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

Example Embodiment

[0092] Example 1

[0093] Such as Figure 1-10 As shown, the pre-tensioned track plate flow unit method production tooling equipment of the present invention includes:

[0094] The track slab mold 1, including a bottom mold 12 and a side mold 11 connected around the bottom mold 12, is used to set up a ballastless track slab structure including steel cages and prestressed steel bars 6, and cast in it. Track board

[0095] Tension rods 2 are provided at the four side molds 11 of the rail slab mold 1 for screwing the prestressed steel bars 6 inside the rail slab mold 1 and extend through the side molds to the outside , Adapt to the tensioning and unwinding of the prestressed steel bar 6;

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

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

[0098] Vibration device for vibrating and forming the concrete in the track slab mold 1 after pouring;

[0099] Stea...

Example Embodiment

[0112] Example 2

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

[0114] A. Clean the track slab mold 1 located on the track transportation device 1, and place the embedded parts, steel cages and some prestressed steel bars 6 in place;

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...
