The utility model content
The purpose of this utility model is to provide a kind of repair hoisting device that can the fast assembling-disassembling distributor chute.
The purpose of this utility model is to realize like this, a kind of distributor chute repair hoisting device, comprise the furnace roof small frame, be arranged on platform A and platform B on the described furnace roof small frame, it is characterized in that: also comprise hoisting crane and with described hoisting crane bonded assembly changing device more, described hoisting crane is connected with maintenance beam on being arranged on the furnace roof large platform, and its height is less than the spacing of platform A and platform B and can move and distributor chute is implemented dismounting and install by described more changing device along described maintenance beam.
For dismounting distributor chute fast and accurately, above-mentioned hoisting crane comprises framework, traveling gear and lifting mechanism are set on the described framework, described traveling gear can drive hoisting crane along above-mentioned maintenance beam parallel motion, and described lifting mechanism adopts the lifting rope tool to be connected with above-mentioned more changing device and can control described more changing device fixed point by the changed course pulley and moves up and down.
Changing device enters in the furnace roof small frame distributor chute enforcement dismounting in order to make above-mentioned hoisting crane drive more, above-mentioned changed course pulley is fixed on the changed course suspension centre frame that is arranged on the described framework front end side bar, and the width of described changed course suspension centre frame is less than the opening of the platform B on the furnace roof small frame.
For the hoisting crane smooth running is not interfered with other parts, above-mentioned maintenance beam is two and parallelly and symmetrical passes the both sides that the furnace roof small frame is arranged on the body of heater center, described maintenance beam is provided with track, and described hoisting crane is connected with described track by pulley.
In order to prevent that hoisting crane and furnace roof small frame from touching, above-mentioned maintenance beam is provided with car bumper.
Contact the vibration that produces with other parts in order to reduce hoisting crane, the side bar front and back end on above-mentioned frame both sides is equipped with shock absorber.
During the utility model work, above-mentioned hoisting crane enters in the furnace roof small frame at the driving lower edge of traveling gear above-mentioned maintenance beam parallel motion, above-mentioned lifting mechanism is controlled more the changing device fixed point by the changed course pulley and is moved up and down, thus realize to distributor chute dismounting, install and move.
The utility model has following beneficial effect, the utility model adopts hoisting crane to enter in the furnace roof small frame along maintenance beam parallel motion, controlling changing device more by lifting mechanism moves up and down the dismounting finished distributor chute, installs and move, not only realized distributor chute dismounting fast and accurately, and it is simple in structure, compact, use flexibly, conveniently reliable operation.
