According to the invention, the protection wire is arranged at the center of the bolt, so that the broken or loosened bolt can be prevented from falling off and flying out when the bolt is broken, thereby preventing the broken bolt from damaging a line facility or a line-adjacent running vehicle and the like, and perfectly eliminating the hidden danger of damage to the vehicle and other equipment and personnel caused by the breaking or loosening of the bolt.
Description
Technical Field
The invention relates to railway safety, in particular to a bolt for a railway vehicle, which has the functions of fracture loosening alarm and falling-off prevention and flying-out.
Background
At present, bolts for railway locomotives and vehicles at home and abroad have no fracture or loosening alarm function, and designers usually adopt a method for increasing the number of bolts to ensure the safe use of the bolt connection parts. Under the previous operation condition, the dynamic stress born by the bolt is small, the bolt is rarely broken, and the potential safety hazard is not too great.
With the improvement of the running speed of the railway trains in China, the dynamic load borne by the bolts is increased, the conditions of bolt breakage or loosening are increased gradually, and the broken bolts pose a threat to the line infrastructure and the safety of the train running on the line due to the higher running speed of the trains.
Disclosure of Invention
In order to overcome the existing defects, the invention provides a bolt for a railway vehicle, which has the functions of fracture loosening alarm and falling-off prevention and flying-out.
The utility model provides a bolt for railway vehicle with fracture is not hard up report to police and anti-drop departure function, includes hollow bolt, safety line and alarm signal generator, alarm signal generator passes through the bolt fastening in hollow bolt top, the inside cavity that sets up of hollow bolt, the safety line setting is in the bolt cavity, and wherein, safety line one end is fixed in hollow bolt bottom, and the safety line other end sets up in alarm signal generator inside.
The alarm signal generator is internally provided with a first electrode and a second electrode, the first electrode and the second electrode are respectively arranged at the bottom ends of two sides of the alarm signal generator, and the lower end of the first electrode is provided with an elastic supporting pad.
The upper end of the first electrode is provided with a pressing plate, the middle of the pressing plate is provided with a through hole, and the safety line penetrates through the through hole and is fixed at the upper end of the pressing plate.
The alarm signal generator is internally provided with an integrated circuit board, wherein the upper end of the integrated circuit board is provided with a wireless power transmitter, the lower end of the integrated circuit board is provided with a button cell, and the first electrode and the second electrode are respectively connected with the integrated circuit board.
The invention aims to realize the protection function of the broken bolt and prevent the broken bolt from falling off and flying out by arranging the protection wire inside the bolt. Through arranging the protection wire inside the bolt, the protection function of the bolt after loosening is realized, and the bolt can be prevented from further loosening and falling off. The protection wire in a tightening state drives the switch to be closed to send an alarm signal, so that the alarm circuit is in a closing state at ordinary times and is closed when broken or loosened, the power consumption is low, and the reliability of breaking alarm is high. The alarm signal is sent out through the tensioning protection wire at the end part, and the alarm signal disappears after the protection wire is released, so that whether the state of the bolt alarm device is normal or not can be conveniently confirmed, and the bolt can be overhauled without being disassembled.

Fig. 2 is a schematic diagram of a bolt for a railway vehicle with fracture loosening alarm and anti-drop-out function when broken.
Detailed Description
The bolt for railway vehicles provided by the invention has the functions of fracture loosening alarm and falling-off and flying-out prevention and is described in detail below with reference to the accompanying drawings and specific embodiments.
Fig. 1 shows a bolt for railway vehicle with fracture looseness warning and anti-drop fly-out function, including hollow bolt 1, safety line 2 and alarm signal generator 3, alarm signal generator 3 is fixed in hollow bolt 1 top through bolt 11, hollow bolt 1 inside sets up the cavity, and safety line 2 sets up in the cavity of bolt 1, and wherein, safety line 2 one end is fixed in hollow bolt 1 bottom, and the safety line 2 other end sets up in alarm signal generator 3 inside.
The alarm signal generator 3 is internally provided with a first electrode 8 and a second electrode 9, the first electrode 8 and the second electrode 9 are respectively arranged at the bottom ends of two sides inside the alarm signal generator 3, and the lower end of the first electrode 8 is provided with an elastic supporting pad 10.
The upper end of the first electrode 8 is provided with a pressing plate 7, the middle part of the pressing plate 7 is provided with a through hole, and the safety line 2 passes through the through hole and is fixed at the upper end of the pressing plate 7.
The alarm signal generator 3 is internally provided with an integrated circuit board 5, wherein the upper end of the integrated circuit board 5 is provided with a wireless power transmitter 6, the lower end of the integrated circuit board 5 is provided with a button cell 4, and the first electrode 8 and the second electrode 9 are respectively connected with the integrated circuit board 5.
The safety line 2 is arranged inside the hollow bolt 1, the alarm signal generator 3 is arranged at the end part of the bolt, when the hollow bolt 1 is intact, the safety line 2 is in a loose state, the alarm signal generator 3 is in a disconnection state, when the hollow bolt 1 breaks or loosens, the safety line 2 is tightened, the alarm signal generator 3 is closed, an alarm signal is sent, meanwhile, the safety line 2 protects the broken bolt, the broken part is prevented from falling off, and further loosening and falling off of the loose bolt can be avoided.
When the hollow bolt 1 is intact, the safety wire 2 is in a relaxed state, the first electrode 8 and the second electrode 9 are not in contact, the whole circuit is in an open state, and the signal generator is in a closed state.
