[Industrial applications]

 The present invention relates to an improvement of a chock placing table in a chock attaching / detaching device for rolling rolls, and more specifically, a chock placing table capable of accommodating various sizes of roll chocks with an extremely simple configuration for positioning and holding the chock placing table. It concerns the provision of a table.

[0002]

[Prior art]

 For example, as can be seen in FIGS. 1 and 2 of the embodiment drawings, the roll chock 90 (bearing housing frame) of the rolling backup roll 80 is extremely large, and the weight thereof is about 15 TON to 20 TON (backup). The attachment / detachment of the roll chock 90 to / from the roll neck 85 of the roll 80 has been carried out safely and smoothly by using the air bearing 58 as shown in Japanese Patent Publication No. 53-11271. At the beginning of the conventional development of the roll chock attachment / detachment device, the number of types of roll chock to be implemented using the same roll chock attachment / detachment device was relatively small, and it can be said that it was somewhat limited. However, as the useful and effective aspect of the roll chock attachment / detachment device was subsequently recognized, its application to a wide variety of large-sized rolls became common, leading to the intensive attachment / detachment work by the roll chock recombination center. Therefore, in order to cope with these various types of roll chock sizes and shapes, a so-called tandem type chock mounting table 150 that expands and contracts in the left and right direction along the roll axis is applied as shown in the schematic diagram of FIG. 13 of the conventional example. For example, while we have been dealing with the form of the embodiment shown in (1) and (2) of FIG. 14, this is a roll chock of various sizes and morphologies that cannot be handled by one set 151. Therefore, it has been necessary to prepare a plurality of sets of daitan set 151. Therefore, it is very difficult for the chok replacement worker to select the applicable dai set 151 or the application site. It is extremely complicated and annoying, and the design and manufacture of the new platform set 151 for the new roll chock size has been a difficult and serious problem.

In addition, the roll chock 90, which has an extremely large weight, must be positioned on the chock mounting table and securely held without inserting the roll chock 90 into the roll neck 85 or from the roll neck 85. The movement of the chock trolley 50 plays a major role in the withdrawal and removal of the roll chock 90, and the positioning and holding of the roll chock 90 for this purpose is an indispensable condition for safe, reliable, and smooth attachment / detachment work, and this is ignored. I couldn't do that.

[0004]

[Problems to be solved by the device]

 In view of the above-mentioned circumstances, the present invention aims to provide a chock mounting table that can be used for various sizes of the roll chock 90 reliably and easily with a simple mechanism, and at a low cost. Based on the careful examination and trial accumulation by the researchers, the achievement was achieved.

[0005]

[Means for Solving the Problems]

 The present invention has dealt with by applying the following means in order to solve the above-mentioned problems. In other words, as a mechanism to properly position and hold various sizes of roll chocks with a simple configuration, the upper surfaces of the left and right traverse tables that expand and contract in the lateral direction with respect to the roll axis on a lifting table with a certain area are symmetrical. Two positioning right-angled pieces are provided at each position, and the fixed positioning right-angled pieces on the far side in the roll axis direction are fixed to the respective traverse tables, and the movable positioning right-angled pieces on the front side are movable in the roll axis direction. It is constructed by applying one screw shaft and a screw nut, each of which is engraved with a reverse screw, and the screw shaft is equipped with a gear that is attached to the output shaft of one air motor provided in the center of the side surface in front of the lifting table and the gear. Sprockets that have gears of the same diameter and the same number that mesh with the gears and that are respectively attached to both gear shafts and rotate in opposite directions (have a smaller diameter than the gears) The left and right roller chains that connect a plurality of idle sprockets arranged at appropriate positions and the sprocket that is pivotally mounted on the screw shaft are provided, and the screws rotate in opposite directions based on the drive of the air motor. -The right and left moving positioning right and left pieces on the left and right traverse tables are moved by the same amount in the front-rear direction by the shafts, and each screw shaft flexibly and appropriately responds to the expansion and contraction of the traverse table by the roller chain and sprockets. It was done.

[0006]

[Function of the device]

 The operation of the "chock mounting table of the roll chock attachment / detachment device" (hereinafter simply referred to as the present chock mounting table) of the present invention will be described with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, the chock mounting table 1 is provided on the lifting table 10 which is lifted and lowered by the lift 55 of the chock carrier 50 of the roll chock attachment / detachment device 70, and is mounted on the roll mounting table 60. The roll chocks 90 mounted on the roll necks 85 of the rolls 80 are positioned immediately below the roll chocks 90 by the moving device 53 of the chock carriage 50, and the explanation will be started.

First, the traverse table 20 is expanded / contracted by a separately provided operation panel (not shown), and the roll chock width line of the fixed positioning right angle piece 21 and the moving positioning right angle piece 22 is added to the width of the roll chock 90 plus about 5 to 5. Adjust to 10 mm. At this time, as can be seen clearly in FIGS. 8 and 9, the sprocket 33, 33 axially attached to both screw shafts 31, 31 has a roller chain 38, 38 that is stopped as a rack, and the sprocket 33 has a pinion relationship. The sprocket 33 rotates by an amount corresponding to the moving amount of the traverse table 20, and accordingly, the movable positioning right-angled piece 22 slightly moves. However, this movement is a movement in a state where the roll chock 90 is not placed, and no particular problem occurs. In the relationship between the sprocket 33 and the roller chain 38, the sprocket 33 is moved and positioned by rotating the screw shaft 31 only by the screw shaft 31.The right-angled piece 22 is slightly moved, but the air motor that is the driving force of the roller chain 38 is used. 35 has a large reduction ratio, and it is difficult to rotate the air motor 35 by moving the roller chain 38.The so-called air motor 35 serves as a brake, and the screw shaft 31 is The traverse table 20 can be easily expanded and contracted by being driven. One of the major points of the present invention as a vertical and horizontal axis adjusting device in which the endless drive roller chain 38 is arranged on the movable transverse table 20 is that the mechanism is used. It's not too much to say.

Now, when the roll chock width direction is adjustable, the air motor 35 is driven by the operation panel to drive the moving positioning right-angle piece 22 on the traverse table 20 and the roll chock 90 on the bottom of the roll chock 90 as shown in FIGS. 8 and 9. Adjust to axial distance. At this time, the traverse table 20 is immovable because it is positioned by the screw shaft 31, so that the screw shaft 31 is rotated by the rotation of the sprocket 33 based on the roller chain 38, and the position is adjusted. The left and right screw shafts 31 and 31 rotate in opposite directions to each other, but because of this, reverse screws are engraved, and they move in parallel with the roll axis direction and in the same distance in synchronization. . The fixed positioning right-angled piece 21 is adjusted by the moving device 53 that moves the two chock carriages 50, 50, as described above.

Thus, as can be seen from FIG. 1 and FIG. 2, the mounting position of the main chock mounting table 1 with respect to the bottom of the roll chock 90 is adjusted, and the lifting lift 55 of the chock carriage 50 is lifted to raise the roll chock 90 on the main chock mounting table 1. The weight of is transferred and placed. At this time, it goes without saying that the holding of the roll chock 90 is extremely soft according to the function of the air bearing 58 of the chock truck 50. After that, the chock dolly 50 is moved outward by the moving device 53, and the roll chock 90 is removed from the roll neck 85.At this time, the fixed position right-angled piece 21 works effectively. is there. The insertion of the new roll chock 90 into the roll neck 85 is generally performed in the reverse order, and at this time, the movable positioning right-angled piece 22 works effectively.
