Description

Technical Field

[0001] This utility model relates to the field of measurement tools, specifically a measurement tool for land planning surveys. Background Technology

[0002] RTK (Real-Time Kinematic) surveying instruments are tools used for land planning and surveying. They can accurately determine the coordinates of land boundary points, perform topographic surveying, and also be used for engineering layout. RTK surveying instruments come in two types: base station type and mobile type. In land planning and surveying engineering, base station type RTK surveying instruments are mainly used to establish benchmark stations, providing reference data for the entire survey area. They are typically set up at points with known precise coordinates. Mobile RTK surveying instruments are used for real-time dynamic measurements within the survey area. Surveyors can carry the mobile station to different locations. For example, in land boundary surveying, it can move along the boundary to obtain the precise coordinates of various boundary points; in topographic surveying, it can measure at different topographic feature points to quickly obtain topographic data.

[0003] When used together, these two devices can function as a fixed base station at a known point or as a mobile station for measurement. Existing base stations are bulky and not convenient or flexible enough. Therefore, to achieve integrated design, flexibly adjust the operating mode according to the user's actual needs, and improve the convenience and flexibility of RTK measurement instruments, we provide a land planning surveying tool. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a land planning surveying and measurement tool, comprising a support rod and an RTK antenna device and an RTK measurement device integrated and mounted on the support rod. A support frame is detachably mounted on the support rod. The support frame includes a mounting base, a fixed leg, and a movable leg. The mounting base is fitted onto the support rod and locked onto the support rod by locking bolts, and is detachably fixed. The fixed leg is fixed to the bottom of the mounting base along the length of the support rod. The upper end of the movable leg is dampedly hinged to the upper end of the fixed leg. The movable leg can rotate and unfold around the hinged end around the fixed leg. A caster wheel is fixedly mounted on the lower end of the movable leg.

[0006] Preferably, the support rod is a carbon fiber rod.

[0007] Preferably, the support rod is composed of three sections: upper, middle, and lower.

[0008] Preferably, the upper section of the support rod is a telescopic rod, and the telescopic rod of the upper section is provided with laser-marked scale lines. The upper and lower sections of the support rod are provided with bolt heads at opposite ends. The middle section of the support rod is provided with threaded holes at both ends that match the bolt heads. The middle section of the support rod has radially protruding thickened portions at the connection positions at both ends, and the outer diameter of the two ends of the middle section is 10-50% larger than the outer diameter of the middle part of the middle section.

[0009] Preferably, the support frame is detachably mounted on the lower section of the support rod, and the inner wall of the mounting base is provided with a spring plunger with a ball head protruding from the inner wall of the mounting base in a radial direction. The lower section of the support rod is provided with a vertical slide rail, and the ball head end of the spring plunger is slidably positioned and limited within the slide rail.

[0010] Preferably, there are at least three sets of fixed legs and movable legs.

[0011] This utility model has the following beneficial effects:

[0012] This utility model features a support frame installed on a support rod, with casters installed on the support frame. The support frame is easy to install and can be disassembled according to the user's actual needs. When both base station mode and mobile mode are required, the support frame can be unfolded and fixed according to the base station mode requirements, and the support frame can be folded up according to the mobile mode requirements. After being folded up, it is small in size and does not take up much space, and the working mode can be flexibly adjusted.

[0013] The support frame can be unfolded to allow the measuring instrument to stand upright, making it easy for the measuring personnel to detach their hands from the rod and placing the measuring instrument anywhere for greater convenience. When folded, the support frame can be fixed above the toes of the support rod without obstructing the measurement, or fixed below the toes of the support rod and made in contact with the ground via casters, making it easier for the measuring personnel to carry the measuring instrument with less effort and making it convenient to use.
