Same appended drawing reference indicates.
Referring to figs. 1 to shown in Fig. 3, a kind of connection component for inspection shaft anti-drop net of the present embodiment includes positioning
Part 1, mounting ring 2 and several Suo Sheng mechanisms 3 offer the location hole 11 passed through for swell fixture on locating piece 1, by locating piece
1 and mounting ring 2 be integrally formed, it is ensured that the bonding strength between locating piece 1 and mounting ring 2, what locating piece 1 and mounting ring 2 were formed
Entirety can understand the change of recurring structure because being installed on the different position of inspection shaft, as shown in figure 1, when 1 He of locating piece
When mounting ring 2 is integrally located at the well head of inspection shaft, mounting ring 2 is in circle ring column, and locating piece 1 is in circular ring plate, and location hole 11 is fixed
On the end face of position part 1, locating piece 1 and mounting ring 2 are coaxially disposed and are sheathed on outside mounting ring 2, well of 1 frame of locating piece in inspection shaft
Mouth end face, mounting ring 2 protrude into inspection shaft, and swell fixture is passed through location hole 11 and squeezes into ground, complete installation；Referring in particular to
Shown in Fig. 2, when locating piece 1 and mounting ring 2 is whole be respectively positioned in inspection shaft when, locating piece 1 is in central column, and location hole 11 is located at fixed
On the peripheral wall of position part 1, mounting ring 2 is also in central column, and mounting ring 2 and locating piece 1 are coaxially disposed, and the outer wall of locating piece 1 fits in
On the borehole wall of inspection shaft, swell fixture is passed through into location hole 11 and is squeezed into the borehole wall, completes installation, two ways is according to actual conditions
Depending on；Location hole 11 can be designed to counter sink, then after swell fixture completes installation, the nut will not relative positioning part 1 it is prominent
Out, can so protect swell fixture to be hardly damaged will not bump to people, and the peace of well lid can also be conducive to for first way
Dress；
Several Suo Sheng mechanisms 3 include that gag lever post 31, shaft 32 and the rope frame 33 in bending, gag lever post 31 are close
In the well head of inspection shaft, frame 33 of restricting is folded upward at, and several shafts 32 have been rotatably connected on the end face of mounting ring 2, several
Root shaft 32 is respectively positioned on same circumference, and several shafts 32 are coaxially arranged with driving wheel 4, several driving wheels 4 engage
In on same transmission item 5, driving wheel 4 and transmission item 5 may respectively be gear and rack gear or sprocket wheel and chain, according to practical feelings
Depending on condition；One end of gag lever post 31 is connected in shaft 32, and rope 33 one end of frame is connected in mounting ring 2, the other end and gag lever post
31 is inconsistent, in design installation process, mounting ring 2 is cut into upper cover and holding shell along its cross-wise direction, rope frame 33 connects
In on the shell wall of holding shell, holding shell offers accommodating chamber, offers the axis hole passed through for shaft 32 in upper cover and holding shell,
One end by shaft 32 far from gag lever post 31 penetrates in holding shell outside holding shell, and driving wheel 4 is passed through from shaft 32 and is accommodated
One end of shell is connected in shaft 32, then driving wheel 4 and shaft 32 remain opposing stationary, and driving wheel 4 is located at accommodating chamber
It is interior, transmission item 5 is engaged on several driving wheels 4 simultaneously, finally upper cover is covered on holding shell, so to driving wheel 4
It is protected with transmission item 5, avoids outside contamination, conducive to extending driving wheel 4 and being driven the service life of item 5；In original state
Under, a closed annular is collectively formed in gag lever post 31, shaft 32 and rope frame 33, when needing that anti-drop net is placed in inspection shaft
When, it will wherein a shaft 32 rotate, and transmission item 5 be driven by driving wheel 4, then other driving wheels 4 rotate, accordingly
Shaft 32 rotate, then several gag lever posts 31 are separated with corresponding rope frame 33, and anti-drop net can be sheathed on to rope frame at this time
On 33, then shaft 32 reversed, gag lever post 31 is again inconsistent with rope frame 33, and anti-drop net is connected to the part on rope frame 33 at this time
It is limited, being designed in this way can prevent anti-drop net from washing away in rainwater compared with the prior art lower easily falls off from hook；When anti-fall
When needing to replace in time after net aging, it is designed in this way and needs compared to existing middle maintenance personal to the anti-drop net interconnecting piece at hook
Position is split and is installed one by one, and the used time is short, easy to operate, high-efficient.
As a kind of improved specific embodiment, referring to figs. 1 to shown in Fig. 2, rope frame 33 includes connecting rod 34 and set
Rope bar 35, one end of connecting rod 34 is positioned in mounting ring 2 and the extending direction of connecting rod 34 is parallel with the end face of mounting ring 2,
The other end is connected with one end of noose bar 35, and connecting rod 34 and noose bar 35 are integrally formed, noose bar 35 not with 34 phase of connecting rod
One end even offsets with gag lever post 31, and the connecting portion of anti-drop net is sheathed on noose bar 35, noose bar 35 and 34 liang of connecting rod
The case where angle between person is non-acute angle, is designed in this way compared to the angle of noose bar 35 and connecting rod 34 between the two when being acute angle,
Anti-drop net need to can only be mentioned upwards it is not necessary that anti-drop net gets off from the fractionation on noose bar 35 one by one when dismantling anti-drop net
It rises, the part that anti-drop net is sheathed on several noose bars 35 is moved along the extending direction of noose bar 35 and divided with noose bar 35
From further improving the removal efficiency of anti-drop net.
It, in conjunction with first embodiment, can be clamped as a kind of improved specific embodiment referring to figs. 1 to shown in Fig. 3
After good driving wheel 4, it is clamped the snap ring with limited block 37 again in shaft 32, both limited block 37 and shaft 32 remain
It is opposing stationary, and the limiting slot 38 mobile for limited block 37 is offered on end face of the upper cover towards holding shell, to upper cover and hold
After shell phase of receiving connects, limited block 37 is located in limiting slot 38, and during rotating shaft 32, limited block 37 is in limiting slot 38
Interior movement is designed in this way the inconsistent angle model to limit the rotation of shaft 32 of both ends cell wall by limited block 37 and limiting slot 38
It encloses, conducive to the positioning of gag lever post 31, avoids the opposite rope frame 33 of gag lever post 31 from turning over head, reduce the difficulty that gag lever post 31 positions.
As a kind of improved specific embodiment, referring to figs. 1 to shown in Fig. 3, for being moist environment in inspection shaft,
It is be easy to cause the satiny and relatively fine shaft phenomenon of the change of shaft 32, is coaxially arranged on one in several shafts 32
For the knob 36 of people's force, it is designed in this way personnel easy to repair and finds the good point of application, it is more laborsaving, improve dismounting anti-drop net
Efficiency.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
