Double-winch synchronous control system

Abstract

The invention relates to a double-winch control system, particularly to a double-winch synchronous control system. The double-winch synchronous control system comprises a front winch, a back winch, a front balance valve, a back balance valve, a front two-position three-way magnetic valve, a back two-position three-way magnetic valve and a one-way speed regulation valve group, wherein balance valves are mounted on the front winch and the back winch, the one-way speed regulation valve group is connected onto lifting oil ways of the front winch and the back winch, the front two-position three-way magnetic valve is connected between a Br port and a reducer brake port m of a front winch motor, the back two-position three-way magnetic valve is connected between a Br port and a reducer brake port m of a back winch motor, two M2 ports of the front winch and the back winch are connected, and two M1 ports of the front winch and the back winch are connected. According to the double-winch synchronous control system, synchronous speed regulation performance is stable and reliable when two winches place grab buckets down, loads of the two winches can be balanced when the grab buckets are lifted, unbalance loading cannot be caused, pipeline connection is simple, the cost is low, and the system is convenient to operate.

Description

Technical field [0001] The invention relates to a continuous wall double winch control system, in particular to a double winch synchronous control system. Background technique [0002] Larger continuous wall grabs generally use double main winches to control grab lifting or lowering. Lifting grabs generally do not require synchronization accuracy, but lowering grabs require higher synchronization accuracy, because whether or not the lowering is synchronized will directly Affect whether the grab is vertical, and thus the quality of the groove. During the operation of the double main winch, it is easy for the front and rear main winches to be out of sync or uneven load, which will cause the grab bucket to tilt and the quality of the trough will be low. At present, some domestic continuous wall manufacturers have not completely solved this problem. Summary of the invention [0003] In order to overcome the shortcomings of the prior art, the present invention provides a double winch...

Problems solved by technology

[0002] Larger diaphragm wall grabs generally use double main hoists to control the lifting or lowering of the grab. The lifting grab generally does not require synchronization accuracy, but the lowering grab has higher requirements for synchronization accuracy, because whether the lowering is synchronized will directly Affects whether the grab is vertical, thus affecting the quality of grooving

During the operation of double main winches, it is easy for the front and rear main winches to be asynchronous or unbalanced, which will cause the grab bucket to tilt and the quality of the groove to be low

At present, some domestic diaphragm wall manufacturers have not completely solved this problem.
