Summary of the invention
The purpose of this utility model provides a kind of positioning framework of plate-type ballastless track I template fastener locating rack, cooperates positioning baffle can determine the accurate position of WJ-7 type fastener system iron chair fast, thereby lays high-speed track fast.
The positioning framework of plate-type ballastless track I template fastener locating rack, it is characterized in that: comprise the connection support between a pair of locating rack guide rail and the locating rack guide rail, described locating rack guide rail is the straight shaft-like of cross section unanimity, the bottom of locating rack guide rail is the track base of bottom surface level, be vertical supporting seat on track base, be positioned at the relevant position that connects support on the supporting seat and be provided with the support fastener hole that is used for fixing the connection support.
The length of described positioning framework promptly is the length of locating rack guide rail, is 4800 millimeters, and the width of described positioning framework is the gabarit length of two locating rack guide rails, is 1680.8～1681.2 millimeters.
Supporting in each one connection at locating rack guide rail two ends is that the positioning framework single pole supports, and it is the support of posting rack double lever that the connection between a pair of positioning framework single pole supports is supported.
It is the single support bar that two ends are fixed with the support fixation plate that described positioning framework single pole supports, and described support bar is a rectangular tube.
It is two support bars that two ends are fixed with the support fixation plate that described posting rack double lever supports, and is fixed with supporting linkage between two support bars, and described support bar is a rectangular tube.
The utility model is in the locating rack installed of WJ-7 type fastener, cooperates positioning baffle to use, and can realize the accurate position of WJ-7 type fastener system iron chair determining easily and fast, for the efficient high-speed track of laying provides convenience.

Among the figure: 1-locating rack guide rail, 2-positioning framework single pole supports, and 3-posting rack double lever supports, the 4-supporting seat, the 5-track base, 6-supports fastener hole, 7-support fixation plate, 8-support bar, 9-supporting linkage.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified: the positioning framework of board fastener locating rack as shown in Fig. 1,2 comprises that the connection between a pair of locating rack guide rail 1 and the locating rack guide rail is supported.Shown in Fig. 3,4,5, described locating rack guide rail 1 is the straight shaft-like of cross section unanimity, the bottom of locating rack guide rail 1 is the track base 5 of bottom surface level, be vertical supporting seat 4 on track base 5, be positioned at the relevant position that connects support on the supporting seat 4 and be provided with the support fastener hole 6 that is used for fixing the connection support.
Locating rack guide rail 1 directly contacts positioning baffle and the required iron chair of track laying, plays the directly effect of the definite accurate position of iron chair of amplification of reference position according to positioning baffle.Therefore locating rack guide rail 1 shape and frame size accuracy own requires very high.The processing suggestion of locating rack guide rail uses cold rolling cage guide T75 (or bigger specification) machine to finish, to guarantee dimensional accuracy.Because the locating rack rail length is bigger, notes the influence of axial deflection to machining accuracy during machine.After two locating rack guide rails are fixed simultaneously boring, porose location dimension tolerance be ± 0.15 millimeter.
As Fig. 1,2, the length of described positioning framework promptly is the length of locating rack guide rail 1, is 4800 millimeters, and the width of described positioning framework is the gabarit length of two locating rack guide rails 1, is 1680.8～1681.2 millimeters.
As can be seen from Fig. 2, supporting in each one connection at locating rack guide rail 1 two ends is that the positioning framework single pole supports 2, and it is posting rack double lever support 3 that the connection between a pair of positioning framework single pole support 2 is supported.
Shown in Fig. 8,9, it is single support bars 8 that two ends are fixed with support fixation plate 7 that described positioning framework single pole supports 2, and described support bar 8 is rectangular tubes.
As Fig. 6,7, it is that two ends are fixed with between 8, two support bars 8 of two support bars of support fixation plate 7 and are fixed with supporting linkage 9 that described posting rack double lever supports 3, and described support bar 8 is rectangular tubes.
Supporting linkage 9 can use solid steel block to fixedly connected with support bar 8.
Connect supporting and can adopting 40 * 60 millimeters, thickness is that 3 millimeters rectangular tube and steel plate welding made, and after welding is finished and stress fully discharges, carries out machine again.When both ends of the surface are carried out machine, note bulk deformation.
Whole positioning framework requires rigidity preferably.Positioning framework requires accurately to install, and guarantees that the positioning framework width dimensions is accurate, and is firm.After the locating rack installation, use vernier caliper measurement, behind assurance 1681 ± 0.1 mm sizes, add corresponding pad then and adjust to 1682.3mm, use vernier caliper measurement to confirm.Wherein, 1682.3mm is of a size of reference point, can adjust according to actual measurement gauge value plus-minus pad at the scene during debugging, and then reach the gauge that needs.
Use mounting means about locating rack and positioning framework sees the relevant patent document of CRTS I template fastener locating rack series that our company declares synchronously for details.
