The invention discloses a device for measuring a static contact force of a current collector of an electric locomotive, and the device comprises an upper support (8), a lower support (9), and a mobile supporting platform (6). The mobile supporting platform (6) is disposed between the upper support (8) and the lower support (9). A smooth balance rod (4), a rotation screw rod (5), a calibrated scale (11) and a protection cover (12) are connected between the upper support (8) and the lower support (9). The smooth balance rod (4), the rotation screw rod (5), the calibrated scale (11) and the protection cover (12) respectively pass through the mobile supporting platform (6). The upper part of the rotation screw rod (5) is fixedly provided with a rotating control rod (7), and the calibrated scale (11) is used for displaying the distance from the current collector to an orbital plane. The device can achieve the convenient, quick and high-precision measurement of static contact forces of upper and lower contact-type current collectors of the electric locomotive on site.
Description
technical field [0001] The invention relates to a static contact force measuring device for a current receiver of an electric locomotive, belonging to the technical field of mechanical measuring devices. Background technique [0002] After the current collector is installed on the electric locomotive, it is necessary to test and adjust the static contact force on the current collector on site to make it within the specified range, so a measuring device is needed to measure the static force of the current collector. [0003] At present, a small spring scale is used to measure the static contact force on site, and its measurement accuracy is not high, and it consumes a lot of physical strength of the testers. Contents of the invention [0004] In order to overcome the deficiencies in the prior art and solve the above technical problems, the present invention provides a static contact force measuring device for current collectors of electric locomotives with light equipment, ...
