Central control device of well drilling winch in vertical shaft construction

Abstract

The invention discloses a central control device of a vertical shaft construction well-drilling winch, comprising a central control selection button SB5 inside a central control cabinet, a local control selection button SB6 and a plurality of single vertical shaft construction well-drilling winch selection buttons SBn and a plurality of single vertical shaft construction well-drilling winch control devices. The central control device connects the plurality of single vertical shaft construction well-drilling winch control devices into an integer by one single vertical shaft construction well-drilling winch control device, replaces multi-men synchronous operation with one-man operation, not only has good operation synchronicity and safety, but also has manpower saving, thereby being the central control device of the vertical shaft construction well-drilling winch, which is more advanced than a control device of the traditional vertical shaft construction well-drilling winch.

Description

technical field [0001] The invention relates to a control electric appliance, in particular to a centralized control device for sinking drawworks in shaft construction. Background technique [0002] During shaft construction, multiple sinking winches are used to suspend or tension the same equipment at the same time, such as hanging pans and formwork. According to the design, multiple sinking winches are arranged in the stable car group on both sides of the shaft, and the supporting electric control cabinets and operating systems are arranged in the electric control rooms on both sides. [0003] If decentralized control is adopted, there are the following disadvantages: [0004] (1) Multiple people are required to operate on both sides, which wastes manpower and increases wage expenditure; [0005] (2) It is difficult to synchronize the signal transmission and the sensitive response of each operator, and it is prone to operational confusion and even mistakes; [0006] (3)...

AI Technical Summary

Problems solved by technology

[0004] (1) Multiple people are required to operate on both sides, which wastes manpower and increases wage expenditure;

[0005] (2) It is difficult to synchronize the signal transmission and the sensitive response of each operator, and it is prone to operational confusion and even mistakes;

[0006] (3) It is easy to cause the steel wire rope to be stressed alone, and long-term use will reduce the safety factor of the steel wire rope, and even a broken rope accident will occur;

[0007] (4) The adjustment time is long, which directly affects the construction cycle, which in turn affects the progress, duration and benefits of the project

During the construction process, the hanging plates and formwork are frequently lifted and dropped, which directly affects the construction period and project progress
