In a specific implementation process, as shown in fig. 5, an included angle between every two of the support columns 42 is 120 degrees, and since the three peripheral hoisting cables 32 are arranged in an equilateral triangle, the included angle between the three support columns 42 is 120 degrees so as to be matched with the positions of the hoisting cables 32.

In a specific implementation process, as shown in fig. 4, each of the clamping cylinders 71 is connected with one of the main lantern rings 41 in a clamping manner, and the main lantern ring 41 is clamped with the clamping cylinder 71 to prevent the main lantern ring 41 from falling down, so that the hoisting cable 32 is ensured to suspend one of the anti-twisting structures 4 every five meters of height; and two adjacent main lantern rings 41 are connected in a clamping manner, so that when the hoisting cable 32 is retracted, the torsion-proof structure 4 below each main lantern ring can be clamped by the previous torsion-proof structure 4, and the hoisting cable cannot fall down.

In a specific implementation, as shown in fig. 4, the limiting column 81, the first toggle arm 84 and the hook arm 85 are made of iron, in order to increase the hardness and the wear resistance thereof (wherein the limiting column 81 also has an effect of being easily absorbed by the magnet 89); the driving arm 86 is made of plastic, and since the driving arm 86 has a small movement range and does not bear a large force, the driving arm 86 is made of plastic in order to reduce the overall weight of the limiting structure 8.

In a specific implementation, as shown in fig. 4, the attraction force of the magnet 89 is greater than the sum of the elastic force of the third spring 82 and the elastic force of the fourth spring 86, when the transmission arm 87 is pushed to the left by the limiting arm 81, the hook arm 85 will press the fourth spring 86, and at this time, the fourth spring 86 has the force pushing the hook arm 85 upwards, this causes the bottom end of the driving arm 87 to push the bottom end of the stopper 81 to the right in turn, the magnet 89 can catch the bottom of the stopper 81, the limiting column 81 needs external force to rebound, and when the lifting cable descends, the gravity of the lifting cable and the hook is relied on, the clamping structure 7 presses the blocking rod 93 downwards, and the blocking rod 93 pulls the limiting column 81 to make the limiting column 81 separate from the magnet 89 and reset by means of the third spring 82.

The working principle of the house building material lifting device provided by the invention is as follows:

when in use, one clamping cylinder 71 is fixed at intervals of five meters on the hoisting cable 32 in the middle, each anti-twisting structure 4 is correspondingly sleeved and connected with the side wall of one clamping cylinder 71, so that a distance of five meters is kept between each anti-twisting structure 4, the main lantern ring 41 is sleeved with the hoisting cable 32 in the middle, the three secondary lantern rings 43 are sleeved and connected with the other hoisting cables 32, the main lantern ring 41 and the secondary lantern rings 43 are supported by the supporting columns 42, three peripheral hoisting cables 32 form an equilateral triangle all the time, so that the three hoisting cables form a whole body and cannot approach to each other, the possibility of winding among the hoisting cables 32 is initially reduced, but the possibility of rotation exists among the three hoisting cables, the limiting rods 47 are arranged in the main lantern ring 41, and the anti-rotation teeth 73 are arranged at the top ends of the limiting rods 47, when the anti-twist structure 4 rotates, the limiting rod 47 can prevent the rotation thereof, that is, when the main collar 41 rotates clockwise, the upper limiting rod 47 will move up and down with the rotation of the anti-rotation teeth 73 and continuously push and pull the push-pull rod 46, the bottom end of the push-pull rod 46 makes a piston motion in the spring cylinder 44 and simultaneously presses the first spring 45, the top end of the lower limiting rod 47 will be engaged with the anti-rotation teeth 73 but will be pushed leftward by the anti-rotation teeth 73, the bottom end of the push-pull rod 46 rotationally connected to the middle of the limiting column 47 is engaged with the inner top surface of the spring cylinder 44, the push-pull rod 46 cannot extend any more, so the limiting rod 47 will be pulled by the push-pull rod 46 and cannot be pushed leftward by the anti-rotation teeth 73, so that the top end of the limiting rod 47 is always engaged with the anti-rotation teeth 73, the three peripheral hoisting cables 32 do not drive the anti-twisting structure 4 to rotate; when the main collar 41 rotates counterclockwise, the top end of the upper limit rod 47 will engage with the anti-rotation teeth 73, but will be pushed leftward by the anti-rotation teeth 73, and the bottom end of the push-pull rod 46 rotatably connected to the middle portion of the restraining post 47 is engaged with the inner top surface of the spring cylinder 44, the push-pull rod 46 cannot extend any more, the stopper rod 47 is pulled by the push-pull rod 46, so that it cannot be pushed leftward by the anti-rotation teeth 73, thus, the top end of the limiting rod 47 is always engaged with the anti-rotation teeth 73, and the lower limiting rod 47 can move up and down along with the rotation of the anti-rotation teeth 73, and continuously pushes and pulls the push-pull rod 46, the bottom end of the push-pull rod 46 performs piston movement in the spring cylinder 44, at the same time, the first spring 45 is compressed, so that the three peripheral hoisting cables 32 do not drive the anti-twist structure 4 to rotate. When the hoisting cable 32 is retracted, the first fixed pulley 51 and the second fixed pulley 52 rotate counterclockwise, the engaging cylinder 71 ascends along with the hoisting cable 32, when the hoisting cable 32 passes through the surface of the ball 63 in the first fixed pulley 51, the second ball 63 rotates, so that the hoisting cable 32 can pass through more easily, when the engaging cylinder 71 passes through the second ball 63, because the engaging cylinder 71 has a conical structure, the second ball 63 is pressed to drive the sleeve column 62 to move inwards, the bottom surface of the sleeve column 62 presses the second spring 61, the second spring 61 contracts slightly, the second ball 63 has an elastic force, the engaging cylinder 71 is buffered, so that damage and bumping are reduced when the engaging cylinder passes through the first fixed pulley 51, and the engaging cylinder 71 ascends along with the hoisting cable 32, the anti-twisting structure 4 is driven to ascend together, the anti-twisting structure 4, the clamping cylinder 71 and the hoisting cables 32 are kept relatively still at the beginning, the first main lantern ring 41 is fixed on the bottom surface of the pulley plate 31, when the second anti-twisting structure 4 ascends to contact with the bottom surface of the first main lantern ring 41, the top surface of the second main lantern ring 41 is clamped into the bottom surface of the first main lantern ring 41, so that the hoisting cables cannot ascend continuously, but the hoisting cables 32 also ascend continuously, the first ball bearings 48 on the inner wall of the secondary lantern ring 43 are rotated by the three peripheral hoisting cables 32, so that the hoisting cables 32 pass through the secondary lantern ring 43 more quickly, the middle hoisting cable 32 ascends synchronously to drive the clamping cylinder 71 to ascend, and the side wall of the clamping cylinder 71 pushes the top surfaces of the two limiting columns 81 in the second main lantern ring 41 in the ascending process, the limiting columns 81 contract inwards to press the third spring 82, the bottom ends of the limiting columns 81 penetrate out of the main lantern rings 41 and enter the first main lantern ring 41, when the bottom ends of the limiting columns 81 contact the magnet 89 in the first main lantern ring 41, the magnet attracts the limiting columns 81, so that the limiting columns cannot be rebounded by the third spring 82, at the moment, the top ends of the limiting columns 81 are no longer in contact with the side wall of the clamping cylinder 71, the clamping cylinder 71 can smoothly get rid of the fact that the torsion-proof structure 4 ascends along with the hoisting cable 32, then the third main lantern ring 41 ascends and is in clamping connection with the bottom surface of the second main lantern ring 41, the connection mode of the torsion-proof structure 4 and the bottom surface of the first main lantern ring 41 is the same as that of the second main lantern ring 41, and the only difference is that the bottom ends of the limiting columns 81 in the third main lantern ring 41 enter the second main lantern ring 41 When the driving arm is engaged with the bottom end of the driving arm 87, the bottom end of the driving arm 87 is pushed by the incoming limiting post 81 until the bottom end of the limiting post 41 is attracted by the magnet 89, in this process, the driving arm 87 drives the first shifting arm 84 and the hook arm 85 to rotate together, the first shifting arm 84 rotates to the right, the hook arm 85 drives the limiting hook 88 to rotate downwards until the limiting hook cannot touch the side wall of the engaging cylinder 71, meanwhile, the hook arm 85 presses the fourth spring 86 downwards, since the limiting post 81 in the third main collar 41 is attracted by the magnet 89 in the second main collar 41, the driving arm 87 cannot move by the bottom end of the limiting post 81 in the third main collar 41, the first shifting arm 84 and the hook arm 85 will remain stationary, and thus the engagement between the third main collar 41 and the second main collar 41 causes the hook in the second main collar 41 to be engaged with the hook The arm 85 and the limit hook 87 are retracted so that the engaging cylinder 71 passing through the second main collar 41 can pass through without any obstacle. Then, the ascending main lantern rings 41 are clamped and connected one by one in the same clamping relation until the last main lantern ring 41 is clamped into the bottom surface of the penultimate main lantern ring 41; when the hoisting cable 32 descends, the first fixed pulley 51 and the second fixed pulley 52 rotate clockwise, the engaging cylinder 71 descends along with the hoisting cable 32, when the hoisting cable 32 passes through the surface of the ball 63 in the first fixed pulley 51, the second ball 63 rotates, so that the hoisting cable 32 can pass through more easily, when the engaging cylinder 71 passes through the second ball 63, because the engaging cylinder 71 is in a conical structure, the second ball 63 is pressed to drive the sleeve column 62 to move inwards, the bottom surface of the sleeve column 62 presses the second spring 61, the second spring 61 contracts slightly, the second ball 63 has elasticity, the engaging cylinder 71 is buffered, so that damage and bumping are reduced when the engaging cylinder passes through the first fixed pulley 51, and the engaging cylinder 71 descends along with the hoisting cable 32, the anti-twist structure 4 passes through the last anti-twist structure 4 smoothly, when the last clamping cylinder 71 reaches the last main sleeve ring 41, the bottom end of the clamping cylinder 71 presses the blocking arm 93 downwards and blocks the clamping cylinder 71 to remain in the last main sleeve ring 41, the limiting hook 72 is clamped into the limiting groove 88, the blocking arm 93 rotates around the rotating shaft 91, the limiting hook 72 cannot be separated from the limiting groove 88 in the descending process due to the action of the limiting hook 72, the blocking arm 93 drives the second shifting arm 92 to rotate rightwards, the top end of the second shifting arm 92 can abut against the limiting block 83 on the side wall of the limiting column 81, the limiting block 83 slides the limiting column 81 rightwards, under the combined action of the pushing force of the second shifting arm 92, the pushing force of the third spring 82 and the pushing force of the driving arm 87 in the last main sleeve ring 41, the bottom end of the limiting column 81 is separated from the attraction force of the magnet 89 and quickly leaves the interior of the penultimate main lantern ring 41, and because of no limitation of the limiting column 81, the last main lantern ring 41 is separated from the penultimate main lantern ring 41 under the pushing of the last engageable barrel 71 and then moves downwards together with the last engaging barrel 71; each last catch pot 71 then carries the last torsion-prevention structure 4 away in turn in the above-described manner of disengagement until the hoisting cable 32 stops descending.
