The invention discloses a switch machine indication rod and a gap inspection device thereof, and belongs to the technical field of switch machines for railway turnouts. The indication rod comprises anindication rod body and an indication gap formed in the indication rod body. An axial long groove is formed in one side of the indication gap of the indication rod body to install a gap inspection device, the long groove comprises a guide groove and an inverted T-shaped groove which are communicated in the axial direction; the inverted T-shaped groove is close to one side of the indication gap; aside gap communicated with the upper part of the inverted T-shaped groove is formed in the inclined plane which is adjacent to the inverted T-shaped groove and represents the gap; the gap inspectiondevice comprises an inspection block capable of sliding in the inverted-T-shaped groove in a reciprocating mode, the upper portion of the side face of the inspection block is integrally connected withan extending end capable of extending out of the side gap, and the extending end is matched with an inspection column of the switch machine to inspect the close attachment state of the turnout. The inverted-T-shaped groove is formed in the center of the indication rod, no groove is formed under the indication gap, and the tensile strength of the indication gap is improved.
本发明公开了一种转辙机表示杆及其缺口检查装置,属于铁路道岔用转辙机技术领域,所述表示杆包括表示杆本体和设在表示杆本体上的表示缺口,在所述表示杆本体的表示缺口一侧开设有轴向的长槽,用于安装缺口检查装置,所述长槽包括轴向连通的导向槽和倒T型槽,所述倒T型槽靠近表示缺口一侧,与所述倒T型槽相邻的表示缺口的斜面上设有与所述倒T型槽上部连通的侧缺口,所述缺口检查装置包括能在倒T型槽内往复滑动的检查块,所述检查块的侧面上部一体连接有能从侧缺口伸出的伸出端,用于与转辙机的检查柱配合检查道岔密贴状态。本发明通过在表示杆中心位置开倒T型槽的形式,并没有在表示缺口的下方开槽,提高了表示缺口部位的抗拉强度。
