Description

Technical Field

[0001] This utility model relates to the field of pump bracket manufacturing technology, specifically to pump bracket painting equipment. Background Technology

[0002] Pump brackets are key components in pump systems used to support the pump body, bearing assemblies, and ensure stable pump operation. They bear the loads generated by the pump body, impeller, and during operation, prevent the pump body from sinking or shifting due to gravity or vibration, fix the bearing assemblies, reduce vibration and wear during operation, and ensure the alignment accuracy of the pump shaft and motor shaft.

[0003] When performing rust prevention treatment on pump brackets, manual spraying with a handheld spray gun is required to paint the inside and outside of the pump brackets. Manual painting inside and outside is prone to uneven painting, missed spots, and low painting efficiency. Therefore, we propose a pump bracket painting equipment to solve this technical defect. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pump bracket painting device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pump bracket painting equipment, including a mounting bracket and a mounting base. The left and right ends of the bottom of the mounting base are provided with hydraulic push rods, and the push rods of the hydraulic push rods are provided with clamping seats. A hollow inner cylinder is rotatably inserted through the middle of the mounting base. A toothed disc is provided at the center of the upper end of the hollow inner cylinder. A drive assembly for driving the toothed disc to rotate is provided on the mounting base.

[0006] A movable outer cylinder is slidably connected to the outside of the hollow inner cylinder. The hollow inner cylinder is connected to the movable outer cylinder and rotates. A paint spray head is connected to the center of the lower end of the movable outer cylinder. An electric push rod is provided on the mounting base. The push rod of the electric push rod is connected to the movable outer cylinder. A fixed outer cylinder is provided at the upper end of the gear plate. The fixed outer cylinder is connected to the hollow inner cylinder. A movable inner cylinder is slidably connected inside the fixed outer cylinder. A locking element is provided on the fixed outer cylinder to lock and fix the movable inner cylinder.

[0007] The other end of the movable inner tube is equipped with an electric push rod 2. The push rod of the electric push rod 2 is equipped with a paint spray pipe. The paint spray pipe is connected to the movable inner tube through a connecting hose. The upper end of the fixed outer cylinder is rotatably connected to a connector. The connector is co-centered with the hollow inner cylinder. The mounting bracket is equipped with a paint supply component, which is connected to the connector.

[0008] Using the above technical solution, the pump bracket is inserted into the outside of the clamping seat by hand. The hydraulic push rod then moves the clamping seat to clamp the inner diameter of the pump bracket. After clamping and fixing the pump bracket, the moving inner tube is adjusted to move within the fixed outer tube according to the outer dimensions of the pump bracket, thus adjusting the movement of the paint spraying tube. The tube is positioned outside the pump bracket and locked in place by a locking mechanism. Simultaneously, paint is supplied by the paint supply assembly, causing paint to spray from the spray head and spraying tube. The drive assembly drives the gear plate, hollow inner cylinder, fixed outer tube, moving inner tube, electric push rod two, and spraying tube to rotate. This causes the spraying tube to rotate around the outside of the pump bracket for painting, while the spray head sprays paint inside the pump bracket. The electric push rod one pushes the spray head on the moving outer cylinder to move, and the electric push rod two pushes the spraying tube to move, achieving all-around painting treatment inside and outside the pump bracket.

[0009] As a preferred embodiment of this utility model, the clamping seat includes a vertical rod disposed at the hydraulic push rod and a clamping head disposed on the outside of the vertical rod.

[0010] As a preferred embodiment of this utility model, the drive assembly includes a drive motor disposed on the upper end of the mounting base, and the output end of the drive motor is provided with a transmission gear that meshes with the gear disc.

[0011] Using the above technical solution, the drive motor drives the transmission gear plate to rotate. By utilizing the meshing of the transmission gear plate with the gear plate, the transmission gear plate, the hollow inner cylinder, the fixed outer tube, the moving inner tube, the electric push rod II and the paint spraying tube are driven to rotate.

[0012] During rotation, the outer cylinder and the hollow inner cylinder rotate, and the electric push rod connects and limits the outer cylinder, ensuring that the outer cylinder does not rotate.

[0013] As a preferred embodiment of this utility model, both the movable outer cylinder and the fixed outer cylinder have sealing rings on their inner walls.

[0014] By adopting the above technical solution, the sealing ring ensures the sealing performance of the connection between the movable outer cylinder and the hollow inner cylinder, as well as the sealing performance of the connection between the fixed outer cylinder and the movable inner tube.

[0015] As a preferred embodiment of this utility model, the locking component includes a nut located at the upper end of the fixed outer tube, and the nut is internally threaded with a locking screw that passes through the fixed outer tube and contacts the surface of the movable inner tube.

[0016] By adopting the above technical solution, the moving inner tube can be locked and fixed by turning the locking screw on the nut into contact with the moving inner tube.

[0017] As a preferred technical solution of this utility model, the paint supply assembly includes a paint storage tank disposed inside the mounting bracket, a paint pump disposed outside the paint storage tank, an oil inlet pipe connected between the oil inlet of the paint pump and the paint storage tank, and an oil outlet pipe connected between the oil outlet of the paint pump and the connector.

[0018] Using the above technical solution, the paint pump draws paint out of the paint tank through the oil inlet pipe. By utilizing the interconnection between the paint pump, the drain pipe, the connector, the fixed outer cylinder, the movable inner cylinder, the connecting hose, the spray pipe, the hollow inner cylinder, the movable outer cylinder and the spray head, the paint liquid is sprayed out from the spray pipe and the spray head.

[0019] The rotation of the connector and the fixed outer cylinder ensures that the connector on the fixed outer cylinder will not rotate synchronously when the fixed outer cylinder rotates.

[0020] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0021] This pump bracket painting equipment involves inserting the pump bracket into the outside of a clamping seat by hand. A hydraulic pusher moves the clamping seat, clamping the inner diameter of the pump bracket. After clamping and fixing the pump bracket, the moving inner tube is adjusted within the fixed outer tube according to the outer dimensions of the pump bracket, allowing the paint spraying tube to move and adjust. Located outside the pump bracket, the paint spraying tube is locked in place by a locking mechanism. Simultaneously, paint is supplied by a paint supply assembly, causing paint to spray from the spray head and spraying tube. A drive assembly rotates the gear disc, hollow inner cylinder, fixed outer tube, moving inner tube, electric pusher two, and spraying tube, causing the spraying tube to rotate around the outside of the pump bracket for painting. The spray head sprays paint inside the pump bracket, and the electric pusher one moves the spray head on the moving outer cylinder, while the electric pusher two moves the spraying tube. Compared to existing technologies, this equipment achieves comprehensive painting of both the inside and outside of the pump bracket, ensuring uniform and efficient painting.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1 to 4 The pump bracket painting equipment in this embodiment mainly includes a mounting bracket 1, a mounting base 2, a hydraulic push rod 3, a clamping base 4, a hollow inner cylinder 5, a gear plate 6, a movable outer cylinder 7, a paint spray head 8, a drive assembly, a fixed outer cylinder 11, a movable inner tube 12, a locking component, an electric push rod 2 14, a paint spray pipe 15, a connector 16, an electric push rod 17, and a paint supply assembly. The components work together to achieve all-round painting treatment of the inside and outside of the pump bracket, ensuring the uniformity and efficiency of the painting.

[0029] Mounting bracket 1 serves as the supporting structure for the entire equipment. Mounting bracket 1 can be made of high-strength metal materials, such as stainless steel, to ensure its structural stability and load-bearing capacity, and to withstand various forces generated during equipment operation.

[0030] The mounting bracket 1 has four mounting holes, through which fastening bolts are passed for hanging and hoisting.

[0031] Hydraulic push rods 3 are fixed on the left and right end surfaces at the bottom of the mounting base 2. The hydraulic push rods 3 are installed horizontally and vertically. Each hydraulic push rod 3 has a clamping seat 4 at its push rod position. The clamping seat 4 includes a vertical rod fixed to the push rod position of the hydraulic push rod 3 and a clamping head fixed to the outside of the vertical rod. The vertical rod is fixed to the push rod of the hydraulic push rod 3 by threaded connection or welding. The clamping head can be made of rubber, which has a certain degree of flexibility and friction, so as to ensure reliable clamping of the inner diameter of the pump bracket and avoid damage to the pump bracket.

[0032] A hollow inner cylinder 5 is rotatably inserted through the middle of the mounting base 2. The hollow inner cylinder 5 is connected to the mounting base 2 through a bearing, enabling it to rotate freely within the mounting base 2. A geared disc 6 is fixed at the center of the upper end of the hollow inner cylinder 5. The geared disc 6 is fixed to the hollow inner cylinder 5 by key connection or welding to ensure that the two rotate synchronously.

[0033] The hollow inner cylinder 5 is slidably connected to the outer side of a movable outer cylinder 7. The hollow inner cylinder 5 and the movable outer cylinder 7 are sealed together by a sealing ring to prevent paint leakage. The hollow inner cylinder 5 is connected to the movable outer cylinder 7 and rotates. The movable outer cylinder 7 can slide up and down along the hollow inner cylinder 5. The lower end of the movable outer cylinder 7 is connected to a paint spray head 8 with a central connection. The paint spray head 8 has multiple paint spray holes for spraying paint into the pump bracket. An electric push rod 17 is fixed on the upper surface of the mounting base 2. The push rod of the electric push rod 17 is connected and fixed to the movable outer cylinder 7. By the extension and retraction of the electric push rod 17, the movable outer cylinder 7 can be pushed up and down on the hollow inner cylinder 5, thereby adjusting the position of the paint spray head 8.

[0034] The mounting base 2 is equipped with a drive assembly for driving the gear disk 6 to rotate. The drive assembly includes a drive motor 9 located on the upper surface of the mounting base 2. The drive motor 9 is fixed to the mounting base 2 by bolts. The output end of the drive motor 9 is fixed with a transmission gear disk 10 that meshes with the gear disk 6. The transmission gear disk 10 and the output shaft of the drive motor 9 are connected and fixed by a key. When the drive motor 9 is working, it drives the transmission gear disk 10 to rotate. Since the transmission gear disk 10 meshes with the gear disk 6, it drives the gear disk 6 and the hollow inner cylinder 5 to rotate.

[0035] The upper end of the gear disc 6 is fixed with a fixed outer cylinder 11, which is connected to the hollow inner cylinder 5. Paint can enter the fixed outer cylinder 11 through the hollow inner cylinder 5. A movable inner cylinder 12 is slidably connected inside the fixed outer cylinder 11. The fixed outer cylinder 11 and the movable inner cylinder 12 are also sealed together by a sealing ring. The movable inner cylinder 12 can slide left and right inside the fixed outer cylinder 11 to adapt to pump brackets of different sizes.

[0036] The fixed outer tube 11 is provided with a locking component for locking and fixing the movable inner tube 12. The locking component includes a nut fixed to the upper surface of the fixed outer tube 11. The nut is internally threaded with a locking screw 13 that passes through the fixed outer tube 11 and contacts the surface of the movable inner tube 12. When the movable inner tube 12 is adjusted to a suitable position, the locking screw 13 is rotated to make it tightly contact the surface of the movable inner tube 12, thereby locking and fixing the movable inner tube 12.

[0037] The other end of the movable inner tube 12 is provided with an electric push rod 14. The electric push rod 14 is fixed to the movable inner tube 12 by bolts. A paint spraying pipe 15 is fixed at the push rod of the electric push rod 14. Multiple nozzle pipes are connected to the outside of the paint spraying pipe 15 facing the clamping seat 4. The paint spraying pipe 15 is connected to the movable inner tube 12 through a connecting hose. Paint can enter the paint spraying pipe 15 through the movable inner tube 12 and the connecting hose, and be sprayed out from the nozzle pipes on the paint spraying pipe 15 to paint the outside of the pump bracket.

[0038] The upper end of the fixed outer cylinder 11 is rotatably connected to a connector 16. The connector 16 is co-centered with the hollow inner cylinder 5. The connector 16 and the fixed outer cylinder 11 are connected by a bearing to ensure that the connector 16 will not rotate synchronously when the fixed outer cylinder 11 rotates.

[0039] The mounting bracket 1 is equipped with a paint supply assembly, which includes a paint storage tank 18 fixed inside the mounting bracket 1. The paint storage tank 18 is used to store paint and can be made of plastic or metal. A paint pump 19 is provided on the outside of the paint storage tank 18. The paint pump 19 is fixed to the mounting bracket 1 by bolts. An oil inlet pipe 20 is connected between the oil inlet of the paint pump 19 and the paint storage tank 18. An oil outlet pipe 21 is connected between the oil outlet of the paint pump 19 and the connector 16. When the paint pump 19 is working, the paint in the paint storage tank 18 is drawn out through the oil inlet pipe 20 and then transported to the connector 16 through the oil outlet pipe 21, and then enters the entire painting system.

[0040] Structural design principles and usage steps

[0041] Pump bracket clamping: The operator holds the pump bracket and inserts the pump bracket into the outside of the clamping seat 4. Then, the hydraulic push rod 3 is activated. The push rod of the hydraulic push rod 3 extends and pushes the clamping seat 4 to move into the inner diameter of the pump bracket, thereby clamping the inner diameter of the pump bracket and fixing the pump bracket on the equipment.

[0042] Adjusting the position of the paint spray pipe 15: Based on the outer dimensions of the pump bracket, adjust the position of the movable inner pipe 12 inside the fixed outer pipe 11 so that the paint spray pipe 15 is located at a suitable position outside the pump bracket. After adjustment, turn the locking screw 13 to lock and fix the movable inner pipe 12.

[0043] Paint supply system startup: Start the paint pump 19. The paint pump 19 draws the paint out of the paint tank 18 through the oil inlet pipe 20, and delivers it to the connector 16 through the oil discharge hard pipe 21. Then, it enters the fixed outer cylinder 11, the movable inner pipe 12, the connecting hose, the spray pipe 15, the hollow inner cylinder 5, and the movable outer cylinder 7 in sequence, and is finally sprayed out from the spray head 8 and the spray pipe 15.

[0044] Spray painting operation: Start the drive motor 9, which drives the transmission gear plate 10 to rotate. The transmission gear plate 10 meshes with the gear plate 6, thereby driving the gear plate 6, hollow inner cylinder 5, fixed outer tube 11, movable inner tube 12, electric push rod 14 and spray pipe 15 to rotate, so that the spray pipe 15 rotates around the outside of the pump bracket to spray paint. At the same time, start the electric push rod 17, which pushes the spray head 8 on the movable outer cylinder 7 to move up and down, so as to achieve all-round spray painting treatment inside and outside the pump bracket.

[0045] Painting complete: After the painting operation is completed, turn off the drive motor 9, electric push rod 17, electric push rod 2 14 and paint pump 19, and the operator removes the painted pump bracket from the clamping seat 4.

[0046] To achieve automated control of the equipment, a control system can be installed, which includes a controller and an operation panel. The controller can be a microcontroller or a programmable logic controller (PLC). The operation panel is equipped with various control buttons and a display screen for operators to input control commands and view the equipment's operating status.

[0047] Through the above specific implementation methods, this pump bracket painting equipment can achieve all-round painting treatment of the inside and outside of the pump bracket, with the advantages of uniform painting and high efficiency. At the same time, through system control and structural material optimization, the automation level and reliability of the equipment are improved.

[0048] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
