[0023] The present invention will now be further described with reference to the accompanying drawings.

[0024] like Figure 1-10As shown, a mobile small transformer high-efficiency assembly mechanism includes a mobile mechanism 1, a core lifting mechanism 8 and an auxiliary assembly mechanism 30. The mobile mechanism 1 is placed on the ground and moves on the ground. The top of the mobile mechanism 1 is installed to a plurality of vertically arranged guide rods 7 by welding, and the plurality of guide rods 7 are arranged at equal intervals. The core lifting mechanism 8 is arranged on the plurality of guide rods 7. The core lifting mechanism 8 is used to lift the entire core upward. The core laminations manually removed are placed on the core lifting mechanism 8 for lifting, so that the top of the phase column of the core can be wound with windings. After the assembly is completed, the core lifting mechanism 8 is lowered to place the core laminations below the core lifting mechanism 8 and the core lifting mechanism 8 is lower than the top of the phase column. The staff clamps the core laminations on the top of the core, and then installs the iron yoke to clamp the core, which is convenient for disassembly and assembly (manual assembly). A clamping assembly 25 is installed on the inner side of the core lifting mechanism 8. When the core is lifted, the core is clamped by the clamping assembly 25 to prevent the core from shaking. An auxiliary assembly mechanism 30 is provided below the core lifting mechanism 8. The winding is auxiliary assembled by the auxiliary assembly mechanism 30, that is, when the core lifting mechanism 8 rises, the top of the phase column Leave an air gap for the winding to extend into, place the winding on the auxiliary assembly mechanism 30, and put the winding on the phase column by moving the auxiliary assembly mechanism 30 downward; when working, move the core lifting mechanism 8 downward and the core lifting mechanism 8 is lower than the top core laminations, remove the core laminations at the top one by one and place them on the core lifting mechanism 8, when the top core laminations are manually removed, the core lifting mechanism 8 rises, so that the top core laminations are located above the core, and then place the winding on the auxiliary assembly mechanism 30, and put the winding on the core by descending the auxiliary assembly mechanism 30 The core lifting mechanism 8 is placed on the phase column, and then the core lifting mechanism 8 is lowered and lower than the top of the phase column. The staff inserts each group of cores (two pieces as a group) into the top of the core, which is convenient for the staff to assemble quickly (convenient to take the core stacking sheets). Then the staff installs the iron yoke and the iron yoke pull rod. At the same time, the core lifting mechanism 8 lifts and supports the core from the inner side of the phase. The core lifting mechanism 8 can lift the iron yoke, and then the core lifting mechanism 8 rises to lift the core, and the transformer box is placed under the core. Then the core lifting mechanism 8 descends to place the core into the transformer box, thus completing the preliminary assembly of the transformer.

[0025] The core lifting mechanism includes a lifting screw 9, a lifting seat 10, a lifting assembly 20 and a jacking assembly 24. A lifting seat 10 is sleeved on each guide rod 7 and is lifted and lowered on the guide rod 7 (a through hole is provided on the lifting seat 10 for the working guide rod 7 to pass through), and multiple lifting seats 10 are connected by a connecting plate 11 (the connecting plate 11 is U-shaped, and the connecting plate is connected to multiple lifting seats 10 by bolts, so that the lifting seat 10 drives the connecting plate 11 to lift and lower), and the tops of the multiple guide rods 7 are fixed to the same U-shaped plate 40 by welding. On the top, a plurality of vertically arranged lifting screw rods 9 are installed between the bottom of the mobile mechanism 1 and the U-shaped plate 40, and a gear is fixed at the bottom of each lifting screw rod 9 by welding. The multiple gears at the bottom of the lifting screw rod 9 form a group, and the multiple gears in the same group are driven by a chain, so that the synchronization of the multiple lifting screw rods 9 is completed. A motor for driving the lifting screw rod 9 to rotate is fixed at the bottom of one of the lifting screw rods 9 by welding, and the motor is buried in the mobile mechanism 1; each lifting screw rod 9 passes through the connecting plate 11 and the lifting screw rod 9 and the connecting plate 11 are screwed together. The lifting and lowering of the connecting plate 11 is realized by rotating the lifting screw 9; the jacking assembly 24 is fixed on the top of the connecting plate 11 by bolt fastening, and a lifting assembly 20 is installed on the jacking assembly 24, and the lifting assembly 20 extends below the top layer of the core. The lifting assembly 20 rises and falls synchronously with the connecting plate 11, so that the core is lifted, and a clamping assembly 25 is arranged on the lifting assembly 20, and the two sides of the core are clamped by the clamping assembly 25 to avoid the core shaking when lifting (the bottom of the top layer of the core is arc-shaped, and it is not correct when lifting). If clamping is performed on both sides, the core will shake. A sliding strut 29 is provided between the lifting assembly 20 and the connecting plate 11, and the lifting assembly 20 is supported by the strut 29. When working, when the core needs to be supported, the lifting assembly 20 is lifted to the bottom of the core by the lifting assembly 24, and the core is lifted by the rising of the connecting plate 11. When the core disc is placed, the lifting assembly is returned to its position by the lifting assembly 24, and the core disc is placed on the lifting assembly and the core disc is located below the clamping assembly 25.

[0026] There are two groups of lifting assemblies 20, and the two groups of lifting assemblies 20 are arranged opposite to each other on the left and right sides. Each group of lifting assemblies 20 includes a plurality of lifting plates 21 and lifting plates 22 arranged side by side in the longitudinal direction, wherein the bottom of the lifting plate 22 is hinged to the lifting plate 21, and a torsion spring is fixed by welding at the hinge of the lifting plate 22 and the lifting plate 21, and the lifting plate 22 is swung into a horizontal state by the torsion spring, and a through hole is opened in the lifting plate 21, and a limit plate 23 is inserted into the through hole, and the limit plate 23 passes through the lifting plate 21, and the top of the limit plate 23 on the same side is fixed to the same flat plate by welding, and a spring is fixed by welding between the top of the lifting plate 21 and the limit plate 23, and the spring is realized The limit plate 23 is pressed downward, and when the limit plate 23 drops, the inner side surface of the limit plate 23 abuts against the outer end surface of the lifting plate 22, thus limiting the lifting plate 22 from swinging downward. When the iron core needs to be lifted, the spring presses the limit plate 23 downward, so that the outer end surface of the lifting plate 22 abuts against the inner side surface of the limit plate 23, so that the lifting plate 22 can only swing upward and cannot swing downward, so that the lifting plate 22 can lift the iron core and the iron core disc. When the iron core is placed in the transformer box, due to the relatively small gap between the iron core and the transformer box, if the lifting plate 22 is set horizontally, it is impossible to take the lifting plate 22 out of the box, so the horizontal lifting The plate, in this way, moves the limit plate 23 upward, and the outer end of the lifting plate 22 loses the limit plate 23, so that the lifting plate 22 swings downward from the vertical state, so that the connecting plate 11 rises, and the lifting plate 22 leaves the box. When the lifting plate 22 leaves the box, the flat plate is released, so that the limit plate 23 drops, and the limit plate 23 is pressed against the outer side of the lifting plate 22, so that the lifting plate 22 is restricted from swinging downward, and the next lifting can be performed; a transverse slide groove 12 is fixed at the bottom of the connecting plate 11 by welding, and the slider 13 is embedded in the slide groove 12 for sliding, and a lifting plate 21 is fixed at one end of the slider 13 by welding, and the outer wall of the lifting plate 21 is fastened by bolts. A support seat 14 is installed, and sliding seats 15 that slide with the connecting plate 11 are arranged on both sides of the slide groove 12 and at the bottom of the connecting plate 11 (that is, a guide groove for the sliding seat 15 to be embedded is opened at the bottom of the connecting plate 11 and the sliding seat 5 slides in the guide groove, and the guide groove is arranged horizontally). A support rod 29 is hinged between the sliding seat 15 and the support seat 14, and a locking assembly 16 for preventing retreat is arranged on the sliding seat 15. The lifting plate 21 is supported by the support rod 29 to prevent the lifting plate 21 from deforming outward. The jacking assembly 24 is an electric push rod, and the push rod of the electric push rod is fixed to the lifting plate 21 by bolts, and the lifting plate 21 is moved inward by the jacking assembly 24.

[0027] The locking assembly 16 includes a pawl 17, an electromagnetic sheet 18 and an oblique tooth 19. Electromagnetic sheets 18 of the same length as the slide slot 12 are fixed on both sides above the slide slot 12 by pre-embedded means. The electromagnetic sheet 18 is located above the guide slot. When the electromagnetic sheet is energized, the electromagnetic sheet 18 has a magnetic core. A pawl 17 is hinged at the tail of the slider 13. A pull rope is installed between the pawl 17 and the slider 13. The pull rope is used to prevent the pawl from swinging downward and disengaging from the magnetism of the electromagnetic sheet 18. A plurality of oblique teeth 19 with equal spacing are provided in each guide slot. The pawl 17 is attracted by the electromagnetic sheet 18 to swing upward and extend into the oblique tooth 19. The plurality of electromagnetic sheets 18 are connected to the power switch through a guide. When the lifting assembly 24 retreats, the electromagnetic sheet 18 is manually powered off. At other times, the electromagnetic sheet 18 is fully powered.

A hydraulic cylinder is provided, and the lifting of the support rod 32 is achieved by the extension and retraction of the hydraulic cylinder. When the hydraulic cylinder retracts, the support rod 32 is lifted inward. Multiple parallel windings are placed on the support rod 32. By adjusting the position of the windings relative to the phase column, a rotating shaft 37 driven by a motor is installed on the lifting plate 21 through a bearing. The lifting component 39 is a rack 38 and a gear. Multiple gears are fixed on the rotating shaft 37 by welding. A vertically arranged rack 38 is fixed on the back of the lifting rod 31 by welding, and the rack 38 is meshed with the gear.
