Description

Technical Field

[0001] The present invention belongs to the technical field of railway construction and maintenance, and particularly relates to a railway track construction and maintenance device. Background Art

[0002] In the construction and maintenance of railway tracks, concrete pouring is a key link in operations such as track foundation repair, ballast bed reinforcement, and sleeper replacement. Traditional concrete pouring usually relies on a fixed mixing plant in cooperation with a tanker truck for transportation, or uses a trailer-mounted mixer truck for on-site operations. However, in the special environment of railway lines, ordinary engineering vehicles cannot directly drive on the rails and need to rely on a track flatbed truck for transportation, resulting in complex processes and increased time consumption.

[0003] Currently, in railway construction and maintenance, self-propelled maintenance equipment (such as catenary maintenance vehicles, rail cars, etc.) is often used for construction or maintenance. However, when the self-propelled maintenance equipment accelerates or decelerates, the concrete in the storage device shakes violently due to inertia, resulting in concrete stratification, affecting the pouring quality, and at the same time, the fluidity decreases, increasing the risk of pipeline blockage, and the storage device is unevenly stressed, shortening its service life.

[0004] Therefore, there is an urgent need to design a railway track construction and maintenance device to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a railway track construction and maintenance device, which has the advantage of changing the state of the anti-shake component according to the driving state of the self-propelled maintenance equipment, thereby suppressing shaking, and solves the problems mentioned in the background art.

[0006] To achieve the above purpose, the specific technical solution of a railway track construction and maintenance device of the present invention is as follows: A railway track construction and maintenance device includes traction power vehicles at both ends, an equipment vehicle group maintenance control carriage and a maintenance connection carriage located between the traction power vehicles. A storage device and a pumping system are provided on the maintenance connection carriage. The pumping system is connected to the storage device. The storage device can slide relative to the maintenance connection carriage under inertia. An anti-shake component is provided inside the storage device, and the anti-shake component can rotate relative to the storage device; The anti-shake component has a first state and a second state; When the self-propelled maintenance equipment is traveling at a constant speed, the anti-shake component is in the first state, and the anti-shake component is parallel to the traveling direction of the self-propelled maintenance equipment; When the self-propelled maintenance equipment accelerates or decelerates, the anti-shake component is in the second state, and the anti-shake component is perpendicular to the traveling direction of the self-propelled maintenance equipment.

[0007] Further, the anti-sway component includes a plurality of corrugated plates. When the anti-sway component is in the first state, the corrugated plates are longitudinal corrugated plates, and the direction of the corrugation grooves of the longitudinal corrugated plates is parallel to the traveling direction of the self-propelled maintenance equipment. When the anti-sway component is in the second state, the corrugated plates are transverse corrugated plates, and the direction of the corrugation grooves of the transverse corrugated plates is perpendicular to the traveling direction of the self-propelled maintenance equipment.

[0008] Further, the corrugated plates include a plurality of first connecting plates and a plurality of second connecting plates. The first connecting plates are fixedly connected to the storage device. The second connecting plates are arranged between every two first connecting plates, and the second connecting plates can rotate relative to the first connecting plates. When the anti-sway component is in the first state, the second connecting plates are parallel to the adjacent first connecting plates, and the first connecting plates and the second connecting plates are connected to form longitudinal corrugated plates. When the anti-sway component is in the second state, the second connecting plates are perpendicular to the first connecting plates, and the adjacent second connecting plates are connected to form transverse corrugated plates.

[0009] Further, a rotating shaft is fixedly connected to each second connecting plate. Both ends of the rotating shaft penetrate through the storage device and extend outside the storage device. Gears are fixedly connected to the two ends of the rotating shaft extending outside the storage device. Two frames are fixedly connected to the self-propelled maintenance equipment. A first tooth groove and a second tooth groove are respectively formed on the two frames. The gears are engaged with the first tooth groove or the second tooth groove. When the storage device slides relative to the self-propelled maintenance equipment due to inertia, the gears are engaged with the first tooth groove or the second tooth groove to make the gears rotate, and the first tooth groove and the second tooth groove are respectively located at both ends of the gears.

[0010] Further, a connecting ring is fixedly connected inside the storage device. An arc-shaped piston cylinder is fixedly connected inside the connecting ring. A sealing plug is arranged inside the arc-shaped piston cylinder, and the sealing plug can slide relative to the arc-shaped piston cylinder. An arc-shaped piston rod is connected to the sealing plug. A slider is fixedly connected to the arc-shaped piston rod, and the slider can slide along the connecting ring. The slider is connected to the anti-sway component to control the switching of the anti-sway component between the first state and the second state through the sliding of the slider.

[0011] Further, the anti-sway component can contract or expand relative to the storage device. 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.

[0012] Further, a connection component is connected to the connection ring, and multiple corrugated plates are connected through the connection component.

The pin shaft of the second rod body at the third-direction end is connected to the connection ring, and the pin shaft of the second rod body at the fourth-direction end is connected to the corrugated plate. A hydraulic cylinder is connected to the connection ring, and the output end of the hydraulic cylinder is fixedly connected to the corrugated plate at the third direction end. When the anti-sway component switches from the first state to the second state, the output end of the hydraulic cylinder moves towards the fourth direction end. When the anti-sway component switches from the second state to the first state, the output end of the hydraulic cylinder moves towards the third direction end.

[0013] Further, a damping component is provided on the storage device. The damping component includes a damping slide rail, which is fixedly connected to the self-propelled maintenance equipment. A damping slider is fixedly connected to the storage device. The storage device is slidably connected to the damping slide rail through the damping slider; When the self-propelled maintenance equipment is traveling at a constant speed, the anti-sway component is in the first state; When the self-propelled maintenance equipment is accelerating or decelerating, the storage device slides relative to the self-propelled maintenance equipment through the damping component, and the anti-sway component is in the second state; When the self-propelled maintenance equipment is accelerating, the storage device slides towards the second direction; When the self-propelled maintenance equipment is decelerating, the storage device slides towards the first direction.

[0014] Further, a buffer component is provided on the storage device. When the storage device slides relative to the self-propelled maintenance equipment, the buffer component absorbs kinetic energy and controls the anti-sway component to switch between the first state and the second state through the buffer component.

[0015] Further, the buffer component includes two buffer hydraulic cylinders, which are respectively located at both ends of the storage device. The fixed ends of the buffer hydraulic cylinders are fixedly connected to the self-propelled maintenance equipment, and the output ends of the buffer hydraulic cylinders are fixedly connected to the storage device.

[0016] The present invention has the following advantages: This railway construction and maintenance device changes the state of the anti-sway component according to the driving state of the vehicle. When the self-propelled maintenance equipment is traveling at a constant speed, the anti-sway component is in the first state. The anti-sway component guides the concrete to flow in layers along the driving direction and helps reduce turbulence, improving the pumping fluidity. When the self-propelled maintenance equipment is accelerating or decelerating, the anti-sway component is in the second state. The anti-sway component directly blocks the front and back impacts of the concrete and inhibits the lateral offset of the concrete. Brief Description of the Drawings

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Those skilled in the art can understand that although some embodiments herein include certain features included in other embodiments rather than other features, the combination of features of different embodiments means that it is within the scope of the present invention and forms different embodiments. For example, in the claims, any one of the claimed embodiments can be used in any combination.

[0020] The following refers to the attached Figure 1 to the attached Figure 10 Describe a railway track construction and maintenance device of the present invention.

[0021] During the construction and maintenance of the railway track by the railway track construction and maintenance device, for the reinforcement of the catenary pole foundation, the addition of guy wire or anchor foundation, the construction of cable trenches or grounding devices, the catenary transition project, etc., concrete pouring is required.

[0022] The railway track construction and maintenance device is a self-propelled operation and maintenance equipment 1. The self-propelled operation and maintenance equipment 1 includes traction power vehicles 11 at both ends, and an equipment vehicle group maintenance control carriage 12 and a maintenance connection vehicle 13 in the middle.

[0023] A storage device 3 and a pumping system 2 are provided on the maintenance connection vehicle 13 of the self-propelled operation and maintenance equipment 1. The storage device 3 is used to store concrete, and the pumping system 2 is connected to the storage device 3 to pump and pour the concrete in the storage device 3 through the pumping system 2.

[0024] The self-propelled operation and maintenance equipment can be a catenary maintenance vehicle, a rail vehicle, etc.

[0025] When the self-propelled operation and maintenance equipment accelerates or decelerates, the concrete in the storage device shakes violently due to inertia, resulting in the stratification of the concrete, affecting the pouring quality. At the same time, the fluidity decreases, increasing the risk of pipeline blockage, and the storage device is unevenly stressed, shortening the service life.

[0026] Therefore, the storage device 3 can slide relative to the self-propelled operation and maintenance equipment 1 under inertia, and the inertial impact can be reduced by the movement of the storage device 3 through energy absorption.

[0027] A damping component 5 is provided on the storage device 3. The damping component 5 includes a damping slide rail, the damping slide rail is fixedly connected to the self-propelled 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; The damping slide rail and the damping slider are made of materials with a low friction coefficient (such as a polytetrafluoroethylene-coated guide rail, with a friction coefficient μ≈0.05 - 0.1), ensuring that the storage device 3 can slide freely when the vehicle accelerates or decelerates. And the length of the damping slide rail is usually designed to be ±20 cm to limit the displacement range of the storage device 3 and avoid excessive deviation. Preferably, the damping slide rail is equipped with a V-shaped roller guide groove to ensure the uniqueness of the sliding direction and prevent lateral deviation.

[0028] When the self-propelled 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; When the self-propelled maintenance equipment 1 decelerates, the storage device 3 slides along the damping slide rail in the first direction A due to inertia, reducing the impact of concrete on the front wall of the storage device 3.

[0029] The first direction A is the traveling direction of the self-propelled maintenance equipment 1, and the second direction B is the opposite direction of the traveling of the self-propelled maintenance equipment 1.

[0030] A buffer assembly 4 is provided on the storage device 3. When the storage device 3 slides relative to the self-propelled maintenance equipment 1, the buffer assembly 4 absorbs kinetic energy and controls the anti-sway assembly to switch between the first state and the second state through the buffer assembly 4; specifically, the buffer assembly 4 includes two buffer hydraulic cylinders, and the two buffer hydraulic cylinders are respectively located at both ends of the storage device 3. The fixed end of the buffer hydraulic cylinder is fixedly connected to the self-propelled 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 and dissipating it.

[0031] Preferably, the hydraulic buffer is a self-resetting hydraulic buffer (spring-assisted type). When the self-propelled maintenance equipment 1 accelerates or decelerates, the piston of the buffer hydraulic cylinder compresses the hydraulic oil, and the spring stores energy at the same time; when the self-propelled maintenance equipment 1 travels at a constant speed, the spring force of the buffer hydraulic cylinder pushes the piston to reset, and the hydraulic oil slowly returns through the return valve.

[0032] 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 stiffness of the spring), and the reset time and timing can be determined according to actual usage needs.

[0033] An anti-sway assembly is provided inside the storage device 3. The anti-sway assembly can rotate relative to the storage device 3. The anti-sway assembly has a first state and a second state. When the anti-sway assembly is in the first state, the anti-sway assembly is parallel to the traveling direction of the self-propelled maintenance equipment 1. When the anti-sway assembly is in the second state, the anti-sway assembly is perpendicular to the traveling direction of the self-propelled maintenance equipment 1; When the self-propelled maintenance equipment 1 travels at a constant speed, the anti-sway assembly is in the first state, and the anti-sway assembly guides the concrete to flow in layers along the traveling direction. It should be noted that it can also include when the self-propelled maintenance equipment 1 is stationary; When the self-propelled maintenance equipment 1 accelerates or decelerates, the storage device 3 can slide relative to the self-propelled maintenance equipment 1 due to inertia, and the anti-sway assembly is in the second state, and the anti-sway assembly blocks the movement of the concrete liquid column.

[0034] 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 corrugation grooves of the longitudinal corrugated plates are parallel to the driving direction of the self-propelled maintenance equipment 1. By means of the longitudinal corrugated plates, the turbulence is reduced and the pumping fluidity is improved. When the anti-sway component is in the second state, the corrugated plates 7 are transverse corrugated plates, and the corrugation grooves of the transverse corrugated plates are perpendicular to the driving direction of the self-propelled maintenance equipment 1. By means of the transverse corrugated plates, the front and back impacts of the concrete are directly blocked, the anti-sway efficiency reaches 80%-90%, and the lateral offset of the concrete is inhibited.

[0035] Preferably, corrugation grooves are provided on both opposite sides of the corrugated plate 7.

[0036] When the self-propelled maintenance equipment 1 is accelerating or decelerating, if it is a longitudinal corrugated plate at this time, the concrete flows freely along the corrugation grooves, and the anti-sway effect of the longitudinal corrugated plate is weak. When the self-propelled maintenance equipment 1 is traveling at a constant speed, if it is a transverse corrugated plate at this time, the transverse corrugated plate cannot reduce the turbulence of the concrete and improve the pumping fluidity.

[0037] Regarding the first embodiment of the setting method of the anti-sway component, the setting method of the storage device 3 is as Figure 4 shown. At this time, the long side direction of the storage device 3 is in the driving direction. The corrugated plate 7 includes multiple first connecting plates 71 and multiple second connecting plates 72. The first connecting plates 71 are fixedly connected to the storage device 3. 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 longitudinal corrugated plates. 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 transverse corrugated plates.

[0038] Preferably, when the adjacent second connecting plates 72 are connected to form a transverse corrugated plate, at this time, the transverse corrugated plate is perpendicular to the first connecting plate 71, and the transverse corrugated plate and the first connecting plate 71 cross to form a cross corrugated plate, which has all-direction anti-sway and is suitable for complex lines. However, the cross corrugated plate reduces the volume of the storage device 3 by about 15%-20%. Therefore, when the self-propelled maintenance equipment 1 is traveling at a constant speed, the cross corrugated plate is not applicable.

[0039] Each second connecting plate 72 is fixedly connected with a rotating shaft 65. Both ends of the rotating shaft 65 penetrate through the storage device 3 and extend outside the storage device 3. The two ends of the rotating shaft 65 extending outside the storage device 3 are fixedly connected with gears 64. The two frames 61 are fixedly connected with the self-propelled maintenance equipment 1. The first tooth groove 62 and the second tooth groove 63 are respectively formed on the two frames 61. The gear 64 meshes with the first tooth groove 62 or the second tooth groove 63. When the storage device 3 slides relative to the self-propelled maintenance equipment 1 due to inertia, the gear 64 meshes with the first tooth groove 62 or the second tooth groove 63, so that the gear 64 rotates. 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 rotation directions of the gear 64 and the second connecting plate 72 are the same.

[0040] A sealing assembly is provided at the part where the rotating shaft 65 penetrates through the storage device 3, so that the concrete in the storage device 3 will not flow to the outside.

[0041] When the storage device 3 slides in the first direction A due to inertia, the gear 64 meshes with the first tooth groove 62, and the gear 64 is separated 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 meshes with the second tooth groove 63, and the gear 64 is separated 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 plates 72 can form longitudinal corrugated plates.

[0042] Regarding the second embodiment of the setting method of the anti-sway component, the setting method of the storage device 3 is as Figure 7 shown. At this time, the short side direction of the storage device 3 is in the driving direction. A connecting ring 73 is fixedly connected inside the storage device 3. An arc-shaped piston cylinder 74 is fixedly connected inside the connecting ring 73. A sealing plug is provided inside the arc-shaped piston cylinder 74. 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. 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, so as 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 cylinders are both connected with a first pipeline. The two first pipelines are respectively connected to the two inlets of the switching valve. The outlet of the switching valve is connected with a second pipeline. The second pipeline is connected to the arc-shaped piston cylinder 74.

[0043] Specifically, the arc-shaped contour of the connecting ring 73 matches the arc-shaped contour of the storage device 3, the arc-shaped contour of the arc-shaped piston cylinder 74 matches the arc-shaped contour of the arc-shaped piston rod 75, and the arc-shaped contour of the arc-shaped piston cylinder 74 matches the arc-shaped contour of the connecting ring 73.

[0044] When the storage device 3 slides in the first direction A due to inertia, the first pipeline at the second direction B end is communicated with the second pipeline, and the piston of the hydraulic buffer at the second direction B end is stretched, so that a negative pressure is generated in the hydraulic buffer at the second direction B end, causing the sealing plug of the arc piston cylinder 74 and the arc piston rod 75 to slide into the arc piston cylinder 74, making the slider 76 slide towards the arc piston cylinder 74 until the anti-sway component is in the second state, and the corrugation groove direction of the corrugated plate 7 is perpendicular to the driving direction of the self-propelled maintenance equipment 1.

[0045] When the storage device 3 slides in the second direction B due to inertia, the first pipeline at the first direction A end is communicated with the second pipeline, and the piston of the hydraulic buffer at the first direction A end is stretched, so that a negative pressure is generated in the hydraulic buffer at the first direction A end, causing the sealing plug of the arc piston cylinder 74 and the arc piston rod 75 to slide into the arc piston cylinder 74, making the slider 76 slide towards the arc piston cylinder 74 until the anti-sway component is in the second state, and the corrugation groove direction of the corrugated plate 7 is perpendicular to the driving direction of the self-propelled maintenance equipment 1.

[0046] The anti-sway component can contract or expand 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 connection component 8 is connected to the connection ring 73, and a plurality of corrugated plates 7 are connected through the connection component 8. The connection component 8 includes a first rod body 82 and a second rod body 81. The middle parts of every two intersecting first rod bodies 82 are hinged through a pin shaft. The pin shaft in the middle of the first rod body 82 is connected to the corrugated plate 7. The ends of every two adjacent first rod bodies 82 are hinged through a pin shaft. The first rod bodies 82 at both ends are hinged to the second rod body 81 through a pin shaft. The adjacent second rod bodies 81 are hinged through a pin shaft. The pin shaft of the second rod body 81 at the third direction C end is connected to the connection ring 73, and the pin shaft of the second rod body 81 at the fourth direction D end is connected to the corrugated plate 7. A hydraulic cylinder 83 is connected to the connection ring 73, and the output end of the hydraulic cylinder 83 is fixedly connected to the corrugated plate 7 at the third direction C end. When the anti-sway component switches from the first state to the second state, the output end of the hydraulic cylinder 83 moves towards the fourth direction D end, and the corrugated plate 7 changes from contraction to expansion through the connection component 8, that is, when in the second state, the distance between the corrugated plates 7 is farther, so when the corrugated plates are in the horizontal direction, it is in the expanded state, blocking the front and back impacts of the concrete over a large range and increasing the blocking range. When the anti-sway component switches from the second state to the first state, the output end of the hydraulic cylinder 83 moves towards the third direction C end, and the corrugated plate 7 changes from expansion to contraction through the connection component 8, that is, when in the first state, the distance between the corrugated plates 7 is closer, so when the corrugated plates are in the longitudinal direction, it is in the contracted state, increasing the volume of the storage device 3, and ensuring that the longitudinal corrugated plates assist in reducing turbulence and improving pumping fluidity. At the same time, when switching from the first state to the second state, the switching resistance of the anti-sway component is reduced.

[0047] Specifically, each corrugated plate 7 is provided with an opening groove. The pin shaft in the middle of the first rod body 82 is connected to the opening groove of the corrugated plate 7. Through the opening groove of the corrugated plate 7, when the first rod body 82 rotates relative to the pin shaft in the middle, there will be no interference. The pin shaft of the second rod body 81 at the D end in the fourth direction is connected to the opening groove of the corrugated plate 7 at the D end in the fourth direction, and at the same time, when the pin shaft of the second rod body 81 at the D end in the fourth direction rotates, it will not interfere with the corrugated plate 7.

[0048] The connecting ring 73 is provided with an opening groove. The pin shaft of the second rod body 81 at the C end in the third direction is connected to the opening groove of the connecting ring 73. Through the opening groove of the connecting ring 73, when the second rod body 81 at the C end in the third direction rotates, there will be no interference.

[0049] Obviously, the above-mentioned embodiments of the present invention are only examples for clearly explaining the present invention, and are not intended to limit the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here.
