Problems solved by technology

In addition, some high-speed turnouts in Germany have adopted a hydraulic anti-jump structure, that is, after the heart rail is switched and tightly attached, the heart rail is pressed by a rod passing through the heart rail. This anti-jump effect is better than all heart rail anti-jump solutions. However, the cost is relatively high, and it can only be realized by interlocking with electrical equipment. Figure 4

Embodiment 1

[0014] Embodiment 1: with reference to attached figure 1 . The anti-jump device is composed of an anti-jump board 1, an anti-jump support board 3, two right-angle welding blocks 2 and 4, and a bottom plate 5. Zigzag structure, two pieces of right-angled welding blocks 2 and 4 are respectively welded to the right-angled sides in the right-angled Z-shaped structure. The machining of each component of the anti-jump device is easy to realize. After the machining of each component is completed, the overall device is formed by welding. The existing technology and equipment can meet the processing requirements. Stainless steel with different thickness specifications is machined to form the adjustment piece, the process method is simple and easy to realize.

Embodiment 2

[0015] Embodiment 2: with reference to attached figure 1 and 2 . On the basis of Embodiment 1, a new type of heart rail anti-jump system composed of anti-jump devices, the anti-jump device is installed on the anti-jump support plate 6, and the anti-jump support plate 6 is installed on the wing rails 8 on both sides. The gap between the anti-jump plate 7 in the anti-jump device and the anti-jump platform at the front end of the long heart rail is 1 ± 0.5mm between the jump device and the support plate. The thickness of the adjusting sheet 7 can be changed.

[0016] The anti-jump platform design is added to the front end of the actual tip of the long core rail, and the existing technology and equipment can meet the processing requirements.

Abstract

The invention relates to an anti-jumping device which can prevent a long point rail from jumping and a novel point rail anti-jumping system consisting of an anti-jumping device; the anti-jumping device is arranged on an anti-jumping supporting plate; the anti-jumping supporting plate is arranged on wing rails at two sides; through an adjusting sheet arranged between the anti-jumping device and the supporting plate, the clearance between the anti-jumping plate of the anti-jumping device and an anti-jumping platform in the front end of the actual tip of the long point rail is adjusted to between 0.5 and 1.5 millimeters. The anti-jumping device has the advantages that through adjusting the clearance between the anti-jumping plate of the anti-jumping device and the anti-jumping platform in the front end of the actual tip of the long point rail by the adjusting sheet, the anti-jumping function of the anti-jumping device is realized.

Description

technical field [0001] The invention relates to an anti-jump device capable of preventing long heart rail from jumping and a novel heart rail anti-jump system composed of the anti-jump device, which belongs to the field of manufacturing railway turnout devices. Background technique [0002] The anti-jumping function of the center rail of the existing turnout is mainly realized by the anti-jump iron and the anti-jump top iron. The anti-jump iron is connected by bolts and installed on the wing rail. When the heart rail is closed, the anti-jump iron restricts the jump of the heart rail; The anti-jump top iron is also connected with the wing rail by bolts, and the end of the top iron restricts the upward jump of the upper surface of the bottom of the core rail. However, due to the accumulation of manufacturing errors of various components, the actual anti-jump iron and the anti-jump effect of the anti-jump iron are not very good. [0003] The anti-jumping function of the heart ...
