Abstract
The invention discloses a conductive travelling wheel bracket structure comprising a lower bracket and an upper bracket, wherein the upper bracket is connected with a trolley body; an elastic body is connected between the upper bracket and the lower bracket; the lower bracket is provided with a travelling wheel; the upper bracket, the lower bracket, the travelling wheel and the elastic body are all made from conducting materials; and a locking bolt is connected between the upper bracket and the lower bracket. By adopting the structure, because the elastic body is connected between the upper bracket and the lower bracket, the upper bracket and the lower bracket are in contact stress states all the time, therefore the smooth conduction of currents is ensured; and because the locking bolt is connected between the upper bracket and the lower bracket, when the upper bracket horizontally rotates, the lower bracket synchronously rotates with the upper bracket, therefore a spring can not generate the condition of being instantaneously separated from a contact surface due to the relative motion of the upper bracket and the lower bracket so as to ensure that when an electric trolley passes through a curve road, the currents acquired by the travelling wheel can be smoothly conducted to the electric trolley.
Description
[technical field]
The present invention relates to a kind of supporting construction, especially for the supporting construction of vehicle conduction travelling wheel.
[background technology]
In the prior art, the travelling wheel supporting structure generally is provided with a support below the conduction dolly, a travelling wheel is installed on this support, and travelling wheel is walked on the track that arranges in advance, this structure generally only can be walked, can not walk combines with conducting electricity, and has some travelling wheels to conduct electricity, but electric conductivity is not good, often only be used for the straight way walking, walk bend and still will make walking and separate with conduction, and existing conduction walks the fault rate height of wheel construction, maintenance is difficulty comparatively also.
[summary of the invention]
The technical problem to be solved in the present invention provides a kind of conduction and walks wheel construction with the conduction that walking combines, and not only is applicable to away straight way, and can walks bend too.
The present invention solves the technical scheme that existing technical matters adopts: a kind of conduction travelling wheel supporting structure is provided, comprise lower bracket and the upper bracket that links to each other with car body, be connected with elastic body between described upper bracket and the described lower bracket, described lower bracket is equipped with travelling wheel, and described upper bracket, lower bracket, travelling wheel, elastic body are made by conductive material.
After adopting this spline structure, owing to be connected with elastic body between upper bracket and the lower bracket, the upper and lower two stands that makes is in the contact strained condition always, guarantees the smooth conducting of electric current.
The present invention further improves, and is connected with lock bolt between upper bracket and the lower bracket.After adopting such structure, when upper bracket horizontally rotates, lower bracket also rotates thereupon synchronously, spring just the situation of contact surface can not occur leaving because of upper and lower support relative motion moment like this, when having guaranteed motor-driven carrier by bend, the electric current that travelling wheel collected can be transmitted on the motor-driven carrier smoothly.
The present invention further improves, and upper bracket is provided with one, and described axle outside face is set with bearing.
The present invention further improves, and bearing is a radial thrust bearing, and described radial thrust bearing is two.
After adopting such structure, when motor-driven carrier passes through bend, no matter its car body and upper bracket are end float misalignments up and down, or left and right sides radial-play, radial thrust bearing can well absorb corresponding power, and this motor-driven carrier that just makes can easier pass through bend, and all is less to the damage of its support still to its car body when being subjected to the external force of all directions, reduce the fault rate of support, increased the service life of motor-driven carrier.
[description of drawings]
Fig. 1 is that the scheme drawing of travelling wheel supporting structure is conducted electricity in the present invention.
[specific embodiment]
According to Fig. 1 as can be known, a kind of conduction travelling wheel supporting structure, the upper bracket 14 that it comprises lower bracket 15 and links to each other with car body, be connected with coil spring 18 between upper bracket 14 and the lower bracket 15, lower bracket 15 is equipped with travelling wheel 6, and upper bracket 14, lower bracket 15, travelling wheel 6, coil spring 18 are made by conductive material.This travelling wheel 6 contacts with strip conductor, strip conductor with current delivery to travelling wheel 6.Be connected with lock bolt between upper bracket 14 and the lower bracket 15.Owing to be connected with coil spring 18 between upper bracket 14 and the lower bracket 15, the upper and lower two stands 14,15 that makes is in the contact strained condition always, guarantee the smooth conducting of electric current, and upper and lower support 14,15 is connected with lock bolt, when upper bracket 14 horizontally rotates, lower bracket 15 also rotates thereupon synchronously, coil spring 18 just the situation of contact surface can not occur leaving because of 14,15 relative motion moments of upper and lower support like this, when having guaranteed motor-driven carrier by the strip conductor bend, the electric current that travelling wheel 6 is collected can be transmitted on the motor-driven carrier smoothly.
Be provided with one 16 in the upper bracket 14, be set with two radial thrust bearings 17 at axle 16 outside faces.When motor-driven carrier when the bend, its car body and upper bracket 14 no matter be about end float misalignment, or left and right sides radial-play, radial thrust bearing 17 can well absorb corresponding power.
Car body links together by the axle 16 on a bolt and the upper bracket 14.When this conduction travelling wheel supporting structure et out of order, as long as car body and upper bracket 14 bonded assembly bolts are turned on, car body is sling a little, whole conduction travelling wheel supporting structure will be separated with car body, replacing with failure-free conduction travelling wheel supporting structure then gets final product, the maintenance that such structure makes is convenient, and has shortened maintenance time greatly, has improved work efficiency.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
