Description

A positioning benchmark for national land space planning

Technical Field

The utility model relates to the technical field of land surveying equipment, in particular to a national land space planning positioning benchmark.

Background technique

Land surveying is the work of measuring and mapping the quantity, distribution and topography of various types of land using surveying and remote sensing technology. It includes topographic surveying, cadastral surveying, land leveling surveying, current land use surveying, and investigation of reserve resources such as barren hills and wastelands. The surveying methods used include geodetic surveying, ordinary surveying, aerial photogrammetry, remote sensing technology and map compilation. With the gradual completion of the national basic topographic map, land surveying mainly refers to various contents other than topographic surveying, and all of them are measured based on the national basic topographic map.

According to the Chinese patent application number 202220474060.7, a positioning pole for land surveying is proposed, which allows workers to observe whether the positioning pole is vertical in time, so as to facilitate adjustment and reduce the occurrence of errors. At the same time, the screw is driven to rotate by the torsion plate, so that the fixed sleeve can be driven to move up and down, and the angles of the connecting rod and the support rod can be deflected, so that the positioning pole can be supported, which is convenient for stable placement and better measurement. The problem that the current positioning pole cannot observe the verticality of the positioning pole and cannot provide stable support is solved.

However, after improvements, the device still has the problem of not being able to maintain stability on uneven roads. Since the length of the device's support rod is fixed, when encountering bumpy ground, the bottom of the support leg will not touch the ground. At this time, the device will have an unstable center of gravity and is prone to shaking or even tipping over. For this reason, we propose a national land space planning positioning benchmark.

The fixed plate 1 is rotatably connected to the support leg 4 through the connecting frame 11, and the inner part of the support leg 4 is slidably connected to the plug rod 41, and a mounting plate 5 is fixedly installed on one side of the support leg 4, and the inner part of the mounting plate 5 is rotatably connected to the rotating shaft 1 51, and a full gear 52 is fixedly installed inside the mounting plate 5 and on the outer side of the rotating shaft 1 51, and a rack 42 is fixedly installed on one side of the plug rod 41, and the full gear 52 is meshed with the rack 42, and a ratchet 53 is fixedly installed inside the mounting plate 5 and on the outer side of the rotating shaft 1 51. The mounting plate 5 is internally rotatably connected with a pawl 54, which is meshed with a ratchet 53. One end of the shaft 51 is located on the outside of the mounting plate 5 and is fixedly connected to one side of the handwheel 6. When the staff selects a measuring position and needs to measure, the handwheel 6 at one end of the shaft 51 is rotated clockwise, thereby driving the full gear 52 to rotate. The full gear 52 is meshed with the rack 42, so that the insertion rod 41 moves downward until the tip of the bottom is inserted into the ground, thereby fixing the device. The length of the insertion rod 41 is adjusted by rotating the handwheel 6, so that the device remains stable when encountering an uneven ground, thereby improving the limitations of the device. At the same time, through the cooperation of the pawl 54 and the ratchet 53, the insertion rod 41 can only move downward, preventing the insertion rod 41 from retracting upward when it contacts the ground, thereby improving the practicability of the device.

The pole body 2 includes a sleeve rod 21, the bottom of which is fixedly connected to the top of the fixed plate 1, and a telescopic rod 22 is slidably connected inside the sleeve rod 21. A threaded rod 23 is rotatably connected to the top of the fixed plate 1 and located inside the sleeve rod 21. The threaded rod 23 is threadedly connected to the telescopic rod 22. One side of the sleeve rod 21 is rotatably connected to a second rotating shaft 24. A bevel gear 25 is fixedly installed on the outer side of the threaded rod 23 and one end of the second rotating shaft 24. The two bevel gears 25 are meshingly connected. One end of the second rotating shaft 24 is located on the outer side of the sleeve rod 21 and is fixedly connected to one side of a hand wheel 6. The hand wheel 6 at one end of the second rotating shaft 24 is rotated, and the second rotating shaft 24 drives the bevel gear 25 at the other end to rotate.

When the device is supported, the pawl 54 is pushed to engage with the ratchet 53 by the elastic force of the spring 56, so that the insertion rod 41 can only move downward, preventing the insertion rod 41 from moving upward during support. When the insertion rod 41 needs to be retracted, the driving rod 57 on one side is moved to drive the pawl 54 to rotate so that it no longer engages with the ratchet 53, so that the hand wheel 6 can be turned counterclockwise to retract the insertion rod 41 into the supporting leg 4, In order to improve the practicality of the device, a plurality of limit blocks 26 are fixedly installed on the outer side of the telescopic rod 22, and a plurality of slide grooves 27 are opened inside the sleeve rod 21.
