Description
Technical field
The utility model belongs to overhead transmission line construction under tension stringing apparatus field, is specifically related to a kind of traction limp.
Background technology
± 800kV extra-high voltage direct-current demonstration project adopts six-multiple conductor, because conductor cross-section is big, existing hauling machine traction six conductors tractive effort is not enough, and therefore most of unit in charge of construction adopts " 2 * (one leads three) " exhibition to put mode (i.e. two hauling machines carry out " leads three " synchronously open up the mode of putting).Existing " one leads three " pulley block adopts five to take turns layout (4, four guide rollers of a wire rope pulley are symmetrically arranged in the wire rope pulley both sides), only uses wherein three guide rollers 7 during unwrapping wire, 5 balanced actions of surplus next pulley.Because wire rope pulley one side is arranged two leads, opposite side is arranged a lead, so the gravity of lead will cause releasing pulley stressed unbalance; Corresponding traction limp also is that a side is arranged two leads, and opposite side is arranged a lead, is subjected to force unbalance.Therefore general " one leads three " releasing pulley and traction limp are tilted easily, are overturn in the unfolding conductor process, bring very big difficulty to construction.
As shown in Figure 1, general " one leads three " of the prior art traction limp comprises pull rope connecting hole 1, limp body 2, wire connection hole 3, counterweight 4.When the tension stringing initial condition, pull rope connects the pull rope connecting hole 1 that draws limp by the wire rope pulley of releasing pulley, and the wire connection hole 3 of traction limp connects three leads; After tension stringing began, pull rope was along the wire rope pulley traction limp of releasing pulley, and three leads of traction limp traction are opened up forward and put; Along with unfolding conductor, pull rope and traction limp are by releasing pulley, and three leads continue exhibition along three lead pulleys of releasing pulley to be put, and finishes up to unfolding conductor.
Arrange three wire connection holes 3 on the limp body 2 of general " one leads three " traction limp, two are arranged in traction limp left side, the 3rd is arranged in the right side, so traction limp left side is stressed greater than the right side in the lead distraction procedure, and the traction limp is inclination flip to the left; Equally, be used " one leads three " releasing pulley of spreading conducting wire also to be provided with three lead pulleys with the traction limp, two are arranged in the releasing pulley left side, the 3rd is arranged in the releasing pulley right side, three leads are opened up forward when putting by three lead pulleys, the coaster left side is stressed greater than the right side, and coaster will overturn to the left.Existing general " one leads three " traction limp is to realize drawing the limp stress balance by adding a counterweight 4 in the afterbody center of limp body 2, even employing balance weight structure, it is still wayward to want that the releasing pulley that makes the traction limp and be mated use remains stress balance in the spreading conducting wire process, the upset of limp and coaster can appear usually, thereby cause lead to twine, can not continue exhibition and put; In addition, owing to increased counterweight, also improved the production cost of traction limp.
