Description

Technical Field

[0001] The utility model belongs to the technical field of water pressure testing machines, and in particular relates to an automatic paint spraying and marking device for a multi-station water pressure testing machine. Background Art

[0002] During the water test of the hydraulic press, qualified pipes and unqualified pipes will appear. The unqualified pipes that are leaking and the qualified pipes will be automatically sprayed in different colors. According to the program settings, the painting operation will be completed after the water pressure test is completed. For the automatic painting and marking process, the set lower pressure limit is used as the standard. If the pressure is lower than the lower limit during the pressure test, it will be automatically judged as scrapped and painted as an unqualified pipe. We have set protection delays for qualified and unqualified pipes. When testing the water pressure, if the pipe cannot maintain pressure within the set time due to leakage during the high-pressure test, the path of the workstation will be automatically closed, and other steel pipes will continue to complete the test. The test will automatically stop after completion.

[0024] In this technical solution, if Figure 1-4 As shown, the automatic paint marking device of the multi-station water pressure testing machine includes a device body 1, multiple output ends of the device body 1 are respectively provided with multiple paint spray tubes 2, the output ends of the paint spray tubes 2 are installed with nozzles 3, and a limiting mechanism 4 is arranged on the outer side of the device body 1, and the limiting mechanism 4 is used to prevent the multiple paint spray tubes 2 from being entangled with each other.

[0025] The limiting mechanism 4 includes a disassembly assembly and a limiting frame assembly.

[0026] The limiting frame assembly is detachably connected to the device body 1 through a disassembly assembly assembly.

[0027] The installed limiting frame assembly is used to prevent multiple paint spray tubes 2 from being entangled with each other.

[0028] Please refer to Figure 2-3 The disassembly and assembly components include a fixing frame 401, a dovetail groove 402, a screw hole 403, a bolt 404 and a dovetail piece 405.

[0029] The fixing frame 401 is fixedly connected to one side of the device body 1, the dovetail groove 402 is opened on the outside of the fixing frame 401 and extends toward the inside thereof, the dovetail piece 405 is slidably connected to the inside of the dovetail groove 402, and the inner wall of the dovetail groove 402 coincides with the outer wall of the dovetail piece 405, the screw hole 403 passes through the inside of the dovetail piece 405 and the fixing frame 401 in sequence, and the bolt 404 is threadedly connected to the screw hole 403.

[0030] Based on the above embodiment, by inserting the dovetail piece 405 into the dovetail groove 402, the dovetail groove 402 and the dovetail piece 405 in the engaged state pre-connect the fixing frame 401 and the connecting rod 406. Since the inner wall of the dovetail groove 402 coincides with the outer wall of the dovetail piece 405, the dovetail piece 405 is engaged in the dovetail groove 402 and is relatively stable. Then, the bolt 404 is threadedly connected to the screw hole 403. The tightened bolt 404 fastens the fixing frame 401 and the connecting rod 406 in the pre-connected state, and then the installation of the limit frame 407 is completed.

[0031] Please refer to Figure 3 The limiting frame assembly includes a connecting rod 406, a limiting frame 407, a U-shaped groove 408, a flap 409, a bracket 4010, a connecting shaft 4011 and a torsion spring 4012.

[0032] One end of the connecting rod 406 is fixedly connected to the dovetail piece 405, and the limit frame 407 is fixedly connected to the other end of the connecting rod 406. The U-shaped groove 408 is opened on one side of the limit frame 407 and completely penetrates the limit frame 407. The bracket 4010 is fixedly connected to both sides of the top inner wall of the U-shaped groove 408. The connecting shaft 4011 is formed at both ends of the flap 409, and the connecting shaft 4011 is rotatably connected to the brackets 4010 on both sides of the top inner wall of the U-shaped groove 408. The torsion spring 4012 is sleeved on the surface of the connecting shaft 4011 and the two ends are respectively engaged with the flap 409 and the bracket 4010. On this basis, the twisted torsion spring 4012 is used to drive the flap 409 to rotate outward and reset.

[0033] Based on the above embodiment, a paint spray tube 2 is placed inside a U-shaped groove 408. During the insertion of the paint spray tube 2, the surface of the paint spray tube 2 first squeezes the two flaps 409, so that the two flaps 409 rotate inwardly with the two connecting shafts 4011 as the center, and the two torsion springs 4012 are squeezed so that the two flaps 409 rotating inwardly open the top opening of the U-shaped groove 408, thereby facilitating the placement of a paint spray tube 2 inside a U-shaped groove 408. When the paint spray tube 2 is placed, the pressure of the two torsion springs 4012 disappears, so that the two torsion springs 4012 in the reset state respectively drive the two flaps 409 to rotate outwardly and reset, and the two flaps 409 rotating outwardly close the top opening of the U-shaped groove 408, thereby limiting the paint spray tube 2 inside a U-shaped groove 408.

[0034] Please refer to Figure 3 The two flaps 409 rotated inwardly are used to open the top opening of the U-shaped groove 408, and the two flaps 409 rotated outwardly are used to close the top opening of the U-shaped groove 408.

[0035] In this embodiment: the two flaps 409 rotated inwardly open the top opening of the U-shaped groove 408, thereby facilitating the placement of a paint spray tube 2 inside a U-shaped groove 408, and the two flaps 409 rotated outwardly close the top opening of the U-shaped groove 408, thereby confining a paint spray tube 2 inside a U-shaped groove 408.

[0036] Specifically, first, the dovetail piece 405 is inserted into the dovetail groove 402, so that the dovetail groove 402 in the engaged state and the dovetail piece 405 pre-connect the fixing frame 401 and the connecting rod 406. Since the inner wall of the dovetail groove 402 coincides with the outer wall of the dovetail piece 405, the dovetail piece 405 is relatively stable when it is engaged in the dovetail groove 402. Then, the bolt 404 is used to thread the screw hole 403. The tightened bolt 404 fastens the fixing frame 401 and the connecting rod 406 in the pre-connected state, and then the installation of the limit frame 407 is completed. At this time, a paint spraying tube 2 is placed in a U-shaped groove 408. During the insertion of a paint spraying tube 2, the surface of the paint spraying tube 2 first squeezes the two flaps 409, so that the two flaps 409 rotate inwardly with the two connecting shafts 4011 as the center, and squeezes the two torsion springs 4012 to make the inward rotation state. The two flaps 409 in the reset state open the top opening of the U-shaped groove 408, thereby facilitating the placement of a paint spray tube 2 inside a U-shaped groove 408. When a paint spray tube 2 is placed, the pressure of the two torsion springs 4012 disappears, so that the two torsion springs 4012 in the reset state respectively drive the two flaps 409 to rotate outward and reset, and the two flaps 409 rotating outward close the top opening of the U-shaped groove 408, thereby limiting a paint spray tube 2 inside a U-shaped groove 408. Since there are multiple U-shaped grooves 408 and paint spray tubes 2, as described above, the multiple paint spray tubes 2 are respectively limited in the multiple U-shaped grooves 408 in turn, so that the multiple paint spray tubes 2 are arranged in order to prevent the multiple paint spray tubes 2 from being entangled with each other, and when a paint spray tube 2 is needed for paint marking, the paint spray tube 2 can be taken out from the U-shaped groove 408.
