Description

Technical Field

[0001] The utility model belongs to the technical field of spraying mechanisms and relates to a 360-degree no-dead-angle pump casing spraying mechanism. Background Art

[0002] The pump casing is an external device of the pump device. It needs to be sprayed during the production process to protect the pump casing. The 360° no-dead-angle pump casing spraying mechanism is needed during the spraying process. A conveyor belt is provided in the no-dead-angle pump casing spraying mechanism. The pump casing is hung on the conveyor belt through the corresponding hook and moves to the manual spraying station along the conveyor belt. The worker holds the spray gun with one hand and uses the other hand to properly rotate the lifting equipment to rotate the pump casing 360 degrees. At the same time, the pump casing is properly pulled up to tilt it toward the human body, exposing the bottom of the pump casing within the field of vision, allowing workers to spray the pump casing without dead angles.

[0003] During the existing process of spraying the pump casing without dead angles, since the pump casing is simply hoisted under the conveyor belt by an ordinary hook, it is necessary to manually rotate or move the pump casing in the vertical direction during spraying, which may cause the hook and the pump casing to fall off. At the same time, the pump casing that has been sprayed cannot be directly touched by hand, and the hook hanging the pump casing is inconvenient during unloading. Utility Model Content

[0029] In this embodiment, a conveyor belt is installed horizontally on the top of the main body 1, and the long plate 21 and the short plate 22 are hoisted on the conveyor belt. As the conveyor belt moves, the hoisting equipment 2 with the pump casing hoisted is moved to the manual spraying station. During the spraying process, the pump casing will be rotated appropriately by humans, or the pump casing will be lifted appropriately to expose its bottom position to the field of vision for spraying without dead angles. In this process, it is very likely to fall off.

[0030] Combination Figure 1 , Figure 2 As shown, the long plate 21 and the short plate 22 are provided with threaded holes 53 of the same specification, and the long plate 21 and the short plate 22 are cross-arranged.

[0031] Furthermore, the long plate 21 and the short plate 22 can be fixed by using bolts in the threaded holes 53 , and the overall lifting height of the lifting equipment 2 can be changed by adjusting the intersection position of the long plate 21 and the short plate 22 .

[0032] Combination Figure 1 , Figure 2 As shown, the support rod 23 passes through the sleeve 31, the sleeve 31 and the support rod 23 are rotatably installed, and the U-shaped bracket 32 ​​is composed of three sliding rods with threads. The U-shaped bracket 32 ​​passes through the circular hole 41, the rectangular cavity 42 is connected to the side cavity 43, the rectangular cavity 42 is connected to the inner cavity 44, and the other end of the side cavity 43 is connected to the outside.

[0033] Furthermore, the hook 4 is mounted on the U-shaped bracket 32, and the U-shaped bracket 32 ​​is mounted on the gear 3, so that the hook 4 can rotate with the gear 3, so that the pump housing can be properly rotated for 360-degree spraying without dead angles when manually turned.

[0034] Combination Figure 2 , Figure 3 , Figure 4 As shown, the outer contour of the rotating block 6 is circular, the rotating block 6 is slidably connected to the inner wall of the inner cavity 44 , and one side of the rotating block 6 protrudes from the opening 45 .

[0035] Furthermore, the rotating block 6 can rotate inside the inner cavity 44 , and one side of the rotating block 6 with the socket 61 protrudes from the opening 45 , which is convenient for installing the hanging ring 51 . The size of the socket 61 is much larger than the hanging ring 51 .

[0036] Combination Figure 2 , Figure 3 , Figure 4 As shown, the outer contour of the limit block 611 is a trapezoid, the cylinder 46 is inserted into the arc groove 62, and the cylinder 46 and the arc groove 62 are slidably connected. One end of the spring 63 is connected to the cylinder 46, and the other end of the spring 63 is connected to the bottom of the arc groove 62. The size of the limit groove 64 is larger than the limit column 8.

[0037] Furthermore, when the rotating block 6 rotates, the cylinder 46 moves along the arc groove 62, and at the same time the spring 63 is deformed to generate elastic force. When the rotating block 6 is not subjected to external force, the spring 63 drives the rotating block 6 to rotate, so that part of the socket 61 is retracted into the opening 45. At this time, the distance between the limit block 611 and the opening 45 limits the hanging ring 51 to prevent it from falling off.

[0038] Combination Figure 3 , Figure 6 As shown, the lifting ring 51 is obliquely inserted into the socket 61, and the pump housing is suspended below the hook body 52. ​​The lever 7 is rotatably installed in the side cavity 43 through a pin shaft installed through it, and the end of the lever 7 is inserted into the through groove 81. The through groove 81 is transversely arranged on the limit column 8, and a spring 63 is installed on the top of the limit column 8, where the top of the spring 63 is connected to the through groove 81.

[0039] Furthermore, when disassembling or assembling, the lever 7 is pulled downward, and the end of the lever 7 abuts against the through slot 81 , so that the limiting column 8 moves upward along the rectangular cavity 42 , and the spring 63 deforms and compresses the limiting column 8 to disengage from the limiting slot 64 .

[0040] The working principle of the utility model is:

[0041] During installation, the hook body 52 hooks the pump housing, and installing a threaded rod in the threaded hole 53 can prevent it from falling off. Pull the lever 7 downward to make the lever 7 rotate counterclockwise based on the pin shaft. The end of the lever 7 abuts against the inner wall of the through groove 81, allowing the limit column 8 to move upward along the rectangular cavity 42. The limit column 8 and the limit groove 64 are separated. The spring 63 here is deformed and compressed to generate elastic force. After the lifting ring 51 is pressed against the limit block 611, appropriate force is released. The lifting ring 51 abuts against the limit block 611 to allow the rotating block 6 to rotate a certain angle along the inner wall of the inner cavity 44. The arc groove 62 moves along the cylinder 46, and the elastic force is released. The spring 63 is deformed and stretched, and when the socket 61 is completely exposed, the ring 51 can be smoothly inserted into the socket 61, and then the hook 5 is appropriately lifted up to remove the force from the rotating block 6. At this time, the rotating block 6 can rotate counterclockwise under the action of the spring 63, and the cylinder 46 again presses against the inner wall of the arc groove 62. At this time, part of the socket 61 is retracted into the opening 45 to form a misaligned relationship. The limiting column 8 falls into the limiting groove 64 under the action of the spring 63 to limit the rotating block 6. At this time, the distance between the limiting block 611 and the opening 45 becomes smaller, preventing the ring 51 from falling off from the socket 61.

[0042] When removing, pull the lever 7 downward to allow the limiting column 8 to move upward along the rectangular cavity 42, so that the limiting column 8 and the limiting groove 64 are disengaged, and the rotating block 6 rotates clockwise due to the action of gravity. At this time, the lifting ring 51 can be taken out normally.

[0043] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways without departing from the spirit of the present invention.

[0044] Although this article uses more terms such as 1. main body; 2. lifting equipment; 21. long board; 22. short board; 23. support rod; 3. gear; 31. sleeve; 32.
