Description

Technical Field

[0001] This application relates to the field of water truck tank welding technology, and in particular to a wave deflector welding device for a mining water truck. Background Technology

[0002] Mining sprinkler trucks are important dust suppression and cooling equipment in mining operations. Their tanks typically require the installation of baffles to reduce liquid sloshing during transport, thereby improving vehicle stability. These baffles are usually curved or irregularly shaped and need to be welded and fixed to specific locations inside the tank with high precision to ensure a good fit and strong connection between the baffle and the tank wall.

[0003] Currently, the traditional welding process for baffles on mining sprinkler trucks mostly involves manual welding: operators must enter the tank and use a handheld welding torch to weld the baffle to the tank. However, this method is not only dangerous but also inefficient and needs improvement. Summary of the Invention

[0004] In order to reduce the welding risks of wave deflectors and improve welding efficiency, this application provides a welding device for wave deflectors of mining sprinkler trucks.

[0005] This application provides a welding device for baffle plates of a mining sprinkler truck, including a support platform for supporting the sprinkler truck tank. Multiple baffle plates are installed inside the tank, each baffle plate including a central through hole and edge holes. The device further includes: a column with a lifting mechanism and a lateral movement mechanism; a horizontal column slidably mounted on the column, with one end of the horizontal column away from the column extending into the through hole of the baffle plate; the lifting mechanism driving the horizontal column to slide vertically on the column, and the lateral movement mechanism driving the horizontal column to slide horizontally on the column; a welding mechanism rotatably mounted on the end of the horizontal column away from the column, with its rotation axis extending along the axis of the through hole of the baffle plate; and a positioning mechanism mounted on the column near the welding mechanism and located within the through hole, for positioning and fixing the baffle plates inside the tank.

[0006] By adopting the above technical solution, when welding the baffle plate to the tank body, the baffle plate is first electric welded into the tank body, so that the tank body and the baffle plate can be placed together on the support platform. Then, the lifting mechanism on the column drives the horizontal column to move vertically to the center of the tank opening. Then, the lateral movement mechanism drives the horizontal column to move into the tank body until the positioning mechanism on the horizontal column is located in the through hole of the baffle plate to position the baffle plate, thereby fixing the baffle plate in the tank body. This allows the welding mechanism to weld the connection between the baffle plate and the tank body around the baffle plate. This arrangement, through the cooperation of the lifting mechanism and the lateral movement mechanism, allows the welding mechanism to perform welding while the positioning mechanism positions and fixes the baffle plate in the tank body, replacing the manual positioning and fixing of the baffle plate, thereby reducing the welding risks of the baffle plate and improving welding efficiency.

[0007] Optionally, the welding mechanism includes a first robotic arm and a second robotic arm rotatably mounted on the crossbar. The first robotic arm and the second robotic arm are symmetrically arranged on both sides of the baffle plate. The ends of the first robotic arm and the second robotic arm are equipped with welding guns, which are used to weld the two sides of the connection between the baffle plate and the tank body.

[0008] By adopting the above technical solution, when welding the connection between the baffle plate and the tank body, the horizontal column moves into the through hole of the baffle plate inside the tank body, so that the first robot arm and the second robot arm are located on both sides of the baffle plate respectively, and the welding gun on the first robot arm faces one side of the baffle plate, and the welding gun on the second robot arm faces the other side of the baffle plate, so as to realize the simultaneous welding of the connection between the two sides of the baffle plate and improve the welding efficiency.

[0009] Optionally, the horizontal column is respectively equipped with a first rotating column connected to the first robotic arm and a second rotating column connected to the second robotic arm. The rotation axes of the first rotating column and the second rotating column are parallel to the axis of the through hole of the wave deflector. The first rotating column and the second rotating column rotate on the upper side of the horizontal column, and the horizontal column is located on the lower side of the first rotating column and the second rotating column, corresponding to the edge hole of the wave deflector.

[0010] By adopting the above technical solution, when welding along the connection of the baffle plate, because the baffle plate has edge holes, the first robot arm and the second robot arm do not need to rotate a full circle to weld the connection between the baffle plate and the tank body, thus facilitating the first and second robot arms to weld along the edge of the baffle plate.

[0011] Optionally, the crossbar is provided with a first motor for driving the first rotating column to rotate and a second motor for driving the second rotating column to rotate.

[0012] By adopting the above technical solution, the first motor drives the first rotating column to drive the first robotic arm to weld along the circumference of the wave deflector, and the second motor drives the second rotating column to drive the second robotic arm to weld along the circumference of the wave deflector.

[0013] Optionally, the first rotating column is provided with a first receiving groove for the first robotic arm to fold into a deformable shape, and the second rotating column is provided with a second receiving groove for the second robotic arm to fold into a deformable shape.

[0014] By adopting the above technical solution, when the horizontal column enters the through hole of the tank to the baffle plate, the first robotic arm can deform and fold into the first receiving groove, and the second robotic arm can deform and fold into the second receiving groove. Until the horizontal column enters and the first and second robotic arms are respectively located on both sides of the baffle plate, the first robotic arm deforms and unfolds from the first receiving groove, and the second robotic arm deforms and unfolds from the second receiving groove, thereby facilitating the storage of the first and second robotic arms and reducing the volume of the horizontal column.

[0015] Optionally, the positioning mechanism includes: a first positioning rod, rotatably mounted on the horizontal column and located between the first robotic arm and the second robotic arm; a second positioning rod, rotatably mounted on the horizontal column and located between the first robotic arm and the second robotic arm; and a driving member, disposed within the horizontal column, which drives the first positioning rod to rotate upward and the second positioning rod to rotate downward respectively; wherein the rotation axes of the first positioning rod and the second positioning rod are both perpendicular to the length direction of the column and the horizontal column, the first positioning rod and the second positioning rod are symmetrically arranged along the length direction of the horizontal column, and both the first positioning rod and the second positioning rod are provided with positioning grooves for the through-hole wall of the wave deflector to be engaged.

[0016] By adopting the above technical solution, when the first and second robotic arms are located on both sides of the baffle plate and unfolded, the driving component drives the first positioning rod to rotate upward and the second positioning rod to rotate downward, so that the first and second positioning rods located in the through hole are engaged with the through hole wall of the baffle plate through the positioning groove. This allows the baffle plate to be restricted from shifting or rotating inside the tank by the symmetrical engagement of the first and second positioning rods, thereby ensuring the stability of the baffle plate welding.

[0017] Optionally, the driving component includes a first toothed rod and a second toothed rod that are slidably disposed within the crossbar. The first toothed rod and the second toothed rod slide toward each other along the length direction of the crossbar. The first positioning rod is provided with a first gear that meshes with the first toothed rod, and the second positioning rod is provided with a second gear that meshes with the second toothed rod. After the first toothed rod and the second toothed rod slide and abut against each other, the first positioning rod rotates upward and the second positioning rod rotates downward, so that the wall of the through hole of the wave deflector plate is engaged with the positioning groove.

[0018] By adopting the above technical solution, when the first positioning rod and the second positioning rod are driven to rotate, the first gear and the second gear slide towards each other, causing the first gear to drive the first gear to rotate counterclockwise, which in turn drives the first positioning rod to rotate upward. This causes the second gear to drive the second gear to rotate clockwise, which in turn drives the second positioning rod to rotate downward. This continues until the first positioning rod and the second positioning rod are engaged with the wall of the through hole of the wave deflector through the positioning groove, thereby achieving the positioning and fixing of the wave deflector. This completes the positioning and fixing of the wave deflector by the reverse rotation of the first positioning rod and the second positioning rod.

[0019] Optionally, the first motor has a first lead screw coaxially connected to its output shaft passing through the first rotating column, and the second motor has a second lead screw coaxially connected to its output shaft passing through the second rotating column. The first lead screw is threaded into the interior of the end of the first toothed rod away from the second toothed rod, and the second lead screw is threaded into the interior of the end of the second toothed rod away from the first toothed rod. When the first toothed rod and the second toothed rod abut against each other, the first lead screw disengages from the threaded connection of the first toothed rod, and the second lead screw disengages from the threaded connection of the second toothed rod.

[0020] By adopting the above technical solution, when the first motor drives the first rotating column and the first robotic arm to rotate, and the second motor drives the second rotating column and the second robotic arm to rotate, the first motor drives the first lead screw to rotate, and the first toothed rod slides towards the second toothed rod under the rotation of the first lead screw; the second motor drives the second lead screw to rotate, and the second toothed rod slides towards the first toothed rod under the rotation of the second lead screw, until the first toothed rod and the second toothed rod abut against each other. At this time, the first positioning rod and the second positioning rod are engaged with the wall of the through hole of the baffle plate, completing the positioning and fixing of the baffle plate. However, at this time, the first motor continues to drive the first rotating column, the first lead screw, and the first robotic arm to rotate, and the second motor continues to drive the second rotating column, the second lead screw, and the second robotic arm to rotate, so as to weld the baffle plate to the tank body. After welding is completed, the lifting mechanism moves the horizontal column upward. The reaction force of the wave deflector acts on the first positioning rod, pushing it downward. Simultaneously, the first motor drives the first lead screw to rotate in the opposite direction, reconnecting the lead screw and the first toothed rod with a threaded connection. This allows the first toothed rod and the second toothed rod to separate under the reverse rotation of the lead screw, and the first positioning rod to rotate downward and disengage from the wall of the wave deflector's through-hole. Then, the lifting mechanism moves the horizontal column downward. The reaction force of the wave deflector acts on the second positioning rod, pushing it upward. Simultaneously, the second motor drives the second lead screw to rotate in the opposite direction, reconnecting the lead screw and the second toothed rod with a threaded connection. This allows the second toothed rod to continue moving away from the first toothed rod under the reverse rotation of the lead screw, and the second positioning rod to rotate upward and disengage from the wall of the wave deflector's through-hole. The lifting mechanism drives the horizontal column to move up and down, so that the reaction force of the baffle plate acts on the first positioning rod and the second positioning rod. Under the rotational cooperation of the first lead screw and the second lead screw, they are re-threaded to the first toothed rod and the second toothed rod respectively, realizing the automatic release of the baffle plate's positioning and fixing, thus facilitating the removal of the horizontal column, the first manipulator, and the second manipulator from the tank and the baffle plate.

[0021] Optionally, the lifting mechanism includes: a lifting slider, which is slidably connected to the horizontal column in a horizontal direction; a screw, which passes through and is threadedly connected to the lifting slider in a vertical direction, and the rotation axis of the screw extends in a vertical direction; and a lifting motor, which is disposed at the top of the column and coaxially connected to the screw.

[0022] By adopting the above technical solution, when the horizontal column moves up and down, the lifting motor drives the screw to rotate. After the screw rotates, it drives the lifting slider to move up and down in the vertical direction. At the same time, the lifting slider drives the horizontal column to move up and down in the vertical direction. The lifting slider slides inside the horizontal column so that when the horizontal column moves horizontally, the lifting slider maintains the threaded connection with the screw.

[0023] Optionally, the side wall of the horizontal column is provided with a row of vertical teeth, and the horizontal movement mechanism includes: a drive gear, which rotates inside the column and meshes with the teeth; a drive rod, which is coaxially connected to the drive gear, and the rotation axis of the drive rod extends in the vertical direction; and a horizontal movement motor, which is disposed at the top of the column and coaxially connected to the drive rod.

[0024] By adopting the above technical solution, when the horizontal column slides in and out of the tank, the horizontal movement motor drives the drive rod to rotate, the drive rod drives the drive gear to rotate, and the drive gear drives the horizontal column to slide in the horizontal direction through meshing with the tooth pattern, so as to send the first and second robotic arms into and out of the tank.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] By coordinating the lifting mechanism and the lateral movement mechanism, the welding mechanism can perform welding while the positioning mechanism positions and fixes the baffle plate inside the tank, thus replacing the manual welding process of positioning and fixing the baffle plate, reducing welding risks and improving welding efficiency.

[0027] The first and second positioning rods are engaged with the through hole wall of the baffle plate through the positioning groove, so that the baffle plate can be restricted from shifting or rotating in the tank by the symmetrical engagement of the first and second positioning rods, thereby ensuring the stability of the baffle plate welding.

[0028] The lifting mechanism drives the horizontal column to move up and down, so that the reaction force of the baffle plate acts on the first positioning rod and the second positioning rod. Under the rotational cooperation of the first lead screw and the second lead screw, they are re-threaded to the first toothed rod and the second toothed rod respectively, realizing the automatic release of the baffle plate's positioning and fixing, thus facilitating the removal of the horizontal column, the first manipulator, and the second manipulator from the tank and the baffle plate.

[0035] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0036] Reference Figure 1 and Figure 2 This application discloses a welding device for baffle plates of a mining sprinkler truck, including a support platform 6 for receiving the sprinkler truck tank 1. Multiple baffle plates 11 are provided inside the tank 1. Each baffle plate 11 includes a central through hole 12 and an edge hole 13. The multiple baffle plates 11 are evenly spaced along the length of the tank 1. Before the tank 1 is placed on the support platform 6, the bottom wall of the baffle plate 11 near the edge hole 13 is spot-welded to the inner wall of the tank 1 to form a preliminary positioning, so that the edge hole 13 is placed on the support platform 6 at the lower end of the tank 1 for welding by the welding device.

[0037] The welding device includes a column 2, a horizontal column 3, a welding mechanism 4, and a positioning mechanism 5 (the welding mechanism 4 and the positioning mechanism 5 are in...). Figure 4 The column 2 is equipped with a lifting mechanism 21 and a horizontal movement mechanism 22; the horizontal column 3 is slidably mounted on the column 2, with one end of the horizontal column 3 away from the column 2 extending into the through hole 12 of the baffle plate 11. The lifting mechanism 21 is used to drive the horizontal column 3 to slide vertically on the column 2, and the horizontal movement mechanism 22 is used to drive the horizontal column 3 to slide horizontally on the column 2; the welding mechanism 4 is rotatably mounted on the end of the horizontal column 3 away from the column 2, with the rotation axis extending along the axis of the through hole 12 of the baffle plate 11; the positioning mechanism 5 is mounted on the column 2 near the welding mechanism 4 and located in the through hole 12, and is used to position and fix the baffle plate 11 inside the tank 1.

[0038] In this embodiment, one end of the horizontal column 3 slides horizontally through the column 2, and the other end extends into the tank body 1. As the horizontal column 3 slides horizontally, it causes the welding device and the positioning device to weld multiple anti-surge plates 11 in the tank body 1 in sequence. Specifically, the welding can be performed sequentially through the through holes 12 in the anti-surge plates 11.

[0039] In some embodiments, refer to Figure 2 and Figure 3 The lifting mechanism 21 includes a lifting slider 211, a screw 212, and a lifting motor 213. The lifting slider 211 is slidably connected to the horizontal column 3 in the horizontal direction; the screw 212 passes through and is threadedly connected to the lifting slider 211 in the vertical direction, and the rotation axis of the screw 212 extends in the vertical direction; the lifting motor 213 is located at the top of the column 2 and is coaxially connected to the screw 212.

[0040] In this embodiment, the lifting motor 213 is fixed to the top wall of the column 2, and the screw 212 coaxially connected to the lifting motor 213 vertically downwards through the lifting slider 211 and is threadedly connected. The lifting slider 211 and the horizontal column 3 are slidably connected by a T-shaped sliding connection, so that the horizontal column 3 remains slidably connected to the lifting slider 211 when it slides horizontally, and the lifting slider 211 can still drive the horizontal column 3 to slide up and down under the drive of the lifting motor 213 when the screw 212 rotates.

[0041] In some embodiments, the sidewall of the horizontal column 3 is provided with a row of vertical teeth 31. The lateral movement mechanism 22 includes a drive gear 221, a drive rod 222, and a lateral movement motor 223. The drive gear 221 rotates within the column 2 and meshes with the teeth 31; the drive rod 222 is coaxially connected to the drive gear 221, and the rotation axis of the drive rod 222 extends vertically; the lateral movement motor 223 is disposed at the top of the column 2 and coaxially connected to the drive rod 222.

[0042] In this embodiment, the transverse motor 223 and the lifting motor 213 are fixed side by side to the top wall of the column 2. The drive rod 222 and the screw 212 are arranged in parallel. The toothed groove 31 is arranged back to back with the lifting slider 211. The drive rod 222 rotates inside the column 2, driving the drive gear 221 to rotate, so that the transverse column 3 slides horizontally as the drive gear 221 rotates through the meshing of the toothed groove 31 and the drive gear 221.

[0043] In some embodiments, refer to Figure 4 The welding mechanism 4 includes a first robotic arm 41 and a second robotic arm 42 rotatably mounted on the horizontal column 3. The first robotic arm 41 and the second robotic arm 42 are symmetrically arranged on both sides of the wave deflector 11. The ends of the first robotic arm 41 and the second robotic arm 42 are equipped with welding guns, which are used to weld the two sides of the connection between the wave deflector 11 and the tank body 1.

[0044] In this embodiment, both the first robotic arm 41 and the second robotic arm 42 have joints that allow for free movement, so that after the crossbar 3 slides into the through hole 12 of the wave deflector 11, the first robotic arm 41 and the second robotic arm 42 are positioned on both sides of the wave deflector 11, respectively. The first robotic arm 41 and the second robotic arm 42 can be arranged symmetrically or asymmetrically along the wave deflector 11. The first robotic arm 41 and the second robotic arm 42 can be programmed with parameters to weld the two sides of the wave deflector 11, achieving spot welding in the circumferential direction of the wave deflector 11.

[0045] In some embodiments, a first rotating column 32 connected to a first robotic arm 41 and a second rotating column 33 connected to a second robotic arm 42 are respectively rotatably mounted on the horizontal column 3. The rotation axes of the first rotating column 32 and the second rotating column 33 are parallel to the axis of the through hole 12 of the wave deflector 11. The first rotating column 32 and the second rotating column 33 rotate on the upper side of the horizontal column 3, and the edge hole 13 of the wave deflector 11 is located on the lower side of the first rotating column 32 and the second rotating column 33.

[0046] In this embodiment, the rotation axes of the first rotating column 32 and the second rotating column 33 both extend along the length of the horizontal column 3. The first rotating column 32 and the second rotating column 33 are rotatably connected to the upper part of the horizontal column 3, so that the lower part of the horizontal column 3 can be connected to support the positioning mechanism 5, allowing the first robotic arm 41 and the second robotic arm 42 to be positioned on opposite sides of the wave deflector 11. The blind spots where the first rotating column 32 and the second rotating column 33 drive the first robotic arm 41 and the second robotic arm 42 to rotate are precisely where the lower edge hole 13 of the wave deflector 11 does not require welding.

[0047] In some embodiments, the horizontal column 3 is provided with a first motor 34 for driving the first rotating column 32 to rotate and a second motor 35 for driving the second rotating column 33 to rotate. The first motor 34 is located on the side of the first rotating column 32 away from the wave deflector 11, and the second motor 35 is located on the side of the second rotating column 33 away from the wave deflector 11.

[0048] In some embodiments, the first rotating column 32 is provided with a first receiving groove 321 for the first robotic arm 41 to fold and deform into its shape, and the second rotating column 33 is provided with a second receiving groove 331 for the second robotic arm 42 to fold and deform into its shape.

[0049] In some embodiments, refer to Figure 4 and Figure 5 The positioning mechanism 5 includes a first positioning rod 51, a second positioning rod 52, and a driving member. The first positioning rod 51 rotates on the horizontal column 3 and is located between the first robotic arm 41 and the second robotic arm 42; the second positioning rod 52 rotates on the horizontal column 3 and is located between the first robotic arm 41 and the second robotic arm 42; the driving member is disposed inside the horizontal column 3 and drives the first positioning rod 51 to rotate upward and drives the second positioning rod 52 to rotate downward.

[0050] The rotation axes of the first positioning rod 51 and the second positioning rod 52 are both perpendicular to the length direction of the column 2 and the horizontal column 3. The first positioning rod 51 and the second positioning rod 52 are symmetrically arranged along the length direction of the horizontal column 3. The first positioning rod 51 and the second positioning rod 52 are both provided with positioning grooves 53, which are used to insert the walls of the through holes 12 of the wave deflector 11.

[0051] In this embodiment, the first positioning rod 51 and the second positioning rod 52 are symmetrically arranged along the center of the through hole 12 of the wave deflector 11. The rotation directions of the first positioning rod 51 and the second positioning rod 52 are opposite. A rotation groove 36 is provided on the crossbar 3 in the area between the first receiving groove 321 and the second receiving groove 331 for the first positioning rod 51 and the second positioning rod 52 to rotate into and out. The end of the first positioning rod 51 away from the wave deflector 11 rotates in the rotation groove 36, and the end of the second positioning rod 52 away from the wave deflector 11 rotates in the rotation groove 36. The positioning groove 53 on the first positioning rod 51 and the positioning groove 53 on the second positioning rod 52 correspond one-to-one. The driving member is located between the first positioning rod 51 and the second positioning rod 52.

[0052] For example, the driving component includes a first toothed rod 54 and a second toothed rod 55, which are respectively slidably disposed within the crossbar 3. The first toothed rod 54 and the second toothed rod 55 slide towards each other along the length direction of the crossbar 3. A first positioning rod 51 is provided with a first gear 511 that meshes with the first toothed rod 54. A second positioning rod 52 is provided with a second gear 521 that meshes with the second toothed rod 55. After the first toothed rod 54 and the second toothed rod 55 slide and abut against each other, the first positioning rod 51 rotates upward and the second positioning rod 52 rotates downward, so that the wall of the through hole 12 of the wave deflector 11 is engaged with the positioning groove 53.

[0053] In this embodiment, the first toothed rod 54 and the second toothed rod 55 slide along the length of the transverse column 3 within the rotating groove 36. The ends of the first toothed rod 54 and the second toothed rod 55 that abut against each other have magnetic blocks, which can fix the abutting state of the first toothed rod 54 and the second toothed rod 55, thereby fixing the state in which the wall of the through hole 12 of the anti-surge plate 11 is located within the positioning groove 53. The first positioning rod 51 is rotatably connected to the transverse column 3 via the first gear 511. The second positioning rod 52 is rotatably connected to the transverse column 3 via the second gear 521. The rotation axis of the first gear 511 and the rotation axis of the second gear 521 are parallel, and the rotation axis of the first gear 511 is parallel to the rotation axes of the first robotic arm 41 and the second robotic arm 42 within the receiving groove. During the process of the first toothed rod 54 and the second toothed rod 55 sliding towards each other until they abut against each other, the first toothed rod 54 drives the first positioning rod 51 to rotate upwards, and the second toothed rod 55 drives the second positioning rod 52 to rotate downwards.

[0054] For example, the first motor 34 is coaxially connected to the first lead screw 341 through the output shaft of the first rotating column 32, and the second motor 35 is coaxially connected to the second lead screw 351 through the output shaft of the second rotating column 33. The first lead screw 341 is threaded to the inside of the end of the first gear 54 away from the second gear 55, and the second lead screw 351 is threaded to the inside of the end of the second gear 55 away from the first gear 54. When the first gear 54 and the second gear 55 abut against each other, the first lead screw 341 disengages from the threaded connection of the first gear 54, and the second lead screw 351 disengages from the threaded connection of the second gear 55.

[0055] In this embodiment, the first lead screw 341 is the output shaft of the first motor 34. The second lead screw 351 is the output shaft of the second motor 35. The first lead screw 341 and the first rotating column 32 rotate synchronously, and the second lead screw 351 and the second rotating column 33 rotate synchronously. The end of the first lead screw 341 is threaded into the interior of the first toothed rod 54. The end of the second lead screw 351 is threaded into the interior of the second toothed rod 55. When the first toothed rod 54 and the second toothed rod 55 abut against each other, the co-rotation of the first lead screw 341 and the second lead screw 351 causes the ends of the attracted first toothed rod 54 and the second toothed rod 55 to slide against the ends of the first lead screw 341 and the second lead screw 351, respectively. This allows the first lead screw 341 and the first rotating column 32 to drive the first robotic arm 41 to rotate, and the second lead screw 351 and the second rotating column 33 to drive the second robotic arm 42 to rotate, thus achieving the welding of the edge of the anti-wave plate 11 while the first positioning rod 51 and the second positioning rod 52 still position and fix the anti-wave plate 11.

[0056] It should be noted that a pair of clearance grooves 37 are provided in the horizontal column 3, which are connected to the rotating grooves 36, respectively corresponding to the first toothed rod 54 and the second toothed rod 55. This allows the first toothed rod 54 to be re-threaded to the first lead screw 341 and the second toothed rod 55 to be re-threaded to the second lead screw 351 after the first toothed rod 54 and the second toothed rod 55 are disengaged. This allows the first toothed rod 54 and the second toothed rod 55 to slide into the clearance grooves 37, so that the first rotating column 32 and the second rotating column 33 can rotate in opposite directions at a larger angle. This increases the angle of the first robotic arm 41 and the second robotic arm 42 rotating in opposite directions, and increases the welding range of the first robotic arm 41 and the second robotic arm 42 at the connection between the baffle plate 11 and the tank body 1.

[0057] The implementation principle of the anti-surge plate welding device for a mining sprinkler truck according to this application embodiment is as follows: When the first robotic arm 41 and the second robotic arm 42 are respectively located on both sides of the anti-surge plate 11 and unfolded, the first motor 34 drives the first toothed rod 54 to move towards the second toothed rod 55, and the second motor 35 drives the second toothed rod 55 to move towards the first toothed rod 54, so as to drive the first positioning rod 51 to rotate upward and the second positioning rod 52 to rotate downward, so that the first positioning rod 51 and the second positioning rod 52 located in the through hole 12 are engaged with the hole wall of the through hole 12 of the anti-surge plate 11 through the positioning groove 53, so as to restrict the anti-surge plate 11 from shifting or rotating in the tank body 1 by the symmetrical positioning of the first positioning rod 51 and the second positioning rod 52. When the two sides of the anti-surge plate 11 are welded by the first robotic arm and the second robotic arm respectively, the anti-surge plate 11 is positioned and fixed instead of manual welding, thereby reducing the welding risks of the anti-surge plate 11 and improving the welding efficiency.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
