Underground railway track side boundary determinator
Technical field
The utility model relates to a kind of determinator that is used on the track, exactly is a kind of underground railway track side boundary determinator.
Background technology
In the subway work process, track one side need be installed the auxiliary equipment or the platform of subway.These equipment or platform require the distance of underground railway track to equate.For example, in the sound barrier process is installed, need measure the position of the column of sound barrier, thereby the distance that guarantees sound barrier and track is consistent.In rectilinear orbit mensuration process, common dip stick can be accomplished, but in the curve track section, the common survey chi not only can not reach the requirement of mensuration accurately, and measures often, and Measuring Time is long.
The utility model content
The purpose of the utility model provides a kind of underground railway track side boundary determinator, not only can improve the precision of the mensuration of rail side boundary, can also practice thrift Measuring Time, increases work efficiency.
The utility model is realized through following technical scheme: comprise base, spirit level is installed on the base for realizing above-mentioned purpose; Two blocks are installed in the base bottom; Two blocks are stuck in the inboard of track, and base is offered the through hole that communicates up and down with the track correspondence position, in the upper end of the through hole of base fixed installation lock nut; The adjusting bolt is set on the lock nut, and the screw rod of regulating bolt is in through hole; Bracing frame is installed in the base upper end, installs support on the bracing frame, and upper bracket one end is offered the dip stick groove, the dip stick that installation can be slided in the dip stick groove.
In order further to realize the purpose of the utility model, can also adopt following technical scheme: described bracing frame is the scissor-type lifting gear, and the scissor-type lifting gear comprises to be cut yoke, cut fork shaft and cut the bolt axle; Chute is offered in the upper bracket bottom, and two hinge seats are installed in the chute, cuts yoke respectively through two hinge seats and upper bracket hinge for two of scissor-type lifting gear upper end; Base is laterally offered groove; Base one side is installed two fixed mounts, on two fixed mounts leading screw is set, and two sections opposite screw threads are set on the leading screw; Nut is installed respectively on every section screw thread, is cut yoke and distinguish hinge for two of the penetrating groove in two nuts outside and scissor-type lifting gear bottom; Leading screw one end is installed gearbox, and gearbox one side is installed rocking bar, and turbine and worm is installed in the gearbox, and the axle of worm gear is connected with rocking bar, and the axle of worm screw is connected with leading screw.
The advantage of the utility model is: measurement mechanism and track are benchmark, and measuring process is stable, have guaranteed the boundary accurate of measuring; Simultaneously, the utility model only needs one-shot measurement just can confirm the position, has practiced thrift the time of measuring, and has improved operating efficiency.The utility model also has compactness simple for structure, advantage cheap for manufacturing cost and easy to use.

Reference numeral: 1 dip stick, 2 dip stick grooves, 3 upper brackets 4 are cut yoke 5 hinge seats 6 and are cut fork shaft 7 and cut bolt axle 8 spirit levels 9 bases 10 leading screws 11 and pass through groove 12 blocks 13 through holes 14 lock nut 15 and regulate bolts 16 tracks 17 nuts 18 fixed mounts 19 chutes 20 gearboxes 21 rocking bars.
The specific embodiment
The described underground railway track side of the utility model boundary determinator, as shown in Figure 1, comprise base 9; Spirit level 8 is installed on the base 9, and the inboard that 12, two blocks 12 of two blocks are stuck in track 16 is installed in base 9 bottoms; Base 9 is offered the through hole 13 that communicates up and down with track 16 correspondence positions; In the upper end of the through hole 13 of base 9 fixed installation lock nut 14, be provided with on the lock nut 14 and regulate bolt 15, the screw rod of regulating bolt 15 is in through hole 13; Bracing frame is installed in base 9 upper ends, installs support 3 on the bracing frame, and upper bracket 3 one ends are offered dip stick groove 2, the dip stick 1 that installation can be slided in the dip stick groove 2.During use, base is placed on the track 16, two blocks 12 are stuck in the inboard of track 16, twist and regulate bolt 15, through spirit level 8 whole device are up to the standard.At this moment, extract dip stick 1 out, confirm the position measured, by the staff in the relevant position enterprising row labels and record.No matter be straightway or curved section, the position of location remains and parallel track, thereby has guaranteed sound barrier and parallel track.The utility model only needs one-shot measurement just can accurately locate, and has saved Measuring Time, thereby has improved operating efficiency.
In order to adapt to different working environments in the subway, as depicted in figs. 1 and 2, described bracing frame is the scissor-type lifting gear, and the scissor-type lifting gear comprises to be cut yoke 4, cut fork shaft 6 and cut bolt axle 7; Chute 19 is offered in upper bracket 3 bottoms, and 19 install two hinge seats 5 in the chute, cuts yoke 4 respectively through two hinge seats 5 and upper bracket 3 hinges for two of scissor-type lifting gear upper end; Base 9 is laterally offered groove 11; Base 9 one sides are installed two fixed mounts 18; On two fixed mounts 18 leading screw 10 is set; Two sections opposite screw threads are set on the leading screw 10, cut yoke 4 hinges respectively for two that 17, two penetrating grooves in nut 17 outsides of nut and scissor-type lifting gear bottom are installed respectively on every section screw thread; Leading screw 10 1 ends are installed gearbox 20, and gearbox 20 1 sides are installed rocking bar 21, and turbine and worm is installed in the gearbox 20, and the axle of worm gear is connected with rocking bar 21, and the axle of worm screw is connected with leading screw 10.When needs adjustment dip stick 1 height; Rotation rocking bar 21 drives leading screw 10 rotations through the worm and gear break-in, and two nuts 17 move inward simultaneously or expand outwardly along leading screw 10; Adjust up or down thereby make the scissor-type lifting gear drive upper bracket 3, reach best correct position.
Except in sound barrier is installed, measuring the position of column, can also apply to the construction survey of subway evacuation platform or the measurement of railway pillar foundation ditch location survey and mast gauge.
The technical scheme of the utility model is not restricted in the scope of the described embodiment of the utility model.The utility model not technology contents of detailed description is known technology.
