Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.

In the description of the present invention, it should be understood that term " on ", "lower", "front", "rear", "left", "right", The orientation or positional relationship of the instructions such as "top", "bottom", "inner", "outside" is to be based on the orientation or positional relationship shown in the drawings, and is only This is practical for ease of description and simplifies description, rather than the device or element of indication or suggestion meaning must have specific side Position is constructed and operated in a specific orientation, therefore should not be understood as the limitation practical to this.

Referring to Fig.1-4, a kind of track bolt welding support, including two brackets 1, two brackets 1 are arranged in parallel, two branch The side of frame 1 away from each other is welded with two link blocks 2, and a leveling nut 3 is welded on each link block 2, leveling Nut 3 should keep plumbness with bracket 1, and each leveling nut 3 be threaded with a leveling screw rod 4, on two brackets 1 Several fixing steel plates 20 are symmetrically arranged with, corresponding two fixing steel plates 20 in position are connected with position adjusting mechanism jointly, Width adjusting mechanism is provided between two brackets 1, rotation leveling screw rod 4 can adjust the height of leveling nut 3, so that two A bracket 1 keeps horizontality.

Position adjusting mechanism includes the first sliding block 7, and each bracket 1 one end adjacent to each other is provided with a column straight shape tooth 5, First sliding groove 6 is offered on each bracket 1, the first sliding block 7 slides in first sliding groove 6, opens up on each first sliding block 7 There is a second sliding slot 14, slidably connect second sliding block 15 in each second sliding slot 14, on each second sliding block 15 It is welded with a tooth plate 13, tooth plate 13 can be engaged with the straight shape tooth 5 on bracket 1 just, is welded on each first sliding block 7 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 Vertical welding is fixed, and guarantees that the first sliding block 7 keeps plumbness with bracket 1.

Handle 21 is pulled up, drives circle set 18 and cylinder 19 to move upwards, the sliding sleeve 9 of two sides is driven to move upwards, the One rotation seat 10 is moved upwards with sliding sleeve 9, drives rotating bar 11 to rotate, the second sliding block 15 slides simultaneously in second sliding slot 14 at this time 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.
