Lowering or hoisting gear drives the oscilaltion of pressing tongs fixture, is arranged on the horizontal travelling carriage;
The pressing tongs fixture is used for fixing pressing tongs, links to each other with lowering or hoisting gear.
The beneficial effect of the utility model: during use, be placed on two cables that need to connect and compress in the anchor ear, through the anchor ear seat can drive cable along anchor ear axially (being that cable is axial) move.Pressing tongs is contained on the pressing tongs fixture.Horizontal travelling carriage can drive pressing tongs and on axial perpendicular to cable, slide, and lowering or hoisting gear can drive pressing tongs.Like this, just can easily pressing tongs be moved to the cable junction, cable is carried out crimping.Use this platform that cable is connected, cable conveniently moving not only, pressing tongs move also convenient, have improved operating efficiency.Simultaneously, after construction is accomplished, horizontal travelling carriage; Lowering or hoisting gear, parts such as pressing tongs fixture take off from stake body, only stay anchor ear, anchor ear seat; And be fixed on the anchor ear seat on the stake body, then this product right side becomes the needed support platform of heavy in section single-core cable extended immobilization.
Above-mentioned support, pressing tongs fixture comprise a crushing clamper base, are extended with two gudgeons at the two ends of crushing clamper base; Two gudgeon along continuous straight runs extend, and are the symmetry axis symmetry with the axis of crushing clamper base; Lowering or hoisting gear is vertical two oil cylinders placing, and two gudgeons rotate and are arranged on the piston rod of two oil cylinders.Because crushing clamper base can be around the rotational of two gudgeons, like this, pressing tongs is promptly rotatable, to change the direction of exerting pressure of pressing tongs to cable.
Above-mentioned support, it also comprises bracing frame and horizontal travelling carriage, bracing frame be parallel to anchor ear axially on be slidingly arranged on the stake body; Laterally travelling carriage perpendicular to anchor ear axially on be slidingly arranged on the bracing frame.Like this, pressing tongs can be realized under the drive of bracing frame along the axial move left and right of anchor ear, and is convenient during use.
Above-mentioned support, anchor ear is made up of two hoops that link to each other with bolt.
Description of drawings
Fig. 1 is the schematic perspective view of the utility model.
Among the figure, stake body 1, slide rail 2, vertically move plate 3, channel-section steel 4, slide rail 5, bracing frame 6, gudgeon 7, laterally travelling carriage 8, anchor ear seat 9, anchor ear 10, hoop 11, channel-section steel 12, oil cylinder 13, bearing 14, pressing tongs fixture 15, crushing clamper base 16.
Embodiment
Referring to the platform that is used to connect the 220kv high-tension cable (support) shown in Fig. 1-3, comprise stake body 1, four anchor ears 10, anchor ear seat 9, laterally travelling carriage 8, pressing tongs fixture 15, two oil cylinders 13 (lowering or hoisting gear), bracing frame 6.Stake body 1, bracing frame 6, laterally travelling carriage 8, pressing tongs fixture 15, two oil cylinders 13 (lowering or hoisting gear) etc. have been formed the pressing tongs carriage.
Stake body 1 mainly comprises two channel-section steels 4.Each anchor ear 10 is made up of two hoops 11 that link to each other with bolt up and down.Following hoop 11 is fixed on the anchor ear seat 9.Per two anchor ear seats 9 are separately fixed at two of being positioned at bracing frame 6 both sides and vertically move on the plate 3.Vertically move plate 3 through HSR25RL line style slide rail 2 along anchor ear axially on be slidingly arranged in the channel-section steel 4.
Four anchor ears 10 are coaxial.When between two hoops 11 of cable at anchor ear 10, can cable be compressed through bolt.
Bracing frame 6 mainly is made up of two channel-section steels 12, channel-section steel 12 bottoms through HSR25RL line style slide rail 5 be parallel to anchor ear axially on be slidingly arranged on the channel-section steel 4.Laterally travelling carriage (HSR25RL line style slide rail) 8 perpendicular to anchor ear axially on be slidingly arranged on the channel-section steel 12.
