Fig. 1 is a schematic structural view of a hopper car bottom door opening and closing mechanism according to the present invention;
FIG. 2 is a top view of the hopper car bottom door opening and closing mechanism of the present invention;
wherein: 1. a circular arc-shaped side wall; 2. a funnel spine; 3. a chassis; 4. a left door; 5. a right door; 6. a door hinge base; 7. a drive shaft; 8. double crank; 9. a left connecting rod; 10. a right connecting rod; 11. the transmission shaft supports.
Detailed Description
The technical solution of the present invention will be further explained with reference to the accompanying drawings and specific embodiments.
A hopper wagon bottom door opening and closing mechanism comprises a circular arc-shaped side wall 1, a hopper ridge 2, an underframe 3, a bottom door which is matched with the bottom door and covers between the side wall 1 and the hopper ridge 2, wherein the bottom door comprises a left door 4 and a right door 5 which are installed on the underframe 3 through a door folding seat 6, and the bottom door opening and closing mechanism further comprises a transmission shaft 7, a double crank 8, a left connecting rod 9 and a right connecting rod 10, and is shown in figure 1.
The transmission shaft 7 is rotatably mounted on the base frame 3 around its own axis, and here, a transmission shaft bracket 11 is further mounted on the base frame 3, and as shown in fig. 1, the transmission shaft 7 is rotatably mounted on the transmission shaft bracket 11 along its own axis. In this example, the drive shaft 7 is mounted below the chassis 3 at a position near the middle of the chassis 3.
Here, the double crank 8 is connected to the transmission shaft 7 through a key (not shown in the figure) and rotates along with the rotation of the transmission shaft 7, two ends of the double crank 8 are respectively connected with the left connecting rod 9 and the right connecting rod 10 in a rotating manner, specifically, one end of the left connecting rod 9 is connected with one end of the double crank 8 in a rotating manner through a pin shaft (not shown in the figure), and the other end is connected with the left door 4 in a rotating manner; one end of the right connecting rod 10 is rotationally connected with the other end of the double crank 8 through a pin shaft, and the other end is rotationally connected with the right door 5.
Here, the left door 4, the left link 9, the double crank 8, and the transmission shaft 7 constitute a four-link mechanism, and the right door 5, the right link 10, the double crank 8, and the transmission shaft 7 also constitute a four-link mechanism. When the bottom door needs to be opened, the transmission shaft 7 is driven to rotate anticlockwise to drive the double cranks 8 to rotate anticlockwise, and further the left connecting rod 9 and the right connecting rod 10 are driven to move towards the middle of the bottom frame 3, so that the left door 4 and the right door 5 respectively rotate around the corresponding door folding seats 6, the left door 4 rotates clockwise, the right door 5 rotates anticlockwise, and the left door 4 and the right door 5 are gradually opened; when the bottom door needs to be closed, the transmission shaft 7 is driven to rotate clockwise. Through this mode of setting up, at the discharge in-process, the material in the left and right sides funnel shunts from funnel back both sides, and the centre is unloaded, has improved discharge efficiency greatly.
In this example, there are two sets of bottom doors, as shown in fig. 2, distributed along the length direction of the chassis 3, each set of bottom doors corresponds to a set of bottom door opening and closing mechanisms, and the two sets of bottom door opening and closing mechanisms share one transmission shaft 7, so that when the transmission shaft 7 rotates, the two sets of bottom doors are both opened or closed at the same time, thereby greatly improving the unloading efficiency.
In this example, each set of bottom door opening and closing mechanism at least comprises two double cranks 8, two left connecting rods 9, two right connecting rods 10 and two transmission shaft brackets 11. Through this mode of setting up, play a fine supporting role to the bottom door.
