Description

Technical Field

[0001] The present invention relates to the technical field of docking equipment, and in particular to a docking device and a docking method for a plug and a socket. Background Art

[0002] Docking equipment is a device used to connect two or more components or systems so that they can be tightly combined and work normally. During the operation of the marine automatic charging system, the plug and socket are large in size and need to be combined using crane equipment, so docking equipment is often required to assist in completion.

[0003] The existing docking equipment for marine plugs and sockets mostly uses a crane to move the plug when in use, so that the plug is moved to the inside of the correction bucket for assembly, so that the connecting end of the plug passes through the hole inside the correction bucket, and then the correction bucket is driven by a hydraulic cylinder to move along the surface of the guide rod toward the base, so that the connecting end of the plug moves to the inside of the port inserted into the socket, so as to achieve rapid docking of the plug and the socket.

[0004] However, since the plug will shake during the process of being inserted into the correction bucket, the plug will collide with the inner wall of the correction bucket during the process of being combined with the correction bucket, causing the inner wall of the correction bucket to be dented or damaged, affecting the normal use of the correction bucket. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a docking device and a docking method for a plug and a socket.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a docking device for a plug and a socket, comprising a base, a guide rod is arranged on one side of the base, a correction bucket is arranged on one side of the guide rod, a hydraulic cylinder is arranged on the side of the base close to the correction bucket, the output end of the hydraulic cylinder is connected to the correction bucket, a socket box is arranged on the side of the base close to the correction bucket, a plug body is arranged on one side of the correction bucket, an anti-collision device is arranged on one side of the correction bucket, an auxiliary device is arranged on one side of the correction bucket, the anti-collision device comprises a rectangular cylinder, the rectangular cylinder is fixedly connected to the correction bucket, and the inner wall of the rectangular cylinder is connected to the inner wall of the correction bucket A circular hole is opened on one side of the rectangular cylinder, and a round rod is slidably connected to the inner wall of the circular hole, and a baffle is fixedly connected to one side of the round rod, and the surface of the baffle is larger than the inner wall of the circular hole, and a push block is fixedly connected to the side of the round rod away from the baffle, and the surface of the push block is slidably connected to the inner wall of the rectangular cylinder. A spring is sleeved on the surface of the round rod, one end of the spring is fixedly connected to the push block, and the other end of the spring is fixedly connected to the inner wall of the rectangular cylinder, and an arc plate is fixedly connected to the side of the push block away from the round rod, and the cross-section of the arc plate is concave, and a plurality of rollers are arranged inside the arc plate, and the surfaces of the plurality of rollers are higher than the surface of the arc plate.

[0007] The effect achieved by the above-mentioned components is: by setting an anti-collision device, when the plug body is moved by an external crane to the position for insertion into the correction bucket, the surface of the plug body is fitted with multiple rollers on the arc plate, and under the action of the rotation of the rollers and the movability of the arc plate, the plug body can continue to be inserted into the correction bucket. At this time, under the reaction force of the spring, the spring pushes the push block to move in the direction away from the inside of the rectangular tube, so that the push block pushes the arc plate to move in the direction away from the inside of the rectangular tube, so that the arc plate cooperates with multiple rollers to push the plug body inserted into the correction bucket to move in the direction away from the inner wall of the correction bucket, so that the arc plate blocks the plug body inserted into the correction bucket, thereby achieving an anti-collision effect, reducing the collision of the plug body with the inner wall of the correction bucket after being directly inserted into the correction bucket, causing damage or deformation of the inner wall of the correction bucket, affecting the normal use of the correction bucket, and improving the safety and life of the correction bucket.

[0008] Preferably, a plurality of rubber strips are fixedly connected to the surfaces of the plurality of rollers, and the plurality of rubber strips are arranged at equal distances.

[0009] The effect achieved by the above components is: by arranging the rubber strip, the rubber strip can separate the surface of the roller from the surface of the plug body, thereby reducing the situation where the plug body collides with the surface of the roller and causes significant damage to the surface.

[0010] Preferably, a limiting groove is provided on the inner wall of the rectangular tube, a limiting block is fixedly connected to one side of the push block, the surface of the limiting block is slidably connected to the inner wall of the limiting groove, and the surface size and shape of the limiting block are adapted to the size and shape of the inner wall of the limiting groove.

[0011] The effect achieved by the above components is: by setting the limit block and the limit groove, the limit block can be located inside the limit groove to assist in limiting the push block and the arc plate, thereby reducing the shaking of the push block during use and further improving the stability of the push block and the arc plate.

[0012] Preferably, a U-shaped rod is fixedly connected to one side of the rectangular tube, the U-shaped rod is sleeved on the surface of the baffle, and a rubber column is fixedly connected to the inner wall of the U-shaped rod, and the surface of the rubber column is in contact with the surface of the baffle.

[0013] The effect achieved by the above components is: by arranging the U-shaped rod and the rubber column, when the plug body squeezes and collides with the surface of the arc plate, the arc plate pushes the round rod to move in the direction close to the U-shaped rod, and the round rod pushes the baffle to move, so that the rubber column cooperates with the U-shaped rod to assist in intercepting and buffering the moving baffle, thereby reducing the direct impact force on the arc plate and reducing the collision force on the arc plate, which causes the push block to squeeze the spring more when it moves in the direction close to the inside of the rectangular tube, causing the spring to deform and be damaged, affecting the normal use of the spring.

[0014] Preferably, a reinforcement block is fixedly connected to one side of the U-shaped rod close to the rectangular tube, and the reinforcement block is fixedly connected to the rectangular tube.

[0015] The effect achieved by the above components is: by setting the reinforcement block, the reinforcement block can strengthen the connection between the U-shaped rod and the rectangular tube, reduce the stress on the U-shaped rod and the separation from the rectangular tube, and improve the stability of the U-shaped rod.

[0016] Preferably, the auxiliary device includes a trapezoidal cylinder, the inner wall of which is provided with a circular through hole, a bolt is provided inside the circular through hole, a threaded groove is provided on one side of the correction bucket, the surface of the bolt is threadedly connected to the inner wall of the threaded groove, and a wear-resistant plate is fixedly connected to one side of the trapezoidal cylinder.

[0017] The effect achieved by the above-mentioned components is: by setting an auxiliary device, first manually move the trapezoidal cylinder so that the trapezoidal cylinder drives the wear-resistant plate composed of a low-carbon steel plate and an alloy wear-resistant layer to move. When the trapezoidal cylinder moves to a position that fits the surface of the entrance of the correction bucket, the inner wall of the threaded groove coincides with the inner wall of the round hole. At this time, the bolt is rotated by a tool so that the bolt is rotated into the round hole and the inner position of the threaded groove to fix the position of the trapezoidal cylinder, thereby completing the assembly of the trapezoidal cylinder and the correction bucket. When the plug body is inserted into the correction bucket, the plug body is intercepted by the trapezoidal cylinder when it is close to the entrance of the correction bucket, thereby quickly guiding the plug body into the correction bucket, reducing the situation where the plug body is difficult to insert into the correction bucket due to the small size of the entrance of the correction bucket, and at the same time reducing the collision of the plug body with its surface when inserted into the correction bucket, thereby improving the convenience and efficiency of inserting the plug body into the correction bucket.

[0018] Preferably, a plurality of support plates are fixedly connected to the inner wall of the trapezoidal cylinder, and the plurality of support plates are arranged at equal distances.

[0019] The effect achieved by the above components is: by setting the support plate, the support plate can provide auxiliary support to the inside of the trapezoidal tube, thereby improving the strength of the trapezoidal tube and reducing the possibility of dents or damage to the trapezoidal tube when it is collided with the plug body.

[0020] Preferably, a method for docking a plug and a socket comprises the following steps:

[0021] S1. First, the plug body is driven to move by an external crane. When the plug body moves to a position where it is completely inserted into the correction bucket, the connecting end of the plug body passes through the hole inside the correction bucket, thereby achieving the merging of the plug body and the correction bucket.

[0022] S2. At this time, the hydraulic cylinder is started, so that the hydraulic cylinder drives the correction bucket to move along the surface of the guide rod toward the base, so that the correction bucket drives the internal plug body to move together. When the connecting end of the plug body moves to the internal position of the port inserted into the socket box, the quick docking of the plug body and the socket box is completed.

[0023] Compared with the prior art, the advantages and positive effects of the present invention are:

[0024] In the present invention, an anti-collision device is provided to block the plug body inserted into the correction bucket, so that the plug body does not directly collide with the inner wall of the correction bucket, thereby reducing the collision of the plug body with the inner wall of the correction bucket after being directly inserted into the correction bucket, causing damage or deformation of the inner wall of the correction bucket, affecting the normal use of the correction bucket, and improving the safety and life of the correction bucket.

By setting the anti-collision device 7, when the plug body 6 is moved by the external crane to the position of inserting into the correction bucket 3, the surface of the plug body 6 is fitted with the plurality of rollers 712 on the arc plate 711. Under the rotation of the rollers 712 and the mobility of the arc plate 711, the plug body 6 can continue to be inserted into the correction bucket 3.

By arranging the U-shaped rod 73 and the rubber column 74, when the plug body 6 squeezes and collides with the surface of the arc plate 711, the arc plate 711 pushes the round rod 77 to move in the direction close to the U-shaped rod 73, so that the round rod 77 pushes the baffle 79 to move, so that the rubber column 74 cooperates with the U-shaped rod 73 to assist in intercepting and buffering the moving baffle 79, thereby reducing the direct impact on the arc plate 711. The impact force is reduced, and the collision force received by the arc plate 711 is large, resulting in a large squeezing force on the spring 78 when the push block 710 moves toward the direction close to the inside of the rectangular tube 71, causing the spring 78 to be deformed and damaged, affecting the normal use of the spring 78. A reinforcement block 75 is fixedly connected to the side of the U-shaped rod 73 close to the rectangular tube 71, and the reinforcement block 75 is fixedly connected to the rectangular tube 71.
