Description

Technical Field

[0001] The invention belongs to the technical field of exploration equipment, and in particular relates to an outdoor survey device for urban and rural planning. Background Art

[0002] Land surveying is the process of conducting on-site surveys and measurements before construction to determine the area of ​​the land. An important part of land surveying is measuring the area of ​​the land. Existing surveying methods mostly use a soft ruler or tape measure for measurement. Since the area of ​​the land under construction is large and the length of the ruler is fixed, when measuring the length of the land, it is necessary to perform multiple measurements in sections to measure the length of the land. Since the segmented measurement requires the surveyor to repeatedly determine the starting point of the measurement, large errors are easily generated during the determination process. Therefore, the measurement results will eventually have large errors, and this measurement method has low measurement efficiency. Summary of the Invention

[0003] In order to solve the above-mentioned deficiencies in the prior art, the present invention provides an outdoor survey device for urban and rural planning.

[0004] The present application proposes an outdoor survey device for urban and rural planning, comprising a fixed plate, a plurality of movable wheels movably mounted on the bottom surface of the fixed plate, a handle fixedly mounted on the front end of the top surface of the fixed plate, a support assembly fixedly mounted on the top surface of the fixed plate, a height adjustment assembly mounted on the support assembly, a roller movably mounted on the bottom end of the height adjustment assembly through an axis, the roller is located below the fixed plate, a limiting assembly is mounted behind the bottom end of the height adjustment assembly, and a plurality of slots are provided on the top surface of the fixed plate.

[0005] Specifically, the support assembly includes two vertical plates, the bottom ends of the vertical plates are fixedly connected to the top surface of the fixed plate, the two vertical plates are respectively located on both sides of the fixed plate, and the top ends of the two vertical plates are fixedly connected by a connecting plate. A through hole is opened on the top surface of the connecting plate, and a rotating shaft is installed in the bearing in the through hole, and a rotating handle is fixedly installed on the top end of the rotating shaft.

[0006] Specifically, the height adjustment assembly includes a group of through grooves opened on the top surface of the fixed plate, the through groove group includes two through grooves, and a slider is slidably installed in the through groove. The top ends of the two sliders are fixedly connected by a connecting block. A screw hole is opened on the top surface of the connecting block. The bottom end of the rotating shaft is fixedly installed with a screw rod, the screw rod passes through the screw hole, and the bottom end of the screw rod is movably connected to the top surface of the fixed plate. A roller is movably installed between the bottom ends of the two sliders through an axis.

[0007] Specifically, the limiting assembly includes an L-shaped plate, a contact plate is provided behind the vertical plate of the L-shaped plate, and the contact plate is connected to the vertical plate of the L-shaped plate via a spring.

[0008] Specifically, the contact plate is a triangular plate.

[0009] Compared with the prior art, the present invention has the following beneficial effects: Place the tripod of a measuring device (the measuring device includes a total station, longitude and latitude, and level) on the fixed plate, that is, insert the bottom end of the tripod leg into the slot. When it needs to be moved, push the handle, and the fixed plate can move under the rolling of the moving wheel, driving the measuring device above to move. Compared with the existing method of directly carrying the tripod and the measuring device above to move, it is more convenient. After moving to the measuring point, the tripod does not need to repeat the opening and contraction process, which reduces the useless time in measurement. In addition, the measuring device can be placed on the fixed plate for carrying and transportation, and can also be carried at the same time. With two or more measuring devices, the survey is more comprehensive during use; when outdoor distance measurement is required, the height adjustment component adjusts the height of the roller so that the roller contacts the ground. At this time, the limiting component also moves downward, and there is a small gap between the bottom end of the limiting component and the ground. Push the handle to control the moving wheel to rotate, and the roller also moves on the ground. During the rotation of the roller, the information is transmitted to the display panel through signal transmission to display the walking distance. The limiting component is located at the front end of the roller's forward direction. When the limiting component contacts an obstacle, a prompt is given to avoid the roller from deflecting or sliding, thereby preventing data anomalies. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0013] An outdoor survey device for urban and rural planning, such as Figure 1-2As shown, it includes a fixed plate 1, several movable wheels 2 are movably installed on the bottom surface of the fixed plate 1, a handle 3 is fixedly installed on the front end of the top of the fixed plate 1, a support assembly is fixedly installed on the top surface of the fixed plate 1, a height adjustment assembly is installed on the support assembly, and a roller 4 is movably installed on the bottom end of the height adjustment assembly through an axis. The roller 4 is located below the fixed plate 1, and a limiting assembly is installed behind the bottom end of the height adjustment assembly. Several slots 5 are opened on the top surface of the fixed plate 1.

[0014] The moving wheel 2 has a brake function, an electronic encoder is installed on the shaft, and a display panel and a battery box are installed on the support assembly. The electronic encoder converts the rotation signal into an electric pulse and transmits the information to the display panel. A tripod of a measuring device (the measuring device includes a total station, a longitude and latitude, and a level) is placed on the fixed plate 1, that is, the bottom end of the tripod leg is inserted into the slot 5. When moving, by pushing the handle 3, the fixed plate 1 can move under the rolling of the moving wheel 2, driving the measuring device above to move. Compared with the existing method of directly carrying the tripod and the measuring device above to move, it is more convenient. Moreover, after moving to the measuring point, the tripod does not need to repeat the opening and contraction process, which reduces the useless time in measurement. Moreover, the measuring device can be placed on the fixed plate 1 for carrying and transportation, and two or more measuring devices can be carried at the same time, so that the survey is more comprehensive during use; when outdoor distance measurement is required, the height adjustment component adjusts the height of the roller 4 so that the roller 4 contacts the ground. At this time, the limiting component also moves downward, and there is a small gap between the bottom end of the limiting component and the ground. Push the handle 3 to control the moving wheel 2 to rotate, and the roller 4 also moves on the ground. During the rotation process, the roller 4 transmits information to the display panel through signal transmission to display the walking distance. The limiting component is located at the front end of the forward direction of the roller 4. When the limiting component contacts an obstacle, a prompt is given to avoid the roller deflection or side slip, thereby preventing data abnormalities.

[0015] Specifically, the support assembly described in this embodiment includes two vertical plates 6, the bottom ends of the vertical plates 6 are fixedly connected to the top surface of the fixed plate 1, the two vertical plates 6 are respectively located on both sides of the fixed plate 1, and the top ends of the two vertical plates 6 are fixedly connected by a connecting plate 7. A through hole is provided on the top surface of the connecting plate 7, and a rotating shaft 8 is installed with a bearing in the through hole, and a rotating handle is fixedly installed on the top of the rotating shaft 8.

[0016] The rotation of the rotating shaft 8 can control the height adjustment component to adjust the height. The outer wall of the outer ring of the bearing is fixedly connected to the inner wall of the through hole, and the inner wall of the inner ring of the bearing is fixedly connected to the outer periphery of the rotating shaft 8. The display panel and the battery box are installed on the top surface of the connecting plate 7. Rotate the rotating shaft 8 to control the height adjustment component to adjust the height and control the roller to contact or separate from the ground.

[0017] Furthermore, the height adjustment assembly described in this embodiment includes a group of through grooves opened on the top surface of the fixed plate 1, and the through groove group includes two through grooves, in which a slider 9 is slidably installed. The top ends of the two sliders 9 are fixedly connected by a connecting block 10. A screw hole is opened on the top surface of the connecting block 10, and a screw rod 11 is fixedly installed at the bottom end of the rotating shaft 8. The screw rod 11 passes through the screw hole, and the bottom end of the screw rod 11 is movably connected to the top surface of the fixed plate. The roller 4 is movably installed between the bottom ends of the two sliders 9 through the axis.

[0018] A measuring starting point arrow is installed on the shaft. The rotation of the rotating shaft 8 drives the screw 11 to rotate. The screw 11 cooperates with the screw hole thread to control the connecting block 10 and the slider 9 to move downward, so that the roller 4 contacts the ground. Moreover, the self-locking property of the screw and the screw hole can prevent the slider 9 from sliding up and down, making it more stable during use. Moreover, the height change of the roller 4 can be adjusted more finely through the thread cooperation of the screw 11 and the screw hole.

[0019] Furthermore, the limiting assembly described in this embodiment includes an L-shaped plate 12, and a contact plate 13 is provided behind the vertical plate of the L-shaped plate 12. The contact plate 13 is connected to the vertical plate of the L-shaped plate 12 through a spring.

[0020] The spring is installed with a pressure sensor, which transmits the detected information to the processor, and the processor transmits the information to the display screen installed on the top surface of the connecting plate 7. The contact plate 13 first contacts the obstacle in the forward direction. When the obstacle cannot be pushed away by the contact plate 13, the contact plate 13 moves toward the L-shaped plate 12 under the pressure of the obstacle. The spring is compressed and the pressure sensor detects the pressure change. When the threshold is reached, the fixed plate 1 stops moving and the obstacle under the fixed plate is cleared to avoid the obstacle affecting the measurement.

[0021] Furthermore, the contact plate 13 described in this embodiment is a triangular plate. The tip of the triangular contact plate 13 faces the forward direction of the roller. The tip can push the obstacle to the side of the contact plate 13, so that the obstacle moves out of the forward path of the roller.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
