Abstract
The invention discloses a front anchoring device for a climbing crane, which belongs to the field of cranes and particularly relates to a climbing crane for erecting steel-truss arch bridges. The front anchoring device comprises pre-mounted anchoring pulling plates, an anchoring box girder and pulling plate components, the two pre-mounted anchoring pulling plates are symmetrically arranged on two sides of a through shaft of a front walking and traction device, steel plates on two sides of the anchoring box girder are welded at corresponding positions of an arch bridge box girder when the climbing crane which climbs an arch reaches a working position, the pre-mounted anchoring pulling plates on the through shaft of the walking trolley are connected with the pulling plate components on the anchoring box girder by hinge pins in order to prevent the crane from downwards slipping along the arch after the crane stands, and the purposes of locking and anchoring are achieved. In addition, the stress condition of the through shaft of the walking trolley is fine, accordingly, the single-plate type pulling plates are only mounted on the two sides of the through shaft, a double-shearing structure is formed between each of two sides of the anchoring box girder and the corresponding pre-mounted anchoring pulling plate by the aid of the corresponding pulling plate component consisting of a pair of double plates, the hinge pins connected with the pulling plates are stressed well, and the front anchoring device is safer and more reliable.
Description
Technical field
A kind of anterior anchor fitting that is used for climbing crane of the present invention 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.
Summary of the invention
Patent purpose of the present invention 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.
Patented technology scheme of the present invention is following:
The anterior anchor fitting of the present invention; 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 patent of the present invention 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.

Fig. 2 climbing crane of the present invention is with anterior anchor fitting birds-eye view
The specific embodiment
How combine accompanying drawing to further specify patent of the present invention implements at present:
The anchoring that the anterior anchor fitting of the present invention 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.
Claims (2)
1. anterior anchor fitting that is used for climbing crane; Form by prepackage anchoring arm-tie, anchoring case beam and arm-tie assembly; It is characterized in that two prepackage anchoring arm-tie symmetric arrangement travelings forwardly and draw gear axis both sides; 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.
2. a kind of anterior anchor fitting that is used for climbing crane according to claim 1 is characterized in that the arm-tie assembly is made up of a pair of pair of plate.
