Abstract

The invention relates to a rail lifting method of a heavy steel rail. The rail lifting method uses a rail lifting device and a crane in a matched manner to lift up a rail, and particularly comprises the following steps that: in a working process, a lifting hook of the crane uses left and right jaws to tightly clamp a QU80 type rail through steel wire ropes; the lifting hook of the crane lifts up a plurality of the left jaws and the right jaws simultaneously through the steel wire ropes, so that the QU80 type rail with the length of 12 m is lifted up; and then a rail base plate is mounted at the lower part of the QU80 type rail, so that the purpose of leveling the rail or replacing a damaged rail can be realized without entirely dismounting follower bolts of the QU80 type rail. The rail lifting method provided by the invention has the beneficial effects of simple tool manufacturing and convenience in operation; the obvious effects can be reached without large labor; and the maintenance time can be saved; in the condition of not entirely dismounting the follower bolts, the purpose that the base plate is placed under the rail to enable the rail to return back to an original height again or replace the rail is achieved.

Description

A kind of rail lifting method of heavy rail track
Technical field
The present invention relates to a kind of maintenance of equipment method, particularly relate to a kind of rail lifting apparatus and method of gantry crane QU80 type track.
Background technology
In the long-term process of using of gantry crane, because outdoor environment and long-term overladen use, cause track foundation badly damaged, track sink, rail pressing plate is ineffective, and finds in the process of wanting to repair the basis, because of rail pressing plate for a long time under outdoor open-air atmosphere, cause the serious corrosion of follower bolt, remove difficult; Existing method with track levelling or replacing track is: must all pull down QU80 type rail pressing plate bolt first, just can proceed the levelling track or change the operation that damages track.
Summary of the invention
The purpose of this invention is to provide a kind of rail lifting method of heavy rail track, in the situation that do not need follower bolt is all pulled down, can realize backing plate is put under the track, make track come back to the purpose of original height or replacing track.
In order to address the above problem, the present invention by the following technical solutions:
A kind of rail lifting method of heavy rail track, the method adopt rail lifting device and hoisting crane to cooperate track are lifted, and specifically may further comprise the steps:
1) the rail lifting device comprises left jaw, right jaw, ringbolt, steel rope, crane hook, bearing pin screw, and left jaw, right jaw connect by the bearing pin screw, are provided with ringbolt on left jaw, right jaw top; Crane hook is connected with left jaw and right jaw by the suspension ring of steel wire penetrating ringbolt;
2) when work, crane hook utilizes left and right jaw to clamp QU80 type track by steel rope, it is that 12 meters QU80 type track lifts with length that crane hook relies on steel rope to lift by crane simultaneously a plurality of left jaws and right jaw, then at QU80 type track bottom attachment rail backing plate, namely realize not needing QU80 type rail pressing plate bolt is all pulled down, levelling track or replacing damage the purpose of track.
Compared with prior art, the invention has the beneficial effects as follows:
Tool making of the present invention is simple, and is easy to operate, do not need very large manpower just can reach obvious effect, saves for a long time for maintenance; In the situation that do not need follower bolt is all pulled down, can realize backing plate is put under the track, make track come back to the purpose of original height or replacing track.
Description of drawings
Fig. 1 is structural representation of the present invention.
Among the figure: the right jaw 6-QU80 of the left jaw 2-of 1-ringbolt 3-steel rope 4-crane hook 5-type track 7-bearing pin screw 8-track pad 9-rail pressing plate 10-nut 11-holding-down bolt
The specific embodiment
Be described in detail technology contents of the present invention below in conjunction with accompanying drawing.
A kind of rail lifting method of heavy rail track is lifted convenient for maintaining thereby the method adopts a kind of special-purpose rail lifting device and hoisting crane to cooperate with track.See Fig. 1, the rail lifting device comprises left jaw 1, right jaw 5, ringbolt 2, steel rope 3, crane hook 4, bearing pin screw 7, and left jaw 1, right jaw 5 connect by bearing pin screw 7, are provided with ringbolt 2 on left jaw 1, right jaw 5 tops; Crane hook 4 passes the suspension ring of ringbolt by steel rope 3, be connected with left jaw 1 and right jaw 5;
When work, crane hook utilizes left and right jaw to clamp QU80 type track by steel rope, it is that 12 meters QU80 type track 7 lifts with length that crane hook 4 relies on steel ropes 3 to lift by crane simultaneously a plurality of left jaws 1 and right jaw 5, then at QU80 type track 7 bottom attachment rail backing plates 8, after installing track pad 8, attachment rail pressing plate 9 is connected rail pressing plate 9 fixing with nut 10 with holding-down bolt 11.Namely realize not needing QU80 type rail pressing plate bolt is all pulled down, levelling track or replacing damage the purpose of track.
