Description

Technical Field

[0001] This utility model relates to the field of surveying and mapping technology, and in particular to a surveying and mapping structure and engineering surveying equipment. Background Technology

[0002] Surveying and mapping, literally understood as measurement and drawing, is based on computer technology, optoelectronic technology, network communication technology, space science, and information science. It uses Global Navigation Satellite System (GNSS), Remote Sensing (RS), and Geographic Information System (GIS) as its core technologies. It selects existing feature points and boundaries on the ground and obtains graphics and locations reflecting the current state of the ground and related information through measurement methods for use in engineering construction, planning and design, and administrative management.

[0003] The patent with authorization announcement number CN219602962U describes a line laying structure and engineering surveying equipment. The line laying structure includes a cover. The line laying structure proposed in this utility model drives the rotation of the rotating bracket by rotating the rod in both directions, so that the surveying line contacts the ink block when it is pulled out and contacts the cleaning block when it is retracted. This ensures that the surveying line is already stained with ink when it is pulled out and is clean when it is retracted. The cover and the bottom shell are connected by a locking mechanism and a slot, allowing the whole structure to be opened for easy maintenance and cleaning of the cleaning block.

[0004] However, the above patents still have the following problems: When cleaning the toner on the surface of the surveying line, the cleaned toner falls to the inside of the bottom shell, requiring the staff to clean the toner on the inside of the bottom shell a second time, which is inconvenient for the staff to use. At the same time, the surveying line is coated with toner by passing through the ink block. Since the ink block cannot make the toner gather around the surveying line, as the powder around the surveying line gradually decreases, it will lead to uneven powder coating on the surveying line. Therefore, in order to solve the above problems, a line laying structure and engineering surveying equipment are proposed. Utility Model Content

[0025] Example

[0026] like Figure 1-4 As shown, a line-laying structure and engineering surveying equipment includes a support shell 1 and a drum 3. The drum 3 is rotatably connected to the inner side of the support shell 1. A handwheel 21 is fixedly connected to one end of the drum 3. A surveying line 4 is wound onto the outer side of the drum 3. A stop ball 5 is fixedly connected to the other end of the surveying line 4. A toner cartridge 6 is fixedly connected to the inner side of the support shell 1. A toner roller 7 with a concave design in the middle is rotatably connected to the inner side of the toner cartridge 6. Toner brushes 8 are fixedly connected to the inner wall of the concave part of the toner roller 7. A pressing mechanism is provided above the support shell 1, a cleaning mechanism is provided at one end of the support shell 1, and a discharge port 2 is provided on the inner side of one end of the support shell 1. A guide ring 9 is fixedly connected to one end of the toner cartridge 6. The guide ring 9 can ensure that the mapping line 4 is always in the middle position of the toner cartridge 6, ensuring normal feeding of the mapping line 6. When the toner roller 7 rotates with the toner bristles 8, toner will adhere to the surface of the toner bristles 8, and the toner bristles 8 will carry the toner to the surface of the mapping line 4, ensuring that the mapping line 4 is evenly coated with toner. The material of the toner bristles 8 is nylon.

[0027] As a further improvement to this utility model, such as Figure 1 and Figure 2 As shown, the pressing mechanism includes a guide post 10 slidably connected to the support shell 1. A connecting frame 11 is fixedly connected to the bottom end of the guide post 10. A pressure roller 12 is rotatably connected to the inner side of the connecting frame 11. The pressure roller 12 is positioned above the recess of the toner roller 7. When ink needs to be applied to the survey line 4, the pressure roller 12 presses against the survey line 4. When the survey line 4 is pulled, the survey line 4 will also rotate with the toner roller 7, thereby ensuring that the toner roller 7 carries the toner from the bottom of the toner cartridge 6 upward through the toner bristles 8, ensuring the uniformity of the toner application on the survey line 4.

[0028] As a further improvement to this utility model, such as Figure 1 and Figure 2As shown, the pressing mechanism also includes a fixing plate 13 fixedly connected to the support shell 1. A locking screw 14 is spirally connected to the inner side of one end of the fixing plate 13, and the locking screw 14 is in contact with the guide post 10. The guide post 10 can slide along the fixing plate 13. When the guide post 10 moves to a suitable position, the locking screw 14 can realize the limiting and fixing between the guide post 10 and the fixing plate 13.

[0029] As a further improvement to this utility model, such as Figure 2 and Figure 4 As shown, the cleaning mechanism includes a connecting cover 15 fixedly connected to the support shell 1. A screw 16 is rotatably connected to the inner side of the connecting cover 15. Connecting posts 17 are spirally connected to both sides of the vertical center line of the screw 16. A cleaning plate 18 is fixedly connected to the bottom end of the connecting post 17. A cleaning bristle 19 is fixedly connected to one end of the cleaning plate 18. The cleaning bristle 19 is made of nylon. The cleaning bristle 19 can clean the residual toner on the surface of the surveying line 4 and the dirt and other impurities adhering to the surface of the surveying line 4.

[0030] As a further improvement to this utility model, such as Figure 4 As shown, the threads on both sides of the vertical center line of the screw 16 are arranged in opposite directions to ensure that the connecting posts 17 on both sides can move in opposite directions at the same time.

[0031] As a further improvement to this utility model, such as Figure 2 As shown, a guide plate 20 is provided below the cleaning plate 18. The guide plate 20 is fixedly connected to the support shell 1 and is located on one side of the discharge port 2. The toner 4 and dirt and other impurities that are cleaned will slide out from the inside of the support shell 1 along the guide plate 20, ensuring that the toner and dirt and other impurities will not fall into the inside of the support shell 1, so that the staff does not need to clean them again, which is convenient for the staff to use.

[0032] As a further improvement of this utility model, an engineering surveying and mapping device includes a line-laying structure.

[0033] Workflow: When the survey line 4 needs to be pulled out from the inside of the support shell 1, first rotate the screw 16, so that the screw 16 moves the corresponding cleaning plate 18 and cleaning bristles 19 away from each other through the connecting column 17, ensuring that the survey line 4 does not touch the cleaning bristles 19. Then, the guide column 10 moves the pressure roller 12 into the recess of the toner roller 7 through the connecting frame 11, and at the same time, the pressure roller 12 presses the survey line 4. Then, the locking screw 14 is used to limit and fix the guide column 10 and the fixing plate 13. Then, the operator can pull the survey line 4 through the ball stop 5. When the survey line 4 moves, the survey line 4 will also rotate with the toner roller 7, so that the toner roller 7 carries the toner at the bottom of the toner cartridge 6 upward through the toner bristles 8. 8. The toner is carried to the surface of the survey line 4, thus ensuring the uniformity of the toner on the survey line 4. When the survey line 4 needs to be retracted, the pressure roller 12 stops pressing on the survey line 4. At the same time, the cleaning plate 18 with the cleaning bristles 19 clamps the survey line 4. When the drum 3 rewinds the survey line 4, the survey line 4 between the drum 3 and the cleaning plate 18 is in a taut state, thus ensuring that the survey line 4 does not come into contact with the toner bristles 8. At the same time, the cleaning bristles 19 can clean the residual toner and dirt and other impurities on the surface of the survey line 4. The cleaned toner 4 and dirt and other impurities will slide out from the inside of the support shell 1 along the guide plate 20, ensuring that the toner and dirt and other impurities do not fall into the inside of the support shell 1. No secondary cleaning is required by the staff, making it convenient for the staff to use.
