Embodiment
Further details of explanation is done to the present invention with reference to the accompanying drawings and detailed description, it should be appreciated that
Protection scope of the present invention is not limited by embodiment.
As shown in figs. 1-7:Insulator chain suspension auxiliary lifting appliance in the present invention includes two hook-type side plates, 1, two connection
Plate 2 and two hanger intermediate plates 3, two 1 parallel distributions of hook-type side plate, the crotch area of two hook-type side plates 1 form fixed notch 10,
It is fixedly connected between two hook-type side plates 1 by two connecting plates 2, connecting plate 2 is provided with the first mounting hole 8, and three on insulator chain
Angle yoke plate 12 is provided with the second mounting hole 9, and 12 times end edges of triangle yoke plate are placed in fixed notch 10, and bolt 5 is pacified through first
Fixed after the dress mounting hole 9 of hole 8 and second using nut 6, suspender is fixedly connected by bolt 5 with nut 6 with insulator chain.
Welded plate 4 is provided between connecting plate 2 and hook-type side plate 1, and welded plate 4 is welded on connecting plate 2 and hook-type side plate 1
On, in order to prevent that nut 6 skids off the post of bolt 5 influence construction safety in hoisting process, the bolt 5 is designed as antiskid bolt 5, i.e.,
Set the through hole extended radially through, after installing nut 6, split pin 7 is inserted in through hole in the end of thread of bolt 5.For the ease of
The regulation of antiskid bolt 5 positions, and the first mounting hole 8 on connecting plate 2 is waist-shaped hole.For the ease of suspender and lifting block group
Connection, shackle mounting hole 11 is set on hanger intermediate plate 3.
, will using the auxiliary lifting appliance by taking the suspension of ± 1100kV UHVDC Transmission Lines engineering angle tower strain insulators insulator string as an example
Insulator chain is lifted to the method for angle tower cross-arm:
1st, equipment prepares
The equipment used in ultralong overweight wire insulation substring overall time hoisting process includes:Motor-driven grinding mill, lifting
Tackle pulley, load clamp, corner block, auxiliary lifting appliance.
1) motor-driven grinding mill
Using 5t gasoline type motor-driven grinding mills.
2) lifting block group
Lifting block group includes lifting block and hoist rope.Lifting block uses 160kN tackle pulleys (4-3).Lifting
Steel wire rope (mill rope) uses the steel wire ropes of Φ 13 (Nominal Tensile 1670MPa, Fracture Force 94.5kN, weight 0.706kg/m).
3) load clamp
Load clamp uses 16t shackles.
4) corner block
Corner block uses 5t speciality corner blocks, for steering of the hoist rope (mill rope) on cross-arm.
5) auxiliary lifting appliance
Because strain insulator string of ultrahigh voltage transmission line is coupled structure using tetrad or six more, for whole string can be accomplished simultaneously
Lifting, need the auxiliary lifting appliance in the present invention.
The 2nd, top gold utensil is installed
UHVDC Transmission Lines angle tower group immediately, installs the tower of strain insulator string first in advance on cross-arm hanging hole
Gold utensil (GD trunnion hanging panels).Finished and after intermediate acceptance is qualified when angle tower group is vertical, high-altitude is by strain insulator string top
Gold utensil (U-shaped link+adjustment plate+length parallel hanging plate+towing plate+short parallel hanging plate) with the first tower of cross-arm gold utensil (hang by GD gudgeons
Plate) installation.
The 3rd, auxiliary lifting appliance is installed
On the ground, strain insulator string top triangle yoke plate 12 is installed with auxiliary lifting appliance.Auxiliary lifting appliance uses spiral shell
Bolt 5 is fixedly connected with 2 mounting holes on triangle yoke plate 12.
4th, lifting block group (steel wire rope) is connected
On the ground, 16t lifting block group fixed blocks are connected with auxiliary lifting appliance mounting hole using 16t shackles.
5th, insulator chain is assembled
On the ground, insulator chain is assembled using overhanging way, i.e., lifting tackle pulley is first passed through into load clamp and auxiliary
Suspender is connected, and auxiliary lifting appliance is fixedly connected with bolt 5 with 2 mounting holes on triangle yoke plate 12, as lifting tool.
Lifting tackle pulley is lifted, insulator is connected with gold utensil piecewise, until whole string installation, four strings or six string insulation
Stout carrying pole or the reliable colligation of the lumps of wood are used between son, prevents mutual damaged in collision.
When assembling starts, first start ground 5t motor-driven grinding mills, auxiliary lifting appliance is lifted slightly.When auxiliary lifting appliance is apart from ground
During about 1m, start that insulator is installed, ball-eye should be connected reliably with insulator during connection, porcelain vase the rim of a bowl direction is answered unanimously.
Lift slightly after every 3 insulators install, then by auxiliary lifting appliance, continue that insulator is installed.When insulator installs
Afterwards, it is then the installation of insulator bottom is good (in addition to the gold utensil of connection suspension clamp).
6th, integral lifting
After strain insulator string installs, start ground 5t motor-driven grinding mills, integral lifting strain insulator string.
7th, high-altitude is installed in place
When short hardware string (the GD trunnion hanging panels+U-shaped link that the hanging hole of triangle yoke plate 12 is installed in advance close to below cross-arm hanging hole
Parallel hanging plate+the towing plate of+adjustment plate+length+short parallel hanging plate) when, stop motor-driven grinding mill traction.High-altitude personnel will be short parallel afterwards
Hanging plate is connected with the hanging hole of triangle yoke plate 12.
8th, lifting block group and auxiliary lifting appliance are removed
Start motor-driven grinding mill, return loose hoist rope (mill rope), when lifting block group does not stress completely, high-altitude personnel tear open
Except auxiliary lifting appliance and lifting block group.
Hook-type side plate 1 in hoisting process in auxiliary lifting appliance is stuck in the lower end edge of triangle yoke plate 12, and holds up insulation upwards
Substring.
Above-mentioned hanging method is only the preferred method of the present invention, and those skilled in the art will be understood that the base in the above method
The simple transformation carried out on plinth still falls within protection scope of the present invention.
