Railway transport has a large volume, long distance reasonable, low-cost, reliable production, equipment and spare parts easy to solve, etc., so widely used in China's large open pit rail transport. Common accidents in railway transportation include accidents such as crashes, derailments, and crossings. In addition to illegal dispatching and illegal operation, the occurrence of these accidents is due to equipment disrepair, line bending and sinking, and the increase of gauge distance. The off-road accidents (both on both sides of the railway and unstable loading lead to moving ore) Falling off, hurting, overweight, heavy, etc.), unattended or safe signal at the level crossing of railways and highways, failure of the barrier, and running trains that do not have "full wind brake". In the safety device and safe operation of rolling stock, it is required to have a brake on each locomotive. In addition to the "single machine brake", there should be a "train brake" that the driver uses to adjust the train speed or take safety measures when parking. Each vehicle should be equipped with a car ladder and pedals, good front and rear lighting, and signals. Signage lights, whistle and bagpipe audible signals and safety devices such as door locks in the motor room, high pressure room or auxiliary room door. In the safety of shunting operations, special attention should be paid to the safety protection during vehicle pick-up operations. When picking up the car, park the vehicle on more than 0.25% of the ramp to do the anti-slip measures, and then pick up the car. Prevent the sinking of the track line and set up the necessary "dead fork rail". There should be a pedestrian path on the side of the railway line, a "careful train" street sign in the place where the route is crossed, and night lights and various signal lights in the open pit mine. Railway transport personnel should strengthen safety and joint defense, have the right to stop all illegal operations, and report the hidden dangers of accidents immediately and urge them to make timely corrections.
Flexible lift gate is a flexibel soft curtain door, inside and outside the two curtains , curtains used between the aluminum beams connected with a vertically movable rail , the roof beams have levels not in the same straight line and hanger large plants in particular Be applicable , Flexible lift door installation does not take up interior space in the hole inside , When the first move to open the door , and finally superimposed over the hole , Off event curtain rail first and then fall down until its is completely closed
Door body composition :
The bottom of the door curtain rail aluminum beam beam seal top drive system and transmission of electrical control systems and safety devices
Flexible door features:
1. Light weight compared with other types of the same size door , flexible door lighter weight reduces the strength of steel at the top of the doorway architecture degree requirements ,
2. Small compared with the same specification of the machine style doors 2, footprint ,flexible installation in the door after the hole is turned on internally stacked above the hole , do not take up interior space , Large Span hole may be provided a plurality of movable rail the entire door into several independent stacking doors shorten the span of a single door so that the overall thickness of the door is reduced , further reducing the footprint
3. Rational layout flexible doors with movable rail rail can set different activities based on the specific circumstances of the door into the door several sizes of uneven accumulation of doors to make the building as a whole rational layout greatly reduces the overall architecture of the space and cost
4. The wind strength between two layers of high flexible door curtain as the bottom of an aluminum beam has a wind skeleton steel structure , By adjusting the beam thickness and spacing , which can resist wind pressure of any intensity , so the door can be flexible for use in any area
5. The tensile strength of the flexible door after door curtain is double polyester fabric , high tensile wire rope equipped with ultra-high hole suitable for large machinery such as aircraft hangars and repository
6. The curtain coated with vinyl coated with a waterproof sunscreen and smoldering performance , capable of sound absorption retardant insulation mildew proof and so on
7. Safe door , Cube with anti-lock break to ensure safety in case of accidental breakage of wire rope jammed in the door quickly experience anywhere rails , Multiple protection features mechanical and electrical installation to ensure t he safety of goods passing aircraft and other vehicles and personnel , the movable rail is also equipped with anti-fall device , you can ensure reliable parked at the top of the hole after the movable rail is raised without falling , The bottom of the door is equipped with and airbag , it will immediately rebound to rise until the safety door drops open when obstacles encountered in the process , You can also install infrared protection device on the door
