Brief description of the drawings
Fig. 1 is the structure diagram of specific embodiment of the utility model one.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
The specific embodiment one of the shield cutter hoisting mechanism of the utility model, as shown in fig. 1, including tunnel gantry
Frame, ground hoisting mechanism 1, ground leading block 2, portal frame leading block 3, fixed pulley group 4, running block 5 and fag end are fixed
Device 6, portal frame leading block 3 are located at the end of tunnel portal frame, and fixed pulley group 4 is fixed on tunnel portal frame, movable pulley
The bottom of group 5 is equipped with suspension hook, the steel wire rope 11 of ground hoisting mechanism 1 pile warp ground leading block 2, portal frame leading block successively
3rd, fixed pulley group 4 and running block 5, the fag end of steel wire rope 11 are fixed on tunnel portal frame by rope head fixing device 6.
Hoisting mechanism 1 is arranged on ground, and the steel wire rope 11 of hoisting mechanism 1 is oriented to via ground leading block 2 and portal frame
After the conversion of 3 travel direction of pulley, tunnel portal frame is fixed on further around the fag end through fixed pulley group 4 and running block 5, steel wire rope 11
On, shield cutter is lifted by the suspension hook on running block 5, lifting is easy to operate, and hoisting mechanism 1 is located at ground and can keep away
Exempt to take tunnel portal frame headroom, and then also steel wire rope 11 can be avoided to wind, influence the normal lifting of shield cutter.
Ground hoisting mechanism 1 is located at shield tunnel bottom at tunnel wall, and it is empty can to avoid taking cutterhead installation in tunnel
Between.
Portal frame leading block 3 and ground leading block are correspondingly arranged about 2, then 11 pile warp portal frame of steel wire rope, which is oriented to, slides
Wheel 3 and ground leading block 2 are in 90 jiaos, and according to fixed pulley principle, rope traction power is smaller, meanwhile, steel wire rope 11 is along perpendicular
Nogata can also avoid taking cutterhead installation space in tunnel to setting.
Portal frame leading block 3 and fixed pulley group 4 it is highly consistent, then steel wire rope 11 is directed to fixed pulley in the horizontal direction
Group 4, it is ensured that the stability that steel wire rope 11 alters course, certainly, and in the other embodiment of the utility model, portal frame leading block
3 height vertically can be higher or lower than the height of fixed pulley group 4 vertically.
Fixed pulley group 4 is fixed on the center of tunnel portal frame, since shield cutter and shield tunnel are adapted, shield
Cutterhead center of gravity is consistent with the lifting of fixed pulley group 4 direction, and shield cutter raising is more steady, certainly, in other of the utility model
In embodiment, fixed pulley group 4 can be fixed on other suitable positions on tunnel portal frame.
Rope head fixing device 6 includes open type lock section, otic placode and axis pin, and the fag end of steel wire rope 11 sets open type to lock section, otic placode
It is fixed on tunnel portal frame, open type lock section is connected with otic placode by axis pin, is set using the above structure, steel wire rope 11 and tunnel
The fixed structure of portal frame is firm, and then steady lifting of the suspension hook that can ensure to set on running block 5 to shield cutter, when
So, in the other embodiment of the utility model, the fag end of steel wire rope 11 can be directly anchored on tunnel portal frame.
Rope head fixing device 6 is fixed on the center of tunnel portal frame, ground hoisting mechanism 1, ground leading block 2,
Portal frame leading block 3, fixed pulley group 4 and running block 5 are equipped with two and symmetrical on the center of tunnel portal frame
Set, then shield cutter is lifted by crane by two pulley block systems, lifting more stability and high efficiency.
The specific embodiment two of the shield cutter hoisting mechanism of the utility model, difference lies in ground with embodiment one for it
Face hoisting mechanism 1, ground leading block 2, portal frame leading block 3, fixed pulley group 4, running block 5 and rope head fixing device 6
It is single, only shield cutter is lifted by crane by single pulley block system, simplifies hoisting mechanism.
