Description

A replacement system for the overall unloading system at the top of a silo and its construction method

Technical field

The invention belongs to the technical field of discharge system replacement, and more specifically, relates to an integral discharge system replacement system at the top of a silo and its construction method.

Background technique

The belt conveyor unloading trolley is a kind of unloading device. It has the performance of unloading at any point, multi-point unloading, fixed-point unloading, and single and double-side unloading in the horizontal section of the belt conveyor. It is often widely used together with silos. In mining, electric power, metallurgy, coal, building materials and other industries, it is especially suitable for storing raw materials in raw material yards in the metallurgical industry. On the one hand, it facilitates overall distribution and can maximize the use of the site to accumulate materials or distribute materials, thereby saving land; on the other hand, the silo has The environmental protection concept of "first in, first out" for materials and the true realization of "separation of people and materials". However, in the process of long-term use, the structures such as the trolley, track, and bracket in the unloading system will inevitably suffer from equipment wear, and the entire system needs to be shut down for replacement. Shutdown and replacement have a particularly great impact on production and loading, especially for In the metallurgical industry, production capacity has been greatly reduced, so the construction period for unloading trolleys to be shut down and replaced with new ones is particularly stringent. Therefore, proposing a fast and efficient method for replacing the unloading system is of great significance to the entire maintenance cycle.

In order to solve the above technical problems, Chinese invention patent CN115724147A discloses an installation method of an annular feeder, which includes the following steps: Step 1, install the inner ring unloading car track and the inner ring plow car track; Step 2, install the inner ring Plow truck and driving device; Step 3, install the inner ring unloading truck and driving device; Step 4, install the inner ring unloading device; Step 5, install the inner ring plow truck sealing device; Step 6, Inner ring unloading truck Sealing device; Step 7, install the outer ring equipment; Step 8, install the electrical system equipment and debug, optimize the construction sequence, shorten the installation time of the equipment, achieve the purpose of saving the construction period, and improve the installation efficiency and installation quality of the equipment. Ensure the smooth operation of the equipment; in addition, the Chinese utility model patent CN216286206U discloses a coal storage and unloading trolley control device, vehicle control cabinet, on-board camera, unloading trolley motor, limit switch, antenna box, Gray busbar, radar material level meter, ground control cabinet, central control room and ground cameras. The frequency converter control method is adopted to prevent the unloading trolley from shifting, and Gray busbar, radar level meter, address encoder, etc. are used to monitor the running position of the unloading trolley in real time to ensure the precise positioning of the unloading trolley. At the same time, each The camera at the location transmits the monitoring image to the central control in real time, allowing the operator to observe the on-site working status more intuitively. A coal storage and unloading trolley control device has higher overall automation, informatization level and safety performance, which not only ensures safe production, but also improves production efficiency.

However, there are the following improvements in the above-mentioned patented technology: (1) The operating environment space of the unloading trolley at the top of the silo is small, so only a few components can be hoisted to the platform in advance through the original hoisting holes on the roof, and the unloading The main structure of the trolley is huge. After disassembly, it will bring a lot of assembly and transport workload to the site. Therefore, it is difficult to meet the construction period requirements by disassembling and reinstalling the unloading trolley using conventional methods; (2) Due to the horizontality and linearity of the track installation The degree of friction greatly determines the friction coefficient during the operation of the unloading system, so measures should be taken to improve the effectiveness of rail segment connection; (3) Improving rail linearity should start from the installation of rail segments and the installation of completed rail segments. Starting from the angle of overlap between postures, it can effectively improve the rail connection quality.
