There are many types of fish plate bolts, and different kinds of switches, with different characteristics, can be laid according to production requirements, laying environment, laying different kinds of switches. fish plate bolts is also a kind of turnout provided by our company, although compared with other kinds of turnout, there are many characteristics and advantages, but there are some inevitable shortcomings. So what are the main problems with fish plate bolts?
1. Under normal circumstances, the straight direction of switch opening is called positioning, and the side direction of switch opening is called reverse; In special cases, the opening of the side direction is called positioning, and the opening of the straight direction is called reverse position. The fish plate bolts can be opened in three directions. There is no definition of the position of the fixed reverse position. However, the opening position of the fish plate bolts should also be defined in the regulations of urban rail transit.
2, fish plate bolts is a more complex type of turnout, the relevant railway departments do not clearly specify the corresponding hook lock. fish plate bolts are used in urban rail transit. Two new types of hook locks are needed to open the straight position at the same time. A hook lock bolts that cannot lock the basic rail, long rail and short rail at the same time cannot be used.
3. Manual switch operation. The standard operation of the wrench according to the original one look, two pull, three confirm and four display is also different from the previous provisions. When the fish plate bolts are operated manually, the two switch machines must be operated at the same time. According to the actual situation of the field switch, there is a sequence of the two switch machines during switch conversion. The number displayed next to the switch on the man-machine interface is the switch number, not the number of the outdoor switch switch machine. The switch machine of fish plate bolts is set on the other side of its corresponding switch, and the setting method is different from other switch switch machines.
In fact, whether it is fish plate bolts, or other kinds of turnout, in the process of application, in order to avoid frequent failures, in addition to mastering the correct operation of fish plate bolts, it is also necessary to do regular inspection and maintenance.
