Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
The adjustable hoisting bracket of the present invention as shown in Figure 1 to Figure 3, by arm 3,9, hanger 1,6,11, rectangular tube 5, digonal link 15,20, multistage hydraulic cylinder 18, pipe 12,14,21,23, bearing pin 7,13,22 and bolt, nut fastener 2,4,8,10,16,17,19 compositions.
Arm 3,9 is rectangular beam, and rectangular tube 5 is rectangular section tube, and arm 3 and arm 9 are in the horizontal direction side by side and through rectangular tube 5, and three between any two can relative sliding, and rectangular tube 5 pairs of arms 3,9 play guiding and constraint.At arm 3,9 and rectangular tube 5 on all arrange a series of through hole, by carrying out between different hole coordinating and inserting bearing pin 7, can to arm 3,9 carry out being connected locking with rectangular tube 5.
Hanger 6 is arranged in the middle part of rectangular tube 5 and weld together, hanger 1, and 11 are arranged in arm 3, the two ends of 9 and with arm 3,9 weld togethers.When lifting by crane, hanger 6 is connected with suspension hook, and hanger 1,11 is connected with by the Heave Here of hanging works.
Digonal link 15,20 is square-section bar, digonal link 15,20 in top and bottom respectively with arm 3,9 and multistage hydraulic cylinder 18 hinged.Wherein, digonal link 15 is hinged by bolt, nut fastener 8 at the right-hand member of top and arm 3, hinged by bolt, nut fastener 19 in the piston rod end of bottom and multistage hydraulic cylinder 18; Digonal link 20 is hinged by bolt, nut fastener 4 at the left end of top and arm 9, hinged by bolt, nut fastener 17 in the cylinder ends of bottom and multistage hydraulic cylinder 18.In addition, digonal link 15 and digonal link 20 are also hinged by bolt, nut fastener 16 between the two.
Pipe 12,14,21,23 is circular tube, pipe 12,23 insert pipe 14 respectively, in 21 and can relative sliding, pipe 12 be hinged by bolt, nut fastener 10 with the right-hand member of arm 9, and pipe 23 is hinged by bolt, nut fastener 2 with the left end of arm 3, pipe 14 is hinged by bolt, nut fastener 17 with the cylinder ends of multistage hydraulic cylinder 18, and pipe 21 is hinged by bolt, nut fastener 19 with the piston rod end of multistage hydraulic cylinder 18.At pipe 12,14,21, arrange a series of through hole on 23, by carrying out between different hole coordinating and inserting bearing pin 13,22, can to pipe 12,14,21,23 carry out connection locking.
Multistage hydraulic cylinder 18 is telescopic hydraulic oil cylinder, and its piston rod can extend and shorten, the piston rod end of multistage hydraulic cylinder 18 and digonal link 15 and pipe 21 hinged, the cylinder ends of multistage hydraulic cylinder 18 and digonal link 20 and pipe 14 hinged.The angle controlled between multistage hydraulic cylinder 18 pairs of digonal links 15 and digonal link 20 regulates, and drives arm 3,9 to move along its length by digonal link 15,20, and can reach hanger 1,11 spacing carry out the object regulated.
Bearing pin 7,13,22 are mainly used in arm 3, the connection between 9 and rectangular tube 5, between pipe 12 and pipe 14, between pipe 21 and pipe 23.
Bolt, nut fastener 2,4,8,10,16,17,19 are mainly used in arm 3,9, digonal link 15,20, pipe 12,14,21,23, hinged between multistage hydraulic cylinder 18.
When lifting by crane, arm 3,9 and rectangular tube 5 mainly bear bending and shearing effect, digonal link 15, and 20 mainly bear axial tension effect, and multistage hydraulic cylinder 18 and pipe 12,14,21,23 mainly bear axle pressure effect.
Before carrying out lifting operation, first regulate hoisting bracket, mainly carry out two adjustments: 1) regulate length of boom and the distance between hanger 1 and hanger 11 according to by the spacing of hanging the Heave Here of works; 2) according to the position being regulated hanger 6 by the center-of-gravity position hanging works.Section 1 regulating step is as follows: first by arm 3, connection bearing pin 7 between 9 and rectangular tube 5, between pipe 12 and pipe 14, between pipe 21 and pipe 23,13,22 take out, and the piston rod then controlling multistage hydraulic cylinder 18 stretches, and regulates the angle between digonal link 15 and digonal link 20, and by digonal link 15,20 drive arm 3,9 to move along its length, till length of boom meets the requirements.In control process, the height of hoisting bracket and cross sectional moment of inertia automatically regulate, when the piston rod of multistage hydraulic cylinder 18 shortens, distance between hanger 1 and hanger 11 increases, the height of hoisting bracket then increases automatically, otherwise, the highly automated reduction of hoisting bracket.Section 2 regulating step is as follows: along arm 3, and 9 slip rectangular tubes 5, till the position of hanger 6 meets the requirements.After above-mentioned two adjustments complete, then by bearing pin 7,13,22 insert in the through hole between arm 3,9 and rectangular tube 5, between pipe 12 and pipe 14, between pipe 21 and pipe 23.In order to proof strength, above-mentioned three place's connecting portions all must not be less than two bearing pins.
Bracket adjustment to be lifted is complete, then by shackle, suspension ring, lifting rope etc., hanger 6 is connected with load hook by equipment, by hanger 1,11 are connected with by the Heave Here of hanging works, then can start lifting operation.
Above-described is only the preferred embodiment of the present invention, the invention is not restricted to above embodiment.Be appreciated that the oher improvements and changes that those skilled in the art directly derive without departing from the basic idea of the present invention or associate, all should think and be included within protection scope of the present invention.
