The shortcut point lofting device is matched with a total station for use, and when lofting the point location, the point location is determined within a small range, for example, within the range of 20cm by 20cm through the rough lofting equipment 1. The rough sampling device 1 may employ instruments such as DGPS, RTK, etc., wherein the RTK is the most effective. An RTK (Real-time kinematic) carrier phase differential technology is a differential method for processing carrier phase observed quantities of two measuring stations in Real time, and the carrier phase acquired by a reference station is sent to a user receiver for difference solving. The RTK station spacing is 30 kilometers, and the best plane precision can reach 1-2 cm.

After the initial range of the point location is determined, the direction of the point location is determined by using a total station, the tripod is placed in the range determined by the rough lofting equipment 1 for leveling, the center of the adjustable range of the prism 3 is approximately ensured to be positioned near the lofting point location of the rough lofting equipment 1, the prism 3 can basically reach any position in the range, then the position of the prism 3 is adjusted by using the prism fine adjustment mechanism 5 until the point location is accurately reached, and the point location lofting is completed by marking after the prism 3 is thrown. The tripod 2 and the prism fine adjustment mechanism 5 are integrated, the tripod 2 is leveled to ensure that the prism fine adjustment mechanism 5 is in a leveling mode state, the centering and leveling of the tripod 2 are not needed to be carried out when the prism 3 is adjusted, even if workers with insufficient working experience can complete the adjustment and lofting of the prism 3, and the working efficiency of personnel is greatly improved. The prism fine adjustment mechanism 5 is preferably connected with the tripod 2 in a detachable connection mode, and is assembled when being used again, so that the transportation is convenient.

The prism fine adjustment mechanism 5 is a key for adjusting the position of the prism 3, and comprises a transverse rod 51 arranged along a first horizontal direction and a longitudinal rod 52 arranged along a second horizontal direction, wherein the first horizontal direction and the second horizontal direction are crossed, namely the first horizontal direction and the second horizontal direction are not parallel, on the basis, the longitudinal rod 52 is arranged in a reciprocating translation mode along the first horizontal direction and the prism 3 in a reciprocating translation mode along the second horizontal direction, and the position of the prism 3 can be adjusted through superposition of displacement in the two directions. Although the first horizontal direction intersects the second horizontal direction, that is, the prism 3 can be adjusted to any position within the range, preferably, the first horizontal direction and the second horizontal direction are perpendicular to each other, which can improve the adjustment efficiency and reduce the adjustment difficulty.

The prism fine adjustment mechanism 5 is specifically provided in various ways, wherein the longitudinal rod 52 is moved in the first horizontal direction and the prism 3 is moved in the second direction. For the movement of the longitudinal rod 52, in addition to the sliding fit between the longitudinal rod 52 and the transverse rod 51 along the first direction, the expansion and contraction of the transverse rod 51 along the first direction can also realize the movement of the longitudinal rod 52 along the first direction, and for the movement of the prism 3, the prism 3 itself can also move along the second direction, and also the movement of the longitudinal rod 52 along the second direction can be realized.

Fig. 2 to 4 show an embodiment of adjustment of the prism 3 according to the present invention, the horizontal rod 51 is provided with an adjusting connector 54, the adjusting connector 54 is in sliding fit with the horizontal rod 51 along a first horizontal direction, and the longitudinal rod 52 is in sliding fit with the adjusting connector 54 along a second horizontal direction. Fig. 2 shows the initial state of the prism fine adjustment mechanism 5, and point a is the exact position of the point location, and the lofting of the point location can be realized by moving the prism 3 to point a. For adjustment, as shown in fig. 3, the adjustment link 54 is slid along the transverse bar 51 to bring the longitudinal bar 52 to point a, as shown in fig. 4, and then the longitudinal bar 52 is slid in the second direction to bring the prism 3 to point a. The sliding fit of the adjusting connector 54 with the transverse rod 51 and the longitudinal rod 52 can be achieved by referring to various sliding fit methods, such as sleeve insertion sliding fit, slotted or holed sliding fit, etc., and the prism 3 and the longitudinal rod 52 do not need to slide relatively, so that the prism 3 can be fixed on the longitudinal rod 52.

Fig. 5 to 7 show another embodiment of the adjustment of the prism 3 according to the present invention, wherein the longitudinal rod 52 is slidably engaged with the transverse rod 51 along a first horizontal direction, and the prism 3 is slidably engaged with the longitudinal rod 52 along a second horizontal direction. Fig. 5 shows the initial state of the prism fine adjustment mechanism 5, and the point a is the exact position of the point location. In adjustment, as shown in fig. 6, the prism 3 is aligned with the point a by sliding the longitudinal rod 52 along the transverse rod 51, as shown in fig. 7, and then the prism 3 is slid along the longitudinal rod 52, so that the prism 3 reaches the point a. The sliding fit of the longitudinal bar 52 with the transverse bar 51 and the prism 3 with the longitudinal bar 52 can be referred to the sliding fit described above.

The above two embodiments are only examples of adjusting the position of the prism 3, and in the actual use process, the exact point position to be reached by the prism 3 is unknown, which is equivalent to the point a being unknown, so that it is often necessary to adjust the prism 3 multiple times to reach the correct point position.

After the prism 3 is adjusted in position, a pointing mark is required, and a pointing mechanism 4 may be connected to the prism 3 in order to improve pointing accuracy. The pointing mechanism 4 may be a line hammer or a laser pointer, etc. Wherein, the laser pointing instrument is most convenient and has the highest pointing accuracy.

The fine adjustment range of the prism 3 is limited, and in some cases, the tripod 2 may be inaccurately erected and the prism 3 may not reach the correct point. For this purpose, it is preferable that a connection ring 53 is provided at one end of the cross bar 51, and the connection ring 53 is rotatably connected to the tripod 2 about a vertical rotation axis. After the tripod 2 is erected, the whole prism fine adjustment mechanism 5 can rotate around the tripod 2 by rotating the connecting ring 53, so that the adjustable range of the prism 3 is greatly increased. When the prism fine adjustment mechanism is used, the prism fine adjustment mechanism 5 can be rotated to a better direction, and then the prism 3 is adjusted.
