Description

Technical Field

[0001] The present application relates to the field of mining machinery and equipment, and in particular to a mobile unloading platform for an excavation working face. Background Art

[0002] In modern mining operations, material transportation is crucial for ensuring efficient and safe mine operations. Efficient material transportation not only ensures smooth production processes but also effectively reduces production costs. However, due to the complexity of mine geology and the unique layout of tunnels, material transportation presents numerous challenges.

[0003] Currently, rubber-tyred trucks remain the most commonly used material transport tool in many mines. Their adaptability and flexibility allow them to operate in harsh environments, improving transport efficiency and reducing the physical burden on workers. Furthermore, their relative simplicity and ease of training make them a preferred material transport solution in mines.

[0004] While rubber-tyred trucks play a vital role in transporting materials in mines, their inherent limitations cannot be ignored. They still require a high level of manual loading and unloading, which not only increases workers' workload but also exposes them to a higher risk of injury during frequent loading and unloading. Their limited transport capacity makes it difficult to meet the demands of large-scale, high-density material transport. This is especially true when responding to emergencies, as the system's response speed and flexibility are insufficient, making it difficult to quickly adjust transport plans. Utility Model Content

[0029] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0030] Although rubber-wheeled trucks play an important role in the transportation of materials in mines, their inherent limitations cannot be ignored. The rubber-wheeled truck transportation method still requires a high level of manual loading and unloading of materials, which not only increases the labor intensity of workers, but also exposes them to a higher risk of work-related injuries during frequent loading and unloading. The transportation capacity of rubber-wheeled trucks is limited, and it is difficult to meet the needs of large-scale, high-density material transportation. Especially when responding to emergencies, the system's response speed and flexibility are insufficient, making it difficult to quickly adjust the transportation plan. The specific structure of the mobile unloading platform for the excavation working face provided in this application is described in detail below in conjunction with the accompanying drawings.

[0031] Reference Figure 1 As shown, an embodiment of the present application provides a mobile unloading platform for an excavation working face, comprising: a base 1, an unloading platform 2, a gantry 3 and an I-frame 4.

[0032] The unloading platform 2 is arranged on the top of the base 1 and is used for placing and unloading materials, providing a flat and spacious working area, which is convenient for workers to load, unload and stack materials and improve work efficiency.

[0033] The gantry 3 is erected on both sides of the unloading platform 2 to increase the overall rigidity and stability of the unloading platform 2, ensure the structural safety under heavy load, and reduce the risk of deformation and damage.

[0034] The I-frame 4 is erected on the top of the unloading platform 2 and is connected to the crossbeam of the gantry 3 to provide a solid supporting structure.

[0035] Pneumatic hoisting devices 5 are provided on both sides of the top beam of the I-frame 4, which are driven by compressed air and are suitable for situations where there is no power supply or the power supply is unstable in the mine, thereby improving hoisting efficiency and safety and reducing the physical labor of workers.

[0036] The embodiment of the present application provides a mobile unloading platform for the excavation working face. By setting the unloading platform 2 on the top of the base 1, it not only provides sufficient space for the loading and unloading of materials, but also facilitates workers to quickly and accurately complete the stacking of materials, reduces unnecessary physical exertion during the handling process, and thus significantly improves the working efficiency. The design of the gantry 3 enhances the rigidity and stability of the entire unloading platform, especially when carrying heavy objects, it can effectively reduce structural deformation and potential damage risks. The connection between the I-frame 4 and the crossbeam of the gantry 3 constructs a more stable support system. Pneumatic lifting devices 5 are provided on the two side beams on the top of the I-frame 4, which not only ensures the safety of the lifting operation, but also uses compressed air as the power source, making the device particularly suitable for occasions where the power supply inside the mine is unstable or lacks power supply. The application of the pneumatic lifting device 5 greatly reduces the labor intensity of the workers, while improving the lifting speed and accuracy.

[0037] Reference Figure 2As shown, in some embodiments, the pneumatic lifting device 5 includes a pulley 51, a pneumatic lifting chain 52, a pneumatic hoist 53 and a hook 54 connected in sequence; the pneumatic lifting chain 52 is used to connect the pulley 51 and the pneumatic hoist 53 to provide stable lifting support and ensure stability and safety during the lifting process. The pneumatic hoist 53 is used to lift and lower materials and is driven by compressed air. It is suitable for situations where there is no power supply or unstable power supply in the mine, improves lifting efficiency and safety, and reduces the physical labor of workers. The hook 54 is used to fix and lift materials, provides a reliable connection point, and ensures the safety and stability of materials during the lifting process. The pulley 51 is slidably connected to the side beam of the I-frame 4, which increases the moving range and flexibility of the lifting device, facilitates lifting operations in different positions, and improves work efficiency.

[0038] The pulley 51 is slidably connected to the side beams of the I-frame 4, allowing the pneumatic lifting device 5 to move freely within a certain range, increasing the flexibility of the lifting operation and allowing workers to easily lift at different locations without having to frequently move the entire unloading platform, thereby improving work efficiency. The pneumatic lifting chain 52 not only connects the pulley 51 and the pneumatic hoist 53, but also provides stable lifting support, ensuring stability and safety during the lifting process. The pneumatic hoist 53 is driven by compressed air, avoiding the power supply issues that may be encountered by traditional electric hoists. Especially in environments such as mines where explosive gases may be present, the use of the pneumatic hoist 53 greatly reduces safety hazards. The pneumatic hoist 53 can efficiently lift and lower materials. It uses compressed air as a power source and is not restricted by power supply, making it very suitable for the working environment within the mine. In addition, the hook 54 provides a reliable connection point for the material, ensuring the safety and stability of the material during the lifting process, reducing work interruptions caused by accidents such as falling materials, and thus improving overall work efficiency.

[0039] Reference Figure 1 and Figure 2 As shown, in some embodiments, the pneumatic lifting device 5 is arranged in the guide rails of the two side beams on the top of the I-frame 4 and can slide freely along the guide rails.

[0040] By placing the pneumatic lifting device 5 within the guide rails on either side of the top beam of the I-frame 4, not only does the flexibility and efficiency of the lifting operation increase, but it also ensures safety and stability during the lifting process. This allows workers to quickly and safely complete lifting tasks in various locations, significantly improving the overall efficiency of mine operations. The guide rails not only provide a path for the pulley 51 but also enhance the stability of the overall structure, ensuring the safe operation of the pneumatic lifting device 5 under heavy loads. This further improves the overall rigidity and stability of the unloading platform, reducing the risk of structural deformation and damage.

[0041] Reference Figure 3As shown, in some embodiments, rollers 11 are provided at the four corners of the bottom of the base 1 to ensure uniform force and stable movement of the unloading platform.

[0042] The installation of rollers 11 allows the unloading platform to be easily moved within the mine, eliminating the need for extensive dragging and significantly improving its flexibility and maneuverability. The design of rollers 11 allows for smooth movement over various types of mine surfaces, whether flat or slightly undulating, enhancing the platform's adaptability. Workers can move the unloading platform with simple push-pull operations, reducing the manpower required during handling and improving work efficiency.

[0043] Reference Figure 3 As shown, in some embodiments, the roller 11 is connected to the base 1 through a telescopic rod 12. The length of the telescopic rod 12 is adjusted as needed to raise or lower the roller 11 to adapt to different operating requirements.

[0044] The design of the telescopic rod 12 allows the height of the roller 11 to be adjusted to adapt to different ground conditions. For example, on uneven ground, the length of the telescopic rod 12 can be adjusted to keep the unloading platform level, ensuring the stability of the operation. The telescopic function allows the unloading platform to be used not only on flat ground, but also on sloped or uneven ground, which increases the applicability of the unloading platform. By adjusting the length of the telescopic rod 12, the mobile mode and fixed mode of the unloading platform can be quickly switched. When it needs to be moved, the roller 11 can be lowered; when it needs to be fixed, the roller 11 can be retracted to keep the unloading platform stably on the ground. By adjusting the telescopic rod 12, it is possible to ensure that the unloading platform remains stable under different ground conditions, avoid the risk of tilting or tipping due to uneven ground, and improve the safety of operations.

[0045] Reference Figure 3 As shown, in some embodiments, the roller 11 is provided with a locking device 13, which is used to lock or unlock the roller 11 through manual operation.

[0046] The design of the locking device 13 allows the roller 11 to be quickly locked and unlocked to adapt to different operating requirements, reducing the preparation time before each operation and improving overall operating efficiency. At the same time, the ability to quickly switch between mobile mode and fixed mode enables the unloading platform to better cope with the changing operating environment in the mine and improve the utilization rate of the unloading platform. The locking function of the locking device 13 ensures the stability of the unloading platform under different operating conditions and avoids the risk of tilting or overturning due to the movement of the unloading platform. This not only improves the safety of the unloading platform, but also extends the service life of the unloading platform. The design of the locking device 13 significantly reduces the physical labor of workers and improves the convenience and comfort of the operation. Workers can quickly lock or unlock the roller 11 through simple operations, reducing the tedious operation of manual adjustment and improving the working environment.

[0047] Reference Figure 4 As shown, in some embodiments, a plurality of pressure sensors 41 are provided on the top beam of the I-frame 4 for monitoring the pressure exerted by the pneumatic lifting device 5 on the I-frame 4 during the lifting process.

[0048] As needed, multiple pressure sensors 41 are installed at various locations on the top beam of the I-beam 4 to comprehensively monitor pressure changes at each location. These sensors monitor the pressure exerted by the lifting equipment on the I-beam 4 during the lifting process in real time, providing accurate pressure data. This helps operators understand the stress on the I-beam 4 and prevent overloading. The pressure sensors 41 record pressure data from each operation, facilitating subsequent analysis and troubleshooting, and providing a basis for maintenance and improvement of the unloading platform.

[0049] Reference Figure 4 As shown, in some embodiments, the pressure sensor 41 is connected to the alarm device 42, and the pressure sensor 41 is connected to the alarm device 42 via a wired or wireless manner to form a complete monitoring and alarm system.

[0050] Pressure sensor 41 monitors the pressure exerted by the pneumatic lifting device 5 on the I-frame 4 during the lifting process in real time and transmits this data to alarm device 42. Once the pressure exceeds a preset threshold, alarm device 42 immediately issues an audible and visual alarm, prompting the operator to take timely action. This real-time monitoring and immediate warning effectively prevent structural damage or safety accidents caused by overload. The combination of pressure sensor 41 and alarm device 42 provides a dual protection mechanism, ensuring timely detection and resolution of abnormal situations.

[0051] Reference Figure 5 As shown, in some embodiments, reinforcing ribs 31 are provided on both sides of the bottom of the gantry 3 to form a stable supporting structure.

[0052] The reinforcement ribs 31 are made of high-strength steel and can be triangular or other geometrically shaped to provide optimal support. The installation of the reinforcement ribs 31 significantly enhances the rigidity of the gantry 3, reduces the risk of deformation under heavy loads, and ensures overall structural stability. The reinforcement ribs 31 effectively disperse stress at the bottom of the gantry 3, preventing structural damage caused by localized excessive stress. The support provided by the reinforcement ribs 31 enables the gantry 3 to withstand greater weight, thereby increasing the load-bearing capacity of the unloading platform.

[0053] Reference Figure 5 As shown, in some embodiments, lighting devices 32 are provided on both sides of the top of the gantry 3 to cover the unloading platform 2 and the surrounding working area.

[0054] The lighting device 32 can be an LED lamp, a halogen lamp, or other high-efficiency lamp. It is waterproof, dustproof, and heat-resistant, making it suitable for the harsh environment of a mine. The lighting device 32 provides sufficient light, allowing workers to work at night or in low-light environments, ensuring the continuity and efficiency of operations. The lighting device 32 is installed on both sides of the top of the gantry 3, covering the unloading platform 2 and the surrounding work area, ensuring effective lighting for the entire work area and reducing dark areas and blind spots. Adequate lighting can reduce accidents caused by poor visibility and ensure the safety of workers during operations.

[0055] According to the above technical features, the working principle of the mobile unloading platform for the tunneling working face provided by this application in actual application scenarios is as follows:

[0056] Workers can easily move the unloading platform to the designated position using rollers 11. The telescopic rod 12 adjusts the height of rollers 11 according to ground conditions, ensuring the stability and levelness of the unloading platform. Once the platform reaches the designated position, the locking device 13 locks the rollers 11 to ensure stability during operation. Workers place materials on the unloading platform 2 and use the flat, spacious work area for loading, unloading, and stacking. Lifting operations are performed using a pneumatic lifting device 5. Pulleys 51 slide along the side beams of the I-frame 4. Pneumatic lifting chains 52 provide stable lifting support. Pneumatic hoists 53 use compressed air to lift and lower materials. Hooks 54 ensure the safety and stability of the materials. Pressure sensors 41 monitor the pressure exerted by the pneumatic lifting device 5 on the I-frame 4 during lifting, providing accurate pressure data in real time. If the pressure exceeds a preset threshold, the alarm device 42 immediately emits an audible and visual alarm, alerting the operator to take timely action to avoid overloading. The lighting device 32 provides ample light at night or in low-light environments, ensuring worker safety and visibility during operations.
