Description

Technical Field

[0001] The invention relates to the field of ballastless track construction, and in particular to a track plate fine adjuster and method for ballastless track construction. Background Art

[0002] Ballastless track has the advantages of good stability, long service life, good durability, and less maintenance, and is widely used in the construction of high-speed railways. When laying ballastless track, the track plate is laid first, and the self-compacting concrete is poured after the position of the track plate is accurately adjusted. Therefore, during the construction of ballastless track, the position of the track plate of the ballastless track needs to be adjusted using a fine adjuster to ensure the accuracy of the three-dimensional coordinates of the track plate.

[0003] A Chinese patent (publication number: CN 112176792 A) discloses an intelligent fine-tuning system for ballastless track slabs, in which the adjustment heads of the fine-tuning claws are all set in one direction through a steering mechanism, and the output shaft of the reducer inside the adjustment mechanism is set in parallel, so as to facilitate the installation between the adjustment mechanism and the fine-tuning claws. The fine-tuning claws are horizontally distributed as a whole, and the adjustment heads of the fine-tuning claws are in a lateral direction. The longitudinal and lateral positions and elevations of the track slabs are adjusted through a lateral docking adjustment mechanism. In narrow or complex working environments, such as tunnels with narrow spaces, complex terrain areas, and multi-equipment cross-operation areas, the horizontally distributed fine-tuning claws and lateral adjustment heads need to be equipped with horizontally distributed operating tools, and the operating space of the operating tools is limited, which increases the difficulty and complexity of the operation; and it is easy to interfere with other equipment, affecting the operating efficiency and safety between the equipment.

DETAILED DESCRIPTION

[0030] Example 1

[0031] In a typical embodiment of the present invention, Figure 1-Figure 2 As shown, a track plate fine adjuster for ballastless track construction is provided.

[0032] When the fine adjustment tools of the track plate 21 are distributed on the side of the track plate 21, if the fine adjustment tools are operated from the side, they will be affected by the narrow or complex working environment and there will be inconvenience in operation. Based on this, the present embodiment provides a track plate fine adjuster for ballastless track construction, and a three-axis adjustment component is set to drive the fixed plate 11 to adjust the position, thereby driving the track plate 21 to be fine-adjusted. The three-axis adjustment component is provided with a corresponding transmission structure, and the operating end of the adjustment rod for adjusting the horizontal position is adjusted to the top of the fixed plate 11, and combined with the operating end of the vertical screw rod 1 located above, a position that is convenient for operation is provided to improve construction efficiency.

[0033] like Figure 1 As shown, the track plate fine adjuster for ballastless track construction mainly includes a fixed plate 11 and a three-axis adjustment component. The fixed plate 11 can be connected to the track plate 21 and move with the track plate 21. When the position of the fixed plate 11 is adjusted, the position of the connected track plate 21 is adjusted accordingly; the three-axis adjustment component can drive the fixed plate 11 to move in three directions: vertical, horizontal, and longitudinal, to achieve three-axis adjustment of the track plate 21.

[0034] Specifically, the fixing plate 11 is the base of the entire fine tuner, and one side of the fixing plate 11 is provided with a fixing portion connected to the track plate 21, which is used to firmly connect the track plate 21. Figure 2As shown, the fixing part can be provided with corresponding through holes, and fasteners such as bolts and screws can be used to establish the connection between the fixing part and the track plate 21. The fixing plate 11 is provided with threaded holes and guide holes. The threaded holes are used to cooperate with the vertical adjustment elements in the three-axis adjustment assembly, that is, to cooperate with the vertical screw rod 1, and the guide holes are used to cooperate with the lateral adjustment rod 3 and the vertical adjustment rod. The lateral adjustment rod 3 and the vertical adjustment rod are used as transmission structures to adjust the operating positions of the lateral adjustment and the longitudinal adjustment, and transfer them to a position above the fixing plate 11 that is convenient for operation, so as to facilitate the precise adjustment of the track plate 21 in three-dimensional space.

[0035] The three-axis adjustment assembly includes a transverse screw rod 6, a longitudinal screw rod 7, a vertical screw rod 1, a base 8, a longitudinal slider 9 and a transverse slider 10, so as to independently and accurately adjust the position of the track plate 21 in three dimensions (lateral, longitudinal and vertical). Figure 2 As shown, the longitudinal direction refers to the direction extending along the track, the transverse direction refers to the direction perpendicular to the longitudinal direction in the horizontal plane, that is, along the transverse direction of the track, and the vertical direction refers to the vertical direction.

[0036] One end of the transverse screw rod 6 cooperates with the threaded hole at one end of the longitudinal slider 9, and the other end is transmitted with the transverse adjustment rod 3 passing through the guide hole to achieve the transverse adjustment of the track plate 21. One end of the longitudinal screw rod 7 cooperates with the threaded hole set on the guide block 12. The guide block 12 is installed in the guide groove at one end of the base 8. The guide groove is distributed along the direction parallel to the axis of the transverse screw rod 6, restricting the longitudinal movement of the guide block 12 relative to the base 8, and enabling the guide block 12 to slide in the transverse direction. The other end of the longitudinal screw rod 7 is transmitted with the longitudinal adjustment rod 2 passing through the guide hole to control the longitudinal position adjustment of the track plate 21. One end of the vertical screw rod 1 is connected to the top surface of the transverse slider 10, and the other end passes through the threaded hole on the fixed plate 11, which is used to adjust the height of the track plate 21 in the vertical direction.

[0037] The top ends of the transverse adjustment rod 3, the longitudinal adjustment rod 2 and the vertical screw rod 1 are all located on the fixed plate 11, and serve as the operating end for external adjustment tools such as an electric wrench, so that the operating end is arranged above the fixed plate 11, which is convenient for operation from the top, especially for the situation where it is inconvenient to operate in the narrow space on the side. This not only reduces interference with other equipment, but also improves the efficiency of collaborative work between equipment.

[0038] In order to facilitate accurate and efficient operation with the tool, the operating end can adopt the following structure:

[0039] Hexagonal head: The operating end is designed in a hexagonal shape, which matches common tools such as hexagonal wrenches or hexagonal sockets. This design can provide a stable connection and transmit a large torque, and is suitable for adjustment occasions that require a large torque.

[0040] Square Head: Similarly, the square head design can also be used with tools such as square wrenches to provide stable grip and torque transfer.

[0041] Standard thread: The operating end can be designed with a standard thread interface, such as M series or UNC / UNF series threads. In this way, the operator can use a nut, wrench or clamp that matches the thread interface to perform the operation, which improves the flexibility and compatibility of the operation.

[0042] Quick chuck: Install quick chuck or quick connection device on the operating end, such as quick wrench chuck, magnetic table holder, etc. These devices can be easily connected and disconnected with various tools, improving work efficiency and convenience of operation.

[0043] Slot: A slot or slot with a specific shape is designed on the operating end to cooperate with special tools (such as wrenches or clamps with plugs). This design can ensure accurate alignment and stable connection between the tool and the operating end.

[0044] Standardized connectors: Follow international or industry standardization specifications to design operating end interfaces with uniform sizes and specifications. This ensures compatibility with widely available tools on the market, reducing procurement and use costs.

[0045] Anti-skid materials or anti-skid patterns may also be used on the surface of the operating end to increase stability and safety when holding, and clear indicator marks or scale lines may be set on the operating end to facilitate the operator to understand the current position and the direction that needs to be adjusted.

[0046] Traditional track plate 21 fine-adjustment equipment often needs to be operated on the side of the track plate 21, which is extremely inconvenient when the side space is small. The track plate fine-adjuster for ballastless track construction in this embodiment solves this problem by arranging the operating end at the top, making the operation more flexible and convenient. In a complex construction environment, interference between equipment is a common problem. The track plate fine-adjuster for ballastless track construction in this embodiment reduces interference with other equipment and improves construction efficiency through reasonable layout and structural design. When traditional fine-adjustment equipment works in coordination, it is often inefficient due to inconvenient operation or interference between equipment. The track plate fine-adjuster for ballastless track construction in this embodiment improves the efficiency of collaborative work between equipment through optimized design and top operation mode.

[0047] like Figure 1As shown, in order to meet the requirements of arranging the longitudinal slider 9 and cooperating with the longitudinal screw rod 7, the base 8 includes a horizontal section and a vertical section, which are connected to form an L-shaped structure. The longitudinal slider 9 is slidably matched on the horizontal section, and a lower pressing plate 15 is provided at the bottom of the longitudinal slider 9. The lower pressing plate 15 can be combined with the longitudinal slider 9 to form a slide groove to match the horizontal section of the base 8, maintain the relative position of the base 8 and the longitudinal slider 9, and prevent the longitudinal slider 9 from detaching from the base 8, so as to form a stable force transmission. A guide groove plate 17 is provided at the top of the vertical section. The two guide groove plates 17 are arranged at a relative interval and form a guide groove for matching the guide block 12 therebetween. The guide block 12 slides along the guide groove, and the sliding direction is parallel to the axis of the transverse screw rod 6. The threaded hole on the guide block 12 is a threaded through hole, and the longitudinal screw rod 7 is provided with a thread on the outside. After the longitudinal screw rod 7 is matched with the threaded hole on the guide block 12, the longitudinal screw rod 7 can change its relative position with the base 8 by rotating the longitudinal screw rod 7.

[0048] The L-shaped design enables the base 8 to stably support the entire three-axis adjustment assembly and provide sufficient space for the longitudinal slider 9 to slide thereon. At the same time, the guide plate 17 and the guide block 12 provided on the vertical section form a sliding structure, and the threaded hole on the guide block 12 allows the longitudinal screw rod 7 to pass through and cooperate with it to achieve longitudinal adjustment. The structural stability and bearing capacity of the base 8 are enhanced, and the accuracy and stability of the longitudinal adjustment are ensured.

[0049] The longitudinal slider 9 includes a transverse section and a vertical section, which are connected to form an L-shaped structure. The transverse slider 10 is slidably fitted on the transverse section, and the vertical section is provided with a threaded hole that cooperates with the transverse screw rod 6. Figure 1 As shown, a guide plate 16 is provided on the transverse section, and the guide plate 16 can form a slide groove structure in combination with the longitudinal slider 9, and the slide groove structure forms a sliding fit with the transverse slider 10. The guide plate 16 is located on the top surface of the transverse section of the longitudinal slider 9, and the lower pressure plate 15 is located on the bottom surface of the transverse section of the longitudinal slider 9. The transverse screw rod 6 is provided with threads on the outside. After the transverse screw rod 6 is matched with the threaded hole, the transverse screw rod 6 can be rotated to change the relative position with the longitudinal slider 9. The L-shaped design enables the longitudinal slider 9 to support the transverse slider 10 while also being able to cooperate with the transverse screw rod 6 through its vertical section to achieve transverse adjustment. The functionality and structural strength of the longitudinal slider 9 are improved, ensuring the smooth progress of transverse adjustment.

[0050] The transverse screw rod 6 and the longitudinal screw rod 7 adjust the position of the fixing plate 11 by rotating. In order to make the operation of the transverse screw rod 6 and the longitudinal screw rod 7 more stable, a plurality of sliding holes are provided on the transverse slider 10, which are respectively used for the sliding cooperation of the segments between the longitudinal screw rod 7 and the two ends of the transverse screw rod 6. The sliding hole design enables the segments between the two ends of the screw rod to slide smoothly in the sliding hole when the screw rod is rotated for adjustment, avoiding poor adjustment caused by bending or jamming of the screw rod. The stability and reliability of the screw rod transmission are improved, and the accuracy of adjustment is ensured.

[0051] The vertical screw rod 1 is installed on the top surface of the horizontal slider 10 through a ball joint to ensure that the axis of the vertical screw rod 1, the axis of the horizontal screw rod 6 and the axis of the longitudinal screw rod 7 are perpendicular to each other. The ball joint installation allows the vertical screw rod 1 to have a certain degree of freedom during the adjustment process to adapt to slight deviations in different directions while maintaining the vertical relationship between the three axes. The flexibility and adaptability of vertical adjustment are enhanced, and the accuracy and stability of the overall adjustment are improved.

[0052] like Figure 1 As shown, in order to realize the transmission between the transverse screw rod and the transverse adjustment rod 3, and the transmission between the longitudinal screw rod 7 and the longitudinal adjustment rod 2, one end of the transverse screw rod 6 is connected to the transverse adjustment rod 3 through the transverse deflector 5, the transverse adapter 5 is installed on the transverse slider 10 through the transverse support plate 18, and the transverse screw rod 6 and the transverse adjustment rod 3 are transmitted through a bevel gear; one end of the longitudinal screw rod 7 is connected to the longitudinal adjustment rod 2 through the longitudinal deflector 4, the longitudinal adapter 4 is installed on the transverse slider 10 through the longitudinal support plate 19, and the longitudinal screw rod 7 and the longitudinal adjustment rod 2 are transmitted through a bevel gear.

[0053] Among them, one end of the transverse screw rod 6 is connected to a bevel gear, and one end of the transverse adjustment rod 3 is connected to a bevel gear. The two bevel gears are meshed, so that torque is transmitted between the transverse screw rod 6 and the transverse adjustment rod 3. A protective shell can also be installed outside the meshing position. The protective shell and the bevel gear together form a transverse deflector 4. The bevel gear is located in the protective shell, and the transverse screw rod 6 passes through one side wall of the protective shell and probes into the protective shell, and the transverse adjustment rod 3 passes through the other side wall of the protective shell and probes into the protective shell. The protective shell can maintain the relative horizontal position and longitudinal position between the transverse screw rod 6 and the transverse transmission rod, so that when the transverse screw rod 6 moves relative to the longitudinal slider 9, it can drive the transverse transmission rod to move synchronously, thereby driving the fixed plate 11 to move, and then driving the transverse slider 10 to move.

[0054] One end of the longitudinal screw rod 7 is connected to a bevel gear, and one end of the longitudinal adjustment rod 2 is connected to a bevel gear. The two bevel gears are meshed with each other, so that torque is transmitted between the longitudinal screw rod 7 and the longitudinal adjustment rod 2. A protective shell can also be installed outside the meshing position. The protective shell and the bevel gear together form a longitudinal steering gear 4. The bevel gear is located in the protective shell, and the longitudinal screw rod 7 passes through one side wall of the protective shell and probes into the protective shell, and the longitudinal adjustment rod 2 passes through the other side wall of the protective shell and probes into the protective shell. The protective shell can maintain the relative horizontal position and longitudinal position between the longitudinal screw rod 7 and the longitudinal transmission rod, so that when the longitudinal screw rod 7 moves relative to the base 8, it can drive the longitudinal transmission rod to move synchronously, thereby driving the fixed plate 11 to move, and then driving the transverse slider 10 to move.

[0055] The bevel gear transmission can convert the rotational motion of the longitudinal screw rod 7 around its horizontal axis into the rotational motion of the longitudinal adjustment rod 2 around the vertical axis. When the longitudinal adjustment rod 2 is driven by an external force, the torque can be transmitted to the longitudinal screw rod 7, so that the operator can achieve precise control of the longitudinal screw rod 7 by rotating the longitudinal adjustment rod 2 above the fixed plate 11. The bevel gear transmission can convert the rotational motion of the transverse screw rod 6 around its horizontal axis into the rotational motion of the transverse adjustment rod 3 around the vertical axis. When the transverse adjustment rod 3 is driven by an external force, the torque can be transmitted to the transverse screw rod 6, so that the operator can achieve precise control of the transverse screw rod 6 by rotating the transverse adjustment rod 3 above the fixed plate 11. The operation process is simplified and the convenience and accuracy of adjustment are improved.

[0056] The lateral adjustment rod 3, the longitudinal adjustment rod 2 and the vertical screw rod 1 are arranged in parallel, and an operating end is formed at one end above the fixed plate 11. The parallel arrangement and the operating end design allow the operator to conveniently control and operate the adjustment in three directions from the top, and ensure the relative position between the three axes and the accuracy of the three-axis adjustment.

[0057] like Figure 1 and Figure 2 As shown, the base 8 is provided with a mounting portion, which is hinged to the support plate 13, and the hinge position uses a pin 14 as a rotation axis. The support plate 13 can be connected to the external bottom plate 20, and the transverse slider 10 follows the longitudinal slider 9 to slide along the base 8, and the guide block 12 follows the transverse slider 10 to move relative to the longitudinal slider 9. The support plate 13 allows the entire fine adjuster to be stably mounted on the external bottom plate 20, ensuring stability and safety during the adjustment process.

[0058] In actual operation, the transverse slider 10 follows the longitudinal slider 9 to slide along the base 8. Similarly, the fixing plate 11 can drive the transverse slider 10 to move relative to the longitudinal slider 9. In this embodiment, the relative sliding between the transverse slider 10, the longitudinal slider 9 and the base 8 can be achieved by the following structure:

[0059] The slide rails cooperate with the sliders, and the slide rails are respectively designed on the horizontal section of the base 8 and the transverse section of the longitudinal slider 9. Correspondingly, sliders that cooperate with the slide rails are designed on the longitudinal slider 9 and the transverse slider 10. The sliders can be made of wear-resistant materials to ensure a low friction coefficient and a long service life during the sliding process.

[0060] The screw drive and guide, the longitudinal screw 7 and the transverse screw 6 are respectively connected to the threaded holes of the guide block 12 and the longitudinal slider 9 of the base 8 through threads. When the screw rotates, due to the meshing action of the threads, the corresponding slider will be driven to slide on the slide rail. In addition to the driving effect of the screw, the cooperation between the slide rail and the slider also plays a guiding role to ensure that the slider maintains the correct direction and trajectory during the sliding process.

[0061] In order to prevent the slider from exceeding the predetermined range during the sliding process, limit devices such as limit blocks or limit pins can be set at both ends of the slide rail. In order to reduce the friction resistance during the sliding process, a lubrication system can be set between the slide rail and the slider, such as applying lubricating oil or installing a lubricating sheet. Under the premise of ensuring structural strength and stability, lightweight materials should be used as much as possible to reduce the weight of the entire fine tuner and improve construction efficiency. The base 8, slider, screw rod and other components are designed as a modular structure for easy disassembly, installation and maintenance. Key components such as slide rails, sliders and screw rods are processed with high precision to ensure matching accuracy and transmission accuracy. When necessary, a fine-tuning mechanism such as a fine-tuning screw or a fine-tuning handle can be set to fine-tune the position of the slider.

[0063] In another typical embodiment of the present invention, Figure 1-Figure 2 As shown, a working method of a track slab fine adjuster for ballastless track construction is provided, using the track slab fine adjuster for ballastless track construction as in Example 1.

[0064] The base 8 is installed on the top surface of the bottom plate 20, and the fixing plate 11 is installed on the side of the track plate 21, so that the top ends of the longitudinal adjustment rod 2, the transverse adjustment rod 3 and the vertical screw rod 1 are located above the fixing plate 11;

[0065] By adjusting the longitudinal adjustment rod 2, the longitudinal screw rod 7 is driven to rotate relative to the base 8, and the fixed plate 11, the longitudinal slider 9 and the transverse slider 10 are driven to move longitudinally relative to the base 8 to adjust the longitudinal position of the track plate 21;

[0066] By adjusting the transverse adjustment rod 3, the transverse screw rod 6 is driven to rotate relative to the longitudinal slider 9, and the fixed plate 11, the transverse slider 10, and the guide block 12 are driven to move in the transverse direction relative to the longitudinal slider 9 to adjust the transverse position of the track plate 21;

[0067] The vertical screw rod 1 is adjusted to rotate relative to the fixed plate 11 , thereby driving the fixed plate 11 to rise and fall relative to the transverse slider 10 , thereby adjusting the vertical position of the track plate 21 .

[0068] When the vertical position of the fixing plate 11 is adjusted, the fixing plate 11 is lifted or lowered relative to the longitudinal adjustment rod 2 and the transverse adjustment rod 3 , and the guide holes constrain the horizontal positions of the longitudinal adjustment rod 2 and the transverse adjustment rod 3 .

[0069] The lateral steering gear 5 and the longitudinal steering gear 4 are used to adjust the operating ends of the driving lateral screw rod 6 and the longitudinal screw rod 7 to the top of the fixed plate 11. In order to adapt to the lifting and lowering action of the fixed plate 11 driven by the vertical screw rod 1, a sliding fit is formed between the lateral adjustment rod 3 and the fixed plate 11, and a sliding fit is formed between the longitudinal adjustment rod 2 and the fixed plate 11. The positions of the lateral adjustment rod 3 and the longitudinal adjustment rod 2 are maintained during the lifting process to meet the operational requirements during adjustment.
