Description

Technical Field

[0001] This utility model relates to the field of land surveying technology, specifically a surveying and mapping device that can be used for land surveying in different terrains. Background Technology

[0002] Land surveying refers to the technical service work that involves determining survey projects in stages and batches according to the land use needs of phased development plans and construction projects, measuring land boundaries and extent on-site, mapping the current land use status, calculating land area, and providing scientific and accurate basic data for land use approval, cadastral management, land development and reclamation by the land and resources administrative departments. Surveying equipment is required in land surveying.

[0003] Chinese patent CN220602547U discloses a land surveying device applicable to different terrains. This surveying device pushes a movable sleeve out to the outside of the ground, then pushes out a support plate, connects the two support plates laterally, and then rotates the support plate to adjust the angle so that it can fit the ground, increasing the contact area with the ground and preventing sinking when in contact with softer ground, thus improving stability and adapting to different terrains. This effectively improves the flexibility and convenience of use.

[0004] The aforementioned patents involve cumbersome operation and complex structure when using support plates to support the ground. Furthermore, the support plates protrude from the outside of the tripod, making it easy for the surveying equipment to be bumped and injured during transport. In addition, the surveying instrument lacks external protection, making it susceptible to damage from bumps during handling. Utility Model Content

[0005] The purpose of this invention is to provide a land surveying and mapping device that can be used in different terrains, effectively solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution.

[0007] A land surveying and mapping device applicable to various terrains includes a housing. Inside the housing, a lifting plate is installed via a lifting mechanism. A surveying instrument is mounted on the upper side of the lifting plate, and a top cover is installed on the top of the surveying instrument. A tripod is installed at the bottom of the housing. Fixed shafts are installed on the outer surfaces of the tripod near its bottom. A flap is installed on the outer surfaces of the two fixed shafts. One of the fixed shafts has an external thread on its outer surface, and a fastening nut is installed on the outer surface of the external thread.

[0008] Therefore, the design of the housing and lifting mechanism allows the surveying instrument to be retracted into the housing when not in use, with the top cover covering the top of the housing. This provides a closed storage space for the surveying instrument, preventing damage from bumps during transport and improving its protective performance. When the flap is needed for support, the fastening nut can be loosened first, releasing the flap and allowing it to be flipped to a suitable angle to fit against the ground. Then, the fastening nut can be tightened to secure the flap, preventing it from sinking when in contact with softer ground and improving stability to adapt to different terrains. The structure is simple and easy to operate. When not in use, the flap can be folded onto the outer surface of the tripod, reducing protruding parts and preventing bumps and injuries.

[0009] Furthermore, the lifting mechanism includes a U-shaped inner groove inside the side wall of the housing. Threaded rods are rotatably installed inside the vertical grooves on both sides of the U-shaped inner groove. Drive nuts are installed on the outer surface of the threaded rods. Communicating grooves are opened on both sides of the inner wall of the housing in the vertical direction. Connecting blocks are installed on the outer surface of the drive nuts, and the ends of the connecting blocks pass through the communicating grooves and connect to the lifting plate. A drive mechanism that drives the lifting mechanism is installed inside the horizontal groove at the bottom of the U-shaped inner groove.

[0010] Furthermore, the drive mechanism includes a motor installed at the bottom of the housing, the output shaft of the motor passing through the interior of the U-shaped inner groove and having a first bevel gear installed thereon, a rotating shaft rotatably installed inside the bottom transverse groove of the U-shaped inner groove, a second bevel gear installed on the outer surface of the rotating shaft near its middle part, and the second bevel gear meshing with the first bevel gear, a third bevel gear installed on the outer surfaces of both ends of the rotating shaft along its length, and a fourth bevel gear installed at the bottom of the threaded rod, and the fourth bevel gear meshing with the third bevel gear.

[0011] Furthermore, a limit block is installed at the end of the fixed shaft whose surface is provided with external threads.

[0012] Furthermore, a support rod is installed on the upper surface of the lifting plate, and the surveying instrument is installed on top of the support rod.

[0013] Furthermore, a groove is provided on the upper surface of the housing, and a sealing gasket is provided inside the groove, with the upper surface of the sealing gasket protruding from the upper surface of the housing.

[0014] Furthermore, a bearing is mounted on the outer surface of the threaded rod, and the outer surface of the bearing is connected to the inner wall of the U-shaped inner groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0016] 1. This utility model, through the design of the housing and lifting mechanism, allows the surveying instrument to be retracted into the housing when not in use, with the top cover covering the top of the housing, thus providing a closed storage space for the surveying instrument and preventing damage caused by bumps during transportation, thereby improving the protective performance of the surveying instrument.

[0017] 2. This utility model allows the flap to be released from its fixed position by loosening the fastening nut, thus enabling it to be flipped to a suitable angle and fit against the ground. The flap can then be fixed by tightening the fastening nut again, preventing it from sinking when in contact with softer ground, improving stability and adapting to different terrains. It also features a simple structure, is easy to operate and carry, and can be folded onto the outer surface of the tripod when not in use, thereby reducing protruding parts and preventing bumps and injuries.

Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0027] Please see Figures 1-5 This utility model provides a land surveying and mapping device applicable to different terrains, comprising a housing 100. Inside the housing 100, a lifting plate 101 is installed via a lifting mechanism 200. A surveying instrument 102 is installed on the upper side of the lifting plate 101, and a top cover 107 is installed on the top of the surveying instrument 102. A tripod 103 is provided at the bottom of the housing 100. Fixed shafts 104 are installed on the outer surfaces of the two sides near the bottom of the tripod 103. A flap 105 is installed on the outer surfaces of the two fixed shafts 104. One of the fixed shafts 104 has an external thread on its outer surface, and a fastening nut 106 is installed on the outer surface of the external thread.

[0028] In use, first open the tripod 103 to support the ground. If the ground is soft and prone to sinking, loosen the fastening nut 106 first. At this time, the flip plate 105 is released from its fixed position, so it can be flipped to a suitable angle and can fit against the ground. Then tighten the fastening nut 106 to fix the flip plate 105, so that it will not sink when in contact with soft ground, improving stability and adapting to different terrains. Then, use the lifting mechanism 200 to lift the surveying instrument 102 to the outside of the housing 100. When used for surveying, after the surveying is completed, the lifting mechanism 200 lowers the surveying instrument 102 into the housing 100, and the top cover 107 is placed on top of the housing 100. This provides a closed storage space for the surveying instrument 102, preventing damage caused by bumps during transportation and improving the protection of the surveying instrument 102. Then, the fastening nut 106 is loosened to flip the flap 105 so that it is flush with the tripod 103, thereby reducing the protruding parts and preventing bumps that could cause injury.

[0029] Specifically, the lifting mechanism 200 includes a U-shaped inner groove 201 formed inside the side wall of the housing 100. Threaded rods 202 are rotatably mounted inside the vertical grooves on both sides of the U-shaped inner groove 201. Drive nuts 203 are mounted on the outer surface of the threaded rods 202. Connecting grooves 204 are formed vertically on both sides of the inner wall of the housing 100. Connecting blocks 205 are mounted on the outer surface of the drive nuts 203, and the ends of the connecting blocks 205 pass through the connecting grooves 204 and connect to the lifting plate 101. The inner side of the bottom horizontal groove of the U-shaped inner groove 201... The unit is equipped with a drive mechanism 300 that is in transmission cooperation with the lifting mechanism 200. Due to the cooperation of the connecting groove 204 and the connecting block 205, the drive nut 203 can be limited. Therefore, when the two threaded rods 202 are driven to rotate simultaneously by the drive mechanism 300, the drive nut 203 can be driven to rise and fall vertically along the surface of the threaded rod 202 under the drive of the threaded connection. Thus, the lifting plate 101 can be driven to rise and fall through the connecting action of the connecting block 205, thereby achieving the purpose of driving the surveying instrument 102 to rise and fall.

[0030] Specifically, the drive mechanism 300 includes a motor 301 installed at the bottom of the housing 100. The output shaft of the motor 301 extends into the interior of the U-shaped inner groove 201 and is fitted with a first bevel gear 302. A rotating shaft 303 is rotatably mounted inside the bottom transverse groove of the U-shaped inner groove 201. A second bevel gear 304 is mounted on the outer surface of the rotating shaft 303 near its middle portion, and the second bevel gear 304 meshes with the first bevel gear 302. A third bevel gear 305 is mounted on the outer surfaces of both ends of the rotating shaft 303 along its length. A fourth bevel gear 306 is mounted on the bottom of the threaded rod 202, and the fourth bevel gear 306 meshes with the third bevel gear 305. When the motor 301 is started, its output shaft drives the first bevel gear 302 to rotate. Since the first bevel gear 302 meshes with the second bevel gear 304, it can drive the rotating shaft 303 to rotate. Since the third bevel gear 305 and the fourth bevel gear 306 mesh with each other, it is possible to simultaneously drive the two threaded rods 202 to rotate.

[0031] Specifically, a limiting block 400 is installed at the end of the fixed shaft 104 with external threads on its surface. The limiting block 400 can prevent the fastening nut 106 from falling off the fixed shaft 104 and being lost.

[0032] Specifically, a support rod 500 is installed on the upper surface of the lifting plate 101, and the surveying instrument 102 is installed on the top of the support rod 500. Since the lifting plate 101 can only be raised and lowered inside the housing 100 and cannot rise to the outside of the housing 100, the support rod 500 can compensate for the installation height of the surveying instrument 102, so that when the lifting plate 101 is raised to the highest position, the surveying instrument 102 can be used outside the housing 100.

[0033] Specifically, a groove is provided on the upper surface of the housing 100, and a sealing gasket 600 is provided inside the groove. The upper surface of the sealing gasket 600 protrudes from the upper surface of the housing 100. By setting the sealing gasket 600, on the one hand, it can play a buffering role when the top cover 107 contacts the housing 100, and on the other hand, it can improve the sealing between the top cover 107 and the housing 100, improve the waterproof performance, and further strengthen the protection of the surveying instrument 102.

[0034] Specifically, a bearing 700 is installed on the outer surface of the threaded rod 202, and the outer surface of the bearing 700 is connected to the inner wall of the U-shaped inner groove 201. The bearing 700 provides a support point for the threaded rod 202, making it more stable and smooth when rotating, thus ensuring the stability of the surveying instrument 102 when lifting and lowering.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
