Description

Technical Field

[0001] The invention relates to the technical field of production of steel rail turnouts and crossover prefabricated plates, in particular to a forming mould for steel rail turnouts and crossover prefabricated plates. Background Art

[0002] Rail turnouts are used for track switching, while precast crossover slabs are prefabricated panels used to support crossover structures. Both are used in railway construction and maintenance. Turnouts are the connecting devices that allow rolling stock to transfer from one track to another. They are also one of the weak links in track, and are typically installed in large numbers at stations and marshaling yards. Turnouts maximize the capacity of a line. Even on single-track railways, laying turnouts and constructing a crossover track longer than the length of the train allows trains to run in opposite directions.

[0003] Precast slabs for rail switches and crossovers are used in railway construction and maintenance. During the production of the precast slabs, molds need to be used for casting and forming. However, the rail switches and crossovers are complex and changeable. The size and size of each slab are different, and the nail hole distance position is also different. Each slab must be invested in a set of steel molds. The number of molds is large, the cost is high, and the mold investment cost is high. In addition, when the precast slabs are formed, a vibrator is needed to shape the concrete to eliminate bubbles. However, during the vibration process, the vibration direction and speed of each part are different, and the concrete cannot be vibrated quickly. It is easy to cause incomplete vibration, thereby forming voids or honeycombed surfaces, resulting in internal damage to the product. In addition, the efficiency of manual vibration is low. Based on this, a forming mold for precast slabs for rail switches and crossovers is proposed. Summary of the Invention

The transmission shaft 1310 drives different transmission shafts 1310 to rotate through the transmission sprocket 1311 and the transmission chain 1312, and the rotating motor 1314 And the bearing support 1313 is passed, and the bolts are fixed to the mounting platform. When the transmission shaft 1310 rotates, it drives the transmission plate 1308 through the leather soft connection 1309, and then drives the rotating rod 1305 to rotate. The rotating rod 1305 rotates with the support of the support bearing 1316, and the rotating rod 1305 drives the eccentric wheel 1306 to rotate, so that the eccentric extrusion of the eccentric wheel 1306 contacts the rolling ball 1408, thereby pushing the connecting column 1407 up and down through the eccentric action, and then the connecting column 1407 drives the hammer movable plug 1406 to move up, and The elastic force of the return spring 1405 causes the rolling ball 1408 to maintain a relative position with the eccentric wheel 1306, and strikes the bottom vibration plate 14 by the upward movement of the hammer movable plug 1406, and then transmits the vibration effect to the bottom of the bottom mold 4 through the support column 1404. The bottom mold 4, under the connection of the rubber buffer column plate position 8 and the mounting seat 1301, elastically stabilizes the vibration force through the support column 1302 and the shock absorber 1303. The corresponding linear uniformity of the eccentric wheel 1306 and the vibrating sleeve 1401 makes the vibration effect uniform, which is convenient for The concrete inside the bottom mold 4 is vibrated to ensure the uniformity of the concrete, reduce bubbles and ensure the quality of the concrete, and the rolling ball 1408 can be replaced by a transversely rotating bearing with the same width as the eccentric wheel 1306. The bearing is supported by the mounting groove inside the connecting column 1407 and the fixed shaft in the middle, and is used to make rolling contact with the outer side of the eccentric wheel 1306. When the eccentric wheel 1306 rotates to the maximum position, the rolling force is changed into a vertical limiting effect, which is convenient for vibrating the bottom of the bottom mold 4, thereby indirectly promoting the uniformity of the vibration.
