Description

Anti-winding electric power construction paying-off device for electric power construction Technical Field The utility model relates to the technical field of electric power paying-off, in particular to an anti-winding electric power construction paying-off device for electric power construction. Background The paying-off of the electric power construction is a key link in the electric power engineering construction, and relates to the procedures of paying-off, connection, wire tightening, fixing and the like of a lead, a ground wire or a cable. With the development of the power industry, the conventional mode of simply relying on manual paying-off is difficult to meet the current paying-off requirement of power construction, so that a plurality of paying-off devices special for the paying-off of the power construction are derived. For example, in the prior art, the patent publication No. CN119460873a provides an anti-winding electric power construction paying-off device for electric power construction, which is capable of preventing the electric wire from winding by retaining a ratchet gear and a ratchet block to perform unidirectional locking on the rotation direction of the electric wire coil, preventing the electric wire coil from reversely rotating in an inertial state due to sudden wire breakage during the paying-off process, resulting in loosening of the electric wire coil and winding of the electric wire. However, the above prior art still has the following drawbacks: (1) Because the height of the middle shaft barrel used for supporting the rotation of the wire coil is in a fixed state, the wire coil is required to be manually lifted and sleeved with the middle shaft barrel in the process of installing the wire coil, and the mode is very inconvenient, particularly when the paying-off distance is long and the wire coil is heavy, the manual installation is very inconvenient, and meanwhile, certain potential safety hazards exist. (2) After the wire coil is mounted on the center shaft barrel, the pressure of the wire coil is directly applied to the center shaft barrel, the wire coil is only supported by the first paying-off side plate positioned on one side of the wire coil, and the force applied by the wire coil to the first paying-off side plate is in a biased state, so that the first paying-off side plate is easy to topple over, and particularly the heavier the wire coil is, the greater the potential safety hazard is. Disclosure of utility model In view of the above, the present utility model provides an anti-wind power construction payoff device for power construction, which solves or at least alleviates the above-mentioned problems existing in the prior art.
