Abstract
The invention discloses a special lifting appliance for shield segment three-ring horizontal assembling. The lifting appliance comprises a rectangular lifting plate, circular bead design is adopted at the joints of the upper long side and the short sides of two sides of the lifting plate, two lifting lugs are welded to each of the two long sides of the lifting plate, circular holes are formed in the lifting lugs, and three lifting holes are formed in the positions, close to circular beads, of each of the two ends of the short sides of the lifting plate. In the segment three-ring horizontal assembling process, the lifting appliance can finely adjust the positions of segments, guarantee the segment assembling precision, quickly finish assembling and improve the construction efficiency; and moreover, in the lifting process, four-point lifting is adopted, lifting is stable, the segment breakage phenomenon can be reduced, and construction safety is guaranteed.
Description
Technical field
The present invention relates to a kind of shield duct piece suspender technical field, particularly relate to a kind of shield duct piece three ring level and spell
Dress special hanger.
Background technology
Along with the development of city track traffic engineering, increasing city, the whole nation starts to develop the underground space, builds
If subway tunnel, subway tunnel shield construct owing to being safely, quickly widely used, shield prefabricated pipe
Sheet has waited until unprecedented development the most therewith, during the Prefabrication of shield duct piece, needs through the demoulding, hangs
The processes such as fortune, stacking and three ring level assembly tests, and need various suspender to carry out back work during it,
But in three ring level assembly tests of section of jurisdiction, existing suspender has two kinds, one be fixture type, one be straight
After connecing employing curved bolt reeve bolt hole, nut of screwing on lifts.
Two kinds of lifting modes are all difficult to ensure the fine of pipe sheet assembling position during the ring level assembly of section of jurisdiction three
Adjusting, the corner angle easily causing section of jurisdiction are damaged, and there is potential safety hazard in hoisting process.
Summary of the invention
Present invention seek to address that the deficiencies in the prior art, provide a kind of special hanger for section of jurisdiction three ring level assembly,
After three ring hydraulic tests of section of jurisdiction require assembled cyclization, internal-and external diameter and vertical, circumferential weld precision prescribed are increased, and use this
Invention suspender can effectively ensure the intense adjustment of pipe sheet assembling position during the ring level assembly of section of jurisdiction three, has
Effect reduces the breakage rate of section of jurisdiction, ensures construction safety.
The present invention for achieving the above object, by the following technical solutions: a kind of shield duct piece three ring level is assembled specially
With suspender, it is characterised in that include boatswain chair, boatswain chair is rectangle, the upper long edges of boatswain chair and both sides minor face
Junction uses fillet design, two long limits of boatswain chair is respectively welded two hangers, is provided with circle inside hanger
Hole, the minor face two ends of boatswain chair have three lifting hole(eyelet)s at fillet.
As preferably, described boatswain chair, hanger are steel plate.
As preferably, a diameter of 30mm of described circular hole.
The invention has the beneficial effects as follows:
(1), ensure pipe sheet assembling position intense adjustment, improve efficiency of construction: suspender of the present invention is in section of jurisdiction
During three ring level assembly, trickle position, adjustment section of jurisdiction can be carried out, it is ensured that pipe sheet assembling precision, can be quick
Assembly completes, and improves efficiency of construction.
(2), segment damage phenomenon is reduced, it is ensured that construction safety: the present invention, in hoisting process, uses four
Point lifting, lifting is stable, it is possible to reduce segment damage phenomenon, it is ensured that construction safety.
Accompanying drawing explanation
Fig. 1 is the top view of the present invention.
Fig. 2 is the front view of the present invention.
Fig. 3 is the lifting schematic diagram of the present invention.
Shown by reference numeral: 1 boatswain chair, 2 lifting hole(eyelet)s, 3 hangers, 4 shackles, 5 steel wire ropes, 6 curved bolts,
7 suspension hooks, 8-section of jurisdiction.
It is described in detail referring to the drawings below with reference to embodiments of the invention.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described:
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of shield duct piece three ring level assembly special hanger, including using
20mm steel plate makes the boatswain chair 1 of a length of 2000mm, wide 200mm, and boatswain chair 1 is rectangle, boatswain chair 1
Upper long edges uses fillet design with the junction of both sides minor face, and two long limits of boatswain chair 1 are respectively welded two
Individual hanger 3, hanger 3 uses 20mm steel plate to make, the internal circular hole being provided with a diameter of 30mm of hanger 3,
The minor face two ends of boatswain chair 1 have three lifting hole(eyelet)s 2, a diameter of 30mm of lifting hole(eyelet) 2, two ends at fillet
Lifting hole(eyelet) 2 correspondence spacing two-by-two is 1742.856mm (section of jurisdiction 8 left-hand seat hole horizontal projection pitch).
The use of a kind of shield duct piece three ring level assembly special hanger of the present invention is first by four shackles 4 even
Being connected to the steel wire rope 5 that four hangers 3 use with lifting, steel wire rope 5 is hung on suspension hook 7, then by the present invention
Suspender winches on institute's swing pipe sheet 8, adjusts the lifting hole(eyelet) 2 using suspender according to section of jurisdiction 8 model, uses curved bolt 6
Wearing to section of jurisdiction 8 hand hole from the lifting hole(eyelet) 2 of boatswain chair 1, tightened by curved bolt 6 nut, section of jurisdiction 8 of slinging carries out assembly.
Above the present invention is exemplarily described, it is clear that the present invention implements and do not limited by aforesaid way
System, as long as have employed method design and the various improvement that carry out of technical scheme of the present invention, or the most improved directly
It is applied to other occasion, all within protection scope of the present invention.
