DETAILED DESCRIPTION

[0053] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0054] Example 1: Reference Figures 1-6 , an intelligent welding device for installing a fixed discharge hopper on the silo roof, comprising an equipment box 5, a silo roof discharge barrel 3 and a plurality of discharge inclined buckets 4 to be welded. The plurality of discharge inclined buckets 4 are welded to the outer side of the silo roof discharge barrel 3 using the welding device. After the plurality of discharge inclined buckets 4 are all welded, the silo roof fixed discharge hopper is formed, as shown in the attached manual. Figure 2 shown.

[0055] The welding device also includes:

[0056] The support column 6 is fixedly connected to the upper part of the equipment box 5. The support column 6 is provided with a positioning top cover 2, and the positioning top cover 2 is provided with a positioning component for positioning the bin top discharge barrel 3;

[0057] The positioning assembly includes a supporting ring 8 fixedly mounted on the lower portion of the positioning top cover 2 for supporting the silo top discharge barrel 3 , and a plurality of adsorption mechanisms for reinforcing the silo top discharge barrel 3 are provided on the supporting ring 8 .

[0058] The adsorption mechanism includes a mounting frame 10 fixedly mounted on the outside of the supporting ring 8, and the mounting frame 10 is located on the outside of the silo top discharge barrel 3. A magnetic plate 11 is fixedly mounted on the mounting frame 10 through an elastic rod. A magnetic frame 12 that cooperates with the magnetic plate 11 is fixedly mounted on the inside of the supporting ring 8, and the magnetic frame 12 is located on the inside of the silo top discharge barrel 3, and the magnetic frame 12 is in contact with the inner wall of the silo top discharge barrel 3;

[0059] When welding the top discharge barrel 3 of the silo, the top discharge barrel 3 is first put on the positioning top cover 2 from top to bottom, and the bottom of the top discharge barrel 3 is placed on the supporting ring 8, and then multiple magnetic frames 12 and multiple magnetic plates 11 are started to make the two generate magnetism and attract each other. At this time, the magnetic plate 11 will move and fit to the outer wall of the top discharge barrel 3 under the action of magnetic attraction, and adsorb with the magnetic frame 12 inside the top discharge barrel 3. Under the adsorption action, the barrel wall of the top discharge barrel 3 can be adsorbed and clamped, so that the top discharge barrel 3 can be adsorbed and positioned, which can effectively improve the positioning stability of the top discharge barrel 3 and prevent it from shaking during welding.

[0060] The lifting unit is arranged on the support column 6. The lifting unit is used to realize the positioning and height adjustment of the unloading inclined bucket 4 to be welded, so that the unloading inclined bucket 4 can be quickly moved to the height position to be welded on the unloading barrel 3 on the top of the silo, thereby quickly realizing the welding of multiple unloading inclined buckets 4, and the welding process will not be restricted by height, and welding is more convenient.

[0061] The welding control unit is arranged on the fixed support ring 13, and is used to adjust the angular position of the unloading inclined bucket 4 to be welded, so that the unloading inclined bucket 4 can be accurately rotated to the position to be welded on the silo top unloading barrel 3, thereby improving the accuracy of welding. At the same time, the unloading inclined bucket 4 can be efficiently and stably automated with arc welding, and the welding effect is better.

[0062] A support base 1 is provided at the bottom of the equipment box 5 for support, and a control panel is provided on the outside of the equipment box 5 for controlling the opening and closing and operating status of the positioning component, the servo motor 15, the lifting unit, and the welding control unit.

[0063] The servo motor 15 is arranged in the equipment box 5, and a driving roller 16 for driving is provided on the driving end of the servo motor 15. When the servo motor 15 is started, it will drive the driving roller 16 to rotate. The operating state of the servo motor 15 can be controlled through the control panel, thereby controlling the rotation speed and rotation direction of the driving roller 16.

[0064] Example 2: Reference Figure 1-Figure 3 as well as Figure 7-11 The technical solution of this embodiment is different from that of the first embodiment in that the lifting unit includes a clamping assembly and a lifting assembly. The lifting assembly is used to adjust the welding height position of the unloading inclined bucket 4. A fixed support ring 13 for support is provided in the lifting assembly. The clamping assembly is provided on the fixed support ring 13 to achieve clamping and positioning of the unloading inclined bucket 4 to be welded.

[0065] The clamping assembly includes a positioning frame 14 fixedly mounted on a fixed support ring 13 for placing the unloading oblique bucket 4. Two electric telescopic rods 32 are fixedly mounted on the positioning frame 14. The driving ends of the two electric telescopic rods 32 are fixedly mounted with positioning clamping plates 33 for clamping the sides of the unloading oblique bucket 4. Two telescopic connecting rods are fixedly mounted between the two positioning clamping plates 33 and the positioning frame 14.

[0066] When welding the unloading oblique bucket 4, first make the fixed support ring 13 at the lowest point, so that the fixed support ring 13 is in a suitable installation position, and then the unloading oblique bucket 4 to be welded is clamped and placed in the positioning frame 14, and then the two electric telescopic rods 32 are started to drive the two positioning clamping plates 33 to move. The two positioning clamping plates 33 will clamp and fix the unloading oblique bucket 4 so that it will not separate from the positioning frame 14, thereby ensuring its stability during welding. At this time, the unloading oblique bucket 4 will rise and fall with the rise and fall of the fixed support ring 13 and the positioning frame 14.

[0067] In a further embodiment, the lifting assembly includes a linkage roller 20 rotatably mounted in the equipment box 5, and a linkage mechanism is installed between the linkage roller 20 and the drive roller 16, the linkage mechanism includes a bevel gear 2 19 fixedly mounted on the linkage roller 20, and the drive roller 16 is provided with an electric self-locking wheel for automatic locking, and the electric self-locking wheel is fixedly mounted with a bevel gear 18, and the bevel gear 18 is meshed with the bevel gear 2 19;

[0068] When the unloading inclined bucket 4 is positioned, the servo motor 15 can be started to drive the driving roller 16 to rotate forward, and the electric self-locking wheel can be started to lock it with the driving roller 16. That is, when the driving roller 16 rotates forward, it will drive the electric self-locking wheel and the bevel gear 18 to rotate. The rotation of the bevel gear 18 will drive the meshing bevel gear 2 19 to rotate, and then drive the linkage roller 20 to rotate together.

[0069] The electric self-locking wheel is an existing device, and its specific structure consists of an outer ring, multiple electric push rods and a limit ring, wherein the limit ring is rotatably sleeved on the outside of the driving roller 16, the limit ring is fixed to the outer ring, and multiple electric push rods are arranged inside the outer ring;

[0070] Its working principle is as follows: a plurality of positioning holes that cooperate with it are provided on the driving roller 16. When automatic locking is performed, the electric push rod is started to drive its end to move so that its end is engaged with the positioning hole on the driving roller 16, thus completing self-locking. At this time, the rotation of the driving roller 16 will drive the outer ring as a whole to rotate synchronously through the cooperation of the positioning hole and the electric push rod. Otherwise, it is unlocked, and the rotation of the driving roller 16 will not drive the outer ring to rotate. This part is existing technology and will not be elaborated on here.

[0071] A vertical support frame 22 is fixedly installed in the support column 6, and a lifting slider 26 for lifting and sliding is slidably installed on the vertical support frame 22. A lifting ring frame 17 is fixedly installed on the lifting slider 26 through a linkage slide rod 24, and a lifting slide groove 7 that cooperates with the linkage slide rod 24 is opened on the support column 6;

[0072] The lifting slider 26 can slide vertically on the vertical support frame 22. When the lifting slider 26 slides up and down, it will drive the linkage slide bar 24 to slide up and down in the lifting slide groove 7, and then drive the lifting ring frame 17 to slide up and down.

[0073] A hanging mechanism is installed between the lifting slider 26 and the linkage roller 20. The hanging mechanism includes a winding wheel 21 fixedly mounted on the linkage roller 20, and a traction rope 23 for traction is wound around the winding wheel 21, and the end of the traction rope 23 is fixedly connected to the lifting slider 26. A deflection fixed pulley 25 that cooperates with the traction rope 23 is fixedly mounted in the support column 6, and the deflection fixed pulley 25 is located on the upper part of the vertical support frame 22.

[0074] When the linkage roller 20 rotates, it drives the winding wheel 21 to rotate. When the winding wheel 21 rotates, the traction rope 23 is wound. When the traction rope 23 is wound, its end rises, and the lifting slider 26 is pulled upward with the cooperation of the steering fixed pulley 25, and the lifting slider 26 can be pulled to move upward in the support column 6.

[0075] The fixed support ring 13 is rotatably mounted on the upper part of the lifting ring frame 17. When the lifting slider 26 moves upward, the lifting ring frame 17 can be driven upward through the linkage slide rod 24, thereby driving the fixed support ring 13 to move upward as a whole, thereby driving the unloading inclined bucket 4 that has been positioned on the fixed support ring 13 to move upward, so that the unloading inclined bucket 4 moves up to the height position to be welded on the silo top unloading barrel 3, completing the height adjustment work.

[0076] Example 3: Reference Figure 1-Figure 3 、 Figure 7-Figure 8 as well as Figure 12-15 The technical solution of this embodiment is different from that of the second embodiment in that the welding control unit includes a steering assembly and a welding assembly. The steering assembly is provided with a driving external gear 31 for adjusting the angular position of the unloading inclined bucket 4, and the welding assembly is provided with an arc welding gun 38 for realizing the welding of the unloading inclined bucket 4.

[0077] The steering assembly includes a driven inner gear ring 28 fixedly mounted inside the fixed support ring 13, a one-way bearing 230 is provided on the driving roller 16, and the one-way bearing 230 cooperates with the reverse rotation of the driving roller 16, a driving rotating frame 27 is fixedly mounted on the one-way bearing 230, and a driving outer gear 31 is fixedly mounted on the lower part of the driving rotating frame 27, and the driving outer gear 31 is meshed with the driven inner gear ring 28.

[0078] When the fixed support ring 13 is raised or lowered, the driving roller 16 rotates in the forward direction, that is, the one-way bearing 2 30 does not rotate. The upward movement of the fixed support ring 13 will drive the driven inner gear ring 28 to move upward synchronously. When the fixed support ring 13 moves to the highest position, the driven inner gear ring 28 moves up to the outside of the driving outer gear 31 and engages with the driving outer gear 31.

[0079] When the fixed support ring 13 has finished moving up, the electric self-locking wheel is automatically unlocked, and the servo motor 15 is started to drive the driving roller 16 to rotate in the opposite direction. When the driving roller 16 rotates in the opposite direction, it drives the driving rotating frame 27 to rotate, and then drives the driving outer gear 31 and the driven inner gear ring 28 to rotate in the opposite direction, thereby driving the fixed support ring 13 and the unloading inclined bucket 4 on it to rotate in the opposite direction as a whole;

[0080] When welding the first unloading oblique bucket 4, the steering assembly drives the unloading oblique bucket 4 to rotate in the opposite direction from right to left for nearly one circle to the welding position on the left side closest to the initial upward movement point, and then the welding of the first unloading oblique bucket 4 can be started from the leftmost side, and the welding of subsequent multiple unloading oblique buckets 4 is carried out in sequence, that is, the left side position of the initial upward movement point is the initial welding point, and after welding a circle from left to right, the initial upward movement point is the last welding point, completing the circular surrounding welding from left to right, so that each welding will not be affected by the previous unloading oblique bucket 4, thereby completing the welding of multiple unloading oblique buckets 4 in sequence, and the welding efficiency is higher.

[0081] In a further embodiment, the welding assembly includes a one-way bearing 29 provided on the driving roller 16, and the one-way bearing 29 cooperates with the positive rotation of the driving roller 16, a fixing plate 35 is fixedly mounted on the one-way bearing 29, and a push frame 36 is horizontally slidably mounted on the fixing plate 35 via two sliding rods;

[0082] When the welding position of the unloading inclined bucket 4 is adjusted, the driving roller 16 can be driven by the servo motor 15 to rotate forward, thereby driving the one-way bearing 1 29 to rotate forward (the one-way bearing 2 30 will not rotate at this time). The rotation of the one-way bearing 1 29 will drive the fixed plate 35 to rotate as a whole, and the fixed plate 35 can be driven to move to a position opposite to the unloading inclined bucket 4, so that the unloading inclined bucket 4 and the silo top unloading barrel 3 can be internally welded.

[0083] A lifting carriage 37 is vertically slidably mounted on the push frame 36, and an arc welding gun 38 is set on the lifting carriage 37. Electromagnetic plates 34 are fixedly mounted on the push frame 36 and the fixed plate 35, and the two electromagnetic plates 34 cooperate with each other. Two compression spring rods 39 are fixedly mounted between the fixed plate 35 and the push frame 36. A plurality of welding openings 9 for auxiliary welding are opened on the side of the positioning top cover 2;

[0084] During welding, the two electromagnetic plates 34 can be started. The magnetism and magnetic pole changes of the electromagnetic plates 34 and the action of the two compression spring rods 39 can be used to control the movement of the push frame 36, so that the arc welding gun 38 on the push frame 36 is close to or away from the welding position. The height position of the arc welding gun 38 can be automatically adjusted by the lifting and moving vehicle 37 to achieve welding at different heights, thereby achieving comprehensive welding between the unloading inclined bucket 4 and the silo top unloading barrel 3, with higher welding efficiency and no welding dead angles.

[0085] The specific working principle of this welding device is:

[0086] When welding the unloading inclined bucket 4, first make the fixed support ring 13 at the lowest point, so that the fixed support ring 13 is in a suitable installation position, and then the unloading inclined bucket 4 to be welded is clamped and placed in the positioning frame 14, and then the two electric telescopic rods 32 are started to drive the two positioning clamping plates 33 to move, and the unloading inclined bucket 4 is clamped and fixed by the two positioning clamping plates 33.

[0087] Then the servo motor 15 is started to drive the driving roller 16 to rotate forward. The linkage roller 20 rotates through the cooperation of the linkage mechanism. When the linkage roller 20 rotates, it drives the winding wheel 21 to rotate. The rotation of the winding wheel 21 reels the traction rope 23. The retraction rope 23 pulls the lifting slider 26 with the cooperation of the steering fixed pulley 25 to move it upward in the support column 6.

[0088] When the lifting slider 26 moves upward, the lifting ring frame 17 can be driven upward through the linkage slide rod 24, and then the fixed support ring 13 can be driven upward as a whole, thereby driving the unloading inclined bucket 4 that has been positioned on the fixed support ring 13 to move upward, so that the unloading inclined bucket 4 moves up to the height position to be welded on the silo top unloading barrel 3, completing the height adjustment work.

[0089] The upward movement of the fixed support ring 13 will drive the driven inner gear ring 28 to move upward synchronously. When the fixed support ring 13 moves up to the highest position, the driven inner gear ring 28 will move up to the outside of the driving outer gear 31 and mesh with the driving outer gear 31. Then the steering assembly is started to drive the unloading inclined bucket 4 to rotate in the opposite direction from right to left for nearly one circle to the welding position on the left side closest to the initial upward movement point, that is, the welding of the first unloading inclined bucket 4 starts from the leftmost side, and the positions of the subsequent unloading inclined buckets 4 are arranged in sequence, thereby completing the sequential circular welding of multiple unloading inclined buckets 4 from left to right.

[0090] After the welding position of the unloading inclined bucket 4 is adjusted, the servo motor 15 drives the driving roller 16 to rotate forward, driving the one-way bearing 29 to rotate forward. The rotation of the one-way bearing 29 drives the fixed plate 35 to rotate as a whole, driving the fixed plate 35 and the arc welding gun 38 to move to a position opposite to the unloading inclined bucket 4.
