Description

Technical Field

[0001] The utility model relates to the technical field of steel welding, in particular to a cleaning component and a submerged arc welding machine. Background Art

[0002] After welding, there are usually a lot of welding flux residues attached to the welds of the steel sections. Subsequently, workers need to manually clean the residues from the surface of the welds. Although the adhesion strength between the residues and the steel sections is not high, due to the long length of the steel sections, manual cleaning is rather laborious and time-consuming. Therefore, the cleaning component is installed on the gantry, and the gantry is used to drive the cleaning component to move along the welds of the steel sections, so as to take out the residues at the welds together. However, the existing cleaning components are usually fixed to the gantry, resulting in an unadjustable distance between the cleaning component and the steel section, and there is a situation where the cleaning component is in poor contact with the weld, and then there is a situation where residues still remain on the weld after cleaning. Summary of the Utility Model

[0003] Aiming at the deficiencies in the prior art, the utility model provides a cleaning component and a submerged arc welding machine to solve the technical problem of incomplete slag removal in traditional submerged arc welding machines in related technologies.

[0009] Wherein, a clamping claw is arranged on the second connecting rod for detachably clamping at least one of a scraping head or a cleaning head.

[0010] Furthermore, first lifting lugs are formed on both the sliding seat and the second connecting rod, and two ends of the first connecting rod are respectively hinged to the corresponding first lifting lugs.

[0011] Furthermore, a second lifting lug protrudes outwards from the fixed seat, and the end of the second connecting rod is hinged to the second lifting lug.

[0012] Furthermore, the first connecting rod is provided with a bent section for avoiding the second lifting lug.

[0013] Further, a stop block is sleeved on the mounting rod. The stop block is arranged at an interval from the fixed seat, and the sliding seat slides back and forth between the two.

[0027] The realization of the purpose, functional features and advantages of the present utility model will be further described in conjunction with the embodiments with reference to the drawings. Specific embodiments

[0028] In order to make the purpose, technical solutions and beneficial effects of the present utility model more clear and understandable, the technical solutions in the present utility model will be further described below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0029] In the embodiment of the present utility model, as Figure 1 shown, the cleaning assembly includes: an installation rod 1, a slide seat 2, a fixed seat 3 and a connecting rod structure; the slide seat 2 is slidably sleeved on the installation rod 1 in the up and down direction; the fixed seat 3 is arranged at the bottom of the installation rod 1 and is used to abut against or separate from the slide seat 2; at least one connecting rod structure includes a first connecting rod 4 and a second connecting rod 5 which are rotatably connected, and the first connecting rod 4 and the second connecting rod 5 are respectively hinged to the slide seat 2 and the fixed seat 3, so that when the slide seat 2 moves up and down relative to the fixed seat 3, the first connecting rod 4 drives the second connecting rod 5 to extend outwards or contract inwards; wherein, the second connecting rod 5 is provided with a clamping device 6 for detachably clamping at least one of the scraper head 10 and the cleaning head 11.

[0030] Specifically, in the embodiment of the present utility model, the mounting rod 1 serves as a mounting base and is arranged vertically; a sliding seat 2 and a fixed seat 3 are sleeved on its outer surface at intervals in the vertical direction, and the sliding seat 2 can move relative to the fixed seat 3. Specifically, a threaded structure is formed on the outer surface of the mounting rod 1, and the sliding seat 2 is sleeved at the threaded structure, and the sliding seat 2 can be driven to move by rotating the mounting rod 1; of course, in order to prevent the fixed seat 3 from rotating together with the mounting rod 1, a cavity is formed in the fixed seat 3, and the bottom of the mounting rod 1 can rotate freely in the cavity, and at the same time, the cavity can also play a role in restricting the rotation path of the mounting rod 1 to prevent the mounting rod 1 from tilting. Or, the sliding seat 2 is driven by a cylinder, and the linear motion of the cylinder can make the sliding seat 2 slide back and forth on the mounting rod 1. At this time, the fixed seat 3 is arranged at the end of the sliding path of the sliding seat 2 to block the movement of the sliding seat 2.

[0031] In the embodiment of the present utility model, a first connecting rod 4 and a second connecting rod 5 are respectively hinged on the sliding seat 2 and the fixed seat 3. The length of the first connecting rod 4 is less than that of the second connecting rod 5, so that the other end of the first connecting rod 4 is hinged between the two ends of the second connecting rod 5. After the gripper 6 is installed on the second connecting rod 5; during the movement of the sliding seat 2, the first connecting rod 4 and the second connecting rod 5 can respectively rotate around their hinge points with the sliding seat 2 and the fixed seat 3. At the same time, under the action of the connecting hinge point of the two connecting rods, the first connecting rod 4 can drive the second connecting rod 5 to extend outwards or contract inwards, so as to change the distance between the gripper 6 and the steel section weld.

[0032] It can be understood that the outward extension or inward contraction of the second connecting rod 5 is relative to the weld, that is: its rotation path is tangent to the weld; thus, the gripper 6 can move gradually away from or gradually closer to the current weld, and changing the position of the gripper 6 not only facilitates the picking and placing of the steel section, preventing the gripper 6 from forming a dead angle for picking and placing and hindering the picking and placing of the steel section; but also enables the gripper 6 to drive the scraping head 10 or the cleaning head 11 to contact the residue at the weld, and scrape or clean the residue thereon during the movement, avoiding the need for manual secondary cleaning due to insufficient contact distance. Of course, as Figure 1As shown in the figure, the connecting rod structures in this embodiment are provided in two, and are arranged in a circular array with the mounting rod 1 as the center. During installation, the two grippers 6 are suspended one in front of the other above the weld. The gripper 6 located in the front is used to clamp the scraping head 10, and the gripper 6 located in the rear is used to clamp the cleaning head 11. During the overall movement of this cleaning assembly, the scraping head 10 and the cleaning head 11 operate synchronously, and can clean the residue at the weld twice, one in front and the other behind. Of course, in other embodiments, a scraping head 10 or a cleaning head 11 can be provided at one of the grippers 6, and a dust suction box is provided at the other gripper 6. A dust suction fan is provided in the dust suction box, and under the action of the dust suction fan, the residue can be adsorbed into the dust suction box for centralized treatment. Since the gripper 6 adopts a separable clamping method, it is convenient to realize the detachable connection between the gripper 6 and each head, and the corresponding cleaning head (the cleaning head refers to at least one of the scraping head 10, the cleaning head 11 or the dust suction box) can be replaced according to different usage scenarios.

[0033] In this embodiment, the movement of the sliding seat 2 is used to change the rotation angles of the first connecting rod 4 and the second connecting rod 5, so as to adjust the distance between the corresponding cleaning head and the weld. This not only facilitates the picking and placing of the section steel, but also enables the cleaning head to better contact the residue at the weld. Under the movement of the gantry, the whole cleaning assembly is driven to move, so as to achieve the purpose of automatic slag removal.

[0034] As Figure 1 shown, in one embodiment, the sliding seat 2 and the second connecting rod 5 are both formed with first lifting lugs 7, and both ends of the first connecting rod 4 are respectively hinged to the corresponding first lifting lugs 7. Specifically, in order to respectively hinge both ends of the first connecting rod 4 to the sliding seat 2 and the second connecting rod 5, the first lifting lugs 7 are provided on the surface of the sliding seat 2 (if there are two first connecting rods 4, two corresponding first lifting lugs 7 are provided on the surface of the sliding seat 2), and the first lifting lugs 7 are also provided between both ends of the second connecting rod 5. The two lifting lugs are hinged by the first connecting rod 4.

[0035] As Figure 1 shown, in one embodiment, the fixed seat 3 protrudes outwards to form a second lifting lug 8, and the end of the second connecting rod 5 is hinged to the second lifting lug 8. Similarly, in order to enable the second connecting rod 5 to rotate relative to the fixed seat 3, in this embodiment, the second lifting lug 8 is integrally formed on the surface of the fixed seat 3 (similarly, the number of the second lifting lugs 8 increases or decreases according to the number of the second connecting rods 5), so that the upper end of the second connecting rod 5 is hinged to the second lifting lug 8, and its lower end is connected to the gripper 6.

[0036] Preferably, the first connecting rod 4 is provided with a bent section for avoiding the second lifting lug 8. Since the second lifting lug 8 protrudes outwards, in order to enable the first connecting rod 4 and the second connecting rod 5 to be rotatably connected, a bent section is provided in the middle of the first connecting rod 4. A notch is formed between the bent section and the two ends of the first connecting rod 4, and the second lifting lug 8 can be located at the notch so that the two connecting rods can rotate without interfering with each other.

[0037] As Figure 1 shown, in an embodiment, a stopper 9 is sleeved on the mounting rod 1. The stopper 9 is spaced from the fixed seat 3, and the sliding seat 2 slides back and forth between the two. Specifically, in order to define the moving distance of the sliding seat 2, in this embodiment, a stopper 9 is fixedly sleeved outside the mounting rod 1. The stopper 9 and the fixed seat 3 are spaced along the up and down direction. In this way, the sliding seat 2 can slide back and forth between the stopper 9 and the fixed seat 3, and can abut against the stopper 9 and the fixed seat 3 respectively at the head and tail ends to forcibly limit the sliding seat 2 from continuing to move, so as to ensure the rotation angle of the two connecting rods. Of course, in actual operation, the distance between the stopper 9 and the fixed seat 3 can be increased or decreased according to actual installation requirements, and the ultimate goal is to change the distance from each cleaning head to the weld.

[0038] As Figure 2 shown, in an embodiment, the gripper 6 includes a first clamping block 601 fixed to the second connecting rod 5 and a second clamping block 602 rotatable relative to the first clamping block 601. The first clamping block 601 is provided with a locking screw 603 for passing through the second clamping block 602. A wing nut 606 is sleeved on the locking screw 603 for abutting against the second clamping block 602. Specifically, in order to detachably fix each cleaning head to the gripper 6, in this embodiment, the gripper 6 is defined as a first clamping block 601 and a second clamping block 602 that are rotatably connected. The first clamping block 601 can be directly fixed to the second connecting rod 5, or as Figure 1 shown, it can be fixed to the second connecting rod 5 by using a support rod after extending through the support rod. The second clamping block 602 can rotate relative to the first clamping block 601, so as to change the distance between the two clamping blocks, so as to facilitate clamping or releasing the cleaning head therebetween.

[0039] On the other hand, in order to lock the cleaning head between the two clamping blocks, a locking screw 603 is provided on the first clamping block 601. One end of the locking screw 603 passes through the second clamping block 602 and is threadedly provided with a wing nut 606. Rotating the wing nut 606 can push the second clamping block 602 to gradually approach the first clamping block 601, so as to facilitate reducing the distance between the two, thereby clamping the cleaning head therebetween. Of course, a gasket can be provided between the wing nut 606 and the second clamping block 602 for protection.

[0040] Further, asFigure 2 As described above, in one embodiment, a spring 604 is sleeved on the locking screw 603 located between the first clamping block 601 and the second clamping block 602, and two ends of the spring 604 respectively abut against opposite end faces of the first clamping block 601 and the second clamping block 602. Specifically, on the one hand, it can play a buffering role, and on the other hand, it can make the second clamping block 602 automatically reset during the process of loosening the wing nut 606. In this embodiment, a spring 604 is arranged between the first clamping block 601 and the second clamping block 602, and the spring 604 is sleeved outside the locking screw 603. When the distance between the two clamping blocks decreases, the spring 604 is compressed; on the contrary, the spring 604 restores its deformation.

[0041] As Figure 2 shown, in one embodiment, opposite end faces of the first clamping block 601 and the second clamping block 602 are bent outward to form a clamping cavity 605 therebetween, and a support column 12 adapted to the clamping cavity 605 is provided on the scraping head 10 and / or the cleaning head 11. Specifically, in order to firmly fix the cleaning head between the two clamping blocks, lower portions of the two clamping blocks are bent outward to form a clamping cavity 605 in a shape similar to a circular structure, so as to cooperate with the support column 12 on the upper portion of the cleaning head. The support column 12 is also arranged in a cylindrical structure, so that the contact area with the clamping cavity 605 can be increased, so as to clamp and fix the cleaning head in the clamping cavity 605.

[0042] As Figure 3 shown, the bottom of the scraping head 10 is configured as an arc-shaped scraping portion for scraping off residues at the weld. In other embodiments, when the section steel is H-shaped steel and it is welded in an inclined placement manner, the weld is formed at a 90° angle. Therefore, the scraping portion of the scraping head 10 is arranged in a strip shape and is used to extend into the above-mentioned angle; it can be understood that the above-mentioned scraping portion can be adaptively changed according to the structure of the corresponding section steel; of course, the arc-shaped scraping portion can collect residues. In addition, as Figure 4 shown, a plurality of bristles are provided at the bottom of the cleaning head 11 for cleaning residues at the weld.

[0043] This embodiment also provides a submerged arc welding machine, which includes a gantry and the cleaning assembly described above. The mounting rod 1 of the cleaning assembly is telescopically mounted at the gantry to indirectly change the distance between the cleaning head and the weld seam, which can further improve the cleaning intensity of this equipment and facilitate the placement and removal of the profiled steel at the welding rack, enabling it to be placed obliquely or horizontally. Of course, in order to improve the adaptability and coordination of this device, the mounting rod 1 can be connected to the gantry by means of external structures such as a mounting base (not shown). The specific structure of this cleaning assembly refers to the above embodiment. Since this submerged arc welding machine adopts all the technical solutions of the above embodiment, it at least has all the beneficial effects brought by the technical solutions of the above embodiment, and will not be elaborated here one by one.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
