Abstract
The utility model belongs to the technical field of diversion bar expansion joints, and discloses a continuous bidirectional end expansion joint. The continuous bidirectional end expansion joint is mainly and technically characterized by comprising two handshake junctions, wherein the front ends of the handshake junctions are staggered and overlapped, and the tail parts of the handshake junctions and diversion bars are fixed; contact wires extending from the diversion bars are fixedly arranged at the lower ends of the handshake junctions through fixed wire clips; an annular electrical connecting bar fixing frame is arranged above the handshake junctions; and the two handshake junctions are connected through a limitable sliding connection mechanism. The two diversion bars slide along a direction away from each other when being contracted in winter, and slide along a direction close to each other when being expanded in hot summer, so that pantographs can be ensured to contact with side contact wires or the contact wires all the time no matter whether the diversion bars are expanded or contracted, an arc discharge phenomenon is avoided, and the service life of each diversion bar is prolonged.
Description
Technical field
The utility model belongs to water conservancy diversion row expansion joints technical field, relates to the two-way end expansion joints of continous way concretely.
Background technology
Electrified contacting nets in short narrow obstruction clearance criteria such as tunnel, low latitude and subway, electric power is arranged to provide in the most employing lower end fixedly water conservancy diversion of contact wire, present water conservancy diversion row is in order to solve the problem of expanding with heat and contract with cold, adopt the adjacent water conservancy diversion row of multistage to be formed by connecting, between the adjacent water conservancy diversion row overlapping about 6 meters, so not only cause waste of material, increase cost, and when high speed train travels, being discharged to another water conservancy diversion from a water conservancy diversion arranges when excessive, cause the arcing phenomenon to take place, reduce water conservancy diversion row's service life.
The utility model content
The technical matters that the utility model solves just provide a kind of simple in structure, cost is low, the two-way end expansion joints of continous way in light weight, that do not produce arcing phenomenon, long service life.
For solving the problems of the technologies described above, the technical scheme that the utility model proposes is: the knot of shaking hands of comprise that two front ends are overlapping, afterbody and water conservancy diversion row are fixing, described shaking hands forged end and fixedly had by water conservancy diversion by fixing clamper and arrange extended contact wire, the described side of tying of shaking hands is provided with annular electro and connects row's fixed mount, described two shake hands between the knot by can be spacing the connection of sliding block joint mechanism.
Its additional technical feature is:
Two described shake hands to tie have long slot bore, be provided with bolt hole in described long slot bore the place ahead, the bolt hole of the described knot of shaking hands is relative with the long slot bore of another knot of shaking hands, described can be spacing sliding block joint mechanism shake hands and tie first bolt and second bolt of bolts hole for inserting two respectively;
Described first bolt and second bolt are provided with holddown spring;
First bolt and second bolt at described long slot bore place are with the axle sleeve that inside studs with oilless metal;
Be connected with backing plate described shaking hands between knot lateral surface and the described water conservancy diversion row, described backing plate be connected by cross bolts between described water conservancy diversion is arranged;
Described two the knot arranged outside of shaking hands housing is arranged.
The two-way end expansion joints of the continous way that the utility model provides, compare with prior art and to have the following advantages: one, owing to comprise that two front ends are overlapping, the knot of shaking hands that afterbody and water conservancy diversion row are fixing, described shaking hands forged end and fixedly had by water conservancy diversion by fixing clamper and arrange extended contact wire, the described side of tying of shaking hands is provided with annular electro and connects row's fixed mount, described two shake hands between the knot by can be spacing the connection of sliding block joint mechanism, when winter, water conservancy diversion row shortened, two water conservancy diversion row along away from direction slide, when the summer of sweltering heat, water conservancy diversion row extended, two water conservancy diversion rows slide along close direction, like this, no matter water conservancy diversion row elongates or shortens, can both guarantee that pantograph contacts with side contacts line or contact wire all the time, can not cause the generation of arcing phenomenon, prolong its service life; They are two years old, since two described shake hands to tie have long slot bore, be provided with bolt hole in described long slot bore the place ahead, the bolt hole of the described knot of shaking hands is relative with the long slot bore of another knot of shaking hands, described can be spacing sliding block joint mechanism for inserting first bolt and second bolt of two knot bolts hole of shaking hands respectively, both guaranteed two relative slips of shaking hands between the knot, and avoided again misplacing in the sliding process, and processed convenient; Its three because described first bolt and second bolt are provided with holddown spring, make the contact resistance of junction of two knots of shaking hands reduce greatly; Its four owing to be connected with backing plate described shaking hands between knot lateral surface and the described water conservancy diversion row, is connected by cross bolts between described backing plate and the described water conservancy diversion row, like this, not only process simply, be convenient to construct, and fixation; Its five since described two shake hands the knot arranged outside housing is arranged, prolonged shake hands the knot service life.
