Description

Technical Field

[0001] The utility model relates to the technical field of lidar installation, in particular to a mounting frame assembly for a lidar detector. Background Art

[0002] A lidar is a radar system that detects the position, speed and other characteristic quantities of a target by emitting laser beams. Its working principle is to emit a detection signal (laser beam) to the target, and then compare the received signal (target echo) reflected from the target with the emitted signal. After appropriate processing, relevant information of the target can be obtained. Its application range is very wide, especially in the measurement of the volume of trucks. When the truck is moving, the volume of the vehicle can be obtained according to the lidar measurement system.

[0003] When the existing lidar detector measures the volume of a moving truck, generally, the lidar detector is directly installed on the gantry, and then the truck is driven under the gantry to measure its volume. However, after the lidar detector is installed on the gantry, its height is not convenient to adjust, and the installation and disassembly are relatively troublesome. Therefore, further improvement can be made. Content of the Utility Model

[0004] To solve the problems mentioned above, the utility model provides the following technical solution: a mounting frame assembly for a lidar detector, including a base. A sleeve is fixedly installed on the top of the base. A telescopic rod that can be telescoped is slidably inserted into the sleeve. The top of the telescopic rod is fixedly installed with a top plate. An installation shell assembly is arranged on the bottom side of the top plate. A detector body is installed in the installation shell assembly. The installation shell assembly facilitates the installation and disassembly of the detector body. By pulling the telescopic rod, the height of the detector body can be adjusted, improving the practicability of lidar detection.

[0005] As an optimization, a chute is formed on the surface of the sleeve. A plurality of card slots perpendicular to the chute are also formed on the surface of the sleeve, and the card slots communicate with the chute. A spring pin is arranged in the bottom wall of the card slot. A support rod is fixedly installed at the bottom of the telescopic rod. The support rod is slidably connected in the chute. By pushing and pulling the support rod to slide along the inner wall of the chute, the height of the telescopic rod can be adjusted. Then, the support rod is turned into the card slot to position the adjusted telescopic rod. The spring pin can hold the support rod to prevent it from sliding out, improving the stability.

[0006] As an optimization, the inner diameters of the chute and the card slot are the same, and the outer diameter of the support rod is the same as the inner diameters of the chute and the card slot.

[0007] As an optimization, the mounting shell assembly includes a fixing plate fixedly mounted on the bottom side of the top plate, a screw is rotatably connected to the middle part of the bottom side of the fixing plate, a threaded sleeve is spirally sleeved on the outer side of the screw, support plates are fixedly mounted on both sides of the threaded sleeve, a guide rod is fixedly mounted on the top side of the support plate, the guide rod is slidably inserted into the two sides of the fixing plate, and the threaded sleeve is guided and limited by the guide rod, and then the screw is turned clockwise inside the threaded sleeve, which will drive the threaded sleeve to move upward.

[0008] As an optimization, a bottom plate is fixedly installed on the bottom of the threaded sleeve, a ring is fixedly installed on the top side of the bottom plate, and a top cover is fixedly installed on the bottom side of the top plate and directly above the ring. The detector body is embedded in the ring, and the upward movement of the bottom plate will drive the detector body to be embedded upward in the top cover, so that the detector body can be stably installed between the ring and the top cover, thereby facilitating installation and disassembly.

[0009] As an optimization, gaskets are installed inside the ring and the top cover, and the gaskets are wrapped around the outside of the detector body. The gaskets are in close contact with the detector body to protect the detector body.

[0010] As an optimization, the outer diameter of the top cover is larger than the outer diameter of the ring, and the top cover is in a truncated cone shape, which can provide sunshade and rain protection.

[0011] The beneficial effects of the present invention are as follows: the mounting bracket assembly of the laser radar detector can drive the telescopic rod to move upward from the inside of the sleeve by turning the support rod from the card slot into the slide slot, and then pulling the support rod upward, which will cause the detector body located at the top of the telescopic rod to move upward synchronously, and then the support rod is turned again to move into the card slot, and the spring pin will limit the support rod from accidentally sliding out, so that the height of the laser radar detector can be adjusted according to actual conditions, thereby improving its practicality; the mounting bracket assembly of the laser radar detector can drive the threaded sleeve to move upward by turning the screw clockwise to rotate inside the threaded sleeve, so it will drive the bottom plate to move upward, so that the detector body is embedded upward into the top cover, and then the detector body can be installed. Similarly, turning the screw in the opposite direction can drive the bottom plate to move downward, and then the detector body can be easily taken out, thereby facilitating the installation and disassembly of the laser radar detector.
