Description

Technical Field

[0001] This utility model relates to the technical field of wind mast assist devices, specifically a wind mast lowering assist device. Background Technology

[0002] A wind mast lowering aid is a tool specifically designed to facilitate the lowering of wind masts, and is especially suitable for meteorological monitoring stations, marine monitoring stations, and other environments where equipment on wind masts needs to be frequently installed, maintained, or replaced.

[0003] When relocating wind masts, they need to be laid down for transport. Due to their height, wind masts need to be laid down with the help of a wind mast laying aid. However, the existing wind mast laying aids cannot lay down wind masts of different heights, resulting in low adaptability of the wind mast laying aids. Utility Model Content

[0004] The purpose of this invention is to provide a mast lowering aid to solve the problem mentioned in the background art that the existing mast lowering aids cannot lower masts of different heights, resulting in low adaptability of the mast lowering aids.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wind mast tilting aid includes a base frame, a movable rod rotatably connected to the surface of the base frame, a fixed block fixedly connected to the surface of the base frame, a first synchronous motor fixedly connected to the surface of the fixed block, a first lead screw fixedly connected to the output shaft of the first synchronous motor, a first square nut threadedly connected to the surface of the first lead screw, an adjusting rod rotatably connected to the surface of the first square nut, the end of the adjusting rod away from the first square nut rotatably connected to the surface of the movable rod, an adjusting mechanism provided on the surface of the movable rod, the adjusting mechanism including a second synchronous motor, the second synchronous motor fixedly connected to the surface of the movable rod, a second lead screw fixedly connected to the output shaft of the second synchronous motor, a second square nut threadedly connected to the surface of the second lead screw, a bidirectional screw fixedly connected to the surface of the second square nut, a threaded tube threadedly connected to the surface of the bidirectional screw, and a limit plate fixedly connected to the surface of the threaded tube.

[0006] Preferably, the first synchronous motor drives the first lead screw to rotate on the surface of the fixed block through its output shaft, and the first lead screw drives the first square nut to slide on the surface of the base frame through rotation.

[0007] Preferably, the base frame is U-shaped, and two sets of the first synchronous motor, the first lead screw, and the adjusting rod are provided, with the two sets of first synchronous motors driving the two sets of first lead screws to rotate synchronously.

[0008] Preferably, the movable rod is provided in two sets, and the first square nut drives the movable rod to rotate on the surface of the base frame through the adjusting rod during the sliding process.

[0009] Preferably, a guide groove is formed on the surface of the movable rod, and the second synchronous motor drives the second lead screw to rotate on the guide groove of the movable rod through the output shaft. The second lead screw drives the second square nut to slide on the guide groove of the movable rod through rotation.

[0010] Preferably, there are two sets of the second synchronous motor, the second lead screw, and the second square nut. The two sets of second synchronous motors drive the two sets of second lead screws to rotate synchronously on the movable rod, and the two sets of second square nuts simultaneously drive the bidirectional screw to slide on the surface of the movable rod.

[0011] Preferably, the bidirectional screw drives the threaded tube and the limiting plate to slide on the surface of the movable rod, and the limiting plate slides on the surface of the bidirectional screw through the threaded tube. Two sets of limiting plates are provided.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This wind mast lowering aid uses the output shaft of the second synchronous motor to drive the second lead screw to rotate. The rotation of the second lead screw causes the second square nut to slide on the guide groove of the movable rod. The second square nut causes the bidirectional screw to slide on the surface of the movable rod, thereby changing the contact height between the bidirectional screw and the wind mast. This allows the bidirectional screw to lower wind masts of different heights, improving the adaptability of the wind mast lowering aid.

[0014] 2. This wind mast lowering aid rotates a threaded tube on the surface of a bidirectional screw, which drives two sets of limiting discs to slide on the surface of the bidirectional screw. This causes the limiting discs to clamp the wind mast on both sides, preventing the wind mast from tilting during the lowering process and ensuring safety when lowering different wind masts.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides an embodiment of a wind mast tilting aid, comprising a base frame 1, a movable rod 11 rotatably connected to the surface of the base frame 1, a fixed block 2 fixedly connected to the surface of the base frame 1, a first synchronous motor 21 fixedly connected to the surface of the fixed block 2, a first lead screw 22 fixedly connected to the output shaft of the first synchronous motor 21, a first square nut 23 threadedly connected to the surface of the first lead screw 22, an adjusting rod 24 rotatably connected to the surface of the first square nut 23, the end of the adjusting rod 24 away from the first square nut 23 rotatably connected to the surface of the movable rod 11, and an adjusting mechanism provided on the surface of the movable rod 11. The device includes a second synchronous motor 3, which is fixedly connected to the surface of the movable rod 11. A second lead screw 31 is fixedly connected to the output shaft of the second synchronous motor 3. A second square nut 32 is threaded onto the surface of the second lead screw 31. A bidirectional screw 33 is fixedly connected to the surface of the second square nut 32. A threaded tube 34 is threaded onto the surface of the bidirectional screw 33. A limit plate 35 is fixedly connected to the surface of the threaded tube 34. This wind mast lowering aid adjusts the position of the bidirectional screw 33 on the movable rod 11, thereby enabling the bidirectional screw 33 to lower wind masts of different heights, improving the adaptability of the wind mast lowering aid.

[0023] The first synchronous motor 21 drives the first lead screw 22 to rotate on the surface of the fixed block 2 via its output shaft. The first lead screw 22 drives the first square nut 23 to slide on the surface of the base frame 1 through rotation. After rotation, the first lead screw 22 restricts the position of the first square nut 23 on the surface of the base frame 1. The base frame 1 is generally U-shaped. There are two sets of the first synchronous motor 21, the first lead screw 22, and the adjusting rod 24. The two sets of first synchronous motors 21 drive the two sets of first lead screws 22 to rotate synchronously. The synchronous rotation of the two sets of first lead screws 22 ensures the consistency of the sliding position of the two sets of first square nuts 23 on the base frame 1.

[0024] Two sets of movable rods 11 are provided. During the sliding process, the first square nut 23 drives the movable rod 11 to rotate on the surface of the base frame 1 via the adjusting rod 24. The movable rod 11 changes its angle on the surface of the base frame 1 by rotating, and the movable rod 11 can rotate 90 degrees on the base frame 1. Under the 90-degree rotation, the movable rod 11 can be laid down through the threaded tube 34. A guide groove is opened on the surface of the movable rod 11. The second synchronous motor 3 drives the second lead screw 31 to rotate on the guide groove of the movable rod 11 through the output shaft. The rotation of the second lead screw 31 drives the second square nut 32 to slide on the guide groove of the movable rod 11. After the second lead screw 31 stops rotating, it can restrict the position of the second square nut 32 in the guide groove of the movable rod 11.

[0025] Two sets of second synchronous motors 3, second lead screws 31, and second square nuts 32 are provided. The two sets of second synchronous motors 3 drive the two sets of second lead screws 31 to rotate synchronously on the movable rod 11, and the two sets of second square nuts 32 simultaneously drive the bidirectional screw 33 to slide on the surface of the movable rod 11. The bidirectional screw 33 supports one side of the wind rod, and its position changes, altering the support height for the wind rod. The bidirectional screw 33 drives the threaded tube 34 and the limiting plate 35 to slide on the surface of the movable rod 11. The limiting plate 35 slides on the surface of the bidirectional screw 33 through the threaded tube 34. Two sets of limiting plates 35 are provided, which clamp the wind rod, preventing it from shifting during lowering and ensuring the safety of the wind rod during lowering.

[0026] Working principle: The output shaft of the first synchronous motor 21 drives the first lead screw 22 to rotate. The first lead screw 22 drives the first square nut 23 to slide on the surface of the base frame 1. During the sliding process, the first square nut 23 drives the movable rod 11 to rotate through the adjusting rod 24. The movable rod 11 rotates so that the threaded tube 34 contacts one side of the wind rod. The threaded tube 34 rotates to slowly lower the wind rod. Due to the different heights of the wind rods, the output shaft of the second synchronous motor 3 drives the second lead screw 31 to rotate. The second lead screw 31 rotates so that the second square nut 32 slides on the guide groove of the movable rod 11. 2. The bidirectional screw 33 slides on the surface of the movable rod 11, thereby changing the contact height between the bidirectional screw 33 and the wind rod. This allows the bidirectional screw 33 to be lowered for wind rods of different heights, improving the adaptability of the wind rod lowering aid. When dealing with wind rods of different thicknesses, the threaded tube 34 is rotated on the surface of the bidirectional screw 33, which drives two sets of limiting discs 35 to slide on the surface of the bidirectional screw 33. This causes the limiting discs 35 to clamp the wind rod on both sides, preventing lateral tilting during the lowering process and ensuring safety when lowering different wind rods.
