Description
Technical field
The utility model relates to a kind of tool special for dismounting of power disconnecting switch connecting rod straight pin.
Background technology
The isolating switch movable part of outdoor transmission line of electricity, because long term exposure is in air, is subject to the erosion of the natural conditions such as wind and weather, very easily causes corrosion bite and the mechanically deform of the drive disk assemblies such as connecting rod, causes contact not same period, affects the normal operation of transmission facility.In the time of disconnecting link overhaul, need first connecting rod straight pin be pulled down, but Chang Yinqi corrosion bite is serious, dismantle very difficult; In addition, in unloading process, often need to beat straight pin with instruments such as hand hammers, cause straight pin top deformed dilation and arm-tie bending, also strengthen the difficulty of straight pin dismounting.Thereby affecting repair schedule,, there is the problems such as repair time prolongation in restriction operating efficiency, makes troubles to enterprise's production and resident living.
Utility model content
The utility model technical issues that need to address are to provide a kind of simple in structure, easy to use for dismantling the instrument of isolating switch connecting rod straight pin.
For addressing the above problem, technical solution adopted in the utility model is:
A kind of isolating switch connecting rod straight pin extracting tool, comprise load base plate, top board and screw nut driving mechanism, wherein screw nut driving mechanism comprises and is opened in the screwed hole at top board middle part and the screw mandrel being equipped with mutually with screwed hole, described screw mandrel top is screw mandrel head, the through hole that boosting-rod is installed is set on screw mandrel head, described base plate middle part offers the via hole through isolating switch connecting rod straight pin, via hole and leading screw coaxial line; The both sides that are positioned at screwed hole on described top board are provided with connecting bolt, on described base plate, offer the rectangular groove of an end opening with the corresponding position of connecting bolt, rectangular well width mates with connecting bolt diameter, two rectangular separation are identical with the spacing of connecting bolt that is arranged on top board two ends, and connecting bolt bottom is positioned in rectangular groove.
Improvement of the present utility model is: described top board intermediate thread bore portion is thickening plate, and on the outstanding top board of top board, the reinforcement of end face is cylindrical.
Further improvement of the utility model is: described screw mandrel bottom arranges hexagonal hole, and push rod is installed in hole, and push rod upper end is the outer hexagonal structure coordinating with hexagonal hole.
The beneficial effect that adopts technique scheme to produce is:
The utility model adopts feed screw nut's structure, the circular-rotation of screw mandrel is converted to rectilinear motion, thereby straight pin is ejected, simple in structure, easy to use.Push rod and screw mandrel assembling are used, and can change as required, and load base plate adopts rectangular groove connecting bolt, convenient when use.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model base arrangement schematic diagram;
Fig. 3 is that the utility model screw mandrel part is analysed and observe;
Wherein: 1, base plate, 2, connecting bolt, 3, top board, 4, through hole, 5, screw mandrel, 6, push rod, 7, via hole, 8, rectangular groove, 9, hexagonal hole.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, this novel load base plate 1, top board 3 and screw nut driving mechanism of comprising, wherein top board 3 two ends arrange connecting bolt 2, connecting bolt 2 is connected with base plate 1, is provided with the via hole 7 through straight pin in the middle of base plate 1, is provided with screwed hole in the middle of top board, screw mandrel 5 is installed in screwed hole, top board and screw mandrel form screw nut driving mechanism, and described screw mandrel 5 tops are screw mandrel head, and the through hole 4 that boosting-rod is installed is set on screw mandrel head.
Basis is novel to be facilitated in use in order to guarantee, convenient while that is to say clamping isolating switch connecting rod straight pin, base plate is made into the form that can dismantle at any time, offered the rectangular groove of two end openings at this Novel bottom plate for this reason, rectangular well width mates with connecting bolt diameter, and two rectangular separation when being arranged on the identical use of spacing of connecting bolt at top board two ends, connecting bolt and insert base plate, base plate is stressed in the time of work, and the bottom surface of base plate holds out against the bolt head of connecting bolt.
For proof strength, extend screw mandrel service life, the screwed hole part in the middle of this novel top panel is thickening plate, the reinforcement of the outstanding upper end face of top board is cylindrical.Certainly, ledge above also can adopt welding manner and top board to weld together, and then processing screw thread, to guarantee fitness and precision.
The push rod on screw mandrel top uses for a long time, may occur wearing and tearing and situation about damaging, for easy maintenance and replacement, reduce maintenance cost, screw mandrel and push rod are separated, in screw mandrel bottom, hexagonal hole is set, push rod is installed in hole, and push rod upper end is outer hexagonal structure, coordinates with hexagonal hole.
Operation principle: the screw-drive mechanism that the utility model utilizes screw mandrel and nut composition by the rotation of screw mandrel be converted to screw mandrel and push rod rectilinear motion, in the hole of screw mandrel head, boosting-rod is installed, increase the arm of force, be converted into the rectilinear motion of screw mandrel by the rotation of screw mandrel, form the powerful thrust to isolating switch connecting rod straight pin, promote isolating switch connecting rod straight pin, push rod advances and replaces straight pin jacking pin-and-hole, make it be pushed out pin-and-hole, disassemble.Concrete operation step is: the top of the straight pin of isolating switch connecting rod being aimed to push rod, make the axis of isolating switch connecting rod straight pin and the dead in line of push rod, place base plate, via hole and the straight pin of its bottom surface are aimed at, rotary screw rod makes base plate load, then add that boosting-rod rotates, and ejects the connecting rod straight pin of isolating switch.
