Drawings

In order to more clearly illustrate the technical solution of the embodiments of the present invention, the drawings used in the description of the embodiments are briefly introduced below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and other drawings can be obtained by those skilled in the art without inventive efforts, wherein:

fig. 1 is a schematic structural view of a preferred embodiment of the turnover type buffer car arrester of the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1, an embodiment of the present invention includes:

a turnover type buffer car arrester comprises a base 1, a positioning cylinder 2, a positioning plate 3, a stop block 4, a stop spring 5 and a positioning stop block 6.

Wherein, base 1 is hollow structure setting and the top in the middle of the correspondence be provided with avoid the groove 7 for placing and convenient the rotation of whole part.

The inside wall of the base 1 is transversely hinged with a positioning cylinder 2 through a first rotating shaft 8, and the positioning cylinder 2 is used for driving the blocking mechanism to move from the base to the blocking position.

The bottom of the positioning plate 3 is provided with a turning seat 9 and is hinged and fixed on two sides of the avoiding groove 7 through a second rotating shaft 10, so that the positioning plate 3 can rotate around the second rotating shaft 10.

The expansion end of locating plate 3 is provided with arc 11, and the articulated drive end that is provided with springiness buffer gear and fixes a position cylinder 2 on the arc 11 corresponds and is connected, through the 3 upset actions of the drive locating plate of location cylinder 2.

Elastic buffer mechanism includes first connecting block 12, buffer spring 13 and second connecting block 14, first connecting block 12 is articulated to be fixed on the fourth pivot 15 of arc 11, and second connecting block 14 corresponds the drive end of fixing at location cylinder 2, correspond through buffer spring 13 between first connecting block 12 and the second connecting block 14 and connect, location cylinder 2 is when drive arc 11, by first pivot 8 and fourth pivot 15 common adjusting position. The buffer spring 13 has high strength and is capable of extending and contracting in only one compression direction.
