Description

Technical Field

[0001] The invention belongs to the technical field of tower climbing operations, and in particular relates to a safety rope fixing device for tower climbing operations. Background Art

[0002] Tower climbing is one of the most important and common jobs in the power industry, mainly involving the maintenance, inspection, and installation of transmission lines. The operation process includes: 1. Preparation: Confirm the operation tasks and operation plan. Conduct safety briefings to clarify the operation content, safety measures, and emergency measures. Check all equipment and tools to ensure that they are intact. 2. Site assessment: Check the weather conditions to ensure that it is suitable for the operation. Assess the terrain and surrounding environment of the operation site to ensure safety. 3. Tower climbing: Wear personal protective equipment. Use foot buckles and safety ropes to climb to the operation location step by step. During the climbing process, ensure that each step is stable and reliable. 4. Operation: After arriving at the operation location, conduct a preliminary inspection to confirm the status of the equipment. Perform maintenance, inspection, or installation work according to the operation plan. Keep in touch with the ground personnel and report the progress of the operation in a timely manner. 5. Evacuation: After the operation is completed, clean up the operation site to ensure that there are no leftovers. Evacuate the tower in the correct order to ensure safety. The transmission line is realized by using a transformer to step up the voltage of the electric energy generated by the generator, and then connecting it to the transmission line through control equipment such as circuit breakers. It is usually composed of line towers, conductors, insulators, line hardware, guy wires, tower foundations, grounding devices, etc., and is erected above the ground. In order to ensure the normal use of the line towers, workers are required to climb the towers for regular maintenance. In order to ensure the personal safety of the workers, the backup safety rope needs to be pre-installed before climbing the tower for maintenance. However, the installation of the backup safety rope is also achieved by manual climbing of the tower, which not only has high labor intensity and low safety factor, but also reduces the efficiency of the overall installation operation to a certain extent. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a safety rope fixing device for tower climbing operations, which solves the problems in the above-mentioned background technology.

When in use, the operator holds the connecting ring and lifts the auxiliary handle upward. The lifting of the auxiliary handle drives the inner ends of the first L-shaped connecting rod and the second L-shaped connecting rod to retract outward. At this time, the cavity inside the cylinder is opened, and the lower end of the safety rope is inserted into the inside of the cylinder. After the operator releases the connecting ring, the auxiliary handle automatically drops downward under the action of the counterweight, so that the inner ends of the first L-shaped connecting rod and the second L-shaped connecting rod are clamped with the side wall of the safety rope. The connecting ring is used to dock with the hook of the safety belt on the operator. During the operator's climbing process, the safety rope fixing device always moves upward with the operator. If an accidental fall occurs, the safety belt hook on the operator will pull the connecting ring downward, so that the inner ends of the first L-shaped connecting rod and the second L-shaped connecting rod lock the safety rope inside the cylinder to prevent the operator from falling. Through the setting of the second fixing component, if the first L-shaped connecting rod and the second L-shaped connecting rod cannot be completely locked during the falling process, the operator can manually operate the second fixing component for a second lock, providing further emergency safety protection.

When in use, in the default state, the first spring is compressed, the transverse bolt shrinks inside the transverse cylinder, and the external rod is used to pull the transverse bolt to shrink it inside the transverse cylinder. When in use, it is triggered by the operator, and under the action of the restoring force of the first spring, the transverse bolt rushes out of the transverse cylinder, and the tip portion of the transverse bolt squeezes the safety rope inside the cylinder and inserts into the blocking opening to achieve emergency locking and protect safety.

[0007] Furthermore, a limiting opening is provided on the lower surface of the transverse cylinder, and a limiting plate is slidably connected inside the limiting opening; a side plate is fixedly provided on the side wall of the cylinder, and the upper end of the side plate corresponds to the limiting opening, and a guide groove is provided on the side plate surface, and the inner sliding connection of the guide groove is connected to a slide seat, and the upper end of the slide seat is fixedly connected to the lower end of the limiting plate, and the slide seat is connected to a driving assembly.

When in use, the operator pulls the slide downward, the front spring and the rear spring are compressed, and the limit plate moves downward synchronously and is pulled out of the horizontal cylinder. At this time, under the elastic force of the first spring, the horizontal bolt rushes out of the horizontal cylinder for emergency locking.

[0008] Furthermore, a hand push portion is fixedly provided on the outer side wall of the slide seat, and an anti-slip portion is provided on the outside of the hand push portion, and the anti-slip portion is composed of a plurality of semicircular strips.

Through the setting of the second fixing component, if the first L-shaped connecting rod and the second L-shaped connecting rod cannot be completely locked during the falling process, the operator can manually operate the second fixing component for a second locking, providing further emergency safety protection. Through the setting of the matching components, when the first L-shaped connecting rod and the second L-shaped connecting rod lock the safety rope inside the cylinder, the first tooth groove and the second tooth groove and the convex strip squeeze the safety rope from both sides to firmly fix the safety rope inside the cylinder, thereby enhancing the locking performance. When in use, in the default state, the first spring is compressed, the cross bolt shrinks inside the cross cylinder, and the external rod is used to pull the cross bolt to shrink it inside the cross cylinder.
