[0046] The front opening and closing mechanism 5 includes a first mounting frame 51 and a second mounting frame 52, and the first mounting frame 51 and the second mounting frame 52 are both in a "C" shape. The first mounting frame 51 is mounted on the first mounting plate 3, and the second mounting frame 52 is mounted on the second mounting plate 4. The "C"-shaped openings of the first mounting frame 51 and the second mounting frame 52 are arranged opposite to each other. The first mounting frame 51 and the second mounting frame 52 are rotatably connected at one end close to each other.

[0047] Two first bolts 31 are provided on the first mounting plate 3 and the second mounting plate 4. The two first bolts 31 are arranged up and down. The first bolt 31 on the first mounting plate 3 passes through the first mounting plate 3 and is threadedly connected to the first mounting plate 3. The first mounting frame 51 is provided with a first plugging hole 511 for the first bolt 31 to be plugged in.

[0048] A second socket (not shown in the figure) is provided on the side of the second mounting frame 52 close to the second mounting plate 4, the first bolt 31 on the second mounting plate 4 passes through the second mounting plate 4 and is threadedly connected to the second mounting plate 4, and the first bolt 31 on the second mounting plate 4 is plugged into the second socket on the second mounting frame 52.

[0049] Abutment blocks 32 are fixed on the sides of the first mounting plate 3 and the second mounting plate 4 that are close to each other, and a clamping assembly 6 is provided on the first mounting plate 3 and the second mounting plate 4. The first mounting frame 51 is located between the abutment block 32 and the clamping assembly 6 on the first mounting plate 3, and the second mounting frame 52 is located between the abutment block 32 and the clamping assembly 6 on the second mounting plate 4.

[0050] When assembling the front opening and closing mechanism 5, first place one side of the first mounting frame 51 between the abutting block 32 on the first mounting plate 3 and the abutting assembly 6, and insert the first bolt 31 into the first insertion hole 511 on the first mounting frame 51, so that the first bolt 31 supports the first mounting frame 51. After the first bolt 31 is inserted into the first insertion hole 511, one side of the first mounting frame 51 contacts the abutting block 32.

[0051] Then, one side of the second mounting frame 52 is placed between the abutting block 32 on the second mounting plate 4 and the abutting assembly 6 , and the first bolt 31 on the second mounting plate 4 is plugged into the second plug hole on the second mounting frame 52 .

[0052] The following description will take the abutting assembly 6 on the first mounting plate 3 as an example to explain the abutting assembly 6. Figure 1 , Figure 4 and Figure 5 The clamping assembly 6 includes a first clamping plate 61 and a fixed plate 62. The fixed plate 62 is fixed to the first mounting plate 3. The first clamping plate 61 is located on the side of the fixed plate 62 close to the abutment block 32. A first connecting rod 63 is fixed to the side of the first clamping plate 61 close to the fixed plate 62. An end of the first connecting rod 63 away from the first clamping plate 61 passes through the fixed plate 62 and is fixed with a first pull block 631.

[0053] A first spring 64 is disposed between the fixing plate 62 and the first abutting plate 61 . One end of the first spring 64 is fixed to the first abutting plate 61 , and the other end of the first spring 64 is fixed to the fixing plate 62 . The first spring 64 is sleeved with the first connecting rod 63 .

[0054] The first abutting plate 61 abuts against the side wall of the first mounting frame 51, and under the action of the first spring 64, the first abutting plate 61 abuts against the first mounting frame 51. A draw hook 33 is provided above the fixing plate 62, and one end of the draw hook 33 is hinged to the first mounting plate 3. When the first mounting frame 51 is to be disassembled, the first pull block 631 is first pulled to separate the first abutting plate 61 from the first mounting frame 51, and the first abutting plate 61 presses against the first spring 64, and the draw hook 33 is rotated to make the hook-shaped end of the draw hook 33 hook the first abutting plate 61. The first abutting plate 61 is separated from the first mounting frame 51, so that the first mounting frame 51 can be easily disassembled.

[0055] Reference Figure 1 , Figure 2 and Figure 3 A connecting plate 53 is connected to one side of the first mounting frame 51 close to the vertical support plate 1. The connecting plate 53 includes a first connecting plate 531 and a second connecting plate 532. The first connecting plate 531 is arranged in a horizontal direction, and the second connecting plate 532 is arranged in a vertical direction. The first connecting plate 531 and the second connecting plate 532 are arranged vertically and fixed. The second connecting plate 532 is located on one side of the first connecting plate 531 close to the vertical support plate 1.

[0056] A support block 11 is fixed to one side of the vertical support plate 1 close to the second connecting plate 532. The support block 11 is located below the second connecting plate 532, and the support block 11 supports the second connecting plate 532. Limiting plates 12 are fixed to both sides of the vertical support plate 1. The two limiting plates 12 are located on both sides of the support block 11, respectively. The height of the limiting plates 12 is higher than the support block 11. The second connecting plate 532 is located between the two limiting plates 12, and limits the second connecting plate 532.

[0057] The second connecting plate 532 is provided with a second bolt 13 , which passes through the second connecting plate 532 and is threadedly connected to the vertical supporting plate 1 , thereby increasing the stability of the second connecting plate 532 and the first connecting plate 531 , thereby increasing the stability of the first mounting frame 51 .

[0058] When installing the first mounting frame 51, place the second connecting plate 532 on the supporting block 11, and pass the second bolt 13 through the second connecting plate 532 and threadedly connect it to the vertical supporting plate 1. After the first mounting frame 51 and the second mounting frame 52 are installed, the remaining parts of the front opening and closing mechanism 5 are assembled. By setting the assembly support frame of the front opening and closing mechanism of the coupler deflector, the first mounting frame 51 and the second mounting frame 52 are placed on the device first, and then the remaining parts are assembled.

[0059] It is convenient to assemble the front opening and closing mechanism, thus improving the assembly efficiency.

[0060] Reference Figure 6 A plug plate 151 is fixed to the side of the second mounting plate 4 close to the second horizontal support plate 15, and a slot 152 is provided on the side of the second horizontal support plate 15 close to the second mounting plate 4, and the plug plate 151 is plugged into and matched with the slot 152. A cylinder 153 is fixed to the side of the second horizontal support plate 15 away from the second mounting frame 52, and a moving plate 41 is fixed to the side wall of the second mounting plate 4, and the piston rod of the cylinder 153 is fixed to the moving plate 41. The cylinder 153 can drive the moving plate 41 and the second mounting plate 4 to approach or move away from the second horizontal support plate 15.

[0061] When disassembling the front opening and closing mechanism 5, first separate the corresponding first abutting plates 61 on the first mounting plate 3 and the second mounting plate 4 from the first mounting frame 51 and the second mounting frame 52 respectively. Start the cylinder 153, which pushes the moving plate 41 and the second mounting plate 4 to move away from the first mounting plate 3, and the first bolt 31 on the second mounting plate 4 is pulled out from the second plug hole on the second mounting frame 52. Then unscrew the second bolt 13, and remove the assembled front opening and closing mechanism 5 from the assembly support frame. When the piston rod of the cylinder 153 is extended to the longest, the end of the plug plate 151 away from the second mounting plate 4 is still located in the slot 152.

[0062] A rubber stopper is fixed between the first mounting plate 3 and the first mounting frame 51, and a rubber stopper is also fixed between the second mounting plate 4 and the second mounting frame 52 (the rubber stopper is not shown in the figure). The first bolt 31 passes through the rubber stopper. The rubber stopper can reduce the paint wear on the side of the first mounting frame 51 close to the first mounting plate 3, and reduce the paint wear on the side of the second mounting frame 52 close to the second mounting plate 4.

[0063] The implementation principle of an assembly support frame of an opening and closing mechanism at the front end of a coupler air deflector in an embodiment of the present application is as follows: when installing the front end opening and closing mechanism 5, first install the first mounting frame 51 so that the first mounting frame 51 is placed between the abutment block 32 on the first mounting plate 3 and the first clamping plate 61, the first bolt 31 is inserted into the first plug hole 511 on the first mounting frame 51, the second bolt 13 passes through the second connecting plate 532 and is threadedly connected to the vertical support plate 1, and the first clamping plate 61 is clamped against the first mounting frame 51 under the action of the first spring 64.

[0064] Then, the second mounting frame 52 is installed, and one side of the second mounting frame 52 is placed between the abutment block 32 on the second mounting plate 4 and the first clamping plate 61 , so that the first bolt 31 on the second mounting plate 4 is inserted into the second insertion hole, and the first clamping plate 61 is pressed against the second mounting frame 52 .

[0065] Then assemble the first mounting frame 51 and the second mounting frame 52 and assemble the remaining parts. After the front-end opening and closing mechanism 5 is assembled, first pull the first pull block 631 to move the first clamping plate 61 on the first mounting plate 3 away from the first mounting frame 51, and rotate the hook 33 to hook the first clamping plate 61. Similarly, make the hook 33 on the second mounting plate 4 hook the first clamping plate 61, then start the cylinder 153, and the cylinder 153 drives the second mounting plate 4 to move away from the first mounting plate 3, and then unscrew the second bolt 13, move the assembled front-end opening and closing mechanism 5 a short distance away from the first mounting plate 3, so that the first bolt 31 on the first mounting plate 3 is disengaged from the first socket 511, and the assembled front-end opening and closing mechanism 5 is removed from the support frame.
