Description

Technical Field

[0001] This utility model relates to the field of guiding equipment technology, and in particular to a wire rope guiding device for an offshore wind turbine tower hoist. Background Technology

[0002] The marine environment is complex and changeable. The impact of sea winds and waves, as well as factors such as humidity and salinity, place extremely high demands on the stability of offshore wind turbine tower hoists. During hoist operation, the wire rope, as a key traction component, directly affects the safety and efficiency of the hoist due to its guiding accuracy and stability.

[0003] Existing wire rope guiding devices have many shortcomings and are difficult to adapt to complex offshore working conditions. Most guiding devices can only provide guidance in one or a limited number of directions, failing to provide omnidirectional and precise guidance in the left-right and forward-backward directions. Under the irregular influence of sea winds, the wire rope is prone to deflection and swaying during elevator operation. Without multi-directional guidance, this will accelerate wire rope wear, shorten its service life, and even lead to safety accidents. Furthermore, these guiding devices are not flexible enough in structure and have poor adaptability to different specifications of wire ropes or changes in working conditions, seriously affecting the efficient and safe operation of offshore wind turbine tower elevators. Therefore, we propose a wire rope guiding device for offshore wind turbine tower elevators to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a wire rope guiding device for offshore wind turbine tower hoisting.

[0024] This application discloses a wire rope guiding device for an offshore wind turbine tower hoist.

[0025] Reference Figures 1-5 A wire rope guiding device for an offshore wind turbine tower hoist includes a fixed plate 1 fixedly installed on the offshore wind turbine tower hoist. Multiple connecting seats 201 are fixedly installed on the front side of the fixed plate 1. A longitudinal guide roller 202 is rotatably installed between corresponding connecting seats 201. A U-shaped frame 203 is detachably installed on the front and rear sides of the fixed plate 1. A longitudinal guide roller 204 adapted to the longitudinal guide roller 202 is rotatably installed inside the U-shaped frame 203. Two U-shaped plates 205 are slidably installed on the front side of the fixed plate 1. A rotating shaft is slidably installed on the inner walls of the front and rear sides of the U-shaped plates 205. A transverse guide wheel 206 is fixedly sleeved on the rotating shaft. A wire guide groove 207 for guiding the wire rope is opened on the transverse guide wheel 206. Reinforcing plates 5 are fixedly installed on both sides of the fixed plate 1. An adjustment mechanism is provided between the reinforcing plates 5 and the U-shaped plates 205.

[0026] In this embodiment, the adjustment mechanism includes a threaded hole 601, a drive screw 602, and a knob 603. The threaded hole 601 is formed on the reinforcing plate 5, and the drive screw 602 is threaded into the threaded hole 601. One end of the drive screw 602 is rotatably mounted on the U-shaped plate 205, and the other end of the drive screw 602 is fixedly mounted on the knob 603. A rotating groove is formed on one side of the U-shaped plate 205, and an annular groove is formed on the inner wall of the rotating groove. An annular seat is fixedly mounted on the drive screw 602, and the annular seat is rotatably connected to the annular groove. This design allows the operator to accurately adjust the position of the U-shaped plate 205 by simply rotating the knob 603, thereby conveniently changing the spacing of the transverse guide wheels 206 to adapt to the guiding requirements of different specifications of wire ropes.

[0027] In this embodiment, a guide hole 501 is provided on one side of the reinforcing plate 5, and a guide seat 502 is slidably installed in the guide hole 501, and the guide seat 502 is fixedly connected to the corresponding U-shaped plate 205. The cooperation between the guide hole 501 and the guide seat 502 provides stable support and precise guidance for the movement of the U-shaped plate 205, ensuring that the U-shaped plate 205 moves smoothly during adjustment and ensuring the stability of the transverse guide wheel 206 in guiding the wire rope.

[0028] In this embodiment, a positioning mechanism is provided between the U-shaped frame 203 and the fixed plate 1. Mounting seats 402 are fixedly installed on both sides of the U-shaped frame 203, and a fixing mechanism is provided between the mounting seats 402 and the fixed plate 1. The positioning mechanism includes a T-slot 301 and a T-shaped seat 302. Two T-slots 301 with open front sides are provided on the top and bottom of the fixed plate 1. A T-shaped seat 302 is fixedly installed on the rear side of the U-shaped frame 203, and the T-shaped seat 302 is adapted to the corresponding T-slot 301. This positioning mechanism can quickly and accurately determine the installation position of the U-shaped frame 203, facilitating subsequent fixing operations and improving installation efficiency. It also ensures the accurate relative position of the longitudinal guide roller 1 202 and the longitudinal guide roller 204, improving the accuracy of guiding the wire rope forward and backward.

This fixing method is simple to operate, provides a stable connection, and facilitates quick disassembly of the U-shaped frame 203 during maintenance and repair, ensuring convenient equipment maintenance.

[0030] In this embodiment, a sliding groove is provided on the front side of the fixed plate 1, and sliding seats are fixedly installed on the rear side of the U-shaped plates 205, with the sliding seats slidably connected to the corresponding sliding grooves. The cooperation between the sliding grooves and the sliding seats makes the U-shaped plates 205 easy to install and allows them to move flexibly under the action of the adjustment mechanism, which helps to achieve efficient adjustment of the left and right guiding function of the wire rope.

[0031] In this invention, a fixing plate 1 is installed on the elevator, so that the wire rope of the elevator is placed between two transverse guide rollers, and the rear side of the wire rope is in contact with the longitudinal guide roller 202. By rotating the knob 603 and the drive screw 602, under the action of the threaded hole 601, the drive screw 602 rotates and moves at the same time. The drive screw 602 can move the U-shaped plate 205 and the transverse guide rollers, so as to adjust the distance between the two transverse guide rollers. The wire groove 207 on the transverse guide roller can guide the wire rope in the left and right directions. The T-shaped seat 302 is installed in the T-shaped groove 301. At this time, the wire rope is between the longitudinal guide roller 202 and the longitudinal guide roller 204. By rotating the fixing bolt 404, it can be screwed into the bolt groove 401, so as to fix the U-shaped frame 203. Through the cooperation of the longitudinal guide roller 202 and the longitudinal guide roller 204, the wire rope can be guided in the front and back directions.
