Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] The following is combined with Figures 1 to 6 The present invention describes a pantograph raising device and a rail vehicle according to embodiments thereof. It should be understood that the following description is merely an illustrative embodiment of the invention and does not constitute any particular limitation thereof.

[0034] An embodiment of the first aspect of the present invention provides a bow-raising device, such as... Figure 1As shown, it includes: a hand-operated cable assembly; a cable swivel 400, the middle of which is rotatably connected to the roof of the rail vehicle, and the first end of which is connected to the hand-operated cable assembly; a connecting rod 500, the first end of which is connected to the second end of the cable swivel 400; a pantograph lifting swivel 600, the first end of which is connected to the second end of the connecting rod 500, and the second end of which is rotatably connected to the roof of the rail vehicle; a pantograph lifting connecting rod 700, the first end of which is rotatably connected to the middle of the pantograph lifting swivel 600; and a pantograph hook, which is rotatably connected to the roof and the second end of the pantograph lifting connecting rod 700.

[0035] The pantograph raising device provided by this invention includes a hand-operated cable assembly, a cable rotating rod 400, a connecting rod 500, a pantograph raising rotating rod 600, a pantograph raising connecting rod 700, and a pantograph hook. The middle portion of the cable rotating rod 400 is rotatably connected to the roof of the rail vehicle. The middle portion of the cable rotating rod 400 refers to the part located between the first and second ends of the cable rotating rod 400. The first end of the cable rotating rod 400 is rotatably connected to the hand-operated cable assembly, and the second end of the cable rotating rod 400 is rotatably connected to the first end of the connecting rod 500. The second end of the connecting rod 500 is rotatably connected to the first end of the pantograph raising rotating rod 600, and the second end of the pantograph raising rotating rod 600 is rotatably connected to the roof of the rail vehicle. One end of the pantograph raising connecting rod 700 is rotatably connected to the middle portion of the pantograph raising rotating rod 600. The middle portion of the pantograph raising rotating rod 600 refers to the part located between the first and second ends of the pantograph raising rotating rod 600. The other end of the lifting rod 700 is connected to the pantograph hook.

[0036] During the raising of the bow, the manual pull cable assembly is manually pulled, which drives the cable lever 400 to rotate. During the rotation of the cable lever 400, the raising lever 600 can be driven to rotate through the connecting rod 500. In turn, the raising lever 600 rotates and pulls the raising connecting rod 700 to move, so that the raising connecting rod 700 drives the pantograph hook to flip and unlock.

[0037] As described above, the manual pantograph raising mechanism, achieved through a purely mechanical transmission structure, completely eliminates the reliance on compressed air and external power. This not only enables rapid and reliable pantograph raising in the absence of electricity or in the event of air leaks, greatly enhancing the vehicle's emergency response capabilities and operational reliability, but also simplifies the system structure, reduces maintenance frequency and costs due to air component failures, and offers convenient operation and wide applicability. This effectively improves the redundancy, safety, and environmental adaptability of the entire pantograph raising system.

[0038] In one embodiment of the present invention, the hand-operated cable assembly includes: an in-vehicle cable structure 100, the first end of which is disposed inside the rail vehicle; an out-of-vehicle cable structure 200, the first end of which is disposed outside the rail vehicle; and an intermediate connecting portion 300, the first end of which is connected to the second end of both the in-vehicle cable structure 100 and the second end of the out-of-vehicle cable structure 200, and the second end of which is connected to the first end of a cable rotating rod 400.

[0039] like Figure 1 , Figure 4 and Figure 5 As shown, an internal cable structure 100 is installed inside the rail vehicle, and an external cable structure 200 is installed outside the rail vehicle. Both the internal cable structure 100 and the external cable structure 200 are positioned in a safe and easily accessible location for operators. Both the internal cable structure 100 and the external cable structure 200 are connected to the first end of an intermediate connecting part 300, and the second end of the intermediate connecting part 300 is connected to the first end of a cable rotating rod 400. In other words, both the internal cable structure 100 and the external cable structure 200 can drive the cable rotating rod 400 to rotate via the intermediate connecting part 300 to perform corresponding pantograph raising operations.

[0040] In one embodiment of the present invention, the intermediate connecting part 300 includes: a fixed seat 310, which is connected to the roof of the rail vehicle; and a sliding connector 320, the first end of which is slidably connected to the fixed seat 310, and the second end of which extends from the fixed seat 310 to the outside of the fixed seat 310 and is connected to the first end of the cable rotating rod 400.

[0041] Both the in-vehicle cable structure 100 and the out-of-vehicle cable structure 200 are connected to the first end of the sliding connector 320.

[0042] For example, such as Figure 2 and Figure 3 As shown, the fixed base 310 includes an outer base plate 311 and an inner base plate 312.

[0043] The outer base plate 311 is fixedly connected to the roof of the rail vehicle, and the inner base plate 312 is fitted to the upper side of the outer base plate 311.

The first end of the connecting screw 325 extends into the interior of the fixed seat 310 through the guide groove 314, so that the slider 321 is placed on the inner base plate 312 and can slide relative to the inner base plate 312. The second end of the connecting screw 325 and the connecting block 322 are located outside the fixed seat 310. The second end of the connecting screw 325 can be rotatably connected to the first end of the cable rotating rod 400. The first limiting rod 323 and the second limiting rod 324 are located on both sides of the connecting screw 325, both parallel to the connecting screw 325, and both the first limiting rod 323 and the second limiting rod 324 are limited and supported between the slider 321 and the connecting block 322. The in-vehicle cable structure 100 and the out-of-vehicle cable structure 200 can both be connected to the slider 321. Thus, both the in-vehicle cable structure 100 and the out-of-vehicle cable structure 200 can drive the slider 321 to slide on the inner bottom plate 312, and then the slider 321 drives the cable rotating rod 400 to rotate through the connecting screw 325.

[0044] An insulator 340 can also be installed between the second end of the connecting screw 325 and the first end of the cable rotating rod 400. A grounding wire 330 can be connected to the connecting block 322.

[0045] The mounting base 310 may also include an outer cover 313, which is connected to the outer base plate 311 and can cover the components connected to the outer base plate 311.

[0046] In one embodiment of the present invention, the in-vehicle cable structure 100 includes: an in-vehicle protective box 110, which is fixed to the interior of the rail vehicle; a first protective tube 120, which is connected to the in-vehicle protective box 110, with a first end of the first protective tube 120 located outside the in-vehicle protective box 110 and a second end of the first protective tube 120 extending from the outside of the in-vehicle protective box 110 to the interior of the in-vehicle protective box 110; an in-vehicle handle 130; and an in-vehicle pull rope 140, with a first end of the in-vehicle pull rope 140 extending through the first protective tube 120 into the in-vehicle protective box 110 and connecting with the interior of the rail vehicle. A handle 130 is connected, and the interior handle 130 can be limited to the second end of the first protective tube 120. The second end of the interior pull rope 140 is connected to the first end of the sliding connector 320. An interior locking structure 150 is connected between the interior handle 130 and the second end of the first protective tube 120. A second protective tube 160 is connected to the first end of the fixing seat 310. A connecting tube 170 is connected to the second end of the second protective tube 160. A horn tube 180 is connected to the second end of the connecting tube 170. The second end of the interior pull rope 140 passes through the horn tube 180, the connecting tube 170, and the second protective tube 160 in sequence from the large end of the horn tube 180 and is connected to the fixing seat 310.

[0047] Combination Figures 1 to 4 Specifically, the mounting base 310 also includes a protective tube fixing plate 315. The first end of the second protective tube 160 is fixedly connected to the protective tube fixing plate 315, the second end of the second protective tube 160 is connected to the first end of the connecting tube 170, and the second end of the connecting section is connected to the small end of the horn tube 180. For example, the second protective tube 160 can extend from the outside of the roof of the rail vehicle to the inside of the vehicle, and both the connecting tube 170 and the horn tube 180 are located inside the vehicle. The interior protection box 110 is fixed at a suitable position inside the vehicle. A flip door is provided on the front side of the interior protection box 110. The middle of the first protective tube 120 is provided with threads, and the top surface of the interior protection box 110 is provided with threaded holes. The second end of the first protective tube 120 can extend into the interior protection box 110 through the threaded holes, the middle of the first protective tube 120 is threadedly connected to the top surface of the interior protection box 110, and the first end of the first protective tube 120 is located on the outside of the top surface of the interior protection box 110. The first end of the interior pull cord 140 passes through the first protective tube 120 and extends into the interior protection box 110, connecting to the interior handle 130. The second end of the interior pull cord 140 passes sequentially through the horn tube 180, the connecting tube 170, and the second protective tube 160, connecting to the slider 321. The interior handle 130 is positioned at the second end of the first protective tube 120. Operators can open the flip-top door and pull the interior pull cord 140 using the interior handle 130, causing the interior pull cord 140 to drive the slider 321 to slide. When the slider 321 returns to its original position, the interior handle 130 is positioned at the second end of the first protective tube 120.

[0048] Furthermore, an interior locking structure 150 can be provided between the interior handle 130 and the second end of the first protective tube 120. For example, the locking structure may include a locking cord and a magnetic snap, with one end of the locking cord connected to the second end of the first protective tube 120. The magnetic snap is disposed between the other end of the locking cord and the interior handle 130.

[0049] When no pantograph raising operation is required, the flip-top door can be locked, and the locking rope is locked between the first protective tube 120 and the interior handle 130. When pantograph raising operation is required, the flip-top door can be opened and the locking rope unlocked to operate the interior handle 130.

[0050] In one embodiment of the present invention, the external cable structure 200 includes: an external protective seat 210, which is connected to the outer side of the rail vehicle and has a protective groove; a third protective tube 220, which is connected to the external protective seat 210, with its first end located outside the external protective seat 210 and its second end passing through the external protective seat 210 into the protective groove; an external handle 230; and an external cable 240, the first end of which passes through the third protective tube 220.

[0053] The connection ends of the first rotating rod body 410 and the second rotating rod body 420 are rotatably connected to the roof of the rail vehicle.

[0054] Furthermore, in one embodiment of the present invention, the pantograph raising device further includes: a limiting seat 900, which is connected to the roof of the rail vehicle and is located beside the second end of the connecting rod 500; and a limiting strip groove 910, which extends to the limiting seat 900.

[0055] The first end of the lifting rod 600 is connected to the second end of the connecting rod 500, and the second end of the lifting rod 600 passes through the limiting strip groove 910 and is connected to the limiting seat 900.

[0056] Specifically, Figure 1 ,like Figure 2 and Figure 6 As shown, in this embodiment, the second end of the first rotating rod body 410 is connected to the first end of the second rotating rod body 420, forming a V-shaped rod structure. The connecting ends of the first rotating rod body 410 and the second rotating rod body 420 are rotatably connected to the roof of the rail vehicle via a connecting seat 430. The first end of the first rotating rod body 410 is rotatably connected to the second end of the connecting screw 325. The first end of the connecting rod 500 is rotatably connected to the second end of the second rotating rod body 420. A limiting seat 900 is disposed beside the second end of the connecting rod 500. A limiting groove 910 is provided on the limiting seat 900. For example, the setting direction of the limiting groove 910 is parallel to the moving direction of the connecting rod 500. The lifting rod 600 is a straight rod structure. The first end of the lifting rod 600 is rotatably connected to the second end of the connecting rod 500, and the second end of the lifting rod 600 passes through the limiting groove 910 and is rotatably connected to the limiting seat 900. The first end of the lifting rod 700 is rotatably connected to the middle of the lifting rod 600. The middle of the lifting rod 600 refers to the portion between the first and second ends of the lifting rod 600. For example, the middle of the lifting rod 600 is located between the second end of the lifting rod 600 and the limiting groove 910. The limiting groove limits the rotation range of the lifting rod 600, and consequently, limits the movement range of the lifting rod 700, ensuring smooth unlocking of the pantograph hook without excessive overturning of the pantograph hook. Furthermore, an insulator 340 can also be connected to the lifting rod 700.

[0057] In one embodiment of the present invention, the pantograph lifting device further includes: an elastic reset structure 800, one end of which is connected to the roof of the rail vehicle, and the other end of which is connected to the connecting rod 500. The elastic reset direction of the elastic reset structure 800 is opposite to the movement direction of the connecting rod 500 when the pantograph is unlocked.

[0058] Furthermore, in one embodiment of the present invention, the elastic reset structure 800 includes: a first connecting seat 810, which is connected to the roof of the rail vehicle; a second connecting seat 820, which is connected to the connecting rod 500; and a reset spring 830, which is connected between the first connecting seat 810 and the second connecting seat 820, wherein the elastic reset direction of the reset spring 830 is opposite to the movement direction of the connecting rod 500 when the pantograph is unlocked.

[0059] Combination Figure 6Specifically, the connecting rod 500 can be divided into a first connecting section 510 and a second connecting section 520, which are connected by a threaded connector 530. For example, the second connecting section 520 has a limiting section 521 with external threads. Two limiting nuts 522 are connected at intervals on the limiting section 521. The second connecting seat 820 has an inverted U-shaped structure, is hooked onto the limiting section 521, and is limited between the two limiting nuts 522. A first fixing rod is connected to the open end of the second connecting seat 820. The first fixing rod is used to connect one end of the return spring 830.

[0060] The first connecting seat 810 includes a U-shaped seat and a fixing ear. The U-shaped seat is connected to the fixing ear, which is used to connect to the roof of the rail vehicle. A through-slot is formed on the U-shaped seat, through which the second connecting section 520 passes. A limit support rod is also provided within the through-slot, perpendicular to the second connecting section 520, and the second connecting section 520 is limited to the space between the limit support rod and the wall of the through-slot. The first connecting seat 810 also includes a connecting ear, on which a second fixing rod is connected. The second fixing rod is used to connect the other end of a return spring 830. The return spring 830 is parallel to the connecting rod 500.

[0061] During pantograph raising, workers pull the corresponding cable using the inside handle 130 or the outside handle 230, causing the slider 321 to slide within the fixed base 310. The slider 321 drives the cable rotating rod 400 to rotate via the sliding connector 320, which in turn pulls the connecting rod 500 to move. This causes the connecting rod 500 to overcome the spring force of the return spring 830 and drive the pantograph raising rod 600 to rotate. The pantograph raising rod 600 can then drive the pantograph raising connecting rod 700 to move, causing the pantograph hook to flip and unlock. When the inside handle 130 or the outside handle 230 is released, the return spring 830 pulls the connecting rod 500 in the opposite direction, ultimately causing the pantograph hook to lock and reset.

[0062] A second aspect of the present invention provides a rail vehicle including the pantograph lifting device as described above.

[0063] Furthermore, the rail vehicle provided by the present invention, since it includes the pantograph lifting device as described above, also possesses the advantages described above.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
