Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of continuous casting machines, namely a tool for measuring the width of hot-rolled slabs, which is used for manually measuring the width of slabs entering a heating furnace online. Background Art
[0002] In the prior art, there is no slab width measuring device between the swing shear of the thin slab continuous casting machine and the tunnel-type soaking furnace, and manual measurement with a tape measure is required. Due to the particularity of the thin slab continuous casting production line, it is necessary to maintain the production continuity of the production line. When the casting speed fluctuates, the slab width will change. The width of the finished strip coil is affected and the quality is disputed. Therefore, when the casting speed fluctuates, it is necessary to measure the width of the slab entering the furnace to provide a basis for the subsequent rolling adjustment and ensure that the width of the finished product is within the tolerance range. When the slab width is measured manually with a tape measure, on the one hand, the slab moves forward, and the measuring personnel need to move forward in the direction of the slab movement. The tape measure is not easy to fix, and the measurement is inaccurate, and there are safety hazards such as high temperature burns. On the other hand, the temperature of the slab after shearing by the swing shear is above 800°C. The tape measure placed on the slab is affected by the high temperature and instantly deformed and damaged. It can only be "measured one by one", and it cannot be reused, which increases material consumption. Utility Model Content
[0003] The utility model aims to provide a tool for measuring the width of a hot-rolled slab in view of the above-mentioned shortcomings, which can be used to directly measure the width of the slab when the casting speed changes.
[0004] The technical solution of the utility model is: a tool for measuring the width of a hot-rolled slab, characterized in that it comprises a measuring rod, a front measuring arm is provided at the front end of the measuring rod, a handle is provided at the rear end of the measuring rod, a limit stop is provided at the front end of the handle, the measuring rod is covered with a sleeve, a rear measuring arm corresponding to the front measuring arm is provided at the front end of the sleeve, a handle is provided on the sleeve, and a locking device is provided on the sleeve.
[0005] The above scheme also includes:
[0006] The locking device is a rotatable screw rod which passes through the sleeve and is connected to the top of the measuring rod.
[0007] The measuring rod is provided with a length scale, and the 0 scale is from the front measuring clamp arm.
[0008] The handle is a wooden handle.
[0009] The advantages of the utility model are: 1. The use of the caliper structure at both ends solves the problem that the tape measure is difficult to fix when measuring. The measurement is simple and easy to operate. The measuring personnel do not need to move with the slab during the measurement process, effectively avoiding the safety hazard of high temperature burns. 2. The tool has enhanced resistance to high temperature deformation and can be reused many times, reducing material consumption costs.
[0010] The embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Figure 1 It is a simplified structural diagram of the utility model. DETAILED DESCRIPTION
[0012] See also Figure 1 The names of the parts are as follows: handle 1, sleeve 2, locking device 3, handle 4, measuring rod 5, front measuring arm 6, limit stop 7, rear measuring arm 8.
[0013] See also Figure 1 A tool for measuring the width of a hot-rolled slab includes a measuring rod 5, a front measuring arm 6 is provided at the front end of the measuring rod 5, and a length scale is provided on the measuring rod 5, and the scale is 0 from the front measuring arm 6. A handle 1 is provided at the rear end of the measuring rod 5, which is a wooden handle, and a limit stop 7 is provided at the front end of the handle 1. The measuring rod 5 is sleeved with a movable sleeve 2, and a rear measuring arm 8 corresponding to the front measuring arm 6 is provided at the front end of the sleeve 2. A handle 4 is provided on the sleeve 2, and a locking device 3 is provided on the sleeve 2. The locking device 3 is a rotatable screw that passes through the sleeve 2 and is connected to the top of the measuring rod 5.
[0014] Select a Φ8×2000mm long round steel as the measuring rod 5, which is also the scale. Select a Φ10×500mm long steel pipe as the sleeve 2, which is sleeved on the measuring rod 5. Make a locking device 3 on the sleeve 2, open a Φ6 hole, and tighten it with a Φ6×10mm screw. Make a handle 4 with a Φ8mm round steel and weld it to the sleeve 2. Make a front measuring arm 6 and a rear measuring arm 8 with a Φ8mm round steel, and weld them to the front end of the measuring rod 5 and the front end of the sleeve 2 respectively.
[0015] How to use: When you need to use this tool to measure the width of the slab, hold the measuring rod 5 on one side and move the movable end sleeve 2 toward the handheld handle 1 to ensure that the movable sleeve 2 and the fixed end are open to a sufficient width. Use the fixed end front measuring clamp arm 6 on one side of the slab, and then quickly move the movable sleeve 2 forward until the rear measuring clamp arm 8 is clamped on the other side of the slab. At this time, tighten the locking device 3 above the sleeve 2, fix the movable end sleeve 2, and read the scale reading displayed by the rear measuring clamp arm 8 on the measuring rod 5, which is the slab width data.
[0016] The above description is only a specific implementation of the present utility model, and various examples do not constitute a limitation on the essential content of the present utility model.
