Abstract

The utility model provides an electric bridge crane for a metallurgical cast house, which comprises a bridge (1), a trolley (2), a crane traveling mechanism (3) and is characterized in that a draping beam (10) is welded under a box girder (5) of one side of the frame. A bearing pedestal scaffold (6) is welded at the outside of the box girder (5) and the draping beam (10). Through the upper and lower bearing pedestal scaffold (8) and (12) connecting with the bearing pedestal scaffold (6) and a connecting bolt (7), a cantilever crane (4) which with a driving mechanism and can round the center of the bearing (17) is installed. The electric bridge crane can be driven to the place close to a blast furnace and realize lifting load at a space pipeline, a tap hole machine, a dust-cleaning equipment, an anterior part of a sow channel and a tuyere platform and so on, thereby meeting the requirements of allocation and production of the cast house.

Description

A kind of electric overhead travelling crane
The utility model relates to the weight-hauling equipment that metallurgical cast house is used, and particularly relates to a kind of electric overhead travelling crane.
The existing electric overhead travelling crane that is used for metallurgical cast house mainly is a twin beam overhead bridge crane, and this hoisting crane mainly is made up of crane span structure, dolly, crane travel mechanism, hoisting crane control mechanism.Crane span structure is made up of two box girders, two box-shaped end carriages and walking on stage of girder both sides.Lay track on the upper cover plate of girder, be used for carriage walking, one sidles the operating unit that hoisting crane is installed on the platform, and opposite side is walked on stage dolly lashed cable conduction is installed.Dolly is made up of vehicle frame, lift system, operating unit.Crane travel mechanism is made up of motor, drg, reductor, coupler, wheel.The hoisting crane control mechanism is made up of brake activation device, total power switch, safety switch, guard box etc.This electric overhead travelling crane can by dolly realize along the back and forth movement of girder and dolly lifted weight up-and-down movement, can go up the crane travel mechanism of installing by walking on stage and realize the vertical back and forth movement of crane span structure along big Car Track.But this crane in bridge type is owing to be subjected to restrictions such as space pipeline, blast furnace iron notch drill, dusting equipment, building, can not reach place near blast furnace, locate to form certain lifting job dead angle at cast house tap drain front portion and tuyere platform etc., scope of work is restricted, and makes troubles to work.
It is more extensive that the purpose of this utility model provides a kind of scope of work, can realize that the anterior and tuyere platform of cast house tap drain etc. locates lifting and hang thing, satisfies the electric overhead travelling crane of cast house handling production needs.
The utility model is to realize like this, providing a kind of comprises by two girders, the crane span structure that two butt beams are welded, by vehicle frame, operating unit, the dolly that parts such as lift system are formed, by motor, drg, reductor, coupler, the crane travel mechanism that wheel is formed, it is characterized in that below crane span structure one side box girder, being welded with the beam that dangles, box girder, the dangle beam outside is welded with bearing bracket, by with bearing bracket, the metal (upper seat that tie bolt is threaded is installed a cover tape drive mechanism, can be around the boom crane of bearing center rotation, the big gear wheel engagement of captiveing joint on the miniature gears of the driver train of this boom crane and the cantilever beam, cantilever beam, the opposite position that dangles on the beam is installed a cover rotary limit device.
The utility model is owing to installed boom crane on Overhead Crane Bridge, can reach place near blast furnace, locate to form certain lifting job scope at space pipeline, iron notch drill, dusting equipment, cast house tap drain front portion and tuyere platform etc., can realize that the anterior and tuyere platform of cast house tap drain etc. locates lifting and hang thing, satisfy the needs of cast house handling production.
