As shown in fig. 1, the ballast car is provided with funnels 2, in which two funnels 2 are provided, and the two funnels 2 are arranged at intervals in the longitudinal direction of the car. A manual opening and closing mechanism 4 and an automatic opening and closing mechanism (not shown in the figure) are further arranged, a bottom door 1 is arranged at the bottom discharge opening of the funnel 2, and the bottom door 1 is rotatably connected to the side wall of the funnel 2. The manual opening and closing mechanism 4 is arranged at the bottom of the frame 5 of the ballast car, and can open and close the bottom door 1 of the car by manpower. The automatic opening and closing mechanism is well known to those skilled in the art and the structure thereof is not described herein. When the bottom door 1 is opened, stone ballast can be discharged through the bottom discharge opening of the hopper 2.
The manual opening and closing mechanism 4 is arranged at the bottom of the frame 5, so that an operator can operate the manual opening and closing mechanism 4 by standing on the ground without standing on the vehicle, the operation is more convenient, and the opening condition of the bottom door 1 can be observed in the operation process.
As shown in fig. 2, two bottom doors 1 are provided at the bottom of each funnel 2, and the two bottom doors 1 are provided at intervals in the transverse direction of the vehicle, and four bottom doors 1 are provided in total. The bottom doors 1 are side-by-side doors, and each bottom door 1 has two side-by-side sections 11. The opposite longitudinal ends of the split 11 are rotatably connected to the side walls of the hopper 2, and the split 11 is opened and closed by rotation about the longitudinal direction of the vehicle.
As shown in fig. 5, the split 11 is rotatably connected to the side wall of the funnel 2 by the following structure: the split part 11 is provided with a first pin hole 111, the side wall of the funnel 2 is provided with a second pin hole, and the pin shaft 3 is inserted into the first pin hole 111 and the second pin hole, so that the split part 11 can rotate relative to the funnel 2 by taking the axis of the pin shaft 3 as a rotation center line. Of course, in practical implementation, the split 11 and the side wall of the funnel 2 may be connected by a rotatable connection such as hinging, riveting, etc.
As shown in fig. 3, the manual opening and closing mechanism 4 includes a transmission shaft 41, a clutch, a worm gear assembly, a transmission shaft bearing block 46, a worm bearing block 47, a shift fork 48, a hand wheel 45, and the like.
The transmission shaft 41 is inserted into the bearing inner hole of the transmission shaft bearing seat 46 in an adaptive manner, and the transmission shaft 41 is connected with the split part 11 of the bottom door 1 in a transmission way through a clutch. The drive shaft bearing housing 46 is mounted to the bottom of the frame 5 by a top mounting plate.
The worm and gear assembly includes a worm 44 and a worm wheel 43 that intermesh. The worm 44 is fittingly inserted into a bearing bore of a worm bearing housing 47, the worm bearing housing 47 being mounted at the bottom of the frame 5 by means of a top mounting plate. The worm wheel 43 is synchronously rotatably sleeved on the transmission shaft 41, and the hand wheel 45 is synchronously rotatably sleeved on the worm 44. It should be noted that, in order to allow the two members to be mounted together in a synchronous rotation manner, the relative positions of the two members in the rotation direction (i.e., in the circumferential direction) need to be fixed.
As shown in fig. 4, the clutch includes two clutch portions, a first clutch portion 421 and a second clutch portion 422. The first clutch portion 421 is synchronously rotatably mounted on the transmission shaft 41, and the second clutch portion 422 is synchronously rotatably mounted on the split portion 11 of the bottom door 1. The first clutch portion 421 and/or the second clutch portion 422 are slidable in the axial direction of the drive shaft 41, and thus can be slid to a position where they are engaged with each other or a position where they are disengaged from each other, so that they can be engaged with each other or disengaged from each other.
In the figure, the first clutch portion 421 can slide along the axial direction of the transmission shaft 41, and a fork opening is formed in the outer periphery of the first clutch portion 421, and one end of the fork 48 extends into the fork opening, so that the first clutch portion 421 can be shifted to slide axially by the fork 48, which is more labor-saving than directly shifting the first clutch portion 421 to slide axially. The first clutch 421 can slide axially, which is convenient for operation.
In the drawing, the second clutch part 422 is fixedly connected to the split part 11 of the bottom door 1, and therefore cannot slide in the axial direction of the drive shaft 41. As shown in fig. 5, the second clutch portion 422 is specifically fixed at the distal end opening of the first pin hole 111 of the split portion 11 away from the side wall of the funnel 2, and seals the distal end opening of the first pin hole 111, so that the second clutch portion 422 and the split portion 11 are fixedly connected, and the pin shaft 3 can be prevented from falling out of the distal end opening of the first pin hole 111.
When the bottom door 1 is opened and closed by adopting the automatic opening and closing mechanism, the first clutch part 421 and the second clutch part 422 of the clutch are separated, so that the manual opening and closing mechanism 4 can be prevented from influencing the use of the automatic opening and closing mechanism.
When the bottom door 1 is opened and closed by the manual opening and closing mechanism 4, the first clutch portion 421 is manually moved by the fork 48, so that the first clutch portion 421 and the second clutch portion 422 are engaged. Then, the hand wheel 45 is driven by manpower to rotate forward, the worm 44 is driven by the hand wheel 45 to rotate so as to drive the worm wheel 43 to rotate so as to drive the transmission shaft 41 to rotate, and finally the split part 11 of the bottom door 1 is driven by the engaged clutch to rotate by taking the axis of the pin shaft 3 as a rotation center line, so that the split part 11 is opened, otherwise, the split part 11 can be closed by the hand wheel 45 which is driven by manpower to rotate reversely.
The manual opening and closing mechanism 4 does not use hydraulic pressure, air pressure and electric components at all, so the reliability is relatively high; moreover, the manual opening and closing mechanism 4 has a simple and compact overall structure and occupies small arrangement space; moreover, the manual opening and closing mechanism 4 adopts the worm and gear assembly for transmission, so that the transmission ratio is large, the operation is labor-saving, and the manual opening and closing mechanism has a self-locking function, and can lock the split part 11 at a target position, thereby realizing the opening degree maintenance on the basis of not additionally arranging a positioning component; moreover, the manual opening and closing mechanism 4 is arranged at the bottom of the frame 5, so that an operator can operate the manual opening and closing mechanism 4 by standing on the ground, the operation is more convenient, and the opening condition of the bottom door 1 can be observed in the operation process.
Specifically, referring to fig. 2 and 3, the manual opening and closing mechanism 4 includes a plurality of transmission shafts 41, and the number of the transmission shafts 41 is the same as the number of the corresponding groups of the side-by-side doors of the hopper 2. In the figure, eight split portions 11 are provided in total, and two split portions 11 adjacent to each other in the vehicle longitudinal direction are provided as one split group 11a, so four split groups 11a are provided in total, and therefore four propeller shafts 41 are provided in total. In practical implementation, the number of split groups 11a is not limited to four, and if the number of split groups 11a is changed, the number of transmission shafts 41 needs to be changed.
As shown in fig. 2 and 3, a first clutch portion 421 is respectively installed at two ends of each transmission shaft 41, a second clutch portion 422 is respectively installed on each split portion 11, and the first clutch portions 421 and the second clutch portions 422 are in one-to-one correspondence. By this arrangement, each of the split portions 11 of the vehicle can be opened and closed individually, so that the effect of discharging at different positions can be achieved.
In the figure, all transmission shafts 41 of the manual opening and closing mechanism 4 are parallel to each other, and two first clutch parts 421 on each transmission shaft 41 are respectively matched with two second clutch parts 422 on a group of opposite opening parts 11. The arrangement can be convenient for arrangement, and arrangement space is saved more easily.
With continued reference to fig. 2 and 3, the worm gear assembly includes two worm gear units, each of which is comprised of a worm 44 and two worm gears 43 that engage the worm 44. In the figure, four transmission shafts 41 of the manual opening and closing mechanism 4 are divided into two groups, one group is divided into two groups on one side and the other group is divided into two groups on the other side along the transverse direction of the vehicle, and the two groups are respectively driven to rotate by the two worm gear units, so that the two worms 44 are arranged without being too long, and the strength is relatively easy to ensure. In the figure, the outer ends of the two worms 44 are respectively sleeved with a hand wheel 45 so as to respectively operate and rotate the two worms 44 on two sides of the vehicle.
Of course, in practical implementation, the four transmission shafts 41 may be driven by the same worm gear unit, and in this case, the number of worm gears 43 of the worm gear unit is four, that is, four worm gears 43 are simultaneously meshed with one worm 44.
