When the roller of the vertical rolling mill is replaced, a special lifting appliance is needed to lift the roller, and whether the design of the special lifting appliance is reasonable or not is related to whether the roller replacement operation can be safely, conveniently and quickly performed or not.
SUMMERY OF THE UTILITY MODEL
In view of the above, the present invention is directed to solve the above-mentioned shortcomings in the background art, and therefore, the present invention provides a 550-type roll changing device for a high-speed wire rod vertical rolling mill, which has a simple structure, is safe and reliable, and can realize safe, convenient and fast roll changing operation.
In order to achieve the purpose, the utility model provides the following technical scheme:
the utility model provides a high-speed wire rod edger 550 type roll-changing device, includes round pin axle and hoist, the hoist including set up in the ear of the lifting spindle both sides of high-speed wire rod edger 550 type, the top of ear is provided with the hole for hoist, the round pin axle runs through in proper order and is located the left ear of lifting spindle the lifting spindle with be located the ear on lifting spindle right side, the one end of round pin axle is provided with the handle, the anticreep hole has been seted up to the other end of round pin axle, the downthehole pegging graft of anticreep has the little round pin axle.
Compared with the prior art, the utility model has the following beneficial effects:
1. the 550-type roll changing device of the high-speed wire rod vertical rolling mill provided by the utility model is simple in structure, safe and reliable, and can realize safe, convenient and quick roll changing operation.
2. The 550-type roll changing device of the high-speed wire rod vertical rolling mill provided by the utility model has direct economic benefits, and specifically comprises the following steps:
benefit description: the original replacement of 550 types of rolls takes 1 hour and 10 minutes, the use of a 550 type roll replacement hanger of a high-speed wire rod vertical rolling mill only takes 45 minutes, and the replacement of the 550 types of rolls of the rough rolling mill is calculated according to 60 times per year, wherein 60 times per year (the number of the rough rolling rolls replaced per year) is multiplied by 30 minutes per time (time is saved each time) and multiplied by 1.5 tons per minute (yield per minute) and multiplied by 220 yuan per ton (steel benefit per ton) is 60 ten thousand yuan.

FIG. 1 is a schematic structural view of the present invention;
in the figure, 1, an ear, 2, a pin shaft and 3, a lifting hole.
Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings of the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model.
As shown in fig. 1, the utility model provides a 550-type roll changing device of a high-speed wire rod vertical rolling mill, which comprises a pin shaft 2 and a lifting appliance, wherein the lifting appliance comprises lugs 1 arranged on two sides of a lifting shaft of the 550-type high-speed wire rod vertical rolling mill, a lifting hole 3 is formed in the top end of each lug 1, the pin shaft 2 sequentially penetrates through the lug 1 on the left side of the lifting shaft, the lifting shaft and the lug 1 on the right side of the lifting shaft, a handle is arranged at one end of the pin shaft 2, an anti-dropping hole is formed in the other end of the pin shaft 2, and a small pin shaft is inserted into the anti-dropping hole.
In the structure of the utility model, a lifting shaft and a small pin shaft are not shown in fig. 1, the Morgan fifth-generation high-speed wire rod vertical mill rough rolling is a roller with the general working outer diameter of 550m according to the effective working outer diameter of the roller, and the main difference is that the shape and the size are different according to the difference of supplied blanks, but the structure forms are the same. The upper part of the vertical rolling mill roller is provided with a lifting shaft, and the lifting shaft is provided with a round hole.
The design of the utility model mainly considers safety and convenience and practicability.
In the utility model, the pin shaft 2 is inserted into the lifting shaft and the lifting appliance body and mainly plays a role of lifting a roller, so that the outer diameter of the pin shaft is as close as possible to the inner diameter of a circular hole of the lifting shaft, and the clearance is generally 1-2 mm.
One side of the pin shaft 2 is provided with an anti-drop hole, and a small pin shaft is inserted. And the other side is provided with a handle, so that an operator can conveniently insert and pull out the plug-in connector.
The lugs on the two sides of the lifting appliance play a role in supporting the pin shaft 2, the gap between the two lugs 1 is close to the outer diameter of the lifting shaft, the gap is too large, the roller is deviated to one side, the upper bearing seat and the lower bearing seat are not vertical, and the lower bearing seat is not easy to be installed in the memorial archway. The clearance is too small, the centering performance of the hanger body and the circular hole of the lifting shaft is not easy to align, and the clearance is generally selected to be 8-10 mm.
The upper end (the top of the two ears) of the hanger is provided with a hoisting hole 3 for installing a steel wire rope, and the hanger body is connected with the hook head of the crane through the steel wire rope to realize normal hoisting.
In the utility model, the hoisting holes 3 arranged at the upper ends (the top ends of the two lugs) of the lifting appliance can be connected through bolts or can be arranged in a welding mode. This is not particularly limited.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
