Abstract
The utility model belongs to technical field of electricity, and in particular to a kind of anchor ear.The beneficial effects of the utility model are：The utility model is socketed in semicircle groove through mounting hole by U-bolt and upper anchor ear and lower anchor ear is fixed with nut, simple to operate so that anchor ear installation and removal are convenient, and adheres to firm, it is easy to on-site construction operations；And the setting of plain washer can effectively reduce the frictional force between anchor ear and lower anchor ear, prevent from releasing, strengthen its adhesive force.
Description
Technical field
The utility model belongs to technical field of electricity, and in particular to a kind of anchor ear.
Background technology
The development of China's electric railway in recent years is very fast, the operation of the electrification innovation, Line for Passenger Transportation of old circuit,
Beijing-Shanghai express railway goes into operation, and all the reliability to tractive power supply system proposes higher requirement.To solve applied to high-speed railway touching net
Damage to crops caused by thunder problem, typically now installs parallel connection clearance device at insulator two ends.During normal operation, parallel connection gaps have uniform insulation
The effect of power frequency electric field on son；And after circuit is struck by lightning, higher lightning impulse overvoltage is produced at insulator two ends, due to
The discharge voltage of parallel connection gaps is less than insulator arc-over voltage, the first flashover of parallel connection gaps, and the power frequency short circuiting arc continued is in electromagnetism
In the presence of power and thermal stress, the insulator surface that speeds away moves on parallel connection gaps stable burning, and spatially electric arc is to remote
Develop from insulator direction, protection insulator is from damaging, due to being that air insulation can be from extensive after transient fault, reclosing
It is multiple.
And the installing component of parallel connection clearance device should have enough mechanical strength and keep long-term and installs firm, including
Train run at high speed generation ground base vibration, pantograph lift contact line generation vibration, wire wind load vibration etc. it is many
Plant under stress, be not broken, loosen, come off.Existing installation anchor ear can not meet the demand.
Utility model content
In view of the deficienciess of the prior art, the utility model provides a kind of anchor ear, net-fault vibration interference can be effectively resisted
Loose or dislocation is caused to parallel connection clearance device, it is to avoid the train apparatus and personal security run at high speed are damaged.
The utility model is achieved through the following technical solutions：
A kind of anchor ear, including anchor ear and lower anchor ear in circular arc, the upper anchor ear are provided at both ends with mounting hole, it is described under
The outer surface of anchor ear is provided with semicircular groove, and the upper anchor ear is fixed with lower anchor ear by U-bolt and nut, it is described on
Anchor ear, which is located at the mounting hole, is provided with plain washer.
Further, the U-bolt is socketed in the groove.
Compared with prior art, the beneficial effects of the utility model are：
1st, the utility model by U-bolt be socketed in semicircle groove through mounting hole with nut fix upper anchor ear and under
Anchor ear, it is simple to operate so that anchor ear installation and removal are convenient, and adhere to firm, it is easy to on-site construction operations；
2nd, anchor ear is provided with plain washer at the mounting hole on the utility model, and the setting of plain washer can be reduced effectively
Frictional force when upper anchor ear and the fastening of lower anchor ear between the two, prevents from releasing, strengthens its adhesive force.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In accompanying drawing 1：1. on anchor ear；2. plain washer；3. lower anchor ear；4.U type bolts；5. nut.
Embodiment
A kind of anchor ear as shown in Figure 1, including anchor ear 1 and lower anchor ear 3 in circular arc, upper anchor ear 1 are provided at both ends with peace
Fill hole (not identified in figure), the outer surface of lower anchor ear 3 is provided with semicircular groove (not identified in figure), upper anchor ear 1 with lower armful
Hoop 3 is fixed by U-bolt 4 and nut 5, and upper anchor ear 1, which is located at mounting hole, is provided with plain washer 2.
Further, U-bolt 4 is socketed in groove.
Specifically fastening flow is：U-bolt is first stuck in the semicircle groove of lower anchor ear outer surface, is then passed through anchor ear
Two mounting holes, are tightly squeezed in insulator end flange surface by upper and lower anchor ear by nut, realize reliable attachment, significantly
Increase the stability of integral hoop.
In summary, preferred embodiment only of the present utility model, not implements for limiting the utility model
Scope, the equivalent change carried out by all shape, construction, feature and spirit according to described in the utility model right is with repairing
Decorations, all should be included in right of the present utility model.
Claims (2)
1. a kind of anchor ear, it is characterised in that：Including anchor ear in circular arc and lower anchor ear, the upper anchor ear is provided at both ends with installation
Hole, the outer surface of the lower anchor ear is provided with semicircular groove, and the upper anchor ear is solid by U-bolt and nut with lower anchor ear
Fixed, the upper anchor ear, which is located at the mounting hole, is provided with plain washer.
