Description

Technical Field

[0001] The invention relates to a fine adjustment tool and a method thereof, in particular to a fine adjustment tool for a track plate with a large adjustment amount and a fine adjustment method thereof. Background Art

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

[0003] At present, track plate fine-tuning technology is divided into manual track plate fine-tuning technology and automated track plate fine-tuning technology. Among them, manual track plate fine-tuning technology is the main one, and automated track plate fine-tuning technology is a new technology that has been gradually developed and tested in recent years, and it cannot replace manual track plate fine-tuning technology. For manual fine-tuning technology, the fine-tuning methods of the three types of plate-type ballastless track track plates are basically the same, and fine-tuning claws are used to adjust the spatial position of the track plate. Among them, the fine-tuning claws of CRTSⅠ and CRTSⅢ track plates are installed on the reserved lifting holes on the side of the track plate, and there is a space for supporting formwork and edge sealing between the fine-tuning claws and the side of the track plate; the fine-tuning claws of CRTSⅡ track plates are placed on the track plate positioning block (embedded iron seat), and the fine-tuning claws are close to the side of the track plate, and the track plate is sealed with U-shaped foam. The structures of the fine-tuning claws produced by different manufacturers are similar, and they can adjust the track plate in two dimensions (vertical, horizontal) or three dimensions (vertical, horizontal, and longitudinal) and all use manual mechanical adjustment methods of ratchet wrench + screw. The adjustment stroke of the track plate fine-tuning claws does not exceed 85mm vertically, and does not exceed 35mm horizontally and vertically. According to the actual situation of some work sites on the ballastless track of the operating line, the track plate fine-tuning needs to achieve the adjustment requirements of 100mm horizontally and 230mm vertically within the skylight time. The existing track plate fine-tuning technology cannot meet the track plate fine-tuning capability requirements of the operating line ballastless track with large adjustment amounts.

[0004] As for the automatic track plate fine-tuning technology, China has also begun to develop and trial-produce the track plate automatic rapid fine-tuning technology and equipment, and has carried out trial applications. However, due to the complex installation and debugging, low overall efficiency, the equipment affects the track plate buckling, grouting and other processes; the equipment is large in size and weight, and it is difficult to carry it manually. It is difficult to deal with emergencies after a failure, and it is difficult to apply it during the operating line skylight time.

[0005] The existing technologies are all aimed at the fine-tuning construction of track slabs when laying ballastless tracks on new lines, and there is no technical solution for adaptive design of track slab adjustment conditions for ballastless tracks on operating lines. Due to large deformation of the foundation and other reasons, the track slabs of some operating lines need to be fine-tuned by a large amount during the window time, and related processes such as filling layer pouring need to be completed. In view of the fine-tuning conditions and needs of track slabs with large adjustments on ballastless tracks on operating lines, the existing technologies have the following problems:

[0006] (1) According to the actual situation of some work points on the ballastless track of the operating line, the track plate fine-tuning requires a maximum adjustment of 100 mm in the horizontal direction and 250 mm in the vertical direction. The adjustment capacity of the existing track plate fine-tuning technology is approximately 35 mm in the horizontal direction and 85 mm 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 on the ballastless track of the operating line (the most important).

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

[0010] The present invention solves the problem that it is currently impossible to implement a maximum 100mm horizontal and 250mm vertical adjustment and supporting process operation on the track plate of the operating line ballastless track within the skylight time. The existing track plate fine adjustment technology cannot meet the requirements of the track plate fine adjustment capability of the operating line ballastless track with a large adjustment amount. The present invention achieves the above purpose through the following technical solutions.

[0011] The tooling for fine-tuning a track plate with a large adjustment amount comprises a fixing seat, a vertical coarse-adjustment screw, a horizontal coarse-adjustment seat and a lifting hole screw, and is characterized in that: the fixing seat is connected and fixed to the track plate via the lifting hole screw; one end of the vertical coarse-adjustment screw is arranged in a fixing hole on the horizontal coarse-adjustment seat, and the other end is matched and connected with a threaded hole on the fixing seat.

[0012] The present invention also discloses a method for fine-tuning a track plate with a large adjustment amount. The method is based on the above-mentioned fine-tuning tooling for the track plate with a large adjustment amount, and is characterized by:

[0013] Step 1: Installation of track plate fine adjustment tooling;

[0014] Step 2: Lifting of track plate;

[0015] Step 3: Remove the existing filling layer;

[0016] Step 4: Rough adjustment of the track plate;

[0017] Step 5: Temporary pier support;

[0018] Step 6: Remove the track plate rough adjustment tooling;

[0019] Step 7: Fine-tune the track plate;

[0020] Step 8: Edge sealing and pressing of track slab;

[0021] Step 9: New filling and perfusion;

[0022] Step 10: Remove the edge banding and track plate fine-adjustment tooling.

[0023] Beneficial Effects

[0024] The track plate fine-tuning method of the present invention grades the large and small adjustment amounts (corresponding to coarse adjustment and fine adjustment) in the process and integrates them in the tooling, thereby achieving the goal of graded and rapid adjustment of the large adjustment amount of the track plate. A set of tooling can be used to achieve the track plate lifting to provide space for clearing the existing filling layer and fine-tuning of the large adjustment amount of the track plate, and it does not affect the normal progress of the previous and subsequent processes (clearing the existing filling layer, sealing the edges and pouring the new filling layer), thereby achieving the effect of rapid adjustment of the large adjustment amount of the track plate within the skylight time.

DETAILED DESCRIPTION

[0041] Example 1

[0042] The present invention discloses a fine adjustment tool for a track plate with a large adjustment amount, and the specific structure is as follows:

[0043] The large adjustment amount track plate fine adjustment tool 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 transverse coarse adjustment seat 43 is composed of a transverse coarse adjustment slot 431, a transverse coarse adjustment slider 432, a transverse coarse adjustment seat side plate 433, a transverse coarse adjustment seat 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, and the transverse and vertical fine adjustment seat 44 is composed of a transverse fine adjustment base 441, a transverse fine adjustment screw 442, a transverse 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 ).

[0044] The function of the fixing seat 41 is to fix the large adjustment track plate fine adjustment fixture 4 and transfer vertical and lateral loads between the track plate 2 and the large adjustment track plate fine adjustment fixture 4. Two oblong holes are left on it, with the help of which, it is connected and fixed to the lifting hole of the track plate 2 through the lifting hole screw 45. The purpose of the oblong hole 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~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 threaded holes for installing the vertical fine adjustment screw 446 on the fixing seat 41.

[0045] The function of the vertical coarse adjustment screw 42 is to make a large adjustment and quick coarse adjustment of the vertical position of the track plate, and the adjustment amount is 0mm to 250mm. The vertical coarse adjustment screw 42 is connected to the fixed seat 41 by threaded cooperation. 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 fixed 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 transverse 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 transverse coarse adjustment slider 432 is that the supporting base 1 at the bottom of the transverse 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 adapt to the load-bearing, limiting and non-verticality of the vertical coarse adjustment screw 42.

[0046] The transverse coarse adjustment seat 43 is composed of a transverse coarse adjustment slot 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 invert backfill layer, and a tunnel bottom plate). The transverse and vertical fine adjustment seat 44 is composed of a transverse fine adjustment base 441, a transverse fine adjustment screw 442, a transverse 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 load of the track plate. 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 by the vertical fine-tuning pressure plate fixing screw 445. The threaded part of the vertical fine-tuning screw 445 is threadedly connected with 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 to prevent it from being disengaged from the transverse fine-tuning slider 443. The function of the transverse and vertical fine-tuning seat 44 is to fine-tune the transverse and vertical positions of the track plate by a small adjustment amount. The vertical adjustment amount is 0mm to 80mm, and the transverse adjustment amount is 0mm to 40mm. When the track plate is roughly adjusted, the horizontal and vertical fine adjustment seat 44 is suspended on the fixed seat 41 in a state of being unloaded. After the track plate is roughly adjusted to the right position, the horizontal and vertical fine adjustment seat 44 is supported on the temporary support pier 5 and bears 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 precisely 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 Fig. 9 can be seen).

[0047] 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.

[0048] Example 2

[0049] Based on the above-mentioned large adjustment amount track plate fine adjustment tooling, the present invention also discloses a large adjustment amount track plate fine adjustment method, comprising the following steps:

[0050] Step 1: Installation of track plate fine-tuning tooling

[0051] The track plate fine adjustment tool 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 screw 45 to realize the installation of the track plate fine adjustment tool 4 on the track plate 2. The horizontal coarse adjustment seat of the track plate fine adjustment tool 4 is placed on the foundation 1 (see attached Figure 4 , Attachment Figure 5 ).

[0052] Step 2: Track plate lifting

[0053] 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 vertical large adjustment amount track plate fine adjustment tooling to achieve the dual functions of vertical large adjustment amount adjustment of the track plate and large height lifting of the track plate on a set of tooling, which not only solves the problem of insufficient stroke of the existing fine adjustment tooling, but also solves the problems of many types, heavy weight, and insufficient stability of the existing track plate lifting (lifting) tooling.

[0054] Step 3: Removal of existing filling layer

[0055] 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.

[0056] Step 4: Rough adjustment of track plate

[0057] Track plate rough adjustment (see attached Figure 6 , Attachment Figure 7 ) includes rough adjustment of the vertical position of the track plate and rough adjustment of the horizontal position of the track plate. The rough adjustment of the vertical position of the track plate is achieved by screwing the vertical rough adjustment screw 42 of the large adjustment track plate fine adjustment tool 4 to drive the vertical displacement of the fixing seat 41, and then drive the vertical displacement of the track plate 2; the rough adjustment of the horizontal position of the track plate is achieved by screwing the horizontal rough adjustment screw 437 of the large adjustment track plate fine adjustment tool 4 to sequentially drive the horizontal rough adjustment slider 432, the vertical rough adjustment screw 42, and the fixing seat 41 to move horizontally, and then drive the track plate 2 to move horizontally. 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).

[0058] Step 5: Temporary pier support (see attached Figure 8 , Attachment Fig. 9 )

[0059] The temporary pier 5 is placed on the foundation 1. There is a gap in the lower part of the temporary pier 5, which can straddle the top of the transverse coarse adjustment seat 43, so that the transverse coarse adjustment seat 43 can be laterally withdrawn through the gap in the lower part 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 transverse and vertical fine adjustment seat 44; after the temporary pier 5 is placed under the transverse and vertical fine adjustment seat 44, the height of the transverse 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.

[0060] Step 6: Remove the track plate rough adjustment tool (see attached Figure 8 , Attachment Fig. 9 )

[0061] After the horizontal and vertical fine adjustment seat 44 bears the load, the vertical coarse adjustment screw 42 is screwed upward and withdrawn; the unloaded horizontal coarse adjustment seat 43 is withdrawn horizontally from the lower notch 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.

[0062] Step 7: Track plate fine-tuning

[0063] Track plate fine adjustment includes track plate vertical position fine adjustment and track plate transverse position fine adjustment. Track plate vertical position fine adjustment is achieved by screwing vertical fine adjustment screw 446 to drive fixed seat 41 to vertical displacement, and then drive track plate 2 to vertical displacement. Track plate transverse position fine adjustment is achieved by screwing transverse fine adjustment screw 442 to sequentially drive transverse fine adjustment slider 443, vertical fine adjustment screw 446, fixed seat 41 to transverse displacement, and then drive track plate 2 to transverse displacement. The vertical and transverse positions of track plate 2 are precisely adjusted by screwing vertical fine adjustment screw 446 and transverse fine adjustment screw 442 until the target position is reached and the accuracy required is met.

[0064] Step 8: Edge sealing and pressing of track plate (see attached Figure 8 , Attachment Fig. 9 )

[0065] The edge-sealing template 6 is installed around the track plate 2 and the track plate is buckled vertically. 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 foundation 1 and the fixed seat 41 in the vertical direction.

[0066] Step 9: New Filling

[0067] A new filling layer 32 is poured under the track slab 2 .

[0068] Step 10: Remove the edge banding and track plate fine adjustment tooling

[0069] After the new filling layer 32 reaches the required strength, the edge-sealing 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.

[0070] The present invention proposes a track plate fine-tuning method and fine-tuning tooling that meet the adjustment amount, do not affect the previous and next processes, and can be used during the skylight time. The track plate fine-tuning method grades the large and small adjustment amounts (corresponding to coarse adjustment and fine adjustment) in the process and integrates them in the tooling, achieving the goal of graded and rapid adjustment of the track plate with large adjustment amounts. A set of tooling can be used to achieve the lifting of the track plate to provide space for clearing the existing filling layer and fine-tuning of the track plate with large adjustment amounts, and does not affect the normal progress of the previous and next processes (clearing the existing filling layer, sealing the edge and pouring the new filling layer), achieving the effect of rapid adjustment of the track plate with large adjustment amounts during the skylight time.

[0071] The key to the large-adjustment track plate fine-tuning method described in the present invention is the large-adjustment track plate fine-tuning tool 4. The large-adjustment track plate fine-tuning tool 4 adopts a split design of large and small adjustments. The characteristics of the large adjustment part: quickly complete the adjustment of most of the strokes, pursue speed, not precision, and mainly use electric wrenches 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 the track plate is lifted, and the temporary support is removed after completion; during the horizontal adjustment of the large stroke, one-side adjustment is performed, and the other side slides freely to avoid asynchronous holding of strength and increase the load on the lifting hole. Characteristics of the small-adjustment part: accurately complete the adjustment of a small part of the stroke, pursue precision, not speed, and mainly use ratchet wrenches to add force. The vertical maximum is 80mm, and the horizontal maximum is 40mm; for small-stroke adjustment, space for edge sealing is left, the upper space of the track plate is not occupied, and the filling layer is not affected.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention.
