Description

Technical Field

[0001] The invention belongs to the technical field of sleeper surface treatment in rail transportation engineering, and particularly relates to a water retaining structure for sleeper water jet treatment equipment. Background Art

[0002] Bi-block ballastless track is a modern track structure that replaces traditional crushed stone ballast with a monolithic concrete ballast. Its core load-bearing unit is a bi-block concrete sleeper embedded within the ballast. These sleepers consist of two separate concrete blocks connected by a steel truss, precisely securing the rails in place. Over long-term service, the connection between the sleepers and the slab is prone to 45° diagonal cracks and microcracks. The root cause is insufficient adhesion between the secondary poured slab concrete and the smooth surface of the sleepers, resulting in microscopic water seepage channels at the interface.

[0003] To solve this problem, the industry has focused on the technical approach of "enhancing the bonding strength between new and old concrete by roughening the sleeper surface". This has led to the demand for a water retaining structure for sleeper water jet treatment equipment - this structure is needed to assist the high-pressure water jet process and accurately roughen the surface of a certain range below the top surface of the sleeper to improve the bonding effect between new and old concrete.

[0004] To achieve effective roughening of the sleeper surface, the current mainstream process uses a customized water retaining cover to cover the non-treated area on the top of the sleeper. However, since double-block sleepers not only have significant differences in length, extending from the standard 2.4m to the extended 3.2m specifically for the switch area, but also have multiple dimensional variations in width to accommodate different track load requirements, each specification of sleeper requires a matching customized water retaining cover. However, this one-to-one customization model has adaptation defects in multiple links: the design needs to be verified separately for each specification, resulting in duplicate costs; manufacturing requires separate mold processing, and small batches drive up unit costs; the production line requires dozens of tooling, which is complex to store and manage, and is prone to production stoppages due to confusion or omissions. New specifications continue to increase costs, forming an unmanageable burden. Summary of the Invention

[0005] The purpose of the present invention is to provide a water retaining structure for a water jet treatment device for sleepers, so as to solve the problems in the prior art of poor adaptability to sleepers of different widths and thicknesses, inaccurate water retaining positioning resulting in loss of control of the water jet treatment range and cumbersome operation, and facilitate precise control of the high-pressure water jet to perform roughening treatment on a certain range below the top surface of the sleeper, thereby improving treatment efficiency and consistency.

[0006] To achieve the above object, the present invention provides the following technical solutions: A water retaining structure for a sleeper water jet treatment device, comprising: Two symmetrically arranged installation boxes, a protective cover is installed between the two installation boxes, a jet component is installed inside the installation box, a sleeper conveying component is installed just below the protective cover, and a water retaining mechanism is installed above the conveying component; The water retaining mechanism includes two water retaining plates arranged along the length direction of the sleeper conveying component. The two water retaining plates are symmetrically arranged, and a limited height component is provided on the opposite side, and an elastic clamping component is provided on the opposite side. Arc-shaped guide plates are symmetrically fixed at both ends of the water retaining plate, and both sides of the top are connected to a hanging plate through an adjustment component. The top of the hanging plate is fixed on the protective cover through a telescopic component.

[0007] Preferably, the adjustment component includes a linear guide rail arranged along a direction perpendicular to the length direction of the sleeper conveying component, the top end of the linear guide rail is fixedly set on the hanging plate, and sliders are slidably installed on both sides of the bottom end, and the bottom ends of the sliders are connected to an inverted U-shaped hanging frame through an adapter component, and a rotating shaft is rotatably installed at the bottom end of the hanging frame. Active grooves are penetrated on both sides of the top of the water baffle, and two rotating shafts of different adjustment components located on the same longitudinal axis of the sleeper conveying component vertically penetrate the corresponding active grooves, and the rotating shafts are slidably set in the active grooves.

[0008] Preferably, the adapter assembly includes a U-shaped adapter frame fixedly arranged at the bottom end of the slider, a adapter shaft is rotatably mounted on the center of the bottom surface of the adapter frame, and the other end of the adapter shaft is rotatably mounted on the top surface of the hanging frame.

[0009] Preferably, the elastic clamping assembly includes multiple groups of elastic components that are evenly distributed along the length direction of the sleeper conveying component and arranged up and down, and the elastic component includes a support rod fixedly arranged on the inner wall of the protective cover, and a compression spring is fixedly arranged on the end of the support rod away from the inner wall, and a ball head seat is fixedly arranged on the end of the compression spring away from the support rod, and the ball head seat is movably abutted against the side wall of the baffle.

[0010] Preferably, the height limiting component includes a positioning plate fixedly arranged on the side wall of the water baffle, and arc-shaped guide slopes are provided on both sides of the bottom end of the positioning plate. An installation groove is opened on the side wall near the bottom end, and multiple groups of sliding contact components are assembled in the installation groove.

[0011] Preferably, the sliding contact assembly includes a bearing fixedly arranged on the side wall of the installation groove, the inner ring of the bearing is fixedly provided with a connecting shaft, and the outer periphery of the connecting shaft is fixedly sleeved with a roller.

[0012] Preferably, a plurality of counterweights are fixedly provided on opposite sides of the two water retaining plates.

[0013] Preferably, the telescopic assembly includes a plurality of evenly distributed damping telescopic rods, the top ends of the plurality of damping telescopic rods are fixedly arranged on the inner top surface of the protective cover, and the bottom ends are fixedly arranged on the top surface of the hanging plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects: (1) Two symmetrically arranged water retaining plates are used as the core water retaining components. Together with the arc-shaped guide plates at both ends, rail sleepers of different widths can be guided to squeeze smoothly between the two plates, avoiding damage to the rail sleepers or equipment jamming caused by rigid collisions. The height limiting components on the opposite sides cooperate with the elastic pressing components on the opposite sides. The elastic pressing components push the water retaining plates to fit the side of the rail sleepers through continuous elastic force, ensuring that the water retaining gap is minimized and preventing the water jet from splashing into non-treated areas. The adjustment component and the telescopic component at the top form a composite limiting mechanism, ensuring that the jet component only processes a certain range below the top surface of the rail sleeper. Compared with the water retaining method in the existing technology that requires manual adjustment, this structure can adapt to rail sleepers of different specifications without additional operation, greatly improving the processing efficiency. At the same time, the boundary accuracy of the roughening treatment is guaranteed by precise water retaining, effectively solving the problems of poor adaptability and uncontrolled processing range in the existing solution.

[0015] (2) The arc-shaped guide slope at the bottom of the positioning plate in the height-limiting component can smoothly convert the linear motion of the sleeper into an upward thrust on the water retaining plate. In conjunction with the precise positioning of the sliding contact component, the water retaining plate can adaptively adjust its height as the thickness of the sleeper changes, ensuring that the vertical distance between its bottom and the top surface of the sleeper is always a fixed value, effectively covering sleeper specifications with thickness differences of up to 100mm. The counterweight block provides reset power for the water retaining plate through gravity. Combined with the "upper and lower layer settings" of the elastic pressing component and the deflection characteristics of the ball head seat, it not only ensures the tight fit of the upper elastic component when thick sleepers are processed, but also allows the water retaining plate to smoothly pass through the lower elastic component when resetting, avoiding jamming. Compared with the fixed height water retaining structure in the existing technology that is not compatible with sleepers of different thicknesses and requires frequent manual adjustment, this structure realizes fully automatic adjustment of "different sleeper thicknesses". It can ensure the precise exposure of the treated areas of different sleeper thicknesses and the reliable shielding of the non-treated areas without additional operation, greatly improving the versatility and processing consistency of the equipment and extending the service life of the components.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] In the description of the present invention, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inside," "outside," and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be construed as limiting the present invention. In the description of the present invention, unless otherwise specified, "plurality" means two or more. Example 1:

[0019] See also Figures 1-8 As shown, a water retaining structure for a sleeper water jet treatment device comprises: Two symmetrically arranged installation boxes 1, a protective cover 2 is installed between the two installation boxes 1, a jet component 3 is installed inside the installation box 1, a sleeper conveying component 4 is installed just below the protective cover 2, and a water retaining mechanism is installed above the conveying component; The water retaining mechanism includes two water retaining plates 5 arranged along the length direction of the sleeper conveying component 4. The two water retaining plates 5 are symmetrically arranged, and a limited height component 7 is provided on the opposite side, and an elastic clamping component 8 is provided on the opposite side. Arc-shaped guide plates 6 are symmetrically fixed at both ends of the water retaining plate 5, and both sides of the top are connected to a hanging plate 11 through an adjustment component 9. The top of the hanging plate 11 is fixed on the protective cover 2 through a telescopic component 10.

[0020] Depend on Figure 3-Figure 5 It can be seen that the elastic clamping assembly 8 includes multiple groups of elastic components that are evenly distributed along the length direction of the sleeper conveying component 4 and arranged up and down. The elastic component includes a support rod 81 fixedly arranged on the inner wall of the protective cover 2, and a compression spring 82 is fixedly arranged at one end of the support rod 81 away from the inner wall. A ball head seat 83 is fixedly arranged at one end of the compression spring 82 away from the support rod 81, and the ball head seat 83 is movably abutted against the side wall of the baffle.

[0021] As can be seen from the above, the core goal of this structure is to assist the jet component 3 in accurately roughening the surface of a certain range below the top surface of the sleeper. Assuming that the range below 20mm on the top surface of the sleeper is the target area that needs to be roughened, the water retaining mechanism needs to form a targeted and reliable covering protection for the non-target area above 20mm on the top surface of the sleeper - by presetting the bottom surface of the water retaining plate 5 at a height position of 20mm below the top surface of the sleeper (i.e., the boundary of the target area), a precise boundary control of "the treated area (below 20mm) is exposed and the non-treated area (above 20mm) is shielded" is formed. When the sleeper conveying component 4 drives the sleeper into the protective cover 2, the two sides of the sleeper will first contact the arc-shaped guide plates 6 at both ends of the water retaining plate 5: Since the two arc-shaped guide plates 6 on the entrance side are open in an eight-shaped design, their arc-shaped surfaces can form a "progressive guide" for the sleeper, which not only avoids a hard collision between the sleeper and the water retaining plate 5, but also guides the sleeper to squeeze smoothly between the two water retaining plates 5, greatly reducing the risk of jamming during sleeper transportation; It should be noted that the 20mm shielding area on the top surface of the sleeper can be adjusted according to subsequent standards and is not a final limitation. Those skilled in the art can make adaptive adjustments based on subsequent requirements for the height of the shielding area.

[0022] When the sleeper is completely squeezed between the two water baffles 5, the elastic compression assembly 8 begins to work: the support rod 81 on the inner wall of the protective cover 2 provides fixed support for the structure, and the compression spring 82 at its end pushes the ball head seat 83 against the side wall of the water baffle 5 through continuous elastic force, so that the two water baffles 5 always fit the surfaces on both sides of the sleeper - the spherical structure of the ball head seat 83 can reduce the contact friction with the water baffle 5, ensuring that the water baffle 5 can flexibly fine-tune its position when squeezed by the sleeper, while ensuring uniform fitting pressure and avoiding water jet splashing caused by local gaps. At the same time, the adjustment assembly 9 and the telescopic assembly 10 jointly ensure the position stability of the water baffle 5.

[0023] In summary, this structure achieves compatibility and adaptation to sleepers of different widths through the smooth guidance of the arc-shaped guide plate 6, the adaptive fit of the elastic clamping component 8, the flexible adaptation of the adjustment component 9 and the precise limitation of the telescopic component 10. It not only ensures the reliable shielding of the non-treated area of ​​the sleeper and prevents the high-pressure water jet from damaging the non-treated surface, but also ensures the complete exposure of the treated area of ​​the sleeper, provides stable boundary conditions for the precise roughening treatment of the jet component 3, and effectively improves the consistency and reliability of the sleeper surface treatment.

[0024] For details about the above, refer to Figure 6 As shown, the adjustment assembly 9 includes a linear guide rail 91 arranged perpendicular to the length direction of the sleeper conveying component 4, the top of the linear guide rail 91 is fixedly set on the hanging plate 11, and sliders 92 are slidably installed on both sides of the bottom end, and the bottom ends of the sliders 92 are connected to an inverted U-shaped hanging frame 95 through an adapter assembly. A rotating shaft 96 is rotatably installed at the bottom end of the hanging frame 95, and a penetrating movable groove 97 is opened on both sides of the top of the water baffle 5. The two rotating shafts 96 of different adjustment assemblies 9 located on the same longitudinal axis of the sleeper conveying component 4 vertically penetrate the corresponding movable groove 97, and the rotating shaft 96 is slidably set in the movable groove 97; The adapter assembly includes a U-shaped adapter frame 93 fixedly set at the bottom end of the slider 92. A adapter shaft 94 is rotatably mounted on the center of the bottom surface of the adapter frame 93, and the other end of the adapter shaft 94 is rotatably mounted on the top surface of the hanging frame 95.

[0025] As can be seen from the above, when the sleeper enters between the two water baffles 5 under the drive of the sleeper conveying component 4, due to the linear progressive entry of the sleeper, its front end first contacts the water baffle 5 on the inlet side of the protective cover 2, resulting in the two water baffles 5 forming a gradual state of "wide spacing on the inlet side and narrow spacing on the outlet side". At this time, although the water baffle 5 can slide on the linear guide rail 91 perpendicular to the sleeper conveying direction via the slider 92 to adapt to the width of the sleeper, it is easy to produce a slight tilt due to the unilateral squeezing of the sleeper (i.e., the side near the inlet has a slightly larger outward opening angle, and the side near the outlet has a smaller angle). If the structure is rigidly connected, this tilt will cause lateral stress to be generated between the slider 92 and the guide rail, causing jamming and even component wear.

[0026] To solve this problem, this structure achieves flexible adaptation through multi-dimensional coordination: the movable groove 97 opened at the top of the water baffle 5 forms a "sliding-rotation" composite connection with the rotating shaft 96. When the water baffle 5 is squeezed on one side, the length of the movable groove 97 reserves sufficient displacement space, allowing the water baffle 5 to rotate at a small angle with the rotating shaft 96 on the other side as a fulcrum, avoiding structural stress concentration due to rigid conflict; at the same time, the adapter shaft 94 in the adapter assembly connects the hanging frame 95 and the U-shaped adapter frame 93 into a rotatable structure, so that the rotating shaft 96 itself can deflect synchronously with the inclination of the water baffle 5, further eliminating the lateral stress - this dual adjustment of "water baffle 5 rotation + rotating shaft 96 deflection" converts the lateral force on the slider 92 into a positive driving force along the guide rail direction, ensuring that the slider 92 can slide smoothly along the linear guide rail 91 without getting stuck due to angle deviation.

[0027] In addition, the matching clearance between the movable groove 97 and the rotating shaft 96 has been precisely designed, which not only ensures the flexibility of the water baffle 5 during rotation, but also avoids the water baffle 5 from shaking due to excessive clearance, ensuring that the vertical distance between its bottom surface and the top surface of the sleeper remains unchanged; and the rotating connection between the adapter shaft 94 and the hanging frame 95 and the adapter frame 93 adopts a self-lubricating design, which can reduce friction loss during long-term use and improve the durability of the structure.

[0028] This composite structure of "rigid guidance + flexible adjustment" effectively avoids the chain problem of "tilting-stuck-wear" in traditional rigid connections, allowing the water retaining plate 5 to maintain smooth movement under different rail sleeper widths and different conveying speeds, providing a structural basis for the accuracy of subsequent water jet processing. Example 2:

[0029] refer to Figure 4 and Figure 8 As shown, the height limiting assembly 7 includes a positioning plate 71 fixedly arranged on the side wall of the water retaining plate 5, and arc-shaped guide slopes 72 are provided on both sides of the bottom end of the positioning plate 71. A mounting groove 73 is provided on the side wall near the bottom end, and multiple groups of sliding contact assemblies are assembled in the mounting groove 73; A plurality of counterweights 12 are fixedly provided on opposite sides of the two water retaining plates 5 .

[0030] As can be seen from the above, the thickness of the sleepers of the bi-block ballastless track needs to be dynamically adapted to the needs of different scenarios. In actual applications, the thickness of different sleepers can vary by up to 100mm. If the height of the water retaining plate 5 is fixed, the vertical distance between its bottom end and the top surface of the sleeper will not be able to remain constant, which will directly affect the accuracy of the water jet treatment. To this end, this structure realizes adaptive adaptation to sleepers of different thicknesses through the collaborative design of multiple components. The coordination logic of each component is as follows: The counterweight 12, as the core reset component, provides a continuous downward pull to the water retaining plate 5 through its own gravity, so that it is always in the lowest initial position when not in contact with the sleeper. This initial position is preset to "the vertical distance between the bottom end of the water retaining plate 5 and the top surface of the thinnest sleeper is 20mm", which reserves space for upward adjustment to accommodate thicker sleepers. This design ensures that no matter how the sleeper thickness changes, the water retaining plate 5 can achieve high self-adaptation by pushing against the sleeper with the "lowest position" as the reference, avoiding the thin sleeper treatment area being blocked due to the initial position being too high, or the thick sleeper being unable to enter due to the initial position being too low.

[0031] When the sleeper enters the protective cover 2, its front edge will first contact the arc-shaped guide slopes 72 on both sides of the bottom end of the positioning plate 71: the arc-shaped guide slopes 72 adopt a quarter-circle arc design, which smoothly converts the linear forward motion of the sleeper into a vertical upward thrust on the positioning plate 71 - the quarter-circle arc makes the contact point gradually transition from the bottom of the front end of the sleeper to the top of the side, forming a "zero impact" progressive push, which not only avoids damage to the corners of the sleeper and the positioning plate 71 due to rigid collision, but also enables the water retaining plate 5 to smoothly adjust its height as the positioning plate 71 slowly rises. As the sleeper continues to move forward, the lifting force increases evenly along the curved surface until the sliding contact assembly (roller 76) on the side wall of the positioning plate 71 contacts the top surface of the side edge of the sleeper. At this time, the distance between the lowest point of the roller 76 and the bottom end of the water baffle 5 is exactly 20 mm. Through the fitting limit of the sliding contact assembly and the top surface of the sleeper, the height of the water baffle 5 is precisely locked to ensure that the vertical distance between its bottom end and the top surface of the sleeper is stable at 20 mm, realizing precise control of "the thicker the sleeper, the higher the water baffle 5 is lifted, but the relative spacing remains unchanged".

[0032] When the rail sleeper completes the jet treatment and moves out of the protective cover 2 along with the conveying component, the water baffle 5 loses the support force of the rail sleeper. At this time, the gravity of the counterweight block 12 is greater than the lateral pressure of the elastic pressing assembly 8, driving the water baffle 5 to fall back to the initial position in the vertical direction. It should be noted that the elastic pressing assembly 8 uses elastic components arranged in upper and lower layers (evenly distributed along the conveying direction of the rail sleeper and arranged up and down): when the water baffle 5 is supported and moved upward by the thick rail sleeper, it only contacts the upper elastic component and is tightly fitted with the side of the thick rail sleeper through the elastic force of the upper pressing spring 82; and during the reset process, the water baffle 5 needs to move down from the fitting position of the upper elastic component and pass through the lower elastic component in sequence.

[0033] During this process, the structural design of the ball head seat 83 plays a key role in avoidance: its spherical surface is in point contact with the side wall of the water retaining plate 5, with a small contact area and extremely low friction resistance. When the water retaining plate 5 moves down through the lower elastic component, the ball head seat 83 can flexibly deflect in the direction of movement of the water retaining plate 5, and will not form a rigid obstruction due to the lateral thrust of the lower compression spring 82. This "upper layer fit, lower layer avoidance" matching mechanism not only ensures the reliable compression of the upper elastic component when handling thick sleepers, but also, through the deflection characteristics of the ball head seat 83, allows the water retaining plate 5 to smoothly pass through the lower elastic component during the reset process, completely avoiding the "stuck risk" caused by the layered setting, and ensuring that the water retaining plate 5 accurately falls back to its initial position under the action of gravity without getting stuck or tilted.

[0034] In summary, the gravity reset of the counterweight 12, the progressive push of the arc-shaped guide slope 72, the precise positioning of the sliding contact assembly and the low resistance of the ball head seat 83 form a complete set of "adaptive height adjustment mechanism": it not only solves the compatibility problem of sleepers with a thickness difference of 100mm, but also ensures that the vertical distance between the bottom end of the water retaining plate 5 and the top surface of the sleeper remains unchanged through the coordinated action of various components, while avoiding impact, jamming and wear during the adjustment process. Compared with the traditional fixed-height water retaining structure, this design significantly improves the adaptability of the equipment to sleepers of different specifications, and does not require manual adjustment of parameters, greatly improving processing efficiency and stability, highlighting the creativity of the structural design.

[0035] Preferably, reference Figure 7 As shown, the sliding contact assembly includes a bearing 74 fixedly arranged on the side wall of the installation groove 73, the inner ring of the bearing 74 is fixedly provided with a connecting shaft 75, and the outer periphery of the connecting shaft 75 is fixedly sleeved with a roller 76.

[0036] As can be seen from the above, the roller 76 is rotatably mounted on the bottom surface of the positioning plate 71 through the connecting shaft 75 and the bearing 74. When the sleeper continues to move in the linear direction, the bottom surface of the positioning plate 71 and the top surface of the sleeper need to remain in contact to ensure the precise positioning of the water retaining structure. The setting of the roller 76 can convert the hard sliding friction between the two into rolling contact, significantly reducing the friction resistance, effectively avoiding scratches and wear on the sleeper surface caused by continuous friction, and at the same time reducing the wear loss at the bottom end of the positioning plate 71, thereby extending the service life of the structure.

[0037] Preferably, reference Figure 3 and Figure 4 As shown, the telescopic assembly 10 includes a plurality of evenly distributed damping telescopic rods 101 , the top ends of which are fixedly arranged on the inner top surface of the protective cover 2 , and the bottom ends of which are fixedly arranged on the top surface of the hanging plate 11 .

[0038] From the above, it can be seen that on the one hand, the damping telescopic rod 101 uses its own rigid telescopic guiding characteristics to strictly limit the displacement direction of the hanger 11, so that it can only move linearly in the vertical direction, eliminating lateral displacement or tilt, and ensuring the fit accuracy between the water retaining plate 5 and the side of the sleeper. On the other hand, its built-in damping mechanism (such as hydraulic damping, mechanical friction damping, etc.) can keep the telescopic process slow and smooth, thereby maintaining the relative position stability of the water retaining mechanism and the area to be treated on the sleeper.

[0039] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
