Technical Field

[0001] The utility model relates to the technical field of positioning devices for engineering surveying and mapping instruments, in particular to a positioning device for a surveying and mapping instrument used in engineering surveying and mapping. Background Technique

[0002] Engineering surveying and mapping refers to obtaining relevant information of buildings through measurement and mapping. The main work content of engineering surveying and mapping includes various measurement works carried out during the survey, design, construction, and management stages of engineering construction, mostly through total stations. These measurement works directly serve all aspects of various engineering constructions, such as survey, design, construction, installation, completion, monitoring, and operation management. The existing total station consists of a bracket and a measuring device. Among them, the bracket is a retractable bracket, which achieves the purpose of support and positioning through the opening and closing of multiple legs. A measuring device is provided on the bracket, and the measuring device is mostly composed of an electronic theodolite and an eyepiece. Data is observed through the eyepiece and the electronic theodolite. By using digital calculation and optoelectronic technology, high-precision measurement can be achieved. The observed data is processed by a single-chip microcomputer to form the final data, achieving the purpose of surveying and mapping. The opening and closing angle of the bracket of the traditional surveying and mapping instrument is fixed, and the bracket is fixed through the limit groove and the gravity of the body, and the opening and closing angle of the bracket cannot be adjusted according to the actual situation. The legs are mostly fixed and released through the cooperation of a limit knob and a limit block, and precise adjustment cannot be performed. When the observed ground is uneven, the leveling work cannot be carried out quickly and accurately, and it is necessary to pad the legs to carry out the leveling work, which is extremely inconvenient and the positioning effect is poor. Therefore, we propose a positioning device for a surveying and mapping instrument used in engineering surveying and mapping. Content of the Utility Model

The sliders 43 are all sleeved on the outer surface of the screw rods 42. Connecting rods 44 are rotatably connected between the outer surface of the slider 43 and the side of the outer leg 41 close to the center of the mounting base 1. The limit nuts 45 are all threadedly connected to the outer surface of the screw rods 42. The lower end of the upper limit nut 45 is fitted and installed with the upper end of the slider 43, and the upper end of the lower limit nut 45 is fitted and installed with the lower end of the slider 43, providing a basis for adjusting the angle of the legs. The positioning mechanism 4 further includes an adjustment assembly 46. The adjustment assembly 46 includes movable legs 461, inner legs 462, limit holes 463 and limit knobs 464. The movable legs 461 are all slidably connected to the inside of the outer legs 41. The inner legs 462 are all slidably connected to the inside of the movable legs 461. The limit holes 463 are all opened on the side of the inner leg 462 away from the center of the mounting base 1. The limit knobs 464 are all threadedly connected to the lower end of the side of the movable leg 461 away from the center of the mounting base 1. The inner ends of the limit knobs 464 are all fitted and installed with the vertically adjacent limit holes 463. The outer legs 41, the movable legs 461 and the inner legs 462 form an integral leg and are distributed in a triangle, which can quickly retract and extend the legs. The adjustment assembly 46 further includes screw rods 465. The screw rods 465 are all rotatably connected to the middle of the side of the outer leg 41 away from the center of the mounting base 1. Knobs are provided at the upper ends of the screw rods 465.

The bubble level 49 is arranged at the rear side of the upper end of the mounting base 1, which can quickly level the instrument, quickly adjust the deflection angle of the legs, and can also fine-tune the height of a single leg according to the actual situation, so as to quickly level the instrument and improve the positioning efficiency of the surveying instrument.

[0023] The working principle of a positioning device for a surveying instrument used in engineering surveying provided by the present utility model is as follows: When positioning the surveying instrument, first pull out the support leg and reverse the limit knob 464 until the inner end of the limit knob 464 leaves the inside of the limit hole 463. At this time, the inner support leg 462 loses its fixing effect, and the inner support leg 462 can be quickly pulled out. After the inner support leg 462 is pulled out to an appropriate length, rotate the limit knob 464 forward to make the inner end of the limit knob 464 enter the inside of the limit hole 463, and the inner support leg 462 is fixed. Then rotate the knob, and the lead screw 465 also rotates accordingly. As the lead screw 465 rotates, the movable leg 461 slowly moves downward until the total length of the support leg reaches the requirement. At this time, the support leg is in an extended state, and the height of the surveying instrument is initially fixed. Then rotate the lower limit nut 45 to an appropriate position to achieve the purpose of adjusting the deflection angle of the support leg. Rotate the lower limit nut 45, and the lower limit nut 45 moves upward. The upper end of the limit nut 45 presses against the lower end of the slider 43, causing the slider 43 to move upward. As the slider 43 moves upward, the connecting rod 44 presses against the outer support leg 41, causing the outer support leg 41 to deflect outward until the deflection angle of the outer support leg 41 reaches the requirement. Rotate the upper limit nut 45 to make the lower end of the upper limit nut 45 closely adhere to the upper end of the slider 43, and the slider 43 is fixed. The height of the surveying instrument is further fixed. At this time, the entire bracket is in an open state. If it is a hard ground, place the bracket on the ground. The support foot 47 is above the ground and forms a support for the entire bracket. If it is a soft ground, the sharp support foot 47 can be inserted into the ground, and the retaining piece 48 can prevent the support foot 47 from sinking further, making the bracket more stable. After placing the bracket, start leveling. Slightly rotate different knobs to stably change the height of each support foot until the bubble in the bubble level 49 aligns with the crosshair on the surface of the housing, and the surveying instrument reaches a horizontal state. At this time, the positioning work of the surveying instrument is all completed. Then observations can be made through the eyepiece 6 and the electronic theodolite 5. The observed data is processed by the single-chip microcomputer 3 to form the final data, and the surveying work is completed.

[0024] It should be noted that in the above embodiments, the single-chip microcomputer 3 disclosed is an S7-200 single-chip microcomputer, the bubble level 49 is an SM-97 bubble level, and the electronic theodolite 5 is an electronic theodolite. The single-chip microcomputer 3 controls the operation of the electronic theodolite 5 using a method commonly used in the prior art.

[0025] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied to other related technical fields, shall be similarly included in the patent protection scope of the present utility model.
