[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0024] See Figures 1-4 As shown, this utility model provides a hoisting device for building materials, including a base plate 1. The upper surface of the base plate 1 is provided with a movable base plate 2 that can move along its long side. Two support plates 3 are fixedly connected to one side of the upper surface of the movable base plate 2. A rotating shaft 301 is rotatably connected between the two support plates 3. The rotating shaft 301 is provided with two adjustable take-up wheels 302 that rotate with it. The upper surface of the movable base plate 2 is provided with two extension arms 4, and the two extension arms 4 correspond one-to-one with the two take-up wheels 302. The upper end of each of the two extension arms 4 is provided with a guide wheel structure. The surface of each of the two take-up wheels 302 is fixedly connected to and wound with a connecting rope 304. The other end of the connecting rope 304 passes over the upper side of the guide wheel structure and is fixedly connected to a hook 13. The lower end of the extension arm 4 is provided with a rotating connecting frame for driving the take-up wheel 302 to move. The surface of the movable base plate 2 is provided with bolted connectors 5 for fixing the position of the extension arms 4.
[0025] As an optional implementation, T-shaped grooves 7 are provided on both sides of the surface of the base plate 1, and T-shaped slide bars 8 that are slidably connected to the T-shaped grooves 7 are fixedly connected to both sides of the bottom surface of the movable base plate 2. The surface of the base plate 1 is provided with a plug-in component 6 for fixing the position of the movable base plate 2, which can make the movable base plate 2 more stable when moving and prevent it from separating from the base plate 1.
[0026] Reference Figure 3 As shown, the plug-in assembly 6 includes a protruding plate 601 fixedly connected to the middle of the movable base plate 2. A through hole 602 is provided through the protruding plate 601, and a pin 603 is inserted into the through hole 602. Several positioning holes 604 are provided on the surface of the base plate 1 for inserting the pin 603. A magnetic plate 605 is fixedly connected to the end of the pin 603, and the magnetic plate 605 is magnetically connected to the iron protruding plate 601. When the movable base plate 2 moves to a suitable position, the pin 603 is inserted into the through hole 602 and the positioning hole 604 at the same time, which can complete the position fixation of the movable base plate 2. At this time, the two hooks 13 will move away to a suitable position on the outer surface of the building, which not only ensures the smooth rise of the building materials, but also ensures the stability during the rise. At the same time, the magnetic plate 605 can prevent the pin 603 from falling off through magnetic force.
[0027] Reference Figure 2 As shown, the middle part of the take-up reel 302 is sleeved on the rotating shaft 301 through the sliding hole 303. The cross-section of both the sliding hole 303 and the rotating shaft 301 is regular hexagonal. A motor 305 for driving the rotating shaft 301 to rotate is fixedly installed on one of the support plates 3. When the rotating shaft 301 rotates with the motor 305, it can smoothly drive the two take-up reels 302 to rotate due to the edge limit. At the same time, the take-up reels 302 can move their positions on the rotating shaft 301 through the sliding hole 303.
[0028] Reference Figure 4 As shown, the guide wheel structure includes a guide wheel seat 10 fixedly connected to the upper end of the extension support arm 4. A guide wheel 11 is rotatably connected in the guide wheel seat 10, and the connecting rope 304 passes over the upper side of the guide wheel 11. An anti-detachment ring 12 is fixedly connected to the upper side of the guide wheel seat 10 to prevent the connecting rope 304 from falling off. By passing the connecting rope 304 over the upper side of the guide wheel 11, the connecting rope 304 is located between the anti-detachment ring 12 and the guide wheel 11, which can prevent the connecting rope 304 from accidentally falling off.
[0029] Reference Figure 2As shown, the rotating connecting frame includes a C-shaped frame 401 fixedly connected to the end of the extension arm 4. Both ends of the C-shaped frame 401 are fixedly connected to connecting rings 402, and both ends of the take-up reel 302 are fixedly connected to fixing rings 403. The connecting rings 402 are rotatably connected to the fixing rings 403 through bearings. By rotatably connecting the connecting rings 402 and the fixing rings 403, it can be ensured that the take-up reel 302 is always located directly behind the extension arm 4, and the take-up reel 302 can rotate smoothly with the rotating shaft 301.
[0030] Reference Figure 2 and 4 As shown, both sides of the bottom surface of the extension arm 4 are rotatably connected to rollers 9 that abut against the surface of the movable base plate 2. The bolt connector 5 includes a sleeve 501 fixedly connected to the lower end of the side wall of the extension arm 4. A bolt 502 is inserted into the sleeve 501. Several bolt holes 503 connected to the bolts 502 are opened on the surface of the movable base plate 2. The rollers 9 can make the extension arm 4 move more smoothly and stably on the surface of the movable base plate 2. When the extension arm 4 moves to a suitable position, the bolts 502 are inserted into the sleeve 501 and the bolt holes 503 at the same time for rotation, thereby fixing the position of the extension arm 4 and the take-up reel 302.
[0031] First, the base plate 1 is fixed to the top of the building construction project with expansion bolts and connected to the mains power. The movable base plate 2 is adjusted according to the size and length of the building materials to be lifted, so that it moves outward from the surface of the base plate 1, so that the two hooks 13 are away from the outer surface of the building. Then, the two extension arms 4 are moved (due to the existence of the rotating connecting frame, it can be ensured that the take-up reel 302 is always located directly behind the extension arm 4), so that the two hooks 13 are moved away from each other to a suitable lifting distance and hung on both sides of the building material hoisting basket. The rotation of the rotating shaft 301 can drive the two take-up reels 302 to simultaneously wind up the connecting rope 304, thereby driving the hoisting basket to rise and lift.
[0032] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
