Description

A kind of collector shoe sliding block adjusting horizontal position

Technical field

The utility model relates to the current collecting equipments in vehicle powering system, it particularly relates to which a kind of raising collector shoe is sliding The wear-resisting property of block adjusts the collector shoe sliding block of horizontal position.

Background technique

Current collecting equipment is the key part of urban light rail and subway, it is related to the normal fortune of train dynamics trailer system Turn, directly affects the utilization rate and train smooth safe operation of electric energy.Subway is generally adopted by third rail electric means, leads The electric power for drawing power supply system is transported on railcar by the current collecting equipment contacted with third rail, driving traction electric machine rotation and Train is set to advance.As shown in Fig. 1, the connection bolt length of current collecting equipment stretches out bracket in the prior art, and bolt is easy and ground It scratches, the hard objects such as the stone on ground are easy to hit collector shoe, and security reliability reduces；Collector shoe sliding block is fixed simultaneously Rack-mount, horizontal position is not adjustable, and contacts friction, and distance with subway third rail always during the work time Ground is closer, and the flatness and cleannes to third rail have higher requirement；The contact slipper of vehicle current collecting equipment is general simultaneously All using materials such as copper, iron, the electric conductivity of brass is preferable, it is small to wear away to third rail, but wearability is poor, railcar contact Quickly, consumption is huge, and economic cost is higher for the copper sliding block abrasion of sliding block；Ferrous material is cheap, as iron steel friction Pair, wearability is good, and service life is longer, but cast iron sliding block can cause more serious abrasion to third rail, increase to third rail Damage.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, provides and a kind of improve the resistance to of collector shoe sliding block Performance is ground, realizes the structure that collector shoe sliding block horizontal position is adjusted.

To realize the above-mentioned technical purpose, the utility model is achieved through the following technical solutions:

A kind of collector shoe sliding block adjusting horizontal position, including carbon slider body, the bottom of the carbon slider body are swallow Stern construction, and be fixed on attachment base, carbon slider body is stretched out in the both ends end of attachment base and the upper surface of bracket passes through T shape spiral shell It tethers and connects, the upper surface of bracket offers multiple grooves, offers on the bottom of carbon slider body and attachment base and table on bracket The slot that face groove matches, is provided with elastomer between groove and slot, carbon slider body may be implemented on horizontal position Adjusting.

Further, the bottom surface of the carbon slider body is rectangle.

Further, the elastomer is spring.

Further, the shape of the groove and slot is circle, and quantity is 4-8.

Further, the material of carbon slider body is D type Graphite Iron Cast.

Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, in carbon sliding block sheet The slot for accommodating elastomer is offered between body and bracket, realizes adjusting of the carbon slider body on horizontal position；Simultaneous selection A kind of material of functional, low-cost D type Graphite Iron Cast as carbon slider body, improves the wear-resisting of collector shoe sliding block Property, service life is extended, economic cost is reduced.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the prior art.

Fig. 2 is the structural schematic diagram of the utility model.

Specific embodiment

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain The utility model is not used to limit the utility model.

As shown in Fig. 2, a kind of collector shoe sliding block of adjusting horizontal position according to the utility model embodiment, including The bottom of carbon slider body 1, the carbon slider body 1 is dovetail configuration, and is fixed on attachment base 2, the both ends end of attachment base 2 Portion stretches out carbon slider body and is connect with the upper surface of bracket 3 by tommyhead bolt 4, and the upper surface of bracket 3 offers multiple grooves 5, The slot 6 matched with 3 upper surface groove of bracket, groove 5 and slot 6 are offered on the bottom of carbon slider body 1 and attachment base 2 Between be provided with elastomer, adjusting of the carbon slider body on horizontal position may be implemented.

Carbon slider body 1 is fixed with attachment base 2 by dovetail configuration, and the dismounting and change of carbon slider body 1 is facilitated to pacify Dress, attachment base 2 are directly anchored to bracket 3 by tommyhead bolt 4, avoid connection bolt and stretch out bracket, scratch with ground, It is more safe and reliable；The slot matched with 3 upper surface groove of bracket is offered on the bottom of carbon slider body 1 and attachment base 2 6, it is provided with elastomer between groove 5 and slot 6, carbon slider body and the Elastic Contact friction of subway third rail are realized with this, more Add the operation adapted under third rail difference operating condition, while also achieving adjusting of the carbon slider body on horizontal position, tommyhead bolt Plain cushion and spring washe is equipped between 4 and attachment base 2.

Specifically, the bottom surface of the carbon slider body 1 is rectangle.

Specifically, the elastomer is spring.

Specifically, the shape of the groove 5 and slot 6 is circle, and quantity is 4-8.

It in order to further increase the wearability of collector shoe sliding block, improves service life, reduces economic cost, do not increasing pair Under the premise of third rail abrasion loss, material of functional, the low-cost D type Graphite Iron Cast of one kind as sliding block is selected.Casting Graphite shape is affected to its frictional behaviour in iron material, and graphite shape has A in gray cast iron, and B, C, D etc. is several, wherein A type For flake graphite, graphite structure is thicker, is easy cracking；The utility model is D type graphite, D using more satisfactory graphite structure Type graphite is that interdendritic is dotted, organize it is thinner, it is not easy to crack, the graphite fine particles that D type graphite is ground off can to collector shoe sliding block with Lubricating action is played in friction between conductor rail, and the metals such as molybdenum, titanium are properly added in cast iron can greatly increase D type in alloy cast iron The content of graphite.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection scope within.
