Abstract
The utility model discloses an optical cable corner pulley which can prevent an optical cable from jumping out of a groove and being damaged during laying electric power communication cables. The optical cable corner pulley includes a suspension bracket, a wire wheel is sleeve at the middle of a rotating shaft of the suspension bracket, two rolling wheels are disposed at the positions corresponding to the circumference of the wire wheel, the rolling wheels are supported by two inclined rods, the other ends of the inclined rods are fixed on two ends of the rotating shaft, at outside of the suspension bracket, and edges of two ends of each of the rolling wheels are respectively provided with flanges corresponding to two end surfaces of the wire wheel. On the premise of ensuring the laying efficiency of optical cables, the optical cable corner pulley can prevent an optical cable from jumping out of a groove and being damaged, and risks can be prevented when a worker works high above the ground.
Description
Technical field
The utility model relates to a kind of cable laying utility appliance, particularly a kind of for power communication cable laying coaster.
Background technology
At present, development along with economy and city, the construction of power cable and transformation project are more and more, the safety and stability of and electrical network safe and efficient in order to ensure cable construction, the general optical cable pulley that adopts in cable laying, can alleviate difficulty of construction and intensity like this, but all there is the problem of job-hoping in optical cable distraction procedure in existing optical cable pulley, not only the optical cable after job-hopping is difficult to process, and the identification information of erasing on cable jacket, serious meeting damages cable core, thereby has caused the increase of cost and the decline of work efficiency.
Summary of the invention
The utility model technical issues that need to address are to provide a kind of assurance under the prerequisite of fiber cable laying efficiency, prevent optical cable job-hopping and the corner optical cable pulley of effectively protecting optical cable not to be damaged.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A corner optical cable pulley, comprises suspension bracket, and the intermediate sleeve of the rotating shaft of this suspension bracket is equipped with line wheel, and the position of the circumference of taking turns at corresponding line arranges roller, and roller supports by two braces, and the other end of brace is sleeved on the outside of the two ends of rotating shaft, suspension bracket.
Further improvement of the utility model is: roller is provided with two, lays respectively at suspension bracket both sides.
Further improvement of the utility model is: roller is to be arranged between two braces by screw rod; Screw rod is through in the hole of two brace outer ends, and uses respectively two fastening nuts; On the screw rod of roller both sides, also arrange a pair of for making the nut that roller is corresponding with the crossed beam trunking of line wheel.
Owing to having adopted technique scheme, the obtained technical progress of the utility model is:
Corner optical cable pulley of the present utility model is guaranteeing under the prerequisite of fiber cable laying efficiency, prevents optical cable job-hopping and effectively protects optical cable not to be damaged, and has so not only avoided the risk of high-rise working, and has reduced construction cost.
Between two groups of brace ends of corner optical cable pulley, be provided with roller, can make like this roller push down optical cable in line race, during unwrapping wire, can touch roller during optical cable bob, roller band moving-wire wheel rotates, and effectively like this prevents optical cable job-hopping.When not using, folding rack can be drawn close to suspension bracket, so that collection in use, can be adjusted the angle that folding rack opens according to the size of electric wire corner, to adapt to setting up of different corner optical cables.
The flange that the edges at two ends of roller arranges respectively, encases for line is taken turns to cylindrical, and place optical cable in line race and jump out from the gap of line wheel and roller, even coaster is used for to angle position, can the de-groove of optical cable yet.Roller is through on screw rod, and with nut location, can adjust arbitrarily the crossed beam trunking position that the relative line of roller is taken turns, roller and screw rod cross-under, and fix by nut and brace, conveniently take off roller optical cable is installed.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details:
A corner optical cable pulley, comprises line wheel 2 and suspension bracket 3, and line wheel 2 is arranged on the centre of suspension bracket 3 by rotating shaft 6.The upper end of this suspension bracket 3 is provided with suspension rod 12 by latch 10, and when latch 10 is extracted, suspension rod 12 can be opened.Hook 7 is equipped with by bearing pin 11 in the middle part of suspension rod 12.On the position of the circumference of corresponding line wheel 2, two rollers 4 are set, the edges at two ends of roller 4 is respectively arranged with flange, and flange is corresponding with the both ends of the surface of line wheel 2, makes roller 4 be stuck in line and takes turns on 2 cylindrical.Each roller 4 supports by two braces 5 respectively, and the other end of brace 5 is sleeved on the two ends of rotating shaft 6, the outside of suspension bracket 3.Brace 5 is sleeved in rotating shaft 6 and can 6 rotates around the shaft.At two braces 5 that are positioned at line and take turns 2 the same sides, also by a connecting piece 8, connect, by the location, position of two rollers 4, as shown in Figure 1, 2, brace 8 is by coupling bolt 9 bracing diagonals 5.
During work, cable is penetrated to built-in line wheel 2, brace 5 can rotate and can adjust around the rotating shaft 6 of suspension bracket 3 arbitrarily angled, and brace 8 is by the angle orientation of two rollers, and the line that makes roller 4 compress coaster is taken turns the optical cable in 2.During unwrapping wire, can touch roller 2 during optical cable bob, thereby stop the optical cable roller groove that comes off.
