Abstract

The utility model relates to a drivepipe hinge ring used in the electrization railway contact line system; with the structural key points that the utility model includes a sleeve with clevis and ring body with ear-rings and a U-shaped bolt matched with the body, a double ear structure which is connected with the body as a whole is arranged above an upper bolt hole, the center line of a double ear groove is accordant or basically accordant with the center line of the axes of the body, the internal inner circle of the U-shaped bolt is matched with the inner circle of the clasping hoop of the body, forming a constant radius rounded staple bolt structure which is just jointed with the nipped excircle wall of the tubular component. The utility model obviously reduces the number and the whole weight of the components, making the whole structure more simple and compact, increasing the strength and the fixing efficiency, in addition, the structure is in favor of making the die forging, having a low cost of manufacture.

Description

A kind of sleeve with clevis and ring

The utility model relates to a kind of sleeve with clevis and ring, particularly relates to a kind ofly being applicable to the contact nets in electrified railways system and being installed in sleeve with clevis and ring on the oblique wrist and arm tubular piece.

Traditional sleeve with clevis and ring is assembled after adopting casting, and its heaviness, the utmost point are not easy to install.A kind of sleeve with clevis and ring (see figure 1) is arranged in the prior art, it by two and half anchor ears 1 ', 2 ' inhale two U-bolts 3 ' form earrings 4 ' be connected as a single entity with one of them half anchor ear.This structure has two characteristics, the one, circle does not contact with folded tube wall in the U-bolt, but is entrenched in the bolt slot of half anchor ear parts, and these half anchor ear parts are a baroque part beyond doubt, both influence alleviating of overall weight, also influenced installation efficiency simultaneously; The 2nd, the ears structure is to lean on the auricle 5 of two halves anchor ear ' installation back to cooperate to form, and the gap during owing to installation in two auricles has uncertainty, brings regulating plate that inconvenience is installed.

At above-mentioned situation, the purpose of this utility model is to provide a kind of amount of parts few, easy to manufacture, and the sleeve with clevis and ring of failure-free again easy for installation.

The technical scheme that realizes above-mentioned purpose is, the utlity model has the hinge ring body of band earrings, is furnished with U-bolt on the upper and lower bolt hole of body, body be positioned at upper bolt hole above be provided with the ears structure that is connected as a single entity with it, line of centers of the ears groove on the ears consistent with the body longitudinal axis (promptly overlapping) or basically identical, ears axially bored line and earrings axially bored line and bolt hole parallel axes, the interior circle of U-bolt cooperates the circular anchor ear structure of radiuses such as formation with the interior circle of body hoop, can just fit with the cylindrical wall of folded tubular piece.The utility model is connected as a single entity earrings and ears and its body, and integrally-built amount of parts is greatly reduced, and the body construction of band ears and earrings, has good forging manufacturability simultaneously, and the mould forging is more or less freely; Adopt U-bolt directly to hold tubular piece tightly, both can reduce amount of parts and overall weight, also can make to install and become very easy and reliable, again because U-bolt has little deformability, when fastening, U-bolt produces little sex change, and opening width diminishes, can obviously improve integrally-built compactedness and anchor ear intensity, make sleeve with clevis and ring bigger, more reliable the gripping power of tubular piece such as oblique wrist and arm; Have again to adopt on the body ears structure directly is set, the ears groove remains definite clearence degree, make it that regulating plate is installed on ears and become very easy, ears connection company headquarters part is subjected to two halves anchor ear sheet that the problem of the not enough influence of quality of fit is installed always thereby fundamentally solved in the past.

The inner arc surface of above-mentioned body hoop respectively with ears and earrings between curved the connection, its mould forges easy to manufacture; Body has breach in the inboard that is positioned at bolt hole.Offer breach, both be convenient to U-bolt and interted, be convenient to the processing of bolt hole again, prolonged the contacting surface of sleeve with clevis and ring and folded tubular piece simultaneously, guaranteeing has enough sliding loads between hinge ring and the tubular piece.

Another constructional feature of the utility model is, establishes reinforced rib on the outer rim of body hoop, ensure under the intensity situation and can cut down its wall thickness to be implemented in, thus further expendable weight; The U-bolt section can adopt circular face structure or rectangular surfaces structure.

From as seen last, the utility model adopts on the body ears structure and the direct anchor ear tubular piece of U-bolt directly is set, obviously reduce component number and overall weight, made total become more succinct and compact, thereby improved intensity and installation efficiency (because installation strength obviously reduces); In addition, the utlity model has good forging manufacturability, be beneficial to the die forging manufacturing, manufacturing cost reduces.

Further specify the utility model structure below in conjunction with Figure of description.

The utility model sleeve with clevis and ring (seeing Fig. 2-6), hinge ring body 2 with direct band earrings 1, the body middle part is a body hoop 3, the upper and lower side symmetry of body has two groups of (totally 4) bolts hole 4, body be positioned at upper bolt hole 4 above be provided with ears 5 structures that are connected as a single entity with it, ears groove 6 line of centerss on the ears overlap consistent (or basic coincidence), ears hole 7 axis on the ears and bolt hole 4 parallel axes with body longitudinal axis Y; The inner arc surface of the hoop 3 of body respectively with curved connection the between the ears 5 of bolt hole upper and lower and earrings 1, body 2 has breach 8 in the inboard that is positioned at upper and lower bolt hole 4, breach 8 bottoms are platform; On body hoop outer rim, be provided with reinforced rib 10; On two groups of bolts hole, be combined with two U-bolts 11, the compasses lattice are identical with folded tubular piece specification in the U-bolt 11, circle divides the circular anchor ear structure that cooperates radiuses such as formation with the hoop inner circular part of body in this U-bolt, can just be close to the cylindrical wall of folded tubular piece 12 and close (referring to Fig. 2), behind fastening nut 13, U type screw combines with the body hoop and directly hugs hoop tubular piece 12, and the U-bolt section can be circular face, rectangular surfaces or class rectangular surfaces.The longitudinal slot structure be can offer on the hoop inner headed face of the utility model body, power and sliding load held tightly with raising.Straight bolt 9 on the ears hole 7 of the utility model ears can directly connect required individual member---regulating plate 14 (see figure 7)s, regulating plate 14 connecting bore 15 be connected on the straight bolt 9 on the ears hole.The utility model is used for the contact nets in electrified railways system, mainly is applicable to above oblique wrist and arm to be connected and fixed bracket and to hang hook type saddle with the earrings type component.
