Description

Technical Field

[0001] This utility model belongs to the technical field of mine fire protection, and specifically relates to a fire protection pipeline installed on a belt conveyor. Background Technology

[0002] According to the regulations on coal mine safety, mines must be equipped with surface fire water tanks and underground fire pipeline systems. The underground fire pipelines should be laid to the mining face, and branch pipes and valves should be installed every 50 meters in the belt conveyor roadway to ensure the functions of fire extinguishing, dust suppression and cooling in the event of a mine fire.

[0003] Existing underground fire protection piping systems are mostly laid along the roadway walls or roof. However, in some roadways that also serve as coal transport and auxiliary transport routes, there are problems such as dense personnel and equipment traffic and limited space. To avoid collisions between transport vehicles or personnel and the piping, the main pipeline is usually laid on the non-pedestrian side of the roadway, while a certain length of steel braided pipe is installed at the tee points to extend to the pedestrian side for emergency use or daily operation. Especially in high-extraction mines, according to the standard of installing branch pipes and valves every 50 meters, steel braided hoses are frequently used for cross-side connections, resulting in large material consumption and significantly increased costs. In addition, traditional piping methods rely heavily on pipeline support and fixing structures, have complex installation processes, poor pipeline stability, and inconvenient maintenance, affecting the long-term operation of the system. Therefore, there is an urgent need for a fire protection piping layout method that is structurally stable, easy to install, easy to maintain, and economically superior, to meet the requirements of current safety regulations and optimize the configuration of existing mine fire protection systems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a fire protection pipeline installed on a belt conveyor.

[0005] The technical solution adopted by this utility model is a fire protection pipeline installed on a belt conveyor, including a main fire protection pipeline and branch fire protection pipelines. The main fire protection pipeline is arranged on the non-pedestrian side of the alley, and the branch fire protection pipelines are fixedly installed at intervals above the belt conveyor. A first valve is installed at the pedestrian side end of the branch fire protection pipeline, and a reducing joint is installed at the non-pedestrian side end. The other end of the reducing joint is connected to a steel braided pipe. T-joints are arranged at intervals on the main fire protection pipeline, and a second valve is installed on the t-joint. The second valve is connected to the other end of the steel braided pipe.

[0006] Furthermore, a fixing seat is fixedly installed on the belt conveyor. The fixing seat is U-shaped and fastens to the crossbeams on both sides of the belt conveyor. The fixing seat is fastened to the crossbeams of the belt conveyor by fasteners. The fire protection pipeline is connected to the belt conveyor through the fixing seat.

[0007] Furthermore, a support rod is installed at the upper end of the fixed base, and the upper end of the support rod is connected to the fire-fighting pipeline.

[0008] Furthermore, the fire protection pipeline includes an upper horizontal pipe, with vertical pipes at both ends of the horizontal pipe connecting to the horizontal pipe, and the lower end of the vertical pipe is sealed and fixed to a mounting base.

[0009] Furthermore, the fire-fighting pipeline uses φ50 steel pipes.

[0010] The fire-fighting pipeline installed on a belt conveyor provided by this utility model has the following beneficial effects:

[0011] 1. By installing the branch fire-fighting pipeline on the belt support structure, the original support system is fully utilized, the workload of installing additional brackets is reduced, the construction process is simplified, the structural design is reasonable, the installation is convenient, and the installation efficiency is improved.

[0012] 2. After the branch pipe is arranged on the belt frame, it can be connected to the operating side nearby, which significantly shortens the crossing length, reduces the dependence on steel braided hose, and reduces the overall material and maintenance costs.

[0013] 3. The fixed base and support rod connection method is adopted to ensure that the fire branch pipe is stable and reliable during operation, and to avoid the pipe loosening or damage caused by external forces such as vibration and collision.

[0014] 4. The branch pipe outlet is located on the pedestrian side of the roadway, which facilitates the quick operation of the valve by the operators, enabling timely response and handling in the early stage of a fire. This improves the convenience and safety of operation and meets the emergency response requirements of coal mines.

[0015] 4. By making reasonable use of the space above or on both sides of the belt conveyor, the main passage area of ​​the roadway is avoided. It is especially suitable for the fire protection system layout of the main or auxiliary transport roadway in the mine. It can be adapted to belt conveyors of different types and sizes, which is conducive to the unified implementation and maintenance of coal mining enterprises in multiple working faces and improves the overall operating efficiency of the system.
