detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.

As shown in Figure 1-2, a self-locking pay-off block includes a pay-off wheel 5, a hanging lug 1, a support rod 8 and a self-locking device; the support rod 8 includes a left support rod 8-1 and a right support rod 8-2; the left support rod 8-1 and the right support rod 8-2 are symmetrically arranged left and right, and are integrally connected; the upper end of the support rod 8 is connected with a hanging ear 1; the pay-off wheel 5 is rotatably arranged on the left support Between the rod 8-1 and the right support rod 8-2; the self-locking device includes a guide rod 6 and a block 7; one end of the guide rod 6 is connected to the outer surface of the left support rod 8-1, and the other end is obliquely upward The left support rod 8-1 extends externally; the stopper 7 is arranged on the inner side of the left support rod 8-1 and the position corresponding to the guide rod 6; the corresponding position of the stopper 7 on the left support rod 8-1 is provided with a locking port 4; the stopper 7. Connect the torsion spring 3.

The opening of the hanging lug 1 is provided with a baffle 2; after the hanging lug 1 is hung on the end of the insulator string, it can be automatically locked to prevent the self-locking pay-off block from falling; the pay-off wheel 5 passes through the bearing and the left support rod 8-1 and The right support rod 8-2 is connected; the rotation of the pay-off wheel 5 is more flexible through the bearing connection, and the pay-off process is more smooth; 5 Swipe up.

When in use, as shown in Figure 3, before hoisting the insulator string, the self-locking pay-off block can be connected to the end of the insulator string, the baffle plate 2 on the hanging ear 1 will be automatically locked, and the insulator string will be lifted to the cross arm of the tower. Connect the hanging point; spread the guide rope or ground wire to the straight pole tower, and the high-altitude workers will slowly lower the guide rope or ground wire, and guide the guide rope or ground wire to the lock through the guide rod 6. There are 4 stops; the block 7 is pushed away by the gravity of the guide rope or the ground wire itself, and the guide rope or the ground wire falls on the pay-off wheel 5 in the self-locking pay-off tackle; then the block 7 is on the Under the action of the torsion spring 3, it automatically returns to the original position, and the self-locking pay-off block is locked; then, the guide rope or the ground wire can be deployed by using the pay-off wheel 5, and self-locking during the deployment process The force on both sides of the pay-off block not only ensures that the block will not be deformed by the pressure of the guide rope or ground wire, but also ensures that the guide rope or ground wire will not jump out of the block during deployment.

The utility model can simplify the working process of deploying guide ropes or ground wires, improve work efficiency and reduce the working time of high-altitude workers. The utility model is simple in structure, convenient and practical, and has strong practicability.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present utility model shall be included in this utility model. within the scope of protection of utility models.
