TECHNICAL FIELD

[0001] The present application belongs to the technical field of track slab production, and particularly relates to a track slab production system and method. BACKGROUND

[0002] The track slab refers to a new type of track component in a plate body structure type, used to support and fix the steel rail, and distribute the load transmitted by the steel rail to the base under the plate.

[0003] In the prior art, the production of the track slab is achieved by connecting the steel bars to form a steel mesh, pouring the concrete on the steel mesh, and waiting for the concrete to solidify. However, this method can only produce one type of track slab at a time, and when the type of the track slab to be produced needs to be changed, the production line needs to be emptied and re-injected, which is extremely low in production efficiency. SUMMARY

[0010] A steel bar transportation mechanism, the steel bar transportation mechanism being used to transport the bound steel mesh to the steel mesh storage area.

[0011] In the technical scheme, the same steel bar production line can produce different types of steel mesh, and the steel mesh is transported to the corresponding steel mesh storage area in the track plate production line. The steel mesh is moved to the corresponding concrete pouring area, and the concrete is transported to the corresponding concrete pouring area by the concrete transportation mechanism to form the track plate. It can utilize one steel bar production line and one concrete production line to supply multiple track plate production lines, and multiple track plate production lines can produce simultaneously to improve production efficiency.

[0012] In some embodiments, the concrete transportation mechanism includes a concrete transportation channel, a first track arranged in the concrete transportation channel, and a transportation hopper slidably connected to the first track. The concrete pouring areas in all the track production lines are close to the concrete transportation channel.

[0013] In the technical scheme, when pouring concrete, the transportation hopper is moved to the mixing station through the first track, the concrete output by the mixing station enters the transportation hopper, and the transportation hopper moves on the first track to the corresponding track plate production line. The transportation is convenient and fast, and the efficiency is improved.

Multiple track plate production lines are arranged on both sides of the concrete transportation channel, and the production direction of each track plate is away from the concrete transportation channel.

[0015] In the technical scheme, the layout is reasonable and convenient for concrete transportation. Moreover, the produced track plate in the curing area is close to the edge of the factory building, which facilitates the transportation of the produced track plate.

[0016] In some embodiments, the steel bar transportation mechanism includes a steel bar transportation channel, a second track, and a transportation vehicle. The steel bar transportation mechanism includes two groups and is arranged on both sides of the concrete transportation channel. The steel bar transportation channel passes through between the concrete pouring area and the steel mesh storage area in the track plate production line. The second track is arranged in the steel bar transportation track, and the transportation vehicle is slidably connected to the second track.

[0017] In the technical scheme, multiple track plate production lines located on both sides of the concrete transportation channel can transport steel bars through the transportation vehicle in the corresponding transportation channel.

[0023] The application further provides a track slab production method, which applies the track slab production system as described above, and the specific steps are as follows:

[0024] Steel mesh manufacturing: moving the steel bars in the steel bar storage area to the steel bar processing area for shearing and bending, and moving the processed steel bars to the steel bar binding area to form a steel mesh by binding;

[0025] Concrete pouring: moving the steel mesh to the mold by using the hoisting device; outputting the concrete output by the mixing station to the transport hopper, lifting the transport hopper by using the hoisting device and moving the transport hopper above the mold in which the steel mesh has been placed, opening the hopper to pour the concrete into the mold;

[0028] In the technical scheme, the rail plate production lines are of different types, so that the multiple rail plate production lines can produce rail plates of different types at the same time. Moreover, the steel bar production line and the concrete production line can simultaneously meet the requirements of the multiple rail plate production lines, thereby maximizing cost saving and improving efficiency.

[0029] In some embodiments, after the pouring of the concrete, the water curing is preceded by a step of steam curing, which is: covering the mold with a tarpaulin, waiting for 18 hours, then removing the tarpaulin and the mold; at this time, the concrete in the mold is solidified to form the rail plate.

[0030] In the technical scheme, the mold is covered with the tarpaulin, steam is generated in the tarpaulin, and the rail plate being formed is cured, so that a reasonable humidity range is provided, and subsequent cracking of the rail plate is avoided.

[0031] In some embodiments, after the tensioning of the rail plate, the step further includes a step of rail plate curing, which is: using hoisting equipment to hoist and move the rail plate to a curing area.

[0032] In the technical scheme, the rail plate is placed in the curing area for curing, so that problems such as cracking of the rail plate caused by large temperature changes of the outside weather are avoided, and the quality of the rail plate is improved.

[0083] In an embodiment, the specific steps of tightening the nuts at both ends of the prestressed steel bar, abutting the nuts against both sides of the track slab, and continuing to tighten the nuts to stretch the prestressed steel bar in step S600 of track slab tensioning are as follows: tightening the nuts by the tensioning device. The tensioning force can be accurately controlled.

[0084] In an embodiment, the steps after tightening the nuts by the tensioning device in step S600 of track slab tensioning are as follows: mixing the anchoring mortar, and filling the anchoring holes with the anchoring mortar.

[0085] In an embodiment, the steps after step S600 of track slab tensioning further include step S700 of track slab curing, which is as follows: lifting the track slab by the lifting device and moving to the curing area 205. The track slab is placed in the curing area 205 for curing, which avoids large temperature changes in the outside weather from causing the track slab to crack and improves the quality of the track slab.

[0086] After step S700 of track slab curing, step S800 of track slab storage is further included, which is as follows: after the track slab is stored in the curing area 205 for 24 days, the track slab is transported to the outdoor storage area 800 for storage.

[0087] Finally, it should be noted that: the embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts of each embodiment can be referred to each other.

[0088] The above examples are only used to illustrate the technical solutions of the present application but not to limit the present application; although the present application has been described in detail with reference to the preferred embodiments, it is understood by the person of ordinary skill in the art that the specific embodiments of the present application can be modified or some technical features can be replaced by equivalent ones without departing from the spirit of the technical solutions of the present application, and all of them should be covered in the technical solution range of the present application claimed.
