Description

Technical Field

[0001] This utility model relates to the field of strip steel production technology, specifically to a strip steel sampling tool for continuous acid leveling units. Background Technology

[0002] During the operation of the continuous acid leveling unit, it is necessary to sample the strip steel to ensure product quality. The conventional operation method is to wait for the strip steel to come to a stop, and then the sampling personnel enter the strip steel running area, approach the slitting shear, hold the strip steel by hand, and cut it. The operation process has safety risks such as scratches, falls, and cuts. Moreover, the size of the cut strip steel sample is generally large, which is inconvenient for a single operator to pick up.

[0003] Patent CN202400624U discloses a steel strip sample picking device, comprising a suction body, a handheld rod, a telescopic air tube, a vacuum pump, and a controller. The suction body consists of a rubber disc fixed to one end of the handheld rod and a metal disc embedded in the rubber disc. A cylindrical iron core and a proximity switch for position detection are installed on the lower surface of the metal disc, and a coil is wound on the iron core. The handheld rod is a hollow rod, which is connected to the vacuum pump through the telescopic air tube. The controller is connected to the vacuum pump, the coil, and the proximity switch through a cable. Although this structure can sample steel strips, it requires simultaneous control of the vacuum system and the electromagnetic system, resulting in a complex overall structure that increases the complexity of the equipment and the risk of failure. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a strip steel sampling tool for continuous acid leveling unit, which can effectively solve the problem of inconvenient strip steel sampling in the existing technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides a strip sampling tool for a continuous acid leveling unit, characterized in that it includes:

[0007] A strip sampling tool for a continuous acid leveling unit, characterized in that it comprises:

[0008] The sampling rod has a first mounting hole at the front.

[0009] The eye bolt has its threaded shaft fixedly connected to the first mounting hole via a nut, and its collar is located below the sampling rod.

[0010] A lifting eye magnet, wherein the lifting eye of the lifting eye magnet is connected to the collar of the lifting eye bolt;

[0011] And a scratch-resistant foot, which is fixedly connected to the lower front end of the sampling rod and is located in front of the first mounting hole.

[0012] Furthermore, it also includes a U-shaped lifting ring, which is connected between the lifting ring bolt and the lifting ring magnet.

[0013] Furthermore, the anti-scratch feet are made of rubber pads with bolts, and the anti-scratch feet are detachably and fixedly connected to the sampling rod.

[0014] Furthermore, the sampling rod is a hollow rod with a beveled end, and the bolts of the anti-scratch support extend into the beveled end and are fastened with nuts.

[0015] The technical solution provided by this utility model has the following advantages compared with the prior art:

[0016] 1. By setting a lifting ring magnet at the lower front of the sampling rod, the lifting ring magnet can be easily extended into the strip running area to adsorb the strip sample after shearing, avoiding the safety risks caused by entering the strip running area for sampling and manually taking the sample. Moreover, the overall structure is simple, easy to operate, and low in cost.

[0017] 2. The front end of the sampling rod is equipped with anti-scratch feet. When it is necessary to separate the lifting ring magnet and the strip steel sample, the rear end of the sampling rod is lifted with the anti-scratch feet as the fulcrum. The magnet can be easily separated from the strip steel sample by lever effect. Moreover, the anti-scratch feet are made of rubber and contact the surface of the strip steel sample, which can avoid damaging the sample during the process of removing the magnet.

[0018] 3. The eye bolt is detachably connected to the eye magnet via a U-shaped eye, which facilitates the replacement of eye magnets with different magnetic forces to be suitable for sampling steel strips of different sizes, thus improving the applicability of the device. In addition, the sampling rod, eye bolt, eye magnet, U-bolt, and anti-scratch support can all be detachably connected, which facilitates the maintenance and replacement of parts.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] First Embodiment

[0033] like Figures 1-2 As shown, this utility model provides a strip steel sampling tool for a continuous acid leveling unit, including a sampling rod 1, a lifting eye bolt 2, a lifting eye magnet 3, and a scratch-resistant support 4. The lifting eye magnet 3 is connected to the lower front part of the sampling rod 1 through the lifting eye bolt 2, and the scratch-resistant support 4 is fixedly connected to the front end of the sampling rod 1, and the scratch-resistant support 4 is located in front of the lifting eye magnet 3.

[0034] Specifically, the sampling rod 1 is a hollow square tube structure with a length of 1400mm, which allows the sampling personnel to stand outside the strip running area and ensures that the length of the rod will not increase the difficulty of use. A first mounting hole 101 is provided at a position 160mm from the front end, and a second mounting hole 102 is provided in front of the first mounting hole 101.

[0035] The eye bolt 2 consists of a collar 201 and a screw 202. The screw 202 is fixedly connected to the collar 201. The screw 202 passes through the first mounting hole 101 from bottom to top and is tightened by the first nut 5, thereby detachably and fixedly connecting the eye bolt 2 to the sampling rod 1. The collar 201 of the eye bolt 2 is located below the sampling rod 1.

[0036] The lifting eye magnet 3 consists of a lifting eye 301 and a magnet 302. The magnet 302 is a circular magnet, and the lifting eye 301 is a closed lifting eye, which is detachably and fixedly connected to the magnet 302. This structure is existing technology, so it will not be described in detail in this embodiment. The collar 201 of the lifting eye bolt 2 is connected to the lifting eye 301 of the lifting eye magnet 3. In this embodiment, the magnet 302 is a neodymium iron boron magnet with a diameter of 50mm and a magnetic force of 250kg. In actual use, it can meet the requirements for making strip steel samples of all rolling specifications from 0.7mm to 5.0mm. It should also be noted that in the specific installation process, since the lifting eye magnet 3 is generally not replaced after selection, it is directly connected to the lifting eye bolt 2 in this embodiment. During assembly, the collar 201 is first cut open, then the lifting eye 301 is fastened to the collar 201, and finally the opening is welded and sealed.

[0037] The anti-scratch foot 4 uses a rubber screw pad, which is existing technology. The specific structure will not be described in detail. The screw of the anti-scratch foot 4 passes through the second mounting hole 102 and is fixed to the sampling rod 1 by the second nut 6. The rubber pad of the anti-scratch foot 4 is located below the sampling rod 1.

[0038] In addition, in this embodiment, the front end of the sampling rod 1 is set as a beveled end, forming as follows: Figure 2 and Figure 3 The sampling rod 1 shown is configured with a short upper end and a long lower end, and the second mounting hole 102 is located on the lower end of the sampling rod 1 where the oblique end is located, so as to facilitate the installation and fixation of the anti-scratch support 4.

[0039] When using this device to sample strip steel samples, the operator holds the rear of the sampling rod 1 and inserts the magnet 302 into the steel running area. The lower end of the magnet 302 contacts the upper surface of the strip steel sample to attract the sample. Then, the sampling rod 1 is moved to place the strip steel sample on the ground. Next, using the anti-scratch support 4 as a fulcrum, the rear end of the sampling rod 1 is rotated upward until the magnet 302 detaches from the upper surface of the strip steel sample, thereby separating the device from the strip steel sample and completing the strip steel sample sampling operation.

[0040] This device avoids the safety risks associated with entering the strip steel operating area for sampling and manually handling the sample plate. When separating the device from the strip steel sample plate, the anti-scratch support 4 serves as a fulcrum, and the lever principle allows the magnet 302 to be easily separated from the strip steel sample plate, greatly reducing labor intensity and improving the convenience of sampling operations. In addition, the lower end face of the anti-scratch support 4 is equipped with a rubber pad, which can prevent the sampling rod 1 from scratching the surface of the strip steel sample plate during the separation process.

[0041] Second Embodiment

[0042] like Figure 3 As shown, this embodiment provides another strip sampling tool for continuous acid leveling units. Its overall structure is the same as that of the first embodiment. The difference is that a U-shaped lifting ring 7 is also provided between the lifting ring bolt 2 and the lifting ring magnet 3. During installation, the lifting ring bolt 2 is first fixed to the sampling rod 1. Then, after removing the screw and nut of the U-shaped lifting ring 7, the U-shaped ring body of the U-shaped lifting ring 7 passes through the lifting ring 301 of the lifting ring magnet 3. Then, the bolt of the U-shaped lifting ring 7 passes through the collar 201 of the lifting ring bolt 2 and is tightened by the nut. Thus, the lifting ring bolt 2 and the lifting ring magnet 3 are connected by the U-shaped lifting ring 7. By setting the U-shaped lifting ring 7, it is convenient to replace the lifting ring magnet 3 with different suction forces, thereby adapting to different strip sample sampling sizes.

[0043] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
