Description

Technical Field

[0001] The invention relates to the technical field of welding equipment, in particular to welding equipment for crane processing. Background Art

[0002] A crane refers to a multi-action lifting machinery that can lift heavy objects vertically and carry them horizontally within a certain range. During the crane processing and welding process, if the truss, main rod and support rod are assembled by high-strength seamless steel pipes using the traditional point-to-point welding method, the spatial relationship of the welding surface will become extremely complicated. During welding, even tiny defects may lead to the accumulation of metal fatigue. The inclusive node increases the contact surface between the main rod and the support rod, which can effectively eliminate the stress of metal fatigue and make the overall boom stronger.

[0003] However, when welding contained nodes, the curved surface results in limited operating space for the weld position and restricted welding postures of welders, which increases the difficulty of welding. Secondly, due to the special structural form of contained nodes, stress concentration is obvious during welding. Different components contain each other, and welds cross and overlap, making stress distribution complex. Cracks and other defects are easily caused during welding, affecting the bearing capacity of the node. Summary of the invention

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention.

[0042] Both sides of the outer surface of the bidirectional lead screw 32 are spirally connected with a screw sleeve 33, a rotating seat 35 is fixedly installed on the top of the screw sleeve 33, and brackets 36 are fixedly installed on both sides of the rotating seat 35, and one end of the bracket 36 away from the rotating seat 35 is fixedly connected to the screw sleeve 33;

[0043] A gear ring 37 is movably mounted on the surface of the rotating seat 35, and a gear 38 is meshed inside the gear ring 37. The number of gears 38 is three and they are evenly distributed inside the gear ring 37. The gears 38 are movably mounted between the rotating seat 35. A first bevel gear 39 is fixedly mounted on the side of the gear 38 away from the rotating seat 35, and a second bevel gear 310 is meshed on one side of the first bevel gear 39.

[0044] A fixing claw 311 is fixedly installed on one side of the second bevel gear 310, and a mounting plate 317 is movably installed on the side of the second bevel gear 310 away from the fixing claw 311. The mounting plate 317 is fixedly connected to the rotating seat 35. A second fixing plate 312 is fixedly installed on the surface of the rotating seat 35. A third servo motor 313 is fixedly installed on the surface of the second fixing plate 312. The second fixing plate 312 is in movably contact with the base 1, and a middle portion of the second bevel gear 310 is fixedly connected to the output shaft of the third servo motor 313.

[0045] A main rod 314 is disposed on the inner side of the fixing claw 311, a curved surface member 315 is disposed on the outer surface of the main rod 314, and a supporting rod 316 is inserted into the curved surface member 315;

[0046] A slider 34 is fixedly mounted on one side of the screw sleeve 33 , and a slide groove matched with the slider 34 is provided on the inner side of the mounting frame 3 , and the slider 34 is movably mounted on the slide groove.

[0047] Specifically, when in use, the user first needs to clamp the main rod 314 with the half gear ring 25, then insert the fastening stud 27 into the fixing piece 26, and tighten the fastening nut 28, so that the fastening nut 28 and the fixing piece 26 are tightly connected, so that the two half gear rings 25 complete the clamping of the main rod 314 and form a complete gear ring. At the same time, ensure that the half gear ring 25 is in the position of dividing the main rod 314 into three equal parts, so as to ensure the stability of the main rod 314 during lifting;

[0048] After the main rod 314 is clamped by the half gear ring 25, it is necessary to start the first servo motor 22 to drive the tightening wheel 23 to rotate, tighten the sling 24, so as to lift the main rod 314, and start the driving mechanism to make the first slide 2 drive the main rod 314 to move, and then move the main rod 314 to the top of the correction piece 210, and then start the first servo motor 22 again to make the tightening wheel 23 rotate, release the sling 24, so that the main rod 314 falls into the correction piece 210, and make the half gear ring 25 contact with the correction piece 210, so as to complete the positioning of the main rod 314, and at the same time ensure the lifting state of the main rod 314 by the half gear ring 25;

[0049] When the main rod 314 is positioned, the second servo motor 31 needs to be started to drive the bidirectional lead screw 32 to rotate, so that the bidirectional lead screw 32 drives the screw sleeve 33 to move, and the screw sleeve 33 can drive the rotating seat 35 to move, so that the rotating seat 35 moves to a position close to the correction member 210, and then the third servo motor 313 is started to drive a second bevel gear 310 to rotate, and under the cooperation of the first bevel gear 39 and the gear 38, the gear ring 37 can be rotated, so that the three second bevel gears 310 rotate together, and then the fixing claw 311 rotates, and the main rod 314 is clamped to complete the fixing of the main rod 314;

[0050] Compared with the traditional clamping method, after hoisting, the main rod is clamped by a steel frame. However, since the main rod is made of metal and has a large volume, it is heavy, which easily causes wear on different parts of the clamping mechanism. Long-term use easily makes it difficult to balance the main rod during welding, affecting the welding accuracy. The present invention maintains the hoisting state so that the main rod 314 and the correction piece 210 are in a semi-suspended state, and uses the sling 24 to share part of the gravity of the main rod 314, so that the correction piece 210 does not bear the entire weight of the second bevel gear 310. With the automatic clamping and fixing of the fixing claw 311, the main rod 314 can be fixed, and the load borne by the clamping assembly can be reduced, thereby increasing its service life.

[0051] Furthermore, in order to ensure the stability of the truss and the uniform distribution of stress, the curved surface member 315 and the support rod 316 are usually welded in the middle of the main rod. First, the curved surface member 315 is placed at the welding position on the surface of the main rod 314, that is, the middle of the main rod 314, and then the first hydraulic cylinder 212 is started to drive the positioning member 213 to move downward to fix the curved surface member 315 and ensure the stability of the curved surface member 315.

[0052] It should be noted that before this, the second slide 211 needs to be located in the middle of the two first slides 2 and fixed by studs so that the second slide 211 can move with the first slide 2, thereby ensuring that after the main rod 314 is positioned, the first hydraulic cylinder 212 is directly above the curved part 315, which is convenient for fixing the curved part 315 and can correct the curved part 315 to avoid the alignment offset of the curved part 315, further improving the welding accuracy.

[0053] Example 2: Please refer to Figure 1 and Figure 6 The adjustment assembly includes a third fixing plate 4, the number of the third fixing plates 4 is two, and they are fixedly mounted on both sides of the upper surface of the base 1, a second hydraulic cylinder 41 is fixedly mounted on the third fixing plate 4, a connecting plate 42 is fixedly mounted on the output shaft of the second hydraulic cylinder 41, and the two second hydraulic cylinders 41 are fixedly connected through the connecting plate 42;

[0054] Racks 43 are fixedly mounted on both ends of the connecting plate 42. The racks 43 are located below the half gear ring 25 and mesh with the half gear ring 25.

[0055] A load-bearing member 45 is fixedly mounted in the middle of the connecting plate 42, and the top of the load-bearing member 45 is lower than the bottom of the main rod 314;

[0056] Support blocks 44 are fixedly installed on both sides of the bottom of the connecting plate 42. The support block 44 is T-shaped. Travel grooves 46 adapted to the support block 44 are opened on both sides of the upper surface of the base 1, and the support block 44 is movably installed in the travel groove 46.

[0057] On the basis of Example 1, when the main rod 314 is positioned so that the main rod 314 is in a semi-suspended state, it is necessary to ensure that the half gear ring 25 is above the rack 43 and meshes with it, and bears part of the weight to avoid the problem of easy deviation during driving;

[0058] When welding the curved surface member 315, after the curved surface member 315 is fixed by the positioning member 213, it is necessary to first weld both sides of the curved surface member 315. Figure 6 At a in the middle, after the curved surface part 315a is welded, the lower side of the curved surface part 315 needs to be welded, that is, Figure 6 The welding position at b is at the bottom. The traditional welding method can only be overhead welding, which is manual welding and has a low welding efficiency. If the molten metal cannot be pushed up, it will sag, causing welding defects.

[0059] The present invention starts the third servo motor 313 to release the clamping of the fixed claw 311 on the main rod 314, starts the first hydraulic cylinder 212, releases the positioning of the positioning member 213 on the curved surface member 315, and then starts the second hydraulic cylinder 41 to drive the connecting plate 42 to move, thereby moving the rack 43, and then driving the half gear ring 25 to rotate 180 degrees, so that the welding position at b faces upward, which is convenient for welding, and avoids the overhead welding method, thereby improving the welding efficiency;

[0060] Furthermore, when the welding position at b is facing upward, the curved member 315 is located below the main rod 314. At this time, the weight of the curved member 315 is only supported by the welding position at a, which may easily cause the welding position at a to be subjected to excessive stress and produce cracks. The present invention sets a load-bearing member 45 in the middle of the connecting plate 42. When the rack 43 moves, it will drive the load-bearing member 45 to move, so that after the welding position at b is adjusted, the load-bearing member 45 is just below the curved member 315, thereby supporting the curved member 315 and improving the welding effect.

[0061] Example 3: Please refer to Figure 1 and Figure 8 The balancing assembly includes a hinge 5 fixedly mounted on the upper surface of the base 1, a support 51 is fixedly mounted on one end of the hinge 5 away from the base 1, and a round block 52 is fixedly mounted on one end of the support 51 away from the hinge 5;

[0062] A balancing spring 53 is sleeved on the outer peripheral side of the pillar 51, a balancing frame 54 is movably mounted on the outer surface of the pillar 51, a first tightening hoop 55 is movably mounted on one end of the balancing frame 54 away from the pillar 51, and a second tightening hoop 57 is arranged on the side of the first tightening hoop 55 away from the balancing frame 54;

[0063] The first tightening hoop 55 and the second tightening hoop 57 are both provided with threaded holes, in which tightening bolts 56 are threadedly connected, and the first tightening hoop 55 and the second tightening hoop 57 are fixedly connected by the tightening bolts 56;

[0064] The support rod 316 is located inside the first tight hoop 55 and the second tight hoop 57, and the distance between the support rods 316 on both sides is greater than the length of the first tight hoop 55 and the second tight hoop 57;

[0065] The diameter of the round block 52 is greater than the diameter of the support column 51 . One end of the balance spring 53 is fixedly connected to the hinge 5 , and the other end is fixedly connected to the balance frame 54 .

[0066] On the basis of Example 2, after the curved surface part 315 is welded, the support rod 316 needs to be inserted into the curved surface part 315 to complete the welding between the curved surface part 315 and the support rod 316. When welding the curved surface part 315 and the support rod 316, the curved surface part 315 needs to be reset first, that is, the curved surface part 315 is placed above the main rod 314, and then welding is performed. However, during the welding process, the curved surface of the curved surface part 315 results in limited operating space for the weld position, and the welder's welding posture is restricted, which increases the difficulty of welding and often encounters welding dead angles. The most common problem of welding dead angles is that it is difficult to make the weldment fully contact with the welding rod, resulting in difficulty in welding the weld, which affects the welding effect.

[0067] In the present invention, when welding the curved surface member 315 and the support rod 316, the easy-to-weld position of the support rod 316 can be welded first. After the welding is completed, the initial fixation between the curved surface member 315 and the support rod 316 can be ensured. Then, the second hydraulic cylinder 41 needs to be started to drive the curved surface member 315 to rotate again, so as to adjust the welding position of the support rod 316 with poor accessibility, thereby reducing the difficulty of welding.

[0068] When the curved member 315 rotates, the support rod 316 will also rotate accordingly. When the support rod 316 leaves the main rod 314 due to the rotation, most of the weight of the support rod 316 will be borne by the weld between the curved member 315 and the support rod 316, which may easily cause cracks in the weld due to excessive stress. In the present invention, before the curved member 315 rotates, the first clamp 55 and the second clamp 57 can be fixedly connected by tightening bolts 56 to surround the support rod 316. Afterwards, the weight of the support rod 316 will be shared by the tension and compression of the balance spring 53, thereby avoiding the influence of excessive stress on the weld between the curved member 315 and the support rod 316, which is similar to the principle of a spring balance cylinder.

[0069] It should be noted that for welding in easy-to-weld positions, the support of the first tight hoop 55 and the second tight hoop 57 is not required. At this time, the weight of the support rod 316 will be borne by the main rod 314, and the interference of the first tight hoop 55 and the second tight hoop 57 on the welder can be avoided. Only when adjusting the dead corners and difficult-to-weld places of the support rod 316, the first tight hoop 55 and the second tight hoop 57 are used, and it should be noted that the adjustment angle is easily affected by the first tight hoop 55 and the second tight hoop 57. For specific operations, the selection of the balancing component can be carried out according to the actual situation.

[0070] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
