Technical Field

The invention relates to a pantograph head, in particular to a pantograph head of an overhead line electric locomotive.

Background

The pantograph is a device for acquiring electric energy from a contact net of an underground trolley locomotive and is generally installed at the top of the trolley locomotive. The current is bow-shaped for the common pantograph bow support body of electric locomotive in the pit is installed on the bottom plate parallel with the collector bar, and the support body is bow-shaped moreover, has welded the protruding axle of pipe on the bow-shaped, and the collector bar both sides have with the protruding axle complex hole of pipe, when changing the collector bar, need demolish the bolt that bow-shaped is connected with the bottom plate and the bolt of bow gusset plate can change. The rotating part of the pantograph connected with the convex shaft of the circular tube has no lubricating measure, is in a dry friction state, is not flexible to rotate, and has the phenomenon of 'blocking' due to frictional heat generation. In addition, because the bow-shaped frame is provided with radian, the phenomenon of 'hanging bow' is easy to occur when the bow-shaped frame passes through a turnout and an intersection.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: the utility model provides an overhead line electric locomotive pantograph head, the technical problem that solve is: (1) the rotation part of the pantograph connected with the convex shaft of the circular tube is easy to be blocked due to dry friction; (2) the replacement of the current receiving rod is inconvenient; (3) the bow-shaped frame is easy to have the phenomenon of hanging the bow when passing through the turnout and the cross point.

The utility model provides a trolley locomotive pantograph head, includes powered rod, roller and support body, the support body contains two landing legs, the roller is connected between two landing legs, the powered rod passes through the bearing and installs on the roller.

Further, the support body adopts the back taper structure, the lower extreme of support body is provided with the sleeve, be connected with a plurality of bracing pieces on the support body, one of them one end of bracing piece is provided with the joint.

Further, the top of the frame body is flush with the upper end of the power receiving rod.

Further, the sum of the gaps S1 and S2 between the two ends of the powered rod and the two legs is smaller than the diameter of the overhead line.

Further, the outer side surface of the bearing is flush with the end surface of the power receiving rod.

Further, the roller shaft is connected with the supporting legs of the frame body through bolts.

This use is novel to have following advantage for present electric locomotive pantograph bow:

1. the power receiving rod is sleeved on the roll shaft through the bearing, so that the power receiving rod can be ensured to rotate flexibly and is not easy to be blocked.

2. The electrified rod is connected and fixed on the frame body through the roller shaft with the threaded holes at the two ends of the electrified rod and the bolt, so that the electrified rod can be replaced by detaching the bolt when the electrified rod is replaced and taking out the roller shafts at the two ends of the electrified rod, and the operation is simple, convenient and quick.

3. The support body is the back taper structure, avoids the electric locomotive to appear hanging the bow phenomenon when passing through switch and intersect.

Drawings

Fig. 1 is a schematic structural view of a pantograph head of a trolley locomotive.

The number designations in the figures are: 1 electrified stick, 2 support bodies, 3 joints, 4 sleeves, 5 supporting rods, 6 washers, 7 bolts, 8 bearings and 9 roll shafts.

Detailed Description

The invention is further explained in detail with reference to the drawings and the embodiments as follows:

as shown in fig. 1, the pantograph head of the trolley locomotive comprises a power receiving rod 1, a roll shaft 9 and a frame body 2, wherein the frame body 2 comprises two support legs.

Roller 9 is connected between two landing legs of support body 2 through the mode of dismantling, and the connected mode can be modes such as bolt, screw, bolt connection, articulated, and preferred selection bolted connection in this embodiment the both ends of roller 9 are designed with the internal thread, convenient dismantlement. Roller 9 is the level setting, receive the excellent 1 suit of bearing through two, and two bearings 8 are installed respectively at the both ends of roller 9 on roller 9 is gone up to the powered rod, and the outer terminal surface parallel and level of the outer terminal surface of the powered rod 1 that the outer terminal surface of bearing 8 and correspond. And a gasket 6 is arranged at the joint of the bolt 7 and the frame body 2.

The span between the support legs is determined according to the length of the power receiving rod 1 and the diameter of a trolley wire, and the sum of gaps S1 and S2 between the two ends of the power receiving rod 1 and the support legs is ensured to be smaller than the diameter of the trolley wire.

The shape of support body 2 preferentially adopts the back taper, the top of support body 2 flushes with receiving 1 upper end of excellent.

A plurality of bracing pieces 5 of fixedly connected with on the support body 2 can use connection modes such as welding, guarantees the intensity of support body, 5 one of them bracing piece one end of a plurality of bracing pieces is provided with and connects 3, conveniently connects the lead wire. The lower extreme outside of support body 2 still is provided with sleeve 4, sleeve 4 can use modes such as welding or threaded connection to be connected with the support body, sleeve 4 can be used for installing the insulating rod.

When changing the powered rod 1, only need demolish bolt 7 and packing ring 6, later can take roller 9 out from powered rod 1, change powered rod 1, install roller 9 and bearing 8 in the powered rod 1 after changing, with the bolt with it fix on support body 2 can, this easy operation convenient and fast. Because the bearing 8 is arranged between the power receiving rod 1 and the roller shaft 9, the power receiving rod can flexibly rotate, the dry friction between the power receiving rod and the overhead line is avoided, and the service life of the power receiving rod 1 and the overhead line is prolonged.
