Detailed Description

The present invention will be described in further detail with reference to the following examples:

a transverse lengthening device for a GPS-RTK centering rod is shown in figures 1 and 2 and comprises the GPS-RTK centering rod, wherein a GNSS receiver machine head connecting piece 1 is fixedly arranged at the top end of the GPS-RTK centering rod, and a tip 5 is fixedly arranged at the bottom end of the GPS-RTK centering rod. The tip 5 stands at a surveying point and finishes surveying and mapping work through a connected GNSS receiver.

As shown in fig. 1, the GPS-RTK centering rod includes a vertical rod 4 and an extension rod 3 disposed in a groove formed on the vertical rod 4, wherein an end of the extension rod 3 is movably connected to the vertical rod 4 through a rotating shaft 6, that is, the extension rod 3 is disposed in the vertical rod 4 in a hidden manner, and the extension rod 3 is disposed in the groove of the vertical rod 4 when not required to be extended, which is not similar to that of a general GPS-RTK centering rod. When a worker is difficult to reach a surveying and mapping point or cannot reach the surveying and mapping point, the extension bar 3 needs to be taken out of the groove of the vertical bar 4 to transversely extend the GPS-RTK, and the GPS-RTK is smoothly placed to a target point to complete measurement.

The tip of extension bar 3 is equipped with detachable handle 12, the setting of handle 12 can make things convenient for the staff to the operation of extension bar 3. When the measurement is finished or the GPS-RTK is not needed to be transversely lengthened, the handle 12 needs to be detached from the end part of the extension bar 3, and the extension bar 3 is placed in the vertical bar 4 under the action of the rotating shaft 6 to realize hidden placement. The handle 12 is attached to the end of the extension bar 3 only when the GPS-RTK needs to be extended transversely for convenient operation.

As shown in FIG. 2, the extension bar 3 comprises a first extension bar 3-1, a second extension bar 3-2 and a third extension bar 3-3 which are movably connected through a clamp 11, wherein the outer wall of the third extension bar 3-3 is slidably connected with the inner wall of the second extension bar 3-2, the outer wall of the second extension bar 3-2 is slidably connected with the inner wall of the first extension bar 3-1, and a handle 12 is detachably connected with the end of the third extension bar 3-3. Such as: the first extension rod 3-1, the second extension rod 3-2 and the third extension rod 3-3 are all arranged in a length of 1 meter, when the distance between a target point and the outside is within 1 meter, the extension of the extension rod 3 is not needed, the extension rod is only required to be taken out of a groove of the vertical rod 4, and the handle 12 is connected; when the target point is between 1-2 meters from the operator, the second wand 3-2 needs to be slidingly withdrawn from the first wand 3-1; when the target point is between 2-3 meters from the operator, the third wand 3-3 needs to be removed from the second wand 3-2. It can be seen that the extension bar 3 can be extended and retracted according to the distance between the target point and the operator to complete the measurement of the target point.

When the target point is in the eminence or the low position of staff, need add the spacing unit of being connected with extension bar 3, montant 4 respectively on original basis, as shown in fig. 2, spacing unit includes that both ends set up the gag lever post 7 of through-hole, set up on montant 4 with spacing hole 2 that the through-hole of gag lever post 7 one end corresponds and set up the locating hole on first extension rod 3-1, the locating hole corresponds with the through-hole of the gag lever post 7 other end, the through-hole passes through the bolt and fixes with spacing hole 2, locating hole respectively. The limiting rod 7 is connected with the extension rod 3 and the vertical rod 4 respectively to achieve the limiting effect.

The positioning holes include a first positioning hole 8, a second positioning hole 9, and a third positioning hole 10. When the limiting rod 7 is connected with the first positioning hole 8, the measurement of a target point at a low position can be completed, when the limiting rod 7 is connected with the third positioning hole 10, the measurement of the target point at a high position can be completed, when the target point is at the flat ground, the measurement of the target point at the flat ground can be completed by connecting the limiting rod 7 with the second positioning hole 9, in the measurement process, the limiting rod 7 not only plays a limiting role, but also has a certain supporting role on the extension rod 3, and the smooth measurement is facilitated.

It can be seen that when the target point to be measured is located opposite to the river channel or at a place inconvenient to arrive, no matter the target point is located at a high position, a low position or a dangerous cliff edge, the device can smoothly complete the test, only the hidden extension rod 3 is taken out of the groove of the vertical rod 4, the extension and retraction are carried out according to the distance of the target point, then the limiting rod 7 is selected according to the height and the low position of the target point to be connected with the first positioning hole 8, the second positioning hole 9 or the third positioning hole 10 to adjust a proper angle, the instrument is erected at a specified position, the centering of the instrument is not required to be ensured, and the coordinate of the target can be accurately determined by utilizing the inertial navigation function of the GPS-RTK.

The extension bar 3 is incorporated into the vertical bar 4 when not used, and has no two types with the common centering bar; when needed, the surveying and mapping can be smoothly completed by taking out the flexible and adjustable angle, the work is fast and convenient, and unnecessary accessories are not needed.

Finally, it should be noted that: the above examples are merely illustrative for the clarity of the present invention and are in no way intended to limit the scope of the invention. It will be apparent to those skilled in the art that many more modifications and variations than mentioned above are possible in light of the above teaching, and it is not intended to be exhaustive or to limit the invention to the precise form disclosed.
