Description

Technical Field

[0001] The invention relates to the field of welding auxiliary technology, and in particular to an automatic conveying device and a surfacing welding system for strip-electrode submerged arc surfacing slag shell. Background Art

[0002] Submerged arc welding with a polar electrode is a special welding process, which is mainly used to weld a corrosion-resistant, wear-resistant or other special alloy layer on the metal surface. This process is particularly suitable for the manufacture of hydrogenation reactor cylinders, because the working environment of hydrogenation reactors is usually very harsh and requires resistance to high temperature, high pressure, corrosion and wear. During the submerged arc welding process of hydrogenation reactor cylinders, a large amount of slag shells will be generated, and the slag shells will have a certain impact on the welding process, so the welding slag needs to be recycled.

[0003] In the prior art, each cladding welding station is equipped with a slag shell collection box. During welding, the slag shell is mainly collected manually into the slag shell collection box. When the slag shell collection box is full, it needs to be hoisted to a designated location by a crane. Although the slag shell can be recycled in this way, manual collection of slag shell is too time-consuming and labor-intensive. Not only is the efficiency of recycling slag shell low, but it also affects the efficiency of welding. In addition, the slag shell collection box occupies a large space, affecting the passage of personnel and materials. The crane needs to be frequently called, which seriously wastes crane resources.

[0007] Optionally, the middle section conveyor includes a conveyor frame, a conveyor belt, a conveyor belt shaft, a conveying motor and casters. The conveyor belt shaft is arranged inside the conveyor frame and extends along a first direction. The conveyor belt is sleeved on the conveyor belt shaft. The conveying motor is installed on the conveyor frame and connected to the conveyor belt shaft for driving the conveyor belt to move in a second direction, which is perpendicular to the first direction. The casters are installed at the bottom end of the conveyor frame for moving the middle section conveyor.

[0012] Optionally, an aluminum alloy profile plate is provided on the side of the middle section conveyor, and the aluminum alloy profile plate is connected to the connecting end of the upper slag guide groove through a hinge.

[0013] Optionally, the automatic conveying device further includes an electrical control cabinet, which is electrically connected to the middle-section conveyor and the last-section conveyor, respectively, and is used to control the opening and closing of the middle-section conveyor and the last-section conveyor.

[0014] In a second aspect, the present invention provides a surfacing welding system, comprising the automatic conveying device for strip-electrode submerged arc surfacing slag shell as described in the first aspect.

[0015] The beneficial effects of the automatic conveying device and surfacing system for strip-electrode submerged arc surfacing slag shell of the present invention are:

Since the middle section conveyor and the end section conveyor are both arranged between the surfacing station and the safety passage, and are parallel to the surfacing station, not only can the effective transportation of the slag shell be guaranteed, but also a safe passage path is provided, the probability of safety accidents is reduced, and the problem that the slag shell collection box occupies a large space and affects the passage of personnel and materials is solved. Moreover, by only setting the slag shell collection box at the end of the end section conveyor, the unified collection of the slag shells of all welding stations and the unified call of the overhead crane can be realized, which not only greatly reduces the number of slag shell collection boxes and saves costs, but also reduces the frequency of calling the overhead crane and saves overhead crane resources. In addition, by the slag blocking surface of the slag blocking plate facing the upper slag guide groove, and the width of the slag blocking surface is greater than the width of the upper slag guide groove, the elastic collision phenomenon caused by the excessive gravitational potential energy of the slag shell in the process of sliding to the middle section conveyor can be effectively prevented, and the slag shell is prevented from falling when it contacts the middle section conveyor, thereby improving the effect of slag shell collection.

[0028] It should be noted that the modifications of "one" and "plurality" mentioned in the present invention are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0029] In view of the problems existing in the above-mentioned related technologies, such as Figure 1 , Figure 2 as well as Figure 5As shown, an automatic conveying device and a surfacing system for strip-electrode submerged arc surfacing slag shell provided by an embodiment of the present invention include at least one upper slag guide trough 1, at least one intermediate section conveyor 2, a final section conveyor 3 and a slag shell collecting box 4, wherein the upper slag guide trough 1 corresponds to the surfacing welding station 5 one by one, and the slag receiving end of the upper slag guide trough 1 faces the surfacing welding station 5, and is used to receive the slag shell generated by the surfacing welding station 5, the connecting end of the upper slag guide trough 1 is connected to the side of the intermediate section conveyor 2, the slag receiving end is higher than the connecting end, the intermediate section conveyor 2 and the final section conveyor 3 are both arranged between the surfacing welding station 5 and Between the safety passage 6 and in parallel with the safety passage 6, all the middle section conveyors 2 are connected head to tail in sequence, and the tail end of the last middle section conveyor 2 is connected to the head end of the last section conveyor 3 to convey the slag shell to the last section conveyor 3, and the slag shell collecting box 4 is provided below the tail end of the last section conveyor 3 to convey the slag shell to the slag shell collecting box 4, and a slag blocking plate 201 is provided on the side of the middle section conveyor 2 away from the upper slag guide groove 1, and the slag blocking surface of the slag blocking plate 201 faces the upper slag guide groove 1, and the width of the slag blocking surface is greater than the width of the upper slag guide groove 1.

[0030] Specifically, the upper slag guide trough 1 corresponds to the surfacing station 5 one by one, that is, each surfacing station 5 is provided with an upper slag guide trough 1 to collect the slag shell generated by each surfacing station 5. The slag receiving end of the upper slag guide trough 1 faces the surfacing station 5, and the connecting end of the upper slag guide trough 1 is connected to the side of the middle section conveyor 2, and the slag receiving end is higher than the connecting end, so that after the upper slag guide trough 1 receives the slag shell, the slag shell can slide from the slag receiving end to the connecting end under the action of gravity and enter the middle section conveyor 2. The middle section conveyor 2 and the last section conveyor 3 are both arranged between the surfacing station 5 and the safety passage 6, and are parallel to the safety passage 6, and all the middle section conveyors 2 are connected head to tail in sequence, and the tail end of the last middle section conveyor 2 is connected to the head end of the last section conveyor 3, so that at least one middle section conveyor 2 and the last section conveyor 3 can form an automatic transportation assembly line, such as Figure 1As shown, 7 middle section conveyors 2 and 1 end section conveyor 3 can be arranged to form an automatic transport assembly line. Thus, the slag shells produced by each surfacing station 5 are automatically transported to the slag shell collection box 4 at the end of the assembly line. Among them, the tail end of the middle section conveyor 2 is higher than the head end of the next middle section conveyor 2, and the tail end of the last middle section conveyor 2 is higher than the head end of the end section conveyor 3. The middle section conveyors 2 and the middle section conveyors 2, as well as the middle section conveyors 2 and the end section conveyor 3 are connected by mechanical connecting pins, which facilitates the effective connection of the slag shells transported between different conveyors, so that the slag shells are transported to the slag shell collection box 4 below the tail end of the end section conveyor 3. A slag blocking plate 201 is provided on the other side of the middle section conveyor 2, i.e., the side away from the upper slag guide groove 1. A slide groove is provided at the bottom of the slag blocking plate 201, and the slide groove opening faces the other side of the middle section conveyor 2, and the slide groove is buckled on the other side of the middle section conveyor 2, so that the slag blocking plate 201 can slide along the conveying direction on the other side of the middle section conveyor 2 and is detachable. The slag blocking surface of the slag blocking plate 201 faces the upper slag guide groove 1 and is at a certain angle to reduce the elastic potential energy converted from the gravitational potential energy of the slag shell when it contacts the middle section conveyor 2, thereby avoiding the secondary bounce caused by excessive elastic potential energy causing the slag shell to bounce off, and the width of the slag blocking surface is greater than the cross-sectional width of the upper slag guide groove 1, so that the slag blocking area is greater than the active area of ​​the slag shell in the upper slag guide groove 1, so as to maximize the blocking of the slag shell from bouncing off the middle section conveyor 2.

[0031] It should be understood that the structure of the final conveyor 3 may be the same as that of the middle conveyor 2, that is, the side of the final conveyor 3 may also be connected to the upper slag guide groove 1, and the other side of the final conveyor 3 may also be provided with a slag retaining plate, the slag retaining surface of the slag retaining plate faces the upper slag guide groove 1, and the width of the slag retaining surface is greater than the width of the upper slag guide groove 1. However, the height difference between the head end and the tail end of the final conveyor 3 is different from the height difference between the head end and the tail end of the middle conveyor 2, and the height difference between the head end and the tail end of each middle conveyor 2 may also be different.

[0032] For example, the lengths of the middle section conveyor 2 and the last section conveyor 3 can be set according to actual conditions. For example, the length of the middle section conveyor 2 is set to 8000 mm, and the length of the last section conveyor 3 is set to 7000 mm. Thus, at least one upper slag guide trough 1 can be installed on the sides of the middle section conveyor 2 and the last section conveyor 3, and the middle section conveyor 2 and the last section conveyor 3 are provided with slag retaining plates corresponding to the number of upper slag guide troughs 1 to ensure that the slag shells in all upper slag guide troughs 1 will not fall off. Alternatively, the upper slag guide trough 1 may not be installed according to actual conditions, such as Figure 6As shown, based on the actual situation, there is no surfacing station 5 at the location of the middle section conveyor 2, and the upper slag guide groove 1 and the corresponding slag blocking plate 201 do not need to be set, and only the slag shells transmitted by other middle section conveyors 2 are transported, and the slag shells are transported to the next middle section conveyor 2. The last section conveyor 3 is similar to the middle section conveyor 2, and will not be repeated here.

[0033] The slag shells are collected by the conveyor belt 1 and the conveyor belt 2 is connected to the conveyor belt 2 by the conveyor belt 2. Since the middle section conveyor 2 and the end section conveyor 3 are both arranged between the surfacing station 5 and the safety passage 6, and are parallel to the safety passage 6, not only can the effective transportation of the slag shell be guaranteed, but also a safe passage path is provided, the probability of safety accidents is reduced, and the problem that the slag shell collection box occupies a large space and affects the passage of personnel and materials is solved. Moreover, by only setting the slag shell collection box 4 at the end of the end section conveyor 3, the unified collection of slag shells of all welding stations and the unified call of the overhead crane can be realized, which not only greatly reduces the number of slag shell collection boxes 4 and saves costs, but also reduces the frequency of calling the overhead crane and saves overhead crane resources. In addition, by the slag blocking surface of the slag blocking plate 201 facing the upper slag guide groove 1, and the width of the slag blocking surface is greater than the width of the upper slag guide groove 1, the elastic collision phenomenon caused by the excessive gravitational potential energy of the slag shell in the process of sliding to the middle section conveyor 2 can be effectively prevented, and the slag shell is prevented from falling when it contacts the middle section conveyor 2, thereby improving the effect of slag shell collection.

The second support rod is perpendicular to the middle part of the first support rod, that is, the first support rod and the second support rod are in a "T" shape, and the ... 1 is provided with through holes matching the shapes of the two ends of the first support rod, so that the first support rod passes through the through holes and rotates in the through holes, so as to realize the rotation connection between the bracket 102 and the support seat 101, and then the second support rod as the connection end is connected with one end of the telescopic support rod 103, so that the telescopic support rod 103 can rotate with the support seat 101 as the fulcrum, thereby adjusting the support angle of the telescopic support rod 103, and then through the telescopicity of the telescopic support rod 103, the support height of the telescopic support rod 103 can be adjusted, and then the height of the slag receiving end of the upper slag guide groove 1 can be adjusted. The surfacing welding station 5 includes a petrochemical product barrel section, a barrel section roller and a strip-electrode submerged arc welding heavy-duty manipulator. By adjusting the slag receiving end of the upper slag guide groove 1 to a suitable height, it not only does not affect the strip-electrode submerged arc welding heavy-duty manipulator to weld the petrochemical product barrel section, but also facilitates the introduction of the slag shell into the upper slag guide groove 1.

[0036] For example, the bracket 102 can be fixed on the lower surface of the upper slag guide groove 1 near the slag connection end, for example, 500mm away from the slag connection end port, to increase the supporting moment, improve the supporting effect, and facilitate changing the height of the slag connection end.
