Specific embodiment
Core technology thought of the invention is that the constraint of cross-arm rising trace is realized by T-shaped guide rail, when lifting rope
Fracture or when installing by cam with T-shaped guide rail inverted running when friction realize the locking of cross-arm position.
With reference to Fig. 4 and Fig. 5, the first embodiment of the present invention is described in detail below.
A kind of steel tube tower cross-arm installs equipment, including hoisting mechanism and anti-falling mechanism, and anti-falling mechanism includes master
Body 1, has in main body 1 and cam 2 is installed in cam mounting groove 28, pinhole of camshaft 29 and pulley mounting groove 30, cam mounting groove 28,
Cam 2 has two through holes, and axis 8 is inserted into pinhole of camshaft 29 and connects cam 2 and cam mounting groove 28 through a through hole,
Another through hole is connected through steel wire rope with the cross-arm 13 for being lifted;Trailing wheel 3 and front-wheel 5, trailing wheel 3 are installed in pulley mounting groove 30
Fixed by pulley pin with front-wheel 5;There is dovetail groove 10 in main body 1.
Further, pinhole of camshaft constitutes gap and coordinates with axis.
Further, trailing wheel and front-wheel are fixed on body by pulley pin, and the pulley pin constitutes interference fit with body.
Further, insertion before and after dovetail groove in main body.
Further, wheel face is fitted in T-shaped rail after the diameter dimension of trailing wheel and front-wheel should ensure that installation during fabrication
On road.
With reference to Fig. 6 and Fig. 7, the second embodiment of the present invention is described in detail below.
Front-wheel 5 is installed, front-wheel 5 is fixed by pinch roller pin 7 in main body 1, torsion spring 9 is installed on pinch roller pin 7.
Further, the resilient both sides of torsion spring tool are separately fixed in main body dovetail groove on upper groove surface the medial surface with pinch roller
On, torsion spring center passes through axis.
Further, during cross-arm rises, cam remains the state for upwarping.
Further, then cam should be loaded so that torsion spring in the dovetail conduit first by torsion spring as main body during installation
Side is stuck in dovetail groove upper surface, and side is withstood on cam, then passes through axis, so under the elastic force effect of torsion spring, cam
Remain the state for upwarping.
With reference to Fig. 1, Fig. 2 and Fig. 3, the third embodiment of the present invention is described in detail below.
Hoisting mechanism includes T-shaped guide rail 14, and T-shaped guide rail 14 is fixed on tower body 31, tower body 31 by angle steel fixed seat
Top is bolted the first reverse wheel 20 and the second reverse wheel 21, and the first reverse wheel 20 and the second reverse wheel 21 can be around
Commutation wheel shaft 19 is rotated.
Further, T-shaped track is to be spliced, and is provided with splicing hole on the track of stitching portion, adjacent track by connecting plate and
Bolt is fixed.
The installation site of T-shaped guide rail 14 is located at the underface of cross-arm seat 11, and the first fall arrest is respectively mounted on two side rails
17 and second fall arrest 24.
Further, there is support arm mounting hole in the first fall arrest and the second fall arrest main body.
Hoisting mechanism include elevator motor 15, the output shaft elevator line wheel 16 of elevator motor 15, elevator line wheel 16 passes through
Support is fixed on concrete pedestal, the lay winding wire ropes 18 of elevator line wheel 16, and steel wire rope bypasses the first reverse wheel 20 and the second commutation
Wheel 21 is connected in the second fall arrest 24.
Second fall arrest 24 is bolted installation support arm 25, and installation support arm 25 is round steel, there is hanger 26 on round steel, is weighed
Profit requires that 1 cross-arm 13 is realized hanging by hanger.
Further, only steel wire rope, the falling proof device of the non-scope of operation is passed through not to use on the falling proof device of the scope of operation.
Further, fluted on elevator wheel, the steel wire rope for folding and unfolding is stored in groove.
For the first reverse wheel 20 and the second reverse wheel 21, when steel tube tower dispatches from the factory, the top of tower body has been welded on.
When cross-arm installation is carried out, the output shaft elevator line wheel 16 of elevator motor 15 is bolted on cement base first
On plinth, steel wire rope is pulled out from elevator line wheel 16 by workmen then, bypass the first reverse wheel 20 and second at the top of tower body
Reverse wheel 21, then steel wire rope is put down, by ground construction personnel by the second fall arrest cam on steel wire penetrating mounting surface
Threading hole.
Now, ground staff is installed in the second fall arrest 24 by bolt by support arm 25 is installed first, then by hanging
Be mounted to cross-arm 13 on installation support arm 25 by ear 26.
Finally, elevator motor 15 is started, under the drive of motor, installing support arm 25 can rise with cross-arm 13, until fortune
Can be installed together for cross-arm 13 and cross-arm seat 11 by cross-arm mounting hole 27 now to the position of cross-arm seat 11 by row.
The operation mechanism of anti-falling mechanism is, is not stressed when cam 2 or during stress very little, in the twisting force of torsion spring 9
Under, anti-falling mechanism can be stuck on T-shaped track and remain stationary as, after carry cross-arm, anti-falling mechanism is applied on T-shaped guide rail
Downward active force it is very big, because cam 2 is a kind of ellipsoidal structure, can be rotated during stress so that oval longitudinal end card
Tight downward stress is bigger on T-shaped track, and it is more firm that anti-falling mechanism mechanism locks, it is ensured that cross-arm 13 is to cross-arm
When seat 1 is installed, the reliability of punching, it is also possible to prevent the danger fallen during workmen's operation.
To sum up, present disclosure is not limited in the above embodiments, and those skilled in the art can be in the present invention
Guiding theory within propose other embodiments, but these embodiments are included within the scope of the present invention.
