Description

A kind of overhead contact built-in conduit gap measuring device
Technical field
The utility model relates to building construction measurement equipment, particularly overhead contact built-in conduit gap measuring device.
Background technology
At present, electrified railway tunnels, subway engineering pre-buried channel flow in advance in civil engineering process, then contact net davit is arranged on two conduits, then carry out contact net laying construction.The width on contact net davit chassis, be fixing with the position of conduit tie point, the spacing of two therefore pre-buried conduits must reach standard.Need to measure the spacing of two conduits before installing contact net davit.The pre-buried nearly 10 meters of height in conduit distance ground, the mode that ladder personnel measure to top ruler is set up in on-the-spot employing at present, and both dangerous, efficiency is low again.Can reach similar measurement object instrument at present few, expensive, complex structure, environmental requirement standard is high, and matters scene does not need.
Utility model content
The purpose of this utility model is to provide a kind of overhead contact built-in conduit gap measuring device, makes it have noncontacting measurement, and structure is simple, advantage easy to use.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of overhead contact built-in conduit gap measuring device, for tunnel underground engineering in civil engineering process in advance the spacing of pre-buried channel flow carry out Measurement accuracy.Form primarily of Measurement scales chi 1, two cross line lasers (2 and 3), the laser holder (4 and 5) of two verniers with a scale, transverse horizontal ball 6, vertical equity ball 7, pallet 8, three-legged support 9; Wherein, Measurement scales chi 1 is connected on three-legged support 9 by pallet 8, and cross line laser to be vertically fixed on Measurement scales chi 1 by the laser holder (4 and 5) of vernier with a scale and can along the longitudinal sliding motion of Measurement scales chi by two cross line lasers (2 and 3); The front of Measurement scales chi arranges transverse horizontal ball 6, and its side arranges vertical equity ball 7.
Like this, cross line laser 2 is vertically fixed on Measurement scales chi and also can horizontally slips along Measurement scales chi by the laser holder 4 of vernier with a scale; Cross line laser 3 is vertically fixed on Measurement scales chi and also can horizontally slips along Measurement scales chi by the laser holder 5 of vernier with a scale; One, the cross laser line that after fixing, cross line laser 2 sends is parallel with Measurement scales chi, and another cross laser line is vertical with Measurement scales chi; One, the cross laser line that after fixing, cross line laser 3 sends is parallel with Measurement scales chi, and another cross laser line is vertical with Measurement scales chi; Cross line laser 2, cross line laser 3 are transmitted into that two wherein parallel with Measurement scales chi 1 laser rays of the cross laser line of tunnel top overlap, two other laser rays is parallel, the laser rays overlapped is vertical with two parallel laser lines, article two, between parallel laser line, vertical laser linear distance is determined by Measurement scales chi, realizes measurement two pre-buried channel flow spacings.
Compared with prior art, the utility model accurately can complete measurement to top, low cost of manufacture without the need to setting up ladder personnel, and security is good, and work efficiency is high.Especially suitable tunnel underground engineering construction onsite application.

Embodiment
As illustrated in fig. 1 and 2, the utility model overhead contact built-in conduit gap measuring device forms primarily of the laser holder (4 and 5) of Measurement scales chi 1, cross line laser 2, cross line laser 3, vernier with a scale, transverse horizontal ball 6, vertical equity ball 7, pallet 8, three-legged support 9.Wherein cross line laser 2 is vertically fixed on Measurement scales chi 1 and also can horizontally slips along Measurement scales chi 1 by the laser holder 4 of vernier with a scale; Cross line laser 3 is vertically fixed on Measurement scales chi 1 and also can horizontally slips along Measurement scales chi by the laser holder 5 of vernier with a scale; One, the cross laser line that after fixing, cross line laser 2 sends is parallel with Measurement scales chi, and another cross laser line is vertical with Measurement scales chi; One, the cross laser line that after fixing, cross line laser 3 sends is parallel with Measurement scales chi, and another cross laser line is vertical with Measurement scales chi; Cross line laser 2, cross line laser 3 are transmitted into that two wherein parallel with Measurement scales chi laser rays of the cross laser line of tunnel top overlap, two other laser rays is parallel, the laser rays overlapped is vertical with two parallel laser lines, article two, between parallel laser line, vertical laser linear distance is determined by the scale strip 102 of Measurement scales chi, realizes measurement two pre-buried channel flows (201 and 202) spacing.
Measurement scales chi 1 is Al-alloy products, mark 1000mm scale.Centre position, bottom embedding nut is connected with the bolt on pallet 8.Cross line laser is laser instrument manufacturer approved product, cheap, meets on-the-spot needs.The laser holder (4 and 5) of vernier with a scale is metallic article, according to cross line laser, the processing of Measurement scales ruler lattice, guarantees stable fixed cross laser line generator.Can be seen by Fig. 2, Measurement scales chi 1 has the laser holder of the being convenient to vernier with a scale groove 101 along its straight skidding.Pallet 8 center adopts conventional stud to be connected with the nut on Measurement scales chi 1.Three-legged support 9 is Al-alloy products, plays support and adjust Measurement scales chi 1 to act on.Transverse horizontal ball 6, vertical equity ball 7 select suitable column type horizontal ball to be fixed on Measurement scales chi according to Measurement scales ruler lattice, laterally, longitudinally respectively install one.
During use, first three-legged support 9 to be placed in the tunnel that needs to measure spacing immediately below two pre-buried channel flows on ground, Measurement scales chi is arranged on pallet 8, adjustment three-legged support 9 is by transverse horizontal ball determination Measurement scales chi horizontal level, open cross line laser 2, cross line laser 3 switch, horizontally rotate adjustment Measurement scales chi 1, along Measurement scales chi longitudinally left and right adjustment cross line laser 2 and cross line laser 3 position, two parallel laser lines that cross line laser (2 and 3) is projected on tunnel top pre-buried channel flow overlap with tested conduit (201 and 202), according to vernier pointer (the 401 and 501) data on Measurement scales bar 102 of the laser holder of vernier with a scale, calculate the distance values of two pointers, namely the distance of tunnel top two pre-buried channel flows is measured, can determine that whether tunnel top two pre-buried channel flows are parallel simultaneously.
