One fixed plate 16 is welded with a spring 17 in each fixed plate 16, and spring 17 is welded on far from one end of fixed plate 16
On tooth plate 13, spring 17 is acted on so that tooth plate 13 and the holding meshing state of straight shape tooth 5, make the first sliding block 7 not by external force
When keep stable position；
It is welded with a traveller 8 on each first sliding block 7, a sliding sleeve 9 is arranged on traveller 8, is welded on sliding sleeve 9
There is the first rotation seat 10, the first rotation seat 10 is rotatably connected to rotating bar 11 using pin shaft, and rotating bar 11 is far from the first rotation seat
10 one end is rotatably connected to the second rotation seat 12 using pin shaft, and the second rotation seat 12 is welded on tooth plate 13, and position is corresponding
Two sliding sleeves 9 on be respectively welded circle set 18 and cylinder 19, circle set 18 is set on cylinder 19, the only circle set 18 relatively of cylinder 19
Output is axially moved, and when circle 18 stress of set move upwards, cylinder 19 is moved upwardly together with round set 18, and when circle set 18 is upward
When movement, tooth plate 13 is disengaged from straight shape tooth 5 when rotating bar 11 rotates.
It is welded with handle 21 on circle set 18, is pulled upwardly circle set 18 convenient for staff；Limit is welded on first sliding block 7
Block 25, the both ends of limited block 25 and fixing steel plate 20 respectively with bracket 1 offset, it is ensured that the first sliding block 7 is only capable of in first sliding groove 6
It is moved along 1 direction of bracket；
Two sides adjacent to each other of bracket 1 are respectively welded the first screw rod 22 and the second screw rod 23,22 He of the first screw rod
Second screw rod 23 is threaded with thread bush 24 jointly, and the thread rotary orientation of the first screw rod 22 and the second screw rod 23 is on the contrary, rotation spiral shell
The relative position of adjustable two brackets 1 of line set 24, so that the present apparatus is suitable for the Wharf Platform track construction of sizes；Often
At least provided with two leveling nuts 3 on a bracket 1, two brackets 1 may make to keep horizontal to guarantee to rotate leveling screw rod 4
State, so that fixing steel plate 20 keeps vertical state.
The present apparatus is placed in track groove, water intaking leveling ruler is placed on two brackets 1, the lower end of each leveling screw rod 4
It offsets with the surface of track groove, since the uneven surface of track groove rotates at this time so horizontal ruler cannot keep horizontality
The height of the adjustable leveling nut 3 being threadedly coupled with it of leveling screw rod 4, rotation leveling screw rod 4 is until horizontal ruler is shown repeatedly
Two brackets 1 are in a horizontal state；It is worth noting that: the first sliding block 7 is square slider, and fixing steel plate 20 should be with the first sliding block 7

Compressed spring 17 can be such that it moves until tooth plate 13 is disengaged with straight shape tooth 5 along 1 direction pull handle 21 of bracket, until
The distance between two fixing steel plates 20 of the same side are adjusted to design value.
To sum up, leveling screw rod 4 by turn may make two brackets 1 to keep horizontality, at this time fixing steel plate 20 and water
Plane is vertical；Pull up handle 21 make tooth plate 13 and straight shape tooth 5 be disengaged from can running fix steel plate 20 position so that
The spacing of two fixing steel plates 20 is setting value, and handle 21 is unclamped after determining in position, and tooth plate 13 generates under the action of spring 17
Movement with straight shape tooth 5 until offset, so that tooth plate 13 and 7 part-structure of the first sliding block can not continue to slide, even if fixing steel plate
20 position keeps relatively fixed；It takes bolt to be welded to tightly abut against with fixing steel plate 20 at this time, and is welded to track
On the positioning plate of rooved face, the precise positioning of track bolt and welding can be completed.
When be used for various sizes of track when, can turn thread bush 24, due to 23 screw thread of the first screw rod 22 and the second screw rod
It is oppositely oriented and be threadedly coupled simultaneously with thread bush 24, so the first screw rod 22 and the second screw rod 23 can counter motion so that two
Spacing between a bracket 1 is adjusted, and cylinder 19 is equivalent to circle set 18 and generates sliding at this time, so that the spacing of two brackets 1
Adjustment does not influence position and the movement of 20 part-structure of fixing steel plate.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
