[0026] 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.

[0027] like Figures 1 to 5 As shown, the utility model provides a surveying and positioning device for urban terrain planning, comprising a fixed platform 1, a surveying head 2 is fixedly arranged on the top of the fixed platform 1, a connecting frame 3 is rotatably arranged on the bottom of the surveying head 2, the connecting frame 3 centrally connects a tripod 4 and an adjustment component 5, a tripod 4 is arranged on the outside of the connecting frame 3, and an adjustment component 5 is also included on the left side of the connecting frame 3;

[0028] The adjustment component 5 includes a guide rail 51 fixedly arranged on the outside of the connecting frame 3, a slider 52 is slidably arranged inside the guide rail 51, and the tripod 4 on the left side is rotatably arranged with the slider 52. The tripod 4 on the left side moves inside the slide groove of the guide rail 51 through the slider 52 and is adjusted to different positioning positions. The tripod 4 on the right side is rotatably arranged with the connecting frame 3, and the rotation angle of the tripod 4 is between 0° and 30° to avoid excessive rotation of the tripod 4, which affects the positioning of the surveying head 2. A stretching positioning foot 6 is slidably arranged on the outside of the tripod 4, and the tripod 4 structure is unfolded by stretching the positioning foot 6.

[0029] Specifically, a fastening bolt 53 runs through the interior of the slider 52, and the fastening bolt 53 is spirally arranged with the slider 52, and the top of the fastening bolt 53 is in contact with the guide rail 51. The fastening bolt 53 is rotated to position the slider 52. A baffle 54 is in contact with the left opening of the guide rail 51, and a screw 55 spirally arranged with the guide rail 51 runs through the interior of the baffle 54. The baffle 54 can prevent the slider 52 from derailing.

[0030] Furthermore, a base 7 is fixedly provided at the top of the guide rail 51, a counterweight plate 8 is rotatably provided inside the base 7, a clamping strip 9 that fits the guide rail 51 is fixedly provided at the bottom end of the counterweight plate 8, and a plastic buckle 10 is fixedly provided at the top of the counterweight plate 8, and the counterweight plate 8 can be lifted more conveniently through the buckle 10.

[0031] Furthermore, an elastic plate 12 is fitted on the left side of the counterweight plate 8, and a placement buckle 11 fixed to the guide rail 51 is fixed on the other end of the elastic plate 12. The elastic plate 12 can maintain a tight state on the counterweight plate 8 through elastic deformation.

[0032] Among them, the survey head 2 is the existing technology and will not be described in detail; at the same time, the utility model also includes a power supply, a controller and a switch, which are not the main technical points of this patent and will not be described in detail.

[0033] Working principle and process:

[0034] The staff transports the survey structure to the urban terrain planning area for measurement, and unfolds the tripod 4 structure outside the connecting frame 3 under the fixed platform 1. If the flatness of the ground is poor, the tripod 4 under the guide rail 51 can be stretched by adjusting the component 5. The tripod 4 can be moved inside the guide rail 51 through the slider 52. After moving to different positions, the fastening bolt 53 structure is tightened to position the slider 52 inside the guide rail 51. After the assembly is completed, the tripod 4 under the guide rail 51 is promptly rotated to a flat position, and the tripod 4 structure is flexibly and stably placed to stably support the survey head 2.

[0035] At the same time, some data papers that need to be recorded can be placed on the top of the guide rail 51, and the counterweight plate 8 inside the base 7 is rotated to open, pushing the elastic plate 12 to deform and bend. After the paper is placed on the upper surface of the guide rail 51, the counterweight plate 8 is released, and the elastic plate 12 elastically deforms and resets, pushing the counterweight plate 8 to rotate inside the base 7, and the clamping strip 9 is used to press the surface of the paper for positioning. At the same time, some accessories of the survey head 2 and portable accessories can be hung in the groove of the placement buckle 11, which is more convenient and flexible to use, and at the same time, it is more flexible to observe and record data.
