Description

One kind building piling machine

Technical field

The utility model relates generally to technical field of buildings, and piling machine is built more particularly to one kind.

Background technology

Hydraulic vibration piling machine is a kind of to be widely used in the heavy of the various foundation construction engineerings such as urban construction, bridge, harbour Pile pulling construction machinery, it is generally matched with crane or pile frame, and operation is pulled out suitable for all kinds of steel sheet piles and the heavy of steel-pipe pile, Also it can be used for cast-in-place concrete pile, lime

Polytype basement process operations such as stake, husky stake, stake is thrown into soil when building pavement construction with piling machine In, if using static pressed pile, then very big power is needed, so that piling machinery is excessively huge, difficulty is caused to construction. And vibreatory hammer can be driven piles using the centrifugal force that the rotation of eccentric block produces, the soil that this process overcomes hinders Power very little, it is only necessary to which more small-sized machinery is with regard to that can solve the problems, such as.

But hydraulic vibration piling machine of the prior art, drive soil resonance due to needing ceaselessly to vibrate, it is possible to Certain infringement is caused to adjacent building or works, Theory of Vibration shows, when the frequency and Adjacent Buildings of mechanical oscillation When frequency is consistent, resonance can be produced, the powerful vibratory impulse of resonance can produce destruction to Adjacent Buildings.

The content of the invention

Occur altogether with Adjacent Buildings in view of the deficienciess of the prior art, the utility model aims to provide one kind and is avoided that The hydraulic vibration piling machine to shake.

To achieve the above object, the utility model provides following technical solution：

One kind building piling machine, includes adjutage, is fixed on exterior excavator, be hung with and shake on the adjutage Dynamic device, the vibrator include hydraulic motor, two gears being arranged side by side are provided with the bottom of the hydraulic motor, by Described two gears of fluid motor-driven rotate backward, and gear hole is centrally formed with gear, fixed in the gear hole Gear shaft, it is characterised in that：Eccentric block is arranged with the gear shaft of described two gears, the eccentric block can be with described Gear shaft rotates together, and horizontal centrifugal force caused by two eccentric blocks rotations can cancel out each other, in the lower section of the eccentric block Pile chuck is connected to by bearing；Resilient suspension is provided between the vibrator and the adjutage.

As the improvement of the utility model, the resilient suspension includes suspended axle, and the top of the suspended axle passes through spiral shell Nail is connected with the adjutage, and the bottom of the suspended axle is extended in the hydraulic motor and formed with boss, described outstanding Spring is arranged with hanging scroll, the spring can be clamped by the inner wall of the hydraulic motor and the boss.

As further improvement of the utility model, the resilient suspension further comprises rubber strip, and the two of the rubber strip End is separately fixed in the both sidewalls of the hydraulic motor and fixed position is below the height of the boss, the rubber strip Middle part around being located on the boss.

As the preferred of the utility model, the pile chuck includes two collets, and one of collet is fixed, separately Through hole is offered on an outer collet, bolt, the bolt are provided with the fixed fixture in bearing bottom, the fixture Extended in through the through hole outer.

As the concrete technical scheme of the utility model, the weight of the eccentric block is by the direction court away from the gear shaft It is gradually reduced to the direction close to the gear shaft.

Compared with prior art, the utility model has the advantage of：Resilient suspension is set by side on a shaker, as far as possible The vibration of vibrator is reduced to adjutage and exterior excavator（Pile frame）Have an impact, thus reduce the shadow to surrounding buildings Ring.

Brief description of the drawings

Fig. 1 is the structure diagram that piling machine is built in the utility model embodiment.

Embodiment

The embodiment of building scaffold in the utility model is described further referring to the drawings.

As shown in drawings, the present embodiment is a kind of building piling machine, includes adjutage 1, be fixed on exterior excavator 2 or On other building haulage vehicles of person, vibrator 3 is hung with adjutage, vibrator includes hydraulic motor 31, hydraulic motor The engine being exactly commonly called as, since its principle is largely disclosed in the prior art, and it is played in the present embodiment Effect be to provide driving force to gear described hereinafter, this point and the duty of engine of the prior art are identical, therefore Its operation principle is not specifically addressed in the present embodiment.

Hydraulic motor has two output shafts, and a gear 32, two outputs are respectively and fixedly provided with the bottom of two output shafts Gear on axis is rotated backward in being arranged side by side by two gears of fluid motor-driven, i.e., when a gear rotates clockwise, Another gear is to rotate counterclockwise, they can be intermeshed, by the occluding relation between gear by a gear band Move another gear to rotate, can also be separated from each other to form gap, drive two gears individually to rotate by output shaft.In gear Gear hole is centrally formed with, the fixed gear shaft 321 in the gear hole, is arranged with partially on the gear shaft of two gears Heart block 33, eccentric block can be rotated with gear shaft, and the Mass Distribution of eccentric block is non-uniform, by that away from gear shaft End is gradually reduced towards close to one end of gear shaft, thus when gear shaft drives eccentric block to rotate, can produce it is outside and to Under centrifugal force effect, this centrifugal force can do horizontal and vertical vibration with movable gear shaft, since two eccentric blocks are reverse Rotate, therefore they can cancel out each other in the horizontal centrifugal force that horizontal plane produces, and thereby eliminate whole vibrator and exist Horizontal vibration（The vibration of vibrator transverse direction is substantially a kind of invalid vibration）, and exacerbate the extensional vibration width of vibrator Degree.The rotation of eccentric block just drives whole vibrator to produce up-down vibration, after soil is subject to forced vibration, its internal friction Reduce, intensity decreases, when forced vibration frequency is identical with the soil natural frequency of vibration, soil resonance enables stake lighter Ground is sunk in soil

Pile chuck 35 is connected to by bearing 34 in the lower section of eccentric block；Set between vibrator and adjutage flexible Suspension 4.Resilient suspension includes suspended axle 41, and the top of suspended axle is connected by screw 5 with adjutage, and the bottom of suspended axle is prolonged It is stretched outside in hydraulic motor and formed with boss 411, spring 6 is arranged with suspended axle, spring is compressed in the interior of hydraulic motor Between wall and boss.Resilient suspension further comprises rubber strip 42, and the both ends of rubber strip are separately fixed at two surface sides of hydraulic motor On wall and fixed position is below the height of boss, and the middle part of rubber strip is around being located on boss.By this structure design, make When vertical vibrating occurs for proper vibrator, the dynamic respons to suspended axle can be reduced by spring and rubber strip, and then reduce and prolong The vibration of semi-girder and exterior excavator.

Pile chuck is for will need to squeeze into the component of timber or steel bar clamping in soil or ground.It includes two Collet 351, one of collet is fixed, and through hole is offered on another collet, in the fixed fixture 7 in bearing bottom, Bolt 71 is provided with the fixture, bolt extends in outside through the through hole, can be by two collets when tightening bolt 71 Close up, so that timber be clamped, conversely, when unclamping bolt, then two collets can be separated, so as to release the folder to timber Hold.

The above makes the preferred embodiment of the utility model, does not depart from for those of ordinary skill in the art On the premise of the utility model principle, some variations and modifications can also be made, these also should be regarded as the protection of the utility model Scope.
