Straddle type monorail turnout beam walking supporting trolley

Abstract

The invention discloses a straddle type monorail turnout beam walking supporting trolley. The straddle type monorail turnout beam walking supporting trolley comprises a trolley body and a wheel group.The wheel group comprises two groups of wheels, the wheels in each group of wheels are separately arranged on both sides of the trolley body, an included angle exists between the axes of the two groups of wheels, and the wheels are welded to the trolley body in a fitting mode or are connected with the trolley body by bolts. According to the straddle type monorail turnout beam walking supporting trolley, the wheel group and the trolley body are arranged as a split type structure, and the wheel group is connected with the trolley body by bolts or welded to the trolley body in the fitting mode,so that the overall structural strength of the straddle type monorail turnout beam walking supporting trolley is ensured; and at the same time, the degree of modularity and interchangeability of all parts of the supporting trolley are increased, the manufacturing difficulty is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of rail transit equipment, in particular to a straddle-type single-track turnout beam traveling support trolley. Background technique [0002] In the related art, there is usually a certain angle between the axis of the wheel axle in the trolley of the rail transit turnout beam, and the transition fit between the wheel axle and the axle seat and the bushing ensures that the trolley can support the movement of the turnout beam on the track. However, this kind of turnout The trolley structure of the beam often has the following problems: 1), there is a certain angle between the axis of the wheel axle in the same trolley, which requires high processing requirements for the trolley, and at the same time reduces the production efficiency; 2), the interference between the wheel axle and the axle seat and bushing The machining precision of the matching parts is very high, and the assembly is difficult.
