Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of engineering surveying and mapping, in particular to a benchmark fixing device for engineering surveying and mapping. Background Art
[0002] Engineering surveying and mapping is an indispensable part of the engineering construction process. Through surveying and mapping, terrain, landforms and other related data can be obtained, providing a reliable basis for scientific decision-making and engineering implementation. In the surveying and mapping process, surveying poles are a common tool that are widely used to measure and mark specific points on the ground. In order to ensure the accuracy and stability of surveying and mapping work, it is usually necessary to firmly fix the surveying poles on the ground to prevent them from moving or tilting during the measurement process.
[0003] At present, common mapping pole fixing devices are mainly used for fixing on flat ground. These devices fix the pole on the ground through various mechanical structures to ensure its vertical state. However, when mapping in complex terrain such as ramps and slopes, existing pole fixing devices have certain limitations. When these devices are used on ramps, the pole will be tilted. The tilt of the pole not only affects the accuracy of the mapping data, but also increases the difficulty of observation for staff and reduces work efficiency.
[0004] The disclosure of the above background technology content is only used to assist in understanding the concept and technical solution of the utility model. It does not necessarily belong to the prior art of this patent application. In the absence of clear evidence that the above content has been disclosed on the filing date of this patent application, the above background technology should not be used to evaluate the novelty and creativity of the present application. Utility Model Content
[0005] The present application provides a benchmark fixing device for engineering surveying and mapping, which is used to solve the problem that when the existing fixing device fixes the benchmark on a ramp, the benchmark will be in an inclined state, affecting the accuracy of surveying and mapping data, increasing the difficulty of observation for staff, and reducing work efficiency.
[0006] In order to achieve the above objectives, this application adopts the following technical solutions:
[0007] A benchmark fixing device for engineering surveying and mapping comprises a base, a plurality of ground piles, a rotating seat, a mounting seat, an adjusting rod, an adjusting disk, and a locking piece, wherein a plurality of fixing holes are opened on the base; the plurality of ground piles are arranged in one-to-one correspondence with the plurality of fixing holes, and a corresponding ground pile is inserted into each fixing hole; the rotating seat is arranged on the base; the mounting seat is used for detachably fixing and connecting the benchmark; the mounting seat is rotatably connected to the rotating seat; one end of the adjusting rod is fixedly connected to the mounting seat; the adjusting disk is arranged on the base, and an arc groove is arranged on the adjusting disk; the other end of the adjusting rod is penetrated through the arc groove, and the other end of the adjusting rod can slide along the extension direction of the arc groove; the locking piece is used to fix the position of the adjusting rod in the arc groove.
[0008] In the embodiment of the present application, when in use, the base is placed at the surveying and mapping site, and multiple ground stakes are inserted into the multiple fixing holes on the base to stabilize the base on the ground. The benchmark is fixedly mounted on the mounting seat, and by toggling the benchmark, the adjustment rod can slide along the arc groove to adjust the inclination angle of the benchmark. When the benchmark is adjusted to a vertical state, the position of the adjustment rod is locked by the locking member to fix the angle of the benchmark, thereby ensuring the stability of the benchmark during the surveying and mapping process. In this way, the benchmark can be firmly fixed on uneven terrain (such as ramps, slopes, etc.) to prevent the benchmark from tilting, thereby ensuring the accuracy of the surveying and mapping data and the work efficiency of the staff, and reducing the difficulty of observation for the staff.
[0009] In some possible implementations, the locking member is a locking sleeve, the circumferential inner surface of the locking sleeve is provided with an internal thread, the end of the adjusting rod away from the mounting seat is provided with an external thread, the internal thread and the external thread cooperate, and the locking sleeve can abut against the adjusting disk. In this way, when it is necessary to fix the position of the adjusting rod, the locking sleeve can be screwed onto the adjusting rod so that the locking sleeve abuts against the adjusting disk, and the friction between the locking sleeve and the adjusting disk is used to fix the position of the adjusting rod. When it is necessary to adjust the position of the adjusting rod, the locking sleeve can be loosened so that the locking sleeve is not in contact with the adjusting disk, so that the adjusting rod can slide freely in the arc groove to adjust the angle of the benchmark.
[0010] In some possible implementations, a limiting ring is fixedly sleeved on the circumferential outer surface of the locking sleeve, and when the locking sleeve abuts against the adjusting disk, the limiting ring abuts against the adjusting disk. In this way, the contact area between the locking sleeve and the adjusting disk can be increased, thereby increasing the friction between the locking sleeve and the adjusting disk. In this way, the stability and firmness of the locking can be improved.
[0011] In some possible implementations, a first rotating structure is provided on the rotating seat, a second rotating structure is provided on the mounting seat, and the mounting seat is rotatably connected to the rotating seat through the cooperation between the first rotating structure and the second rotating structure.

[0012] In some possible implementations, the first rotating structure is a hole body, and the second rotating structure is a shaft body. In this way, the first rotating structure and the second rotating structure have simple structures and are easy to assemble.
[0013] In some possible implementations, the mounting seat is provided with an insertion slot, a pole is inserted into the insertion slot, a threaded hole is provided on the mounting seat, the threaded hole penetrates a side wall of the insertion slot, and the engineering surveying pole fixing device further comprises a locking bolt, the locking bolt cooperates with the threaded hole, and the locking bolt can abut against the pole. In this way, the locking bolt can be tightened in the threaded hole so that the locking bolt abuts against the pole, and the friction between the pole and the locking bolt can be used to firmly fix the pole on the mounting seat.
[0014] In some possible implementations, there are multiple threaded holes and multiple locking bolts, and the multiple threaded holes are arranged in a one-to-one correspondence with the multiple locking bolts. In this way, multi-point fixation can be provided to further enhance the stability of the pole. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] See also Figure 1 The embodiment of the present application provides a device for fixing a benchmark for engineering surveying and mapping, including a base 1, a plurality of ground piles 2, a rotating seat 3, a mounting seat 4, an adjusting rod 5, an adjusting disk 6, and a locking member 7. The base 1 is provided with a plurality of fixing holes; the plurality of ground piles 2 are arranged one by one corresponding to the plurality of fixing holes, and each fixing hole is inserted with a corresponding ground pile 2; the rotating seat 3 is arranged on the base 1; illustratively, the rotating seat 3 and the base 1 can be fixedly connected by screw connection, clamping, welding, etc. Or the rotating seat 3 and the base 1 are an integrally formed part. The mounting seat 4 is used for detachably fixing and connecting the benchmark 9; the mounting seat 4 is rotatably connected to the rotating seat 3; one end of the adjusting rod 5 is fixedly connected to the mounting seat 4; and the adjusting disk 6 is arranged on the base 1. The connection method between the adjusting disk 6 and the base 1 can be designed with reference to the connection method between the rotating seat 3 and the base 1, which will not be repeated here. The adjusting disk 6 is provided with an arc groove 61 ; the other end of the adjusting rod 5 is passed through the arc groove 61 , and the other end of the adjusting rod 5 can slide along the extending direction of the arc groove 61 ; the locking member 7 is used to fix the position of the adjusting rod 5 in the arc groove 61 .
[0026] When in use, the base 1 is placed at the surveying site, and multiple ground stakes 2 are inserted into the multiple fixing holes on the base 1 to stabilize the base 1 on the ground. The benchmark 9 is fixedly mounted on the mounting seat 4. By moving the benchmark 9, the adjustment rod 5 can slide along the arc groove 61 to adjust the inclination angle of the benchmark 9. When the benchmark 9 is adjusted to a vertical state, the position of the adjustment rod 5 is locked by the locking member 7 to fix the angle of the benchmark 9 and ensure the stability of the benchmark 9 during the surveying process. In this way, the benchmark 9 can be firmly fixed on uneven terrain (such as ramps, slopes, etc.) to prevent the benchmark 9 from tilting, thereby ensuring the accuracy of the surveying data and the work efficiency of the staff, and reducing the difficulty of observation for the staff.
