Abstract
The invention relates to a device special for lifting a large motor rotor. The device comprises a lifting board (1) which is arranged in the horizontal direction. An upper row of lifting hole plate holes and a lower row of lifting hole plate holes are formed in the lifting board. The upper row of lifting hole plate holes are main lifting hole plate holes (1) which are distributed in the two sides of the gravity center of the lifting board, wherein at least two main lifting hole plate holes are arranged. The lower row of lifting hole plate holes are multiple auxiliary lifting hole plate holes (3) which are arranged from the board head of the lifting board to the board tail of the lifting board. The length of the lifting board is larger than that of the motor rotor. The main lifting hole plate holes are connected with a main lifting hook (5) through steel wire ropes (4). The invention further discloses a lifting method of the device special for lifting the large motor rotor. Due to the fact that the steel wire ropes are transferred to be connected with the auxiliary lifting plate holes in different positions, the motor rotor can be installed or taken out. A crane can be used for better and stably lifting the motor rotor, safety coefficients in the lifting process are increased, and safety accidents are prevented.
Description
Technical field
The present invention relates to a kind of Large Rotor Special device for lifting and hanging method, it is adaptable to metallurgical machine
The lifting of all types of rotors in tool maintenance of equipment installation process.
Background technology
In recent years, along with expanding economy, the mechanization degree of China is more and more higher, safety work problem
Particularly important.In machinery maintenance installation process, safety problem be shouldn't be careless especially.At present greatly
Still do not have during the lifting operation of type rotor a set of to meet large-size machine (more than 2000w) rotor
Special hoisting fixture.Therefore, during hanging large-scale electric motor rotor, security incident happens occasionally.
Occurred the main cause of security incident, substantially hoisting appliance insecure reliable by analysis or lifting side
Method is improper to be caused.At present, the dismounting to general rotor, utilized before this jack by rotor jack-up,
Rotor is slowly extracted out by pulling jack again, after rotor is completely drawn out, then lift.Due to thousand
Easily occur when jin withstands on jack-up rotor to break away or abrasion, and when lifting, tie up to a place of rotor, difficult
To guarantee the level of rotor, safety coefficient is the highest, careless slightly, and security incident easily occurs.
Summary of the invention
The technical problem to be solved is to provide a kind of Large Rotor Special device for lifting,
It is capable of the steady lifting to electronic rotor.
The technical scheme that the present invention solves the problems referred to above is as follows:
A kind of Large Rotor Special device for lifting, it is characterised in that:
It includes horizontally disposed lifting plate, and described lifting plate offers upper and lower two row's liftings
Orifice plate eye, the hole for hoist orderliness of upper row is main hole for hoist orderliness, is distributed in the both sides of lifting plate center of gravity, main
The quantity at least two of hole for hoist orderliness, the hole for hoist orderliness of lower row is several secondary hole for hoist orderlinesses, institute
Stating secondary hole for hoist orderliness and be aligned to plate tail from the plate head of lifting plate, the length of lifting plate is more than rotor
Length, main hole for hoist orderliness is connected with main suspension hook by steel wire rope.
As preferably, the quantity of described secondary hole for hoist orderliness is 6 to 10.
The hanging method of above-mentioned Large Rotor Special device for lifting, it is characterised in that include following step
Rapid:
A, the top of the rotor that lifting plate is moved to needs dismounting；
B, on the front end axle of rotor, install dummy shaft additional by shaft coupling, respectively in the front end of rotor
The front end connecting steel wire ropes of axle, tail end axle and dummy shaft, and by steel wire penetrating secondary lifting orifice plate accordingly
Eye, is connected dummy shaft with secondary hole for hoist orderliness by steel wire rope, makes the rotor steady shape of holding level
State；
C, take from motor bearing seat when rotor is installed to motor bearing seat or by rotor by needs
When going out, the lifting gently of main loop wheel machine, adjust chain block and all tighten up to steel wire rope, until rotor leans on
Near or depart from motor bearing seat, the most mobile main loop wheel machine, make it connect diverse location by moving change steel rope
Secondary hole for hoist orderliness, it is achieved the installation of rotor or taking-up.
Compared with prior art, the beneficial effects of the present invention is:
Two row hole for hoist orderlinesses of the lifting plate of the present invention are conducive to the loop wheel machine steady lifting to rotor,
It is capable of rotor by the position of mobile lifting steel wire rope and remains level, secondary hole for hoist
Orderliness designs for round, beneficially steel wire rope position and connection lifting plate at rotor two or at three
Fixing, add the safety coefficient of hoisting process, it is therefore prevented that the generation of security incident.
