Description

Technical Field

[0001] The utility model relates to the field of surveying and mapping instruments, in particular to an adjustable geographic information surveying and mapping device. Background Art

[0002] Engineering surveying instruments are a type of measuring instrument. They are various orientation, distance, angle, height, mapping and photogrammetry instruments required for surveying work in the planning, design, construction and management stages of engineering construction. They mainly include theodolites, levels, plane table rangefinders, tachometers, gyrotheodolites, laser measuring instruments, cameras, measuring instruments, plotters, projectors and other instruments. The total station commonly used in the surveying and mapping field currently has the functions of multiple instruments including theodolites and levels, and is usually used for measurement and layout.

[0003] However, the current total station structure for geographic information surveying and mapping still has certain shortcomings during use: when the total station is placed, the lower laser needs to be aimed at the center of the point set in advance on the ground. However, during field surveying, due to strong sunlight, the laser point is difficult to see clearly after installing the frame, the total station, and subsequent fine-tuning, which is inconvenient for surveyors to operate. Secondly, the total weight of the total station and the bracket is generally several kilograms, which is very troublesome for surveyors to move the device between various points. The current total station bracket lacks an auxiliary mobile structure that can be quickly opened and folded.

[0004] Therefore, it is necessary to provide a new adjustable geographic information surveying and mapping device to solve the above technical problems. Utility Model Content

[0005] The technical problem solved by the utility model is to provide an adjustable geographic information surveying and mapping device which has an auxiliary mobile component that can be quickly opened and folded and is convenient for surveying and mapping personnel to check the laser position at any time.

[0006] In order to solve the above technical problems, the utility model provides an adjustable geographic information surveying and mapping device comprising: a base, the side wall surface of the base is rotatably connected to a fixed arm, three fixed arms are evenly distributed around the axis, the bottoms of the three fixed arms are welded with a bottom plate, the surface of the bottom plate facing the base side is connected to a mounting plate by bolts, the mounting plate is vertically arranged, a slide groove is provided on the surface of the mounting plate, a slider is slidably connected inside the slide groove, an inclined surface is provided on the surface of the slider, a limiting hole is provided at the center position of the inclined surface, and the surfaces of the mounting plates on the left and right sides of the slide groove are both plugged into A limit rod is provided, one end of which extends to the inside of the limit hole, a second spring is connected between the limit rod and the mounting plate, a first spring is connected between the slider and the inner wall of the slide groove, the surface of the slider is fixedly connected to a universal wheel through a connecting block, a through hole is provided at the center of the surface of the base, a threaded tube is fixedly connected to the bottom surface of the base outside the through hole, the outer side of the threaded tube is threadedly connected to a fixed tube, the bottom of the fixed tube is connected to an observation outer rod, the inside of the observation outer rod is slidably connected to an observation inner rod, and observation plates are installed on the side wall surfaces of the observation outer rod and the observation inner rod.

[0007] As a further solution of the utility model, a fixing frame is arranged inside the through hole, a limiting tube is slidably connected inside the fixing frame, a fixing bolt is arranged on the top of the limiting tube, an adjusting cap is arranged inside the limiting tube, and an inner hole is opened on the surface of the fixing bolt.

[0008] Through the above technical solution, the mounting base and the total station body are fixed to the base by fixing bolts, and the inner hole on the fixing bolts is used to transmit the lower laser so that the lower laser can illuminate the point fixed on the ground. Due to the strong sunlight in the field environment, the laser is not easy to see clearly, so the structure is provided with a detachable observation outer rod and observation inner rod at the bottom of the base. The user adjusts the bottom position of the observation inner rod through the second screw to let the observation inner rod cover the point, and then views the laser through the transparent observation plate, so that whether it is the rough adjustment in the front or the fine adjustment in the back, it helps the user to accurately position.

[0009] As a further solution of the utility model, the fixing bolt is threadedly connected to a mounting seat, an adjusting bolt is provided at the upper edge of the mounting seat, a total station body is installed at the upper center position of the mounting seat, and a handle is fixedly connected to the top of the total station body.

[0010] Through the above technical solution, the user uses fixing bolts to fix the mounting base and the total station body to the bracket to complete surveying and mapping work such as measurement and layout.

[0011] As a further solution of the utility model, the interior of the fixed arm is slidably connected to an adjusting arm, the bottom of the adjusting arm is fixedly connected to a toe, and the surface of the adjusting arm located above the toe is connected to a pedal via bolts.

[0012] Through the above technical solution, when installing the bracket, first loosen the first screw, then step on the pedal to press down the adjustment arm so that the base is flush with the user's chest, then tighten the first screw to fix the adjustment arm in this position, unfold the bracket, and use the toes to fix the bracket above the point.

[0013] As a further solution of the utility model, an ear plate is welded to the surface of the bottom plate on one side of the mounting plate, a first screw is threadedly connected to the surface of the ear plate, and an end of the first screw abuts against the surface of the adjusting arm.

[0014] Through the above technical solution, the extension length of the adjusting arm inside the fixed arm can be changed through the first screw rod, so that the user can adjust the height of the bracket according to his / her height.

[0016] Through the above technical solution, the total weight of the total station and the bracket is generally several kilograms. It is very troublesome and consumes a lot of effort for surveyors to move the device to various points while holding it. Therefore, in the device, after the user has measured the data of the point, the adjusting arm is folded, and then the pressure plate is stepped on to move the universal wheel under the toe. At this time, the inclined surface of the slider pushes the limit rod to move horizontally until the end of the limit rod is inserted into the limit hole to fix the slider. At this time, the user can move the frame by pulling the universal wheel, which is easy and labor-saving. When the universal wheel needs to be folded later, it is only necessary to push the connecting frame horizontally with the foot to disengage the limit rod from the limit hole, so that the slider can be retracted under the reaction force of the first spring. This structure facilitates the work of surveyors and saves physical effort.

[0017] As a further solution of the utility model, the surface of the observation outer rod is threadedly connected with a second screw rod, and the end of the second screw rod located inside the observation outer rod abuts against the surface of the observation inner rod.

[0018] Through the above technical solution, the extension length of the observation inner rod can be adjusted through the second screw so that the bottom of the observation inner rod can cover the top of the point. At this time, the observation inner rod can block the external sunlight, so that the user can only view the internal laser from the observation plate position. This allows the observer to clearly check whether the laser is at the center of the point at any time.

[0019] Compared with the related art, the adjustable geographic information surveying and mapping device provided by the utility model has the following advantages:

[0020] Beneficial effects:

[0021] 1. In the utility model, the mounting base and the total station body are fixed to the base by fixing bolts. The inner hole on the fixing bolts is used to transmit the lower laser so that the lower laser can irradiate the point fixed on the ground. Since the sunlight is strong in the field environment, it is not easy to see the laser clearly. Therefore, the structure is provided with a detachable observation outer rod and observation inner rod at the bottom of the base. The user adjusts the bottom position of the observation inner rod through the second screw rod so that the observation inner rod covers the point, and then checks the laser through the transparent observation plate. In this way, whether it is the rough adjustment in the front or the fine adjustment in the back, it is helpful for the user to accurately position;

[0022] 2. In the utility model, the total weight of the total station and the bracket is generally several kilograms. It is very troublesome and consumes a lot of effort for surveyors to hold the device and move it to various points. Therefore, in the device, after the user has measured the data of the point, the adjusting arm is folded, and then the pressure plate is stepped on to move the universal wheel below the toe. At this time, the inclined surface of the slider pushes the limit rod to move horizontally until the end of the limit rod is inserted into the limit hole to fix the slider. At this time, the user can move the frame by pulling the universal wheel, which is easy and labor-saving. When the universal wheel needs to be folded later, it is only necessary to push the connecting frame horizontally with the foot to disengage the limit rod from the limit hole, so that the slider can be retracted under the reaction force of the first spring.

[0032] like Figure 1-4As shown, a fixing frame 16 is arranged inside the through hole, a limiting tube 21 is slidably connected inside the fixing frame 16, a fixing bolt 14 is arranged on the top of the limiting tube 21, an adjusting cap 22 is arranged inside the limiting tube 21, and an inner hole 15 is opened on the surface of the fixing bolt 14.

[0033] The mounting base 9 and the total station body 6 are fixed to the base 1 by fixing bolts 14. The inner hole 15 on the fixing bolts 14 is used to transmit the lower laser so that the lower laser can irradiate the point fixed on the ground. Since the sunlight is strong in the wild environment, the laser is not easy to see clearly. Therefore, the structure is provided with a detachable observation outer rod 10 and observation inner rod 11 at the bottom of the base 1. The user adjusts the bottom position of the observation inner rod 11 through the second screw 19 to make the observation inner rod 11 cover the point, and then views the laser through the transparent observation plate 18. This helps the user to accurately position the point regardless of the rough adjustment in the front or the fine adjustment in the back.

[0034] like Figure 1-4 As shown, the fixing bolt 14 is threadedly connected to the mounting seat 9, an adjusting bolt 7 is provided at the upper edge of the mounting seat 9, a total station body 6 is installed at the upper center of the mounting seat 9, and a handle 8 is fixedly connected to the top of the total station body 6.

[0035] The user uses the fixing bolts 14 to fix the mounting base 9 and the total station body 6 to the bracket to complete surveying and mapping work such as measurement and layout.

[0036] like Figure 1-4 As shown, the interior of the fixed arm 2 is slidably connected with the adjusting arm 3, the bottom of the adjusting arm 3 is fixedly connected with the toe 4, and the surface of the adjusting arm 3 located on the upper side of the toe 4 is connected with the pedal 5 through bolts.

[0037] When installing the bracket, first loosen the first screw 12, then step on the pedal 5 to press down the adjustment arm 3 so that the base 1 is flush with the user's chest, then tighten the first screw 12 to fix the adjustment arm 3 in this position, unfold the bracket, and use the toes 4 to fix the bracket above the point.

[0038] like Figure 1-4 As shown, an ear plate is welded on the bottom plate surface on one side of the mounting plate 25 , and a first screw rod 12 is threadedly connected to the surface of the ear plate. The end of the first screw rod 12 abuts against the surface of the adjusting arm 3 .

[0039] The first screw rod 12 can be used to change the extension length of the adjusting arm 3 inside the fixed arm 2, so that the user can adjust the height of the bracket according to his or her height.

[0040] like Figure 1-4As shown, a pressure plate is welded on the side wall surface of the slider located on the upper side of the universal wheel 13 , and a connecting frame 27 is fixedly connected between the two limiting rods 24 , and the connecting frame 27 is located on the outer side of the universal wheel 13 .

[0041] The total weight of the total station and the bracket is generally several kilograms. It is very troublesome and consuming a lot of effort for surveyors to hold the device and move it to various points. Therefore, in the device, after the user has measured the data of the point, the adjustment arm 3 is folded, and then the pressure plate is stepped on to move the universal wheel 13 below the toe 4. At this time, the inclined surface 28 of the slider pushes the limit rod 24 to move horizontally until the end of the limit rod 24 is inserted into the limit hole 29 to fix the slider. At this time, the user can move the frame by pulling the universal wheel 13, which is easy and labor-saving. When the universal wheel 13 needs to be folded later, it is only necessary to push the connecting frame 27 horizontally with the foot to disengage the limit rod 24 from the limit hole 29, so that the slider can be retracted under the reaction force of the first spring 23. This structure facilitates the work of surveyors and saves physical effort.

[0042] like Figure 1-4 As shown, the surface of the observation outer rod 10 is threadedly connected with a second screw rod 19 , and the end of the second screw rod 19 located inside the observation outer rod 10 abuts against the surface of the observation inner rod 11 .

[0043] The extension length of the observation inner rod 11 can be adjusted by the second screw 19 so that the bottom of the observation inner rod 11 covers the top of the point. At this time, the observation inner rod 11 can block the external sunlight, so that the user can only view the internal laser from the position of the observation plate 18. This allows the observer to clearly check whether the laser is at the center of the point at any time.

[0044] The working principle of an adjustable geographic information surveying and mapping device provided by the utility model is as follows:

[0045] Step 1: Fix the mounting base 9 and the total station body 6 to the base 1 through the fixing bolts 14. The inner hole 15 on the fixing bolts 14 is used to transmit the lower laser so that the lower laser can irradiate the point fixed on the ground. Since the sunlight is strong in the field environment, the laser is not easy to see clearly. Therefore, the structure is provided with a detachable observation outer rod 10 and observation inner rod 11 at the bottom of the base 1. The user adjusts the bottom position of the observation inner rod 11 through the second screw 19 so that the observation inner rod 11 covers the point, and then checks the laser through the transparent observation plate 18. In this way, whether it is the rough adjustment in the front or the fine adjustment in the back, it is helpful for the user to accurately position;

[0046] The second step: The total weight of the total station and the bracket is generally several kilograms. It is very troublesome and consuming a lot of effort for surveyors to hold the device and move it to various points. Therefore, in the device, after the user has measured the data of the point, the adjusting arm 3 is folded, and then the pressure plate is stepped on to move the universal wheel 13 below the toe 4. At this time, the inclined surface 28 of the slider pushes the limit rod 24 to move horizontally until the end of the limit rod 24 is inserted into the limit hole 29 to fix the slider. At this time, the user can move the frame by pulling the universal wheel 13, which is easy and labor-saving. When the universal wheel 13 needs to be folded later, it is only necessary to push the connecting frame 27 horizontally with the foot to disengage the limit rod 24 from the limit hole 29, so that the slider can be retracted under the reaction force of the first spring 23. This structure facilitates the work of surveyors and saves physical effort.
