Description of reference numerals: 1-cylinder, 2-gyro-rotor, 3-variable-amplitude steel wire rope, 4-crane arm, 5-pull bar, 6-hoist rope, 7-pulley, 8-promote hopper, 9-75 ° limit switch, 10-30 ° limit switch and 11-Shears.
Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Figure 1: spacing in order to what can effectively realize crane arm 4, that guarantees when crane arm 4 works is safe and reliable, the present invention includes cylinder 1 and be positioned at the gyro-rotor 2 on described cylinder 1, described gyro-rotor 2 is provided with crane arm 4 and the luffing mechanism for controlling described crane arm 4 amplitude; Gyro-rotor 2 is provided with the amplitude detection mechanism for detecting crane arm 4 amplitude, and described amplitude detection mechanism is connected with crane controller, according to amplitude detection mechanism, crane controller determines that the amplitude of crane arm 4 controls the mode of operation of luffing mechanism.
Particularly, cylinder 1 is fixedly installed in desired position, and gyro-rotor 2 is arranged on the top of cylinder 1, and gyro-rotor 2 can rotate on cylinder 1.One end of crane arm 4 is hinged on gyro-rotor 2, and during work, crane arm 4 can swing around the position be connected with gyro-rotor 2, and the amplitude that crane arm 4 swings is driven by luffing mechanism.Crane controller is for controlling the work of hoisting crane, and being implemented as known by the art personnel of crane controller, repeats no more herein.The amplitude of crane arm 4 is determined by amplitude detection mechanism; amplitude detection mechanism will determine that the amplitude transfer of crane arm 4 is in crane controller; crane controller adjusts the mode of operation of luffing mechanism according to the amplitude receiving crane arm 4; when namely making luffing mechanism driving crane arm 4 luffing; the amplitude of crane arm 4 can be made to be in the safe work state of regulation all the time, to realize the available protecting to crane arm 4.
Described amplitude detection mechanism comprises 30 ° of limit switches 10 and 75 ° of limit switches 9, and described 30 ° of limit switches 10,75 ° of limit switches 9 are all connected with crane controller.
In the embodiment of the present invention, when crane arm 4 is 30 ° with the angle of horizontal direction, the location status that crane arm 4 can be in 30 ° by 30 ° of limit switches 10 transfers in crane controller.When crane arm 4 is 75 ° with the angle of horizontal direction, the location status that crane arm 4 can be in 75 ° by 75 ° of limit switches 9 transfers in crane controller.The process that crane controller controls luffing mechanism driving crane arm 4 is: when crane arm 4 is in the location status of 30 °, crane controller controls luffing mechanism can only drive crane arm 4 amplification, can not amount of decrease, when crane arm 4 is in the location status of 75 °, crane controller controls luffing mechanism can only amount of decrease, can not amplification, thus maloperation can be avoided to damage loop wheel machine, eliminate potential safety hazard.
Described luffing mechanism comprises pull bar 5, and one end of described pull bar 5 is connected with crane arm 4 by variable-amplitude steel wire rope 3, and the other end of pull bar 5 is connected with Shears 11, and described Shears 11 is installed on gyro-rotor 2.
