Description

Technical Field

[0001] This utility model relates to the field of iron weight technology, specifically an anti-collision iron weight. Background Technology

[0002] In fields such as power systems and lifting equipment, iron weights are widely used as important counterweight components to balance tension and stabilize equipment operation. Traditional iron weights are usually one-piece cast iron structures with smooth metal surfaces on their outer surfaces and relatively simple structural designs.

[0003] A search revealed that the Chinese patent with publication number CN208698554U discloses an anti-collision composite weight. The key technical point is that by fixing rubber strips on the two arc edges of the outer circumference of the weight body, the weight body is reduced from being scrapped due to excessive weight loss or direct breakage caused by collisions during transportation.

[0004] However, in existing technologies, the connection between the protective components and the weight body is not stable enough, and they are prone to detachment after long-term use or when subjected to impact forces, leading to protection failure. Some designs have limited protection range, only protecting a local area of ​​the weight, resulting in insufficient protection. In addition, some protective structures are rigidly connected to the weight body, lacking buffer and shock absorption design. The impact force during a collision is transmitted to the weight body through the protective structure, affecting the protective effect and the durability of the structure. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0005] The aforementioned background technology addresses the problem that existing technologies only provide protection to a localized area of ​​the falling weight, resulting in insufficient protection.

[0006] The present invention discloses an anti-collision iron weight, comprising a weight body, a through groove provided on the weight body, an annular plate provided on the outer ring of the weight body, a rubber pad installed on the outer ring of the annular plate, and a fixing member provided between the annular plate and the weight body.

[0007] Furthermore, the upper part of the grinding wheel is provided with a groove, the cross-section of the annular plate is "L" shaped, the upper end of the annular plate is located inside the groove, and the annular plate covers the outer ring of the grinding wheel.

[0008] Furthermore, the fixing component includes a vertical rod, and multiple vertical rods are provided. The multiple vertical rods are evenly distributed at the lower end of the annular plate. One end of the vertical rod is fixedly connected to the annular plate. A through hole is provided on the weight body at the corresponding position of the vertical rod, and one end of the vertical rod passes through the through hole.

[0009] Furthermore, a damping ring is fitted onto the vertical rod, and the damping ring is installed on the inner wall of the through hole.

[0010] Furthermore, a placement groove is provided at the lower end of the grinding wheel, the placement groove is connected to the through hole, and a nut is provided inside the placement groove, the nut being threadedly connected to the vertical rod.

[0011] Furthermore, an installation groove is provided on the grinding wheel at the corresponding position of the rubber pad, the cross-section of the rubber pad is "I" shaped, the installation groove has the same shape as the rubber pad, and the inner ring of the rubber pad is installed inside the installation groove.

[0012] Furthermore, a second rubber pad is provided between the annular plate and the grinding wheel. The second rubber pad has an "L" shaped cross-section and is installed at the corner between the upper end face of the groove and the outer ring of the grinding wheel.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. The annular plate of this utility model is embedded in the groove on the upper part of the grinding wheel through its "L"-shaped structure, and multiple vertical rods are fixedly connected to the annular plate at one end and pass through the through hole on the grinding wheel. The vertical rods are then connected by threads using nuts placed in the groove, which strengthens the connection between the protective component and the grinding wheel from multiple aspects. At the same time, the rubber pad is installed in the corresponding mounting groove in a fitting "I" shape, which also helps to stabilize the connection and avoid the situation of the protective component falling off or the protection failing due to unstable connection, so that the protective function can play a stable role for a long time.

[0015] 2. The annular plate of this utility model covers the outer ring of the weight, and together with the "L"-shaped rubber pad II located at the corner of the groove and the outer ring of the weight, it can provide more comprehensive protection for the weight and overcome the problem of limited protection range in some existing designs. Furthermore, the damping ring on the vertical rod and the rubber pad II together form a buffer system, which can effectively buffer the impact force when it is hit, and prevent the impact force from being rigidly transmitted to the weight. This not only improves the protection effect, but also helps to extend the overall service life of the iron weight and enhance the structural durability. Attached Figure Description

[0022] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0023] Please see Figure 1 , Figure 2 , Figure 4 The present invention relates to an anti-collision iron weight, comprising a weight body 1, a through groove 2 on the weight body 1, the through groove 2 being U-shaped, an annular plate 4 on the outer ring of the weight body 1, a groove 3 on the upper part of the weight body 1, the annular plate 4 having an L-shaped cross-section, the upper end of the annular plate 4 being located inside the groove 3, the annular plate 4 covering the outer ring of the weight body 1, a rubber pad 9 installed on the outer ring of the annular plate 4, and an installation groove 10 on the weight body 1 at the corresponding position of the rubber pad 9, the rubber pad 9 having an I-shaped cross-section, and the installation groove 10 having the same shape as the rubber pad 9.

[0024] In this embodiment, a second rubber pad 11 is provided between the annular plate 4 and the weight body 1. The first rubber pad 9 and the second rubber pad 11 are made of nitrile rubber, which is not easily degraded due to contact with some impurities in the external environment. Moreover, its elasticity can effectively buffer during collision, ensuring good shock absorption effect and extending the service life of the entire anti-collision iron weight. The cross-section of the second rubber pad 11 is "L" shaped.

[0025] In this embodiment, the second rubber pad 11 is installed at the corner between the upper end face of the groove 3 and the outer ring of the weight body 1. The edge of the groove 3 is chamfered to make the second rubber pad 11 fit better during installation. In addition, it can avoid the problem of local damage to the weight body 1 due to stress concentration during daily use. The inner ring of the first rubber pad 9 is installed inside the mounting groove 10.

[0026] Combination Figure 2 , Figure 3 , Figure 4As shown, a fixing component is provided between the annular plate 4 and the grinding wheel 1. The fixing component includes a vertical rod 6. Multiple vertical rods 6 are provided and are evenly distributed at the lower end of the annular plate 4. One end of the vertical rod 6 is fixedly connected to the annular plate 4. A through hole 5 is provided on the grinding wheel 1 at the corresponding position of the vertical rod 6. One end of the vertical rod 6 passes through the through hole 5, and a damping ring 8 is fitted on the vertical rod 6.

[0027] In this embodiment, the damping ring 8 is installed on the inner wall of the through hole 5. The damping ring 8 is made of polyurethane polymer material with good friction and shock absorption properties. The lower end of the ball bearing 1 is provided with a placement groove 12, which is connected to the through hole 5. A nut 7 is provided on the inner side of the placement groove 12, and the nut 7 is threadedly connected to the vertical rod 6.

[0028] The implementation principle is as follows: During installation, firstly, the rubber pad 9 with an "I" shaped cut surface is installed inside the mounting groove 10 with the same shape, and the rubber pad 11 with an "L" shaped cut surface is installed at the corner between the upper end of the groove 3 and the outer ring of the weight body 1 to enhance the overall stability of the protective structure. Then, the upper end of the "L" shaped annular plate 4 is placed inside the groove 3 on the upper part of the weight body 1, so that the annular plate 4 covers the outer ring of the weight body 1. At the same time, one end of the vertical rod 6 passes through the through hole 5. Next, the nut 7 is installed at the lower end of the vertical rod 6, and the nut 7 is rotated to screw the nut 7 into the placement groove 12 to strengthen the connection between the annular plate 4 and the weight body 1.

[0029] During daily use or handling, when the iron weight is impacted, the annular plate 4 covers the outer ring of the weight body 1, and together with the rubber pad 2 11 located at the corner of the upper end of the groove 3 and the outer ring of the weight body 1, it provides more comprehensive protection for the weight body 1, avoiding the impact from directly affecting the surface of the weight body 1, and overcoming some of the problems of limited protection range in existing designs.

[0030] Furthermore, the damping ring 8 fitted on the vertical rod 6 and the rubber pad 11 installed on the upper end face of the groove 3 and at the corner of the outer ring of the weight body 1 together form a buffer system. When an impact force is generated by a collision, it can effectively buffer the impact force and prevent the impact force from being rigidly transmitted to the weight body 1. This not only improves the protective effect but also helps to extend the overall service life of the iron weight, enhances the structural durability, and ensures that the protective function can play a stable role for a long time, avoiding problems such as the detachment of protective parts or the failure of protection that affect the normal use of the iron weight.
