Description
Technical field
The utility model relates to a kind of current-collector, relates in particular to the special-purpose current-collector of a kind of trolley.
Background technology
At present, the general current-collector that adopts of the safety sliding contact line on the market is all-in-one-piece, for example: patent 90221687.2, a kind of safety slip electric transmission device.Although current-collector contacts with the transmission of electricity guide rail with the dolly form, advantages such as flexible, safe, reliable, energy-conservation are arranged, but when mobile devices such as the overhead and gantry cranes that uses, electric block automatic carriage, movable electric tool need overhaul, because the current-collector dolly can not be taken out from guide rail, so that the power supply of this equipment can not cut off, therefore when trolley safe in utilization, need set up the maintenance section, to guarantee maintenance safety.For making repair apparatus can enter the maintenance section safely, often need on the safety sliding contact line guide rail one in front and one in back two current-collectors are installed, this not only increases investment, has also reduced the benefit that safety sliding contact line uses, and also is inconvenient to overhaul.
Traditional current-collector is the manual splicing of aluminium bar, and following three defectives are arranged: one, with high costs, and inefficiency; Two, size often has discrepancy, when 3 or 8 current-collectors are used in combination, can increase the difficulty of installing and the instability of operation because of the deviation of size; Three, when putting malposition, easily cause the risk of taking off groove.
The utility model content
The purpose of this utility model provides the special-purpose current-collector of a kind of trolley, to overcome with high costs, the inefficiency of traditional current-collector, difficulty and fluctuation of service is installed when being used in combination, and easily causes the deficiency of taking off groove.
The purpose of this utility model is to be achieved through the following technical solutions:
The special-purpose current-collector of a kind of trolley, comprise installing rack, support bar and brush protective cover, described installing rack comprises left installing rack and the right installing rack that is connected by two pairs of reverse long handle screws, two relative middle parts, side of installing rack all form the prismatic hole, described right installing rack is equipped with the triangular plate that turns up in both sides up and down, and two triangular plate middle parts of turning up are installed with seamless steel pipe; Described installing rack connects support bar by seamless steel pipe, the lower surface of support bar is provided with jockey near the end, one end of extension spring is connected with described jockey, the other end of extension spring passes slotted hole on the support bar and connects another jockey that is located at the seamless steel pipe upper end, the top of described support bar right-hand member connects the U-shaped rocking bar by screw, and the two ends of U-shaped rocking bar connect described brush protective cover; Brush protective cover lower surface is provided with the cable efferent duct, and the middle part of brush protective cover is provided with the protection intermediate plate, and the inboard of protection intermediate plate is provided with brush and connects copper bar, and brush connects copper bar and is provided with brush plate.
The beneficial effects of the utility model are: 1, compared with prior art, newly-increased U-shaped rocking bar makes the brush plate of current-collector rotate adjustment by 360 degree, it is in operation can adjusts angle voluntarily, guarantees the contact-making surface maximization with trolley; 2, current-collector center brush protective cover and protection intermediate plate are for strengthening fire-retardant nylon, except that brush plate and nylon part, a complete set is the die stamping moulding, guarantee the meticulous of size and work in coordination, guarantee the stability and the fluency of current-collector operation, simultaneously when 3 or 8 current-collectors are used in combination, the difficulty of avoiding traditional current-collector to increase installing and the unsettled deficiency of operation because of the deviation of size; 3, extension spring guarantees that brush contacts with the stable of trolley inside groove; 4, installing rack use very flexible, according to different instructions for uses, can be separately or in parallel the use, simple installation not only during in parallel use the, and efficiently solve traditional current-collector and need use two to overlap the problem that installing racks too take up space and increase cost; 5, the unique texture of support bar, not only slim and graceful, saved installing space, avoided the possibility of control cable or other optional equipment collision friction especially, effectively increase the service life; 6, brush connects the use of copper bar, not only guarantee the brush plate installation closely, it is overheated and scald the nylon protective cover to prevent in the brush plate running, and the distinctive ductility of red copper more plays the function that connects output (control) cable and brush plate for trickle the expanding with heat and contract with cold of brush provides necessary extendable room.
