Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and particularly relates to a material hoisting platform for building construction. Background Art

[0002] In modern building construction, the rapid progress of multi-story and high-rise projects has put forward higher requirements for the vertical transportation of construction materials. Traditional material hoisting platforms usually use methods such as winding ropes or hydraulics to achieve the lifting and lowering of materials. However, in actual applications, there are problems such as the lifting ropes being easily interfered by external factors, insufficient protection of the movable doors, and defects in operation and safety control. In traditional platforms, the lifting ropes are often exposed to the external environment and are prone to entanglement, wear, or damage due to dust, debris, or external force interference, resulting in unstable operation of the platform or even causing safety accidents. At the same time, during the lifting or lowering of materials, if the movable doors on the platform are not effectively locked, they may accidentally open due to vibration or accidental touch, thus increasing the risk of materials falling from a height. Summary of the Invention

[0003] The purpose of the present invention is to solve the disadvantages existing in the prior art, and to propose a material hoisting platform for building construction.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A material hoisting platform for building construction includes a base. A fixed column and a hoisting platform are arranged at the top of the base. A movable door is movably arranged on one side of the hoisting platform. The fixed column includes two first columns and two second columns distributed in a rectangle. Through holes one are opened on the sides of the first columns and the second columns. Extension components are arranged at the four corners of the hoisting platform. One end of the extension component extending through the through hole one into the first columns and the second columns is connected with a lifting rope. At the top of the first columns and the second columns, a horizontally arranged fixed rod is installed through a mounting frame. A winding shaft is movably installed inside the base. One end of the lifting rope far from the extension component is wound around the winding shaft. The lifting rope is folded around the fixed rod and arranged inside the first columns and the second columns. A driving motor and a controller are arranged on the base. Through holes two are opened on the opposite sides of the two first columns. A number of spaced protective baffles are movably installed inside the through holes two. A magnetic component is arranged at one end of the protective baffle. An electromagnetic component is arranged at the position of the lifting rope close to the movable door. The position of the electromagnetic component corresponds to the position of the magnetic component.

[0006] Preferably, a groove is opened on the side of the extension component.

[0007] Preferably, a clamping mechanism is arranged inside the hoisting platform for clamping and fixing the materials inside the hoisting platform.

[0008] Preferably, the clamping mechanism includes a first telescopic member installed on the inner wall of the lifting platform, and one end of the piston rod of the first telescopic member is installed with a clamping mesh plate.

[0009] Preferably, an installation cavity is formed at the bottom of the lifting platform, and through holes three are formed at intervals at the top of the installation cavity. An auxiliary mechanism is arranged in the installation cavity for assisting in feeding or discharging materials into or from the lifting platform.

[0010] Preferably, the auxiliary mechanism includes a fixed seat installed at the bottom of the lifting platform. A second telescopic member is installed on the fixed seat, and one end of the piston rod of the second telescopic member extending into the installation cavity is installed with a mounting seat. A number of movable rollers are movably installed on the mounting seat at intervals, and the positions of the movable rollers correspond to the opening positions of the through holes three.

[0011] Preferably, a limiting member is arranged on the outer wall of the lifting platform. The limiting members are arranged at intervals along the circumferential direction of the lifting platform. Two adjacent limiting members are respectively located on the sides of the first column and the second column, and form a stable limiting cooperation structure with the first column and the second column.

[0012] Preferably, a positioning port is formed at the top of the base, and the opening position of the positioning port corresponds to the position of the fixed seat.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. Improve stability and safety: By arranging a limiting member on the outer wall of the lifting platform to form a stable limiting structure with the first column and the second column, it effectively prevents the horizontal offset of the platform during the lifting process due to lateral wind force or accidental impact, and improves the stability and safety of the equipment operation. At the same time, the limiting member can adopt a roller guiding structure or an elastic buffer mechanism to reduce the frictional resistance and enhance the impact resistance ability, ensuring that the platform can still operate stably in a harsh environment.

[0015] 2. Efficient material feeding and discharging functions: The auxiliary mechanism is adopted to optimize the material feeding and discharging processes. Among them, the movable rollers in the installation cavity drive the mounting seat to lift through the second telescopic member, so that the movable rollers extend into the interior of the lifting platform through the through holes three, effectively reducing the friction between the bottom of the material and the platform when pulling the material, improving the material fluidity, reducing the difficulty of manual operation, and improving the operation efficiency.

[0016] 3. Precise positioning to ensure stable operation: Through the cooperation of the positioning port at the top of the base and the fixed seat, the lifting platform can be precisely positioned when it descends to the top of the base, ensuring that the platform will not shake or be misaligned during feeding or discharging. At the same time, the fitting relationship between the positioning port and the fixed seat can be used to detect whether the platform is offset. Combined with sensors or mechanical detection devices, the docking situation of the platform can be monitored in real time, improving the intelligent level of the equipment.

[0017] 4. The clamping mechanism enhances the fixing effect of the material: A clamping mechanism is provided inside the lifting platform, which includes a horizontally movable clamping mesh plate. The clamping force is driven and adjusted by the first telescopic component, which can adapt to materials of different sizes and shapes, ensuring that the material does not slip or tip during lifting and improving transportation safety. At the same time, the clamping mesh plate adopts a grid structure to reduce wind resistance and the surface pressure of the material, improving applicability.

[0018] 5. Structural optimization for smooth operation: By optimizing the arrangement of the lifting ropes, they bypass the fixed rod and pass through the groove on the side of the extension component, enhancing the guiding stability of the lifting ropes, preventing the ropes from shifting or knotting, ensuring a smooth lifting process, reducing vibrations and impacts during operation, and extending the service life.

[0019] 6. Intelligent adaptation and strong adaptability: The lifting platform can achieve the linkage of the limit, clamping, and auxiliary mechanisms through an automated control system, ensuring the accuracy and safety of material transportation. The movable rollers of the auxiliary mechanism can be adaptively adjusted according to the sizes and shapes of different materials, and the clamping mechanism can also adjust the clamping force according to the material characteristics, making it applicable to a variety of construction scenarios and improving construction efficiency and equipment adaptability.

Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0030] In one embodiment, referring to Figures 1 to 8 , a material hoisting platform for building construction includes a base 1. A fixing column 25 and a hoisting platform 4 are provided on the top of the base 1. A movable door 3 is movably arranged on one side of the hoisting platform 4. The fixing column 25 includes two first columns 5 and two second columns 24 distributed in a rectangle. First through holes 7 are opened on the sides of the first column 5 and the second column 24. Extension components 13 are arranged at the four corners of the hoisting platform 4. One end of the extension component 13 extending into the first column 5 and the second column 24 through the first through hole 7 is connected to a hoisting rope 10. The tops of the first column 5 and the second column 24 are installed with a horizontally arranged fixing rod 9 through a mounting frame 8. A winding shaft 16 is movably installed inside the base 1. One end of the hoisting rope 10 away from the extension component 13 is wound around the winding shaft 16. The hoisting rope 10 is folded around the fixing rod 9 and arranged inside the first column 5 and the second column 24. A driving motor 15 and a controller 23 are arranged on the base 1. Second through holes 19 are opened on the opposite sides of the two first columns 5. A plurality of protective baffles 6 arranged at intervals are movably installed inside the second through holes 19. A magnetic component 20 is arranged at one end of the protective baffle 6. An electromagnetic component 12 is arranged at a position of the hoisting rope 10 close to the movable door 3. The position of the electromagnetic component 12 corresponds to the position of the magnetic component 20.

[0031] First, load the construction materials to be lifted onto the lifting platform 4, and close the movable door 3 provided on one side of the lifting platform 4; subsequently, drive the winding shaft 16 inside the base 1 to rotate through the driving motor 15, so that the lifting rope 10 at the end far from the extension member 13 is evenly wound. The lifting rope 10 passes through the guide of the fixed rod 9 and is arranged in a folded manner inside the first column 5 and the second column 24, and is connected to the extension member 13, thereby driving the synchronous ascent of the lifting platform 4 to complete the lifting of the materials. At the same time, since the lifting rope 10 is hidden inside the column, the winding and damage caused by exposure are avoided; when it is necessary to lower the lifting platform 4, the driving motor 15 rotates in the reverse direction to unwind the winding shaft 16, and the lifting platform 4 descends smoothly under its own gravity, facilitating the lowering of the materials; during the lifting and lowering process of the lifting platform 4, the controller 23 turns on the power supply of the electromagnetic component 12 through the switch, so that the electromagnetic component 12 located near the movable door 3 generates a magnetic repulsive force with the magnetic component 20 at the corresponding position, thereby promoting the protective baffle 6 arranged on the first column 5 at intervals through the second through hole 19 to rotate away from the electromagnetic component 12 to the horizontal state, locking and limiting the movable door 3 to prevent the accidental opening of the movable door 3 during the lifting and lowering process, resulting in the falling off of the materials; when the lifting platform 4 and the electromagnetic component 12 continue to move so that the protective baffle 6 is displaced from the electromagnetic component 12, the protective baffle 6 automatically rotates downward and resets to maintain a vertical setting under the action of gravity, ensuring that the movable door 3 can be effectively limited in a timely manner at different heights; when loading or unloading is required, the controller 23 disconnects the power supply of the electromagnetic component 12, so that the protective baffle 6 returns to the vertical state under the action of gravity, releasing the lock on the movable door 3, thereby facilitating the opening of the movable door 3.

[0032] As a preferred embodiment of the present invention, the movable door 3 is provided with a locking mechanism, which can adopt a mechanical lock or an electromagnetic lock structure to ensure that the movable door 3 remains closed when it does not reach the specified position or the unlocking operation is not performed, preventing safety risks caused by the accidental slipping of materials or the misoperation of personnel.

[0033] As a preferred embodiment of the present invention, a groove 17 is formed on the side surface of the extension member 13. One end of the lifting rope 10 far from the extension member 13 passes around the fixed rod 9 and then penetrates and is arranged in the groove 17. The groove 17 stably guides the lifting rope 10 to ensure the running stability and force balance of the lifting rope 10.

[0034] As a preferred embodiment of the present invention, a clamping mechanism 11 is arranged inside the lifting platform 4 for clamping and fixing the materials inside the lifting platform 4.

[0035] As a preferred embodiment of the present invention, the clamping mechanism 11 includes a first telescopic member 112 installed on the inner wall of the lifting platform 4. The first telescopic member 112 is in the form of a hydraulic cylinder or an electric push rod to provide stable and controllable driving force. One end of the piston rod of the first telescopic member 112 is connected to the clamping mesh plate 111. The clamping mesh plate 111 is made of high-strength material and has a grid-like structure to reduce wind resistance and uneven force on the surface of the material. The first telescopic member 112 can drive the clamping mesh plate 111 to move horizontally to clamp and fix the material in the lifting platform 4.

[0036] The control system of the clamping mechanism 11 can be linked with the lifting system of the lifting platform 4. Before the platform starts to lift or lower, it automatically adjusts the clamping force of the first telescopic member 112 to make the clamping mesh plate 111 closely adhere to the surface of the material, achieving stable clamping and preventing the material from sliding or tilting due to inertia. The mesh size of the clamping mesh plate 111 can be optimized according to the characteristics of different materials to avoid exerting excessive pressure on the material while ensuring stability, thereby improving the stability and applicability of the equipment.

[0037] As a preferred embodiment of the present invention, an installation cavity 22 is opened at the bottom of the lifting platform 4. Through holes three 21 are opened at intervals at the top of the installation cavity 22. An auxiliary mechanism 18 is arranged in the installation cavity 22 to assist in loading or unloading the material into or from the lifting platform 4.

[0038] As a preferred embodiment of the present invention, the auxiliary mechanism 18 includes a fixed seat 183 installed at the bottom of the lifting platform 4. A second telescopic member 184 is installed on the fixed seat 183. The second telescopic member 184 is in the structure of an electric push rod, a cylinder or a hydraulic cylinder to provide stable lifting power. One end of the piston rod of the second telescopic member 184 extends into the installation cavity 22 and is connected to the mounting seat 182. The mounting seat 182 is made of high-strength material to ensure the bearing capacity and stability.

[0039] A number of spaced-apart movable rollers 181 are movably installed on the mounting seat 182. The movable rollers 181 are made of low-friction material and are supported by bearings to reduce the rotational resistance. The arrangement position of the movable rollers 181 corresponds to the through holes three 21 to ensure that the movable rollers 181 can smoothly extend into the interior of the lifting platform 4 when the auxiliary mechanism 18 is activated.

[0040] When performing the loading or unloading operation, the second telescopic member 184 drives the mounting seat 182 to move upward, so that the movable rollers 181 extend into the interior of the lifting platform 4 through the through holes three 21 and contact the bottom of the material. When it is necessary to move the material, the movable rollers 181 can effectively reduce the friction between the material and the lifting platform 4, enabling the material to slide smoothly under a small driving force and improving the efficiency of loading or unloading.

[0041] In addition, the movable roller 181 can be adaptively adjusted through an elastic connection structure or an independent angle adjustment mechanism to adapt to materials of different sizes and shapes, ensuring a stable auxiliary function under various working conditions. At the same time, the structure of the mounting seat 182 can be optimized according to the load requirements to provide reliable support under different material weight conditions, further improving the adaptability and operation stability of the equipment.

[0042] As a preferred embodiment of the present invention, a limiting component 14 is provided on the outer wall of the lifting platform 4. The limiting components 14 are arranged at intervals along the circumferential direction of the lifting platform 4. Two adjacent limiting components 14 are respectively located on the sides of the first column 5 and the second column 24, and form a stable limiting cooperation structure with the first column 5 and the second column 24. The limiting component 14 is made of wear-resistant and impact-resistant materials and is connected to the lifting platform 4 through a shock-absorbing cushion layer or an elastic buffer structure to further enhance the impact resistance and improve the durability.

[0043] During the lifting and lowering process of the lifting platform 4, the limiting component 14 restricts its displacement in the horizontal direction by fitting with the first column 5 and the second column 24, preventing horizontal offset caused by factors such as lateral wind force, accidental impact or eccentric load, and ensuring that the lifting platform 4 operates stably along the predetermined trajectory. The structure of the limiting component 14 can include a roller guiding mechanism, so that when it contacts the first column 5 and the second column 24, the friction resistance can be reduced through the rotation of the rollers, improving the smoothness of the overall operation.

[0044] In addition, the limiting component 14 can be equipped with a dynamic adjustment mechanism, enabling it to automatically adjust the gap between the first column 5 and the second column 24 according to different working states to adapt to the limiting requirements under different load conditions, thereby further improving the safety and reliability of the equipment.

[0045] As a preferred embodiment of the present invention, a positioning port 2 is opened at the top of the base 1. The opening position of the positioning port 2 corresponds to the position of the fixed seat 183 and is precisely matched according to the size and shape of the fixed seat 183, so as to ensure that when the lifting platform 4 descends to the top of the base 1, the fixed seat 183 can smoothly embed into the positioning port 2 to achieve precise positioning. A buffer pad is provided on the inner wall of the positioning port 2 to reduce the impact when the fixed seat 183 is inserted and improve the durability of the positioning structure.

[0046] When the lifting platform 4 descends to the base 1 and completes the docking, the fixed seat 183 is inserted into the positioning port 2. Through the stable positioning of the fixed seat 183, it is ensured that the lifting platform 4 remains horizontally stable during the loading and unloading processes, preventing uneven accumulation or slipping of materials due to platform shaking or offset. The positioning port 2 can adopt a conical guiding structure to gradually guide the fixed seat 183 into it even in the case of a slight offset of the platform, improving the docking accuracy.

[0047] In addition, the limit structure can also be part of the position monitoring of the lifting platform 4. By using sensors or mechanical limits, it can detect whether the fixed seat 183 is accurately inserted into the positioning port 2, so as to determine whether the lifting platform 4 is offset. If the fixed seat 183 fails to be correctly snapped into the positioning port 2, the system can issue an alarm or automatically adjust the horizontal position of the lifting platform 4 to ensure the stable positioning of the platform on the base 1 and improve the safety and reliability of the overall operation.

[0048] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
