Problems solved by technology

A square shape means that the rod extends out of the case, two pieces means that there is a gap between the rods, and a square shape means that it is difficult to seal between the rods and between the main rod and the auxiliary rod, so the sealing of the switch machine case is poor
At the same time, when the indicating rod is stretched out, the two indicating rods are respectively connected by the indicating rod joint with bolts and long holes. This kind

Embodiment Construction

[0036] Such as figure 1 As shown, the electro-hydraulic switch machine uses a sleeve-type indicator rod 41, which includes an outer indicator rod 411 and an inner indicator rod 412 that are nested together. At one end of the indicating rod, a notch is set on the outer indicating rod, so that the end of the inner indicating rod is exposed; a connection structure is provided at the ends of the inner indicating rod and the outer indicating rod at this end.

[0037] The overlapping parts of the outer indicator rod 411 and the inner indicator rod 412 are both circular in cross-section. A sealing ring is provided between the outer indicating rod 411 and the inner indicating rod 412 . A sealing ring is provided on the outer side wall of the circular cross-section where the outer indicating rod corresponds to the case wall of the switch machine case.

[0038] The sealing structure is arranged on the circular section, and the sealing is easier and more reliable.

Abstract

The invention provides a sleeve type indication rod for an electric hydraulic switch machine, which comprises an outer indication rod and an inner indication rod. The outer indication rod and the inner indication rod are sleeved together, the outer indication rod at one end of the indication rod is provided with a notch to allow the end of the inner indication rod to be exposed, and a connecting structure is arranged at the end of the inner indication rod and the end of the outer indication rod at the end of the indication rod. The sleeve type indication rod for the electric hydraulic switch machine is easier to be structurally sealed with a box, strength and rigidity of the indication rod can be improved, and the sleeve type indication rod is more reasonable in structure. In addition, by means of the notch structure of the sleeve type indication rod and a junction bend matched with the notch structure, the indication rod can be locked more reliably to guarantee inserting and withdrawing of the moving junction turn to be more reliable.

Description

technical field [0001] The invention relates to an electrohydraulic switch machine, in particular to a sleeve-type indicating rod for the electrohydraulic switch machine. Background technique [0002] The electro-hydraulic switch machine is a special equipment for centralized control of switching switches in railways, underground railways, and urban rail transit stations. It can convert and lock the point rail or center rail of the switch, and at the same time give the position indication of the corresponding point rail. [0003] After the turnout is converted, the position of the turnout is transmitted to the switch machine by the indicating rod connected to the switch rail or the core rail. Constitutes the conditions given by the switch machine. [0004] The turnout has two different positions. Inside the switch machine, there are two different contact groups. Correspondingly, two indicating rods are used to cooperate with the two contact groups. [0005] The display me...
