Abstract

The utility model relates to a reflective measuring target specially used for a high-speed railway. The reflective measuring target comprises a body (1) and a connecting bayonet (2) that is arranged on the inner ring of the body (1) and is matched with a framework of a prism (5). The reflective measuring target is characterized in that the surface of the body (1) is printed with a reflective pure-color background and a reflective aiming pattern (3) in the other color by reflective materials. The reflective measuring target can not only be suitable for measuring in the good observation condition in daylight, but also be suitable for measuring at night and in other environments with insufficient lighting, thereby lowering the labor cost for measuring the high-speed railway and improving the measuring accuracy and the measuring efficiency.

Description

Board is observed in the special-purpose reflecting type measurement of high-speed railway

Technical field

The utility model relates to the special-purpose reflecting type measurement of a kind of high-speed railway and observes board.

Background technology

Track reference net in the high-speed railway (CPIII net), by the some positioning reference points along the equidistant laying of track circuit is that track reference point position (CPIII point position) constitutes, these track reference point positions are demarcated by the three-dimensional measurement sign that is fixedly installed in metope or the stake usually, are the benchmark of ballastless track laying and operation maintenance.When laying, need the measurement CPIII point position and the mutual alignment of the measurement point of track to concern, adhere to specification with the locus that guarantees track laying, and guarantee that it is smooth-going.When operation maintenance, also want the periodic measurement CPIII point position and the mutual alignment of orbit measurement point to concern, in time adjust when finding orbit displacement, guarantee that the position deviation of high-speed track meets the requirements, train high-speed cruising safety is smooth-going.

Measurement point on the CPIII point position is the foveal reflex point of the prism of installation on it, when measuring, need total powerstation telescope ocular crosshair intersection point to be aimed at the prism central point (reflection spot) on the CPIII point position, can finish the measurement of mutual alignment relation between CPIII point position and the survey station point behind the aligning automatically by total powerstation by human eye.Because it only is the roundlet spot that prism is seen from afar, even pass through telescope, naked eyes also are difficult to cut accurate its center, therefore, for convenience survey crew is cut the little prism central point on the accurate CPIII point position, needs on the picture frame of prism installation observe board, observes to be printed on three on the board and to sight pattern, about the horizontal center line of the line of two aiming points of sighting pattern and prism overlapping, the aiming point that pattern is sighted in the top is centered close on the vertical center line of prism.During measurement, the horizontal hair of total powerstation telescope ocular crosshair with about to sight the aiming point of pattern overlapping, it is overlapping that the aiming point of pattern is sighted in vertical hair and top, just can guarantee the central point of measurement total powerstation directed prism.

High-speed railway CPIII point position is often measured and need be in night and tunnel etc. to be carried out under the relatively poor situation of lighting condition.During measurement, it is need be in each CPIII point position other that hand-held high light torch illuminates prism on the CPIII point by a people, owing to need to measure simultaneously at a distance of hundreds of rice a plurality of positions far away, each observation needs the hand-held high light torch of many people to throw light on, 12 points of one-shot measurement position, with regard to 12 person-times of needs special-purpose prism is closely thrown light on, the labor intensive resource, efficient is low.Simultaneously, because the requirement of CPIII net form, the each point orientation is close, comparatively approaching in the total powerstation visual field, the special-purpose prism of each some position and to observe board just the same when measuring night, the CPIII point that the observation personnel are not easily distinguishable different is easy to cause sighting and measuring mistake.

The utility model content

The purpose of this utility model is exactly in order to overcome the deficiencies in the prior art, provide the special-purpose reflecting type measurement of a kind of high-speed railway to observe board, it not only is fit to the measurement of good observation condition on daytime, and can adapt to the measurement of the not enough environment of illumination such as night, the cost of labor that high-speed railway is measured be can reduce, measurement accuracy and efficient improved.

The technical scheme that its goal of the invention that realizes the utility model adopts is: board is observed in the special-purpose reflecting type measurement of a kind of high-speed railway, comprise on body, the body inner ring with the prism framework matches being connected bayonet socket (2), it is characterized in that: described body surface is printed with the reflective pattern of sighting of reflective solid background and another kind of color with reflectorized material.

Compared with prior art, the beneficial effects of the utility model are:

Be added in the reflective board of observing on the special-purpose prism of high-speed railway CPIII, enlarged the area of reflective mirror target, strengthened the contrast of target and sky or environmental background, it is easier that total powerstation is sighted, and measuring accuracy is higher; Especially when the environment of night and other lighting condition difference uses, print by reflectorized material and form owing to observe lip-deep pattern and the background colour sighted of board, background and sight pattern good reflective function is all arranged; Can be sighted by the hand-held high light torch of the personnel at survey station place and observe board, the observation personnel just can clearly observe the pattern of sighting of observing board from the total powerstation telescope, realize accurately sighting of CPIII point position.When measuring next some position, the personnel at survey station place only need the high light electric torch is aimed at the board of observing of next measurement point position, and the observation personnel just can cut standard target.Thereby make whole measuring process only need people illumination get final product, needed human resources when greatly reducing measurement have reduced the measurement cost, measure more conveniently, and efficient is higher.

The upper left corner of above-mentioned body surface or the upper right corner also are printed with the reflective board of observing and number.

Like this, when measuring, can clearly observe the numbering that each observes board self, make survey crew grasp and write down the numbering of current measurement point position easily by the total powerstation telescope.Overcome each CPIII prism when just the same, survey crew is difficult for the defective of distinctive points position, has fundamentally avoided the measurement point position to obscure and the measurement mistake brought.

Above-mentioned solid background and the reflective color of sighting pattern are any two kinds of colors in black, white, yellow, green, red, the basket.

Like this, observe the background colour of board and sight the colour contrast of pattern big, be easy to difference, the observation that is convenient for measuring personnel with sight.

The utility model is described in further detail below in conjunction with accompanying drawing and concrete embodiment.
