Description

TECHNICAL FIELD

[0001] The application relates to the field of chain ring welding of anchor chains, and particularly relates to a chain ring welding device for ship anchor chain processing. BACKGROUND

[0002] In the field of shipbuilding and ocean engineering, an anchor chain serves as a key component connecting an anchor and a ship body and bears the important function of transmitting and buffering external forces on the ship. The strength and reliability of the anchor chain are directly related to the safety and stability of the ship. The anchor chain is usually connected by a plurality of chain rings through welding or other connecting methods, and therefore, the welding quality of the chain rings is a key factor affecting the overall performance of the anchor chain. The chain ring welding of the ship anchor chain mainly relies on traditional welding methods such as manual arc welding and submerged arc welding. These methods can meet the production requirements of the anchor chain to a certain extent, but also have many deficiencies. The traditional welding methods need manual operation and have a slow welding speed, and it is difficult to meet the demand of large-scale production.

[0003] A ship anchor chain automatic welding device is disclosed in a Chinese patent, which comprises a track plate, a base plate, a side plate, a positioning part and a welding mechanism. The welding mechanism comprises a transverse groove. Two left-right symmetrical and left-to-right transverse grooves are formed in the front end face of the side plate. A connecting plate is slidably arranged in the transverse groove through a transverse block. A mounting plate is fixedly arranged at the front end face of each connecting plate. The left mounting plate is in a vertical state, and the right mounting plate is in a horizontal state. A welding part one for welding a metal ring in the vertical direction is arranged on the left mounting plate. A welding part two for welding a metal ring in the horizontal direction is arranged on the right mounting plate. The welding part one comprises a horizontal bar. A horizontal bar is movably arranged on the upper end face of the left mounting plate through a shaft line from bottom to top. A sliding block groove one is formed in the lower end face of the horizontal bar from front to back. Two front-back symmetrical U-shaped plates one are slidably arranged in the sliding block groove one. A multi-degree-of-freedom manipulator with a welding head fixedly arranged in the U-shaped region of the U-shaped plate one. The two U-shaped plates one and the two U-shaped plates two are arranged to limit the metal ring. Therefore, the adjacent two metal rings are fixedly limited and kept parallel with the U-shaped plate one or the U-shaped plate two. The horizontal shaft can be easily put into the annular region of the metal ring. The stability in the welding process is improved. The horizontal shaft and the metal ring are kept in full contact. The straight line segments of the horizontal shaft and the metal ring are perpendicular to each other.

[0004] The two U-shaped plates one cooperate with each other, and the two U-shaped plates two cooperate with each other to limit the metal rings in them, so that the two adjacent metal rings are limited and fixed, and are parallel to the U-shaped plate one or the U-shaped plate two, facilitating the subsequent placement of the horizontal shaft into the annular region of the metal ring, improving the stability during the welding process, facilitating the full contact between the horizontal shaft and the metal ring, and making the straight line segments of the horizontal shaft and the metal ring perpendicular to each other. However, the anchor chain ring needs to be continuously moved during the processing to realize automatic welding. Due to the staggered arrangement structure of the adjacent chain rings, after the current chain ring is welded, the subsequent chain ring is moved to the welding position of the to-be-welded chain ring, thereby causing the welding position deviation, affecting the quality of the anchor chain.

DETAILED DESCRIPTION

[0029] In order to further understand the features, technical means and specific purposes and functions achieved by the present application, the present application is described in further detail below in combination with the drawings and specific embodiments.

[0030] Referring to Figures 1-8 As shown in the figure, the present application provides a chain ring welding equipment for ship anchor chain processing, which is used for welding the chain ring openings on the processed anchor chain together, comprising a main body 1, two first supports 11 are arranged on the top of the main body 1 along the length direction, and a plurality of support wheels 111 for supporting the anchor chain are distributed on the first supports 11. The design of the support wheels 111 can reduce the frictional resistance of the anchor chain during movement, ensure the smoothness of the movement of the anchor chain, and also play a certain guiding role to prevent the anchor chain from deviating during movement. The main body 1 is also provided with two chain ring adjusting assemblies 2 near the intersection of the two first supports 11 for adjusting the position of the anchor chain, and a welding assembly 3 for welding the chain ring openings of the anchor chain is arranged between the two chain ring adjusting assemblies 2. The chain ring adjusting assembly 2 comprises a rotating ring 21 which can rotate around its axis, and the rotating ring 21 can rotate around its axis. The side of the rotating ring 21 close to the welding assembly 3 is also uniformly distributed with limiting pieces 22 which can approach or move away from the center of the rotating ring 21 and are used for clamping the anchor chain. When the anchor chain needs to be clamped, the limiting pieces 22 approach the center of the rotating ring 21 to clamp and fix the anchor chain, preventing the anchor chain from shaking or shifting during adjustment and welding. When the anchor chain needs to be released, the limiting pieces 22 move away from the center of the rotating ring 21, so that the anchor chain can move freely.

[0031] In the ship anchor chain processing process, the processed anchor chain is placed on the first support 11 on the main body 1, and the anchor chain is supported by the supporting wheel 111 to roll, so that the anchor chain can move smoothly in the device. When the anchor chain moves between the two chain ring adjusting assemblies 2, the chain ring adjusting assembly 2 starts to work. The limiting piece 22 approaches the center of the rotating ring 21 to clamp and fix the anchor chain, and the rotating ring 21 rotates around its axis to drive the anchor chain to adjust the position preliminarily. Through the rotation of the rotating ring 21 and the clamping action of the limiting piece 22, the chain ring opening of the anchor chain is accurately aligned with the welding position of the welding assembly 3. After the chain ring opening position is adjusted, the welding assembly 3 starts to work, and the chain ring opening is welded together to complete the welding of the anchor chain. After welding, the limiting piece 22 moves away from the center of the rotating ring 21 to release the anchor chain, and the anchor chain continues to move. Through the cooperation of each component, the automatic welding of the chain ring opening of the ship anchor chain is realized, and the welding efficiency and welding quality are improved.

[0032] The clamping part of the limiting piece 22 is provided with an arc-shaped groove that can adapt to the side edge of the chain ring. When the limiting piece 22 moves towards the anchor chain, the arc-shaped groove of the clamping part of the limiting piece 22 can be clamped on the outer wall of the chain ring. Through the fit of the arc-shaped groove and the outer wall of the chain ring, the contact area between the limiting piece 22 and the chain ring is increased, thereby improving the stability and reliability of clamping. The side of the rotating ring 21 close to the limiting piece 22 is provided with a guide rail 211 that can make the limiting piece 22 keep linear motion. The guide rail 211 is in sliding fit with the limiting piece 22. The chain ring adjusting assembly 2 further comprises a telescopic driving piece 221 fixed on the rotating ring 21 and used for driving the limiting piece 22 to move reciprocally. When the telescopic driving piece 221 drives the limiting piece 22 to move, the limiting piece 22 moves linearly along the guide rail 211, so as to ensure that the limiting piece 22 can accurately approach or move away from the chain ring, and realize stable clamping and releasing actions. The output end of the telescopic driving piece 221 is fixedly connected with the end of the limiting piece 22 away from the clamping part.

[0033] The chain ring adjusting assembly 2 further comprises a housing fixed on the top of the main body 1, and a rotating driving mechanism used for driving the rotating ring 21 to rotate. The rotating driving mechanism comprises a plurality of driving wheels 231 arranged inside the housing and capable of contacting the outer edge of the rotating ring 21 and used for rotating the rotating ring 21. The rotating driving mechanism further comprises a first rotating driving piece 23 arranged outside the housing and used for rotating the driving wheel 231.

[0034] When the chain link needs to be clamped, the output end of the telescopic drive 221 is extended to push the limiting piece 22 along the guide rail 211 to move towards the chain link, so that the arc-shaped slot of the clamping part of the limiting piece 22 is clamped on the outer wall of the chain link, thereby achieving clamping and fixing of the chain link; when the chain link needs to be released, the output end of the telescopic drive 221 is retracted to pull the limiting piece 22 along the guide rail 211 away from the chain link, so that the arc-shaped slot is separated from the outer wall of the chain link, and the chain link returns to a free movement state. Through accurate control of the telescopic drive 221, the clamping and releasing actions of the limiting piece 22 can be quickly and accurately completed, thereby improving the working efficiency and automation degree of the chain link adjusting assembly 2.

[0035] The second support 12 is further provided on both sides of the top of the main body 1, and the guide wheel 121 capable of changing the direction of the anchor chain is rotatably arranged on the second support 12.

[0036] The winch assembly 4 capable of conveying the anchor chain is further provided on the bottom of the main body 1 close to the second support 12, and the winch assembly 4 comprises the connecting frame 42 fixed on the main body 1, and the winding drum 41 capable of conveying the anchor chain is rotatably arranged on the connecting frame 42. The helical blades 411 capable of limiting and guiding the anchor chain are arranged on the winding drum 41 along the length direction thereof, the anchor chain can be wound in the helical grooves formed between the helical blades 411, and the helical grooves are formed on the surface of the winding drum 41, so that the anchor chain can be wound in the helical grooves. When the winding drum 41 rotates, the helical grooves generate a forward pushing force and a lateral limiting force on the anchor chain. The forward pushing force moves the anchor chain along the axial direction of the winding drum 41 to realize the conveying function, and the lateral limiting force limits the movement of the anchor chain in the width direction of the winding drum 41 to ensure the stability and orderliness of the anchor chain conveying. At the same time, the design of the helical blades 411 can also increase the friction force between the anchor chain and the winding drum 41 to improve the reliability of the anchor chain conveying.

[0037] The winch assembly 4 further comprises the second rotary drive 44 for driving the winding drum 41 to rotate, and the winch assembly 4 further comprises the worm reducer 43 fixed on the connecting frame 42, the power input end of the worm reducer 43 is connected with the output end of the second rotary drive 44, and the power output end of the worm reducer 43 is connected with the winding drum 41.

[0038] In the winch assembly 4, the second rotary drive 44, the worm reducer 43 and the drum 41 cooperate with each other to complete the conveying task of the anchor chain. When the anchor chain needs to be conveyed, the second rotary drive 44 is started, and the second rotary drive 44 starts to rotate and outputs high-speed rotary power. This power is transmitted to the power input end of the worm reducer 43, and the worm reducer 43 transmits the processed power from the power output end to the drum 41 through the internal worm and worm gear engagement transmission, and then processes the high-speed power to increase the torque. After obtaining the appropriate speed and torque, the drum 41 starts to rotate, and the helical blades 411 on the surface of the drum 41 generate a pushing force on the anchor chain wound in the helical groove, so that the anchor chain moves along the axis direction of the drum 41, thereby realizing the conveying of the anchor chain. In the whole process, the worm reducer 43 plays a key role as a bridge, which not only ensures the stability of power transmission, but also has a self-locking function. After the drum 41 stops rotating, the anchor chain will not be affected by its own gravity to make the drum 41 rotate.

[0039] The welding assembly 3 comprises a welding head 33 capable of moving up and down and adjusting the angle, and further comprises a sliding member 321 rotationally connected with the welding head 33, and further comprises a support frame 31 fixed on the main body 1, and further comprises a linear movement mechanism 32 arranged on the support frame 31 and capable of driving the sliding member 321 to move up and down. The linear movement mechanism 32 can adopt various forms, such as a screw nut mechanism, a hydraulic cylinder or an air cylinder, etc. As long as the mechanism can make the welding head 33 move up and down.

[0040] In the ship anchor chain processing ring welding equipment, the various components of the welding assembly 3 work together to complete the welding task of the ring opening. When welding operation is needed, the sliding member 321 is driven by the linear movement mechanism 32 to move up and down, and the welding head 33 is adjusted to the appropriate height position. The angle of the welding head 33 can also be automatically adjusted. During the welding process, the welding head 33 emits high-temperature arc or laser energy to melt and fuse the metal at the ring opening.

[0041] The above embodiments only express one or several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
