Technical field
The utility model relates to the Work tool in a kind of electric power operation, relates in particular to a kind of a kind of transformer substation grounding wire mounting or dismounting elevator that is used for substation's eminence mounting or dismounting grounding jumper.
Background technology
When arranging the maintenance task, needing work-site to arrange various safety measures in the electric system, is to guarantee one of safe important means and install grounding jumper in the job site both sides.Substation's mounting or dismounting grounding jumper is regular work of operations staff, but because 110KV and above substation equipment installation site height, equipment end hangs the position major part of grounding jumper point all more than 5 meters, and the grounding jumper insulation rod generally has only about 3 meters, so cause in the operating process operating personal of hanging, disconnect ground wire need stand in the enterprising line operate of double ladder, perhaps being subjected to position limit in some occasion can only be mounting or dismounting grounding jumper violating the regulations.The grounding jumper three-phase is conjuncted, Heavy Weight, insulation rod are long, the people stands on the ladder and hangs, disconnects in the ground line process and rocks severity, the power that consumes again consuming time, simultaneously because substation's intensive layout in charging equipment chamber, as in mounting or dismounting grounding jumper process as run-off the straight or fall down, may touch adjacent charging equipment, very easily cause casualties or the electric grid large area power cut accident, in the whole operation process, have bigger security risk.
Summary of the invention
The purpose of this utility model is: the mounting or dismounting easy device that grounding jumper is used is provided in a kind of power system operation, eliminates operating personal and install and remove grounding jumper process safe risk aloft, prevent personal injury or cause the generation of large area blackout.
The purpose of this utility model realizes by following scheme: be made up of waggon, crank, wheel chain assembly, stay cord, clamper, expansion link and four wheels being arranged at base plate bottom, expansion link is fixed on the waggon base plate, be installed on the support of waggon in order to the flexible wheel chain assembly of control expansion link, crank is connected with the wheel chain assembly, clamper is contained in the expansion link top, and stay cord is connected on the clamper in order to control the opening and closing of clamper.
Clamper described in the utility model is made up of cylindrical shell, the importing cover that is arranged at the cylindrical shell top, movable support, spike, bolt, extension spring, fixed cover, cylindrical shell trisection fluting embeds spike, the lower end of spike is contained on the groove of movable support, spike is connected on the cylindrical shell by interior hexagonal pin bolt, movable support is enclosed within on the outer wall of cylindrical shell, and movable support is connected on the cylindrical shell by three extension springs.
For ease of the insertion of grounding jumper insulating bar, clamper top is exit skirt.
For increasing the stability of installing in the operating process, wheel of the present utility model has four, and wherein two can be pinned, and is symmetrically installed with six telescopic feets simultaneously on base plate.
The utility model advantage is: the operation task of original aloft work is converted on the ground finishes, can effectively prevent the generation of human casualty accident and power grid accident, alleviate labor intensity of operating personnel, shortened the operating time, further improved the reliability of mains supply.Simultaneously, can be widely used in relevant specialities such as substation's high-potting, relaying relates to eminence and tears work such as hanging test wire open.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the external form figure of one of the utility model assembly clamper;
Fig. 3 is that the A of Fig. 2 is to cutaway view.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
Referring to Fig. 1, the utility model is made up of waggon 1, crank 2, wheel chain assembly 3, six telescopic flexible support legs 4, stay cord 5, clamper 6, expansion links 7 and four wheels 8 being arranged at base plate 9 bottoms, wherein expansion link 7 usefulness screws are fixed on waggon 1 base plate 9, be installed on the support of waggon 1 in order to the flexible wheel chain assembly 3 of control expansion link, crank 2 is connected with wheel chain assembly 3, makes chain drive expansion link 7 actions by operating rocker handle 2.Two can be pinned in four wheels 8, and six flexible support leg 4 symmetries are installed on the base plate.Clamper 6 is contained in expansion link 7 tops, and stay cord 5 is connected on the clamper 6 opening and closing in order to the control clamper, and for ease of the insertion of grounding jumper insulating bar, clamper 6 upper design are exit skirt.
Referring to Fig. 2,3, clamper 6 is made up of cylindrical shell 61, the importing cover 62, movable support 63, spike 64, interior hexagonal pin bolt 65, extension spring 66, the fixed cover 67 that are arranged at cylindrical shell 61 tops.The grounding jumper insulation rod is inserted in the cylindrical shell 61 by importing cover 62, and with the upper end of cylindrical shell 61 trisections fluting embedding spike 64, the lower end of spike 64 is contained on the groove of movable support 63, and spike 64 is connected on the cylindrical shell 61 by interior hexagonal pin bolt 65.Movable support 63 is enclosed within on the outer wall of cylindrical shell 61, and movable support 63 is connected on the cylindrical shell 61 by three extension springs 66.
Can insert the insulating bar of diameter in the 35-45cm scope in clamper 6 cylindrical shells, control the opening and closing state of clamper on the ground, finish the insertion of insulating bar, the whole operation process of holding with a firm grip, extracting by clamper 6 plug-in stay cords 5.
The principle of work of clamper is as follows: under the normal circumstances, extension spring 66 is connected movable support 63 on the cylindrical shell 61, and the upper end of spike 64 is inserted in the cylindrical shell 61, makes the insulating bar of grounding jumper to insert.When stay cord was drop-down, movable support 63 moved down, and slided in movable support 63 groove track to intrinsic displacement because of spike 64 lower ends, and lever principle (is fulcrum with interior hexagonal pin bolt 65) spike moves outside 64 upper ends, and the grounding jumper insulation rod can insert.After the grounding jumper insulation rod is inserted into cylindrical shell 61 bottoms, unclamp stay cord 5, under the effect of extension spring 66, to move on the movable support 63, opposite process drives the spike 64 upper ends grounding jumper insulation rod of holding with a firm grip.
The utility model grounding jumper assembling and dissembling process is as follows:
1, installing ground wire: dolly is pushed under the hitch point, pull down the dolly wheel snap close, load onto expansion link, the ground wire insulating bar is inserted in the clamper, hand expansion link omits the high position directly over rising to ground wire hitch point lead, the decline expansion link touches lead with the ground wire bayonet socket, and drop-down stay cord blocks lead with bayonet socket.
2, grounding jumper breaks away from elevator: after the ground wire bayonet socket blocked, drop-down clamper stay cord unclamped clamper, and the whole process of suspension grounding jumper is finished in slowly decline after hand expansion link is separated from ground wire insulation rod and elevator, is transferred to the operation of next phase subsequently.
The dismounting of grounding jumper: dolly is pushed into the below that to remove ground wire, the rising expansion link is to the position that can touch insulation rod, insulation rod is introduced the exit skirt of clamper by guide rope, rising is slowly inserted insulation rod in the clamper, raise again after holding with a firm grip the ground wire bayonet socket to be deviate from from lead by insulation rod, after lead was avoided in slight travelling car position, the decline elevator was extracted insulation rod and can be finished whole dismounting ground line process to ground.
