Description

Technical Field

[0001] The utility model relates to the technical field of subgrade leg mechanisms, specifically a subgrade leg mechanism. Background Technique

[0002] During the production process of bridges, it is necessary to select a suitable crane according to the bridge height, remove the lower guide beam legs of the bridge erecting machine and transfer them to the next pier to be erected for installation. However, the existing subgrade leg mechanisms still have certain defects when in use.

[0003] During the use process, the existing subgrade legs are at the rear end of the bridge erecting machine. The rear traveling crane is locked with the subgrade legs, and the main truss is driven forward by the rear traveling crane. Then the middle subgrade legs are locked, and the bridge erecting machine and the beam are moved to the next span together, and the abutment leg position is reached in turn. The overall operation takes a long time, resulting in low overall operation efficiency.

[0004] In order to overcome the above defects, the prior art 1 (a Chinese patent with the application number 202221970451.4 and the application date of July 28, 2022) is a subgrade device for a bridge erecting machine. By setting a pulley block, when the bridge erecting machine crosses the subgrade or continuous beam, start the electric chain hoist, and use the hinge connecting the leg and the lower guide beam of the bridge erecting machine to fold the leg 90 degrees to fit with the lower guide beam of the bridge erecting machine. When the lower guide beam of the bridge erecting machine has crossed the subgrade or continuous beam, start the electric chain hoist to open the leg and restore it to the state to be erected. During the process, there is no need to use a crane, which takes less time, is safe and controllable, improves the construction efficiency of the bridge erecting machine, and reduces the labor intensity of the operators.

[0005] Although the prior art can improve the operation efficiency, during the working process, by opening and closing the legs, the overall operation is inconvenient, and the whole needs to cooperate with the hoisting structure and use the longitudinal movement mechanism for transverse movement. However, due to the limitation of the actual beam hoisting environment, the whole needs to be leveled multiple times to pass through the hole, which increases the labor intensity of the operators, reduces the overall construction safety, and reduces the overall operation efficiency.

[0006] In view of the above problems, it is urgent to innovate and design on the basis of the original subgrade leg mechanism. Therefore, we have proposed a subgrade leg mechanism that can well solve the above problems. Content of the Utility Model

[0007] The purpose of the utility model is to provide a subgrade leg mechanism to solve the problems in the above background technique, that is, in the current market, by opening and closing the legs, the overall operation is inconvenient, and the whole needs to cooperate with the hoisting structure and use the longitudinal movement mechanism for transverse movement. However, due to the limitation of the actual beam hoisting environment, the whole needs to be leveled multiple times to pass through the hole, which increases the labor intensity of the operators, reduces the overall construction safety, and reduces the overall operation efficiency.
