Embodiment 1

[0034] This embodiment provides an active cable release device;

[0035] Such as Figure 1-Figure 4 As shown, the cable active cable release device in this embodiment includes a base 1 and a cable tray bracket located on the base, the cable tray bracket is used to place the cable tray 13, and the base is provided with a driving device. The driving device is used to drive the cable reel to rotate on the cable reel bracket, and the cable reel bracket is also provided with a cable reel brake, and the cable reel brake is used to brake the cable reel.

[0036] In the present invention, a cable tray bracket for placing the cable tray is arranged on the base, and a driving device for driving the cable tray to rotate on the cable tray bracket is arranged on the base, the rotation speed of the cable tray is controlled by the driving device, and It is not affected by the speed of artificially pulling the cable. At the same time, a cable disc brake is installed on the cable disc bracket...

Embodiment 2

[0044] This embodiment provides a method for using an active cable release device;

[0045] Such as Figure 1-Figure 4 As shown, the use method of the cable active cable release device in the present embodiment comprises the following steps:

[0046] a. Use lifting equipment to lift the cable tray to the cable tray bracket, and after passing through the support shaft along the center hole of the cable tray, fix the two ends of the support shaft on the cable tray bracket with bolts, that is, fix them on both sides on a frame;

[0047] b. The end of the cable is lapped and bound with the loop lead wire, that is, it is bundled with the small-diameter traction wire rope used for pulling the cable, so that the cable can be pulled out through the lead wire;

[0048] c. Start the driving device to drive the cable reel 13 to rotate, and at the same time pull the cable 14 outwards with the lead wire, so as to avoid the accumulation of cables near the cable reel.

[0049] The use met...

Abstract

The invention discloses an active cable unwinding device and a use method. The active cable unwinding device comprises a base and a cable disc bracket arranged on the base, and the cable disc bracketis used for placing a cable disc; the base is provided with a driving device which is used for driving the cable disc to rotate on the cable disc bracket, the cable disc bracket is also provided witha cable disc brake, and the cable disc brake is used for braking the cable disc. According to the active cable unwinding device, the cable disc bracket used for placing the cable disc is arranged on the base, the driving device used for driving the cable disc to rotate on the cable disc bracket is arranged on the base, and the rotation speed of the cable disc is controlled by the driving device and not influenced by the manual cable drawing speed; the cable disc brake used for braking the cable disc is arranged on the cable disc bracket, the cable disc can be braked according to requirements,the active cable unwinding device can make the cable unwinding speed uniform and controllable, and the situation that since a part of a cable suddenly drops after passing through a tower, the cable disc is out of control and correspondingly the other part of the cable on the cable disc is entangled can be avoided.

Description

technical field [0001] The invention relates to the field of cable hoisting systems, in particular to an active cable release device and a use method thereof. Background technique [0002] The cable hoisting construction method is a method of hoisting prefabricated components into a bridge through a cable hoisting system. The cable hoisting system can be divided into four basic components according to its working nature: main cable, working cable, tower and anchoring device. Among them, the working cable includes lifting cable, traction cable and buckle cable. The working principle of cable hoisting is to use the main cable to bear the weight and serve as the running track of the sports car. The lifting device and traction device on the main cable sports car will lift, lift, transport and install the components. [0003] The main rope of the cable hoisting system is generally a large-diameter steel wire rope. The length of each steel wire rope is more than 1600m. When layi...
