Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a material lifting platform for building construction. Background Art

[0002] In modern construction, the rapid advancement of multi-story and high-rise projects has put forward higher requirements for the vertical transportation of construction materials. Traditional material lifting platforms usually use rope winding or hydraulic methods to achieve material lifting and lowering. However, in actual applications, there are problems such as the lifting rope is easily disturbed by external factors, the movable door is not adequately protected, and there are defects in operation and safety control. In traditional platforms, the lifting rope is often exposed to the external environment and is easily entangled, worn or damaged due to dust, debris or external interference, resulting in unstable platform operation and even safety accidents; at the same time, during the lifting or lowering of materials, if the movable door on the platform fails to be effectively locked, it may be accidentally opened due to vibration or accidental touch, thereby increasing the risk of materials falling from high altitudes. Summary of the invention

[0003] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a material lifting platform for construction.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions: A material lifting platform for construction, comprising a base, a fixed column and a lifting platform are arranged on the top of the base, a movable door is movably arranged on one side of the lifting platform, the fixed column comprises two columns 1 and two columns 2 distributed in a rectangular shape, the sides of the columns 1 and 2 are provided with through holes 1, and the four corners of the lifting platform are provided with extension components, and one end of the extension component extending into the columns 1 and 2 through the through holes 1 is connected with a lifting rope; the tops of the columns 1 and 2 are provided with horizontally arranged fixed rods through mounting frames, a winding shaft is movably arranged inside the base, one end of the lifting rope away from the extension component is wound around the winding shaft, and the lifting rope is folded around the fixed rod and arranged in the columns 1 and 2; a driving motor and a controller are arranged on the base; through holes 2 are arranged on opposite sides of the two columns 1, and a plurality of protective baffles arranged at intervals are movably arranged inside the through holes 2, and a magnetic component is arranged at one end of the protective baffle, and an electromagnetic component is arranged at a position of the lifting rope close to the movable door, and the position of the electromagnetic component corresponds to the position of the magnetic component.

[0005] Preferably, a groove is provided on a side surface of the extension component.

[0006] Preferably, a clamping mechanism is provided inside the lifting platform for clamping and fixing the material in the lifting platform.

[0007] Preferably, the clamping mechanism comprises a telescopic component 1 installed on the inner wall of the lifting platform, and a clamping mesh plate is installed on one end of the piston rod of the telescopic component 1.

[0008] Preferably, a mounting cavity is provided at the bottom of the lifting platform, and three through holes are provided at intervals at the top of the mounting cavity. An auxiliary mechanism is provided in the mounting cavity to assist in loading or unloading materials into the lifting platform.

[0009] Preferably, the auxiliary mechanism includes a fixed seat installed at the bottom of the lifting platform, on which a telescopic component 2 is installed, and a mounting seat is installed at one end of the piston rod of the telescopic component 2 extending into the mounting cavity, and a plurality of movable rollers arranged at intervals are movably installed on the mounting seat, and the positions of the movable rollers correspond to the opening positions of the through hole 3.

[0010] Preferably, a limiting component is provided on the outer wall of the lifting platform.

[0011] Preferably, a positioning opening is provided on the top of the base, and the opening position of the positioning opening corresponds to the position of the fixing seat.

[0012] The beneficial effects of the present invention are: 1. Improve stability and safety: By setting a limit component on the outer wall of the lifting platform, a stable limit structure is formed with the first and second columns, which effectively prevents the horizontal deviation of the platform caused by lateral wind force or accidental impact during the lifting process, and improves the stability and safety of the equipment operation. At the same time, the limit component can adopt a roller guide structure or an elastic buffer mechanism to reduce friction resistance and enhance impact resistance, ensuring that the platform can still operate stably in harsh environments.

[0013] 2. Efficient material loading and unloading function: Auxiliary mechanisms are used to optimize the material loading and unloading process. The movable roller in the mounting cavity drives the mounting seat to rise and fall through the telescopic component 2, so that the movable roller extends to the inside of the lifting platform through the through hole 3. When pulling the material, the friction between the bottom of the material and the platform is effectively reduced, the material fluidity is improved, the difficulty of manual operation is reduced, and the operation efficiency is improved.

[0014] 3. Accurate positioning to ensure stable operation: Through the cooperation of the positioning port on the top of the base and the fixed seat, the lifting platform can be accurately positioned when it descends to the top of the base, ensuring that the platform will not shake or misalign when loading or unloading. At the same time, the fit 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 status of the platform can be monitored in real time, improving the intelligence of the equipment.

[0015] 4. The clamping mechanism improves the material fixing effect: A clamping mechanism is provided inside the lifting platform, which includes a clamping mesh plate that can be moved horizontally, and the clamping force is adjusted by a telescopic component, which can adapt to materials of different sizes and shapes, ensuring that the materials do not slip or tip over during the lifting process, thereby improving transportation safety. At the same time, the clamping mesh plate adopts a grid structure to reduce wind resistance and reduce the surface pressure of the material, thereby improving applicability.

[0016] 5. Structural optimization and smooth operation: By optimizing the layout of the lifting rope, it bypasses the fixed rod and passes through the groove on the side of the extension part, which enhances the guiding stability of the lifting rope, prevents the rope from deflecting or tangling, ensures a smooth lifting process, reduces vibration and impact during operation, and increases service life.

[0017] 6. Intelligent adaptation and strong adaptability: The lifting platform can realize the linkage of limit, clamping and auxiliary mechanisms through the automatic control system to ensure the accuracy and safety of material transportation. The movable roller of the auxiliary mechanism can be adaptively adjusted according to the size and shape of different materials, and the clamping mechanism can also adjust the clamping force according to the characteristics of the material, making it suitable for a variety of construction scenarios, improving construction efficiency and equipment adaptability.

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 the embodiments.

[0021] In one embodiment, referring to Figures 1 to 8 A material lifting platform for construction includes a base 1, a fixed column 25 and a lifting platform 4 are arranged on the top of the base 1, a movable door 3 is movably arranged on one side of the lifting platform 4, the fixed column 25 includes two columns 15 and two columns 24 distributed in a rectangular shape, and the sides of the columns 15 and the columns 24 are each provided with a through hole 17, and the four corners of the lifting platform 4 are each provided with an extension component 13, and one end of the extension component 13 extending into the columns 15 and the columns 24 through the through hole 17 is connected with a lifting rope 10; the tops of the columns 15 and the columns 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, and the end of the lifting rope 10 away from the extension part 13 is wound around the winding shaft 16. The lifting rope 10 is folded around the fixed rod 9 and arranged in the column 1 5 and the column 2 24; a driving motor 15 and a controller 23 are arranged on the base 1; a through hole 2 19 is opened on the opposite side of the two columns 5, and a plurality of protective baffles 6 arranged at intervals are movably installed inside the through hole 2 19, and a magnetic component 20 is arranged at one end of the protective baffle 6, and an electromagnetic component 12 is arranged near the movable door 3 of the lifting rope 10, and the position of the electromagnetic component 12 corresponds to the position of the magnetic component 20.

[0022] First, load the construction materials to be lifted onto the lifting platform 4, and close the movable door 3 set on one side of the lifting platform 4; then, the winding shaft 16 inside the base 1 is driven by the driving motor 15 to rotate, so that the lifting rope 10 at the end away from the extension component 13 is evenly wound, and the lifting rope 10 is guided by the fixed rod 9 and folded in half and arranged inside the column 1 5 and the column 2 24, and connected to the extension component 13, thereby driving the lifting platform 4 to rise synchronously to complete the lifting of the materials. At the same time, since the lifting rope 10 is hidden inside the column, entanglement and damage caused by exposure are avoided; when it is necessary to lower the lifting platform 4, the driving motor 15 runs in the reverse direction to unwind the winding shaft 16, and the lifting platform 4 descends steadily under the action of its own gravity, which is convenient for lowering the materials; during the lifting platform 4 lifting and lowering process, the controller 23 turns on the power of the electromagnetic component 12 through the switch. , so that the electromagnetic component 12 located near the movable door 3 and the magnetic component 20 at the corresponding position generate magnetic repulsion, thereby prompting the protective baffle 6 arranged on the column 1 5 through the through hole 2 19 to rotate to a horizontal state in a direction away from the electromagnetic component 12, and lock the movable door 3 to prevent the movable door 3 from opening by mistake and causing the material to fall off during the lifting process; when the lifting platform 4 and the electromagnetic component 12 continue to move so that the protective baffle 6 and the electromagnetic component 12 are misaligned, 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 time 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 a vertical state under the action of gravity, and releases the lock on the movable door 3, thereby facilitating the opening of the movable door 3.

[0023] As a preferred embodiment of the present invention, the movable door 3 is provided with a locking mechanism, which may adopt a mechanical lock or an electromagnetic lock structure to ensure that the movable door 3 remains in a closed state when it has not reached the specified position or the unlocking operation has not been performed, thereby preventing safety risks caused by accidental sliding of materials or misoperation by personnel.

[0024] As a preferred embodiment of the present invention, a groove 17 is provided on the side of the extension component 13, and the end of the lifting rope 10 away from the extension component 13 passes through the fixing rod 9 and is set in the groove 17. The groove 17 guides the lifting rope 10 stably to ensure the running stability and force balance of the lifting rope 10.

[0025] As a preferred embodiment of the present invention, a clamping mechanism 11 is provided inside the lifting platform 4 for clamping and fixing the material inside the lifting platform 4 .

[0026] As a preferred embodiment of the present invention, the clamping mechanism 11 includes a telescopic component 112 installed on the inner wall of the lifting platform 4. The telescopic component 112 is in the form of a hydraulic cylinder or an electric push rod to provide a stable and controllable driving force. One end of the piston rod of the telescopic component 112 is connected to the clamping mesh plate 111. The clamping mesh plate 111 is made of high-strength material and has a grid structure to reduce wind resistance and uneven force on the surface of the material. The telescopic component 112 can drive the clamping mesh plate 111 to move in the horizontal direction so that it clamps and fixes the material in the lifting platform 4.

[0027] 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, the clamping force of the telescopic component 112 is automatically adjusted to make the clamping mesh plate 111 close to the surface of the material, achieve stable clamping, and prevent 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 ensure stability while avoiding excessive pressure on the material, thereby improving the stability and applicability of the equipment.

[0028] As a preferred embodiment of the present invention, an installation cavity 22 is provided at the bottom of the lifting platform 4, and a through hole 3 21 is provided at the top of the installation cavity 22 at intervals. An auxiliary mechanism 18 is provided in the installation cavity 22 for assisting in loading or unloading materials into the lifting platform 4.

[0029] 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, and a telescopic component 184 is installed on the fixed seat 183. The telescopic component 184 adopts an electric push rod, a cylinder or a hydraulic cylinder structure to provide stable lifting power. One end of the piston rod of the telescopic component 184 extends into the installation cavity 22 and is connected to the installation seat 182. The installation seat 182 is made of high-strength material to ensure bearing capacity and stability.

[0030] A plurality of movable rollers 181 arranged at intervals are movably mounted on the mounting seat 182. The movable rollers 181 are made of low-friction material and supported by bearings to reduce rotational resistance. The arrangement position of the movable rollers 181 corresponds to the through hole 3 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 started.

[0031] When performing the loading or unloading operation, the telescopic component 2 184 drives the mounting seat 182 to move upward, so that the movable roller 181 extends to the inside of the lifting platform 4 through the through hole 3 21 and contacts the bottom of the material. When the material needs to be moved, the movable roller 181 can effectively reduce the friction between the material and the lifting platform 4, so that the material slides smoothly under a small driving force, thereby improving the efficiency of loading or unloading.

[0032] 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 that it can maintain a stable auxiliary effect under various working conditions. At the same time, the structure of the mounting seat 182 can be optimized according to the load requirements, so that it can provide reliable support under different material weight conditions, further improving the adaptability and operating stability of the equipment.

[0033] As a preferred embodiment of the present invention, the outer wall of the lifting platform 4 is provided with a limiting component 14, and the limiting components 14 are arranged at intervals along the circumference of the lifting platform 4. Two adjacent limiting components 14 are respectively located on the sides of the column 1 5 and the column 2 24, and form a stable limiting matching structure with the column 1 5 and the column 2 24. The limiting component 14 is made of wear-resistant and impact-resistant material, 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 durability.

[0034] During the lifting and lowering process of the lifting platform 4, the limiting component 14 limits its horizontal displacement by fitting with the column 1 5 and the column 2 24, preventing horizontal deviation caused by factors such as lateral wind force, accidental impact or eccentric load, and ensuring that the lifting platform 4 runs stably along the predetermined track. The structure of the limiting component 14 may include a roller guide mechanism, so that when it contacts the column 1 5 and the column 2 24, the friction resistance can be reduced by the rotation of the roller, thereby improving the stability of the overall operation.

[0035] In addition, the limiting component 14 can be equipped with a dynamic adjustment mechanism, so that it can automatically adjust the gap between the column 1 5 and the column 2 24 according to different working conditions to adapt to the limiting requirements under different load conditions, thereby further improving the safety and reliability of the equipment.

[0036] As a preferred embodiment of the present invention, a positioning opening 2 is provided at the top of the base 1, and the opening position of the positioning opening 2 corresponds to the position of the fixing seat 183, and is precisely matched according to the size and shape of the fixing seat 183, so as to ensure that when the lifting platform 4 is lowered to the top of the base 1, the fixing seat 183 can be smoothly embedded in the positioning opening 2 to achieve precise positioning. A buffer pad is provided on the inner wall of the positioning opening 2 to reduce the impact when the fixing seat 183 is inserted and to improve the durability of the positioning structure.

[0037] When the lifting platform 4 is lowered onto the base 1 and docking is completed, the fixing seat 183 is inserted into the positioning opening 2. By stabilizing the fixing seat 183, the lifting platform 4 is ensured to remain horizontal and stable during the loading and unloading process, and the material is prevented from being unevenly piled or slipping due to the shaking or deviation of the platform. The positioning opening 2 can adopt a conical guide structure so that the fixing seat 183 can be gradually guided to enter even when the platform is slightly offset, thereby improving the docking accuracy.

[0038] In addition, the limit structure can also be used as a part of the position monitoring of the lifting platform 4, and whether the fixing seat 183 is accurately embedded in the positioning port 2 is detected by a sensor or a mechanical limit, so as to determine whether the lifting platform 4 is offset. If the fixing seat 183 fails to be correctly inserted 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, thereby improving the safety and reliability of the overall operation.

[0039] 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 according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
