Description

The electric locomotive collector bow

Affiliated technical field

The utility model relates to the power transmission of the electric locomotive of using in a kind of mine transportation means parts, the especially tunnel, mine, belongs to the mechanical ﹠ electrical technology field.

Background technology

The orbital motor car that operation is used in tunnel, mine or driving surface, its required drive are to be located at the direct current (DC) that the bare cable (being commonly called as the locomotive line) of track top provides by parallel shelf.The collector bow (also claiming to inhale electrical equipment) that is arranged on the electric locomotive utilizes its cylinder under the pulling force of bidirectional spring, the locomotive line is done the horizontal gliding motility identical with the electric locomotive travel direction relatively, collector bow is supplied with electric locomotive by cylinder with the electric energy that provides on the motor fare, and it is orbited.The shortcoming that existing collector bow exists is, cylinder is because long-time same azimuth rotation, and the locomotive line is to the serious wear in the middle of the cylinder, produce depression in the middle of making cylinder, even make its fracture, it is scrapped in the short period of time, need the frequent cylinder of changing, cause operating cost higher; They are two years old, cylinder is done gliding motility with respect to the locomotive line, its locomotive produces level left and right sides force of inertia, depending merely on bidirectional spring can not eliminate effectively, thereby the locomotive line is caused wearing and tearing, damages, moreover bidirectional spring excessively strains, its reliable in action is significantly reduced, often need manually utilize the collector bow hauling rope to replenish elastic force, cause operating efficiency low, the repair and maintenance amount is big.

The utility model content

In order to overcome existing electric locomotive collector bow complex operation, deficiency that operating efficiency is low, the utility model provides a kind of simple to operate, precise control, highly sensitive, long service life, reliable electric locomotive collector bow.

The technical scheme that its technical matters that solves the utility model adopts is: the electric locomotive collector bow, comprise cylinder 1, drum shaft 2, rolling stand 3, bow support 4, carbon brush 5, carbon brush support 6 and counterweight 7, also be provided with roller bearings 9, bow bracket bearing 10, cylinder 1 is formed by segmentation cylinder serial connection, its two ends are provided with locking pin 8, drum shaft 2 two ends are connected by roller bearings 9 with rolling stand 3, rolling stand 3 is provided with driving device 12, bow support 4 is provided with bow axle 11, be connected by bending bracket bearing 10 between bow axle 11 and the bow support 4, counterweight 7 precipices hang on the bow axle 11, and carbon brush support 6 is fixed on the rolling stand 3.

The beneficial effects of the utility model are, because cylinder is done rolling movement with respect to the locomotive line, the wearing and tearing of cylinder and locomotive line are obviously alleviated, make operating cost reduce greatly, improve operating efficiency, reduced maintenance rate, prolonged the service life of cylinder and locomotive line; And simple to operate, precise control, highly sensitive, reliable.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is the left view of Fig. 1.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

The electric locomotive collector bow, comprise cylinder 1, drum shaft 2, rolling stand 3, bow support 4, carbon brush 5, carbon brush support 6 and counterweight 7, also be provided with roller bearings 9, bow bracket bearing 10, cylinder 1 is formed by 4 segmentation cylinder serial connections, cylinder is subject to worn-down to be had only with the motor fare and contacts interlude, and two ends cylinder section relative wear is less, with the two exchange, thereby improves service life.Its two ends are provided with locking pin 8, and effect is that separate cylinder is produced fastening force, makes its one-tenth as a whole, together rotates with drum shaft.Be connected by roller bearings 9 between drum shaft 2 two ends and the rolling stand 3, rolling stand 3 is provided with gear cluster 12, by the transmission of sensor and Single-chip Controlling gear, adjusts the height of rolling stand 3 with this.Bow support 4 is provided with bow axle 11, and is connected by bow bracket bearing 10 between the bow support 4, and counterweight 7 precipices hang over bends on spools 11, and carbon brush support 6 is fixed on the rolling stand 3.

An insulation of drum shaft 2 outer rims parcel material, purpose is to produce the ground insulation effect, avoids motor fare ground short circuit, and the accident of explaining takes place to jump.

The contact end face of carbon brush 5 cooperates with the cylindrical shape of cylinder 1, makes to be subjected to electricity reliable.

9 rollings action of roller bearings avoid cylinder 1 to do the line contact with motor fare 14, and the guarantee point contact prolongs its life-span.

Rolling stand 3 is adjusted its height by two sleeve gear groups 12 except that playing back-up roller 1 effect.Height is spent low, and cylinder 1 can't be contacted with locomotive line 14, can not be subjected to; Too highly will cause the cylinder undue wear, influence its life-span.Too high and cross when low, do corresponding transmission by sensor by Single-chip Controlling gear cluster 12 and reach the purpose of adjusting height.

The effect of carbon brush support 6 is by it carbon brush 5 to be installed, and the direct supply on the cylinder 1 is imported the automatically controlled part of electric locomotive, makes its operation.

Bow bracket bearing 10 plays a part to roll and adjust height, actual state is that restriction and other many reasons owing to the mine geographical conditions make the locomotive line be difficult to remain on the same horizon, rail is laid and is difficult to realize same horizontal surface in addition, causes locomotive line 14 to be uneven; Moreover train starting, the inertia that moves, produces when stopping will to drive collector bow and do the certain amplitude swing, and its bow bracket bearing 10 can be eliminated the stress of the amplitude of oscillation.

Counterweight 7 is hung over above the bow axle 11 by steel cable 13 precipices, its center of gravity all the time with the center of gravity of cylinder 1 on same vertical line, purpose is keep cylinder 1 and locomotive line 14 vertical, prevents to take place collector bow and overturn in operational process, causes the ground connection jumping to explain accident.Its counterweight is divided into the separate unit that quantity does not wait, and is convenient to increase and decrease by actual needs.

Driving device 12 is two sleeve gear groups, is located at the bottom of rolling stand 3, when cylinder 1 contacts mal with locomotive line 14, by sensor and Single-chip Controlling gear cluster 12, adjusts the height of rolling stand 3, and cylinder 1 is contacted normally with locomotive line 14.

In conjunction with the accompanying drawings the specific embodiment of the present utility model has been carried out exemplary description above, obviously the utility model is not limited thereto, and the various remodeling that carry out in the utility model scope all do not exceed protection domain of the present utility model.
