The high-speed wire pre-finishing rolling area belongs to a high-speed area, so the service cycle of the equipment is relatively short, the service cycle of the roller box is shorter, and the flat roller box is in a heavy-load state for a long time and has larger rolling force, so the replacement is more frequent. Our equipment belongs to a flat rolling non-torque rolling mill, so that the roller box is particularly difficult to disassemble if the lifting angle is not proper when the roller box is replaced, and the roller box is more difficult to assemble.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a dismantle hoist of finish rolling roller case in advance to in the focus of finding the roller case, can make the roller case be in the horizontally state when hoisting the roller case.
In order to solve the technical problem, the utility model adopts the following technical scheme:
the utility model provides a dismantle hoist of finish rolling roller case in advance, includes the hoist body, the hoist body includes upper portion section, interlude and lower part section, wherein the interlude includes the vertical section of lower extreme and the segmental arc of upper end, the lower extreme of vertical section is connected the lower part section, the upper end of segmental arc is connected the upper portion section, upper portion section and lower part section are the diaphragm parallel with the horizontal plane, be provided with at least three drilling side by side on the both ends of upper portion section respectively, one of them be provided with rings in the drilling, be provided with the through-hole on the both ends of lower part section.
Further, the middle section is welded and fixed with the upper section and the lower section respectively.
Further, the lifting ring is an M24 lifting ring.
Furthermore, the lifting appliance body is formed by welding steel plates with the thicknesses of 20mm and 50mm, wherein the lower section and the middle section are made of steel plates with the thicknesses of 20mm, and the upper section is made of steel plates with the thicknesses of 50 mm.
Furthermore, a screw rod is fixed at the lower end of the hanging ring, and the screw rod penetrates through the drilled hole and is fixed by a nut or is assembled and fixed with the drilled hole through threads.
Further, the interlude is including two sets of connecting pieces that the symmetry set up, and is connected with the reinforcement between two sets of connecting pieces.
Compared with the prior art, the utility model discloses a beneficial technological effect:
during working, the lifting appliance and the screw holes on the side surfaces of the roller box panel are fixed through screws, and then the roller box body can be in a horizontal state by using a crown block to lift two lifting rings of the lifting appliance, so that the roller box can be smoothly disassembled or assembled, the working efficiency is effectively improved, the labor intensity is reduced, and the safety factor in working is improved.
Drawings
The present invention will be further explained with reference to the following description of the drawings.
Fig. 1 is a schematic structural view of the lifting appliance for disassembling the pre-finishing roll box of the present invention;
description of reference numerals: 1-hanger body, 2-rings and 3-through holes.
Detailed Description
As shown in fig. 1, a dismantle hoist of finish roll case in advance, includes hoist body 1, hoist body 1 includes upper portion section, interlude and lower part section, wherein the interlude includes the vertical section of lower extreme and the segmental arc of upper end, the lower extreme of vertical section is connected the lower part section, the upper end of segmental arc is connected the upper portion section, upper portion section and lower part section are the diaphragm parallel with the horizontal plane, be provided with 2 drilling side by side respectively on the both ends of upper portion section, one of them be provided with rings in the drilling, be provided with through-hole 3 on the both ends of lower part section.
The middle section is welded and fixed with the upper section and the lower section respectively. The lifting ring is an M24 lifting ring. The lifting appliance body 1 is formed by welding steel plates with the thicknesses of 20mm and 50mm, wherein the lower section and the middle section are made of steel plates with the thicknesses of 20mm, and the upper section is made of steel plates with the thicknesses of 50 mm. And a screw rod is fixed at the lower end of the hanging ring 2, penetrates through the drilled hole and is fixed by a nut or is assembled and fixed with the drilled hole through threads. The interlude is connected with the reinforcement including two sets of connecting pieces that the symmetry set up, and between two sets of connecting pieces.
During working, the lifting appliance and the screw holes on the side surfaces of the roller box panel are fixed through screws, and then the roller box body can be in a horizontal state by using a crown block to lift two lifting rings of the lifting appliance, so that the roller box can be smoothly disassembled or assembled. The screw hole of the screwing hanging ring is tapped into M24, and three M24 screw holes are made in each end of the body side by side so as to adjust the position of the hanging ring to find the gravity center of the roller box, the hanging ring can be bought into the hanging ring of the standard M24, a through hole with the diameter of 25 is drilled into the through hole, and the M24 screw can pass through the through hole.
The pre-finish rolling flat rolling is carried out for at least 2.5-3 hours, the disassembly is not good, the installation is not good, the hanger can be finished within 1.5-2 hours, the flat rolling roller box is saved for at least 1 hour each time, the service cycle of one roller box is half a year, pre-finish rolling is carried out on two flat rolling roller boxes, the flat rolling roller boxes are replaced at least four times per year according to the normal cycle, and the influences of objective factors, such as the factors of difficult hitting of the contact surface of a shaft head, damage of a thread buckle of the shaft head and the like, influence on the replacement of at least 3-5 roller boxes per year, so the number of replacement of the roller boxes is at least 7-9 times per year, the 7-9 hours are saved at least, the steel yield of 70 tons per hour can be more produced by 490-630 tons per year, the wire rod can produce 189 ten-thousand-yuan-one-year benefit according to 3000-one, more work can be completed in the same time; more importantly, the safety factor in the work is improved, and the core is not required to be lifted to remove the dryness of the hanging liner.
