Description

Technical Field

[0001] The utility model belongs to the field of surveying and mapping, and more specifically, particularly relates to a leveling structure of a surveying and mapping device. Background Art

[0002] Engineering surveying is the study of the relative positions of various geometric points in three-dimensional space. Its purpose is to reflect the buildings on the design drawings to the actual locations according to the relevant accuracy requirements, and to measure effective data including the plane position and elevation of the buildings as the basis for construction. At present, engineering surveying usually uses a level for physical measurement. Since the ground at the actual measurement location is usually uneven, the level will still have a large error after the tripod support frame is roughly leveled. In order to ensure the accuracy of the data, it is necessary to adjust the three sets of foot screws for fine leveling before measurement. The process is to use both hands to simultaneously rotate the two sets of foot screws that are perpendicular to the horizontal line of the level to complete the horizontal range leveling, and then adjust the remaining set of foot screws to complete the vertical range leveling until the horizontal bubble is in the middle position. It can be seen that the leveling operation requires both hands to operate the three sets of foot screws together, which is relatively cumbersome. In addition, the fine leveling structure of the level is fixedly installed on the support seat of the tripod by screwing multiple sets of bolts. The installation and disassembly of the fine leveling structure of the level is inconvenient, and the bolt parts are also easily lost after disassembly. Utility Model Content

DETAILED DESCRIPTION

[0022] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0023] like Figure 1-Figure 8As shown, the utility model provides a leveling structure of a surveying and mapping device, including a rotating seat 3; a level 1 is installed on the upper side of the rotating seat 3, the rotating seat 3 is rotatably connected to the upper side of the leveling seat 4, and a horizontal bubble ruler 2 is bonded to the upper side of the rotating seat 3; it also includes a leveling rod 9, a guide rod 12 and a spring 13; the front end of the spring 13 is welded and connected with a locking block 11, and the rear end of the spring 13 is welded and connected with a fixed disk 15; the fixed disk 15 is welded and connected to the guide rod 12, the outer side of the fixed disk 15 is rotatably connected with a rotating shell 5, and the lower side of the fixed disk 15 is clamped with a locking block 11 through the locking block 11. A tripod mounting base 6 is provided with three groups of through grooves which are connected vertically, and the through grooves are distributed in a circular array around the central axis of the tripod mounting base 6; a rotating sleeve 10 is rotatably connected to the upper side of the rotating shell 5, and a driving gear 7 is welded to the outer side of the rotating sleeve 10; the driving gear 7 is meshedly connected to a driven gear 14 on the outer side of the driving gear 7, and the driven gear 14 is welded to the outer side of the rotating sleeve 10; the rotating sleeve 10 is a cylindrical structure which is connected vertically, and a threaded structure is provided on the inner side of the cylindrical body of the rotating sleeve 10, and a leveling knob 8 is welded to the outer side of the rotating sleeve 10.

[0024] When the utility model is performing the leveling installation work of the surveying and mapping device, the three groups of through grooves of the fixing plate 15 are first docked on the three groups of through grooves of the tripod mounting seat 6. At this time, the locking block 11 goes deep into the three groups of through grooves of the tripod mounting seat 6 until the bottom end of the locking block 11 extends out of the bottom side of the through groove of the tripod mounting seat 6. Then the three groups of springs 13 respectively drive the three groups of locking blocks 11 to slide in the three groups of through grooves of the fixing plate 15 along the guide rod 12 until the bottom end of the L-shaped folding plate structure of the locking block 11 is attached to the bottom edge position of the through groove of the tripod mounting seat 6, completing the clamping installation work of the tripod mounting seat 6 and the fixing plate 15. Then the rotating seat 3 is manually rotated to make the observation direction of the level 1 perpendicular to the connecting direction of the center points of the driving gear 7 and the driven gear 14. Then the driving gear 7 is dialed by one hand. Since the driving gear 7 and the driven gear 14 are meshed with each other, the rotating sleeve 10 welded to the driving gear 7 and the rotating sleeve 10 welded to the driven gear 14 are synchronously rotated in the opposite direction. The spherical structure at the top of the leveling rod 9 pushes the leveling seat 4 to flip and level it laterally, and then the leveling knob 8 is manually turned, and the leveling knob 8 drives the welded rotating sleeve 10 to rotate, and the rotating sleeve 10 drives a group of leveling rods 9 on the front side to push the leveling seat 4 to perform longitudinal flipping and leveling work until the bubble of the horizontal bubble ruler 2 is in the center position. When the surveying and mapping work is completed, the rotating shell 5 is manually rotated, and the three groups of arc-surface protrusions on the inner side of the rotating shell 5 push the three groups of locking blocks 11 respectively during the rotation of the rotating shell 5, so that the locking blocks 11 overcome the elastic force of the spring 13 and move along the guide rod 12 toward the center of the fixed disk 15 until the locking blocks 11 are separated from the tripod mounting seat 6, completing the separation of the surveying and mapping device and the tripod.

[0025] In the disclosed embodiment, there are three groups of leveling rods 9, which are distributed in a circular array around the vertical center direction of the leveling seat 4. The outer side surfaces of the leveling rods 9 are provided with protrusions, and the top ends of the leveling rods 9 are provided with a spherical structure. The outer side surfaces of each group of leveling rods 9 are provided with a threaded structure, and the threads on the outer side surfaces of the leveling rods 9 are engaged with the threaded structure on the inner side of the cylinder of the rotating sleeve 10. The rotating sleeve 10 drives the leveling rods 9 to move up and down, so that the three groups of leveling rods 9 push the leveling seat 4 to adjust the tilt.

[0026] In the disclosed embodiment, three groups of circular hole grooves are provided on the lower side of the leveling seat 4, and the interior of each group of circular hole grooves is a spherical structure. The outer surface of the spherical structure at the top of the leveling rod 9 fits against the spherical structure inside the circular hole groove of the leveling seat 4. The spherical structure at the top of the leveling rod 9 and the spherical surface inside the circular hole groove of the leveling seat 4 form a fitting sliding structure, thereby completing the universal angle leveling movement of the leveling seat 4.

[0027] In the disclosed embodiment, there are three groups of locking blocks 11, and the locking blocks 11 are provided with through grooves extending front to back, and the guide rods 12 are inserted into the through grooves of the locking blocks 11. Each group of locking blocks 11 adopts an L-shaped folding plate structure. Through the L-folding plate structure of the locking blocks 11, the bottom ends of the locking blocks 11 are attached to the lower side surface of the tripod mounting seat 6, limiting the vertical movement of the fixed plate 15 on the tripod mounting seat 6, thereby completing the quick clamping and installation work of the locking blocks 11 on the fixed plate 15 and the tripod mounting seat 6.

[0028] In the disclosed embodiment, three groups of vertically penetrating through grooves are provided on the upper side of the fixed plate 15, and the through grooves are distributed in a circular array around the central axis of the fixed plate 15. The locking block 11 is inserted into the through grooves of the fixed plate 15, and the top of the locking block 11 is exposed on the upper side of the through grooves of the fixed plate 15. The inner side surfaces of each group of through grooves are welded with guide rods 12. The locking block 11 slides along the through grooves of the fixed plate 15 through the elastic force of the spring 13, thereby completing the locking and locking work of the locking block 11 at the through groove structure of the tripod mounting base 6.

[0029] In the embodiment of the present disclosure, three groups of arc-surface protrusions are provided on the inner side of the rotating shell 5, and the arc-surface protrusions are distributed in a ring array around the central axis of the rotating shell 5. When the rotating shell 5 rotates, the three groups of arc-surface protrusions simultaneously push the top of the locking block 11 to expose the upper side of the through groove of the fixed plate 15, so that the locking block 11 overcomes the elastic force of the spring 13, and the three groups of locking blocks 11 move toward the center position of the fixed plate 15 at the same time, so that the bottom of the L-shaped folding plate of the locking block 11 is separated from the lower side of the tripod mounting seat 6, and the fixed plate 15 is quickly removed from the tripod mounting seat 6. The lower side of each group of arc-surface protrusions is provided with a through hole, and the inner side of the through hole is provided with a groove. The protrusion on the outer side of the leveling rod (9) is embedded in the through hole groove of the arc-surface protrusion of the fixed plate 15, so that the leveling rod 9 moves vertically along the through hole groove of the fixed plate 15.

[0030] The installation, connection or setting methods of all the above components are common mechanical methods, such as welding, threaded connection, screw connection, etc., and the specific structures, models and coefficient indicators of all its components are its own technology, as long as it can achieve its beneficial effects, it can be implemented. The level 1 and horizontal bubble ruler 2 used above are common devices on the market. When you buy them back and use them, you only need to connect them according to the instruction manual purchased together, so I will not repeat them here.

[0031] The technical solution of the present invention is not limited to the scope of the embodiments of the present invention, and the technical contents not described in detail in the present invention are all well-known technologies.
