[detailed description of the invention]
Below in conjunction with accompanying drawing, the utility model is described in further detail, and the structure of this device and principle are very clearly concerning the people of this specialty.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Tune rail props up in vertical civil engineering structure substrate by the utility model, by the adjustable leading screw supporting track switch of support both sides, utilizes the deadweight of track switch to form stable supporting system, coordinates cross binding to complete the track condition adjustment of solid concrete roabed track switch.As shown in Figure 1, its structure is divided into two parts: deck type crossbeam adopts can weld the every 50mm place perforate in channel-section steel two ends in length range, is welded into entirety in conjunction with feed screw nut and liner plate.The load-carrying members of this support of deck type crossbeam, adopt a 10# channel-section steel, two round nuts and two blocks of liner plates to be welded to each other and form, sectional dimension is 800mm × 100mm × 48mm.As shown in Fig. 2 (a) He Fig. 2 (b), the 10# channel-section steel circular hole that every 50mm place opens Φ 70mm in the length range of two ends is adopted to be made.Supporting two leading screws support track switch, realize the adjustment to track switch height by two rhizoid thick sticks in rotating nut.Leading screw is used for support track switch, adopt the 45# rod iron processing and fabricating of a Φ 50mm, all heat-treat, sectional dimension is Φ 50mm × 700mm, wherein screw part length is 500mm, and 10mm through hole is bored at leading screw top, inserts adjustment instrument rotating threaded shaft, reach the effect of adjusting pole, as shown in Figure 5.As shown in Figure 3, adopt diameter to be the nonstandard round nut that the 45# steel of Φ 68mm manufactures M50 × 48mm, all heat-treat.After railroad turnout steel rail connects, rail bearing support is arranged by every 3 ~ 4 switch ties, rail bearing support holds separate type on adopting, namely each bearing support only controls absolute altitude and the plan-position of one rail, railway switch or railway frog, the column of bearing support is processed with Ф 50 steel pipe, its top be deck type crossbeam heighten bolt, be liner plate bottom it, make bearing support can be firm fixing alone.As shown in Figure 4, liner plate adopts thickness to be that the Q235 steel plate of 5mm manufactures in the middle part of 100 × 100mm and opens Φ 70mm hole, all heat-treats.
The utility model channel-section steel and nut and liner plate soldering group are dressed up and are adjusted rail support, and length can be determined according to track switch model, and perforate on support rail plate also welds feed screw nut, can realize Height Adjustment by leading screw, coordinate track forces can by track switch modulation level state.For the bulk strength strengthening support rail plate sets liner plate, lower liner plate perforate is corresponding with support rail plate, is welded into entirety by feed screw nut, thus realizes the stable of support.Rotating threaded shaft adjustment track switch height, by track forces and " L " chi determination track original state, and is finally adjusted to and meets design requirement.
Using method of the present utility model is: after track switch being lifted proper height by track jack and hydraulic jack, below rail, place track switch adjust rail, after transferring rail, rail has held by support rail frame, utilizes two ends leading screw to coordinate track forces to need adjustment track switch height according to operation.
Operating procedure is as follows:
(1) with track jack, rail is lifted proper height;
(2) below rail, place track switch adjust rail;
(3) slowly transfer rail, pad adjusts rail to be paved by rail;
(4) need to promote or decline track switch height according to operation.
Rail pad rail bracket operation instruction:
(1) track switch adjusts rail to handle with care, prevents impact damage from deforming;
(2) carefully should check the connection state of each parts before using, peventing member connects loosening or damages;
(3) support rail frame screw and leading screw regularly should add lubrication oil;
(4) slowly should operate during operation, forbid firmly to knock mounting system.
(5) tackle leading screw during track switch railway roadbed concrete construction operation and take safeguard procedures, preventing pollution screw thread.
