Description

Technical Field

[0001] The present application relates to the technical field of welding and assembling of water sprinkler tanks, and in particular to a welding device for anti-surge plates of mine water sprinklers. Background Art

[0002] Mine water sprinklers are important dust reduction and temperature reduction equipment in mine operations. Anti-surge plates are usually installed inside the tank to reduce the sloshing of the liquid during transportation, thereby improving the driving stability of the vehicle. The anti-surge plates usually have an arc-shaped or special-shaped structure and need to be welded and fixed at specific positions inside the tank, and the welding accuracy requirements are relatively high to ensure the fitting degree and connection strength between the anti-surge plate and the tank wall. Currently, for the welding operation of anti-surge plates of mine water sprinklers, traditional processes mostly adopt manual welding methods: operators need to enter the tank and weld the fitting parts of the anti-surge plate and the tank by holding a welding torch. However, this welding method is not only dangerous but also has low efficiency and needs to be improved. Summary of the Invention

[0003] In order to reduce the welding hazards of anti-surge plates and improve the welding efficiency, the present application provides a welding device for anti-surge plates of mine water sprinklers.

[0004] A welding device for anti-surge plates of mine water sprinklers provided by the present application includes a support platform for receiving the water sprinkler tank. A plurality of anti-surge plates are arranged inside the tank. The anti-surge plates include a middle through hole and edge holes. The device further includes: a column, on which a lifting mechanism and a transverse movement mechanism are arranged; a cross column, slidably arranged on the column, and one end of the cross column away from the column extends into the through hole of the anti-surge plate. The lifting mechanism is used to drive the cross column to slide vertically on the column, and the transverse movement mechanism is used to drive the cross column to slide horizontally on the column; a welding mechanism, rotatably arranged at one end of the cross column away from the column, and the rotation axis extends along the axis direction of the through hole of the anti-surge plate; a positioning mechanism, arranged on the column near the welding mechanism and located inside the through hole, and used to position and fix the anti-surge plate inside the tank.

[0005] By adopting the above technical solution, when welding the wave baffle to the tank body, first weld the wave baffle to the inside of the tank body so as to place the tank body and the wave baffle on the support table together. Then, the lifting mechanism on the column drives the cross column to move in the vertical direction to the center of the tank opening of the tank body. Then, the transverse movement mechanism drives the cross column to move towards the inside of the tank body until the positioning mechanism on the cross column is located in the through hole of the wave baffle to position the wave baffle, so as to fix the wave baffle in the tank body, so that the welding mechanism can weld the connection between the wave baffle and the tank body along one circle of the wave baffle. Such a setting, through the cooperation of the lifting mechanism and the transverse movement mechanism, enables the welding mechanism to weld when the positioning mechanism positions and fixes the wave baffle in the tank body, instead of manually positioning and fixing the wave baffle during welding, thereby reducing the welding hidden danger of the wave baffle and improving the welding efficiency.

[0006] Optionally, the welding mechanism includes a first manipulator and a second manipulator rotatably arranged on the cross column. The first manipulator and the second manipulator are symmetrically arranged on both sides of the wave baffle. The ends of the first manipulator and the second manipulator are provided with welding torches, and the welding torches are used to weld both sides of the connection between the wave baffle and the tank body.

[0007] By adopting the above technical solution, when welding the connection between the wave baffle and the tank body, the cross column moves into the through hole of the wave baffle in the tank body, so that the first manipulator and the second manipulator are respectively located on both sides of the wave baffle, the welding torch on the first manipulator faces one side of the wave baffle, and the welding torch on the second manipulator faces the other side of the wave baffle, so as to realize the simultaneous welding of the connections on both sides of the wave baffle and improve the welding efficiency.

[0008] Optionally, a first rotating column connected to the first manipulator and a second rotating column connected to the second manipulator are respectively rotatably arranged on the cross column. The rotation axes of the first rotating column and the second rotating column are parallel to the axis direction of the through hole of the wave baffle. The first rotating column and the second rotating column rotate on the upper side of the cross column, and the lower side of the cross column corresponding to the edge holes of the wave baffle is located below the first rotating column and the second rotating column.

[0009] By adopting the above technical solution, when welding along the connection of one circle of the wave baffle, since the wave baffle has edge holes, the first manipulator can weld the connection between the wave baffle and the tank body without rotating one circle under the rotation of the first rotating column, and the second manipulator can weld the connection between the wave baffle and the tank body without rotating one circle under the rotation of the second rotating column, so as to facilitate the first manipulator and the second manipulator to weld along the edge of the wave baffle.

[0010] Optionally, a first motor for driving the first rotating column to rotate and a second motor for driving the second rotating column to rotate are arranged on the cross column.

[0011] By adopting the above technical solution, it is convenient for the first motor to drive the first rotating column to drive the first manipulator to weld along a circle of the wave breaker, and it is convenient for the second motor to drive the second rotating column to drive the second manipulator to weld along a circle of the wave breaker.

[0012] Optionally, a first receiving groove for the first manipulator to be folded and deformed into is formed on the first rotating column, and a second receiving groove for the second manipulator to be folded and deformed into is formed on the second rotating column.

[0013] By adopting the above technical solution, when the cross column enters the through hole of the tank body to the wave breaker, the first manipulator can be deformed and folded into the first receiving groove, and the second manipulator can be deformed and folded into the second receiving groove. Until the cross column enters and the first manipulator and the second manipulator are respectively located on both sides of the wave breaker, the first manipulator is deformed and unfolded from the first receiving groove, and the second manipulator is deformed and unfolded from the second receiving groove, so as to facilitate the storage of the first manipulator and the second manipulator and reduce the volume of the cross column.

[0014] Optionally, the positioning mechanism includes: a first positioning rod rotatably arranged on the cross column between the first manipulator and the second manipulator; a second positioning rod rotatably arranged on the cross column between the first manipulator and the second manipulator; a driving member arranged in the cross column to respectively drive the first positioning rod to rotate upward and drive the second positioning rod to rotate downward; wherein, the rotation axes of the first positioning rod and the second positioning rod are both perpendicular to the length directions of the upright column and the cross column, the first positioning rod and the second positioning rod are symmetrically arranged along the length direction of the cross column, and positioning grooves are formed on both the first positioning rod and the second positioning rod, and the positioning grooves are for the hole wall of the through hole of the wave breaker to be inserted into.

[0015] By adopting the above technical solution, when the first manipulator and the second manipulator are respectively located on both sides of the wave breaker and unfolded, the driving member drives the first positioning rod to rotate upward and the second positioning rod to rotate downward, so that the first positioning rod and the second positioning rod located in the through hole are clamped with the hole wall of the through hole of the wave breaker through the positioning grooves, so as to facilitate the upper and lower symmetrical clamping of the first positioning rod and the second positioning rod to limit the offset or rotation of the wave breaker in the tank body, thereby ensuring the stability of the wave breaker welding.

[0016] Optionally, the driving member includes a first rack and a second rack respectively slidably arranged in the cross column, the first rack and the second rack slide towards each other along the length direction of the cross column, a first gear meshing with the first rack is arranged on the first positioning rod, a second gear meshing with the second rack is arranged on the second positioning rod, and after the first rack and the second rack slide towards each other and abut, the first positioning rod rotates upward and the second positioning rod rotates downward, for the hole wall of the through hole of the wave breaker to be inserted into the positioning groove.

[0017] By adopting the above technical solution, when driving the first positioning rod and the second positioning rod to rotate, the first rack and the second rack slide towards each other, so that the first rack drives the first gear to rotate counterclockwise, driving the first positioning rod to rotate upward, so that the second rack drives the second gear to rotate clockwise, driving the second positioning rod to rotate downward, until the first positioning rod and the second positioning rod are clamped with the hole wall of the through hole of the wave baffle through the positioning groove, realizing the positioning and fixing of the wave baffle, thereby completing the reverse rotation of the first positioning rod and the second positioning rod to realize the positioning and fixing of the wave baffle.

[0018] Optionally, the output shaft of the first motor passing through the first rotating column is coaxially connected with a first lead screw, and the output shaft of the second motor passing through the second rotating column is coaxially connected with a second lead screw. The first lead screw is threadedly connected to the inside of one end of the first rack away from the second rack, and the second lead screw is threadedly connected to the inside of one end of the second rack away from the first rack. When the first rack and the second rack are in contact with each other, the first lead screw disengages from the threaded connection of the first rack, and the second lead screw disengages from the threaded connection of the second rack.

[0019] By adopting the above technical solution, when the first motor drives the first rotating column and the first manipulator to rotate, and the second motor drives the second rotating column to drive the second manipulator 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 are in contact with each other. At this time, the first positioning rod and the second positioning rod are clamped with the inner wall of the through-hole of the wave baffle, completing the positioning and fixing of the wave baffle. However, at this time, the first motor continues to drive the first rotating column, the first lead screw, and the first manipulator to rotate, and the second motor continues to drive the second rotating column, the second lead screw, and the second manipulator to rotate to weld the entire circumference of the wave baffle to the tank body. After the welding is completed, the lifting mechanism drives the cross-column to move upward. While the reaction force of the wave baffle acts on the first positioning rod and pushes the first positioning rod downward, the first motor drives the first lead screw to rotate in the reverse direction so that the first lead screw and the first toothed rod are threadedly connected again. In order to separate the first toothed rod and the second toothed rod under the reverse rotation of the first lead screw, and the first positioning rod rotates downward and disengages from the inner wall of the through-hole of the wave baffle; then the lifting mechanism drives the cross-column to move downward. While the reaction force of the wave baffle acts on the second positioning rod and pushes the second positioning rod upward, the second motor drives the second lead screw to rotate in the reverse direction so that the second lead screw and the second toothed rod are threadedly connected again. In order to further separate the second toothed rod from the first toothed rod under the reverse rotation of the second lead screw, and the second positioning rod rotates upward and disengages from the inner wall of the through-hole of the wave baffle. In this way, by driving the cross-column to move up and down by the lifting mechanism, the reaction force of the wave baffle acts on the first positioning rod and the second positioning rod, and under the rotational cooperation of the first lead screw and the second lead screw, they are respectively threadedly connected to the first toothed rod and the second toothed rod again, realizing the automatic release of the positioning and fixing of the wave baffle, thus facilitating the withdrawal of the cross-column, the first manipulator, and the second manipulator from the tank body and the wave baffle.

[0020] Optionally, the lifting mechanism includes: a lifting slider slidably connected to the cross-column in the horizontal direction; a screw rod penetrating and threadedly connected to the lifting slider in the vertical direction, the axis of rotation of the screw rod extending in the vertical direction; a lifting motor disposed at the top of the column and coaxially connected to the screw rod.

[0021] By adopting the above technical solution, when driving the cross-column to move up and down, the lifting motor drives the screw rod to rotate. After the screw rod rotates, it drives the lifting slider to move up and down in the vertical direction. At the same time, the lifting slider drives the cross-column to move up and down in the vertical direction, and the lifting slider slides within the cross-column so that when the cross-column moves horizontally, the lifting slider maintains the threaded connection with the screw rod.

[0022] Optionally, vertical tooth patterns are provided on the side wall of the cross column. The transverse movement mechanism includes: a driving gear that rotates inside the column and meshes with the tooth patterns; a driving rod coaxially connected to the driving gear, with the rotation axis of the driving rod extending in the vertical direction; and a transverse movement motor disposed at the top of the column and coaxially connected to the driving rod.

[0023] By adopting the above technical solution, when the cross column slides horizontally into and out of the tank body, the transverse movement motor drives the driving rod to rotate, the driving rod drives the driving gear to rotate, and the driving gear drives the cross column to slide horizontally through meshing with the tooth patterns, so as to facilitate the feeding and discharging of the first manipulator and the second manipulator into and out of the tank body.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: Through the cooperation of the lifting mechanism and the transverse movement mechanism, the welding mechanism performs welding when the positioning mechanism positions and fixes the wave baffle in the tank body, so as to replace the manual welding for positioning and fixing the wave baffle, reduce the welding hidden danger of the wave baffle and improve the welding efficiency; The first positioning rod and the second positioning rod are clamped with the hole wall of the through hole of the wave baffle through the positioning groove, so as to limit the offset or rotation of the wave baffle in the tank body through the upper and lower symmetric clamping of the first positioning rod and the second positioning rod, thereby ensuring the stability of the wave baffle welding; The lifting mechanism drives the cross column to move up and down, so that the reaction force of the wave baffle acts on the first positioning rod and the second positioning rod, and under the rotational cooperation of the first lead screw and the second lead screw, they are respectively re-threaded with the first tooth rod and the second tooth rod, realizing the automatic release of the positioning and fixing of the wave baffle, so as to facilitate the evacuation of the cross column, the first manipulator, and the second manipulator from the tank body and the wave baffle.

Detailed implementation mode

[0031] The following is further detailed description of the present application in conjunction with the attached Figures 1-5 drawings.

[0032] Referring to Figure 1 and Figure 2 , an anti-rolling plate welding device for a mine sprinkler truck disclosed in an embodiment of the present application includes a support platform 6 for receiving the tank body 1 of the sprinkler truck. A plurality of anti-rolling plates 11 are arranged in the tank body 1. The anti-rolling plate 11 includes a middle through hole 12 and an edge hole 13. The plurality of anti-rolling plates 11 are evenly spaced along the length of the tank body 1. And before the tank body 1 is placed on the support platform 6, the bottom wall of the anti-rolling plate 11 near the edge hole 13 has been spot-welded to the inner wall of the tank body 1 to form a preliminary positioning, so that the anti-rolling plate 11 can be placed on the support platform 6 in a state where the edge hole 13 is placed at the lower end of the tank body 1 for the welding device to perform welding.

[0033] The welding device includes a vertical column 2, a transverse column 3, a welding mechanism 4 and a positioning mechanism 5 (the welding mechanism 4 and the positioning mechanism 5 are in Figure 4 ). A lifting mechanism 21 and a transverse movement mechanism 22 are arranged on the vertical column 2; the transverse column 3 is slidably arranged on the vertical column 2, and one end of the transverse column 3 away from the vertical column 2 extends into the through hole 12 of the anti-rolling plate 11. The lifting mechanism 21 is used to drive the transverse column 3 to slide vertically on the vertical column 2, and the transverse movement mechanism 22 is used to drive the transverse column 3 to slide horizontally on the vertical column 2; the welding mechanism 4 is rotatably arranged at one end of the transverse column 3 away from the vertical column 2, and the rotation axis extends along the axis direction of the through hole 12 of the anti-rolling plate 11; the positioning mechanism 5 is arranged on the vertical column 2 near the welding mechanism 4 and is located in the through hole 12, and is used to position and fix the anti-rolling plate 11 in the tank body 1.

[0034] In this embodiment, one end of the horizontal column 3 slides horizontally through the vertical column 2, and the other end extends into the tank body 1. As the horizontal column 3 slides horizontally, the horizontal column 3 drives the welding device and the positioning device to weld multiple anti-rolling plates 11 in the tank body 1 in sequence. Specifically, welding can be carried out sequentially through the through holes 12 in the anti-rolling plates 11.

[0035] In some embodiments, referring to Figure 2 and Figure 3 , the lifting mechanism 21 includes a lifting slider 211, a screw rod 212, and a lifting motor 213. The lifting slider 211 is slidably connected to the inside of the horizontal column 3 in the horizontal direction; the screw rod 212 penetrates and is threadedly connected to the inside of the lifting slider 211 in the vertical direction, and the rotation axis of the screw rod 212 extends in the vertical direction; the lifting motor 213 is arranged at the top end of the vertical column 2 and is coaxially connected to the screw rod 212.

[0036] In this embodiment, the lifting motor 213 is fixed to the top wall of the vertical column 2, and the screw rod 212 coaxially connected to the lifting motor 213 vertically penetrates the lifting slider 211 and is threadedly connected. The lifting slider 211 is slidably connected to the horizontal column 3 through a T-shaped sliding connection, so as to realize that the horizontal column 3 still maintains a sliding connection with the lifting slider 211 during horizontal sliding, 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 rod 212 rotates.

[0037] In some embodiments, a row of vertical tooth patterns 31 are provided on the side wall of the horizontal column 3. The transverse movement mechanism 22 includes a driving gear 221, a driving rod 222, and a transverse movement motor 223. The driving gear 221 rotates inside the vertical column 2 and meshes with the tooth patterns 31; the driving rod 222 is coaxially connected to the driving gear 221, and the rotation axis of the driving rod 222 extends in the vertical direction; the transverse movement motor 223 is arranged at the top end of the vertical column 2 and is coaxially connected to the driving rod 222.

[0038] In this embodiment, the transverse movement motor 223 and the lifting motor 213 are arranged side by side and fixed to the top wall of the vertical column 2. The driving rod 222 and the screw rod 212 are arranged in parallel. The tooth patterns 31 are arranged opposite to the lifting slider 211. The driving rod 222 rotates inside the vertical column 2 to drive the driving gear 221 to rotate, so that the horizontal column 3 slides in the horizontal direction as the driving gear 221 rotates due to the meshing of the tooth patterns 31 and the driving gear 221.

[0039] In some embodiments, referring to Figure 4 , the welding mechanism 4 includes a first manipulator 41 and a second manipulator 42 rotatably arranged on the horizontal column 3. The first manipulator 41 and the second manipulator 42 are symmetrically arranged on both sides of the anti-rolling plate 11. The ends of the first manipulator 41 and the second manipulator 42 are provided with welding torches, and the welding torches are used to weld both sides of the connection between the anti-rolling plate 11 and the tank body 1.

[0040] In this embodiment, both the first manipulator 41 and the second manipulator 42 have joints that can move freely, so that after the cross-column 3 slides into the through-hole 12 of the wave baffle 11, the first manipulator 41 and the second manipulator 42 are respectively located on both sides of the wave baffle 11. The first manipulator 41 and the second manipulator 42 can be symmetrically arranged along the wave baffle 11 or asymmetrically arranged. The first manipulator 41 and the second manipulator 42 can be programmed to set parameters to weld both sides of the wave baffle 11, realizing spot welding in the circumferential direction of the wave baffle 11.

[0041] In some embodiments, a first rotating column 32 connected to the first manipulator 41 and a second rotating column 33 connected to the second manipulator 42 are respectively rotatably provided on the cross-column 3. The rotation axes of the first rotating column 32 and the second rotating column 33 are parallel to the axis direction of the through-hole 12 of the wave baffle 11. The first rotating column 32 and the second rotating column 33 rotate on the upper side of the cross-column 3, and the lower side of the cross-column 3 where the first rotating column 32 and the second rotating column 33 are located corresponds to the edge hole 13 of the wave baffle 11.

[0042] In this embodiment, the rotation axes of the first rotating column 32 and the second rotating column 33 both extend along the length direction of the cross-column 3. The first rotating column 32 and the second rotating column 33 are both rotatably connected to the upper end portion of the cross-column 3, so that the lower end portion of the cross-column 3 is connected to support the positioning mechanism 5, realizing that the first manipulator 41 and the second manipulator 42 are respectively located on both sides of the wave baffle 11. The rotation blind areas of the first rotating column 32 and the second rotating column 33 driving the first manipulator 41 and the second manipulator 42 respectively are exactly the places where the lower edge hole 13 of the wave baffle 11 does not need to be welded.

[0043] In some embodiments, 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 are provided on the cross-column 3. The first motor 34 is located on the side of the first rotating column 32 away from the wave baffle 11, and the second motor 35 is located on the side of the second rotating column 33 away from the wave baffle 11.

[0044] In some embodiments, a first receiving groove 321 for the first manipulator 41 to be folded and deformed and received is provided on the first rotating column 32, and a second receiving groove 331 for the second manipulator 42 to be folded and deformed and received is provided on the second rotating column 33.

[0045] In some embodiments, referring 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 cross-column 3 between the first manipulator 41 and the second manipulator 42; the second positioning rod 52 rotates on the cross-column 3 between the first manipulator 41 and the second manipulator 42; the driving member is arranged in the cross-column 3 to respectively drive the first positioning rod 51 to rotate upward and drive the second positioning rod 52 to rotate downward.

[0046] Among them, the rotation axes of the first positioning rod 51 and the second positioning rod 52 are both perpendicular to the length directions of the vertical 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. Positioning grooves 53 are formed on both the first positioning rod 51 and the second positioning rod 52, and the through-hole 12 hole walls of the wave guard plate 11 are inserted into the positioning grooves 53.

[0047] In this embodiment, the first positioning rod 51 and the second positioning rod 52 are symmetrically arranged about the center of the through-hole 12 of the wave guard plate 11. The rotation directions of the first positioning rod 51 and the second positioning rod 52 are opposite. A rotation groove 36 for the first positioning rod 51 and the second positioning rod 52 to rotate in and out is formed in the area of the horizontal column 3 between the first receiving groove 321 and the second receiving groove 331. The end of the first positioning rod 51 away from the wave guard plate 11 rotates in the rotation groove 36, and the end of the second positioning rod 52 away from the wave guard plate 11 rotates in the rotation groove 36. The positioning grooves 53 on the first positioning rod 51 and the positioning grooves 53 on the second positioning rod 52 correspond one by one. The driving member is located between the first positioning rod 51 and the second positioning rod 52.

[0048] Exemplarily, the driving member includes a first rack 54 and a second rack 55 that are respectively slidably arranged in the horizontal column 3. The first rack 54 and the second rack 55 slide towards each other along the length direction of the horizontal column 3. A first gear 511 meshing with the first rack 54 is provided on the first positioning rod 51. A second gear 521 meshing with the second rack 55 is provided on the second positioning rod 52. After the first rack 54 and the second rack 55 slide towards each other and abut, the first positioning rod 51 rotates upward and the second positioning rod 52 rotates downward, for the through-hole 12 hole walls of the wave guard plate 11 to be inserted into the positioning grooves 53.

[0049] In this embodiment, the first rack 54 and the second rack 55 slide in the rotation groove 36 along the length direction of the horizontal column 3. And the end parts of the first rack 54 and the second rack 55 in contact with each other have magnetic blocks, which can fix the state of the first rack 54 and the second rack 55 in contact with each other, and further fix the state of the through-hole 12 hole walls of the wave guard plate 11 in the positioning grooves 53. The first positioning rod 51 is rotationally connected to the horizontal column 3 through the first gear 511. The second positioning rod 52 is rotationally connected to the horizontal column 3 through 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 and the rotation axes of the first manipulator 41 and the second manipulator 42 in the receiving groove are parallel. During the process of the first rack 54 and the second rack 55 sliding towards each other until they abut, the first rack 54 drives the first positioning rod 51 to rotate upward, and the second rack 55 drives the second positioning rod 52 to rotate downward.

[0050] Exemplarily, a first lead screw 341 is coaxially connected to the output shaft of a first motor 34 passing through a first rotating column 32, and a second lead screw 351 is coaxially connected to the output shaft of a second motor 35 passing through a second rotating column 33. The first lead screw 341 is threadedly connected to the inside of one end of a first toothed rod 54 away from a second toothed rod 55, and the second lead screw 351 is threadedly connected to the inside of one end of the second toothed rod 55 away from the first toothed rod 54. When the first toothed rod 54 and the second toothed rod 55 are in contact with each other, the first lead screw 341 disengages from the threaded connection with the first toothed rod 54, and the second lead screw 351 disengages from the threaded connection with the second toothed rod 55.

[0051] 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 threadedly connected to the inside of the first toothed rod 54. The end of the second lead screw 351 is threadedly connected to the inside of the second toothed rod 55. When the first toothed rod 54 and the second toothed rod 55 are in contact with each other, the co-rotation of the first lead screw 341 and the second lead screw 351 causes the end portions of the first toothed rod 54 and the second toothed rod 55 that have already attracted each other to slide and contact the end portion of the first lead screw 341 and the end portion of the second lead screw 351 respectively. So that under the drive of the first lead screw 341 and the first rotating column 32 to drive the first manipulator 41 to rotate and the second lead screw 351 and the second rotating column 33 to drive the second manipulator 42 to rotate, while welding the edge of the wave guard 11, the first positioning rod 51 and the second positioning rod 52 still position and fix the wave guard 11.

[0052] It should be noted that a pair of relief grooves 37 communicating with the rotating grooves 36 are formed in the cross column 3, corresponding to the first toothed rod 54 and the second toothed rod 55 respectively. So that after the first toothed rod 54 and the second toothed rod 55 are separated, the first toothed rod 54 is threadedly connected to the first lead screw 341 again, and the second toothed rod 55 is threadedly connected to the second lead screw 351 again, enabling the first toothed rod 54 and the second toothed rod 55 to slide into the relief grooves 37, so as to supply the first rotating column 32 and the second rotating column 33 to rotate reversely by a larger angle, thereby increasing the reverse rotation angle of the first manipulator 41 and the second manipulator 42, and increasing the welding range of the first manipulator 41 and the second manipulator 42 at the connection between the wave guard 11 and the tank body 1.

[0053] The implementation principle of the anti-wave plate welding device for a mine sprinkler truck in an embodiment of the present application is as follows: When the first manipulator 41 and the second manipulator 42 are respectively located on both sides of the anti-wave 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 clamped with the hole wall of the through hole 12 of the anti-wave plate 11 through the positioning groove 53, so as to facilitate the upper and lower symmetrical positioning of the first positioning rod 51 and the second positioning rod 52 to limit the anti-wave plate 11 from shifting or rotating in the tank body 1. When welding both sides of the anti-wave plate 11 by the first manipulator and the second manipulator respectively, the anti-wave plate 11 is positioned and fixed instead of manual welding, thereby reducing the welding hidden danger of the anti-wave plate 11 and improving the welding efficiency.

[0054] The above are all preferred embodiments of the present application. Without restricting the protection scope of the present application based on this, therefore: Any equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
