Description

Technical Field

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

[0002] Construction engineering surveying refers to the on-site measurement of construction sites, structures and terrain to obtain relevant construction data such as building area, shape and terrain, so as to facilitate subsequent housing design and construction planning. At present, construction engineering surveying and mapping mostly uses a tripod to support the top surveying and mapping total station for engineering surveying and mapping. Before the surveying and mapping total station performs surveying and mapping work, it is necessary to perform rough and fine leveling and calibration on the surveying and mapping total station to ensure that accurate measurement data is obtained. In the rough leveling and adjustment work, the surveying and mapping personnel need to hold the legs of the tripod and loosen the clamping bolts, and pull and adjust the length of the legs to achieve rough leveling and adjustment. During this operation, since the clamping bolts are in the middle of the legs and the calibration circular bubble is located on the upper side of the top surveying and mapping total station, the surveying and mapping personnel need to constantly bend over and pull and adjust the legs after loosening the clamping bolts. As a result, the surveying and mapping personnel cannot simultaneously observe the center position of the circular bubble during the adjustment, and the leveling operation is cumbersome. In addition, on a relatively smooth ground, the sharp cones at the feet of the tripod legs make it difficult to stably fix the tripod. Slightly touching a group of legs will cause leveling errors, affecting the accuracy of surveying and mapping. Utility Model Content

DETAILED DESCRIPTION

[0024] 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.

[0025] like Figure 1-Figure 9 As shown, the utility model provides a construction site surveying and mapping device, including a support column 4, a foot screw 16 and a total station mounting bolt 17; the total station mounting bolt 17 is screwed to the lower side of the total station surveying and mapping instrument 11 through a thread; the top of the support column 4 is welded to the lower side of the bottom mounting plate 15, and the bottom of the support column 4 is welded to the upper side of the support plate 10; the foot screw 16 is screwed to the fixing seat 18 through a thread, and the foot screw 16 is rotatably connected to the bottom mounting plate 15; it also includes a fixed leg frame 2, a connecting rod 3, a support column 4, a foot seat 7, an adjustment knob 9, a liquid bubble calibration plate 12, an extension turntable 13 and a rubber pad 19; the fixed leg frame 2 is hinged on the outer side surface of the support plate 10; the adjusting knob 9 is welded and connected to the non-threaded end of the outer side surface of the threaded adjusting rod 8; the extension turntable 13 is connected to the top of the threaded column 14 by bolts; the connecting rod 3 is hinged on the outer side surface of the movable column 5, and the connecting rod 3 is hinged to the fixed leg frame 2; the foot seat 7 is hinged at the bottom end of the movable leg frame 1, and the foot seat 7 is screwed to the fixing bolt 6 by threads; the rubber pad 19 is bonded to the foot seat 7; the bubble calibration disk 12 is bonded to the upper side surface of the total station surveying instrument 11; a through hole is provided at the center position of the upper side surface of the support plate 10, and the movable column 5 is rotatably connected in the through hole of the support plate 10.

[0026] When the utility model is performing the installation and rough leveling of the total station, the extension turntable 13 is first manually rotated, and the extension turntable 13 drives the threaded column 14 to rotate. Since the threaded through hole of the movable column 5 is meshed with the threaded thread of the outer side of the threaded column 14, the threaded column 14 drives the movable column 5 to move vertically downward. At this time, the movable column 5 pushes the three groups of connecting rods 3 hinged on the outer side to flip and move at the same time, and the three groups of connecting rods 3 simultaneously push the three groups of fixed leg frames 2 to flip and move around the hinge point of the support plate 10, so that the three groups of fixed leg frames 2 are respectively equipped with the movable leg frames 1 to open and stretch outward, and then the movable leg frame 1 is placed on the ground. Since the foot seat 7 is hinged at the bottom end of the movable leg frame 1, the foot seat 7 can be converted to touch the ground according to the smoothness and roughness of the ground. If the ground for surveying and positioning is a rough ground with sand, first flip the foot seat 7 to the side where the cone tip structure faces the ground, and then insert the fixing bolt 6 into the through hole of the movable leg frame 1 and screw it into the threaded hole of the foot seat 7, and then The end structure is inserted into the sand for fixed installation. If the ground for surveying and positioning is smooth, first remove the fixing bolt 6 from the threaded through hole of the foot 7, then flip the foot 7 to the side where the rubber pad 19 faces the ground, and use the rubber pad 19 to increase the friction of the foot 7 on the smooth ground, so that the total station can be stably installed on the smooth surface, dock the total station surveying instrument 11 at the total station mounting bolt 17, and then screw the mounting threaded hole of the total station surveying instrument 11 with the total station mounting bolt 17 to complete the total station. The instrument is installed and set up, and then the three groups of adjusting knobs 9 are manually turned. The three groups of adjusting knobs 9 respectively drive the threaded adjusting rods 8 to rotate. Since the threads on the outer side of the threaded adjusting rods 8 are engaged with the threaded deep holes on the top of the movable leg frame 1, the threaded adjusting rods 8 drive the movable leg frame 1 to extend outward or retract inward along the through grooves of the fixed leg frame 2, thereby changing the combined length of the movable leg frame 1 and the fixed leg frame 2, until the round bubble in the liquid bubble calibration disk 12 is in the center position, completing the rough leveling adjustment of the leg frame to the total station.

[0027] In the disclosed embodiment, the fixed leg frame 2 is provided with a small through groove and a large through groove which pass through from top to bottom, and the adjusting knob 9 is embedded in the small through groove. The top of the large through groove of the fixed leg frame 2 is provided with a through hole, and the bottom of the large through groove of the fixed leg frame 2 is provided with a rectangular through groove. The movable leg frame 1 is inserted into the rectangular through groove of the fixed leg frame 2, and the outer side surface of the threaded adjusting rod 8 is rotatably connected to the through hole of the fixed leg frame 2. Through the large through groove and small through groove structure of the fixed leg frame 2, the telescopic and pull-out structure of the movable leg frame 1 and the fixed leg frame 2 is made more compact, and the operation layout of the adjusting knob 9 is more reasonable, which is convenient for surveying and mapping personnel to perform rough leveling calibration operations.

[0028] In the disclosed embodiment, there are three groups of movable leg frames 1, and each group of movable leg frames 1 is provided with a through hole near the bottom end, and the fixing bolt 6 can be inserted into the through hole of the movable leg frame 1. The top of each group of movable leg frames 1 is provided with a threaded deep hole, and the outer side surface of the threaded adjustment rod 8 is threadedly engaged and connected to the threaded deep hole of the movable leg frame 1. The adjusting knob 9 drives the threaded adjustment rod 8 to rotate, so that the movable leg frame 1 can be telescopically and slidably adjusted along the through groove of the fixed leg frame 2 to change the horizontal degree of the total station. The adjustment structure is reasonable and compact, and the adjustment operation is simple and convenient. The front and rear sides of the movable leg frame 1 are provided with convex plates near the top. When the movable leg frame 1 reaches the elongation limit, the convex plate of the movable leg frame 1 fits against the bottom side surface inside the large through groove of the fixed leg frame 2 to prevent the movable leg frame 1 from separating from the fixed leg frame 2.

[0029] In the disclosed embodiment, the bottom end of the foot seat 7 is a cone tip structure, and a threaded hole is provided on the front side of the foot seat 7. The through hole of the movable leg frame 1 is opposite to the threaded hole of the foot seat 7 front and back, and the fixing bolt 6 is screwed into the threaded hole of the foot seat 7 through a thread. If the total station is set up on sand or relatively rough ground, the cone tip structure of the foot seat 7 can be inserted into the ground, making the installation of the total station more stable. If the total station is set up on smooth ground, remove the fixing bolt 6 so that the rubber pad 19 bonded to the foot seat 7 contacts the smooth ground, thereby increasing friction and preventing the movable leg frame 1 from moving.

[0030] In the disclosed embodiment, a threaded through hole structure that passes through the support plate 10 from top to bottom is provided at the center position of the support plate 10, and a threaded column 14 is meshedly connected in the threaded through hole of the support plate 10. When the threaded column 14 rotates, the support plate 10 moves vertically up and down along the threaded column 14 and drives the connecting rod 3 to complete the extension and erection and retraction and storage of the fixed leg frame 2. The self-locking characteristics of the thread of the threaded column 14 are used to prevent the fixed leg frame 2 from flipping over due to collision.

[0031] In the embodiment of the present disclosure, a ring plate is provided at the center of the bottom end of the threaded column 14. The diameter of the ring plate is larger than the diameter of the threaded column 14. The ring plate is used to limit the movement of the movable column 5 to prevent the movable column 5 from falling off the threaded column 14 when the movable column 5 moves to the bottom end of the threaded column 14.

[0032] 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, and can be implemented as long as it can achieve its beneficial effects. The total station surveying instrument 11 and liquid bubble calibration disk 12 used above are common components on the market. When purchased and used, they can be used by simply connecting them according to the instruction manual purchased together, so they will not be repeated here.

[0033] 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.
