Description

Technical Field

The rotation of the sleeve shaft 202 drives the cam 207 to rotate. The rotation of the cam 207 will push the second push-pull rod 209 outward. The second push-pull rod 209 moves outward to push the arc clamping plate 2010 to move toward the inner wall of the installation groove 2011, thereby increasing the friction between the arc clamping plate 2010 and the inner wall of the installation groove 2011, thereby achieving the purpose of fixing the rotating shaft 101.

[0082] When the device is fixing the inner wall of the transformer coil, it can play a buffering role, thereby ensuring the fixing quality and fixing efficiency of the device on the transformer coil.

[0083] Example 1

[0084] During operation, the piston rod of the regulating cylinder 405 is extended to drive the crossbeam 401 to reach the specified height, and the movable frame 4 is pushed to the appropriate position to ensure that the clamping member 3 is located above the transformer coil that needs to be clamped and hoisted. The clamping member 3 is driven to enter the interior of the transformer coil by adjusting the regulating cylinder 405 or the lifting cylinder 301, and the handle 3028 is pulled to drive the first push-pull rod 3026 to move, so that the limit block 3019 at the top of the second sliding rod 3020 cooperates with the second through hole 3027, thereby releasing the restriction of the first push-pull rod 3026 on the limit block 3019, and contracting the piston rod of the lifting cylinder 301 to drive the lifting frame 302 to move upward. When the first support arm 308 and the second support arm 3016 move, the first sliding plate 306 and the mounting frame 303 will slide relative to each other under the dead weight of the mounting frame 303, and the first sliding plate 306 moves upward relative to the mounting frame 303, which will drive the first support arm 308 and the second support arm 3016 to rotate, so that the ends of the first support arm 308 and the second support arm 3016 are against the inner wall of the transformer coil, and the piston rod of the lifting cylinder 301 is continuously retracted, so that the ends of the first support arm 308 and the second support arm 3016 are in close contact with the inner wall of the transformer coil, thereby achieving the purpose of clamping and fixing the transformer coil.

[0085] Example 2

[0086] In order to increase the contact area between the first support arm 308, the second support arm 3016 and the inner wall of the transformer coil and prevent the ends of the first support arm 308 and the second support arm 3016 from point contacting the transformer coil and causing damage to the transformer coil, a third support arm 3021, a fourth support arm 3047, a push plate 307 and a connecting mechanism 305 may also be provided. When the lifting cylinder 301 drives the lifting frame 302 to rise, the bend 3017 on the first pulling rod 3018 will move along the strip through hole 3029 on the lifting rod 3032 until the first spring 3030 is compressed to a suitable position. Continuing to lift the lifting frame 302 will drive the bend 3017 and the first pulling rod 3018 to move upward.

The upward movement of the first rack 3045 will drive the gear 30 39 rotates, the first rack 3045 and the second rack 3044 are meshed with the gear 3039, and the rotation of the gear 3039 will drive the second rack 3044 to move downward. Since the second sliding plate 3011 is connected to the second rack 3044 through the connecting rod 3041, the downward movement of the connecting rod 3041 will drive the second sliding plate 3011 to move downward, and the downward movement of the second sliding plate 3011 will drive the third support arm 3021 and the fourth support arm 3047 to rotate. Since the first sliding plate 306 and the second sliding plate 3011 move in opposite directions at the same time, the first support arm 308, the second support arm 3016, the third support arm 3021 and the fourth support arm 3047 will be driven to rotate at the same time, thereby pushing the push plate 307 outward until the push plate 307 is in close contact with the inner wall of the transformer coil, thereby achieving the purpose of clamping and fixing the transformer coil.

[0087] Example 3

[0088] In order to facilitate the adjustment of the position of the clamping member 3 relative to the movable frame 4, and to facilitate the insertion of the clamping member 3 into the interior of the transformer coil or the placement of the clamped transformer coil at a specified position, an adjustment mechanism 1 may also be provided; when the clamping member 3 or the clamped transformer coil needs to be placed at a specified position, the first winding roller 102 or the second winding roller 108 provided on the vertical poles 403 on both sides of the beam 401 may be rotated, and the first winding roller 102 or the second winding roller 108 may be rotated to achieve the purpose of winding the first steel wire rope 105 or the second steel wire rope 107, and when the first steel wire rope 105 is wound, the second steel wire rope 107 will be unwound, and when the second steel wire rope 107 is wound, the first steel wire rope 105 will be unwound, and in the process of winding and unwinding, the position of the movable trolley 106 on the beam 401 is adjusted, thereby achieving the purpose of adjusting the position of the clamping member 3, and improving the efficiency of loading and unloading the device.

[0089] Example 4

[0090] In order to prevent the first winding roller 102 or the second winding roller 108 from rotating during the transportation process, thereby causing the relative position of the moving trolley 106 to change, the movement of the moving trolley 106 will drive the clamping member 3 to move, thereby failing to ensure the safety of the transformer coil during the transportation process, a locking member 2 is provided, and the setting of the locking member 2 can fix the first winding roller 102 and the second winding roller 108 to prevent the first winding roller 102 or the second winding roller 108 from rotating during the transportation process, and press down one end of the pressure rod 204, and the downward movement of one end of the pressure rod 204 drives the sleeve shaft 202 to rotate around the rotating shaft 101, and the rotation of the sleeve shaft 202 drives the cam 207 to rotate, and the rotation of the cam 207 pushes the second push-pull rod 209 outward. , the second push-pull rod 209 moves outward to push the arc-shaped card plate 2010 toward the inner wall of the installation groove 2011, thereby increasing the friction between the arc-shaped card plate 2010 and the inner wall of the installation groove 2011, and achieving the purpose of fixing the rotating shaft 101, pulling the installation block 2014 to compress the second spring 2013, and matching the limiting column 2015 on the installation block 2014 with the limiting groove 203 on the pressure rod 204. Under the action of the second spring 2013, the upper limit groove 203 end of the pressure rod 204 can always have an upward pulling force, ensuring that the device always provides power for the second push-pull rod 209 to push the arc-shaped card plate 2010 outward, ensuring that the arc-shaped card plate 2010 is always in contact with the inner wall of the installation groove 2011 on the chuck 208, and ensuring the locking quality;

[0091] When contact locking is required, it is only necessary to pull the mounting block 2014 so that the limiting column 2015 on the top of the mounting block 2014 is removed from the limiting groove 203 on the pressing rod 204, and then reset the pressing rod 204.

[0092] Example 5

[0093] In order to ensure the stability of clamping, a buffer mechanism 5 is also provided. When the lifting frame 302 is lifted to drive the bend 3017 and the first pulling rod 3018 to move upward, under the action of the connecting mechanism 305, the first sliding plate 306 and the second sliding plate 3011 move upward and downward at the same time, driving the first support arm 308, the second support arm 3016, the third support arm 3021 and the fourth support arm 3047 to rotate, thereby pushing the push plate 307 outward. Before the push plate 307 contacts the inner wall of the transformer coil, the buffer plate 501 contacts the inner wall of the transformer coil first. If the first pulling rod 3018 is continuously lifted, the push plate 306 will be pushed upward and downward. 307 moves outward, and the outward movement of the push plate 307 will cause the rotating rod 502 to rotate around the rotating shaft 3042, and the rotating arm 503 on the upper rotating rod 502 will drive the connecting shaft 509 to move upward, and the upward movement of the connecting shaft 509 will drive the moving block 508 to move along the mounting hole 506. While the moving block 508 moves, it will also compress the third spring 507. Under the action of the third spring 507, the buffer plate 501 always has an outward thrust, ensuring that the buffer plate 501 is always in close contact with the inner wall of the transformer coil, until the push plate 307 is in close contact with the transformer coil, thereby achieving the purpose of fixing and clamping the transformer coil from the inside.
