The present invention relates to a positioning and fixing device for a light receiving detector.

順次回つて測定することができる利点がある。``Prior Art'' Conventionally, a two-dimensional level is a system in which a laser beam or the like is rotated and irradiated around the horizontal plane in a horizontal plane, and the horizontal light flux that is rotated and irradiated from this two-dimensional level is invisible, but it cannot be seen by the light-receiving element. It is possible to roughly detect light with an accuracy of about ±2 cm using the equipped light detector, and subsequently detect light with an accuracy of about ±1 mm. Therefore,
The way to use it is to install this two-dimensional level at the standard height in the center of a construction site, etc., and then follow the leveling rod while keeping it upright on the foundations of multiple buildings around it. and move the light receiving detector.
This is used when, after confirming the light receiving position, the light receiving detector is fixed to a leveling rod and the height of a foundation etc. is set to the same or predetermined height. At this time, there is an advantage that once the two-dimensional level is installed, one worker can successively walk around it and take measurements.

A light receiving detector that roughly detects the horizontal light beam irradiated from a two-dimensional level as well as precisely detects the light receiving.
A device is known in which the light receiving detector is slidably attached directly to a leveling staff, detects a light receiving position by sliding the light receiving detector with a thumbscrew, and detects the scale of the leveling staff at that position.

とではない。``Problems that the invention cannot solve'' However, the light detector is quite heavy because it contains a power supply battery, etc., so the light detector is attached directly to the leveling rod so that it can slide freely. In order to detect the light-receiving position while sliding with a thumbscrew, a special, highly accurate and stable guiding mechanism is required between the leveling rod and the light-receiving detector over the entire length of the leveling rod, which is not normally used at work sites. There was a problem in that it did not have a guide surface to guide it, or it could not be used by detachably attaching it to any leveling rod that had unevenness or scratches on its surface. In addition, the light receiving position detected by the light receiving detector covers a wide range of the leveling staff, and it is necessary to find extremely small values near the light receiving position. There is a problem in that it is not easy to combine the guide structure for detecting the light receiving position with a structure for finely adjusting the position near the light receiving position. Furthermore, in this case, depending on the situation at the surveying site, there may be obstacles in the light receiving detector guide around the leveling rod that is erected to receive the horizontal beam, or the light receiving position of the light receiving detector may be in a position that is difficult to reach. It is easy for one worker to maintain the leveling rod in an upright position, move the light-receiving detector, detect the approximate light-receiving position, then accurately fix it at the light-receiving position, and then read the leveling rod. That's not the point.

きる。"Function" According to the device of the present invention having the above configuration, a two-dimensional level is installed on a base so as to be irradiated with a rotating horizontal light beam at a reference height, and a leveling rod is placed at a surveying position that receives the horizontal light beam around the two-dimensional level. Keep it in an upright position, move the light receiving detector along the leveling staff with the light receiving element facing the rotational irradiation direction of the two-dimensional level, and attach and detach the fixed member with the side opening to the staff at the position approximately detected by the light receiving element. By freely fixing from the side direction using a vise-type fixing means, the light receiving detector can be fixed to the leveling rod in an approximate detection state via the fixing member. After that, if the light receiving detector is slightly moved along the longitudinal direction of the level rod with respect to the fixing member by the fine movement fixing mechanism and the fine movement is stopped at the precise detection position, the light receiving detector is fixed as it is by the fine movement fixing mechanism. Therefore, the worker can easily know the position of the horizontal light beam from the scale of the leveling rod.
When fixing the fixing member to the leveling staff at the roughly detected position above, and when reading the scale of the leveling staff after fixing the light receiving detector with the fine movement fixing mechanism, the operator should set the staff so that it is easy to operate and see. You can freely move it away from the standing position or tilt it.

するところ多大である。"Effects of the Invention" As described above, according to the two-dimensional level light receiving detector positioning and fixing device according to the present invention, it can be fixed at any position on the leveling rod by a vise-type fixing means in a manner that it can be attached and detached from the side. a fixed member with an open side surface; a light receiving detector that detects horizontal light flux from a two-dimensional level by rough detection and precise detection using a light receiving element; Because it has a structure consisting of a fine movement fixing mechanism that positions and fixes it in a fine movement,
The light-receiving detector is moved along the leveling staff with the light-receiving element facing the rotational irradiation direction on a two-dimensional level, and at the position approximately detected by the light-receiving element, the fixing member is precisely lengthened along the longitudinal direction of the leveling staff using the fixing means. Even if the leveling rod has no guide surface and is somewhat uneven, the light receiving detector can be roughly detected through the fixing member by freely fixing it at any position from the side of the leveling rod without sliding the distance. It has the effect of being able to be quickly and easily fixed to any leveling rod in any state,
After that, the fixing position of the fixed member was somewhat inaccurate with respect to the raised leveling staff, and the guiding surface of the leveling staff was damaged or otherwise inaccurate in order to move the fixed member along the leveling staff. However, the light receiving detector can be precisely moved slightly along the longitudinal direction of the leveling rod with respect to the fixing member by the fine movement fixing mechanism,
If the fine movement operation is stopped at the precision detection position, the light receiving detector will be positioned and fixed as it is by the fine movement fixing mechanism, and the operator can freely move and tilt the staff to a position where it is easy to see the staff without having to do any troublesome fixing work. This has the advantage of being able to accurately, quickly and easily determine the position of the horizontal light beam, and is of great practical benefit.
