Abstract

An arm-type current collector relates to the improvement of tension current collectors and can reduce the probability that an electric brush goes off the rail and prevent a torsional spring from being released completely. The arm-type current collector comprises an outer cylinder, an inner cylinder, a torsional spring arranged between the outer cylinder and the inner cylinder, a rotating arm, an electric brush, a cable connecting post, a soft conductive band connected with the cable connecting post, a bottom plate and a base plate; the electric brush is movably connected to the head end of the rotating arm; the outer cylinder is fixedly connected with the bottom plate as a whole; a circle of groove is formed on the end surface of the outer cylinder; the tail end of the rotating arm is connected to the shaft head of the inner cylinder; a guide pin for extending into the groove is arranged on the arm body of the rotating arm in the position corresponding to the groove of the outer cylinder; and a phase block used for restricting the operation range of the guide pin is arranged in the groove on the end surface of the outer cylinder. The phase block in the utility model can restrict the rotating arm to ensure that the rotating arm can only rotate within 360 degrees, in other words, the pulling force of the torsional spring can be restored only by pulling the rotating arm back simply, further, the contact tension of the electric brush and the conducting wire/guide rail of an electric device can be ensured; besides, the rotating arm can be rotated to adjust the elastic force of the torsional spring.

Description

Arm-type current-collector

Technical field

The utility model relates to the current collecting equipment that current collection side in a kind of trolley system is picked up electric energy, relates in particular to the improvement to the tension force current-collector.

Background technology

The trolley current-collector is the main device that the current collection side is picked up electric energy in the trolley system, and it is directly conducted to electrical appliance by the sliding contact of collecting brush and guide rail with electric energy, thus the mobile power supply of the system of realization.The trolley current-collector is made up of the tensioner of mechanical structure and collecting brush two parts of direct and guide rail sliding contact.

The tensioner determined set brush of mechanical structure and the sliding contact pressure and the mechanism stability of guide rail, collecting brush then is the conductor that electric energy is picked up in the guide rail sliding contact.In the occasion with vibration, pulsation operation, the contact reliability between collecting brush and the electrical appliance is the key factor of decision systems overall operation situation.

For guaranteeing to contact reliably between collecting brush and the electrical appliance, the elastic force that utilizes the torsion spring technical scheme as contact tension force was once arranged, it has urceolus, inner core, be located between the two torsion spring, support the parts such as pivoted arm of brush.Its inner core is fixed, the urceolus activity, and pivoted arm is connected on the urceolus.Find the current-collector of this version in the use, owing to need the bracing frame of inner core,, make that whole trolley system occupation space is big so whole height is bigger.The applicant has proposed the technical scheme that inside and outside tube motion is exchanged by research and development, has reduced the height of product greatly, and then has saved the space.But find, owing to electrical appliance lead/rail because of expand with heat and contract with cold, reason such as little turning, can cause brush " to be overstepped the limit ".And in case brush is overstepped the limit, the torsion spring can discharge fully.Thereby need bigger maintenance load.

The utility model content

The utility model provides a kind of derailed probability that reduces brush at above problem, and the arm-type current-collector of avoiding the torsion spring to discharge fully.

The technical solution of the utility model is: comprise urceolus, inner core, be located at torsion spring between urceolus and the inner core, pivoted arm, brush, cable joint pin, the soft conductive strips, base plate and the seat board that join with described cable joint pin, described brush is movably connected in the head end of described pivoted arm, described urceolus and described base plate are connected to one, and the end face of described urceolus is provided with a circle groove;

The tail end of described pivoted arm is connected in the spindle nose of described inner core, is provided with the guide finger that is used to stretch into described groove on one's body at the arm of the corresponding described urceolus groove of described pivoted arm;

Be provided with a phase block that is used to limit described guide finger range of operation in the groove of described urceolus end face.

Described pivoted arm is provided with a pair of, is connected on the spindle nose at described inner core two ends; The outer end of described pivoted arm links to each other by a connecting rod that is parallel to described inner core axle center, and described brush is movably connected on the described connecting rod.

Described phase block is located at described groove top and is partial in the groove of described conductive strips direction.

Be provided with porcelain insulator between described base plate and the seat board, the upper and lower end of described porcelain insulator is equipped with the connection screw, and described connection screw surface is provided with the antistatic insulating layer of sand that infiltrates 0.5-5mm in the described porcelain insulator bottle.

Current-collector of the present utility model, end face is provided with a circle groove outside, at the pivoted arm middle part guide finger is set, pivoted arm is as having motion with respect to urceolus, then guide finger, groove limit both motions as guide rail structure, and then improve the scope of pivoted arm head end brush motion, avoid occurring " overstepping the limit " phenomenon.If the phenomenon of overstepping the limit takes place, the rotation that phase block in the utility model can limit pivoted arm is no more than 360 °, that is to say, only needs simply pivoted arm to be retracted, can recover the pulling force of torsion spring, and then guarantee the tension force that contacts between brush and the electrical appliance lead/rail.In addition, phase block can be dismantled temporarily, dismantles the connecting rod of pivoted arm head end again, promptly rotatable pivoted arm, and then the elastic force of adjustment torsion spring.The utility model can be realized the free adjustment of elastic force, can increase nearly one times adjustment amplitude than current-collector in the past, add it is both arms, the parts of connection have fixing rail groove control, the phenomenon so more can not jump onto the tracks, bullet (turning round) power spring is given tension force of rotation axis (inner core) all the time, has guaranteed the steady dispensing of electric power.
