Description
Technical field
The utility model is related to the installing areas of current collector for trolley conductor, more particularly to a kind of current collector for trolley conductor is adjustable
Mounting bracket.
Background technology
Power-supply trolley line apparatus is made of slide-wire guide rails and current collector for trolley conductor (hereinafter referred to as current-collector).Wherein, slip
Guide rail is fixed part, is connected with power supply, and usual slide-wire guide rails are formed by connecting by the rail guide piece for singly growing 6 meters/root；Current-collector is
Slipper in slip track or interior sliding and can realize contact electricity getting, collecting brush and the driving inlet wire cable of current-collector
Line is connected.
Current-collector is the main device of pickup electric energy in current collection side in sliding contact line system, it passes through the sliding of collecting brush and guide rail
Electric energy is directly conducted to driving power distribution cabinet power switch, to realize the mobile power supply of system by contact.Current-collector is tied by machinery
The tensioner of structure and directly with collecting brush two parts of guide rail sliding contact form.
Although in the prior art current-collector itself can by adjustment spring pulling force connecing come adjusting slider and trolley
Touch pressure, but in actual mechanical process, due to the influence of environmental factor or mounting condition, the adjusting only according to current-collector itself has
When cannot be guaranteed suitable contact, this has some setbacks the sliding block for leading to current-collector and trolley planar slide and current-collector
With slide-wire guide rails poor contact, lead to the case where collecting brush generates arcing with trolley in driving operational process.It causes safety-type
The copper conductor contact surface arcing of trolley " H " type is burnt and irrecoverable, and the trolley service life is seriously affected.When vehicling operation movement away from
From length, it is improper that current-collector is installed or configured, and easily causes derailed current-collector, card resistance, poor contact, will lead to collector damage or use
In the current-collector holder damage of installation current-collector, causes the significant trouble of the whole trolley power failure that collapses, it is suitable to influence produced on-site operation
Row.
Driving is that the common cargo of workshop and factory is carried and lifting equipment, along be set to workshop or
The travelling crane sliding touch wire track of industrial building eminence is run, and the power-supply trolley line apparatus of prior art middle rolling car is using aluminium or copper
Alloy trolley, three-phase are installed side by side, and the current-collector holder of driving is welded on the normal place driven a vehicle below trolley, by current collection
Device penetrates on holder, and adjusts the parallel distance of current-collector and trolley.Copper carbon blade slide plate is on current-collector holder, directly
It connects and contacts conduction with trolley.
There is a situation where collector damage sum aggregate electric supports in driving produce reality application is drawn bad by stress, causes to set
Standby shut down influences produced on-site direct motion.The current-collector supporting structure of above-mentioned travelling crane sliding touch wire, since long-term excess load use is drawn
It is uneven to play trolley rail height, deformation is serious, causes Crane Rail vibration problem that can not eliminate, current-collector holder following vehicle shakes
It moves and beats；Simultaneously because site environment is poor, the stand spring on current-collector holder, which will soon be corroded, to be got rusty and loses
Active force；In addition, since holder is beated, and then copper carbon slide plate is caused to be beated, with trolley poor contact, conductive short interruptions are drawn
Arc, to easily form arc tumor arc crater in trolley, thus vicious circle, high failure rate, maintenance is time-consuming and laborious, and makees in driving
Industry is dangerous, seriously affects production.
In the prior art, used at present in view of the influence of the factors such as live actual environment situation, technological requirement, cost
Safety-type current collector for trolley conductor is installed on fixing bracket, adjusts the feelings needed when contact of the current-collector with trolley in power-off
It is carried out under condition, it cannot be guaranteed that the contact that current-collector is balanced with trolley, especially restricts the practicality.Safety-type trolley by
Factor of expanding with heat and contract with cold deforms, and driving moves back and forth long distance running, and the pressure change that current-collector holder is born is big, leads to current-collector
Damage or current-collector holder are bent by stress stretch bending, influence driving normally by electricity.It is restricted extensively using property
