Abstract
The utility model provides a kind of preformed armouring shield line and curve connection joint, is related to electrification railway contact net field.The preformed armouring shield line and curve connection joint includes two and half round platform loop configuration:Inner side is semi-cylindrical, and outside is half round table surface, and there is guide groove half round table surface end.Preformed armouring shield line and curve connection joint of the present utility model is used for the adjacent junction of preformed armouring shield lines; ensure persistent at adjacent preformed armouring ceiling abutment points, solve the problems, such as existing adjacent preformed armouring shield lines abutment points guarded by location weakness.
Description
Technical field
Electrification railway contact net technical field is the utility model is related to, lines are protected more particularly to a kind of preformed armouring
Jointing.
Background technology
With the development of China's electric railway, to the performance requirement more and more higher of contact nets in electrified railways parts.
Existing preformed armouring shield lines solve overbridge, tunnel face clue protection problem substantially.But due to preformed armouring
Shield lines are limited by production technology and traffic condition, it is impossible to are processed into indefinite length, are often covered formed product length and do not surpass typically
Cross 5 meters.Therefore breakpoint be present at adjacent two sets preformed armouring shield lines abutment points, the breakpoint is the weakness to clue protection
Point.As foreign matter falls at the breakpoint, clue of easily burning.
Utility model content
The utility model provides a kind of preformed armouring shield line and curve connection joint, to solve existing protectiving scheme in breakpoint
The problem of protection weak spot be present in place.
For the above-mentioned purpose, on the one hand, it is (following that the utility model provides a kind of preformed armouring shield line and curve connection joint
Abbreviation jointing), the jointing includes two and half round platform loop configuration:Inner side is semi-cylindrical, and outside is half round platform
There is guide groove face, half round table surface end.
Further, the jointing material is copper alloy, aluminium alloy.
Further, the clue after can protecting lines internal layer or middle level with preformed armouring on the inside of the jointing is bonded.
Further, half round table surface end guide groove minimum point protects lines to clue axis distance with installing preformed armouring
Clue radius after outer layer is equal.
Further, half round table surface end guide groove quantity is equal with preformed armouring shield lines outer layer hank knotting radical.
The utility model has the beneficial effect that:
The utility model embodiment realizes reinforcement at preformed armouring shield lines adjoining breakpoint, compensate for lacking at breakpoint
Fall into, truly realize complete protection of the preformed armouring shield lines to clue.
Brief description of the drawings
Fig. 1 is a set of jointing of the utility model embodiment;
Fig. 2 is the utility model embodiment single-piece jointing side view;
Fig. 3 is that the preformed armouring for not installing jointing protects lines effect;
Fig. 4 is that a set of armouring of the utility model embodiment protects lines and jointing installation effect;
Fig. 5 is that neighboring armatures protect lines state effect after the utility model embodiment installs jointing.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further elaborated.It should be appreciated that this place
The specific embodiment of description only to explain the utility model, does not limit the utility model.
The jointing that the utility model embodiment is related to is a kind of contact nets in electrified railways part, contact net across
Used at adjacent two sets of preformed armouring shield lines abutment points at line bridge, tunnel face, solve existing preformed armouring shield line
The problem of weak is protected at bar jointing.
As shown in figure 3, after two sets of adjacent preformed armouring shield lines installations, due to connectionless joint, the position 3 in figure
At abutment points, two sets of preformed armouring shield lines are in discrete state.When foreign body falling is to the position above clue, easily
Clue is damaged, the position turns into the weak spot of route protection.
The jointing that the utility model embodiment as shown in Figure 1 is related to, including the round platform loop configuration of two pieces half, outside is
Half round table surface.
It is semi-cylindrical on the inside of jointing, semi-cylindrical can be with being mounted with preformed armour shown in position 2 as shown in Figure 2
Clue fitting after dress shield lines internal layer (or middle level).
Shown in position 1 as shown in Figure 2, there is guide groove on the outside of jointing.
As shown in Figure 1, 2, to ensure that protecting lines with armouring after jointing installation, electrochemical corrosion and stronger does not occur
Electric conductivity, jointing material should protect lines material according to preformed armouring and be selected, i.e., using copper alloy or aluminium alloy.
As shown in figure 4, a set of jointing is combined into installation with a set of preformed armouring shield lines in its right side, to ensure to be
The preformed armouring shield lines in the left side of installation are bonded with mounted preformed armouring shield lines, jointing guide groove is minimum
Clue radius after point installs preformed armouring shield lines to axis distance with right side is equal;And guide groove quantity must be with a left side
The preformed armouring shield lines outer layer hank knotting radical that side will install is equal.
As shown in figure 5, the preformed armouring in left side shield lines outer layer installs, outer layer hank knotting is in position 4 along protection joint
The round table surface rounding off of outside half, it is bonded by protecting lines outer layer with a set of preformed armouring on right side in position 5 after guide groove.
As can be seen from the above-described embodiment, the jointing of the utility model embodiment makes adjacent two sets of preformed armouring shields
Lines realize physical connection and electrical connection, eliminate weak spot, realize the complete protection to clue.
Obviously, those skilled in the art can carry out various changes and modification without departing from this practicality to the utility model
New spirit and scope.So, if these modifications and variations of the present utility model belong to the utility model claims and
Within the scope of its equivalent technologies, then the utility model is also intended to comprising including these changes and modification.
