Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a laser measurement equipment support device that supports laser measurement equipment used in civil engineering, construction, etc.

[Prior art]

The use of laser beams for surveying is well known. For example, in order to measure whether a tunnel excavation hole is being excavated accurately, a laser beam emitting device is placed at a predetermined position on one cross section of the tunnel, and a target is placed at a predetermined position on another cross section of the tunnel. The laser beam emitting device can emit a laser beam toward a predetermined target, and an eye plate with a small hole cut through at a predetermined position in an arbitrary cross section can be placed between the target and the laser beam emitting device. It is known that the linearity of the tunnel can be measured based on whether a laser beam passes through the small hole in the eye plate.

Such laser beam emitting devices, targets,
Laser measurement devices such as eye plates are usually supported on a support stand so that their mounting position and orientation can be finely adjusted.

Conventionally, in such a laser measurement device support device, a pair of parallel long holes are formed in the base frame, and the mounting frame to which the laser measurement device is attached is tightened to the base frame with bolts inserted through each long hole. It is configured to be fixed in position.

[Problems that the invention is intended to solve]

When fine-tuning the position and direction of the laser measurement equipment, loosen the bolts, move the mounting frame by hand, adjust the position of the mounting frame, and at the same time adjust its orientation. This requires tedious and time-consuming work, such as supporting the mounting frame with one hand while tightening the bolts with the other hand. In this way, since the position and orientation of the laser measurement equipment are adjusted by the pair of elongated holes, adjustment of the position of the laser measurement equipment affects the adjustment of the orientation, and conversely, adjustment of the orientation It is relatively difficult to adjust the laser metrology equipment to be in the desired position and facing the desired orientation since the positional adjustment is affected by the positional adjustment. Also, when supporting the mounting frame with one hand and tightening the bolts with the other hand, the position and orientation of the mounting frame may shift, making it difficult to secure it in the correct position and orientation. There are also some problems.

[Means to solve the problem]

The present invention has been made in consideration of the above circumstances, and an object of the present invention is to provide a laser measurement equipment support device that can easily and accurately fine-tune the position of a laser measurement equipment in a short time. shall be.

In the laser measurement equipment support device according to the present invention,
In order to achieve the above object, a slide frame is arranged to be movable up and down, a rotation shaft is arranged in the vertical direction, and the slide frame is moved up and down based on the screwing action with the threaded part of the rotation shaft. An adjustment screw, an elevating swing frame that is pivotally supported on the slide frame and can swing in the vertical direction, and a rotating shaft that is arranged in the vertical direction on the slide frame, and that is based on the screwing action with the threaded part of the rotating shaft. A swing position adjustment screw that adjusts the swing position of the lift swing frame, a horizontal slide frame that can slide laterally at right angles to the swing direction of the lift swing frame, and a rotating shaft that is attached to the lift swing frame. a lateral position adjustment screw that is disposed in a lateral direction perpendicular to the oscillating direction of the elevating and oscillating frame and causes the lateral slide frame to perform the sliding operation based on a threaded action with the rotating shaft screw portion; and the lateral slide. a mounting frame for a laser measurement device that is pivotally supported by the frame and is swingable in the horizontal sliding direction of the horizontal sliding frame; a rotation axis is disposed on the horizontal sliding frame in the horizontal sliding direction;
A lateral swing position adjustment screw is provided that adjusts the lateral swing position of the mounting frame based on a screwing action with the rotating shaft threaded portion.

In the laser measurement device support device configured as described above, the vertical position of the laser measurement device is determined by rotating the vertical position adjustment screw and moving the slide frame up and down by the screwing action of the screw. In addition, to adjust the vertical tilt angle (elevation angle) of the laser measurement device, rotate the swing position adjustment screw after adjusting the vertical position, and adjust the vertical swing position of the vertical swing frame by its threaded action. It is done by doing.

Furthermore, the lateral position of the laser measurement equipment can be adjusted by rotating the lateral position adjustment screw and using its threaded action to slide the lateral slide frame in the lateral direction perpendicular to the swinging direction of the vertical swing frame. be exposed.

After setting the lateral position of the laser measurement device, by rotating the lateral swing position adjustment screw, the laser measurement device mounting frame can be swung in the lateral direction due to its threaded action. Accordingly, the lateral swing position of the laser measurement device can be adjusted.

In this way, the vertical position, vertical swing position, lateral position relative to the vertical direction, and lateral swing position of the laser measurement equipment can be adjusted independently of each other, so the position of the laser measurement equipment can be adjusted independently. , the orientation can be adjusted easily and accurately in a short time.
