[0027] The technical solutions of the present application will be described below in combination with Figure 1 and Figure 2 The technical solutions of the present application will be described below in combination with

[0028] The embodiments of the first aspect of the present application provide a wheel block assembly, as shown in Figure 1 and Figure 2 The technical solutions of the present application will be described below in combination with

[0029] In the wheel block assembly provided by the present application, the wheel block assembly comprises a hanging bracket 100, a containing box 200 and a wheel block 300. The hanging bracket 100 is connected to the position near the wheel set on the bogie. The containing box 200 is rotatably connected with the hanging bracket 100, so that the containing box 200 can be turned to one side close to or away from the hanging bracket 100. The wheel block 300 is placed in the containing box 200. When the wheel block 300 is needed, the containing box 200 is turned to the side away from the hanging bracket 100, so that the worker can take the wheel block 300. After use, the wheel block 300 is placed in the containing box 200, and the containing box 200 is turned to the side close to the hanging bracket 100.

[0030] As described above, the receiving box 200 containing the anti-rollover block 300 is stored on the bogie near the wheelset by the hanging bracket 100. The flip-up connection between the receiving box 200 and the hanging bracket 100 effectively overcomes the core problem of time-consuming and laborious retrieval of the anti-rollover block 300 in the prior art: the operator no longer needs to enter the carriage to find and move the anti-rollover block 300. He can quickly and conveniently retrieve or return the anti-rollover block 300 by simply flipping the receiving box 200 next to the wheelset outside the carriage. This significantly improves the efficiency of anti-rollover operation and greatly reduces the physical exertion and time cost of the operator. It is especially suitable for occasions that require frequent operation or respond to sudden anti-rollover needs.

[0031] In one embodiment of the present invention, the suspension bracket 100 includes: a suspension body 110 for connection to a position of the bogie near the wheelset; a connecting rod 120, a first end of which is connected to the suspension body 110, and a second end of which extends obliquely downward to a position on the receiving box 200 away from the suspension body 110, and the second end of which is connected to the receiving box 200 via a pivot 700, so as to press the receiving box 200 to flip the receiving box 200 away from the suspension body 110, or to release the receiving box 200 to flip the receiving box 200 towards the side of the suspension body 110.

[0032] For example, such as Figure 1 and Figure 2 As shown, the hanger body 110 is an L-shaped plate structure, which includes a horizontal plate and a vertical plate. The horizontal plate is connected to the upper end of the vertical plate. The horizontal plate is connected to the bogie by fasteners such as bolts. The vertical plate can be fitted to a certain vertical plane position of the bogie. In this embodiment, a connecting rod 120 is connected to each of the left and right sides of the hanger body 110, and the two connecting rods 120 are symmetrically arranged about the vertical center axis of the vertical plate. Taking one of the connecting rods 120 as an example, the connecting rod 120 includes a first rod body and a second rod body. The first rod body is connected to the second rod body, and the two are set at an obtuse angle. The end of the first rod body away from the second rod body is the first end of the connecting rod 120, which is arranged along the vertical direction and connected to the left edge of the hanger body 110. The end of the second rod away from the first rod is the second end of the connecting rod 120, which extends in a downward direction to the left side wall of the receiving box 200 at a position away from the hanger body 110 and is rotatably connected to the left side wall of the receiving box 200 through the pivot 700.

[0033] Therefore, when the receiving box 200 is pulled or pressed diagonally downwards, the receiving box 200 can flip to the side away from the hanger body 110, so that the anti-roller block 300 can be easily removed from the top opening of the receiving box 200 during use. After use, the receiving box 200 can also be flipped to the side away from the hanger body 110 first, and after the anti-roller block 300 is placed into the receiving box 200, the receiving box 200 can be released and will naturally flip to the side closer to the hanger body 110.

[0034] In one embodiment of the present invention, the wheel stop block assembly further includes a cover plate 400, which is rotatably connected to the hanger body 110 and is capable of being flipped to open or close the receiving box 200.

[0035] Furthermore, in one embodiment of the present invention, the anti-wheel block assembly further includes: a locking structure 500, which is disposed between the cover plate 400 and the receiving box 200. The locking structure 500 can switch between a locked position and an unlocked position. In the locked position, the cover plate 400 is locked to the receiving box 200, and in the unlocked position, the cover plate 400 is separated from the receiving box 200.

[0036] Specifically, such as Figure 1 and Figure 2 As shown, in this embodiment, one end of the cover plate 400 is connected via a hinge to the side of the vertical plate in the hanger body 110 away from the bogie. The cover plate 400 can be flipped relative to the receiving box 200 to close or open the top opening of the receiving box 200. A locking structure 500 is also provided between the cover plate 400 and the receiving box 200. For example, the locking structure 500 can be a latch lock. The latch lock includes a locked position and an unlocked position. When the wheel stop block 300 needs to be used, the latch lock is switched to the unlocked position so that the cover plate 400 can be separated from the receiving box 200, and the cover plate 400 is flipped to open the top opening of the receiving box 200. After use, the wheel stop block 300 is placed in the receiving box 200, the cover plate 400 is flipped to close the top opening of the receiving box 200, and then the latch lock is switched to the locked position to avoid the risk of the wheel stop block 300 falling off.

[0037] To facilitate the retrieval of the anti-roller block 300 inside the housing 200, a limiting structure can be provided between the cover plate 400 and the hanger body 110. When the cover plate 400 is flipped open, the limiting structure can limit the connection of the cover plate 400 so that the cover plate 400 can remain in the open state. For example, the limiting structure includes, but is not limited to, a magnetic limiting buckle.

[0038] In one embodiment of the present invention, the anti-wheel block assembly further includes an elastic member 600, which is connected to the inner side of the cover plate 400. In the locked position, the elastic member 600 can press against the anti-wheel block 300.

[0039] For example, such as Figure 2 As shown, in this embodiment, the elastic element 600 is an elastic pressure plate. The elastic pressure plate is disposed on the inner side of the cover plate 400. When the cover plate 400 is flipped to close the top opening of the receiving box 200 and the locking structure 500 is switched to the locked position, the elastic pressure plate can press against the wheel stop block 300. With this structural arrangement, on the one hand, the limiting reliability of the wheel stop block 300 can be improved; on the other hand, the wheel stop block 300 can be prevented from shaking during the operation of the rail vehicle, thereby effectively protecting the wheel stop block 300 and its corresponding fixing and receiving structure.

[0040] In one embodiment of the present invention, the anti-wheel block 300 includes: an anti-wheel block body 310, which can be placed inside the receiving box 200; and a handle, which is connected to the anti-wheel block body 310 and can be positioned to support the top opening of the receiving box 200.

[0041] Furthermore, in one embodiment of the present invention, the receiving box 200 includes: multiple side plates, each side plate being spliced ​​together to form a frame that fits around the wheel stop block body 310.

[0042] The wheel stop block body 310 can be placed inside the frame, and the handle can be limited and supported to the top opening of the frame.

[0043] For example, the receiving box 200 includes four side panels, which are joined together to form a square frame. The square frame is fitted to the wheel stop block body 310. When the wheel stop block body 310 is placed inside the square frame, the four side panels of the square frame are positioned as close as possible to the surrounding side walls of the wheel stop block body 310 to reduce its wobbling. A handle is provided on the wheel stop block body 310. When the wheel stop block body 310 is placed inside the square frame, the handle can be positioned and supported up to the top opening of the square frame. Therefore, there is no need to provide a support plate at the bottom of the square frame, saving on the cost of the receiving box 200.

[0044] In another embodiment of the invention, the receiving box 200 further includes a base plate that can support the wheel stop block body 310.

[0045] In one embodiment of the present invention, a limiting groove is provided on the receiving box 200 near the opening of the cover plate 400, and the handle can be limited and supported in the limiting groove so that pressing the handle can cause the receiving box 200 to flip away from the hanger body 110, or releasing the handle can cause the receiving box 200 to flip towards the hanger body 110.

[0046] Further, in one embodiment of the present application, the handle includes: a first handle body 321 connected to one side of the stop block body 310, the first handle body 321 being parallel to the rotation shaft 700; and a second handle body 322 connected to the other side of the stop block body 310, the second handle body 322 being parallel to the rotation shaft 700.

[0047] The limiting groove includes: a first groove body 210 provided in the accommodating box 200, the first groove body 210 being adapted to the first handle body 321 so that the first handle body 321 is limited and supported in the first groove body 210; and a second groove body 220 provided in the accommodating box 200, the second groove body 220 being adapted to the second handle body 322 so that the second handle body 322 is limited and supported in the second groove body 220.

[0048] Specifically, as shown in Figure 1 and Figure 2 , the first handle body 321 and the second handle body 322 are symmetrically provided on the left and right side walls of the stop block body 310. For example, the first handle body 321 and the second handle body 322 are both cylindrical structures. The first handle body 321 and the second handle body 322 are both parallel to the rotation shaft 700. The first groove body 210 is provided on the left side plate of the accommodating box 200, and is a semicircular groove structure adapted to the first handle body 321. The second groove body 220 is provided on the right side plate of the accommodating box 200, and is a semicircular groove structure adapted to the second handle body 322. In the state that the stop block body 310 is placed in the accommodating box 200, the first handle body 321 can be limited and supported in the first groove body 210, and the second handle body 322 can be limited and supported in the second groove body 220. When the stop block body 310 needs to be taken out, the first handle body 321 and / or the second handle body 322 are pulled or pressed obliquely downward, and the accommodating box 200 can be driven to flip to the side away from the hanger body 110. After use, the stop block body 310 is placed in the accommodating box 200, and the first handle body 321 is supported in the first groove body 210 and the second handle body 322 is supported in the second groove body 220, then the first handle body 321 and the second handle body 322 are released, and the accommodating box 200 can naturally flip to the side close to the hanger body 110.

[0049] By symmetrically arranging the first and second cylindrical handle bodies on the left and right side walls of the wheel block body 310 and opening the corresponding semicircular grooves in the side plates of the accommodating box 200, the design achieves double optimization effects: in the storage state, the first handle body 321 and the second handle body 322 are accurately supported in the corresponding semicircular grooves, forming stable limiting support, effectively preventing the wheel block body 310 from shaking, shifting or accidentally coming out of the accommodating box 200 during the operation of the rail vehicle, significantly improving its storage reliability and safety; when taking, only need to pull or press any one or both handle bodies obliquely downward, the accommodating box 200 can be easily driven to overturn together with the wheel block 300 away from the hanging rack 100, greatly simplifying the operation steps, only by a single ergonomic action, the overturning and taking preparation can be quickly completed, further improving the convenience and efficiency of the operation. In addition, after placing the wheel block 300, only need to return the first handle body 321 and the second handle body 322 to the corresponding grooves and release, the accommodating box 200 can be automatically reset, realizing the simplification and automation of the storage process.
