Description
Technical field
The utility model is related to the suspender detachers in lifting device more particularly to a kind of steel column hoisting process.
Background technology
With China's rapid development of economy, capital construction is maked rapid progress.In a collection of large span, extensive workshop, exhibitions
The engineering constructions such as the heart, stadiums, high level and Super High are risen.The steel structure member of these engineerings is not only again but also high.Traditional people
The method of steel column decoupling device seems simple above and below work climbing cat ladder, but there are the following problems for practical operation：When after steel column is in place,
Worker needs to climb to capital from ground, manually takes rigging, there is safety during steel column and excision rigging above and below worker
Risk, this process is time-consuming longer, influences project progress；Second is that because of steel column above and below personnel, the side of steel column must be provided with elongated
Cat ladder, the fixation of cat ladder and steel column welded, this form inevitably injures base material；Third, in an engineering item
In mesh, every layer of every steel column is required for setting cat ladder, and material and the labour cost for making cat ladder are larger, and cat ladder is simultaneously after engineering
It cannot reuse, cause to waste.
Utility model content
The utility model be to avoid the deficiency present in the above-mentioned prior art, providing a kind of sling for steel column detacher, with
Automatically-unhooked mode avoids the process of personnel's cat ladder, so as to ensure safety, avoid waste of material, speed up the work.
The utility model is adopted the following technical scheme that solve technical problem：
The utility model sling for steel column detacher is structurally characterized in that：The suspender uses " u "-shaped snap ring, at " U "
Side plate through-hole is respectively arranged on the both side plate of shape snap ring, it is " T " shape on the side plate outer wall of the " u "-shaped snap ring to be welded one
Duan Gangguan, the other end of steel pipe are closed by end plate, and open up end plate through-hole, the end plate through-hole and " u "-shaped card in end plate central
The side plate through-hole and steel tube inner hole of ring are mutually communicated and are on coaxial position；
Axis pin runs through steel pipe, and forms spring latch structure, under the action of spring catch, the front end of axis pin with steel pipe and end plate
It can be maintained in the side plate through-hole on the both side plate of " u "-shaped snap ring, steel column lifting lug is enable to hang on axis pin；In axis pin
Tail end connects extended drag-line using draw ring, pulls drag-line that axis pin can be made to exit " u "-shaped snap ring, and steel column lifting lug is made to break off relations.
The design feature of the utility model sling for steel column detacher is lain also in：The spring latch structure refers to by steel pipe and end
Plate forms spring base, and on axis pin, the plate washer fixation of spring at front end is welded on axis pin the spring pocket in spring base, utilizes pressure
The spring of dress forms axis pin the pretightning force towards " u "-shaped snap ring side.
Compared with the prior art, the utility model has the beneficial effect that：
The utility model by the way that drag-line is pulled to realize the automatically-unhooked of steel column lifting lug, complete on the ground, keeps away by operating process
Exempt from the process of personnel's cat ladder, effective guarantee construction safety, while also avoid waste of material, speed up the work.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model；
Figure label：1 be " u "-shaped snap ring, 2 steel pipes, 3 springs, 4 axis pins, 5 plate washers, 6 draw rings, 7 end plates, 8 drag-lines,
Specific embodiment
Referring to Fig. 1, the structure type of sling for steel column detacher is in the present embodiment：Suspender uses " u "-shaped snap ring, at " U "
Side plate through-hole is respectively arranged on the both side plate of shape snap ring, it is " T " shape on the side plate outer wall of " u "-shaped snap ring 1 to be welded one section
Steel pipe 2, the other end of steel pipe 2 are closed by end plate 7, and open up end plate through-hole, end plate through-hole and " u "-shaped snap ring 1 in end plate central
Side plate through-hole and the endoporus of steel pipe 2 be mutually communicated and be on coaxial position.
Axis pin 4 runs through steel pipe 2, and forms spring latch structure, under the action of spring catch, axis pin 4 with steel pipe 2 and end plate 7
Front end can be maintained in the side plate through-hole on the both side plate of " u "-shaped snap ring, steel column lifting lug is enable to hang on axis pin；
The tail end of axis pin 4 connects extended drag-line 8 using draw ring 6, pulls drag-line 8 that axis pin 4 can be made to exit " u "-shaped snap ring, makes steel column
Lifting lug breaks off relations.
In specific implementation, spring catch structure type is：Spring base is formed by steel pipe 2 and end plate 7, the spring 3 in spring base
It is sleeved on axis pin 4, the fixation of plate washer 5 of 3 front end of spring is welded on axis pin 4, and court is formed to axis pin 4 using the spring 3 of press fitting
To the pretightning force of " u "-shaped snap ring side；Rope 9 shown in Fig. 1 is used to carry out auxiliary operation to detacher during lifting.
Operating process：
1st, the steel column for treating handling is placed in advance in the region with lifting, it is ensured that steel column lifting lug is solid and reliable；Loop wheel machine is pressed
It is in place according to specified position.
2nd, drag-line is pulled, and axis pin is driven to be detached from " u "-shaped snap ring by drag-line, makes the opening-like state of " u "-shaped snap ring；By steel column
Lifting lug is placed in " u "-shaped snap ring, unclamps drag-line, and the axis pin of rebound runs through the earhole of steel column lifting lug and " u "-shaped snap ring two jointly
Side plate through-hole on side plate realizes the hook of steel column lifting lug, implements lifting.
3rd, after steel column lifting is in place, ground staff pulls drag-line, axis pin is driven to be detached from " u "-shaped snap ring by drag-line again,
Make the opening-like state of " u "-shaped snap ring, realize the unhook of steel column lifting lug.
