Abstract
The utility model discloses a slewing bearing device for a hydraulic static pile presser, which comprises a slewing table and a pile presser base plate. The slewing table is rotatably supported on the pile presser base plate through a slewing support, and a balance support guide wheel is further supported between the slewing table and the pile presser base plate and positioned outside the slewing support. The balance support guide wheel comprises a guide wheel seat and a roller which is supported on a guide wheel shaft through a bearing, the guide wheel shaft is fixedly mounted on the guide wheel seat which is fixedly mounted on the lower side of the slewing table, and the roller is in rolling contact with a plate surface of the pile presser base plate. The slewing bearing device for the hydraulic static pile presser is reasonable in stress, balanced in slewing, high in bearing capacity, and widely applicable to engineering machinery such as hydraulic static pile pressers, slewing pile frames and the like.
Description
Technical field
The utility model relates to a kind of building pile foundation engineering construction machinery, relates in particular to the improvement of hydraulic static piling machine slew gear.
Background technology
Hydraulic static piling machine is because characteristics such as its high efficiency, noiseless, low pollution obtain application more and more widely.The static piling machine of wherein taking back rotating function is comparatively common walking hydraulic pressure pile sinking equipment, and such pile sinking machine can oneself be walked in the workplace, promptly can carry out vertical or horizontal moving, and gyration.Its laterally or vertically move mainly be by its long ship structure and short ship structure alternately land liftoff carrying out before and after or about mobile; Gyration then is that the revolving dial with the pile sinking machine fuselage is installed on the pile sinking machine chassis by pivoting support, makes a machine fuselage can a wraparound change a supporting center and do gyration.
Because revolving dial has been concentrated deadweight of pile sinking fuselage and counterweight, this huge stake machine weight all is passed on the machine chassis by pivoting support, and in the pile sinking operation during revolving dial rotation, the support oil cylinder of platform will be packed up and liftoff, its center of gravity often departs from the centre of gyration, forms cantilever beam structures.Pivoting support not only will bear huge axial force and footpath guide power, but also bears huge overturning moment, makes the stressing conditions severe exacerbation of pivoting support, be subjected to force unbalance, turn round dumbly, cause turning round the damage of parts easily, shorten the application life and the operating efficiency of swinging pile sinking machine.
The utility model content
At the above-mentioned deficiency of existing in prior technology, technical problem to be solved in the utility model be stressed rationally, turn round hydraulic static piling machine rotary supporting device stably.
In order to solve the problems of the technologies described above, hydraulic static piling machine rotary supporting device of the present utility model, comprise revolving dial and stake machine chassis, this revolving dial passes through the pivoting support rotatably support on stake machine chassis, also be supported with the balanced support guide wheel between described revolving dial and the stake machine chassis, this balanced support guide wheel is positioned at the outside of pivoting support.
After adopting said structure, owing to be supported with the balanced support guide wheel between revolving dial and the stake machine chassis, and the balanced support guide wheel is positioned at the outside of pivoting support, revolving dial is supported on the machine chassis with the multi-support point, the revolving dial force-bearing situation forms freely supported structure, and pivoting support only bears axial force, has fundamentally avoided the generation of overturning moment, more reasonable stress, supporting capacity is stronger.Also, make revolving dial steadily flexible, the longer service life of pivoting support owing to adopted the balanced support guide wheel.This structure also has simple in structure, uses easily manufactured advantage.
Description of drawings
Below in conjunction with the drawings and specific embodiments hydraulic static piling machine rotary supporting device of the present utility model is further described.
Fig. 1 is the structural representation of a kind of specific embodiment of the utility model hydraulic static piling machine rotary supporting device.
Fig. 2 is a kind of structural representation of balanced support guide wheel in the utility model;
Among the figure, 1-revolving dial, 2-device for revolving and driving, 3-pivoting support, 4-balanced support guide wheel, 5-stake machine chassis, 6-running roller, 7-bearing, 8-guide wheel shaft, 9-wheel stand.
The specific embodiment
In rotary supporting device shown in Figure 1, by pivoting support 3 rotatably supports revolving dial 1 is arranged on the stake machine chassis 5, this revolving dial 1 is provided with pile sinking door frame, crane, hydraulic system and counterweight etc.Pivoting support 3 adopts the building machinery pivoting support bearing that has bull gear commonly used, and device for revolving and driving 2 drives pivoting support 3 and revolving dial 1 rotation by the bull gear of pivoting support 3.Device for revolving and driving 2 is motor or hydraulic motor.
Be evenly equipped with four balanced support guide wheels 4 at the downside of revolving dial 1 along the outside of pivoting support 3.This balanced support guide wheel 4 comprises wheel stand 9 and running roller 6, core at running roller 6 is provided with dead eye, two bearings 7 are housed in the dead eye, these two bearings 7 all are loaded on the guide wheel shaft 8, and guide wheel shaft 8 is installed on the wheel stand 9, wheel stand 9 is fixedly installed in the downside of revolving dial 1, and running roller 6 rolling bearings are on the card on stake machine chassis 5.
Rotary supporting device of the present utility model is not only applicable to hydraulic static piling machine, and is suitable for the various piling machinerys such as pile frame that have revolving dial.Balanced support guide wheel 4 also is not limited to be fixedly installed in the downside of revolving dial 1 simultaneously, can also be to be fixedly installed on the machine chassis 5, and its running roller 6 rollings are contacted with the downside of revolving dial 1.
