Combined component for railway construction

Abstract

The invention discloses a combined component for railway construction. The combined component comprises a bottom plate, a supporting mechanism is connected to the top end of the bottom plate in a clamped mode, a fixing mechanism is movably connected to the inner side of the supporting mechanism in an inserted mode, and a buffering mechanism is connected to the top end of the supporting mechanism in a threaded mode. The invention relates to the field of railway construction. Connection and fixation of the supporting mechanism are achieved through the fixing mechanism, the supporting mechanism is responsible for supporting the buffering mechanism, the fixing mechanism is only responsible for connection and fixation of the supporting mechanism, it is not needed to pour a large amount of concrete, the dead weight of the structure of the device is increased, the concrete pouring amount used by the fixing mechanism is reduced, through a first connecting rod, a second connecting rod, a connecting bolt, a limiting frame, a limiting pressing plate and a limiting bolt, the anti-torsion and anti-deformation capacity of the combined component is improved, and meanwhile the structural dead weight of the combined component is reduced. The problems that an existing combined component structure for railway construction is large in weight, high in maintenance and use cost and inconvenient to carry are solved.

Description

technical field [0001] The invention relates to the field of railway construction, in particular to a combined component for railway construction. Background technique [0002] From railway construction design to civil, mechanical, signal and environmental engineering fields, sleepers are the most used and most important combined component in the railway construction process. [0003] The existing patent (notification number: CN101851879B) discloses a composite sleeper, which includes a sleeper main body and elastic strips. There are pre-embedded iron seats on both sides, and there are under-rail rubber pads between the pre-embedded iron seats. The upper surface of the under-rail rubber pads is provided with tracks, and the upper surfaces on both sides of the bottom of the rails are provided with rails. One end of the elastic bar is inserted into the through hole of the pre-embedded iron seat, and the other end is pressed on the upper surface of the gauge block. The inside ...

[0003] The existing patent (notification number: CN101851879B) discloses a composite sleeper, which includes a sleeper main body and elastic strips. There are pre-embedded iron seats on both sides, and there are under-rail rubber pads between the pre-embedded iron seats. The upper surface of the under-rail rubber pads is provided with tracks, and the upper surfaces on both sides of the bottom of the rails are provided with rails. One end of the elastic bar is inserted into the through hole of the pre-embedded iron seat, and the other end is pressed on the upper surface of the gauge block. The inside of the main body of the sleeper is provided with a number of prestressed steel wires, and the prestressed steel wires Through the fixed connection of stirrups, the inside of the sleeper cap is equipped with reinforcing steel mesh, and the sleeper device obtains high compressive strength, oblique section shear strength, crack resistance and strong deformation resistance, greatly The bearing capacity and service life of the sleeper device are improved, and a large amount of wood can be saved at the same time. In other existing patented technologies CN212560958U, a U-shaped frame is arranged between two base templates, and the concrete pouring of the base templates with different spacings is realized with the adjustment screw , but the U-shaped frame is an integral structure, which is inconvenient for disassembly and maintenance after partial damage. In CN103243621A, an integrated horizontal plate structure is adopted between the two bottom plates, but a separate support needs to be provided for the deformation of the horizontal plate Floor

In the process of realizing the present invention, the inventors found that at least the following problems in the prior art have not been solved: 1. While the device guarantees its own high compressive strength, its own structure has a relatively large dead weight and consumes a lot of production materials ; 2. The device is damaged during use, and the entire sleeper needs to be replaced, and the cost of maintenance and use is relatively high; 3. The device is inconvenient to take during installation and transportation, and it is inconvenient for maintenance personnel to operate the device when moving it
