Description

Current collector

Technical Field

The utility model relates to an engineering equipment field, in particular to current collector.

Background

The mobile equipment (mainly cranes, traveling cranes, etc.) needs to be changed in position continuously due to movement, and at each different position, the mobile equipment needs to be powered at any time, otherwise, the mobile equipment cannot be moved continuously. At this time, the trolley line is produced, a plurality of conductors are laid in parallel along the running track of the mobile equipment, the power supply is switched on, and the current collector capable of taking electricity from the conductors is arranged on the mobile equipment, so that when the equipment moves, the current collector synchronously runs along with the equipment, and the power supply is taken from the conductors at any time and is supplied to the equipment, so that the equipment can continue to move. Current collectors used in conjunction with trolley lines are elements that transfer current from the trolley line conductive slots to the vehicle. The carbon brush box of the current collector can rub against the shell of the sliding contact line in the sliding process of the sliding contact line, and further the service life of the sliding contact line can be influenced. In the prior art, for example, patent CN106848794A discloses a relay, which has guide wheels at two ends of the relay, but because the guide wheels are only disposed at the upper and lower sides of the carbon brush box, the relay still rubs against the sliding contact wire slot during the sliding process.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve the frictional problem of current collector and sliding contact wire casing among the prior art, provide a current collector.

The purpose of the utility model is realized through the following technical scheme:

a current collector comprises a carbon brush box main body, a mounting body and an indicator light assembly; the carbon brush box main body is connected with the indicating lamp component through the mounting body; the two ends of the carbon brush box main body are provided with guide wheel sets, and the guide wheel sets surround the carbon brush box main body.

The current collector is mainly applied to connecting a trolley line and a lifting device. The carbon brush box main body and the mounting body are embedded into a channel formed in the sliding contact line. The carbon brush box main body is provided with carbon brushes, and the number of the carbon brushes is the same as that of the conductive grooves in the sliding contact line. The plastic housing of the trolley wire may be scratched when the brush box body slides within the channel of the trolley wire. The general carbon brush box main part is the cuboid form, all is provided with the guide pulley group at the both ends of carbon brush box main part to the guide pulley group sets up around carbon brush box main part. So set up, the slip in-process of carbon brush box main part just can not take place the friction with wiping line groove casing to extend the life of wiping line and current collector.

Preferably, the guide wheel group includes four guide wheel groups respectively disposed on four sides of the carbon brush box main body. As above, the carbon brush box main body is set to be rectangular, and the pulley blocks are arranged on four sides of the carbon brush box main body, so that friction between the current collector and the sliding contact line shell can be effectively prevented, the smoothness of the current collector sliding in the sliding contact line is increased, and the abrasion and the service life of the current collector are also prolonged.

Preferably, the carbon brush box main body is provided with a groove, and a clamping hole is formed in the groove; the guide wheel set comprises a pulley and a bearing; the two ends of the bearing are clamped in the clamping holes.

Preferably, when the bearing is clamped in the clamping hole, the pulley protrudes out of the groove.

Preferably, one of the guide pulley sets comprises two pulleys.

One guide wheel set is set to be two sliding contacts, and when the device is used, the pulley is in contact with the sliding contact line shell, and the current collector slides more smoothly.

Compared with the prior art, the utility model discloses following technological effect has:

the utility model provides a current collector sets up the assembly pulley at the both ends of carbon brush box main part to the assembly pulley sets up around carbon brush box main part, and a plurality of assembly pulleys center on carbon brush box main part a week. The friction between the carbon brush box main body and the sliding contact line shell is effectively reduced, and the service life of the current collector and the sliding contact line is prolonged.

Detailed Description

The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

As shown in fig. 1 to 3, a current collector includes a carbon brush case main body 1, a mounting body 2, and an indicator lamp assembly 3; the carbon brush box main body 1 is connected with the indicating lamp component 3 through the mounting body 2; the both ends of carbon brush box main part 1 are provided with guide pulley group 4, guide pulley group 4 centers on carbon brush box main part 1 sets up.

The carbon brush box main body 1 is rectangular, and the guide wheel sets 4 include four and are respectively arranged on four sides of the carbon brush box main body 1.

The carbon brush box main body 1 is provided with a groove 11, and a clamping hole 12 is formed in the groove 11; the guide wheel set 4 comprises a pulley 41 and a bearing 42; the two ends of the bearing 42 are clamped into the clamping holes 12.

When the bearing 42 is clamped in the clamping hole, the pulley 41 protrudes out of the groove 11. I.e. the surface of the pulley 41 is higher than the upper edge of the groove 11.

One of the guide pulley sets comprises two pulleys 41.
