Abstract
The utility model relates to the technical field of high-voltage power transmission ling construction, and discloses a lifting tool for an overhead ground wire of a steel pipe pole. The lifting tool comprises a steel pipe pole crossarm clamp, a pulley support and an upturned pulley, wherein the steel pipe pole crossarm clamp, together with a lower clamp hoop (2) and an upper clamp hoop (3), is fixed on a crossarm (1) through clamp connecting screws (4); the pulley support (5) is welded on the upper clamp hoop (3); the upturned pulley is fixed on the pulley support (5) through a base connecting screw (6); a movable sealing plate (14) is arranged at the upper part of the upturned pulley and fixedly connected with a spring pin (11) through a sealing screw (10); and the spring pin (11) is connected with a pin rope hanging ring through a cotter pin sling (12). The lifting tool provided by the utility model prevents a lifting rope from dropping off the pulley, achieves the purpose of convenience in both disassembly and assembly, overcomes the difficulties in applying a conventional wire lifting tool to the steel pipe pole, has a simple structure, is convenient to operate, reduces labor intensity, eliminates potential safety hazards and improves the work efficiency.
Description
Technical field
The utility model relates to a kind of technical field of high voltage circuit construction, relates in particular to a kind of steel pipe pole overhead ground wire and carries the Line tool.
Background technology
At present the steel pipe pole overhead ground wire is installed and is adopted manpower to install pickaback or with the method that suspension wire grip etc. is carried line, because steel pipe pole itself is constructed, more than installation exists following problem:
1. because cross-arm is far away apart from shaft, stand in the method that adopts on the shaft cat ladder pickaback, work high above the ground personnel less stable is installed inconvenient.
Stand in the method that adopts on the upper conductor cross-arm pickaback and install, can not make ground wire rise to the installation site pickaback for lead cross-arm and ground wire cross-arm distance bar type far away.
2. on the ground wire cross-arm, promote ground wire with portable method; Because ground wire cross-arm cross section is less; The operating personnel's balanced capacity that is sitting on the cross-arm is poor; When promoting ground wire and installing tool materials are come off and cause the injury of ground being assisted installation personnel, even cause ground wire to fall to cause construction accident with portable method.
3. adopt the method for suspension to promote with common instrument; Because steel wire overlaps and puies forward the length of the Line tool itself; Can not ground wire be risen to the installation site,, and in the lifting lifting process, cause wire grip crimp easily if adopt wire grip to be fixed to not only fixing difficulty above the ground wire cross-arm; The damage of ground wire cross-arm, the safe operation after being unfavorable for putting into operation.
Summary of the invention
For overcoming the deficiency of prior art, the purpose of the utility model provides a kind of steel pipe pole overhead ground wire and carries the Line tool, has overhead ground wire simple in structure, reasonable in design, safe and reliable, as to be fit to steel pipe pole use installation and carries the Line tool.
Be the foregoing invention purpose that realizes, the utility model adopts following technical scheme:
A kind of steel pipe pole overhead ground wire is carried the Line tool; Comprise: steel pipe pole cross-arm jig, coaster support, a coaster towards the sky; Said steel pipe pole cross-arm jig is fixed on the cross-arm 1 with last anchor ear 3 through anchor ear 2 under jig connection screw 4 and the jig; Coaster support 5 is welded on the jig on the anchor ear 3, connects screw 6 towards day coaster through base and is fixed on the coaster support 5, is provided with activity hush panel 14 towards day coaster top; Activity hush panel 14 is fixedly connected with spring catch 11 through sealing screw 10, and spring catch 11 links to each other with pin rope link through split pin lanyard 12.
Owing to adopt technique scheme, the utlity model has following advantage:
1, make the operating personnel when ground wire is installed; Need not be pickaback according to the characteristics of various steel pipe pole types; Install the position that can be chosen in shaft cat ladder, lead cross-arm, ground wire cross-arm, has avoided that disequilibrium causes the high-altitude short distance to fall in the lifting process.
2, avoided in the installation process with pickaback or portable lifting ground wire, also will take into account simultaneously and install and cause tool materials to come off in the air from height.
3, adopt open-close type to seal towards day coaster and combine the spring catch locking, avoided ropes from coaster, to come off, realized demolition, installation purpose easily.
4, use this to carry the Line tool and overcome other lifting instrument and can not promote the difficulty that puts in place with carrying line, also avoid the stressed damage that the ground wire cross-arm is caused of steel wire cover single-point simultaneously because of steel wire rope hanging sleeve and the length of carrying the Line tool itself.
5, this is carried the Line tool and is not only applicable to the installation of new stringing road steel pipe pole lifting ground wire, also is applicable to pitching and promoting ground wire when line maintenance simultaneously.
6, this instrument has advantages such as simple, safe and reliable, operating efficiency height rational in infrastructure.
Description of drawings
Fig. 1 a carries the Line tool sketch map for the steel pipe pole overhead ground wire,
Fig. 1 b is the end view of Fig. 1 a;
Among the figure:1, ground wire cross-arm, 2, anchor ear under the jig, 3, anchor ear on the jig, 4, jig connects screw; 5, coaster support, 6, base connects screw, 7, towards a day apparatus for suspension, 8, the pulley fixed screw; 9, pulley, 10, seal screw, 11, spring catch; 12, split pin lanyard, 13, pin rope link, 14, the activity hush panel.
Embodiment
Shown in Fig. 1 a, 1 b; A kind of steel pipe pole overhead ground wire is carried the Line tool; Comprise: steel pipe pole cross-arm jig, coaster support, towards a day coaster, said steel pipe pole cross-arm jig connect through jig that anchor ear 2 is fixed on the cross-arm 1 with last anchor ear 3 under screw 4 and the jig, and coaster support 5 is welded on the jig on the anchor ear 3; Connecting screw 6 towards day coaster through base is fixed on the coaster support 5; Be provided with activity hush panel 14 towards day coaster top, activity hush panel 14 is fixedly connected with spring catch 11 through sealing screw 10, and spring catch 11 links to each other with pin rope link through split pin lanyard 12.
This ground wire lifter method for using: connect screw 4 through jig anchor ear 3 on anchor ear under the jig 2 and the jig is linked to each other, jig is fixed on the cross-arm 4, reeve pulley 9; Through sealing screw 10, activity hush panel 14 and spring catch 11 coaster is shut, in order to avoid rope comes off, the ground wire that rope one end will promote ties; Ground assistance personnel spur the position that rope to ground wire need install and install; Pull out spring catch 11 after installing, open movable link plate 14, can remove rope; Is in order to prevent that in operation process spring catch 11 from coming off with design pin rope link 13 on the apparatus for suspension 7 with split pin lanyard 12; Can spring catch 11 be removed direct pull split pin lanyard 13 when the operating personnel is chosen in lead cross-arm or the installation of steel pipe pole cat ladder position simultaneously, the swing rope makes activity hush panel 14 deviate from from sealing screw 10, and rope is removed; When the operation personnel installed on ground wire cross-arm 1, spring catch 11 can be selected to wear from the top down.If when the cross section of cross-arm was not the hexagon shown in figure one, carrying the Line tool jig can be according to the alteration of form jig structure of ground wire cross-arm, its method for using is identical.
