摘要:
A monorail track section has a substantially hollow vertical support member (12) terminating in an upper end having an upper transverse leg (16) and a lower wider transverse leg (14). Nut slots (22) are placed in the vertical support member (12) to accommodate nuts (37) which attach various devices to the track section.

The invention is a support structure (150) for a railed-vehicle (54) that includes individual, unassembled components sized for easy transport. In one embodiment, the support structure (150) includes curved columns (160) integrally-formed with a base (162), the columns imparting a curved, Y- shaped configuration to the support structure (150). The components may be prefabricated with known materials and methods and transported to an installation site for assembly. The support structure (150) is preferably sized to support one or two vehicle guideways (152). The support structure (150) may include a pile foundation (56b) for improved support during seismic activity and to facilitate installation on existing streets and sidewalks without covering or interfering with underground plumbing or utilities. Preferably, multiple sections of the guideway (152) are rigidly secured together through expansion joints to define a continuous guideway (152) such that loads on the guideway are distributed over multiple columns (160).

A guideway-based transportation system includes a guideway (22) and a mating vehicle (26), the guideway including a main guideway section (30) that may branch at a branch point (32) into two separate branch sections (34,36), the guideway (22) having a suitable geometry to support and guide the vehicle (26) at any speed reasonably associated with such a transportation system, the vehicle (26) including both support and guide wheels to support the weight of the vehicle (26) and to maintain contact between the vehicle (26) and the guideway (22) as it moves along the guideway, and may optionally include a switching wheel assembly for switching the path of travel of the vehicle (26) from the main guideway section (30) to either of the branch sections (34,36).
摘要:
The invention relates to the area of transport communications, in particular, to the integrated aboveground transport systems of a string type, with transport infrastructure providing speed cargo and passenger traffic. The string transport system by Yunitski represents end (2) and intermediate (3) supports mounted on foundation (1), and at least one rail cord (4) fastened in spans (L) between them, and at least one wheeled vehicle (7) guided thereon. Hereby, load-bearing elements (5) of load-bearing member (6) of rail cord (4) are tensioned and anchored, according to design option, both on end (2) and intermediate (3) anchor supports, which allows to redistribute, between end (2) and intermediate (3) anchor supports, the effect of axial forces which create prestressing of load-bearing elements (5) of rail cord (4). Partial anchoring of load-bearing elements (5) on intermediate (3) anchor supports allows to evenly distribute combined tension force of load-bearing member (6), transferred to intermediate (3) anchor supports, and thereby ensure their load relief, in order to increase stability of end (2) supports, reliability of rail-string transport overpass and achieve "velvet-smooth track" effect, with decrease in material capacity and cost of both supports and load-bearing member (6), alongside with load-bearing elements (5) and rail cord (4) as a whole.
摘要:
The invention relates to the area of transport communications, particularly, to the aboveground (elevated) complex transport systems of string type, which provide high-speed cargo and passenger traffic. Transport system by Yunitski includes track structure (4) tensioned above foundation (1) in spans (2) between supports (3), which comprises aggregated extended body (5), consisting of bearing part (6), containing prestressed load-bearing member (7), and of rail cord (8) connected with it, having rolling surface (A) for motion of vehicle (9) mounted thereon. In bearing part (6) of extended body at height H , m, having variable value in span (2) between supports (3), load-bearing member (7) is fastened, with use of means of reciprocal movement and fixation of arrangement, whereas rail cord (8) is equipped with, at least, two extended longitudinal guide plates (11) of height h, m, positioned axisymmetrically to its longitudinal axis X at distance L from each other, equal to the width of bearing part of extended body. Bearing part and rail cord are configured to be reciprocally moving along the vertical Z and afterfixing to each other at design height P , m, defined by the respective dependence. As a result, high precision of positioning of rolling surfaces ( A ) of rail cord (8) relative to load-bearing member (7), is achieved.
