Description
Technical field
The utility model relates to the tension stringing construction equipment of overhead transmission line, particularly a kind of bending resistance rotary connector.
Background technology
At present, employed rotary connector in the payingoff construction of overhead transmission line generally is the connection between steel rope and the lead when being used for the anti-twister of steel rope and limp or lead and the anti-twister of limp and exhibition and putting solid conductor.It is bearing under the situation of tension force and can rotate freely by both forward and reverse directions, to discharge the moment of gyration that produces under the various situations.
Spreading conducting wire is drawn via the unwrapping wire reel of tensioner, by being socketed in the net formula adaptor union of wire termination, is connected with rotary connector, and then with after haulage cable is connected, could begins to discharge lead.Because the anti-bending strength of rotary connector is not good, generally all be before connection with rotary connector is arranged in the outlet wheel of tensioner.The defective of this product is can not wear in the lump with lead to walk around straining pulley, and the back twist moment that exists on the lead does not have condition to discharge yet, usually can the net adaptor union that play the lead-in wire effect of lead front end is stubborn bad, be unfavorable for safe construction.
Simultaneously, the end of haulage cable is made circle back cross-under and realize both bonded assemblys on the bearing pin of rotary connector, often because the contact surface of steel rope and bearing pin is little, after steel rope is subjected to pulling force, very easily produce distortion and be drawn as flat, thereby the tensile strength of steel rope is weakened greatly, reduce the service life of steel rope.
Summary of the invention
The purpose of this utility model just is to design a kind of bending resistance rotary connector: it can reduce the length of body, smooth drum by straining pulley, prevented that the back twist moment on the lead from twisting bad net adaptor union, in time discharge the torsion on the lead, reduce steel rope and be connected the deflection that is produced with bearing pin.Its technical scheme is as follows:
The transom that has a pair of symmetry to place, both are connected by steel rope, each transom comprises upper binding head, lower union joint, briquetting, bearing, wheel cover and bearing pin, one end of described upper binding head and lower union joint is socket mutually vertically, the hinged cover of taking turns of bearing pin, its two ends are fixed on the upper binding head, one cylinder cavity is arranged in the lower union joint, be provided with jack hole at the bottom of the chamber, be built-in with briquetting and bearing at described cavity, the two ends of steel rope are connected with briquetting with bearing by jack hole respectively, and briquetting one end under the steel wire rope tension effect is tight against bearing one end face.
The described cover of taking turns is one to be provided with the roller of arc groove.
Described briquetting is one to be provided with the cylinder of through hole, and an end of described steel rope does not axially have and relatively moves the ground cross-under in the described through hole of briquetting.
Described chamber diapire is provided with dustproof groove, and groove is built-in with dust-proof seal ring.
Described upper binding head and the socket of lower union joint can be that between the two spiral is connected.
Described bearing is a plain thrust bearing.
The beneficial effects of the utility model are: 1) connect to realize and the haulage cable direct connection by the net formula adaptor union that is socketed in wire termination, solved existing rotary connector can not be smoothly problem by straining pulley; 2) in time discharge the torsion on the lead, prevented that the back twist moment on the lead from twisting bad net adaptor union, eliminated the potential safety hazard of tension force construction; 3) reduced the length of body, satisfied the requirement of twining by tensioner unwrapping wire reel; 4) simple in structure, on-site installation and operation are very convenient, high efficiency and safe and reliable.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment
1 is the wheel cover among the figure, the 2nd, and bearing pin, the 3rd, upper binding head, the 4th, screw, the 5th, lower union joint, the 6th, briquetting, the 7th, plain thrust bearing, the 8th, steel rope, the 9th, haulage cable, the 10th, transom, the 11st, dust-proof seal ring.
The specific embodiment
Below in conjunction with drawings and Examples the utility model and advantage thereof are described further.
Contrast Fig. 1, a pair of transom 10 symmetries are placed, and both are connected by steel rope 8, like this can be crooked, flexible good, can on straining pulley, reel.Each transom is made up of upper binding head 3, lower union joint 5, briquetting 6, plain thrust bearing 7, wheel cover 1 and bearing pin 2.The one end outside of upper binding head 3 is provided with outside thread, and an end inboard of lower union joint 5 is provided with negative thread, and both are by being threaded.The other end at connector 3 is equipped with bearing pin 2, the hinged cover 1 of taking turns on it.The hinged cover 1 of taking turns is one to be provided with the roller of arc groove, haulage cable 9 increases with the contact surface of wheel cover like this, suffered distortional stress reduces, and simultaneous wheels cover 1 can rotate relative to bearing pin 2, can reduce haulage cable 9 and overlap 1 o'clock suffered tension force being subjected to drawing by taking turns.Lower union joint 5 has a cylindrical cavity, is provided with jack hole at the bottom of the chamber, is built-in with briquetting 5 and plain thrust bearing 7 at this cavity; plain thrust bearing 7 places position at the bottom of the chamber, in order to protect bearing, prevents that foul from entering in the cavity; be provided with dustproof groove at the chamber diapire, groove is built-in with dust-proof seal ring 11.The two ends of steel rope 8 are connected with briquetting 6 by jack hole, bearing on the transom of two symmetry placements respectively.Its connection mode is such: steel rope 8 is connected in the cylindrical hole of cylindrical briquetting 6, again its crimping is become cuboid, make the steel rope 8 and the contact friction force of briquetting 6 increase the generation grip force, and it is connected as a single entity.
In the tension stringing construction of overhead transmission line, steel rope 8 is being tightened up, such two briquettings 6 are under the pulling of steel rope 8, one end is tight against on an end face of plain thrust bearing 7, when the moment of gyration that in construction, produced by the transmission pressure that set up, connected transom 10 is by steel rope 8, briquetting 6 in another symmetrical transom 10 and plain thrust bearing 7 in time discharge during with this moment of gyration, can not have in the technology net adaptor union that plays the lead-in wire effect of lead front end is twisted bad phenomenon, make the tension stringing construction of overhead transmission line more safe and reliable.
