In addition, the traction rod 1 cannot be disconnected, so that the cable cannot be scraped. Therefore, the utility model provides a draw gear can protect the cable not receive wearing and tearing, not scraped brokenly to reduce the fault rate, improve the operation rate.
The connection of the drawbar 1 to the cable block will be described in detail below: for a multi-wheeled cable trolley, see fig. 3, the cable trolley has a connecting frame 4, which connecting frame 4 extends in the pulling direction. At the end of the connecting frame 4, a connecting piece is provided, which also extends in the pulling direction. The end of the connecting piece close to the end of the connecting frame 4 is an outer end, and the end far away from the end of the connecting frame 4 is an inner end. The other end of the traction rod 1 is hinged on the outer end of the connecting piece. The inner ends of the connecting pieces are connected to the connecting frame 4. The length and position of the connector depends on two factors: firstly, the traction rod 1 is ensured not to interfere with the connecting frame 4 of the cable pulley; secondly, it is ensured that the drawbar 1 does not interfere with the cable.
In particular, the connector may preferably be a U-shaped ring 3, the U-shaped ring 3 being placed horizontally. The inner end of the U-shaped ring 3 is bolted to the link 4.
In order to prevent the two adjacent cable blocks from colliding, a collision prevention device may be provided on an end surface of the connecting frame 4.
