Description

Technical Field

[0001] The invention belongs to the field of surveying technology, in particular to a geographic information surveying and mapping device. Background Art

[0002] Surveying and mapping instruments, to put it simply, are instruments and devices designed and manufactured for surveying and mapping operations, such as data collection, processing, and output. They are instruments for various orientation, distance, angle, height, mapping, and photogrammetry required for surveying work during the planning, design, construction, and management stages of engineering construction. When conducting geographic information surveying and mapping, total stations are often used to measure horizontal angles, vertical angles, distances (slant distances, horizontal distances), and elevation differences.

[0003] The existing technology also proposes some solutions. For example, a Chinese patent with the announcement number CN218001069U discloses a new type of surveying and mapping geographic information engineering surveying frame, which includes a mounting base and a balancing base. A surveying instrument is rotatably provided on the top of the mounting base, and a connecting plate is fixedly connected to the outer side of the mounting base. The end of the connecting plate away from the mounting base is rotatably connected to a support leg. By observing the spirit level, it can be determined whether the balancing base is in a horizontal state, so the height of the straight plate on one side from the ground can be adjusted according to the tilt state of the spirit level until it is adjusted to a horizontal state, thereby achieving the purpose of facilitating the adjustment of the horizontal position and being convenient to use on uneven ground.

[0004] Although the above technical solution can facilitate the adjustment of the horizontal position, there are still other problems in its specific use. Current geographic information surveying and mapping equipment mostly uses adjustable brackets and horizontal calibration mechanisms to improve measurement accuracy. The surveying head, as a core component, is usually exposed above the bracket when not in operation, and is easily eroded by harsh environments such as wind, sand, rain, and hail. Especially in sandstorms, acid rain or high ultraviolet areas, precision components such as lens coatings and sensors are prone to aging or scratches, affecting the normal use of the surveying and mapping equipment.

Two sets of shielding plates 3 are slidably provided on the upper end surface of the protective seat 1, and the shielding plates 3 can slide on the upper end surface of the protective seat 1. A cavity adapted for the information mapping head 2 is provided inside the protective seat 1, and a reciprocating cylinder 4 is installed inside the protective seat 1, and the telescopic end of the reciprocating cylinder 4 contacts the bottom of the information mapping head 2;

[0034] When working, in the initial state, that is, when the information mapping head 2 is not in use, the information mapping head 2 is located inside the protective seat 1, and the two sets of shielding plates 3 close the opening above the protective seat 1. Figure 1 and Figure 2 When the geographic information mapping device needs to be used, the telescopic end of the reciprocating cylinder 4 drives the information mapping head 2 to move upward, and the two sets of shielding plates 3 will slide above the protective seat 1, so that the opening of the protective seat 1 is opened, and then the information mapping head 2 will move to the adjacent Figure 4 The position shown in the figure is such that the staff can realize geographic information mapping and processing through the information mapping head 2. Such a design can protect the information mapping head 2 when not in use, solving the problem that the information mapping head 2 is exposed to the outside in the prior art and may be damaged by objects hitting it. It is also not easily eroded by harsh environments such as wind, sand, rain, and hail, and avoids the problem that precision components such as lens coating and sensor are prone to aging or scratching in sandstorms, acid rain or high ultraviolet areas.

[0035] like Figures 2 to 6 As shown, a driven gear 5 is rotatably provided inside the protective seat 1, an eccentric shaft 501 is mounted on the outer circumference of the driven gear 5, a connecting bracket 6 is rotatably provided at the end of the eccentric shaft 501 away from the driven gear 5, the end of the connecting bracket 6 is hinged to the lower end surface of the shielding plate 3, and a driving unit is provided at the telescopic end of the reciprocating cylinder 4, which is used to drive the driven gear 5 to rotate;

[0036] During operation, when the telescopic end of the reciprocating cylinder 4 drives the information mapping head 2 to move upward, the telescopic end of the reciprocating cylinder 4 will drive the driven gear 5 to rotate through the driving unit, and the driven gear 5 will drive the eccentric shaft 501 on its outer surface to rotate, and the eccentric shaft 501 will drive the shielding plate 3 to move through the hinged connecting bracket 6, so that the shielding plates 3 on both sides will move away from each other. When the information mapping head 2 moves to the adjacent Figure 4 After reaching the position shown, the operation of the reciprocating cylinder 4 is stopped, and the information surveying and mapping device can be used without the need for manual removal by staff, which is convenient to operate.

[0037] The driving unit includes a fixed bracket 7, which is installed on the telescopic end of the reciprocating cylinder 4. The fixed bracket 7 includes two groups and is symmetrically arranged relative to the information mapping head 2. A tooth plate 8 is installed on the upper end of the fixed bracket 7, and the tooth plate 8 is meshed and connected with the driven gear 5; when working, when the telescopic end of the reciprocating cylinder 4 drives the information mapping head 2 to move upward, it will simultaneously drive the fixed bracket 7 to move upward, and the fixed bracket 7 drives the tooth plate 8 to move upward, and the tooth plate 8 will drive the driven gear 5 meshed with it to rotate, and the driven gear 5 will drive the baffle 3 to move through the above-mentioned connecting bracket 6, thereby achieving the effect of automatic opening of the baffle 3.

[0038] Two sets of articulated frames 9 are provided below the shielding plate 3, and the two sets of articulated frames 9 are respectively hinged to the ends of the connecting brackets 6 on both sides of the driven gear 5; when working, the ends of the connecting brackets 6 are hinged to the bottom of the shielding plate 3 through the articulated frames 9, which can facilitate the connecting bracket 6 to pull the shielding plate 3 to move above the protective seat 1 through the articulated frames 9, thereby facilitating the subsequent extension of the information mapping head 2.

[0039] like Figures 3 to 6 As shown, the upper end face of the protective seat 1 is provided with a limiting groove adapted to the baffle plate 3, and the interior of the protective seat 1 is provided with a limiting bracket 10 adapted to the tooth plate 8, and the side wall of the tooth plate 8 is slidably set at the end of the limiting bracket 10; during operation, due to the design of the limiting groove adapted to the baffle plate 3, the baffle plate 3 can be conveniently moved on the upper end face of the protective seat 1, that is, it is conducive to the opening of the protective seat 1 being opened; the design of the limiting bracket 10 can facilitate the movement of the tooth plate 8, which is conducive to the engagement of the tooth plate 8 with the driven gear 5, and drive the driven gear 5 to rotate.

[0040] The bottom of the protective seat 1 is equipped with multiple groups of cross bars 11, and the outer circumference of each group of cross bars 11 is rotatably provided with a support 12. The telescopic end of the reciprocating cylinder 4 is provided with a linkage unit, which is used to drive the support 12 to rotate and fix. When working, when the telescopic end of the reciprocating cylinder 4 drives the information mapping head 2 to move upward, the reciprocating cylinder 4 will simultaneously drive the support 12 to rotate through the linkage unit, so that each support 12 is opened and attached. Figure 8 As shown in the figure, this ensures the stability of the geographic information surveying and mapping equipment during use.

[0041] like Figures 3 to 9 As shown, the linkage unit includes a transverse bracket 13, which is installed at the telescopic end of the reciprocating cylinder 4. The transverse bracket 13 is installed with a pressure column 14 at the telescopic end away from the reciprocating cylinder 4. The pressure column 14 is located between two sets of brackets 12. When working, refer to the attached Figure 8 and Figure 9 As shown, since the pressure column 14 is located between two groups of supports 12, when the telescopic end of the reciprocating cylinder 4 moves upward, it will simultaneously drive the transverse support 13 to move upward, and the transverse support 13 will drive the pressure column 14 to move upward. The two ends of the pressure column 14 will move between the supports 12 and squeeze the supports 12, so that the corresponding two groups of supports 12 are opened. With this design, there is no need for staff to manually open the supports 12, and it is also convenient to store the supports 12 when not in use, and the operation is relatively convenient.

[0042] Elastic frames 15 are installed at both ends of the pressure column 14, and a limit head 16 is provided at the end of the elastic frame 15. A limit groove adapted to the limit head 16 is opened on the side wall of the support frame 12, and a circular groove 17 is opened on the side wall of the support frame 12. The shape of the circular groove 17 is adapted to the shape of the limit head 16;

[0043] During operation, when the two ends of the pressure column 14 move between the support frame 12, since the side walls of the support frame 12 are provided with limit grooves that are compatible with the limit heads 16, the movement of the limit heads 16 at the ends of the pressure column 14 can be facilitated under the limitation of the limit grooves. When the information mapping head 2 above passes through the appropriate position of the protective seat 1, the limit heads 16 also move to the inside of the circular groove 17. In this way, under the elastic force of the elastic frame 15, the limit heads 16 can be tightly stuck in the inside of the circular groove 17, ensuring the stability of the support frame 12 when it is opened, and the operation is more convenient.

[0044] A gripping plate 18 is installed at the bottom of the support frame 12, and a plurality of rubber gripping rods are provided at the bottom of the gripping plate 18. The surfaces of the limit head 16 and the circular groove 17 are both provided with rounded corners. When working, the gripping plate 18 is provided. After the position of the support frame 12 is adjusted, the gripping plate 18 can improve the stability of the surveying and mapping equipment and make operation more convenient.

[0045] The telescopic end of the reciprocating cylinder 4 is equipped with an electric push rod 19, and the telescopic end of the electric push rod 19 is connected to the surveying and mapping platform 201 inside the information surveying and mapping head 2; during operation, when the information surveying and mapping head 2 passes through the interior of the protective seat 1, if the position of the information surveying and mapping head 2 is low, the surveying and mapping platform 201 inside it can be driven to move by controlling the electric push rod 19, so that the surveying and mapping platform 201 moves up. Similarly, if the position of the information surveying and mapping head 2 is high, the surveying and mapping platform 201 inside it can be driven to move by controlling the electric push rod 19, so that the surveying and mapping platform 201 moves down, which is convenient for the staff to use.

[0046] When working, in the initial state, that is, when the information mapping head 2 is not in use, the information mapping head 2 is located inside the protective seat 1, and the two sets of shielding plates 3 close the opening above the protective seat 1. Figure 1 and Figure 2 When the geographic information mapping device needs to be used, the telescopic end of the reciprocating cylinder 4 drives the information mapping head 2 to move upward, and the two sets of shielding plates 3 will slide above the protective seat 1, so that the opening of the protective seat 1 is opened, and then the information mapping head 2 will move to the adjacent Figure 4 As shown in the position, the staff can realize geographic information mapping and processing through the information mapping head 2. Such a design can protect the information mapping head 2 when not in use, solving the problem in the prior art that the information mapping head 2 is exposed to the outside and may be damaged by objects;

[0047] When the telescopic end of the reciprocating cylinder 4 drives the information mapping head 2 to move upward, the telescopic end of the reciprocating cylinder 4 will drive the driven gear 5 to rotate through the driving unit, and the driven gear 5 will drive the eccentric shaft 501 on its outer surface to rotate, and the eccentric shaft 501 will drive the shielding plate 3 to move through the hinged connecting bracket 6, so that the shielding plates 3 on both sides will move away from each other. Figure 4 After the position is shown, the operation of the reciprocating cylinder 4 is stopped, and the use of the information mapping equipment can be realized. There is no need for the staff to manually remove it, and the operation is relatively convenient. When the telescopic end of the reciprocating cylinder 4 drives the information mapping head 2 to move upward, it will simultaneously drive the fixed bracket 7 to move upward, and the fixed bracket 7 drives the gear plate 8 to move upward. The gear plate 8 will drive the driven gear 5 meshed with it to rotate, and the driven gear 5 will drive the shielding plate 3 to move through the above-mentioned connecting bracket 6, so that the shielding plate 3 automatically opens.

[0048] Due to the design of the limiting groove adapted to the shielding plate 3, the shielding plate 3 can be easily moved on the upper end surface of the protective seat 1, which is conducive to the opening of the protective seat 1 being opened; the design of the limiting bracket 10 can facilitate the movement of the tooth plate 8, which is conducive to the engagement of the tooth plate 8 with the driven gear 5 and drives the driven gear 5 to rotate; when the telescopic end of the reciprocating cylinder 4 drives the information mapping head 2 to move upward, the reciprocating cylinder 4 will simultaneously drive the support frame 12 to rotate through the linkage unit, so that each support frame 12 is opened and presented to the attached position. Figure 8 The position shown in the figure can ensure the stability of the geographic information surveying and mapping equipment during use; refer to the attached Figure 8 and Figure 9 As shown, since the pressure column 14 is located between the two groups of support frames 12, when the telescopic end of the reciprocating cylinder 4 moves upward, it will simultaneously drive the transverse support 13 to move upward, and the transverse support 13 will drive the pressure column 14 to move upward. The two ends of the pressure column 14 will move between the support frames 12 and squeeze the support frames 12, so that the corresponding two groups of support frames 12 are opened. This design eliminates the need for manual opening of the support frames 12 by staff, and also facilitates the storage of the support frames 12 when not in use, making operation more convenient.

[0049] When the two ends of the pressure column 14 move between the support frame 12, since the side wall of the support frame 12 is provided with a limit groove adapted to the limit head 16, under the limit of the limit groove, the movement of the limit head 16 at the end of the pressure column 14 can be facilitated. When the upper information mapping head 2 passes through the appropriate position of the protective seat 1, the limit head 16 also moves to the inside of the circular groove 17. In this way, under the elastic force of the elastic frame 15, the limit head 16 can be tightly stuck in the inside of the circular groove 17, ensuring the stability of the support frame 12 when it is opened, and the operation is more convenient; a gripping floor 1 is provided. 8. After the position of the support frame 12 is adjusted, the stability of the surveying and mapping equipment can be improved under the action of the gripping floor 18, and the operation is more convenient; when the information surveying and mapping head 2 passes through the interior of the protective seat 1, if the position of the information surveying and mapping head 2 is low, the surveying and mapping platform 201 inside it can be driven to move by controlling the electric push rod 19, so that the surveying and mapping platform 201 moves up. Similarly, if the position of the information surveying and mapping head 2 is high, the surveying and mapping platform 201 inside it can be driven to move by controlling the electric push rod 19, so that the surveying and mapping platform 201 moves down, which is convenient for the use of the staff.
