The specific embodiment
Specify the specific embodiment of the present invention below in conjunction with accompanying drawing.
Like Fig. 1, Fig. 2 and shown in Figure 4, the rig mast slewing equipment of the utility model comprises a pair of revolution bracing frame 7, and its top is connected with mast 1 through last fulcrum post axle 2 rotationally, and its underpart is connected with chassis 11 through turning down bearing pin 4 rotationally.
The rig mast slewing equipment of the utility model also comprises the fixation kit that is connected on a pair of revolution bracing frame 7 and chassis 11, and as shown in Figure 6, it comprises latch 3, is with the otic placode 13 and the notched side plate 12 of pin-and-hole.Be set with aiding support seat 6 on the chassis 11, the otic placode 13 of band pin-and-hole just is fixedly installed on this aiding support seat 6 through the mode such as welding.Side plate 12 is fixedly installed on two revolution bracing frames 7.
When carrying out wide-angle, rig creeps into; Need make mast 1 when last fulcrum post axle 2 turns round; Side plate 12 is closely adhered on the aiding support seat 6, and otic placode 13 passes the breach of side plate 12, the pin-and-hole that last latch 3 inserts on the otic placode 13; Thus two revolution bracing frames 7 are fixed together with aiding support seat 6, also are about to two revolution bracing frames 7 and are fixed together with chassis 11.At this moment, mast 1 is under oil cylinder 8 effects, and more than revolution bearing pin 2 is two relatively revolution bracing frames 7 of gyroaxis and chassis 11 revolutions, and is as shown in Figure 3.Said oil cylinder 8 is installed between mast 1 and the chassis 11, and the flexible mast 1 that promotes of its piston rod turns round.
The rig mast slewing equipment of the utility model also comprises the fixation kit that is connected of a pair of revolution bracing frame 7 and mast 1, and is as shown in Figure 7, the otic placode 14 that it comprises latch 5 down, be with pin-and-hole be connected hole slot 15.Otic placode 14 is fixedly installed on the mast 1 through the mode such as welding.Connecting hole slot 15 is arranged on two revolution bracing frames 7.
Creep into when rig carries out low-angle, need make mast 1 when 4 revolutions of turning down bearing pin, otic placode 14 is passed connect hole slot 15, following latch 5 inserts in the pin-and-hole of otic placode 14, thus mast 1 and two revolution bracing frames 7 is fixedly become one.At this moment, mast 1 drives two revolution bracing frames 7 under oil cylinder 8 effects, and below revolution bearing pin 4 is gyroaxis relative chassis 11 revolutions, and is as shown in Figure 4.
When mast 1 be turned back to need creep into angle after, lock so that bore operation this angle.Angle locking makes oil cylinder 8 lockings, does not work through the hydraulic oil of control oil cylinder 8, can realize.In addition,, the locking mechanism of mast 1 can be installed, further, carry out bore operation reliably with mast 1 angle locking from firm consideration.Said mast locking mechanism can be as shown in Figure 1, and the secondary bar 9 that adopts internal and external casing with holes to constitute constitutes with Fixed latches 10.Secondary bar 9 is installed between mast 1 and the chassis 11, and Fixed latches 10 is fixed internal and external casing through the hole on the secondary bar 9.
When needs are set level mast 1 when transporting, then adopt and go up the gyroaxis of fulcrum post axle 2 as mast 1, turn to parallel to the groundly, transport after firm support is fixing.
When last latch 3 was all installed with following latch 5, mast 1, two revolution bracing frame 7 and chassis 11 all fit together and become one, and mast 1 can not turn round.
In addition, it will be understood by those skilled in the art that except that described upward latch 3 and following latch 5, can also adopt other fixed structure to realize two revolution bracing frames 7 and the aiding support seat 6 on chassis 11 or fixing of mast 1, for example bolt structure.
Below only be concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the rights protection scope of the present invention.
