Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of measuring device, concretely relates to a mobile guide column automatic measuring trolley of vehicle bogie. BACKGROUND

[0002] The vehicle bogie is one of the most important components in the structure of the rail vehicle, which is connected into a group by two pairs or more than two pairs of wheel pairs on the vehicle through the frame and other devices, and can rotate relative to the vehicle body, and is equipped with a spring and other components to form an independent running structure.

[0003] In the assembly process of the rail transit vehicle bogie, the accurate measurement of the center distance of the guide column is crucial to ensure the running speed and stability of the vehicle. At present, the method of measuring by manual use of the caliper has certain limitations, including large measurement error and low efficiency, due to the large spacing between the guide columns. In order to solve these problems, it is particularly important to develop an automatic measuring device for quickly and accurately measuring the spacing between the guide columns of the bogie. UTILITY MODEL CONTENTS

[0004] In view of the problems of large measurement error of the center distance of the guide column of the bogie and time-consuming and laborious manual measurement, the utility model provides a mobile guide column automatic measuring trolley of vehicle bogie.

[0005] A mobile guide column automatic measuring trolley of vehicle bogie, comprising: a measuring device and a mobile trolley, the trolley body is a cuboid, and walking wheels are arranged below the trolley body, the measuring device is provided with a measuring head, and the trolley body is connected with the measuring device at the upper end surface and keeps the measuring head extending outward from the trolley body.

[0006] Further, the measuring device further comprises a lower sliding table, a connecting plate and an upper sliding table, the lower sliding table is connected to the upper end surface of the mobile trolley, one end of the connecting plate is connected with the lower sliding table through a sliding table body, the other end is connected with the upper sliding table, the measuring head is connected with the upper sliding table through the sliding table body, the connecting plate can slide relative to the lower sliding table, and the measuring head can slide relative to the upper sliding table.

[0007] Further, the measuring device is four, and is arranged at four corners of the trolley body respectively.

[0008] The mobile trolley moves at a fixed point on the track. DRAWING DESCRIPTION
