[0050] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0051] The existing support device is used to be configured on the track collecting device, and two independent support rods are fixed on the telescopic arm of the track collecting device. Two rollers are provided at the lower ends of the two independent support rods, and the two rollers are installed on the same wheel axle. Driven by the wheel axle, the two rollers move together until they dock with the rails. During the specific operation, when the track collecting device extends the long rail car to form a cantilever structure, the two independent support rods fixed on the telescopic arm are hydraulically driven to vertically extend and retract on the telescopic arm, driving the rollers to move in the vertical direction, and then dock with the rails, completing the support of the telescopic arm of the track collecting device and ensuring the normal operation of the cantilever structure of the track collecting device.

[0052] However, when the long rail vehicle is operating on a curved section of the rail, the long rail vehicle stops on the curved rail, and the rail collecting device extends in a straight line along the long rail vehicle stop position, that is, extends along the tangent direction of the curved rail, thereby driving the supporting device to move along the tangent direction of the curved rail, causing the supporting device to deviate from the rail and unable to stably support the rail collecting device.

[0053] To address the aforementioned issues, the present application provides a rail collecting vehicle working arm and a rail collecting vehicle. During rail recovery operations using the rail collecting vehicle, the working arm of the rail collecting vehicle is disposed on the vehicle body. A support device disposed on the working arm body of the rail collecting vehicle, under the control of a controller and a solenoid valve, drives a hydraulic circuit to drive a first drive unit and a second drive unit, further driving the support assembly to telescope onto the rails, thereby stably supporting the working arm body. Thus, when operating on curved rails, the support device of the working arm of the rail collecting vehicle is fixed to the curved rails, providing stable support and facilitating operations on the curved rails. Furthermore, the addition of a synchronization circuit to the hydraulic circuit prevents the two arms from becoming out of sync or jamming during telescoping.

[0054] The specific contents of the present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0055] When using a rail collecting vehicle for rail recovery operations, the rail collecting device needs to be extended out of the vehicle to form a cantilever structure for operation, and a support device needs to be configured on the cantilever structure to ensure the stability of the cantilever structure. The existing support device is used to be configured on the rail collecting device, and two independent support rods are used to be fixed on the telescopic arm of the rail collecting device. When operating on curved rails, the rail collecting device extends out of the vehicle body and drives the support device to move along the tangent direction of the curved rail, so that the support device deviates from the rail. The working arm of the rail collecting vehicle and the support device of the rail collecting vehicle of this scheme can be telescopically moved and fixed on the curved rail, which can provide stable support and facilitate operations on curved rails.

[0056] Figure 1 This is a schematic diagram of the connection structure of a working arm of a rail collecting vehicle provided by an embodiment of the present invention. Figure 1As shown, the rail collecting vehicle 200 includes a vehicle body 210 and a working arm 100. During the rail collecting operation, the working arm 100 is extended from the rail collecting vehicle 200. During the rail transportation process, the working arm 100 is retracted from the rail collecting vehicle 200. Figure 2 for Figure 1 The schematic diagram of the structure of the rail collecting vehicle with the working arm shortened. Figure 2 As shown, the working arm 100 of the rail collecting vehicle includes a working arm body 110 and a supporting device 120. The supporting device 120 is arranged on the working arm body 110. When the working arm 100 of the rail collecting vehicle is extended out of the rail collecting vehicle 200 to perform rail recovery operations, the supporting device 120 is telescopically moved to the rail to support the working arm body 110. The supporting device 120 has a supporting assembly 121 and a driving assembly 122. The driving assembly 122 is used to drive the supporting assembly 121 to telescopically move to the rail. The supporting assembly 121 includes a supporting wheel unit 123 and two retractable support arms 124. The two support arms 124 are respectively arranged on opposite sides of the working arm body 110, and the support arms 124 are fixedly connected to the working arm body 110. Under the drive of the driving assembly 122, the support arms 124 are synchronously extended or shortened in the vertical direction. Figure 3 for Figure 2 The left side view of the working arm of the rail collecting vehicle. Figure 3 As shown, the support wheel unit 123 includes a connecting frame 1231 and a support wheel 1232 arranged on the connecting frame 1231. Under the drive of the driving assembly 122, the support wheel 1232 is horizontally moved relative to the connecting frame 1231 along the axial direction of the support wheel 1232. The bottom ends of the two support arms 124 are connected to the connecting frame 1231, so that when the support arms 124 are synchronously extended or shortened in the vertical direction, the support wheel unit 123 is driven to move in the vertical direction. The driving assembly 122 includes a first driving unit 1221 and a second driving unit 1222. The first driving unit 1221 is connected to the two support arms 124 for driving the two support arms 124 to synchronously extend or shorten in the vertical direction. The second driving unit 1222 It is connected to the connecting frame 1231 and is used to drive the support wheel 1232 to move horizontally relative to the connecting frame 1231 along the axial direction of the support wheel 1232. Specifically, when operating on a curved rail, the body 210 of the track collecting vehicle 200 stops on the curved rail, and the working arm body 110 extends out of the body 210 and drives the support device 120 to move along the tangent direction of the curved rail, so that the support device 120 deviates from the rail. Through the drive of the first drive unit 1221 and the second drive unit 1222, the support wheel 1232 is extended and retracted in the vertical direction and moved in the horizontal direction until it docks with the deviated rail, so that the support device 120 of the working arm 100 of the track collecting vehicle is fixed on the curved rail, stably supported, and convenient for operation on the curved rail.

[0057] Optionally, the support assembly 121 is provided with two support arms 124, namely a first support arm 1241 and a second support arm 1242. The first support arm 1241 and the second support arm 1242 are of the same size and are symmetrically arranged relative to the working arm body 110. The first support arm 1241 and the second support arm 1242 are respectively arranged on opposite sides of the working arm body 110, and the first support arm 1241 and the second support arm 1242 are fixedly connected to the working arm body 110. The first support arm 1241 and the second support arm 1242 are controlled by the same hydraulic circuit 130 to achieve synchronous extension or shortening of the first support arm 1241 and the second support arm 1242 in the vertical direction under the drive of the drive assembly 122, thereby avoiding the phenomenon of the two support arms 124 being out of sync and stuck during the extension and retraction process.

[0058] Figure 4 This is a structural diagram of a working arm of a rail collecting vehicle provided by an embodiment of the present invention, as shown in FIG. Figure 4 As shown, the first driving unit 1221 includes two first hydraulic cylinders 1225, and the two first hydraulic cylinders 1225 correspond one-to-one to the first arm 1241 and the second arm 1242, and are respectively used to drive the corresponding arm 124 to extend or shorten, and the two first hydraulic cylinders 1225 are located in the same hydraulic circuit 130 and are synchronously driven by the hydraulic circuit 130, so that under the drive of the driving component 122, the first arm 1241 and the second arm 1242 are synchronously extended or shortened in the vertical direction, thereby avoiding the phenomenon of the two arms 124 being out of sync and stuck during the extension and retraction process.

[0059] Since the first support arm 1241 and the second support arm 1242 are of the same size and are symmetrically arranged relative to the working arm body 110, the two first hydraulic cylinders 1225 correspond one to one with the first support arm 1241 and the second support arm 1242. For example, taking one of the support arms 124 and the first hydraulic cylinder 1225 as an example, the support arm 124 includes an outer support arm sleeve 1243 and an inner support arm shaft 1244. The outer support arm sleeve 1243 is used to connect with the working arm body 110 to fix the support arm 124. The outer support arm sleeve 1243 has a hollow sliding cavity 1245. The inner support arm shaft 1244 is slidably arranged in the sliding cavity 1245. Under the drive of the drive assembly 122, the inner support arm The arm shaft 1244 can be synchronously extended or shortened in the vertical direction along the sliding cavity 1245 of the outer arm sleeve 1243. The bottom end of the inner arm shaft 1244 is connected to the connecting frame 1231, so that when the inner arm shaft 1244 is synchronously extended or shortened in the vertical direction, it drives the connecting frame 1231 to move in the vertical direction, and then drives the support wheel unit 123 to move in the vertical direction. The first hydraulic cylinder 1225 is connected between the inner arm shaft 1244 and the outer arm sleeve 1243, and is used to drive the inner arm shaft 1244 to slide in the vertical direction relative to the outer arm sleeve 1243 along the sliding cavity 1245 of the outer arm sleeve 1243, so that the arm 124 can be extended or shortened.

[0060] In an optional embodiment, the cross-section of the inner arm shaft 1244 and the cross-section of the sliding cavity 1245 are both circular, and the side wall of the inner arm shaft 1244 and the cavity wall of the sliding cavity 1245 are tightly fitted. The inner arm shaft 1244 can be easily extended or shortened in the vertical direction along the sliding cavity 1245 of the outer arm sleeve 1243, which can reduce the phenomenon of asynchrony and jamming of the two arms 124 during the extension and retraction process.

[0061] Optionally, the support wheel unit 123 further includes an axle 1233, which is movably arranged on the connecting frame 1231. On the one hand, the support wheel 1232 can be fixed so that the support wheel 1232 can be docked with the rail, thereby supporting the working arm body 110. On the other hand, under the drive of the driving assembly 122, the support wheel 1232 can be horizontally moved along the axial direction of the axle 1233 of the support wheel 1232 relative to the connecting frame 1231. Specifically, the axle 1233 is arranged on the connecting frame 1231, the support wheel 1232 is arranged on the axle 1233, and the second driving unit 1222 is connected between the connecting frame 1231 and the axle 1233. It is used to drive the wheel axle 1233 to move axially along the wheel axle 1233 relative to the connecting frame 1231. When operating on a curved rail, the track collecting vehicle 200 stops on the curved rail, and the working arm body 110 extends out of the vehicle body 210, driving the support device 120 to move along the tangential direction of the curved rail, so that the support device 120 deviates from the rail. Through the drive of the second drive unit 1222, the support wheel 1232 is moved horizontally along the axial direction of the wheel axle 1233 of the support wheel 1232 relative to the connecting frame 1231 until it docks with the deviated rail, so that the support device 120 of the working arm 100 of the track collecting vehicle is fixed on the curved rail, stably supported, and convenient for operation on the curved rail.

[0062] Optionally, the connecting frame 1231 has an axial hole 1234 with openings at both ends, the wheel axle 1233 is passed through the axial hole 1234, and the end of the wheel axle 1233 extends out of the axial hole 1234, and the support wheel 1232 is arranged at the end of the wheel axle 1233. Specifically, the axial hole 1234 with openings at both ends has the same axis as the wheel axle 1233, and the two axial holes 1234 have the same size, so that the wheel axle 1233 can move inside the two axial holes 1234, thereby driving the support wheel 1232 arranged at the end of the wheel axle 1233 to move horizontally along the axial direction of the support wheel 1232 relative to the connecting frame 1231, wherein the distance between the two support wheels 1232 is consistent with the distance between the rails, so that the support wheel 1232 is docked with the rails to support the working arm body 110.

[0063] Optionally, the second driving unit 1222 includes a second hydraulic cylinder 1226, one end of which is connected to the connecting frame 1231, and the other end is connected to the wheel axle 1233, for driving the wheel axle 1233 to move axially along the wheel axle 1233 relative to the connecting frame 1231. When operating on a curved rail, the track collecting vehicle 200 stops on the curved rail, and the working arm body 110 extends out of the vehicle body 210, driving the support device 120 to move along the tangential direction of the curved rail, so that the support device 120 deviates from the rail. Through the drive of the second hydraulic cylinder 1226, the support wheel 1232 is moved horizontally along the axial direction of the wheel axle 1233 of the support wheel 1232 relative to the connecting frame 1231 until it docks with the deviated rail, thereby achieving the goal of fixing the support device 120 of the working arm 100 of the track collecting vehicle on the curved rail, providing stable support, and facilitating operation on the curved rail.

Figure 5 As shown, the drive assembly 122 includes a controller 1223 and a solenoid valve 1224. The controller 1223 and the solenoid valve 1224 are electrically connected. The solenoid valve 1224 is connected to the hydraulic circuit 130 where the first hydraulic cylinder 1225 is located. The solenoid valve 1224 is configured to be fixed on the working arm body 110. Specifically, under the control of the controller 1223 and the solenoid valve 1224, the hydraulic circuit 130 is driven to drive the first hydraulic cylinder 1225 and the second hydraulic cylinder 1226. Since a synchronization circuit 131 is provided in the hydraulic circuit 130, it can ensure that the two first hydraulic cylinders 1225 operate synchronously. The two first hydraulic cylinders 1225 and the second hydraulic cylinders 1226 are driven synchronously. The cylinder 1225 synchronously drives the first arm 1241 and the second arm 1242 to extend or shorten synchronously in the vertical direction, thereby driving the support wheel unit 123 to move in the vertical direction. Driven by the second hydraulic cylinder 1226, the support wheel 1232 arranged at the end of the wheel axle 1233 is driven to move horizontally along the axial direction of the support wheel 1232 relative to the connecting frame 1231. With the cooperation of vertical extension and contraction and horizontal movement, the support wheel 1232 is docked with the deviated rail, so that the support device 120 of the working arm 100 of the rail collecting vehicle is fixed on the curved rail, providing stable support and facilitating operation on the curved rail.

After the working arm body 110 is extended out of the vehicle body 210, it drives the support device 120 to move along the tangent direction of the curved rails, so that the support device 120 deviates from the rails. Through the drive of the second hydraulic cylinder 1226, the support wheel 1232 is horizontally moved along the axial direction of the wheel axle 1233 of the support wheel 1232 relative to the connecting frame 1231 until it docks with the deviated rails, so that the support device 120 of the working arm 100 of the rail collecting vehicle is fixed on the curved rails, stably supported, and convenient for operation on the curved rails.
