Abstract
Description
Technical Field
[0001] This utility model belongs to the field of hoisting structure technology, and in particular relates to a lightweight steel structure hoisting device for railway locomotives. Background Technology
[0002] In the field of railway locomotive manufacturing and maintenance, lightweight steel structures, with their advantages of light weight and high strength, are widely used in core components such as locomotive body frames and bogie supports. Their hoisting operations are a crucial link in production assembly and troubleshooting. However, current lightweight steel structure hoisting devices for railway locomotives suffer from insufficient versatility in practical applications, making it difficult to adapt to the hoisting needs of components of different specifications, severely restricting operational efficiency and economy.
[0003] The existing lifting equipment generally has a fixed spacing between its load-bearing structures. Most lifting devices use integrated welding or multiple sets of bolts for rigid locking between the load-bearing rods and lifting beams, meaning the spacing cannot be adjusted after leaving the factory. Due to significant differences in the specifications of lightweight steel structures in railway locomotives, components of different models and locations vary considerably in size and weight. Fixed-spacing lifting devices cannot simultaneously meet these diverse lifting needs. To cover all specifications, multiple sets of lifting equipment with different spacings need to be purchased, increasing equipment procurement costs and storage space requirements. Furthermore, frequent device changes before operations lead to wasted time and low operational efficiency.
[0004] To address these issues, we provide a lightweight steel structure hoisting device for railway locomotives. Utility Model Content
[0005] The purpose of this utility model is to provide a lightweight steel structure hoisting device for railway locomotives. Through the action of the support shell, it can be locked in different positions on the adjusting rod through its groove part, and achieve preliminary positioning with the cooperation of the limiting rod and the adjusting hole. It can flexibly adjust the installation position on the adjusting rod according to the size, weight and other usage conditions of the lightweight steel structure of the railway locomotive to be hoisted, thereby changing the spacing of the bearing rods, adapting to the hoisting needs of steel structures of different specifications, improving the versatility of the device, and solving the problem that the spacing of existing bearing structures is generally fixed, and most hoisting devices use integrated welding or multiple sets of bolts to rigidly lock the bearing rods and hoisting beams, and their spacing cannot be adjusted after leaving the factory.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a lightweight steel structure hoisting device for railway locomotives, including a hoisting crossbeam, and the bottom of the hoisting crossbeam has adjustment grooves on both sides;
[0007] A connecting rod is fixed on both sides of the adjusting groove, and an adjusting rod is fixed at one end of the connecting rod;
[0008] The adjusting rod has several adjusting holes on its surface and several first threaded holes at its bottom.
[0009] The adjustment hole is rotatably connected to a limit rod. One end of the limit rod is fixed with an adjustment shell, and a support shell is fixed to one side of the adjustment shell. A second threaded hole is opened at the bottom of the support shell.
[0010] Both the support shell and the adjustment shell are fixed with a bearing rod on one side, and a protective plate is fixed to one end of the bearing rod.
[0011] The present invention is further configured such that: a fixing plate is movably connected to the bottom of the adjusting shell and the adjusting rod, and the surface of the fixing plate is provided with a third threaded hole and a fourth threaded hole;
[0012] The third threaded hole matches the first threaded hole, and the second threaded hole matches the fourth threaded hole.
[0013] The present invention is further configured such that: a positioning plate is fixed to the outer ring of the bearing rod, and a hoisting rope is sleeved between the positioning plate and the protective plate.
[0014] The present invention is further configured such that: a sliding groove is fixed at the top of the adjusting groove, and a reinforcing device is slidably connected inside the sliding groove;
[0015] The reinforcement includes a reinforcement plate.
[0016] The present invention is further configured such that: a slider is fixed to the top of the reinforcing plate, and the slider has a "T" shaped structure;
[0017] The slider is slidably connected to the groove.
[0018] The present invention is further configured such that: a through hole is opened on the surface of the reinforcing plate, and a spring is fixed at the top of the through hole;
[0019] A handle is fixed to one end of the spring, and a pull rod is fixed to one end of the handle;
[0020] One end of the pull rod is fixed with a threaded tube, and a limit plate is connected inside the threaded tube.
[0021] The present invention is further configured such that: a limiting hole is opened on the top of the protective plate, and the pull rod passes through the limiting hole.
[0022] This utility model has the following beneficial effects:
[0023] This utility model utilizes the support shell, which can be engaged at different positions on the adjusting rod through its grooved portion. Initial positioning is achieved through the cooperation of the limiting rod and the adjusting hole. The installation position on the adjusting rod can be flexibly adjusted according to the size, weight, and other usage conditions of the lightweight steel structure of the railway locomotive to be hoisted, thereby changing the spacing of the bearing rods and adapting to the hoisting needs of steel structures of different specifications, improving the versatility of the device. The inner wall of the support shell can fit against the top of the adjusting rod, and after being fixed to the bottom of the adjusting rod through the threaded hole of the fixing plate, it forms a stable connection structure with the adjusting rod, providing reliable support for the bearing rod and preventing the bearing rod from shifting or shaking due to force during hoisting, ensuring the safety and stability of the hoisting operation.
[0024] This utility model utilizes the action of a tie rod. One end of the tie rod can be inserted into the limiting hole of the protective plate. After being fixed with the limiting plate inside the threaded tube, it can work in conjunction with the spring to generate a continuous pulling force, pulling the protective plate and thus forming a stable constraint on the load-bearing rod. This effectively prevents the load-bearing rod from swaying or shifting due to force during hoisting operations, ensuring its stable working state. Through its stabilizing effect on the load-bearing rod, the tie rod can indirectly reduce the additional tension or displacement of the hoisting rope caused by the swaying of the load-bearing rod, reducing the risk of the hoisting rope loosening or breaking. At the same time, it ensures the accurate positioning of the steel structure to be hoisted during movement, improving the safety and reliability of the entire hoisting device operation.

[0037] For a specific implementation example, please refer to Implementation Example 1. Figure 1-6 This utility model is a lightweight steel structure hoisting device for railway locomotives, including a hoisting beam 1, with adjusting grooves 2 on both sides of the bottom of the hoisting beam 1; connecting rods 3 are fixed on both sides of the adjusting grooves 2, and adjusting rods 4 are fixed at one end of the connecting rods 3; the surface of the adjusting rods 4 has several adjusting holes 5, and the bottom of the adjusting rods 4 has several first threaded holes 6; a limiting rod 7 is rotatably connected inside the adjusting holes 5, and an adjusting shell 8 is fixed at one end of the limiting rod 7; a supporting shell 9 is fixed on one side of the adjusting shell 8, and a second threaded hole 10 is opened at the bottom of the supporting shell 9; a bearing rod 11 is fixed on one side of both the supporting shell 9 and the adjusting shell 8, and a protective plate 12 is fixed at one end of the bearing rod 11.
[0038] Specifically, a fixing plate 13 is movably connected to the bottom of the adjusting shell 8 and the adjusting rod 4. The surface of the fixing plate 13 has a third threaded hole 14 and a fourth threaded hole 15. The third threaded hole 14 matches the first threaded hole 6, and the second threaded hole 10 matches the fourth threaded hole 15.
[0039] Furthermore, a positioning plate 16 is fixed to the outer ring of the bearing rod 11, and a hoisting rope 17 is sleeved between the positioning plate 16 and the protective plate 12.
[0040] The operation process of this embodiment is as follows: When using this device, first hold the support shell 9 and align its groove with the adjusting rod 4. Slowly move the support shell 9 so that the groove of the support shell 9 is precisely locked in the appropriate position of the adjusting rod 4. At the same time, ensure that the limiting rod 7 at one end of the adjusting shell 8 is accurately locked into the corresponding adjusting hole 5 to achieve the initial positioning of the support shell 9 and prevent it from lateral displacement in subsequent operations. Using the limiting rod 7 as the rotation axis, slowly rotate the support shell 9 until the inner wall of the support shell 9 is completely in contact with the top of the adjusting rod 4, ensuring tight contact between the support shell 9 and the adjusting rod 4 and improving the support stability. Take the fixing plate 13 and place it on the support. At the bottom of the support shell 9, adjust the position of the fixing plate 13 so that the third threaded hole 14 on the fixing plate 13 is aligned with the first threaded hole 6 at the bottom of the adjusting rod 4, and the fourth threaded hole 15 is aligned with the second threaded hole 10 at the bottom of the support shell 9. Then, select the appropriate bolts and pass them through the aligned third threaded hole 14 and first threaded hole 6, and fourth threaded hole 15 and second threaded hole 10 in sequence. Tighten the bolts with a wrench or other tools to firmly fix the fixing plate 13 to the bottom of the support shell 9, completing the final fixation of the support shell 9 and ensuring that it will not loosen during hoisting. After the support shell 9 is fixed, take out the hoisting rope 17 and fix one end of it to a... In the area between the positioning plate 16 and the protective plate 12 on the outer ring of the side support rod 11, ensure that one end of the lifting rope 17 is firmly fixed and not easily detached. Tightly wrap the lifting rope 17 around the outside of the support rod 11, maintaining uniform tension during the wrapping process to avoid slackness or excessive tightness. After wrapping to a suitable length, fix the other end of the lifting rope 17 between the positioning plate 16 and the protective plate 12 on the other side support rod 11, completing the wrapping operation of the lifting rope 17. This ensures that the lifting rope 17 can stably support the weight of the steel structure. In this device, a support shell 9 is provided, which can be locked in different positions on the adjusting rod 4 through its groove. The initial positioning is achieved by the cooperation of the limiting rod 7 and the adjusting hole 5. The installation position on the adjusting rod 4 can be flexibly adjusted according to the size, weight and other usage conditions of the lightweight steel structure of the railway locomotive to be hoisted, thereby changing the spacing of the bearing rod 11 and adapting to the hoisting requirements of steel structures of different specifications, thus improving the versatility of the device. The inner wall of the support shell 9 can fit against the top of the adjusting rod 4. After being fixed to the bottom of the adjusting rod 4 by the cooperation of the fixing plate 13 through the threaded hole, it can form a stable connection structure with the adjusting rod 4, providing reliable support for the bearing rod 11 and preventing the bearing rod 11 from shifting or shaking due to force during hoisting, thus ensuring the safety and stability of the hoisting operation.
[0041] For a specific embodiment two, please refer to Figure 3-5Based on the first specific embodiment, a sliding groove 18 is fixed at the top of the adjusting groove 2, and a reinforcing device 19 is slidably connected inside the sliding groove 18; the reinforcing device 19 includes a reinforcing plate 20; a slider 21 is fixed at the top of the reinforcing plate 20, and the slider 21 has a "T" shaped structure; the slider 21 is slidably connected to the sliding groove 18.
[0042] Specifically, the reinforcing plate 20 has a through hole 22 on its surface, and a spring 23 is fixed to the top of the through hole 22; a handle 24 is fixed to one end of the spring 23, and a pull rod 25 is fixed to one end of the handle 24; a threaded tube 26 is fixed to one end of the pull rod 25, and a limit plate 27 is connected to the threaded tube 26 internally.
[0043] Furthermore, a limiting hole 28 is opened at the top of the protective plate 12, and the pull rod 25 passes through the limiting hole 28.
[0044] The operation process in this embodiment is as follows: After the hoisting rope 17 is wound, in order to further enhance the stability of the bearing rod 11 during the hoisting process, hold the handle 24 of the reinforcing device 19 and align the end of the pull rod 25 away from the handle 24 with the limiting hole 28 on the top of the protective plate 12. Slowly push the pull rod 25 so that one end of the pull rod 25 can be smoothly inserted into the limiting hole 28. Take the limiting plate 27 and align it with the end of the threaded tube 26. Rotate the limiting plate 27 so that the limiting plate 27 is gradually screwed into the threaded tube 26 until the limiting plate 27 and the threaded tube 26 are tightly connected without any signs of loosening. During the subsequent hoisting operation, the spring 23 at one end of the pull rod 25 will generate a continuous pulling force. This pulling force is transmitted to the protective plate 12 through the pull rod 25, pulling the protective plate 12 to maintain a stable state, thereby enabling the bearing rod 11 to maintain a stable state. When bearing the weight of the steel structure, the rod 11 is not prone to swaying or displacement, ensuring the safety and stability of the hoisting process. In this device, one end of the tie rod 25 can be inserted into the limiting hole 28 of the protective plate 12. After being fixed with the limiting plate 27 in the threaded tube 26, it can work together with the spring 23 to generate a continuous pulling force, pulling the protective plate 12, thereby forming a stable constraint on the bearing rod 11. This effectively prevents the bearing rod 11 from swaying or shifting due to force during hoisting operations, ensuring its stable working state. Through the stabilizing effect on the bearing rod 11, the tie rod 25 can indirectly reduce the additional tension or displacement of the hoisting rope 17 caused by the swaying of the bearing rod, reducing the risk of the hoisting rope 17 loosening or breaking. At the same time, it ensures the accurate positioning of the steel structure to be hoisted during the movement process, improving the safety and reliability of the entire hoisting device operation.
