Description

Technical Field

[0001] This utility model relates to the field of steel plate production technology, specifically to a hoisting protective kit. Background Technology

[0002] During the loading and unloading of coiled steel, steel wire clips are usually used for hoisting by passing through the inside of the coiled steel. At the contact point between the steel wire clip and the coiled steel, the steel wire clip is prone to being cut or the surface of the coiled steel may be damaged. To avoid this, padding is usually used for isolation. For example, the utility model patent with authorization announcement number CN2547664Y, entitled "Coiled Steel Inner Corner Protector", includes an "L"-shaped channel steel. A rubber plate is fixed on the contact surface between the "L"-shaped channel steel and the coiled steel cylinder. A shackle is provided on the inner arc surface above the "L"-shaped channel steel. It can be inserted into the inside of the coiled steel through the "L"-shaped channel steel. The arc-shaped rubber plate can fit the arc surface of the inner side of the coiled steel without damaging it. In addition, a handle is provided on the side of the protector so that workers will not injure their arms when operating it.

[0003] However, during the loading of the coiled steel, in order to ensure a more even distribution of force between the steel wire and the coiled steel, two workers need to stand at each end of the coiled steel and simultaneously hold up the aforementioned safety device until the steel wire is completely against the safety device during its ascent and it does not fall. During the unloading of the coiled steel, in order to prevent the aforementioned safety device from falling directly and injuring the coiled steel, damaging the ground, or injuring itself, two workers need to stand at each end of the coiled steel and simultaneously catch the aforementioned safety device. Therefore, the aforementioned safety device results in a high level of labor intensity. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a hoisting protection kit to solve the technical problem that the existing protective device requires two people to operate during the loading and unloading of coiled steel, which results in high labor intensity.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0006] This utility model provides a hoisting protection kit, including protective components. The protective components are arranged in pairs. Each protective component includes a first locking block, a second locking block, and a connecting member. The first locking block and the second locking block are distributed vertically opposite each other. The two ends of the connecting member are respectively connected to the first locking block and the second locking block. The bottom surface of the first locking block has a first locking groove adapted to the outer side of the coiled steel, and one side of the first locking block has a first arc groove. The top surface of the second locking block has a second locking groove adapted to the inner side of the coiled steel, and one side of the second locking block has a second arc groove.

[0007] In some embodiments, a first arc surface is provided on one side of the first card block, and the first arc groove is formed on the first arc surface.

[0008] In some embodiments, a second arc surface is provided on one side of the second card block, and the second arc groove is formed on the second arc surface.

[0009] In some embodiments, the bottom surface of the first card slot is recessed.

[0010] In some embodiments, the bottom surface of the second slot is raised.

[0011] In some embodiments, the connector is a telescopic rod.

[0012] In some embodiments, the telescopic rod includes a screw, a sliding sleeve, and a threaded sleeve. The top end of the screw is fixedly connected to the first locking block, the bottom end of the sliding sleeve is fixedly connected to the second locking block, the bottom end of the screw is slidably sleeved on the top end of the sliding sleeve, one end of the threaded sleeve is rotatably connected to the top end of the sliding sleeve, the other end of the threaded sleeve is sleeved on the screw, and the inner wall of the threaded sleeve is threadedly connected to the outer wall of the screw.

[0013] In some embodiments, the outer wall of the threaded sleeve is provided with anti-slip texture.

[0014] In some embodiments, the edges of both the first card slot and the second card slot are rounded.

[0015] In some embodiments, the edges of both the first arc groove and the second arc groove are rounded.

[0016] Compared with the prior art, the hoisting protective kit provided by this utility model forms a protective structure for the coiled steel by setting a first locking block and a second locking block. By setting a connecting piece, when the first locking block is connected to the outside of the coiled steel through the first locking groove, it can suspend the second locking block in the air and make the inside of the coiled steel embedded in the second locking groove.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0023] To address the technical problem that the protective device requires two people to operate during the loading and unloading of coiled steel, resulting in high labor intensity, this utility model provides a hoisting protective kit that allows for operation by one person, reducing labor intensity.

[0024] It should be noted that the hoisting protection kit described in this utility model is used for, but not limited to, coiled steel. For ease of explanation, this utility model only uses the application of a hoisting protection kit to coiled steel as an example. The principle of applying a hoisting protection kit to other types of equipment is essentially the same as that applied to coiled steel, and will not be described in detail here.

[0025] Please see Figure 1 - Figure 4 ,in Figure 1 This is a schematic diagram of the structure of a hoisting protective kit in one embodiment of the present invention. The hoisting protective kit includes a protective component 1, which is arranged in pairs. The protective component 1 includes a first locking block 11, a second locking block 12, and a connecting member 13. The first locking block 11 and the second locking block 12 are distributed vertically opposite each other. The two ends of the connecting member 13 are respectively connected to the first locking block 11 and the second locking block 12. The bottom surface of the first locking block 11 is provided with a first locking groove 111 that is adapted to the outer side of the coiled steel 2. The first locking block 11 is provided with a first arc groove 112 on one side. The top surface of the second locking block 12 is provided with a second locking groove 121 that is adapted to the inner side of the coiled steel 2. The second locking block 12 is provided with a second arc groove 122 on one side.

[0026] In this embodiment, the first locking block 11 and the second locking block 12 form a protective structure for the coiled steel 2. The connecting piece 13 allows the first locking block 11 to be connected to the outside of the coiled steel 2 via the first locking groove 111, while the second locking block 12 is suspended in the air and the inside of the coiled steel 2 is embedded in the second locking groove 121. This ensures that the protective component 1 will not fall off after being installed in the preset position, eliminating the need for staff to hold it up continuously. Only one staff member is required to complete the installation and removal of the two protective components 1, resulting in low labor intensity.

[0027] Furthermore, the first arc groove 112 and the second arc groove 122 can limit the position of the lifting rope 3, preventing the lifting rope 3 from being misaligned during the lifting process.

[0028] In one embodiment, a first arc surface 113 is provided on one side of the first card block 11, and a first arc groove 112 is formed on the first arc surface 113.

[0029] In this embodiment, the suspension ropes 3 above the first locking block 11 in both protective components 1 converge on the hook, which causes the suspension ropes 3 to change in angle. The setting of the first arc surface 113 makes the first locking block 11 and the suspension ropes 3 more compatible, and the connection between the suspension ropes 3 and the first locking block 11 is smoother, without sharp bends, thus extending the service life of the suspension ropes 3.

[0030] In one embodiment, a second arc surface 123 is provided on one side of the second card block 12, and a second arc groove 122 is formed on the second arc surface 123.

[0031] In this embodiment, the suspension rope 3 below the second locking block 12 in the two protective components 1 will pass through the inner side of the coiled steel 2 and be in a horizontal state. The setting of the second arc surface 123 can make the second locking block 12 and the suspension rope 3 more compatible, so that the suspension rope 3 will not bend at 90° and extend the service life of the suspension rope 3.

[0032] In one embodiment, please refer to Figure 4 The bottom surface of the first slot 111 is concave.

[0033] In this embodiment, the first slot 111 is made to better fit the outer side of the coiled steel 2.

[0034] In one embodiment, please refer to Figure 4 The bottom surface of the second slot 121 is raised.

[0035] In this embodiment, the second slot 121 is made to fit the inner wall of the coiled steel 2 better.

[0036] In one embodiment, the connector 13 is a telescopic rod 131.

[0037] In this embodiment, by setting the telescopic rod 131, the operator can adjust the distance between the first locking block 11 and the second locking block 12 according to the different thicknesses of the coiled steel 2, so that the device can be applied to coiled steel 2 of different thicknesses.

[0038] Furthermore, based on the uniformity of the raw material of coil steel 2, the factory ensures that all coil steel 2 have the same thickness, and the connecting part 13 can also use a fixing rod, which reduces the cost.

[0039] In one embodiment, the telescopic rod 131 includes a screw 1311, a sliding sleeve 1312, and a threaded sleeve 1313. The top end of the screw 1311 is fixedly connected to the first locking block 11, the bottom end of the sliding sleeve 1312 is fixedly connected to the second locking block 12, the bottom end of the screw 1311 is slidably sleeved on the top end of the sliding sleeve 1312, one end of the threaded sleeve 1313 is rotatably connected to the top end of the sliding sleeve 1312, the other end of the threaded sleeve 1313 is sleeved on the screw 1311, and the inner wall of the threaded sleeve 1313 is threadedly connected to the outer wall of the screw 1311.

[0040] In this embodiment, the inner wall of the threaded sleeve 1313 is provided with an internal thread, which is threadedly connected to the screw 1311. This allows the operator to drive the screw 1311 in and out of the sliding sleeve 1312 when the threaded sleeve 1313 is twisted, thereby realizing the adjustable distance between the first locking block 11 and the second locking block 12. At the same time, in order to prevent the threaded sleeve 1313 from disengaging from the sliding sleeve 1312 during the twisting process, a convex ring is fixedly connected to the inner wall of the threaded sleeve 1313. The outer wall of the sliding sleeve 1312 is provided with an annular groove. The convex ring is adapted to the annular groove and rotates to be embedded in the annular groove, so that the threaded sleeve 1313 will not fall off during the twisting process.

[0041] Furthermore, in order to reduce the friction between the threaded sleeve 1313 and the sliding sleeve 1312, the threaded sleeve 1313 and the sliding sleeve 1312 can fix the bearing, with the inner ring of the bearing fixedly connected to the sliding sleeve 1312 and the outer ring of the bearing fixedly connected to the threaded sleeve 1313.

[0042] In one embodiment, the outer wall of the threaded sleeve 1313 is provided with anti-slip texture.

[0043] In this embodiment, it is convenient for workers to twist the threaded sleeve 1313 to avoid slippage.

[0044] In one embodiment, the edges of both the first card slot 111 and the second card slot 121 are rounded.

[0045] In this embodiment, the first slot 111 or the second slot 121 is prevented from scratching the surface of the coiled steel 2.

[0046] In one embodiment, the edges of the first arc groove 112 and the second arc groove 122 are both rounded.

[0047] In this embodiment, to prevent the edges of the first arc groove 112 or the second arc groove 122 from being too sharp and scratching the staff, and to make it easier for the staff to pick up.

[0048] To better understand this utility model, the following is combined with... Figures 1 to 4 The technical solution of this utility model is described in detail below:

[0049] First, the worker installs a protective component 1. Based on the thickness of the coiled steel 2, the threaded sleeve 1313 is twisted to adjust the telescopic rod 131 to a suitable length. Then, the first locking block 11 is attached to the highest point on the outer side of the coiled steel 2 via the first locking slot 111. Subsequently, the threaded sleeve 1313 is twisted to connect the second locking slot 121 to the highest point on the inner side of the coiled steel 2, meaning the second locking block 12 abuts against the highest point on the inner side of the coiled steel 2. This completes the installation of one protective component 1. At this point, the first locking block 1... Under the action of 1, the protective component 1 is suspended in the air and will not fall; then, the staff installs another protective component 1 in the same way; finally, the hoisting rope 3 passes through the inside of the coiled steel 2, and the hook drives the hoisting rope 3 to rise together under the drive of the crane until the hoisting rope 3 is embedded in the first arc groove 112 and the second arc groove 122. The entire operation can be completed by one person without the need for two people. Moreover, during the loading and unloading process, the staff does not need to hold the protective component 1 or support the protective component 1 to prevent it from falling directly, which effectively reduces the labor intensity.
