Abstract
A center shaft capable of floating flexible self-adaptive connection is connected with a machine body and a rotating platform in the running and rotating mechanism of a hydraulic static pile driver, a lug boss with a spherical surface is formed at one end of the center shaft, and a snap ring groove is formed at the other end thereof; the lug boss with a spherical surface on the center shaft combines and forms an universal floating connection with the spherical face on a ballcup; the center shaft passes through the center hole of the rotating platform, and then two semicircular snap-gauges are stuck in the snap ring groove of the center shaft for serving the axial spacing function; and due to the universality and the floating flexibility featured in spherical face combination and connection, as the hydraulic static pile driver rotates, the center shaft changes position self-adaptively according to the stress status, and adjusts automatically the rotating center distance to improve the stress status, thereby compensating for the erection stress produced by the mismachining tolerance of components and compensating for the displacement as a result of the machine body dropping on or departing from the platform during the rotation as well.
Description
Affiliated technical field
The utility model relates in a kind of hydraulic static pile pressing machine walking slew gear, works the central axis that connects fuselage and revolving dial effect.
Background technology
Hydraulic static pile pressing machine is the desirable stake construction equipment of preformed pile static pressure worker method, is widely used in the pile foundation engineering constructions such as precast square pile, pile tube and H type abnormal shape piling bar.Central axis in the hydraulic static pile pressing machine walking slew gear works to connect fuselage and revolving dial.At present, the central axis in the hydraulic static pile pressing machine walking slew gear all is to be rigidly fixed on the fuselage.Because hydraulic static pile pressing machine working environment complexity, stress polytropism and complexity, traditional central axis center to center distance when hydraulic static pile pressing machine turns round that is rigidly connected can not be regulated voluntarily, cause the central axis force-bearing situation abominable, central axis often destroys because of tired, influence the hydraulic static pile pressing machine efficiency of construction, increase maintenance, use cost.
Summary of the invention
For the central axis center to center distance when hydraulic static pile pressing machine turns round that is rigidly connected that overcomes existing hydraulic static pile pressing machine can not be regulated voluntarily, cause the central axis force-bearing situation abominable, central axis is often because of the tired deficiency of destroying, the utility model provides a kind of unsteady flexible self adaptation to connect central axis, self adaptation was regulated the orientation of central axis when this central axis turned round at hydraulic static pile pressing machine, stress when improving the central axis revolution, central axis only is subjected to axial tensile force, has prolonged the application life of central axis.
The technical scheme that its technical problem that solves the utility model adopts is: central axle designs is become a kind of structure cleverly, and an end is designed to the boss of the face of dribbling, and other end design has annular groove.On fuselage, weld a ball cup with the revolving dial junction, the center design of revolving dial has centre bore, assembly relation is for the hole of face being inserted into the central axis slave on the ball cup on the fuselage on one's body, the boss of dribbling face and a kind of universal, unsteady connection of the sphere cooperation formation on the ball cup on the central axis, central axis passes the centre bore of revolving dial again, be stuck in the annular groove of central axis with two semicircular clamps then, play axial limiting.The universal property that utilizes sphere to be connected, central axis can be regulated centre of gyration distance voluntarily according to the orientation of force-bearing situation adaptively modifying central axis during the hydraulic static pile pressing machine revolution, improves stress.The connection of this central axis still is a kind of unsteady connection, the erection stress that can offset zero component processing error causes, and fuselage drops on or the displacement when leaving revolving dial in the time of can also compensating revolution.
The beneficial effects of the utility model are that central axis can be regulated centre of gyration distance voluntarily according to the orientation of force-bearing situation adaptively modifying central axis during the hydraulic static pile pressing machine revolution, improves stress.The erection stress that can offset zero component processing error causes, fuselage drops on or the displacement when leaving revolving dial in the time of can also compensating revolution.Simple in structure, installation, easy removal, central axis long service life.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a central axis assembling drawing of the present utility model.
Fig. 2 is center spindle structure figure.
Among the figure: 1. fuselage, 2. ball cup, 3. central axis, 4. revolving dial, 5. clamp.
The specific embodiment
In Fig. 1, central axis (3) is designed to a kind of structure cleverly, an end is designed to the boss of the face of dribbling, and other end design has annular groove.Go up and revolving dial (a 4) junction welding ball cup (2) at fuselage (1), welding one seamless steel pipe on the ball cup, strengthen the intensity at the stressed place of fuselage (1), seamless steel pipe forms installing hole and makes things convenient for mounting center axle (3), the center design of revolving dial (4) has centre bore, assembly relation is for the hole of face being inserted into central axis (3) slave on the ball cup on the fuselage on one's body, it is a kind of universal that the boss of dribbling face cooperates formation on the central axis with sphere on the ball cup (2), float and connect, central axis passes the centre bore of revolving dial again, use two semicircular clamps (5) to be stuck in the annular groove of central axis then, play axial limiting.The universal property that utilizes sphere to be connected, central axis can be regulated centre of gyration distance voluntarily according to the orientation of force-bearing situation adaptively modifying central axis during the hydraulic static pile pressing machine revolution, improves stress.The design of the bottom surface of central axis (3) lower end clamp and revolving dial (4) has certain clearance in addition, make a kind of unsteady connection of being connected to form of central axis (3), the erection stress that can offset zero component processing error causes, fuselage drops on or the displacement when leaving revolving dial in the time of can also compensating revolution.
Claims (3)
1. the flexible self adaptation of floating connects central axis, in hydraulic static pile pressing machine walking slew gear, the flexible self adaptation of floating between fuselage and the revolving dial is connected central axis, it is characterized in that: an end of central axis is designed to the boss of the face of dribbling, other end design has annular groove, the sphere of the ball cup on the central axis on boss and the fuselage of dribbling face cooperate form a kind ofly float, flexibility, self adaptation be connected, central axis passes the centre bore of revolving dial, be stuck in the annular groove of central axis axial limiting with two semicircular clamps.
2. central axis according to claim 1, it is characterized in that: central axis one end is designed to the boss of the face of dribbling, the sphere boss is connected to form the spherical floating self adaptation with fuselage solder sphere headstock and is connected, fuselage ball cup and fuselage welding, design and installation hole above the fuselage ball cup, installing hole welding seamless steel pipe.
3. central axis according to claim 1 is characterized in that the clamp annular groove that central axis other end design and installation clamp is used, and flexibly connects with semicircular clamp.
