Abstract
The utility model discloses a primary connection rod clamping device for a mutual inductor for an automatic current mutual inductor detection line. The primary connection rod clamping device comprises an upper lever and a lower lever which are connected through a middle pin shaft, wherein two clamping blocks capable of swinging are arranged at the left end and used for clamping a primary conductive board of the mutual inductor, so that a loop is formed together with a measuring instrument; two connecting rods are hinged at the right end; a cylinder is pulled by a cylinder rod, so that the connecting rods are straightened up, and a function of increasing a clamping force is realized; and when the cylinder rod is pushed out, the connecting rods are inclined, and the two clamping blocks are opened, so that the conductive board of the mutual inductor is released.
Description
Technical field
The utility model relates to the full-automatic detection line of mutual inductor of electric system.Be specifically related to mutual inductor primary connection clamp device.
Background technology
Mutual inductor is the metrology devices of electric system, and is very big to the workload of its detection.In order to save manpower, improve accuracy of detection and efficient, national grid is promoted the application of the full-automatic detection line of mutual inductor.When on transfer matic, detecting the parameter of mutual inductor, need with mutual inductor once, secondary coil and ground connection seat board be connected on the detecting instrument.Wherein the contact resistance of primary connection influences measuring accuracy, in order to reduce contact resistance, needs to strengthen contact area, increases contact pressure.In measuring process, the electric current of primary circuit is sometimes up to 2000 amperes.Therefore, require clamping force reliable and stable, must not break off for some reason, otherwise can cause instantaneous pressure, cause the accident.
For the full-automatic clamping that realizes mutual inductor primary conductive plate with unclamp, multiple clamping scheme is arranged at present, comprise with cylinder directly compressing and use motor leading screw clamping etc.
Summary of the invention
The purpose of the utility model is for the full-automatic clamping that realizes mutual inductor primary conductive plate and unclamps; Provide a kind of clamping force big and constant mutual inductor primary connection clamp device, realize a kind of mutual inductor primary connection clamp device through following measure; Have upper lever 2 and following lever 8; Through the structure that is connected to form similar clamp of bearing pin 3, upper lever 2 connects goes up fixture block 1, and following lever 8 connects fixture block 7 down; Last connecting rod 4 forms hinge with lower link 9 with cylinder rod 5 and is connected, and cylinder rod 5 connects cylinder 6.Under the effect of cylinder 6, make two upper and lower foldings of fixture block.
Above-mentioned fixture block and lever are hinged.
The utlity model has three characteristics: the one, clamping force is big.With the less cylinder 6 of specification, interact through cylinder rod 5 and connecting rod 4, when upright, can produce bigger anchorage force at connecting rod.This is because the anchorage force of two connecting rods and cylinder pulling force form the plane concurrent force system, can be known by equilibrium principle, because angle, less cylinder pulling force can cause bigger link supports power.The right-hand member of upper lever 2 receives the anchorage force that connecting rod makes progress, and the both sides arm of force length of the fulcrum-bearing pin 3 of upper lever 2 is different, and promptly the power arm on right side is longer; The resistance arm in left side is shorter; So obtain reinforcement for the second time, the clamping force on the fixture block is far longer than the cylinder pulling force, guarantees enough clamping forces.The 2nd, clamping force is constant.After last connecting rod 4 was upright, two levers had turned to extreme position, and clamping force and cylinder pulling force have had nothing to do, and the clamping force size depends on the rigidity and the elastic deformation amount of entire mechanism.The 3rd, reliable clamping when cylinder rapid decompression for some reason, still can keep clamping force.When cylinder rod retracted, last connecting rod 4 was upright from tilting to, and this position is that clamping force reaches maximum state.When cylinder rod moved to the right extreme position, the motion of last connecting rod 4 surpassed upright position, and tilted a little in the other direction, made entire mechanism be in steady state (SS).
Description of drawings
Fig. 1 is in the structural representation of clamped condition for device.
Fig. 2 is in the structural representation of releasing orientation for device.
Embodiment
Embodiment 1: seeing figures.1.and.2 is an embodiment of the utility model, a kind of mutual inductor primary connection clamp device, and lever 2 and the structure that be connected to form similar clamp of lever 8 through bearing pin 3, upper lever 2 connect goes up fixture block 1, and following lever 8 connects fixture block 7 down; Last connecting rod 4 is hinged with cylinder rod 5 formation with lower link 9, and cylinder rod 5 connects cylinders 6.
Above-mentioned fixture block and lever are hinged.
When cylinder rod was released, connecting rod tilted, and two fixture blocks open, and unclamp mutual inductor primary conductive plate.When cylinder rod was pulled to left side extreme position, two fixture blocks opened maximum, waited for the entering of mutual inductor primary conductive plate; When cylinder rod is pulled the right extreme position, clamp mutual inductor primary conductive plate, and it is oblique to make connecting rod be in 1 ° of angle lapping of opposite direction, makes clamp device be in steady state (SS).
Claims (2)
1. mutual inductor primary connection clamp device; It is characterized in that upper lever (2) and following lever (8); Through the structure that is connected to form clamp of bearing pin (3), fixture block (1) in upper lever (2) connection, following lever (8) connect fixture block (7) down; Last connecting rod (4) is connected with cylinder rod (5) with lower link (9), and cylinder rod (5) connects cylinder (6).
