Description

Technical Field

[0001] This utility model relates to the field of maintenance technology for wire rod air-cooling lines in steel rolling mills, specifically to a device for measuring the distance between the head rollers of a wire rod air-cooling line. Background Technology

[0002] Wire rod (coiled wire) is an important product of the modern steel industry, widely used in construction, bridges, fasteners, springs, wire ropes and other fields. After hot rolling, the temperature of wire rod is extremely high (usually 850℃-1050℃), and it needs to be cooled under controlled conditions (Steyrmo air cooling line is the mainstream process) to obtain the required metallographic structure (such as sorbite) and mechanical properties (strength, plasticity, toughness). The head roller conveyor of the air cooling line is a key transfer point for high-temperature wire rod after leaving the finishing mill and entering the air cooling area. It is responsible for smoothly and uniformly transporting the wire rod onto the air cooling conveyor belt and ensuring that the head of the wire rod is smoothly overlapped and enters the air cooling area.

[0003] If the roller spacing (the distance between the center lines of two adjacent rollers) is too large, the hot and soft wire will sag and swing between the rollers, which can easily cause "steel piling" (wire accumulation and entanglement), resulting in serious equipment damage, production interruption and safety accidents. If the spacing is too small, it may jam the wire or increase the conveying resistance, affecting the smooth running speed of the wire on the roller and thus affecting its overlapping state when entering the air-cooled conveyor belt. Poor overlapping can lead to uneven cooling, performance fluctuations or even belt breakage.

[0004] The production line needs to roll wires of different diameters (such as Φ5.5mm to Φ22mm). The roller spacing needs to be precisely adjusted and set according to the wire specifications to ensure that all specifications can be conveyed stably. Improper spacing may cause unnecessary friction between the wire and the roller sidewall or support, scratching the surface of the high-temperature wire.

[0005] During maintenance, it is necessary to measure the gap of the head roller conveyor of the air-cooled line. If the gap is too large, it needs to be adjusted or replaced. The measurement is done by using a saw blade to measure the gap, and then using calipers to read the data value. After measuring each gap, the number of saw blades is recorded and the reading is taken with calipers. Each measurement takes about 15 minutes, which is inefficient.

[0006] Therefore, there is an urgent need to design a device for measuring the distance between the head rollers of a wire air-cooled line to solve the problems of long measurement time, complex process, inaccurate readings and low efficiency in the existing technology. Utility Model Content

[0007] In view of the problems existing in the prior art, the purpose of this utility model is to provide a device for measuring the distance between the head rollers of a wire air-cooling line.

[0008] The technical solution adopted by this utility model to solve its technical problem is: a wire air-cooled line head roller spacing measuring device, including a cylinder, a lighting lamp and a transparent ruler. The cylinder has a structure with open ends and a hollow middle. An opening is provided on one side of the cylinder. The lighting lamp is fixedly connected to the opening on the side of the cylinder. The transparent ruler is fixedly connected to the bottom inside the cylinder.

[0009] Specifically, the cylinder is hollow inside, open at both ends, has openings on the side, and has dust covers at both ends, which are detachable end caps.

[0010] Specifically, there are two dust covers, which are made of rubber and have an inner diameter that matches the inner diameter of the cylinder.

[0011] Specifically, the lighting lamp is fixedly connected to an opening on the side of the cylinder, and the lighting lamp is equipped with a switch, which adjusts the brightness of the lighting lamp.

[0012] Specifically, the transparent ruler is fixedly connected to the inner bottom of the cylinder, and the transparent ruler has scale lines.

[0013] Specifically, the scale lines are equidistantly positioned in the center of the transparent ruler.

[0014] This utility model has the following beneficial effects:

[0015] This utility model designs a wire rod air-cooled line head roller gap measuring device, which changes the traditional measurement method using saw blades and calipers, improving measurement efficiency. Previously, measuring each gap took about 15 minutes, but now measuring the head roller gap only takes about 8 minutes, greatly improving work efficiency, speeding up the overall maintenance progress, reducing equipment maintenance time, and ensuring efficient production operation. The new tool is easy to operate; simply align the bottom with the gap to clearly see the data, avoiding tedious steps such as recording the number of saw blades and taking multiple measurements. The operation is simpler, reducing the labor intensity of workers and reducing measurement errors that may be caused by cumbersome operation, saving time and effort. Attached Figure Description
