During maintenance, base is fixed on ground.Tripod contributes to the steadiness improving base.More piece elevating lever 18 is hydraulic lifting arm, flexible adjustment height under the control of oil pressure.Connect outside oil pump by hydraulic oil interface 21 and oil pressure is provided, drive hydraulic lifting arm lifting.Adopt hydraulic oil to carry out lifting to drive, transmit motion homogeneous steady, can realize stepless speed regulation, hydraulic means is easy to realize overload protection by means of arranging overflow valve etc.
On the outer peripheral face of the base that three supporting legs of tripod 15 distribute equably.When needs are opened, pull out the lower end of feet.Due to feet, support bar be hinged and and be also articulated and connected between base, therefore feet and support bar are recoverable to and are close on the outer peripheral face of base, so can conserve space, are convenient to storage.During concrete enforcement, groove can be set on the outer peripheral face of base in order to hold supporting leg, thus tripod is taken in completely in groove, make lowering or hoisting gear 14 profile more attractive in appearance.
When being elevated to suitable position, by controller opens electric rotating machine, controlling four paws clip and rotating, and then drive card adapter plate, rotation axis to rotate, card adapter plate, rotation axis, the rectilinear movement of mobile chuck, control opening and clamping of jig arm simultaneously.
Described card adapter plate 9 is connected with a four paws clip 12, and drives rotation by described four paws clip 12.When card adapter plate 9 is rotated, described rotation axis is driven to rotate.Be threaded between rotation axis with described pedestal, form a feed screw nut pair therebetween.Pedestal fixing is equivalent to nut, and rotation axis is equivalent to screw mandrel.Therefore rotation axis is while rotation, also can move axially in screwed hole, thus drive mobile chuck to move up and down, and then realize clamping and the release of two jig arm.During specific works, the chuck of two jig arm for clamping repair apparatus or wire, thus realizes the ground connection of repair apparatus or wire.Earth pile-head, between earth connection with jig arm conduction be connected, to be grounded function.
Described first jig arm 4 and the second jig arm 5 include chuck 10 and the body of rod 11; The bottom of the described body of rod 11 is articulated with the top of pedestal 1, and described chuck 10 is provided with the top of the described body of rod 11; The chuck 10 of described two jig arm is oppositely arranged, and just can clamp wire when the chuck 10 of two jig arm fastens mutually.
The inner side of described chuck is the deep-slotted chip breaker of indent, and when two chucks abut against, two deep-slotted chip breakers fasten mutually, just clamp wire.
Described pedestal 1 comprises cylinder 101 and Rotary-table 102, and cylinder 101 is positioned at above Rotary-table 102 and the two is coaxially arranged; Described jig arm is positioned at described cylinder 101 top; Described screwed hole is positioned at the center of described cylinder 101 and coaxial with described cylinder 101; Described Rotary-table 102 is the structure of hollow; Described card adapter plate 9 is arranged in the inner chamber of described Rotary-table 102.
Described tripod 15 comprises three supporting legs; Described supporting leg comprises feet 1501 and support bar 1502; The upper end thereof of described feet 1501 is in the outer peripheral face upper end of described base 20, and the lower end of described feet 1501 is connected on ground; One end of described support bar 1502 is articulated with the middle part of described feet 1501, and the other end of described support bar 1502 is articulated with the outer peripheral face lower end of described base 20.
Described card adapter plate 9 is made up of two cross one another plate bodys.
Two mutual square crossings of plate body, or become X-shaped to intersect, form four mutually isolated regions.Four claws 1201 of four paws clip 12 lay respectively in a region.When four paws clip 12 rotates, card adapter plate is also driven to rotate.When card adapter plate is rotated, can move linearly along with the axis of rotation axis along described pedestal, card adapter plate also moves in described four paws clip.Because four paws clip has certain degree of depth, namely described claw has certain height, therefore card adapter plate can not and described four paws clip between be separated.Four paws clip 12 is positioned at lowering or hoisting gear top.
During concrete enforcement, ground connection gripping organization establishes is in the top of the described lowering or hoisting gear 14 as Fig. 2.Ground connection gripping body is positioned over described lowering or hoisting gear top, card adapter plate 9 and four paws clip 12 clamping mutually.When ground connection gripping organization establishes is on lowering or hoisting gear top, card adapter plate 9 just with the clamping of four paws clip 12 phase; Even if card adapter plate also can not depart from the control of four paws clip 12 when moving up and down, move up and down in the altitude range of four paws clip 12.In order on lowering or hoisting gear 14 is firm and ground, tripod 15 is set in the lower end of lowering or hoisting gear.
Four paws clip 12 is fixed on a rotating shaft 16, and described rotating shaft 16 is by driven by motor.When driven by motor four paws clip 12 rotates, can rotate by driver card fishplate bar, thus drive rotation axis and moving blockage rim moving axially of described pedestal, and then realize clamping and releasing of two jig arm.
As Fig. 1, mobile chuck is arranged two holes, the body of rod of described each jig arm inserts in a hole.The body of rod bottom of two jig arm is articulated with on pedestal, and the spacing of the hinge point of two jig arm is less than the spacing in two holes of mobile chuck; Therefore move chuck can not drop in hinge point, can stop declining higher than hinge point part at certain.And because the distance between two holes is fixing, and be set to when mobile chuck moves to the body of rod top of jig arm, the chuck of two jig arm fastens just mutually, realizes the pinching action of chuck.When mobile chuck declines from body of rod top, the spacing between two chucks increases, and realizes the release movement of chuck.The lifting of mobile chuck realizes controlling by the electric rotating machine of four paws clip.
High-altitude of the present invention earthing device, ground connection gripping body needs configuration lowering or hoisting gear 14 to use.
