At the above-mentioned defective that exists in the prior art, the utility model provides a kind of direction adjustment instrument used while installing ballastless track slabs, utilizes it to regulate the track plate easily and quickly, can accelerate speed of application greatly.
The utility model is achieved by the following technical solution: a kind of direction adjustment instrument used while installing ballastless track slabs, it comprises collet, is located at the vertical direction adjusting device on collet top, the bottom surface of described collet is dull and stereotyped, edges of boards are fixed with a riser therein, have the through hole along its thickness direction on the riser; Described vertical direction adjusting device comprises base, regulates bolt, Movable bracket, base has a base plate that cooperates with above-mentioned collet, the base plate side has screw, the top of the base plate seat pipe that has an internal thread that is connected, one regulates the bolt spinning on this pipe, the lower end of this adjusting bolt has the adaptive external screw thread of internal thread with described seat pipe, its middle part has a cushion cap that is used for load-bearing, top is round bar, its top has the foreign side that uses for spanner, one Movable bracket is sleeved on the described round bar rotationally, and the outside of Movable bracket is provided with a support arm; One regulates that bolt passes through hole on the riser and the screw on the described base plate screws.
The utility model is to cooperate with the hanger of lifting usefulness on the ballastless track plate in use, generally needs several adjusting apparatus to be used.In the hanger of arm supports on the Movable bracket on the track plate,, make and regulate the bolt lifting, drive the lifting of track plate, reach purpose at vertical direction buffer rail guidance tape by Movable bracket by the adjusting bolt that the seat pipe on rotation and the base screws; By rotating the adjusting bolt that screws with base plate, base is moved in the horizontal direction along the last plane of collet, thereby reach the purpose of buffer rail guidance tape in the horizontal direction.
Direction is not offset when base is moved in the horizontal direction, and the utility model is provided with the rib of restriction base moving direction in the both sides of collet.
In order to prevent that Movable bracket from coming off in moving process, the utility model with base on the top of the corresponding Movable bracket in top of the adjusting bolt that screws of seat pipe be provided with a block, be used to prevent that Movable bracket from coming off.
The beneficial effects of the utility model are: the utility model by simply, structure design cleverly, not only realized carrying out the adjusting of both direction on the same set of device, and, can easily track plate support have been got up by Movable bracket is set.The utility model can be realized the adjusting of level and vertical direction by rotating corresponding adjusting bolt, and is easy to adjust, flexible, and adopts threaded adjusting, can reach higher degree of regulation, guarantees the installation accuracy of track plate.

The specific embodiment
Also in conjunction with the accompanying drawings the utility model is further described below by the specific embodiment:
As shown in drawings, a kind of direction adjustment instrument used while installing ballastless track slabs, it comprises collet 5, is located at the vertical direction adjusting device on collet 5 tops.The bottom surface of collet 5 is dull and stereotyped, its surface grinding, and edges of boards are fixed with a riser 7 therein, have the through hole along its thickness direction on the riser 7.Described vertical direction adjusting device comprises base 4, regulates bolt 1, Movable bracket 2, base 4 has a base plate 10 that cooperates with collet 5, the bottom surface polishing of base plate 10, its side has screw 9, the top seat pipe 8 that has an internal thread that is connected, seat pipe 8 can be made with base plate 10 one, or is welded on the base plate 10.The lower end of regulating bolt 1 has and an adaptive external screw thread of internal thread of pipe 8, and its middle part has cushion cap 6, and top is round bar, the top has the foreign side that uses for spanner, regulate on the present pipe 8 of bolt 1 spinning, because the bolt at this place is load-carrying members, so the size of screw thread should satisfy the load-bearing requirement.Movable bracket 2 is sleeved on the round bar place of above-mentioned adjusting bolt 1 and by cushion cap 6 supports, its internal diameter is slightly larger than the diameter of round bar, can relatively rotate, and the outside of Movable bracket 2 is provided with a support arm 13, the hanger that is used for the support heavy objects, Movable bracket 2 integral body should satisfy the load-bearing requirement; The screw portion of regulating bolt 3 passes through hole on the riser 7 and the screw 9 on the base plate 10 screws.
