Description

Technical Field

[0001] This application relates to the field of surveying and mapping technology, and more specifically, to a field surveying and mapping auxiliary device. Background Technology

[0002] The construction engineering surveying section mainly includes the composition and use of surveying instruments, general surveying, industrial and civil building surveying, and other surveying. However, in the existing construction surveying field surveying process, depth measurement is directly measured by inserting a measuring rod. The measuring rod is prone to tilting and is not convenient to keep perpendicular to the ground. In addition, the distance between the measuring rod and the pit wall makes it inconvenient to read the data.

[0003] The prior art publication (announcement) document with the number CN214744626U provides a field surveying auxiliary device for building surveying. In the related technology of this device, by setting a measuring insertion rod, it is convenient to use the auxiliary gripping cylinder limit sleeve to extend upward to the limit position and then lock it in place by the limit anti-disengagement button, so as to facilitate the fixing of the insertion head into the ground and solve the problem that it is inconvenient to directly fix it to the ground as a surveying auxiliary target rod.

[0004] Although the existing technical solutions described above can achieve the relevant beneficial effects through the structure of the existing technology, they still have the following defects: Although the fixed insertion head can be inserted into the soil and placed vertically, its sharp structure makes it impossible to flexibly switch between placement and use on cement pavement or soil pavement.

[0005] In view of this, we propose a field survey auxiliary device. Utility Model Content

[0006] To address the problems mentioned in the background art, this application provides a field surveying auxiliary device.

[0007] The field survey auxiliary device provided in this application adopts the following technical solution:

[0008] A field survey auxiliary device, comprising:

[0009] Measuring rod body;

[0010] The docking post is threadedly connected to one end of the measuring rod body;

[0011] The drill bit string is rotatably connected inside the docking column;

[0012] The counterweight plate seat with a level is slidably connected between the drill bit column and the docking column, and is elastically limited by a spring.

[0013] By adopting the above technical solution, the counterweight plate seat and the docking column are elastically limited by spring components, allowing the counterweight plate seat to release the spring pressure and press together according to the road surface conditions of the area to be surveyed, thus exposing the drill bit column for flexible placement and use, thereby improving the flexibility of the device for surveying and placement.

[0014] As an optional solution to the technical solution of this application, a through groove is provided on one side of the docking post, and a protective sleeve is rotatably connected to the outside of the docking post with the through groove, and an inclined groove is provided on the outside of the protective sleeve.

[0015] By adopting the above technical solution, the protective sleeve with the inclined groove is used to shield and protect the external through groove of the docking column, thereby improving the safety protection effect of the through groove of the docking column.

[0016] As an optional solution to the technical solution of this application, the drill bit column is provided with a spiral extrusion groove on its outside, and an extrusion column is slidably extruded on one side of the extrusion groove, and the extrusion column is threadedly connected to one side of the counterweight plate.

[0017] By adopting the above technical solution, when the counterweight plate seat is pressed and limited, it drives the fixed extrusion column and the extrusion groove to slide and squeeze together, so that the drill bit column is limited to rotate, thereby drilling into the soil road surface for stable support and limitation.

[0018] As an optional solution to the technical solution of this application, the counterweight plate has a ring-shaped structure with multiple storage slots on one side, and a top support plate is slidably fitted in the storage slot. An adjusting screw is rotatably connected to one side of the top support plate, and the adjusting screw is threadedly adapted to the counterweight plate.

[0019] By adopting the above technical solution, the counterweight plate is lifted by adjusting the screw thread to limit the movement of the top support plate, so that the counterweight plate is leveled and the counterweight plate is placed stably.

[0020] As an optional solution to the technical solution in this application, a plurality of protruding cones are fixedly connected to one side of the top support plate.

[0021] By adopting the above technical solution, the protruding cone head can increase the frictional resistance of the top support plate, making the top support plate more stable in contact with the ground.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. This application utilizes a spring-loaded elastic limit between the counterweight plate and the docking column, allowing the counterweight plate to release and press according to the road surface conditions of the area to be surveyed, exposing the drill bit for flexible placement and use. This improves the flexibility of the device's placement and use. When the counterweight plate is pressed and limited, it can drive the connected and fixed extrusion column and extrusion groove to slide and extrude, causing the drill bit to rotate and thus drill into the soil road surface for stabilization.

[0024] 2. This application improves the safety protection effect of the through groove of the docking column by using a protective sleeve with an inclined groove to shield and protect the external through groove of the docking column. Attached Figure Description

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] Reference Figure 1-4 One type of field surveying auxiliary device described in this application includes:

[0032] Measuring rod body 1;

[0033] The docking post 2 is threadedly connected to one end of the measuring rod body 1;

[0034] Drill bit column 3 is rotatably connected inside docking column 2;

[0035] The counterweight plate 4, which is equipped with a level, is slidably connected between the drill bit column 3 and the docking column 2, and is elastically limited by a spring.

[0036] This field survey auxiliary device utilizes a spring-loaded elastic limit between the counterweight plate 4 and the docking column 2, allowing the counterweight plate 4 to release the spring pressure and press down according to the road surface conditions of the area to be surveyed, thus exposing the drill bit column 3 for flexible placement and use, thereby improving the flexibility of the device's survey placement and use.

[0037] Reference Figure 2 and Figure 1 In the field survey auxiliary device described in this application embodiment, a through groove is provided on one side of the docking column 2, and a protective sleeve 21 is rotatably connected to the outside of the docking column 2 with the through groove, and an inclined groove is provided on the outside of the protective sleeve 21.

[0038] This field survey auxiliary device improves the safety protection effect of the through groove of the docking column 2 by using the protective sleeve 21 with the inclined groove to shield and protect the external through groove of the docking column 2.

[0039] Reference Figure 3 and Figure 2 In the field survey auxiliary device described in this application embodiment, the drill bit column 3 has a spiral extrusion groove 31 on its outside. An extrusion column 32 is slidably extruded on one side of the extrusion groove 31 and is threadedly connected to one side of the counterweight plate 4.

[0040] This field survey auxiliary device uses the counterweight plate 4 to limit and press, which drives the fixed extrusion column 32 and the extrusion groove 31 to slide and squeeze together, so that the drill bit column 3 is limited to rotate, thereby drilling into the soil road surface for stable support and limitation.

[0041] Reference Figure 4 and Figure 1 In the field survey auxiliary device described in this application embodiment, the counterweight plate 4 has a ring structure with multiple storage slots on one side. A top support plate 41 is slidably fitted in the storage slot. An adjusting screw 42 is rotatably connected to one side of the top support plate 41. The adjusting screw 42 is threadedly matched with the counterweight plate 4. Multiple protruding cones are fixedly connected to one side of the top support plate 41.

[0042] This field survey auxiliary device uses the adjusting screw 42 to push the top support plate 41 to limit and lift the counterweight plate 4 during thread adjustment, so that the counterweight plate 4 is leveled and the counterweight plate 4 is placed stably. The protruding cone can increase the frictional resistance of the top support plate 41, making the top support plate 41 more stable in contact with the ground.

[0043] Working principle: When the device needs to be placed on a hard surface for surveying, the counterweight plate 4 is placed against the surface, and the adjusting screw 42 in the corresponding position is rotated appropriately according to the level installed on its surface, pushing the top support plate 41 to lift the counterweight plate 4, thereby achieving the horizontal calibration of the counterweight plate 4.

[0044] When placed on a soft surface, the operator holds the measuring rod body 1 and presses it down. At this time, the counterweight plate 4 is squeezed against the soil surface, which compresses the spring piece sleeved on the outside of the docking column 2 and exposes the drill bit column 3. When the counterweight plate 4 is displaced, it drives the fixed extrusion column 32 to slide and squeeze with the drill bit column 3, pushing the drill bit column 3 to rotate and drill into the soil layer and fix it.

[0045] Next, based on the level indicator mounted on the surface of the counterweight plate 4, rotate the adjusting screw 42 in the corresponding position appropriately to push the top support plate 41 to lift the counterweight plate 4 and calibrate the counterweight plate 4 to a horizontal position.
