Description
Technical field
The utility model is related to a kind of hot galvanizing line heating furnace roller speed reducer installation tools, belong to metallurgy industry galvanizing
Line heating furnace roller speed reducer installs equipment technical field.
Background technology
The main function of hot galvanizing line heating furnace is that strip is made to be heated to certain temperature in stove, improves the mechanicalness of strip
Can, while making strip tool there are one active surfaces existing for clean oxide-free, and so that strip sealing is entered in zinc pot and carry out
Galvanizing operation.
Hot galvanizing line heating furnace body is generally divided into updraft section, cooling section and soaking zone three parts, wherein heating furnace updraft
Duan Wendu high reaches 1200 degree or so, can cause updraft section replacing furnace roller frequency very high under high temperature environment.The rotation of furnace roller by
Motor drives speed reducer to drive, and when replacing updraft section furnace roller, will will drive the speed reducer of furnace roller rotation from old furnace roller
It is installed to after removing on the new furnace roller of replacement, during installing speed reducer on new furnace roller, since output end of reducer is
Parallel hollow shaft structure, furnace roller installation position are interspersed in output end of reducer hollow shaft, output end of reducer hollow shaft and stove
It is interference fit between roller driving side, in previous installation process, taps speed reducer by sledgehammer, speed reducer is installed to
Position, this percussion speed reducer installation process in, furnace roller certainly will tap direction on stress play, due to installation furnace roller slow down
During machine, bearing block for furnace roller is already affixed to position, and furnace roller is on tapping direction after stress play, the bearing in stove bearing block
Will necessarily be by different degrees of damage, when serious, bearing meeting locking, causes furnace roller not rotate in process of production.Separately
Outside, during hammering speed reducer, the number of hammering is more, more be easy to cause speed reducer oil leak, once speed reducer oil starvation, slows down
Machine internal gear can be damaged greatly, and furnace roller is caused not rotate.Both the above situation can all cause strip to scratch, cause matter
Amount accident influences the loss of hot galvanizing line yield very big.
Utility model content
The utility model aim is to provide a kind of hot galvanizing line heating furnace roller speed reducer installation tool, can steadily effectively
Furnace roller speed reducer is installed on heating furnace roller, solve the problems, such as background technology.
The technical solution of the utility model is：
A kind of hot galvanizing line heating furnace roller speed reducer installation tool, including casing, pipe fitting, feed-through hydraulic are very heavy
Top, nut and full flight screw, full flight screw are fixedly connected with one end of pipe fitting, and the other end of pipe fitting is equipped with interior spiral shell
Line, casing are sleeved on pipe fitting, and feed-through hydraulic jack is through on full flight screw, the piston rod of feed-through hydraulic jack
With casing-contact, thread screw is equipped with nut.
The pipe fitting sets female one end and is threadedly coupled with heating furnace roller.
Casing on the pipe fitting is withstood in the hollow shaft of furnace roller output end of reducer.
The middle part of the pipe fitting along the circumferential direction sets that there are one the boss that protrude outward.
Pipe fitting is set by female one end and stove when heating furnace roller installs speed reducer using the utility model
Roller is threaded, and makes the hollow shaft and casing-contact of furnace roller output end of reducer, rotates the spiral shell on full flight screw
Mother makes feed-through hydraulic jack be fixed on full flight screw until the hydraulic cylinder bottom contact with feed-through hydraulic jack
On, with the stretching of the piston rod of feed-through hydraulic jack, push the casing contacted to move forward, due to cannula tip and stove
Roller output end of reducer hollow shaft contacts, and with the Forward of sleeve position, furnace roller speed reducer position also moves forward, until smoothly pacifying
It is attached to position.
The utility model has the beneficial effects that：Smoothly furnace roller speed reducer can be installed on heating furnace roller, effectively
Ground avoids during installing furnace roller speed reducer, and the bearing caused by hammering furnace roller speed reducer in bearing block is impaired and slows down
Machine oil leak, avoid in process of production because bearing locking and furnace roller speed reducer internal gear damage cause furnace roller do not rotate and
Strip is scratched, strip quality defect is caused.

Specific implementation mode
Below in conjunction with attached drawing, by example, the utility model is described in further detail.
With reference to attached drawing 1-6, a kind of hot galvanizing line heating furnace roller speed reducer installation tool, including casing 2, pipe fitting 3, wearing
Core type hydraulic jack 4, nut 5 and full flight screw 6, full flight screw 6 are fixedly connected with one end of pipe fitting 3, pipe fitting 3
The other end be equipped with internal thread, casing 2 is sleeved on pipe fitting 3, and feed-through hydraulic jack 4 is through on full flight screw 6, punching
The piston rod of formula hydraulic jack 4 is contacted with casing 2, and thread screw 6 is equipped with nut 5.
In the present embodiment：
Casing 2：Stainless steel tube, outer diameter φ 55-65mm, internal diameter φ 47-57mm, long 150-190mm.
