Description

Technical Field

[0001] The utility model relates to the technical field of surveying and mapping, in particular to a fixed-point device for surveying and mapping. Background Technique

[0002] Surveying and mapping literally means measurement and mapping. Based on computer technology, optoelectronic technology, network communication technology, space science, and information science, with the global navigation satellite positioning system (GNSS), remote sensing (RS), and geographic information system (GIS) as the technical cores, it selects existing feature points and boundaries on the ground and obtains graphical and position information reflecting the ground status through measurement means for use in engineering construction, planning and design, and administrative management.

[0003] Before the construction project starts, surveying and mapping are required. When conducting surveying and mapping, first, a reference point needs to be found, and then surveying and mapping are carried out around the reference point. When conducting surveying and mapping, it is necessary to mark the reference point to avoid inaccurate surveying and mapping caused by the offset of the reference point.

[0004] According to the search, the Chinese patent document, publication number: CN218496109U, discloses a fixed-point marking device for surveying and mapping. Through the mutual cooperation between the fixed frame, the marking rod, and the first fixing plate, the function of marking the reference point can be realized. Through the mutual cooperation between the fixed frame, the fixed block, the insertion rod, the second fixing plate, the limiting rod, the telescopic spring, the pulling plate, the sliding rod, the limiting hole, the hinged column, and the clamping strip, the function of fixing the device can be realized, and it can effectively avoid the offset of the reference point caused by the movement of the device. However, in the actual operation process, since some surveying and mapping locations are carried out on existing buildings, the surveying and mapping ground may be cement, so it is very difficult to pierce the fixed-point support rod of the mark into the ground by pressing. For this reason, we propose a fixed-point device for surveying and mapping to solve the above problems. Content of the Utility Model

The two ends of the linkage rod 705 are respectively hinged to the slider 2 and the movable rod 702. Specifically, a handle is installed on one side of the movable rod 702. The tester can drive the movable rod 702 to rotate on the first support rod 701 through the handle, and thus drive the slider 2 to slide outside the guide block 704 through the hinged linkage rod 705. The cross section of the guide block 704 is a trapezoidal structure.

[0031] When the present utility model is specifically implemented, as Figure 1 and Figure 4 shown. A reset device 8 is installed under the slider 2. The reset device 8 includes a conduit 801 fixedly connected to the base 1. A reset spring 802 is installed in the conduit 801. A guide rod 803 is installed at the lower end of the slider 2 and the guide rod 803 is located in the conduit 801. When the slider 2 slides downward, it drives the guide rod 803 to move in the conduit 801 and compresses the reset spring 802.

[0032] When the present utility model is specifically implemented, as Figure 1 - and Figure 3As shown in the figure, a limit block 601 is installed on the fixed-point support rod 6. A groove 501 for the fixed-point support rod 6 and the limit block 601 to enter is formed on the fixed block 5. A moving cavity 502 is formed in the fixed block 5, and the moving cavity 502 communicates with the groove 501. An adjusting spring 503 is installed on the bottom wall of the moving cavity 502. The upper end of the adjusting spring 503 is installed with a push plate 504. A pull rod 505 is installed at the lower end of the push plate 504 and inside the adjusting spring 503, and the pull rod 505 penetrates through the fixed block 5. A moving hole for the pull rod 505 to move is formed on the fixed block 5. An installation groove 506 for the fixed-point support rod 6 to use is formed on one side of the push plate 504. Pull the pull rod 505, the adjusting spring 503 is compressed, driving the push plate 504 to move downward. The fixed-point support rod 6 and the limit block 601 enter from the groove 501. The limit block 601 is located above the push plate 504, and the fixed-point support rod 6 enters the installation groove 506. Release the pull rod 505, the adjusting spring 503 expands, driving the push plate 504 to push the limit block 601 upward for limiting. The motor 4 drives the fixed-point support rod 6 to rotate, and the fixed-point support rod 6 can be installed on the ground.

[0033] A positioning groove 101 for the fixed-point support rod 6 to use is formed on the base 1. A soil nail hole 102 is formed on the base 1. Specifically, when in use, the base 1 can be fixedly connected to the ground by installing a soil nail in the nail hole 102, or a tester stands on the base 1 and applies weight to the base 1 to limit the position of the base 1. Universal wheels are installed at the lower end of the base 1, which can drive the base 1 to move to a suitable position.

[0034] The working principle of the present utility model:

[0035] The tester moves the device to a suitable position, inserts the fixed-point support rod 6 and the limit block 601 into the groove 501. The limit block 601 is located above the push plate 504, and the fixed-point support rod 6 enters the installation groove 506. Release the pull rod 505, the adjusting spring 503 expands, driving the push plate 504 to push the limit block 601 upward for limiting. The tester can drive the movable rod 702 to rotate on the first support rod 701 through the handle, and then drive the slider 2 to slide outside the guide block 704 through the articulated linkage rod 705. The guide rod 803 moves in the conduit 801, compressing the return spring 802, thereby driving the motor 4 to move downward. The motor 4 drives the fixed-point support rod 6 to rotate, and the fixed-point support rod 6 can be installed on the ground. After installation, the motor 4 stops working. The handle is loosened, and due to the expansion of the return spring 802, the motor 4 and the fixed block 5 move upward, which can push the base 1, causing the fixed block 5 to move away from the fixed-point support rod 6 through the groove 501, so that the fixed-point support rod 6 is fixed on the ground, completing the fixed-point marking.
