Description

Technical Field

[0001] This invention relates to the field of tram retrofitting technology, and in particular to temporary superimposed turnouts and construction methods for tram retrofitting without interrupting operation. Background Technology

[0002] Trams are mainly laid along the surface of urban municipal roads, using ballastless tracks. Some sections have dedicated right-of-way with green paving, while others are paved with asphalt when intersecting with municipal roads.

[0003] Tram lines are located in complex environments, and their roadbed structures are easily affected by the construction or settlement of surrounding buildings, roads, and culverts, leading to tram line settlement. This necessitates roadbed structure lifting and track alignment repair. The track structure also requires repair or replacement due to impacts from vehicles or its own wear, fatigue, aging, and quality issues. When upgrading or repairing the line, such as installing turnouts on existing lines, installing turnouts on new lines, upgrading existing lines to higher speeds, or modifying the overhead contact system, the existing line must be dismantled and altered.

[0004] Current status and shortcomings of the technology in this field:

[0005] (1) Some minor local modifications to existing trams are carried out during nighttime maintenance windows. In order not to affect the operation the next day, some fast-setting materials or special operations are often used, such as fast-setting mortar. However, these fast-setting materials are feasible in the short term but have questionable long-term reliability. There is a problem of repeated operations in the later stage. The materials used for temporary modifications are not conducive to long-term stability.

[0006] (2) Some major upgrades, renovations or repairs require interrupting existing operating lines and stopping tram operations. In some areas, public transport connections are used. This not only involves engineering and technical issues but also the maintenance of social road traffic organization, resulting in higher costs and greater social impact.

[0007] Therefore, how to solve the problem of the entire line being interrupted during the maintenance or renovation of existing tracks has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0008] In view of the above-mentioned deficiencies of the prior art, the present invention provides a temporary superimposed turnout and construction method for the non-stop operation transformation of trams, the purpose of which is to solve the problem of the interruption of the entire line during the maintenance or transformation of existing tracks.

[0070] Example: Figures 1 to 4 As shown, a temporary superimposed turnout is used for the conversion of trams to operate without interruption. When there is a breakpoint 8 on one of the double-track lines that needs to be shut down, the part of the breakpoint 8 is connected to the other line.

[0071] Among them, the temporary superimposed turnouts 6 are set in pairs on the existing track 9 before and after the breakpoint 8;

[0072] Each temporary superimposed turnout 6 is in the shape of an "r" and includes a main track section and a turnout section;

[0074] Each branch section includes a branch overlap section, a transition section 2, and a standard guide rail 4 set between the branch overlap section and the transition section 2;

[0075] Each branch line overlaps with one of the existing tracks 9 located before or after the breakpoint 8 in the double track.

[0076] Each transition section 2 is located at the end where the corresponding branch section connects to the corresponding main track section;

[0077] The intersection of the standard guide rail 4 of the main road section and the standard guide rail 4 of the branch road section forms the intersection section 3;

[0078] The section near the end of each intersection and each main road intersection is a climbing transition section 1;

[0079] Each climbing transition section 1 includes a gradually increasing guide rail 101 set on the existing track 9;

[0080] The portion of each gradient guide rail 101 with a height of less than 40 mm from the rail surface of the corresponding existing rail 9 is laid flat on the rail surface of the corresponding existing rail 9, and the lower surface that contacts the rail surface of the corresponding existing rail 9 is an upward concave inverted "U" shape, which is stuck in the rail head of the corresponding existing rail 9.

[0081] For each gradient guide rail 101, the portion where the height from the rail surface to the rail surface of the corresponding existing rail 9 exceeds 40 mm, a ramp transition steel base plate 104 is provided between the rail surface and the corresponding existing rail 9.

[0082] Each ramp transition steel base plate 104 is fixedly connected to the corresponding existing track 9 track hard paving 7;

[0083] For each climbing transition steel base plate 104, the portion of the rail surface of the corresponding gradual guide rail 101 that is less than 55 mm above the rail surface of the corresponding existing rail 9 is provided with a steel base plate transition groove 105 that penetrates both the upper and lower surfaces of the grooved steel rail wheel flange groove of the corresponding existing rail 9.

[0084] For the portion of each gradient guide rail 101 where the height from the rail surface to the rail surface of the corresponding existing rail 9 is more than 55 mm, a gradient rail flange groove 106 is provided on the side of the corresponding gradient guide rail 101 at the position corresponding to the grooved rail flange groove of the corresponding existing rail 9.

[0085] Each existing track 9 has an open buffer section 107 at the beginning, which is connected to the corresponding steel base plate transition groove 105 through the corresponding open buffer section 107.

[0092] This invention Figure 1 The diagram shows an arrangement with openings to the right, while the openings to the left are arranged symmetrically.

[0093] The present invention uses a temporary superimposed turnout 6 superimposed on a double-track line before and after a breakpoint 8 that needs to be stopped, without damaging the existing track 9 structure and maintaining the integrity of the existing track 9.

[0094] Each gradient guide rail 101 has an upward-concave inverted "U" shape when it contacts the rail surface of the corresponding existing rail 9. When it is locked at the rail head of the corresponding existing rail 9, it can restrict the left and right movement of the gradient guide rail 101.

[0095] The presence of the gradient rail flange groove 106 on the side of the gradient guide rail 101 and the open buffer section 107 and steel base plate transition groove 105 on the climbing transition steel base plate 104 can prevent the wheel from hitting the tip.

[0096] In some embodiments, each gradient guide rail 101 includes a tongue tip 102 located at an end, and a ramp section 103 connected to the tongue tip 102;

[0097] Each tongue tip 102 is a right trapezoid in longitudinal section, with the length of the right-angled side being 25 mm ± 5% and closely attached to the corresponding existing track 9. The smaller base side is 2 mm ± 5% and faces the direction of vehicle entry or exit, while the larger base side is connected to the climbing section 103. The slope of the hypotenuse relative to the existing track 9 is 16%.

[0098] Each climbing section 103 has a right trapezoidal shape in its longitudinal section, with the hypotenuse having a slope of 4% relative to the existing track 9.

[0100] In some embodiments, each transition section steel base plate 21, each climbing transition steel base plate 104, and each intersection section steel base plate 31 are fixedly connected to the track hard paving 7 of the existing track 9 within the coverage area by multiple anchor bolts 10, and are fixedly connected to the corresponding part of the corresponding main track section or the corresponding branch track section by welding.

[0101] Each locking boss 5 is fixed to the corresponding transition section steel base plate 21 or the corresponding ramp transition steel base plate 104 by welding.

[0102] Each conversion guide rail is fixed to the corresponding conversion section steel base plate 21 by welding;

[0103] The height of the rail surface of each conversion guide body from the rail surface of the corresponding existing rail 9 is 80 mm.

[0104] In practical applications, the positioning boss 5 facilitates installation and positioning and restricts the lateral movement of the steel base plate.

[0105] In some embodiments, the two transition section steel base plates 21 of each transition section 2 are welded together by multiple connecting steel plates 24.

[0106] In some embodiments, the height of the rail surface of each standard guide rail 4 from the rail surface of the corresponding existing rail 9 is 80mm, and they are all fixed to the corresponding steel sleeper 41 by welding.

[0107] Each steel sleeper 41 is fixed to the corresponding track hard paving 7 surface layer by anchor bolts 10.

[0108] The present invention also provides a construction method for temporary superimposed turnouts for tram non-stop conversion, comprising the following steps:

[0109] Step 1: Based on the scope of the construction and renovation area, remove the paving layer within the track bed surrounding the temporary superimposed turnout 6 that needs to be installed, and use concrete backfill to lay new hard track paving 7 along each turnout section.

[0110] Step 2: After the hard pavement reaches the specified strength, take advantage of the nighttime track window to stack each temporary turnout 6 onto the corresponding existing track 9 and finely adjust the temporary fixation.

[0111] Step 3: Holes for installing anchor bolts 10 are made on the surface layer of the track hard paving 7 where the transition section steel base plate 21, the climbing transition steel base plate 104, the cross section steel base plate 31 and the connecting steel sleepers need to be laid.

[0112] Anchor bolts 10 are used to fix all transition section steel base plates 21, all climbing transition steel base plates 104, steel sleepers of standard guide rail 4 sections and all intersection section steel base plates 31 with chemical bolts or expansion bolts, and finally fine-tuning and fixing temporary superimposed turnouts 6;

[0113] Step 4: Conduct multiple driving tests using a tram.

[0114] Step 5: Set up barriers in the area requiring construction and renovation at breakpoint 8, and carry out construction at breakpoint 8.

[0115] Step 6: During normal operation, the tram will operate as a passenger vehicle along another uninterrupted line 8 formed by two temporary superimposed switches 6.

[0116] Step 7: After 80% of the construction is completed at the break point, remove the temporary superimposed turnout 6;

[0117] Step 8: Repeat steps 1 to 7 to complete the construction of all breakpoints 8.
