[0022] It is worth mentioning that the bottom end of the fixed frame 1 is provided with a pad groove 104, and the bottom end of the other fixed frame 1 is connected with a pad 103 by bolts, and the pad 103 is slidingly connected in the pad groove 104. The utility model places the pad 103 below the cold-rolled strip coil, and provides flexible support for the bottom end of the cold-rolled strip coil when the cold-rolled strip coil falls more due to weight.
[0023] It is worth noting that the bottom end of the mounting rod 3 is slidably connected to a groove 304, and the groove 304 is located at the top of the workbench. This invention provides a channel for the mounting rod 3 to slide through the groove 304, allowing the fixing member 303 to be adjusted in lateral position to match the position of the center hole of the cold-rolled strip steel coil.
[0024] In embodiments of this utility model, to ensure that the fixing member 303 can function as a fixing element when inserted into the center hole of cold-rolled strip steel coils of different diameters, such as... Figure 4 The fixing member 303 has a spiral structure, with its width gradually decreasing from one end to the other, and the narrower end of the fixing member 303 being closer to the center hole of the cold-rolled strip steel coil. In this invention, the fixing member 303, with its spiral structure, is initially inserted into the cold-rolled strip steel coil from its narrower end, and then gradually increases in width until it matches the center hole. This prevents the steel coil from swaying and avoids impact damage caused by gaps between the center hole and the fixing member 303. The fixing member 303 of this invention can adapt to center holes of different diameters, preventing the steel coil from swaying and better fulfilling its limiting function.
[0025] As another embodiment of this utility model, in order to be able to match steel coils of different widths, such as Figure 5 Another fixed frame 1 has a guide block 4 bolted to one side. Two parallel guide plates 401 are provided on both sides of the guide block 4, and the guide block 4 is slidably connected between the two guide plates 401. Ten mounting holes 402 are provided on each guide plate 401, and a limiting rod 403 is inserted into each mounting hole 402. The limiting rod 403 is inserted into the guide block 4, and its two ends extend to the outer sides of the two guide plates 401, where two nuts 404 are detachably connected. This invention allows the guide block 4 to slide between the two guide plates 401, driving the other fixed frame 1 to move. The limiting rod 403 then fixes the moved guide block 4, adjusting the distance between the two fixed frames 1. This invention can adapt to steel coils of different diameters and is easy to use.
[0026] Working principle: This embodiment provides a cold-rolled strip steel thickness gauge. In use, a forklift is used to fork the cold-rolled strip steel coil onto the pallet 102. The buffer support 101 provides buffer for the pallet 102 and sinks down, so that the pallet 102 enters the fixed frame 1, allowing the lower part of the cold-rolled strip steel coil to enter the fixed frame 1, restricting the longitudinal movement of the cold-rolled strip steel coil. Then, by moving the mounting rod 3, the mounting rod 3 slides in the slide groove 304, so that the fixing part 303 is aligned with the center hole of the cold-rolled strip steel coil. The cylinder 301 is opened, driving the fixing part 303 to move forward and insert into the center hole, restricting the lateral movement of the cold-rolled strip steel coil. Then, by placing the extended steel strip onto the auxiliary roller 201, the thickness gauge 202 detects the thickness of the steel strip.
[0027] When the diameter of the cold-rolled strip coil is adjusted, the nuts 404 are unscrewed to pull out the limiting rods 403, the guide blocks 4 are pushed to slide in the guide plates 401, the positions of the two fixed frames 1 are adjusted to a proper distance, the limiting rods 403 are reinserted into the guide blocks 4 through the mounting holes 402, the nuts 404 at both ends are reinstalled to limit the positions of the guide blocks 4, the position adjustment of the fixed frames 1 is completed, and then the cold-rolled strip coil is placed.
