Description

Technical Field

[0001] This utility model relates to the field of PC pipe processing and production technology, and in particular to a PC pipe surface spraying device. Background Technology

[0002] After PC pipes are manufactured, they need to undergo surface pretreatment to remove surface impurities, mask areas that do not require coating, and finally evenly spray the prepared coating material onto the pipe surface. However, existing equipment for coating PC pipes has the following problems during use:

[0003] 1. Due to the fact that most existing spraying devices require the pipe to be horizontally fixed on the rotating shaft in order to spray the spray material evenly on the pipe surface, it is necessary to apply support force to both ends of the pipe to ensure that the pipe remains coaxial with the rotating shaft. Therefore, the pipe installation is complicated.

[0004] 2. Existing spraying devices use a fixed spray head, and the control tube moves along the length direction, passing under the spray head to spray the tube surface. This results in the existing spraying devices often being designed to be too long, occupying too much space and restricting the user's placement. Utility Model Content

[0005] In order to solve the above problems, the purpose of this utility model is to provide a PC pipe surface spraying device, which solves the problem of the cumbersome process of installing PC pipes in the spraying device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A PC pipe surface spraying device includes a housing with its opening facing right, four support columns fixed to the four corners of the lower side of the housing, a rotating shaft fixed between the inner walls of the front and rear sides of the housing, a vertical rotating plate located between the inner walls of the front and rear sides of the housing and rotatably connected to the rotating shaft, a horizontal base plate fixed to the lower end of the vertical rotating plate and extending into the housing, a rotating column rotatably located above the horizontal base plate and along the vertical height direction of the housing, an installation assembly located at the upper end of the rotating column for coaxially fixing the pipe to the rotating column, a spraying assembly located on the left side of the housing for spraying material onto the surface of the pipe inside the housing, and a locking assembly located on the right side of the housing for keeping the rotating plate in a vertical state.

[0008] The installation assembly includes a limiting groove located above the rotating column and extending through the side wall of the rotating column in the front-back direction; a control sleeve movably sleeved on the upper end of the rotating column; a drive sleeve threadedly connected to the control sleeve; a pair of rotating seats respectively corresponding to the openings at the front and rear ends of the limiting groove and fixedly connected to the lower end of the control sleeve; two fixed shafts fixedly installed in the corresponding rotating seats, corresponding one-to-one with each rotating seat; two support members movably installed in the corresponding rotating seats, corresponding one-to-one with each support member; two movable tracks corresponding one-to-one with each support member and installed on the corresponding support members along the length direction of the support members; a connecting shaft located inside the drive sleeve and inside the limiting groove and rotatably connected to the upper ends of the two side support members; and a movable plate fixedly installed on the inner wall of the drive sleeve and inside the limiting groove and fixedly connected to both ends of the connecting shaft.

[0009] Each of the aforementioned fixed shafts is movably disposed within a corresponding side movable track;

[0010] The lower middle section of the housing is provided with a clearance groove, and a drive motor extending from the clearance groove and located below the housing is fixedly mounted on the lower side of the horizontal base plate. The output shaft of the drive motor is axially fixedly connected to the rotating column.

[0011] More preferably, the spraying assembly includes a limiting rail disposed on the left side of the housing along the vertical height direction, a sliding member slidably disposed within the limiting rail, an electric spray head fixed on the sliding member with its output end horizontally extending into the housing, a paint box fixed on the outer wall of the left side of the housing, a material delivery pipe fixed on the paint box and used to connect the inside of the paint box with the input end of the electric spray head, and a control sub-assembly disposed on the housing and used to drive the electric spray head to slide up and down.

[0012] More preferably, the control sub-assembly includes a threaded sleeve fixed to the left side of the sliding member and located on the outside of the housing, a height adjusting screw rotatably mounted on the left outer wall of the housing and threadedly connected to the inner wall of the threaded sleeve, and a rotating motor fixed to the housing with its output shaft axially fixedly connected to the height adjusting screw.

[0013] More preferably, the locking assembly includes a hinge seat fixed to the upper part of the front outer wall of the housing, a baffle plate disposed on the upper part of the front side of the housing and rotatably connected to the hinge seat, a support member fixed to the rear outer wall of the housing, and a hook member fixed to the right side of the baffle plate.

[0014] More preferably, a horizontal support plate is fixedly provided on the lower right side of the housing.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model involves rotating a vertical rotating plate to a horizontal position, placing a PC tube on the rotating column, and fitting the mounting assembly onto the upper end of the rotating column. By rotating the control sleeve, the two side supports are pushed away from the central axis of the rotating column, pushing the inner wall of the PC tube away from the control sleeve. Pressure is applied to the control sleeve to make the end of the PC tube away from the control sleeve abut against the support plate. Then, the vertical rotating plate is rotated to a vertical position. At this time, under the action of the PC tube's own weight, the lower end of the PC tube is in horizontal contact with the support plate, and the upper end is supported by the mounting assembly. This keeps the PC tube in a vertical position and, due to the limiting effect of the mounting assembly, keeps it coaxial with the rotating column. Therefore, this product only requires operation on one end of the PC tube to achieve the effect of coaxially installing the PC tube on the rotating column, achieving the purpose of rapid installation.

[0017] 2. This utility model uses a control sub-component to drive an electric spray head to reciprocate up and down at a uniform speed, and sprays paint horizontally and evenly during the movement. The PC tube rotates circumferentially at a uniform speed under the drive motor, thereby achieving uniform spraying of paint onto the surface of the PC tube. During the rotation of the PC tube, the centrifugal force further ensures that the spray material evenly covers the surface of the tube. Attached Figure Description

Detailed Implementation

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, a PC pipe surface spraying device according to this embodiment includes a housing 1 with its opening facing the right, four support columns 2 respectively fixed on the four corners of the lower side of the housing 1, a rotating shaft 3 fixed between the inner walls of the front and rear sides of the housing 1, a vertical rotating plate 4 disposed between the inner walls of the front and rear sides of the housing 1 and rotatably connected to the rotating shaft 3, a horizontal base plate 5 fixed at the lower end of the vertical rotating plate 4 and extending into the housing 1, a rotating column 6 rotatably disposed above the horizontal base plate 5 and disposed along the vertical height direction of the housing 1, an installation assembly 7 disposed at the upper end of the rotating column 6 and used to fix the pipe and the rotating column 6 coaxially to the rotating column 6, a spraying assembly 8 disposed on the left side of the housing 1 and used to spray material onto the surface of the pipe inside the housing 1, and a locking assembly 9 disposed on the right side of the housing 1 and used to keep the rotating plate in a vertical state.

[0028] The mounting assembly 7 includes a limiting groove 71 located above the rotating column 6 and extending through the side wall of the rotating column 6 in the front-back direction; a control sleeve 72 movably sleeved on the upper end of the rotating column 6; a drive sleeve 73 threadedly connected to the control sleeve 72; a pair of rotating seats 74 corresponding to the openings at the front and rear ends of the limiting groove 71 and fixedly connected to the lower end of the control sleeve 72; two fixed shafts 75 fixedly fixed in the corresponding rotating seats 74, corresponding to each of the rotating seats 74; two support members 76 movably installed in the corresponding rotating seats 74, corresponding to each of the rotating seats 74; two movable tracks 77 corresponding to each of the support members 76 and installed on the corresponding support members 76 along the length of the support members 76; a connecting shaft 78 located inside the drive sleeve 73 and inside the limiting groove 71 and rotatably connected to the upper ends of the two side support members 76; and a movable plate 79 fixedly installed on the inner wall of the drive sleeve 73 and inside the limiting groove 71 and fixedly connected to both ends of the connecting shaft 78.

[0029] Each fixed shaft 75 is movably mounted within the corresponding movable track 77 on the side.

[0030] A clearance groove 10 is provided in the middle section of the lower side of the housing 1. A drive motor 11 extending from the clearance groove 10 and located below the housing 1 is fixedly provided on the lower side of the horizontal base plate 5. The output shaft of the drive motor 11 is axially fixedly connected to the rotating column 6.

[0031] When using this product, the vertical rotating plate 4 rotates downwards to a horizontal position. Then, the operator places the PC tube to be sprayed onto the rotating column 6 and pushes it to the left until the left end of the PC tube abuts against the support plate 13. Next, the control sleeve 73 is inserted into the right end of the PC tube, and the moving plate 79 is inserted into the corresponding limiting groove 71. This restricts the movement of the moving plate 79 by the side walls of the limiting groove 72, thus limiting the rotation of the drive sleeve 73. At this time, rotating the control sleeve 72 drives the drive sleeve 73 along the threaded connection with the control sleeve 72. The moving plate 79 moves downwards, causing the two side supports 76 to rotate and extend synchronously away from the central axis of the rotating column 6 until the lower ends of the two side supports 76 abut against the inner wall of the PC tube. At this time, the PC tube moves to the coaxial position with the rotating column 6 under the influence of the supports 76. At this time, the operator presses the control sleeve 72 to keep the PC tube in contact with the support plate 12, while continuously rotating the vertical rotating plate 4 upwards, so that the PC tube falls towards the support plate 13 under its own weight, thereby preventing the PC tube from tilting.

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the spraying assembly 8 includes a limiting rail 81 disposed on the left side of the housing 1 along the vertical height direction, a sliding member 82 slidably disposed within the limiting rail 81, an electric spraying head 83 fixed on the sliding member 82 with its output end horizontally extending into the housing 1, a paint box 84 fixed on the outer wall of the left side of the housing 1, a material delivery pipe 85 fixed on the paint box 84 and used to connect the inside of the paint box 84 with the input end of the electric spraying head 83, and a control sub-assembly 86 disposed on the housing 1 and used to drive the electric spraying head 83 to slide up and down.

[0033] The control sub-assembly 86 includes a threaded sleeve 861 fixed to the left side of the sliding member 82 and located on the outside of the housing 1, a height adjusting screw 862 rotatably mounted on the left outer wall of the housing 1 and threadedly connected to the inner wall of the threaded sleeve 861 along the vertical height direction of the housing 1, and a rotary motor 863 fixed to the housing 1 and whose output shaft is axially fixedly connected to the height adjusting screw 862.

[0034] When using this product, the rotating motor 863 is started, which drives the height adjusting screw 862 to rotate. This causes the threaded sleeve 861, which is threaded to it, to move upward along the thread direction. This causes the sliding part 82 to move upward synchronously. After moving upward to the upper end of the limit track 81, the rotating motor 863 reverses, causing the sliding part 82 to move downward. This causes the electric spray head 83 to move up and down reciprocally, spraying the surface of the PC pipe. The spray material in the paint box 84 is sprayed onto the surface of the PC pipe by the electric spray head 83 through the feed pipe 85, achieving the effect of uniformly spraying the PC pipe.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, the locking assembly 9 includes a hinge seat 91 fixed to the upper part of the front outer wall of the housing 1, a baffle 92 provided on the upper part of the front side of the housing 1 and rotatably connected to the hinge seat 91, a support member 93 fixed to the rear outer wall of the housing 1, and a hook member 94 fixed to the right side of the baffle 92.

[0036] When this product is in use, there is a gap between the upper end of the vertical rotating plate 4 and the upper end of the casing 1 when the vertical rotating plate 4 is placed vertically. A longer auxiliary rod is used to push the hook 93 upward, causing the baffle 92 to rotate upward until it is no longer blocking the vertical rotating plate 4. Then, the auxiliary rod is used to hook the upper end of the vertical rotating plate 4 and pull it forward, causing the vertical rotating plate 4 to rotate downward to a horizontal state. After rotating to a vertical state, the baffle 92 is rotated by the auxiliary rod to block the upper end of the vertical rotating plate 4 and to fit against the surface of the vertical rotating plate 4, preventing the vertical rotating plate 4 from rotating to the right.

[0037] like Figure 1 and Figure 2 As shown, a horizontal support plate 12 is fixedly installed on the lower right side of the housing 1.

[0038] When this product is in use, the horizontal support plate 12 restricts the vertical rotating plate 4 from rotating downwards, preventing it from rotating excessively and causing the sprayed PC tube to slip off.

[0039] The working principle of this device is as follows:

[0040] Step 1: Use the longer auxiliary rod to push the hook 93 upwards, causing the baffle 92 to rotate upwards until it is no longer blocking the vertical rotating plate 4. Then, use the auxiliary rod to hook into the upper end of the vertical rotating plate 4 and pull it forward, causing the vertical rotating plate 4 to rotate downwards to a horizontal state. Then, the operator puts the PC tube to be sprayed onto the rotating column 6 and pushes it to the left until the left end of the PC tube abuts against and adheres to the support plate 13.

[0041] Step 2: Then, insert the control sleeve 73 into the right end of the PC tube, and insert the moving plate 79 into the limiting groove 71 accordingly. This restricts the rotation of the drive sleeve 73 by limiting the side walls of the limiting groove 72. At this time, rotating the control sleeve 72 causes the drive sleeve 73 to move downward along the threaded connection direction with the control sleeve 72, thereby causing the moving plate 79 to move downward continuously. This causes the two side support members 76 to rotate and extend synchronously from the center axis of the rotating column 6 to both sides until the lower ends of the two side support members 76 abut against the inner wall of the PC tube. At this time, the PC tube moves to the coaxial position with the rotating column 6 under the influence of the support members 76. At this time, the operator presses the control sleeve 72 to keep the PC tube in contact with the support plate 12, while continuously rotating the vertical rotating plate 4 upward, so that the PC tube falls towards the support plate 13 under its own weight, thereby preventing the PC tube from tilting.

[0042] Step 3: After rotating to the vertical position, the baffle 92 is rotated to block the upper end of the vertical rotating plate 4 by the auxiliary rod and to fit against the surface of the vertical rotating plate 4 to prevent the vertical rotating plate 4 from rotating to the right. Then, the drive motor 11 is started to drive the rotating column 6 to rotate, which causes the PC tube placed on the support plate 13 of the rotating column 6 to rotate synchronously. Then, the rotation motor 863 is started to drive the height adjustment screw 862 to rotate, so that the threaded sleeve 861 connected to it moves upward with the thread direction, thereby driving the sliding part 82 to move upward synchronously. After moving upward to the upper end of the limit track 81, the rotation motor 863 reverses, driving the sliding part 82 to move downward, thereby causing the electric spray head 83 to move up and down reciprocally to spray the surface of the PC tube. The spray material in the paint box 84 is sprayed onto the surface of the PC tube by the electric spray head 83 through the material conveying pipe 85, so as to achieve the effect of uniformly spraying the PC tube.
