Abstract

The utility model belongs to the technical field of crane current collectors horizontally moving overhead in a plant and in particular relates to a current collector device of a bridge crane. The current collector device comprises a connecting seat, a swing arm, an electric brush support, a conductor electric brush and a binding post, wherein the connecting seat is arranged on a bridge crane body, one end of the swing arm is articulated with the connecting seat, the electric brush support is articulated with the other end of the swing arm, the conductor electric brush is arranged on the electric brush support, and the binding post is connected with the conductor electric brush through a cable. The current collector device is characterized in that the connecting seat is connected with the electric brush support through a spring I, the lower end of the middle part of the swing arm is connected with the electric brush support through a spring II, and electric brush limiting wear protection devices are arranged at the two sides of the conductor electric brush and are connected with the electric brush support. The current collector device is simple in structure and low in cost, does not need power, is easy to install and has remarkable effect after implementation.

Description

Overhead crane current-collector device

Technical field

The utility model belongs to the crane current-collector technical field that moves horizontally in the factory building in the air, relates in particular to a kind of overhead crane current-collector device.

Background technology

Overhead crane is an industrial premises hoisting equipment commonly used; Its power resources are to lean on the current-collector that is connected with the crane that moves and be located at trolley on the supporting frame of factory building both sides and be slidingly connected and realize; Wherein trolley is one group of electric conductor assembly of vertically arranging and be connected with electrical source of power; Current-collector is made up of with the one group of brush assembly of electric that is slidingly connected with one group of electric conductor assembly and the one group of cable that respectively one group of brush assembly of electric is connected with the crane electric control gear on being located at this support the support that is connected with crane; Therefore crane is in operation or lifting process, and the performance quality of brush assembly of electric and trolley sliding contact directly affects the performance index of crane.Find after using a period of time according to the scene, 2000A type overhead crane, the support that is used for installing brush can not satisfy that brush is connected with the trolley Continuous Sliding needs; Brush adopts single pressure point restriction with contacting of trolley, causes the slide block discontinuity, and the conductive slider on the brush is relatively rotated; The result is that a lateral wearing is fast; One lateral wearing is slow, reduces current-collector useful life, influences ordinary production.

Summary of the invention

The purpose of the utility model is to provide a kind of overhead crane current-collector device, guarantees that brush contacts with the effective of trolley, reduces the uneven wear of brush, improves the useful life of brush.

The purpose of the utility model realizes through following technical proposals:

The overhead crane current-collector device of the utility model; It is characterized in that comprising the Connection Block that is located on the overhead crane car body; The swing arm that is hinged of Connection Block therewith of one end, the brush bearing that is hinged of the other end of swing arm therewith, be located on this brush bearing the conductor brush with through the cable binding post that is connected of conductor brush therewith; It is characterized in that described Connection Block is connected with described brush bearing through the spring I; The lower end, middle part of said swing arm is connected with described brush bearing through the spring II, and described conductor brush both sides are provided with brush limiting wear protective device, and this brush limiting wear protective device is connected with described brush bearing.

The advantage of the utility model:

The utility model is finely tuned the stressed of conductor brush through spring, impels conductor brush both sides stressed evenly, and stable operation reduces the concentrated wear of conductor brush, prolongs the useful life of current-collector.And the utility model simple in structure, need not power, with low cost, to be easy to install, to implement the back effect remarkable.
