Embodiment Construction

[0031] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0032] Such as Figure 1-4 As shown, the present invention provides a kind of suspended train track beam, comprises upper cover plate 4, lower cover plate 1, web 3 and rib plate 9, as figure 1 As shown, the bottom of the lower cover 1 is provided with a limit stop 5 for adjusting the camber of the lower cover 1, and the camber curve of the track beam is guaranteed by the height of the limit stop; as figure 2 As shown, a number of detachable process partitions 2 are installed along the length direction of the lower cover plate 1, including a plate body 23. In order to reduce its own weight, the plate body 23 is a back-shaped structure. Such as image 3 As shown, one side of the process partition 2 is provided with a first adjustment screw 21 for adjusting the web 3, and the top of the process partition 2 is provided with a second adjustment screw 22 for adjusting t...

Abstract

The invention discloses a suspension type train track beam, a manufacturing method thereof and technical partition plates for the track beam. The track beam is composed of an upper cover plate, a lower cover plate, webs and rib plates. Limiting stop dogs are arranged between the bottom of the lower cover plate and a platform, and the camber curve of the track beam is ensured by the height of the limiting stop dogs. The technical partition plates are arranged in the length direction of the lower cover plate. A first adjusting screw is arranged on one side of each technical partition plate, and a second adjusting screw is arranged on the top of each technical partition plate. The webs are installed on the two sides of the technical partition plates. The bottom edges of the webs are fixedly welded to the lower cover plate. The upper cover plate is fixedly welded to the tops of the webs. The rib plates are welded outside the webs and the upper cover plate. When the upper cover plate, the lower cover plate and the webs perform discharging, dimensional allowance is reserved in the length direction, the track beam is marked in the length direction after welding so that the allowance can be cut off, and the length dimension of the track beam is ensured; and a tank opening fixing device is arranged, the track beam forms a closed structure in the assembly welding and transportation processes, deformation of a non-closed tank type track beam is effectively controlled, and the dimension precision of the track beam is ensured.

Description

technical field [0001] The invention relates to the technical field of train track technology, in particular to a suspended train track beam, a manufacturing method thereof and a process partition for the track beam. Background technique [0002] In the suspended train rail transit project, the track beam is the basic unit of the suspended train line. It has the functions of supporting the vehicle, bearing its own gravity, guiding force and traction force. Usually there are straddle track beams and closed track beams. , and non-enclosed track beams. [0003] In the existing elevated rail transit, the vehicle runs on the track beam in a straddle type, and the vehicle operation is restricted in rainy and snowy weather. In the suspended train rail transit, the vehicles run inside the track beam without being affected by rain and snow. Among them, the track beam is a closed box structure, which is composed of an upper cover plate, a lower cover plate, a web and a partition, whi...
