Description

Technical Field

[0001] This application relates to the field of railway line maintenance technology, specifically to a turnout rail welding vehicle. Background Technology

[0002] Currently, the welding of rail joints at stations and turnouts is mainly carried out manually with small machines due to the complex working conditions of the turnout pre-laying site and the complicated process of getting the equipment to the welding position. This method requires a large number of workers to weld rails at the turnout, resulting in high labor intensity and high labor costs. At the same time, due to different work experience, the welding quality of the welds is inconsistent, and the comprehensive mechanical properties of the welds are different in different places. They cannot pass the rigorous drop hammer test in the rail type test, resulting in a reduction in weld strength and rail service life.

[0003] Due to the limitations of manual welding, it is impossible to simultaneously meet and solve the high requirements for welding quality, such as high strength, high smoothness, and high-precision fixed length dimensions, in turnout rail welding.

[0057] This invention discloses a turnout rail welding vehicle to solve the problem that welding quality cannot be guaranteed due to the complex road conditions at turnouts, which necessitates manual support of welding equipment.

[0058] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0059] Please see Figure 1-4 , Figure 1 This is a front view structural schematic diagram of a turnout rail welding operation vehicle provided in an embodiment of this application; Figure 2 for Figure 1 A schematic diagram of the side view structure; Figure 3 for Figure 1 A top-view structural diagram; Figure 4 A schematic diagram of the structure of the turnout rail welding vehicle provided in this application, which uses a crawler traveling device 4 for travel; Figure 5 A schematic diagram of the isometric structure of the transfer trolley 6 provided in this application; Figure 6 A schematic diagram of the installation structure of the auxiliary support device 67 provided in this application; Figure 7 This is a schematic diagram of the structure of the transfer trolley 6 in operation according to the first embodiment of this application; Figure 8 This is a schematic diagram of the structure of the transfer trolley 6 in operation according to the second embodiment of this application; Figure 9 This is a schematic diagram of the working structure of the transfer trolley 6 with temporary track 200 provided in the third embodiment of this application.

[0060] In one specific embodiment, the turnout rail welding vehicle provided in this application includes welding equipment 2, a traveling platform 1, a traveling wheel device 3, a crawler traveling device 4, and a switching device 5. The welding equipment 2 is a CNC welding device, preferably an equipment corresponding to flash welding, which will not be described in detail here. The traveling platform 1 serves as the carrying device of the turnout rail welding vehicle. Traveling components are respectively installed below the traveling platform 1, specifically using the traveling wheel device 3 and the crawler traveling device 4. The traveling wheel device 3 drives the traveling platform 1 to travel on the track 100. When the travel conditions of the traveling wheel device 3 are not met on the track, the crawler traveling device 4 can drive the traveling platform 1 to travel on the ground, thereby achieving on-line or off-line travel. Its operation is flexible and meets different working conditions.

[0061] Among them, the direction of the railway line extension is called the longitudinal direction, the horizontal direction perpendicular to the railway line extension direction is called the transverse direction, and the direction perpendicular to the horizontal plane is called the vertical direction.

[0062] Specifically, a switching device 5 is used to switch between the running wheel device 3 and the track traveling device 4. One end of the switching device 5 is connected to the running platform 1, and the other end is connected to the running wheel device 3 or the track traveling device 4. It is used to adjust the vertical height between the running wheel device 3 and the track traveling device 4 so as to switch the running of the running wheel device 3 and the track traveling device 4.

[0063] When switching the traveling mechanism using the switching device 5, in some embodiments, one end of the switching device 5 is connected to the traveling platform 1, and the other end is connected to the traveling wheel device 3. The switching device 5 drives the traveling wheel device 3 to move vertically relative to the track traveling device 4. When the traveling surface of the traveling wheel device 3 is lower than the traveling surface of the track traveling device 4 in the vertical direction, the traveling wheel device 3, as a support and traveling mechanism, contacts the ground or track 100, and the traveling platform 1 travels by driving the traveling wheel device 3. When the switching device 5 drives the traveling wheel device 3 to move vertically upward relative to the track traveling device 4, until the traveling surface of the traveling wheel device 3 is higher than the traveling surface of the track traveling device 4, the track traveling device 4, as a support and traveling mechanism, contacts the ground, and the traveling platform 1 travels by driving the track traveling device 4. It is understood that the traveling wheel device 3 and the track traveling device 4 are preferably each provided with a driving device to achieve self-propelled movement.

[0064] Compared with the prior art, the turnout rail welding vehicle provided in this application has the following technical advantages:

[0065] Welding equipment 2 is installed on the traveling platform 1. A traveling wheel device 3 and a tracked traveling device 4 are respectively installed below the traveling platform 1. The traveling wheel device 3 can travel on the track 100, while the tracked traveling device 4 is used for ground-level movement. A switching device 5 allows for switching between the traveling wheel device 3 and the tracked traveling device 4. This flexible movement mode meets the needs of different working conditions. When traveling on the track 100, the traveling wheel device 3 can be used, offering high speed and shortening transportation time. When the rail welding vehicle travels to complex sections such as turnouts, the tracked traveling device 4 can be used for either online or offline movement to adapt to different working conditions. This eliminates the need for manual support of the welding equipment and enables CNC rail welding, improving welding quality, unifying the comprehensive mechanical properties of the weld, increasing weld strength and rail service life, and providing a material basis for high-speed rail acceleration.

[0066] In this embodiment, the traveling platform 1 is longitudinally provided with at least two sets of traveling wheel devices 3. Each set of traveling wheel devices 3 includes a traveling shaft and two traveling wheels rotatably connected to the traveling shaft. The traveling shaft is arranged laterally, and the traveling wheels are rotatably connected to the traveling shaft. A switching device 5 is provided between each set of traveling wheel devices 3 and the traveling platform 1. One end of the switching device 5 is connected to the traveling platform 1, and the other end is fixedly connected to the traveling shaft to drive the traveling wheel devices 3 to move vertically telescopically. The switching device 5 is preferably configured as a cylinder, hydraulic cylinder, or other driving device, which will not be described in detail here.

[0067] To adapt to the structural characteristics of the turnout, in the transverse direction of the running platform 1, the tracked traveling device 4 is located outside the traveling wheel device 3, thereby reducing the interference of the tracked traveling device 4 on the traveling wheel device 3 during travel. In the longitudinal direction of the running platform 1, at least one set of traveling wheel devices 3 is provided at both ends of the longitudinal extension line of the tracked traveling device 4, so as to form a quadrilateral structure with the transversely arranged tracked traveling device 4, thereby improving the stability of the working vehicle. In the case of poor road conditions, the traveling wheel device 3 and the tracked traveling device 4 can also be used for travel at the same time. In this process, the tracked traveling device 4 is given priority as the main power source, and the traveling wheel device 3 follows along.

[0068] In some embodiments, the welding equipment 2 includes a welding device 21, a boom 22, and a cooling device 23. The welding device 21 can be positioned on the traveling platform 1 to perform turnout welding. The welding device 21 is preferably configured as a flash welding device, and its specific structure can be set according to the development level of the prior art. The boom 22 is rotatably connected to the front end of the traveling platform 1 and can be extended and retracted along the length direction (longitudinal direction) of the traveling platform 1. The boom 22 has a hook that can move vertically. The boom 22 enables the welding device 21 to rotate in the horizontal plane, extend and retract longitudinally, and extend and retract vertically. During welding, the boom 22 is connected to the welding device 21 and works together with the traveling platform 1 to adjust the longitudinal, lateral, and vertical positions of the welding device 21 to weld the turnout. The cooling device 23 provides water cooling for the welding device 21, and the specific structure of the cooling device 23 can be set with reference to the prior art.

[0069] Furthermore, the rail welding vehicle also includes a power system 9, which is fixed above the traveling platform 1. The power system 9 includes a charger 91, a battery cabinet 92, an electrical control cabinet 93, and an autotransformer 94. The charger 91 is connected to an external power source and charges the battery cabinet 92. The voltage of the battery cabinet 92 is converted into a voltage usable by the welding equipment 2 and the hydraulic system 7 through the electrical control cabinet 93 and the autotransformer 94. When it is inconvenient to connect an external power source for charging but there is a construction need, a generator can be added to charge the battery cabinet 92.

[0070] The hydraulic system 7 and electrical system 8 are also fixed on the traveling platform 1. The hydraulic system 7 is connected to the traveling wheel device 3, the crawler traveling device 4, the welding equipment 2, and the transfer trolley 6 to provide hydraulic power. The hydraulic system 7 is equipped with an emergency pump, which can perform emergency operations or emergency vehicle retrieval in case of pump station failure. The electrical system 8 is connected to the welding equipment 2, the power system 9, and the hydraulic system 7 for electrical control.

[0071] In some embodiments, to adapt to different working conditions, the aforementioned turnout rail welding vehicle further includes a transfer trolley 6. The transfer trolley 6 includes a body 61, a trolley traveling device 62, and a hoisting and moving device. The body 61 has a accommodating space for carrying the welding equipment 2 or transporting materials. Preferably, the body 61 is configured as a frame structure to facilitate the placement and retrieval of the welding equipment 2 and prevent the welding equipment 2 from rubbing against each other during hoisting. The body 61 can span across both sides of the track to facilitate the online movement of the welding equipment 2 to the two sides of the turnout track 100 for operation. The trolley traveling device 62 is located below the body 61, and its drive side travels on the track 100 or the turnout ground. The trolley traveling device 62 can be configured as a traveling wheel, rubber wheel, or track mechanism, which can be configured as needed, all of which are within the scope of protection of this application. The trolley traveling device 62 preferably has a driving component to achieve self-propelled movement.

[0072] The hoisting and moving device is located on the vehicle body 61, which drives the welding equipment 2 to move laterally, longitudinally and vertically along the vehicle body 61, and moves the welding equipment 2 to the preset welding position to perform welding operations. The hoisting and moving position can be set as a robotic arm or other moving mechanism.

[0073] The aforementioned transfer trolley 6 allows the trolley body 61 to span both sides of the track and provides storage space for placing welding equipment 2 or other transport materials, while also providing space for the welding equipment to move. The trolley's traveling device 62 is fixed to both ends of the trolley body 61 laterally, facilitating movement on the track 100 and / or the ground. The lifting and moving device can lift and move the welding equipment 2 along at least one direction (lateral, longitudinal, and vertical) of the trolley body 61, moving it to a preset welding position for welding operations. The transfer trolley 6 enables multi-directional movement of the welding equipment 2 or transport materials, facilitating the positioning of the welding equipment 2 and reducing labor intensity. Furthermore, the transfer trolley 6 can work in conjunction with a turnout rail welding vehicle, improving adaptability and overall operational flexibility.

[0074] Specifically, the lifting and moving device includes a vertical lifting assembly 63, a horizontal moving assembly 64, and a longitudinal moving assembly 65. The vertical lifting assembly 63 is used to lift the welding equipment 2 and can move the welding equipment 2 vertically. Specifically, the vertical lifting assembly 63 can be configured as a boom 22, which lifts the welding equipment 2 via a hook, which can move the welding equipment 2 vertically. The horizontal moving assembly 64 is slidably connected to the top of the vehicle body 61, and the vertical lifting assembly 63 is located on the horizontal moving assembly 64, such as a detachable fixed connection. The horizontal moving assembly 64 drives the vertical lifting assembly 63 and the welding equipment 2 to move laterally along the vehicle body 61, thereby adjusting the welding position of the welding equipment 2 laterally.

[0075] The lateral movement assembly 64 includes a lateral movement mounting base 641 and a lateral power drive component 642. The lateral movement mounting base 641 has first lateral sliding members 643 at both longitudinal ends. The first lateral sliding members 643 can be configured as pulleys, sliders, or other sliding structures. A first lateral sliding groove 614 is provided on the top of the vehicle body 61, extending laterally along the vehicle body 61. The first lateral sliding members 643 slide on the first lateral sliding groove 614. One end of the lateral power drive component 642 is connected to the vehicle body 61, and the other end is connected to the lateral movement mounting base 641, driving the first lateral sliding members 643 of the lateral movement mounting base 641 to slide within the first lateral sliding groove 614, thereby adjusting the welding equipment 2 in the lateral position. The lateral power drive component 642 includes a motor, a gear, and a rack. The rack is arranged laterally along the vehicle body 61. The motor drives the gear to move on the rack, achieving power drive. The gear and rack mechanism has high transmission accuracy, reducing movement errors and improving welding accuracy.

[0076] In some embodiments, the longitudinal moving assembly 65 includes a longitudinal moving mounting base and a longitudinal power drive. A vertical lifting assembly 63 is mounted on the longitudinal moving mounting base. The bottom of the longitudinal moving mounting base has a longitudinal sliding member extending along its length (longitudinal direction). The longitudinal moving mounting base is located on a transverse moving mounting base 641. The top of the transverse moving mounting base 641 has a longitudinally extending groove. The longitudinal sliding member cooperates with the longitudinal groove to drive the welding equipment 2 to move longitudinally. To improve automation, one end of the longitudinal power drive is connected to the transverse moving assembly 64, and the other end is connected to the longitudinal moving mounting base, for driving the longitudinal moving mounting base and the vertical lifting assembly 63 to move longitudinally relative to the transverse moving assembly 64. The longitudinal power drive can be configured as a cylinder or hydraulic cylinder, etc., and can be set according to actual needs, all of which are within the scope of protection of this application.

[0077] In addition, the aforementioned hoisting and moving device also includes a lateral moving support 66, which is located at the bottom of the accommodating space and can support the welding equipment 2. The longitudinal ends of the lateral moving support 66 are respectively provided with second lateral sliding members 661, and the bottom of the vehicle body 61 is provided with a second lateral sliding groove 615 extending laterally. The second lateral sliding members 661 cooperate with the second lateral sliding groove 615. The second lateral sliding members 661 and the second lateral sliding groove 615 can be configured with reference to the first lateral sliding member 643 and the first lateral sliding groove 614.

[0078] The lateral moving support 66 is located vertically at the bottom of the accommodating space and can support the welding equipment 2. During operation, the boom 22 of the turnout rail welding vehicle lifts the welding equipment 2 onto the lateral moving support 66 and then retracts the boom 22. By driving the lateral moving support 66 to move, the welding equipment 2 first moves to the vicinity of the preset welding position, and then drives the lateral power drive component 642 to move, causing the lateral moving mounting base 641, its longitudinal moving component 65, and the vertical lifting component 63 to move together to correspond with the lateral moving support 66. The vertical lifting component 63 supports the lateral moving support 66. The welding equipment 2 is lifted, and at the same time, the lateral moving support 66 retracts and separates from the welding equipment 2, making way for subsequent welding operations. The vertical lifting assembly 63 then lifts the welding equipment 2 to perform the welding operation. After the operation is completed, when moving to the next welding operation position, the lateral moving support 66 is driven to move to the position opposite to the lifted welding equipment 2, and the vertical lifting assembly 63 drives the welding equipment 2 to sit on the lateral moving support 66. Then, the trolley traveling device is driven to move to the next welding operation position to reduce collisions of the welding equipment 2 during the movement and improve the stability of the device.

[0079] Specifically, the vehicle body 61 is a cuboid frame, which includes a top support frame 611, a bottom support frame 612, and several vertical beams 613. The top support frame 611 and the bottom support frame 612 are arranged vertically and parallel to each other. The top support frame 611 and the bottom support frame 612 are both rectangular frame structures, and the top support frame 611 and the bottom support frame 612 have the same structure. The vertical ends of each vertical beam 613 are connected to the top support frame 611 and the bottom support frame 612 respectively, such as by threaded fixing. The top support frame 611 and the bottom support frame 612 each include two sets of parallel horizontal beams 6111 and two sets of parallel vertical beams 6112. The horizontal beams 6111 and the vertical beams 6112 are fixedly connected, and the horizontal beams 6111 and the vertical beams 6112 are connected end to end to form a rectangular frame structure. Preferably, the top support frame 611 has two sets of crossbeams 6111 respectively provided with first transverse sliding grooves 614 for installing transverse moving mounting bases 641; the bottom support frame 612 has two sets of crossbeams 6111 respectively provided with second transverse sliding grooves 615 for installing transverse moving supports 66.

[0080] Based on the above embodiments, the transfer trolley 6 further includes two sets of auxiliary support devices 67. The two sets of auxiliary support devices 67 are located at the transverse ends of the vehicle body 61, and each set includes at least two auxiliary support devices 67 arranged longitudinally along the vehicle body 61. The fixed ends of the auxiliary support devices 67 are fixed to the vehicle body 61, and the moving ends of the auxiliary support devices 67 are in contact with the ground. The auxiliary support devices 67 can extend and retract vertically to support the vehicle body 61. Preferably, each set of auxiliary support devices 67 includes two auxiliary support devices 67, and the four auxiliary support devices 67 are respectively set on the vertical beams 613 at the top corners of the cuboid frame. The fixed ends of the auxiliary support devices 67 are fixed to the vertical beams 613, and the moving ends are in contact with the ground. The auxiliary support devices 67 can synchronously drive the vehicle body 61 to move upwards or downwards; the extension distance of the auxiliary support devices 67 can also be controlled according to the ground terrain to support the vehicle body 61, ensuring the levelness of the vehicle body 61 and improving the stability of the device. Specifically, the auxiliary support device 67 includes a lifting cylinder and a support leg.

[0084] In one specific implementation, the operation process of the aforementioned turnout rail welding vehicle includes:

[0085] S1: The turnout rail welding vehicle is loaded onto a flatbed car (or transport car) and transported to the vicinity of the pre-laid turnout using a Rail 100 tractor. The reinforcement lock between the turnout rail welding vehicle and the flatbed car is then released.

[0086] S2: Tooling supports are used, and the turnout rail welding vehicle uses a crawler traveling device 4 for unloading.

[0087] S3: When the turnout rail welding vehicle moves to the vicinity of the turnout, the reinforcement and locking of the transfer trolley 6 is released. The transfer trolley 6 is then lifted by the boom 22 to the pre-laid turnout location for rapid connection of cables, oil pipes, and water pipes.

[0088] S4: The transfer trolley 6 travels to the welding joint via the trolley traveling device 62. After aligning with the position, the auxiliary support device 67 is vertically adjusted and placed against the sleeper or the ground. The trolley traveling device 62 then disengages from the rail.

[0089] S5: After the welding equipment 2 is lifted by the winch, the lateral moving support 66 under the welding equipment 2 is moved away, the lateral moving component 64 is adjusted to the lateral position, the winch is lowered to the appropriate position to perform joint welding, after the welding is completed, the welding equipment 2 is lifted back to the original position, the auxiliary support device 67 is retracted, and the trolley traveling device 62 travels to the next joint position.

[0090] S6: After welding is completed, the boom 22 recovers the transfer trolley 6, the transfer trolley 6 is reinforced and locked, and the turnout rail welding operation vehicle moves to the vicinity of the flatbed car;

[0091] S7: It uses tooling supports, tracks to move onto the vehicle, and is loaded onto a flatbed truck.

[0092] S8: The turnout rail welding vehicle and flatbed car are reinforced and locked together, and then driven away from the work area by the tractor.

[0093] The turnout rail welding vehicle is not limited to being transported to the site by flatbed truck; it can also be transported by car, or, if the distance is short, by self-propelled means.

[0094] During the online pre-laying process, the turnout rail welding vehicle can travel to the vicinity of the turnout via its traveling wheels, and then perform welding via the transfer trolley 6.

[0095] During the pre-laying of the track, if the track surface is relatively firm, the turnout rail welding vehicle can travel directly to the vicinity of the welding joint using its wheels. If the wheels cannot travel directly, the vehicle can travel to the vicinity of the pre-laying location using tracks. If the turnout rail welding vehicle has difficulty traveling to the vicinity of the pre-laying location, two temporary transverse rails can be laid on-site or existing rails can be used. The transfer trolley 6 is then lifted by the boom 22 to the temporary track 100 and travels to the pre-laid turnout location.
