Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a light wave distance meter reflector support device.

Conventional technology As described in Japanese Utility Model Application Publication No. 59-34314, a flange-shaped pedestal is integrated into the lower end of a cylindrical upright column that engages and supports the column of an optical distance meter reflector. A cross scale having an intersection point on the center line of the upright part is provided on the top surface of the pedestal, and the cross scale is placed in alignment with an index such as a cross on the top surface of the index embedded in the ground, road, etc. However, a support device is known in which a flange-shaped pedestal is integrally provided at the lower end of an upright column that supports a column of a light wave distance meter reflector for setting the reflector.

Problems to be Solved by the Invention In the conventional technology in which a brim-shaped pedestal is integrally provided at the lower end of the cylindrical upright column, first, a setting protrusion that is to be butted against the index is attached to the pedestal as a support device. Even if the cross scale on the pedestal matches the cross mark on the index, it is only an indirect result, and it is impossible to directly check whether the center of the pedestal and the center of the index actually match. There is a problem in which the pedestal that supports the light-wave distance meter reflector does not stand stably on the index set by studs in the road, etc. In other words, the pedestal cannot be placed on the index in a very unstable state. There is also the problem that the cross scale on the pedestal and the cross mark on the index do not always match due to different sizes or slopes. There was a problem that the reflector could not be set easily and reliably.

Means to Solve the Problems Therefore, the present invention makes it possible to tilt the light wave rangefinder reflector with respect to an indicator set by implanting a measuring point stud etc. on the ground, road, etc. with an indicator such as a cross on the top surface. In a light wave distance meter reflector support device for supporting and setting, a setting protrusion is provided on the main body of the support device to abut against the indicator, and the indicator is straddled between so that the setting protrusion facing the indicator can be visually recognized. It is an object of the present invention to provide a light wave distance meter reflector support device characterized in that an upright grounding frame portion is provided on the outer periphery of a setting projection.

Function: The reflector support device of the present invention stands upright across the index so that the ground frame portion of the device main body that supports the reflector can visually recognize the setting protrusion.
Point the reflector in the direction of the light wave rangefinder, visually check the setting protrusion provided between the grounding frames, and align it with the intersection of the crosses in the center of the index to complete the setting. Regardless of the direction, the reflector can be set easily and reliably, and the reflector is directly supported by the main body of the support device, which has a grounding frame that straddles the indicator and stands in a stable state. Even if the height is different or there is an inclination, the reflector can be supported in a stable state.
