Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the field of steel pipe processing equipment technology, and more specifically, to a steel pipe rotary spraying device. Background Technology
[0002] Steel pipes are not only used for transporting fluids and powdery solids, exchanging heat energy, and manufacturing mechanical parts and containers, but they are also an economical steel material. Using steel pipes to build highway bridges can not only save steel and simplify construction, but also greatly reduce the area to be coated with protective layer, saving investment and maintenance costs.
[0003] Currently, operators frequently use spraying equipment when processing steel pipes. While existing spraying equipment has basic rotary spraying capabilities, it lacks corresponding drying equipment. This means that after spraying, the paint on the steel pipe surface must be allowed to air dry naturally before it can be removed and stored. The long drying time reduces operator efficiency and causes inconvenience. Therefore, improvements are needed. Utility Model Content

[0009] As a preferred technical solution of this utility model, a movable plate is movably connected to the left side of the top of the base, and a movable block is fixedly connected to the bottom of the movable plate. The bottom of the movable block passes through the base and extends into the interior of the base, and its outer surface is movably connected to the interior of the base.
[0010] As a preferred embodiment of this utility model, a protective cover is fixedly connected to the top of the movable plate, and a second motor is fixedly installed inside the protective cover.
[0011] As a preferred embodiment of this utility model, the other end of the output shaft of the second motor is fixedly sleeved with a rotating shaft, and the right end of the rotating shaft passes through the protective cover and extends to the outside of the right end of the protective cover and is fixedly connected to a second frustum pressure block.
[0012] As a preferred technical solution of this utility model, a long block is fixedly connected to the right side of the top of the base, a round block is movably installed inside the long block, a motion shaft is fixedly connected to the left end of the round block, and the left end of the motion shaft passes through the long block and extends to the outside of the left end of the long block and is fixedly connected to a first truncated cone pressure block.
[0013] As a preferred embodiment of this utility model, a spring is fixedly connected to the left end of the movable block, and the left end of the spring is fixedly connected to the left side of the inner surface of the base.
[0014] As a preferred embodiment of this utility model, a third motor is fixedly installed at the top of the inner surface of the base, and a round shaft is fixedly sleeved at the other end of the output shaft of the third motor, and a convex block is fixedly sleeved on the outer surface of the round shaft.
[0015] The beneficial effects of the embodiments disclosed herein are as follows:
[0016] 1. In this disclosure, by setting up a first motor, a rotating shaft, a hollow block, and a connecting shaft, when the operator starts the first motor, the rotating shaft and the hollow block will rotate, thereby causing the inner surface of the hollow block to press and push the outer surface of the connecting shaft, which in turn causes the connecting shaft to drive the moving plate and the hot air fan to move left and right as a whole. This allows the air outlet to evenly dry the outer surface of the steel pipe, thereby accelerating the drying speed of the paint on the outer surface of the steel pipe, reducing the operator's working time, and bringing convenience to the operator.
[0017] 2. In this disclosure, by setting up a movable block, a spring, a third motor, a round shaft, and a convex block, the operator starts the third motor, which will cause the round shaft and the convex block to rotate. This causes the outer surface of the convex block to press and push the outer surface of the movable block, thereby causing the movable block to drive the entire movable plate to move to the left. At this time, the spring will be in a compressed state. Then, the operator can place a steel pipe of the corresponding length between the second truncated cone pressure block and the first truncated cone pressure block. Subsequently, the operator controls the third motor to restore the round shaft and the convex block to their initial state. Due to the restoring effect of the spring force, the movable block will drive the entire movable plate to move to the right, thereby enabling the second truncated cone pressure block to fix and rotate steel pipes of different lengths.

[0025] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.
[0026] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."
[0027] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.
[0028] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them.

[0029] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0031] like Figures 1-5 As shown, a steel pipe rotary spraying device according to an embodiment of the present disclosure is illustrated, including a base 1, an mounting plate 2 fixedly installed at the rear of the top of the base 1, a rectangular plate 12 fixedly connected to the top of the mounting plate 2, a hot air blower 3 fixedly installed at the bottom left side of the mounting plate 2, an air outlet 4 fixedly connected to the right side of the hot air blower 3, the right end of the air outlet 4 passing through the mounting plate 2 and extending to the right side of the outer surface of the mounting plate 2, an air inlet 5 fixedly installed on the left side of the hot air blower 3, a limiting block 6 fixedly sleeved on the outer surface of the air outlet 4, the outer surface of the limiting block 6 being movably connected to the interior of the mounting plate 2, a movable plate 7 fixedly connected to the top of the hot air blower 3, a first motor 8 fixedly installed at the top of the rectangular plate 12, a rotating shaft 9 fixedly sleeved at the other end of the output shaft of the first motor 8, a hollow block 10 fixedly sleeved on the outer surface of the rotating shaft 9, a connecting shaft 11 movably installed inside the hollow block 10, and the right side of the connecting shaft 11 being fixedly connected to the left side of the movable plate 7.
[0032] When the operator starts the first motor 8, the rotating shaft 9 and the hollow block 10 will rotate, causing the inner surface of the hollow block 10 to press and push the outer surface of the connecting shaft 11. This causes the connecting shaft 11 to drive the moving plate 7 and the hot air blower 3 to move left and right as a whole, so that the air outlet 4 can dry the outer surface of the steel pipe, thus avoiding the need for the paint to dry for a long time after spraying.
[0033] In some examples, a slider 13 is movably mounted inside the rectangular plate 12, and a second pneumatic cylinder 15 is fixedly mounted at the bottom end of the slider 13.
[0034] Since both the outer surface of the slider 13 and the inner surface of the rectangular plate 12 are smooth, the movement of the slider 13 inside the rectangular plate 12 is smoother.
[0035] In some examples, a first pneumatic cylinder 14 is fixedly installed on the left end of the rectangular plate 12, and the right end of the first pneumatic cylinder 14 passes through the rectangular plate 12 and extends to the left side of the slider 13 and is fixedly connected to the left side of the slider 13.
[0036] When the operator starts the first pneumatic cylinder 14, the slider 13 will move left and right.
[0037] In some examples, a rectangular block 16 is fixedly connected to the bottom of the second pneumatic cylinder 15, an installation port 17 is fixedly connected to the right end of the rectangular block 16, and a mist nozzle 18 is fixedly installed at the bottom of the rectangular block 16.
[0038] The design of the mounting port 17 allows the operator to connect the paint hose to the mounting port 17, thereby enabling the paint to be sprayed out from the mist nozzle 18.
[0039] In some examples, a movable plate 19 is movably connected to the left side of the top of the base 1, and a movable block 27 is fixedly connected to the bottom of the movable plate 19. The bottom of the movable block 27 passes through the base 1 and extends into the interior of the base 1, and its outer surface is movably connected to the interior of the base 1.
[0040] Due to the design of the movable block 27, the movement of the movable plate 19 is effectively limited.
[0041] In some examples, a protective cover 20 is fixedly connected to the top of the movable plate 19, and a second motor 21 is fixedly installed inside the protective cover 20.
[0042] Due to the design of the protective cover 20, the second motor 21 can be well protected.
[0043] In some examples, the other end of the output shaft of the second motor 21 is fixedly sleeved with a rotating shaft 22, and the right end of the rotating shaft 22 passes through the protective cover 20 and extends to the outside of the right end of the protective cover 20 and is fixedly connected to the second frustum pressure block 32.
[0044] When the operator starts the second motor 21, the rotating shaft 22 and the second cone-shaped pressure block 32 will rotate.
[0045] In some examples, a long block 23 is fixedly connected to the right side of the top of the base 1, a circular block 24 is movably installed inside the long block 23, a motion shaft 25 is fixedly connected to the left end of the circular block 24, the left end of the motion shaft 25 passes through the long block 23 and extends to the outside of the left end of the long block 23 and is fixedly connected to a first frustum pressure block 26.
[0046] When the second cone-shaped pressure block 32 drives the steel pipe to rotate, the steel pipe will cause the first cone-shaped pressure block 26, the motion shaft 25 and the circular block 24 to rotate together.
[0047] In some examples, the left end of the movable block 27 is fixedly connected to a spring 28, and the left end of the spring 28 is fixedly connected to the left side of the inner surface of the base 1.
[0048] Due to the design of spring 28, it can effectively reset the movement of the movable block 27 and the movable plate 19 as a whole.
[0049] In some examples, a third motor 29 is fixedly installed at the top of the inner surface of the base 1, and a round shaft 30 is fixedly sleeved at the other end of the output shaft of the third motor 29. A convex block 31 is fixedly sleeved on the outer surface of the round shaft 30.
[0050] When the operator starts the third motor 29, the round shaft 30 and the convex block 31 will rotate, which will cause the outer surface of the convex block 31 to press and push the outer surface of the movable block 27, thereby causing the movable block 27 to move to the left.
[0051] Working principle and usage process of this utility model:
[0052] First, the operator starts the third motor 29 according to the length of the steel pipe, causing the round shaft 30 and the convex block 31 to rotate. This causes the outer surface of the convex block 31 to press and push the outer surface of the movable block 27, which in turn causes the movable block 27 to move the movable plate 19 to the left. At this time, the spring 28 is compressed, which increases the distance between the second truncated cone pressure block 32 and the first truncated cone pressure block 26. Then, the operator inserts the right end of the steel pipe of the corresponding length into the outer surface of the first truncated cone pressure block 26. Subsequently, the operator starts the third motor 29 again, causing the round shaft 30 and the convex block 31 to return to their initial state. Due to the restoring effect of the spring 28, the movable block 27 moves the movable plate 19 to the right. The movement causes the outer surface of the second truncated cone block 32 to insert into the interior of the left end of the steel pipe, thus achieving a fixing effect. Then, the operator starts the second motor 21, causing the rotating shaft 22 to drive the second truncated cone block 32 and the steel pipe to rotate. The steel pipe will then drive the first truncated cone block 26, the moving shaft 25, and the circular block 24 to rotate together. At this time, the operator connects the paint spraying hose to the installation port 17. Subsequently, the paint will pass through the rectangular block 16 and be sprayed from the bottom of the mist nozzle 18 onto the outer surface of the steel pipe. Then, the operator operates the first pneumatic cylinder 14, causing the slider 13 to drive the second pneumatic cylinder 15 to move left and right, thereby enabling the mist nozzle 18 to spray the outer surface of the steel pipe evenly.
[0053] Finally, when the spraying operation is completed, the operator runs the hot air blower 3 and the first motor 8. The operation of the hot air blower 3 causes the air inlet 5 to draw in outside air, and then converts the cold air into hot air and blows it out from the air outlet 4. The operation of the first motor 8 causes the rotating shaft 9 and the hollow block 10 to rotate, so that the inner surface of the hollow block 10 squeezes and pushes the outer surface of the connecting shaft 11, which in turn causes the connecting shaft 11 to drive the moving plate 7 and the air outlet 4 to move left and right as a whole. This allows the air outlet 4 to dry the outer surface of the steel pipe, thus saving the operator's working time and bringing convenience to the operator.
[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
