Description

Technical Field

[0001] The present application relates to the field of land area surveying and mapping, and in particular, to a measuring device for land area surveying and mapping. Background Art

[0002] Land area surveying mainly uses surveying instruments to measure land area. These surveying instruments include total stations. When measuring, the bracket of the traditional total station is placed on the ground. There is generally no way to fix the bracket to the ground. In addition, when measuring land, the geology of the measuring site is relatively soft, which leads to poor stability in the installation of the total station, thus affecting normal measurement operations.

[0003] There is a need for a measuring device for land area surveying and mapping with high stability. Summary of the invention

[0006] Through the above technical solution, the measuring instrument is set up on the surveying site through the bracket, and the bottom plate is in contact with the ground, which increases the contact area between the pole and the ground, thereby improving the stability of the bracket. At the same time, by stepping on the plug rod, the plug rod can be inserted into the ground, and the limit pin is stuck on the peripheral wall of the sleeve, thereby limiting the movement of the plug rod and further improving the stability of the pole. After the surveying is completed, the elastic force of the spring can make the plug rod move upward and be pulled out of the ground, so that the pole can be removed from the ground easily.

[0007] Preferably, a through hole is provided on the outer periphery of the insertion rod and passes through the insertion rod in a direction perpendicular to the axis of the insertion rod, the limit pin is embedded in the through hole of the insertion rod, the spring seat is located on the upper side of the limit pin, and a pedal is fixed to the upper end surface of the insertion rod.

[0008] Through the above technical solution, the provision of the pedal makes it convenient for the operator to step on the upper end of the insertion rod, which is conducive to the rapid insertion of the insertion rod into the ground.

[0009] Preferably, a limiting groove penetrating the circumferential wall of the sleeve is provided, the limiting groove consists of a horizontal portion and a vertical portion and is "L" shaped, the upper end of the vertical portion of the limiting groove is open, and the limiting pin can slide along the limiting groove.

[0010] Through the above technical solution, the limiting pin slides along the limiting groove, and when the limiting pin is inserted into the horizontal part of the limiting groove, the movement of the insertion rod is limited.

[0012] Through the above technical solution, the clamping block is embedded in the clamping groove, thereby realizing the connection between the rack rod and the mounting seat.

[0013] Preferably, a screw is fixed on one side of the clamping block away from the fixing seat, the screw passes through the through slot, a pressure plate is sleeved on the screw, a nut is threadedly connected on the outer periphery of the screw, and the pressure plate can abut against the surface of the clamping seat.

[0014] Through the above technical solution, the nut is tightened so that the pressure plate abuts against the surface of the clamping seat, thereby ensuring the connection stability between the clamping block and the mounting seat.

[0015] Preferably, a land area surveying and mapping comprises the following steps:

[0016] S1, insert the clamping block into the clamping groove, tighten the nut, and then the pressure plate clamps the clamping seat, so that the clamping block is fixed in the clamping seat.

[0017] S2, at this time, the bottom plate contacts the ground, the operator steps on the pedal, so that the insertion rod is inserted downward into the ground, the spring is compressed and accumulates force, the limit pin slides into the vertical part of the limit groove, and the pedal is turned, so that the limit pin slides into the horizontal part of the limit groove in the horizontal direction, thereby limiting the vertical sliding of the insertion rod, thereby increasing the stability of the pole on the ground.

[0018] S3. When the measurement is completed, reverse the pedal so that the limit pin rotates to the vertical part of the limit slot with the rod as the center, and then release the pedal. The pedal will automatically pull upward and away from the ground under the elastic force of the spring, making it easier to remove the pole from the ground.

[0019] The beneficial effect of the present application is that it provides a measuring device for land area surveying and mapping with high specific stability. BRIEF DESCRIPTION OF THE DRAWINGS
