Embodiment 1

[0032] Embodiment 1: The high-voltage cable of this embodiment is a super-heavy cable and is used in super high-rise buildings. In order to increase the safety of hoisting, in combination with the analysis of the characteristics of the cable force, the high-voltage cable should be a built-in armored cable, which can withstand The minimum pulling force should be greater than that of YJV with the same diameter 32 type cables, the weight of a single high-voltage cable in this embodiment should not exceed 8 tons, and the hoisting height should not exceed 300 meters, which can also meet the design requirements of general super high-rise buildings. Combine below Figure 1 to Figure 3 Illustrate a kind of steel cable accompanying cable vertical hoisting system of the present invention, it is arranged between two floor slabs on the top floor of the building, namely between the bottom floor 2 and the top floor 1, it comprises: close to the cable well 7 and installed in At least one fi...

Embodiment 2

[0038] Embodiment two: combine below Figure 1 to Figure 3 Illustrate the construction method of hoisting high-voltage cables using a cable vertical hoisting system accompanied by steel cables of the present invention, the specific steps are as follows:

[0039] S1: Install the cable vertical hoisting system between the two floors on the top floor of the building, the first pulley 10 and the weight sensing device 15 are installed on the top floor 1, the second pulley 11, the gravity limiter 16 and the hoist 12 are installed on the bottom floor 2. The steel wire rope 14 of the winch 12 goes around the second pulley 11 and the first pulley 10 in turn, and is arranged in parallel with the high-voltage cable 5 and connected by a plurality of cable fixing fixtures 17;

[0040] S2: Start the winch 12 and tighten the wire rope 14. The high-voltage cable 5 is lifted upward along with the wire rope 14. The weight sensing device 15 converts the tension signal of the wire rope 14 attache...

Abstract

A wirerope-accompanying cable vertical hoisting system and a construction method thereof relate to the technical field of hoisting equipment. Due to lack of monitoring or intelligent spacing measuresin a traditional hoisting mode of high voltage cables in existing super high-rise buildings, critical engineering accidents are caused and high voltage cable laying is difficult. In allusion to the above problems, the wirerope-accompanying cable vertical hoisting system of the invention comprises a first pulley, a second pulley, a hoist, a weight sensing device, a gravity stopper and a controller,wherein the first pulley is close to a cable well and installed at the bottom of a top floor; the second pulley is installed at the bottom flour and is arranged in a staggered manner with the first pulley; the hoist is fixed at the bottom floor and is arranged at interval with the second pulley, and a wire rope of the hoist successively winds second and first pulleys and is arranged in parallel with and fixedly connected with the high voltage cable; the weight sensing device is installed at the top of the first pulley and is used for converting a tension signal of a wire rope carrying the high voltage cable during the hoisting process into an electrical signal; the gravity stopper is disposed at the bottom floor and is used for cutting off power of the hoist; and the controller is respectively in signal connection with the hoist, the weight sensing device and the gravity stopper.

Description

technical field [0001] The invention relates to the technical field of hoisting equipment, in particular to a cable vertical hoisting system accompanied by steel cables and a construction method thereof. Background technique [0002] High-voltage cables are the power transmission medium in super high-rise buildings. They are generally laid in cable wells. If they are not properly laid, they will easily affect various electrical equipment in super high-rise buildings. [0003] Due to the heavy weight of the high-voltage cable and the long vertical laying distance, there are many inconveniences in its hoisting operation. The traditional hoisting method of the high-voltage cable is human-pulled or dragged by a hoist. , and due to the lack of monitoring or intelligent limit measures in the process of pulling high-voltage cables, once the vertically laid high-voltage cables break, the heavy and heavy high-voltage cables that fall rapidly will easily hit the construction workers i...
