Description

Stepless adjustable ball-joint multi-leg bridge erecting machine front traversing track system

technical field

Background technique

In recent years, my country's highway infrastructure has developed rapidly. A large number of highways, especially high-grade highways, are under construction or planned to be constructed. A large number of bridges are used to cross valleys and rivers, and most of the bridges are prefabricated and then transported to the site for erection and installation to ensure the construction quality of the bridges. Most of these bridges are erected with double-guided girder erecting machines.

The front traversing track of the double guide girder bridge erecting machine is placed on the front pier cover beam, and its lower support pad structure is the external structure of the bridge erection machine, but its role is very critical. Most of the support structure adopts short sleepers (or square timber) stacked vertically and horizontally on the cover beam to form a square support pier. The support piers are arranged at a certain horizontal distance. When the cover beam has a transverse slope, each sleeper supports The pier is treated with special-shaped thickness sleepers to make the top surface elevation the same, and the sleeper surface of the traversing track is level. When the traversing track is placed on the cover beam with a large cross slope, the low side of the cover beam needs to be stacked with a high sleeper pier. Due to the poor integrity and stability of the sleeper pier, the large-height pier is even worse. When erecting beams, sleeper buttresses are prone to damage and collapse due to insufficient supporting strength or poor stability, and scattered buttresses, which will lead to collapse accidents of bridge erecting machines. There are no cases nationwide. On the other hand, the use of sleeper buttresses as the support structure for the front traversing track of the bridge erecting machine has a non-standard structure, and there are great human factors and hidden dangers in the stacking quality of the sleepers, and the stacking speed is slow. When one span of the bridge is installed and the next span is installed, it is necessary to dismantle the cross-ties buttresses and transport them to the next cap beam for re-stacking and stacking, which takes a long time. To sum up, the traditional method of using sleeper buttresses to support the front traversing track of the bridge erecting machine has poor safety, low work efficiency, and backward methods.

In the prior art, it is difficult to standardize the sleeper buttresses, and there are defects such as irregular stacking, insufficient safety, low degree of mechanization, slow work progress, and high construction costs. The invention innovates and improves the shortcomings of the prior art, and solves the defects existing in the prior art.

Construction principle and method of the present invention:

1. In order to realize that the present invention can be used repeatedly, the rubber bearing and the reverse buckle steel plate are connected by bolts, and the rest of the parts are connected by welding. When welding is used, it should be ensured that the strength of the joint meets the construction safety requirements and does not break during the construction process ( cracking), especially the combined steel structure of the supporting beam and the front traversing track of the bridge erecting machine must be firmly welded. The bottom end of the adjusting screw is equipped with a convex arc-shaped steel ball head, which forms a spherical hinge support with the concave arc-shaped steel structure below it. When the horizontal slope is high, ensure that the contact surface between the adjusting screw and the concave arc steel structure below is always in close contact, without creating gaps and local concentrated stress, preventing super-strength damage of the structure, and playing a good role in transmitting vertical loads. In addition, by setting an arc crater with a certain depth in the steel structure of the concave arc surface below, the steel ball head of the convex arc surface can always be in the pit under different conditions of the cross slope of the cover beam, and the convex arc surface can be reliably prevented. The steel ball head slides out of the pit to cause damage.

5. The bridge erecting machine moves laterally to hoist the remaining concrete precast beams at the same span.

6. Install the cable-stayed lanyard between the screw rod and the upper ring of the concave arc-shaped steel structure and tighten it, so that the adjustment screw part is fixedly connected with the base part and forms a whole.

7. Repeat steps 4, 5 and 6 to complete the erection of the prefabricated concrete beams on the entire bridge.

8. After the concrete prefabricated beam is erected, untie the cable-stayed lanyard, remove the base part, unscrew the adjusting screw part, remove the front traverse track part from the front leg of the bridge erecting machine, and classify and transport it to the next bridge erecting machine. 1.
