Description

Technical Field

[0001] The utility model relates to the field of surveying and mapping instruments, in particular to an engineering geological surveying and mapping instrument. Background Art

[0002] Common surveying instruments are fixed to the ground with a tripod, but when the direction needs to be changed, the level and the tripod are fixed, so the entire tripod can only be lifted to change the direction. On the one hand, the tripod needs to be re-leveled, and on the other hand, the angle after the change may be inappropriate and needs to be repeatedly lifted to adjust the angle, which brings a great workload to the surveying personnel. There is an adjustable angle surveying instrument that manually rotates a small knob to drive the internal large diameter gear to rotate to achieve the function of reversing, but the knob is too small and it is easy to slip when used. For example, when operating in northern regions in winter with gloves, the thick gloves make it difficult to feel the knob and pinch it. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1 The engineering geological mapping instrument shown in the figure comprises a level 1 fixed by a tripod, and a rotating assembly 2 is installed between the level 1 and the tripod. Figure 2As shown, the rotating assembly 2 includes a ring gear 3, planetary gears 4, a sun gear 5 and a planet carrier 6. A retaining ring 7 is fixedly connected to the outer periphery of the ring gear 3, and the height of the retaining ring 7 is greater than the height of the ring gear 3. A base plate 8 is rotatably connected to the inner side of the retaining ring 7, and the base plate 8 is located below the ring gear 3. There is a gap between the base plate 8 and the ring gear 3, so that when the retaining ring 7 and the ring gear 3 rotate, the base plate 8 can remain stationary.

[0020] The planetary gears 4 are rotatably connected to the base plate 8 through the planet carrier 6. Each planetary gear 4 corresponds to a planet carrier 6. The planet carrier 6 includes a shaft portion 9 and a transverse portion 10. The shaft portion 9 and the transverse portion 10 are in a cross shape. The planetary gears 4 are fixedly connected to the shaft portion 9 below the transverse portion 10. The lower end of the shaft portion 9 is slidably connected to the base plate 8. There is a gap between the planetary gears 4 and the base plate 8, so that the planet carrier 6 can revolve on the base plate 8, and the planet carrier 6 rotates with the planetary gears 4.

[0021] An intermediate disk 11 is arranged above the retaining ring 7 . The diameter of the intermediate disk 11 is the same as that of the retaining ring 7 , and a gap is formed between the intermediate disk 11 and the retaining ring 7 .

[0022] The upper end of the shaft portion 9 of the planet carrier 6 is rotatably connected to the intermediate disk 11 through the first bearing 12. The first bearing 12 is a plane bearing, which is used to support between the planet carrier 6 and the intermediate disk 11, and allows the planet carrier 6 to rotate relative to the intermediate disk 11. The intermediate disk 11 is provided with a receiving groove corresponding to the upper end of the shaft portion 9 of the planet carrier 6. The upper end of the shaft portion 9 can rotate in the receiving groove, and the planet carrier 6 can form a limit with the planet carrier 6 when it revolves, so that the planet carrier 6 drives the intermediate disk 11 to rotate.

[0023] The sun gear 5 is fixedly connected to the base plate 8 via a sun shaft 13. The upper end of the sun shaft 13 is rotatably connected to the center of the intermediate plate 11. The sun shaft 13 and the intermediate plate 11 are connected via a second bearing 14, which is a radial bearing.

[0024] A base 15 of equal diameter is fixedly connected above the middle plate 11 , and the level 1 is mounted on the base 15 .

[0025] When the angle of the level 1 is changed, the retaining ring 7 is manually rotated. Since the sun gear 5 is fixed, the planetary gear 4 will drive the planetary carrier 6 to perform a deceleration motion in the same direction. The planetary carrier 6 drives the intermediate disk 11 to rotate, thereby driving the level 1 to rotate.

[0026] In order to make the angle of rotation recordable, a vertical convex ridge and a scale are provided on the outer peripheral surface of the retaining ring 7, and a pointer is installed on the outer peripheral surface of the receiving plate 16. The rotation angle of the retaining ring 7 can be seen by the pointer.

[0027] A receiving plate 16 is fixedly connected to the bottom of the base plate 8 . The diameter of the receiving plate 16 is equal to that of the retaining ring 7 . The base plate 8 is used to provide a gap between the retaining ring 7 and the receiving plate 16 , so that the receiving plate 16 does not affect the rotation of the retaining ring 7 .

[0028] The tripod includes a chassis 18 and legs 20. The chassis 18 is connected to the bottom of the receiving plate 16 through an adjustment knob 17. Preferably, there are three adjustment knobs 17, and the upper ends of the adjustment knobs 17 are mounted on the receiving plate 16. The legs 20 are hinged on the chassis 18 through a pin. Figure 3 As shown, the chassis 18 is triangular in shape, and a hinge groove 19 is provided on each side of the triangle, and a pin shaft and a support leg 20 are installed in the hinge groove 19.

[0029] When setting up a tripod on any ground, if the ground is uneven, the three adjustment knobs 17 at the triangle can be used to adjust the angles of the rotating assembly 2 and the level 1 respectively to keep the level 1 level.

[0030] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
