Abstract
The invention discloses a flexible attachment device of a tower crane with active control. The flexible attachment device comprises an attachment frame, support rods, actuators, a position sensor and a central computer, wherein the attachment frame is fixed on an attachment wall through the support rods; the actuators are arranged on the support rods; the position sensor is arranged on the attachment frame; the central computer is arranged on a tower body. The flexible attachment device is simple in structure, effective support can be provided for the tower crane, torsional vibration, flexural vibration and swing of the tower body can be eliminated, and overlarge stress is prevented when the stability is improved.
Description
Technical field:
The present invention relates to tower crane technical field, specifically a kind of tower Jack flexible adhesion device of ACTIVE CONTROL.
Background technology:
Tower crane bears a lot of load in the course of the work, along with increasing and the lifting of height of tower joint, need be attached to and on building, guarantee stability.Prior art is mainly rigid support, during reply sudden applied load, can produce larger stress, harm tower machine safety.And existing attachment device lacks ACTIVE CONTROL, be difficult to the vibration of tower machine all directions to be made positive corresponding.
Summary of the invention:
The object of the invention is to solve stability and the safety issue of tower crane in existing technology, a kind of tower Jack flexible adhesion device of ACTIVE CONTROL is provided.
The technical solution used in the present invention is: a kind of tower Jack flexible adhesion device of ACTIVE CONTROL, comprise and adhere to frame, strut bar, actuator, position transduser and central computer, the described frame that adheres to is fixed on and is adhered on wall by strut bar, actuator is installed on strut bar, position transduser is arranged on and adheres on frame, and central computer is arranged on tower body.
Described strut bar comprises the first strut bar, the second strut bar, the 3rd strut bar and the 4th strut bar, on the first strut bar and the 3rd strut bar, actuator is installed, and the second strut bar and the 4th strut bar are rigid support,
The described frame that adheres to has several layers, and each layer adheres to position transduser is installed on frame.Position transduser sends position signal to central computer in real time, central computer calculates the torsion of tower machine and the change in location that angle of bend, cireular frequency, angular acceleration and distance are adhered to wall accordingly, and then send instruction to actuator, provide corresponding ACTIVE CONTROL counter-force, damped vibration rapidly.
It is identical that described each position transduser adheres on frame installation site at each layer, on same vertical curve.
The outstanding advantage of the present invention is:
1, simple in structure, only need several position transdusers, just can measure the change in location that the torsion of tower machine and angle of bend, cireular frequency, angular acceleration and distance are adhered to wall, by differentiating of central computer, replaced the function of speed sensor and acceleration pick-up.
2, the combination of rigid rod and rods can provide effective support for tower crane, can eliminate again tower body torsional oscillation and bending vibrattion and swing, and prevents the generation of excessive stresses when improving stability.
Accompanying drawing explanation:
Fig. 1 is the structural representation of the tower Jack flexible adhesion device of ACTIVE CONTROL of the present invention.
Fig. 2 is the integral installation schematic diagram of the tower Jack flexible adhesion device of ACTIVE CONTROL of the present invention.
Parts title and sequence number in figure: adhere to frame 1, the first strut bar 2, the first actuator 3, the second strut bars 4, position transduser 5, the second actuator 6, the three strut bar 7, the four strut bars 8, adhere to wall 9, attachment device 10, tower body 11, central computer 12.
The specific embodiment:
Below in conjunction with drawings and Examples, technical scheme of the present invention is described further.
As depicted in figs. 1 and 2, the tower Jack flexible adhesion device of ACTIVE CONTROL of the present invention, comprises and adheres to frame 1, the first strut bar 2, the first actuator 3, the second strut bars 4, position transduser 5, the second actuator 6, the 3rd strut bar 7, the four strut bars 8, adhere to wall 9, attachment device 10, tower body 11 and central computer 12.Concrete structure and connection mode are: described in adhere to frame 1 and be fixed on and adhere on wall 9 by the first strut bar 2, the second strut bar 4, the 3rd strut bar 7 and the 4th strut bar 8, the second strut bar 4, the 4th strut bar 8 are rigid rod, for tower machine provides necessary rigid support, the first strut bar 2, the 3rd strut bar 7 are provided with the first actuator 3 and the second actuator 6, for stability and the safety of tower machine provides resilient mounting and ACTIVE CONTROL counter-force.Central computer 12 is arranged on tower body 11, receives the position signal of each position transduser 5.Position transduser 5 is arranged on and adheres on frame 1, and installation site is identical, on same vertical curve, transmits position signal in real time to central computer 12.
When there is torsional oscillation in tower body 11, each position transduser 5 becomes no longer on same vertical curve, central computer 12 passes through to analyze the horizontal throw between each position transduser 5, and by differentiating, calculates windup-degree, cireular frequency and the angular acceleration of tower body 11 each sections.
When tower body 11 bends, central computer 12 is by analyzing the horizontal throw of each position transduser 5 bending directions, and the initial position when there is no displacement makes comparisons, by differentiating, calculate angle of bend, cireular frequency and the angular acceleration of tower body 11 each sections.
When tower body 11 occurs to swing, central computer 12, by analyzing the position of each position transduser 5 and the variation of initial position, calculates and the change of distance of adhering to wall 9, by differentiating, calculates swing size, speed and the acceleration/accel of tower body 11 each sections.
The comprehensive above torsional oscillation of central computer 12, bending and the data that swing, calculate the required best ACTIVE CONTROL counter-force of actuator in each layer of attachment device 10, and then send instruction, by the first actuator 3 and the second actuator 6 execution.
The present invention is simple in structure, can eliminate and comprise tower body torsional oscillation, bending vibrattion and swing, and do not cause excessive counter-force when effective rigid support is provided, and the reinforcing that can be widely used in tower crane is supported.
