[0002] The surveying instrument positioning device for engineering surveying is a device used for positioning measurement using surveying instruments in construction projects. At present, there are many surveying instrument positioning devices for engineering surveying on the market, but the general surveying instrument positioning device for engineering surveying needs to adjust the angle and height of the equipment bracket during the positioning measurement of target points at different directions and heights.

[0003] The existing surveying instruments are basically adjusted by manually pulling out the telescopic rod of the surveying instrument. Therefore, the stability of the surveying instrument is relatively poor during the adjustment process, and it will shake during the adjustment, which will cause a relatively large error when measuring a certain point. Especially when the location of the surveying point is relatively far, the error will be even greater, and the measurement accuracy of the surveying instrument is reduced, while the practicality of the positioning device is reduced. Utility Model Content

[0006] Preferably, the adjusting mechanism includes a worm wheel, and one side surface of the worm wheel is rotatably connected to the inner surface of the adjusting box, the other side surface of the worm wheel is fixedly connected to one side surface of the gear through a rotating shaft, the side surface of the worm wheel is meshingly connected with a worm, and the worm is rotatably connected to the adjusting box.

[0007] Preferably, a mounting seat is fixedly connected to the side surface of the support rod, and a support plate is fixedly connected to one side of the mounting seat, and the support plate is symmetrically arranged with the adjustment box.

[0008] Preferably, the lower end of the support rod is rotatably connected to the inside of the base, and the inner side wall of the base and the side surface of the lower end of the support rod are fixedly connected with rubber rings, and the rubber rings are in relative contact.

[0009] Preferably, the upper surface of the base is engraved with angle scale lines, and a pointer is provided above the angle scale lines, and the pointer is fixedly connected to the lower end side surface of the support rod.

[0010] The beneficial effect of the utility model is that the utility model can avoid the worker manually stretching the positioning device of the surveying instrument to adjust the height when adjusting the positioned surveying instrument, thereby avoiding the sliding of the surveying instrument, and reducing the error of the surveying instrument in measuring a point, while improving the accuracy of the surveying result, and further improving the practicability of the positioning device of the surveying instrument.

[0015] 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.

[0016] See also Figure 1-3 As shown, a surveying instrument positioning device for surveying and mapping engineering includes a support rod 1, a telescopic rod 5 is slidably connected inside the support rod 1, and the upper end of the telescopic rod 5 is fixedly connected to the surveying instrument 4, the side surface of the telescopic rod 5 is fixedly connected to a gear rod 10, the upper end side surface of the support rod 1 is fixedly connected to an adjustment box 6, and the adjustment box 6 is communicated with the support rod 1, a gear 14 is provided inside the adjustment box 6, and the side surface of the gear 14 is meshed with the gear rod 10 on the side surface of the telescopic rod 5, one side surface of the gear 14 is connected to an adjustment mechanism, and the lower end of the support rod 1 is provided with a base 9.

[0017] As a technical optimization solution of the utility model, the adjustment mechanism includes a worm gear 12, and one side surface of the worm gear 12 is rotatably connected to the inner surface of the adjustment box 6, and the other side surface of the worm gear 12 is fixedly connected to one side surface of the gear 14 through a rotating shaft 13. The side surface of the worm gear 12 is meshingly connected with 15, and 15 is rotatably connected to the adjustment box 6, which can facilitate the telescopic adjustment of the telescopic rod 5 and the height of the surveying instrument 4, avoiding manual pulling out of the telescopic rod 5 to adjust the angle of the surveying instrument 4.

[0018] As a technical optimization solution of the utility model, the side surface of the support rod 1 is fixedly connected with a mounting seat 3, and one side of the mounting seat 3 is fixedly connected with a support plate 2. The support plate 2 and the adjustment box 6 are symmetrically arranged, which can facilitate workers to fix the display instrument on the support rod 1 for people to observe.

[0019] As a technical optimization solution of the utility model, the lower end of the support rod 1 is rotatably connected to the inside of the base 9, and the inner wall of the base 9 and the side surface of the lower end of the support rod 1 are fixedly connected with a rubber ring 11. The rubber ring 11 is in relative contact and can rotate the support rod 1. At the same time, the support rod 1 can be damped by the rubber ring 11, thereby improving the rotational stability of the support rod 1 and the surveying instrument 4.

[0020] As a technical optimization solution of the utility model, the upper surface of the base 9 is engraved with angle scale lines 7, and a pointer 8 is provided above the angle scale lines 7. The pointer 8 is fixedly connected to the lower end side surface of the support rod 1, so that people can observe the rotation angle of the support rod 1 conveniently.

[0021] The utility model is relatively simple to use. First, the worker places the support rod 1 at the specified position through the base 9. Then the worker can rotate the support rod 1 according to the orientation of the surveying instrument 4. Then the angle of the surveying instrument 4 can be accurately adjusted according to the angle scale line 7 and the pointer 8. When the height of the surveying instrument 4 needs to be adjusted, the worker only needs to rotate the worm 15 inside the adjustment box 6 clockwise, and then the worm 15 will drive the worm wheel 12 to rotate. Then the worm wheel 12 drives the gear 14 to rotate through the rotating shaft 13. At this time, the gear 14 drives the telescopic rod 5 to rise through the gear rod 10, and vice versa, it will drive the surveying instrument 4 and the telescopic rod 5 to descend, thereby adjusting the height of the surveying instrument 4. The worm wheel 12 and the worm 15 have a self-locking function, so the telescopic rod 5 can be prevented from falling due to gravity.

[0022] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
