Description

The lower support type track is adjusted bracing frame
Technical field
The utility model relates to a kind of rail supported frame, especially relates to a kind of lower support type track and adjusts bracing frame.
Background technology
At present, in the no tiny fragments of stone, coal, etc. railway roadbed construction of special line for passenger trains, high-speed railway, urban track traffic (as: subway, tram etc.), the non-fragment orbit of sleeper pattern all need at first be finished the adjustment to track circuit, and its adjustment process comprises the basic accuracy adjustment (being called for short " coarse adjustment ") to the rail or the section of track and accurately adjusts (being called for short " accurate adjustment ").After the accurate adjustment parameter meets design requirement, adopt the mould method of building to build railway roadbed concrete (sleeper is fixed), thereby make track circuit have good ride comfort and riding comfort.
Traditional method is the assembly type section of track construction that tiny fragments of stone, coal, etc. railway roadbed is arranged, on the following basal plane of railway roadbed, lay the end tiny fragments of stone, coal, etc. earlier, the section of track of assembling in advance is routed on the circuit with artificial process or Mechanical Method, manually pull out rail to the expection plan-position, again with quality preferably the face tiny fragments of stone, coal, etc. spread to inside and outside the section of track by the railway roadbed size of design and vibrate.When track is adjusted " elevation behind the first plane ",, then need to continue to dial rail up to meeting the demands if there is deviation the plan-position; On the low side as certain section elevation, upwards jack-up is next together with sleeper with rail then to use track jack (or rail jack), clogs railway ballast again and make firm by ramming closely knit under the sleeper of jack-up.When elevation is higher, then digs up railway ballast an amount of under the corresponding sleeper and make firm by ramming closely knit; Assembling must be controlled gauge during the section of track well, if the gauge deviation is bigger, then adjusts gauge.This shows that early stage labour intensity is big when having tiny fragments of stone, coal, etc. track to adjust, efficient is low, circuit line style parameter difference, train running speed is low.
Domestic newly-built track circuit has experienced from the process of the tiny fragments of stone, coal, etc. to the no tiny fragments of stone, coal, etc. arranged, and no tiny fragments of stone, coal, etc. railway roadbed has experienced again by the process of monolithic broad tie to piece formula or long sleeper (III type pillow) concreting railway roadbed or plate-type ballastless track.Broad tie, piece formula pillow or long sleeper need to transfer rail concreting railway roadbed more earlier, and each unit in charge of construction has adopted different supports, method of adjustment, but transfer the principle of rail identical.Wherein: be reserved with the studdle installing hole at its two ends when long sleeper is prefabricated, can only heighten journey, horizontal adjustment must be installed in addition and be adjusted bearing, and adjustment process is loaded down with trivial details, has also increased the instrument input; The function that other adjustment bracing frame can be adjusted elevation and level simultaneously is relatively poor, and the structure heaviness.
