Climbing construction ladder for overhauling high-voltage power transmission tower

Abstract

The invention discloses a climbing construction ladder for overhauling a high-voltage power transmission tower, and relates to the technical field of construction ladders. The climbing construction ladder comprises a base plate, a first ladder body, a second ladder body, a third ladder body and a first bevel gear, a supporting plate is arranged at the upper end of the base plate, a mounting gap exists between the supporting plate and the base plate, a motor is fixedly mounted in the mounting gap, the motor is fixedly installed on one side of the upper end face of the base plate, the output end of the motor is connected with a main lead screw, the front end of the main lead screw is matched with a reinforcing mechanism, and a driving bevel gear is fixedly installed at the rear end of the main lead screw. The climbing construction ladder has the beneficial effects that a driving structure drives a third lead screw to rotate, so that a third sliding block on the third lead screw moves upwards relative to a second sliding block, so that a guardrail connected with the third sliding block can be quickly lifted to the highest position through relative synchronous upward movement of the three ladder bodies, time is saved, and the use limitation is reduced.

Description

technical field [0001] The invention relates to the technical field of construction ladders, in particular to a climbing construction ladder used for maintenance of high-voltage transmission towers. Background technique [0002] The transmission tower is the supporting point of the overhead line. If one circuit is erected on the transmission tower, it is a single-circuit transmission tower, and if two circuits are erected on the transmission tower, it is a double-circuit transmission tower. A single circuit means that one load has one power supply. Loop; double loop refers to a load with two power supply loops. Generally, enterprises that require high power supply reliability, or important substations in the region, use double-circuit power supply, which can protect one power supply from power failure for some reason, and the other power supply can continue to supply power. However, for general power supply reliability requirements are not High small and medium-sized users ...

AI Technical Summary

Problems solved by technology

Generally, enterprises that require high power supply reliability, or important substations in the region, use double-circuit power supply, which can protect one power supply from power failure for some reason, and the other power supply can continue to supply power. However, for general power supply reliability requirements are not High small and medium-sized users often use a single power supply for power supply. Due to the danger of the transmission tower, the transmission tower needs to be repaired and maintained intermittently.

[0003] When overhauling the transmission tower, maintenance personnel need to manually place the climbing construction ladder, and the adjustment of the height of the construction ladder requires manual operation, which is extremely time-consuming, has relatively large limitations in use, and reduces certain work efficiency. When the personnel are working, someone needs to support the construction ladder below, which wastes a certain amount of human resources and has low practicability. Therefore, we propose a climbing construction ladder for overhauling high-voltage transmission towers
