Description

Technical Field

[0001] This utility model belongs to the field of unloading platform technology, and in particular relates to an intelligent unloading platform with horizontal material delivery function. Background Technology

[0002] A material unloading platform is a type of mechanical equipment primarily used to unload materials or goods from a height. It is commonly used in construction sites, ship docks, warehouses, and logistics centers. It allows for the rapid and safe transfer of unloaded materials to the required location, ensuring the materials remain undamaged and free from cracks, thus guaranteeing unloading efficiency and quality. Existing material unloading platforms can be categorized into four types: mobile, ground-mounted, cantilevered, and telescopic. Based on the main materials used, they are classified into steel pipe unloading platforms and steel section cantilevered unloading platforms. The appropriate method can be selected based on the construction requirements. Currently, the most common type is the steel section cantilevered unloading platform, which offers high safety and a wide range of applications. The steel section cantilevered unloading platform uses channel steel, I-beams, and other structural steel sections as main and secondary beams, welded into a planar load-bearing frame. One end rests on the floor slab or is anchored to the exterior wall structure of the building, while the other end is suspended by steel wire ropes.

[0003] To further enhance the safety of unloading platforms, in the field of smart construction sites, overload alarm unloading platforms for cantilevered steel sections have been developed. However, these platforms simply add sensors to collect data on the actual load or stress borne by the platform, without significant structural or construction improvements. While they provide some degree of safety management, the common method of transportation is manual handling, which means workers have excessive contact with materials, posing a safety hazard. Moreover, compared to other common unloading platforms, the workers' working hours are the same, so they do not truly achieve the goal of ensuring safety while simultaneously improving efficiency and reducing costs.

[0004] Therefore, this application designs an intelligent unloading platform with horizontal material delivery function to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Reference Figures 1-9 As shown, this embodiment provides an intelligent unloading platform with horizontal material delivery function, including:

[0036] The carrying mechanism includes a carrying platform 1 and a carrying track 2 set on the carrying platform 1, which is used to limit the material transport trajectory;

[0037] The material conveying mechanism includes a material conveying trolley 3 mounted on the bearing rail 2, a braking assembly mounted on the material conveying trolley 3, and the braking assembly being positioned between the material conveying trolley 3 and the bearing rail 2.

[0038] A locking mechanism is installed between the material conveying trolley 3 and the carrying rail 2. The locking mechanism includes a material unloading locking assembly and a transfer locking assembly.

[0039] The control mechanism includes a traction component and a self-driving component that drive the material handling trolley 3 to move;

[0040] The obstacle avoidance mechanism is installed on the guard wall in the direction of movement of the material transport trolley 3.

[0041] This utility model discloses an intelligent unloading platform with horizontal material delivery function. The material transport trolley 3 of the transport mechanism moves on the support rail 2 on the support platform 1 to realize the transportation of materials. The braking component is used to brake the material transport trolley 3 on the support rail 2, which facilitates the control of the transport trolley. The locking mechanism is used to control the positional relationship between the material transport trolley 3 and the support rail 2. The unloading locking component is used to ensure the stability of the material transport trolley 3 when loading and unloading materials at both ends of the support rail 2, preventing the material transport trolley 3 from shaking during loading and unloading, and improving safety. The transfer locking component of the locking mechanism is used to lock the material transport trolley 3 when changing layers. The system is tightly fixed to prevent the material transport trolley 3 from tipping over or moving and causing major safety accidents. The traction component of the control mechanism is used to move the material transport trolley 3, which is fully loaded with materials and has good stability. The self-driving component can be used alone or in combination with the traction component to drive the material transport trolley 3. It has low power requirements, small space requirements, and does not require manual resetting of the material transport trolley 3, thus reducing labor costs. The obstacle avoidance mechanism is set on the guardrail in the direction of movement of the material transport trolley 3. It is used to measure and control the position of the material transport trolley 3 relative to the guardrail, thereby controlling the movement of the material transport trolley 3 and preventing the material transport trolley 3 from directly colliding with the guardrail, thus improving the safety of the transportation process.

[0042] Furthermore, the carrying track 2 includes a set of parallel guide rails 19 arranged on the carrying platform 1, and the material transport trolley 3 moves on the guide rails 19.

[0043] Furthermore, in this embodiment, the guide rail 19 adopts a circular or square shape according to national standards and is pre-welded to the bearing platform 1; to prevent the bottom of the material transport trolley 3 from scraping the ground during operation, steel such as I-beams can be welded between the guide rail 19 and the bearing platform 1 to raise the height of the guide rail 19.

[0044] Furthermore, in order to stop the material transport trolley 3 after reaching the designated position, a limit switch is installed on the side of the guide rail 19. When the material transport trolley 3 triggers the limit switch, the control part is powered off. After losing power, the material transport trolley 3 continues to move a certain distance by inertia and then stops at the designated position.

[0045] Furthermore, to avoid safety hazards caused by personnel during construction, an intelligent detection system can be installed. This system can utilize cameras combined with computer vision technology, such as target detection and tracking algorithms, to identify and count operators on the carrying platform 1. The specific installation location should fully cover the area on the carrying platform 1; it can be installed above, to the side, or in other suitable locations, depending on the platform's structure and layout. When materials are unloaded from one floor and need to be moved to another, the intelligent detection system monitors whether there are still workers unloading or performing other operations on the carrying platform 1. If workers are present, the floor is moved after completion; otherwise, the floor is moved immediately. Installing an intelligent detection system ensures worker safety during operations. Monitoring the number of operators helps ensure that the number of people on the carrying platform 1 does not exceed the safe capacity, which helps prevent overcrowding and reduce the risk of accidents. Secondly, it improves efficiency and resource allocation. Knowing the actual number of personnel on the carrying platform 1 helps to allocate resources more effectively, including human resources and equipment, which can improve workflow efficiency and reduce potential waste.

[0046] Further optimizing the design, the material transport trolley 3 includes a body 4, with several wheels 5 mounted on the bottom of the body 4. These wheels 5 roll and contact the load-bearing rail 2. A braking assembly is located at the bottom of the body 4 and detachably connected to the load-bearing rail 2. A traction assembly and a self-driving assembly are respectively connected to the body 4 via transmission. The bottom of the body 4 of the material transport trolley 3 moves on the guide rail 19 via the wheels 5. The braking assembly on the body 4 controls the stability of the body 4 against the load-bearing rail 2, while the traction assembly is located on the body 4 to pull the fully loaded material transport trolley 3. The self-driving assembly is used to reset the empty body 4, enabling reloading of materials.

[0047] Furthermore, the body 4 of the material transport trolley 3 is the main body for loading and unloading materials, and it is also the most important structure in the device for completing the material loading and unloading process. The body 4 has multiple railings 18 at different heights. Small materials are placed on the steel plate platform of the body 4. Longer materials such as steel pipes and steel plates are placed on the railings 18. This design can make reasonable use of limited space and transport more materials.

[0048] Furthermore, in order to reduce construction accidents caused by overloading, a sensor 20 is installed on the vehicle body 4. The sensor 20 continuously monitors whether the material transport trolley 3 exceeds the prescribed weight after loading materials, so as to avoid construction accidents.

[0049] Furthermore, in this embodiment, the wheel 5 uses a U-shaped wheel, which automatically centers on the guide rail 19, reducing the friction between the side of the wheel 5 and the guide rail 19 during operation, thus reducing the service life of the wheel 5 and the guide rail 19; at the same time, various forms such as V-shaped wheels, H-shaped wheels, and L-shaped wheels can also be used, which will not be described in detail here.

[0050] The design is further optimized so that the braking assembly includes a brake block 6 mounted on the vehicle body 4, a brake plate 7 mounted on the support rail 2, and the brake block 6 is slidably connected to the brake plate 7 and in limiting contact with the brake plate 7. (See attached diagram.) Figure 2 Brake block 6 is installed on the vehicle body 4, and brake plate 7 is installed on guide rail 19. When braking is required, brake block 6 rubs against brake plate 7 to achieve braking of vehicle body 4 through friction.

[0051] Further, refer to the appendix. Figure 3 Brake plate 7 is installed on the support platform 1 and is suitable for different usage scenarios.

[0052] Furthermore, the brake block 6 in this embodiment is a pneumatic disc brake, which has the advantages of being environmentally friendly, durable, and low-cost. It generates axial thrust from the piston on the cylinder, thereby forming torque transmission. Once the cylinder is depressurized, the spring will push the piston back to its initial position, and the torque will disappear. When using a spring brake, the axial thrust required to generate torque is generated by the spring. Applying appropriate air pressure to the piston will release the brake. The pneumatic disc brake mainly consists of an electrically controlled brake pedal, an air compressor, a cylinder, and a brake drum. When the operator presses the brake pedal, the brake valve on the air compressor will open, allowing air pressure to enter the cylinder. The piston in the cylinder will move outward, causing the brake pads on the brake drum to rub against the brake track, thereby generating braking force. The working principle of the air brake can be summarized as using air pressure to drive the piston, and achieving the braking effect through the contact between the friction brake pads and the brake drum. Its advantages are stable and reliable braking force, and it is not prone to overheating during braking, making it suitable for heavy-duty vehicles.

[0053] The solution is further optimized. The unloading locking assembly includes a locking block 8 that is movably connected to the bottom of the vehicle body 4. A stop block 9 that is adapted to the locking block 8 is set on the bearing rail 2. The locking block 8 and the stop block 9 are connected in a limiting manner. The locking block 8 is controlled by the worker through a control rod. When the material transport trolley 3 is loaded with materials and moving to one side, the control lever on the material transport trolley 3 is placed horizontally. At this time, the locking block 8 at the bottom of the material transport trolley 3 is in a relaxed and falling state. When the trolley moves to the stop 9 in front of the designated unloading position, the locking block 8 is pushed up by the inclined surface of the stop 9. When passing the stop 9, the locking block 8 automatically falls down due to gravity. After the material transport trolley 3 stops, the interaction between the locking block 8 and the stop 9 prevents the trolley from moving to the other side. After the material is unloaded from the material transport trolley 3, the worker pulls the control lever and tightens the locking block 8 to move upward past the stop 9, allowing the material transport trolley 3 to move past the stop 9. After reaching the designated loading position, the control lever is lowered, and the locking block 8 relaxes and falls down. This process is repeated. The locking method of the locking block 8 is simple, but it can ensure long-term stable operation in harsh environments such as construction sites.

[0054] Furthermore, the up-and-down movement of the locking block 8 can be achieved using a pulley system, with ropes connecting the locking block 8 and the control lever respectively.

[0055] Furthermore, the locking block 8 can also be designed to be electrically controlled.

[0056] The scheme is further optimized. The transfer locking assembly includes a locking rod 10 movably connected to the vehicle body 4. The support platform 1 is provided with a locking hole 11 that is adapted to the locking rod 10. The locking rod 10 is limited and connected in the locking hole 11. The side wall of the locking rod 10 is provided with a limiting piece 12. The side wall of the locking hole 11 is provided with a limiting hole 13 that is adapted to the limiting piece 12. The limiting piece 12 is limited and connected in the limiting hole 13. When the materials in one floor have been loaded and unloaded and need to be moved to another floor for further loading and unloading, the worker presses the locking control button on the material trolley, and the lower end of the locking rod 10 enters the locking hole 11 on the main body of the bearing platform 1. The locking hole 11 is slightly larger than the diameter of the locking rod 10, and only a limiting groove is opened at a suitable position for the limiting piece 12 to pop out. Since the gap between the locking rod 10 and the locking hole 11 is not large, the limiting piece 12 at the lower end of the locking rod 10 is not enough to pop out. When the locking rod 10 is pressed down to the position of the limiting groove, under the action of the elastic potential energy stored in the compressed spring, the limiting piece 12 pops out from inside the locking rod 10 and is stuck in the limiting groove to fix the material transport trolley 3. After the floor change is completed, the button on the locking rod 10 is pressed to compress the spring, and the limiting piece 12 connected to the spring retracts together. The locking rod 10 can be pulled out smoothly, and the material transport trolley 3 can move freely on the guide rail 19.

[0057] Further optimizing the design, the traction assembly includes a traction motor 14 mounted on the support platform 1, which is connected to a traction ring 15 mounted on the vehicle body 4. A flexible traction cable 16 is provided between the traction motor 14 and the traction ring 15. The traction motor 14 is fixed to the left side of the support platform 1 by bolts. The traction cable 16 is wound on a drum connected to the output shaft of the traction motor 14. The hook at the other end of the traction cable 16 is connected to the traction ring 15 of the material transport trolley 3, providing horizontal traction force to the material transport trolley 3 so that the material transport trolley 3 can run on the guide rail 19.

[0058] Furthermore, for economic reasons, this embodiment only installs a traction motor 14 on one side of the carrying platform 1. Therefore, after unloading the materials, the material transport trolley 3 needs to be manually pulled by workers to the designated loading position. To reduce the labor of workers, traction motors 14 can be installed on both sides of the guide rail 19, so that the material transport trolley 3 can run without manual intervention.

[0059] Furthermore, it should be noted that when the traction motor 14 is working, the traction cable 16 is connected to the material transport trolley 3 and provides horizontal traction force to the material transport trolley 3. At this time, the traction cable 16 is in a taut state. However, when the material transport trolley 3 triggers the limit switch, the traction motor 14 is de-energized and stops working. But the material transport trolley 3 will continue to run a certain distance under the action of inertia. At this time, the traction cable 16 is in a slack state. The bottom of the material transport trolley 3 is low to the device bearing platform 1. When the traction cable 16 is in a slack state, it is very likely to come into contact with the ground and cause unnecessary wear. Therefore, the service life of the traction cable 16 can be ensured by raising the height of the guide rail 19 or adding a tensioning device to the traction cable 16.

[0060] Furthermore, since the traction motor 14 is directly fixed on the bearing platform 1, the traction motor 14 can be controlled by a wired operating handle or further upgraded to a wireless operating handle. The operating handle can be suspended near the power supply box. If more convenient control of the traction motor 14 is required, a wireless remote control operating handle can be used.

[0061] Furthermore, the traction motor 14 in this embodiment is an AC motor, which has the advantages of wide application, low cost and simple operation. The external traction scheme of the traction motor 14 can reduce the cost of the guide rail 19 pulley-assisted cantilever unloading bearing platform 1 device.

[0062] In a further optimized design, the self-driving component includes a self-driving motor 17, which is connected to several wheels 5 located at the same end of the vehicle body 4. The self-driving motor 17 is connected to a driver and a controller. The driver is connected to the wheels 5, and the controller is connected to the driver. The driver and controller are connected to the self-driving motor 17 via wires, and the driver is connected to the wheels 5 via a chain or gears. A battery can be installed on the side or bottom of the vehicle body 4 to provide DC power to the self-driving motor 17.

[0063] Furthermore, the material transport trolley 3 loads materials on the right side of the carrying platform 1. Powered by the battery, the self-drive motor 17 is started. The driver and controller control the material transport trolley 3 to move from the right side of the guide rail 19 to the left side. When the material transport trolley 3 reaches the designated unloading position, the limit switch is triggered to cut off the power to the self-drive motor 17, the material transport trolley 3 stops running, stops and locks, and begins unloading. After unloading is completed, the reverse rotation is started, the self-drive motor 17 drives the trolley back to the loading position, and the limit switch is triggered to stop.

[0064] Furthermore, if an accident occurs while the vehicle is moving, it can be brought to an emergency stop by operating the handle and the aforementioned braking device together.

[0065] Furthermore, to facilitate safe operation and management by on-site workers and avoid safety hazards caused by external wiring of the motor at the bottom of the trolley, the self-drive mode prioritizes the use of a wireless remote control. A wireless operating handle was designed and developed to realize single-stage inching, two-stage inching, automatic forward, automatic backward and stop functions.

[0066] Furthermore, the self-driven motor 17 in this embodiment is a DC motor, which is a motor that realizes the mutual conversion of DC electrical energy and mechanical energy. Compared with AC motors, the self-driven motor 17 can achieve stepless speed regulation and does not require the cooperation of other equipment; it only needs to change the input or magnetic excitation voltage and current. It can also achieve forward and reverse rotation, controlling the forward and backward movement of the trolley. In addition, DC motors have high starting torque, good starting characteristics, and high operating efficiency. The brushless DC motor mainly relies on the Hall sensor 20 or back electromotive force to obtain the current rotor position, and then determines which two phase windings should be energized at the current time according to the set commutation table, thereby obtaining a certain angle between the stator magnetic flux and the reverse rotor magnetic flux, enabling the motor to run.

[0067] Further optimization of the solution includes obstacle avoidance mechanisms such as infrared obstacle avoidance systems, ultrasonic obstacle avoidance systems, or laser obstacle avoidance systems. Considering that the length and stacking height of the materials transported by the material handling trolley 3 may vary, and collisions with the protective wall may occur during transport, an obstacle avoidance mechanism is installed on the protective wall in front of the material handling trolley 3 to prevent collisions. This application proposes several different obstacle avoidance measures:

[0068] Infrared obstacle avoidance system

[0069] The infrared obstacle avoidance system determines the position and distance of the material transport trolley 3 and the materials by detecting reflected infrared light. When the distance between the material transport trolley 3 and the materials and the protective wall is outside the set obstacle avoidance range, the material transport trolley 3 can continue to operate; conversely, the motor will stop working, causing the material transport trolley 3 to decelerate and stop, thus achieving the purpose of obstacle avoidance. To monitor the material transport trolley 3 and the materials as a whole, multiple infrared modules can be installed on the front protective wall to form an infrared matrix, eliminating monitoring instability caused by installation position.

[0070] Ultrasonic obstacle avoidance system

[0071] The ultrasonic obstacle avoidance system determines the position and distance of the material transport trolley 3 and the material by measuring the round-trip time of the sound waves. When the round-trip time measured by the ultrasonic obstacle avoidance system is outside the set obstacle avoidance range, the material transport trolley 3 can continue to run; otherwise, the motor will stop working, thereby causing the material transport trolley 3 to decelerate and stop.

[0072] Laser obstacle avoidance system

[0073] The laser obstacle avoidance system is installed on the protective walls on both sides of the material transport trolley 3, with one side being the transmitter and the other the receiver. When there is no material transport trolley 3 or material obstructing the path, the receiver can receive the laser emitted by the transmitter. However, when the emitted laser is blocked, the receiver does not receive the laser, the motor stops working, and the material transport trolley 3 slows down and comes to a stop.

[0074] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.
