Abstract
The utility model relates to an eccentric device of demolising that overlaps locating pin of a rolling mill roller that rubs, it includes straight -bar, backstop steel sheet and long -drawn -out hammer, straight -bar one end is equipped with the external screw thread, backstop steel sheet of straight -bar other end welding, long -drawn -out hammer cover is at the straight -bar middle part, the outside of long -drawn -out hammer is the arc. The utility model discloses in twisting the locating pin screw with the straight -bar, with long -drawn -out hammer striking backstop steel sheet, take out the locating pin in eccentric cover, improved the locating pin and removed efficiency.
Description
Technical field
This utility model is related to one kind and rubs root milling train, the dismounting dress of the root roll shaft of the rolling mill eccentric bushing alignment pin that specifically rubs
Put.
Background technology
The root roll shaft of the rolling mill eccentric bushing that rubs is divided into upper and lower two parts, is fixed using alignment pin and bolt.Eccentric bushing alignment pin is adopted
With countersunk head design, it is not easily taken out during dismounting, is currently to pull out tightly using bolt, then slowly tap bolt head upwards with hand hammer,
By taking out positioning pin, efficiency comparison is low.
Content of the invention
This utility model is intended to overcome the defect of prior art, provides a kind of tearing open of root roll shaft of the rolling mill eccentric bushing alignment pin that rubs
Except device, improve alignment pin and remove efficiency.
In order to solve above-mentioned technical problem, this utility model is realized in：
A kind of dismounting device of the root roll shaft of the rolling mill eccentric bushing alignment pin that rubs it is characterised in that：It includes straight-bar, backstop steel plate
With long-drawn-out hammer, described straight-bar one end is provided with external screw thread, and the straight-bar other end welds one block of backstop steel plate, and described long-drawn-out hammer is enclosed within straight-bar
Portion.
The dismounting device of the described root roll shaft of the rolling mill eccentric bushing alignment pin that rubs it is characterised in that：The outside of described long-drawn-out hammer is
Arc.
The beneficial effects of the utility model are：Make a straight-bar with round steel, one is processed into and is joined with eccentric bushing female thread
The external screw thread closing；Make trip hammer using large-diameter circular steel, penetrate in straight-bar, long-drawn-out hammer is outside to do camber, is easy to hand-held；In straight-bar
The other end welds one block of backstop steel plate, as stop block；Finally one layer of paint of brushing carry out antirust.Straight-bar is screwed into alignment pin spiral shell
In stricture of vagina, clash into backstop steel plate with long-drawn-out hammer, alignment pin is taken out in eccentric bushing, improve alignment pin and remove efficiency.
Brief description
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings：
Fig. 1 is structural representation of the present utility model.
Specific embodiment
As shown in Figure 1：A kind of dismounting device of the root roll shaft of the rolling mill eccentric bushing alignment pin that rubs, according to alignment pin female thread chi
Very little, make the straight-bar 2 of a headband screw thread 1, the straight-bar other end welds one block of backstop steel plate 3, centre penetrates long-drawn-out hammer 4, will be straight
Bar is screwed in alignment pin screw thread, clashes into steel plate with long-drawn-out hammer, alignment pin is taken out in eccentric bushing.
