Description

Technical Field

[0001] The invention relates to the technical field of granulating covers, in particular to a movable cover. Background Art

[0002] As the country's environmental protection requirements continue to increase, various industries have taken measures to carry out refined management. As part of the traditional heavy industry, the steel industry faces many challenges in environmental protection upgrades. Many steel mills need to renovate or build new workshops to meet new environmental standards. However, some existing problems hinder the effective implementation of these improvement measures:

[0003] The original workshop height is limited: When upgrading and renovating the original factory building, the height limit of the workshop becomes an important constraint. This limitation not only affects the selection and installation of equipment, but also limits the working range of the overhead crane (i.e. bridge crane).

[0004] Limited space reserved for new plants: Even in the case of newly built plants, due to planning and cost considerations, there is often insufficient operating space for overhead cranes, resulting in their working range being unable to fully meet production needs.

[0005] Large human resource investment: The above two problems directly lead to excessive reliance on human resources. In order to make up for the inconvenience of operating mechanical equipment, enterprises have to increase human resource investment, which not only increases operating costs, but also has a negative impact on production efficiency.

[0006] Problems with the working environment and field of vision of the crane operator: During aerial work, the crane operator needs to pay attention to the granulation area (which may refer to a specific area in the steelmaking process) and the dynamics of the ground staff at all times to ensure safe operation. However, the existing crane design and layout often cannot provide the best field of vision, which brings additional operating difficulties and safety hazards to the crane operator.

[0007] Based on these problems, an innovative solution - mobile cover - was proposed. This invention aims to improve the working environment of the crane driver and expand his field of vision through a new design, while overcoming the problems of limited height of the original plant and insufficient space in the new plant, thereby improving work efficiency, reducing human resource investment, and enhancing work safety. This solution is not only suitable for the steel industry, but also has important reference value for other industries with similar problems. Summary of the invention

[0036] Figure 1 FIG. 1 is a schematic diagram of the structure of the movable cover according to an embodiment of the present invention. Figure 1As shown, an embodiment of the present invention relates to a mobile cover for a granulation cover, and the mobile cover comprises: a driving mechanism 1, a walking assembly 2, a cover body 3, a buffer assembly 4 and a limit assembly 5.

[0038] In summary, the mobile cover solution provided by the embodiment of the present invention not only realizes efficient and automated management of the tipping area of ​​the granulation cover, but also further enhances the safety, reliability and durability of the system by introducing a buffer component and a limit component. In addition, the need for manual intervention is reduced, and the overall work efficiency and environmental protection level are improved.

[0039] Figure 2 Schematic diagram of the structure of the driving mechanism and the walking assembly of the embodiment of the present invention. Figure 2The driving mechanism 1 includes a supporting frame 1-1, a driving motor 1-2 fixed to the supporting frame 1-1, and a transmission mechanism 1-3 drivingly connected to the output shaft of the driving motor 1-2; the transmission mechanism 1-3 is drivingly connected to the walking component 2. The walking component 2 includes a transmission shaft 2-1 and a walking wheel 2-2 drivingly connected to the transmission shaft 2-1, and the transmission shaft 2-1 is drivingly connected to the transmission mechanism 1-3.

[0040] In some embodiments, the walking assembly 2 also includes a connecting shaft 2-3, and the connecting shaft 2-3 is fixedly connected to the transmission shaft 2-1.

[0041] Specifically, Figure 2 As shown, the transmission mechanism 1-3 includes a driving wheel arranged on the output shaft of the driving motor 1-2, and a driven wheel arranged on the connecting shaft 2-3 and drivingly connected to the driving wheel. In some embodiments, the driving wheel is a driving sprocket, the driven wheel is a driven sprocket, and the transmission mechanism also includes a transmission chain drivingly connected to the driving sprocket and the driven sprocket respectively.

[0042] Specifically, Figure 2 As shown, in this embodiment, the transmission adopts a steel pipe as the transmission shaft 2-1, and a connecting shaft 2-3 is added in the middle of the transmission shafts 2-1 on both sides. A sprocket is added to the connecting shaft 2-3, which is connected to the driving sprocket of the driving motor 1-2 through a chain transmission, and the other end of the transmission shaft 2-1 is a walking wheel 2-2.

[0043] In some embodiments, Figure 2 As shown, the driving mechanism 1 also includes a reducer (not numbered in the figure), the output shaft of the driving motor 1-2 is drivingly connected to the input shaft of the reducer, and the output shaft of the reducer is drivingly connected to the driving sprocket.

[0044] Figure 3 Schematic diagram of the cover structure of an embodiment of the present invention. Figure 3 The cover body 3 includes a front baffle plate 3-1, a top side plate 3-3, a side baffle plate 3-2 respectively connected to the front baffle plate 3-1 and the top side plate 3-3, and a sealing plate 3-4 respectively connected to the top side plate 3-3 and the side baffle plate 3-2 for sealing the granulation cover.

[0045] The mobile cover of the embodiment of the present invention can effectively cover the granulation cover through the combined use of the front baffle, the top side plate and the side baffle, provide all-round protection and prevent the spread of dust and other pollutants. The sealing plate is connected to the top side plate and the side baffle to further seal the granulation cover. This design can effectively reduce the leakage of particulate matter, improve the environmental protection effect, and help maintain the cleanliness of the operating environment. The connection method between the components (such as bolt connection or welding) enhances the stability of the entire cover structure, so that it can withstand certain external pressure and impact, and ensures the reliability of long-term use. The modular design is easy to install and disassemble, making it more convenient and quick when maintenance or replacement of components is required. For example, if a component is damaged, only the component needs to be replaced without large-scale changes to the entire system. In addition, the size and material selection of each baffle can be adjusted according to actual needs to adapt to different working environments and conditions. For example, in a high temperature or corrosive environment, a high temperature resistant or corrosion-resistant material can be selected to make the baffle. Finally, since the side baffle is connected to the front baffle and the top side plate at the same time, such a design provides good flexibility, allowing a certain degree of adjustment to adapt to irregular spaces or equipment shapes.

[0046] In summary, this hood design not only improves work efficiency, but also enhances safety, reliability and environmental protection performance, providing an effective solution for particulate matter control in industrial production processes.

[0047] Figure 4 FIG. 1 is a schematic diagram of the structure of a buffer assembly according to an embodiment of the present invention. Figure 4 The buffer assembly 4 includes a support 4-1 and a buffer block 4-2 arranged on the support 4-1.

[0048] In the movable cover of the embodiment of the present invention, the support can provide a solid installation foundation for the buffer block, ensuring that it can remain stable without displacement when impacted. The support can also be customized according to the actual application scenario, and suitable materials and structures can be selected to meet different requirements of mechanical strength, corrosion resistance, etc. In addition, the support is usually designed with a convenient installation interface, so that the entire buffer assembly can be quickly and accurately installed in place, and the position can be easily adjusted when necessary. The buffer block can be made of a material with excellent elasticity and energy absorption properties (such as rubber, polyurethane or spring, etc.), which can absorb and disperse the impact energy when the cover body contacts the granulation cover body or other surfaces, thereby reducing vibration transmission. By alleviating the collision force, the buffer block effectively protects the cover body and other related equipment from damage, thereby extending the service life of the equipment. The buffer block can not only absorb mechanical shocks, but also reduce the noise generated by hard contact, thereby improving the quality of the working environment.

[0049] In summary, the mobile cover of the embodiment of the present invention adopts a buffer assembly design consisting of a support and a buffer block, which not only enhances the safety and reliability of equipment operation, but also improves the overall work efficiency and user satisfaction through effective vibration absorption and noise control. In addition, it also has good adaptability and flexibility, and can be optimized and configured according to the requirements of different application scenarios.

[0050] Figure 5 Schematic diagram of the structure of the limit assembly of the embodiment of the present invention. Figure 5 The limit assembly 5 includes a paddle 5-1, a bracket 5-3, and a travel switch 5-2 arranged on the bracket 5-3. The paddle 5-1 is arranged on the walking assembly 2 and corresponds to the travel switch 5-2.

[0051] In the movable cover of the embodiment of the present invention, the paddle is directly installed on the traveling assembly, and can move with the movement of the traveling assembly, and accurately trigger the travel switch at a specific position, thereby ensuring the accuracy of the operation. The shape and size of the paddle can be adjusted according to actual needs to adapt to different mechanical structures and working environments. In addition, the bracket provides a solid support for the travel switch to ensure that it will not be offset or damaged when touched by the paddle, thereby increasing the reliability of the entire limit system. The bracket design usually takes into account a variety of installation methods, so that the travel switch can be easily installed in the best position to achieve the most effective monitoring. Finally, the travel switch can respond quickly at the moment of contact with the paddle, providing an immediate position feedback signal for controlling the movement of the traveling assembly.

[0052] In summary, the movable cover and the limit assembly of the embodiment of the present invention not only improve the safety and control accuracy of the equipment by cleverly combining the paddle, the bracket and the travel switch, but also effectively reduce the operating cost due to its simple structure and easy maintenance. This design is very suitable for various mechanical equipment that requires precise limit control.

[0053] In some embodiments, the mobile cover also includes a maintenance platform to perform maintenance on the mobile cover. The maintenance platform generally includes a carrier and some maintenance tools arranged on the carrier, such as manual maintenance tools and electric maintenance tools, etc., which are not limited in the embodiments of the present invention.
