[brief]
it is mainly composed of the troughs and the running parts of the transporter, and is driven by the traction electric locomotive on the track. the car body is set on two bogies, and there is a scraper or chain plate conveyer on the floor of the carriage. it is driven by wind or electric power, and there is also a dual purpose wind power, and the electric drive is generally used.
the mineral debris is loaded from the ballast end of the carriage, and the continuous rotating scraper or chain plate conveyer automatically reloads the slag from the ore material to the unloading end; to be filled with the whole shuttle, the traction motor vehicle is traced to the unloading field, and then the conveyer can be unloaded safely and reliably, and the rock debris can be discharged automatically.
shuttle cars can be used for bicycles, and can also be used to form shuttle trains running by several series of lapping. with the shuttle car replacing the fighting car with the ballast, the blasting volume can be completely installed in one time, in order to reduce the shunting and ballast time, to reduce the time of shunting and ballast, and to speed up the tunnel driving speed.
the shuttle miner has basically integrated the flexibility and simple structure of the wagon and van type miner; it has the advantages of large volume, continuous reloading and automatic unloading. it can be operated on a 12~15 meter small radius bend, and it can be unloaded on the front end of the unloading line without laying a rack, and can safely discharge ballastballast to both sides, so that the unloading is not discarded. the limits of the site. therefore, shuttle cars are widely used in the excavation of mine laneways around the world, and are often used in the construction of tunnels and underground works. the domestic shuttle model products are divided into small shuttle miner and large shuttle miner. the volume is 4, 6, 8, 10, 12, 14, 16, 20, 25, 30 and 45 cubic meters. according to the construction characteristics and requirements of railway tunnels and highway tunnels, it is necessary to develop a single large capacity shuttle car and use traction electric locomotive to pull on the track. jiangxi pingxiang yan ding technology has developed a shuttle car volume up to 45 cubic meters.
the use of the shuttle car instead of the fighting car and the van type miner to pick up the ballast can reduce the shunting and ballast time, speed up the tunnel driving speed, and naturally reduce the driving cost. the advantages of the shuttle miner are: fast unloading speed, large volume storage, high efficiency of unloading the car, no bottom of ore and slag, unfouling laneway, unrestricted ore block, flexible and convenient use, high reliability of equipment and so on. it is a small dumper truck and side dump truck, because of its small storage and combination of the form of train type. it is the most advanced transportation mine, which is the most advanced transportation mine, and has a simple and large storage capacity. if the ore is automatically discharged, a quick and safe equipment can be carried away by a single gun. it is the most suitable transportation tool for construction units such as mine well roadway, diversion tunnel of hydropower station, water diversion tunnel, natural gas transmission pipeline, small mine tunnel, highway, railway tunnel, tunnel and other construction units.
[operating procedures]
1. shunting operators must be trained to be familiar with the performance, structure and principles of shuttle tramcar, and pass the examination and obtain the operation certificate before operation.
before the 2. operation, the iron wedge and various tools should be prepared, and the lubricating parts are lubricated according to the regulations; the bogie, the connecting pin and the traction rod should be carefully checked; the electric shuttle bus should check the damage degree of the cable skin and the humidity of the electrical device, and should be repaired or replaced when it is not stipulated or hinders the safety. construction is not allowed when the state is not normal.
3. the shuttle type tramcar should be operated no-load before loading ballast. the transmission chain and the scraper transport chain should not be relaxed.
4. electric shuttle cars should wear insulating gloves when they are connected to the power supply. after the wind shuttle shuttle is connected to the wind pipe, the tension should be slightly checked to check the joint, and then the machine can be switched on after confirming the reliable.
5. when applying ballast, wedge the front and rear wheels tightly. personnel shall not approach the shuttle car to prevent the shuttle car from being impacted by rock or impact debris. when drivers close to work, they should suspend ballast and prohibit the use of stone slag or wooden strips instead of iron wedges.
6. during the running of the shuttle car, the driver should observe the machine condition at any time. if there is an abnormality, he must stop immediately to check the trouble. it is forbidden to continue to operate without exception when the machine condition is abnormal.
7. when the shuttle car is full, the driver must dismantle the power supply or the wind source and remove the foreign matter on the track before connecting with the battery car. if you confirm that the connection is correct, remove the iron wedge before you send out the driving signal.
8. when unloading ballast, the iron wedge must be wedged in the two directions of the wheel, and no ballast or wood bar should be used to replace the iron wedge. it is confirmed that the unloading direction can be opened in the rear.
in the course of the 9. shuttle bus, people are forbidden to carry them.
10. after the work is finished, the shuttle car should be cleaned, towed to the designated safe place and parked in the two directions of the wheel with iron wedge.
11. shuttle type tramcar can be equipped with slag remover for slag transportation. when the shuttle mine truck reverses to the bottom of the slag scraper, it needs a handy conductor to command at the rear.
