Abstract
The utility model discloses a special lifting lug for a shield machine lifting, which is capable of being fast installed and repeatedly used. The special lifting lug comprises a main lifting ear plate, a reinforcing plate and a bottom plate, wherein a through hole used for connecting a high-intensity screw bolt group is drilled on the bottom plate, the main lifting lug plate, the reinforcing plate and the bottom plate are welded by steel plates, and the through hole arranged on the bottom plate corresponds to a through hole arranged on a case of a shield machine. During the lifting, the bottom plate of the lifting lug is connected with the shield machine through the high-intensity screw bolt group, the lifting lug is disassembled after the assembly of the shield machine is completed, a sealing pin shaft with a waterproof sealing ring firmly plugs a bolt hole arranged on the case of the shield mechanism, and the lifting lug can be repeatedly used.
Description
Technical field
The utility model relates to a kind of novel hanger that can lift on-the-spot Fast Installation at shield machine.
Background technology
Domestic all shield machines comprise from the shield machine of external import and all adopt the welded type hanger that installation as shown in Figure 1, the stiffener (2) of main shackle plate (3) and both sides thereof directly is welded on the shield machine shell (6) at present.The welded type hanger in use has many inconveniences.At first, location and welding are inconvenient.Shield machine belongs to greatly, jumbo, and the single-piece quality is mostly about 100 tons.Accurately location and welding hanger difficulty on its surface require highly to welder's level, field condition is poor, welding quality be difficult to control and the welding job amount very big.Secondly, also need hanger excision and polishing is clean after each shield machine is gone into the well and installed, the hanger after the excision is owing to impaired being difficult to repeatedly uses.At last, repeatedly on the shield machine shell, weld and cut hanger and make the shield machine case surface impaired easily, the solderability variation of material, mechanical strength reduces, and influences structural performance.
Summary of the invention
In order to solve the problem that the welded type hanger exists in construction, the utility model provides a kind of shield machine to lift special-purpose hanger, and not only installation and removal are convenient in construction for this special-purpose hanger, and can reuse.
The technical scheme that its technical problem that solves the utility model adopts is: the welded type hanger that will use at present makes hanger detachable, that connect with the high-strength bolt group into.The main shackle plate of hanger is welded on the base plate, and two face down bondings of main shackle plate connect stiffener, is processed with the hole that connects usefulness for bolt on base plate.The corresponding hole of line processing on the relevant position of shield structure housing is fixed on hanger on the housing with high-strength bolt in addition.Hanger adopts steel plate processing by professional factory, and steady quality is reliable.In construction, just can carry out lifting operation after the high-strength bolt group installed.The shield structure is gone into the well and after assembling is finished hanger is pulled down, and with special bearing pin the hole of the installation high-strength bolt on the shield structure housing is sealed.
The beneficial effects of the utility model: hanger can be installed at the construction field (site) rapidly and accurately, and low to site operation personnel's level requirement, hanger and shield machine attachment security are reliable, and hanger can be reused, to shield machine shell not damaged.
Practice explanation with the shield machine dismounting: line on shield structure housing, location and welding hanger, need 5 experienced operators at every turn, just can finish in 4 days.And adopting detachable hanger, 2 common laborers just can finish in 1 day.Cutting welded type hanger needs 2 experienced operators just can finish in 2 days at every turn on shield structure housing.Use detachable hanger, 2 common laborers can finish in 1 day.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a welded type hanger schematic diagram.
Fig. 2 is the front view of novel hanger.
Fig. 3 is the lateral view of novel hanger.
Fig. 4 is the vertical view of novel hanger.
Fig. 5 is a shield machine lifting operating mode front view.
Fig. 6 is a shield machine lifting operating mode lateral view.
Fig. 7 is the A-A sectional view of Fig. 6.
Fig. 8 is the seal approach of shield machine shell behind the dismounting hanger.
Among the figure: 1. base, 2. stiffener, 3. main shackle plate, 4. high-strength bolt group, 5. shear resisting board, 6. shield machine shell, 7. waterproof grommet, 8. sealing bearing pin.
The specific embodiment
In Fig. 2, the bottom of main shackle plate (3) is welded on the upper surface of base (1), and the direction of main shackle plate is consistent with the pull of steel wire direction.The both sides of main shackle plate (3) respectively are welded with a stiffener (2), and the bottom of stiffener (2) is welded on the upper surface of base (1), as shown in Figure 3.Be drilled with the hole of using on the base (1), as shown in Figure 4 for the high-strength bolt group.Novel hanger adopts steel plate machine-shaping by professional factory, and it is reliable and stable to ensure the quality of products.
In Fig. 5 and Fig. 6, shield machine adopts 2 liftings when lifting.The installation site of novel hanger on shield machine as shown in Figure 5.In Fig. 7, use high-strength bolt group (4) that the base (1) of hanger is linked together with shield machine shell (6), just can carry out lifting construction then.Be welded on shear resisting board (5) on the shield machine shell horizontal component when bearing lifting, make the high-strength bolt group be in tension state fully.In Fig. 8, after the shield machine assembling is finished, remove bolt group (4) and just can take off hanger, the bolt hole on the shield machine shell (6) uses the stifled jail of the sealing bearing pin (8) that has waterproof grommet (7), satisfies the requirement that shield machine shell (6) seals in constructing tunnel.Hanger can be reused.
Existing 6 shield machines of my unit have carried out the hanger transformation to 4, and since 2006, above-mentioned 4 shield machines have been finished lifting construction tens of times.Facts have proved that the utility model mode of occupation is fine, lot of manpower and material resources has been saved in Fast Installation and dismounting at the construction field (site), has created considerable economic.
Claims (2)
1. a shield machine lifts special-purpose hanger, this hanger is made up of main shackle plate, stiffener and base plate, main shackle plate is consistent with the lineoutofservice signal pull direction, it is characterized in that: have on hanger base plate and the shield machine shell and somely be connected the holes of usefulness for the bolt groups, base plate links together by high-strength bolt group and shield machine shell.
2. shield machine according to claim 1 lifts special-purpose hanger, it is characterized in that: described base plate, main shackle plate and stiffener are made by the steel plate welding.
