Background technology
Highway in China development is rapid, and especially the Large scale construction of speedway experienced by development during the last ten years, has achieved significant achievement.Along with the use of bridge, the bearing of Partial Bridges is aging or damage, and needs to change, and the speedway had at present has entered repaiies the phase greatly, has a great deal of bridge to need repairing every year.Simultaneously in the process of bridge construction, also need the girder of bridge to support, the girder of building to allow cement solidifies at preposition.Existing method for supporting mainly utilizes steel, plank or wooden unit to set up framed bent and directly supports, and framed bent distortion easily occurs these class methods, causes girder that trickle distortion occurs.Bridge is that one is erected in rivers,lakes and seas, and for the building that traffic etc. can pass through smoothly, be generally made up of superstructure, substructure and attached structure, superstructure mainly refers to bridge span structure and support system; Substructure comprises abutment, bridge pier and basis; Attached structure then refers to transition slab at bridge head, truncated cone banking, shore protection, training works etc.Existing bridge is when constructing, and also have and adopt lift-up device to carry out auxiliary construction, according to the structure size of bridge, the lift-up device used is also different.Due to ground, the below uneven of a lot of bridge, or vertical ground is not suitable for placing Lifting Equipment, needs can realize Lifting Equipment level-off or carry out the jacking in oblique orientation, but existing bridge construction lift-up device can not in the jacking work in hogwallow level-off and oblique orientation.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of bridge construction lift-up device, jacking operation can be carried out at hogwallow, the lifting operation at angle of inclination can be carried out simultaneously.
The technical scheme that the present invention takes is:
A kind of bridge construction lift-up device, comprise hydraulic telescopic device, base, hydraulic telescopic device top is provided with top board, top board is connected by rotatable rotating shaft with hydraulic telescopic device top, hydraulic telescopic device bottom is connected by axis of rotation with base, base is provided with telescopic supporting rod, and base bottom is provided with at least two adjustable support legs.
Each adjustable support leg comprises fixed block, threaded rod, pad, and threaded rod top is by being arranged on screwed hole on fixed block and fixed block Screw assembly, and threaded rod lower connection pad sheet, threaded rod is provided with regulating nut.
Hydraulic telescopic device and base junction, be provided with the angle scale of band angle index line.
Axis of rotation comprises middle screw rod and the hold-down nut at two ends, and the hold-down nut at two ends moves along the screw rod of centre.
Top board take rotating shaft as fulcrum, can do 180 ° of rotations.
A kind of bridge construction lift-up device of the present invention, compared with prior art, has following advantage:
1), due to base bottom being provided with at least two adjustable support legs, by regulating adjustable support leg, thus improving support force and the stability of base.
2), hydraulic telescopic device is connected by axis of rotation with base, thus realize the inclination of hydraulic telescopic device, be provided with hold-down nut simultaneously, female thus the constant tilt angle of rotary fixing screw, be provided with telescopic supporting rod simultaneously, for support hydraulic pressure stretching device, realize the use of lift-up device under angle of inclination.
3), this device can carry out jacking operation at hogwallow, can carry out the lifting operation at angle of inclination simultaneously.

Fig. 2 is apparatus of the present invention inclination operation schematic diagram;
Fig. 3 is the revolute axes configuration schematic diagram of apparatus of the present invention;
Fig. 4 is the adjustable support leg structural representation of apparatus of the present invention.
Detailed description of the invention
As shown in Fig. 1 ~ Fig. 4, a kind of bridge construction lift-up device, comprises hydraulic telescopic device 1, base 2, hydraulic telescopic device 1 top is provided with top board 3, top board 3 is connected by rotatable rotating shaft 4 with hydraulic telescopic device 1 top, and top board 3 for fulcrum, can do 180 ° of rotations with rotating shaft 4.Hydraulic telescopic device 1 bottom is connected by axis of rotation 5 with base 2, base 2 is provided with telescopic supporting rod 6, is provided with at least two adjustable support legs 7 bottom base 2.Each adjustable support leg 7 comprises fixed block 14, threaded rod 8, pad 13, fixed block 14 is welded on bottom base 2, threaded rod 8 top is by being arranged on screwed hole on fixed block 14 and fixed block 14 Screw assembly, and threaded rod 8 lower connection pad sheet 13, threaded rod 8 is provided with regulating nut 9.
Hydraulic telescopic device 1 and base 2 junction, be provided with the angle scale 10 of band angle index line.Axis of rotation 5 comprises middle screw rod 11 and the hold-down nut 12 at two ends, and the hold-down nut 12 at two ends moves along the screw rod 11 of centre.
When reality uses, when ground uneven, when base 2 is placed on the ground of hollow, regulate the regulating nut 9 of adjustable support leg 7, threaded rod 8 precession or back-out fixed block 14, thus the length of adjustable multiple adjustable support leg 7, multiple pad 13 is allowed directly to drop on the ground of hollow, when using lift-up device, completely the pad 13 of each adjustable support leg 7 can be implemented on rugged hogwallow, thus improve the support force of lift-up device.
When the oblique orientation jacking of needs, the hold-down nut 12 at two ends on axis of rotation 5 is unclamped, then the angle of inclination of hydraulic telescopic device 1 is regulated, hydraulic telescopic device 1 and base 2 junction are provided with the angle scale 10 of band angle index line, angle of inclination can be observed out intuitively, when arriving the angle preset, rotary fixing screw mother 12, hydraulic telescopic device 1 is made to be fixed on base 2, open telescopic supporting rod 6 simultaneously, then telescopic supporting rod 6 is extended, telescopic supporting rod 6 is made to withstand hydraulic telescopic device 1, thus make hydraulic telescopic device 1 be fixed on this angle, as shown in Figure 2, regulate the angle of top board 3 simultaneously, make position and the ground level of top board 3.
