Description

Technical Field

[0001] The utility model relates to the technical field of anchor cable processing, in particular to a steel strand pay-off device used for processing anchor cables in foundation pits and slopes. Background Art

[0002] Anchor cable is a commonly used support structure in foundation pit and slope engineering. The anchor cable material is usually steel strand, which is made of several steel wires with a diameter of about 5-8mm. The steel wire is generally purchased in a whole coil. After being transported to the construction site, it is processed and cut according to the designed length, and then several steel wires are twisted into anchor cable steel strand. When cutting and processing the steel strand on the construction site, the packaging on the whole coil of material needs to be removed and the steel wire is directly pulled out of the coil. After removal, the steel strand loses its restraint and becomes loose. As the anchor cable loosens, the upper anchor cable will squeeze the lower anchor cable, which is not conducive to pulling the anchor cable out of the coil, making it difficult to withdraw the anchor cable. The next time the anchor cable is processed, the squeezed anchor cable can only be cut off by fire welding, resulting in material waste; and each time the anchor cable is cut, multiple people are required to assist in the operation, which increases the labor intensity of the workers.

[0003] To solve the above problems, a Chinese patent with authorization announcement number CN 209936447 U discloses a device for processing anchor cables, including a chassis, a first support column, a second support column and a roller device, one end of the first support column and the second support column are connected to the chassis, the roller device is located between the two support columns, and includes a roller body, a telescopic connection, a first rotating shaft and a second rotating shaft, the roller body is rotatably installed between the two support columns through the first rotating shaft and the second rotating shaft, the two ends of the roller body are respectively connected to the first rotating shaft and the second rotating shaft through the telescopic connection, and the first support column and the second support column are both provided with locking members for locking or loosening the first rotating shaft and the second rotating shaft. When processing the anchor cable, this patent installs the wire reel on the drum body, pulls the anchor cable head forward, and drives the drum to rotate. When the person in front pulls the anchor cable to the cutting machine for cutting according to the designed size, the first rotating shaft and the second rotating shaft are locked by the locking member, and then the anchor cable is cut. When withdrawing the steel strand, it starts from the outside of the entire reel of material. It is easy to operate and convenient to process the anchor cable. However, the structure of the device is relatively complicated, the entire device takes up more space, and is not easy to carry. In addition, the steel strand of the device is still wound from the outer ring, and the removed steel strand will still become loose due to the loss of restraint. Summary of the invention
