Embodiment 1

[0031] Such as figure 1 and figure 2 , a transport flat car, including a car body, a buffer device and a side door 4, the side door is installed on the upper surface of the side beam 21 of the car body.

[0032] Wherein, the buffer device includes a connecting hinge 1, a hinged seat 2, an iron stop 3, a compression nut 9, and two arched seats 17.

[0033] The hinged seat 2 is fixed on the backing plate 20, the backing plate 20 is fixed on the side beam 21, and the upper end of the connecting hinge 1 is fixed on the side door 4; set, and connected through the hinge pin 5; the hinge pin 5 is sleeved with a first spring 6 and a second spring 7, the first spring 6 and the second spring 7 are respectively located on both sides of the hinge seat 2, the first spring 6 and the The direction of rotation of the second spring 7 is opposite.

[0034] Both ends of the arched seat 17 are fixed on the side door 4, and the two arched seats 17 are respectively located on both sides of the ...

Embodiment 2

[0038] A buffer device for the side door of a transport flat car, in the case that the other connecting structures are the same as those in the first embodiment, it also includes a limiting device fixed on the lower part of the side beam 21 . Such as image 3 and Figure 4 As shown, the limit device includes a support 10, a stop 12 and a third spring 15. One end of the support 10 is fixed to the lower part of the side beam 21, and the other end is provided with a U-shaped groove 11, and the stop 12 is arranged in the U-shaped groove. 11, the support 10 and the stop 12 are connected through a cylindrical pin 13, the end of the cylindrical pin 13 is provided with a cotter pin 16, and a second washer 19 is also provided between the cotter pin 16 and the support 10; the upper part of the stop 12 The outer side is an inclined surface 22, and a through hole 14 is opened on the stopper 12 located below the inclined surface 22, and the through hole 14 extends from the front side of t...

Abstract

The invention belongs to a port line transportation flatcar. Technical problems that when the transportation flatcar additionally provided with a side door is used, after the side door is opened, an operator is easily injured; meanwhile, after the side door is opened and rotates, a side beam and the side door are impacted, and deformation of the side beam and the side door is caused are solved. The transportation flatcar comprises a car body, a buffer device and the side door. The buffer device comprises a connecting hinge, a hinge base, stop iron and pressing nuts. The hinge base is fixed tothe side beam, and the upper end of the connecting hinge is fixed to the side door; the hinge seat, the lower end of the connecting hinge and the stop iron sequentially sleeve from outside to inside and are connected through a hinge pin; the hinge pin is provided with a first spring and a second spring, one end of the first spring and one end of the second spring are connected to the side door, and the tail ends of the other ends are horizontally bent and connected to the hinge base; the two end surfaces of the first spring and the two end surfaces of the second spring are buckled with a pairof end covers; and the pressing nuts are in threaded connection with the two ends of the hinge pin and press the first spring and the second spring to the two sides of the hinge base correspondingly.

Description

technical field [0001] The invention belongs to an auxiliary device for a port line transport flat car, in particular to a transport flat car. Background technique [0002] In addition to transporting large volumes of materials such as steel rails, sleepers, and turnouts, port lines also need to transport granular goods such as gravel. When transporting granular goods, some types of transport flat cars need to be equipped with side doors to avoid the scattering of granular goods. [0003] At present, because the side door of the transport flat car with the flip side door is generally heavy, the side door often rotates after opening. If it is not fixed in time or buffered to limit the position, it is very easy to cause injury to the operator. At the same time, the rotation of the side door will directly hit the side door. Attachments on beams and side beams can easily cause deformation of side beams and side doors. Contents of the invention [0004] The present invention ...
