Description

[Detailed Description of the Invention] This invention relates to a support frame for a spindle coupling when a rolling mill roll and a spindle for rolling steel materials are connected and assembled.

The purpose is to propose a support frame for a spindle coupling that facilitates the work of connecting a roll and a spindle, reduces work time and personnel, and improves safety.

Conventionally, as shown in FIG. 1, the middle part of the spindle 2 is supported by a stand-type spindle coupling support frame 1. Roll 3 was being replaced and connected.

In this method, the coupling 4 on the spindle head is lowered, and in order to fit and connect the ends of the rolls, the coupling is lifted using a lever using a crowbar or the like in the case of a small model, or with a hoist or the like in the case of a large model. I needed to lift it.

In addition, the spindle part was narrow and the working conditions were not good, which required a large number of workers and a lot of time, and the safety was low.

This idea was made by focusing on the above-mentioned problems.

This will be explained below with reference to the illustrated embodiments. In FIGS. 2 and 3, two parallel supports 5 are formed on both sides of the head coupling 4 of two upper and lower spindles 2 that protrude in the direction of the rolling rolls 3 from the drive part of the rolling mill. Two standing pillars 6 are standing facing each other.

Each of these two upright columns 6 has two upper and lower coupling support claws 7 facing each other, and the base end is connected to the pin 8.
It is pivotally mounted between the book supports 5 so as to be rotatable in a vertical plane.

Furthermore, the vertical column 6 shown in FIGS. 5 and 6 is provided with a wedge receiver 9 below the support claw I, and a wedge 10 is interposed between it and the upper support claw 7.

This wedge 10 is perpendicular to the support claw I, supports the support claw at a position closer to the tip than the pin 8, and has a long hole 1 extending in the longitudinal direction of the wedge 10.
1, and in this elongated hole 11 there is a wedge receiving rod 1 fixed to the vertical pillar 6.
2 passes through, and the wedge 10 spans the width of the elongated hole 11.
It is movable on the wedge support 9.

The lower part of the wedge 10 resting on the wedge holder 9 is flat, and the upper part is sloped. As the wedge 10 moves back and forth, the supporting claws I resting on the wedge 10 are separated into two parts with the pin 8 at the center. It has a structure that can freely rotate in a vertical plane between the supporting columns 5.

With the above structure, by pushing the wedge 10 deeply, the support claw 7 protrudes between the two upright posts 6, and the coupling 4 is pushed in from both sides by the two support claws I facing each other in a pair. can be supported.

Conversely, if the wedge 10 is pulled out when the coupling 4 is not supported, the support claw 1 support position of the wedge 10 is lowered and the fourth
As shown in the figure, the support claw 7 can be tilted downward between the two parallel supports 5 by rotating around the bin 8.

Further, since the height of the tip of the support claw 7 can be continuously adjusted depending on the degree to which the wedge 10 is pushed in, it is possible to support the coupling 4 at a height that matches its dimensions.

The idea is as described above.

This spindle coupling support frame is mounted on two vertical columns facing each other on both sides of the spindle coupling.
A pair of opposing support claws are rotatably mounted in a vertical plane, and these support claws are rotated by a wedge, protrude between the two upright columns, support the coupling from both sides, and provide support. When not in use, it can be tilted downward.

Also, the exact height can be adjusted to match the coupling dimensions.

As a result, unlike conventional support frames, there is no need to support the spindle and raise the coupling that has fallen downward, and the coupling can be supported at an accurate height position simply by moving the wedge, making the connection work easier. This reduces the number of workers and time required, and is highly safe.

For example, the efficiency can be improved from 3 people x 3 minutes/machine to connect the coupling to the hanging roll using a hoist, to 1 person x 1 minute/machine.

Furthermore, since the support claws can be tilted downward when not supported, there is an advantage that the work space of the spindle section is widened and work efficiency is improved.
