DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] See also Figures 1 to 4The utility model provides a technical solution: a building material lifting device, including a mobile base 1, a slide groove 2 is provided inside the mobile base 1, a support plate 3 is slidably connected inside the slide groove 2, the top of the support plate 3 is rotatably connected to the bottom plate 4, a support frame 5 is installed on the top of the bottom plate 4, a first guide wheel 6 is installed on the top of the support frame 5, a groove 8 is provided inside the support frame 5, a second guide wheel 9 is rotatably connected inside the groove 8, a frame 10 is installed on the top of the bottom plate 4 and on one side of the support frame 5, a reel 11 is rotatably connected inside the frame 10, a steel wire rope 12 is wound around the outside of the shaft of the reel 11, one end of the steel wire rope 12 is bypassed around the second guide wheel 9 and the first guide wheel 6 to install a weight sensor 13, and the sensing end of the weight sensor 13 is connected to A fixing rope 14 is provided, one end of which is connected to a carrier frame 15. The structure of the carrier frame 15 is concave, which is convenient for placing materials. A first motor 16 is installed on one side of the frame 10. The output end of the first motor 16 is fixedly connected to the reel 11, providing power for the rotation of the reel 11, controlling the retraction and release of the wire rope 12, and the carrier frame 15 rises and falls accordingly, which is convenient for lifting and conveying materials. A convex limiting groove 17 is provided inside the support frame 5 and at the bottom of the groove 8. A convex limiting block 18 is slidably connected inside the convex limiting groove 17. One side of the convex limiting block 18 is fixedly connected to a limiting frame 19. One end of the limiting frame 19 is connected to the carrier frame 15 to limit the carrier frame 15 so that it will not shake when it is lifted or lowered. A magnetic metal layer 20 is installed on the convex limit block 18, a cavity 7 is opened inside the convex limit block 18, an electric telescopic rod 21 is installed inside the cavity 7, and a magnet sheet 22 is fixedly connected to the output end of the electric telescopic rod 21, so that the magnet sheet 22 can be displaced as the electric telescopic rod 21 moves according to needs, and fits and adsorbs with the magnetic metal layer 20, thereby increasing the friction between the convex limit block 18 and the magnetic metal layer 20, and reducing the falling speed of the convex limit block 18 and the carrier frame 15. An alarm 28 is installed on one side of the support frame 5, and the weight sensor 13 is electrically connected to the electric telescopic rod 21 and the alarm 28 respectively, so as to weigh the carrier frame 15 and the material, so as to trigger the electric wire rope 12 or the fixed rope 14 in time when the wire rope 12 or the fixed rope 14 breaks. The telescopic rod 21 and the alarm 28 are in operation to reduce the falling speed of the carrier 15, avoid accidents, and remind the surroundings. A damper 27 is installed at the bottom of the carrier 15, and a buffer plate 26 is connected to the bottom of the damper 27. Two shock-absorbing springs 25 are installed between the carrier 15 and the buffer plate 26 and on both sides corresponding to the damper 27. Through the deformation of the shock-absorbing springs 25, in cooperation with the damper 27, the carrier 15 can be shock-absorbing and buffered to avoid collision with the mobile base 1 or the support plate 3 when the carrier 15 descends. A guide shaft 23 is installed inside the slide 2, and the guide shaft 23 passes through the support plate 3. A locking bolt 30 is threadedly connected to the inside of the support plate 3 and located on one side of the bottom plate 4, and is connected to the slide 2 through the sliding connection of the support plate 3.The support plate 3 can slide on the slide groove 2 and be fixed by rotating the locking bolt 30 to adjust the position of the support plate 3, the support frame 5 and the carrier frame 15. The second motor 24 is fixedly installed inside the support plate 3. The output end of the second motor 24 is fixedly connected to the bottom plate 4 to drive the bottom plate 4 to rotate, which is convenient for adjusting the angle of the support frame 5 and the carrier frame 15. A control panel 29 is installed on one side of the support frame 5 and at the bottom of the alarm 28. The control panel 29 is electrically connected to the first motor 16 and the second motor 24 respectively, which is convenient for controlling the operation of the first motor 16 and the second motor 24.

[0022] In summary, when the building material lifting device is used, after the material is placed on the load-bearing frame 15, the first motor 16 drives the reel 11 to rotate, and the steel wire rope 12 is wound, so that the weight sensor 13 and the fixed rope 14 at one end of the steel wire rope 12 pull the load-bearing frame 15 and the material to lift. While the material is being transported, since a convex limit block 18 slides in the convex limit groove 17 in the support frame 5, and the limit frame 19 on one side of the convex limit block 18 is connected to the load-bearing frame 15, the convex limit block 18 is raised and lowered as the limit frame 19 is lifted, and the load-bearing frame 15 is limited. At the same time, the weight sensor 13 weighs the load-bearing frame 15. When the steel wire rope 12 and the fixed rope 14 are broken, the load-bearing frame 15 suddenly falls, and the convex limit block 18 moves down with the load-bearing frame 15. The weight sensor 13 weighs the load-bearing frame 15 according to the weight. The change automatically triggers the operation of the electric telescopic rod 21 in the convex limiting block 18, causing the magnet sheet 22 at its output end to move, fit and absorb with the magnetic metal layer 20 in the convex limiting groove 17, increase the friction between the convex limiting block 18 and the convex limiting groove 17, reduce the descending speed of the support frame 15, and start the alarm 28 to remind the surroundings. When the position or angle of the support frame 15 needs to be adjusted, the support plate 3 under the support frame 5 can be slid to move it in the movable base 1. The guide shaft 23 penetrates the support plate 3, and the locking bolt 30 in the support plate 3 is rotated to displace one end of it and press the guide shaft 23, so that the position of the support plate 3 and the support frame 5 can be fixed. Since the bottom plate 4 is rotatably connected to the support plate 3, the second motor 24 drives the bottom plate 4 to rotate, so that the angle of the support frame 5 and the support frame 15 can be adjusted.

[0023] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
