Abstract
An automatic balance adjusting system for a hanging scaffold in vertical shaft construction is especially suitable for a winder control system with PLC control and frequency control. The system comprises tension sensors arranged on suspension wire ropes, an attitude angle sensor and a signal acquisition card installed on the hanging scaffold, and PLC controllers arranged in winder chambers. The PLC controllers acquire hanging scaffold attitude angle and wire rope tension signals in real time through the attitude angle sensors and the tension sensors, calculates the length differences between the lengths of the four wire ropes and the average length of the four wire ropes and the tension differences between the tensions of the four wire ropes and the average tension of the four wire ropes, calculates the rotating speed adjusting amounts of four winders based on the principle that the lengths of the four wire ropes simultaneously draw close to the average length and the tensions of the wire ropes simultaneously draw close to the average tension, and drives the winders to carrying out the adjusting. With the automatic balance adjusting system for the hanging scaffold in vertical shaft construction, in the operation process of a hanging scaffold winder mechanism, the hanging scaffold can be automatically adjusted from an inclination pose to a horizontal state, and the wire rope tensions can be automatically adjusted from a non-uniform distribution state to an equalization state.
Description
Technical field
The present invention relates to a kind of Automatic Balance Regulation system of shaft construction hanging scaffold, the shaft construction hanging scaffold that is particularly useful for PLC control and frequency control in the operational process of pit shaft leveling hanging scaffold attitude, balanced four suspension wire rope tensions, guarantee that hanging scaffold is steady, safety, reliability service.
Background technology
Platform hoist mechanism is the visual plant in the shaft construction process, in the shaft building construction operation, needs to promote and transfer hanging scaffold.Because hanging scaffold does not have guide piece in operational process; The hanging scaffold barycenter is eccentric asynchronous with four winch running velocitys; It is not steady that these factors all can cause hanging scaffold in lifting process, to move, run-off the straight easily, and the steel wire rope tension distribution that also can cause suspending hanging scaffold in midair becomes inhomogeneous.The bevelled hanging scaffold will certainly jeopardize the personal safety of operating worker; Uneven Tension Distribution can influence the whole service life of steel rope on the one hand, also can produce potential safety hazard on the other hand.At present; The platform hoist control system is owing to adopted the pioneering technology of PLC control and frequency control; The conventional means of relay control system is undergone technological transformation; Though improved the synchronism of moving between the winch, The whole control system lacks the message feedback to hanging scaffold attitude and steel wire rope tension, and the mode of this open loop causes still existing in the hanging scaffold operational process hanging scaffold to tilt and the steel wire rope tension problem of uneven distribution.After hanging scaffold moves a segment distance run-off the straight; Must hoister system be stopped and carry out leveling; Continue operation by operative employee's coordinated of signalman on the hanging scaffold and ground winch again after with the hanging scaffold manual leveling; This has not only reduced production efficiency, also has the potential safety hazard that produces because of the manual operation error simultaneously.
Summary of the invention
The objective of the invention is to overcome weak point of the prior art, provide a kind of system simple, easy to operate, can be automatically with the Automatic Balance Regulation system of the shaft construction hanging scaffold of hanging scaffold from inclination pose automatically regulating to horizontality.
The Automatic Balance Regulation system of shaft construction hanging scaffold of the present invention; Comprise hanging scaffold, be uniformly distributed with four steel ropes of suspension hanging scaffold, control four winches, the PLC controller of four steel ropes respectively; Said being uniformly distributed with on four steel ropes that are suspended on the hanging scaffold is separately installed with tension pick-up; Attitude angle transducer and data acquisition card are installed on the hanging scaffold; Tension pick-up and attitude angle transducer are through communication cable and be arranged on the acquisition of signal card connection on the hanging scaffold, and data acquisition card is connected with the PLC controller that is arranged on hoist house through communication cable, and the PLC controller is connected with the winch that is arranged on well head through communication cable; The said X that is installed in the attitude angle transducer on the hanging scaffold, the Y principal axis of inertia respectively with rectangle by the point of connection parallelogram of steel rope and hanging scaffold, the Z principal axis of inertia of attitude angle transducer is perpendicular to hanging scaffold and straight up.
Beneficial effect: owing to adopted technique scheme; The utility model can be in the operational process of platform hoist mechanism with hanging scaffold from inclination pose automatically regulating to horizontality; With steel wire rope tension from state automatically regulating pockety to equilibrium state; Be best suited for the Winch control system that has adopted PLC control and frequency control, guarantee hanging scaffold steadily, safety, reliability service, specifically advantage is mainly:
1, regulates the rotating speed of winch through the message feedback of hanging scaffold attitude angle, make hanging scaffold in operational process, keep horizontality, solved hanging scaffold and moved behind the segment distance problem with regard to run-off the straight;
2, regulate the rotating speed of winch through the steel wire rope tension message feedback, make steel wire rope tension distribute on the one hand and become evenly, can avoid adopting separately attitude angle to feed back the problem of the steel rope slack rope that carries out the leveling of hanging scaffold attitude and produce on the other hand;
3, employing Automatic Balance Regulation mode has replaced the mode of field man manual regulation, has improved the leveling efficient of hanging scaffold, has avoided the misoperation of manual shift, has improved the safety and the reliability of winch operation.
