Description

TECHNICAL FIELD

[0001] The utility model relates to a current collector for rail transit vehicle, in particular to a current collector device for rail vehicle. BACKGROUND

[0002] The current collector for rail transit vehicle obtains electric energy by contacting with the power rail through the sliding block, and the obtained electric energy is provided to the train through the cable after passing through the fuse box, thereby realizing the power supply of the whole train.

[0003] Chinese patent CN115320393A discloses a side current collector lifting device for urban rail vehicle, which adopts a mechanical structure. When the urban rail vehicle needs to be parked and powered off during operation on the line, the operator manually pulls the lifting shoe handle in the vehicle, transmits the force through the lifting shoe insulating rope, and under the action of the lifting shoe insulating rope, the connecting plate connected therewith rotates to drive the upper arm rod to rotate, so that the sliding plate of the current collector is separated from the power rail. Under the action of the lifting shoe insulating rope, the connecting plate connected therewith rotates to release the constraint of the locking hook on the sliding plate shaft of the current collector, so that the sliding plate of the current collector contacts the power rail. Such a side current collector lifting device needs to cross the power rail to operate the lifting shoe of the opposite side current collector, and needs to directly operate the live part of the current collector, which has a high safety risk, especially in rainy and snowy weather. In addition, this kind of manual mechanical current collector needs to be equipped with an insulating rod on the vehicle, in case of emergency, the sliding plate is separated from the power rail by operating the upper arm rod shaft through the insulating rod, which makes it necessary to set a special insulating rod storage area in the vehicle, and the insulating rod is easy to lose and inconvenient to use. SUMMARY

[0004] The technical problem to be solved by the utility model is that the existing current collector needs to cross the power rail to operate the opposite side current collector. The utility model provides a rail vehicle current collector device which can operate the current collector without crossing the power rail.

[0005] To solve the above technical problems, the utility model adopts the following technical scheme:

[0006] A rail vehicle current collector device, comprising a current collector and a lifting shoe device, the current collector is connected to the lifting shoe device, and the current collector is installed on one side of the bogie, and the lifting shoe device is installed on the other side of the bogie.

[0007] The current collector of this utility model is installed on one side of the bogie, and the lifting shoe device is installed on the other side of the bogie. In this way, the operator can operate the current collector without crossing the power supply rail. The current collector on the operator's side can be operated by directly rotating the bow head shaft of the current collector using the insulating rod, or the current collector on the opposite side of the bogie can be remotely operated through the lifting shoe device installed on the operator's side. The operation is safe, efficient, labor-saving, and easy to operate.

[0008] Preferably, the plurality of the current collectors are arranged symmetrically on the bogie.

[0009] Preferably, the current receiver includes a bow head for receiving current in contact with the power supply rail, a base frame for mounting the bow head, a bow head shaft for rotatably connecting the bow head to the base frame, and a hook for locking the bow head shaft.

[0010] Preferably, the current receiver further includes a support plate, a pull rod, a spring, a frame shaft, and a frame. The frame shaft is rotatably mounted on the base frame. The frame shaft is fixedly connected to one end of the support plate, and the other end of the support plate is connected to the second insulating rod of the lifting shoe device. The frame shaft is fixedly connected to one end of the frame, and the other end of the frame is hinged to the bow head via the bow head pivot. The pull rod is hinged between the base frame and the bow head. The frame, pull rod, base, and bow head constitute a four-bar linkage. A spring is installed between the support plate and the base frame. The hook is rotatably mounted on the base frame.

[0011] Preferably, the lifting shoe device includes a first insulating rod, a second insulating rod, a lifting shoe wire rope, a lowering shoe wire rope, a lifting shoe handle, and a lowering shoe handle. The lifting shoe handle is connected to one end of the first insulating rod via the lifting shoe wire rope, and the other end of the first insulating rod is connected to the hook for controlling the current receiver to disengage and lift the shoe. The lowering shoe handle is connected to one end of the second insulating rod via the lowering shoe wire rope, and the other end of the second insulating rod is connected to the support plate on the current receiver for lowering the current receiver. Thus, this invention utilizes the lifting shoe handle and the lowering shoe handle to control the lifting and lowering of the current receiver on the opposite side of the bogie. The built-in first and second insulating rods enable the lifting and lowering of the current receiver on the corresponding side, providing high safety and reliability, as well as being labor-saving and easy to operate. Furthermore, this invention's lifting shoe device is equipped with a first insulating rod and a second insulating rod for lifting shoe operation, avoiding the need for additional insulating rods on the vehicle and the associated problems.

[0012] Preferably, the lifting shoe wire rope and the lowering shoe wire rope are fixed to the bogie by supports and fixing clamps.

[0013] Preferably, the raising shoe handle and the lowering shoe handle are fixed to the bogie via a fixing seat, and the raising shoe handle is detachably connected to the raising shoe safety bolt, and the lowering shoe handle is detachably connected to the lowering shoe safety bolt.

[0014] Preferably, the current collector is mounted on the bogie via an insulating base.

[0015] Preferably, the support plate and frame shaft of the current receiver of this utility model are connected by a ratchet mechanism, and there is an included angle of 25-45 degrees (preferably 30 degrees) between the support plate and the frame shaft. When the bow head shaft is directly operated to move freely up and down through the insulating rod, it will not affect the support plate, that is, it will not affect the manual control of the lifting shoe operation of the current receiver. The lifting shoe function can also be realized by pulling the lifting shoe handle or the lowering shoe handle separately, thus isolating the current receiver.

[0016] This invention uses a spring to provide contact force between the receiver head and the power supply rail. It also adopts a detachable hook design, which can lock the receiver in the lowered shoe position. After the receiver is unhooked, the receiver head rises to the working position and contacts the power supply rail to supply power under the action of the spring force itself.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This utility model of a current-collecting device not only realizes the function of train current collection, but also structurally avoids the risk of electric shock associated with mechanical current collectors that use insulated rods to operate the current collector's lifting and lowering. This invention relates to a current collector for urban rail vehicles, featuring a remotely operable current collector lifting shoe device. Specifically, it is a vehicle current-collecting device, where the current collector employs a locking structure, enabling both manual lifting and lowering of the shoe and remote operation of the current collector's lifting and lowering.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] like Figure 1 , Figure 2As shown, the current receiving device of this utility model mainly consists of a current receiver 2 and a lifting shoe device 1. The current receiver 2 is connected to the outer side of the bogie 24 through an insulating base 9, and the current receivers 2 are arranged symmetrically on the bogie. Each current receiver 2 is equipped with a corresponding lifting shoe device 1, which is used to control the lifting shoe of the current receiver 2. The current receiver 2 is installed on one side of the bogie 24, and the lifting shoe device 1 is fixed to the bottom of the other side of the bogie 24 through a support 16, a fixing seat 23, and a fixing clamp.

[0031] like Figure 3 As shown, the current collector 2 mainly consists of a bow head 3, a support plate 4, a hook 5, a pull rod 6, a base frame 7, a spring 8, an insulating base 9, a frame shaft 10, a frame 11, and a bow head rotating shaft 12. The sliding plate on the bow head 3 contacts the power supply rail to collect current. The support plate 4 and the frame shaft 10 cooperate to form a ratchet mechanism, with a 30-degree angle between them. The frame shaft 10 is fixedly connected to one end of the frame 11, and the other end of the frame 11 is hinged to the bow head 3. When the support plate 4 rotates, it drives the frame shaft 10 and the frame 11 to rotate together. The frame 11, pull rod 6, base 7, and bow head 3 constitute a four-bar linkage. One end of the support plate 4 is hinged to the base 7 via the frame shaft 10, and the other end is hinged to the second insulating rod 14 of the lifting shoe device 1. One end of the pull rod 6 is hinged to the base 7, and the other end is hinged to the bow head 3. The current collector 2 is insulated from the bogie 24 via the insulating base 9, and the base frame 7 is bolted to the insulating base 9. One end of the spring 8 is connected to the support plate 4, and the other end is fixed to the base frame 7. During the shoe raising process, the spring 8 provides the shoe raising force to the frame 11 and the support plate 4. The spring 8 is preferably connected with an M12 bolt to facilitate the adjustment of the spring length (260mm~270mm) to ensure the static contact pressure between the bow head 3 and the power supply rail. The middle part of the hook 5 is hinged to the base frame 7, and one end of the hook 5 is hinged to the first insulating rod 13 of the shoe raising device 1. Under the action of the first insulating rod 13, the hook 5 can hook the bow head shaft 12, so that the current receiver 2 is locked in the shoe lowering position.

[0032] like Figure 4As shown, the lifting shoe device 1 mainly consists of a first insulating rod 13, a second insulating rod 14, a dust cover 15, a support 16, a lifting shoe wire rope 17, a lowering shoe wire rope 18, a lifting shoe safety bolt 19, a lowering shoe safety bolt 20, a lifting shoe handle 21, a lowering shoe handle 22, and a fixed base 23. The lifting shoe handle 21 is connected to one end of the first insulating rod 13 via the lifting shoe wire rope 17, and the other end of the first insulating rod 13 is connected to the hook 5 on the current receiver 2, used to control the current receiver to disengage and lift the shoe. The lowering shoe handle 22 is connected to the second insulating rod 14 via the lowering shoe wire rope 18, and the second insulating rod 14 is connected to the support plate 4 on the current receiver 2 for lowering the current receiver. The lifting shoe wire rope 17 and the lowering shoe wire rope 18 are fixed to the bogie 24 via the support 16 and fixed clamps. To ensure that the first insulating rod 13 and the second insulating rod 14 are in a horizontal state, the fixing bolts of the support 16 need to be adjusted. The lifting shoe wire rope 17 and the lowering shoe wire rope 18 are fixed in the direction of the cable routing by the fixing clamps arranged at the bottom of the bogie 24. The fixing seat 23 fixes the lifting shoe handle 21 and the lowering shoe handle 22 to the bogie 24 on the opposite side of the current receiver 2, and the lifting shoe handle 21 is detachably connected to the lifting shoe safety bolt 19, and the lowering shoe handle 22 is detachably connected to the lowering shoe safety bolt 20.

[0033] like Figure 5 , Figure 6 As shown, when it is necessary to lower the shoe, remove the shoe lowering safety bolt 20 from the shoe lowering handle 22, pull the shoe lowering handle 22, and apply force parallel to the shoe lowering wire rope 18 until the end of the stroke of the shoe lowering wire rope 18. At this time, the shoe lowering wire rope 18 pulls the second insulating rod 14, which is connected to the support plate 4 of the current receiver 2. The support plate 4 rotates the frame shaft 10, overcoming the spring force of the spring 8 on the base frame 7 on the frame shaft 10. The frame 11 rotates with the rotation of the frame shaft 10. Since the frame 11, the pull rod 6, the base 7, and the bow head 3 form a four-bar linkage, the pull rod 6 rotates with the rotation of the frame 11, moving the bow head 3 and the bow head shaft 12 and disengaging from the power supply rail. When the bow head shaft 12 of the current receiver 2 enters the locking hook of the hook 5, the current receiver 2 is locked in the shoe lowering position, the operation stops, and the shoe lowering action is completed.

[0034] When it is necessary to raise the shoe, remove the shoe raising handle 21 and raise the shoe safety bolt 19. Pull the shoe raising handle 21 with the force direction parallel to the shoe raising wire rope 17 until the end of the stroke of the shoe raising wire rope 17. At this time, the shoe raising wire rope 17 pulls the first insulating rod 13. The first insulating rod 13 is connected to the hook 5 of the current receiver 2. When the first insulating rod 13 moves, the support plate 4 rotates the frame shaft 10 under the restoring force of the spring 8, and finally makes the hook 5 disengage from the bow head shaft 12, and the bow head 3 of the current receiver 2 reaches the shoe raising state.

[0035] It should be noted that the insulation between the current collector and the lifting shoe device of this utility model, namely the first insulating rod 13 and the second insulating rod 14, can be made by using EPGC insulating rods connected by fixing pins. Alternatively, an insulating rope can be used for connection.

[0036] The lifting shoe device 1 can be arranged at the bottom or side of the bogie, and there are multiple options for the wire rope routing, path, arrangement and fixing method of the lifting shoe device 1.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments with equivalent changes, without departing from the scope of the technical solution of this utility model. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the content of the technical solution of this utility model should fall within the protection scope of the technical solution of this utility model.
