Description

Technical Field

[0001] This utility model belongs to the technical field of insulator dipping equipment, and specifically relates to a dipping head assembly. Background Technology

[0002] Insulator dip coating is an advanced surface treatment process, mainly used to coat the surface of insulators with anti-flashover coatings to improve their insulation performance and pollution resistance.

[0003] In the existing insulator dip coating system, the insulator with a steel cap ball socket installed at the top is placed on the workpiece conveying station of the conveyor line. The workpiece conveying station moves the insulator along the conveyor line to the bottom of the dip coating machine head. Then, the dip coating machine head clamps the steel cap ball socket at the top of the insulator. Next, the workpiece conveying station reverses and resets. The dip coating tank moves on the conveyor line to the bottom of the dip coating machine head where the insulator has been attached. The dip coating machine head and the dip coating tank work together to coat the surface of the insulator with anti-flashover coating, completing the surface treatment process of the insulator.

[0004] Furthermore, existing dip coating machines typically perform surface coating on individual insulators. For example, prior art (publication number WO2016127508A1) discloses a device for coating porcelain or glass umbrella-type and bell-type insulators with RTV anti-flashover paint. This device includes a main frame, a machine head rotating frame, a geared frequency-modulated motor, and insulator quick-connect connectors. The machine head rotating frame is rotatably connected to the main frame via a corner shaft and bearing seats at both ends. A geared frequency-modulated motor is fixedly mounted on the rotating frame, and the output shaft of the motor is connected to the insulator quick-connect connectors. While this device performs surface coating on individual insulators during operation, it still suffers from low efficiency in practice and requires further improvement. Utility Model Content

[0005] The purpose of this invention is to provide a dip coating head assembly to solve the aforementioned problems existing in the prior art.

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

[0007] A dip coating head assembly includes a frame and at least two dip coating heads. The frame includes a head mounting beam and support columns at both ends of the head mounting beam. All dip coating heads are arranged sequentially along the length of the head mounting beam. Each dip coating head includes a ball head bolt for attaching a steel cap ball socket and a rotating shaft for rotating the ball head bolt. The ball head bolt is located below the head mounting beam, and the rotating shaft is rotatably connected to the head mounting beam. The lower end of the rotating shaft is connected to the ball head bolt. A clamping head located below the head mounting beam is sleeved on the rotating shaft. A cylinder is mounted on the head mounting beam, and the extension rod of the cylinder is rotatably connected to the clamping head to drive the clamping head downward and clamp the steel cap ball socket with the ball head bolt. A first drive motor is mounted at one end of the head mounting beam, and the first drive motor is connected to all the rotating shafts through a transmission mechanism.

[0008] As a preferred technical solution of this utility model, a cylinder is provided on both sides of each rotating shaft, the telescopic rods of the two cylinders are respectively connected to both ends of a connecting plate, and the clamping head is rotatably connected to the middle of the connecting plate.

[0009] As a preferred technical solution of this utility model, the upper end of the clamping head is provided with a first bearing sleeved on the outside of the rotating shaft, the inner ring of the first bearing is connected to the clamping head, and the outer ring of the first bearing is connected to the connecting plate.

[0010] As a preferred technical solution of this utility model, the transmission mechanism includes a transmission sprocket and a transmission chain. The motor shaft of the first drive motor and the upper part of each rotating shaft are equipped with transmission sprockets. The transmission sprockets on the motor shaft of the first drive motor are connected to the transmission sprockets on the upper part of the adjacent rotating shafts by transmission chains. The transmission sprockets on the upper parts of any two adjacent rotating shafts are connected by transmission chains.

[0011] As a preferred technical solution of this utility model, both ends of the machine head mounting beam are fixed with a flipping shaft. The two flipping shafts are rotatably connected to the upper ends of two support columns through bearing seats. A second drive motor for driving the flipping shafts to rotate is installed on one support column.

[0012] As a preferred technical solution of this utility model, an installation plate is fixed on another support column. The installation plate is located on the side of the bearing seat away from the machine head mounting beam. Multiple U-shaped photoelectric sensors are installed on the side of the installation plate close to the bearing seat, arranged in a ring in the vertical plane. A light-shielding plate that cooperates with the U-shaped photoelectric sensors is installed on the flip shaft.

[0013] As a preferred technical solution of this utility model, the mounting plate is equipped with multiple angle partition plates on the side near the bearing seat. All angle partition plates are arranged in a ring on the vertical plane. Each angle partition plate is equipped with a U-shaped photoelectric sensor at its upper end. The U-shaped grooves of all U-shaped photoelectric sensors are oriented towards the flip shaft, so that the light shield can pass through the U-shaped grooves of each U-shaped photoelectric sensor in sequence as the flip shaft rotates.

[0014] As a preferred technical solution of this utility model, the middle part of the rotating shaft is rotatably connected to the machine head mounting beam through a second bearing.

[0015] Beneficial effects: This utility model installs at least two dip coating heads arranged sequentially along the length of the head mounting beam on the frame. Each dip coating head is connected to the steel cap ball socket installed on the upper end of the insulator via a ball head bolt at its lower end. Then, the first drive motor can synchronously control the rotation of all rotating shafts through the transmission mechanism. The rotation of the rotating shafts drives the insulator to rotate in the dip coating tank, achieving comprehensive coating treatment on the surface of the insulator. In addition, a clamping head is also sleeved on the rotating shaft. The clamping head is rotatably connected to a cylinder installed on the upper end of the head mounting beam. In practice, the cylinder drives the clamping head to move downward, so that the clamping head and the ball head bolt can cooperate to clamp the steel cap ball socket, ensuring the stability of the steel cap ball socket during rotation. At the same time, it also ensures that no friction is generated between the steel cap ball socket and the clamping head during rotation, ensuring that this dip coating head assembly can simultaneously coat the surface of at least two insulators, improving coating efficiency.

Detailed Implementation

[0022] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0023] Example:

[0024] like Figures 1-5 As shown, this embodiment provides a dip coating head assembly, including a frame 1 and at least two dip coating heads. In practice, there can be more than two, such as... Figure 3Four dipping heads are provided. The frame 1 includes a head mounting beam 101 and support columns 102 supporting both ends of the head mounting beam 101. The two support columns 102 ensure the stability of the head mounting beam 101 and allow it to be suspended in the air for easy installation of the dipping heads. All the dipping heads are arranged sequentially along the length of the head mounting beam 101, ensuring that each head does not interfere with the others. Each dipping head includes a ball head bolt 2 for attaching a steel cap ball socket to the insulator, and a rotating shaft 3 for rotating the ball head bolt 2. The ball head bolt 2 is located below the head mounting beam 101, and the rotating shaft 3 is rotatably connected to the head mounting beam 101. The lower end of the rotating shaft 3 is connected to the ball head bolt 2. After the ball head bolt 2 attaches the insulator, the insulator is placed in the dipping coating tank. By rotating the rotating shaft 3, the insulator can rotate within the dipping coating tank, thus achieving the dipping of the steel cap ball socket. The entire surface of the insulator is coated. A clamping head 4, located below the machine head mounting beam 101, is fitted onto the rotating shaft 3, allowing the clamping head 4 to rotate and move up and down relative to the rotating shaft 3. A cylinder 5 is mounted on the machine head mounting beam 101, with its extension rod rotatably connected to the clamping head 4. The cylinder 5 drives the clamping head 4 downwards to engage with the ball head bolt 2, clamping the steel cap ball socket and ensuring its stability on the coating machine head. This allows the insulator to rotate stably in the coating tank when the coating machine head controls the rotation of the steel cap ball socket. Furthermore, because the extension rod of the cylinder 5 is rotatably connected to the clamping head 4, the clamping head 4 rotates along with the steel cap ball socket without causing friction. A first drive motor 6 is mounted at one end of the machine head mounting beam 101. The first drive motor 6 is connected to all rotating shafts 3 via a transmission mechanism, providing power for the rotation of the rotating shafts 3.

[0025] This invention features at least two dip coating heads arranged sequentially along the length of the head mounting beam 101 on a frame 1. Each dip coating head connects to a steel cap ball socket mounted on the upper end of the insulator via a ball head bolt 2 at its lower end. A first drive motor 6 synchronously controls the rotation of all rotating shafts 3 through a transmission mechanism. The rotation of the rotating shafts 3 drives the insulator to rotate within the dip coating tank, achieving comprehensive coating of the insulator surface. A clamping head 4 is also sleeved on the rotating shaft 3, and is rotatably connected to a cylinder 5 mounted on the upper end of the head mounting beam 101. In practice, the cylinder 5 drives the clamping head 4 downwards, allowing it to engage with the ball head bolt 2 to clamp the steel cap ball socket, ensuring its stability during rotation and preventing friction between the steel cap ball socket and the clamping head 4. This ensures that the dip coating head assembly can simultaneously coat at least two insulators, improving coating efficiency.

[0026] As a preferred embodiment of this invention, it should be further explained that a cylinder 5 is provided on each side of each rotating shaft 3, and the telescopic rods of the two cylinders 5 are respectively connected to the two ends of a connecting plate 7. Thus, the two cylinders 5 can control the stable up and down movement of the connecting plate 7. The clamping head 4 is rotatably connected to the middle of the connecting plate 7, so the two cylinders 5 can control the clamping head 4 to move up and down stably.

[0027] As a preferred embodiment of this invention, it should be further explained that the upper end of the clamping head 4 is provided with a first bearing 8 sleeved on the outside of the rotating shaft 3. The inner ring of the first bearing 8 is connected to the clamping head 4, and the outer ring of the first bearing 8 is connected to the connecting plate 7. This allows the clamping head 4 to move stably up and down with the connecting plate, and also allows the clamping head 4 to rotate freely relative to the connecting plate 7. In this way, when the steel cap ball socket rotates together with the insulator, the clamping head 4 can rotate together with the steel cap ball socket, ensuring that the insulator can be stably coated.

[0028] As a preferred embodiment of this invention, it should be further explained that the transmission mechanism includes a transmission sprocket 9 and a transmission chain 10. A transmission sprocket 9 is installed on the upper part of the motor shaft of the first drive motor 6 and each rotating shaft 3. One or two transmission sprockets 9 can be installed on the upper part of the rotating shaft 3 depending on the actual situation. For example, when one rotating shaft 3 needs to transmit power with two rotating shafts 3, two transmission sprockets 9 are installed on that rotating shaft 3. Similarly, when a rotating shaft 3 needs to transmit power with both the first drive motor 6 and another rotating shaft 3, two transmission sprockets 9 are also installed on that rotating shaft 3. Figure 1 and Figure 2 As shown, all rotating shafts 3 can rotate under the control of the first drive motor 6. The transmission sprocket 9 on the motor shaft of the first drive motor 6 is connected to the transmission sprocket 9 on the upper part of the adjacent rotating shaft 3 through the transmission chain 10. The transmission sprockets 9 on the upper part of any two adjacent rotating shafts 3 are connected through the transmission chain 10 to ensure the transmission effect.

[0029] As a preferred embodiment of this invention, it should be further explained that both ends of the machine head mounting beam 101 are fixed with a flipping shaft. The two flipping shafts are rotatably connected to the upper ends of the two support columns 102 through the bearing seat 11 to ensure the stability of the machine head mounting beam 101. A second drive motor 12 for driving the flipping shaft to rotate is installed on one support column 102. The machine head mounting beam 101 can be driven to rotate by the second drive motor 12, thereby controlling the insulator to tilt at a certain angle, which can better cooperate with the impregnation tank.

[0030] As a preferred embodiment of this example, it should be further explained that an mounting plate 13 is fixed on another support column 102. The mounting plate 13 is located on the side of the bearing seat 11 away from the machine head mounting beam 101. Multiple U-shaped photoelectric sensors 14 arranged in a ring in the vertical plane are mounted on the side of the mounting plate 13 near the bearing seat 11. A light-shielding plate 15 that cooperates with the U-shaped photoelectric sensor 14 is mounted on the flip shaft. As the machine head mounting beam 101 rotates, the light-shielding plate 15 will also rotate. When the light-shielding plate 15 cooperates with different U-shaped photoelectric sensors 14, the position of the light-shielding plate 15 can be determined by the U-shaped photoelectric sensors 14 at different positions, thereby determining the tilt angle of the machine head mounting beam 101. It is also convenient to actually shut down the second drive motor 12 by determining the tilt angle, ensuring that the insulator is properly set in the impregnation tank.

[0031] As a preferred embodiment of this invention, it should be further explained that multiple angle partition plates 16 are installed on the side of the mounting plate 13 near the bearing seat 11. All angle partition plates 16 are arranged in a ring in the vertical plane. Each angle partition plate 16 has a U-shaped photoelectric sensor 14 installed on its upper end, so that the U-shaped photoelectric sensors 14 are arranged in a certain angle. The U-shaped grooves of all U-shaped photoelectric sensors 14 are set towards the flip shaft, so that the light shield 15 can pass through the U-shaped groove of each U-shaped photoelectric sensor 14 in sequence as the flip shaft rotates. When the light shield 15 rotates into the U-shaped groove of a U-shaped photoelectric sensor 14, it blocks the signal of the U-shaped photoelectric sensor 14, so as to determine the tilt angle of the machine head mounting beam 101.

[0032] As a preferred embodiment of this invention, it should be further explained that the middle part of the rotating shaft 3 is rotatably connected to the machine head mounting beam 101 through a second bearing, ensuring the stability and flexibility of the rotating shaft 3.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
