Description
Technical field
The utility model relates to a kind of riser chain, particularly relates to a kind of riser chain with flat gesture hole.
Background technique
Chain is the strength member of board chain hoisting machine, carrier bar with flat gesture hole routinely processing method carrier bar easily produces stress concentration point at the endoporus of the carrier bar of straight line and circular hole, causes carrier bar to ftracture in actual use and cause equipment accident through stress concentration point of being everlasting.In addition, with plate chain as traction enhancement conveying industries, bearing pin, sleeve and the interior outer plate connected separately are fixing can not works in relative rotation, and if any relatively rotating, chain plate hole will soon be large and cause carrier bar to come off chain inefficacy by mill.The carrier bar of circular hole causes because the reasons such as machining error are easy to make bearing pin and sleeve loosen and relatively rotates.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of riser chain with flat gesture hole, can avoid producing stress concentrate and cause carrier bar to ftracture or fracture, and ensure that bearing pin and sleeve do not rotate at chain plate hole internal fixtion when promoting operation, and installing/dismounting is very convenient.
The utility model is solve the problems of the technologies described above the technological scheme adopted to be to provide a kind of riser chain with flat gesture hole, comprise the Chain plate that more piece is connected successively, wherein, described every pitch chain batten comprises two outer plates be oppositely arranged and two inner plates be oppositely arranged, the two ends of described outer plate and inner plate are flattened oval shape, and described outer plate and inner plate are provided with flattened oval hole; Be connected by bearing pin between described two adjacent outer plates and inner plate, be provided with sleeve outside described bearing pin, described outer plate is positioned at the outside of inner plate.
The above-mentioned riser chain with flat gesture hole, wherein, the head of described bearing pin and sleeve is flattened oval shape, and head and the described flattened oval hole of described bearing pin and sleeve match, and the two ends semicircle orifice in described flattened oval hole and the joint of intermediate hole are arc transition section.
The above-mentioned riser chain with flat gesture hole, wherein, interference connection is carried out at semicircle orifice place, two ends in the flattened oval hole on the head of described bearing pin and outer plate.
The above-mentioned riser chain with flat gesture hole, wherein, interference connection is carried out at semicircle orifice place, two ends in the flattened oval hole on the head of described sleeve and inner plate.
The utility model contrast prior art has following beneficial effect: the riser chain in what the utility model provided have flat gesture hole, the endoporus of interior outer plate is all set to flattened oval hole, produces stress concentrate and cause carrier bar to ftracture or rupture in the jointing place arc transition thus can avoid of straight line and circular arc.In addition, outer plate in the utility model is adjacent with sleeve connection by the bearing pin with flattened oval shape head, thus can ensure that bearing pin and sleeve do not rotate at chain plate hole internal fixtion when promoting operation, and installing/dismounting is very convenient, interference connection is carried out at semicircle orifice place, two ends in flattened oval hole on bearing pin and sleeve head and carrier bar, carry out Spielpassung in flat gesture part, can ensure that bearing pin and sleeve do not rotate at chain plate hole internal fixtion better.

Embodiment
Below in conjunction with drawings and Examples, the utility model will be further described.
Fig. 1 is the riser chain structure schematic diagram that the utility model has flat gesture hole; Fig. 2 is the pin shaft structure schematic diagram in the utility model riser chain; Fig. 3 is the tube-in-tube structure schematic diagram in the utility model riser chain; Fig. 4 is the link plate structure schematic diagram in the utility model riser chain
Refer to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the riser chain in what the utility model provided have flat gesture hole comprises the Chain plate that more piece is connected successively, wherein, described every pitch chain batten comprises two outer plates be oppositely arranged 1 and two inner plates be oppositely arranged 4, the two ends of described outer plate 1 and inner plate 4 are flattened oval shape, and described outer plate 1 and inner plate 4 are provided with flattened oval hole 5; Be connected by bearing pin 2 between described two adjacent outer plates 1 and inner plate 4, be provided with sleeve 3 outside described bearing pin 2, described outer plate 1 is positioned at the outside of inner plate 4.
The riser chain in what the utility model provided have flat gesture hole, wherein, the head of described bearing pin 2 and sleeve 3 is flattened oval shape, head and the described flattened oval hole 5 of described bearing pin 2 and sleeve 3 match, and the two ends semicircle orifice in described flattened oval hole 5 and the joint of intermediate hole are arc transition section 6.In on original carrier bar, the diameter of circular hole is D, and the arc transition section 6 being R1 by radius is now connected to form flat gesture hole, thus generation stress can be avoided to concentrate and cause carrier bar to ftracture or fracture.
The riser chain in what the utility model provided have flat gesture hole, the endoporus of interior outer plate all arranges flattened oval hole 5, thus generation stress can be avoided to concentrate and cause carrier bar to ftracture or fracture, and adjacent interior outer plate is connected with sleeve 3 by the bearing pin 2 with flattened oval shape head, thus can ensure that bearing pin and sleeve do not rotate at chain plate hole internal fixtion when promoting operation, and installing/dismounting is very convenient.
In addition, in order to ensure that bearing pin and sleeve do not rotate at chain plate hole internal fixtion better, interference connection is preferably carried out at semicircle orifice place, two ends in the flattened oval hole 5 on the head of described bearing pin 2 and outer plate 1.Similarly, interference connection also can be carried out at semicircle orifice place, two ends in the flattened oval hole 5 on the head of described sleeve 3 and inner plate 4.Interference connection is carried out at semicircle orifice place, two ends in flattened oval hole 5 on bearing pin 2 head and carrier bar, Spielpassung is carried out in flat gesture part, arc surface is utilized to feel relieved, flat gesture face positions, can ensure that bearing pin and sleeve do not rotate at chain plate hole internal fixtion better, effectively prevent bearing pin and sleeve from relatively rotating.
Although the utility model discloses as above with preferred embodiment; so itself and be not used to limit the utility model; any those skilled in the art; not departing from spirit and scope of the present utility model; when doing a little amendment and perfect, therefore protection domain of the present utility model is when being as the criterion of defining with claims.
