Abstract

The invention discloses a supporting insulator used for the installation and fixation of rigid power supply lines, which consists of an upper metal accessory (1), an insulator (2) and a lower metal accessory (3), wherein at least one metal accessory (1 or 3) is provided with a conical surface (1a or 3a) used for space installation and positioning. The supporting insulator can realize space adjustment within larger scope in a smaller space and accurate positioning and locking, and is simple, quick, steady and reliable in connection positioning.

Description

A kind of supporting insulator

Technical field

The present invention relates to a kind of insulator that rigidity supply line installs, fixes that is used for, be mainly used in installation, the support fixation of power rail.

Background technology

Insulator by this type is commonly referred to as supporting insulator or supporting insulator, according to using character to be divided into common supporting insulator (having along power rail length to slide relative between power rail and insulator) and anchoring insulator again, its effect is that the spatial attitude to power rail retrains fixing and the realization electric insulation.

Prior art, comprise flexible contact line and the rigid contact net support of (containing conductor rail, conductor rail, power rail, power rail) (or support) insulator, it can not lean on insulator self attachment function implementation space millimeter with other accurately location, the locking of interior level when connection.It is relatively poor that basis (as built-in fitting) precision usually is installed, and power rail will realize high-precision installing and locating, needs more bolt and other annex, and it is low that loaded down with trivial details efficient is installed, and reliability is poor.The magnetic floating traffic counter-lateral quadrents is flowed the installation accuracy of power rail and is had higher requirement, the installation and control precision is in millimeter, installing space is little, it is bigger that basic civil engineering built-in fitting site error is installed, adjusting adaptive capacity and external dimensions to insulator have harsher requirement, so the inherent shortcoming of aforementioned dielectric seems particularly outstanding in the magnetic floating traffic rail system.

Summary of the invention

The objective of the invention is to solve the problems of the technologies described above, a kind of novel supporting insulator that is used for power rail is provided, can in less space, realize in a big way space adjustment and accurately location, locking, connect location simple and fast, reliable and stable.

Technical solution of the present invention is:

A kind ofly be used for the supporting insulator that rigidity supply line installs and fixes, constitute by annex under annex, insulator, the metal on the metal; It is characterized in that having at least to have the taper seat that is used for the space mounting location on the metal-ware.

Preferentially, the taper seat load of watering that is positioned at metal-ware and insulator connects beyond the zone.

Preferentially, following annex is a revolving body.

Preferentially, taper seat inside is provided with bolt or the internal thread that is connected and fixed usefulness.

Preferentially, outer conical surface has anti-slop serrations.

Preferentially, internal conical surface has stop notch.

Preferentially, all have the taper seat that is used for the space mounting location on the metal-ware, the taper seat axis is not parallel to each other.

Preferentially, be used for the angle that intersects after the axes intersect of taper seat of space mounting location or the translation at 45～135 °.

Preferentially, two taper seats are respectively inside and outside taper seat or are all internal conical surface or outer conical surface.

The invention has the beneficial effects as follows:

By the installation taper seat at supporting insulator two ends and cooperating of corresponding connector (5,6), and the boss of taper seat, recess location, the snap-in location of taper seat serration has realized the positioning locking of the circumferential and axial at insulator two ends, and connecting bolt is reduced to one at a minimum end.These useful designs have overcome the deficiencies in the prior art, make the connection locking at insulator two ends more precisely reliable, and constructing operation simplifies significantly, easy for installation, safeguard simple.

Embodiment

Embodiment 1:

Common as shown in Figure 1 supporting insulator, insulator 2 upper ends are the last annex 1 that has conical bore 1a, and the lower end is the following annex 3 that has taper seat 3a, have serration 3b above the following annex taper seat 3a.

As shown in Figure 6, the conical surface axle that will be installed on the fastener of annex on the insulator penetrates in the taper hole 1a of annex 1, fastener aligns with the recess 1b of last annex taper hole 1a and embeds around horizontal rotational shaft to the boss on the fastener conical surface then, power rail hangs on the fastener gib head that keeps flat in advance, after the fastener cone axis penetrates the annex conical bore, the chimeric position of the direction of rotation of fastener and boss, recess all is unique, rotateing in place the back just can be chimeric, the locking axial and circumferential, power rail also is mounted the location simultaneously, need not other measurement, contraposition.

Behind fastener and last annex 1 location,, make conical surface locking to add the chimeric of convex platform and recess, guaranteed that fastener can not become flexible, and more can not rotate in long-term use by fastening stop nut.

As shown in Figure 7, following annex 3 tail end surfaces are provided with toothed frustum of a cone 3a, and mating surface is fitted mutually behind the support lower end circular cone counterbore of packing into, can adapt to whole insulator along the circumferentially requirement of optional position.

After the circumferential position of the relative support of following annex was definite, fastening bottom thread connected the nut above the 3c, and following annex is installed the serration 3b and the mutual interlock of the support counterbore conical surface of frustum-conical surface, located in axial and circumferential between annex and the support under realizing.

Embodiment 2:

Anchoring insulator as shown in Figure 2, insulator 2 upper ends are the flat annex 1 ' of going up that has installing hole, and the lower end is the following annex 3 that has taper seat 3a, has serration 3b above the following annex taper seat 3a.

Use 4 bolts to be installed on flat annex 1 ' the corresponding installation site of going up the anchoring buckle that is threaded the hole.Behind anchoring buckle and the last annex 1 ' location, be fastenedly connected bolt, make on anchoring buckle and the insulator annex installed surface accurately locate and be connected fastening.
