Problems solved by technology

During construction, it is usually necessary to stop the spanning object or build a large spanning frame, but neither of these two options is ideal: first, if the spanning object is stopped, the construction will be very convenient and quick, but for railways, high-speed and important It is almost impossible to shut down live lines; secondly, erecting a large spanning frame does not require shutting down, but it is very time-consuming and laborious, which will greatly affect the construction period. When the renovation task is tight, it will cause great difficulty to the construction

Abstract

The invention discloses a controllable lifting live across equipment, comprising a walking lifting mechanism, a supporting rolling mechanism is arranged on the walking lifting mechanism, the walking lifting mechanism is a crane, and a pulley frame and a pulley are arranged at the end of the lifting arm of the crane , a movable opening is set on the pulley frame, and two special pulleys for isolation nets are respectively set on both sides of the pulley frame. A stay wire connected to the ground anchor is arranged on the lifting arm of the crane. This controllable lifting and crossing equipment is suitable for various voltage levels and various crossing objects such as roads, expressways, railways, etc. It is convenient and fast, saves a lot of manpower and material resources, saves engineering construction costs, and reduces damage to cultivated land and occupation of public land during construction. It is a construction method worth promoting.

Description

technical field [0001] The invention belongs to the technical field of line crossing equipment, and in particular relates to a controllable lifting live crossing equipment and a construction method thereof. Background technique [0002] With the continuous growth of the national economy, the demand for power supply is also increasing. It is necessary to continuously increase the power transmission and transformation capacity, and more transmission lines are needed to ensure the power supply. At the same time, the rapid economic development has also led to the aggravation of the resource imbalance between regions, and the regional allocation of resources requires a lot of transportation and costs, and it is very difficult to convert resources into electrical energy, and then deploy and transmit them through transmission lines. To solve this problem well, my country's 1000kV UHV transmission line is a very good and great pioneering work. Therefore, there are more and more dema...
