Abstract
The utility model relates to a combined hanging basket for checking a steel truss bridge, and belongs to the field of bridge check maintenance devices. For the combined hanging basket, a left connection frame sleeve and a right connection frame sleeve are correspondingly nested outside two hanging baskets, and can horizontally move left and right relative to the hanging baskets through small rollers, corresponding upper and lower connection vertical rods of the left and right connection frame sleeves are fastened, combined and connected to form an integral hanging basket through connection plates, a hoisting steel wire rope surrounds a safety lock, one end of the hoisting steel wire rope is connected with a transverse bar of each hanging basket, and the other end of the hoisting steel wire rope is connected with a check trolley frame bicycle through a fixed pulley, so that the combined hanging basket smoothly lifts up and down along the hoisting steel wire rope and has the advantages of simple and convenient design, convenience for mounting, as well as safety and reliability. According to the combined hanging basket for checking the steel truss bridge, the left hanging basket and the right hanging basket are integrated through the two connection plates, so that a checking and maintaining space of a worker is large, bridge top surface inclined strut joints can be comprehensively and continuously checked and maintained, an overhauling operation can be successfully finished, and operation efficiency is high.
Description
Technical field
A kind of combination hanging basket that is used to check steel purlin bridge of the utility model belongs to bridge inspection maintenance prevention field.
Background technology
Along with the more and more attention to the bridge security problem, the importance of bridge detection operation is increasing.Its major function is for comprehensively to check, to repair each structure of bridge, for bridge security provides safeguard.The maintenance content comprises member whether torsional deformation, local damage; Rivet and bolt have non-loosening, come off and rupture, and whether node slides, mistake is split; Weld edge has flawless or disengagement; Skin of paint has flawless, peeling, comes off, and member has non-corroding etc.
At present, the steel truss girder structure is widely used on bridge floor.For steel purlin bridge; Because the particularity of its structure; The diagonal brace J of two square crossings is divided into four holes with every joint bridge end face I, and referring to Fig. 3, hanging basket can only drop to the appropriate location from each hole diagonal brace crossbar contact K is checked generally speaking; Yet at present general hanging basket since can not drop to node K under; So the maintainer needs the inclination body to come this node K place is checked and safeguards in hanging basket, not only therefore operating difficulties but also dangerous big needs exploitation can arrive the safe hanging basket that keeps in repair and safeguard under the node easily.
The utility model content
The purpose of the utility model provides a kind of combination hanging basket that is used to check steel purlin bridge, can safe ready ground be implemented inspection and safeguard by bridge end face diagonal brace interconnecting part through this hanging basket.
The utility model purpose realizes through following technical scheme:
The utility model is used to check the combination hanging basket of steel purlin bridge, is made up of hanging basket, link cover and wire rope, and characteristics are to be provided with about two link covers, and corresponding upper and lower connection montant and bracing diagonal are arranged, and its upper and lower level frame respectively is provided with trundle; The hanging basket two ends have spacing bumper and whippletree respectively; Spacing bumper is equipped with safety lock; About the corresponding outsides that are nested in two hanging baskets of two links cover; And move relative to the hanging basket left and right horizontal through trundle, with junction plate with about fastening being connected of corresponding upper and lower connection montant of two link covers be integral hanging basket, hoist rope is walked around safety lock one of which end and is connected with the hanging basket whippletree; The other end is connected with inspection trolley frame pedal car through fixed pulley, and the combination hanging basket steadily goes up and down with hoist rope.
Above-mentioned safety lock is equipped with insurance steel cable, and this insurance steel cable one end is connected with the inspection vehicle frame, and the other end is connected with safe counterweight.
The design's sectional hanging basket has outstanding features such as advanced design, operating efficiency is high, installation is simple, safe and reliable, and its technology and economic effect are fairly obvious.Implement in the maintenance and inspection process; Since about two hanging baskets through fixing above it two links form an integral body; The staff can safety on this total hanging basket work, and the space that the staff is positioned is bigger, inspection is also big with the space of safeguarding so; Can carry out continuous examination and maintenance comprehensively to bridge end face diagonal brace interconnecting part like this, accomplish upkeep operation satisfactoryly.

The specific embodiment
How combine accompanying drawing to further specify the utility model implements at present:
Two link covers about 2 are provided with, and corresponding upper and lower connection montant 2-1,2-2 and bracing diagonal 2-3 are arranged, and its upper and lower level frame respectively is provided with four trundles 4; Hanging basket 1 two ends have spacing bumper 5 and whippletree 5-2 respectively; Spacing bumper 5 is equipped with safety lock 5-1 (referring to Fig. 4,5); About two links overlap the outside that 2 correspondences are nested in two hanging baskets 1, move relative to hanging basket 1 left and right horizontal through trundle 4 up and down, when about two links overlap 2 relative hanging baskets and move to upper and lower connection montant 2-1,2-2 and bracing diagonal 2-3 corresponding matching in opposite directions and be connected; Again respectively with two of two links cover 2 connect montant 2-1,2-2 are fastenedly connected with junction plate 3; Two hanging baskets 1 are connected are integral hanging basket (referring to Fig. 7), the spacing bumper 5 of hanging basket guarantees that hanging basket is connected with the safety of link cover; Hoist rope 6 one ends are connected on the whippletree 5-2 after walking around safety lock 5-1, and the other end links to each other with bicycle 10 through the fixed pulley 9 on the inspection vehicle frame 11; Insurance steel cable 7 is connected with inspection vehicle frame 11 through an end behind the safety lock, and the other end is connected with safe counterweight.Therefore, through trampling bicycle 10 the combination hanging basket is steadily gone up and down thereupon, even the combination hanging basket rises track cable 6 unexpected disconnections, the spring assembly on the safety lock can be locked with insurance steel cable 7 immediately, guarantees that the hanging basket safety and stability is unlikely to drop.
During bridge field conduct inspection work,, control left and right sides hanging basket 1 drops to appointment from the cross bore of steel purlin bridge end face diagonal brace height respectively through stepping on the bicycle 10 on the inspection trolley 11; And guarantee left and right sides hanging basket 1 alignment relative, and brake bicycle 10 through locking device, make left and right sides hanging basket 1 keep motionless at the height of appointment; Every side hanging basket 1 has a maintainer; Every maintainer slowly moves corresponding link 2, makes both relative motions, after the butt joint of left and right sides link; The staff fixes left and right sides link 2 with connecting steel plate 3; Two hanging baskets 1 are connected are integral hanging basket, the maintainer may stand in the diagonal brace crossbar contact under check and safeguard that and the staff can be in the combination hanging basket in relatively large space implements inspection and safeguards bridge floor in a big way.
