Abstract
The utility model relates to a track lifting device for a heavy steel rail track. The track lifting device comprises a left jaw, a right jaw, lifting bolts, a steel wire rope, a crane hook and a pin roll bolt, wherein the left jaw and the right jaw are connected by the pin roll bolt, and the lifting bolts are arranged at the upper parts of the left and right jaws; and the crane hook penetrates through a lifting ring of the lifting bolt by virtue of the steel wire rope and then is connected with the left jaw and the right jaw. The track lifting device for the heavy steel rail track provided by the utility model has the beneficial effects of being simple to manufacture and easy to operate, being capable of achieving an obvious effect without much manpower and saving a long time for maintenance, and being capable of fulfilling the purpose of placing a base plate below the track to return the track to an original height or replace the track without dismounting all follower bolts.
Description
Technical field
The utility model relates to a kind of rail lifting device of gantry crane QU80 type track.
Background technology
In the long-term process of using of gantry crane, due to 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 first all pull down QU80 type rail pressing plate bolt, just can proceed the levelling track or change the operation that damages track.
The utility model content
The purpose of this utility model is to provide a kind of rail lifting device of heavy rail track, in the situation that do not need follower bolt is all pulled down, can realize backing plate is put under track, makes track come back to the purpose of original height or replacing track.
In order to address the above problem, the utility model by the following technical solutions:
A kind of rail lifting device of heavy rail track comprises left jaw, right jaw, ringbolt, steel rope, crane hook, bearing pin screw, and left jaw, right jaw connect by the bearing pin screw, is 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.
Compared with prior art, the beneficial effects of the utility model are:
The utility model tool making 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 track, make track come back to the purpose of original height or replacing track.
Description of drawings
Fig. 1 is the utility model structural representation.
In 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 utility model 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 coordinate 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 connects by bearing pin screw 7, is 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 the QU80 type track 7 of 12 meters 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.
