Kink starts to betide the opening position or certain specific location close to threading cam, is excessively turned round so as to avoid result in local wire
Change shape and cause the damage of energization cable.Whole device is reliable, can effectively solve the problem that problem of the prior art.
Brief description of the drawings
Fig. 1 is a kind of structural representation of tower crane device for construction of the present invention；
Fig. 2 is the close-up schematic view of region of interest in Fig. 1；
Fig. 3 is the structural representation of the threading cam in the present invention.
Embodiment
With reference to Fig. 1-3, a kind of tower crane device for construction according to an embodiment of the invention, including tower body 31,
It is installed in rotation on the pivoted frame 9 of the upper end of tower body 31 and is fixedly mounted on the pivoted arm 90 of the pivoted frame right-hand member, the tower
The upper end of body 31 sets fluted 32, threading cam 92 is installed with the middle part of the lower end of pivoted frame 9, with for more energization cables
93 dividually walk, and the threading cam 92 is by two sliding bars 95 being fixedly connected and with being fixedly mounted on the tower body 31
In and the rotary type of elastic feeding part 5 positioned at the lower end of groove 32 connect, be slidably fitted with friendship on two sliding bars 95
Rotating disc 8 is pitched, the more energization cables 93 can intersect simultaneously after from the pivoted frame 9 through the intersection rotating disc 8
It is connected with the energization post 59 on the elastic feeding part 5, the more energization cables 93 also penetrate into pivoted arm simultaneously from pivoted frame 9
It is connected with electrical equipment, the motion stops 53 acted on by elastic component 51 and the motion stops is provided with the elastic feeding part 5
53 two actuating rods 531 stretch out the elastic feeding part 5 and are connected with the rotary type of rotating disc 8 that intersects, wherein, it is described to wear
The both sides of line cam 92 are respectively symmetrically provided with two travelling carriages 6 that can be horizontally slipped in the groove 32, each described
Travelling carriage 6 is provided with multiple classification teeth 61, the intersection rotating disc 8 under the top pressure of the motion stops 53 with respectively positioned at described
On two travelling carriages 6 and relative two classification tooth 61 lower surface rotational engagements, it is described threading each rotation energy of cam 92
Enough to open the extruding of described two travelling carriages 6 once, the intersection rotating disc 8 can walk upwards under the top pressure of the motion stops 53
Two for entering and being bonded on classification tooth 61 relative on described two travelling carriages 6, so that in the intersection rotating disc 8
The length of energization cable twist section 931 increase between the elastic feeding part 5；Between the tower body 31 and the pivoted frame 9 also
Rotary seal circle 99 is installed, the rotary seal circle 99 can prevent dust and rainwater from entering and influenceing operation；It is described two
The upper end of travelling carriage 6 and the inner end wall that contacts of threading cam 92 are provided with ball, the ball to the threading cam
92 outer end leans, smooth so as to rotate the threading cam 92.
Exemplarily or advantageously, wherein, it is described intersect rotating disc 8 two sides for inclined-plane 88 to the classification tooth
61 bezel facet cooperation, in order to run up the step-by-step movement of the intersection rotating disc 8.
Exemplarily or advantageously, wherein, the movable chamber of the elastic feeding part 5 residing for the elastic component 51 only passes through
Groove 52 and penetrated with outside so that the motion stops 53 to run up speed adjustable.
The distance that energization cable due to connecting electrical equipment twists or twisted together can be according to the turnning circle of pivoted frame
And step-by-step movement adjusts, therefore, when pivoted frame turnning circle is less, the length that its energization cable twists is shorter, turns in pivoted frame
After dynamic multi-turn, energization cable occurs kink position and moves closer to thread cam, and energization cable kinking thus can be avoided to start to send out
Opening position or certain specific location close to threading cam are born in, is caused so as to avoid result in local wire excess torsional deflection
The damage of energization cable.Whole device is reliable, can effectively solve the problem that problem of the prior art.
In the process of running, the length that the stepwise motion of rotating disc can either control kink circuit, enough pair of and can are intersected
Circuit combing afterwards and orientation, so that it is guaranteed that the line parallel close to pivoted frame direction is stretched and avoids showing for excessive winding or knotting
As occurring.
Whole device is reliable, can effectively solve the problem that problem of the prior art.
Those skilled in the art can be clear and definite, can in the case of the overall spirit of the present invention and design is not departed from
To make the various modifications for above example.It is each fallen within protection scope of the present invention.The protection scheme of the present invention
It is defined by claims appended hereto.
