Description

Technical Field

[0001] The utility model relates to a fine-adjusting tool and a device thereof, in particular to a track plate fine-adjusting tool and a ballastless track laying device thereof. Background Art

[0002] Railway slab track mainly includes CRTSⅠ slab track, CRTSⅡ slab track and CRTSⅢ slab track.

[0003] Currently, track slab fine-tuning technologies are divided into manual and automated. Manual track slab fine-tuning is the primary method, while automated track slab fine-tuning is a new technology that has been gradually developed and trialed in recent years and cannot yet replace manual track slab fine-tuning. Regarding manual fine-tuning, the fine-tuning methods for the three types of slab ballastless track are essentially the same, all using fine-tuning claws to adjust the spatial position of the track slabs. The fine-tuning claws for CRTS I and CRTS III track slabs are installed in pre-reserved lifting holes on the sides of the track slabs, with space for formwork and edge sealing between the fine-tuning claws and the sides of the track slabs. The fine-tuning claws for CRTS II track slabs are placed on the track slab positioning blocks (embedded iron bases), with the fine-tuning claws tightly attached to the sides of the track slabs and used in conjunction with U-shaped foam for edge sealing. The fine-tuning claws produced by different manufacturers have similar structures and can adjust the track slabs in two dimensions (vertical and horizontal) or three dimensions (vertical, horizontal, and vertical). They all use a manual mechanical adjustment method using a ratchet wrench and a screw. The track slab fine-adjustment claws must adjust within a maximum vertical stroke of 85mm and within a maximum horizontal and vertical stroke of 35mm. Based on the actual conditions at some work sites on ballastless track on operating lines, track slab fine-adjustment requires adjustments of 100mm horizontally and 230mm vertically within a specified timeframe. Existing track slab fine-adjustment technologies are unable to meet the requirements for large-scale track slab fine-adjustment on operating lines.

[0004] Regarding automated track slab fine-tuning technology, China has also begun developing and trial-producing automated rapid track slab fine-tuning technology and equipment, and has conducted trial applications. However, due to the complexity of installation and commissioning, overall efficiency is low, and the equipment affects processes such as track slab buckling and grouting. Furthermore, the equipment is large in size and weight, making manual handling difficult, and emergency response after failures are difficult, making it difficult to apply during operating hours on the line.

[0005] Existing technologies are all focused on fine-tuning track slabs during the laying of ballastless track on newly constructed lines. There are no technical solutions designed to adapt to the adjustment conditions of track slabs on ballastless track on operating lines. Due to significant foundation deformation and other factors, some ballastless track slabs on operating lines require large adjustments and fine-tuning within a short timeframe, along with the completion of related processes such as filling and pouring the filling layer. Regarding the conditions and requirements for fine-tuning track slabs on ballastless track on operating lines, existing technologies have the following problems:

[0006] (1) According to the actual situation of some work sites on the ballastless track of the operating line, the track plate fine-tuning requires a maximum adjustment of 100mm in the horizontal direction and 250mm in the vertical direction. The adjustment capacity of the existing track plate fine-tuning technology is approximately 35mm in the horizontal direction and 85mm in the vertical direction. The existing track plate fine-tuning technology cannot meet the requirements of the track plate fine-tuning capacity with large adjustment amounts for the ballastless track of the operating line (the most important requirement).

[0007] (2) The characteristics of fine-tuning large track slab adjustments on operating lines are that the track slab needs to be lifted at least 200mm before adjustment to remove the existing filling layer, and the track slab needs to be edge-sealed and poured with a new filling layer after adjustment. Existing track slab adjustment technology does not take into account the process connection characteristics before and after the adjustment of the operating line track slab, and does not have the ability to lift the track slab at least 200mm before adjustment. Multiple relay lifting of the track slab after large adjustments will also affect the edge sealing and pouring of the new filling layer.

[0008] (3) If the existing adjustment tooling design is not changed, multiple relays will be required to complete the required adjustment amount, which will complicate the track plate fine-tuning process, increase the difficulty of personnel operation, greatly increase the adjustment time, and cannot guarantee the overall stability of the track plate and the accuracy maintenance ability of the track plate after fine-tuning.

[0009] Therefore, it is necessary to propose a large-adjustment track plate fine-tuning technology for the ballastless track of the operating line railway, which can be implemented within the window time. Its main features are: meeting the requirements of large stroke and precision, meeting the operation requirements during the window time, lightweight, strong emergency response capabilities, and considering the connection of related processes such as jacking and chiseling out the existing filling layer, edge sealing, and pouring the new filling layer.

DETAILED DESCRIPTION

[0038] Example 1

[0039] Track plate fine adjustment fixture, the specific structure is as follows:

[0040] The large adjustment track plate fine adjustment fixture 4 is composed of five parts: a fixed seat 41, a vertical coarse adjustment screw 42, a horizontal coarse adjustment seat 43, a horizontal and vertical fine adjustment seat 44 and a lifting hole screw 45 (see attached Figure 1 ); wherein the horizontal coarse adjustment seat 43 is composed of a horizontal coarse adjustment slot 431, a horizontal coarse adjustment slider 432, a horizontal coarse adjustment seat side plate 433, a horizontal coarse adjustment seat side plate fixing screw 434, a horizontal coarse adjustment seat pressure plate 435, a horizontal coarse adjustment seat fixing screw 436 and a horizontal coarse adjustment screw, and the horizontal and vertical fine adjustment seat 44 is composed of a horizontal fine adjustment base 441, a horizontal fine adjustment screw 442, a horizontal fine adjustment slider 443, a vertical fine adjustment pressure plate 444, a vertical fine adjustment pressure plate fixing screw 445, and a vertical fine adjustment screw 446 (see attached Figure 2 ).

[0041] The function of the fixing seat 41 is to fix the large adjustment amount track plate fine adjustment fixture 4 and transfer vertical and lateral loads between the track plate 2 and the large adjustment amount track plate fine adjustment fixture 4. There are two oblong holes on it, with the help of which the lifting hole screw 45 is connected and fixed to the lifting hole of the track plate 2. The purpose of the oblong holes is to be compatible with the different center distances of the lifting holes of different track plates (each track plate is provided with lifting holes at the four corners, and each of the two lifting holes bears loads at the same time, and the center distance between the two lifting holes at each corner is 120mm to 160mm). There is a handle for carrying on the upper part of the fixing seat 41, and there are threaded holes for installing the vertical coarse adjustment screw 42 and the threaded hole for installing the vertical fine adjustment screw 446 on the fixing seat 41.

[0042] The function of the vertical coarse adjustment screw 42 is to quickly and roughly adjust the vertical position of the track plate with a large adjustment amount, and the adjustment amount is 0mm to 250mm. The vertical coarse adjustment screw 42 is connected to the fixing seat 41 through a threaded fit. When working, the vertical coarse adjustment screw 42 is screwed to convert the rotational motion of the vertical coarse adjustment screw 42 into the vertical displacement motion of the fixing seat 41. The lower end of the vertical coarse adjustment screw 42 is a hemispherical support end, which is supported in the hemispherical pit of the horizontal coarse adjustment slider 432 when working. The reason why the lower end of the vertical coarse adjustment screw 42 is supported in the hemispherical pit of the horizontal coarse adjustment slider 432 is that the supporting base 1 at the bottom of the horizontal coarse adjustment slider 431 is often not perpendicular to the side of the track plate 2, and there is generally a drainage slope. The hemispherical pit can play a role in the bearing, limiting and non-vertical adaptation of the vertical coarse adjustment screw 42.

[0043] The transverse coarse adjustment seat 43 is composed of a transverse coarse adjustment chute 431, a transverse coarse adjustment slider 432, a transverse coarse adjustment side plate 433, a transverse coarse adjustment side plate fixing screw 434, a transverse coarse adjustment seat pressure plate 435, a transverse coarse adjustment seat fixing screw 436, and a transverse coarse adjustment screw. The function of the transverse coarse adjustment seat 43 is to quickly and roughly adjust the transverse position of the track plate by a large adjustment amount, and the adjustment amount is 0mm to 150mm. The transverse coarse adjustment seat 43 is placed on the foundation 1 (for different offline foundations, the foundation 1 includes a base, a supporting layer, a bridge deck, a bridge deck protection layer, a tunnel arch backfill layer, and a tunnel floor).

[0044] The horizontal and vertical fine-adjustment seat 44 is composed of a horizontal fine-adjustment base 441, a horizontal fine-adjustment screw 442, a horizontal fine-adjustment slider 443, a vertical fine-adjustment pressure plate 444, a vertical fine-adjustment pressure plate fixing screw 445 and a vertical fine-adjustment screw 445. The transverse fine-tuning base 441 is supported on the temporary support pier 5 when bearing the track plate load. The convex edge of the transverse fine-tuning screw 442 is embedded in the notch of the transverse fine-tuning base 441. The transverse fine-tuning slider 443 and the transverse fine-tuning base 441 form a slider guide structure. The vertical fine-tuning pressure plate 444 is fixed to the transverse fine-tuning slider 443 using the vertical fine-tuning pressure plate fixing screw 445. The threaded portion of the vertical fine-tuning screw 445 is threadedly connected to the fixing seat 41. The hemispherical support end at the lower end of the vertical fine-tuning screw 445 is supported in the hemispherical pit of the transverse fine-tuning slider 443. The convex edge at the lower end of the vertical fine-tuning screw 445 is restricted by the vertical fine-tuning pressure plate 444 in its vertical upward displacement to prevent it from disengaging from the transverse fine-tuning slider 443. The function of the transverse and vertical fine-tuning base 44 is to fine-tune the transverse and vertical positions of the track plate by small adjustments. The vertical adjustment amount is 0mm to 80mm, and the transverse adjustment amount is 0mm to 40mm. When the track plate is coarsely adjusted, the horizontal and vertical fine adjustment seats 44 are suspended on the fixed seat 41 in an unloaded state. After the track plate is coarsely adjusted to the right position, the horizontal and vertical fine adjustment seats 44 are supported on the temporary support pier 5 and bear the entire load of the track plate. At the same time, the vertical coarse adjustment screw 42 and the horizontal coarse adjustment seat 43 are withdrawn, and the track plate is further accurately adjusted. The purpose of withdrawing the vertical coarse adjustment screw 42 and the horizontal coarse adjustment seat 43 is to provide space for the subsequent edge sealing of the track plate 2 (from the attached Figure 8 , Attachment Figure 9 can be seen).

[0045] The function of the lifting hole screw 45 is to connect and fix the large adjustment amount track plate fine adjustment tool 4 to the track plate 2 through the lifting hole of the track plate 2.

[0046] Example 2

[0047] A method for fine-tuning a track plate with a large adjustment amount is implemented based on the above-mentioned fine-tuning tool for fine-tuning a track plate with a large adjustment amount, comprising the following steps:

[0048] Step 1: Install the track plate fine-tuning tooling

[0049] The track plate fine adjustment fixture is installed on the existing lifting holes at the four corners of the track plate. At the lifting holes on the side of the track plate 2, the fixing seat 41 is installed through the lifting hole screws 45 to achieve the installation of the track plate fine adjustment fixture 4 on the track plate 2. The horizontal coarse adjustment seat of the track plate fine adjustment fixture 4 is placed on the foundation 1 (see attached Figure 4 , Attachment Figure 5 ).

[0050] Step 2: Track plate lifting

[0051] The track plate jacking is achieved by screwing the vertical coarse adjustment screw 42 of the large adjustment track plate fine adjustment tool 4 to drive the fixing seat 41 to move vertically, thereby driving the track plate 2 to move vertically. The purpose of the track plate jacking is to provide working space for removing the existing filling layer under the track plate (see attached Figure 6 , Attachment Figure 7 This method uses a track plate fine-adjustment tooling with a large vertical adjustment amount to achieve the dual functions of adjusting the track plate with a large vertical adjustment amount and lifting the track plate to a large height on a single set of tooling, thereby solving the problem of insufficient stroke of the existing fine-adjustment tooling and the problems of the existing track plate lifting (lifting) tooling with multiple types, heavy weight, and insufficient stability.

[0052] Step 3: Remove the existing filling layer

[0053] Remove the existing filling layer 31 below the track plate 2. To save time, this step is performed synchronously with the track plate 2 rough adjustment.

[0054] Step 4: Track plate rough adjustment

[0055] Track plate coarse adjustment (see attached Figure 6 , Attachment Figure 7 ) includes coarse adjustment of the vertical position of the track plate and coarse adjustment of the horizontal position of the track plate. The coarse adjustment of the vertical position of the track plate is achieved by rotating the vertical coarse adjustment screw 42 of the large-adjustment track plate fine-adjustment fixture 4 to drive the vertical displacement of the fixing seat 41, thereby driving the vertical displacement of the track plate 2; the coarse adjustment of the horizontal position of the track plate is achieved by rotating the horizontal coarse adjustment screw 437 of the large-adjustment track plate fine-adjustment fixture 4 to sequentially drive the horizontal coarse adjustment slider 432, the vertical coarse adjustment screw 42, and the fixing seat 41 to move laterally, thereby driving the horizontal displacement of the track plate 2. The purpose of this step is to quickly adjust the horizontal and vertical positions of the track plate 2, and to quickly complete most of the adjustment (the skylight time is limited).

[0056] Step 5: Temporary pier support (see attached Figure 8 , Attachment Figure 9 )

[0057] The temporary pier 5 is placed on the foundation 1. There is a gap at the bottom of the temporary pier 5, which can straddle the top of the horizontal coarse adjustment seat 43 so that the horizontal coarse adjustment seat 43 can be laterally withdrawn through the gap at the bottom of the temporary pier 5 when there is no load. The height of the temporary pier 5 is adjusted by replacing different models or adding / removing pads so that it can be placed under the horizontal and vertical fine adjustment seat 44. After the temporary pier 5 is placed under the horizontal and vertical fine adjustment seat 44, the height of the horizontal and vertical fine adjustment seat 44 is lowered by screwing the vertical fine adjustment screw 446 so that it is supported on the upper surface of the temporary pier 5.

[0058] Step 6: Remove the track plate coarse adjustment tool (see attached Figure 8 , Attachment Figure 9 )

[0059] After the horizontal and vertical fine adjustment seat 44 is loaded, the vertical coarse adjustment screw 42 is screwed upward and withdrawn; the unloaded horizontal coarse adjustment seat 43 is withdrawn horizontally from the gap at the bottom of the temporary pier 5; the purpose of withdrawing the vertical coarse adjustment screw 42 and the horizontal coarse adjustment seat 43 is to provide space for the subsequent edge sealing of the track plate 2.

[0060] Step 7: Track Plate Fine Adjustment

[0061] Track plate fine-tuning includes fine-tuning the vertical position of the track plate and fine-tuning the horizontal position of the track plate. Fine-tuning the vertical position of the track plate is achieved by rotating the vertical fine-tuning screw 446 to drive the vertical displacement of the fixing seat 41, thereby driving the vertical displacement of the track plate 2. Fine-tuning the horizontal position of the track plate is achieved by rotating the horizontal fine-tuning screw 442, which in turn drives the horizontal fine-tuning slider 443, the vertical fine-tuning screw 446, and the fixing seat 41 to move horizontally, thereby driving the horizontal displacement of the track plate 2. By rotating the vertical fine-tuning screw 446 and the horizontal fine-tuning screw 442, the vertical and horizontal positions of the track plate 2 are precisely adjusted until the target position is reached and the required accuracy is met.

[0062] Step 8: Track plate edge sealing and buckling (see attached Figure 8 , Attachment Figure 9 )

[0063] The edge-sealing template 6 is installed around the track plate 2 and the track plate is vertically buckled. The track plate edge-sealing template is located between the track plate 2 and the horizontal and vertical fine adjustment seat 44 in the horizontal direction and between the base 1 and the fixed seat 41 in the vertical direction.

[0064] Step 9: New Filling

[0065] A new filling layer 32 is poured under the track slab 2 .

[0066] Step 10: Remove the edge banding and track plate fine adjustment tooling

[0067] After the new filling layer 32 reaches the required strength, the edge banding template 6 and the remaining part of the track plate fine adjustment tool 4 are removed. At this point, the large adjustment amount fine adjustment of the track plate 2 is completed.

[0068] Example 3

[0069] Based on the above-mentioned track plate fine-adjusting tool and the large-adjustment track plate fine-adjusting method thereof, the utility model further discloses a ballastless track laying device, which includes the above-mentioned track plate fine-adjusting tool.

[0070] The utility model proposes a track plate fine-tuning method and fine-tuning tooling that meet the adjustment requirements, do not affect the preceding and following processes, and can be used within a time window. The track plate fine-tuning method divides the large and small adjustment amounts (corresponding to coarse adjustment and fine adjustment) into grades in the process and integrates them in the tooling, achieving the goal of graded and rapid adjustment of large track plate adjustments. A set of tooling can be used to lift the track plate to provide space for clearing the existing filling layer and fine-tune the track plate by large adjustments, without affecting the normal progress of the preceding and following processes (clearing the existing filling layer, sealing the edges and pouring the new filling layer), achieving the effect of quickly adjusting large track plate adjustments within a time window.

[0071] The key to the present invention is the large-adjustment track plate fine-tuning fixture 4. The large-adjustment track plate fine-tuning fixture 4 adopts a split design for large and small adjustments. The characteristics of the large-adjustment part are: it can quickly complete the adjustment of most strokes, pursue speed, not precision, and mainly adopt an electric wrench to add force. The vertical maximum is 250mm, and the horizontal maximum is 150mm; for large-stroke adjustment, the existing filling layer is removed after lifting the track plate, and the temporary support is removed after completion; during large-stroke horizontal adjustment, one-side adjustment is performed, and the other side slides freely to avoid asynchronous tension and increase the load on the lifting hole. The characteristics of the small-adjustment part are: it can accurately complete the adjustment of a small part of the stroke, pursue precision, not speed, and mainly adopt a ratchet wrench to add force. The vertical maximum is 80mm, and the horizontal maximum is 40mm; for small-stroke adjustment, space for edge sealing is left, which does not occupy the upper space of the track plate and does not affect the pouring of the filling layer.

[0072] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention.
