The utility model has the advantages that: can prevent or reduce the jamming phenomenon to appear, and the busbar can smoothly slide in the anchor section when expend with heat and contract with cold.
Description
Technical field
The present invention relates to track traffic component technology field, especially relate to a kind of sliding load formula rigid insulation suspension apparatus.
Background technology
Stream row rigid suspension system is a kind of important power supply system in track traffic, and bus duct is along line arrangement, for locomotive provides electric power, is its important component part.This bus duct not only stably will be suspended on fixed position, and need can bearing temperature change cause expand with heat and contract with cold.The bus duct of prior art is hung by the steady ear installed on the insulator, and insulator is connected on suspention channel-section steel.This connection mode is slided by the gap between bus duct and steady ear, and what compensation bus duct caused because of temperature traverse expands with heat and contract with cold.But, the hitch point of rigid suspension system is more, due to the finite gap between steady ear and bus duct, when running into the section such as minor radius or heavy grade circuit, glade plane space less in this hang very easily causes bus duct clamping stagnation, cause bus duct to be out of shape, then affect current carrying quality, even cause equipment to lose.
Summary of the invention
The object of this invention is to provide a kind of sliding load formula rigid insulation suspension apparatus, it has to prevent or to reduce and occurs catching phenomenon, and bus duct can slide swimmingly when expanding with heat and contract with cold in anchor section, then making locomotive well be flowed, the feature demonstrate,proving traffic safety can be guaranteed.
The technical solution adopted in the present invention is: sliding load formula rigid insulation suspension apparatus, comprise suspention channel-section steel, insulator, for fixing bus duct, described suspention channel-section steel is connected with 2 sliding load formula suspension brackets, this cunning load formula suspension bracket comprises superposed claw and is positioned at the pressure pin of bottom, after the claw of these 2 sliding load formula suspension brackets is stuck on this suspention channel-section steel, one is had to be linked together by these 2 sliding load formula suspension brackets in the first bolt of level, simultaneously, this insulator top and hardware fitting on insulator are " one " font metal sheet, the both sides portion of this metal sheet is inserted in the top of these 2 pressure pins respectively, the bottom of this insulator is fixed with one in the second vertical bolt, this second bolt is connected on this insulator by one in the steady ear of " U " font, and, this bus duct is fixed on the bottom of this steady ear by 2 the 3rd bolts being connected to 2 avris of this steady ear.
The present invention is advantageously: can prevent or reduce and occur catching phenomenon, and in anchor section, bus duct can slide swimmingly when expanding with heat and contract with cold.Sliding load formula rigid insulation suspension apparatus of the present invention, by changing bus duct at the sliding type of hitch point, reliably solves the clamping stagnation of bus duct.Meanwhile, be linear contact lay between sliding load formula suspension bracket and the metal sheet of insulator, friction force is little; and the gap slided between load formula suspension bracket and the metal sheet of insulator is larger; relative motion both convenient, even if thus have larger expanding with heat and contract with cold, also can guarantee the smooth and easy slip of bus duct.

Detailed description of the invention
Embodiment, is shown in shown in Fig. 1 to Fig. 5: sliding load formula rigid insulation suspension apparatus, comprises suspention channel-section steel 10, insulator 30, for fixing bus duct 50.
Concretely, this suspention channel-section steel 10 is connected with 2 sliding load formula suspension brackets 20.This cunning load formula suspension bracket 20 comprises superposed claw 21 and is positioned at the pressure pin 22 of bottom.The two ends of this pressure pin 22 are fixed on 2 connecting arms 24 extending downwards from the bottom of this cunning load formula suspension bracket 20.After the claw 21 of these 2 sliding load formula suspension brackets 20 is stuck on this suspention channel-section steel 10, first bolt 23 in level is had to be linked together by these 2 sliding load formula suspension brackets 20.Certainly, these 2 sliding 20 points, load formula suspension brackets occupy the both sides of this suspention channel-section steel 10.Meanwhile, this insulator 30 top and hardware fitting on insulator are " one " font metal sheet 31, and the both sides portion of this metal sheet 31 is inserted in the top of these 2 pressure pins 22 respectively.That is, these 2 pressure pins 22 are supported on the both sides of this metal sheet 31.The bottom of this insulator 30 is fixed with one in the second vertical bolt 41, and a steady ear 42 in " U " font is connected on this insulator 30 by this second bolt 41.Obviously, the top of this second bolt 41 is preferably fixed on this insulator 30 bottom, and this steady ear 42 can with this second bolt 41 for axis carries out 360 ° of rotations.And this bus duct 50 is fixed on the bottom of this steady ear 42 by the 3rd bolt 43 having 2 to be connected to 2 avris of this steady ear 42.
Like this, this sliding load formula rigid insulation suspension apparatus, by changing bus duct at the sliding type of hitch point, reliably solves the clamping stagnation of bus duct.Meanwhile, be linear contact lay between sliding load formula suspension bracket and the metal sheet of insulator, friction force is little; and the gap slided between load formula suspension bracket and the metal sheet of insulator is larger; relative motion both convenient, even if thus have larger expanding with heat and contract with cold, also can guarantee the smooth and easy slip of bus duct.
The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize specification sheets of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
