Embodiments for Carrying Out the Invention

[0009] As shown in FIGS. 1 to 10, a variable cross-section intelligent bridge truss erection machine includes a suspension beam 1, a main beam 6, an outer mold, a guide rail 2, and a reaction force mechanism. The suspension beam 1 is provided above the bridge and at the end surface of the cast section of the bridge. As a support member for the entire bridge truss erection machine, C-shaped members 16 are provided at both ends of the suspension beam 1. The ends of the C-shaped members 16 are folded back from both sides of the bridge below the wing plates. Thus, below the wing plates, the main beam 6, the hanging basket 12, etc. are provided at the ends of the C-shaped members 16. Specifically, two main beams 6 are detachably fixed to the ends of the C-shaped members 16. One end of the main beam 6 is extended to the cast section. The main beam 6 at the corresponding end is supported against the lower surface of the wing plate through the reaction force mechanism. The other end of the main beam 6 protrudes from the end surface of the cast section, connecting the hanging basket 12 and the outer mold. The outer mold is provided at the part protruding from the end surface of the cast section of the main beam 6. The contour of the inner wall of the outer mold conforms to the outer contour of the bridge, thereby forming the outer surface of the bridge by casting. An inner mold 18 is correspondingly provided inside the outer mold. The inner mold 18 forms the contour of the inner hole of the bridge, and together with the outer mold and the inner mold 18, a formwork for casting corresponding to the end surface of the bridge is formed. There are two guide rails 2, and the two guide rails 2 are correspondingly provided on both sides of the floor slab and are distributed in parallel. Preferably, the two guide rails 2 are located on both sides close to the wing plates of the top plate of the bridge, allowing the weight of the bridge truss erection machine to be borne by the bridge and avoiding excessive stress on the wing plates. The guide rails 2 are anchored to the floor slab through anchor pins, etc. Support seats 17 that can slide inside the guide rails 2 are respectively provided at both ends of the suspension beam 1, enabling the entire bridge to slide along the guide rails 2 and driving the movement of the entire bridge truss erection machine. The reaction force mechanism is provided corresponding to one end of the main beam 6 that is extended to the cast section of the bridge, pressing against the wing plate of the bridge along the longitudinal direction, and maintaining the balance of both ends of the main beam 6 by the opposition of the reaction force mechanism.In this embodiment, rollers are provided below the support base 17, and a hydraulic lever, a manual hoist or an electric hoist for driving the support base 17 is provided inside the guide rail 2, thereby driving the movement of the bridge truss erection machine.

[0010] The main beam 6 is mounted on the suspension beam 1 via the mounting member 21. The mounting member 21 has a block structure. An insertion hole (plug hole) 2102 adapted to the end of the C-shaped member 16 is provided in the middle of the mounting member 21. In this embodiment, the cross-section of the end of the C-shaped member 16 is square. At the end of the C-shaped member 16, the lower surface of the C-shaped member 16 reduces the end cross-section of the C-shaped member 16 by a smooth transition. Without affecting the strength of the suspension beam 1, the size of the insertion hole 2102 is made as small as possible. The end of the C-shaped member 16 approaches the side plate of the bridge after passing through the corresponding insertion hole 2102. Below the mounting member 21, a hinging station 2101 corresponding to the main beam 6 is provided. The hinging station 2101 is a groove-like structure at the bottom of the mounting member 21. The main beam 6 is positioned at the hinging station 2101 via a hinge shaft, thereby fixing the main beam 6 to the suspension beam 1.

[0011] First bolts 3 are provided on both sides of the mounting member 21. The lower ends of the two first bolts 3 are fixed to both sides of the mounting member 21. The upper ends of the first bolts 3 extend upward from both sides of the suspension beam 1 after passing through the wing plate of the bridge upward. A first support member 24 is provided above the suspension beam 1. Both ends of the first support member 24 are detachably connected to the two first bolts 3 respectively, thereby applying the mounting member 21 to the suspension beam 1 via the first bolts 3 and ensuring that the force received by the main beam 6 is applied to the suspension beam 1 body by applying a pre-stress, and avoiding the force deformation of the C-shaped member 16.

[0012] The reaction mechanism includes the opposing wheels 4 and the opposing element 5. Both the opposing wheels 4 and the opposing element 5 connect the main beam 6 via a self-locking cylinder 20. In the placed state, the lower surface of the wing plate is pressed against via the opposing element 5. When movement is required, the opposing element 5 retracts and presses against the lower surface of the wing plate via the opposing wheels 4, thereby forming rolling friction. The opposing element 5 is fixedly connected to the corresponding self-locking cylinder 20. The upper surface of the opposing element 5 is an inclined surface corresponding to the wing plate of the bridge. In the normal state, it is in close contact with the lower surface of the wing plate, and the stability of the opposition can be guaranteed. To ensure that the opposing wheels 4 are in close contact with the lower surface of the wing plate during the movement process of the bridge erection machine, the opposing wheels 4 are provided on hinges. Specifically, the two opposing wheels 4 are connected to the same cam groove 29. The two opposing wheels 4 are distributed in the length direction of the bridge, so that they can move along the length direction of the bridge along the lower surface of the wing plate. The two cam grooves 29 are hinge-connected to the two sides corresponding to the width direction of the bridge of the wheel box 30 and rotate in a plane located in the length direction of the bridge during movement. The wheel box 30 is hinge-connected to the upper end of the self-locking cylinder 20 and rotates in a plane located in the width direction of the bridge, thereby forming a two-dimensional angle rotation to ensure that the opposing wheels 4 are in close contact with the lower surface of the wing plate during the movement process of the bridge erection machine.

However, the shape of the wing mold 11 conforms to the shape of the lower surface of the wing plate, the side mold 10 conforms to the shape of the outer wall of the web of the bridge, the bottom mold is connected to the bottom of the side mold 10, thereby forming a complete outer mold. One end protruding from the placed section of the main beam 6 is correspondingly connected to the end frame 14, and the end frame 14 is welded to a channel steel or an angle steel. It has a front upper crossbeam for connecting the end portions of at least two main beams 6. The end frame 14 is fixed to the end portion of the main beam 6 by screw bolts.

Specifically, it can connect the front upper crossbeam of the end frame 14. The other side of the hanging basket 12 is connected directly below the connection point of the suspension beam 1 of the side frame via two second bolts 13. The bottom mold is lifted by the upward traction of the second bolts 13 to ensure the connection between the bottom mold and the side mold 10 and the wing mold 11.

[0014] To apply a continuously variable cross-section bridge, for the inclined surface of the variable cross-section bottom, the second bolt 13 can be adjusted according to actual needs, thereby causing the corresponding inclination of the hanging basket 12 and the bottom mold, and enabling the construction of the variable cross-section.
