The cable 23 located on the outer surface of the second guide wheel 26 is hinged to the outer surface of the second winch drum 27. The cable 23 located on the outer surface of the first guide wheel 25 is hinged to the outer surface of the first winch drum 28. When it is necessary to lift the building materials, the motor 20 is started. The output end of the motor 20 drives the second winch drum 27 and the first winch drum 28 to rotate. The first winch drum 28 and the second winch drum 27 drive the cable 23 to rotate. When the first winch drum 28 and the second winch drum 27 rotate clockwise, the first winch drum 28 rotates clockwise. The cable 23 on the surface of the drum 28 is wound up by the first guide wheel 25 and the pulley 22, and the cable 23 on the surface of the second winch drum 27 is released by the second guide wheel 26 and the pulley 22. Since there is a diameter difference between the second winch drum 27 and the first winch drum 28, the lifting plate 21 will be driven to lift, and its lifting speed is related to the diameter difference between the second winch drum 27 and the first winch drum 28. The output end of the motor 20 rotates counterclockwise, and the cable 23 drives the lifting plate 21 to move downward through the second guide wheel 26, the first guide wheel 25 and the pulley 22, thereby achieving the purpose of lifting construction materials.
[0017] The inner support device 3 includes two first transmission plates 31, one end of the two first transmission plates 31 is commonly connected with the first connecting shaft 30, the bottom end of the sleeve rod 211 is sleeved with the outer surface of the first connecting shaft 30, the other end of the two first transmission plates 31 is rotatably connected with the second transmission plate 32, the outer surface of the two second transmission plates 32 is commonly connected with the second connecting shaft 33, the bottom ends of the two second transmission plates 32 are rotatably connected with the sliding shaft 34, one end of the two sliding shafts 34 is respectively connected with the first movable plate 35 and the second movable plate 37, the outer surface of the first movable plate 35 is provided with a first through groove 36, the outer surface of the second movable plate 37 is provided with a second through groove 38, one sliding shaft 34 penetrates the first through groove 36, the other sliding shaft 34 penetrates the second through groove 38, the bottom ends of the first movable plate 35 and the second movable plate 37 are fixedly connected with a fixed block 39, one end of the two fixed blocks 39 is rotatably connected There are support plates 40. When it is necessary to hoist the building materials, the inner support device 3 is lowered by the lifting device 2 to place the two support plates 40 between the inner diameters of the building materials. Then, the inner support device 3 is driven to lift by the lifting device 2. The lifting force causes the two first transmission plates 31 to rise through the first connecting shaft 30. As the angle between the two rising first transmission plates 31 continues to decrease, the two second transmission plates 32 are driven to move the bottom ends of the two second transmission plates 32 horizontally toward each other through the second connecting shaft 33. One of the sliding shafts 34 drives the second moving plate 37 to move horizontally to the right through the first through groove 36 in the first moving plate 35, and the other sliding shaft 34 drives the first moving plate 35 to move horizontally to the left through the second through groove 38 in the second moving plate 37, thereby fixing the building materials with the two support plates 40 through the inner support, so as to achieve the purpose of taking the building materials while lifting.
[0018] The diameter of the first capstan 28 is greater than the diameter of the second capstan 27. The winding direction of the cable 23 located on the outer surface of the second capstan 27 is opposite to the winding direction of the cable 23 located on the outer surface of the first capstan 28. The first guide wheel 25 is higher than the second guide wheel 26. The center point of the pulley 22 is on the same vertical horizontal line as the center points of the second capstan 27 and the first capstan 28. The purpose is to facilitate the cable 23 to pass through the diameter difference between the first capstan 28 and the second capstan 27, thereby driving the cable 23 to rotate with different circumferences. The oppositely wound cables 23 are wound up at one end of the first capstan 28 and released at one end of the second capstan 27, thereby achieving the movement of the lifting cable 23. The raised first guide wheel 25 facilitates the sliding guide function through the cooperation of the pulley 22 located at the center point and the second guide wheel 26.
[0019] The two first transmission plates 31 and the two second transmission plates 32 are distributed in a mirror image, and the two second transmission plates 32 are both "L"-shaped. The two first transmission plates 31 and the two second transmission plates 32 are distributed in a mirror image, and the outer surface of the support plate 40 is made of anti-slip material. The "L"-shaped second transmission plate 32 is for facilitating the clamping movement of the two second transmission plates through the second connecting shaft 33 by lifting the first connecting shaft 30. The outer surface of the support plate 40 is made of anti-slip material to prevent the support plate 40 from accidentally slipping out after internal support and fixation.
[0020] Working principle: when it is necessary to lift the building materials, the motor 20 is started, and the output end of the motor 20 drives the first capstan 28 and the second capstan 27 to rotate, and the cable 23 is rotated. When the first capstan 28 and the second capstan 27 rotate clockwise, the cable 23 on the surface of the first capstan 28 is wound through the first guide wheel 25 and the pulley 22, and the cable 23 on the surface of the second capstan 27 is released through the second guide wheel 26 and the pulley 22. Since there is a diameter difference between the second capstan 27 and the first capstan 28, the lifting plate 21 is driven to lift, and its lifting speed is related to the diameter difference between the second capstan 27 and the first capstan 28. The output end of the motor 20 rotates counterclockwise, and the cable 23 drives the lifting plate 21 to move downward through the second guide wheel 26, the first guide wheel 25 and the pulley 22, thereby achieving the purpose of lifting the building materials.
[0021] When it is necessary to hoist the building materials, the inner support device 3 is lowered by the lifting device 2, and the two support plates 40 are placed between the inner diameters of the building materials. The inner support device 3 is then lifted by the lifting device 2. The lifting force causes the two first transmission plates 31 to rise through the first connecting shaft 30. As the angle between the two rising first transmission plates 31 decreases, the two second transmission plates 32 are driven to move the bottom ends of the two second transmission plates 32 horizontally toward each other through the second connecting shaft 33. One of the sliding shafts 34 drives the second moving plate 37 to move horizontally to the right through the first through groove 36 in the first moving plate 35, and the other sliding shaft 34 drives the first moving plate 35 to move horizontally to the left through the second through groove 38 in the second moving plate 37, thereby fixing the building materials with the two support plates 40 through the inner support, so as to achieve the purpose of taking the building materials while lifting.
