Description
Technical field
This application involves suspension type transport fields, and in particular to the track girder and its processing work of suspension type rail communications and transportation
Skill.
Background technique
Suspension type rail communications and transportation had both belonged to suspension type transport field from classification, while still belonging to rail traffic
Transport field, suspension type transport generally include to classify by its application field, and the suspension type including being applied to rail traffic is transported
It is defeated, nose suspension type transports defeated applied to the row handling in various workshops, applied to tourist facilities；And rail vehicle transportation field is then
Including track transport, magnetic-levitation transport and suspension type rail transport.Specific to suspension type rail communications and transportation
Speech, used material, track structure etc. have the difference of essence with other field.
The track girder of existing suspension type rail communications and transportation is usually following several structures:
The first: i.e. open type single structure beam form formula is the traveling space of motor-car below open type single structure beam, opens wide
Two outside of left and right of formula single structure beam supports two wheels of motor-car respectively.
Second: i.e. box shaped beam mode, inside, that is, motor-car traveling space of box shaped beam, the wheel branch of motor-car
Support the two inside Board positions in box shaped beam.

Steel using amount be considerably less than existing track beam element structure.
Although the application specific embodiment only lists the segment thickness of main structure, the part of track beam element is long
Degree, and the measured data in the case where carrying the beam element load-carrying of 60t/ track, but this has no effect on the complete of application scheme
Whole independence, i.e. the applicant learn that application scheme is identical as existing comparative run in other parameters data by every verifying
(either 50t load-carrying, 40t load-carrying and following thickness, the track girder for being perhaps greater than other main structures of 60t load-carrying or use
Match parameter between the length of unit), and meet the vertical static deformation amount δ of track beam element no more than y (track beam element
Length) under the premise of/800 (mm), gained steel using amount is significantly lower than existing track beam element structure, and specific embodiment part is only made
To illustrate.
In addition, from table one, it can be deduced that, when the length of the thickness of the first main body, the second main body, track beam element meets
When special ratios relationship, such as the thickness x (unit: mm) of the first main body or the second main body and length y of track beam element (single
Position: the relationship between m) is: y=-ax2+ bx-c, a are 0.01-0.015, and b is 1.1-1.4, and c is 0.5-2.5；Its gained track
Beam element is under the premise of meeting vertical static deformation amount δ no more than y (track girder element length)/800 (mm), track beam element
Unit load-carrying steel using amount it is considerably lower.
The same or similar parts between the embodiments can be referred to each other in present specification.Especially for system
