Description

Overhead power transmission lifting device Technical Field The utility model belongs to the technical field of power transmission engineering, and particularly relates to an overhead power transmission hoisting device. Background The overhead for power transmission is a steel structure facility for supporting and erecting a high-voltage power transmission line, and is generally composed of a steel structure bracket and a concrete foundation pile. The steel structure support is used as a main structure and is responsible for bearing equipment such as wires and insulators, rectangular tower foundation piles constructed by concrete are arranged at four corners of the support, and the foundation piles are deeply buried underground to play roles in stabilizing the whole structure, dispersing loads and preventing sedimentation, so that the overhead is ensured to be stable under the action of severe weather or external force, and the safe operation of a power transmission line is ensured. The design combines strength and durability, and is a common support form in power transmission networks. At present, construction materials for construction of personnel on an elevated frame usually depend on large-scale hoisting vehicles such as a crane for transportation and hoisting, and the mode has a plurality of defects. Firstly, the cost of leasing, fuel oil and maintaining of large-scale hoisting equipment is high, the economic burden of construction is increased, and the cost performance is extremely low especially in small-scale or scattered operation. Secondly, vehicles such as cranes and the like are large in size and heavy in weight, and when a farmland, a forest land and the like are in a loose or narrow place for passing, surface crops can be seriously crushed, soil structures can be damaged, subsequent cultivation is affected, and even peasant disputes are caused. In addition, when hoisting small-volume, multiple batches of material, frequent lifting, moving and positioning can lead to the operating efficiency low, are difficult to satisfy the needs of fine construction. Meanwhile, the dispatching and transportation of large-scale equipment are limited by road conditions, the accessibility of the large-scale equipment in remote or terrain complex areas is poor, and the construction flexibility is further restricted. Finally, the traditional hoisting mode has higher requirements on the skills of operators, and certain safety risks exist, such as the problem that the suspension arm collides with an overhead structure or the load swings under the influence of wind power, and the like, so that the construction hidden trouble is increased. Accordingly, there is a need in the art for a new material transport solution that is more lightweight, efficient and has little impact on the environment. Disclosure of utility model Aiming at the problems of high cost, low operation efficiency, poor site adaptability, easy damage to farmland crops and potential safety hazard caused by the fact that the overhead construction depends on large hoisting equipment in the prior art, the utility model provides an overhead power transmission hoisting device.
