Description

Technical Field

[0001] The invention relates to the technical field of welding displacement equipment, in particular to a special displacement device for welding crawler crane structural parts. Background Art

[0002] Crawler crane is a kind of heavy lifting equipment widely used in construction, ports, mines and other fields. In large-scale construction projects, it is used to lift heavy construction materials such as steel structures and prefabricated concrete parts; in ports, it is used to load and unload large cargo and containers; in mines, it is used to transport heavy ore equipment, etc.

[0003] When the crane structure is being welded, it needs to be clamped on a displacement device to keep it stable during welding. When the truss structure on the crane is clamped, the existing devices generally clamp the truss on both sides through two clamps that are controlled by bolts to move relative to each other. Since there are many gaps and cylindrical structures on the truss structure, the contact points and contact areas with the clamps are relatively small when clamped, which can easily cause the truss to slide and displace under the inertia of rotation during rotational welding, affecting the welding efficiency.

[0017] The present invention has the following beneficial effects:

[0018] 1. In the present invention, when the structural member is placed on the workbench, the structural member will press the sliding frame downward, and when the sliding frame is pressed downward, the short rods on the bow cylinder will be pressed downward through the arc groove, and when the multiple short rods are pressed downward, the bow cylinder will be driven to move downward synchronously. At this time, when the bow cylinder moves downward, the right-angle spring plate will move downward synchronously with the bow cylinder under the internal elastic force, and when the bow cylinder moves downward, the serrated ring will drive the multiple right-angle rods to slide downward in the Z-shaped groove on the inner wall of the circular hole, and then the sliding frame is When the structural part continues to move downward under the downward pressure, the short rod on the bow cylinder will drive the bow cylinder to rotate along the arc line of the arc groove under the guidance of the arc groove. When the bow cylinder rotates, it will drive the serrated ring to rotate through multiple auxiliary teeth in the annular groove at the bottom of the bow cylinder. At this time, the serrated ring will rotate to the corner of the Z-shaped groove to prevent the bow cylinder from resetting. Then, when the bow cylinder moves downward, it will drive multiple C-shaped frames to move downward synchronously through the inner shaft. When the C-shaped frame moves downward, the arc plate will be on the side wall of the gap in the welded structure, and at the same time When the sliding plate is moved outward, the sliding plate is pushed away from the workbench and the sliding plate is moved back and forth, thereby increasing the stability of the sliding plate and the welding efficiency.

[0019] 2. According to the present invention, when the middle rod drives the sliding frame 2 to slide, part of the position on the structural member will enter the interior of the sliding frame 2, and then when the sliding frame 2 continues to move, the movement of the sliding frame 2 will squeeze the structural member. After being squeezed, the structural member will squeeze the arc-shaped elastic plate 2 to make it move in the direction of the inner axis. When the arc-shaped elastic plate 2 moves backward, it will pull one end of the arc-shaped elastic plate 1 to move backward. When the arc-shaped elastic plate 1 is pulled by the arc-shaped elastic plate 2, it will drive the flexible layer to squeeze the bottom of the structural member entering the interior of the sliding frame 2. At the same time, when the arc-shaped elastic plate 2 slides, it will be squeezed by the inclined block on the top inner wall of the sliding frame 2, thereby driving the flexible layer 2 to cover and squeeze the structural member. The covering and squeezing of the flexible layer and the flexible layer 2 can further enhance the stability of the structural member during rotation welding, and at the same time, it can also reduce the situation where the structural member falls off when it rotates to the bottom, thereby improving the welding efficiency.

[0020] When the sliding frame is pulled by the middle rod to slide, the sliding of the sliding frame will drive the hollow plate to slide synchronously. When the hollow plate is sliding, the threaded rod will rotate under the sliding of the inserted rod inside the hollow plate. When the threaded rod rotates, it will drive the obtuse plate to rotate synchronously. When the obtuse plate rotates, it will drive the square frame to rotate through the spherical rod and slide downward on the surface of the long rod. When the square frame slides downward, the roller at the bottom and the square frame will pass through the workbench and contact the top outer wall of the fixed frame. When the roller on the square frame contacts the top outer wall of the fixed frame, it can provide a certain supporting force for the sliding frame, reduce the shaking of the structural member when it rotates and is in an inclined state, reduce the shaking of the structural member during welding, and cause defects such as corrugations and pores in the weld during welding. At the same time, when the roller contacts the top of the fixed frame, it can provide a certain sliding force during the rotation of the workbench, which can enhance the stability of the rotation of the workbench and improve the welding quality.

[0021] When the semicircular plate is pushed by the auxiliary plate, it will rotate on the surface of the sliding frame, and when the semicircular plate is rotated, it will generate an inward driving force on the structural member. At the same time, the rotation of the semicircular plate can also block the opening of the sliding frame 2, thereby reducing the situation that the structural member tilts and slides inside the sliding frame 2 under its own gravity when rotating. At the same time, when the semicircular plate rotates to push the structural member and plays a certain blocking role at the opening of the sliding frame 2, it can reduce the situation that the structural member is separated from the sliding frame 2 when it rotates to a more inclined angle, reduce the deformation or deviation of welding caused by the slipping of the structural member, and improve the stability of the structural member during welding.

[0022] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

After being squeezed, the sliding plate 704 will slide inside the long groove. When the sliding plate 704 slides, it will push the semicircular plate 705 through the auxiliary plate.

[0047] When in use, first place the structural part to be welded on the top of the workbench 201, then connect the external clamp to the workbench 201 through bolts and fix the structural part by adjusting the external clamp, then start the electric frame 101 and the motor 103 as needed during welding, the electric frame 101 will drive the structural part to rotate in a circle through the rotating frame 102 when working, and then when the motor 103 is working, it will drive the workbench 201 to rotate through the engagement of the gear and the gear ring, and when the workbench 201 rotates, it will drive the structural part to rotate horizontally, so that the purpose of welding can be achieved.

[0048] When the structural part is placed on the workbench 201, the structural part will squeeze the sliding frame 203 downward, and when the sliding frame 203 is squeezed downward, the short rods on the bow tube 205 will be squeezed downward through the arc groove 204. When multiple short rods are squeezed downward, the bow tube 205 will be driven to move downward synchronously. At this time, when the bow tube 205 moves downward, the right-angle spring plate 503 will move downward synchronously with the bow tube 205 under the internal elastic force. When the bow tube 205 moves downward, it will drive multiple right-angle rods 303 to slide downward in the Z-shaped groove on the inner wall of the circular hole through the sawtooth ring 302, and then the sliding frame 203 is When the structural member continues to move downward under the downward pressure, the short rod on the bow cylinder 205 will drive the bow cylinder 205 to rotate along the arc line of the arc groove 204 under the guidance of the arc groove 204. When the bow cylinder 205 rotates, it will drive the serrated ring 302 to rotate through the multiple auxiliary teeth in the annular groove at the bottom of the bow cylinder 205. At this time, the serrated ring 302 will rotate to the corner of the Z-shaped groove to prevent the bow cylinder 205 from resetting. Subsequently, when the bow cylinder 205 moves downward, it will drive multiple C-shaped frames 401 to move downward synchronously through the inner shaft 301. When the C-shaped frame 401 moves downward, the arc plate 501 will be in a welded state. At the same time, when the bow cylinder 205 rotates, the rotation of the bow cylinder 205 will squeeze the right-angle spring plate 503 through the serrated structure on the top. After being squeezed by the serrated structure, the right-angle spring plate 503 will drive the sliding sleeve 502 to move upward. When the sliding sleeve 502 moves upward, it will push the rotating plate 402 to rotate through the arc plate 501. When the rotating plate 402 rotates, it will drive the arc plate 501 to form an outward expansion state. Then, the expanded arc plate 501 will be inserted into the gap on the structural member, and exert a certain downward pressure on the structural member inside the gap of the structural member. Pressure, at the same time, when the rotating plate 402 rotates, the rotation of the rotating plate 402 will pull the sliding frame 2 601 to slide outward synchronously through the middle rod 403. When the sliding frame 2 601 moves outward, it will produce an outward pushing effect on the structural parts. Combined with the downward pressure generated by the arc plate 501 on the structural parts, the stability of the structural parts on the workbench 201 can be enhanced when the structural parts rotate with the workbench 201, and the sliding or displacement phenomenon caused by the inertia force generated during vibration or rotation during welding can be reduced, so as to improve the stability of the structural parts during welding and improve the welding efficiency.

[0049] When the middle rod 403 drives the sliding frame 2 601 to slide, part of the position on the structural member will enter the interior of the sliding frame 2 601. Then, when the sliding frame 2 601 continues to move, the movement of the sliding frame 2 601 will squeeze the structural member. After being squeezed, the structural member will squeeze the arc-shaped elastic plate 2 603 to move toward the direction of the inner shaft 301. When the arc-shaped elastic plate 2 603 moves backward, it will pull one end of the arc-shaped elastic plate 1 602 to move backward. When the arc-shaped elastic plate 1 602 is squeezed by the arc-shaped elastic plate 2 When the plate 2 603 is pulled, the flexible layer will be driven to squeeze the bottom of the structural part that enters the sliding frame 2 601. At the same time, when the arc-shaped elastic plate 2 603 slides, it will be squeezed by the inclined block on the top inner wall of the sliding frame 2 601, thereby driving the flexible layer 2 to cover and squeeze the structural part. The covering and squeezing of the flexible layer and the flexible layer 2 can further enhance the stability of the structural part during rotational welding, and can also reduce the possibility of the structural part falling off when it rotates to the bottom, thereby improving the welding efficiency.

[0050] When the sliding frame 601 slides due to the pulling of the middle rod 403, the sliding of the sliding frame 601 will drive the hollow plate 604 to slide synchronously. When the hollow plate 604 slides, the threaded rod 701 will rotate under the sliding of the inserted rod inside the hollow plate 604. When the threaded rod 701 rotates, it will drive the obtuse angle plate 702 to rotate synchronously. When the obtuse angle plate 702 rotates, it will drive the square frame 801 to rotate through the spherical rod 803 and will also slide downward on the surface of the long rod 802. When the square frame 801 slides downward, the roller at the bottom and the square frame 801 will pass through the workbench 2. 01 and contacts with the top outer wall of the fixed frame 104. When the roller on the square frame 801 contacts with the top outer wall of the fixed frame 104, it can provide a certain supporting force for the sliding frame 203, reduce the shaking when the structural parts rotate and are in a tilted state, and reduce the shaking of the structural parts during welding, which leads to defects such as ripples and pores in the weld during welding. At the same time, when the roller contacts with the top of the fixed frame 104, it can provide a certain sliding force during the rotation of the workbench 201, which can enhance the rotation stability of the workbench 201 and improve the welding quality.

[0051] When the threaded rod 701 drives the obtuse-angled plate 702 to rotate, the rotation of the obtuse-angled plate 702 will squeeze the inclined surface on the sliding plate 704 through the inclined ring on the side wall. After being squeezed, the sliding plate 704 will slide inside the long groove. When the sliding plate 704 slides, it will push the semicircular plate 705 through the auxiliary plate. When the semicircular plate 705 is pushed by the auxiliary plate, it will rotate on the surface of the sliding frame 203. When the semicircular plate 705 rotates, it will generate an inward driving force on the structural member. At the same time, the rotation of the semicircular plate 705 The movement can also block the opening of the sliding frame 601, thereby reducing the possibility that the structural member will tilt and slide inside the sliding frame 601 under its own gravity when rotating. At the same time, when the semicircular plate 705 rotates to push the structural member and relatively plays a certain blocking role at the opening of the sliding frame 601, it can reduce the possibility that the structural member will separate from the sliding frame 601 when rotating to a more inclined angle, reduce deformation or deviation in welding due to slipping of the structural member, and improve the stability of the structural member during welding.
