Kink starts to betide at the position of threading cam or certain specific location, 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, the tower crane device for construction a kind of 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 and is installed with threading cam 92 in the middle part of fluted 32, the lower end of pivoted frame 9, with for many 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
Rotation dish 8 is pitched, many energization cables 93 can intersect simultaneously after from the pivoted frame 9 through the intersection rotation dish 8
It is connected with the energization post 59 on the elastic feeding part 5, many energization cables 93 are also penetrated into pivoted arm simultaneously from pivoted frame 9
It is connected with electrical equipment, the motion stops 53 and the motion stops acted on by elastic component 51 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 rotation dish 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 rotation dish 8 under the top pressure of the motion stops 53 be located at respectively it is described
On two travelling carriages 6 and relative two classifications tooth 61 lower surface rotational engagement, each rotation energy of threading cam 92
Enough to open the extruding of described two travelling carriages 6 once, the intersection rotation dish 8 can be walked 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 rotation dish 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 is provided with ball with the inner end wall that the threading cam 92 is contacted, and the ball is used to and the threading cam
92 outer end leans, so as to make the threading cam 92 rotate smooth.
Exemplarily or advantageously, wherein, it is described intersect rotation dish 8 two sides for inclined-plane 88 be used to and the classification tooth
61 bezel facet cooperation, in order to run up the step-by-step movement of the intersection rotation dish 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 with outside insertion so that the motion stops 53 to run up speed adjustable.
Because the energization cable distance that twists or twist together for connecting electrical equipment can be according to the rotation number of turns of pivoted frame
And step-by-step movement is adjusted, therefore, when the pivoted frame rotation number of turns 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 threading cam, and energization cable kinking thus can be avoided to start to send out
It is born at the position close to threading cam or certain specific location, so as to avoid result in the excessive torsional deflection of local wire and cause
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 of kink circuit can either be controlled by intersecting the stepwise motion of rotation dish, again can be right
Circuit afterwards is combed and oriented, so that it is guaranteed that the line parallel close to pivoted frame direction is stretched and avoids what is excessively wound or knot from showing
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.
