Abstract
The invention relates to a transmission chain connecting device. Every chain comprises at least two sections; the adjacent chains are fixedly connected through a connecting device; the connecting device comprises a transitional chain link, a spring piece and split pins; the transitional chain link comprises two oppositely arranged lock plates and two vertical columns which are arranged between the two lock plates; one ends of the vertical columns extend out of the lock plates and are provided with pin holes; the spring piece is arranged between the pin holes and the adjacent lock plate; the split pin is inserted into the pin holes. According to the transmission chain connecting device, double assurance is provided due to the chain lock plates and the opening pins and equipment failure caused by breaking and falling due to the fact that the chains shake during transmission is avoided.
Description
Technical field
The present invention relates to steel rolling equipment technical field, particularly relate to a kind of Transmitted chains chain connection set.
Background technique
Air-cooled roller-way is by chain transmission, and adjacent two Transmitted chainss are fixed by chain joint, and chain joint is originally fixed by spring sheet, the not stationarity of longer and chain transmission in use, and spring sheet easily drops, and causes chain joint to get loose to cause to mistake.Annual before chain joint transformation because locking plate drops, causing mistakes reaches about 5 times, and on cold bed, chain is more, and during running, spot check personnel are difficult to find that spring sheet drops.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of chain and gets loose protective gear, provides double shield to prevent chain from disconnecting and comes off, and solve the fault because chain releasing causes.
For solving the problems of the technologies described above, the present invention relates to a kind of Transmitted chains chain connection set, described chain comprises at least two sections, adjacent chain is fixedly connected with by connection set, described connection set comprises cranked link, spring sheet and cotter pin, two root posts that described cranked link comprises two locking plates be oppositely arranged and is arranged between two locking plates, one end of described column is stretched out locking plate and is arranged pin-and-hole, described spring sheet is arranged between described pin-and-hole and contiguous locking plate, and described pin-and-hole is inserted in described cotter pin.
Preferably, described spring sheet is the ellipse metal plate of one end open, and described opening direction is contrary with chain operation direction.
Preferably, the length direction of described spring sheet is consistent with the length direction of the cranked link of chain.
Preferably, described cotter pin is structure after a steel bar doubling, and after inserting pin-and-hole, steel bar two ends bend backward.
Preferably, the bending angle of described steel bar two ends is 90 °-120 °, is preferably and bends 120 ° backward.
Preferably, the length of described cranked link is 20-50mm, is preferably 30mm.
Preferably, the internal diameter of described pin-and-hole is 3-8mm, is preferably 5mm.
Preferably, the length of described spring sheet is 20-50mm, is preferably 30mm.
Beneficial effect of the present invention is: provide double shield by the design of chain locking plate and cotter pin, avoids the shake of chain when transmission to cause disconnecting and come off and the equipment failure caused.

Embodiment
In order to make object of the present invention, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.It should be noted that, the word "front", "rear" of use is described below, "left", "right", "up" and "down" refer to direction in accompanying drawing, word " interior " and " outward " refer to the direction towards or away from particular elements geometrical center respectively.
See Fig. 1-4, the present invention relates to a kind of Transmitted chains chain connection set, chain comprises at least two sections, and adjacent chain is fixedly connected with by connection set.Connection set comprises cranked link 1, spring sheet 2 and cotter pin 3.Transition chain, 1 comprises two locking plates be oppositely arranged 11 and is arranged at two root posts 12 between two locking plates, and one end of column 12 is stretched out locking plate and arranged pin-and-hole 13, and spring sheet 2 is arranged between pin-and-hole 13 and contiguous locking plate 11, and pin-and-hole 13 is inserted in cotter pin 3.The internal diameter of pin-and-hole 13 is 3-8mm, is preferably 5mm.Cotter pin 3 is structure after a steel bar doubling, and after inserting pin-and-hole 13, steel bar two ends bend backward.The bending angle of steel bar two ends is 90 °-120 °, and the present embodiment is preferably and bends 120 ° backward.
Spring sheet 2 is the ellipse metal plate of one end open, and opening direction is contrary with chain operation direction.The length direction of spring sheet 2 is consistent with the length direction of the cranked link of chain.
The length of cranked link 1 is 20-50mm, is preferably 30mm.The length of spring sheet 2 is 20-50mm, is preferably 30mm.
When this connection set uses, first on cranked link 1, load onto spring sheet 2, then insertion opening pin 3, cotter pin difficult drop-off, reduces chain locking plate 11 and to drop possibility, from installation so far acomia raw chain locking plate 11 to drop situation, ensure the normal operation of chain and roller-way, reduce rate of mistaking.
Be more than better embodiment of the present invention, but protection scope of the present invention is not limited thereto.Any those of ordinary skill in the art are in the technical scope disclosed by the present invention, and the conversion expected without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore the protection domain that protection scope of the present invention should limit with claim is as the criterion.
