Description
Technical field
The present invention relates to electric railway technologies, more particularly to a kind of skill of the thread-off prevention line pantograph for electric locomotive
Art.
Background technology
Contact net is the transmission line of electricity for the special shape powered to electric locomotive that downline overhead is set up, outstanding by contacting
It hangs, device, positioning device, pillar and several parts in basis is supported to form.
Contact suspension includes contact line, dropper, carrier cable and union piece, and contact suspension is by supporting device to be erected at
On pillar, function is the electrical energy transportation that will be obtained from traction substation to electric locomotive.Device is supported to support that contact is outstanding
It hangs, and its load is transmitted to pillar or other buildings.Positioning device be used for by contact line be limited to pantograph by electric slide plate
Within the scope of running orbit, ensure that the pantograph of contact line and electric locomotive does not depart from, and the level load of contact line is transmitted to branch
Column.Pillar, to bear whole loads of contact suspension, support and positioning device, contact suspension is fixed on defined with basis
On position and height.
Contact net is responsible for is delivered directly to the vital task that electric locomotive uses the electric energy obtained from traction substation,
The quality and working condition of contact net will directly affect the transport capacity of electric railway, therefore the design requirement of contact net is
In any condition, it can ensure to supply electric power locomotive electric energy well, ensure that electric locomotive safety on the line, high speed are transported
Row, and reduce investment outlay as much as possible, is reasonable for structure, repairing simplicity, convenient for the application of new technology.
Pantograph is the current collection device of the electric locomotives such as high ferro and subway, on the roof of electric locomotive, pantograph
Be arch conductive plate by electric slide plate, what is contacted with contact line by electric slide plate is covered with carbon item on one side, can reduce the mill to contact line
Damage, and the carbon dust generated that rubs can be used as lubrication and use.For example same spring of pantograph, can persistently be bestowed after rising bow cable to
Upper strength, enable in pantograph by electric slide plate abutting contact line, electric power is obtained from contact line, and can connecing according to different height
It touches line and adjusts rising bow height.
It can be seen that the reliable contacts between by electric slide plate and the contact line of contact net of pantograph, are to ensure electric power machine
Vehicle well takes the essential condition of stream.Existing pantograph is all bent downward by electric slide plate both ends bow corner, the reason is that being
It avoids in electric locomotive traveling process, the foreign matter that the unconventional appearance in contact line both sides is encountered by electric slide plate of pantograph.
Since the contact line in contact net can be expanded with heat and contract with cold with the variation of environment temperature, the contact line of adjacent two intercolumniations
Midpoint（That is the minimum point of contact line）Height can also change with expanding with heat and contract with cold for contact line, when summer heat expansion in contact line
Point place can highly reduce, and contact line midpoint height can increase when winter shrinkage.If the branch intercolumniation design of contact net was spaced
It is long, the midpoint of the contact line of adjacent two intercolumniations can be caused to drop amplitude more than by the one of electric slide plate length in summer heat expansion
Half（Bent cadre midpoint to the distance for bending corner by electric slide plate, the bow cadre is the horizontal component by electric slide plate）, due to
Existing pantograph is all bent downward by electric slide plate both ends bow corner, and when encountering lateral high wind, contact line is possible to meeting
It is influenced by lateral high wind, skids off pantograph, be detached from by electric slide plate, so as to cause electric locomotive disconnection fault.So contact
The spacing that branch intercolumniation must be limited when net design, to define the struts number in unit length, also so that over long distances
The contact net circuit construction cost of railway is high.
Invention content
Defect present in for the above-mentioned prior art can be prevented technical problem to be solved by the invention is to provide a kind of
Long contact line skids off pantograph, so as to reduce the struts number in contact net unit length, and then can reduce electrification
The thread-off prevention line pantograph for electric locomotive of railway contact line line construction cost.
In order to solve the above-mentioned technical problem, a kind of thread-off prevention line pantograph for electric locomotive provided by the present invention, packet
It includes by electric slide plate, described by electric slide plate is arch conductive plate that left and right ends are bent downward, it is characterised in that：It further include pedestal；
Be pivoted with each bracket that can be pivoted up and down around on the pedestal, the pivot axis of the bracket perpendicular to by
The bow of electric slide plate is dry, and a telescopic hook that can be horizontally slipped respectively is housed on two brackets, and the pedestal is equipped with for driving two
The lifting driver part that a bracket pivots up and down, and the telescopic drive component for driving two telescopic hooks to horizontally slip；
Each one of left and right is housed to open for triggering the fine motion of lifting driver part, the operation of telescopic drive component on the pedestal
It closes, left microswitch is located at the underface of left tray, and the on ＆ off switch of left microswitch resists the bottom surface of left tray, and right fine motion is opened
Off-position is in the underface of right bracket, and the on ＆ off switch of right microswitch resists the bottom surface of right bracket；
The left end of left telescopic hook extends to the left bow corner by electric slide plate and is folded upward to the left, the right end of right telescopic hook to
The right side extends to the right bow corner by electric slide plate and is folded upward at, and the bow by electric slide plate is dry to be higher than pedestal, bracket and telescopic hook,
And the right end of the left end of left telescopic hook and right telescopic hook being pivoted up with bracket, be moved to higher than being bent by electric slide plate
It is dry.
Provided by the present invention for the thread-off prevention line pantograph of electric locomotive, using bracket and telescopic hook can effectively block by
Lateral high wind is blown to the contact line for being bent corner by electric slide plate, and can push back contact line and be bent cadre by electric slide plate, is avoided that contact
Line with by electric slide plate be detached from, therefore the branch intercolumniation spacing of contact net can design it is relatively long so that contact net unit length
Therefore interior struts number is also accordingly reduced, can be effectively reduced the contact net circuit construction cost of electric railway.
