[0037] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings. These are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the present invention. The following will introduce each embodiment of the present invention in detail with reference to the drawings.

[0038] Embodiment 1

[0039] Please refer to Figures 1 to 11 , the present invention preferably provides a technical solution: a magnetic bracket for preventing falls in building construction, including: a mounting frame 111, a walking and climbing bracket is provided at the bottom of the mounting frame 111; and an exoskeleton leg assembly assembled with the mounting frame 111, which is used to assist the construction worker's legs to perform alternating climbing actions, and a magnetic bracelet assembly is also provided on the mounting frame 111. A piston transmission assembly is connected between the magnetic bracelet assembly and the exoskeleton leg assembly, which is used to generate coordinated actions of hands and feet to complete the alternating climbing process; and a first magnetic arm 211 extends upward from the mounting frame 111, which is used to bend vertically and wrap the building to achieve safe suspension.

[0040] In this application, especially in high-altitude operations in the field of steel buildings such as iron towers and steel structures, by setting a walking and climbing bracket on the mounting frame 111, such as Figure 1 , 2 and as shown in 3, the walking and climbing bracket can provide a moving driving force for the magnetic bracket, and this action mode is an alternating operation, which can assist the construction worker to move and climb at high altitude, and extend various implementation modes;

[0041] When performing a single straight line or simple walking and climbing, the construction worker can complete it in a sitting position by means of the walking and climbing bracket;

[0042] When performing complex high-altitude operations that require the coordinated climbing of the construction worker's limbs, by further setting the exoskeleton leg assembly and the magnetic bracelet assembly, the exoskeleton leg assembly can act on the lower limbs of the construction worker, playing a supporting and assisting role. At the same time, the magnetic bracelet assembly can be taken out and worn on the construction worker's arm. Through the movement of the legs, the arm can act on the steel building in a magnetic adsorption manner to form a temporary support point for the movement of the body;

[0043] The further provided first magnetic arm 211, which is similar to a snake-shaped structure, can be wound and wrapped around the cross beam close to the building. When docking and operating for a long time, it can provide safe suspension for the magnetic bracket, effectively reducing the risk of its fall and further ensuring the safety of the construction worker.

[0044] Embodiment 2

[0045] As another embodiment of the present invention, the walking and climbing bracket includes two mounting bars 313 assembled at the bottom of the mounting frame 111. A rotatable mounting rod 316 is horizontally mounted between the two mounting bars 313. The two ends of the mounting rod 316 respectively penetrate through the mounting holes formed in the two side mounting bars 313 and are respectively fixed with two first transmission rods 312 that are symmetrically arranged up and down. And a second gear 315 fixed to the mounting bar 313 with the mounting rod 316 as the center. A first gear 314 meshing with the second gear 315 is assembled on the first transmission rod 312. A support rod 311 is rotatably mounted at the end of the two first transmission rods 312 with the first gear 314 as the center. Magnetic suction bodies are provided at the ends of the two support rods 311 away from the first transmission rod 312. And a deflectable second transmission rod 320 is mounted at the end of the mounting bar 313 away from the second gear 315. The end of the second transmission rod 320 away from the mounting bar 313 is rotatably connected to the support rod 311 through a pin shaft. And a first motor 319 fixed to the inner side of one of the mounting bars 313. A second transmission gear 318 is mounted at the output end of the first motor 319. And a first transmission gear 317 fixed to the mounting rod 316 and meshing with the second transmission gear 318.

[0046] Further, each magnetic suction body includes a connecting rod 321 fixed to the end of the support rod 311. A second motor 322 is assembled at the end of the connecting rod 321 away from the support rod 311. A pedal 323 is fixed to the output end of the second motor 322. The pedal 323 has a "C" - shaped structure. An electromagnetic suction cup 324, a first electromagnetic plate 325 are respectively arranged on the front end face of the pedal 323. And second magnetic suction arms 611 are assembled on the inner top and bottom of the pedal 323, which are used for laterally adapting to bend and wrap the building to achieve safe support. A second contact sensor 911 is also arranged on the front end face of each pedal 323, which is used to control the operation of the electromagnetic suction cup 324 and the first electromagnetic plate 325 on the corresponding side.

[0047] In this embodiment, a walking and climbing bracket and a magnetic suction body are provided, and magnetic - suction climbing on the surface of a steel building is realized by alternately moving and the alternating operation of the magnetic suction body;

[0048] Specifically, as Figure 1 、 2As shown in FIGS. 3 and 6, for the walking and climbing bracket, when the first motor 319 operates, since the second transmission gear 318 meshes with the first transmission gear 317 for transmission, the mounting rod 316 can be further driven to rotate. Due to the symmetrical arrangement of the first transmission rods 312 and the second transmission rods 320 on both sides in the vertical direction, under the parallelogram structure formed by the mounting strip 313, the first transmission rods 312, the second transmission rods 320, and the support rods 311, when the support rod 311 moves to below the mounting strip 313, the support rod 311 on the other side correspondingly moves to above the mounting strip 313. Repeating this process can achieve alternating stepping;

[0049] Under the action of the second contact sensor 911, it is known that a single magnetic chuck body can completely support the entire magnetic adsorption bracket and construction workers. As Figure 2 shown, when the walking and climbing bracket power supply operates, when the electromagnetic chuck 324 on one side adsorbs to the first electromagnetic plate 325 on the surface of a steel building and is normal, a pressure value will be generated on the second contact sensor 911. The second contact sensor 911 transmits the signal to the single-chip microcomputer. The single-chip microcomputer receives the signal and controls the electromagnetic chuck 324 on the other side to release the adsorption with the first electromagnetic plate 325 and perform its own feeding until it completely adsorbs to the steel building again. The former electromagnetic chuck 324 and the first electromagnetic plate 325 repeat this action. Repeating this process can achieve the alternating climbing action of magnetic adsorption.

[0050] Embodiment 3

[0051] As other embodiments of the present invention, to reinforce the reliability and safety of the magnetic adsorption bracket, a first magnetic adsorption arm 211 and a second magnetic adsorption arm 611 are further provided. The first magnetic adsorption arm 211 and the second magnetic adsorption arm 611 have the same structural principle. The structure of the second magnetic adsorption arm 611 includes a mounting frame 6113 and a number of driving blocks 6119 connected end to end. Third electromagnetic plates 6111 are provided on several driving blocks 6119 except the last one. The sizes of the several driving blocks 6119 and the third electromagnetic plates 6111 gradually decrease in the direction away from the mounting frame 6113. One end of a driving block 6119 is provided with a limiting rotating shaft 6120, and the other end is provided with a limiting rotating groove 6121. The limiting rotating shaft 6120 on the latter driving block 6119 rotates in the limiting rotating groove 6121 of the previous driving block 6119, and the limiting rotating shaft 6120 located in the limiting rotating groove 6121 where the first driving block 6119 is located is rotationally assembled with the limiting rotating shaft 6120 provided on the mounting frame 6113. Third motors 6114 are respectively assembled on both sides of the mounting frame 6113, wire wheels 6115 connected to the output ends of the third motors 6114, and steel wire ropes 6117 that sequentially penetrate through several driving blocks 6119 and are arranged on their left and right sides. One end of the steel wire rope 6117 extends into the mounting frame 6113 and is connected to the corresponding wire wheel 6115. The other end thereof penetrates through the last driving block 6119 and is provided with an end block 6116. A spring 6122 is provided on the outer wall of the steel wire rope 6117 between the last driving block 6119 and the previous driving block 6119, and a third contact sensor 6118 is provided at a position on the last driving block 6119 close to the spring 6122. When the third contact sensor 6118 is stressed, it is used to control the energization of several third electromagnetic plates 6111. When the force on the third contact sensor 6118 is lost, it is used to control the power-off of several third electromagnetic plates 6111.

[0052] In this embodiment, through the further provided first magnetic adsorption arm 211 and second magnetic adsorption arm 611, as Figure 2 , the first magnetic adsorption arm 211 acts on the top of the mounting rack 111, and it can be bent and wound in the vertical direction and wrapped around the surface of the building. The building can be a cylinder, a prism, a support beam, etc., and is used for suspension. The second magnetic adsorption arm 611 acts on the pedal 323 and is horizontally arranged, and can be wound circumferentially and wrapped around the surface of the building to play a further fixing role;

[0053] Specifically, taking the structure of the second magnetic adsorption arm 611 as an example, as Figure 9 、 10As shown in FIG. 11, since it is composed of a number of drive blocks 6119 connected end to end, and the dimensions of a number of drive blocks 6119 and the third electromagnetic plate 6111 decrease in sequence along the direction away from the mounting frame 6113, and the limit rotating shaft 6120 on the latter drive block 6119 rotates in the limit rotating groove 6121 of the previous drive block 6119. When construction workers need to dock at high altitude, according to the structure of adjacent buildings, the third motor 6114 on the corresponding side is controlled to wind and unwind the wire rope 6117. A number of drive blocks 6119 bend along the direction in which the wire rope 6117 shortens and retract inward to wrap around the perimeter of the building with a corresponding shape;

[0054] As Figure 10 , 11 , when combined with the third electromagnetic plate 6111 and the third contact sensor 6118, when a number of drive blocks 6119 complete the winding of the building, the drive block 6119 at the corresponding end will approach the adjacent drive block 6119 and cause extrusion to the third contact sensor 6118. The third contact sensor 6118 transmits the first signal to the single-chip microcomputer and controls a number of third electromagnetic plates 6111 to be energized, thereby generating magnetic force and firmly wrapping around the perimeter of the building, effectively reducing the risk of falling;

[0055] When it needs to be released, the third motor 6114 is controlled to drive in the reverse direction. Since no third electromagnetic plate 6111 is provided on the end drive block 6119, it can be reset under the action of the spring 6122. At this time, the third contact sensor 6118 loses the pressure effect. The third contact sensor 6118 transmits the second signal to the single-chip microcomputer and controls a number of third electromagnetic plates 6111 to be powered off. A number of third contact sensors 6118 release the magnetic attraction effect, and the corresponding second magnetic attraction arm 611 can be separated from the building and reset.

[0056] Embodiment 4

[0057] As other embodiments of the present invention, the exoskeleton leg assembly includes a battery compartment 112 assembled on the mounting frame 111. A backrest 113 is installed at the front of the battery compartment 112, and a seat plate 114 connected to the backrest 113. It also includes a bone bracket assembled on both sides of the backrest 113. A net bag is connected between the bone bracket and the end of the seat plate 114;

[0058] Further, the bone bracket includes a support member 425 fixed to the backrest 113. An end of the support member 425 away from the mounting bracket 111 is connected with a fitting 424, and a support plate 422 rotatably mounted with the fitting 424. A strap 423 is arranged on the support plate 422 for binding the support plate 422 under the thighs of the construction worker. A fixing member 420 is fixed to the outer wall of the front part of the support plate 422, and a connecting member 421 is rotatably mounted with the fixing member 420. A first mounting member 417 is fixed to the top of the fitting 424. An end of the first mounting member 417 is rotatably connected with a piston sleeve 415, and an electric telescopic rod 419 is assembled on the lower end face of the piston sleeve 415. The execution end of the electric telescopic rod 419 is fixed to the connecting member 421, and the electric telescopic rod 419 is connected to the output end of the mounting bracket 111 through an electric wire.

[0059] In this embodiment, an exoskeleton leg assembly is provided. As Figure 1 、 3 , it provides a backrest 113 and a seat board 114, which can form a seat structure, facilitating the sitting and construction movement of the construction worker. At the same time, a bone bracket is further provided, which can provide assistance for the construction worker to bend the knees and lift the legs to climb upwards, in order to better adapt to the relatively complex high-altitude construction environment.

[0060] Specifically, for the bone bracket, as Figure 3 、 5 、shown in 7, first, the construction worker sits on the seat board 114, with the back against the backrest 113. The support plates 422 on both sides are placed under the thighs of the construction worker and are bound through the straps 423. When a climbing assistance action is required, controlling the telescopic movement of the electric telescopic rod 419 can drive the support plate 422 to deflect around the fitting 424 to achieve the leg assistance action.

[0061] Further, the magnetic bracelet assembly includes an outer sleeve 4111 and second electromagnetic plates 411 annularly distributed on the outer sleeve 4111. An inner frame 4113 is further arranged inside the outer sleeve 4111, and an inner sleeve 412 is assembled with the inner frame 4113. Telescopic and movable pressing plates 414 are annularly distributed on the inner sleeve 412. A shrapnel 4141 is connected between each pressing plate 414 and the outer wall of the inner sleeve 412. A first contact sensor 4112 is arranged on the inner wall of the second electromagnetic plate 411. When the pressing plate 414 expands outwards and acts on the first contact sensor 4112, it is used to control the energization of the second electromagnetic plate 411. When the pressing plate 414 contracts inwards and disengages from the first contact sensor 4112, it is used to control the power-off of the second electromagnetic plate 411. A plug post 413 is arranged on the support rod 311, facilitating the placement of the magnetic bracelet assembly.

[0062] Further, the piston drive assembly includes a pipe orifice 416 provided at the upper part of the piston sleeve 415, a conduit 4161 connecting the pipe orifice 416 and the inner sleeve 412, and a piston rod 418 piston - assembled with the piston sleeve 415. The piston rod 418 is parallel to the electric telescopic rod 419, and the end of the piston rod 418 away from the piston sleeve 415 is connected to the connecting member 421. When the support plate 422 drives the legs of the construction worker to move, the piston rod 418 moves piston - like within the piston sleeve 415. Under the connection action of the conduit 4161, the pressing plate 414 where the inner sleeve 412 is located is controlled to contract and expand.

[0063] Since there is a piston drive assembly connected between the magnetic - adsorption bracelet assembly and the exoskeleton leg assembly, as Figure 7 、 8 、9 shown, when the support plate 422 assists the construction worker to bend the knee and lift the leg upward for climbing, under the action of the piston drive assembly, the piston rod 418 moves within the piston sleeve 415 in the direction close to the first mounting member 417, squeezing the air flow within the piston sleeve 415 to enter the interior of the second electromagnetic plate 411 through the conduit 4161. At this time, the air flow makes the interior of the inner sleeve 412 full and further makes the circumferentially arranged pressing plate 414 expand outward, thereby squeezing the first contact sensor 4112, and then controlling the second electromagnetic plate 411 to be energized to generate magnetism, that is, the magnetic - adsorption bracelet assembly on the same - side arm has magnetism and can be adsorbed and fixed on the building as a support point. At this time, the corresponding - side exoskeleton leg assembly is in the extended state, and the corresponding piston rod 418 moves within the piston sleeve 415 in the direction away from the first mounting member 417, generating negative pressure within the piston sleeve 415. The air flow within the inner sleeve 412 flows back into the piston sleeve 415. Under the elastic force of the elastic piece 4141, the pressing plate 414 resets, and the first contact sensor 4112 loses the acting force, and the magnetic - adsorption bracelet assembly on this side releases magnetism, and the arm can perform an upward climbing movement. When the extended - state exoskeleton leg assembly bends the knee and lifts the leg upward for climbing, the magnetic - adsorption bracelet assembly on the same side generates magnetism, which is used to magnetically adsorb the arm to the building surface to form another support point. In this way, by alternating in a cycle, the coordinated climbing process of the limbs can be realized.
