Problems solved by technology

[0006] The purpose of the present invention is to overcome the existing track slab molds in the prior art that each track slab needs to be clamped and removed separately before and after production, so that the accuracy and flatness of each track slab produced by it are consistent. It is difficult to guarantee the performance requirements, and the above-mentioned shortcomings of low production efficiency and large demand for human resources provide a kind of production tooling equipment and method of the pre-tensioned track slab assembly line method. The device for tensioning and releasing the track plate adapted to the mold

Embodiment 1

[0093] Such as Figure 1-10Shown, the pre-tensioned track slab assembly line method production tooling equipment of the present invention comprises:

[0094] The track slab mold 1 includes a bottom mold 12 and side molds 11 connected around the bottom mold 12, used to set a ballastless track slab structure including a reinforcement cage and a prestressed steel bar 6, and cast the mold in it. track plate;

[0095] The tension rod 2 is arranged at the four side molds 11 of the track slab mold 1, and is used for screwing the prestressed steel bars 6 inside the track slab mold 1, and extends to the outside through the side molds. , adapting to the stretching and releasing of the prestressed steel bars 6;

[0096] The tensioning device 3 is adapted to the tension rod 2 and is used for prestressing the prestressed steel bar 6;

[0097] pouring device, for pouring concrete into the track slab mold 1;

[0098] A vibrating device for vibrating the concrete in the poured track slab ...

Embodiment 2

[0113] Such as Figure 1-11 As shown, the production method of the pre-tensioned track slab assembly line method of the present invention uses the pre-tensioned track slab assembly line method to produce tooling equipment as described in Example 1, and the method comprises the following steps:

[0114] A. Clean up the track slab mold 1 on the track transport device 1, and place embedded parts, reinforcement cages and some prestressed steel bars 6 therein;

[0115] B, all described prestressed reinforcing bars 6 are threaded with corresponding tension rods 2;

[0116] C. The track slab mold 1 is adapted to the tensioning device 3 located on the rail transport device 1, and the tensioning device 3 stretches the prestressed steel bars 6 in place, and anchors the tensioning rod 2;

[0117] D, the insulation testing device that is positioned on described rail transportation device 1 carries out insulation test to described reinforcement cage and all described prestressed steel bar...

Abstract

The invention discloses a pre-tensioned track board assembly-unit production tooling device and method. The tooling device comprises a track board mould, tensioning rods, tensioning devices, a pouring device, a rapping device, a steam curing device, relieving devices and demoulding devices. By adoption of the pre-tensioned track board assembly-unit production tooling device, the mould capable of being used repeatedly and apparatus which is used for tensioning, relieving and demoulding a track board and adapts to the mould are adopted for production of the track board, the track board can be jacked up from the bottom of the mould, the mould is separated from the track board, and the purpose that the mould is fixed and not detached in use is achieved. Compared with an existing technical concept, the tooling device is advanced, the mechanization degree is high, manpower demand amount in the track board production process is decreased, and the track board production efficiency is improved; and due to the fact that the used mould does not need to be separately closed or detached before and after each track board is produced, the uniformity of produced track boards by means of the mould is good.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to a production tooling equipment and method for a pre-tensioned rail slab assembly line method. Background technique [0002] With the rise of high-speed railways, in order to ensure the high-speed operation of trains on the rails, ballastless track slabs have appeared to replace traditional railway sleeper systems. According to the structure of existing ballastless track slabs and the extremely high precision and Flatness requirements, the existing ballastless track slabs in the production process, the use of preset molds, prefabrication of the mold before the track slab molds, prefabricated and then demoulding method. which is, [0003] When using molds to make ballastless track slabs, it is necessary to close each mold to form the cavity shape of ballastless track slabs, and then adjust the molds precisely to meet the shape, size, surface parameters, internal reinfo...
