Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of anti-falling hanging rings, and in particular relates to an anti-falling hanging ring for an iron tower and an installation method thereof. Background Art
[0002] The transmission tower is a tower-shaped building used for power transmission. Its structural characteristics are that all types of towers belong to the space frame structure. The rods are mainly composed of a single equilateral angle steel or a combined angle steel. The materials generally use Q235 (A3F) and Q345 (16Mn). The rods are connected by rough bolts, which are connected by shear force. The whole tower is composed of angle steel, connecting steel plates and bolts. Individual parts such as the tower foot are welded into a combination of several steel plates. This structure makes hot-dip galvanizing, transportation and construction and erection extremely convenient. For towers with a height of less than 60m, foot nails are set on one of the main materials of the tower to facilitate construction workers to climb the tower. According to the number of circuits, there are single-circuit transmission towers and double-circuit transmission towers. Single-circuit transmission towers are towers with one circuit. Double-circuit transmission towers are towers with two circuits. Generally, enterprises with high requirements for power supply reliability, or important regional substations, mostly use dual-circuit power supply, so that when one power supply fails for some reason, the other power supply can continue to supply power; while small and medium-sized users with low requirements for power supply reliability often use single power supply. The anti-fall hanging ring for iron tower refers to a safety device that protects the safety of workers when they climb the iron tower. This hanging ring is usually used for high-altitude operations to prevent workers or equipment from accidentally falling, and plays a protective role. By hanging safety belts or safety ropes on these hanging rings, the safety of workers working at heights can be ensured. The existing anti-fall hanging ring is only a ring hook. During the climbing process, the workers will hang the ring hook on the foot nails of the iron tower one by one as they climb. It does not have the function of clamping the ring hook and the foot nail, so a new type of anti-fall hanging ring for iron tower is needed. Summary of the invention
[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a tower anti-fall hanging ring and an installation method, thereby solving the problems in the above-mentioned background technology.

The setting of the docking part facilitates the connection between the anti-fall hanging ring and the operator's safety belt, which is simple, convenient and fast to operate. The automatic closing component is set up to block the opening position of the hook part. When the automatic closing component is opened, it is easy to hang the anti-fall hanging ring on the foot nail. When the automatic closing component is closed, the foot nail can be firmly blocked inside the hook part in cooperation with the automatic locking component, thereby improving safety.

When in use, the second locking member cooperates with the first locking member to fix the foot nail inside the hook portion. When the anti-fall hanging ring is hung on the foot nail, the foot nail is located between the left clamp plate and the right clamp plate. At this time, the first spring and the second spring are compressed. Under the action of the first spring and the second spring restoring force, the left clamp plate and the right clamp plate clamp and fix the foot nail from both sides of the foot nail respectively. The structure is simple and the effect is good. When the operator pushes the hand push part upward, the hand push part moves upward and is stored in the storage side hole. At this time, the inner spring is compressed, and the lower end of the guide rod is pulled out from the lower closing seat, so that a gap appears between the upper closing seat and the lower closing seat. At this time, the opening of the hook portion is opened, which is conducive to quickly hanging the foot nail into the hook portion.

Under the action of the restoring force of the inner spring, the guide rod moves downward, and the guide convex strip of the guide rod moves downward along the upper inner groove into the lower inner groove. The gap between the upper closed seat and the lower closed seat is blocked. At this time, the foot nail is located between the guide rod, the left clamping plate, and the right clamping plate. At the same time, the first spring and the second spring are in a compressed state, so that the foot nail is firmly fixed in the hook part, the connection is stable, and it is not easy to fall off. The setting of the arc-shaped notch and the anti-slip convex strip makes it easier and more labor-saving for the operator to push the hand push part. The inner fixing of the hook part is provided with a reinforcing rib. The reinforcing rib is used for the hook part to be hooked to the foot nail of the iron tower, so that the foot nail is between the first locking member and the second locking member, and the foot nail is clamped and fixed by the first locking member and the second locking member. The strength of the hook part is enhanced by the setting of the reinforcing rib. BRIEF DESCRIPTION OF THE DRAWINGS
