Abstract
The utility model relates to a sleeve with two lugs, which belongs to the components and parts of the contact net system of an electrified railroad. The utility model is composed of two semi-circular anchor ears, a U bolt and a bolt pin, wherein, a U bolt slot is arranged on the outer wall of one semi-circular anchor ear along the circumferential direction; both sides of the U bolt slot are provided with convex reinforcing ribs containing the U bolt, the upper and the lower ends of the U bolt slot are provided with bolt holes, and a reinforcing rib is arranged on the outer wall of the other semi-circular anchor ear along the circumferential direction; the upper and the lower ends of the other semi-circular anchor ear are respectively provided with a bolt hole with a lug boss which is positioned at the outer side, the U bolt respectively passes through the bolt holes at the upper and the lower ends, and the semi-circular part of the U bolt is positioned in the U bolt slot; the end head of the U bolt is positioned at the lug boss, and thus the two semi-circular anchor ears are connected.
Description
The utility model relates to a kind of bushing double eye, belongs to electrifing railway contacting net system component manufacturing technology field.
Bushing double eye of the prior art is made up of two identical semicircle sleeve pipe anchor ears and the straight bolt of quadruplet, though sleeve pipe anchor ear forging manufacturability is good.But because four straight bolt strained autobalances that are difficult for, make the anchor ear unbalance stress, be out of shape inconsistently, not only influence clamps effect, and nut screwing clamping retreats to get off sometimes, is difficult to adjustment; Secondly bolt quantity is many, and two spanners of firm all need of each bolt, and installation efficiency is low.
The purpose of this utility model is to design a kind of bushing double eye of new structure, can strengthen detail rigidity guaranteeing that design of part adapts under the prerequisite of forging and molding, improves the part stress situation, guarantees reliability, the Security of part, makes part easier for installation.
The utility model design proposal: the bolt pin that bushing double eye is provided with by its top (1), semicircle sleeve pipe anchor ear (2), (3) and U bolt (4) constitute, along the circumferential direction be shaped on U bolt slot (6) on semicircle sleeve pipe anchor ear (2) outer wall, U bolt slot (6) both sides are shaped on the protruding reinforcing rib (5) that contains U bolt (4), on, the lower end is shaped on bolt hole (7), along the circumferential direction be shaped on stiffening rib (8) on semicircle anchor ear (3) outer wall, on, the lower end is shaped on the bolt hole (10) of band boss (9), and boss (9) is positioned on the semicircle anchor ear (3), the outside, lower end, and bolt hole (7), (10) corresponding, U bolt (4) passes bolt hole (7) and (10) respectively, and make its semi-circular portion be arranged in U bolt slot (6), the termination is positioned at boss (9) to be located, and semicircle anchor ear (2) and (3) are linked together.
Concrete structure is: along the circumferential direction be shaped on twice U bolt slot (6) on semicircle sleeve pipe anchor ear (2) outer wall, upper and lower end is shaped on two bolts hole (7) respectively, two ends, the left and right sides along the circumferential direction are shaped on two stiffening ribs (8) on semicircle anchor ear (3) outer wall, upper and lower end is shaped on the bolt hole (10) of two band boss (9) respectively, and two cover U bolts (4) pass bolt hole (7) respectively and (10) link together two semicircle anchor ears (2) and (3).
The utility model is compared with prior art: the one, and the fastening respectively and Tightening moment of each nut can autobalance; The 2nd, only need one can be fastening spanner for the nut on the U bolt, and are easy for installation; The 3rd, weight not only alleviates 10% than the bushing double eye of existing two halves anchor ear pattern, and owing to be shaped on stiffening rib and U bolt slot on the anchor ear outer wall, and the U bolt is arranged in the U bolt slot, thereby has strengthened its rigidity.
