Abstract
The utility model relates in a kind of tunnel not digging does not invade limit contact net anchorage falling mound compensation restraint device.The compensating device that casts anchor need dig tunnel cross-section, and guarantee does not invade driving gauge after installing.The utility model comprises anchorage steel wire rope and the falling mound string established is hung in end, and the longitudinal both sides of falling mound string are provided with two vertically symmetrical guide pipes, and falling mound ganged up the track adjusting wheel amplexis of both sides to guide pipe; Two upper and lower two ends of guide pipe are individually fixed in upper bed-plate and lower bottom base, and upper bed-plate and lower bottom base are fixed on tunnel inner wall; Fall the range of motion surrounded at guide pipe and Up/down base when sticking together string lifting, therefore falling mound string can not invade driving gauge.The utility model adopts four groups of track adjusting wheels to add the structure of DLC, guides pendant falling mound vertical motion, while meeting the compensate function that casts anchor, limits falling mound and swings, and avoids invading driving gauge.
Description
Technical field
the utility model belongs to electrification railway contact net technical field, is specifically related to not dig in a kind of tunnel do not invade limit contact net anchorage falling mound compensation restraint device.
Background technology
Electrification railway contact net is outdoor power equipment supply.Be bullied gentle solar radiation, the wire of contact system and catenary can expand with heat and contract with cold, and cause length of wires to change.Because contact net system requires wire and catenary identical tension, therefore tension compensating to be carried out at each overlap place.Contact net anchorage generally adopts gravity type boat davit to compensate, and the compensating device that casts anchor is the gravity relying on falling mound, is realized tensioning and the flexible compensation of wire rod, guarantee contact system on period identical tension by assembly pulley or ratchet group no-load voltage ratio.
Tradition is casted anchor, and volume is large, stroke is long because pendant sticks together for compensating device, and take up room many, need Civil Specialities to carry out tunnel cross-section and dig, the device after guarantee installation does not invade driving gauge; Also to install protective cover additional for the protection during runing and antitheft simultaneously.Due to high ferro and Tunnel in Passenger Dedicated Railway Line, to dig cost very high, and therefore development of new does not dig and do not invade limit pendant and stick together that to compensate restraint device necessary.
Summary of the invention
The purpose of this utility model is to provide in a kind of tunnel not dig does not invade limit contact net anchorage falling mound compensation restraint device, solves the problem that must dig in tunnel in prior art and could install and cast anchor and fall and stick together.
The technical scheme that the utility model adopts is:
Do not dig in a kind of tunnel and do not invade limit contact net anchorage falling mound and compensate restraint device, comprise anchorage steel wire rope and the falling mound string established is hung in end, it is characterized in that:
Falling mound displacement is outside tunnel driving gauge, and the longitudinal both sides of falling mound string are provided with the guide pipe of two vertically symmetrical isometrical tubulars, and falling mound ganged up the track adjusting wheel amplexis of both sides to guide pipe;
Two upper and lower two ends of guide pipe are individually fixed in upper bed-plate and lower bottom base, and upper bed-plate and lower bottom base are fixed on tunnel inner wall.
Tunnel inner wall above upper bed-plate is fixed with pulley, and anchorage steel wire rope is walked around pulley jib and is established falling mound string.
Falling mound string comprises the falling mound of the two string sheets be longitudinally set up in parallel, and falling mound tandem arrangement is in plummet rod and be placed in falling mound framework;
The base of track adjusting wheel is welded on falling mound framework.
Plummet rod top is connected to link plate, and link plate top is connected with anchorage steel wire rope end by wire clamp.
The utility model has the following advantages:
1, adopt plummet stone roller or iron falling mound to substitute traditional concrete weights, reduce counterweight volume, realize higher counterweight density;
2, adopt four groups of track adjusting wheels to add the structure of DLC, guide pendant falling mound vertical motion.While meeting the compensate function that casts anchor, limit falling mound and swing, avoid invading driving gauge.
3, track adjusting wheel adopts integrated anticreep, anti theft design with falling mound framework, eliminates traditional anti-theft net, decreases equipment volume, and have automatic deviation rectifying function.
4, the embedded plain bearing of track adjusting wheel rotor, limiter tube center, avoids traditional limit frame (channel-section steel) track adjusting wheel catching phenomenon.

Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is described in detail.
According to railway " skill rule " regulation, in tunnel, any equipment must not invade tunnel driving gauge 1.Do not dig in a kind of tunnel that the utility model relates to and do not invade limit contact net anchorage falling mound compensation restraint device, comprise anchorage steel wire rope 2 and the falling mound string 6 established is hung in end, falling mound string 6 is positioned at outside tunnel driving gauge 1, the longitudinal both sides of falling mound string 6 are provided with the guide pipe 8 of two vertically symmetrical isometrical tubulars, and falling mound string 6 passes through track adjusting wheel 14 amplexis of both sides to guide pipe 8.Track adjusting wheel 14 is symmetrical arranged, each upper and lower two groups of both sides.Two guide pipe about 8 two ends are individually fixed in upper bed-plate 4 and lower bottom base 7, and upper bed-plate 4 and lower bottom base 7 are fixed on tunnel inner wall.
Tunnel inner wall above upper bed-plate 4 is fixed with pulley 3, anchorage steel wire rope 2 is walked around pulley 3 and is hung and establish falling mound string 6.Falling mound string 6 comprises the falling mound 13 of the two string sheets be longitudinally set up in parallel, and adopt irony or plumbous matter pendant to stick together, fall than conventional cement the density that sticks together large, equivalent weight lower volume is less.Falling mound 13 tandem arrangement is in plummet rod 11 and be placed in falling mound framework 12.Plummet rod 11 top is connected to link plate 10, and link plate 10 top is connected with anchorage steel wire rope 2 end by wire clamp 9.The base of track adjusting wheel 14 and the pendant framework 12 that sticks together is integrally welded, effectively antitheft.Eliminate traditional anti-theft net, reduce equipment volume further.The embedded plain bearing of rotor 15 of track adjusting wheel 14, restricted guidance pipe 8 center, avoids track adjusting wheel 14 catching phenomenon.
When pendant sticks together string 6 generation lifting, fall the framework 12 that sticks together and drive four groups of track adjusting wheels 14 to slide up and down along guide pipe 8.Because other directions all suffer restraints, pendant sticks together motion in falling mound string range of movement 5 that string 6 can only surround at guide pipe 8, upper bed-plate 4 and lower bottom base 7, and therefore falling mound string 6 can not invade tunnel and to drive a vehicle gauge 1.
Content of the present utility model is not limited to cited by embodiment, and the conversion of those of ordinary skill in the art by reading the utility model specification sheets to any equivalence that technical solutions of the utility model are taked, is claim of the present utility model and contains.
