Description

Technical Field

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

[0002] Chimneys are mostly used in chemical enterprises, petroleum departments, and flammable gas emissions. They are mainly used to convert flammable gases that cannot or cannot be recovered during the production process of petroleum, petrochemical, oil refining, chemical fertilizers, chemical and other enterprises into harmless gases before being discharged into the atmosphere;

[0003] During the erection process of the chimney, it is necessary to cooperate with the tower for auxiliary support to ensure the stability of the chimney during use and avoid the safety problem of tipping over. At the same time, the tower needs to be prefabricated and welded in the factory in the early stage of production. Multiple connecting plates need to be welded on a single column. The cross plate, diagonal rod and column are combined into a complete body through the connecting plates. The connecting plates on the columns are mostly vertically staggered in pairs, which is conducive to the subsequent assembly of the tower. Therefore, welding equipment is required to prefabricate the tower.

[0004] However, most of the current tower welding equipment requires an external clamping mechanism for assistance. The connection plate is pre-fixed on the column by the clamping mechanism and then welded by a welding robot or manually. The single connection plate on the column needs to be fixed and welded separately, which is time-consuming and labor-intensive, and increases the welding cost.

[0005] In addition, since the connecting plates on the tower columns are distributed vertically in pairs, the positions need to be manually debugged repeatedly during a single welding process, which easily leads to welding deviation problems. It is impossible to quickly and synchronously acquire the welding positions of the two corresponding connecting plates, which increases the difficulty of debugging. In addition, it is impossible to synchronously weld the two corresponding connecting plates and columns, which reduces welding efficiency and increases welding difficulty. Summary of the invention

A walking assembly is installed on the rectangular member 14, and a welding unit is added to the walking assembly. The connecting plate member 6 and the column member 2 are welded by the walking assembly and the welding unit.

The two guide rods 16 are correspondingly slid through the crossbeam 10, and a No. 1 limit head for limiting is installed on the top of the two guide rods 16;

[0043] It is worth mentioning that when the connecting plate 6 is welded: a welding mechanism is provided, and the rectangular member 14 and the welding unit are pushed to a predetermined height via the No. 2 electric push rod 11, and then the welding gun 28 is started to weld the connection between the column member 2 and the connecting plate 6, and at the same time, the rotating motor 19 is started, and the synchronous belt 18 is guided by four synchronous wheels 17 to complete the rotation, and then the slide 20 and the welding unit are driven to move. Under the guidance of the synchronous belt 18 and the rectangular track 15, the welding unit moves in a circular shape around the connecting plate 6, so as to complete the rapid welding of the connecting plate 6 and the column member 2, thereby improving the welding efficiency. In order to improve the stability of welding, the welding gun is used. A sensing wheel 27 is added above 28, and the sensing wheel 27 is in rotational contact with the connecting plate 6, so that the welding gun 28 and the connecting plate 6 maintain a stable distance, ensuring the uniformity of welding. In the subsequent movement, the sensing wheel 27 rotates synchronously without interfering with the welding work, and the sensing wheel 27 completes flexible guidance through the flexible spring 24 and the slide bar 23, so that the welding gun 28 can complete adaptive adjustment with the connecting plate 6, and can actively complete flexible avoidance, so that the welding gun 28 and the connecting plate 6 always maintain a certain distance distribution, which provides assistance for the welding work, avoids the collision between the welding gun 28 and the connecting plate 6, and at the same time ensures the quality of welding and reduces the amount of subsequent rework;

[0044] In the embodiment of the present invention, the walking assembly includes synchronous wheels 17 rotatably mounted at the four corners of the rectangular member 14 through a bracket, a synchronous belt 18 is provided on the common transmission sleeve of the four synchronous wheels 17, and a rotating motor 19 for driving is installed on one of the synchronous wheels 17, the synchronous belt 18 is driven by the rotating motor 19 to rotate, and a slide 20 is slidably engaged on the rectangular track 15, and the slide 20 is detachably fixedly connected to one side of the synchronous belt 18;

[0045] Among them, the welding unit includes a sliding frame 21 that is detachably fixed to the lower surface of the sliding member 20, and the top and bottom of the sliding frame 21 are both open in design. A moving block 22 is slidably engaged in the sliding frame 21, and a sliding rod 23 is installed on one side of the moving block 22. The sliding rod 23 is arranged to slide through one side of the sliding frame 21, and a flexible spring 24 is sleeved on the outside of the sliding rod 23. The flexible spring 24 is arranged between the moving block 22 and the sliding frame 21. The elastic coefficient of the flexible spring 24 can be adaptively changed according to the processing environment. The moving block 22 is pushed to move toward the side close to the connecting plate 6 by the flexible spring 24, and a vertical arm 25 is installed at the bottom of the moving block 22. A connecting rod 26 is installed on the side of the vertical arm 25 facing the connecting plate 6, and a sensing wheel 27 is installed at the front end of the connecting rod 26 through a bracket. The sensing wheel 27 is in close contact with the connecting plate 6, and a welding gun 28 is detachably installed at the bottom of the vertical arm 25. The welding gun 28 is set toward the connecting plate 6, and the welding gun 28 is located below the sensing wheel 27 and is distributed at a certain distance from the connecting plate 6 to avoid collision between the welding gun 28 and the connecting plate 6. A plurality of balls 29 are hidden and rotatably installed on both sides of the moving block 22, and sliding areas 30 that cooperate with the balls 29 are provided on both sides of the sliding frame 21. The moving block 22 is actively guided by the balls 29 and the sliding areas 30. When the welding gun 28 follows the moving block 22 for active avoidance, the moving block 22 follows and slides in the sliding frame 21, and the balls 29 are in corresponding rotational contact with the sliding areas 30, so that the movement of the moving block 22 is smoother, the resistance is reduced, and the flexible adjustment of the welding gun 28 is smoother.

[0046] Embodiment 3: Based on the positioning mechanism provided in Embodiment 1, this embodiment provides a further technical solution for the positioning mechanism.

[0047] like Figure 6 and Figure 7As shown, each positioning mechanism includes two guide slideways 31 symmetrically installed in the concave frame 12, the guide slideways 31 and the concave frame 12 are spaced apart, and a lifting plate 32 is slidably engaged with the two guide slideways 31, and friction plates 33 are installed on both sides of the lifting plate 32, and the friction plates 33 are located between the guide slideways 31 and the concave frame 12, and two concave seats 34 are symmetrically installed on the lower surface of the lifting plate 32, and a fixed clamping block 35 is installed on one side of each concave seat 34, and a movable clamping block 36 is slidably engaged with the other side of the concave seat 34, and a No. 3 electric push rod 37 is installed on one side of the concave seat 34, and the output end of the No. 3 electric push rod 37 is transmission-connected with one side of the movable clamping block 36, and the connecting plate 6 is clamped and fixed by the fixed clamping block 35 and the movable clamping block 36, and the two guide slides are fixed. The bottom of the guide rail 31 is rotatably installed with a guide wheel 38 through a bracket. The guide wheel 38 is detachably fixedly connected to the guide slideway 31, and the position of the guide wheel 38 can be freely disassembled and adjusted according to needs. The two guide wheels 38 are used to complete the rotational guidance of the two sides of the connecting plate 6, which is convenient for installation. Two lifting rods 39 are symmetrically installed on the upper surface of the lifting plate 32. The tops of the two lifting rods 39 slide through the concave frame 12 correspondingly, and a second limit head for restriction is installed on the tops of the two lifting rods 39. The outside of the two lifting rods 39 is sleeved with a propulsion spring 40. The two propulsion springs 40 are located between the lifting plate 32 and the concave frame 12. The connecting plate 6 is pushed downward by the two propulsion springs 40 to complete the positioning action. The elastic coefficient of the propulsion spring 40 can be freely selected and used according to processing requirements;

[0048] It is worth noting that when positioning the connecting plate 6: by providing a positioning mechanism, first start the No. 1 electric push rod 9 to push the slide seat 8 to move in the slideway 7 to complete fine-tuning, which is convenient for completing fine-tuning according to different processing environments and is conducive to adjusting the welding position of the connecting plate 6. Then push the connecting plate 6 onto the two concave seats 34, and the guide wheels 38 can guide the connecting plate 6 on both sides, so that the pushing of the connecting plate 6 is smoother and more accurate. Then start the No. 3 electric push rod 37 to push the movable clamping block 36 to move, and complete the rapid clamping and fixing of the connecting plate 6 in cooperation with the fixed clamping block 35. At this time, under the action of the propulsion spring 40, the lifting plate 32 is pushed , the connecting plate 6 elastically moves downward, and then the No. 2 electric push rod 11 is started, pushing the concave frame 12 and the welding unit thereon synchronously toward the column member 2 until they reach the predetermined welding position. In the path where the welding unit reaches the predetermined position, the connecting plate 6 first contacts the column member 2, and under the continuous advancement of the No. 2 electric push rod 11, the advancement spring 40 is compressed, so that the lifting plate 32 provides pressure on the connecting plate 6, so that the connecting plate 6 is stably in contact with the column member 2, ensuring the stability of subsequent welding, making the positioning of the connecting plate 6 time-saving and labor-saving, and reducing the difficulty of debugging. After the subsequent welding is completed, the No. 2 electric push rod 11 and the No. 3 electric push rod 37 can be reset;

[0049] In the embodiment of the present invention, two reinforcing members 41 are symmetrically installed on both sides of the concave frame 12, and the two reinforcing members 41 are arranged in cooperation with the cross beam 10. The two reinforcing members 41 are used to complete the reinforcing and fixing of the connecting plate 6. Each reinforcing member 41 includes a friction block 411 that is slidably engaged at the bottom of the open area 13. The friction block 411 is arranged in cooperation with the friction plate 33, and two return springs 412 are symmetrically installed in the open area 13. The two return springs 412 are connected to the friction block 411, and the friction block 411 is pushed to return to the side away from the friction plate 33 by the two return springs 412. A wedge block 413 is installed on the back of the friction block 411. At the same time, a telescopic arm 414 is detachably installed on one side of the cross beam 10. The telescopic arm 414 specifically adopts one of an electric telescopic arm 414 and a manual telescopic arm 414 to complete the telescopic adjustment work. A trigger wheel 415 is installed at the bottom of the telescopic arm 414 through the bracket rotation, and the trigger wheel 415 contacts the wedge block 413.

[0050] It is worth noting that when the connecting plate 6 is reinforced and positioned: by providing a reinforcement member 41, when the rectangular member 14 and the welding unit move down to a predetermined welding height path, the friction block 411 moves down with the concave frame 12, but the trigger wheel 415 on the telescopic arm 414 gradually approaches and contacts the wedge block 413. After the trigger wheel 415 contacts the wedge block 413, the extrusion action is completed under the guidance of the inclined surface of the wedge block 413. At this time, the friction block 411 approaches the friction plate 33, so that the friction block 411 moves and contacts with the friction plate 33 by friction, thereby completing the secondary fixation of the connecting plate 6, avoiding the displacement of the connecting plate 6, and improving the welding quality. After the subsequent welding is completed, the welding mechanism moves up and resets, so that the trigger wheel 415 is separated from the wedge block 413, and under the push of the reset spring 412, the friction block 411 is reset and moves away from the friction plate 33, thereby completing the unlocking action, and the subsequent installation of the connecting plate 6 can complete the integrated welding work.

[0051] The present invention provides a chimney tower prefabrication processing welding equipment, and the specific working principle is as follows: first, two connecting plates 6 are correspondingly inserted into two positioning mechanisms, so as to complete the rapid positioning of the two connecting plates 6, and then the two welding mechanisms are driven to move toward the column member 2. Under this action, the positioning mechanism completes the follow-up movement, so that the connecting plate 6 restricted thereon moves toward the column member 2, and under the action of the positioning mechanism, the connecting plate 6 is pushed to contact the column member 2 first to complete the positioning. With the joint assistance of the welding mechanism and the positioning mechanism, the welding and positioning work of the connecting plate 6 can be completed synchronously without repeated debugging. After the welding mechanism moves to the predetermined welding position, the connecting plate 6 on the positioning mechanism is synchronously driven to move to the predetermined welding position, which reduces the debugging difficulty and improves the positioning efficiency.

[0052] And through the design of two welding mechanisms and two positioning mechanisms, the welding positioning of the two connecting plates 6 can be completed synchronously, without repeatedly adjusting the position of the connecting plate 6, thereby improving the welding efficiency. Subsequently, the welding mechanism is started to complete the welding process of the contact position of the connecting plate 6 and the column member 2. At the same time, the welding mechanism and the connecting plate 6 are designed with flexible spacing, so that the welding mechanism can ensure a stable spacing and contact welding with the connecting plate 6, ensuring the uniformity of the weld and improving the welding quality. After the welding is completed, the welding mechanism and the positioning mechanism are reset, and then the welding mechanism and the positioning mechanism are driven by the electric slide 3 to move to complete the welding station conversion, which can quickly complete the rapid welding processing of multiple welding points on the column member 2, thereby improving the prefabrication efficiency of the tower and ensuring the accuracy of the tower prefabrication welding, without repeatedly adjusting the position of the connecting plate 6.
