The specific embodiment
Below in conjunction with schematic diagram and concrete operations embodiment the present invention is described further.
The present invention discloses a kind of upright arm shelf structure earlier, and is as shown in Figure 1, and this upright arm shelf structure comprises intermediate arm 1; The upper end of intermediate arm 1 is connected with arm head 2; The lower end is connected with root joint arm 3, and wherein, root joint arm 3 lower ends are connected with main platform 0 through 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 cylinder) design in twos, and two hinges can guarantee that jib realization before upright work is cocked automatically.
As shown in Figure 2, arm head 2 is dismantled and assembled structure, and is 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 the alar part zone 23 that is symmetrically distributed in central region 22 both sides.
Further, road wheel 21 is located at and is arranged in the top of central region 22 both sides towards the alar part zone 23 of fuselage front side.
Further, central region 22 is a rectangle, and alar part zone 23 is a right-angled triangle, the side of the 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 the central region both sides realizes dismantled and assembled towards the alar part zone 23 of fuselage front side through bearing pin 24 and central region 22.Optimally, bearing pin 24 has 4, and bearing pin 24 is the component that obtain easily on the market, convenient realization of the present invention.
The present invention discloses a kind of arm method that rises of upright arm shelf structure again, and is 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 the horizontal plane unloading except the jib towards the alar part zone 23 of fuselage front side on the arm head 2, carries out luffing through the wire rope 01 that passes arm head 2 one end skids wheel 25;
Second step when jib is raised to certain angle, at arm head 2 mounting portion bearing pins, further, was that two bearing pins towards fuselage 00 front side are installed earlier on arm head 2.
The 3rd step, when jib continues to be lifted to another and decides angle, the remaining part bearing pin is installed on arm head 2, further, be that remaining 2 bearing pins are installed on arm head 2;
In the 4th step, shown in Fig. 4 b, when jib continues to be lifted to another and decides angle, with closing with arm head 2 pins towards the alar part zone of fuselage 00 front side on the arm head 2, be in complete erectility until jib at last through bearing pin.
The arm process that falls is and plays the opposite process of arm, when whole jib lands,, not only can support because arm head 2 lower parts are equipped with road wheel 21, also can so that jib walk on the ground.
The present invention discloses a kind of dynamic compaction machinery at last, and this dynamic compaction machinery has like above-mentioned upright arm shelf structure.Because there are difference in the 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 combine prior art to grasp the structure of other parts of the dynamic compaction machinery that adopts above-mentioned upright arm shelf structure, do not repeat them here.
In sum, the present invention adopts the upright arm shelf structure, and recoil strength has improved the stressing conditions of jib vertically upward greatly during construction, and whole jib stability is improved; Last joint arm is more or less freely when dismounting, and root joint arm adopts two hinges simultaneously, therefore before the upright work of jib, can realize from cocked.
More than specific embodiment of the present invention is described in detail, but the present invention is not restricted to the specific embodiment of above description, it is just as example.To those skilled in the art, any equivalent modifications that this invention is carried out with substitute also all among category of the present invention.Therefore, not breaking away from impartial conversion and the modification of having done under the spirit and scope of the present invention, all should contain within the scope of the invention.
