Problems solved by technology

[0002] In order to facilitate the regular inspection of the tunnel, people will measure the length of the tunnel. At present, when people measure the length of the tunnel, they usually measure the length of the tunnel with a photogrammetry instrument. The photogrammetry instrument is heavy. When the tunnel is long, people’s labor intensity is high, and holding the photogrammetry instrument for a long time will easily cause people’s arm pain. In order to prevent arm pain, people will put the photogrammetry instrument on a small cart, and the small Carts are difficult to keep level, which can interfere with tunnel length measurements

Abstract

The invention relates to a movable support used for a photogrammeter, in particular to the movable support used for a tunnel length photogrammeter. The invention aims at providing the movable supportcapable of lowering the labor intensity and preventing arm aching pain and used for the tunnel length photogrammeter. According to the technical scheme, the movable support used for the tunnel lengthphotogrammeter comprises supports, a supporting plate, a bearing, a rotating shaft and the like; and the left side and the right side of the lower portion of the supporting plate are connected with the supports in a rotating manner correspondingly. According to the movable support, by means of clockwise rotation of second gears, rolling wheels can be in the horizontal state all the time, and in this way, a user can conveniently measure the tunnel length and does not need to hold the photogrammeter; then the labor intensity of the user can be lowered, and arm aching pain of the user can be prevented; and first screws on the left side and the right side can be clamped into corresponding second clamping grooves inwards, slide sleeves can be fixed in this way, and therefore the user can conveniently regulate the height of the photogrammeter.
