Self-compensating contact heel group for railway

Abstract

The invention discloses a self-compensating contact heel group for a railway. The self-compensating contact heel group comprises a contact heel seat, a contact ring and an eccentric compensation shaft, a clamping ring, a locking nut and a contact ring are sequentially arranged at the upper part of the eccentric compensation shaft from top to bottom, and a hole matched with the clamping ring and the threads matched with the locking nut are formed at the top end of the upper part of the eccentric compensation shaft; the lower part of the eccentric compensation shaft is provided with the internalthreads, a standard fastener matched with the internal threads is arranged in the contact heel seat, and the internal threads are matched with the standard fastener to install the lower portion of the eccentric compensation shaft in the contact heel seat; a flat washer, a spring washer and a bolt are sequentially arranged at the lower portion of the eccentric compensation shaft from top to bottom, and a threaded hole matched with the bolt is formed at the bottom end of the lower portion of the eccentric compensation shaft. The contact heel group is used for controlling the action of a railwayturnout switch machine, indicating that an inbound and outbound turnout stays at a positioning or reverse position and state and realizing the mechanism locking and the electrical interlocking of thecontact heel group, and is particularly suitable for the contact heel groups of the high-speed railways and subways which can be adjusted automatically and are stable in performances.

Description

technical field [0001] The invention relates to the technical field of railway turnout switch machines, in particular to a self-compensating automatic contact group for railways. Background technique [0002] With the development of international trade, logistics and tourism, there is a huge pressure on the railway transportation capacity. In order to adapt to the formation of the high-speed railway network of the national railway passenger dedicated line, especially the rapid development of high-speed railway capacity, it is estimated that the national passenger dispatch in the Spring Festival in 2019 The number of passengers will reach 2.98 billion. According to the data, the ordinary railway Xi’an Railway Station has only 5 platforms and 9 passenger lines, while the high-speed railway station Xi’an North Station has 18 platforms and 34 train lines, but the incoming and outgoing lines are two lines. It is required to set up nearly 10 times the number of power switch machin...

AI Technical Summary

Problems solved by technology

[0004] From the above situation, it can be seen that the original scheme can no longer meet the needs of the running speed of railway passenger cars, and the improved scheme cannot fundamentally solve the problem. There are major problems in this design
