Description

Technical Field

[0001] This utility model relates to hoisting machines, and more particularly to gypsum board hoisting machines. Background Technology

[0002] In the field of building decoration, the use of lifting platforms is crucial in the installation of gypsum board ceilings. For example, the patent application number 202111010935.4, entitled "A Heavy-Duty Gypsum Board Lifting Platform" (publication number: CN), provides this information.

[0003] The prior art disclosed in 113620203A has solved some problems to a certain extent, but still has many shortcomings.

[0004] Existing lifting tools generally only have one locking device. In actual use, if this locking device malfunctions, the plasterboard could suddenly fall, posing a serious threat to the lives of construction workers and creating a significant safety hazard. Furthermore, most existing lifting platforms do not employ gear transmission, resulting in difficulty in ensuring precision when controlling the lifting height, inconvenient vertical adjustment, and an inability to accurately meet the precise installation height requirements of plasterboard in different decoration scenarios. In addition, the support structure design of some existing lifting platforms is inadequate, making it difficult to retract effectively when not in use, and the relocation process is cumbersome, increasing construction time and labor costs and impacting construction efficiency. These problems limit the efficient application of plasterboard lifting platforms in the construction and decoration industry, urgently requiring new solutions for improvement. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a gypsum board hoisting machine.

[0006] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0007] The gypsum board hoisting machine includes a base frame with vertically arranged support pipes fixed on it. A lifting rod, which can be raised and lowered within the support pipes, is installed inside the support pipes. A support frame for placing the gypsum board is installed at the top of the lifting rod.

[0008] An outwardly extending mounting bracket is installed on the support pipe, and a rope winding mechanism is installed on the mounting bracket. A first pulley and a second pulley are installed at the upper and lower ends of the lifting rod, respectively. The first pulley is exposed outside the support pipe, and the second pulley is located inside the support pipe. A fixed pulley is installed inside the support pipe, and a rope is installed on the rope winding mechanism. The rope passes through the fixed pulley, the second pulley, and the first pulley in sequence before being fixed to the support pipe.

[0009] Preferably, the rope winding mechanism includes a base, a pinion, a gear, a drum, and a handle. The pinion is mounted on the base via a first pin, and the gear is also mounted on the base via a second pin. The pinion meshes with the gear. The drum is mounted on the second pin, and the other end of the rope is fastened to the drum. The handle is connected to the first pin.

[0010] Preferably, the side of the support tube is provided with a window, and the fixed pulley is mounted on the window through the first support. The rope passes through the window and then goes around the top of the fixed pulley.

[0011] Preferably, a second support is installed at the middle position of the support frame, the second support is hinged to the top of the lifting rod, and a latch for locking the second support is installed at the top of the lifting rod.

[0012] Preferably, an extension rod is fixed to one side of the support frame, and a handle is installed at the end of the extension rod.

[0013] Preferably, both ends of the other side of the support frame are fixed with blocks for blocking the plasterboard, and the blocks are perpendicular to the end face of the support frame.

[0014] Preferably, the mounting frame includes a mounting plate and two connecting rods, one end of which is fixed to the mounting plate and the other end of which is fixed to the support tube. The rope winding mechanism is fixed to the mounting plate.

[0015] Preferably, the base frame includes an upper fixing block, a lower fixing block, and at least three connecting rods. The upper fixing block and the lower fixing block are fixed on the support tube. All connecting rods are evenly distributed around the upper fixing block. The connecting rods are U-shaped, with one end of the connecting rod fixedly connected to the upper fixing block and the other end of the connecting rod fixedly connected to the lower fixing block.

[0016] Preferably, an operating platform is installed on two adjacent connecting rods, and the operating platform has a notch, which is adapted to the support tube.

[0017] Preferably, a caster wheel is installed at the outer end of the lower end of the connecting rod.

[0018] This utility model, by adopting the above technical solution, has significant technical effects:

[0019] By employing a design where ropes sequentially pass around a fixed pulley, a second pulley, and then a first pulley, a significant lifting height can be achieved in conjunction with the support pipe and lifting rod. Compared to some equipment with limited lifting height due to structural constraints, this rope-pulley combination better meets the needs of gypsum board ceilings in buildings with varying floor heights, offering strong construction adaptability.

[0020] Compared to rack and pinion lifting structures, the lifting system of this hoist, consisting of ropes, pulleys, and a rope winding mechanism, has a lower cost. Rack and pinion systems require high machining precision and have complex manufacturing processes, resulting in higher costs. In contrast, the rope and pulley structure of this hoist is simple, with relatively lower raw material and manufacturing costs, thus reducing the overall cost of the equipment.

[0021] This hoist has a lower failure rate. During long-term use, gear and rack systems are prone to tooth wear and breakage due to frequent meshing and friction; while rope and pulley systems have a relatively simple structure with fewer moving parts and less friction between components, reducing the probability of failure. Furthermore, the wear on ropes and pulleys is usually more uniform, making problems easier to detect.

[0022] Maintenance is much more convenient. If a gear and rack malfunctions, repair is difficult and may require specialized technicians and tools for disassembly, replacement, or repair. However, if the ropes of this hoisting machine wear out or break, replacement is relatively simple. Pulley maintenance mainly involves regular lubrication and inspection, which can be completed by ordinary construction workers after simple training. This significantly reduces maintenance and time costs and improves equipment efficiency. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-3 The present invention will be further described in detail with reference to the embodiments.

[0032] Example 1

[0033] The gypsum board hoisting machine includes a base frame 10, on which a vertically arranged support pipe 11 is fixed. The support pipe 11 is welded to the base frame 10. A lifting rod 12 that can be raised and lowered is installed inside the support pipe 11. A support frame 13 for placing gypsum boards is installed on the top of the lifting rod 12.

[0034] An outwardly extending mounting bracket 14 is installed on the support pipe 11, and a rope winding mechanism 15 is installed on the mounting bracket 14. A first pulley 16 and a second pulley 17 are respectively installed at the upper and lower ends of the lifting rod 12. The first pulley 16 protrudes outside the support pipe 11, while the second pulley 17 is located inside the support pipe 11. A fixed pulley 18 is installed inside the support pipe 11, near its upper end. A rope 19 is installed on the rope winding mechanism 15, and the rope 19 passes sequentially around the fixed pulley 18, the second pulley 17, and the first pulley 16 before being fixed to the support pipe 11. By controlling the winding and unwinding of the rope 19 through the rope winding mechanism 15, the lifting rod 12 can be easily raised and lowered, thereby causing the plasterboard on the support frame 13 to rise or fall. The operation is simple and easy to learn, reducing the difficulty of operation for construction personnel.

[0035] The rope winding mechanism 15 is activated to begin winding the rope. Under the action of the rope winding mechanism 15, the rope 19 is first pulled around the fixed pulley 18, which changes the direction of the rope 19's movement, causing it to move downwards. Next, the rope 19 passes over the second pulley 17 located inside the support tube 11. The second pulley 17, along with the movement of the rope 19, drives the lifting rod 12 upwards. When the rope 19 continues to move around the first pulley 16 exposed outside the support tube 11, it further provides tension for the lifting rod 12's ascent, ultimately raising the top support frame 13 of the lifting rod 12, thereby hoisting the plasterboard placed on the support frame 13 to the required height. When descent is required, the rope winding mechanism 15 releases the rope. Under the weight of the plasterboard, the rope 19 moves in the opposite direction, driving the lifting rod 12 and the support frame 13 downwards, completing the lowering operation of the plasterboard.

[0036] The rope winding mechanism 15 includes a base 151, a small gear 152, a large gear 153, a drum, and a handle 154. The drum is used to wind up the rope. The outer diameter of the large gear 153 is larger than that of the small gear 152. The small gear 152 is mounted on the base 151 via a first pin 155, and the large gear 153 is also mounted on the base 151 via a second pin 156. The small gear 152 meshes with the large gear 153. The drum is mounted on the second pin 156, and the other end of the rope 19 is fastened to the drum. The handle 154 is connected to the first pin 155. The transmission method using the meshing of the small gear 152 and the large gear 153, with the large gear 153 having a larger outer diameter than the small gear 152, applies the principle of a lever that saves effort. When the worker turns the handle 154 to drive the small gear 152, only a small force is needed to drive the large gear 153 to rotate, thereby driving the drum to wind up the rope 19, easily raising and lowering the lifting rod 12, improving work efficiency and reducing labor intensity.

[0037] The construction worker rotates the handle 154 connected to the first pin 155. The handle 154 drives the first pin 155 to rotate, which in turn causes the small gear 152 mounted on the first pin 155 to start rotating. Since the small gear 152 meshes with the large gear 153, the rotation of the small gear 152 will drive the large gear 153 to rotate. The large gear 153 is mounted on the machine base 151 via the second pin 156, and the drum is mounted on the second pin 156. Therefore, when the large gear 153 rotates, it will drive the drum to rotate synchronously. During the rotation of the drum, the rope 19 fastened to it is wound up or unwound. When the drum winds up the rope 19, the rope 19 pulls the lifting rod 12 upward, thereby driving the plasterboard on the support frame 13 to rise; when the drum unwinds the rope 19, under the action of the gravity of the plasterboard, the rope 19 moves in the opposite direction, driving the lifting rod 12 and the support frame 13 to descend.

[0038] The support pipe 11 has a window 111 on its side, through which the rope 19 passes. A fixed pulley 18 is mounted on the window 111 via a first support 20. After passing through the window, the rope 19 goes around the top of the fixed pulley 18. The window 111 on the side of the support pipe 11 provides a dedicated passage for the rope 19, making the transition of the rope 19 between the outside and inside of the support pipe 11 smoother, avoiding interference between the rope 19 and other parts of the support pipe 11, making reasonable use of the space of the support pipe 11, and making the entire hoisting machine structure more compact.

[0039] A second support 21 is installed in the middle of the support frame 13. The second support 21 is hinged to the top of the lifting rod 12. A latch for locking the second support 21 is installed at the top of the lifting rod 12. The support frame 13 can be set at an angle or horizontally on the top of the lifting rod 12. After the support frame 13 is positioned, it is locked to the top of the lifting rod 12 by the latch. The support frame 13 is hinged to the top of the lifting rod 12 via the second support 21 and can be set at an angle or horizontally. This allows for flexible adjustment of the angle of the support frame 13 according to the actual construction scenario when installing gypsum board. For example, when installing ceiling gypsum board with special angle requirements, the angled support frame 13 can better adapt to the installation position, improving the accuracy and convenience of construction. After the support frame 13 is adjusted to the appropriate position, it is locked to the top of the lifting rod 12 by the latch, effectively preventing the support frame 13 from accidentally rotating or shaking during hoisting. This locking mechanism enhances the stability of the overall structure, ensures the safety of the gypsum board during hoisting and installation, and avoids dangerous situations such as the gypsum board falling due to the instability of the support frame 13.

[0040] The second support 21 at the middle position of the support frame 13 is hinged to the top of the lifting rod 12, providing the support frame 13 with freedom of rotation. Construction workers manually adjust the angle of the support frame 13 according to construction needs, placing it in an inclined or horizontal position. Once the support frame 13 reaches the desired position, the second support 21 is securely locked using the latch installed at the top of the lifting rod 12. At this point, the support frame 13 and the lifting rod 12 form a stable integrated structure, capable of bearing the weight of the gypsum board and remaining stable during hoisting and installation, ensuring smooth construction.

[0041] An extension rod 22 is fixed to one side of the support frame 13. The extension rod 22 is welded to the support frame 13. A handle 23 is installed at the end of the extension rod 22. The handle 23 is welded to the extension rod 22. The handle 23 makes it convenient for construction personnel to adjust the tilt angle of the support frame 13.

[0042] Both ends of the other side of the support frame 13 are fixed with blocks 24 for blocking the plasterboard. The blocks 24 are perpendicular to the end face of the support frame 13. When the support frame 13 is tilted, the blocks 24 are used to support the plasterboard and prevent the plasterboard from falling off the support frame 13.

[0043] The mounting bracket 14 includes a mounting plate 141 and two connecting rods 142. One end of the connecting rod 142 is welded to the mounting plate 141, and the other end is welded to the support tube 11. The two connecting rods 142 are located at the upper and lower ends of the mounting plate 141. A rope winding mechanism 15 is located between the two connecting rods 142 and is fastened to the mounting plate 141 by screws.

[0044] The base frame 10 includes an upper fixing block 101, a lower fixing block 102, and at least three connecting rods 103. In this embodiment, there are four connecting rods 103. The upper fixing block 101 and the lower fixing block 102 are welded to the support pipe 11. All connecting rods 103 are evenly distributed around the upper fixing block 101. The connecting rods 103 are U-shaped, with one end fixedly connected to the upper fixing block 101 and the other end fixedly connected to the lower fixing block 102. The base frame 10 is welded to the support pipe 11 through the upper fixing block 101 and the lower fixing block 102, forming a stable connection. At least three evenly distributed U-shaped connecting rods 103 connect the upper and lower fixing blocks, providing support force to the support pipe 11 from multiple directions, effectively dispersing the force during equipment operation, reducing the swaying and deformation of the support pipe 11, and ensuring the stability of the hoist during the lifting of gypsum board.

[0045] The lower outer end of the connecting rod 103 is equipped with casters 26, which greatly enhances the mobility of the gypsum board hoisting machine. Construction workers can easily push the equipment, allowing it to turn and move freely around the construction site without requiring significant manpower for handling or the use of other auxiliary equipment to relocate it. Whether quickly switching between different construction areas or adjusting the equipment's position in confined spaces to align with the gypsum board installation points, the casters 26 enable the equipment to respond quickly and improve construction efficiency.

[0046] Example 2

[0047] Example 2 is basically the same as Example 1, except that an operating platform 25 is installed on each of the two adjacent connecting rods 103. The operating platform 25 provides a convenient place for workers to put tools, and workers can also stand on the operating platform 25 to place plasterboard onto the support frame 13. The operating platform 25 has a notch 251, which allows it to fit into the support tube 11. Installing the operating platform 25 on the two adjacent connecting rods 103 provides a dedicated platform for workers to place tools, preventing tools from being lost or inconvenient to access due to random placement. Workers do not need to frequently climb up and down the equipment to find tools, saving construction time and improving work efficiency. Workers can also stand on the operating platform 25 to directly place plasterboard onto the support frame 13, reducing the carrying distance and difficulty during construction, making the operation more convenient and efficient.
