The invention relates to an anti-sedimentation bridge girder erection machine front supporting leg device and a construction method thereof.The anti-sedimentation bridge girder erection machine front supporting leg device comprises a main beam, a lifting mechanism and a supporting rod, the lifting mechanism is provided with a first connecting part and a second connecting part, the supporting rod is provided with a first connecting matching part and a second connecting matching part, and when the first connecting part is connected with the first connecting matching part, the second connecting matching part is matched with the first connecting matching part; when the second connecting part and the second connecting matching part are disconnected, the supporting rods are static relative to the lifting mechanism, and the second connecting part and the second connecting matching part are connected, the first connecting part and the first connecting matching part are disconnected, the lifting mechanism drives the supporting rods to move downwards, automatic plug pin mechanisms are arranged on the supporting rods, and a movable beam is arranged between the two supporting rods. According to the anti-sedimentation bridge girder erection machine front supporting leg device and the construction method thereof, the supporting rods are pressed by the oil cylinders to be inserted into a seabed or a riverbed to avoid sedimentation of the bridge girder erection machine during construction, the bottom ground supporting area is increased through the movable beams, stress is uniform and reasonable, safety and reliability are achieved, and the safety and stability of the bridge girder erection machine are enhanced.

This invention relates to the field of bridge construction technology, and discloses a support system and construction method for a mainline bridge cap beam. The system includes: a cap beam formwork support, which provides a supporting foundation for the mainline bridge cap beam formwork; the cap beam formwork support includes: a first cap beam formwork support and a second cap beam formwork support; multiple bracket structures connected to the existing mainline bridge piers; both ends of the bracket structures extend outward beyond the mainline bridge piers, forming cantilever ends; the first cap beam formwork support is erected on the cantilever ends of the bracket structures, with its top providing support for the mainline bridge cap beam formwork; the second cap beam formwork support is erected above the existing auxiliary road bridge deck, with its top providing support for the mainline bridge cap beam formwork; the first and second cap beam formwork supports are connected to form an integrated support system. Because the cap beam formwork support does not occupy the river channel area under the bridge, it ensures that the river's flood control and navigation functions are not affected; and it effectively shortens the construction period.

The utility model provides a kind of ball pin dismounting tool, belong to mechanical dismounting tool technical field, it includes screw rod, cross bar, calliper, adjusting nut and press-down platform, cross bar is equipped with calliper and slidingly connected, adjusting nut is equipped with screw rod and is fixed with cross bar, press-down platform is equipped with screw rod bottom end.Working, calliper is connected axle bridge knuckle, rotates screw rod and makes press-down platform press down ball pin, calliper is on top axle bridge knuckle, realize the separation of both.The tool is convenient and labor-saving, can be stable force, reduce component damage, adapt to a variety of specifications ball pin, structure stable and reliable, prolong service life.

The utility model relates to the technical field of snow melting machines, and discloses a snow melting machine double-stirring blade which comprises an installation disc and an end disc, two stirring blades are arranged between the installation disc and the end disc, the installation disc is in a disc shape, two symmetrically-distributed connecting plates are arranged at the end, away from the end disc, of the installation disc, the two connecting plates are in fan shapes with radians, and the two stirring blades are arranged on the installation disc. A connecting block is arranged in the middle of the end, away from the end disc, of the mounting disc, a mounting block is arranged at the other end of the mounting disc, and a mounting groove is formed in the middle of one side of the mounting block. According to the double stirring blades of the snow melting machine, the stirring efficiency and the snow melting uniformity are remarkably improved through the two spiral stirring blades which are arranged between the mounting disc and the end disc in an alternating mode, the mounting disc is designed in a disc shape and is provided with the two symmetrically-distributed connecting plates with the fan-shaped included angle ranging from 80 degrees to 130 degrees, and by means of the design, the stability of the structure is enhanced, and the snow melting efficiency is improved. And the mounting layout of the stirring blades is also optimized.

The utility model discloses a horizontal support and steel beam connection reinforcing member in constructional engineering, which comprises a steel beam, horizontal beams are fixedly connected to two sides of the steel beam, two angle brace connecting plates are arranged on the front side and the rear side of the steel beam in a penetrating manner, and the two angle brace connecting plates are fixedly connected with the steel beam through bolts. Two reinforcing plates are arranged on the front sides and the rear sides of the two horizontal beams correspondingly, mounting plates are attached to one sides of the four reinforcing plates correspondingly, connecting pieces are fixedly connected to the left side and the right side of the steel beam correspondingly, U-shaped plates are fixedly connected to the tops of the two horizontal beams correspondingly, and inclined rods are fixedly connected to the sides, opposite to the U-shaped plates, of the connecting pieces correspondingly. Supporting pieces are arranged at the bottoms of the two horizontal beams. Through the cooperative use of the angle brace connecting plate, the reinforcing plate and the inclined rod, the joint of the connection of the steel beam and the horizontal beam is more stable, the overall stability of the steel beam and the horizontal beam is effectively enhanced, and the fatigue damage of the connection of the steel beam and the horizontal beam caused by local stress concentration can be avoided.
