Description

Rocker arm self-folding prevention device and method for rocker arm floor type holding pole based on combined spring
Technical Field
The invention belongs to the field of transmission line iron tower assembly construction, and particularly relates to a device and a method for preventing rocker arm self-furling of a rocker arm falling to the ground and holding pole based on a combined spring.

The assembly of the transmission line iron tower is an important link with large engineering quantity, high construction difficulty and multiple technical links in the construction of the power grid. The rocker arm floor pole can realize double-side simultaneous lifting work relative to the inner suspension pole, the construction efficiency is high, and the rocker arm pole upright post is directly supported on the ground, so that the structural stability and the safety are good, and the rocker arm floor pole is one of common and important construction equipment for the current tower assembly construction.
The basic structure of the existing rocker arm floor type derrick comprises a variable amplitude steel wire rope, a mast, a rocker arm, a derrick body and the like, and the rocker arm realizes variable amplitude through the movement of the variable amplitude steel wire rope. When the rocker arm falls to the ground and the pole body reaches a certain height, the length of the amplitude-variable steel wire rope is increased, so that the dead weight of the rocker arm is increased, and when the angle between the rocker arm and the mast is smaller, the rocker arm can be folded and self-locked due to the action of traction force of the amplitude-variable steel wire rope and wind load on the rocker arm. At present, a folding-preventing self-locking device is not installed on the rocker arm holding pole, and a manual or twisting mode is generally adopted for dragging below. From a review, zhang Weimin et al have designed a dual rocker arm boom arm anti-toppling jack that does not achieve the desired effect.
At present, a mode of manual or twisting and grinding to drag below is adopted to have potential safety hazards, so that safety accidents are easy to occur. Zhang Weimin et al, a double-rocker-arm holding-pole rocker-arm anti-overturning top support device is arranged at the top of a pole body, the spring elongation is small, the stroke is short, the spring force of the scheme is small, and the rocker arm is difficult to be sprung off smoothly. In addition, the friction force of the pushing plate on the rocker arm is large, the main material of the rocker arm is easy to damage, and the device cannot be popularized and applied due to the defects.
Some manufacturers have developed related device design work, but do not develop detailed theoretical research, and the problem of rocker arm furling and self-locking is not solved effectively.

A method for self-retracting a rocker arm anti-sway arm when the rocker arm is grounded based on a combination spring, characterized in that the method is based on the self-retracting device for self-retracting a rocker arm anti-sway arm when the rocker arm is grounded based on a combination spring according to any one of claims 1 to 5; comprising: 摇臂落地抱杆的摇臂（111）收拢后撞击支承杆（1），带动支承杆（1）与推杆（2）压向推杆压板（5），使组合弹簧受力压缩，将动能存储为弹性势能，反作用于摇臂（111），使摇臂（111）弹回，起到防摇臂收拢自锁的作用。The rocker arm (111) of the rocker arm landing holding rod is folded and hits the support rod (1), driving the support rod (1) and the push rod (2) to press against the push rod pressure plate (5), so that the combined spring is compressed and the kinetic energy is stored as elastic potential energy, which reacts to the rocker arm (111) and causes the rocker arm (111) to rebound, thereby playing the role of preventing the rocker arm from folding and self-locking.
