Abstract
The invention relates to the technical field of a pantograph, in particular to a low-friction-resistance electric locomotive pantograph which comprises a roller, wherein roller shafts are symmetrically arranged at two ends of the roller, one end of each roller shaft is in key connection with the inside of the roller, the other end of each roller shaft extends out of the roller and is sleeved with a bearing, a bearing sleeve is arranged outside each bearing, a roller support is arranged on each bearing sleeve, each roller support is connected with an insulating plate, and a supporting rod is arranged between the two insulating plates.
Description
Technical Field
The invention relates to the technical field of a pantograph, in particular to a low-friction-resistance pantograph of an electric locomotive.
Background
The power required by a rail electric locomotive running in a mine tunnel or working face is the current provided by a locomotive wire erected above a rail in parallel. The pantograph arranged on the electric locomotive does horizontal sliding motion relative to the locomotive line in the same direction as the running direction of the electric locomotive, and the pantograph generates larger friction resistance and generates more sparks during running of the electric locomotive, so that materials such as overhead lines, the pantograph and the like are seriously damaged, the maintenance times and the cost are increased, and the service lives of the overhead lines and the pantograph are greatly shortened.
Disclosure of Invention
According to the defects in the prior art, the technical problems to be solved by the invention are as follows: the low-friction-resistance electric locomotive pantograph solves the problems of large friction resistance, more sparks and serious abrasion, ensures the safety of the electric locomotive in operation and reduces the maintenance times.
The low-friction-resistance electric locomotive pantograph comprises a roller, roller shafts are symmetrically arranged at two ends of the roller, one end of each roller shaft is in key connection fit in the roller, the other end of each roller shaft extends out of the roller and is sleeved with a bearing, a bearing sleeve is arranged outside the bearing, a roller support is arranged on the bearing sleeve and is connected with an insulating plate, and a supporting rod is arranged between the two insulating plates.
When the locomotive is in operation, the roller of the pantograph rolls flexibly on a locomotive line, can pass through smoothly when unsmooth, has small friction and obviously reduced abrasion, and the support rod prevents the two sides from deforming under stress; when the maintenance is changed, only the roller bracket and the insulating plate on one side need to be removed, and the operation is simple.
Preferably, the roller support and the insulating plate are connected through bolts, a plurality of threaded holes are formed in the roller support, and the height of the roller support can be adjusted by replacing the installed threaded holes, so that the roller is normally in line contact with a locomotive.
Preferably, the support rod is provided with a balancing weight, the gravity center of the balancing weight and the gravity center of the roller are on the same vertical line, the roller is kept perpendicular to the locomotive line, and tripping operation caused by the fact that the pantograph is overturned in the running process is prevented.
Compared with the prior art, the invention has the beneficial effects that:
the utility model provides a low frictional resistance electric locomotive pantograph changes sliding friction into rolling, and pantograph and overhead line wearing and tearing obviously reduce, guarantee the safety of electric locomotive in service, reduce the maintenance number of times, practiced thrift the cost, raise the efficiency.
Drawings
FIG. 1 is a schematic diagram of the present invention.
In the figure: 1. an insulating plate; 2. a threaded hole; 3. a drum support; 4. a bearing housing; 5. a drum shaft; 6. a key; 7. a drum; 8. a balancing weight; 9. a support rod.
Detailed Description
Embodiments of the invention are further described below with reference to the accompanying drawings:
as shown in fig. 1, a low frictional resistance electric locomotive pantograph includes cylinder 7, and cylinder 7 both ends symmetry is equipped with drum shaft 5, and drum shaft 5 one end is through the key-type connection cooperation in cylinder 7, and the other end stretches out cylinder 7 cover and is equipped with the bearing, and the bearing is equipped with bearing housing 4 outward, is equipped with cylinder support 3 on the bearing housing 4, and cylinder support 3 is connected with insulation board 1, is equipped with bracing piece 9 between two insulation boards 1.
The roller bracket 3 is connected with the insulating plate 1 through a bolt, and a plurality of threaded holes 2 are formed in the roller bracket 3.
The supporting rod 9 is provided with a balancing weight 8.
When the collector bow runs, the roller 7 of the collector bow rolls flexibly on a locomotive line and can pass smoothly when unsmooth, the friction is small, and the abrasion is obviously reduced; the height of the roller bracket 3 can be adjusted by replacing the installed threaded hole 2, so that the roller 7 is ensured to be in normal line contact with the locomotive; when the maintenance is changed, only the roller bracket 3 and the insulating plate 1 on one side need to be removed, and the operation is simple.
