And rainwater enters and influences operation.
In the device of the invention, since the distance that the energization cable of connection electrical equipment twists or twists together being capable of basis
The turnning circle of pivoted frame and step-by-step movement adjusts, therefore, when pivoted frame turnning circle is less, length that energization cable twists
Shorter, after pivoted frame rotates multi-turn, energization cable occurs kink position and moves closer to threading cam, thus can avoid energization cable
Kink starts to betide at the position of threading cam or certain specific location, excessively turns round to avoid result in local conducting wire
Transformation shape and lead to the damage of energization cable.Whole device is reliable for operation, can effectively solve the problem that problem of the prior art.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of building tower crane device of the invention；
Fig. 2 is the partial enlargement diagram of region of interest in Fig. 1；
[Fig. 3 is the structural schematic diagram of the threading cam in the present invention.
Specific embodiment
In conjunction with Fig. 1-3, a kind of building tower crane device of embodiment according to the present invention, including tower body 31, rotationally pacify
Mounted in 31 upper end of tower body pivoted frame 9 and be fixedly mounted on the pivoted arm 90 of the pivoted frame right end, 31 upper end of tower body is set
It is equipped with groove 32, threading cam 92 is fixedly installed in the middle part of 9 lower end of pivoted frame, is dividually worn with for more energization cables 93
Row, the threading cam 92 and two sliding bar 95 being fixedly connected be fixedly mounted in the tower body 31 and positioned at institute
5 rotary type of the elastic feeding part connection of 32 lower end of groove is stated, is slidably fitted on two sliding bars 95 and intersects rotating disc 8,
The more energization cables 93 from the pivoted frame 9 pass through the intersection rotating disc 8 after can intersect and with the elasticity
The energization column 59 fed on part 5 connects, and the more energization cables 93 are also penetrated into from pivoted frame 9 in pivoted arm and and electrical equipment
It connects, two works of the motion stops 53 and the motion stops 53 that are acted on by elastic component 51 is provided in the elastic feeding part 5
The elastic feeding part 5 is stretched out with bar 531 and is connect with 8 rotary type of rotating disc that intersects, wherein the threading cam 92
Two sides are symmetrically arranged two sliding racks 6 that can be horizontally slipped in the groove 32, and each sliding rack 6 is arranged
There are multiple classification teeth 61, the intersection rotating disc 8 is under the press of the motion stops 53 and is located at described two sliding racks 6
The lower end surface rotational engagement of two upper and opposite classification teeth 61,92 each rotation of threading cam can will be described two
The extruding of sliding rack 6 opens it is primary, on the intersection rotating disc 8 can be stepped up and is bonded under the press of the motion stops 53
Two opposite classification teeth 61 on described two sliding racks 6 so that the intersection rotating disc 8 and the elasticity into
Increase to 931 length of energization cable twist section between part 5；It is close that rotation is also equipped between the tower body 31 and the pivoted frame 9
Seal 99, the rotary seal circle 99 can prevent dust and rainwater from entering and influencing operation.
Illustratively or advantageously, wherein it is described intersect rotating disc 8 two sides be inclined-plane 88 to the classification tooth
61 bezel facet cooperation, in order to run up the step-by-step movement for intersecting rotating disc 8.
Illustratively or advantageously, wherein the movable chamber of the elastic feeding part 5 locating for the elastic component 51 only passes through
Through slot 52 and penetrated through with outside so that the motion stops 53 to run up speed adjustable.
Since the distance that the energization cable of connection electrical equipment twists or twists 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 energization cable twists is shorter, turns in pivoted frame
After dynamic multi-turn, energization cable occurs kink position and moves closer to threading cam, thus can avoid energization cable kinking and starts to send out
Be born in close to threading cam position at or certain specific location, to avoid result in local conducting wire excess torsional deflection and cause
The damage of energization cable.Whole device is reliable for operation, can effectively solve the problem that problem of the prior art.
In the process of running, the stepwise motion for intersecting rotating disc can either control the length of kink route, and can be right
Later route combing and orientation, so that it is guaranteed that close to pivoted frame direction line parallel stretch and avoid excessively wind or knot show
As occurring.
Whole device is reliable for operation, can effectively solve the problem that problem of the prior art.
Those skilled in the art can define, can in the case of not departing from overall spirit of the invention and design
To make the various modifications for above embodiments.It falls within the scope of protection of the present invention.Protection scheme of the invention
It is subject to claims appended hereto.
