Description
Technical field
The utility model relates to a kind of primary cut-out assembling and setting device, and hand-operating device is used in specifically a kind of 550kV circuit breaker assembling.
Background technology
Along with China's sustainable development of economy, the demand of electric power is continued to increase, developed area usually, being in great demand of electric power only relies on this locality to be difficult to satisfy electricity needs, and therefore, transmission of electricity becomes a big characteristic of China at a distance.The transregional networking of domestic electric power for reducing power consumption, is adopted the electric pressure of 550kV.The transmission line of 550kV grade when conveying capacity, change important unusually.The requirement of circuit breaker stability is also being improved, therefore, designing various frocks and improve circuit breaker quality precision and become a kind of necessity.
Dual-port series connection form is adopted in the design of 550kV circuit breaker at present more, and the part situation switching-on resistance of also need connecting is accumulate to mechanism side, and operating physical force is very big, can not manual action.But adjusting inner in the assembling process needs very high precision, comprises the assembling of closing position, main tie etc., and after assembling is accomplished, needs action several times, to confirm no catching phenomenon.Operation is in the past adopted hydraulic mechanism to drive through connector and is accomplished, and the hydraulic mechanism operative employee is bigger, and movement velocity is very fast; The defective that occurs in the very difficult discovery motion process, and be unfavorable for assembling, be unfavorable for debugging; These deficiencies can cause the life-span to shorten when operation, are prone to take place operation troubles.
Summary of the invention
The utility model provides a kind of simple in structure, easy to operate in order to overcome above-mentioned defective, and hand-operating device is used in the 550kV circuit breaker assembling of being convenient to debug.
The technical scheme that the utility model adopts is: hand-operating device is used in a kind of 550kV circuit breaker assembling, comprises connector, it is characterized in that: also comprise screw mandrel, nut, fixed support and bearing; Described screw mandrel one end is connected with drive unit, and the sheathed bearing in the other end outside is on screw mandrel, be provided with nut near that section of bearing; Described Bearing Installation is in bearing pedestal; Bearing pedestal is arranged on the rear side of connecting axle, and the connecting axle front side is connected with breaker body transmission main tie, and described nut is connected with fixed support through bolt; Fixed support is drum shape, and support bracket fastened front side promptly is connected with connector away from that side of nut.
The utility model has designed feed screw nut and has carried out transmission, and leading screw one end is connected with drive unit, and the other end stretches in the bearing, and bearing is connected with pull bar through connecting axle again; Leading screw is provided with nut, and nut is connected with fixed support, and the fixed support opposite side is connected with connector; When drive device drives leading screw rotation, nut just can drive the fixed support reach or after move because bearing has been offset the rotation of leading screw front end; Therefore connecting axle and pull bar neither can move also and can not rotate; And connector can reach under the support bracket fastened drive or after move, form pull bar and connector relative displacement slowly, realized the slow separating brake of equipment or slowly combined floodgate debugging operations.
Description of drawings
Fig. 1 is the sketch map of the utility model.
Embodiment
Combine accompanying drawing that the utility model is further described, the technical scheme of the utility model is at present: hand-operating device is used in a kind of 550kV circuit breaker assembling, comprises connector 1; Also comprise screw mandrel 2, nut 3, fixed support 4 and bearing 5, described screw mandrel 2 one ends are connected with drive unit, the sheathed bearing 5 in the other end outside; On screw mandrel 2, near that section of bearing 5 nut 3 is set, described bearing 5 is installed in 5 on the bearing, 5 rear sides that are arranged on connecting axle 6 of bearing; Connecting axle 6 front sides are connected with pull bar 7; Connecting axle 6 in the present embodiment is the thick middle thin step axles in two ends, and bearing 5 cover for seat also are provided with sealing ring in the outside of connecting axle 6 rear ends between 5 on bearing and connecting axle 6; The front end of connecting axle 6 can be connected with pull bar 7 through axle sleeve; Also can be connected with pull bar 7 through nut 3, the connecting axle 6 of the utility model can also be other class formations, holds 5 other end cylinder lever connecting rods 7 and just can as long as can satisfy an end connecting axle 6.Described nut 3 is connected with fixed support 4 through bolt, and fixed support 4 is drum shape, and the front side of fixed support 4 promptly is connected with connector 1 away from nut 3 those sides, and connector 1 is connected with equipment such as Shell of circuit breaker to be tested through bolt.Drive unit in the utility model is generally manual actuation, like die nut or torque spanner.
The utility model is based on worm drive, and worm drive are that the screw pair of utilizing leading screw and nut 3 to form realizes what transmission required, and it can change circumnutation into rectilinear motion, transmits motion and power simultaneously.During use, through drive device drives leading screw rotation, nut 3 just can drive fixed support 4 reaches or after move; Because bearing 5 has been offset the rotation of leading screw front end, so connecting axle 6 and pull bar 7 neither can move also and can not rotate, and pull bar 7 is an inactive state; And connector 1 can the reach drive of fixed support 4 under or after move, form pull bar 7 and connector 1 relative displacement slowly, the utility model can realize through the direction of rotation that changes leading screw connector 1 reach and after the conversion that moves; The conversion operations of realization equipment separating brake or combined floodgate, because the utility model operated by manual actuation, the moment during the leading screw rotation is much larger than the main body coupling part of moving; Thereby make operating physical force much smaller than straight moving required power; Feasible operation is more light, and has realized slow separating brake of equipment or the action of closing a floodgate slowly, is convenient to debugging operations.
The utlity model has simple in structure, easy to operate, the characteristics of being convenient to debug.
