Fig. 2 is the structural representation of the arm head of upright arm shelf structure of the present invention;
Fig. 3 is the schematic process flow diagram that plays arm method of upright arm shelf structure of the present invention;
Fig. 4 a is that rising in arm method of upright arm shelf structure of the present invention played arm view one;
Fig. 4 b is an arm view two of the arm method that rises of upright arm shelf structure of the present invention.
The specific embodiment
Below in conjunction with schematic diagram and concrete operations embodiment, the invention will be further described.
The present invention first discloses a kind of upright arm shelf structure, and as shown in Figure 1, this upright arm shelf structure comprises intermediate arm 1, the upper end of intermediate arm 1 is connected with arm head 2, lower end is connected with root joint arm 3, and wherein, root joint arm 3 lower ends are connected with main platform 0 by two hinge (not shown)s.The design distinguished of two hinges is in four hinges of the prior art or hinge (two hinges are fixed+two hinges use oil cylinders) design between two, and two hinges can guarantee that jib realizes automatically cocked before vertical working.
As shown in Figure 2, arm head 2 is dismantled and assembled structure, convenient for assembly, and arm head 2 is provided with road wheel 21, and the side of arm head 2 comprises central region 22 and is symmetrically distributed in the alar part region 23 of central region 22 both sides.
Further, road wheel 21 is located at and is arranged in central region 22 both sides towards the top in the alar part region 23 of fuselage front side.
Further, central region 22 is rectangle, and alar part region 23 is right-angled triangle, the side of a right-angle side next-door neighbour central region 22 of this right-angled triangle, and another right-angle side of right-angled triangle and the top margin of central region 22 are located along the same line.
Being arranged in central region both sides realizes dismantled and assembled towards the alar part region 23 of fuselage front side by bearing pin 24 and central region 22.Optimally, bearing pin 24 has 4, and bearing pin 24 is the component that easily obtain on the market, facilitates realization of the present invention.
The present invention discloses a kind of arm method that rises of upright arm shelf structure again, as shown in Figure 3, best, specifically comprises the following steps:
The first step, for another example shown in Fig. 4 a, is shelved on horizontal plane except the jib towards the alar part region 23 of fuselage front side on arm head 2 unloading, and by the wire rope 01 through arm head 2 one end skids wheels 25, carries out luffing;
Second step, when jib is raised to certain angle, at arm head 2 mounting portion bearing pins, further, is on arm head 2, first to install two towards the bearing pin of fuselage 00 front side.
The 3rd step when jib continues to be lifted to another certain angle, is installed remaining part bearing pin on arm head 2, further, is that remaining 2 bearing pins are installed on arm head 2;
The 4th step, as shown in Figure 4 b, when jib continues to be lifted to another certain angle, will close towards the alar part region of fuselage 00 front side and arm head 2 pins on arm head 2 by bearing pin, and last until jib is in complete erectility.
The arm process that falls is the process contrary with playing arm, when whole jib lands, because 2 times parts of arm head are provided with road wheel 21, not only can support, also can so that jib walk on the ground.
The present invention finally discloses a kind of dynamic compaction machinery, and this dynamic compaction machinery has upright arm shelf structure described above.Owing to there is difference in upright arm shelf structure and the prior art of dynamic compaction machinery of the present invention, other part-structures are not drawn, but those skilled in the art can grasp the structure of other parts of the dynamic compaction machinery that adopts above-mentioned upright arm shelf structure in conjunction with prior art, do not repeat them here.
In sum, the present invention adopts upright arm shelf structure, and during construction, recoil strength vertically upward, has improved the stressing conditions of jib greatly, and whole jib stability is improved; Upper joint arm is comparatively easy when dismounting, and root joint arm adopts two hinges simultaneously, therefore, before jib vertical working, can realize from cocked.
Above specific embodiments of the invention be have been described in detail, but the present invention is not restricted to specific embodiment described above, it is just as example.To those skilled in the art, any equivalent modifications that this invention is carried out and alternative also all among category of the present invention.Therefore, equalization conversion and the modification done without departing from the spirit and scope of the invention, all should contain within the scope of the invention.
