Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of auxiliary tools for leveling measurement, in particular to a high-precision magnetic leveling measuring ruler pad with a lighting function. Background Technique
[0002] In the surveying and mapping work of large-scale water conservancy and hydropower, roads, railways and other construction projects, high-precision leveling measurement work is required. In conventional leveling measurement work, in addition to necessary observers and rodmen, during the existing leveling measurement, most rodmen adsorb the bottom of the invar rod on the upper surface of the magnetic leveling ruler pad, then set the tip of the steel cone below the ruler pad at the measurement point, and then carry out the measurement work. However, in a darker measurement environment, the rodman cannot accurately place the invar rod at the measurement point and needs other personnel to indicate with a lighting device to accurately place the rod. This measurement method requires 2 auxiliary personnel to complete the entire measurement work; this inevitably causes an increase in some manpower and material resources, reduces work efficiency, increases costs, and also the length of the steel cone below the existing ruler pad is fixed and not convenient to replace. For some measurement points located below the ground surface with small reserved holes, the steel cone below the ruler pad cannot reach the depression point of the measurement point, resulting in the problem that the measurement accuracy cannot be guaranteed. Summary of the Invention
[0003] In view of the deficiencies of the prior art, the utility model provides a high-precision magnetic leveling measuring ruler pad with a lighting function, including a steel cylinder. An upper partition is fixedly connected inside the steel cylinder. A threaded hole A for fixedly connecting a magnet is provided at the center of the upper surface of the partition. The upper surface of the magnet is in the same plane as the upper end surface of the steel cylinder. An annular platform is provided below the inside of the steel cylinder. A bottom plate is connected below the annular platform. A battery is fixedly provided on the upper surface of the bottom plate and inside the steel cylinder. A USB charging port and a plurality of LED lights are provided on the lower surface of the bottom plate. A steel cone is also fixedly connected to the center of the lower surface of the bottom plate.
[0004] Further, a plurality of threaded holes B are provided on the lower surface of the annular platform, and through holes A are provided on the lower surface of the bottom plate at positions corresponding to the threaded holes B.
[0005] Further, a waterproof gasket is provided at the connection between the annular platform and the bottom plate.
[0006] Further, a threaded hole C is provided at the center of the lower bottom surface of the bottom plate. A screw rod head matching the threaded hole C is provided at the upper end of the steel cone, and a conical head is provided at the lower end of the steel cone.
[0007] Further, a through hole B is provided in the middle of the steel cone.
[0008] Further, a switch is also provided on the lower surface of the base plate, and the switch, the USB charging port, the multiple LED lights and the battery are electrically connected.
[0009] The beneficial effects of the present utility model are as follows:
[0010] The combined use of the switch, the USB charging port, the multiple LED lights and the battery can provide illumination in a dark environment, accurately set the ruler, ensure the measurement accuracy. In addition, the base plate and the steel cone are connected by threading. When the measuring point is relatively deep from the ground surface, a longer steel cone can be replaced at any time, so that the tip of the conical head below the steel cone is accurately placed in the depression point of the measuring point, which not only ensures the measurement accuracy, but also saves time and effort.
