However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] like Figure 1-Figure 7A vertical surveying and mapping device for construction engineering surveying and mapping that is easy to fix quickly is shown, comprising a surveying and mapping instrument 1, a fixing plate 2 is fixedly arranged at the bottom of the surveying and mapping instrument 1, a positioning cylinder 3 is arranged at the bottom of the fixing plate 2, a positioning frame box 6 is arranged below the surveying and mapping instrument 1, a base plate 4 is fixedly arranged at the bottom of the positioning frame box 6, a bracket 5 is installed at the bottom of the base plate 4, a first layer 8, a second layer 9, and a third layer 10 are sequentially opened inside the positioning frame box 6 from top to bottom, a clamping mechanism 13 is arranged inside the first layer 8, a through hole is opened between the first layer 8 and the second layer 9, and the through hole is located at the center of the first layer 8 and the second layer 9, a gear 20 is rotatably installed inside the through hole, the upper part of the gear 20 is located in the first layer 8, and the lower part of the gear 20 is located in the lower part of the gear 20. In the second layer 9, locking mechanisms 21 are provided at both ends of the top of the positioning frame box 6, a cylinder 11 is installed inside the third layer 10, an opening 32 is provided at the end of the third layer 10, and a push plate 12 is provided at the output end of the cylinder 11. The push plate 12 is located on the outside of the positioning frame box 6. With the cooperation of the cylinder 11, the clamping mechanism 13 and the locking mechanism 21, the three columns 16 can center and clamp the positioning cylinder 3, and can quickly move the positioning cylinder 3 to the center of the clamping groove 7. At the same time, the end of the locking block 28 can be pressed on the outer surface of the locking plate 2, so that the surveying instrument 1 can be quickly centered and fixed at the center of the top of the base plate 4. The installation is convenient and quick, and no manual alignment and fixation are required, thereby improving the installation efficiency of the surveying instrument 1.

[0025] The clamping mechanism 13 includes three turntables 14, which are evenly arranged on the sides of the gear 20. The surfaces of the three turntables 14 are all provided with arc-shaped racks 15, which mesh with the gear 20. A protruding bar is protruded from the surface of the turntable 14, and a column 16 is installed on the top of the other end of the protruding bar. Since the arc-shaped rack 15 meshes with the gear 20, when the gear 20 rotates forward, the three turntables 14 rotate in the opposite direction. At this time, the protruding bar can gradually approach the center of the positioning frame box 6, so that the three columns 16 can center the positioning cylinder 3 and can quickly move the positioning cylinder 3 to the center of the clamping groove 7. When the gear 20 rotates reversely, the three turntables 14 rotate in the opposite direction. At this time, the protruding bar can gradually move to the outside of the positioning frame box 6, so that the three columns 16 gradually move away from the positioning cylinder 3, making it very convenient for the staff to disassemble and assemble the surveying instrument 1, thereby improving the assembly efficiency of the surveying instrument 1.

[0026] A pushing column 18 is provided in the second layer 9 and on one side of the gear 20. A linear rack 19 is provided on the surface of the pushing column 18. The linear rack 19 meshes with the gear 20. The end of the pushing column 18 is connected to the push plate 12. The cylinder 11 drives the pushing column 18 to move through the push plate 12, and the linear rack 19 on the surface of the pushing column 18 drives the gear 20 to rotate, so as to realize the control of the clamping mechanism 13.

[0027] A snap-in groove 7 is provided on the top of the positioning frame box 6, and a slide groove 17 is provided on the surface of the snap-in groove 7. The column 16 passes through the slide groove 17, and the positioning cylinder 3 can be directly inserted into the snap-in groove 7. When the clamping mechanism 13 is working, the column 16 can slide inside the slide groove 17 to center the positioning cylinder 3, so that the surveying instrument 1 can be quickly positioned at the center of the positioning frame box 6.

[0028] The locking mechanism 21 includes a locking block 28, one end of which is clamped on the top of the locking plate 2, and the other end of the locking block 28 is installed with a guide rod 24 through a rotating shaft. The surface of the guide rod 24 is inserted into the positioning frame box 6, and a roller 25 is arranged at the bottom of the guide rod 24. A slide bar 31 is fixedly arranged inside the second layer 9, and a push block 22 is slidably installed on the surface of the slide bar 31. The end of the push block 22 away from the push plate 12 is set as an arc surface, and the upper surface of the positioning frame box 6 and on both sides of the locking block 28 are fixedly arranged There are side strips 26, and the middle ends of the side strips 26 and the locking block 28 are connected by a connecting rod 27 through a rotating shaft. When the push block 22 moves toward the depth of the second layer 9, the arc surface at the end of the push block 22 has an extrusion effect on the roller 25, so that the roller 25 drives the guide rod 24 to move upward as a whole. At the same time, the top of the guide rod 24 has an upward extrusion effect on the locking block 28. Under the action of the connecting rod 27, the other end of the locking block 28 can be pressed on the outer surface of the locking plate 2, thereby fixing the position of the locking plate 2.

[0029] A push rod 23 is fixedly provided on the surface of the push plate 12, and the push rod 23 is movably installed in the second layer 9. The other end of the push rod 23 is fixedly connected to the push block 22. The cylinder 11 drives the push rod 23 to move through the push plate 12, and the push rod 23 can control the push block 22 to move in the second layer 9, so as to realize the control of the locking mechanism 21.

[0030] A limit plate 29 is fixedly provided in the middle of the guide rod 24, and a spring 30 is provided on the surface of the guide rod 24 and above the limit plate 29. The spring 30 and the limit plate 29 are both located in the first layer 8. When the push block 22 is away from the roller 25, under the action of the elastic force of the spring 30, the elastic force can push the limit plate 29 downward as a whole. At this time, the top of the guide rod 24 has the effect of pulling the locking block 28 downward. Under the action of the connecting rod 27, the other end of the locking block 28 is tilted, which is convenient for the staff to disassemble and assemble the surveying instrument 1.

[0031] Working principle: First, the staff directly inserts the positioning cylinder 3 at the bottom of the locking plate 2 into the clamping groove 7, and then the cylinder 11 drives the push column 18 to move through the push plate 12. When the push plate 12 gradually moves toward the opening 32, the linear rack 19 on the surface of the push column 18 drives the gear 20 to rotate forward. At this time, the three turntables 14 all rotate in the opposite direction, and the extended strips can gradually move toward the center of the positioning frame box 6. The three columns 16 can center the positioning cylinder 3 and quickly move the positioning cylinder 3 to the center of the clamping groove 7, so that the surveying instrument 1 can be quickly aligned with the base plate 4. Then, while the clamping mechanism 13 is running, the push plate 12 will also drive the push rod 23 to move, and the push rod 23 can be pushed. The rod 23 can push the push block 22 in the second layer 9, so that the push block 22 can gradually move to the depth of the second layer 9. The arc surface at the end of the push block 22 has an extrusion effect on the roller 25, so that the roller 25 drives the guide rod 24 to move upward as a whole. At the same time, the top of the guide rod 24 has an upward extrusion effect on the locking block 28. Under the action of the connecting rod 27, the other end of the locking block 28 can be pressed on the outer surface of the locking disk 2, thereby achieving the fixation of the position of the locking disk 2. With the cooperation of the cylinder 11, the clamping mechanism 13 and the locking mechanism 21, the surveying instrument 1 can be quickly centered at the center of the top of the base plate 4. The installation is convenient and quick, and no manual alignment and fixation are required, thereby improving the installation efficiency of the surveying instrument 1.
