[0031] Embodiment 1:

[0032] See also Figure 1-5 The utility model describes the above technical solution in detail through the following embodiments:

[0033] A field surveying and mapping device for engineering cost, comprising:

[0034] The surveying and mapping instrument 1 has a mounting platform 2 disposed below the surveying and mapping instrument 1 . The mounting platform 2 is connected to three sets of brackets 3 . The brackets 3 are used to support the mounting platform 2 .

[0035] The surveying and mapping instrument 1 adopts a well-known surveying and mapping equipment.

[0036] The mounting platform 2 comprises a mounting plate 22 , in which a connector 25 is slidably mounted. An adjusting screw 27 is arranged in the connector 25 and connected via a driving assembly. The driving assembly is used to drive the adjusting screw 27 to rotate.

[0037] The mounting plate 22 is made of metal. A circular through hole is provided in the middle of the mounting plate 22, and the through hole is used for threaded connection with the surveying and mapping instrument 1.

[0038] The connector 25 is L-shaped, and a rotating shaft 26 is welded to the head of the connector 25 .

[0039] The angle between the head and the tail of the connector 25 is 120°, and the connector 25 is made of metal. The diameter of the rotating shaft 26 is the same as the thickness of the connector 25 , and the length of the rotating shaft 26 is greater than the width of the connector 25 .

[0040] A slide groove 23 is provided in the mounting plate 22, and a top cover 21 is fixedly installed on the top of the mounting plate 22 by bolts. The head of the connector 25 is slidably installed in the slide groove 23 through the slide groove cover 24. The head of the connector 25 can slide in the slide groove 23, and can be rotated through the rotating shaft 26 when the connector 25 slides to the edge of the slide groove 23.

[0041] The depth of the chute 23 is the same as the thickness of the head of the connector 25, and the width of the chute 23 is the same as the length of the rotating shaft 26. The chute cover 24 is fixedly installed at the opening of the chute 23 by bolts, and the spacing of the chute cover 24 is the same as the width of the connector 25.

[0042] When the head of the connector 25 and the rotating shaft 26 are fully inserted into the chute 23, the mounting plate 22 cooperates with the top cover 21 to clamp the head of the connector 25, and the connector 25 cannot rotate. When the head of the connector 25 and the rotating shaft 26 slide to the chute cover 24, the connector 25 can rotate downward around the rotating shaft 26.

[0043] The driving assembly includes a hand wheel 29 , which is fixedly connected to an adjusting screw 27 via a worm gear transmission device 28 , and the adjusting screw 27 is inserted into an adjusting bracket 32 ​​.

[0044] The rotating hand wheel 29 can drive the adjusting screw 27 to rotate through the worm gear transmission device 28 . Due to the self-locking property of the worm gear transmission device 28 , the adjusting screw 27 cannot drive the rotating hand wheel 29 to rotate.

[0045] The bracket 3 includes a main bracket 31 , which is fixedly connected to the connector 25 by bolts. An adjustment bracket 32 ​​is slidably installed in the main bracket 31 . A quick adjustment component 4 is provided on the top of the adjustment bracket 32 ​​, and the quick adjustment component 4 is connected to the adjustment screw 27 .

[0046] The main support 31 and the adjustment support 32 can be made of wood or metal. The bottom end of the adjustment support 32 passes through the bottom of the main support 31 and is fixed with a support foot 33 by bolts. The support foot 33 is made of metal.

[0047] The quick adjustment assembly 4 includes a fixed plate 41 , on which a sliding sleeve 42 is fixedly provided. The sliding sleeve 42 is connected to a threaded sleeve 43 via a clamping device. The clamping device is used to drive the threaded sleeve 43 to be threadedly connected or disconnected with the adjusting screw 27 .

[0048] The fixed plate 41 and the sliding sleeve 42 are welded. The fixed plate 41, the sliding sleeve 42 and the threaded sleeve 43 are all made of metal. The fixed plate 41 is fixedly mounted on the top of the adjustment bracket 32 ​​by bolts, and a circular through hole is provided in the center of the fixed plate 41.

[0049] The inner side surfaces of the sliding sleeve 42 and the threaded sleeve 43 are semicircular, and the inner diameters of the sliding sleeve 42 and the threaded sleeve 43 are the same as the outer diameter of the adjusting screw 27 . The inner wall of the sliding sleeve 42 is smooth, and the inner wall of the threaded sleeve 43 is provided with threads, which are adapted to the threads of the adjusting screw 27 .

[0050] The inner wall of the sliding sleeve 42 always abuts against the side of the adjusting screw 27. When the inner walls of the sliding sleeve 42 and the threaded sleeve 43 abut against the side of the adjusting screw 27 at the same time, the thread of the threaded sleeve 43 meshes with the thread of the adjusting screw 27. At this time, rotating the adjusting screw 27 can drive the threaded sleeve 43 to move along the axis of the adjusting screw 27, thereby driving the adjusting bracket 32 ​​to move through the sliding sleeve 42 and the fixed plate 41, and realizing fine adjustment of the adjusting bracket 32.

[0051] When the threaded sleeve 43 is disengaged from the adjusting screw 27 , the sliding sleeve 42 can move freely along the axial direction of the adjusting screw 27 , thereby realizing rapid adjustment of the adjusting bracket 32 ​​.

[0052] The clamping device includes a guide rod 45 , one end of which is welded to the sliding sleeve 42 , and the other end of which passes through the threaded sleeve 43 and is clamped to a limit plate 46 . A spring 44 is sleeved on the guide rod 45 and located between the sliding sleeve 42 and the threaded sleeve 43 .

[0053] The two ends of the spring 44 are respectively against the sliding sleeve 42 and the threaded sleeve 43. Under the elastic force of the spring 44, the sliding sleeve 42 and the threaded sleeve 43 move away from each other. Since the sliding sleeve 42 is fixedly installed on the top of the adjustment bracket 32 ​​by the fixing plate 41 and cannot move, the threaded sleeve 43 moves along the guide rod 45.

[0054] A locking disc 47 is rotatably mounted between the threaded sleeve 43 and the limiting plate 46 . A locking protrusion 48 is provided on the locking disc 47 near the limiting plate 46 . A rotating rod 49 is fixedly mounted on the middle of the locking disc 47 by screws. The rotating rod 49 passes through the limiting plate 46 .

[0055] Twisting the rotating rod 49 can drive the locking plate 47 to rotate, thereby driving the locking protrusion 48 to rotate. When the locking protrusion 48 is located directly below the limit plate 46, the locking plate 47 presses the threaded sleeve 43 toward the sliding sleeve 42, so that the threaded sleeve 43 cooperates with the sliding sleeve 42 to clamp the adjusting screw 27 and squeeze the spring 44 at the same time.

[0056] When the locking protrusion 48 is located at the upper and lower sides of the limit plate 46, the threaded sleeve 43 moves along the guide rod 45 toward the limit plate 46 under the elastic force of the spring 44. The threaded sleeve 43 is separated from the adjusting screw 27.

[0057] When the operator of this embodiment uses the device, he rotates the bracket 3 outward and drives the connecting head 25 to rotate upward at the same time, until the top surface of the connecting head 25 abuts against the top cover 21.

[0058] The connector 25 is pushed toward the center of the mounting plate 22 until the connector 25 and the connector 25 slide into the deepest part of the slide slot cover 24. At this time, the connector 25 cannot rotate, thereby realizing the rapid opening and fixing of the bracket 3.

[0059] The rotating rod 49 is turned to drive the locking plate 47 to rotate, thereby driving the locking protrusion 48 to rotate. The locking protrusion 48 is driven to rotate to the upper and lower sides of the limit plate 46, and the threaded sleeve 43 moves along the guide rod 45 toward the limit plate 46 under the elastic force of the spring 44. The threaded sleeve 43 is separated from the adjusting screw 27.

[0060] The threaded sleeve 43 is disengaged from the adjusting screw 27 , and the sliding sleeve 42 can move freely along the axial direction of the adjusting screw 27 , thereby realizing rapid adjustment of the adjusting bracket 32 ​​.

[0061] After the adjustment bracket 32 ​​is roughly adjusted into position, the rotating rod 49 is turned to drive the locking protrusion 48 to rotate to just below the limit plate 46, and the locking disk 47 squeezes the threaded sleeve 43 toward the sliding sleeve 42, so that the threaded sleeve 43 cooperates with the sliding sleeve 42 to clamp the adjusting screw 27 and squeeze the spring 44 at the same time.

[0062] When the three adjustment brackets 32 are roughly adjusted to the right position, the hand wheel 29 is turned to drive the adjustment screw 27 to rotate through the worm gear transmission device 28, and the rotation of the adjustment screw 27 can drive the threaded sleeve 43 to move along the axis direction of the adjustment screw 27, thereby driving the adjustment bracket 32 ​​to move through the sliding sleeve 42 and the fixed plate 41, and realizing the fine adjustment of the adjustment bracket 32. Until the top cover 21 is completely horizontal.

[0063] Then the surveying instrument 1 is threadedly mounted on the top surface of the top cover 21, and finally the surveying is performed.

[0064] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
