Embodiment 1

[0050] See attached image 3 , in order to more clearly show the technical solution and action process of the bottom door clearance adjustment mechanism provided by the first embodiment of the present invention provided by the present invention, the appended image 3 Only the case of one bottom gate is given.

[0051] Each bottom door has a first side bottom door 5 and a second side bottom door 31 respectively. The first side bottom door 5 and the second side bottom door 31 are opened by standing up to both sides. The bottom door 5 on the first side and the bottom door 31 on the second side are closed to each other. One of them), the link type transmission mechanism, the link type transmission mechanism includes a first connecting rod 2, a second connecting rod 9 and a plurality of third connecting rods, between the first connecting rod 2 and the second connecting rod 9 hinged. The free end 33 of the telescopic original moving part (in this embodiment, the telescopic origin...

Embodiment 2

[0069] See attached Figure 5 And attached Figure 6 , the hopper car provided by the present invention has the bottom door gap adjustment mechanism provided by the present invention, and when there is only one telescopic original moving part (in this embodiment, the telescopic original moving part is selected from one of an air cylinder, a hydraulic cylinder, and a jack) ), the opening or closing of multiple bottom doors can be simultaneously controlled through the link-type transmission mechanism, and the control system is simple;

[0070] Moreover, it can also achieve the purpose of adjusting the gap between the bottom doors on both sides of each bottom door.

[0071] In order to further explain the technical means and effects that the present invention takes to achieve the intended purpose of the invention, the specific implementation, structure, characteristics and features of the bottom door clearance adjustment mechanism proposed according to the present invention will...

Embodiment 3

[0074] See attached Figure 7 , improve on the basis of the bottom door gap adjustment mechanism provided in Embodiment 1 of the present invention, the bottom door gap adjustment mechanism provided in Embodiment 3 of the present invention also includes a fourth connecting rod 4, and the first connecting rod 2 passes through the fourth connecting rod 4 is hinged with the second connecting rod 9, and the hinge point between the first connecting rod 2 and the fourth connecting rod 4 is 71. At this time, the structure composed of the first connecting rod 2 and the fourth connecting rod 4 is similar to the human arm , and the hinge point 35 is similar to a human hand, so that it is more convenient to transmit the action force.

Abstract

The invention discloses a bottom door clearance adjustment mechanism and a hopper car and belongs to the technical field of hopper cars for railways. The bottom door clearance adjustment mechanism comprises a telescopic type driving component and a connecting rod type drive mechanism, wherein the connecting rod type drive mechanism comprises a first connecting rod, a second connecting rod and a plurality of telescopic type third connecting rods, the first connecting rod and the second connecting rod are hinged, a free end of the telescopic driving component is hinged to the free end of the first connecting rod, and the second connecting rod is hinged with a first side bottom door and a second side bottom door of each bottom door through the telescopic type third connecting rods respectively. The hopper car is provided with the bottom door clearance adjustment mechanism. According to the bottom door clearance adjustment mechanism and the hopper car, a plurality of bottom doors are controlled to be opened or closed simultaneously by the connecting rod type drive mechanism on the basis of only one telescopic type driving component, and the control system is simple; clearance adjustment of two side bottom doors of each bottom door can be achieved.

Description

technical field [0001] The invention relates to the technical field of railway hopper cars, in particular to a bottom door gap adjustment mechanism and a hopper car. Background technique [0002] The hopper car is a bottom unloading vehicle, which is mainly used to transport bulk cargo. After the vehicle arrives at the destination, the bottom door at the bottom of the compartment is opened, and the bulk cargo is unloaded by the gravity of the cargo itself. There is a hopper car in the prior art, each bottom door has a first side bottom door and a second side bottom door respectively, and the first side bottom door and the second side bottom door can be opened by standing up to both sides, and the opening and closing The reverse action makes the first side bottom door and the second side bottom door close together. During the long-term application of this hopper car, since the bottom door often needs to be opened or closed, the joint between the first side bottom door and th...
