Abstract
The present utility model discloses a brush holder with adjustable tension force. The brush holder comprises a supporting pedestal (1) and a spring (3), a rectangular brush holder is formed by two long supporting rods (2) and two wide supporting rods (4), the supporting pedestal (1) is connected with one wide supporting rod (4), a carbon brush slide block is arranged on the top end of the other wide supporting rod (4), one end of the spring (3) is fixed on the right end of a long supporting rod (2) of the lower part, the other end is connected with a tension force adjusting device, the tension force adjusting device is arranged on the left end of a long supporting rod (2) of the upper part, and the tension force adjusting device is composed of a pedestal (5) and an adjusting screw (6). In the brush holder, a self-made stainless steel current collector is adopted, tension force adjusting is increased, fulcrum arm force is lengthened, wear rate of the current collector is reduced, service life is increased, slide wire burning-out accident rate is reduced, and vast overhauling funds can be saved.
Description
Technical field
The utility model relates to a kind of current-collector.
Background technology
The existing overhead traveling crane that uses, current-collectors such as thickener are aluminium alloy and working of plastics is made, and Lian Dianduo wears no resistance, and have several respects defective in the use: one, working of plastics is many, and is easy to wear.Two, intensity of aluminum alloy is not enough, and useful life is short.Three, tensile force can not be regulated.Cause that respectively to organize slip tension force inhomogeneous, cause slide block, carbon brush wearing and tearing uneven, cause slip to be ablated, draw bad current-collector and other slips, directly influence the normal operation of equipment.
Summary of the invention
The technical problem that the utility model will solve: the current-collector brush holder that can adjust tension force that provides a kind of stainless steel to make, to solve the existing defective that overhead traveling crane, current-collector above the thickener exist that is used in.
The technical scheme of the utility model:
A kind of tension adjustable brush holder comprises supporting seat, spring, and two long fulcrum bars and two wide poles constitute the rectangle brush holder; Supporting seat is connected with a wide pole; The carbon brush slide block is installed on the top of another wide pole, it is characterized in that: spring one end is fixed on the below and props up long right-hand member, and the other end is connected with tension adjusting device; Tension adjusting device is located at the left end of the pole of top, is made up of pedestal and adjustment screw.
The manufacturing materials of whole brush holder is a stainless steel.
The beneficial effect of the utility model:
Reduce the working of plastics tie point, adopt self-control stainless steel current-collector, increase the tension adjustment and the lengthening fulcrum arm of force, reduced the current-collector wear rate, increase its useful life, reduce slip and burn out rate of failure, save a large amount of maintenance funds.
Description of drawings:
Fig. 1 is the utility model sketch map.
Embodiment:
Embodiment: the brush holder of rectangle is made up of 2 long fulcrum bars 2 and 2 wide poles 4, and wide pole 4 left sides in left side are connected with supporting seat 1, and wide pole 4 upper ends on right side are used to install the carbon brush slide block.The left side of the long fulcrum bar 2 of upside is equipped with tension adjusting device, is made up of pedestal 5 and adjustment screw 6, and an end of spring 3 is connected the right-hand member of downside long fulcrum bar 2, and the other end is connected with adjustment screw 6.Whole brush holder is made by stainless steel material.
Through turning the position of adjustment screw 6 in pedestal 5, just can reach the purpose of adjustment spring tension.
Claims (2)
1. tension adjustable brush holder; Comprise supporting seat (1), spring (3); Two long fulcrum bars (2) and two wide poles (4) constitute the rectangle brush holder, and supporting seat (1) is connected with a wide pole (4), and the carbon brush slide block is installed on the top of another wide pole (4); It is characterized in that: spring (3) one ends are fixed on the right-hand member of below long (2); The other end is connected with tension adjusting device, and tension adjusting device is located at the left end of the pole (2) of top, is made up of pedestal (5) and adjustment screw (6).
2. tension adjustable brush holder according to claim 1 is characterized in that: the manufacturing materials of whole brush holder is a stainless steel.
