A device for removing Bailey beams and its construction method

Abstract

The invention discloses a device for removing a Bailey beam, which comprises a beam frame and a bottom plate. The right side of the upper surface of the beam frame is fixedly connected with a driving mechanism for providing power, and the middle part of the upper surface of the beam frame is rotatably connected. There are a plurality of shaft sleeves, and a transmission mechanism that cooperates with the driving mechanism is arranged in the plurality of shaft sleeves, and a limit mechanism for clamping the bottom plate is provided at the lower end of the bottom plate. The present invention also proposes a construction method for dismantling the Bailey beam, comprising the following steps: S1, installation; S2, fixing; S3, activating the overall lowering system; S4, dismantling; S5, recycling. The invention has a reasonable structure and ingenious design. The Bailey beam that needs to be dismantled can be hoisted first, and disassembled in a way of first lowering and then upper dismantling, thereby avoiding long-term operation in a high altitude and narrow space, and greatly improving construction safety. .

Description

technical field [0001] The invention relates to the technical field of Bailey beams, in particular to a device for removing Bailey beams and a construction method thereof. Background technique [0002] Bailey beam is a truss beam assembled with Bailey frame, and Bailey frame, which is a steel frame that has formed a certain unit, can be spliced ​​and assembled into many components and equipment. The length and width of the Bailey frame are generally 3m×1.5m, and the opening window is usually used as the connecting member between the Bailey frames, which are fixed with bolts. Because of its rapid erection and strong mobility, it is often used to erect simple bridges on rivers and cliffs during wartime, and is now mostly used in engineering construction, such as gantry cranes, construction platforms, engineering access bridges, etc. Bailey beam erection is convenient and quick, and it provides a prerequisite for the support in many continuous cast-in-place beams across highwa...

AI Technical Summary

Problems solved by technology

In the construction of hanging baskets and highways crossing the river, it can also provide access roads for the construction to increase the speed and convenience of the construction. However, after the construction is completed, the previously erected Bailey beams must be dismantled, but the existing ones are used for demolition. There are some problems in the Bailey beam device, such as; 1. The existing construction idea for dismantling the Bailey beam device is "remove layer by layer from top to bottom". And it needs to work in a small space at high altitude for a long time, and there are major safety hazards;

[0003] 2. Existing devices for dismantling Bailey beams take a lot of time to dismantle Bailey beams, resulting in a longer construction period, greater investment in operators and materials, and higher construction costs
