Description

Technical Field

[0002] At present, PHC or steel pipe piles are generally used for the pile foundation construction of bridge piers in water bridge construction. The traditional process is to lay temporary construction access roads or build trestles or use pile-driving boats on the water to drive pipe piles. However, in nature reserves, swamps, tidal flats, long-period wave coastal construction, mountain streams and urban built-up areas, due to the rigid constraints of environmental protection, limited space, complex geological environment and other reasons, there are no conditions for building construction access roads, and it is impossible to use existing bridge erection machines and conventional processes to complete the construction of bridge piers. In order to overcome the above restrictions and meet the construction needs, it is necessary to improve the existing bridge erection machines. Or design a new type of piling and bridge erection integrated machine, which has the function of sinking piles for pier pile foundations, adapts to the horizontal transportation of pile foundations, cap beams and box beams by bridge erection machines, and drives and penetrates pile foundations after the bridge erection machine passes through the hole to the pile position. After the cap beam is erected on the pile foundation, the concrete box beam of the bridge deck is laid in place to meet the requirements of integrated construction. Summary of the invention

Under the control of the operating system, the beam longitudinal movement device pushes the main beam (22) of the frame (2) to move longitudinally with the support of two pairs of reverse-hanging walking devices (31) of the second legs (4); the bottom of the second transverse movement beam (46) is fixed with two second columns (47) and two support screws (38) and then supported on the external cap beam; the anchoring device (49) anchors the bottom of the support screws (38) to the external cap beam respectively; when the second leg (4) is separated from the external concrete beam, the reverse-hanging walking device (31) is operated by the operating system to move longitudinally under the main beam (22) of the frame (2), so that the main beam (22) of the frame (2) can be supported by the second leg (4) at different positions on the external concrete beam; The first leg (3) is arranged at the front end of the main beam (22) of the frame (2) and is located in front of the second leg (4); each of the first leg units (30) is placed on two chords at the bottom of the two main beams (22) through a pair of reverse hanging walking devices (31); the lower end of the reverse hanging walking device (31) is fixed with a first column (37), a telescopic sleeve device (39) and a supporting screw (38); the control system controls each pair of reverse hanging walking devices (31) respectively so that each first leg unit (30) moves longitudinally along the main beam (22) to the side of the external cap beam, and each first leg unit (30) is fixed to the external cap beam through the pier side bracket (32); The pile driver (7) is arranged in a cavity between the front parts of the two main beams (22) of the frame (2); when the front crane (1) and the rear crane (1') lift the external pipe piles and transport them forward along the two main beams (22) of the frame (2), the pile driver (7) is tilted backward and is located between the two main beams (22) in a horizontal state; when the pile driver (7) and its external pipe piles are completely turned forward to a vertical position, they enter a standby state, and the pile driver (7) is started by the operating system to drive the external pipe piles into the ground; The construction platform (8) is suspended in a track between two main beams (22) of the frame (2) and is located behind the pile driver (7). The construction platform (8) is moved longitudinally and lifted vertically below the frame (2) through the control system. The operating system controls the front crane (1) and the rear crane (1') to move longitudinally along the two main beams (22) of the frame (2) by operating the crane longitudinal movement mechanism (12), controls the front crane (1) and the rear crane (1') to move transversely along the crane transverse beam (14) by operating the crane transverse movement mechanism (13), and controls the front crane hoist (15) of the front crane (1) and the rear crane (1') to move up and down by operating the lifting system (11), thereby completing the transportation of external pipe piles, cap beams and concrete beams into place.

2. The piling and beam erecting machine according to claim 1, characterized in that The supporting device (59) of the fourth leg (5) adopts four sets of screw mechanisms, which can be adjusted individually to ensure that the fourth leg (5) is supported on the external concrete beam with longitudinal and transverse slopes.

3. The piling and beam erecting machine according to claim 1, characterized in that The height adjustment telescopic device (58) of the fourth leg (5) is lifted by an oil cylinder and supported together with the two brackets (52) at the bottom of the main beam (22) of the frame (2), so that the frame (2) can move longitudinally and reach the pile position after passing through the hole when the third leg (4') is separated from the external concrete beam.

4. The piling and beam erecting machine according to claim 1, characterized in that The first leg (3) has two supporting screws (38), which are supported on the external cap beam in a mutually offset manner by an independent adjustment method, so that the frame (2) can move longitudinally on the curved external concrete beam and reach the pile position after passing through the hole.
