Description

Technical Field

[0001] This utility model relates to the field of lifting lug technology, and in particular to a lifting lug for a yellow phosphorus storage tank used for hoisting. Background Technology

[0002] In the hoisting operation of yellow phosphorus storage tanks, traditional lifting lugs are fixed to the tanks by welding. While this can meet conventional hoisting requirements to some extent, their non-adjustable position greatly limits the flexibility and applicability of the hoisting operation, making it difficult to adapt to different hoisting environments and equipment needs. Therefore, this utility model proposes a lifting lug for yellow phosphorus storage tanks. Utility Model Content

[0003] The purpose of this invention is to address the problem in the background art that the lifting lugs of traditional yellow phosphorus storage tanks are fixed by welding and their positions cannot be adjusted, which limits the flexibility and applicability of lifting operations and makes it difficult to meet the needs of different lifting environments and equipment. The invention proposes a lifting lug for yellow phosphorus storage tanks for lifting.

[0004] The technical solution of this utility model is as follows: a lifting lug for a yellow phosphorus storage tank, comprising a fixing ring fixed to the top of the storage tank; two sets of lifting lug bodies disposed above the fixing ring; a limiting component located on the fixing ring, the limiting component being used to limit the movement of the lifting lug bodies; an adjusting mechanism installed between the two sets of lifting lug bodies, the adjusting mechanism being used to adjust the position of the two sets of lifting lug bodies; and a locking mechanism disposed on the adjusting mechanism, the locking mechanism being used to lock the position of the lifting lug bodies.

[0005] Optionally, the limiting component includes sliders fixedly connected to both sides of the lifting lug body. A first limiting ring is provided on the opposite side of the two sets of lifting lug bodies and on the side of the two sets of lifting lug bodies that are far apart. The first limiting ring has an L-shaped cross-section, and the sliders slide in cooperation with the first limiting ring.

[0006] Optionally, the adjusting mechanism includes a fixed plate fixedly connected to the top of the storage tank. The fixed plate is located at the center of the fixed ring. A positioning rod is fixedly connected to the top of the fixed plate. A rotating block is rotatably connected to the positioning rod. Two sets of connecting rods are fixedly connected to the rotating block. The connecting rods pass through the two sets of lifting lug bodies and are fixedly connected to them.

[0007] Optionally, a second limiting ring is also fixedly connected to the top of the fixing ring. The second limiting ring has an L-shaped cross-section, and the connecting rod is located below the second limiting ring.

[0008] Optionally, the locking mechanism includes an annular groove formed on the top of the fixed plate, a first toothed groove formed in the annular groove, a pressure ring corresponding to the annular groove above the annular groove, and a second toothed groove corresponding to the first toothed groove formed at the bottom of the pressure ring.

[0009] Optionally, the locking mechanism further includes two sets of limiting frames disposed between the two sets of connecting rods. The two sets of limiting frames are L-shaped and symmetrically disposed on both sides of the rotating block. The bottom of each set of limiting frames is fixedly connected to a pressure ring. A sliding sleeve is fixedly connected between the two sets of limiting frames. A threaded rod is slidably connected in the sliding sleeve. The threaded rod is fixedly connected to the top of the positioning rod. A nut is threadedly connected to the threaded rod. The nut is disposed above the sliding sleeve.

[0010] Optionally, it also includes two sets of elastic support components, which are respectively disposed below the two sets of limiting frames. The elastic support components are used to lift the limiting frames and separate the second tooth groove from the first tooth groove.

[0011] Optionally, the elastic support assembly includes a cavity formed in the rotating block, a sliding plate slidably connected in the cavity, a support rod fixedly connected to the top of the sliding plate, the support rod passing through the top of the rotating block and fixedly connected to a contact plate, and a spring disposed in the cavity, the spring being disposed below the sliding plate.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] This utility model utilizes the cooperation of a spring and a nut in an elastic support assembly. Rotating the nut upwards separates the pressure ring from the annular groove, releasing the restriction on the connecting rod. The rotating block drives the lifting lug body to move around the positioning rod in a circular motion to achieve position adjustment. After adjustment, rotating the nut downwards engages the second tooth groove with the first tooth groove, and the connecting rod is locked by the limit frame, achieving precise fixation of the lifting lug body position. The operation process is simple and efficient, greatly improving the flexibility of lifting operations.

[0014] Furthermore, by forming a dual force transmission path through the slider and the first limiting ring, and the connecting rod and the second limiting ring, the force borne by the lifting lug body is transmitted to the fixed ring, dispersing the weight of the storage tank and avoiding overload of a single structure; at the same time, the locking mechanism ensures that the position of the lifting lug body will not loosen during the hoisting process through a dual fixing method of toothed engagement and nut locking, effectively improving the reliability of the device and the safety of operation;

[0015] In summary, this utility model effectively improves the adaptability of hoisting operations to different environments and equipment, and solves the problem of insufficient flexibility of traditional welded fixed lifting lugs. Attached Figure Description

[0030] Example

[0031] like Figures 1 to 3 As shown, the present invention proposes a lifting lug for a yellow phosphorus storage tank, comprising a fixing ring 1 fixed to the top of the storage tank by welding. It also includes two sets of lifting lug bodies 2 disposed above the fixing ring 1.

[0032] Furthermore, the aforementioned lifting lug also includes a limiting component 3 located on the fixed ring 1. The limiting component 3 is used to limit the movement of the lifting lug body 2. The limiting component 3 includes sliders 31 fixedly connected to both sides of the lifting lug body 2. A first limiting ring 32 is provided on the opposite side of the two sets of lifting lug bodies 2 and on the side of the two sets of lifting lug bodies 2 that are far apart. The first limiting ring 32 has an L-shaped cross-section. The sliders 31 and the first limiting ring 32 slide together. The sliders 31 and the first limiting ring 32 limit the movement of the lifting lug body 2. At the same time, when the lifting lug body 2 is lifted, the force is transmitted to the fixed ring 1 through the sliders 31 and the first limiting ring 32, thereby realizing the lifting of the storage tank.

[0033] For further details, please refer to Figure 1 and Figure 4The aforementioned lifting lugs also include an adjustment mechanism 4 installed between the two sets of lifting lug bodies 2. The adjustment mechanism 4 is used to adjust the position of the two sets of lifting lug bodies 2. The adjustment mechanism 4 includes a fixed plate 41 fixedly connected to the top of the storage tank. The fixed plate 41 is located at the center of the fixed ring 1 and is fixed by welding. A positioning rod 42 is fixedly connected to the top of the fixed plate 41 and is fixed at the center of the fixed plate 41. A rotating block 43 is rotatably connected to the positioning rod 42, and the positioning rod 42 keeps the rotating block 43 in its original position. Two sets of connecting rods 44 are fixedly connected to the rotating block 43. The connecting rods 44, like the rotating block 43, rotate around the positioning rod 42. The connecting rods 44 pass through the two sets of lifting lug bodies 2 and are fixedly connected to them. Thus, when the connecting rods 44 rotate, they drive the lifting lug bodies 2 to perform circular motion, which facilitates the adjustment of the position of the lifting lug bodies 2. A second limiting ring 45 is also fixedly connected to the top of the fixed ring 1. The second limiting ring 45 has an L-shaped cross-section. The connecting rod 44 is located below the second limiting ring 45. Thus, when the lifting lug body 2 is lifted, the lifting lug body 2 simultaneously drives the connecting rod 44 to move upward, and cooperates with the second limiting ring 45 to transmit the force to the fixed ring 1. Together with the slider 31 and the first limiting ring 32, it shares the weight of the storage tank, thereby improving the reliability of the device.

[0034] Specifically, such as Figure 1 and Figure 4 As shown, the aforementioned lifting lug also includes a locking mechanism 5 disposed on the adjusting mechanism 4. The locking mechanism 5 is used to lock the position of the lifting lug body 2. The locking mechanism 5 includes an annular groove 51 opened on the top of the fixed plate 41. A first toothed groove 52 is opened in the annular groove 51. A pressure ring 53 corresponding to it is disposed above the annular groove 51. A second toothed groove 54 corresponding to the first toothed groove 52 is opened at the bottom of the pressure ring 53. Thus, after the pressure ring 53 moves into the annular groove 51, the second toothed groove 54 is locked in the position of the first toothed groove 52, thereby preventing the pressure ring 53 from rotating and ensuring that the positions of the two sets of lifting lug bodies 2 are fixed. The locking mechanism 5 also includes two sets of limiting frames 55 disposed between the two sets of connecting rods 44. The two sets of limiting frames 55 are L-shaped and symmetrically arranged on both sides of the rotating block 43. The bottom of each set of limiting frames 55 is fixedly connected to the pressure ring 53, so that the pressure ring 53 will not rotate after the second tooth groove 54 is engaged in the first tooth groove 52, thus ensuring that the position of the limiting frame 55 is fixed. Consequently, the connecting rods 44 on both sides of the limiting frame 55 are limited by the limiting frame 55 and will not rotate. A sliding sleeve 56 is fixedly connected between the two sets of limiting frames 55. When the sliding sleeve 56 moves up and down, it drives the pressure ring 53 to move synchronously through the limiting frame 55. A threaded rod 57 is slidably connected in the sliding sleeve 56. The threaded rod 57 is fixedly connected to the top of the positioning rod 42, and the position of the threaded rod 57 is fixed. A nut 58 is threaded onto the threaded rod 57. The nut 58 is positioned above the sliding sleeve 56, so that when the nut 58 is rotated, it moves up and down, thereby moving downward and driving the sliding sleeve 56 downward, so that the pressure ring 53 approaches the annular groove 51 and gets stuck there.

[0035] Furthermore, the aforementioned lifting lug also includes two sets of elastic support components 6, which are respectively disposed below the two sets of limiting frames 55. The elastic support components 6 are used to lift the limiting frames 55 and separate the second toothed groove 54 from the first toothed groove 52, facilitating the rotation of the pressure ring 53 and thus facilitating the adjustment of the position of the lifting lug body 2. The elastic support component 6 includes a cavity 61 opened in the rotating block 43, a sliding plate 62 slidably connected in the cavity 61, a support rod 63 fixedly connected to the top of the sliding plate 62, the support rod 63 passing through the top of the rotating block 43 and fixedly connected to a contact plate 64, and a spring 65 disposed in the cavity 61, which is disposed below the sliding plate 62. The spring 65 lifts the limiting frame 55 by its elastic force, and when the nut 58 is in the high position, it lifts the limiting frame 55, thereby causing the pressure ring 53 to move away from the annular groove 51, so that the pressure ring 53 can rotate, facilitating the connecting rod 44 to drive the lifting lug body 2 to rotate and adjust its position. At the same time, when the nut 58 rotates and moves downward, it drives the limit frame 55 to move downward and compresses the spring 65 to accumulate elastic force.

[0036] In this embodiment, when it is necessary to adjust the position of the lifting lug body 2, firstly, rotate the nut 58 upward to disengage it from the sliding sleeve 56. During the upward movement of the nut 58, the sliding sleeve 56 is no longer subjected to downward pressure. At this time, the spring 65 in the elastic support assembly 6 takes effect. The elastic force of the spring 65 pushes the sliding plate 62 upward, and the sliding plate 62 drives the support rod 63 and the contact plate 64 to rise. The contact plate 64 lifts the limiting frame 55, thereby causing the pressure ring 53 to move away from the annular groove 51, and the second tooth groove 54 to separate from the first tooth groove 52. The pressure ring 53 is no longer restricted by the slot and can rotate freely. The rotating block 43 is kept in place by the positioning rod 42. When the rotating block 43 rotates, it drives the connecting rod 44, which is fixedly connected to it, to rotate. The connecting rod 44 passes through and is fixedly connected to the lifting lug body 2, thereby driving the lifting lug body 2 to perform circumferential motion around the positioning rod 42, realizing the adjustment of the position of the lifting lug body 2.

[0037] After the lifting lug body 2 is positioned correctly, rotate the nut 58 downwards. The nut 58 moves downwards along the threaded rod 57, pushing the sliding sleeve 56 downwards. The sliding sleeve 56, through the limiting frame 55, drives the pressure ring 53 downwards. As the pressure ring 53 gradually approaches the annular groove 51, when the second tooth groove 54 at the bottom of the pressure ring 53 corresponds to and engages with the first tooth groove 52 in the annular groove 51, the pressure ring 53 is locked and cannot rotate. Since the limiting frame 55 is fixedly connected to the pressure ring 53, the limiting frame 55 is also fixed, thereby restricting the rotation of the connecting rods 44 on both sides, thus reliably locking the position of the lifting lug body 2.

[0038] During the hoisting process, when the lifting lug body 2 is lifted, the slider 31 slides in conjunction with the first limiting ring 32, transmitting the hoisting force to the fixed ring 1. Simultaneously, the lifting lug body 2 drives the connecting rod 44 to move upward, and the connecting rod 44, in conjunction with the second limiting ring 45, also transmits the force to the fixed ring 1. The slider 31, the first limiting ring 32, the connecting rod 44, and the second limiting ring 45 share the weight of the storage tank, ensuring effective force transmission during hoisting. Furthermore, due to the weight of the storage tank itself, the friction between the slider 31 and the first limiting ring 32, the connecting rod 44, and the second limiting ring 45 is also relatively large, preventing the storage tank from rotating during hoisting and ensuring the safety and stability of the hoisting operation.

[0039] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
