Description

Rail fastener vertical rigidity comprehensive measurement device
Technical field
The utility model relates to field of engineering technology, particularly rail fastener vertical rigidity comprehensive measurement device.
Background technology
Rail fastening vertical rigidity stops rail relative to the tolerance of the capacity of water of sleeper generation vertical displacement, is the important indicator evaluating rail fastening performance quality.Along with high-speed railway constantly raises speed, the technical property requirements of rail fastening rigidity is also improved constantly.The vertical rigidity of Measurement accuracy rail fastening determines rail fastening rigidity, research track geometry, carries out and normal support the needs repairing, guarantee traffic safety.But, domesticly at present also do not have a kind ofly can to facilitate, the device of Measurement accuracy rail fastening vertical rigidity.
Utility model content
The purpose of this utility model be to provide a kind of provide structure simple, be easy to carry, the rail fastening vertical rigidity surveying instrument that easy to operate, measurement result accuracy is high.
The purpose of this utility model is achieved through the following channels: rail fastener vertical rigidity comprehensive measurement device, and main supporting plate four angles are movably installed with a threaded rod respectively, is fixed with a secondary back up pad respectively bottom two threaded rods of the left and right sides; Be movably installed with a pair screw thread claw beam side by side at Main shoe plate middle position, the shaft top of screw thread claw beam is helicitic texture, and bottom is the clamp of L shape, the shaft of two screw thread claw beams is movably installed with a top board; The shaft of described threaded rod above main supporting plate is equipped with two nuts, the shaft below main supporting plate is equipped with a nut, the shaft of described screw thread claw beam above top board is equipped with a nut.
As the further optimization of this programme, between the clamp of two described screw thread claw beams, be connected with adjusting bolt.
The utility model rail fastener vertical rigidity comprehensive measurement device, it is by the vertical rigidity of the creationary Combination application of conventional tool such as force cell, hydraulic jack and clock gauge in measurement rail fastening, have structure simple, be easy to carry, easy to operate, measurement result accuracy advantages of higher, there is foreseeable huge economic value and social value.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the main TV structure schematic diagram of the utility model;
Fig. 2 is the utility model side-looking structural representation;
In figure, main supporting plate 1, the secondary back up pad 3 of threaded rod 2, top board 4, rail 5, nut 6, screw thread claw beam 7, adjusting bolt 8.
Embodiment
As shown in Figure 1 and Figure 2, the utility model rail fastener vertical rigidity comprehensive measurement device, it is movably installed with a threaded rod 2 respectively on main supporting plate 1 four angles, is fixed with a secondary back up pad 3 bottom two threaded rods 2 of the left and right sides respectively; Be movably installed with a pair screw thread claw beam 7 side by side at the middle position of main supporting plate 1, the shaft top of screw thread claw beam 7 is helicitic texture, and bottom is the clamp of L shape, the shaft of two screw thread claw beams 7 is movably installed with a top board 4; The shaft of described threaded rod 2 above main supporting plate 1 is equipped with two nuts 6, the shaft below main supporting plate 1 is equipped with a nut 6, the shaft that described screw thread claw beam 7 is square is on the top plate 4 equipped with a nut 6.Adjusting bolt 8 is connected with between the clamp of two described screw thread claw beams 7.
During use, hydraulic jack is installed between main supporting plate and top board, between hydraulic jack and top board, force cell is installed, force cell is the force cell with readout instrument, readout instrument and force cell support the use, when hydraulic jack work applies vertical force to push rod, on the readout instrument of force cell, directly can read the size of this vertical force, its convenient reading, precision are high.The driving force size of ultra-thin hydraulic jack can be controlled by operation hydraulic hand pump and in conjunction with the readout instrument of force cell, and then the size controlled the vertical force that rail applies, measurement mechanism can apply the vertical force of different size to rail, and measure rail when bearing the vertical force of different size, the size of its vertical displacement.
The vertical force size that rail bears equals the vertical force size that type hydraulic jack applies the iron plate of two screw sockets, by the induction of force cell, can directly obtain from the readout instrument display of force cell, the size of rail vertical displacement then obtains by clock gauge measurement, and shows screen display at the reading of clock gauge.Suffered by rail, transverse horizontal power will be evenly distributed on four groups of tested rail fastenings, like this, can suffered by the size determination rail fastening of vertical force suffered by rail the size of vertical acting force, again in conjunction with displacement measured by rail place clock gauge directly over each rail fastening, the lateral stiffness of rail fastening can be calculated.
The above; be only embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the utility model; the change can expected without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
