[0020] The following further elaborates the present utility model in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the present utility model, those skilled in the art can make various changes or modifications to the present utility model, and these equivalent forms also fall within the scope defined by this application.

[0021] Refer to Figure 2, the utility model relates to a portable building material hoist. The main structure includes a base 1, which extends horizontally and serves as a support. A material platform 2 that moves up and down vertically is provided on the base 1, and the building materials to be lifted are placed on the material platform 2. A vertical support frame 3 is movably connected to the base 1, and the bottom of the support frame 3 is fixed to the base 1 by any existing detachable means, such as bolt connection or movable insertion. A sliding frame 4 is fixedly welded or integrally formed on one side of the material platform 2, and the sliding frame 4 is slidably connected to the support frame 3 vertically. Such a structure can drive the material platform 2 to move up and down vertically when the sliding frame 4 slides up and down along the support frame 3, so as to realize the lifting operation of the building materials on the material platform 2. A wire roller 5 and a lifting motor 6 for driving the wire roller 5 to rotate are provided on the base 1. Specifically, the wire roller 5 is rotatably connected to the base 1 through a bearing, and the output shaft of the lifting motor 6 is connected to the wire roller 5 to drive the rotation of the wire roller 5. A rope 7 is wound around the wire roller 5. The rope 7 generally uses a steel wire rope to ensure sufficient load-bearing strength. Specifically, one end of the rope 7 is bolted or tied to the wire roller 5 and then wound along the circumference of the wire roller 5. The top of the support frame 3 is rotatably connected to a steering wheel 8 through a bearing. One end of the rope 7 bypasses the top of the steering wheel 8 and is movably connected to the sliding frame 4. Such a structure can make the rope 7 contract and continue to wind on the wire roller 5 when the lifting motor 6 drives the wire roller 5 to rotate, so that the sliding frame 4 at one end of the rope 7 rises along the support frame 3, thus realizing the lifting drive of the sliding frame 4 and the material platform 2. The structure is simple, the operation is convenient, and the application scenarios are more diverse. After use, the support frame 3 can be removed from the base 1, and at the same time, the connection between the rope 7 and the sliding frame 4 is released, so that the floor area of each part after disassembly is smaller, which is more convenient for transportation. The assembly steps during re-use are also simpler, thereby improving the convenience of transportation and use. Especially for the lifting of building materials with relatively low weight, the convenience of use is greatly improved, the application scenarios are more diverse, and the lifting of building materials is more convenient and efficient.

[0022] Preferably, referring to Figure 1 , a hopper 9 is slidably connected to the material platform 2 horizontally. One end of the hopper 9 slides outside the material platform 2 and then rotates relative to the material platform 2. Such a structure can ensure the stable contact between the hopper 9 and the material platform 2 when the materials are lifted vertically, ensuring the stability of the materials during the lifting process. After lifting to a high place, the hopper 9 is slid horizontally so that one end of it slides outside the material platform 2 and then the hopper 9 is rotated, enabling the materials in the hopper 9 to be unloaded along one end of the inclined hopper 9, making the unloading of the materials more convenient and efficient.

[0023] Preferably, referring to Figure 4, on both sides of the material platform 2, there are symmetrically arranged limiting grooves 10. The limiting grooves 10 are groove-shaped structures composed of steel pipes or steel plates, and are fixed on both sides of the top of the material platform 2 by welding or bolts. On both sides of the hopper 9, there are symmetrically arranged turnover shafts 11 rotatably connected by bearings. The turnover shafts 11 are slidably connected in the limiting grooves 10. Such a structure enables the hopper 9 to slide and rotate horizontally relative to the material platform 2 through the turnover shafts 11. After the turnover shafts 11 slide from the inner end of the limiting grooves 10 to the outer end, the end of the hopper 9 loses its restriction and can rotate relative to the limiting grooves 10, thereby realizing the unloading of the materials on the hopper 9. The structure is simple and convenient to use. On the side of the hopper 9, there is a positioning column 12 used in cooperation with the limiting groove 10. Specifically, the positioning column 12 is threadedly connected to the side of the hopper 9. When the turnover shaft 11 is located at the inner end of the limiting groove 10, the positioning column 12 passes through the outer end and is threadedly fixed to the side of the hopper 9, thereby realizing the relative fixation of the positions of the hopper 9 and the limiting groove 10, avoiding the movement of the hopper 9 relative to the material platform 2 during the lifting process, and further ensuring the safety of the materials during the lifting process.

[0024] Preferably, referring to Figure 3 , on the base 1, there is a fixed sleeve 13 fixed by welding or bolts. The bottom of the support frame 3 is movably inserted into the fixed sleeve 13, making the disassembly and assembly cooperation between the support frame 3 and the fixed sleeve 13 more efficient and convenient. Specifically, the support frame 3 is composed of two columns and a cross beam. Multiple cross beams are fixed between the two columns by welding or bolts. The bottom of the column is movably inserted into the fixed sleeve 13, making the overall structure of the support frame 3 more stable and with stronger load-bearing capacity. Between the top of the support frame 3 and the base 1, there is a reinforcing diagonal rod 14 movably connected. Specifically, both ends of the reinforcing diagonal rod 14 are movably connected to the top of the support frame 3 and the base 1 by bolts, making the overall structure of the support frame 3 more stable and more convenient and efficient to disassemble.

[0025] Preferably, on the sliding frame 4, there is a hanging ring 15 fixed by welding or bolts. At the end of the rope 7, there is a hook 16 used in cooperation with the hanging ring 15. The hook 16 is hung in the hanging ring 15, making the disassembly and assembly cooperation between the rope 7 and the sliding frame 4 more flexible and convenient. At the bottom of the sliding frame 4, there is a lifting pulley 17 in rolling contact with the support frame 3. The sliding frame 4 moves up and down along the support frame 3, and the lifting roller is in rolling contact with the support frame 3, making the sliding resistance of the sliding frame 4 smaller and making the lifting of the materials smoother.

[0026] Preferably, a plurality of moving wheels 18 are provided at the bottom of the base 1. Specifically, universal wheels can be used, enabling the device to be conveniently pushed to the position where it needs to be lifted and used. A plurality of support columns 19 are symmetrically and threadedly connected to both sides of the base 1. Specifically, fixing plates are symmetrically arranged on both sides of the base 1. The support columns 19 penetrate through the fixing plates and are threadedly connected thereto. By rotating the support columns 19, the length of the support columns 19 located at the bottom of the fixing plates can be changed. Thus, when it is necessary to move, rotate the support columns 19 in the reverse direction so that the device can move quickly under the action of the moving wheels 18, ensuring the convenience of the overall movement of the device and the firmness of its use.

[0027] Working principle: The structure of the present utility model is provided with a support frame 3 and a wire roller 5 on the base 1. A steering wheel 8 is arranged at the top of the support frame 3. A sliding frame 4 is slidably arranged on the support frame 3. A material table 2 is arranged on the sliding frame 4. The rope 7 on the wire roller 5 bypasses the steering wheel 8 and is connected to the sliding frame 4. When lifting materials, the lifting motor 6 drives the wire roller 5 to rotate, causing the rope 7 to contract. Thus, the sliding frame 4 and the material table 2 at one end of the rope 7 can slide upward along the support frame 3, thereby realizing the lifting operation of the building materials on the material table 2. The structure is simple, the assembly is convenient, the application scenarios are more abundant, and the use is more flexible. The lifting efficiency of building materials with relatively low weight is further improved; the bottom of the support frame 3 is movably connected to the base 1, and the end of the rope 7 is movably connected to the sliding frame 4. Such a structure can remove the support frame 3 from the base 1 when the use is completed, and disconnect the connection between the rope 7 and the sliding frame 4. Thus, the floor area occupied by each part after disassembly is greatly reduced, facilitating the overall transportation. At the same time, the assembly steps during re-use are also more simplified, making the disassembly and assembly operations of the entire device more convenient and efficient, and further improving the convenience of use and transportation.
