Adjustable fixing hoop for pole tower

Abstract

The invention discloses an adjustable fixing hoop for a pole tower, and relates to the technical field of pole tower fixing. The adjustable fixing hoop comprises a front end hoop, a rear end hoop, a limiting plate and a nylon binding belt, wherein a hinge supporting column is installed at one end of the front end hoop; a wire inlet and a wire outlet are formed in the outer wall of the front end hoop; one end of the rear end hoop is hinged to the hinge supporting column; one end of a locking screw rod penetrates through the front end hoop and is in threaded connection with the other end of the rear end hoop; the lower end of the limiting plate is uniformly fixed to the lower edge of the front end hoop and the lower edge of the rear end hoop through torsion springs; a wire penetrating hole is formed in the upper end of the side surface of the limiting plate; and one end of the nylon binding belt sequentially penetrates through the wire inlet, the wire penetrating hole of the limiting plate and the wire outlet. According to the adjustable fixing hoop, the front end hoop and the rear end hoop are fixed to the pole tower, the nylon binding belt enables the limiting plate to be tightly attached to the pole tower, meanwhile, the two ends of the nylon binding belt are fixed in a locking type binding belt head, a tension sensor is used for detecting the looseness of the nylon binding belt, and the firmness of the hoop during fixing is improved.

Description

technical field [0001] The invention belongs to the technical field of tower fixing, and in particular relates to an adjustable fixing hoop for a tower. Background technique [0002] The hoop is a common connecting part used to fix the components such as towers, cross arms and tie rods. It is an indispensable fastener in power line engineering. However, in recent years, with the application technology of towers and cross arms The advantages are gradually reflected, and the pole tower has become an ideal substitute for traditional pole tower products. If the traditional hoop connection method is used to connect the fixed pole tower, cross arm and tie rod and other components, the hoop is prone to relative displacement when the wire is installed or broken. And deflection, lead to changes in electrical structure design, resulting in changes in discharge gaps, corresponding changes in electrical safety distance, which greatly threatens the safe operation of transmission lines, a...

[0002] The hoop is a common connecting part used to fix the components such as towers, cross arms and tie rods. It is an indispensable fastener in power line engineering. However, in recent years, with the application technology of towers and cross arms The advantages are gradually reflected, and the pole tower has become an ideal substitute for traditional pole tower products. If the traditional hoop connection method is used to connect the fixed pole tower, cross arm and tie rod and other components, the hoop is prone to relative displacement when the wire is installed or broken. And deflection, lead to changes in electrical structure design, resulting in changes in discharge gaps, corresponding changes in electrical safety distance, which greatly threatens the safe operation of transmission lines, and many hoops do not have a slack warning function during use , and even some hoops cannot realize the adjustment function of the contact area during use, which affects the safety of hoop use
