Abstract

<P>PROBLEM TO BE SOLVED: To allow a surveyor to use a surveying instrument to check a point with eyes alone through laser beam irradiation. <P>SOLUTION: A transit or a level is structured such that a laser beam emitted from a laser pointer 6 attached to the tube of a telescope causes the point of a target to move on the horizontal line of a cross within a lens, to be finely adjusted, and to be focused. By incorporating rotary shaft pins into the right and left side surface of the midportion of a staff or a rod between the upper and lower ends thereof and incorporating an overlap into the lower end, the staff or the rod can be made to stand perpendicularly with the rotary shaft pins as points of support. A tripod into which the staff or the rod is inserted is structured such that the ring of an outer cylindrical plate incorporated into a dish on the head of the tripod rotates freely with respect to a body of the head of the tripod. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

In the present invention, when surveying using a conventional level or transit surveying instrument, the point of the target is aligned with the position of the crosshair in the lens, and the position is handed to the assistant on the target side. In this level, the point position can be adjusted with respect to the target. Incorporating a laser pointer adjusts and focuses the laser point on the crosshair in the lens, just as the laser beam is applied to the target from the level. When the target staff or rod is irradiated with the laser beam point adjusted to the crosshairs, the target side assistant can check the laser beam point without a signal from the measurer.
As for the transit, by incorporating a laser pointer into the transit, the laser point is also adjusted and focused on the cross-hair vertical line in the lens as if the laser beam is irradiated from the transit to the target. The laser beam point adjusted to the cross vertical line is a transit that allows the laser beam point to be checked without an operator's signal from the assistant on the target side.
As for the staff and rod of the target object, a weight is incorporated at the lower end so that the staff and rod are vertical, and pins for the rotating shaft are attached to the left and right of the upper and lower middle. As for the tripod that receives the staff and rod, the center column plate ring that receives the pin for the rotation axis of the staff and rod is assembled to the tripod head, and the two rotary shafts attached to the ring of the inner cylinder plate. The pin is built into the outer cylindrical ring. In addition, the outer cylinder plate ring can be freely rotated with respect to the tripod head body, so that the staff and rods inserted into the ring of the middle cylinder plate of the tripod head and received by the pins are staff members. The weight of the lower end built into the rod and the right and left rotating shaft pins attached to the middle and the two rotating shaft pins of the ring of the middle cylinder plate of the tripod head are By making the structure rotatable, the staff and rod can stand vertically, and at the same time, the scale surface of the staff and rod can be directed toward the surveying instrument.
The present invention relates to a surveying instrument capable of such surveying.

Currently, leveling and transiting required a pair of measurers and assistants for surveying, but by attaching a laser pointer that can be adjusted to the target to the surveying instrument and using it, there is only one measurer. However, even with respect to a surveying instrument that can focus on and check the target point, and the staff and rod on the target side, it automatically becomes vertical when installed, and the measurer can check the scale. A surveying instrument that can check the position was desired.

When surveying using the level of a surveying instrument or transit, the measurer and assistant do not perform pairing surveys as in the past, but rather the target on the surveying instrument level or transit telescope tube. By incorporating a laser pointer with a structure that allows fine adjustment to the lens crosshair and focusing, it is possible to irradiate the target point with a laser beam and check the target point. For staff and rods used on the target side, the staff, rods, and tripods are installed in a structure that automatically becomes vertical so that surveying is possible even if there is no assistant. It was thought to be able to work.

Problems to be solved by the invention

Until now, there were the following drawbacks.
When surveying using level or transit, the measurer adjusts and focuses the target point on the horizontal or vertical line of the crosshair in the lens with respect to the target. Since the survey was done by making a signal and exchanging with the receiver, etc., and checking the point position of the target, when surveying, a pair of surveyor and assistant was used for the survey There was a drawback that it can only be surveyed.
Therefore, a laser pointer that can be adjusted to the level and transit is attached, and the point of the target of the laser beam emitted from the laser pointer is adjusted and focused on the horizontal line or vertical line of the crosshair in the telescope lens. It is possible to confirm the point position of the target irradiated with the laser beam with the eyes of the assistant or the measurer himself without having to inform the assistant of the position using a hand signal or a receiver. Yes, you can check the point position. Also, with regard to staff and rod, using a tripod, the structure is such that the staff and rod stand vertically in the tripod head dish and the scale surface of the staff and rod faces the surveying instrument. It is considered that the irradiation position of the laser beam can be visually confirmed with respect to the target and the point position can be checked.

Means to solve the problem

When a level or transit is used, a laser pointer that can be finely adjusted is attached to the telescope tube so that the point position of the laser beam irradiated to the target is on the crosshair in the telescope lens. If the transit surveying instrument has a structure that can move and adjust on the cross vertical line, it can be adjusted and focused on the cross line in the lens and irradiated with a laser beam to the point of the target. Even if an assistant does not communicate with the assistant using a hand signal or a receiver, the assistant can visually check the point position of the laser beam and check it. Further, even one measurer can visually check and check the point position of the laser beam on the target side.
As for the level, a tripod is set up on the target side, the staff and rod stand vertically on the tripod head plate, and the scale surface of the staff and rod is structured so that the scale surface is freely facing the scale surface. Even if there are no personnel, the level and transit surveying instrument is irradiated with the laser beam on the target so that a single measurer can visually check and check the point position of the laser beam on the target. This surveying instrument has a built-in laser pointer that can be fine-tuned and adjusted and focused on the crosshairs.

The invention's effect

By creating a level or transit surveying instrument that incorporates a finely tuned laser pointer, the point position relative to the target is adjusted and focused on the crosshairs in the level or transit telescope lens. By irradiating a laser beam, the measurer can signal the assistant by hand, or exchange the point position using the receiver, and without checking it, the irradiated point position can be confirmed visually and the point can be checked . Further, even the measurer alone can visually check and check the irradiation point of the laser beam on the target side.
As for the staff and rod on the target side, a tripod is used, and the tripod head plate rotates freely from the tripod main body. By using the staff and rod inserted in the head plate, the assistant can easily set the target. You can check the points. Further, it is possible to provide a surveying instrument that can check the point of the target while measuring by the measurer alone.

BEST MODE FOR CARRYING OUT THE INVENTION

Embodiments of the present invention will be described below.
Attach the laser pointer so that it is parallel to the collimation line in the telescope tube of the level or transit so that the objective lens side becomes a fulcrum. On the eyepiece side, an adjustment screw is installed, and the point position of the laser beam emitted from the laser pointer to the target moves on the horizontal line of the crosshair in the lens for the level surveying instrument. A structure that can be quasi-equipped.
The transit surveying instrument has a structure that allows the point position of the laser beam emitted from the laser pointer to move on the crosshair vertical line in the lens to adjust and focus on the target. Then, it is used to visually check and check the point position of the laser beam of the target adjusted or focused on the level or transit crosshairs. As for the staff and rod on the target side, when the tripod head plate is assembled around the center, the rotating shaft pins are incorporated on the left and right sides of the position slightly above the center of the staff and rod so as to be vertical. In addition, a weight is incorporated in the lower end of the staff and rod so that the staff and rod are vertical, while the tripod has a structure in which the outer side of the circular plate rotates freely with respect to the tripod head plate. The outer cylindrical plate outer side has a structure in which two rotary shaft pins on the inner side of the upper and lower cylindrical plates are incorporated.
The inside of the middle cylinder plate has a structure in which a groove for receiving the rotation shaft pin of the staff and the rod is received at two right and left sides with respect to the rotation shaft pin. By installing the pins, the staff and rod will be vertical even if the tripod is not installed horizontally, and the scale surface will also face the direction of the surveying instrument. It can be used as a surveying instrument that makes it possible to confirm and check points with the eye by making a structure that irradiates the daily surface of the rod.
