Description

Technical Field

[0001] This utility model relates to the field of tower crane technology, and in particular to a modular tower crane wire rope coiling device that allows for easy loading and unloading. Background Technology

[0002] Hoisting wire rope is a crucial component of tower cranes. During operation, scraping or slipping of the hoisting wire rope can easily cause localized damage. Due to the special nature of wire rope, the entire rope usually needs to be replaced. While the old wire rope can be used on shorter tower cranes after cutting off the damaged portion, it is difficult to reassemble and store, leading to rapid corrosion and making it unusable. Since wire rope on tower cranes is mostly disposable, it results in significant waste, high cost, and poor economic efficiency and practicality. Therefore, designing a modular tower crane wire rope reeling device that allows for easy loading and unloading effectively solves the problem of reassembling old wire rope into drums for storage, significantly improving the practicality and economy of wire rope applications. Utility Model Content

[0003] The purpose of this utility model is to provide a modular tower crane wire rope coiling device that allows for easy loading and unloading, in order to solve the problems of existing wire ropes being difficult to re-coil and store, resulting in rapid corrosion of old wire ropes and difficulty in reinstalling them on the tower crane, making them unusable again; the application of wire ropes on tower cranes is mostly disposable, resulting in serious waste of wire ropes, high wire rope prices, and poor economy and practicality.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a modular tower crane wire rope coiling device for convenient loading and unloading, comprising a bottom support, a transmission bracket, an auxiliary support, a first support shaft, a second support shaft, a locking nut, a roller, a first square frame, a motor, a first coupling, an adjusting bracket, an adjusting screw, a connecting block, a sliding table, a mounting frame, a rope-laying pulley block, a second square frame, an adjusting motor, a second coupling, and a guide rod. The transmission bracket and auxiliary support are symmetrically arranged on one side of the top of the bottom support, and the transmission bracket and auxiliary support are respectively rotatably connected... The device has a first support shaft and a second support shaft. Both the first and second support shafts are threadedly connected to locking nuts, which are connected to both ends of the roller and pressed tightly against the roller. On the other side of the top of the bottom support, there are symmetrical adjustment brackets. The adjustment brackets are rotatably connected to the adjustment screw through bearings. The adjustment screw is equipped with a connecting block, which is connected to the adjustment screw through an internally embedded ball nut. The connecting block is embedded in the sliding table. The top of the sliding table is equipped with a mounting frame, and the mounting frame is equipped with a rope pulley system.

[0005] As a further technical solution of this utility model, a first square frame is provided on one side of the transmission bracket, and an electric motor is fixedly installed on one side of the first square frame.

[0006] As a further technical solution of this utility model, the output end of the motor is fixedly connected to a first coupling through the first square frame, and the first coupling is connected to the first support shaft.

[0007] As a further technical solution of this utility model, a second square frame is provided on one side of the adjustment bracket.

[0008] As a further technical solution of this utility model, an adjustment motor is fixedly installed on one side of the second square frame, and the output end of the adjustment motor is fixedly connected to a second coupling through the second square frame.

[0009] As a further technical solution of this utility model, the second coupling is connected to the adjusting screw.

[0010] As a further technical solution of this utility model, guide rods are symmetrically arranged between the adjustment brackets, and the guide rods are slidably connected to the sliding table.

[0011] This utility model provides a modular tower crane wire rope coiling device with convenient loading and unloading. Its advantages are as follows: A first support shaft and a second support shaft are supported by a transmission bracket and an auxiliary support, respectively. Locking nuts on the first and second support shafts are threaded onto both ends of the drum, pressing the drum tightly between the first and second support shafts to form a detachable drum structure. This facilitates easy assembly and disassembly and is highly efficient. During use, the old wire rope is passed through the rope-laying pulley assembly and fixed to the detachable drum. Starting the motor and adjusting motor automatically lays the rope. During the laying process, the rope-laying pulley assembly provides a certain pre-tension, resulting in better rope laying and greatly improving the practicality and economy of tower crane wire rope applications. Simultaneously, during the laying process, the adjusting motor drives the adjusting screw to rotate. The adjustment screw, in conjunction with the ball bearing nut embedded inside the connecting block, drives the sliding table and the rope-laying pulley assembly to reciprocate along the guide rod, making the rope laying more uniform.
