular structure can be more stable, so that the utility model can have a higher load-bearing capacity.

[0052] like Figure 4 As shown, in order to facilitate the guiding of the traction rope 22, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that a pair of first guide wheel assemblies 31 are respectively arranged on both sides of the fixed sleeve 300, and the first guide wheel assembly 31 includes a first guide wheel body 303 and a first fixed link 304. One end of the first fixed link 304 is fixedly connected to the fixed sleeve 300, and the first guide wheel body 303 is rotatably arranged at the other end of the first fixed link 304.

[0053] Among them, the second mounting frame 301 is provided with a fixed mounting rod 305 for mounting the second guide wheel assembly 32, and a pair of second guide wheel assemblies 32 are respectively arranged on both sides of the fixed mounting rod 305. The second guide wheel assembly 32 includes a second guide wheel body 306 and a second fixed connecting rod 307. One end of the second fixed connecting rod 307 is fixedly connected to the fixed mounting rod 305, and the second guide wheel body 306 is rotatably arranged at the other end of the second fixed connecting rod 307.

[0054] By setting the first guide wheel assembly 31 and the second guide wheel assembly 32, one end of the traction rope 22 can be pulled to drive the first clamping member 20 to approach the second clamping member 30. At the same time, when lifting heavy objects, the traction rope 22 can also continue to apply force to the first clamping member 20 to prevent the first clamping member 20 and the second clamping member 30 from detaching from the roof wall of the high-rise building.

[0055] In order to prevent the traction rope 22 from being separated from the first guide wheel body 303 and the second guide wheel body 306, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that a first limiting frame 308 is provided at the upper end of the first guide wheel body 303, and one end of the first limiting frame 308 is fixedly connected to the first fixed link 304. The first limiting frame 308 is used to limit the traction rope 22 from being separated from the first guide wheel body 303;

[0056] A second limiting frame 309 is provided at the upper end of the second guide wheel body 306 . One end of the second limiting frame 309 is fixedly connected to the second fixed link 307 . The second limiting frame 309 is used to limit the traction rope 22 from detaching from the second guide wheel body 306 .

[0057] When in use, the arrangement of the first limiting frame 308 and the second limiting frame 309 can effectively prevent the traction rope 22 from being separated from the first guide wheel body 303 and the second guide wheel body 306 .

[0058] In order to further enhance the stability of the first clamping member 20 and the second clamping member 30 in clamping the roof wall of the high-rise building, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that a plurality of fixing members 33 are provided on the first clamping plate 202 and the second clamping plate 302, and a placement plane 34 is provided at the bottom of the supporting main rod 10, and the placement plane 34 can contact the roof wall of the high-rise building.

[0059] The fixing member 33 can be a sharp protrusion structure, so that after the first clamping plate 202 and the second clamping plate 302 are clamped and fixed with the roof wall of the high-rise building, they can be inserted into the wall to increase the clamping stability of the first clamping plate 202 and the second clamping plate 302. At the same time, the matching arrangement of the placement plane 34 and the fixing member 33 can avoid the problem of tilting of the utility model when in use.

[0060] like Figure 5 , Figure 6As shown, a high-rise rescue device includes the above-mentioned claw-type anchor point, and also includes a third guide wheel assembly 40 and a winding mechanism 50. The third guide wheel assembly 40 includes a third guide wheel body 400 and a third fixed link 401. The third guide wheel body 400 is rotatably set on the third fixed link 401. The two ends of the third fixed link 401 are respectively detachably connected to two traction ropes 22. A hanging rope 402 is provided on the third guide wheel body 400. One end of the hanging rope 402 is wound by the winding mechanism 50, and the other end is guided by the third guide wheel body 400. The end of the hanging rope 402 guided by the third guide wheel body 400 is provided with a hook 403. The third guide wheel body 400 is provided with a third limiting frame 404. One end of the third limiting frame 404 is fixedly connected to the third fixed link 401. The third limiting frame 404 is used to limit the hanging rope 402 from detaching from the third guide wheel body 400. The winding mechanism 50 can be set on the fire truck 60.

[0061] The winding mechanism 50 can adopt a winding machine in the prior art that can realize the functions of the utility model.

[0062] The winding mechanism 50 at least includes a mounting frame, a winding drum rotatably connected to the mounting frame, and a driving structure arranged on one side of the mounting frame for driving the winding drum to wind up the hanging rope 402 and thus lift the heavy object.

[0063] The driving structure can adopt a brake motor in the prior art that can realize the function of the utility model.

[0064] When in use, the winding mechanism 50 is used to wind up one end of the hanging rope 402, so that the hook 403 at the other end of the hanging rope 402 can hook the heavy object and lift it, thereby realizing the transportation of materials. At the same time, the utility model can also be used to complete the rescue of people.

[0065] like Figure 7 As shown, a labor-saving pulley block in the prior art that can realize labor-saving can be arranged on the third guide wheel assembly 40. Thus, the utility model can hoist heavier objects.

[0066] Working principle of this utility model:

[0067] When the utility model is in use, the two traction ropes 22 are pulled downward, so that the force on the traction ropes 22 is guided through the first guide wheel assembly 31 and the second guide wheel assembly 32, and acts on the first clamping member 20, so that the first clamping member 20 is close to the second clamping member 30 along the supporting main rod 10 after receiving the force on the traction rope 22, so that the first clamping member 20 and the second clamping member 30 are clamped together, so that the first clamping member 20 and the second clamping member 30 can be clamped on the roof wall of the high-rise building. At the same time, a hoisting part 100 for drone hoisting is set at both ends of the supporting main rod 10, and the hoisting part 100 can be grasped by the grabber on the drone, so that the utility model can be transported to the designated location by the drone, and it is no longer necessary to climb to the roof for installation.

[0068] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
