Problems solved by technology

762mm gauge turnouts are mostly built in tunnels, with limited available space, low operating speed, and often large axle loads, which are fundamentally different from 1435mm standard gauge. Existing standard gauge turnouts and their related designs cannot be applied to 762mm Gauge switch
Based on practical application, the design of 762mm gauge turnout is relatively difficult, and there are few 762mm gauge turnouts in China

Embodiment Construction

[0037] In order to better understand the purpose, structure and function of the present invention, below in conjunction with accompanying drawing, the present invention is suitable for 762mm gauge No. 3.5 symmetrical turnouts and its construction method to be described in further detail.

[0038] Such as Figure 1-8 As shown, it is shown as the No. 3.5 symmetrical turnout suitable for 762mm gauge of the embodiment of the present invention, more specifically a kind of No. 3.5 symmetrical turnout suitable for 762mm gauge P50 (50kg / m) rail. The overall length a of the symmetrical turnout is 7720-7724mm, and the front length a 1 It is 3551~3555mm, and the back length is a 2 It is 4167 ~ 4171mm. Preferably, the full length a of the symmetrical turnout is 7722mm, and the front length a 1 3553mm, back length a 2 It is 4169mm. The size of the entire symmetrical turnout is small, and the occupied space is small, which can adapt to working conditions with limited space such as tunn...

Abstract

The invention provides a No. 3.5 symmetrical turnout suitable for a 762 mm gauge and a construction method thereof. The symmetrical turnout is 7720-7724 mm in overall length a, 3551-3555 mm in front length a1 and 4167-4171 mm in rear length a2 and is composed of a switch part, a frog and a guard rail part, wherein the switch part comprises two stock rails, two switch rails and two switch guide rails, the switch rails are connected with the switch guide rails, the switch rails and the switch guide rails are both located between the two stock rails, the two switch rails are of curved structures,and the ends of the two switch rails can be alternately attached to the stock rails on the same side. The 762 mm gauge type symmetrical turnout is provided and can realize stable track changing of atrain and ensure the safety of the train.

Description

technical field [0001] The invention relates to the field of railways, in particular to a No. 3.5 symmetrical turnout with a gauge of 762 mm and a construction method thereof. Background technique [0002] At present, domestic railways and urban rail transit turnouts are mostly 1435mm standard gauge. There are few railways with a gauge of 762mm, and they are only used in a small number of tourist trains. However, with the vigorous development of military-civilian integration projects in the domestic market, the application of 762mm gauge switches is becoming more and more extensive. 762mm gauge turnouts are mostly built in tunnels, with limited available space, low operating speed, and often large axle loads, which are fundamentally different from 1435mm standard gauge. Existing standard gauge turnouts and their related designs cannot be applied to 762mm Gauge switch. Based on practical application, the design of 762mm gauge turnout is relatively difficult, and there are f...
