The working principle is as follows:
the first step is as follows: aiming at dry-type transformers with different specifications. The number of the connected frame mechanisms 4 can be changed, the frame plate 404 on the frame mechanism 4 on the rear side is pulled towards the direction far away from the frame shaft 401, and is butted to the rear part of the frame plate 404 on the frame mechanism 4 on the front side from the outer side, the plate groove 409 on the frame mechanism 4 on the rear side is correspondingly pushed into the outer side of the connecting plate III 411 on the frame mechanism 4 on the front side, so that the connection between the frame mechanisms 4 is completed, and when the dry-type transformer is hoisted, the frame mechanism 4 cannot fall off due to the trapezoidal structures of the plate groove 409 and the connecting plate III 411, otherwise, the frame mechanism 4 can be conveniently disassembled, so that the butt joint of the frame mechanisms 4 is facilitated, the clamping pieces can be added or disassembled according to different specifications of the dry-type transformer, and the use of the device is more flexible.
The second step is that: the rotating handle 504 is rotated anticlockwise to drive the rotating arms 506 at the front side and the rear side to move, the rotating arms 506 are connected with the vertical rod 510, the moving plates 507 at the two sides are driven by the rotating arms 506 to move along the direction that the frame shaft 401 approaches, the upper iron yoke 108 is gradually clamped, the threaded connection between the threaded column 503 and the threaded hole 502 is realized, the rotating angle of the rotating handle 504 can be effectively controlled, meanwhile, the rotating arms 506 can move up and down along with the rotating handle 504 through the sleeve connection between the rotating arms 506 and the vertical rod 510, the upper position and the lower position of the moving plate 507 cannot be changed, the rotating handle 504 is rotated, the small column 505 and the rotating arms 506 can be driven by the moving plate 507 to tightly and quickly clamp the upper iron yoke 108, the dry-type transformer is convenient to connect, and compared with the step of screwing the screws for multiple times, the operation is convenient to increase, and the installation and disassembly of the dry-type transformer are more convenient and quick.
The third step: the lever 504 is rotated counterclockwise, so that the lever 506 is deviated from the inclined state to the horizontal state, and when a loose state occurs after connection, the moving plate 507 should be moved in the direction away from each other, but at this time, because the angle of the lever 506 is more gentle, the force that can be resolved to the vertical lever 506 by pushing the moving plate 507 in the direction away from each other is reduced, and the force along the lever 506 is increased, so that the lever 504 is hardly pulled by the lever 506 by moving the moving plate 507, the possibility that the moving plate 507 is loosened is reduced, the small column 505 and the lever 506 are in a self-locking state after clamping is completed, and the lifting safety of the device is improved.
The fourth step: in the process of lifting the dry-type transformer, the lifting rope column 701 can enable the lifting column 602 and the clamping seat 601 to move towards the upper side by pulling, so that the telescopic arm 603 deforms, the connection between the telescopic arm 603 and the connecting block 604 and the connection between the connecting block 604 and the arm column 608 are realized, so that the connecting block 604 rotates in the direction away from the clamping seat 601 by taking the arm column 608 as the axial direction, the stabilizing clamp 605 is fixedly connected with the lower surface of the connecting block 604, in the rotating process of the connecting block 604 and the telescopic arm 603, the stabilizing clamp 605 deflects towards the approaching direction, the lower side deflection angle of the stabilizing clamp 605 is larger, the support at the bottom of the upper iron yoke 108 can be automatically reinforced from the bottom, the dry-type transformer can be more stable during lifting, and the transportation stability of the device is improved.
The fifth step: when the moving plate 507 drives the stabilizing clamp 605 and the clamping clamp 606 to clamp the upper iron yoke 108 by rotating the rotating handle 504, due to the connection between the clamping clamp 606 and the moving plate 507, at this time, the clamping clamp 606 moves towards the direction approaching to each other, so as to drive the connecting block 604 to move towards the clamping seat 601, at this time, the clamping seat 601 is pushed by the telescopic arm 603 to move upwards, and meanwhile, the telescopic arm 603 deflects towards the direction away from each other by taking the arm column 608 as an axis, so that the middle part of the telescopic arm 603 slightly moves upwards, thereby avoiding the rotating arm 506 deflecting to the position, so that the self parts of the device cannot be mutually blocked in the adjusting process, the space utilization rate of the device is improved, and the self adaptation degree of the device is increased, so that the device can be better controlled.
And a sixth step: through the design of insulating cylinder mechanism 9, change the operation of original resin integrated into one piece that moulds plastics, but use the split type insulating cylinder mechanism 9 pattern of moulding plastics of separated resin packing, thereby when insulating cylinder mechanism 9 is installed, at first distribute two section of thick bamboo pieces 901 from top to bottom and fill in proper order into letting in hole 610, can make the fine maintenance original state of section of thick bamboo piece 901 not extruded deformation by letting in hole 610 like this, section of thick bamboo piece 901 at both sides all inserts in letting in hole 610 after, rotate semi-ring 904 along outer groove 902, with ball post 905 and pressure hole 903 embedding joint, thereby connect two section of thick bamboo pieces 901, protect insulating cylinder mechanism 9 not receive extrusion and wearing and tearing when installation and butt joint, improve the life of device during the use.
