Description

Technical Field

[0001] The present invention relates to the field of welding and casting, and specifically to a plasma cladding surfacing device for the eye plate and cutting ring of a pump truck. Background Art

[0002] The eye plate of a pump truck, also known as the spectacle plate cutting ring, is one of the important accessories of a concrete pump truck. Its main function is to ensure the sealing performance during the concrete pumping process, prevent slurry leakage, thereby ensuring the pumping efficiency and construction quality. The cutting ring has a circular shape, and the eye plate of the pump truck has a double-circular shape. The main function of this device is to weld and join the eye ring and cutting ring of the pump truck, improving the production efficiency and quality of mechanical parts.

[0003] The existing Chinese patent with the publication number CN216370869U discloses a pump truck boom side plate assembly and welding workstation, belonging to welding equipment. A welding robot is slidably installed on a three-axis gantry, and a positioning and assembling tooling is arranged on one side of the three-axis gantry; the positioning and assembling tooling includes a tooling main body with a slide rail on it; a front linear module, a tooling component, and a rear linear module are slidably installed on the slide rail of the tooling main body; the tooling component includes a slide seat slidably installed on the slide rail of the tooling main body; a butt joint seam forming platform is liftably installed on the slide seat; a sunken groove is formed on the butt joint seam forming platform, and a pair of positioning blocks and a pair of pressing components are respectively installed on both sides of the sunken groove. This technical solution adopts an electric tooling to achieve accurate adjustment of the tooling, which can meet the welding requirements of workpieces with different lengths; adopts the method of single-sided welding with double-sided forming and a pneumatic pressing mechanism to reduce the labor intensity of workers and improve production efficiency; the tooling component and the linear module are electrically adjusted to be adaptable to workpieces of various models.

[0004] However, this pump truck boom side plate assembly and welding workstation still has the following defects: 1. During the processing of the eye plate and cutting ring on the pump truck, there are problems such as high processing costs and inability to perform batch surfacing processing. Moreover, due to their special-shaped appearance, when the sheet-shaped circular eye plate and cutting ring lie flat on the conveyor belt during transportation, it is difficult for the robotic arm to pick them up. And when the sheet-shaped circular cutting ring is transported on the conveyor belt, it will roll during the handling process and fall off the workbench surface; in addition, the heat on the surface of the metal parts after surfacing has not dissipated, and concentrating the stacked metal parts will cause the welding points on the surface of the metal parts to adhere. The organization and performance of the heat-affected zone after welding will change, which will further lead to the degradation of the overall performance of the structure, and it is prone to plastic deformation and adhesion due to heat. These deformations of the eye plate and cutting ring of the pump truck cannot be completely restored after cooling, and residual stress will be formed.

And at the middle position of the turning rod 413, it is hinged and connected to the other side of the triangular transmission rod 410 away from the third hinge point 420 through the first hinge point 418.

[0043] At the top of the material receiving claw 416, a material receiving groove 8 is provided. At the bottom of the material receiving claw 416, on the side away from the second hinge rod 408, it is hinged and connected to the third hinge rod 409. On the side of the turning rod 413 close to the material receiving claw 416, a material conveying hopper 415 is hinged and installed. And the material conveying hopper 415 has a triangular hopper-like outer shape. The turning rod 413 drives the material conveying hopper 415 to catch the pump truck eye plate template 6 transported by the material receiving claw 416.

[0044] At the discharge end of the transition transportation structure 4, a material receiving box 5 is installed. Then the turning rod 413 drives the material conveying hopper 415 to turn, transports the pump truck eye plate template 6 into the material receiving box 5. By transporting the pump truck eye plate template 6 twice, it achieves the function of transferring the pump truck eye plate template 6 and cooling the just-welded pump truck eye plate template 6 through the transferred pump truck eye plate template 6.

[0045] By using the material receiving claw 416 and the material transfer hopper 415 to transport the concrete pump truck eye plate template 6, it can achieve the function of automatically transporting the welded concrete pump truck eye plate template 6 after processing and welding, avoiding the concrete pump truck eye plate template 6 in the shape of a ring from falling off the workbench surface during the transmission process. Moreover, the heat on the surface of the just-welded concrete pump truck eye plate has not dissipated, and concentrated stacking will cause the welding points on the surface of the concrete pump truck eye plate to adhere. In addition, the stacked concrete pump truck eye plates are likely to fall off the transport table during the vibration of transportation. Additionally, cooling can reduce the changes in the structure and performance of the heat-affected zone after welding, avoiding problems such as plastic deformation and adhesion of the material due to heat. After cooling, these deformations cannot be completely restored and residual stresses will be formed. Externally, through two transfers of the concrete pump truck eye plate template 6, the concrete pump truck eye plate template 6 after welding with the high-temperature welding head 314 can be cooled down as soon as possible. And the method of transporting each group of concrete pump truck eye plate templates 6 individually during transportation makes the transportation process of the concrete pump truck eye plate template 6 more stable, avoiding adhesion during the transportation of the just-welded concrete pump truck eye plate template 6, and finally being centrally put into the receiving box 5 for centralized storage.

[0046] Working principle: First, start the rotating motor 417 through an external power supply. The rotating motor 417 drives the driving roller 404 to rotate. The rotation of the driving roller 404 drives the triangular transmission rod 410 to rotate through the third hinge point 420. The third hinge point 420 pulls the second hinge rod 408 to drive the material receiving claw 416 to move. The function of the third hinge rod 409 is to assist the movement of the material receiving claw 416. At the same time, when the triangular transmission rod 410 moves around the driving roller 404, the triangular transmission rod 410 drives the turning rod 413 to move through the first hinge point 418. The turning rod 413 drives the material transfer hopper 415 to catch the concrete pump truck eye plate template 6 transported by the material receiving claw 416, and then the turning rod 413 drives the material transfer hopper 415 to turn over, transporting the concrete pump truck eye plate template 6 into the receiving box 5. By transporting the concrete pump truck eye plate template 6 twice, it achieves the function of transferring the concrete pump truck eye plate template 6 and cooling the just-welded concrete pump truck eye plate template 6 through the transfer. This working principle demonstrates the transportation process of the double-ring concrete pump truck eye plate template 6. The transportation process of the single-ring cutting ring template 7 is the same as above.

[0047] Then, the transmission motor 302 is started by an external power supply, and the transmission motor 302 drives the first transmission roller 304 to rotate. The first transmission roller 304 drives the transmission toothed belt 305 to move through meshing transmission. The function of the protective shell 303 is to prevent dust. Then the transmission toothed belt 305 drives the connecting piece 307 to move, thereby horizontally moving the distance between the high-temperature welding head 314 and the welding point on the pump truck eye plate template 6. The external power supply starts the moving motor 308, and the moving motor 308 drives the transmission screw rod 309 to rotate. The transmission screw rod 309 drives the moving slider 310 to move. The moving slider 310 drives the adapter 311 to rise and fall, and further drives the magnetic slide rail 312 to rise and fall, thereby vertically moving the distance between the high-temperature welding head 314 and the welding point on the pump truck eye plate template 6. After the magnetic slide rail 312 is energized, the magnetic slider 313 is lifted and lowered by magnetic force, and the position of the high-temperature welding head 314 is more accurately controlled by magnetic force.

[0048] Finally, the external power supply starts the telescopic motor 202 to telescope and drive the articulated fork 203 to move, and the articulated fork 203 drives the hinged member 204 to rotate around the first fixed plug rod 205. When the hinged member 204 rotates, it drives the first connecting rod 206 and the second connecting rod 207 to move. The first connecting rod 206 drives the second triangular member 227 to flip around the fourth fixed plug rod 214. The flipping of the second triangular member 227 will drive the second movable top member 215 to move. The second movable top member 215 will drive the third fixed plug rod 211 at the top to rotate. The rotation of the third fixed plug rod 211 will drive the second support plate 213 to flip along with the third fixed plug rod 211. The second connecting rod 207 on the other side drives the first triangular member 208 to flip around the second fixed plug rod 209. The flipping of the first triangular member 208 will drive the first movable top member 210 to move. The first movable top member 210 will drive the fifth fixed plug rod 226 at the top to rotate. The rotation of the fifth fixed plug rod 226 will drive the first support plate 212 to flip along with the fifth fixed plug rod 226. In addition, when the telescopic motor 202 retracts, the second support plate 213 and the first support plate 212 will be flipped to the required position through transmission, and then the hinged fork 203 will drive the connecting rib rod 218 to flip, and the supporting side plate 219 with the connecting rib rod 218 will rotate around the conveying rod 222, and the connecting support rod 220 will slide within the range of the limiting track 224, and the supporting side plate 219 will drive the conveyor belt to tilt, and the conveying motor 223 will drive the conveying rod 222 to rotate, and the conveying rod 222 will drive the transmission roller 216, the rotating roller 221 and the side conveying crawler 217 to transmit, thereby driving the main conveying crawler 225 to receive the debris dropped during the weld.
