A turnout locking device

Abstract

The invention discloses a turnout locking device, which comprises rails, point rails, driving mechanisms and a locking mechanism. Sleeper plates are mounted on the lower surfaces of the rails and thepoint rails at equal intervals; the point rails are located between the adjacent rails and can be arranged in the mode of making contact with one sides of the rails; the driving mechanisms are fixedlyarranged on the sleeper plates; one ends of driving rods transmit power to the point rails through inserting rods, at the moment, the point rails are driven to get close to the rails till the point rails make contact with one sides of the rails, and the turnout closing purpose is achieved; and when limiting plates arranged on the point rails are inserted in inserting grooves and continue to moveforwards, one ends of the limiting plates finally make contact with one sides of the lower ends of movable plates and drive the sides of the lower ends of the movable plates to move till plug pins inupper supporting blocks on the movable plates penetrate through the movable plates and finally are clamped in the limiting plates, and at the moment, one sides of the point rails make contact with onesides of the rails to achieve the locking purpose so as to prevent the situation of shaking of a locomotive in the process of passing through a turnout.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a switch locking device. Background technique [0002] Railway turnout is an indispensable equipment for railway transportation, and it is a line connection device for rolling stock to transfer from one track to another. The most common common single turnout includes two point rails, two basic rails, switch machines and connecting rods. The switch machine pulls left and right through a connecting rod to change the position of the two point rails and control the opening direction of the turnout. Railway turnouts are divided into automatic turnouts and manual turnouts. Manual turnouts are manually pulled back and forth to achieve path preparation. If the turnout If it is arbitrarily moved by non-operators, the turnout will open to the wrong direction of the line, resulting in traffic accidents. For manual turnouts, people usually use the following two methods to protect them ...

Problems solved by technology

The switch machine pulls left and right through a connecting rod to change the position of the two point rails and control the opening direction of the turnout. The railway turnout is divided into automatic turnout and manual turnout. The manual turnout is manually pulled back and forth to achieve path preparation. If the turnout If it is arbitrarily moved by non-operators, the turnout will open to the wrong direction of the line, resulting in traffic accidents. For manual turnouts, people usually use the following two methods to protect them from driving accidents: The first is to equip a crossing The operator is responsible for turning and checking the turnout, which has high labor cost and high operating efficiency, and is suitable for places with a large amount of work; the second is that the on-board shunting officer is responsible for stopping in front of the turnout, turning and confirming the turnout, It has low labor cost and low operating efficiency, and is suitable for places with a small workload. However, although this method can be used for turnout work, there are great safety hazards. The staff need to work on the railway. Once the danger occurs, the consequences will be unimaginable. , In addition, the staff need to spend a lot of effort when turning the switch. When the turnout is aging, the staff needs to spend more effort to turn it, which has great limitations. For this reason, we provide a turnout locking device , to solve the problems raised in the above background technology
