Description
Technical field
The invention belongs to switching technique field.
Background technology
Light rail is a kind of important form of city rail construction, and develops track traffic the swiftest and the most violent in the world today
Form.The locomotive weight and handling capacity of passengers of light rail are smaller than general train, used rail light weight, every meter of only 50kg, because
This is called " light rail ".Urban light rail has the advantages that freight volume is big, speed is fast, pollutes small, less energy consumption, run on schedule, be safe.
Urban light rail forms rapid urban rail transit system with underground railway, city railway and other station designs.Light rail
Many fasteners can be used on track, most common fastener is bolt, and existing bolt is substantially from Japanese import, because Japanese
Bolt can bear prolonged vibratory impulse, the probability loosened is smaller, but this bolt one side cost is higher,
On the other hand can not avoid loosening completely, it is necessary to regular retorque.The shortcomings that this mode, is：In every case there is one
Bolt looseness, great potential safety hazard will be brought to city railcar, now at present in addition to frequency is tightened in increase, not effectively
The method that monitoring bolt looseness, specific aim tighten bolt.
The content of the invention
The invention is intended to provide a kind of conductivity ceramics switch of bolt looseness that can be on effective monitoring light rail.
A kind of conductivity ceramics construction of switch of this programme, is arranged in the inner chamber of bolt, bolt is tightened in the spiral shell of light rail part
Kong Zhong, the inner chamber of bolt are disposed with press head, diaphragm, piston, conductivity ceramics bar and sealed with wax from outside to inside, the press head
On be provided with puncture tip towards diaphragm, the Instant cement of liquid is filled between diaphragm and press head；The piston slides with inner chamber
Coordinate, air chamber is formed between diaphragm and piston, the inside of piston is embedded with warning lamp, chute, spiral shell are provided with the bar wall of bolt
The position relative with chute is provided with contact on the hole wall of hole, and the metal coordinated with slide is connected with the perisporium of piston and is slided
Piece, the metal slide plate are connected with warning lamp by electric wire；The conductivity ceramics bar is coaxially disposed with bolt, conductivity ceramics bar it is upper
End and piston clamping, and the conductivity ceramics bar upper end is connected with warning lamp by electric wire, the lower end of conductivity ceramics bar connects with sealing with wax
Touch；Described seal with wax is arranged at the accent of inner chamber, and screw bottom is embedded with and sealed with wax the power supply of contact, and the power supply passes through electricity with contact
Line connects；The press head, diaphragm, piston, Instant cement are Transparent color.
Beneficial effect：After bolt to be tightened in the present invention screw of light rail part, pressing press head causes puncture tip towards film
Piece is moved, and finally pierces through diaphragm so that the Instant cement of liquid is flowed into air chamber, continues to press, press head just promotes Instant cement
Extrusion piston so that piston moves, during due to original state, seal with wax with end in contact under conductivity ceramics bar, conductivity ceramics bar
Sealed with wax by after the extruding force of piston transmission with regard to piercing through, conductivity ceramics and electrical power contacts, at the same time, the metal connected on piston
Slide plate also just slides into the position of contact, and then the circuit of the warning lamp in piston is connected, and warning lamp is shinny, and operating personnel see
Observe warning lamp it is shinny after, stopping continues to press, and keeps current pressing dynamics so that Instant cement solidifies, after Instant cement solidification just
So that piston is bonded in inner chamber, the circuit of warning lamp is always maintained at on-state.When there is bolt looseness, conductivity ceramics bar one
Denier separates with power supply, and the circuit of warning lamp just disconnects, and warning lamp extinguishes, and whether maintenance personal just monitors bolt on light rail with this
Loosen.The present invention is simple in construction, can quickly judge whether bolt loosens.
Further, the bolt includes head and bar portion, and the inner chamber is included positioned at the accommodating chamber on head and positioned at bar
The mobile cavity in portion；The press head, diaphragm and Instant cement are respectively positioned in accommodating chamber.
Further, the chute is located in the cavity wall of the mobile cavity of bolt, when piston moves, drives metal slide plate in chute
Interior movement.
Further, the positive pole of the power supply is in contact with sealing with wax, the negative pole and contact portion of power supply, when conductivity ceramics bar with
When positive pole of sealing with wax releases, contact can contact with metal slide plate, so that warning lamp energization is shinny.
Further, the diaphragm and piston are made by transparent resin, and material price is cheap to be easy to get；The warning lamp is
LED, it is not easy to damage.
Brief description of the drawings
Fig. 1 is a kind of structural representation of conductivity ceramics construction of switch of the present invention.
Embodiment
Below by embodiment, the present invention is further detailed explanation：
Reference in Figure of description includes：Bolt 1, press head 2, puncture tip 2-1, Instant cement 3, diaphragm 4, air chamber
5th, piston 6, warning lamp 7, metal slide plate 8, conductivity ceramics bar 9, seal with wax 10, light rail components A, light rail part B, contact C, power supply D.
A kind of conductivity ceramics construction of switch, in bolt 1, the bolt 1 includes head and bar portion, and receiving is provided with head
Chamber, bar portion outer wall are thread segment, and the mobile cavity communicated with accommodating chamber is provided with inside bar portion.As shown in Fig. 1, erected in light rail components A
Bolt hole is provided with to bolt blind hole is provided with, on light rail part B is vertical, bolt blind hole and bolt hole overlap, the bar portion of bolt 1
It is inserted into bolt blind hole and tightens after run through bolt through hole.
As described in Figure 1, conductivity ceramics switch from top to bottom includes press head 2, diaphragm 4, piston 6, conductivity ceramics bar successively
9th, 10 are sealed with wax.Press head 2 is made up of transparent elastic caoutchouc and is adhered to the upper end accent of accommodating chamber, the downside of press head 2
Puncture tip 2-1 is convexed to form on face.Diaphragm 4 is made up of transparent resin flake, and diaphragm 4 is adhered in accommodating chamber cavity wall, pressing
The Instant cement 3 of transparent liquid is filled between first 2 and diaphragm 4.Piston 6 is made up of transparent resin, and piston 6 is slided with mobile cavity
It is dynamic to coordinate, air is filled between piston 6 and diaphragm 4 and forms air chamber 5.The inside of piston 6 is embedded with warning lamp 7 and (selects LED
Bubble), the downside of piston 6 is connected with vertical conductivity ceramics bar 9, and the upper end of conductivity ceramics bar 9 is connected with warning lamp 7 by electric wire
Connect, the lower end of conductivity ceramics bar 9 10 contacts with sealing with wax.One section of chute is vertically provided with the cavity wall of mobile cavity, is blocked on the perisporium of piston 6
Metal slide plate 8 is connected to, the metal slide plate 8 coordinates with slide, and metal slide plate 8 passes through electric wire with the warning lamp 7 inside piston 6
