Structure and method for auxiliary traction of carrying cables across the river by trolley of cable machine

Abstract

The invention discloses a river-crossing structure for auxiliary traction of a carrying cable by a trolley of a cable machine. It includes a traction system, a connection system, a cable machine traveling trolley, and a lifting traction rope; the traction system includes a cable machine traveling trolley, a reciprocating rope, a load-bearing rope hoist, a reciprocating rope hoist on the releasing side, a reciprocating rope hoist on the non-releasing side, curved rails, guide wheel; the connection system includes rope clamps, filled steel wires, anchoring devices, and hoisting traction ropes; the hoisting traction ropes connect the carrying ropes and the trolley of the cable machine; The cable hoist releases the rope, the reciprocating rope hoist on the non-releasing side takes in the rope, and the cable hoist trolley moves to the non-releasing side under the drive of the traction mechanism. It overcomes the disadvantages of low efficiency, long construction period and potential safety hazards in the existing technology; it has the advantages of short construction period, stable traction process, high economic benefit and high safety factor for crossing the river. The invention also discloses a method for assisting the traction of the carrying cable by the trolley of the cable machine to cross the river.

Description

technical field [0001] The invention relates to the field of cable machine dismantling, more specifically, it is a structure for auxiliary pulling of a carrying cable across a river by a trolley of a cable machine. The invention also relates to a method for assisting the traction of the carrying cable by the trolley of the cable machine to cross the river. Background technique [0002] The cable crane is one of the most commonly used construction equipment in hydropower projects. The dismantling process is difficult and dangerous, and must be carried out carefully. Temporary bearing cables crossing the river are the key links in the dismantling process of the cable crane; the traditional method of carrying cables across the river It is rolled into the hoist on the release side, released through the guide wheel or curved track, connected firmly with the arranged reciprocating rope through the rope clamp, and used the reciprocating rope winch on the non-release side to pull th...

[0002] The cable crane is one of the most commonly used construction equipment in hydropower projects. The dismantling process is difficult and dangerous, and must be carried out carefully. Temporary bearing cables crossing the river are the key links in the dismantling process of the cable crane; the traditional method of carrying cables across the river It is rolled into the hoist on the release side, released through the guide wheel or curved track, connected firmly with the arranged reciprocating rope through the rope clamp, and used the reciprocating rope winch on the non-release side to pull the load-bearing cable across the river; this method mainly relies on the two sides The winch does work to complete the traction, but because the traction force of the winch is limited and part of the work is used to overcome the gravity of the rope, the work efficiency is low, and the time for the load-bearing cable to cross the river is long; At the same time, the load-carrying cable has a large sag in the process of crossing the river, which poses a threat to the safety of the buildings below. Therefore, the traditional method of using reciprocating ropes to pull the load-carrying cable across the river has certain defects

[0003] In the method of temporary load-bearing cables crossing the river commonly used in domestic projects, the traction of the load-bearing cables mainly depends on the work of the winches on both sides to provide power. low, which leads to a long time for the load-bearing cable to cross the river; the reciprocating rope is stressed during the traction process and generates rotation, which is easy to be entangled and twisted with the load-bearing cable, and it is difficult to separate the load-bearing cable from the reciprocating rope after crossing the river; During the process of the river, only the cable ends at both ends are supported and the span is large, forming a large sag under the action of self-weight and load, which poses a safety threat to the buildings below; The safety factor of crossing the river is low
