The right-angle edge of the angle iron is located on the axial cross section of the hoop, and the included angle between the right-angle edge of the angle iron and the axis of the hoop is equal to the taper of the outer surface of the electric pole. The horizontal keeping device has the advantages of being stable in structure, simple in using mode and capable of effectively guaranteeing that the cross arm is horizontal.
Description
Technical field
The utility model relates to power system application, relates in particular to the improvement to keeping the device of the level of cross-arm on electric pole to propose.
Background technology
At present, cross-arm is one of common accessory of electric pole, for providing a fixed bearing to devices such as insulators, cross-arm structure of the prior art has a lot, representative portion " high-low voltage leads cross-arm " by name, the application number as State Bureau, on February 19th, 2014, announced are the document of " 201310555999.1 ", and the cross-arm in this case is connected on electric pole by anchor ear and cushion block.Yet, very easily there is tilting in use the phenomenon of (one side that is cross-arm is high low) on one side in this type of cross-arm, if cross-arm keeps tilting for a long time, the Joint failure of electric wire and insulator will be caused, serious will directly pull cross-arm and anchor ear under the impact of laying particular stress at it, exists high potential safety hazard and extremely low application life.
Utility model content
The utility model is for above problem, provides a kind of Stability Analysis of Structures, mode of occupation simple, and during use, cross-arm can remain the horizontal holding device of cross-arm on the electric pole of level.
The technical solution of the utility model is: the external surface of described electric pole has tapering, described horizontal holding device comprises anchor ear, contiguous block and some angle steel, and the plane that described anchor ear is fixedly connected on cross-arm middle part and anchor ear place by contiguous block is parallel with described cross-arm;
Some described angle steel are all fixedly connected on the inner ring of described anchor ear by cushion block and are uniformly distributed along the axle center of anchor ear;
The right angle edge of described angle steel is positioned on the shaft section of described anchor ear and the angle in the right angle edge of angle steel and the axle center of described anchor ear equals the tapering of the external surface of described electric pole.
The angle in the right angle edge of described angle steel and the axle center of described anchor ear is 5-15 °.
Described anchor ear comprises the anchor ear one that is semicircle shape and the anchor ear two that is semicircle shape, and described anchor ear one is fixedly connected with described cross-arm by contiguous block, and described anchor ear two is dismountable to be connected on anchor ear one.
In described angle steel, be provided with foam filler.
On the root edge of described anchor ear, be also fixedly connected with supplemental cartridge, described supplemental cartridge be straight-tube shape and with described anchor ear concentric, the root edge of described supplemental cartridge is fixedly connected with the bottom of some described angle steel.
When the utility model is used, can be directly by anchor ear empty set on electric pole, then drive its integral body to glide along electric pole by operating personnel, until all angle steel are all fitted on the external surface of electric pole.Now, because the angle in the right angle edge of angle steel and the axle center of described anchor ear equals the tapering of the external surface of described electric pole, so can guarantee that the axle center of anchor ear keeps vertical; In addition the plane at anchor ear place is parallel with cross-arm, and then can guarantee cross-arm level.Make this case have advantages of that Stability Analysis of Structures, mode of occupation are easy, can effectively guarantee cross-arm level.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the top view of Fig. 1,
Fig. 3 is use state reference map of the present utility model;
In figure, 1 is electric pole, the 10th, and cross-arm, the 2nd, anchor ear, the 21st, anchor ear one, 22nd, anchor ear two, 3rd, contiguous block, the 4th, angle steel, the 40th, cushion block.
The specific embodiment
The utility model as Figure 1-3, the external surface of described electric pole 1 has tapering, described horizontal holding device comprises anchor ear 2, contiguous block 3 and some angle steel 4, and the plane that described anchor ear 2 is fixedly connected on cross-arm 10 middle parts and anchor ear 2 places by contiguous block 3 is parallel with described cross-arm 10;
Some described angle steel 4 are all fixedly connected on the inner ring of described anchor ear 2 (cushion block being welded between the right angle edge and the inner ring of anchor ear of angle steel) and are uniformly distributed along the axle center of anchor ear 2 by cushion block 40;
(angle steel conventionally steel identical by two chip sizes and that be connected as a single entity forms the right angle edge of described angle steel 4, between two steel, be 90 °, right angle edge is herein the intersecting lens of two steel) be positioned on the shaft section of described anchor ear 2 and the angle in the right angle edge of angle steel 4 and the axle center of described anchor ear 2 equals the tapering of the external surface of described electric pole 1.
The angle in the right angle edge of described angle steel 4 and the axle center of described anchor ear 2 is 5-15 °.
Described anchor ear 2 comprises the anchor ear 1 that is semicircle shape and the anchor ear 2 22 that is semicircle shape, and described anchor ear 1 is fixedly connected with described cross-arm 10 by contiguous block 3, and described anchor ear 2 22 is dismountable to be connected on anchor ear 1.
In described angle steel 4, be provided with foam filler.After anchor ear, angle steel integral installation, can in angle steel, fill the foam filler of being made by expanded material, and it is foamed in angle steel, thus the stability of effective winding level holding device integral body, maintenance intensity and application life.Like this, when installing insulating and electric wire, cross-arm can not produce because of unbalance stress inclination yet.
On the root edge of described anchor ear 2, be also fixedly connected with supplemental cartridge, described supplemental cartridge be straight-tube shape and with described anchor ear 2 concentrics, the root edge of described supplemental cartridge is fixedly connected with the bottom of some described angle steel 4.Like this, can complete more simply, efficiently by the cooperation of cushion block and supplemental cartridge the fixing of some angle steel, and after horizontal holding device integral installation completes, strengthen the support to angle steel, and then effectively promote whole Stability and dependability.
