Problems solved by technology

[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

Abstract

The invention discloses a structure for assisting a traction skyline to cross a river by a cable crane traveling trolley. The structure comprises a traction system, a connection system, the cable crane traveling trolley and a lifting traction rope; the traction system comprises the cable crane traveling trolley, a reciprocating rope, a skyline windlass, an unwinding-side reciprocating rope windlass, a non-unwinding-side reciprocating rope windlass, a bent track and a guiding roller; the connection system comprises a rope clamp, a filling steel wire, an anchor device and the lifting traction rope; the lifting traction rope is connected with the skyline and the cable crane traveling trolley; the unwinding-side reciprocating rope windlass and the skyline windlass reel off ropes, the non-unwinding-side reciprocating rope windlass takes in the rope, and the cable crane traveling trolley moves towards a non-unwinding side under the drive of a traction mechanism. The structure overcomes the disadvantages, i.e., low efficiency, long construction period and potential safety hazards in the prior art and has the advantages of short construction period, stable traction process, high economic benefit and high coefficient of safety of river crossing. The invention further discloses a method for assisting the traction skyline to cross the river by the cable crane traveling trolley.

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.
