A kind of special hanger for concrete tubular pile lifting
This utility model belongs to suspender field, particularly a kind of special hanger for concrete tubular pile lifting.
Conventional concrete pile tube is carrying out storing in a warehouse, during transporting and hoisting, l type or c type metal suspender are usually used, mixed
Solidifying soil pile tube carries out storing in a warehouse, transporting and hoisting operation when often occur that the security risk of stake is fallen in unhook, and also can often occur
The extruding of metal suspender causes surface concrete to damage, affects the situation of pile tube quality and outward appearance, and this problem never obtains very
Good solution, therefore, in the urgent need to a kind of new special hanger using when lifting for concrete tubular pile.
Utility model content
The purpose of this utility model is to provide a kind of overall construction design ingenious, easy to operate it is ensured that Hoisting Security, and
And ensure that concrete tubular pile outward appearance, the impregnable special hanger of quality in hoisting process.
The technical solution realizing this utility model purpose is:
A kind of special hanger for concrete tubular pile lifting, including pressure hook, hook, described pressure hook one end is provided with pressure hook folder
Hold end, the pressure hook other end is provided with lifting hole, the pressure hook between pressure hook bare terminal end and lifting hole is provided with stopper slot, described support
Hook includes montant, cross bar, and montant upper end is connected with the stopper slot of pressure hook by axle, and montant lower end is fixedly connected with cross bar one end,
The cross bar other end is provided with hook bare terminal end.
Preferably, described pressure hook bare terminal end 11 and hook bare terminal end 23 are all provided with rubber sleeve.
Preferably, between described montant 21 and cross bar 22, angle is 90 °.
Preferably, described pressure hook bare terminal end 11 length is more than hook bare terminal end 23 length.
This utility model compared with prior art, its remarkable advantage:
(1) this utility model is used for the special hanger whole technical scheme reasonable in design of concrete tubular pile lifting, skilful
Wonderful, easy to operate, high working efficiency, convenient disassembly；
(2) special hanger that this utility model lifts for concrete tubular pile increased rubber sleeve and is used for protecting inside and outside pile tube
Concrete reduce the impact to quality and outward appearance for the lifting, simultaneously take account of the wall thickness of pile tube, accordingly increased angle and
Spacing design, reduces the excessive quality impact on concrete tubular pile in lifting operation of lifting clamping force；
(3) this utility model is used for the hook of special hanger of concrete tubular pile lifting and pressure hook relies on spacing formation certain
The angle close to pile tube wall thickness, pressure hook bare terminal end slightly longer hook bare terminal end simultaneously, during clamping, pressure hook is longer than hook part and supports
Live outside concrete tubular pile, form larger angle because hook hangs naturally, only need to touch pressure hook external arc and partly so lift by crane again,
(4) special hanger that this utility model lifts for concrete tubular pile is provided with lifting hole and u-shaped card can be used directly
Suspender or the connection of other forms, in installation and bridge crane, gantry crane or autocrane, easy to use.
(5) this utility model is simple for the special hanger design of concrete tubular pile lifting, handling ease, service life
Long, job safety is secure, is particularly well-suited to concrete tubular pile storage, the lifting operation of transport.
The special hanger that below in conjunction with the accompanying drawings this utility model is used for concrete tubular pile lifting is described in further detail.
Fig. 1 is the special hanger overall structure diagram for concrete tubular pile lifting；
Fig. 2 is the special hanger top view for concrete tubular pile lifting；
Fig. 3 is the special hanger side view for concrete tubular pile lifting；
Fig. 4 is the special hanger lifting pile tube schematic diagram for concrete tubular pile lifting.
As Figure 1-4:
A kind of special hanger for concrete tubular pile lifting, including pressure hook 1, hook 2, described pressure hook 1 one end is provided with pressure
Hook bare terminal end 11, pressure hook 1 other end is provided with lifting hole 12, and the pressure hook 1 between pressure hook bare terminal end 11 and lifting hole 12 sets
Limited location groove 13, described hook 2 includes montant 21, cross bar 22, and montant 21 upper end is connected with the stopper slot 13 of pressure hook 1 by axle,
Montant 21 lower end is fixedly connected with cross bar 22 one end, and cross bar 22 other end is provided with hook bare terminal end 23；Stopper slot 13 is provided with limit
Position 131, for ensureing the restriction of the suspender self falling kinetic energy when lifting completes so that removing suspender conveniently, safely, the same to time limit
Position 131 also ensures that has certain angle when carrying out suspender lifting concrete tubular pile 3, is unlikely to Slip Hook in lifting；Spacing
Groove 13 is provided with spacing 131, for ensureing the state in the clamping force meeting or slightly larger than concrete tubular pile 3 lifting for the special hanger
Under no longer have extra clamping force, it is to avoid because suspender clamping force crosses macrolesion concrete tubular pile 3；For concrete tubular pile lifting
When lifting completes concrete tubular pile 3 and lands, hook 2 is also hung special hanger naturally, returns to spacing 131 position, no
External force is needed to unclamp suspender, simple to operation.
Described pressure hook bare terminal end 11 and hook bare terminal end 23 all cover rubber sleeve, for protecting concrete tubular pile 3 in lifting
During reduce damage.
Between described montant 21 and cross bar 22, angle is 90 °, for ensure concrete tubular pile 3 lifting when be vertically subject to as far as possible
Power, plays stress, lifting active force reasonably acts on, it is to avoid crane or other crane gears accept a little unreasonable damage
Crane and the problem of other suspenders.
Described pressure hook bare terminal end 11 length is more than hook bare terminal end 23 length, for being pressure hook when concrete tubular pile lifts by crane
1 extension is pressed on the outer wall of concrete tubular pile 3 end face, hook 2 state now for naturally hanging, simultaneously because of spacing 131
Constraint shape at a certain angle, the circular arc afterbody at this moment touching pressure hook 1 can guarantee that hook 2 gos deep into concrete tubular pile 3 inwall,
Lifting lifting is convenient and simple.
The operation principle of the special hanger for concrete tubular pile lifting for the utility model:
By be used for concrete tubular pile lifting special hanger be connected with suspender belt, chain sling or steel wire rope 4, manually buttress suspender belt,
Chain sling or steel wire rope 4, with the mobile special hanger of suspender belt, chain sling or steel wire rope 4 near concrete tubular pile 3, by pressure hook 1 elongated portion
Partial pressure lives the outer wall of concrete tubular pile 3 end face, the artificial outside acting on pressure hook 1 using strength of one's legs, will be used for concrete tubular pile and hang
In special hanger propulsion concrete tubular pile 3 end face of dress, now hook 2 has been enter in the hole in concrete tubular pile 3, has commanded and has reseted
Standby lifting, notices that sling height is unlikely to unhook for formation clamping force and is advisable, the lifting now as completing, using above-mentioned
Identical process is lifted by crane to concrete tubular pile 3 another one end face, after the completion of as complete the lifting of concrete tubular pile 3
Front mounting hanger work, now can carry out lifting mobile operation.
After relying on crane gear lifting concrete tubular pile 3 to land, using manually pulling open suspender belt, chain sling or steel wire rope 3 it is
Can, unclamp the special hanger for concrete tubular pile lifting without external force.
To sum up complete whole actions that concrete tubular pile 3 lifts by crane, stacks.
