Description

Technical Field

[0001] This invention relates to the field of track laying technology, and in particular to a method and equipment for rapid track laying across tracks. Background Technology

[0002] In adjacent track laying, one currently used method is the towing method. This involves using the existing track for adjacent track laying. The rail transport vehicle is aligned, and the rail-separating mechanism is adjusted laterally and vertically to correspond to the position of the rail to be towed. The rail is then towed and pushed through multiple rail-aligning mechanisms until the rail head is placed in the predetermined rail groove. The vehicle then makes slight adjustments to align the new rail with the existing rail, securing the rail fasteners at the joints. The locomotive then advances at a constant speed to lower the adjacent rail into the groove. Since the length of each rail is fixed, during adjacent track laying, the entire process must be repeated after the previous rail is laid. The time spent on rail threading and alignment cannot be reduced, resulting in low laying efficiency. In complex areas, the reliability of the equipment is reduced, and this method also requires more manpower. Therefore, further improvements are needed. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of the aforementioned background technology by providing a solution that is suitable for complex areas and enables rapid track laying across lines.

[0004] To achieve the above objectives, the present invention provides a rapid cross-track track laying method, characterized by comprising the following steps:

[0005] S1. After preparation is complete, the rails are loaded onto the track-laying machine, and the track-laying machine is moved to the track-laying location.

[0006] S2, the guide section of each guide mechanism moves to the first preset position;

[0007] S3, the rails to be laid are unlocked on the rail laying machine and separated by the rail splitting mechanism. The rails are then pushed by the dragging and pushing mechanism so that they pass through the guide section of the first rail shifting mechanism and continue to be pushed backward. As the rails are pushed to the next rail shifting mechanism, the guide section of the previous rail shifting mechanism adjusts its position until the rails can pass smoothly through the guide section of the next rail shifting mechanism. Finally, the guide sections of each rail shifting mechanism move to the second preset position so that the rail head moves into the rail bearing groove of the adjacent line.

[0008] At the same time, the rail head of the rail to be laid is connected to the rail tail of the rail being laid through a rail clamping structure;

[0009] S4, the track laying machine moves forward at a constant speed, so that the rail to be laid is unloaded and put into the groove. At this time, the rail head and rail clamping structure of the rail to be laid are also located in the rail bearing groove of the adjacent line.

[0010] S5, disassemble the rail clamping structure and install the rail fasteners at the joint;

[0011] S6, the track-laying unit continues to move forward at a constant speed, continuously unloading multiple rails into the groove on the adjacent line, repeating S5 to complete the track-laying operation on the adjacent line.

[0012] The present invention also provides a rapid track laying device for crossing lines, which adopts a rapid track laying method for crossing lines as described above, including a pusher, multiple track flatcars, multiple track shifting mechanisms, and multiple track clamps;

[0013] The pusher car sequentially pulls each of the track flat cars, and the pusher car is equipped with a track splitting mechanism and a pulling and pushing mechanism;

[0014] The rail-shifting mechanism is installed on the corresponding rail flatcar. Each rail-shifting mechanism is equipped with a rail-shifting guide. The rail-shifting guide is used to guide and shift the rail, so that the rail is pushed from the current line to the adjacent line according to a preset path.

[0015] The rail clamp is used to clamp and connect the rail being laid and the rail to be laid in order to carry out continuous rail laying.

[0016] Furthermore, the rail clamp includes a clamp base, a clamping opening at the first end of the clamp base, into which the web of the rail can be inserted. A clamping block is provided inside the clamp base, and the clamping block is provided with a clamping surface that can extend into the clamping opening to clamp the rail. A locking component is provided inside the clamp base and is connected to the clamping block.

[0017] Furthermore, the locking assembly includes a spring buckle plate, an elastic element, a connecting rod, and a first limiting pin. The clamping block is rotatably connected to the clamping seat. The first end of the spring buckle plate is rotatably connected to the clamping seat, and the second end of the spring buckle plate is connected to the elastic element. The elastic element is also connected to the clamping block. When the spring buckle plate rotates, the length of the elastic element tends to change to provide traction force to drive the clamping block to rotate. The first end of the connecting rod is rotatably connected to the clamping block, and the second end of the connecting rod is slidably disposed in a limiting groove opened at the second end of the clamping seat through the first limiting pin. The two rail clamps are connected by a connecting chain, and the connecting chain is sleeved in the corresponding first limiting pin.

[0018] Furthermore, the locking assembly also includes a second limiting pin, which is located on the rotation path of the second end of the spring buckle. During the forward rotation of the spring buckle until it abuts against the second limiting pin, the elastic element first reaches its maximum length, then shortens by a small segment and cannot rotate further. After the spring buckle abuts against the second limiting pin, the elastic element stretches when the spring buckle rotates in the reverse direction.

[0019] Furthermore, the elastic element is a spring.

[0020] The above-described solution of the present invention has the following beneficial effects:

[0021] The rapid cross-line track laying method and equipment provided by this invention can continuously lay multiple adjacent rails without repeating rail threading and alignment when laying each rail, thus saving track laying time and improving efficiency. This is particularly significant when laying rails in complex areas. The two rails are connected by rail clamps, which adopt a simple and easy-to-operate elastic locking method. Installation and disassembly are very convenient, preventing the rail clamps from loosening and disengaging due to back-and-forth movement of the rails. This improves the feasibility, reliability, and convenience of continuous track laying.

[0022] Other beneficial effects of the present invention will be described in detail in the following detailed description section. Attached Figure Description

For example, they can refer to a locking connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] like Figure 1 As shown, an embodiment of the present invention provides a method for rapid track laying across railway lines, comprising the following steps:

[0033] S1. After preparation is complete, the rails are loaded onto the track-laying machine, and the track-laying machine is moved to the track-laying location.

[0034] S2, the guide section of each guide mechanism moves to the first preset position;

[0035] S3, the rails to be laid are unlocked on the rail laying machine and separated by the rail splitting mechanism. The rails are then pushed by the dragging and pushing mechanism so that they pass through the guide section of the first rail shifting mechanism and continue to be pushed backward. As the rails are pushed to the next rail shifting mechanism, the guide section of the previous rail shifting mechanism adjusts its position until the rails can pass smoothly through the guide section of the next rail shifting mechanism. Finally, the guide sections of each rail shifting mechanism move to the second preset position. At this time, the rail head is already in the rail bearing groove of the adjacent line.

[0036] At the same time, the rail head of the rail to be laid is connected to the rail tail of the rail being laid through a rail clamping structure;

[0037] S4, the track laying machine moves forward at a constant speed, so that the rail to be laid is unloaded and put into the groove. At this time, the rail head and rail clamping structure of the rail to be laid are also located in the rail bearing groove of the adjacent line.

[0038] S5, disassemble the rail clamping structure and install the rail fasteners at the joint;

[0039] S6, the track-laying unit continues to move forward at a constant speed, continuously unloading multiple rails into the groove on the adjacent line, repeating S5 to complete the track-laying operation on the adjacent line.

[0040] At the same time, such as Figure 2 As shown, in one specific embodiment of this example, the track-laying unit includes a pusher 10 and three rail flatcars 20. Five sets of rail-shifting mechanisms 30 are installed on the three rail flatcars 20, and a counterweight mechanism may also be provided. The high-power pusher 10 drives the laying of long, heavy rails on adjacent lines. The rail flatcars 20 are extended low-flatbed rail flatcars 20, and their bogies can be small-diameter, metro-grade welded bogies with side frames and bolsters. Hydraulic limiters are installed between the bolster and the side frames, used during operation to ensure that the rail flatcars 20 remain parallel to the construction line at all times.

[0041] The five rail-shifting mechanisms 30 are sequentially designated from front to back as Rail-Shifting Mechanism No. 1 to Rail-Shifting Mechanism No. 5. Rail-Shifting Mechanism No. 1 uses two lateral movement cylinders for lateral movement and dragging. These two cylinders are symmetrically installed, one pushing and one pulling to ensure balanced force on the rail guide. It also includes two lifting cylinders to adjust the height of the rail guide, allowing the rail to pass smoothly. These lifting cylinders can be installed on the small crossbeams at the bottom of the rail flatcar 20. Rail-Shifting Mechanisms No. 2 to No. 5 use a rotating and retracting mechanism. The left and right swing of the rail guide is controlled by the extension and retraction of rotating cylinders. Simultaneously, telescopic auxiliary columns are welded to corresponding positions on both sides of the rail flatcar 20. The lifting cylinders drive the lifting and retraction. After the rail guide swings to the corresponding position, the auxiliary column bolts lock in place. The main column and auxiliary columns form a three-point support, resulting in more balanced force distribution.

[0042] Each of the five rail-aligning mechanisms 30 can be equipped with a horizontal sensor. The control cylinder of the rail-aligning guide adjusts the height of the rail-aligning guide based on the horizontal sensor, so that the rail-aligning mechanism 30 can automatically adjust to the rail according to the trajectory line on roads with high curvature.

[0043] As described above, the rapid cross-track laying method provided in this embodiment enables the continuous laying of multiple adjacent rails without the need for repeated rail crossing and alignment during each rail laying. This saves time on adjacent track laying and improves efficiency, which is particularly significant when conducting track laying operations in complex areas. For example, while previous methods could only lay 500m at a time, the method provided in this embodiment can lay over 3000m at a time.

[0044] Please refer to it again. Figure 2 , Figure 3Based on the same inventive concept, this embodiment also provides a rapid cross-line track laying device, including a pusher 10, multiple rail flatcars 20, multiple rail shifting mechanisms 30, and multiple rail clamps 40. The pusher 10 sequentially pulls each rail flatcar 20. The pusher 10 is equipped with a rail splitting mechanism, a dragging and pushing mechanism, etc., enabling the splitting and pushing of the rails to be laid. The rail shifting mechanisms 30 are mounted on corresponding rail flatcars 20. Each rail shifting mechanism 30 is equipped with a rail shifting guide, which guides and shifts the rails, pushing them from the current line to an adjacent line along a preset path.

[0045] The rail clamp 40 is used to clamp and connect the rail being laid and the rail to be laid for continuous rail laying. Simultaneously, as... Figure 4 As shown, the rail clamp 40 includes a clamping base 41, with a clamping opening 42 at its first end, into which the rail web can be inserted. A clamping block 43 is disposed within the clamping base 41, and the clamping block 43 has a clamping surface 44. The clamping block 43 is rotatably connected to the clamping base 41 via a first rotating shaft 45, and the clamping surface 44 is located on the side where the clamping opening 42 is located. Therefore, when the clamping block 43 is subjected to traction force, it can rotate relative to the clamping base 41, allowing the clamping surface 44 to contact the rail web located within the clamping opening 42 and apply compressive force, ensuring the rail is fixed within the clamping opening 42. Furthermore, the clamping surface 44 is also provided with anti-slip textures, which increase friction and ensure a secure rail clamping.

[0046] Meanwhile, a spring-loaded buckle plate 46 is also provided inside the clamping seat 41. The first end of the spring-loaded buckle plate 46 is rotatably connected to the clamping seat 41 via a second rotating shaft 47, and the second end of the spring-loaded buckle plate 46 is connected to a spring 48 (or other elastic element). The other end of the spring 48 is connected to the clamping block 43 at a position away from the clamping surface 44. When the spring-loaded buckle plate 46 rotates around the second rotating shaft 47, the length of the spring 48 tends to change, and the spring 48 provides traction force to drive the clamping block 43 to rotate. Furthermore, when the spring-loaded buckle plate 46 rotates around the second rotating shaft 47, the length of the spring 48 will continuously change, with a position where the elastic force is maximum.

[0047] Since the rail needs to be clamped, relying solely on the spring 48 to maintain the clamping state of the clamping block 43 requires a high stiffness from the spring 48. Therefore, on the one hand, the stiffness coefficient of the spring 48 needs to be set relatively large to maintain the clamping force applied by the clamping block 43 to the rail. On the other hand, in this embodiment, a limiting groove 49 is provided at the second end of the clamping seat 41. The limiting groove 49 starts from the second end of the clamping seat 41 and extends a certain distance towards the first end of the clamping seat 41. At the same time, a connecting rod 410 is provided inside the clamping seat 41. The first end of the connecting rod 410 is rotatably connected to the clamping block 43 at a position away from the clamping surface 44, and the second end of the connecting rod 410 is slidably disposed in the limiting groove 49 through a first limiting pin 411. Meanwhile, the spring 48 is connected to the clamping block 43 near the second end of the connecting rod 410, or directly connected to the second end of the connecting rod 410.

[0048] When using the rail clamp 40 provided in this embodiment, two rail clamps 40 are respectively connected to the ends of two rails. The two rail clamps 40 are connected by a connecting chain 412, and the connecting chain 412 is sleeved in the corresponding first limiting pin 411. During the rail laying operation, the two rails tend to separate from each other. Therefore, the rail clamps 40 connected to the two rails also tend to separate from each other. Under the action of the connecting chain 412, the two first limiting pins 411 slide towards the second end of the clamping seat 41. Under the action of the two first limiting pins 411, the connecting rod 410 pulls the clamping block 43 to rotate clockwise as shown in the figure, further clamping the rails and increasing the clamping force. At this time, the spring 48 also provides the clamping force transmitted to the clamping block 43 and then to the rails. On the one hand, this method can make the clamping effect of the clamping block 43 better, avoiding the need to rely solely on the elastic force of the spring 48 for clamping. At the same time, the spring 48 can provide a locking function, that is, when the two rails do not tend to separate during the installation of the rail clamp 40 or during the laying of rails, the spring 48 ensures that the rail clamp 40 is still clamped.

[0049] Meanwhile, a second limiting pin 413 is also provided inside the clamp 41. The second limiting pin 413 is located on the rotation path of the second end of the spring buckle plate 46. During the process of rotating the spring buckle plate 46 clockwise until it abuts against the second limiting pin 413, the spring 48 is stretched to its maximum length first, and then shortens a small section before it can no longer rotate. At this time, the rail clamp 40 is in a locked state. The spring 48 is stretched when rotated counterclockwise, and it needs to overcome the external force. Therefore, when installing the rail clamp 40, after the rail is inserted into the clamp 42, simply rotate the spring buckle plate 46 clockwise until it contacts the second limiting pin 413. When disassembling, after the two rails are stable, rotate the spring buckle plate 46 counterclockwise. The spring 48 gradually shortens after passing the position of maximum stretch, and the elastic force it provides gradually decreases. At the appropriate position, the clamp 43 no longer provides clamping force on the rail, and the rail can be removed from the clamp 42.

[0050] Therefore, the rail clamp 40 provided in this embodiment adopts a simple and easy-to-operate elastic locking method. Simply moving the spring latch plate 46 keeps the rail clamp 40 in a locked state, and disassembly is also very convenient. The two rail clamps 40 are connected by a connecting chain 412. Further design of the first connecting pin 411 and connecting rod 410 prevents the rail clamps 40 from loosening and disengaging due to back-and-forth movement of the rail. This improves the feasibility, reliability, and convenience of continuous rail laying.

[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
