Description
Technical field
The present utility model relates to a kind of suspension bridge and puts rope traction device, belongs to equipment for bridge construction and manufactures and designs field.
Background technology
Suspension bridge has another name called suspension bridge, refers to using to hang and be anchored in the cable of two sides (or bridge two ends) as the bridge of the main supporting member of superstructure by Sarasota.The main supporting member of suspension bridge is suspension cable, suspension cable is to be combined by a lot of strands, each strand is produced by production plant and around Suo Panshang, then transporting to building site emits and sets up, by Sarasota, hang and be anchored in two sides, frame rope process is that main push-towing rope one end is packed into and pulled on device, pulls on the haulage cable that device is connected to the hoist engine that is fixed on two sides, operation, is drawn to opposite bank by strand by a bank back and forth.Pull the Main Function of device for strand and haulage cable are linked up, the tractive force of pull rope passes on strand by pulling device, pulls device traction strand, and pulls device and can pass through smoothly a plurality of guy guide wheel group of full-bridge.
Chinese patent CN202466415U discloses a kind of dorsal funciculus rope tail and has pulled device, it pulls balance major axis and balance weight has been installed on device, but for the rope head-clamp quality of the straw line thigh that comes into the picture generally at 200 ~ 500kg, because whole suspension is flexible, pull rope tensioning and loose or can cause the swing of strand and depart from draught line and whole piece wire rope vibration, swing that also can straw line thigh and unfavorable to strand.
Summary of the invention
The utility model provides the traction of a kind of suspension bridge strand cable laying with pulling device, and solves and because of pull rope tensioning with when loose, can cause and pull device upset and whole piece wire rope vibrates, swing that also can straw line thigh.
Another goal of the invention of the present utility model is to provide a kind of device that pulls to pulley groove that can be smoothly can cross guide wheel group.
The utility model is achieved in that
The traction of strand cable laying, with pulling a device, comprises wedge joint link 1, wire rope wedge form joint 2, front shuttle pipe 3, rear shuttle pipe 4, upper balance adjustment screw axis 5, upper equilibrate counterweight 6, traction ear 7; Wedge joint link 1, front link rod 11, rear link rod 12, horizontal link rod 13 are connected and are formed the triangle rod member framework that pulls device by bearing pin, the connecting mode that pulls device and pull rope is that pull rope passes through front shuttle pipe 3, rear shuttle pipe 4, and wire rope wedge form joint 2 connects with traction ear 7 by bearing pin through trailed strand rope head-clamp; Pull the bottom on balance adjustment screw axis 5 on device and be also provided with lower equilibrate counterweight 8 and the lower balance adjustment screw axis 9 connecting through lower balance adjustment screw axis 10.
The head of front shuttle pipe 3, rear shuttle pipe 4 is tapered.
The utility model arranges lower equilibrate counterweight 8, lower balance adjustment screw axis 9 by having increased, and to trailer system ballast and balance, makes to pull device and strand stable operation; Simultaneously the utility model is by tapered the head of front shuttle pipe 3, rear shuttle pipe 4, so as to pull device can be smoothly by guide wheel group to filling pulley race.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is top view of the present utility model;
Fig. 3 is left view of the present utility model;
In figure, be designated: horizontal link rod 14 rope head-clamp 15 strand 16 wire rope of the equilibrate counterweight 7 traction rear link rod 13 of the front link rod 12 of 10 times balance adjustment screw axis 11 of 9 times balance adjustment screw axis of 8 times equilibrate counterweights of ear on balance adjustment screw axis 6 on the rear shuttle pipe 5 of the 1 wedge joint link front shuttle pipe 4 of 2 wire rope wedge form joint 3.
The specific embodiment
Pulling device and the connecting mode of pull rope and be pull rope passes through forward and backward shuttle pipe and connects with wire rope wedge form joint, trailed strand rope head-clamp connects with traction ear by bearing pin, and the drive of hoist engine haulage cable pulls device and moves back and forth between suspension bridge two sides.
Front shuttle pipe 3, rear shuttle pipe 4 its head design are tapered, so as to pull device can be smoothly by guide wheel group to dress pulley race, the parts eccentric weight balances such as upper balance adjustment screw axis 5,6 pairs of the right gusset pieces of upper equilibrate counterweight, regulate screw mandrel to regulate left and right balance, center and the shuttle pipe of traction ear 7 are designed on a center line, make the pull rope of the strand that drawn and hoist engine at grade stressed, avoid pull rope to depart from draught line, coming into the picture, (rope head-clamp is a kind of head and a kind of device that pulls device and link up of keeping vegetarian by rope head-clamp for the rope head of straw line thigh, rope head is fixed on rope head-clamp, rope head-clamp with to draw ear 7 be to connect by bearing pin) link up with traction ear 7, because whole suspension is flexible, pull rope tensioning and loose meeting cause the swing of strand and depart from draught line, for overcoming swing and departing from the imbalance that draught line causes, lower equilibrate counterweight 8 is set in the bottom that pulls device, lower balance weight boatswain chair 9, lower balance adjustment screw axis 10, to trailer system ballast and balance, make to pull device and strand stable operation.
Wedge joint link 1, front link rod 11, rear link rod 12, horizontal link rod 13 etc. are connected and are formed the triangle rod member framework that pulls device by bearing pin, the pull rope of hoist engine is fixed on the wire rope wedge form joint 2 that pulls device by front shuttle pipe 3, rear shuttle pipe 4, makes the pull rope that pulls device and hoist engine be connected into integral body; Equilibrate counterweight 6 on balance screw axis in adjusting, make to pull device when zero load in equilibrium state; Lower balance weight is to link up with upper balance adjustment screw axis 5 by lower balance weight boatswain chair 9; The rope head-clamp of trailed strand is fixed on the traction ear 7 that pulls device with bearing pin; Regulate the equilibrate counterweight 8 on lower balance screw axis 10, make to pull device when load condition in equilibrium state; By twice difference balance, pull device complete in desirable equilibrium state before operation; Pull device and mix after certain counterweight 8, and the below that is positioned at rope head of counterweight 8, overcome and pulled that device overturns in running under power process and the vibration of whole piece wire rope, the stable strand that carries out involves to draw and puts rope.
As can be seen here; the utility model pulls device and has realized and put rope and pull traction function and guarantee to put the reliable and stable operation in rope process; above institute art the utility model is the preferential embodiment that pulls apparatus; should be understood that; do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
