Abstract
The utility model relates to a hinged ring of a sleeve tube, belonging to the components and parts of the contact net system of an electrified railroad. The utility model is composed of the anchor ear of the sleeve tube, a hinged ring ear and a U bolt, wherein, a U bolt slot is arranged on the outer wall of the anchor ear of the sleeve tube along the circumferential direction; both sides of the U bolt slot are provided with convex ribs; the anchor ear of the hinged ring has an integral structure which is formed by that the lower end of a semi-circular anchor ear is connected with the upper end of a hanging plate; a reinforcing rib is arranged on the outer wall of the semi-circular anchor ear along the circumferential direction; the U bolt respectively passes through bolt holes arranged at the upper and the lower ends of the anchor ear of the sleeve tube and the anchor ear of the hinged ring to connect the anchor ear of the sleeve tube and the anchor ear of the hinged ring. Under the premise that the structures of parts can be ensured to be forged to be formed with reliability, the utility model reduces the numbers of the parts, enhancing the rigidity of the parts, improving the stress condition of the parts, ensuring the safety and the reliability of the parts, and enhancing the work efficiency of installation.
Description
The utility model relates to a kind of sleeve with clevis and ring, belongs to electrifing railway contacting net system parts manufacturing technology field.
Sleeve with clevis and ring of the prior art is made up of two ears anchor ears and a hinge ring link plate, connects together by the straight bolt of quadruplet, and is clamped on the pipe, the forging manufacturability of part is good, but four bolt strained self-equalizings that are difficult for make the anchor ear unbalance stress, be out of shape inconsistent, not only influence clamps effect, and nut screwing clamping retreats to get off sometimes, is difficult to adjust, secondly, number of parts is many, and inconvenience is installed, and work efficiency is low.
The objective of the invention is to design a kind of sleeve with clevis and ring of new structure,, reduced number of parts guaranteeing that design of part can adapt under the prerequisite of Forging Technology, strengthened detail rigidity, improve the part stress situation, guaranteed the safety and the reliability of part, improved installation efficiency.
Design plan of the present utility model: the bolt pin that sleeve with clevis and ring is provided with by the top (1), a semicircle sleeve pipe anchor ear (2) and a hinge are encircled hoop (3) and U bolt (4) formation, along the circumferential direction be shaped on U bolt slot (6) on sleeve pipe anchor ear (2) outer wall, U bolt slot (6) both sides are shaped on the protruding reinforcing rib (7) that contains U bolt (4), hinge is encircled the integral structure of hoop (3) for connecting together on semicircle anchor ear (8) lower end and the link plate (9), along the circumferential direction be shaped on reinforced rib (10) on semicircle anchor ear (8) outer wall, on the sleeve pipe anchor ear (2), the lower end is shaped on bolt hole (11) respectively, hinge is encircled on the hoop (3), the lower end is shaped on the bolt hole (12) of band boss (13) respectively, boss (13) is positioned at hinge and encircles on the hoop (3), the outside, lower end, and bolt hole (11), (12) corresponding, U bolt (4) passes bolt hole (11) respectively, (12) and be arranged in U bolt slot (6), sleeve pipe anchor ear (2) and hinge being encircled hoop (3) links together.
Concrete structure is: along the circumferential direction be shaped on twice U bolt slot (6) on sleeve pipe anchor ear (2) outer wall, two ends, the left and right sides along the circumferential direction are shaped on two reinforced ribs (10) on semicircle anchor ear (8) outer wall, sleeve pipe anchor ear (2) upper and lower end is shaped on two bolts hole (11) respectively, hinge is encircled the bolt hole (12) that hoop (3) upper and lower end is shaped on two band boss (13) respectively, and two overlap U bolts (4) passes bolt hole (11), (12) respectively and sleeve pipe anchor ear (2) and hinge are encircled hoop (3) link together.
The utility model and prior art and ratio: the one, adopt the U bolt to clamp, and the U bolt is arranged in the U bolt slot and is the face contact, each nut is distinguished fastening, Tightening moment energy self-equalizing, part stress is even, and clamps effective, reliability height, nut are difficult for killing on bolt, easily adjust; The 2nd, part is the structure of dividing right and left, and bolt only is subjected to the Tightening moment effect, and does not bear the additional pulling force that part transmits, the reliability height; The 3rd, the U bolted only needs one spanner, the installation efficiency height; The 4th, a slice anchor ear and link plate are an integral body, and are shaped on reinforced rib on the anchor ear outer wall, and number of parts is reduced, weight saving, and cost reduces, and has increased the strength and stiffness of anchor ear.
