[0002] The longitudinal reinforcement of the box girder is the main longitudinal force-bearing structure of the bridge. The transportation of the longitudinal reinforcement is an important process of the railway bridge binding. The traditional way is to use manual transportation. In the traditional factory layout, the storage area of ​​the finished product is far away from the binding area of ​​the steel cage, and its length is often as long as 30m. Therefore, it is necessary to transport it by a team of more than 10 people at the same time. The labor intensity is relatively high, and due to the rust problem of the steel bars themselves, there are certain health hazards to the workers. Because it is a manual operation, the workers often have certain deviations in the transportation of materials, which may lead to insufficient or excessive materials during binding.

DETAILED DESCRIPTION

[0013] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention. The components of the embodiments of the present invention generally described and shown in the accompanying drawings herein can be arranged and designed in a variety of different configurations.

[0014] In the present utility model, unless otherwise clearly stipulated and limited, the terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal connection of two elements.

[0015] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0016] like Figure 1 and Figure 2 As shown, a long longitudinal reinforcement loading and unloading device for a steel cage of a railway bridge in this embodiment comprises a discharging tray 1, a steel bar straightening and cutting device 2, a longitudinal guide transmission device 3 and a longitudinal reinforcement transverse transport device 4 arranged in sequence; a traveling crane 5 is arranged above the longitudinal reinforcement transverse transport device 4, and a handling mechanical arm 6 is arranged on the traveling crane 5; the longitudinal guide transmission device 3 comprises a plurality of coaxially arranged guide slots 31, and rollers 32 for reducing friction are arranged between the guide slots 31.
