Problems solved by technology
At present, the synchronization of each hoist is realized by direct communication between the commander and the operator of each hoist through wireless intercom equipment. Due to the large interference of on-site communication and the influence of human factors, the synchronization accuracy is affected.

Embodiment Construction
[0014] Such as figure 1 As shown, the modular distributed winch integrated control system is characterized in that: the multi-winch integrated control computer 10 is networked with multiple single winch monitoring and execution modules 9 through the public communication network 11, and each single winch monitoring and execution module 9 includes a single Hoist operation console 8, on-site data acquisition transmitter 7, rope storage drum torque motor controller 6, frequency conversion control cabinet 5, load sensor 4, screw encoder 3, torque motor 2, high-power frequency conversion motor 1. The screw encoder 3 is fixed on the rope reel shaft of the hoist driven by the high-power frequency conversion motor 1, and the load sensor 4 is installed on the wire rope guide fixed pulley to obtain the running speed and wire rope tension of multiple hoists; the load sensor 4, the screw encoder 3 are respectively electrically connected to the interface of the on-site data acquisition tran...

The invention relates to a modularized distribution type winch integration control system, which comprises a multi-winch integration control computer, a single-winch operation console and an integral single-winch control and data collection executing mechanism, wherein the multi-winch integration control computer is connected with the single-winch operation console through a wired and wireless industrial Ethernet, the work of a high-power variable-frequency motor is controlled by a variable-frequency control cabinet in the single-winch control and data collection executing mechanism, and a torque motor is controlled by a rope storage cylinder torque motor controller to complete the synchronous winding and unwinding of a steel wire rope. For the running state of equipment at site, a spiral encoder and a load sensor can collect the winding and unwinding speed signals and absolute displacement signals of the steel wire rope, the collected data is sent into the single-winch operation console by a site data collection transmitter, and then is sent to the multi-winch integration control computer by the operation console through the industrial Ethernet, and finally the integration control computer is used for synchronously controlling multiple winches in real time according to the process requirements.
Description
technical field [0001] The invention relates to a winch traction control system used for main cable erection and bridge deck erection in the construction of a suspension bridge. Especially the modular distributed winch integrated control system. Background technique [0002] With the rapid development of my country's road traffic and other infrastructure, as the suspension bridge with the largest spanning capacity, it has gradually become one of the preferred bridge types for crossing rivers, seas and canyons. The main cable of the suspension bridge is its main force-bearing part. Modern suspension bridges generally use parallel steel wire main cables, which are composed of prefabricated high-strength galvanized parallel steel wire bundles (PWS commonly known as "cable strands"). The traction system is completed by the construction technology of aerial traction; for the suspension bridge located in the mountain canyon, the bridge deck erection construction also needs to use...
