The working principle of the technical scheme is as follows: the balance seat device 3 is welded on a propeller strut top beam of the floating crane, after the balance rod 2.1 is inserted into the balance seat 3.1, the positioning plates 3.2 are welded at two ends of the balance seat, the balance rod 2.1 can only horizontally move along the balance seat 3.1 through the stroke slide way, and the cushion backing plate 3.3 and the cover plate 3.4 are fixed at two ends of the balance seat 3.1 through the gasket 3.5 and the screw I3.6. One end of the left steel wire rope 1.1 is connected with the left shaft hole of the balancing pole 2.1 through a pin shaft 1.2 through a self rope joint, and the other end of the left steel wire rope sequentially bypasses a pulley block 1.4 at the top of the propeller strut and a pulley block 1.4 at the head of the arm frame and is wound on the left amplitude-variable winch. Meanwhile, one end of the right steel wire rope 1.3 is connected with the right shaft hole of the balancing pole 2.1 through a pin shaft 1.2 through a self rope joint, and the other end of the right steel wire rope sequentially bypasses a pulley block 1.4 at the top of the propeller strut and a pulley block 1.4 at the head of the arm support and is wound on the right amplitude-variable winch. When the luffing mechanism of the floating crane works normally, the steel wire rope system 1 and the balance rod device 2 share the load generated by the boom system.
When any one steel wire rope in the steel wire rope system 1 is suddenly broken, the load of the whole arm support system acts on the other steel wire rope, the steel wire rope pulls the balance rod 2.1 to move together, the clamping seat of the balance rod 2.1 is clamped on the buffer base plate 3.3 of the balance seat device 3, and the buffer base plate 3.3 can relieve the impact of the balance rod 2.1 on the human body frame. The cover plate 3.4 covers the buffer backing plate 3.2, so that the buffer backing plate 3.2 is uniformly stressed to avoid failure due to overlarge local stress. The wire rope together with the balancing bar 2.1 and the balancing seat device 3 support the boom system and prevent it from falling.
The rotating shaft of the encoder 4.3 is inserted into the locking disc of the rope pulling device 4.2 to be locked so that the rotating shaft and the locking disc are integrated and fixed on the top beam of the propeller strut of the floating crane, the pull ring of the rope pulling device 4.2 is installed on the pull rod 2.2, the pull rod 2.2 is fixed on the balance rod 2.1, the pull ring of the rope pulling device 4.2 moves along with the balance rod 2.1, the displacement of the balance rod 2.1 measured by the rope pulling device 4.2 is recorded and transmitted to the central control system by the encoder 4.3, and the central control system adjusts the position of the balance rod 2.1 at any time through the rotation of the variable-amplitude winch according to the size of the displacement of the balance rod 2.1 so that the balance rod is always kept at the center of the propeller strut. Limit switch 4.1 is installed on the propeller strut back timber, and when encoder 4.3 or rope pulling device 4.2 damaged, along with the displacement grow of balancing pole 2.1, limit switch 4.1 can be touched to rope pulling pole 2.2, and the central control system warning luffing mechanism is shut down, and the manual work is maintained this moment.
The specific actions are as follows:
when the arm support of the floating crane makes amplitude variation motion, the left amplitude variation winch pulls the left steel wire rope 1.1, and the right amplitude variation winch pulls the right steel wire rope 1.3, so that the arm support is pulled up by the left amplitude variation winch and the right amplitude variation winch. Along with the phenomenon that the left and right variable-amplitude winches run asynchronously, the rope outlet speeds of the left steel wire rope 1.1 and the right steel wire rope 1.3 deviate, so that the balance rod 2.1 is pulled to horizontally move along the slide way in the balance seat 3.1 to deviate from the central position. The offset of the balancing rod 2.1 is gradually increased along with the time, the pull rope rod 2.2 is driven to offset together, the size of the offset is recorded by the rope pulling device 4.2 and the encoder 4.3, and when the offset reaches a certain degree, the encoder 4.3 sends a signal to the central system. The central control system adjusts the rotating speed of the two sets of variable-amplitude winches and adjusts the balance rod 2.1 to the center of the herringbone frame.
When encoder 4.3 or rope drawing ware 4.2 damaged, the unable displacement volume size of recording balancing pole 2.1 of encoder 4.3, consequently can't guarantee that the balancing pole is in propeller strut central point and puts, along with balancing pole 2.1's displacement volume grow, when the displacement volume reaches stroke extreme position, limit switch 4.1 can be touched to rope drawing pole 2.2, and the central control system warning luffing mechanism is shut down this moment, carries out manual maintenance.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
