Abstract
The utility model relates to a front portion anchoring device used for a climbing crane, belongs to the field of cranes, and in particular relates to a climbing crane used for erecting steel truss arch bridges. The front portion anchoring device is composed by two preloaded anchoring pulling plates, an anchoring box girder and a pulling plate assembly. The two preloaded anchoring pulling plates are symmetrically arranged on two sides of a front portion walking and traction device through shaft. When the climbing crane climbs to a working position on an arch, steel plates arranged on two sides of the anchoring box girder are welded on corresponding positions of an arched girder box girder. In order to prevent the crane from sliding down along the arch after the crane is in position, the preloaded anchoring pulling plates on a walking trolley through shaft and the pulling plate assembly on the anchoring box girder are connected through hinge pins, and accordingly the aim of locking anchoring is achieved. The force situation of the walking trolley through shaft is good, and accordingly single plate pulling plates are only mounted on two sides of the walking trolley through shaft. The pulling plate assembly formed by a pair of double plates is arranged among two sides of the anchoring box girder and the preloaded anchoring pulling plates to form a double shearing structure, thereby enabling the hinge pins connecting the pulling plates to be good in force situation and being safer and more reliable.
Description
Technical field
A kind of anterior anchor fitting that is used for climbing crane of the utility model belongs to the hoisting crane field, and particularly steel truss arched bridge sets up and uses climbing crane.
Background technology
When steel truss arched bridge is set a roof beam in place and is set a roof beam in place on the steel braced arch with hoisting crane; For make hoisting crane on the ramp construction with the level land on the same convenient; Require the top bottom-disc of hoisting crane to keep horizontality with the vault slope change; And low bottom-disc and camber one sections level of incline, this structure can can't be carried out lifting operation like no failure-free anchor structure fixed crane because of overcoming sliding force when then the hoisting crane machine is worked.For making hoisting crane safe and reliable being fixed on the arched girder of when work, design a kind of simple in structurely, anchoring is convenient, and is safe, safeguards that simple anterior anchor fitting is just imperative.
The utility model content
The utility model patent purpose provides a kind of anterior anchor fitting that is used for climbing crane, safe and reliable being fixed on the arched girder in the time of can not only making hoisting crane work, and also this anterior anchor fitting is simple in structure, and anchoring is convenient.
The utility model patented technology scheme is following:
The anterior anchor fitting of the utility model; Form by prepackage anchoring arm-tie, anchoring case beam and arm-tie assembly; Pre-install anchoring arm-tie symmetric arrangement traveling forwardly and draw gear axis both sides for two; Anchoring case beam is fixed in the relevant position of arched girder case beam, and prepackage anchoring arm-tie connects with bearing pin through the arm-tie assembly with anchoring case beam.
Described arm-tie assembly is made up of a pair of pair of plate.
The anchoring that the anterior anchor fitting of the utility model patent is used for climbing crane when on arched girder, working.Climb arch when reaching control position at climbing crane, anchoring case beam both sides steel plate is welded on the relevant position of arched girder case beam.For preventing to glide along arch behind the hoisting crane erect-position,, play the purpose of locking anchoring with linking up with bearing pin between the arm-tie assembly on arm-tie on the running truck axis and the anchoring case beam.Because running truck axis stressing conditions is good, so only the veneer arm-tie is installed in its both sides.The arm-tie assembly that adopts a pair of pair of plate to form between anchoring case beam both sides and the prepackage anchoring arm-tie forms the double shear structure, makes the bearing pin stressing conditions that connects arm-tie good, more safe and reliable.

The specific embodiment
How combine accompanying drawing to further specify the utility model patent implements at present:
The anchoring that the anterior anchor fitting of the utility model is used for climbing crane when on arched girder, working.Two prepackage anchoring arm-ties 3 are with the both sides of the axis 2 of the traveling forwardly of pivotally attached mode symmetric arrangement and draw gear 1, climb at climbing crane and encircle when reaching control position, anchoring case beam 5 both sides steel plates are welded on the relevant position of arched girder case beam 6.For preventing behind the hoisting crane erect-position along arch along gliding, the arm-tie assembly 4 usefulness bearing pins 7 that the arm-tie 3 and the steel plate on the anchoring case beam 5 of axis 2 both sides of anterior traveling and draw gear 1 are formed through a pair of pair of plate link up, and reach the purpose that locks anchoring.Implement relevant operation after the locking anchoring again.
