Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage electrical appliance box measurement, in particular to a measuring device for high-voltage electrical appliances. Background Art

[0002] The high-voltage electrical box of a high-speed train or a motor vehicle is a large box used to install high-voltage electrical components. It is approximately 2100x1600x500 (mm) in length, width and height. It has a large internal space, and the installed electrical components and mounting seats are closely related in size to each other. If there is a slight deviation in the manufacturing of the box or the measurement is inaccurate, it will be impossible to install it directly, or there will be interference after installation. Long-term bumpy conditions will cause the electrical components to deform and fail, posing a safety hazard to the operation of the locomotive.

[0003] Among the many electrical components installed in the high-voltage electrical box, there is a group of electrical components called vacuum circuit breakers, which are composed of two major parts: the "main disconnect switch" and the "main circuit breaker". The main disconnect switch is installed on the mounting seat at the bottom of the box body, and the main circuit breaker is installed on the mounting seat inside the box body. A space structure is formed between the two sets of mounting seats. After the box body is completed, it is extremely inconvenient to obtain correct measurement data.

[0004] For a long time, the dimensional connection between the two sets of mounting bases has been guaranteed by the assembly tooling during welding. No precise measurement is performed after welding, or only simple measurement is performed. The method adopted in the measurement process is that multiple rods and multiple people work together. This measurement method is relatively backward, and has the disadvantages of too many operators, low efficiency, and inaccurate measurement. It not only brings inconvenience to the installation of electrical components, but also poses a safety hazard to the operation of the locomotive. Utility Model Content

[0005] In view of the above problems, the utility model provides a measuring device for high-voltage electrical appliances, which reduces the number of personnel for measuring operations, improves measuring efficiency, and improves measuring accuracy.

[0006] To achieve the above-mentioned purpose, the technical solution of the utility model is: a measuring device for a high-voltage electrical box, comprising a support rod, an adjusting rod being vertically connected to the support rod, a notch being provided on the adjusting rod, a bidirectional lead screw being provided inside the adjusting rod, a rotating bearing being provided at one end of the bidirectional lead screw, and an adjusting rod being extended out of the other end and connected to a driving turntable, a nut being provided on the bidirectional lead screw, a connecting block being fixedly connected to the nut, the connecting block extending out of the notch and being detachably connected to a detection plate.

[0007] As a further solution of the utility model: a limiting groove is provided on the support rod, a threaded hole is provided on the back of the adjusting rod, the threaded rod passes through the limiting groove and is screwed together with the threaded hole, a rubber base is provided on the end of the threaded rod extending out of the limiting groove, a limiting block is fixedly connected to the back of the adjusting rod, and the limiting block is in contact with the support rod.

[0008] As a further solution of the utility model: a connecting rod is inserted into the support rod, through holes are formed on the support rod and the connecting rod, and a fixing rod is inserted into the through hole.

[0009] As a further solution of the utility model: scales are provided on both sides of the notch.

[0010] As a further solution of the utility model: the driving turntable is connected to the servo motor via a rotating shaft.

[0011] As a further solution of the present invention: the detection plate is in a right-angle shape.

[0012] As a further solution of the utility model: a suction cup base is inserted into the bottom of the connecting rod, and a pressing rod is provided on the suction cup base.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model drives the rotation of the bidirectional screw by driving the turntable, thereby driving the movement of the detection plate, so that the detection plate is close to the measured box, and then by loosening the rubber base, the adjustment rod can slide up and down in the limit groove of the support rod, and the setting of the limit block reduces the offset of the adjustment rod when sliding, and at the same time completes the measurement of the spacing in the box and the deviation of the upper and lower sides of the box, reducing the measurement error. During the detection process, if it is found that the gap is uneven or the size deviation of the upper and lower sides of the measured box is large, or even there is a jamming phenomenon when sliding up and down, the mounting seat needs to be repaired until the detection requirements are met, which can effectively avoid the phenomenon of being unable to install or installing interference in the later stage. A similar method is also used to solve the spatial installation size problem of other electrical components, providing a higher insurance factor for the effective operation of electrical components and providing a reliable technical guarantee for the safe operation of locomotives; at the same time, the utility model reduces the number of required detection personnel and improves the efficiency of detection.
