Abstract
Provided is a midpoint measuring device used for fast measuring a rail surface in a railway. The midpoint measuring device comprises a mark rod separation sheet, a mark rod pin roll, a steel rail positioning plate, a rubber blanket, fastening buckles, a centering rod installing seat, a fastening bolt, and a positioning support and is characterized in that the centering rod installing seat is disposed on the positioning support, that the mark rod separation sheet is disposed on the outer side of the centering rod installing seat, that the steel rail positioning plate and the rubber blanket are disposed on the lower end of the centering rod installing seat, and that the fastening buckles are disposed on the sides of the steel rail positioning plate. Because of no need in measuring and marking the rail surface, the midpoint measuring device is capable of directly fixing the position of a midpoint of the rail surface so as to decrease operating time by 40 percent. In addition, because of no need in marking the rail surface, unclear marks on the rail surface caused by avoiding trains are prevented and thus measuring precision is substantially increased.
Description
Technical field:
The utility model relates to field of measuring technique, device during particularly a kind of railroad survey rail level divides fast.
Background technology:
Current in existing railway survey, when existing line is carried out plane surveying, adopt method of deflection angle, before carrying out measurement of angle at every turn, in need dividing rail level, mode is to adopt steel ruler to measure in the branch, thereby measure the branch mid point, after measuring, employing talcum pen etc. carries out mark to minute mid point, consuming time longer, once there is train to pass through, survey crew is dodged in the road down, and mark can thicken unclear owing to rolling of wheel in dividing, can't continue to measure, at this moment survey crew needs to divide mid point to repair mark to each again, when the high ferro circuit homework, because speed of a motor vehicle height, train interval is short, so task difficulty is also very big, run into often to carry out repairing for 2-3 time and just finish one section 300 meters measurement, greatly influenced measurement efficient and precision, when carrying out curved measurement, per 20 meters circuit once divided in and mark, it is various to work in the branch, is carrying out must carrying out the measurement of angle of 2 survey time when the curve big angle is measured, time spent is longer, and the centering frame is aluminum alloy material, and it is little to conduct oneself with dignity, and very easily toppled over by windage, cause instrument damage easily, and the danger that makes the both sides rail connect electricity is arranged.
Summary of the invention:
The purpose of this utility model provide a kind of measure the high railroad survey rail level of efficient and precision divide fast in device.
The utility model is to realize like this, it comprises mark post catch, mark post bearing pin, rail location-plate, rubber blanket, fastening buckle, centering rod mount pad and fastening bolt, locating support, it is characterized in that the centering rod mount pad is arranged on the locating support, arranged outside at the king-rod mount pad has the mark post catch, be provided with rail location-plate and rubber blanket in the lower end of king-rod mount pad, be provided with fastening buckle in the side of rail location-plate.
The utility model is owing to need not rail level is measured and mark, can directly fixedly go out rail level and divide point midway, shortened for 40% activity duration, simultaneously owing to need not to carry out mark at rail level, thereby the rail level mark that has prevented from dodging train and caused is smudgy, has improved measuring accuracy greatly.
Description of drawings:
Fig. 1 is the structural representation of device during the railroad survey rail level divides fast
Fig. 2 is the left view of Fig. 1
Fig. 3 is the vertical view of Fig. 1
Embodiment:
Shown in Fig. 1-3, device comprised mark post catch 1 during this railroad survey rail level divided fast, mark post bearing pin 2, rail location-plate 3, rubber blanket 4, fastening buckle 5, centering rod mount pad 6, fastening bolt 7 and locating support 8, centering rod mount pad 6 is arranged on the locating support 8, arranged outside at king-rod mount pad 6 has mark post catch 1, be provided with rail location-plate 3 and rubber blanket 4 in the lower end of centering rod mount pad 6, be provided with fastening buckle 5 in the side of rail location-plate 3, during use, at first see the rail model clearly, select corresponding rail location-plate 3, centering rod is mounted in the centering rod mount pad 6 then, tighten the fastening bolt 7 of centering rod mount pad, make it form one, below only need hand-held centering rod to operate.Confirm that fastening buckle 5 is in open mode, device was placed on the rail and both can measures during hand-held centering rod divided the existing railway survey rail level fast, because Measuring Time is in 3-5 second when using method of deflection angle to carry out little angular measurement in curve, so fastening buckle 5 is in open mode always, hand steered centering rod can be finished measurement; Only when carrying out big angular measurement because consuming time longer, hand steered shakiness is so adopt fastening buckle 5 secure fit centering framves to finish measurement.
