Abstract
The utility model discloses a spiral shaft capable of being dismounted rapidly in a tunnel. The spiral shaft is characterized by comprising a plurality of segments of spiral shaft units, and the spiral shaft units are connected through connecting keys. The spiral shaft capable of being dismounted rapidly in the tunnel is characterized in that an existing spiral shaft which is welded integrally is changed into a plurality of spiral shaft units, and connecting positions of the spiral shaft units are connected by the connecting keys. The specific number of the spiral shaft units is relative to a shield internal structure and a mounting space. The spiral shaft units can be sectionally dismounted on the connecting positions when the spiral shaft is dismounted, and the spiral shaft units also can be mounted sectionally in the tunnel, so that a spiral conveyer can be mounted and dismounted conveniently in a narrow space.
Description
Technical field
The utility model belongs to helical axis, be specifically related to a kind of can be in the tunnel helical axis of quickly dismantled.
Background technology
Conveying worm is the important component part of earth pressure balanced shield, EPBS, it is mainly constructed by shown in Figure 1, is comprised of cylindric casing 3 and helical axis 1, and casing 3 front flange ends are connected with shield body 2 by bolt, the rear portion is provided with screw machine muck removal door 6, and helical axis 1 is driven by screw machine drive unit 5.Existing helical axis 1 is welded by columned axle and helical blade, and it carries out the assembly and disassembly of conveying worm as a global facility.When earth pressure balanced shield, EPBS during at underground driving, under special circumstances need to be in the tunnel conveying worm be dismantled and the work such as assembled.Yet be subjected to the in-built spatial constraints of shield machine structure and peace tunnel, conveying worm has the angle of inclination about 23 degree when installing, when hanging out backward, conveying worm must reduce tail height, because the screw machine afterbody is rear supporting crane span structure, conveying worm reduces height will inevitably interfere with the rear crane span structure, and this just brings a lot of difficulties to dismantlement work.
The utility model content
The purpose of this utility model provide a kind of can be in the tunnel helical axis of quickly dismantled, to solve dismounting in the existing one-piece auger screw alley, hard problem be installed.
The technical solution adopted in the utility model is: can be in the tunnel helical axis of quickly dismantled, comprise some sections helical axis unit, adopt connecting key to connect between the described helical axis unit.
Described connecting key is the spline connecting key, formed by connecting pin, outer connecting key, interior connecting key, spacer pin, wherein inside and outside connecting key, the link with the helical axis unit welds together respectively, fix by connecting pin after the inside and outside connecting key assembling engagement, simultaneously mounting limit pin on connecting pin.
Described connecting key is internal-external hexagon formula connecting key, formed by interior hexagonal connecting key, bolt, baffle plate, outer-hexagonal connecting key, connecting pin, two interior hexagonal connecting keys weld together with the link of helical axis unit respectively, fix by connecting pin after two interior hexagonal connecting keys and outer even hexagonal connect key assembling engagement, connect baffle plate in the connecting pin end with the bolt installation simultaneously.
Characteristics of the present utility model are to change the existing helical axis that is welded into integral body into some sections helical axis unit, the connection of junction employing connecting key.Concrete unit number is relevant with shield structure internal construction and installing space.Can be with the helical axis unit in the dismounting of linkage section punishment section during the dismounting helical axis; Equally in the tunnel also sectional the helical axis unit is installed, thereby realize conveying worm comparatively easily dismounting in small space.
Below in conjunction with drawings and Examples the utility model is described further.

Among the figure: 1. helical axis, 2. shield body, 3. screw machine cylinder-like shell, 4. tunnel duct piece, 5. screw machine drive unit, 6. screw machine muck removal door, 7. connecting key, 701. connecting pins, 702. outer connecting keys, 703. interior connecting key, 704. spacer pins, 705. interior hexagonal connecting keys, 706. bolt, 707. baffle plate, 708. outer-hexagonal connecting keys, 709. connecting pins.
The specific embodiment
Referring to Fig. 2, can be in the tunnel helical axis 1 of quickly dismantled, comprise 3 sections helical axis unit 101,102,103, all adopt connecting key 7 to connect between the helical axis unit 101,102 and between the helical axis unit 102,103, the quantity of helical axis unit can be determined according to condition of construction.
First helical axis unit 102,103 two sections junction are taken apart in when dismounting, take off 103 sections of helical axis unit; Then helical axis unit 101,102 two sections junctions are taken apart, take out in order helical axis unit 102,101 sections.In like manner in when assembling, load onto first helical axis unit 101,102 two sections, then 103 sections of helical axis unit are loaded onto.
Connecting key 7 has two kinds of forms: spline and internal-external hexagon formula.
The spline connecting key as shown in Figure 3, formed by connecting pin 701, outer connecting key 702, interior connecting key 703, spacer pin 704, wherein inside and outside connecting key 703,702 welds together with helical axis unit 101,102 links respectively, fixing by connecting pin 701 after inside and outside connecting key 703, the 702 assembling engagements, mounting limit pin 704 on connecting pin 701 prevents that connecting pin 701 from coming off simultaneously.Dismounting helical axis unit 101,102 o'clock is extracted spacer pin 704 first, connecting pin 701 is split out again, and then interior connecting key 703 is extracted from outer connecting key 702.
Internal-external hexagon formula connecting key as shown in Figure 4, formed by interior hexagonal connecting key 705, bolt 706, baffle plate 707, outer-hexagonal connecting key 708, connecting pin 709, two interior hexagonal connecting keys 705 weld together with helical axis unit 101,102 links respectively, a pin-and-hole is arranged on the interior hexagonal connecting key 705, respectively there is a pin-and-hole at two ends on the outer-hexagonal connecting key 708, after connecing key 708 assembling engagements with outer even hexagonal, fix by connecting pin 709 two interior hexagonal connecting keys 705, for preventing that connecting pin 709 from coming off, with bolt 706 connection baffle plate 707 is installed in connecting pin 709 ends.During 101,102 sections of dismounting helical axis unit, first bolt 706 is turned on, pulled down baffle plate 707, take off again connecting pin 709, then interior hexagonal connecting key 705 and outer-hexagonal connecting key 708 are separated.
