The double-blocked rail without ballast construction technology is a kind of novel railway job practices, and it is that railway roadbed is changed into cast-in-place board-like ballast bed structure.Sleeper is designed to symmetrical two pedestals and constitutes one by the reinforcing bar cast.Earlier in the ballast bed subgrade both sides a plurality of legs (separate case is applied for a patent) are set during construction, roadbed is carried out the horizontal level measurement and positioning, fluid concrete constitutes way of concrete foundations, and sleeper is embedded on the not solidified way of concrete foundations in groups.For guaranteeing accurate location and the horizontal accuracy of sleeper on roadbed, the crossbeam (separate case is applied for a patent) that connects on the leg of location can make the two accurate location, guarantees that thus sleeper is accurately positioned in the desired location of roadbed and guarantees desired level.Adopt mode of vibration that fixed mount sleeper group is combined with way of concrete foundations by load units (separate case is applied for a patent).Fixed mount promptly is to guarantee the pinpoint critical component of sleeper.In the construction site, how to judge whether the precision of fixed mount meets the requirement of sleeper laying, just need an easy measuring appliance.
Summary of the invention
The purpose of this utility model promptly is to propose a kind of double-blocked rail without ballast to lay the job site test measuring device of using fixed mount.
For guaranteeing the laying geometric accuracy of sleeper, at first must guarantee the geometric accuracy of fixed mount, that is guarantee fixed mount location benchmark-vee-block center line that benchmark--the distance of rhombic plate centreline space is accurate with the sleeper location.The fixed mount test measuring device that the utility model proposed promptly is will be implemented in the job site transverse precision of the horizontal direction of the location benchmark of fixed mount and rhombic plate is carried out quick, easy inspection.
The utility model realizes that the technical scheme that above-mentioned purpose is taked is: a kind of double-blocked rail without ballast is laid the job site test measuring device with fixed mount, described measurement measurer comprises two groups of L type benchmark rod members, L type benchmark rod member is made up of cross bar 7 and column 12, and column 12 connects firmly the end at cross bar 7; At the two ends on cross bar 7 tops a benchmark mount pad is set respectively, on the benchmark mount pad of column far-end, be connected with datum plane piece 8, on the benchmark installation seat surface of column near-end, a half-cylindrical location benchmark 5, the axis of half-cylindrical location benchmark 5 and the axis normal of cross bar 7 are set by mount pad 6; Be provided with framework 11 corresponding to each benchmark mount pad, framework 11 connects firmly pressing plate 10 is being set on the cross bar 7 and on framework 11, and pressing plate 10 connects firmly with framework 11; Be provided with in the middle of the pressing plate in order to what be connected and fixed and compress handwheel 9 with fixed mount; , have measuring basis face 14 on the column, obtain measuring basis face 14 and half-cylindrical distance of locating between the benchmark 5 by accurate processing and adjustment; Have 5 and measure piece 13, it is interior angular structure, and its interior angle is with identical with the angle of fixed mount sole.
The column 12 of two groups of L type benchmark rod members is different with half-cylindrical distance of locating between the benchmark 5.
The half round post of two groups of L type benchmark rod members location benchmark 5 is corresponding with the V-type measuring basis piece 1 that distributes of inside and outside dihedral on the fixed mount respectively, and the datum plane piece 8 of two groups of L type benchmark rod members is corresponding with the benchmark plain block 3 that distributes of inside and outside dihedral on the fixed mount respectively.During use, two V-type measuring basis pieces 1 that are inside and outside dihedral distribution on the fixed mount lay respectively on the half round post location benchmark 5 of two groups of L type benchmark rod members, two benchmark plain blocks 3 on the fixed mount lay respectively on the datum plane piece 8 of column far-end of two groups of L type benchmark rod members, by pressing plate and locking handwheel fixed mount is fixed, fixing, nylon wire of tensioning between two columns are as measuring basis; Place measurement piece 13 in the outside of each sole, by measuring nylon wire and the spacing of measuring interblock, by the deviation of spacing dimension, promptly whether the decidable fixed mount is out of shape, and whether deflection exceeds tolerance band, whether satisfies the requirement of sleeper laying.
The utility model utilizes the benchmark vee-block of fixed mount and the reference plane that the benchmark plain block is formed, L type benchmark rod member is installed thereon, deviation between detection reference vee-block center line and rhombic plate by deviate, judges whether fixed mount satisfies the requirement of sleeper laying.
Whether the fixed mount test measuring device that the utility model proposes can be at the construction field (site) laid ballastless track sleeper and is out of shape with fixed mount, and the requirement whether whether deflection exceed tolerance band, satisfy sleeper laying is measured accurately, judged.
