Abstract
The utility model belongs to the field of pantograph for mining electric locomotives and in particular discloses a collector head for a pantograph of a mining electric locomotive. The collector head comprises a current collecting rod, a soleplate parallel to the current collecting rod, and pantograph supports symmetrically connected fixedly at two ends of the soleplate. Inclined struts are symmetrically connected fixedly at the two bottom ends of the pantograph supports; the other ends of the inclined struts are fixedly connected with the pantograph supports at spherical heads fixedly connected at the top ends of the pantograph supports and provided with circular tubular convex shafts; and two ends of the current collecting rod are respectively provided with holes which can be inserted and matched with the circular tubular convex shafts. The collector head is characterized in that L-shaped holes are arranged in the spherical heads and along the axial centerline of the circular tubular convex shafts, the vertical parts of the L-shaped holes face upward, and the horizontal parts of the L-shaped holes run through the circular tubular convex shafts. The original fixed connection between the current collecting rod and the pantograph supports through riveting bolts is changed to be movable sliding connection, so the current collecting rod is easy to overhaul and replace. Meanwhile, due to the lubrication of the lubricating oil between the current collecting rod and the circular tubular convex shafts, the rotational friction is reduced and the collecting rod is flexible to rotate, thus prolonging the service life of the collecting rod.
Description
Technical field

Background technology
The bow of original mining electric locomotive pantograph, comprise be subjected to torch, the base plate parallel, the shelf that symmetry is connected in the base plate two ends with being subjected to torch, shelf two bottoms symmetry again are fixed with diagonal brace, the other end of diagonal brace is captiveed joint with shelf at the spherical head place that has the protruding axle of pipe that the shelf top ends is connected, and is subjected to the torch two ends to offer the hole of pegging graft and cooperating with the protruding axle of pipe respectively.All component in the bow of pantograph all is that employing riveted joint, welding assembly are in aggregates.When pantograph is obtained electric energy from contacting netting twine, rub with contacting netting twine by torch, be subjected to torch wearing and tearing certainly will take place and can not continue to use after long-time the use.Adopt the pantograph collector head of this riveting pin structure, when wherein consumable accessory need be changed by torch, then need cutting riveted joint, weld nugget; More renew part when assembling, rivet again, welding sequence, waste time and energy, had a strong impact on the normal operation of producing.In addition, be subjected to torch and rotation place of shelf bonded assembly, unlubricated, be in dry friction, rotate dumb, the time and occur because of frictional heating " stuck " state.
The utility model content
For overcoming the deficiencies in the prior art part, the purpose of this utility model is to provide a kind of bow of mining electric locomotive pantograph.
For achieving the above object, the technical scheme that the utility model is taked is as follows: a kind of bow of mining electric locomotive pantograph, comprise and be subjected to torch, the base plate parallel with being subjected to torch, symmetry is connected in the shelf at base plate two ends, shelf two bottoms symmetry again are fixed with diagonal brace, the other end of diagonal brace is captiveed joint with shelf at the spherical head place that has the protruding axle of pipe that the shelf top ends is connected, be subjected to the torch two ends to offer the hole of pegging graft and cooperating respectively with the protruding axle of pipe, its improvements are: inner and offer L-shaped hole along the shaft centre line of the protruding axle of pipe at spherical head, and the vertical core in " L " shape hole up, and the lateral aperture in " L " shape hole runs through the protruding axle of pipe.
Reserve certain space for the lubricating oil of giving postorder, the vertical core in " L " shape hole and the outside transition portion between the lateral aperture are designed to the back taper transition.
The vertical core in " L " shape hole is that filler port supplies to add lubricant usefulness, and offers the lateral aperture at least one oil outlet and connection " L " shape hole along the axle side of the protruding axle of pipe.
Preferably, described oil outlet is opened in the lower shaft side of the protruding axle of pipe.
Further, for rationally controlling oil pump capacity, avoid a large amount of wastes of lubricating oil, the lateral aperture section in " L " shape hole between oil outlet and the protruding shaft end of pipe is provided with plug.
Preferably, described plug is the metal plug.
Further,, prevent from that the protruding axle of pipe from skidding off to be subjected to torch and shelf takes place, to be subjected to the disengaging of torch that be parallel to and be subjected to torch or base plate, at least one reinforced plate is connected between two diagonal braces in order to stablize shelf and to be subjected to the relative position of torch.
Preferably, make maintenance or to change contact rod more easy for ease of the installation or removal reinforced plate, between two diagonal braces, adopt the bolt reinforced plate that is connected.
Connect lead for convenience, be fixed with screw in two bottoms of shelf.
Through after improving, of the present utility modelly be subjected to be converted into the mobile lubrication formula by original riveting pin captive joint between torch and the shelf and be connected, make maintenance, change and be subjected to torch more easy.Simultaneously, be subjected to because of the lubricated of lubricating oil arranged, to have reduced pivoting friction between the protruding axle of torch and pipe, rotated flexibly by torch, prolonged the service life that is subjected to torch.
Description of drawings
Accompanying drawing is protruding axle of structural representation of the present utility model and pipe and the part sectional view that is subjected to grafting cooperation place, torch hole, shelf and back plate connections.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in drawings, a kind of bow of mining electric locomotive pantograph, comprise and be subjected to torch 1, the base plate 2 parallel with being subjected to torch 1, in base plate 2 two ends boring 12, with screw at the base plate 2 two ends symmetries shelf 3 that is connected, 3 liang of bottoms of shelf are symmetrically welded with diagonal brace 4 again, also weld a screw 15, screw 15 is used to connect lead, the top ends of shelf 3 is fixed with the spherical head 6 that has the protruding axle 5 of pipe, the axle head of the protruding axle 5 of pipe is processed into frustum, the other end of diagonal brace 4 is in spherical head 6 places and shelf 3 welding, be subjected to torch 1 two ends to offer the taper hole 7 of pegging graft and cooperating respectively with the protruding axle 5 of pipe, inner and offer L-shaped hole at spherical head 6 along the shaft centre line of the protruding axle 5 of pipe, and the vertical core in " L " shape hole is filler port 8, the aperture is up, the lateral aperture in " L " shape hole runs through the protruding axle 5 of pipe, and the outside transition portion between vertical core and the lateral aperture is the back taper transition.An oil outlet 9 is offered in lower shaft side at the protruding axle 5 of pipe.The lateral aperture section in " L " shape hole between oil outlet 9 and the protruding axle of pipe 5 ends is provided with metal plug 10.In order to stablize shelf 3 and the relative position that is subjected to torch 1, be parallel to and be subjected to torch 1 or base plate 2, welded plate ear 13 at first respectively on two diagonal braces 4 bores slotted hole 14 subsequently on plate ear 13, pass slotted hole 14 on the plate ear 13 with screw at last, a reinforced plate 11 is connected between two diagonal braces 4.
