Adjustable turnout hook lock

Abstract

The invention relates to the field of railway turnout switching devices, in particular to an adjustable turnout separation type hooking lock setting. According to the adjustable turnout separation type hooking lock setting, the structure is simple, a movable head can extend into an adjusting base, and the opening adjusting range is expanded. The adjustable turnout separation type hooking lock setting comprises the adjusting base, the movable head, an adjusting screw, an adjusting nut and a buckle plate. A through hole is formed in the adjusting base and transversely penetrates through the adjusting base. The movable head is arranged in the through hole of the adjusting base. The adjusting screw extends into the through hole of the adjusting base and is connected with the movable head. The portion, located outside the adjusting base, of the adjusting screw is sleeved with the buckle plate. The adjusting nut is arranged on the portion, outside the buckle plate, of the adjusting screw in a matched mode. According to the adjustable turnout separation type hooking lock setting, the structure is simple, the relative positions between the movable head and the adjusting base are adjusted through the adjusting screw, and therefore separation and locking of the opening can be achieved; meanwhile, the opening locking range is wide, the locking stability is high, and the safety of the position of a separation switch rail is guaranteed when a turnout is out of service or ineffective.

Description

technical field [0001] The invention relates to the field of railway turnout conversion devices, in particular to an adjustable turnout repelling hook locker. Background technique [0002] In the current industry, when the railway switch conversion device fails or is out of service, the position of the switch point rail is mechanically fixed using a switch hook lock to ensure that the point rail does not shift or change when the train passes. The turnout hook locker is divided into a locking hook locker and a repelling hook locker. The existing turnout repelling hook locker can repel and lock the first pulling point of the turnout with an opening of 160mm and the second pulling point of 130mm, but when the opening of the turnout is less than 130mm, the opening of the third pulling point is 80mm, When the six traction points are 20 mm, the repelling and locking cannot be performed, and the position safety of the repelling point rail cannot be guaranteed when the turnout is ...
