Detailed Description

The monorail travelling wheel set provided by the invention is further described in detail with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more fully apparent from the following description and appended claims. It should be noted that the drawings are in simplified form and are not to precise scale, and are provided for convenience and clarity in order to facilitate the description of the embodiments of the present invention.

Example one

The utility model provides a monorail travelling wheel group, the structure of which is shown in figure 1. The monorail travelling wheel set comprises a chassis 1 and travelling wheels 2 which are rotatably arranged at two ends of the chassis 1, and further comprises a plurality of suspension wheels 3 and a plurality of guide wheels 4, wherein the suspension wheels 3 and the guide wheels 4 are symmetrically and rotatably arranged at two sides of the chassis 1; the axis of the suspension wheel 3 is along the transverse direction, and the axial direction of the guide wheel 4 is along the vertical direction; the suspension wheels 3 are hooked at the bottoms of two sides of the rail head of the steel rail, and the guide wheels 4 are closely attached to two sides of the rail head. The monorail travelling wheel group can drive railway maintenance equipment to move along the monorail when playing the supporting role, and whole size is less, conveniently deposits and transport, and when removing, hang wheel 3 with the tight track of guide wheel 4 clamp from both sides can be followed to the leading wheel, avoids maintenance equipment to take place horizontal drunkenness in operation and removal process, influences the work precision.

Because the bottoms of the two sides of the railway railhead are inclined planes, the side surface of the suspension wheel 3 is provided with a conical surface 30 matched with the inclined plane of the bottom of the steel rail railhead.
