Description

Technical Field

[0001] This utility model relates to testing equipment, and more particularly to a speed and direction testing equipment. Background Technology

[0002] Currently, commonly used speed measurement devices include flash velocimeters and infrared velocimeters. However, neither of these mainstream devices has a direction detection function, their functions are relatively limited, and their adaptability is poor. With the development of industrial automation, the monitoring requirements for rotating equipment are becoming increasingly stringent. It is necessary not only to know its speed but also to determine its rotation direction (such as determining the forward and reverse rotation of fans and pumps). Therefore, improvements are needed. Summary of the Invention

[0003] This invention addresses the shortcomings of existing detection equipment, such as limited functionality and poor adaptability, by providing a new type of speed and steering detection device.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] A speed and steering detection device includes a detection device equipped with a laser emitting device and a laser receiving device, and also includes an adapter adapted to the device under test. The adapter has a barcode area, which is composed of alternating high-reflectivity areas and low-reflectivity areas. The laser emitting device and the laser receiving device are respectively used to send signals to the barcode area and receive signals to the barcode area, thereby obtaining the speed and steering data of the device under test.

[0006] This application adopts a signal interaction method between a laser emitting device and a laser receiving device. Combined with the high-reflection area and low-reflection area alternately set in the barcode area of ​​the adapter, the laser signal feedback difference is obvious, which can accurately capture the motion characteristics of the device under test and realize the efficient acquisition of speed and direction data. The design of the adapter to adapt to the device under test breaks the limitation of adapting to a single device under test and improves the versatility of the device under test.

[0007] Preferably, the aforementioned speed and steering detection device includes a housing, in which a laser emitting device and a laser receiving device are integrated. A through hole is provided at the front end of the housing, and the laser emitting device and the laser receiving device cooperate with the through hole. A display screen for displaying the detection results is provided at the upper end of the housing.

[0008] The housing forms a closed protective structure for the laser emitting device and the laser receiving device, effectively preventing damage to the core detection components from external dust and collisions, extending the service life of the equipment, and making the overall structure more compact, easy to carry and operate.

[0009] Preferably, in the aforementioned speed and direction detection device, the adapter includes, from top to bottom, a connecting end, a cylindrical area, and a fixing area. A rectangular groove is uniformly formed along the circumferential direction on the cylindrical area. The barcode area is composed of the rectangular groove and an ungrooved substrate area. The through hole mates with the cylindrical area.

[0010] The adapter adopts a three-section structure of "connection end - cylindrical area - fixed area". The connection end facilitates quick docking with the device to be tested, the fixed area ensures connection stability, and the cylindrical area serves as the carrier of the barcode area. The structural design meets the stress and signal transmission requirements during the testing process.

[0011] Preferably, in the aforementioned speed and steering detection device, the fixing area includes a fixing block and a tensioning block. The fixing area has mounting holes that penetrate the fixing block and the tensioning block in a horizontal direction. The fixing block and the tensioning block are fixed together by bolts.

[0012] The fixing area uses a combination of fixing blocks, tightening blocks and bolts. By adjusting the tightness of the bolts, the clamping diameter of the mounting holes can be changed, adapting to the connection parts of equipment to be tested of different sizes, thus solving the problem of limited adaptability of traditional fixing structures.

[0013] Preferably, in the aforementioned speed and steering detection device, a circuit board is also provided inside the housing, on which a high-frequency laser sensor, a buffer module, and a timing module are integrated.

[0014] Preferably, in the aforementioned speed and direction detection device, the adapter is provided with a connecting hole that runs longitudinally through the connecting end, the cylindrical area, and the fixed area.

[0015] The present invention has the following advantages through the above structural improvements:

[0016] Compared with existing testing equipment, this application has the advantages of diverse testing functions and strong adaptability. In particular, by using the laser emitting device, the laser receiving device, and the adapter in cooperation, the testing equipment can detect both the normal rotation speed and the direction of rotation of the equipment under test. Furthermore, the three-section structure, adjustable fixing area, and connection hole design of the adapter can accommodate different types and sizes of equipment under test, thus improving the adaptability of the testing equipment.

[0036] Specifically, the bolt fixing method ensures that the adapter 2 is firmly connected to the device under test, avoiding loosening due to vibration and rotation during the test, ensuring the relative position stability of the barcode area 3 with the laser emitting device 11 and the laser receiving device 12, reducing test errors, and at the same time, it is convenient to install and disassemble, improving test efficiency.

[0037] Preferably, the housing 13 is further provided with a circuit board 133, on which a high-frequency laser sensor 4, a buffer module 5 and a timing module 6 are integrated.
