Description

Technical Field

[0001] This invention belongs to the field of power distribution network robot technology, and particularly relates to a bypass cable splicing connection mechanism, method and bypass cable splicing robot. Background Technology

[0002] During the maintenance of overhead power distribution lines, in order to achieve uninterrupted power supply or to provide power to related equipment, the original overhead power distribution lines are used as the main lines, and bypass cables are spliced ​​on the main lines using splicing robots. Some of the cable splicing robots use male and female connectors to connect the main lines and bypass cables. First, the robot, including the female connector, is attached to the exposed conductive position of the main line. Then, the male connector of the bypass cable is hoisted to the female connector using rope hoisting or other methods and connected to the female connector.

[0003] However, during construction, after the male and female connectors are connected, the bypass cable will be dragged and repositioned. During these processes, the bypass cable will rotate, causing the entire robot to rotate and affecting its overall stability and the stability of the main cable connection. The rotation of the bypass cable will also cause the male and female connectors to rotate relative to each other. Although this rotation reduces the overall rotation of the robot, it not only affects the stability of the connection between the male and female connectors, but also makes the rope prone to knotting and breaking as it follows the rotation of the male connector. When the rope breaks, the male connector will fall off the female connector under the influence of gravity. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a bypass cable splicing mechanism, method, and robot. When the bypass cable drives the male connector to rotate within the female connector, conductivity is achieved through the wire contact between the arc-shaped power take-off component and the side wall of the male connector. This improves the rotational flexibility of the male connector, reduces the rotation of the entire splicing mechanism, and ensures the stability of the splicing structure itself and the connection stability between the entire splicing mechanism and the main cable. Furthermore, the wire contact conductivity between the arc-shaped power take-off component and the side wall of the male connector ensures both rotational flexibility and conductive stability. The engagement of the protrusion and groove provides axial limiting, preventing the male connector from falling out of the female connector when the cable breaks, thus ensuring safety.

[0005] To achieve the above objectives, in a first aspect, the present invention provides a connecting mechanism for bypass cable splicing, employing the following technical solution: A bypass cable splicing connection mechanism includes a connecting frame, and a rope winding assembly, a female end, and a clamping assembly disposed on the connecting frame; A rope passes through the female head, one end of which is connected to the rope winding assembly, and the other end is connected to the male head; the clamping assembly includes a telescopic rod, a clamping block disposed on the telescopic rod, and a power-taking block disposed on the clamping block; The power-collecting block can extend into the female connector through a pre-drilled hole on the side wall of the female connector; the end of the power-collecting block away from the clamping block is provided with a protrusion and an arc-shaped power-collecting component, and a groove is provided on the side wall of the male connector; after the male connector is inserted into the female connector, the protrusion engages in the groove, and the arc-shaped power-collecting component makes line contact with the side wall of the male connector; when the bypass cable drives the male connector to rotate in the female connector, conductivity is achieved through the line contact between the arc-shaped power-collecting component and the side wall of the male connector, and axial limiting is achieved through the engagement between the protrusion and the groove.

[0006] Furthermore, the arc-shaped power-generating component is an arc-shaped cylinder that is adapted to the male connector.

[0007] Furthermore, the male connector includes a bypass cable connection portion, a threaded rod disposed on the bypass cable connection portion, a threaded sleeve connected to the threaded rod, a receiving hole disposed within the threaded sleeve, and an insulating post fitted within the threaded sleeve; the inner diameter of the receiving hole at the end furthest from the threaded rod is smaller, and a limit block is provided at the end of the insulating post located near the threaded rod within the receiving hole; a through hole is provided on the axis of the insulating post, and after the rope passes through the through hole, a knot is provided within the receiving hole.

[0008] Furthermore, the female head is provided with a guide opening at one end near the male head, and the guide opening is an inverted conical opening.

[0009] Furthermore, a first position sensor and a second position sensor are respectively provided at both ends of the female head to detect the position of the male head in the middle.

[0010] Furthermore, when the first position sensor and the second position sensor detect that the male head is in the first position state, the protrusion is located at the lower end of the groove, and the rope winding assembly stops working; when the male head is detected to be in the second position state, the protrusion is located at the upper end of the groove, and the rope winding assembly works; if the male head is still in the second position state, it indicates that the rope is broken.

[0011] Furthermore, the clamping assembly includes a telescopic rod with one end hinged to the connecting frame via a first hinge, a connecting rod with the other end of the telescopic rod via a second hinge, a pressing block connected to the connecting rod via a fourth hinge, and a power-collecting block disposed on the pressing block.

[0012] Furthermore, the middle position of the connecting rod is hinged to the connecting frame via a third hinge member; the power-collecting block is slidably disposed within a pre-set groove on the connecting frame.

[0013] To achieve the above objectives, in a second aspect, the present invention also provides a connection method for bypass cable splicing, employing the following technical solution: A bypass cable splicing method uses a bypass cable splicing connection mechanism as described in the first aspect, comprising: after the male connector is inserted into the female connector, the protrusion engages with the groove, and the arc-shaped power-taking component makes line contact with the side wall of the male connector; when the bypass cable drives the male connector to rotate within the female connector, conductivity is achieved through the line contact between the arc-shaped power-taking component and the side wall of the male connector, and axial limiting is achieved through the engagement between the protrusion and the groove.

[0014] To achieve the above objectives, in a third aspect, the present invention also provides a bypass cable splicing robot, which adopts the following technical solution: A bypass cable splicing robot uses a bypass cable splicing connection mechanism as described in the first aspect.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, after the male connector is inserted into the female connector, the protrusion engages with the groove, and the arc-shaped power-collecting component makes contact with the side wall of the male connector. When the bypass cable drives the male connector to rotate within the female connector, conductivity is achieved through the contact between the arc-shaped power-collecting component and the side wall of the male connector. This improves the rotational flexibility of the male connector, reduces the rotation of the entire connection mechanism, and ensures the stability of the connection structure itself and the connection stability between the entire connection mechanism and the main line. Furthermore, the line contact conductivity between the arc-shaped power-collecting component and the side wall of the male connector ensures both rotational flexibility and conductivity stability. The engagement of the protrusion and the groove provides axial restraint, preventing the male connector from falling out of the female connector when the rope breaks, thus ensuring safety.

[0016] 2. In this invention, the arc-shaped power take-off component is an arc-shaped cylinder that is adapted to the male connector to realize the wire connection method. After being pressed, it can not only achieve stable conductivity, but also allow the male connector to rotate flexibly within the female connector.

[0017] 3. In this invention, the bypass cable connection part is connected to the male end through a threaded rod and a threaded sleeve, which facilitates the connection operation of the bypass cable; an insulating post is sleeved inside the threaded sleeve, and a through hole is opened in the axis of the insulating post. After the rope passes through the through hole, a knot is set in the receiving hole. When the male end rotates, the rope is relatively stationary in the through hole, which avoids the phenomenon of knotting or breaking of the rope due to rotation, thus improving safety.

[0018] 4. In this invention, the pressing assembly includes a telescopic rod with one end hinged to the connecting frame via a first hinge, a railing hinged to the other end of the telescopic rod via a second hinge, a pressing block connected to the connecting rod via a fourth hinge, and a power take-off block disposed on the pressing block; through the cooperation of the telescopic rod and the connecting rod structure, the width dimension of the connecting mechanism is reduced, the structure is compact, and it is convenient for on-site operation.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0023] Example 1: like Figure 1As shown, this embodiment provides a bypass cable splicing connection mechanism, including a connecting frame 1, and a rope winding assembly 2, a female connector 5, and a clamping assembly 6 disposed on the connecting frame 1. A rope 3 passes through the female connector 5, one end of the rope 3 is connected to the rope winding assembly 2, and the other end is connected to a male connector 4.

[0024] During operation, the connecting frame 1 is hoisted or lifted to the exposed position of the main line and connected to the main line; the female connector is connected to the main line through a wire, conductive plate or other conductive method; after the bypass cable is connected to the male connector 4, the rope winding assembly 2 winds the rope 3, thereby pulling the male connector 4 into the female connector 5, realizing the insertion and conduction of the male connector 4 and the female connector 5, thereby realizing the power supply of the bypass cable from the main line.

[0025] The specific structure of the connecting frame 1 can be designed according to the actual situation. The connecting frame 1 is provided with hollows to avoid swaying when the wind load is large. The connecting frame is provided with guide wheels, and the rope 3 is reversed through the guide wheel.

[0026] like Figure 2 As shown, optionally, the rope winding assembly 2 includes a housing 21, a motor 22, a gear 23, and a rotating shaft 24. The housing 21 can be mounted on the connecting frame 1, the motor 22 is mounted on the housing 21, and the output shaft of the motor 22 is provided with a drive gear capable of meshing with the gear 23; both the gear 23 and the rotating shaft 24 are rotatably mounted on the housing 21, and the rotating shaft 24 is connected to the gear 23.

[0027] During operation, the motor 22 rotates, which drives the dimension 23 and the rotating shaft 24 to rotate via the drive gear. The rotation of the rotating shaft 24 achieves the winding of the rope 3.

[0028] like Figure 1 As shown, the male connector 4 includes a bypass cable connection part 41, a threaded rod 42, a threaded sleeve 43, a receiving hole 44, a groove 45, and an insulating post 46, etc.; the insulating post 46 includes a post body 462 and a limiting block 461 disposed at one end of the post body 462.

[0029] The bypass cable connector 41 is used to connect bypass cables and can be configured as a conductor. The threaded rod 42 has an external thread, and the threaded sleeve 43 has an internal thread that matches the external thread. The cooperation between the threaded rod 42 and the threaded sleeve 43 facilitates the connection of bypass cables to the bypass cable connector 41. In some special cases, the male end of the bypass cable connector 41 can be removed, a bypass cable connected, and then the connection made. The receiving hole 44 includes two parts: one part has a larger inner diameter to accommodate the knot 7 on the rope 3, and the other part accommodates the limiting block 461. The groove 45 is an annular groove used to engage with the protrusion 681 in the clamping assembly 6 to achieve axial limiting. The column 462 has a through hole at its axial center; the rope 3 passes through the through hole and is fitted with a knot 7 to achieve limiting.

[0030] Understandably, the bypass cable connection part 41 is connected to the male connector 4 through the threaded rod 42 and the threaded sleeve 43, which facilitates the connection operation of the bypass cable, etc. The threaded sleeve 43 is fitted with an insulating post 46, and the insulating post 46 has a through hole in its axis. After the rope 3 passes through the through hole, a knot is set in the receiving hole 44. When the male connector 4 rotates, the rope 3 remains relatively stationary in the through hole, which avoids the rope 3 from knotting or breaking due to rotation, thus improving safety.

[0031] like Figure 2 As shown, the female head 5 includes a female head connecting plate 51, a guide port 52, a first position sensor 53, and a second position sensor 54.

[0032] The female connector plate 51 is provided so that the female connector 5 can be mounted on the connecting frame 1 by means of bolt connection or welding. A guide opening 52 is provided at one end of the female connector 5 near the male connector 4. The guide opening 52 is an inverted conical opening, which facilitates the insertion of the male connector 4 into the female connector 5. A first position sensor 53 and a second position sensor 54 are respectively provided at both ends of the female connector to detect the position of the male connector. Optionally, when the first position sensor 53 and the second position sensor 54 detect that the male connector is in the first position, the protrusion 681 is located at the lower end of the groove 45, indicating that the male connector 4 has reached the working position, and the rope winding assembly 41 stops working. When the male connector 4 is detected to be in the second position, the protrusion 681 is located at the upper end of the groove 45, indicating that the male connector 4 has moved outward under gravity, and the rope winding assembly 41 works. If the male connector is still in the second position, it means that the rope 3 has no effect on the male connector 4, and the rope breaks.

[0033] like Figure 2 , Figure 3 and Figure 4As shown, the clamping assembly 6 includes a telescopic rod 62 with one end hinged to the connecting frame 1 via a first hinge 61, a connecting rod 64 with the other end of the telescopic rod 62 via a second hinge 63, a pressing block 67 connected to the connecting rod 64 via a fourth hinge 66, and a power-collecting block 68 disposed on the pressing block 67. It is understood that the power-collecting block 68 is electrically connected to the main line via a wire or other conductor. The telescopic rod 62 can be an electric telescopic rod or other telescopic component, and the telescopic rod 62 is connected to a controller to control the pressure. The connecting rod 64 is hinged to the connecting frame 1 at its middle position via a third hinge 65; the power-collecting block 68 is slidably disposed within a pre-set groove 69 on the connecting frame 1. The clamping assembly 6, through the cooperation of the telescopic rod 62 and the connecting rod 64, reduces the width of the connecting mechanism, resulting in a compact structure that facilitates on-site operation. If the connecting mechanism is too large, it will be interfered with by cables, power equipment, etc., on-site, which is detrimental to operation. In another embodiment, the arc-shaped power take-up component 682 has an arc surface. The traditional connection method is to connect metal parts by means of threads or tapered surfaces. This method is either inefficient or the connection is easy to loosen. The connection method of the clamping component 6 greatly improves the work efficiency. By clamping the male head 4 from the side, the arc surface is in contact with the arc surface of the male head, which increases the contact area between the components, improves the current flow performance, and reduces the current flow temperature.

[0034] In one embodiment, the pressure of the telescopic rod 62 controlled by the controller is determined as follows: Given the weight of the object to be lifted (approximately 20 kg, no impact), the coefficient of friction between copper and aluminum alloy (the two contacting objects) is approximately 0.6, the push rod pull force is 200 N, and the ratio of the connecting rod's power arm to its resistance arm is 2.5. Therefore, the pressure exerted by the push rod on the slider is 200 N * 2.5 = 500 N. Given the coefficient of friction is 0.6, f = μN = 0.6 * 500 = 300 N. The weight of the object is 20 kg, so the object's weight G = mg = 20 kg * 10 N / kg = 200 N. Therefore, 300 N > 250 N, allowing the weight to be tightened. When the pressure is high, due to the high-pressure environment, some structural components require insulation, and lower-strength plastic parts may be used. Therefore, high pressure can cause irreversible structural deformation, affecting operational accuracy and reducing machine lifespan. When the pressure is low, the weight cannot be tightened, leading to poor contact between the male connector 4 and the female connector 5, affecting the normal use of the tool.

[0035] Example 2: This embodiment provides a bypass cable splicing method, which uses the bypass cable splicing connection mechanism as described in Embodiment 1, including: after the male connector 4 is inserted into the female connector 5, the protrusion 681 is engaged in the groove 45, and the arc-shaped power-taking component makes line contact with the side wall of the male connector 4; when the bypass cable drives the male connector 4 to rotate in the female connector 5, conductivity is achieved through the line contact between the arc-shaped power-taking component and the side wall of the male connector 4, and axial limiting is achieved through the engagement between the protrusion 681 and the groove 45.

[0036] Example 3: This embodiment provides a bypass cable splicing robot, which uses the bypass cable splicing connection mechanism as described in Embodiment 1. The bypass cable splicing robot also includes a main line connection mechanism, and other mechanisms can be implemented using conventional technologies, which will not be described in detail here.

[0037] The above description is merely a preferred embodiment of this practice and is not intended to limit the scope of this practice. Various modifications and variations can be made to this practice by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this practice should be included within the protection scope of this practice.
