Description

TECHNICAL FIELD

[0001] The utility model relates to a tooling accessory of continuous casting double rack straightening and leveling machine. BACKGROUND

[0002] Arc continuous casting machine is the main force of steel industry production casting blank, square billet, rectangular billet and round billet generally adopt arc continuous casting machine production, occupy the dominant position, even if it is using straight arc arrangement's continuous casting machine, it is needful to use round arc section transition, still need to straighten the casting blank after arc section. The straightening and leveling machine of square billet and round billet arc continuous casting machine is arranged in the vicinity of horizontal line, and the straightening and leveling machine in the continuous casting production process is particularly important, it not only balances the slide force of casting blank, simultaneously constant casting blank pulling speed, also need it to send the dummy, the most important point is the function of straightening the casting blank. The form of straightening and leveling machine used by different specifications arc continuous casting machine is also different. When the continuous casting machine produces large specification round casting blank, a double rack, upper and lower roller four drive and four oil cylinder lifting control straightening and leveling machine is adopted, and there are 6 sets in total for each flow. Since there are many sub-equipment on each straightening and leveling machine body, the natural arrangement of the cable is also more complicated. After the installation of the straightening and leveling machine, the incoming cable enters the plug-in box in the middle of the double rack through the non-driving side water-cooled steel pipe of the straightening and leveling machine until the top, and then is dispersed to each sub-equipment through plug-in connection.

[0003] The cable installation method of the double rack straightening and leveling machine is special, and the equipment on the straightening and leveling machine body is widely divided, which forces the cable to cross the entire rack. However, the middle of the entire rack is hollow, and the large amount of heat generated by the casting flow during continuous casting will directly affect the plug-in box and the cable located in the hollow part of the double rack. Over time, the cable will be damaged by the heat and short-circuit, which will cause the straightening and leveling machine to malfunction, and the chain effect will cause production accidents. INVENTION CONTENTS

[0004] The utility model solves the technical problem in the prior art, and provides a protective cover for protecting the cable.

[0005] The utility model adopts the technical scheme to solve the above problems: an arc continuous casting machine double rack straightening and leveling machine body cable protective cover is arranged at the middle position of the top of the double rack straightening and leveling machine, that is, the middle blank position of the two racks, and comprises a baffle, a channel steel and a cover plate. The size of the baffle is adapted to the middle blank area of the two racks. The channel steel forms a box body around the baffle. The cover plate is arranged at the top of the box body to open and close the box body. A plurality of perforations are formed on the opposite surfaces of the channel steel for the cable to pass into the box body from the non-driving side of the double rack straightening and leveling machine and then pass out from the other side.

[0006] Preferably, the cover plate is hinged to the channel steel to form a flip cover structure for the box body, so as to open and check the cable condition, and at the same time, the cover plate protects the cable from being damaged by falling debris.

[0007] Preferably, a ceramic fiber heat insulation layer is laid on the baffle. During continuous casting operation, the heat of the casting flow upsurges, and the baffle is impacted by the heat flow from below. In order to protect the cable passing through the middle of the double rack from being scalded, the baffle is provided with a heat insulation layer.

[0008] Preferably, a cross support structure is arranged in the box body to protect the mechanical strength of the box body and avoid serious deformation under the impact of the heat flow for a long time.

[0009] Compared with the prior art, the utility model has the advantages that the cable protection cover is installed at the middle hole position of the top of the double rack stretch leveler, and the size of the protection cover is adapted to the size of the space between the double racks. The cable is directly inserted into the protection cover through the hole after passing through the non-driving side of the stretch leveler, and then is taken out from the other side to enter the plug-in box of the stretch leveler body. In this way, the cable can be effectively protected from being scalded by the heat source from below, and after the cover plate is closed, it can be ensured that the cable will not be hit by the falling debris from above.
