Completely solved the problem of overhauling the GW6 type isolating switch.
Description
Technical field
The utility model belongs to the service kit of converting equipment GW6 type isolating switch.
Background technology
Because characteristics such as the high voltage isolator volume is big, Heavy Weights, so at the turnover job of high voltage isolator, the scheme that generally adopts is to use crane and lift truck to cooperate to come the field overhaul of facilities and equipments at present.But the overhaul of some isolating switch often is subjected to the restriction of charging equipment on every side, and safe distance is not enough, though the load-carrying of crane and lift truck is very big, because its radius of clean-up is bigger, integral body takes up room also bigger, bump charging equipment very easily by mistake, electric shock accidents takes place; At this moment, crane, lift truck can't use; In addition, turnover job in the past, very big to the dependence of crane and lift truck, there is not their work to carry out, and also very expensive aspect the usage charges of vehicle and driver personnel's input, Jian Xiu cost has just increased greatly like this.At this moment, just need a kind of simple in structure, install and use convenient instrument and break through this restriction.
Summary of the invention
Technical problem to be solved in the utility model provides the on-the-spot disintegration overhaul of a kind of high voltage isolator specific purpose tool, to the dependence of crane and lift truck, reduces the vehicle cost of use when breaking away from the isolating switch overhaul, solves the difficult problem that three-phase can not disintegrate simultaneously and overhaul.
The on-the-spot disintegration overhaul of the utility model high voltage isolator specific purpose tool, comprise base support, base support top one side is provided with workbench, the center that it is characterized in that described base support top is provided with axis, insert arm on the axis, movable pulley and one group of fixed pulley are installed on the arm, suspension hook is installed on the movable pulley, rope is by fixed pulley and movable pulley connecting shackle.
Wherein optimized technical scheme is:
Described base support is the triangular prism shape, and workbench is positioned at a side position of base support.
The bottom of the described base support shape that is rectangle, the bottom on base two long limits connects clamping plate respectively, and clamping plate are connected by hold-down screw with base support.The purpose that clamping plate are set is to make things convenient for the utility model and repair apparatus to be installed together, convenient maintenance.
Operation principle of the present utility model is:
During hoisting heavy, the suspension hook of movable pulley catches on weight, and the staff is drawing rope, by the work-saving device of assembly pulley, weight is sling; When weight rises to when unsettled, the staff may stand on the workbench of base support one side, promotes position and direction that unsettled weight just can be adjusted the weight landing gently.Two groups of hold-down screws and clamping plate are arranged at the bottom of base support, can be fixed on support firmly on the channel-section steel that supports the isolating switch base, kit just can be near the equipment that will overhaul like this, the scope of work reduces widely, whole working region is within the safe distance fully, so overcome the not enough problem of safe distance fully, has broken away from the dependence to equipment such as crane and lift trucks simultaneously, greatly reduce recondition expense, and reached disintegrate the simultaneously purpose of overhaul of three-phase.
Advantage of the present utility model:
On the channel-section steel that is fixed on the plant bottom case junction that the utility model can be easily firm, abut against on the repair apparatus, the radius of clean-up is little, and simple in structure, light and handy convenient, install and use simple and easy, one people just can independently install and use, and brings great convenience to service work.
This product structure is simple, dismounting is simple and convenient, is easy to produce, and production single-piece specific purpose tool only needs 300 yuan, not only can produce in batches, and have promotional value.In use, not only can reach the phase-splitting one man operation, but also can finish the disintegration overhaul to three-phase simultaneously.Thoroughly solved a GW6 type isolating switch overhaul difficult problem.And change the difficult situation that the past does not have crane, lift truck just can't carry out the work.This specific purpose tool vertical tension reaches 400kg.Isolating switch is separated about the about 100kg of weight of body portion, satisfies the lifting safe requirement fully.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an arm part-structure schematic diagram;
Fig. 3 to be base support with the channel-section steel that supports the isolating switch base fixedly connected schematic diagram.
Among the figure: 1 base support, 2 arms, 3 axis, 4 clamping plate, 5 fixed pulleys, 6 movable pulleys, 7 ropes, 8 pillars, 9 workbenches, 10 suspension hooks, 11 hold-down screws, 12 channel-section steels, 13 fixed dams
Embodiment
Below in conjunction with description of drawings the utility model.
As Fig. 1, the on-the-spot disintegration overhaul of high voltage isolator specific purpose tool, the base support 1 that comprises a triangular prism that forms by three pillars 8, base support top one side is equipped with workbench 9, a center welding axis 3 (can adopt steel pipe manufacturing) at base support 1 top inserts one by one according to the arm 2 of on-the-spot actual design on the axis 3, and arm 2 bottoms are provided with fixed dam 13 (as shown in Figure 2), its effect is that the restriction arm inserts the degree of depth of axis 3, and arm is freely rotated; Movable pulley 6 and the one group of fixed pulley 5 that designs in the known technology mode is installed on the arm 2, suspension hook 10 is installed on the movable pulley 6, rope 7 drives the operation of suspension hook 10 by fixed pulley 5 and movable pulley 6.The bottom of the base support shape that is rectangle, the bottom on base two long limits connects clamping plate 4 (angle steel) respectively, and clamping plate 4 are connected by hold-down screw 11 with base support.
As Fig. 3, clamping plate 4 are threaded to the inside grooves of the channel-section steel 12 (known configurations) that supports the isolating switch base, and make it become nearly 90 degree angles with channel-section steel, tighten screw, make two long limits of base support 1 bottom symmetry step up the supporting surface of channel-section steel respectively with clamping plate 4, thereby base support 1 is fixed on the channel-section steel 12 firmly.Contrast for convenience, the bottom of base support represents that with fine line channel-section steel 12 and hold-down screw 11 usefulness heavy lines are represented.
During hoisting heavy, the suspension hook 10 of movable pulley 6 catches on weight, and the staff is drawing rope 7, by the force-reducing device of assembly pulley, weight is sling; When weight rises to when unsettled, the staff may stand on the workbench 9 on the shelf, promotes position and direction that unsettled weight just can be adjusted the weight landing gently; The hold-down screw 11 and the clamping plate 4 of base support 1 bottom, can be fixed on support firmly on the channel-section steel 12 that supports the isolating switch base, kit just can be near the equipment that will overhaul like this, the scope of work reduces widely, whole working region is within the safe distance fully, so overcome the not enough problem of safe distance fully, has broken away from the dependence to equipment such as crane and lift trucks simultaneously, greatly reduce recondition expense, and reached disintegrate the simultaneously purpose of overhaul of three-phase.
