Embodiment 1

[0049] refer to Figure 1 to Figure 7 , the main cable 114 fast erection installation method provided in this embodiment includes the following steps:

[0050] S1: Install the first fixing device and the second fixing device on both sides of the canyon, wherein the first fixing device includes the first winch 104, the first cable saddle 106, the first anchor cable 105 and the first ground anchor 103, the first winch 104 and the first ground anchor 103 are set to four respectively, and the four first ground anchors 103 are respectively connected with the four first winches 104 for fixing the first winches 104; the second fixing device includes the second winches 108, the second The cable saddle 110, the second anchor cable 109 and the second ground anchor 107, the second ground anchor 107 is connected with the second hoist 108 for fixing the second hoist 108, and the quick erection and installation method of the main cable 114 provided in this embodiment also There are two set...

Embodiment 2

[0061] refer to Figure 4 , this embodiment also provides a quick erection and installation method for the main cable 114. This embodiment is a further improvement on the basis of the technical solution in Embodiment 1. The technical solution described in Embodiment 1 is also applicable to this embodiment. The disclosed technical solution of Example 1 will not be described again.

[0062] Specifically, the difference between this embodiment and Embodiment 1 is that the fast erection and installation method of the main cable 114 provided by this embodiment is also installed on the chain hoist 101 for placing the main cable 114 on the bank where the first fixing device is installed and The steel frame 102 is more convenient when stacking and installing the main cable 114 like this.

Abstract

The invention provides a quick main cable erecting and mounting method and belongs to the field of construction of canyon cable ways. The method comprises the steps of installing a traction cable, installing a first bearing cable through the traction cable and installing a second bearing cable through the first bearing cable; and finally installing a main cable thorough the second bearing cable, wherein transportation equipment is only required for installation of the traction cable in the installation process. Through the quick main cable erecting and mounting method provided by the invention, the pre-construction cycle is short, the material recovery and utilization rate is high, and the construction cost is low; transportation is conducted mechanically, the required number of personnelis less, and the safety risk of the personnel in the erecting and installing process is low; the process controllable degree of a transportation system is high, and the transportation system can conduct large-span and wide-bridge-deck transportation; the mechanized utilization degree is high, the transportation speed is increased, and the erecting and installing efficiency is high. Mechanical control is adopted in the erecting and installing process, the automation degree is high, and the labor intensity of workers is greatly relieved.

Description

technical field [0001] The invention relates to the field of canyon cableway construction, in particular to a method for quickly erecting and installing a main cable. Background technique [0002] At present, the traditional transportation method of steel wire rope main cables is mainly transported by catwalk, which is mainly composed of load-bearing cables (including cable end length adjustment and connection devices), bridge deck surface, wind resistance system, lighting and warning equipment, etc. The bridge deck The load-bearing cable is composed of 6 twisted φ28 steel wire ropes. The construction period in the early stage is long and the cost is high. The main rope of the steel wire rope is mainly transported manually. The availability of machinery is low, the transportation efficiency is low, and the labor intensity of workers is high. Contents of the invention [0003] The purpose of the present invention is to provide a fast erection and installation method of the...
