Abstract
A kind of large-tonnage bridge floor crane anchoring rod system, including rear anchor tie, the upper end of anchor tie is after adjusting nut is fixed on anchor beam after described, the lower end of anchor tie is connect with anchoring ear mount afterwards, the anchoring ear mount lower end, which sells axis connection, anchoring pulling plate, anchors the anchoring otic placode on the lower end connection girder steel of pulling plate.The present invention is connected using " bolt type ", is connected between rear anchor beam and anchoring ear mount by rear anchor tie, and fixed using adjustable nut, the feature for having pull rod stress clear, safe and reliable.
Description
Technical field
The present invention relates to a kind of large-tonnage bridge floor crane anchoring rod systems.
Background technique
Bridge floor erecting crane is bridge erection special construction equipment, and the anchor of erecting crane is that crane is important
Component part provides sufficient anchor force for crane, it is ensured that card complete machine safety and stability.As China's bridge floor erecting crane is specified
Lifting capacity is increasing, and the rear anchor pulling force of crane is also just increasing, then the design requirement to anchor is also more next
It is higher.
Under normal conditions the anchoring rod of anchor with anchoring ear mount using being threadedly coupled, and be casting process and
At.But as bridge floor crane anchoring pulling force is increasing, anchoring ear mount size is increasing, and manufacturing cost also constantly adds
Greatly, and it is dangerous.
Summary of the invention
Its purpose of the invention, which is that, provides a kind of large-tonnage bridge floor crane anchoring rod system, solves with bridge
Crane anchoring pulling force in face is increasing, and anchoring ear mount size requirements are increasing, and there are manufacturing costs also to continue to increase, and not
The problem of safety.
It adopts the technical scheme that achieve the above object, a kind of large-tonnage bridge floor crane anchoring rod system,
Including rear anchor tie, it is described after anchor tie upper end after adjusting nut is fixed on anchor beam, the lower end of rear anchor tie and anchoring
Ear mount connection, the anchoring ear mount lower end, which sells axis connection, anchoring pulling plate, anchors the anchoring on the lower end connection girder steel of pulling plate
Otic placode.
Beneficial effect
The present invention has the following advantages that compared with prior art.
It is an advantage of the invention that being connected using " bolt type ", connected between rear anchor beam and anchoring ear mount by rear anchor tie,
And fixed using adjustable nut, have pull rod stress clear, manufacturing cost is low, and safe and reliable advantage.
Detailed description of the invention
The invention will be further described with reference to the accompanying drawing.
Fig. 1 is schematic structural view of the invention；
Fig. 2 is structure of the invention side view；
Fig. 3 is the structural schematic diagram of rear anchor tie in the present invention；
Fig. 4 is the structural schematic diagram that ear mount is anchored in the present invention；
Fig. 5 is the structural side view that ear mount is anchored in the present invention.
Specific embodiment
This system includes rear anchor tie 2, and as Figure 1-Figure 5, the upper end of the rear anchor tie 2 is fixed through adjusting nut 1
On rear anchor beam 5, the lower end of rear anchor tie 2 is connect with anchoring ear mount 3, and 3 lower end of anchoring ear mount is connected with anchoring through pin shaft 6
Pulling plate 4, the lower end of anchoring pulling plate 4 connect the anchoring otic placode 7 on girder steel 8.
The upper end of anchor tie 2 is equipped with helicitic texture 21 corresponding with adjusting nut 1, the lower end of rear anchor tie 2 after described
It is fixed with end-blocking plate 22, the lower end of rear anchor tie 2 is fixedly connected in anchoring ear mount 3 through end-blocking plate 22.
In the present invention, the rear anchor tie 2 is penetrated in the mounting hole of anchoring ear mount 3, the end-blocking plate 22 of rear 2 lower end of anchor tie
It fixes in the mounting hole of anchoring ear mount 3, the upper end of rear anchor tie 2 is mounted on rear anchor beam 5 by adjusting nut 1, anchors ear
The lower end of seat 3 is anchored at 7 on the anchoring otic placode of girder steel 8 by anchoring pulling plate 4, so that enough anchoring pulling force are provided for complete machine,
Anchor counter-force is drawn by rear anchor after crane, and 2 are transferred in anchoring ear mount 3, is reached on girder steel 8, is adjusted finally by anchoring pulling plate 4
Spiral shell, 1 can carry out small range adjustment according to live actual height, to adapt to live height error.
The present invention in the specific implementation, uses six sets of dresses on a certain rated load weight 1800t erecting crane
It sets, the anchoring of side purlin is arranged four sets altogether, and every two sets are arranged symmetrically, and middle purlin is arranged two sets, and anchor support reaction is very big after the crane, is
More than ten times or even tens times of the anchoring support reaction of general crane, the anchoring rod stress is clear, securely and reliably, and uses effect
Fruit is very good.
