Abstract
Disclosed is a method for mounting an integrated steel rail supporting frame for adjustment of groove type steel rails of a tramcar. The integrated steel rail supporting frame is formed by assembling three sets of tooling equipment in a common steel rail supporting system into a whole. The steel rails are adjusted on a set of tooling during adjustment, space between the steel rails is adjusted through fine adjustment screws on two sides of the supporting frame, the height and the levelness of the steel rails are adjusted through vertical adjusting screws on two sides of the supporting frame, and directions of the steel rails are adjusted by depending on inclined draw bars on the supporting frame. A vertical adjusting device is added on the inner side of each steel rail to adjust the levelness of the rail bottom of the single steel rail simultaneously. Vertical adjustment screws on two sides of the steel rails can be adjusted to achieve standard technical requirements if the rail bottoms of the steel rails fail to meet standard design requirements after the steel rails are erected. According to the method, the efficiency and the accuracy of paving adjustment of groove type steel rails of modern tramcars are improved effectively, operation processes can be simplified, the construction progress can be accelerated, and the production cost can be reduced.
