Description

Technical Field

[0001] The utility model relates to the technical field of wire rope oil stain treatment, in particular to a device for collecting scrapped wire ropes of overhead crane equipment. Background Technique

[0002] In metallurgical enterprises, as a special equipment, overhead cranes play an irreplaceable role in daily production hoisting. In its main hoisting system, the lifting and lowering of the lifted object are mainly achieved by the contraction and lowering of the wire rope. Whether the operation period of the wire rope meets the requirements of safe use directly affects the safety state of the lifted object during actual hoisting. Therefore, when the main hoist wire rope of the overhead crane runs to a certain service life, an on-line replacement operation needs to be carried out. During the entire wire rope replacement operation process, there is an operation link when the waste wire rope is taken off the line. Since there is no waste wire rope collection device on the ground, a three-person cooperation operation method must be adopted. One person is responsible for collecting and bundling the waste wire rope in place, and the other two people are responsible for pulling the replaced waste wire rope in one direction.

[0003] The manual pulling operation method not only involves high labor intensity and low operation efficiency, but also because the length of the replaced waste wire rope is too long and there is different amounts of oil stain remaining on the surface. During the process of pulling the wire rope, the wire rope has been moving in an irregular form, which is extremely easy to cause the phenomenon of squeezing or bruising the operators. Moreover, the oil stain dripping on the ground will not only cause a certain degree of pollution to the ground environment, but also the on-site operators will continuously step on the oil stain when walking back and forth, and then accidents of operators falling due to the slipperiness of the ground oil stain will occur;

[0004] Therefore, we improve the existing equipment to avoid unnecessary problems caused by excessive oil stain adhering to the wire rope. Content of the Utility Model

[0033] The oil scraping mechanism 2 is arranged at the bottom of the working end of the vehicle body 3 and below the collection mechanism 1. It has a scraper 2.4 for scraping the oil stains on the steel wire rope before winding and collection. The scraper 2.4 is formed into a roughly square plate-like structure. The oil scraping mechanism 2 further includes a fixed frame 2.1, a fixed pulley 2.3, a scraper 2.4, a scraper pressing plate 2.5, a support shaft 2.6, a rotating cylinder 2.7, a torsion spring 2.8 and a support frame 2.9. One end of the fixed frame 2.1 is fixedly connected to the support leg 3.1 at the working end of the vehicle body 3, and the other end is hinged to the support frame 2.9 through a pin shaft 2.2. The fixed frame 2.1 is formed into a roughly square frame structure. A fixed pulley 2.3 is rotatably installed in the middle of the support frame 2.9. The support frame 2.9 is formed into a roughly square frame structure. An oil pan (not shown in the figure) is arranged below the fixed pulley 2.3 to collect the oil stains scraped off from the steel wire rope. The upper part of the support frame 2.9 is fixedly connected to the support shaft 2.6. A rotating cylinder 2.7 and two torsion springs 2.8 are sleeved on the support shaft 2.6.

The scraper 2.4 is made of rubber material, and a radian groove adapted to the steel wire rope is arranged in the middle to better fit the surface of the steel wire rope for scraping oil.

[0034] Four support legs 3.1 are arranged at the lower part of the vehicle body 3. The support legs 3.1 are formed into roughly square legs. A universal wheel 3.2 with a braking function is installed at the bottom of each support leg 3.1.

[0035] To facilitate the pushing of the vehicle body 3, a handle 3.3 is installed on the pushing end of the vehicle body 3.

[0036] The using process of the device for collecting scrapped steel wire ropes of this overhead crane equipment is as follows:

[0037] (1) Preparation stage: Place the device at the site where scrapped steel wire ropes need to be collected, ensure that the four support legs 3.1 of the vehicle body 3 are firmly supported on the ground, and fix the position of the device through the braking function of the universal wheels 3.2. Check whether the collection reel 1.1 of the collection mechanism 1 is in an empty state. If it is already equipped with an old steel wire rope, disassemble and replace it with a new collection reel 1.1 by turning the handle 1.2 by hand. Prepare an oil pan (not shown in the figure) and place it below the fixed pulley 2.3 to collect the scraped oil stains.

[0038] (2) Starting the equipment: The operator stands at the pushing end of the vehicle body 3 and easily pushes or pulls the entire device to a suitable working position through the handle 3.3. Then press the start button 1.7 on the control panel, and the motor 1.3 starts to work. It drives the transmission shaft 1.6 and the collecting reel 1.1 to rotate slowly through the speed reducer 1.4.

[0039] (3) Collecting the wire rope: Fix one end of the scrapped wire rope to be collected on the collecting reel 1.1. As the collecting reel 1.1 rotates, the wire rope is gradually wound and collected. When the wire rope passes through the fixed pulley 2.3, the oil scraping mechanism 2 starts to work. Under the support of the scraper pressing plate 2.5 and the elastic force of the torsion spring 2.8, the scraper 2.4 closely adheres to the surface of the wire rope to scrape off the oil stains on it. After the oil stains are scraped off, they fall into the oil pan below, realizing the separation of the oil stains from the wire rope.

[0040] (4) Monitoring and adjustment: The operator can interrupt the collection process at any time through the stop button 1.8 on the control panel for necessary inspections or adjustments. If it is necessary to change the collection direction (for example, when the wire rope needs to be wound reversely), the remote control change switch 1.9 can be used to control the forward and reverse rotation of the motor.

[0041] (5) Completing the collection: When the scrapped wire rope is completely collected on the collecting reel 1.1, press the stop button 1.8 to stop the motor. If it is necessary to replace the collecting reel or process the collected wire rope, the disassembly and replacement operations in step (1) can be repeated.

[0042] (6) Cleaning and maintenance: Clean the oil stains in the oil pan and handle them properly. Check whether the components of the oil scraping mechanism (2) are worn or loose, and replace or fasten them if necessary. Regularly maintain the entire device to ensure its long-term stable operation.

[0043] The advantages of the device for collecting scrapped wire ropes using this overhead crane equipment are as follows:

[0044] 1.
