DETAILED DESCRIPTION

[0030] This part will describe the specific embodiments of the utility model in detail, and the preferred embodiments of the utility model are shown in the drawings, and the drawings are used to supplement the description of the text part in the form of graphics, so that people can intuitively and visually understand each technical feature and the overall technical scheme of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0031] With reference to Figures 1-5 , the utility model embodiment one surveying and mapping engineering with pole, it includes first pole section 1, the side of first pole section 1 is connected with second pole section 2 through hinge 19, the inside of second pole section 2 is slidably connected with sliding block 14 through sliding groove 13, the upper end of sliding block 14 is fixedly connected with third pole section 15, the bottom tenon and groove of first pole section 1 is connected with T-shaped rotating rod 4, the right side outer end of T-shaped rotating rod 4 is fixedly connected with large gear 5, the left side of T-shaped rotating rod 4 is rotatably connected with fixing piece 6, the lower end of fixing piece 6 is fixedly connected with fixed plate 7, the other side of second pole section 2 is fixedly connected with connecting piece 18 through first bolt 20, the lower end of connecting piece 18 is fixedly connected with first pole section 1 through second bolt 21.

[0032] The bottom inner wall of the second pole section 2 is fixedly connected with a second driving motor 17, the output end of the second driving motor 17 is fixedly connected with a threaded rod 16, the outer surface of the threaded rod 16 is threadedly connected with the third pole section 15, the side end of the first pole section 1 is fixedly connected with a circular water level bubble 3, the top of the second pole section 2 is provided with a dustproof cover plate 22, the upper end of the fixed plate 7 is fixedly connected with a supporting plate 9, the rear end of the supporting plate 9 is fixedly connected with a first driving motor 8, the output end of the first driving motor 8 is fixedly connected with a pinion 23, the outer surface of the pinion 23 is meshingly connected with a gear 5, the inside of the fixed plate 7 is slidably connected with a threaded column 10, the lower end of the threaded column 10 is fixedly connected with a bottom plate 12, the outer surface of the threaded column 10 is threadedly connected with a limiting nut 11, and the upper end of the limiting nut 11 is in close contact with the fixed plate 7.

[0033] Working principle: when the pole is used for surveying and mapping engineering, first, the second pole section 2 is folded upwards around the connecting point of the first pole section 1 through the hinge 19 until the second pole section 2 is located at the top position of the first pole section 1. At this time, the connecting piece 18 is fixedly connected with the second pole section 2 through the first bolt 20, and the connecting piece 18 is fixedly connected with the first pole section 1 through the second bolt 21, so as to ensure that the first pole section 1 and the second pole section 2 are stably connected to form a complete pole main body structure. The groove at the bottom of the first pole section 1 is accurately placed on the T-shaped rotating rod 4, so that the first pole section 1 and the T-shaped rotating rod 4 are connected in a mortise and tenon manner. This connection mode can not only ensure the stability of the connection between the pole and the T-shaped rotating rod 4, but also enable the pole to rotate flexibly within a certain range. The first driving motor 8 installed at the rear end of the supporting plate 9 on the fixed plate 7 is started, and the output end of the first driving motor 8 drives the pinion 23 to rotate. Since the pinion 23 is meshingly connected with the gear 5 fixedly connected to the right outer end of the T-shaped rotating rod 4, the rotation of the pinion 23 drives the gear 5 to rotate, thereby driving the T-shaped rotating rod 4 to rotate, and finally realizing the forward and backward angle adjustment of the pole.

[0034] In order to adapt to different surveying and mapping angle requirements, the left and right adjustment of the staff is realized by rotating the limiting nut 11 inside the fixed plate 7. The fixed plate 7 is slidably connected with a threaded column 10, the limiting nut 11 is threadedly connected with the threaded column 10, and the upper end thereof is in close contact with the fixed plate 7. When the limiting nut 11 is rotated, the relative position of the fixed plate 7 on the threaded column 10 is changed, thereby driving the entire staff structure connected with the fixed plate 7 to be finely adjusted in the left and right directions. During the adjustment of the angle of the staff, the circular level bubble 3 fixedly connected to the side end of the first staff section 1 needs to be observed at all times. Whether the staff is in a vertical and horizontal state is judged according to the position of the circular level bubble 3. If the circular level bubble 3 deviates from the center position, it indicates that the staff is not in a vertical state. At this time, the angle of the staff needs to be finely adjusted through the front and rear angle adjustment and the left and right adjustment operation until the circular level bubble 3 is in the center position, so that the staff is in a vertical state, so as to ensure the accuracy of the surveying and mapping data.

[0035] When the actual surveying and mapping work has a higher requirement for the height of the staff, the dustproof cover plate 22 installed at the top of the second staff section 2 is first removed. Then the second driving motor 17 fixedly connected to the inner wall at the bottom of the second staff section 2 is started, and the output end of the second driving motor 17 drives the threaded rod 16 to rotate. Since the threaded rod 16 is threadedly connected with the third staff section 15, when the threaded rod 16 rotates, the third staff section 15 will move linearly upward along the threaded rod 16, so that the third staff section 15 extends out of the second staff section 2, thereby achieving the purpose of increasing the overall height of the staff and meeting the surveying and mapping requirements of different heights.

[0036] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, equivalent changes made in structure, shape and principle according to the present application should be covered within the protection scope of the present application.
