Technical Field
[0001] The invention belongs to the technical field of railway construction and maintenance, and in particular relates to a railway track construction and maintenance device. Background Art
[0002] Concrete pouring is a critical step in railway track construction and maintenance, including track foundation repair, trackbed reinforcement, and sleeper replacement. Traditionally, concrete pouring relies on stationary concrete mixing plants with tank trucks for transportation, or on-site concrete mixer trucks. However, in the unique environment of railway lines, conventional construction vehicles cannot travel directly on the tracks, requiring the use of railroad flatbed trucks for transportation. This complicates the process and increases time consumption.
[0003] At present, self-propelled operation and maintenance equipment (such as contact network maintenance vehicles, rail cars, etc.) are often used in railway construction or maintenance. However, when the self-propelled operation and maintenance equipment accelerates or decelerates, the concrete in the storage device shakes violently due to inertia, causing concrete stratification, affecting the pouring quality, and at the same time reducing fluidity, increasing the risk of pipeline blockage, and the storage device is unevenly stressed, shortening its service life.

[0036] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. 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 those skilled in the art without making any creative efforts shall fall within the scope of protection of the present invention.
[0037] Those skilled in the art will appreciate that although some embodiments herein include certain features included in other embodiments but not other features, the combination of features from different embodiments is intended to be within the scope of the present invention and to form different embodiments. For example, in the claims, any one of the claimed embodiments may be used in any combination.
[0038] Please refer to the attached Figure 1 To the attached Figure 10 The present invention describes a railway track construction and maintenance device.
[0039] During the construction and maintenance of railway track construction and maintenance equipment, concrete pouring is required to reinforce the contact network pillar foundation, add new guy wires or anchor foundations, construct cable trenches or grounding devices, and carry out contact network transition projects.
[0040] The railway track construction and maintenance device is a self-propelled operation and maintenance equipment 1, which includes traction power vehicles 11 at both ends, an equipment vehicle group maintenance control car 12 and a maintenance connecting car 13 in the middle.
[0041] The maintenance connection vehicle 13 of the self-propelled operation and maintenance equipment 1 is provided with a storage device 3 and a pumping system 2. The storage device 3 is used to store concrete. The pumping system 2 is connected to the storage device 3 to pump the concrete in the storage device 3 through the pumping system 2 for pouring.
[0042] Self-propelled operation and maintenance equipment can be overhead line maintenance vehicles, rail vehicles, etc.
[0043] When the self-propelled operation and maintenance equipment accelerates or decelerates, the concrete in the storage device shakes violently due to inertia, causing concrete stratification, affecting the pouring quality, and at the same time reducing fluidity, increasing the risk of pipeline blockage, and the storage device is unevenly stressed, shortening its service life.
[0044] Therefore, the storage device 3 can slide relative to the self-propelled wheel operation and maintenance equipment 1 due to inertia, and the movement of the storage device 3 can reduce the inertial impact through energy absorption.
[0045] The storage device 3 is provided with a damping assembly 5, which includes a damping slide rail, which is fixedly connected to the self-propelled wheel operation and maintenance equipment 1. A damping slider is fixedly connected to the storage device 3, and the storage device 3 is slidably connected to the damping slide rail through the damping slider;
[0046] The damping rail and the damping slider are made of low-friction coefficient materials (such as polytetrafluoroethylene-coated rails, with a friction coefficient of μ≈0.05~0.1) to ensure that the storage device 3 can slide freely when the vehicle accelerates or decelerates, and the length of the damping rail is usually designed to be ±20 cm to limit the displacement range of the storage device 3 and avoid excessive offset. Preferably, the damping rail is equipped with a V-shaped roller guide groove to ensure the uniqueness of the sliding direction and prevent lateral offset.
[0047] When the self-propelled operation and maintenance equipment 1 accelerates, the storage device 3 slides along the damping slide rail in the second direction B due to inertia, absorbing part of the kinetic energy;
[0048] When the self-propelled operation and maintenance equipment 1 decelerates, the storage device 3 slides along the damping slide rail in the first direction A due to inertia, thereby reducing the impact of concrete on the front wall of the storage device 3 .
[0049] The first direction A is the direction in which the self-propelled wheel operation and maintenance equipment 1 travels, and the second direction B is the opposite direction in which the self-propelled wheel operation and maintenance equipment 1 travels.
[0050] A buffer assembly 4 is provided on the storage device 3. When the storage device 3 slides relative to the self-propelled wheel operation and maintenance equipment 1, the buffer assembly 4 absorbs kinetic energy, and the buffer assembly 4 controls the anti-sway assembly to switch between the first state or the second state; specifically, the buffer assembly 4 includes two buffer hydraulic cylinders, and the two buffer hydraulic cylinders are respectively located at the two ends of the storage device 3. The fixed end of the buffer hydraulic cylinder is fixedly connected to the self-propelled wheel operation and maintenance equipment 1, and the output end of the buffer hydraulic cylinder is fixedly connected to the storage device 3. When the storage device 3 slides, the piston of the buffer hydraulic cylinder pushes the hydraulic oil through the throttle hole, converting the kinetic energy into heat energy dissipation.
[0051] Preferably, the hydraulic buffer is a self-resetting hydraulic buffer (spring-assisted type). When the self-propelled wheel operation and maintenance equipment 1 accelerates or decelerates, the piston of the buffer carburettor compresses the hydraulic oil and the spring stores energy at the same time; when the self-propelled wheel operation and maintenance equipment 1 travels at a constant speed, the spring force of the buffer carburettor pushes the piston to reset, and the hydraulic oil slowly returns through the reflux valve.
[0052] Regarding the reset time of the self-resetting hydraulic buffer, it is usually 1-3 seconds (depending on the viscosity of the damping oil and the spring stiffness). The reset time and timing can be determined according to actual usage needs.
[0053] An anti-sway component is provided in the storage device 3, and the anti-sway component can rotate relative to the storage device 3. The anti-sway component has a first state and a second state. When the anti-sway component is in the first state, the anti-sway component is parallel to the travel direction of the self-wheel operation and maintenance equipment 1. When the anti-sway component is in the second state, the anti-sway component is perpendicular to the travel direction of the self-wheel operation and maintenance equipment 1.
[0054] When the self-propelled operation and maintenance equipment 1 is traveling at a constant speed, the anti-sway component is in the first state, and the anti-sway component guides the concrete to flow in layers along the traveling direction. It should be noted that this may also include when the self-propelled operation and maintenance equipment 1 is stationary;
[0055] When the self-propelled operation and maintenance equipment 1 accelerates or decelerates, the storage device 3 may slide relative to the self-propelled operation and maintenance equipment 1 due to inertia, and the anti-sway component is in the second state, which blocks the movement of the concrete liquid column.
[0056] The anti-sway component includes multiple corrugated plates 7. When the anti-sway component is in the first state, the corrugated plates 7 are longitudinal corrugated plates, and the direction of the corrugated grooves of the longitudinal corrugated plates is parallel to the travel direction of the self-propelled operation and maintenance equipment 1. The longitudinal corrugated plates assist in reducing turbulence and improving pumping fluidity. When the anti-sway component is in the second state, the corrugated plates 7 are transverse corrugated plates, and the direction of the corrugated grooves of the transverse corrugated plates is perpendicular to the travel direction of the self-propelled operation and maintenance equipment 1. The transverse corrugated plates directly block the front and rear impacts of the concrete, and the anti-sway efficiency reaches 80%-90%, and the lateral concrete deviation is suppressed.
[0057] Preferably, two opposite sides of the corrugated plate 7 are provided with corrugated grooves.
[0058] When the self-propelled operation and maintenance equipment 1 accelerates or decelerates, if it is a longitudinal corrugated plate, the concrete flows freely along the corrugated groove, and the longitudinal corrugated plate has a weak anti-sway effect. When the self-propelled operation and maintenance equipment 1 is traveling at a constant speed, if it is a transverse corrugated plate, the transverse corrugated plate cannot reduce the turbulence of the concrete and improve the pumping fluidity.
[0059] Regarding the first embodiment of the arrangement of the anti-sway component, the arrangement of the storage device 3 is as follows: Figure 4 As shown, at this time, the long-line direction of the storage device 3 is located in the driving direction, and the corrugated plate 7 includes a plurality of first connecting plates 71 and a plurality of second connecting plates 72. The first connecting plates 71 are fixedly connected to the storage device 3, and the second connecting plates 72 are arranged between every two first connecting plates 71. The second connecting plates 72 can rotate relative to the first connecting plates 71. When the anti-sway component is in the first state, the second connecting plates 72 are parallel to the adjacent first connecting plates 71, and the first connecting plates 71 and the second connecting plates 72 are connected to form a longitudinal corrugated plate. When the anti-sway component is in the second state, the second connecting plates 72 are perpendicular to the first connecting plates 71, and the adjacent second connecting plates 72 are connected to form a transverse corrugated plate.
[0060] Preferably, when adjacent second connecting plates 72 are connected to form a transverse corrugated plate, the transverse corrugated plate is perpendicular to the first connecting plate 71, and the transverse corrugated plate crosses the first connecting plate 71 to form a cross corrugated plate, which suppresses shaking in all directions and is suitable for complex lines. However, the cross corrugated plate reduces the volume of the storage device 3, with a loss of about 15%-20%. Therefore, when the self-propelled operation and maintenance equipment 1 is traveling at a constant speed, the cross corrugated plate is not suitable.
[0061] Each second connecting plate 72 is fixedly connected to a rotating shaft 65, and both ends of the rotating shaft 65 respectively pass through the storage device 3 and extend outside the storage device 3. Both ends of the rotating shaft 65 extending outside the storage device 3 are fixedly connected to gears 64, and the two frames 61 are fixedly connected to the self-propelled operation and maintenance equipment 1. The two frames 61 are respectively provided with a first tooth groove 62 and a second tooth groove 63, and the gear 64 is engaged with the first tooth groove 62 or the second tooth groove 63. When the storage device 3 slides relative to the self-propelled operation and maintenance equipment 1 due to inertia, the gear 64 is engaged with the first tooth groove 62 or the second tooth groove 63 to rotate the gear 64, and the first tooth groove 62 and the second tooth groove 63 are respectively located at both ends of the gear 64, so as to ensure that when the storage device 3 slides in the first direction A or the second direction B due to inertia, the gear 64 and the second connecting plate 72 rotate in the same direction.
[0062] A sealing assembly is provided at the portion where the rotating shaft 65 passes through the storage device 3 to prevent the concrete in the storage device 3 from flowing to the outside.
[0063] When the storage device 3 slides in the first direction A due to inertia, the gear 64 engages with the first tooth groove 62, and the gear 64 separates from the second tooth groove 63, so that the gear 64 and the second connecting plate 72 rotate; when the storage device 3 slides in the second direction B due to inertia, the gear 64 engages with the second tooth groove 63, and the gear 64 separates from the first tooth groove 62, so that the gear 64 and the second connecting plate 72 rotate; the rotation directions of the gear 64 and the second connecting plate 72 are the same, so that the second connecting plate 72 can form a longitudinal corrugated plate.
[0064] Regarding the second embodiment of the arrangement of the anti-sway component, the arrangement of the storage device 3 is as follows: Figure 7As shown, at this time, the short-line direction of the storage device 3 is in the driving direction, and a connecting ring 73 is fixedly connected in the storage device 3, and an arc-shaped piston cylinder 74 is fixedly connected in the connecting ring 73. A sealing plug is provided in the arc-shaped piston cylinder 74, and the sealing plug can slide relative to the arc-shaped piston cylinder 74. An arc-shaped piston rod 75 is connected to the sealing plug, and a slider 76 is fixedly connected to the arc-shaped piston rod 75. The slider 76 can slide along the connecting ring 73. The slider 76 is connected to the anti-sway component to control the anti-sway component to switch between the first state and the second state through the sliding of the slider 76. The buffer hydraulic pressure is connected to a first pipeline, and the two first pipelines are respectively connected to the two inlets of the switching valve. The outlet of the switching valve is connected to a second pipeline, and the second pipeline is connected to the arc-shaped piston cylinder 74.
[0065] Specifically, the arcuate profile of the connecting ring 73 matches the arcuate profile of the storage device 3 , the arcuate piston cylinder 74 matches the arcuate profile of the arcuate piston rod 75 , and the arcuate piston cylinder 74 matches the arcuate profile of the connecting ring 73 .
[0066] When the storage device 3 slides in the first direction A due to inertia, the first pipeline at the second direction B end is connected to the second pipeline, and the piston of the hydraulic buffer at the second direction B end is stretched, so that the hydraulic buffer at the second direction B end generates negative pressure, causing the sealing plug of the arc-shaped piston cylinder 74 and the arc-shaped piston rod 75 to slide into the arc-shaped piston cylinder 74, causing the slider 76 to slide toward the arc-shaped piston cylinder 74 until the anti-sway assembly is in the second state, and the direction of the corrugated groove of the corrugated plate 7 is perpendicular to the travel direction of the self-wheel operation and maintenance equipment 1.
[0067] When the storage device 3 slides toward the second direction B due to inertia, the first pipeline at the first direction A end is connected to the second pipeline, and the piston of the hydraulic buffer at the first direction A end is stretched, so that the hydraulic buffer at the first direction A end generates negative pressure, causing the sealing plug of the arc-shaped piston cylinder 74 and the arc-shaped piston rod 75 to slide into the arc-shaped piston cylinder 74, causing the slider 76 to slide toward the arc-shaped piston cylinder 74 until the anti-sway assembly is in the second state, and the direction of the corrugated groove of the corrugated plate 7 is perpendicular to the travel direction of the self-wheel operation and maintenance equipment 1.
[0068] The anti-sway component can be retracted or expanded relative to the storage device 3. When the anti-sway component switches from the first state to the second state, the anti-sway component changes from contraction to expansion. When the anti-sway component switches from the second state to the first state, the anti-sway component changes from expansion to contraction. Specifically, a connecting assembly 8 is connected to the connecting ring 73, and multiple corrugated plates 7 are connected by the connecting assembly 8. The connecting assembly 8 includes a first rod body 82 and a second rod body 81. The middle parts of each two crossed first rod bodies 82 are hinged by a pin, and the pin in the middle of the first rod body 82 is connected to the corrugated plate 7. The ends of each two adjacent first rod bodies 82 are hinged by a pin, and the first rod bodies 82 at both ends are hinged to the second rod body 81 by a pin, and the adjacent second rod bodies 81 are hinged by a pin. The pin of the second rod body 81 at the end C in the third direction is connected to the connecting ring 73, and the pin of the second rod body 81 at the end D in the fourth direction is connected to the corrugated plate 7. A hydraulic cylinder 83 is connected to the connecting ring 73, and the output end of the hydraulic cylinder 83 is fixedly connected to the corrugated plate 7 at the end C in the third direction. When the state is switched to the second state, the output end of the hydraulic cylinder 83 moves toward the fourth direction D end, and the corrugated plate 7 is transformed from contraction to expansion through the connecting component 8, that is, in the second state, the distance between the corrugated plates 7 is relatively far, so when it is a transverse corrugated plate, it is in an expanded state, blocking the front and rear impact of concrete in a large range, and increasing the blocking range. When the anti-sway component is switched from the second state to the first state, the output end of the hydraulic cylinder 83 moves toward the third direction C end, and the corrugated plate 7 is transformed from expansion to contraction through the connecting component 8, that is, in the first state, the distance between the corrugated plates 7 is relatively close, so when it is a longitudinal corrugated plate, it is in a contracted state, increasing the volume of the storage device 3, and ensuring that the longitudinal corrugated plate assists in reducing turbulence and improving pumping fluidity. At the same time, when the first state is switched to the second state, the switching resistance of the anti-sway component is reduced.
[0069] Specifically, each corrugated plate 7 is provided with an open groove, and the pin shaft in the middle of the first rod body 82 is connected to the open groove of the corrugated plate 7. Through the open groove of the corrugated plate 7, when the first rod body 82 rotates relative to the pin shaft in the middle, there is no interference. The pin shaft of the second rod body 81 at the fourth direction D end is connected to the open groove of the corrugated plate 7 at the fourth direction D end, and at the same time, it is avoided that the pin shaft of the second rod body 81 at the fourth direction D end rotates without interfering with the corrugated plate 7.
[0070] An open groove is provided on the connecting ring 73 , and the pin shaft of the second rod body 81 at the third direction C end is connected to the open groove of the connecting ring 73 . The open groove of the connecting ring 73 prevents interference when the second rod body 81 at the third direction C end rotates.
