Section assembling method of portable bridge deck crane for railroad bridge
The invention discloses a section assembling method of a portable bridge deck crane for a railroad bridge. The section assembling method comprises the following steps that a 0 # section is installed and anchored; mounting a single bridge fabrication machine; the first section is transported and assembled; the other bridge fabrication machine is installed, and the two bridge fabrication machines are connected end to end; the second segment is transported and lifted; a second section is spliced through a suspended splicing method; the bridge fabrication machine passes through the hole and is provided with a bridge deck beam transporting vehicle; the third section is lifted; a third section is spliced through a suspended splicing method; the other sections are repeatedly assembled; side span transition sections are installed; erecting a segmental beam of the T-shaped structure; and dismantling the equipment to complete the full-bridge construction. According to the construction method, the problem that when a bridge deck crane cannot feed the beam under the bridge for hoisting, the beam is fed from the tail on the bridge is solved. According to the construction method, the segments do not need to rotate by 90 degrees, and large bending moment cannot be generated on the bridge. The bridge deck crane solves the problems that a traditional bridge deck crane needs to enable a segment to stretch out for a long distance to rotate, so that the upward pulling force of an anchor bolt of the crane is too large, and the unbalanced bending moment of a pier top is too large.
本发明公开了一种铁路桥梁轻便式桥面吊机的节段拼装方法，包括以下步骤：安装并锚固0#节段；安装单台造桥机；运输并拼装1#节段；安装另一台造桥机，并将两台造桥机首尾相连；运输并提升2#节段；采用悬拼法拼装2#节段；造桥机过孔并安装桥面运梁车；提升3#节段；采用悬拼法拼装3#节段；重复拼装其余节段；安装边跨过渡节段；架设T构的节段梁；拆除设备，完成全桥施工。本发明的施工方法解决桥面吊机不能桥下喂梁起吊时，从桥上尾部喂梁的问题。本发明的施工方法中节段无需旋转90°，不会对桥梁产生较大弯矩。本发明解决了传统桥面吊机需要把节段伸出较远距离旋转而造成吊机锚栓上拔力过大、墩顶不平衡弯矩过大的问题。
