Embodiment Construction

[0023] Specific embodiments are given below in conjunction with the accompanying drawings, and the vehicle running track with a "convex"-shaped end face of the present invention will be further described in detail.

[0024] see figure 1 , image 3 , Figure 4 with Figure 5 , according to the above-mentioned technical scheme, the "well"-shaped vehicle running track of the present invention is made of cement, including two sets of load-bearing surfaces for carrying the weight of the wheels and the vehicle, a limiting surface and side surfaces for limiting the axial displacement of the wheels, a top surface and The bottom surface has a "convex" cross-section, and the angle β between the bearing surface and the limiting surface is 120° on both sides, and the cross-section is left-right symmetrical. This structure can omit a track when more than two working surfaces are adjacent, such as Figure 7 shown.

Abstract

The invention discloses a "well" shaped intersecting vehicle running track, which comprises a bearing surface for carrying the weight of the vehicle and a limiting surface for limiting the axial displacement of wheels. The bearing surface and the limiting surface are bilaterally symmetrical, and the section is in the shape of "convex". The invention solves the defects of the existing "I"-shaped track that the bearing surface cannot be continuous at the vertical and horizontal intersections, the vehicle is not running smoothly, and the limit surface and the wheel edge have high friction. The vehicle running track of the invention runs smoothly at the intersection, has small friction, and the force on the bearing surface is symmetrical and even.

Description

technical field [0001] The invention relates to a track for rail vehicles, in particular to a track for operating equipment or vehicles in a limited area. Background technique [0002] The cross-sectional shape of the current track is basically "I" shape, the upper plane is used to carry the weight of the vehicle, and one side is used to limit the axial displacement of the vehicle. Its structure is stable, safe and reliable, but there are the following defects at the intersection of the vertical and horizontal tracks: first, the bearing surface cannot be continuous at the intersection of the two vertical and horizontal tracks; second, the sliding friction between the limiting side and the wheel edge is inevitable; The position accuracy between the wheel axial direction and the track width is high, and the manufacturing cost is high. Contents of the invention [0003] Aiming at the above-mentioned problems and defects of the prior art, the object of the present invention i...
