Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cold rolling equipment maintenance, more particularly to a winding drum sector block disassembly and inspection safety device and application method. BACKGROUND

[0002] In the production of cold-rolled plates, the winding drums of the uncoiler and coiler are the core equipment for realizing continuous rolling of the plates, and their performance directly affects the product quality and production efficiency. The typical structure of the winding drum includes a main shaft, a wedge sleeve (formed by a wedge and a sleeve), a sector block, a head roller, a conical sleeve, and an expansion cylinder. During operation, the wedge sleeve is axially moved by a hydraulic drive core shaft to expand or shrink the winding drum to clamp or release the plate.

[0003] Due to the high frequency of expansion and shrink cycles and the tension of the plate, a large gap is easily generated between the sector block and the wedge sleeve due to wear. During the regular disassembly, inspection, and repair, the head roller, the conical sleeve, and then the sector blocks are removed one by one. The traditional disassembly and inspection process has the following significant defects:

[0004] Safety hazards are prominent: due to the gap wear, when adjusting the position of the sector block of the rotating winding drum, the sector block is easy to slide along the wedge slope, and there have been historical accidents that may cause personnel casualties, deformation of the sector block body, or damage to the equipment below (such as a steel coil trolley and hydraulic pipelines).

[0005] Low operational efficiency: the traditional method relies on a hand-operated hoist to tighten the sector block, and each rotation of the winding drum requires the hoist to be tightened first, then loosened after rotation. The disassembly and inspection of a single sector block is time-consuming and labor-intensive.

[0006] Insufficient reliability: during the removal of the sector block after loosening the hand-operated hoist, the lowermost sector block is always in an unstable state, and the risk of sliding cannot be completely eliminated, posing a safety hazard.

[0007] Poor adaptability: the frequent tightening and loosening of the hand-operated hoist, and the sliding connection between the hoist hook and the sector block, pose certain operational risks.

[0008] The above problems make it difficult to ensure the safety and economy of the winding drum disassembly and inspection operation, and there is an urgent need for a safety device that can achieve stable positioning of the sector block, convenient operation, and strong adaptability. SUMMARY

[0009] To solve the problems in the prior art, the present application aims to provide a winding drum sector block disassembly and inspection safety device and application method that can realize safe and controllable disassembly and inspection of the sector block, improve operational efficiency, and reduce labor costs.

[0010] The present application adopts the following technical solutions:

[0011] The application discloses a winding drum sector block dismounting and inspecting safety device, which comprises a ring-shaped base, a supporting assembly and a locking mechanism, the ring-shaped base is provided with connecting portions at two ends, the locking mechanism is installed on the connecting portions, the supporting assembly is provided with a plurality of supporting assemblies, the supporting assembly comprises a functional plate and a screw rod, the outer side of the ring-shaped base is fixed with a nut one, one end of the screw rod is installed at the position of the nut one, the functional plate is installed on the screw rod, and the functional plate is attached to the end portion of the sector block.

[0012] Further, the functional plate is sleeved on the screw rod, both ends of the functional plate are provided with nuts two, and the nuts two are threadedly connected with the screw rod.

[0013] Further, the number of the nuts one is equal to that of the screw rods and the functional plates, and the nuts one are connected with the ring-shaped base through welding.

[0014] Further, the number of the functional plates and the screw rods is three, wherein two screw rods are located on the same straight line, and the other screw rod is perpendicular to the other two screw rods, and the other screw rod is located at the middle of the other two screw rods.

[0015] Further, the locking mechanism comprises connecting bolts and fixing nuts, the connecting bolts pass through the mounting holes of the two connecting portions, and the fixing nuts are threadedly connected with the connecting bolts.

[0016] Beneficial effects

[0017] The safety is remarkably improved: the mechanical positioning of the sector block is realized through the supporting assembly, the flexible constraint of the traditional hand-operated hoist is replaced, the sliding risk in the rotating process is completely eliminated, the safety is improved through actual application verification, and the accident rate is zero in the dismounting and inspecting process.

[0018] The work efficiency is improved: the dismounting and inspecting time of a single sector block is greatly shortened, the labor cost is greatly reduced, and the labor intensity is also reduced.

[0019] The structure is simple and reliable: all components are mechanical structures, do not need hydraulic or electrical assistance, and have long service life.

[0020] The economy is strong: the manufacturing cost is low, and the economy is strong.

[0021] The operation is convenient: the structure is convenient for quick tightening and loosening, special tools are not needed, and the dependence on the skills of the operators is reduced. DESCRIPTION OF DRAWINGS
