Abstract
The utility model discloses an installation and lifting device for a PGW optical cable accessory. A connection seat is fixed at the center of the bottom of a triangular lever. The left and right angles of the triangular lever are respectively provided with a suspension loop in a fixed manner. The upper part of the pedestal is fixedly connected with the connection seat through a bolt, thereby enabling the triangular to rotate around the bolt. The right side surface of the lower part of the pedestal is provided with a lateral groove which faces to the left side. A fastening bolt vertically passes through the bottom surface of the pedestal, and can be screwed to the interior of the lateral groove, or the bottom surface of the pedestal is provided with a vertical groove upwards, and the fastening bolt horizontally passes through the right side surface of the pedestal and can be screwed into the vertical groove. The device provided by the utility model solves a quality problem caused by two times of chain backing operations, effectively improves the work efficiency, simplifies the process flow of the optical cable accessory, and saves the cost of manpower.
Description
Technical field
The utility model relates to OPGW optical cable construction device in a kind of transmission line.
Background technology
In recent years; transmission line sets up middle ADSS optical cable and is progressively substituted by OPGW Optical Fiber composite overhead Ground Wire (hereinafter referred to as OPGW optical cable); because this type optical cable is combined with ground wire; the annex installment work of OPGW optical cable is in ground wire cross-arm position; have following installation question: (1) OPGW optical cable is the same with ADSS optical cable, need to use double-deck preformed armor rods protection hanging point, preformed armor rods conflicts with releasing pulley position while installation; cannot carry out disposablely laying completely, need to change and carry out secondary after suspension centre and lay.(2) because suspension centre jack cannot be suspended to preformed armor rods outside, extract after releasing pulley, need two jacks alternately lift optical cable, change hoisting point position, cause loaded down with trivial details and time of annex operation to increase, workload is large.(3) secondary change of hoisting point position, causes preformed armor rods center and hanging point centre deviation, and installation quality cannot ensure.(4) design of the ground configurations of different turriforms is different, and optical cable hanging point distance is shorter, uses jack hanging wire difficulty, and off-line accident easily occurs.
Summary of the invention
The problems referred to above that exist for solving prior art, the utility model provides a kind of PGW optical cable annex that lifting device is installed, and its technical scheme adopting is:
Comprise base, Connection Block and culdy, Connection Block is fixed on centre position, the bottom place of culdy, the two ends, left and right of culdy are fixed with respectively link, the top of base is fixedly connected with Connection Block by bolt, culdy can be rotated around bolt, the lower right side of base has translot left, fastening bolt vertically passes and can be screwed in translot from base end face, or base end face upwards has vertical slot, fastening bolt passes and can be screwed in vertical slot from the right flank level of base.
The utility model utilizes lever operation principle to promote optical cable, adopt and use culdy to set up ground wire ace, one end jack, the straight hook in one end, rotates and upgrades optical cable by tightening up jack lever, middle laying optical cable preformed armor rods and wire clamp, solve twice jack alternately operating and brought quality problems, effectively improve operating efficiency, simplified optical cable annex process flow, saved personnel cost.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1, Connection Block 2 is fixed on centre position, the bottom place of culdy 3, and the two ends, left and right of culdy 3 are fixed with respectively link 4, and the top of base 1 is fixedly connected with Connection Block 2 by bolt 5, and culdy 3 can be rotated around bolt 5.The lower right side of base 1 has translot left, fastening bolt 6 from base 1 bottom surface vertical through and can be screwed in translot, or base 1 bottom surface upwards has vertical slot, fastening bolt 6 from the right flank level of base 1 through and can be screwed in vertical slot.
When PGW optical cable annex is installed, first facade angle bar is stuck in translot, clamp this device by screwing fastening bolt 6, on the link 4 that is positioned at left side, straight shank hanging hook is installed, on the link 4 on right side, lever hoist is installed, is then used straight shank hanging hook to catch on a sidelight cable, make culdy 3 produce rotation torque by tightening up lever hoist, drive suspension hook side to rise, thereby make optical cable Integral lifting.
