Embodiment Construction

[0032] The embodiment of the present invention provides a bottom door opening and closing mechanism with an adjustable door opening gap, which solves the technical problem that the bottom door opening and closing mechanism in the prior art cannot adjust the opening of the bottom door due to the disappearance or wear of the mechanism gap, and realizes the guarantee The technical effect of the normal opening and closing of the bottom door.

[0033] The technical solution in the embodiment of the present invention is to solve the above-mentioned technical problems, and the general idea is as follows:

[0034] By adjusting the length of the adjustable connecting rod, the adjustment of the gap between the bottom door and the funnel mouth is realized, thereby avoiding the excessive opening of the bottom door, and not only avoiding the collision between the bottom door opening arm and closing arm and the touch table The generated force changes, ensuring the normal opening and closing...

Abstract

The invention discloses a bottom door opening and closing mechanism with adjustable door opening space. The bottom door opening and closing mechanism with the adjustable door opening space comprises a door opening arm, a door closing arm, a main shaft and an adjustable connecting rod, wherein the main shaft is connected with the door opening arm and the door closing arm; the main shaft is also connected with the adjustable connecting rod; the adjustable connecting rod is connected with a bottom door; and when the door opening arm touches a door opening touch table, impact force is transmitted to the adjustable connecting rod by virtue of the main shaft to enable the adjustable connecting rod to move, so as to close the bottom door. The bottom door opening and closing mechanism with the adjustable door opening space has the advantages that space between the bottom door and a hopper opening is adjusted by adjusting the length of the adjustable connecting rod, so that opening of the bottom door can not be too large, change of a force produced by collision between the door opening arm and the door closing arm of the bottom door and the touch table is prevented, normal opening and closing of the bottom door is guaranteed, and leakage rate of cargo is reduced.

Description

technical field [0001] The invention relates to the technical field of railway freight transport, in particular to a bottom door opening and closing mechanism with adjustable door opening clearance. Background technique [0002] At present, the railway hopper car is widely used as one of the main vehicles for transporting mineral powder, grain and other goods, and it mainly adopts the structure of loading and unloading. In order to meet the needs of fast unloading products, a bottom door opening and closing device is installed at the funnel opening at the bottom of the car body. The opening and closing of the bottom door can be realized quickly and accurately through the door opening and closing touch platforms set on both sides of the road. In particular, it plays a very good supporting role in the operation mode of unmanned operation of modern intelligent loading and unloading yards. [0003] Most of the existing railway wagons adopt the connecting rod type embedded bott...
