Description

Technical Field

[0001] This invention belongs to the field of unloading system replacement technology, and more specifically, relates to an overall unloading system replacement system for the top of a silo and its construction method. Background Technology

[0002] The unloading trolley of a belt conveyor is a type of unloading device, capable of unloading at any point on the horizontal section of the belt conveyor, multiple points, fixed points, and single or double sides. It is often used in conjunction with silos in industries such as mining, power, metallurgy, coal, and building materials, and is particularly suitable for storing raw materials in metallurgical raw material yards. On the one hand, it facilitates overall material distribution, maximizing the use of space for material storage or distribution, thus saving land; on the other hand, silos embody the "first-in, first-out" principle and truly achieve the environmentally friendly concept of "separation of personnel and materials." However, during long-term use, the trolley, tracks, supports, and other structures in the unloading system inevitably experience wear and tear, requiring complete shutdown and replacement. This shutdown and replacement has a significant impact on production, especially in the metallurgical industry, drastically reducing capacity. Therefore, the construction period for unloading trolley replacement is particularly stringent. Thus, proposing a rapid and efficient method for replacing the unloading system is of great significance for the entire maintenance cycle.

[0003] To address the aforementioned technical problems, Chinese invention patent CN115724147A discloses an installation method for a ring feeder, comprising the following steps: Step 1, installing the inner ring unloading car track and the inner ring plow car track; Step 2, installing the inner ring plow car and its drive device; Step 3, installing the inner ring unloading car and its drive device; Step 4, installing the inner ring unloading device; Step 5, installing the inner ring plow car sealing device; Step 6, installing the inner ring unloading car sealing device; Step 7, installing the outer ring equipment; Step 8, installing and debugging the electrical system equipment. This method optimizes the construction sequence, shortens the equipment installation time, achieves the goal of saving construction time, improves the installation efficiency and quality of the equipment, and ensures stable operation of the equipment. Furthermore, Chinese utility model patent CN216286206U discloses a control device for a coal storage unloading trolley, comprising an onboard control cabinet, an onboard camera, an unloading trolley motor, limit switches, an antenna box, a Gray busbar, a radar level gauge, a ground control cabinet, a central control room, and a ground camera. The system employs frequency converter control to prevent displacement of the unloading trolley. Gray busbars, radar level gauges, and address encoders are used to monitor the trolley's position in real time, ensuring precise positioning. Simultaneously, cameras at each location transmit monitoring images to the central control unit in real time, allowing operators to more intuitively observe the on-site working status. This coal storage unloading trolley control device boasts higher levels of automation, informatization, and safety, ensuring safe production while also improving production efficiency.

[0004] However, the above-mentioned patented technologies have the following improvements: (1) The operating environment of the unloading trolley at the top of the silo is small, so only a very small number of components can be hoisted to the platform in advance through the original hoisting holes on the roof. The main structure of the unloading trolley is huge, and disassembly will bring a lot of assembly and transportation work to the site. Therefore, it is difficult to meet the requirements of the construction period by disassembling and reinstalling the unloading trolley using conventional methods; (2) Since the levelness and linearity of the track installation largely determine the friction coefficient during the operation of the unloading system, measures should be taken to improve the effectiveness of the connection of the track segments; (3) Improving the linearity of the rail should start from the perspective of the coincidence of the posture between the installed track segments and the completed track segments, so as to effectively improve the quality of the rail connection. Summary of the Invention

Furthermore, the newly installed unloading trolley can be directly hoisted onto the tracks and transported into the silo for rapid replacement.

[0051] 1. The present invention provides a silo top integrated unloading system replacement system. By opening a doorway in the side wall of the plant and erecting a steel frame, an auxiliary unloading trolley frame, and an auxiliary track outside the plant, the system not only achieves spatial and temporal separation between the unloading trolley inside the plant and the auxiliary unloading system replacement system outside the plant, ensuring that the two do not interfere with each other, but also enables rapid replacement by directly hoisting the newly installed unloading trolley onto the track and transporting it into the silo. This effectively avoids the disassembly of the unloading trolley and the handling and assembly within the confined space inside the silo, thereby greatly shortening the installation period of the unloading trolley body and improving the installation quality and construction safety of the equipment.

The silo top integral unloading system replacement system of the present invention can extend the old belt to the track of the auxiliary unloading trolley by adjusting the old belt conveyor counterweight, and use hoisting equipment in conjunction with the original belt conveyor to transport the auxiliary components of the unloading trolley, thereby avoiding manual handling of materials from the structural hoisting holes to the installation position, saving a lot of manpower and improving the efficiency of material handling.

[0053] 3. The present invention provides a silo top integrated unloading system replacement system, which allows the newly replaced unloading trolley to be installed from the tail pulley of the belt conveyor, while the original unloading trolley is removed and transported out from the head pulley.
