Description

Technical Field

[0001] The utility model relates to a spool, in particular to a spool which is easy to lift, and belongs to the technical field of spools. Background Art

[0002] A spool is a tool used to wind metal wire or wire rope. The specifications and materials of the spool vary depending on the material and specifications of the wire rope being wound. Spools for winding steel wire are generally made of steel plates, while wooden spools can be used for winding fine steel wire and non-ferrous metal wire. With the development of the times, the use of plastic spools is also increasing.

[0003] In the existing I-spool, during the lifting process, ropes are generally tied through the openings in the central shaft for lifting, which is cumbersome to operate. Alternatively, through holes are opened on the end wheels of some I-spools for lifting, but it is usually difficult to quickly and effectively connect the through holes with the hooks, and the operation is not satisfactory. In addition, there is also a problem of mismatch in size between the hooks and the through holes. Therefore, in order to solve the above problems, an I-spool that is easy to lift is proposed. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an I-shaped pulley which is easy to lift. The I-shaped pulley can be quickly and firmly and effectively lifted and connected through the lifting rings by arranging a multi-symmetrical and flippable lifting ring structure on the outer side of the end wheel. The multi-symmetrical lifting ring arrangement can also make the I-shaped pulley more stable during lifting. In addition, when the lifting is completed, the lifting rings can be flipped and put away without taking up extra space, which solves the technical problems in the prior art of inconvenient lifting and fixing operations of the I-shaped pulley and the lifting structure taking up extra space.

[0005] To solve the above problems, the following technical solutions are provided:

[0006] An I-shaped pulley that is easy to lift is designed, comprising a central shaft, end wheels are sleeved on both ends of the central shaft, the central shaft and the end wheels are fixedly connected by connecting bolts, a stiffening rib is fixedly arranged in the concave circular groove on the outer side surface of the end wheel, a rotation constraint cylinder is fixedly embedded in the middle of the stiffening rib, a lifting ring is rotatably arranged between two adjacent rotation constraint cylinders of the stiffening rib, and a reinforcement plate is fixedly arranged in the concave circular groove on the outer side surface of the end wheel.

[0007] The above-mentioned structural form can flip the lifting ring to make it rotate out during lifting and fixing. The lifting ring can make the fixed connection of the lifting rope or hook very quick and reliable. Moreover, since the arrangement of the lifting ring is a multi-point symmetrical arrangement, the I-spool can be made more stable during lifting. When the lifting ring is not needed, it can be flipped down and will not take up extra space.

[0008] Furthermore, six bolt sleeves with equal spacing are embedded in the end of the central shaft, and six bolt holes are correspondingly opened on the convex ring structure in the middle of the end wheel. The thread size of the bolt sleeve matches the thread size of the connecting bolt.

[0009] The above-mentioned structural form can realize a firm connection between the central shaft and the end wheels, and the assembled structure enables the I-shaped wheel to have a higher space utilization rate during transportation.

[0010] Furthermore, a shock-proof rubber washer is provided on the fixing pad below the connecting bolt nut.

[0011] The above-mentioned structural form can improve the anti-seismic ability of the connecting bolts and can effectively prevent the connection of the connecting bolts from loosening, which causes the connection between the central shaft and the end wheel to shake.

[0012] Furthermore, the stiffening rib plate is a metal plate structure with lower ends and higher middle, and the two ends and the bottom thereof are fixedly welded to the end wheels respectively.

[0013] The above-mentioned structural form can improve the overall rigidity of the end wheel and make it less prone to local deformation. At the same time, the stiffening ribs are also responsible for transmitting the force applied to the lifting ring by the external lifting structure to the I-shaped wheel as a whole.

[0014] Furthermore, the lifting ring includes a ring body, which is a U-shaped metal part with rotating shafts fixed at both ends, and the rotating shafts at both ends extend into the rotation constraint cylinder, and anti-slip end plates are fixed at the ends of the rotating shafts at both ends of the ring body.

[0015] The above-mentioned structural form enables the lifting ring to rotate freely without the end falling out of the rotation constraint cylinder, which can prevent the end from slipping due to the force applied to the lifting ring during the lifting process.

[0016] Furthermore, the anti-slip end piece is provided with a hole for a fixing bolt, and the end surface of the ring body rotation shaft is provided with a corresponding hole for a fixing bolt, and the anti-slip end piece and the ring body are fixedly connected by a fixing bolt.

[0017] The above structure is used to realize the detachable connection between the anti-slip end piece and the ring body. When the ring body is damaged and needs to be replaced, the two sections of the ring body can be taken out from the rotation constraint cylinder by removing the anti-slip end piece and cutting the ring body.

[0018] Furthermore, the reinforcing plate is a rectangular metal plate structure, and both ends and the bottom thereof are fixedly welded to the end wheels respectively.

[0019] The above-mentioned structural form can improve the overall rigidity of the end wheel and make it less prone to local deformation.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] In the utility model, the freely reversible lifting ring is provided, which can be turned over and extended during the lifting and fixing. The ring-shaped structure can make the fixed connection of the lifting rope or the hook very fast and reliable, greatly improving the efficiency of the fixing work in the early stage of lifting. In addition, since the arrangement of the lifting ring is a multi-point symmetrical arrangement, the I-spool can be made more stable during lifting. When the lifting ring is not needed, it can be turned over and put down without taking up extra space.

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0031] like Figure 1 、 Figure 3 、 Figure 4 As shown, the embodiment provides an I-shaped pulley that is easy to lift, including a central axis 1, end wheels 2 are sleeved on both ends of the central axis 1, the central axis 1 and the end wheels 2 are fixedly connected by connecting bolts 3, a stiffening rib 4 is fixedly provided in the concave circular groove on the outer side of the end wheel 2, a rotation constraint cylinder 41 is fixedly buried in the middle of the stiffening rib 4, and a lifting ring 5 is rotatably provided between two adjacent rotation constraint cylinders 41 of the stiffening rib 4. When lifting and fixing, the lifting ring 5 is flipped over to make it rotated out, and the lifting ring 5 can make the fixed connection of the lifting rope or the hook very fast and reliable, and because the arrangement of the lifting ring 5 is a multi-point symmetrical arrangement, the I-shaped pulley can be more stable during lifting. When the lifting ring 5 is no longer needed, it can be turned over and put down without taking up any extra space. The lifting ring 5 includes a ring body 51, which is a U-shaped metal part with rotating shafts fixed at both ends, and the rotating shafts at both ends extend into the rotation constraint cylinder 41. The ends of the rotating shafts at both ends of the ring body 51 are fixed with anti-slip end pieces 52. The above-mentioned structural form allows the lifting ring 5 to rotate freely without the ends slipping out of the rotation constraint cylinder 41, and can prevent the ends of the lifting ring 5 from slipping due to the force applied to them during the lifting process. A reinforcing plate 6 is fixed in the concave circular groove on the outer side of the end wheel 2. The reinforcing plate 6 is a rectangular metal plate structure, and its two ends and the bottom are fixedly welded to the end wheel 2 respectively. This structural form can improve the overall rigidity of the end wheel 2 and make it less prone to local deformation.

[0032] like Figure 2 As shown, this embodiment provides an I-shaped pulley that is easy to lift. The stiffening ribs 4 are metal plate structures that are low at both ends and high in the middle. The two ends and the bottom are fixedly welded to the end wheel 2 respectively. The above-mentioned structural form can improve the overall stiffness of the end wheel 2 so that it is not easy to deform locally. At the same time, the stiffening ribs 4 are also responsible for transmitting the force applied to the lifting ring 5 by the external lifting structure to the I-shaped pulley as a whole.

[0033] like Figure 5 As shown, this embodiment provides an I-shaped wheel that is easy to lift. Six bolt sleeves 11 with equal spacing are embedded in the end of the central axis 1, and six bolt holes are correspondingly opened on the convex ring structure in the middle of the end wheel 2. The thread size of the bolt sleeve 11 matches the thread size of the connecting bolt 3. The above structural form can achieve a firm connection between the central axis 1 and the end wheel 2. The assembled structure enables the I-shaped wheel to have a higher space utilization rate during transportation. A shock-proof rubber washer is provided on the fixing pad under the nut of the connecting bolt 3. The above structural form can improve the seismic resistance of the connecting bolt 3, and can effectively prevent the connection of the connecting bolt 3 from loosening, resulting in shaking of the connection between the central axis 1 and the end wheel 2.

[0034] like Figure 4As shown, this embodiment provides an I-shaped pulley that is easy to lift. The anti-slip end piece 52 is provided with a hole for fixing bolts, and the end face of the rotating shaft of the ring body 51 is provided with a corresponding hole for fixing bolts. The anti-slip end piece 52 and the ring body 51 are fixedly connected by fixing bolts. The above-mentioned structural form is used to realize a detachable connection between the anti-slip end piece 52 and the ring body 51. When the ring body 51 is damaged and needs to be replaced, the two sections of the ring body 51 can be taken out from the rotation constraint cylinder 41 by removing the anti-slip end piece 52 and cutting off the ring body 51.

[0035] The use principle and use process of the utility model are as follows: the end wheels 2 are sleeved on the two end portions of the central axis 1 and the bolt holes are aligned, and then the two are fixedly connected as a whole with the connecting bolts 3, and then the cable winding work can be started; when the I-shaped pulley needs to be hoisted, the lifting ring 5 is turned over to extend it, and the annular structure can make the fixed connection of the lifting rope or the hook very fast and reliable, and because the arrangement of the lifting ring 5 is a multi-point symmetrical arrangement, the I-shaped pulley can be made more stable during hoisting; when the lifting ring 5 is not needed, it is turned over and put away, so as not to occupy extra space and improve space utilization.
