Description

Technical Field

[0001] This application relates to the technical field of building construction, and in particular to a cantilevered track-type unloading platform. Background Technology

[0002] In the construction industry, unloading platforms are crucial equipment for material transfer and unloading, and their performance directly impacts construction efficiency, cost, and safety. Efficient, safe, and flexible unloading platforms can significantly improve construction efficiency, reduce manual handling workload, and lower construction costs. They enable the rapid and orderly transfer of building materials from transport equipment to the construction area.

[0003] To facilitate material unloading and transfer, conventional ground-mounted unloading platforms are used. These platforms are directly built on the ground, relying on a solid foundation to support the weight of materials and equipment. However, existing unloading platforms lack flexibility and reliability in adjusting and securing the support rails. They struggle to precisely adjust and securely lock the rails to meet varying unloading requirements, limiting their flexibility and applicability. When dealing with excessively long or heavy materials, existing unloading platforms, lacking effective support and support, cannot adequately hold the materials when they are suspended for a significant distance. This can lead to tilting and falling materials, impacting construction efficiency and posing significant safety hazards, seriously endangering the lives of construction workers.

[0004] In view of the aforementioned technologies, it is necessary to propose a cantilevered track-type unloading platform to solve the above problems. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a cantilevered track-type unloading platform.

[0006] This application provides a cantilevered track-type unloading platform, which adopts the following technical solution: A cantilevered track-type unloading platform includes: A cantilevered platform is cantilevered at the floor slab. The cantilevered platform has a concave surface, and a limit slider is provided in the concave surface. A load-bearing rail is slidably provided on the limit slider, and the load-bearing rail carries the unloading vehicle. A combination frame is symmetrically arranged on both inner sides of the concave surface of the cantilever platform. A limiting groove is formed on one side of the combination frame, and a limiting block is provided on the side of the load-bearing rail. The limiting block is disposed within the limiting groove and serves to limit the load-bearing rail within the concave surface. A locking mechanism is used to lock the bearing rail after it slides within the concave surface. The locking mechanism includes several support plates disposed on the side of the bearing rail, several locking cylinders penetrating the support plates, and several locking blocks disposed above the combined frame. Several locking grooves are penetrating the top of the combined frame. The output end of the locking cylinder is connected to the locking block and inserts the locking block into the locking groove.

[0007] By adopting the above technical solution, the cantilever platform is cantilevered on the floor slab, with a concave surface and a limiting slider inside. The load-bearing rail slides on the limiting slider, allowing for flexible adjustment of the load-bearing rail position to adapt to different unloading needs, enabling the unloading vehicle to unload at the appropriate position. The combined frame is symmetrically arranged on both inner sides of the concave surface, with a limiting groove on one side. The limiting block on the side of the load-bearing rail is placed in the limiting groove, preventing the load-bearing rail from shaking or shifting within the concave surface and ensuring the stability of the load-bearing rail operation. The locking mechanism functions after the load-bearing rail slides to the correct position. A locking cylinder is installed through the support plate on the side of the load-bearing rail, and a corresponding locking block is installed above the combined frame. A locking groove is installed through the top of the combined frame, and the output end of the locking cylinder is connected to the locking block. Inserting the locking block into the locking groove can firmly lock the position of the load-bearing rail, preventing displacement of the load-bearing rail during unloading and ensuring the safe and stable operation of the unloading work.

[0008] Optionally, a plurality of rebound blocks are rotatably provided on the top of the bearing track. The rebound blocks are inclinedly disposed on the top of the bearing track. Springs are provided on the inner side of the rebound blocks and the top of the bearing track, and the springs support the inclined rebound blocks.

[0009] By adopting the above technical solution, several inclined rebound blocks are rotatably installed on the top of the bearing rail, and springs are installed on the inner side of the rebound blocks and the top of the bearing rail to support the rebound blocks. When the unloading vehicle moves forward on the bearing rail, the wheels of the unloading vehicle will squeeze the rebound blocks to make them rotate, and the springs will be compressed. When the unloading vehicle attempts to reverse, the inclined rebound blocks will abut against the wheels of the unloading vehicle under the support of the springs, forming a reverse blocking force on the wheels, thereby effectively preventing the unloading vehicle from reversing and ensuring the stability and safety of the unloading process.

[0010] Optionally, it also includes a top support mechanism, which includes a connecting frame disposed at the end of the bearing track, a plurality of adjusting cylinders disposed on the connecting frame, a rotating frame disposed at the output end of the adjusting cylinders, and a top support plate rotatably disposed at the rotating frame. The top support plate is used to support the material extending on the unloading vehicle.

[0011] By adopting the above technical solution, when the unloading vehicle transports the material to the carrying track, if the material has an extended part, the output end of the adjusting cylinder can push the rotating frame, thereby driving the top support plate to move to a suitable position. The rotating top support plate set at the rotating frame can flexibly adjust the angle to better fit the material, effectively supporting the extended material on the unloading vehicle, preventing the material from falling or tilting due to an unstable center of gravity, and ensuring the stability and safety of the unloading process.

[0012] Optionally, a positioning block is provided at the end of the bearing track, the connecting frame is sleeved on the positioning block, and a plug-in plate is provided through the connecting frame and plugged into the positioning block.

[0013] By adopting the above technical solution, accurate installation and positioning of the connecting frame and the end of the bearing rail can be achieved, improving installation efficiency and accuracy; and through the plug-in cooperation of the plug plate and the positioning block, the connection stability between the connecting frame and the bearing rail is enhanced, ensuring that the top support mechanism can be firmly connected to the bearing rail during operation, and reliably support the material extending on the unloading vehicle.

[0014] Optionally, it also includes a splicing plate, wherein the top support plate is provided with a splicing groove, and both ends of the splicing plate are respectively disposed in the splicing groove. The end face of the splicing plate and the end face of the top support plate are on the same horizontal plane, and the splicing plate supports the material.

[0015] By adopting the above technical solution, splicing grooves are set on the top support plate, and both ends of the splicing plate are placed in the splicing grooves with their end faces on the same horizontal plane as the end faces of the top support plate. This increases the contact area of ​​the top support material, making the material support more stable and preventing the material from tilting or slipping due to insufficient support area. This improves the stability and safety of the material during the unloading process and ensures that the unloading work can proceed smoothly.

[0016] Optionally, a self-locking motor is provided through the rotating frame, and the output end of the self-locking motor is connected to the tail end of the top support plate. Arc-shaped plates are provided on both sides of the end of the connecting frame, and an electromagnet is provided on the inner side of the arc-shaped plates. A magnetic plate is provided on the side of the top support plate. After the angle of the top support plate is adjusted, the electromagnet is energized and magnetically attracts the magnetic plate.

[0017] By adopting the above technical solution, the angle of the top support plate can be adjusted to meet the supporting needs of extended materials on different unloading vehicles. Electromagnets are installed on the inner side of the arc-shaped plates on both sides of the connecting frame end, and magnetic plates are installed on the side of the top support plate. After the angle of the top support plate is adjusted to the correct position, the electromagnet is energized, and the electromagnet generates magnetic force to attract the magnetic plates. The magnetic attraction between the electromagnet and the magnetic plates is used to stably fix the top support plate in the adjusted angle position, so as to prevent the top support plate from shifting its angle due to external force during the supporting of materials, thereby ensuring the stable supporting of materials by the top support plate and improving the safety and stability of the unloading process.

[0018] Optionally, it also includes a plurality of reinforcing plates, which are arranged at equal intervals between the symmetrical bearing rails, and the two sides of the plurality of reinforcing plates are respectively fixedly connected to the inner side of the bearing rails.

[0019] By adopting the above technical solutions, the connection strength and stability between the load-bearing rails can be effectively enhanced. The evenly spaced arrangement makes the stress on each part of the load-bearing rails more uniform, avoiding excessive local stress that could lead to deformation or damage, thereby improving the structural reliability and safety of the entire cantilevered track unloading platform when carrying unloading vehicles and materials.

[0020] Optionally, stabilizing seats are provided on both sides of the cantilever platform. The stabilizing seats are fixedly connected to the floor slab. Anti-slip pads are provided on both the stabilizing seats and the bottom of the cantilever platform, and the anti-slip pads are in contact with the surface of the floor slab.

[0021] By adopting the above technical solution, the cantilever platform can be supported and fixed, enhancing its stability. At the same time, anti-slip pads are set at the bottom of the stabilizing seat and the cantilever platform. The anti-slip pads are in contact with the floor surface. By utilizing the principle of increasing friction, the cantilever platform can be effectively prevented from sliding or shifting on the floor, further improving the safety and stability of the entire cantilever track unloading platform during use.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The concave surface of the cantilever platform works in conjunction with the limiting slider and the bearing rail, and the combination frame and the limiting block work together to flexibly adjust the position of the bearing rail. Then, the locking mechanism securely locks it, effectively solving the problem that the existing unloading platform is inflexible and unreliable in adjusting and fixing the position of the bearing rail. 2. The top support mechanism can provide support for the materials extending on the unloading vehicle, making up for the lack of an effective support structure in the existing unloading platform when facing materials that are too long or too heavy, and preventing the materials from tilting or falling.
