In order to make those skilled in the art person understand the utility model scheme better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
For ease of understanding and describing succinct, hereafter make an explanation in conjunction with dynamic compaction machinery and changing-breadth system thereof, beneficial effect part no longer repeats to discuss.
Please refer to Fig. 3 to Fig. 5; Fig. 3 shows the connection diagram of the jib of dynamic compaction machinery and the drag-line of changing-breadth system in specific embodiment; Fig. 4 is the structural representation of drag-line in Fig. 3; Fig. 5 is the decomposing schematic representation of drag-line in Fig. 4.
In this embodiment, dynamic compaction machinery comprises platform, is installed on the jib 10 of platform, and is installed on the changing-breadth system between platform and jib 10; During work, jib 10 is drawn high operating angle by changing-breadth system, and makes jib 10 keep motionless, and hammer ram puts down after being hung and rising to suitable height, and then is hung to rise and put down, thus repeatedly beats ground, to loosen the soil to compacting.
Wherein, changing-breadth system comprises the luffing elevator, luffing assembly pulley 20 and the traction cable that are fixedly arranged on platform; Luffing assembly pulley 20 is connected by traction cable with the head of jib 10, and the stay cord of luffing elevator is wound in luffing assembly pulley 20.During work, realize jib 10 by the adjustment of luffing elevator to luffing assembly pulley 20 and to hoist the change of amplitude.
Particularly, the traction cable of changing-breadth system is made up of drag-line part, the reliability be connected with luffing assembly pulley 20 for raising jib 10 and stressed stable equilibrium's property, traction cable arranges some drag-line parts be arranged side by side usually, schematically shows two drag-line part structures be arranged side by side in Fig. 3.
Be appreciated that in practical application, the drag-line part that three, four or other numbers are arranged side by side can be set as required.
Particularly, drag-line part comprises drag-line 30, the drag-line body 31 that this drag-line 30 specifically comprises two joints and is fixedly arranged on described in two between joint, and wherein, drag-line body 31 is at least two, and is arranged side by side.
More specifically, in two described joints, one is monaural joint 32, and another one is ears joint 33, is convenient to drag-line 30 and coordinates with the connection of miscellaneous part.
In concrete scheme, monaural joint 32, ears joint 33 are affixed by the mode of casting or suppress, not only easy but also reliable with drag-line body 31.Certainly, also can be affixed by other means.
As above, the changing-breadth system structure that this embodiment provides, when reducing the elastic potential energy that traction cable stores, can not affect the installation of traction cable.
Operationally, in hammer ram lifting process, the traction cable of changing-breadth system can store certain elastic potential energy to dynamic compaction machinery.The large I of this elastic potential energy is drawn by following formulae discovery:
Wherein:
K---stiffness factor;
Δ l---drag-line elongation;
F---the pulling force suffered by drag-line;
The length of l---drag-line;
E---modulus of elasticity;
The cross-sectional area of A---drag-line.
From above-mentioned formula, the length of the elastic potential energy that traction cable stores and drag-line is proportional, is inverse ratio with the cross-sectional area of drag-line.For dynamic compaction machinery, length, the modulus of elasticity difference of traction cable are also little, thus, determine that the variable of the elastic potential energy size that traction cable stores is the cross-sectional area of drag-line.
That is, in order to reduce the elastic potential energy that traction cable stores, avoid rammer unhooking moment, elastic potential energy acts on jib and makes jib and car load vibration, on the basis meeting dynamic compaction machinery work requirements, the effective measures that can take are the cross-sectional area increasing drag-line.
In background technology, the drag-line part forming traction cable only has a drag-line body, and its cross section is circular, and the monaural joint that its end is arranged, the size of ears joint and drag-line body are adaptive; If the demand of traction cable storage elasticity potential energy should be reduced, when increasing the cross-sectional area of traction cable, augmenting portion is only born by this root drag-line body, namely the diameter demand of answering of this root drag-line body increases, then monaural joint, ears joint also correspondingly radially extend out throughout the circumferential, and its volume and weight certainly will significantly increase, and cause the weight major part of drag-line to concentrate on the two ends of drag-line body, make troubles to the assembling of drag-line, affect the installation of traction cable.

In addition, due to the rope row formula design of drag-line 30, make monaural joint 32, the gain in weight of ears joint 33 is very little, so relative to background technology, this programme can when meeting installation requirements, increase the cross-sectional area of drag-line 30 as wide as possible, by suitably increasing the number of drag-line body 31, or suitably increase the cross-sectional area of drag-line body 31, or aforementioned two kinds of modes combined, thus under the prerequisite not affecting traction cable installation, during further reduction rammer unhooking, rocking of jib 10 and car load, improve the stressing conditions of parts such as jib 10 grade better, extend the application life of car load.
In concrete scheme, the cross-sectional area of each drag-line body 31 of drag-line 30 is identical, and so, monaural joint 32 suitable with it, the symmetrical configuration of ears joint 33 are even, avoid weight bias, and are convenient to processing.
The structure that drag-line has five drag-line bodies 31 to be arranged side by side is schematically shown in Fig. 5.
Be appreciated that, during practical application, the radical of the drag-line body 31 of drag-line 30 is not limited thereto, also can be set to three, four or the six roots of sensation etc., the cross-sectional area of drag-line body 31 also can design as required, considers and reduces the elastic potential energy of traction cable storage and convenient two factors of installation of traction cable.
Because the distance between jib 10 head and luffing assembly pulley 20 is longer, drag-line part is usually connected in series by some drag-lines 30 and forms; The drag-line part that two drag-lines 30 are connected in series is schematically shown in Fig. 3.
Should be appreciated that in practical application, drag-line part can be connected in series by other root drag-lines 30 such as three, five and form as required.
In concrete scheme, during serial connection, the monaural joint 32 of a drag-line 30 is connected with the ears joint 33 of another root drag-line 30.
Concrete connected mode can composition graphs 3 and Fig. 5 be understood, the monaural plate of the monaural joint 32 of a drag-line 30 is plugged between two otic placodes of the ears joint 33 of 30 of another root drag-line, the pin-and-hole of the monaural plate of monaural joint 32 and two otic placodes of ears joint 33 is alignd, first bearing pin 34 is inserted in the pin-and-hole of alignment, again the second bearing pin 35 is inserted in the end through hole of the first bearing pin 34, finally lock the second bearing pin 35 with cottor pin, guarantee that the connection of two drag-lines 30 is reliable.
