DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pole device for displaying an antenna device and performing surveying by a positioning system using a GPS satellite, and a method for adjusting the GPS surveying pole device. The present invention relates to a pole device for GPS surveying which is most suitable for surveying on uneven mountaintops or the like such as a triangulation survey, in addition to many obstacles such as electric wires and trees, and a method of adjusting the pole device for GPS surveying.

[0002]

2. Description of the Related Art A so-called GPS (global positioning system) positioning system that receives a plurality of microwaves transmitted from an artificial satellite and analyzes the data to receive the microwaves arrives at a measurement point. Precise installation of an antenna device for measurement is indispensable. The antenna device in the GPS positioning system is used by being fixed to a tripod or the tip of a pole. Particularly, in a mountainous area or a mountain top, a tree often interferes, so a pole as high as possible and a fixing device for the pole are required.

Conventionally, the above-mentioned pole is provided with a plurality of stages of a pipe extending and retracting type so that it can be easily transported, and a metal fitting for detachably fixing an antenna device is provided at a tip thereof.
At the base end, there is a sword point (stone foot) defined by a triangular point. In addition, a tripod is used as the fixing device, and the tripod includes a leg stand on which the pole is erected and inserted, and durable telescopic legs rotatably supported on three sides of the leg stand.

[0004] A pole having an antenna device attached to its tip is disposed on a triangular point by a tripod, and is extended to a required height, and a stay wire attached to a key point is locked to an anchor driven into the ground. The structure is supported by being stretched. Since the pole itself does not have a collimation device for checking the coincidence of the antenna displayed above the measurement point, the transit is arranged in two directions perpendicular to the pole, and the stay is instructed from both directions. It is necessary to turn or turn the turnbuckle provided in the middle of the wire to tension or relax the stay wire, respectively, to perform collimation to check the coincidence between the triangular point and the antenna.

[0005]

However, this conventional method has the following problems. 1. In other words, since the pole itself does not have a collimation device, it is necessary to always carry two sets of the transit and the tripod on which the transit is to be installed, and always carry such a heavy object even in a mountainous area with poor scaffolding. Therefore, there has been a problem that labor is extremely heavy and extra personnel are required in addition to measurement personnel. 2. In addition, installation and adjustment work of the transit itself is also required, which is troublesome, and when it is necessary to set up the transit on a slope and perform collimation work, installation and collimation work is very difficult, There were problems such as being dangerous. 3. The tripods used for fixing the poles are large, sturdy and reliable, and the weight increases accordingly.
However, when the pole height is increased, fixing with a tripod alone is insufficient, so that it is necessary to hold the stay with a stay wire, and there is a problem in that extra transportation is required as much as the tripod is used. 4. In the case of using a foot for reference, at least the tip of this foot is made of metal. there were.

The present invention has been made to solve such a conventional problem, and its object is to provide:
Pole device for GPS surveying and its GPS, which are easy to carry in and install on site, and easy and precise to collimate the antenna device with respect to the triangular point, and particularly suitable for surveying at uneven mountain tops such as triangular point surveying An object of the present invention is to provide a method of adjusting a survey pole device.

Further, the present invention makes it possible to handle the antenna device more stably than the conventional pole even if the height is raised, in addition to making it easy to handle as the maximum diameter equivalent to that of the conventional pole. GP that does not hurt the triangle point even if it is placed on a point
An object of the present invention is to provide an S surveying pole device.

[0008]

As a means for achieving the above object, in the GPS survey pole device according to the first aspect of the present invention, a plurality of pipes having different thicknesses are inserted one after another in a multilayer shape and are freely expandable and contractable. A stopper is provided for engaging and disengaging the pipes at the seam position, a stopper for an upright stay wire is provided at an upper end of the pipe at an appropriate step position, and an upper end of the minimum diameter pipe is further provided. Is provided with a mounting bracket for detachably fixing the antenna device, and a pole body provided with a stone protrusion at the lower end of the largest diameter pipe; one end of the pole body and centered on the one end side axis. A laser beam emitting device for vertically emitting a laser beam from a plurality of positions on the concentric circle toward the other end of the pole body; and a concentric circle on the other end side of the pole body and centered on the axis of the other end. A light receiving and displaying device for a laser beam indicating a concentric circular position; and a stay wire having a length adjusting device, one end of which is connected to the locking portion of the pole body and the other end of which is fixed to the ground. The configuration was adopted.

In this configuration, the pole body standing upright on the triangular point is held in an upright state by stretching the stay wire locked at an appropriate step position with an anchor driven into the ground. Then, collimation of the pole body emits laser beams at a plurality of concentric circles in the vertical direction from one end side of the pole body, receives light at the other end side, and the spot deviates from the concentric position on the other end side. In this case, the stay wire length of each part is adjusted by tightening or loosening a length adjusting device, for example, a turnbuckle, until the spot coincides with any position of the concentric circle.

According to a second aspect of the present invention, there is provided a GPS surveying pole apparatus, wherein a level for adjusting the verticality of a lower end side of the pole body is provided on the side of the pole of the pole body of the GPS surveying pole apparatus according to the first embodiment. Configuration.

In this configuration, before extending the pole body,
First, the pole main body is temporarily fixed with a stay wire in a state where the feet are arranged on the triangular points. Thereafter, by taking the verticality of the lowermost pipe with a spirit level and then extending the other pipes, the pole body can be easily erected vertically.

According to a third aspect of the present invention, the light receiving and displaying device of the first or second aspect of the present invention is configured such that a white disk concentric circle is provided on a black disk.

In this configuration, since the laser beam reflects well only on the concentric circles, even if the pole body is long, that is, the light receiving and displaying device is at a high position, and even if the spot is narrowed down, it can be clearly confirmed. Therefore, accurate collimation can be performed.

[0014] In the GPS survey pole device according to the fourth aspect, the foot of the GPS survey pole device according to the first, second or third aspect is formed of a hard plastic.

In this configuration, the pole body can be erected on the triangular point on the stone without damaging the triangular point with the stone foot. In addition, accurate surveying can be easily performed.

According to a fifth aspect of the present invention, there is provided a GPS survey pole apparatus, wherein the pipe of the GPS survey pole apparatus according to the first, second, third or fourth aspect is formed of carbon fiber reinforced plastic.

In this configuration, the pole body can be provided lighter than the glass fiber reinforced plastic or aluminum after securing the strength equal to or higher than that of the glass body. Therefore, the pole body is carried by hand such as a mountaintop or a slope having a poor scaffolding. It can be easily carried in various places. In addition, since the handling can be simplified, the surveying can be performed in a short time.

In the method for adjusting a GPS surveying pole device according to a sixth aspect of the present invention, a long GPS surveying pole is erected on a reference point with a stay wire, and one end of the GPS surveying pole is provided. A laser beam is emitted in a vertical direction from a position distant from the axis of the part by a set distance, and light is received on a display surface indicating the set distance on the other end side of the GPS surveying pole and centered on the axis of the part. Is displayed, and the shift amount of the light receiving display with respect to the concentric circle is corrected by adjusting the length of the stay wire to collimate the GPS survey pole.

In this configuration, the collimation of the pole body erected on the triangular point is such that a laser beam emitted vertically from one end of the pole body is received at the other end, and the spot is set at the other end. Since the correction target is to deviate from the display position, there is no need for two sets of transit and a tripod for mounting it, greatly reducing the overall weight and simplifying handling, and also in dangerous places. This eliminates the need for installation and collimation work for the safety work, and also eliminates the need for extra transits, tripods, and other personnel for transportation, thereby reducing costs.

The pole body 1 includes nine pipes having sequentially different inner and outer diameters, ie, a first pipe 11, a second pipe 12,... An eighth pipe 18, and a ninth pipe 19. In the present embodiment, all the pipes are formed by molding into a cylindrical body with carbon fiber reinforced plastic. In the figure, 20a,

Reference numeral 25 denotes a bolt shaft of a specified size protruding from the upper end of the ninth pipe 19 forming the uppermost end of the pole body 1, and serves as a mounting bracket for detachably fixing the antenna device 5. Things. 26 is the first stage pipe 1
1 is a lower component, and a lower end thereof is made of a hard foot 27 made of hard plastic (for example, hard vinyl chloride or nylon).
Is provided. 27a is the point of the sword. 28 is 1
A ring-shaped locking portion rotatably inserted at each of the upper ends of the pipes at every other stage from the second stage pipe 11 and the pipes,
Four connecting holes 28a for the stay wire are equally formed on the concentric circle.

The laser beam emitting device 2 uses a light receiving and displaying device 3 and a stay wire device 4 to be described later as an integral unit to enable collimation by the present GPS survey pole device itself. A pencil-type firing unit 29 having a power supply installed therein, and the firing unit 29 is rotated around the axis of the pole body 1 (radius 10 cm in the present embodiment).
A rotating arm portion 30 to be rotated, and a level 31 for emitting a laser beam in parallel with the axis of the pole body 1 to project the horizontality of the rotating arm portion 30 and to emit the laser beam. The part 29 is mounted perpendicular to the rotating arm part 30.

The light receiving and displaying device 3 is formed of a black plastic disk, and has a set hole 32 at the center thereof for fitting the bolt shaft 25 without looseness. On the lower surface side of the board, crosses 33 orthogonal to each other at the set holes 32 and five concentric circles 34, 35,... 38 are drawn at equal pitches (1 cm pitch in the present embodiment) by white lines. . In this case, an intersection mark 39 is drawn at the intersection of the center concentric circle 36 and the cross 33 among the concentric circles.

In the stay wire device 4, the pole body 1 is erected and fixed without using a tripod. A turnbuckle 41 is disposed in the middle of a flexible stainless steel wire 40, and the ring-shaped member is provided on the tip end side. A lower hook 44 is provided at the rear end side of the lower hook 44 for locking to an anchor 43 which is provided in the mountain area.
have.

Next, a collimation adjustment method of the GPS survey pole apparatus A will be described. First, with the pole body 1 reduced, the stone foot 27 is placed at a triangular point, and the shortest stay wire device 4 is connected to the lowermost ring-shaped locking portion 28. After being connected and temporarily fixed to the driven anchor 43, the light-receiving display device 3 and the antenna device 5 are mounted on the upper end of the pole body 1 via the bolt shaft 25 provided there. In this case, the light-receiving display device 3 is fixed such that the intersection marks 39 face the directions of the anchors 43, respectively. In this state, while looking at the level of the rotating arm unit 30 with the level 31 of the laser beam emitting device 2,
By adjusting the length of the wire with the turnbuckle 41, the rotating arm 30 is kept horizontal. by this,
The verticality of the pole body 1 is adjusted.

Next, the pipe is pulled upward from the pipe on which the light receiving and displaying device 3 and the antenna device 5 are mounted, that is, the pipe 19 which is the uppermost end of the pipe main body 1.
The stay wire device 4 is connected to the ring-shaped engaging portion 28 at an appropriate position (in the present embodiment, at the ninth and fifth stages) and is extended. It should be noted that the stay wire device 4 may be increased or decreased depending on the strength of the wind. When the upper pipes are pulled out of the individual pipes until the retaining stepped portions 20a and 20b come into contact with each other, the stoppers 22 project from the locking holes 21 to securely fix the pipes to each other.

After all the pipes have been pulled out (in this embodiment, the total height is approximately 12 m), each stay wire device 4
Is temporarily fixed to the anchor 43. In this state, the power of the emission unit 29 is turned on, and the laser beam is emitted toward the light receiving and displaying device 3. In this case, if the spot by the laser beam is displaced from the concentric circle 36 of the light-receiving display device 3, the turnbuckles of the stay wire device 4 in the displaced direction are rotated or reversely rotated to relax or tension the wire. Thus, the spot is made to coincide with the intersection mark 39. The confirmation of the spot can be more easily performed by using small binoculars.
After the spot coincides with one of the intersection marks 39, the rotating arm 30 is rotated by 90 degrees, and the direction is adjusted this time. After finishing this adjustment, it is preferable to check the accuracy by making a full circle around the spot. After collimating the pole body 1 in this manner, the power of the antenna device 5 is turned on and the receiving operation is started. In the pole unit A for GPS surveying in the present embodiment, since the pole body 1 is made of carbon fiber reinforced plastic, lightning is generated from other materials, for example, those formed of glass fiber reinforced plastic. Care must be taken to avoid lightning damage. In this case, if lightning is likely to occur, remove it as soon as possible and reassemble after lightning has passed. Since the assembly and collimation of the pole body 1 can be performed very easily, this is very effective when weight reduction and simple collimation are required, such as for surveying in a remote and steep mountainous area.

As described above, G in the present embodiment
In the pole apparatus A for PS survey, the collimation by the laser beam can be easily and precisely performed by a simple procedure because the point and the misalignment thereof can be easily confirmed even when the pole height is as high as 12 m. Further, since the pole body 1 is formed of carbon fiber reinforced plastic, it is possible to secure sufficient strength and reduce the weight. Since everything is fixed by the stay wire device 4, a tripod becomes unnecessary, and the weight can be reduced accordingly. Since the pole body 1 is entirely formed of hard plastic, even if the pole body 1 is directly mounted on a triangular point, the important triangular point is not damaged. Since the collimation of the pole body is performed by the laser beam emitting device 2 and the light receiving and displaying device 3 provided on the pole body, no transit, tripod for mounting the transit, transportation, installation and adjustment of the transit itself, and extra personnel are unnecessary. Thus, it is possible to simplify the surveying and reduce the cost while reducing the total weight. In addition, since it is not necessary to perform collimation by installing the transit in a place with poor scaffolding, the work can be performed safely.

Although the embodiment of the present invention has been described above, the specific configuration of the present invention is not limited to this embodiment, and there are design changes and the like within a range not departing from the gist of the invention. This is also included in the present invention.

For example, in the embodiment, the stopper has been described as projecting with a spring. However, the present invention is not limited to this.
A through hole may be provided between pipes, and a pin may be inserted when the holes match when the pipe is drawn.

The material of the pipe body may be carbon fiber reinforced plastic, glass fiber reinforced plastic or aluminum, or a mixture of these.

The internal structure of the pipe body is optional.

Launching unit 2 in laser beam emitting device 2
Although 9 is mounted vertically on the rotary arm 30, the lower portion of the firing portion 29 may be made heavy and the upper portion may be supported by an automatic centripetal bearing 50 as shown in FIG. In this case, since the laser beam is always emitted in the vertical direction as shown in the order of (a) and (b), the laser beam can be collimated only by the spot on the light receiving and displaying device 3 and the level does not need to be used. Further, in this case, if it is formed precisely, there is an advantage that if only one point in the light receiving and displaying device 3 is matched, collimation can be performed with this and the arm does not need to be rotated.

In the GPS survey pole device according to the fifth aspect, since the above configuration is adopted, it is necessary to pay attention to the occurrence of lightning from other materials, for example, those formed of glass fiber reinforced plastic and avoid lightning damage. However, in this case, assembling and collimating the pole body can be performed very easily, so if lightning is likely to occur, remove it early and reassemble after lightning has left When the weight reduction and the simplicity of collimation are extremely important, for example, in surveying in a distant and steep mountainous area, the effect of being very effective is obtained.
