End.
Specific use process is as follows for above-mentioned twisted and released of the cable line support frame: first by above-mentioned two twisted and released of the cable line branch
Support is staggered relatively, and cable drum is placed between two twisted and released of the cable line support frames, is received by two cables of rotation
Load-bearing steel plate height on two twisted and released of the cable line support frames is adjusted unanimously, then will by the nut on unwrapping wire support frame
After cable drum is sleeved on the outside of cable axis, the both ends of cable axis are inserted into frame supported on both sides respectively on load-bearing steel plate corresponding
Mounting hole in, cable drum is mounted on two twisted and released of the cable line support frames, two cables is then rotated synchronously and receives
Nut on unwrapping wire support frame steadily lifts cable drum, and cable drum can be freely rotated along cable axis at this time, and scene is applied
Worker person can drag cable and carry out the work of twisted and released of the cable line.
The twisted and released of the cable line is mainly welded by channel steel and steel plate with support frame, makes, the cable low with maintenance cost
Retractable cable is small with support frame occupied area, and transhipment is convenient, is suitable for that construction site space is limited or execution conditions rugged environment,
After the support frame, the construction speed of cable laying is not only increased, and ensures cable in the construction ring of inclement condition
It when being laid under border, is not damaged, it is ensured that construction quality, increased costs caused by avoiding due to cable bad.At the same time,
The twisted and released of the cable line support frame is simple to operate, and the speed for mounting and dismounting cable drum is fast, and cable laying can be improved
Construction speed effectively reduces hanging device when furthermore carrying out the construction of twisted and released of the cable line with support frame using the twisted and released of the cable line
Utilization rate, it can be achieved that construction cost reduction.
In order to ensure the stability and safety of the twisted and released of the cable line support frame, can be supported in above-mentioned twisted and released of the cable line
Cone bearing 8 is added in frame, referring to Fig. 1, Fig. 2, Fig. 3, which is set in screw rod 5 between nut 7 and steel plate 4
Outside.By the way that cone bearing is arranged, it may make nut rotation more steady, so as to when lifting cable drum, two cables
Nut on retractable cable support frame rotates synchronously, it is ensured that the center of gravity of cable drum does not shift, and then avoids due to electricity
Cable reel centre-of gravity shift run-off the straight is toppled over, and working security is further improved.
Referring to fig. 4, a base construction for twisted and released of the cable line support frame, the pedestal are devised in the present embodiment
1 is T-shaped, is mainly made of transverse bar 11 and two vertical bars 12, and two vertical bars 12 are parallel to each other, and is respectively positioned on transverse bar
11 it is ipsilateral, corresponded respectively with the position of the first column channel steel 2 and the second column channel steel 3, and the one of two vertical bars 12
End is fixedly connected with transverse bar 11.The T-type structure of said base designs, and is ensuring that twisted and released of the cable line support frame operation is steady
While qualitative, reduce the self weight of the twisted and released of the cable line support frame, so as to be suitable for construction site space it is limited or construction
The environment of inclement condition.
In order to further increase the structural stability of the twisted and released of the cable line support frame, referring to Fig. 1, also set up in pedestal 1
Have the first bearing diagonal 13 and the second bearing diagonal 14, wherein 13 one end of the first bearing diagonal is fixedly welded with transverse bar 11, the other end with
First column channel steel 2 is fixedly welded, and 14 one end of the second bearing diagonal is fixedly welded with transverse bar 11, the other end and the second column channel steel
3 are fixedly welded.By the setting of above-mentioned first, second bearing diagonal, the knot of the twisted and released of the cable line support frame can be effectively improved
Structure stability and bearing capacity, and then ensure the safety of construction, avoid the generation of safety accident.
In order to further improve the structural stability of the twisted and released of the cable line support frame, referring to fig. 2, Fig. 3, in pedestal 1
In be additionally provided with third bearing diagonal 15 and the 4th bearing diagonal 16, wherein 15 one end of third bearing diagonal and the first column channel steel 2 are solid
Fixed welding, other end vertical bar 12 corresponding with the first column channel steel 2 are fixedly welded, 16 one end of the 4th bearing diagonal and the second column
Channel steel 3 is fixedly welded, and other end vertical bar 12 corresponding with the second column channel steel 3 is fixedly welded.
Due to, needing to use in the construction process various types of cables, due to the model of cable and the difference of weight, electricity
The size and axis hole of cable reel are also not quite similar, and for the ease of mounting and dismounting cable drum, the cable in the present embodiment is received
Unwrapping wire is gradually decreaseed from top to bottom with load-bearing steel plate 6 in support frame along the aperture of the spaced mounting hole 61 of short transverse.It is logical
It crosses and is provided with the different mounting hole of pore size, can be selected corresponding according to the cable drum actual conditions of different model
Mounting hole carries out the installation of cable drum, while improving twisted and released of the cable line support frame work operation stability, also improves
The replacement speed of cable drum, and then construction speed is improved, work efficiency is high.
Since the weight of cable drum is big, operator needs firmly to rotate the spiral shell on twisted and released of the cable line support frame top
Mother can lift cable drum, in order to facilitate the operation of personnel's rotating nut, while reduce the working strength of operator, this reality
The side for applying nut 7 in the twisted and released of the cable line support frame in example circumferentially spaced is provided with multiple push rods 71.Operator is logical
Crossing promotion push rod rotates nut, reduces the working strength of operator, and then improves work efficiency.
