Example

[0029] Figure 1 FIG. 1 is a schematic diagram of the door opening structure of the ore hopper car provided in this embodiment. Figure 1 As shown, the ore hopper car includes a car body, a left half bin 1 and a right half bin 2, the left half bin 1 and the right half bin 2 are rotatably connected to the car body, the left half bin 1 and the right half bin 2 are provided with connecting rod mechanisms on both sides, the car body is connected with a driving mechanism, the output end of the driving mechanism is connected to the connecting rod mechanism, the driving mechanism is used to drive the connecting rod mechanism to drive the left half bin 1 and the right half bin 2 to rotate relative to each other around their respective connections with the car body to realize opening and closing of the bin, and also includes:

[0030] A limiting mechanism is arranged on the vehicle body, and is used to limit one of the half bins when the left half bin 1 and the right half bin 2 are closed, so that the closing speed of the half bin body is slower than that of the other half bin, and then an overlap is formed at the junction of the left half bin 1 and the right half bin 2 after closing;

[0031] The limiting mechanism comprises:

[0032] A limit rod 10 is rotatably connected to the vehicle body, the limit rod 10 is tilted to the right, and a limit block 15 is provided below the connection between the limit rod 10 and the vehicle body;

[0033] A support rod 11 is arranged on the inner side wall of the left half compartment 1 close to the center line of the vehicle body, and the support rod 11 extends out of the left half compartment 1;

[0034] A stopper 9 is provided on the inner side wall of the right half compartment 2 near the center line of the vehicle body;

[0035] The support rod 11, the limiting rod 10 and the stopper 9 are arranged on the same side, and the end of the limiting rod 10 away from the connection with the vehicle body is on the movement trajectory of the support rod 11 and the stopper 9 when the left half warehouse 1 and the right half warehouse 2 rotate around their respective connections with the vehicle body to close the warehouse.

[0036] By eliminating the chassis part in the traditional structure, the loading is directly carried out in the cavity 8 between the left half warehouse 1 and the right half warehouse 2, which simplifies the structure and reduces the deadweight of the vehicle body. The driving mechanism drives the connecting rod mechanism to drive the left half warehouse 1 and the right half warehouse 2 to rotate relative to each other around their respective connections with the vehicle body to achieve opening and closing. In the process of closing the warehouse, the limiting mechanism can make the closing speed of the right half warehouse 2 slower than that of the left half warehouse 1, so that an overlap is formed between the left half warehouse 1 and the right half warehouse 2 after closing, thereby reducing the possibility of affecting the sealing after closing when the right end surface of the left half warehouse 1 and the left end surface of the right half warehouse 2 are deformed;

[0037] When the right half warehouse 2 rotates to the left around the connection point with the vehicle body, the stopper 9 on the right half warehouse 2 moves synchronously with the right half warehouse 2 to contact the limit rod 10. The limit rod 10 gives a certain friction force to the stopper 9, causing the right half warehouse 2 to pause, while the left half warehouse 1 will continue to rotate to the right under the action of inertia, thereby making the closing speed of the left half warehouse 1 faster than that of the right half warehouse 2, so that the left half warehouse 1 reaches the closing position first, and the right half warehouse 2 arrives at the closing position later, so that the bottom of the left end of the right half warehouse 2 is at the left half warehouse 1, so that the left half warehouse 1 and the right half warehouse 2 are overlapped; a limit block 15 is arranged below the connection between the limit rod 10 and the vehicle body to ensure that the limit rod 10 is always tilted to the right; the support rod 11 on the left half warehouse 1 can push the limit rod 10 when it contacts the limit rod 10, reducing its friction force on the block 9, and then reducing the obstruction of the limit rod 10 to the block 9 after the closing speed difference between the left half warehouse 1 and the right half warehouse 2 is formed, so that the subsequent closing action of the right half warehouse 2 can be carried out normally.

[0038] In this embodiment, the connecting rod mechanism includes:

[0039] A crank rod 3 is rotatably connected to the front and rear sides of the left half-bin 1. A short lever 4 is hinged at one end of the crank rod 3 away from the left half-bin 1. A rotating shaft 5 is connected between the side of the short lever 4 away from the crank rod 3. The rotating shaft 5 passes through the front and rear sides of the right half-bin 2 and is rotatably connected to the right half-bin 2.

[0040] The driving mechanism is an opening and closing cylinder 6 ; the opening and closing cylinder 6 is connected to the vehicle body, and an output end thereof is connected to a pendulum block 7 , and the pendulum block 7 is connected to a short lever 4 .

[0041] The air intake at the lower air inlet of the opening and closing cylinder 6 causes the cylinder rod to retract. During the cylinder retraction process, it pulls the short lever 4 to rotate rightward, and the short lever 4 pulls the bent rod 3 to rotate rightward. Under the action of the rotating shaft 5, the short rods and bent rod 3 before and after the left half warehouse 1 and the right half warehouse 2 all rotate rightward, thereby driving the left half warehouse 1 to rotate counterclockwise to the right around the connection between it and the vehicle body, and the right half warehouse 2 to rotate clockwise to the left around the connection between it and the vehicle body, thereby forming a closing action; and during the closing process, the limiting mechanism makes the closing speed of the right half warehouse 2 lower than the closing speed of the left half warehouse 1, thereby forming an overlap between the left half warehouse 1 and the right half warehouse 2 when closing, thereby reducing the possibility of deformation of the right end surface of the left half warehouse 1 and the left end surface of the right half warehouse 2 affecting the sealing after closing the door.

[0042] In this embodiment, the connecting line between the center points of the left end and the right end of the short lever 4 is not in a horizontal position.

[0043] In this way, self-locking can be achieved when the short lever 4 drives the curved rod 3 to bypass the dead point position.

[0044] In this embodiment, the left half bin 1 and the right half bin 2 both include a bottom door plate 12 , and vertical end plates 13 are provided on the front and rear sides of the bottom door plate 12 , and a cavity 8 is formed between the end plates 13 and the bottom door plate 12 .

[0045] A cavity 8 for containing the load can be directly formed between the end plate 13 and the bottom door plate 12, thereby simplifying the structure and reducing the deadweight of the vehicle body.

[0046] In this embodiment, a cavity is defined in the bottom door plate 12 , a press-formed component 14 is disposed in the cavity, and the press-formed component 14 is connected to the upper and lower side walls of the cavity.

[0047] The bottom door plate 12 is provided with a cavity to reduce the weight of the bottom door plate 12 , and the press-formed member 14 connected to the upper and lower side walls of the cavity can improve the strength of the bottom door plate 12 .

[0048] In this embodiment, the bottom door is made of NM400 material.

[0049] The bottom door is made of NM400 material, which is high in strength and wear-resistant, thus increasing the service life of the equipment.

[0050] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
