Radar speed measurement equipment with debugging mechanism easy to assemble and disassemble

Abstract

The invention relates to the technical field of radar speed measurement auxiliary installation, in particular to radar speed measurement equipment with a debugging mechanism easy to assemble and disassemble. The radar speed measurement equipment comprises a longitudinal fixed rod, a transverse fixed rod and shooting equipment for radar speed measurement, wherein the bottom of longitudinal fixed rod is fixedly arranged at one side of a road, the transverse fixed rod is welded and fixed onto a side surface of the top of the longitudinal fixed rod, and a bottom assembly groove is formed in a right side of a lower surface of the transverse fixed rod. In the radar speed measurement equipment with the debugging mechanism easy to assemble and disassemble, a bottom lifting seat is controlled to ascend and descend and a top external threaded adjustment lead screw is controlled to rotate respectively by a first longitudinal lifting lead screw and a second longitudinal lifting lead screw, so thatthe shooting equipment for radar speed measurement movably connected to a translation opening in the bottom of a lower end of the transverse fixed rod is controlled to translate, ascend and descend,the assembly, disassembly and adjustment of the shooting equipment for radar speed measurement does not dependent on large-size lifting equipment and can be completed only by a worker to operate at the bottom, the construction operation is simple and convenient, the construction period is short, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of radar speed measurement auxiliary installation, in particular to a radar speed measurement device with an easy-to-assemble and disassemble debugging mechanism. Background technique [0002] Radar speed measurement mainly uses the principle of the Doppler effect: when the target approaches the radar antenna, the frequency of the reflected signal will be higher than the frequency of the transmitter; conversely, when the target moves away from the antenna, the frequency of the reflected signal will be lower than the frequency of the transmitted signal. machine frequency. In this way, the relative speed between the target and the radar can be calculated by changing the value of the frequency (the Doppler frequency is positive when the target is flying against the radar, and the Doppler frequency is negative when the target is flying away from the radar). It has been widely used in police speed testing and ot...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: in order to solve the problems existing in the above-mentioned background technology, provide an improved radar speed measuring device with an easy-to-assemble and disassemble debugging mechanism, and solve the problem that most of the installation mechanisms of current radar speed measuring devices have simple and fixed structures and a single assembly method , and once the installation is completed, it cannot be adjusted at a low position, resulting in the problem that the early installation and later maintenance and replacement often require the auxiliary use of large-scale equipment, the construction period is long, and the cost is high
