Description

Technical Field

[0001] The present invention relates to the technical field of urban planning surveying and mapping, and particularly to a mobile surveying device for urban planning surveying and mapping. Background Art

[0002] Urban planning surveying and mapping is an indispensable part of the urban planning process. It mainly obtains spatial information on aspects such as the current situation of the city, land use, transportation, environment, buildings, etc. through precise measurement and data collection, providing a scientific basis for the formulation and implementation of urban planning, ensuring that all planning decisions are based on accurate, timely, and detailed geospatial data. When conducting urban planning surveying and mapping, mobile surveying equipment is required, such as panoramic cameras, integrated lidar, road scanners, inertial measurement units, photogrammetry equipment, etc. By installing a variety of surveying equipment on a mobile platform with good mobility (such as a car, driverless vehicle, or drone), the mobile platform drives the surveying equipment to perform rapid and large-scale surveying work in the urban environment, achieving efficient and flexible data collection. The surveying equipment is usually connected to the vehicle using a bracket on the roof to ensure stable and efficient data collection during operation.

[0003] The data collected by the surveying equipment is often stored in the local memory of the equipment. These devices usually do not have wireless data transmission capabilities or have a low transmission speed. Therefore, after the collection is completed, the equipment needs to be removed from the vehicle body and connected to a computer to directly read and process the collected data.

[0004] Currently, the common installation method of surveying equipment usually uses bolts and nuts to connect it to the roof bracket. Although reliable, the installation and disassembly time is long. It is necessary to install multiple bolt and nut connection points one by one, and the operation is rather cumbersome, which is not convenient for removing the surveying equipment to read data. At the same time, when replacing the surveying equipment or using multiple different functional types of surveying equipment, it is necessary to readjust each connection point, affecting the rapid deployment and use of the surveying equipment, and lacking flexibility. Summary of the Invention

[0005] The present invention provides a mobile surveying device for urban planning surveying and mapping, which solves the technical problems that the current surveying equipment often uses the bolt and nut connection method to fix it on the roof bracket. Although this method is reliable, the installation and disassembly are cumbersome, and it is necessary to install multiple bolts one by one, which takes a long time and affects the rapid removal of the equipment and data reading. At the same time, when replacing the surveying equipment or using different functional modules, it is necessary to readjust each connection point, resulting in inflexible and inefficient equipment deployment.

[0006] A mobile measurement device for urban planning surveying and mapping provided by the present invention includes two strip-shaped mounting seats symmetrically distributed front and back, a connecting plate fixedly connected between the two strip-shaped mounting seats, and a strip-shaped plate slidably connected to the upper end surface of the strip-shaped mounting seat through a connecting telescopic rod. Fixed clamping tongue plates are fixedly connected to the upper parts on the left and right sides of the strip-shaped mounting seats. Inverted T-shaped mounting grooves are formed in the strip-shaped mounting seats. Two moving clamping tongue plates for cooperating with the fixed clamping tongue plates are symmetrically slidably connected in the horizontal section of the T-shaped mounting groove. A top-moving mechanism is jointly arranged between the T-shaped mounting groove and the strip-shaped plate to push the two moving clamping tongue plates located on the left and right to move towards each other so as to be quickly mounted on the surveying vehicle in cooperation with the fixed clamping tongue plates. A locking mechanism is jointly arranged between the strip-shaped plate and the strip-shaped mounting seat to lock and limit the top-moving mechanism after operation. An adjustable bearing part for quickly mounting different measurement modules and flexibly adjusting positions according to the requirements of different measurement modules is jointly arranged on the upper end surfaces of the two strip-shaped plates.

[0007] In a possible implementation manner, the top-moving mechanism includes two sliding plates symmetrically slidably connected in the horizontal section of the T-shaped mounting groove. Connecting rods are hinged to the opposite sides of the two sliding plates. An articulated seat is jointly hinged to the upper ends of the two connecting rods. A pillar is fixedly connected to the upper end surface of the articulated seat. The strip-shaped plate is fixedly connected to the upper part of the pillar. The moving clamping tongue plates are fixedly connected to the opposite sides of the two sliding plates on the left and right.

[0008] In a possible implementation manner, a first top spring is fixedly connected to the lower end surface of the articulated seat. A top block is fixedly connected to the lower end of the first top spring. An embedding groove for the first top spring and the top block to extend into is formed at the bottom of the T-shaped mounting groove and directly below the top block.

[0009] In a possible implementation manner, the locking mechanism includes two slots symmetrically formed in the upper end surface of the strip-shaped mounting seat and two inserting tongues symmetrically fixedly connected to the lower end surface of the strip-shaped plate for cooperating with the slots. Card grooves are formed on the opposite sides of the two inserting tongues. Sliding grooves are formed on the groove walls on the mutually remote sides of the two slots. A control moving component is slidably arranged between the sliding grooves and the slots. A clamping column for cooperating with the card groove is arranged on the control moving component. The control moving component is used to control the separation of the clamping column from the card groove.

[0010] In a possible implementation manner, the control moving component includes a slider slidably connected in the sliding groove. A second top spring is fixedly connected between the slider and the sliding groove. A strip-shaped through groove is jointly formed on the sides of the sliding groove and the slot close to the connecting plate. A columnar groove is formed on the side of the slider close to the connecting plate. A sliding rod is slidably connected in the columnar groove. A limiting spring is fixedly connected between the sliding rod and the columnar groove. A strip-shaped plate is fixedly connected to the outside of the sliding rod. The clamping column is fixedly connected to the end surface of the strip-shaped plate close to the slider.

[0011] In a possible implementation, open-ended positioning grooves are formed on the opposite sides of the left and right movable tongue plates. The open-ended positioning grooves are composed of semi-circular grooves and trapezoidal grooves communicating with the semi-circular grooves.

[0012] In a possible implementation, cables are fixedly connected together at the proximal ends of two diagonal sliders. The intersection of the two cables is fixedly connected to each other through a connecting block.

[0013] In a possible implementation, the adjustable bearing part includes a rectangular frame fixedly connected to the upper end faces of two strip-shaped plates. Two guide rails are symmetrically fixedly connected to the upper end face of the rectangular frame through support blocks. A plurality of sliding sleeves are slidably connected to the outside of the guide rails at equal intervals. The upper end faces of the sliding sleeves are fixedly connected with rectangular seats with upper openings. A rectangular groove is formed in the inner cavity of the rectangular seat. A first abutting plate is slidably connected to the left and right sides of the rectangular groove symmetrically. The lower end face of the rectangular seat is slidably connected to vertical plates symmetrically through return springs. A sliding column that slidably penetrates through the rectangular seat is fixedly connected to the side of the vertical plate close to the rectangular seat. The side of the sliding column away from the vertical plate extends into the rectangular groove and is fixedly connected to the first abutting plate. A pull ring is fixedly connected to the side of the vertical plate away from the rectangular seat.

[0014] In a possible implementation, positioning holes are formed at equal intervals on the left and right sides of the guide rails. Through holes are formed in the left and right wall plates of the sliding sleeves. An L-shaped plate is fixedly connected to the side of the vertical plate close to the rectangular seat. A positioning column for cooperating with the through holes and the positioning holes is fixedly connected to the side of the vertical section of the L-shaped plate close to the sliding sleeve.

[0015] In a possible implementation, second abutting plates are slidably connected to the front and rear groove walls of the rectangular groove through spring telescopic columns. Two wedge-shaped blocks for cooperating with the second abutting plates are symmetrically fixedly connected to the side of the first abutting plate close to the second abutting plate. The inclined surfaces of the wedge-shaped blocks abut against the second abutting plates.

[0016] From the above technical solutions, it can be seen that the present invention has the following advantages:

[0017] In the present invention, after the strip-shaped plate is pressed to trigger the top displacement mechanism, the tongue plate can quickly extend and cooperate with the fixed tongue plate, so as to firmly connect the measuring device to the roof bracket. There is no need to install multiple bolts and nuts one by one. The installation operation only requires a simple pressing action. When disassembling, only need to easily operate the locking mechanism to make the top displacement mechanism run in the reverse direction, and the tongue plate can quickly retract, and the connection point with the roof bracket can be quickly released, greatly reducing the operation steps, realizing the flexible installation and disassembly of the present invention and the roof bracket, and improving the installation speed.

[0018] In the present invention, the combination of the first pressing plate, the second pressing plate, the vertical plate, the positioning holes, the through holes and the positioning columns in the adjustable bearing part realizes the rapid installation of multiple measurement modules with different functions into the rectangular seat, can flexibly install and disassemble measurement modules with different functions, meet the requirements of different measurement tasks, enhance the versatility, and clamp and limit the measurement module from multiple directions. At the same time, the position of the rectangular seat can be locked, which can flexibly adapt to different measurement scenarios and improve the overall adaptability of the device.

[0033] See also Figure 7 and Figure 8, in this embodiment, the adjustable bearing part 8 includes a rectangular frame 81 fixedly connected to the upper end faces of two strip-shaped plates 2 together. On the upper end face of the rectangular frame 81, two guide rails 82 are fixedly connected symmetrically left and right through support blocks. A number of sliding sleeves 83 are slidably connected to the outside of the guide rails 82 at equal intervals. The upper end face of the sliding sleeve 83 is fixedly connected with a rectangular seat 84 with an upper opening. A rectangular groove 85 is opened in the inner cavity of the rectangular seat 84. A first pressing plate 86 is slidably connected symmetrically left and right in the rectangular groove 85. The lower end face of the rectangular seat 84 is slidably connected symmetrically left and right through a return spring with a vertical plate 87. A sliding column 88 that slidably penetrates through the rectangular seat 84 is fixedly connected to the side of the vertical plate 87 close to the rectangular seat 84. The side of the sliding column 88 away from the vertical plate 87 extends into the rectangular groove 85 and is fixedly connected to the first pressing plate 86. A pull ring is fixedly connected to the side of the vertical plate 87 away from the rectangular seat 84.

[0034] Please refer to Figure 8 and Figure 9 , positioning holes 89 are equally spaced on the left and right sides of the guide rail 82. Through holes 810 are opened on the left and right wall plates of the sliding sleeve 83. An L-shaped plate is fixedly connected to the side of the vertical plate 87 close to the rectangular seat 84. A positioning column 811 for cooperating with the through hole 810 and the positioning hole 89 is fixedly connected to the side of the vertical section of the L-shaped plate close to the sliding sleeve 83. Second pressing plates 812 are slidably connected to the front and rear groove walls of the rectangular groove 85 through spring telescopic columns. Two wedge-shaped blocks 813 for cooperating with the second pressing plates 812 are fixedly connected symmetrically front and back to the side of the first pressing plate 86 close to the second pressing plates 812. The inclined surfaces of the wedge-shaped blocks 813 are in contact with the second pressing plates 812.

[0035] Select the measuring equipment to be used. Then select a rectangular seat 84 to install the measuring equipment. Then pull the pull rings on both sides of the rectangular seat 84 to move away from each other. The pull rings then drive the first pressing plate 86 to move and retract into the rectangular groove 85 through the sliding column 88. The first pressing plate 86 will also drive the wedge-shaped block 813 to move at the same time. The spring telescopic column pulls the second pressing plate 812 to retract into the rectangular groove 85. Then move the rectangular seat 84 to drive the sliding sleeve 83 to move on the guide rail 82, so that the rectangular seat 84 moves to the best position required by the measuring equipment. Then place the measuring equipment into the rectangular seat 84. Then release the pull rings. The return spring pulls the vertical plate 87 to move closer to the rectangular seat 84. The vertical plate 87 then drives the first pressing plate 86 to move through the sliding column 88. The first pressing plate 86 drives the wedge-shaped block 813 to move again. During the process of the two wedge-shaped blocks 813 on the left and right moving closer to each other, their inclined surfaces squeeze both sides of the second pressing plate 812, so that the two second pressing plates 812 on the front and back move closer to each other. The first pressing plate 86 and the second pressing plate 812 move towards the inside of the rectangular seat 84 at the same time until both the first pressing plate 86 and the second pressing plate 812 are in contact with the measuring equipment, and the measuring equipment can be quickly installed into the rectangular seat 84; repeat the above steps to install the remaining measuring equipment responsible for different measuring functions into the remaining rectangular seats 84.

[0036] The vertical plate 87 moves closer to the rectangular seat 84, and at the same time, it will drive the L-shaped plate to move synchronously. Then the L-shaped plate drives the positioning column 811 to move, so that the positioning column 811 is inserted into the overlapping through holes 810 and positioning holes 89, thereby locking and limiting the rectangular seat 84 after the position is adjusted.

[0037] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In this embodiment, the top-moving mechanism 6 includes two sliding plates 61 that are symmetrically and slidably connected to the horizontal section of the T-shaped installation groove 4 on the left and right. Connecting rods 62 are hinged to the opposite sides of the two sliding plates 61. The upper ends of the two connecting rods 62 are jointly hinged to a hinge seat 63. A support column 64 is fixedly connected to the upper end surface of the hinge seat 63. The strip-shaped plate 2 is fixedly connected to the upper part of the support column 64. The movable tongue plate 5 is fixedly connected to the opposite sides of the two sliding plates 61 on the left and right. A first top spring 9 is fixedly connected to the lower end surface of the hinge seat 63. A top block is fixedly connected to one end of the first top spring 9. An embedding groove for the top spring and the top block to extend into is opened at the bottom of the T-shaped installation groove 4 and directly below the top block. Open-shaped positioning grooves 10 are opened on the opposite sides of the two movable tongue plates 5. The open-shaped positioning groove 10 is composed of a semi-circular groove and a trapezoidal groove communicating with the semi-circular groove.

[0038] Please refer to Figure 1 、 Figure 5 and Figure 6 In this embodiment, the locking mechanism 7 includes two slots 71 that are symmetrically opened on the upper end surface of the strip-shaped mounting seat 1 and two tongues 72 that are symmetrically and fixedly connected to the lower end surface of the strip-shaped plate 2 for cooperating with the slots 71. The vertical cross-section of the tongue 72 is in the shape of a right trapezoid. Card slots 73 are opened on the opposite sides of the two tongues 72. Slide grooves 74 are opened on the mutually remote side walls of the two slots 71. A control and movement component 75 is slidably arranged between the slide groove 74 and the slot 71. A clamping column 76 that cooperates with the card slot 73 is arranged on the control and movement component 75. The control and movement component 75 is used to control the separation of the clamping column 76 from the card slot 73. The control and movement component 75 includes a slider 751 that is slidably connected to the slide groove 74. A second top spring is fixedly connected between the slider 751 and the slide groove 74. A strip-shaped through groove 752 is jointly opened on the side of the slide groove 74 and the slot 71 close to the connecting plate. A columnar groove is opened on the side of the slider 751 close to the connecting plate. A sliding rod 753 is slidably connected in the columnar groove. A limiting spring is fixedly connected between the sliding rod 753 and the columnar groove. A strip-shaped plate 754 is fixedly connected to the outside of the sliding rod 753. The clamping column 76 is fixedly connected to the end surface of the strip-shaped plate 754 close to the slider 751. The adjacent ends of the two sliding rods 753 distributed diagonally are jointly fixedly connected to a cable 11. The intersection of the two cables 11 is fixedly connected to each other through a connecting block.

[0039] After installing measurement devices responsible for different measurement functions on the adjustable carrier part 8, a large integrated measurement device capable of simultaneously measuring multiple different aspects is formed. Lift the strip-shaped mounting base 1 and move it to the bracket on the top of the vehicle, so that the fixed tongue plate 3 rests on the upper part of the roof bracket. Then, manually press down the rectangular frame 81. The rectangular frame 81 then presses down on the strip-shaped plate 2. The strip-shaped plate 2 drives the hinge seat 63 to move downward. The hinge seat 63 then pushes the connecting rod 62 to move downward, causing the lower ends of the left and right connecting rods 62 to move away from each other. The connecting rod 62 then pushes the movable tongue plate 5 to move synchronously through the sliding plate 61. The movable tongue plate 5 gradually extends out of the T-shaped mounting groove 4 until the movable tongue plate 5 moves into the lower side of the horizontal rod section in the roof bracket. At the same time, the movable tongue plate 5 drives the open-shaped positioning groove 10 to abut against the outside of the vertical rod section in the roof bracket, realizing the connection and installation of the strip-shaped mounting base 1 and the roof bracket. At this time, the connecting rod 62 is in a horizontal state. The hinge seat 63 drives the first top spring 9 to extend into the embedding groove. The first top spring 9 then drives the top block to abut against the bottom of the embedding groove cavity. The first top spring 9 will gradually contract in the embedding groove due to the continuous downward movement of the hinge seat 63 until it is completely contracted.

[0040] During the process of the movable tongue plate 5 extending out of the strip-shaped mounting base 1, the strip-shaped plate 2 moves downward to drive the insertion tongue 72 to start inserting into the insertion slot 71. The inclined surface of the insertion tongue 72 abuts against the outer wall of the clamping column 76 and pushes the clamping column 76 to move towards the direction close to the sliding groove 74 until the clamping column 76 is pushed and moved to the side position of the clamping column 76. When the insertion tongue 72 is completely inserted into the insertion slot 71, the clamping groove 73 moves to a position flush with the clamping column 76. Then, the second top spring pushes the slider 751 to move. The slider 751 then drives the clamping column 76 to move away from the sliding groove 74 through the sliding rod 753 and the strip-shaped plate 754, causing the clamping column 76 to slide into the clamping groove 73 to clamp the insertion tongue 72, thereby locking and limiting the downward-moved strip-shaped plate 2, and indirectly making the extended movable tongue plate 5 in a locked state.

[0041] When the measurement finishes collecting data, just manually pull the cable 11 to drive the sliding rod 753 to move. The sliding rod 753 then drives the clamping column 76 to move through the strip-shaped plate 754. The strip-shaped plate 754 drives the clamping column 76 to move into the strip-shaped through groove 752. After the clamping column 76 completely slides into the strip-shaped through groove 752, it will move out of the clamping groove 73. Then, the first top spring 9 resets and extends to push the hinge seat 63 to move upward. The hinge seat 63 then pushes the strip-shaped plate 2 to move upward through the support column 64. The strip-shaped plate 2 then drives the insertion tongue 72 to move out of the insertion slot 71. The upward movement of the hinge seat 63 drives the movable tongue plate 5 to gradually retract into the T-shaped mounting groove 4 through the connecting rod 62 and the sliding plate 61. Then, the strip-shaped mounting base 1 can be lifted upward and removed from the roof of the vehicle, facilitating the removal and reading of the measurement device after collecting data, and at the same time facilitating the quick installation of the next measurement device.

[0042] During operation, first install the measuring devices for measuring different aspects into the adjustable bearing part 8. Then, lift the strip-shaped mounting base 1 and place it on the roof rack. Next, press down the strip-shaped plate 2, and the strip-shaped plate 2 then triggers the operation of the top displacement mechanism 6. The top displacement mechanism 6 pushes the moving tongue plate 5 to gradually extend from the strip-shaped mounting base 1. Through the cooperation of the fixed tongue plate 3 and the extended moving tongue plate 5, they are pressed against the upper and lower sides of the roof rack respectively, and then the overall measuring device can be quickly installed on the roof rack. Then, use the locking mechanism 7 to indirectly limit the extended moving tongue plate 5. After collecting the data, pull the cable 11 to trigger the operation of the locking mechanism 7 to release the limit on the moving tongue plate 5. Then, the top displacement mechanism 6 moves in the reverse direction to drive the moving tongue plate 5 to retract into the strip-shaped mounting base 1, and the strip-shaped mounting base 1 can be quickly removed from the roof rack.
