Embodiment in the present invention, those of ordinary skill in the art's every other embodiment obtained belong to what the present invention protected
Range.
Embodiment
It is a kind of truss bridge piece purlin provided in an embodiment of the present invention turnover hoisting suspender referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4,
As shown in Figure 1, Figure 2, Figure 3, Figure 4, which includes at least two groups lifting lug group, at least two groups lifting lug group for respectively with piece purlin 7
On at least two groups hoist cable otic placode group be connected correspondingly；The hoist cable otic placode is installation and the permanent ear on 7 crossbeam of piece purlin
Plate, hoist cable otic placode are arranged in pairs.When being specifically chosen lifting lug quantity again, it can be selected according to the property and size of piece purlin
It selects, specifically, the lifting lug group number that at least two groups lifting lug group includes is plural number.It, can be with by the way of plural groups lifting lug group
Rear piece purlin uniform force is sling in guarantee, and then guarantees that piece purlin can be in plummet state.Make turn and hoisting process piece purlin simultaneously
Stability it is more preferable, be conducive to carry out general assembly construction.
Every group of lifting lug group includes two lifting lugs 1, and two respective one end of lifting lug 1 are connected by rope tool 3；Every group of hoist cable otic placode group
Including two hoist cable otic placodes 2；
Wherein, each lifting lug 1 is detachably connected with each hoist cable otic placode 2 correspondingly respectively.Specifically connecting
When lifting lug 1 and hoist cable otic placode 2, the lifting lug 1 passes through the ear on connector and the hoist cable otic placode 2 with the hoist cable otic placode 2
Plate hole realizes detachable be connected.Lug plate holes therein are the through-hole that hoist cable otic placode carries.Specifically, the lifting lug 1 may include
Two pieces of parallel risers 101, two pieces of risers 101 are connected by connecting plate 102；It is formed with and is used between two pieces of risers 101
The space that the hoist cable otic placode 2 is inserted into；Two pieces of risers 101 offer opposite through-hole；The connector sequentially passes through it
In the through-hole of a riser, lug plate holes and another riser through-hole.Further, the connector includes pin shaft 4, the pin shaft 4
On be provided with external thread section；The external thread section is used to be cooperatively connected with nut 5, to realize the lifting lug 1 and the hoist cable ear
The fastening of plate 2.In such a way that pin shaft 4 and nut 5 are cooperatively connected, it is ensured that lifting lug when being connect with otic placode, installation and
Disassembly is convenient.
Further, every group of lifting lug group has a suspension centre, and the suspension centre is located at the rope and has 3 length direction midpoints
Place.The rope tool 3 is wirerope.The set-up mode and suspension centre set-up mode of rope tool provided by the embodiments of the present application, Ke Yibao
Card piece purlin after the completion of turn is in plummet state.Have the advantages that simultaneously convenient and fast connection with suspender.
The embodiment of the present application can also provide a kind of application method of truss bridge piece purlin turnover hoisting suspender, such as scheme
Shown in 8, which comprises
The rope tool that at least two groups lifting lug group respectively contains is connected at least two suspenders 6 one-to-one correspondence respectively；
In the specific implementation, lifting lug is gone to be attached it by pin shaft and nut with one of hoist cable otic placode first, then again
The hoist cable otic placode opposite with mounted hoist cable otic placode is attached with another lifting lug by same mode, it will after connection
Rope tool is connected with two lifting lug tops.Other lifting lug groups are attached in the same way.
As shown in Figure 5, Figure 6, at least two suspenders 6 are promoted simultaneously, described purlin 7 is switched into plummet by horizontality
State, to realize the turn of described purlin 7.Specifically, the suspender is connected with boom hoisting, at least two suspender and same
One boom hoisting is connected.The boom hoisting can be driving.When it is implemented, two suspenders can be promoted for the major-minor of driving
Suspender.Boom hoisting, which continues to lift up for be moved at general assembly station the piece purlin, after completion is turned over can be completed lifting process.
It is described in detail for comprising lifting lug group described in four groups below:
Suspender provided by the present application can design four groups of suspenders using the hoist cable otic placode design feature of truss-type bridges, and every group is hung
Tool contains lifting lug, pin shaft and nut, and lifting lug is fixed in hoist cable lug plate holes with pin shaft and nut, and two sets of suspenders are a suspension centre,
Each lifting lug connects with rope tool respectively, and each pair of wirerope connects a suspension centre (suspension hook), when assembly finishes piece truss in the plane
When carrying out assembly assembly, mounting hanger completes turn and hoisting process, piece truss is lifted into assembly assembly position.The application
The lifting lug of offer is different from provides the mode of hanger in the prior art, as shown in fig. 7, the hanger provided in the prior art, usually
It is connected simultaneously with two hoist cable otic placodes for a hanger by pivot pin of growing up, in order to guarantee the intensity of hanger, the axis of growing up of production
Heavier-weight is sold, when installation usually requires grow up using lifting appliance auxiliary lifting pivot pin and hanger, and grow up one people of pivot pin
It is usually unable to complete installation, needs several workers to cooperate and completes installment work, several worker's cooperations are equally also required in disassembly
It could complete disassembly.It can be seen that the hanger provided in the prior art for piece purlin turns over the course of work, cumbersome difficulty of construction is big.And this
Apply for that the lifting lug provided is individually small in size, by the way of being used cooperatively in groups, both can satisfy lifting with proof strength and want
It asks, while can guarantee uniform force after lifting again.Lifting lug is individually light-weight, be not necessarily to lifting appliance auxiliary lifting lifting lug, one
The installation and dismantlement work of lifting lug can be completed in worker.The suspender will not generate injury to piece purlin itself simultaneously.
In short, truss bridge piece provided by the present application purlin turnover hoisting suspender, simple and reasonable, do not have in piece purlin base material
Upper welding is detachably connected using pivot pin with hoist cable otic placode, can be injury-free with effective protection base material.The suspender monomer mass
Gently, it is assisted without external force, it is easy for assemble or unload, it is suitble to any truss bridge piece truss to turn over and lift, worth large area pushes away
It is wide to use.
