2 to Fig. 5 the application is described in further details with reference to the accompanying drawing.
A kind of chocking construction, comprising:
Braking roll 1, wall surface offer at least one locking groove；
Stop cylinder 2, is set in braking roll, and inner wall covers locking groove at least one protrusion, stop cylinder 2；
Multiple arc-shaped stop sections 3, the one or more arc-shaped stop sections 3 of the interior setting of a locking groove；Wherein,
Braking roll 1 is moved toward one another with stop cylinder 2, makes the side of any arc-shaped stop section side and a stop trough wall surface
It contradicts, the side of the other side and at least one stop protrusion wall surface contradict.
Further, locking groove only has one, and opens up along braking roll 1 is circumferential, in a ring, referred to as annular stop slot.
Further, in annular stop slot setting there are two arc-shaped stop section, one of them be known as first it is arc-shaped only
Dynamic section, another is known as the second arc-shaped stop section；Central angle corresponding to first arc-shaped stop section is located within 180 degree；
Central angle corresponding to second arc-shaped stop section is located within 180 degree.The central angle of arc-shaped stop segmental arc is limited in 180
Installation of the arc-shaped stop section in locking groove can be facilitated within degree.
Further, the central angle of the first arc-shaped stop section is equal to 180 degree；The central angle etc. of second arc-shaped stop section
In 180 degree；First arc-shaped stop section forms locating snap ring with the second arc-shaped stop section.By the center of circle of the first arc-shaped stop section
The central angle of angle and the second arc-shaped stop section, which is arranged to one annular composition locating snap ring of 180 degree composition, can limit it in locking groove
It inside moves in the circumferential direction, reduces abrasion, and make stable structure.
Further, stop protrusion only one, and along the circumferential setting of stop cylinder 2, in a ring, referred to as annular stop is convex
Out.The design of above-mentioned setting cooperation locating snap ring can effectively increase conflict area, reduce the stress value of unit area, to make this only
