[0036] like Figure 1-4 A rail hook device for a rail transport vehicle comprises: a rail hanger bracket 1, a rail hook 2, and a locking pin 3.

[0037] There are two rail hooks 2 , which are rotatably connected to the hanging rail bracket 1 , and both rail hooks 2 are provided with fixing holes 21 .

[0038] The locking pin 3 can pass through the fixing holes 21 of the two rail hooks 2 in sequence so that the two rail hooks 2 are relatively fixed.

[0039] In this embodiment, after the rail transport vehicle rail hook device is moved to the rail head, the rail hook 2 is unfolded and placed on the rail head. At this time, the rail hook 2 is released and the rail hook 2 will automatically close under the action of gravity. Then the locking pin 3 is inserted into the fixing hole 21 of the rail hook 2 to lock the relative positions of the two rail hooks 2.

[0040] The rail hook 2 is provided with a fixing hole 21 for inserting the locking pin 3, thereby fixing the opening and closing of the rail hook 2, thereby improving safety.

[0041] like Figure 4 As shown, based on the above embodiment, it also includes a connecting member, which is a flexible member, one end of which is connected to the hanging rail bracket 1 or the rail hook 2, and the other end of the connecting member is connected to the locking pin 3.

[0042] Specifically, the connecting piece may be a metal chain or a rope.

[0043] In this embodiment, one end of the connecting member is connected to the hanging rail bracket 1 or the rail hook 2, and the other end of the connecting member is connected to the locking pin 3, so that the locking pin 3 is flexibly connected to the hanging rail bracket 1 or the rail hook 2, thereby preventing the locking pin 3 from falling and being lost.

[0044] like Figure 4 As shown, on the basis of the above embodiment, the hanging rail bracket 1 or the rail hook 2 is provided with a connecting hole 22, and one end of the connecting member is connected to the hanging rail bracket 1 or the rail hook 2 through the connecting hole 22.

[0045] In this embodiment, the connecting hole 22 is provided on the rail hook 2, and the connecting hole 22 is used to connect the connecting member.

[0046] like Figure 1-Figure 2 As shown, on the basis of the above embodiment, the hanging rail bracket 1 or the rail hook 2 is provided with a receiving hole 11, and the locking pin 3 can be inserted into the receiving hole 11.

[0047] In this embodiment, the receiving hole 11 is arranged on the hanging rail bracket 1. When the rail hook 2 clamps the rail head, the locking pin 3 is taken out of the receiving hole 11 and inserted into the fixing hole 21 of the rail hook 2 to ensure the safety and stability of the rail hook device of the rail transport vehicle.

[0048] After the rail hook device for the rail transport vehicle is used, the locking pin 3 is pulled out from the fixing hole 21 and inserted into the receiving hole 11 for next use.

[0049] Preferably, the bottom of the receiving hole may be provided with an internal thread, and the end of the locking pin may be provided with an external thread, and the locking pin may be fixed to the receiving hole by a threaded connection.

[0050] like Figure 3 As shown, on the basis of the above embodiment, it also includes a limit pin (not shown in the figure), one end of the locking pin 3 is provided with a first positioning portion 31, the diameter of the first positioning portion 31 is larger than the fixing hole 21, and the other end of the locking pin 3 is provided with a limit hole 32, and the limit pin can pass through the limit hole 32.

[0051] In this embodiment, when the locking pin 3 passes through the fixing hole 21 on the rail hook 2, because the diameter of the first positioning portion 31 at one end thereof is larger than the fixing hole 21, the first positioning portion 31 contacts the end surface of the fixing hole 21, so that the locking pin 3 cannot continue to pass through. At this time, the position of the locking pin 3 can be locked by inserting the limit pin into the limit hole 32 at the other end of the locking pin 3.

[0052] like Figure 3As shown, based on the above embodiment, it also includes a connecting member (not shown in the figure), which is a flexible member, one end of which is connected to the hanging rail bracket 1 or the rail hook 2, and the other end of the connecting member is connected to the first positioning portion 31.

[0053] In this embodiment, one end of the connecting member is connected to the first positioning portion 31 of the locking pin 3 , and this connection method will not affect the normal use of the locking pin 3 .

[0054] like Figure 1 As shown, on the basis of the above embodiment, the rail hook 2 is provided with a first limiting portion 23, and the other rail hook 2 is provided with a second limiting portion 24, and the first limiting portion 23 can contact the second limiting portion 24 to limit the minimum angle of the two rail hooks 2.

[0055] In this embodiment, due to the gravity of the rail hook 2 itself, the ends of the two rail hooks 2 away from the rail hook bracket 1 will move closer to each other, thereby driving the first limiting portion 23 and the second limiting portion 24 to move closer to each other. When the first limiting portion 23 contacts the second limiting portion 24, the two rail hooks 2 stop rotating closer.

[0056] like Figure 1-Figure 4 As shown, on the basis of the above embodiment, it also includes a rotating pin 4, the hanging rail bracket 1 is provided with a first rotating hole 12, and the rail hook 2 is provided with a second rotating hole 25, and the rotating pin 4 can pass through the first rotating hole 12 and the second rotating holes 25 of the two rail hooks 2 so that the rail hook 2 can be rotatably connected to the hanging rail bracket.

[0057] In this embodiment, the first rotating hole 12 of the hanging rail bracket 1 is concentric with the second rotating hole 25 on the two rail hooks 2. At this time, the rotating pin 4 passes through the first rotating hole 12 of the hanging rail bracket 1 and the second rotating hole 25 of the two rail hooks 2, so that the two rail hooks 2 are rotatably connected to the hanging rail bracket 1 through the rotating pin 4.

[0058] like Figure 3 As shown, on the basis of the above embodiment, it also includes a limit ring 42, a second positioning portion 41 is provided at one end of the rotating pin 4, the diameter of the second positioning portion 41 is larger than the first rotating hole 12, and the limit ring 42 is detachably connected to the other end of the rotating pin 4.

[0059] In this embodiment, when the rotating pin 4 passes through the first rotating hole 12 of the hanging rail bracket 1 and the second rotating holes 25 of the two rail hooks 2, because the diameter of the second positioning portion 41 at one end thereof is larger than the rotating hole 12, the second positioning portion 41 contacts the end surface of the first rotating hole 12, making it impossible for the rotating pin 4 to continue passing through. Then, the limit ring 42 is assembled at the other end of the rotating pin 4 to fix the position of the rotating pin 4 so that it will not slip out easily.

[0060] Secondly, a rail transport vehicle is also proposed, comprising the above-mentioned rail transport vehicle rail hook device.
