Embodiment Construction

[0026] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the described embodiments are some, not all, embodiments of the present invention. The specific embodiments described here are only used to explain the present invention, but not to limit the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention belong to the protection scope of the present invention.

[0027] Such as figure 1 As shown, the guide beam is erected on the existing railway line. The guide beam has the middle part of the guide beam arm 601 along the direction of railway travel and the transverse pad beam 602 along the direction of the bridge pier. The middle part of the guide beam arm 601 and the transverse pad beam 60...

Abstract

The invention relates to girder replacement construction equipment for a bridge, in particular to a gantry crane bracket with a lifting function. The gantry crane bracket includes a base part and a support part which is arranged on the upper part of the base part and used for erecting a gantry crane, the base part is provided with a connection part for lifting the support part, the lifting heightof the support part is fixed by a limiting part, and a travelling part is arranged at the lower end of the base part. According to the gantry crane bracket, the support part of the gantry crane bracket has the lifting function, in the process of supporting the gantry crane, the support part is located at a low position, thus the problem of exceeding a railway height limit is effectively prevented,when it is necessary to lower the gantry crane to a guide beam, the support part is located at a high position, and thus lowering of the gantry crane is facilitated.

Description

technical field [0001] The invention relates to bridge beam replacement construction equipment, in particular to a gantry crane bracket with a lifting function. Background technique [0002] Due to the long design time and long operation time, there are a large number of sick service girder bridges in the existing railway bridges. On the existing line, the bridge replacement operation can be implemented by adjusting the train operation diagram or the train operation gap and using the gantry crane or the lateral movement of the bracket. This operation mode has the advantages of no need to build a convenient line, less cost, no environmental pollution, and a shorter construction period. advantage. [0003] When the gantry crane is in construction, a guide beam will be set at the beam to be replaced on the railway, and the gantry crane can be supported by the guide beam, so that the gantry crane can remove the old beam and install the new beam. [0004] The gantry crane is su...
