Description

TECHNICAL FIELD

The present invention relates to a technology of erecting a temporary ropeway bridge and a necessary engineering equipment assembly, and specifically to a steel rope ropeway composed of a wire rope suspension structure, acting as a temporary bridge for transporting heavy vehicle equipment and having an explosion-proof function.

BACKGROUND OF THE INVENTION

The main role of a bridge is to make personnel, vehicles and heavy equipment across a section of areas that cannot pass normally, such as rivers, valleys and other naturally formed obstacles, and the buildings are set up on rivers, lakes, seas, mountains and valleys, so that vehicles and pedestrians can pass smoothly. A complete bridge, the basic components of the bridge span part, pier part, support part, abutment part, pier and foundation composition, these are the most basic components, it can be said that without these several parts of the bridge is not a complete bridge. Construction of such a 100 meters long, 50 tons of bridge, at least a year, generally this kind of bridge are fixed position, public exposure, long use, impossible to remove or change position, no concealment, if there is explosives into a bridge from the air, it is easy to hit any part of the bridge, and repair the bridge needs a long time, also can't guarantee safety. Therefore, how to avoid the occurrence of these adverse conditions, to ensure that a large number of personnel and equipment can surprise smoothly through between the valley without a bridge, therefore developed a single wire rope combination winch, portable stake, positioning pile, simple ropeway bridge, with simple operation, anytime, anywhere, convenient, convenient to use, high concealment, not easy to find, difficult to destroy.

SUMMARY OF THE INVENTION

In order to mountain channel for person, vehicles and other equipment passing between canyon in very short time, the present invention provided a device and method structure to erect temporary explosion-proof suspended ropeway bridge, the structure has a convenient conditions for convenient installation, anytime, easy operation, fast time saving, less auxiliary erection equipment, only two people can installed in a very short time, and good concealment, flexible structure, not easy to find or destroy, to achieve the purpose of passing through many personnel and equipment in a state of emergency
To achieve the above purpose, the present invention is a temporary explosion-proof suspended ropeway bridge. The installation method is, when the personnel and vehicle equipment to the valley side, First, build a guide rope path that can transport people and light tools and equipment to the other side, two men then carried portable stakes ( PCT / CN2018 / 081654 ) and tools to the opposite side of the canyon by using guide ropes, After the installation of portable stakes, people from both sides cooperate to set up a heavy wire rope ropeway, install a crane pulley, and they can transport vehicles and other equipment through the canyon.
Further, the one end of the guide rope is attached with a barbed anchor hook. Further, the anchor hook with a gun thrust is fired through the small rocket to the other side of the area.
Further, personnel, portable stakes, tools, and other spare parts are transported to the other side by the guide rope.
Further, people transported by the guide rope are dressed in foam or airbag type or other styles of protective clothing.
Further, the guide rope adopts the industrial standard, the most commonly used is the safety rope for the fire fighter, the selected model to meet the weight of all the portable stake components transported at a time.
Further, the steel wire rope for forming the ropeway bridge uses the steel core steel wire rope.
Further, the wire rope can be painted with camouflage of the same color as the surrounding scenery.
Further, the nominal tensile strength of the wire rope is greater than 2,000MPa.
Further, the wire rope nominal diameter is determined according to the maximum weight of the equipment in a single transport vehicle.
Further, the ropeway bridge wire rope has a manual chain unwinding device, which can apply tension or relaxation of the steel rope to adjust the steel rope sag as required.
Further, Install a crane point slide on the steel rope ropeway, which moves forward or backward along the steel rope ropeway to form a ropeway bridge transporting personnel and equipment.
Further, in order to make the lifting point on the wire rope moving more stable safety, using longitudinal layout of more than two pulley , flexible ropes are attached to the front and rear of the pulley, The two ends of the rope are connected to the small deceleration winch, dragging the pulley back and forth to achieve the effect of transporting the vehicle equipment, the winch can be manual or electric or various small engines
Further, the flexible rope of the towing point pulley movement can be connected to the pulley or directly to the transported vehicle equipment, as determined based on the site situation.
Further, a winch one-directional braking supporting positioning pile device is generally used when fixing the winch
Further, according to the site geological terrain situation, the portable stake of the fixed steel wire rope can be replaced by a winch one-directional braking supporting positioning pile device.
The beneficial effects achieved by the present invention are:
The present invention proposes a ropeway bridge with little equipment demand, a simple, fast and convenient erection process, and is based on a single wire rope, can be erected anytime and anywhere, high concealment, not easy to destroy, when the personnel and equipment through, can be immediately removed, to achieve the unexpected, unpredictable, unimaginable and other bridges that do not feature during construction and use.
The present invention uses a temporary explosion-proof suspended ropeway bridge composed by a single wire rope, a winch winding the wire rope and a portable stake (pct / cn2018 / 081654), reasonable structure, simple operation, no difficulty, the erection and disassembly process is time-saving and convenient. Steel rope ropeway has only a few couplings with winches and portable stakes, which are standard industrial parts. Through practical verification, the theoretical bearing capacity can be shown and proved, ensuring the reliable safety and stability in practical use.
