Description

Technical Field

[0001] The invention relates to a cable pipe opening butt joint technology, in particular to a cable pipe opening butt joint processing device. Background Art

[0002] In power engineering, underground pipe networks, and industrial wiring, cable conduits serve as a protective layer for power and signal transmission, and their installation quality directly impacts the safety and reliability of the system. When two sets of cable conduits need to be joined due to insufficient length, sleeves are typically installed on the outside of the cable conduits for welding to avoid direct welding to the cable conduits, which could cause penetration or holes. However, existing technologies present the following unconventional technical issues in the fixing and welding of sleeves and cable conduits:

[0003] Traditional clamping devices often use rigid claws or fixed clamps, which are difficult to adapt to scenarios where the diameters of the two sets of cable tubes vary greatly. For example, when one end of the cable tube is connected to the sleeve and the other end is not, the clamping parts are prone to causing the sleeve to shift or uneven force on the cable tube due to inconsistent diameters. In addition, when the diameters of the cable tubes vary greatly, traditional clamping devices require frequent fixture replacement or manual adjustment, which is time-consuming, and the clamping force is unevenly distributed, reducing the fit between the sleeve and the cable tube. In addition, the relative position of the sleeve and the cable tube must be corrected multiple times before welding, which is a cumbersome process and difficult to meet the needs of high-efficiency construction. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to solve the problem that the welded sleeve of the cable pipe cannot be effectively fixed.

[0005] The above technical problems are solved by the following technical solution: The present invention provides a cable pipe opening docking processing device, which includes a clamping plate unit including multiple sets of clamping rings, a clamping member fixedly inserted into the inner axis of the clamping ring, a fastener fixedly provided at one end of the clamping ring, and an extrusion assembly penetrating the two ends of the clamping ring;

[0006] A docking unit, connected to the inner side of the clamping plate unit, comprising a half gear ring, a spot welder fixedly arranged on the end surface of the half gear ring, and a transmission member arranged at the bottom of the half gear ring;

[0007] Two groups of cable tubes and a sleeve sleeved between the cable tubes.

[0008] In a preferred embodiment of the cable pipe opening docking processing device of the present invention, the clamping ring includes a left clamping ring and a right clamping ring sleeved on the outside of the cable pipe and symmetrical to the left clamping ring;

[0009] The left clamping ring and the right clamping ring together clamp the cable tube and the outer side of the sleeve.

[0010] In a preferred embodiment of the cable pipe opening docking processing device of the present invention: the left clamping ring includes an opening and closing clamping plate, a baffle threadedly connected to the outside of the opening and closing clamping plate, and an arc plate arranged at the end of the baffle.

[0011] In a preferred embodiment of the cable pipe opening docking processing device of the present invention: the clamping member includes a limiting ring threadedly connected to the upper and lower sides of the opening and closing clamp, and a plurality of spring plates arranged at the upper and lower ends of the limiting ring.

[0012] In a preferred embodiment of the cable pipe opening docking processing device of the present invention: the transmission member includes a gear set engaged with the bottom of the half gear ring, and a synchronous belt connected to the gear set;

[0013] The half gear ring includes a connecting platform protruding from one end portion thereof.

[0014] In a preferred embodiment of the cable pipe opening docking processing device of the present invention: the spring plate includes a connecting end inserted into the bottom or end of the limiting ring, a plate body protruding from the end of the connecting end, and a pressing plate protruding from the inner side of the end of the plate body.

[0015] In a preferred embodiment of the cable pipe opening docking processing device of the present invention, the plate body includes a curved section that contacts the outer wall of the cable pipe, and an extended section that extends outward.

[0016] In a preferred embodiment of the cable pipe opening docking processing device of the present invention: the extrusion assembly includes a push rod that abuts against the extension section, a spring sleeved on the push rod body, and an adjustment member arranged on the outside of the push rod.

[0017] In a preferred embodiment of the cable pipe opening docking processing device of the present invention: the push rod presses the extension section into the pipe, causing one side of the pressing plate to contact the sleeve.

[0018] In a preferred embodiment of the cable pipe opening docking processing device of the present invention: the end of the abutting rod is a screw rod;

[0019] The adjusting member includes a snap ring protruding from the side edges of the baffle and the arc plate, a docking ring matched with the snap ring, and a nut slidably connected to the end of the docking ring.

[0020] The beneficial effect of the present invention is that the device realizes dual fixation of the cable tube and the sleeve through the coordinated action of the clamping part and the extrusion assembly: the elastic structure of the clamping part can adapt to cable tubes of different diameters, and cooperate with the axial adjustment function of the push rod in the extrusion assembly to dynamically compensate for the diameter difference, so that the pressing plate obliquely contacts the outer wall of the sleeve, ensuring that the sleeve and the cable tube are not displaced during the welding process.

[0021] The opening and closing splints and clamping parts of the splint unit are designed to achieve simultaneous clamping and closing actions, significantly shortening operation time; the adjustment structure of the spot welder supports rapid adaptation to cable pipes of different diameters, while the adjustment function of the extrusion component can accurately control the clamping force.

[0030] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below with reference to specific embodiments and the accompanying drawings.

[0031] The terms used in the present invention are those commonly used in the art in view of the functions of the present invention, but these terms may vary according to the intentions of those skilled in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as the meanings of the terms and the overall description of the present invention.

[0032] Reference Figures 1 to 7This embodiment provides a cable conduit port docking processing device, comprising a clamping plate unit 1, comprising a plurality of clamping rings 11, a clamping member 12 fixedly inserted into the inner axis of the clamping ring 11, a fastener 13 fixedly provided at one end of the clamping ring 11, and an extrusion assembly 14 penetrating the ends of both sides of the clamping ring 11;

[0033] The docking unit 2 is connected to the inner side of the splint unit 1. The docking unit 2 includes a half gear ring 21, a spot welder 22 fixedly arranged on the end surface of the half gear ring 21, and a transmission member 23 arranged at the bottom of the half gear ring 21;

[0034] Two sets of cable tubes 31 and a sleeve 32 sleeved between the cable tubes 31 .

[0035] In one embodiment provided in the present application, the clamping ring 11 includes a left clamping ring 111 and a right clamping ring 112 sleeved on the outside of the cable tube 31 and symmetrical to the left clamping ring 111;

[0036] The left clamping ring 111 and the right clamping ring 112 clamp the cable tube 31 and the outer side of the sleeve 32 together.

[0037] In one embodiment provided in the present application, the left clamp ring 111 includes an opening and closing clamp plate 1111 , a baffle 1112 threadedly connected to the outside of the opening and closing clamp plate 1111 , and an arc plate 1113 arranged at the end of the baffle 1112 .

[0038] In this embodiment, the clamping ring 11 consists of a left clamping ring 111 and a right clamping ring 112. The left and right clamping rings 111 and 112 have identical structures. By opening and closing the clamping member 12 within the clamping ring, the two sets of cable tubes 31 to be connected are welded together using the sleeve 32. The clamping member 12 can accommodate cable tubes 31 or sleeves 32 of varying sizes within a certain range.

[0039] Furthermore, the left clamping ring 111 has an opening and closing function and is locked by a fastener 13 threadedly connected to the side walls of the left clamping ring 111 and the right clamping ring 112. The left clamping ring 111 is composed of an opening and closing splint 1111 with an opening and closing function, a baffle 1112 clamped at the bottom of the opening and closing splint 1111, and an arc plate 1113 clamped at the end of the opening and closing splint 1111. Among them, the opening and closing splint 1111 is composed of plates that are hinged together and can form a circular groove inside, and the opening and closing effect is achieved by the hinged action on one side. The clamping member 12 is connected to the inner bolts of the left clamping ring 111 and the right clamping ring 112. The clamping member 12 is adapted to the opening and closing splint 1111 and is connected to the axis of the opening and closing splint 1111 by a notch bolt. The clamping member 12 is therefore a vertically symmetrical structure, and a clamping mechanism is embedded in the inner cavity of the clamping member 12 for clamping the outer diameter of the cable tube 31 and fixing the sleeve 332 in the inner cavity of the clamping member 12 .

[0040] The clamping member 12 is composed of a vertically symmetrical ring body, and an extrusion plate can be embedded inside the ring body. The extrusion plate's own elastic deformation acts on the outer diameter of the cable tube 31 to achieve elastic extrusion and fixation. The deformation of the clamping member 12 acts on the extrusion assembly 14, which can fix the sleeve 32 outside the cable tube 31. This allows the clamping member 12 to clamp the cable tube 31 while the opening and closing clamping plate 1111 is closed.

[0041] Furthermore, four groups of extrusion components 14 are slidably connected to the left and right sides of the clamping member 12. The extrusion components 14 slide on the ring body of the clamping member 12 to close the ring body of the clamping member 12 and clamp the cable tube 31.

[0042] Furthermore, the docking unit 2 is integrated into the inner side of the splint unit 1 to achieve rotational welding of the cable tube 31 and the sleeve 32. The specific structure includes: a semi-toothed ring 21 is symmetrically arranged on the inner side of the splint unit 1, with a protruding connection platform 211 at the end for fixing the spot welder 22; it is connected to the inner wall of the opening and closing splint 1111 through a slide rail and has rotational freedom. The spot welder 22 is fixed to the connection platform 211 of the semi-toothed ring 21, and its welding gun can adapt to cable tubes 31 of different diameters through a straight slot adjustment hole (±5mm); through the rotation of the semi-toothed ring 21, a semi-circular motion is performed with the cable tube 31 as the center, completing the continuous welding of the sleeve 32 and the side seam of the cable tube 31. The transmission member 23 is located at the bottom of the splint unit 1 and consists of two sets of gear sets 231 and a set of synchronous belts 232; the gear set 231 is engaged with the farthest end of the bottom of the semi-toothed ring 21, and power synchronization is achieved through the synchronous belt 232, driving the semi-toothed ring 21 to a maximum rotation angle of ≥180°.

[0043] By opening the left clamping ring 111 and the right clamping ring 112, the cable tube 31 with the sleeve 32 and the cable tube 31 without the sleeve 32 are respectively inserted into the inner side of the clamping unit 1; after closing the clamping unit 1, the clamping part 12 fits the outer diameter of the cable tube 31 through the elastic extrusion plate, and at the same time, the extrusion component 14 adjusts the extension length of the support rod 141 so that the pressing plate 1223 obliquely contacts the outer wall of the sleeve 32, thereby achieving double fixation.

[0044] In summary, this device synchronizes the closing of the clamping unit 1 with the welding action, shortening the single operation time by 50% compared to traditional methods and allowing for rapid adaptation of multiple cable tube specifications. Pre-welding misalignment detection and the design of the sleeve 32 support effectively prevent cable tube 31 breakdown and welding displacement.

[0045] Reference Figures 1 to 3 As an optional embodiment, the docking unit 2 is connected to the inner side of the splint unit 1. The docking unit 2 includes a half gear ring 21, a spot welder 22 fixedly arranged on the end surface of the half gear ring 21, and a transmission member 23 arranged at the bottom of the half gear ring 21;

[0046] Two sets of cable tubes 31 and a sleeve 32 sleeved between the cable tubes 31 .

[0047] In one embodiment provided in the present application, the transmission member 23 includes a gear set 231 meshed with the bottom of the half gear ring 21, and a synchronous belt 232 connected to the gear set 231;

[0048] The half gear ring 21 includes a connecting platform 211 protruding from one end portion thereof.

[0049] In this embodiment, the half-gear rings 21 are attached to the inner sidewalls of the opening and closing clamps 1111 using slide rails. Two symmetrical sets of half-gear rings 21 are arranged, each with a connecting platform 211 protruding outward from one end. Two sets of connecting platforms 221 bolt the spot welder 22 to the inner sides of the two sets of half-gear rings 21. By synchronously driving the half-gear rings 21 on both sides to rotate, the spot welder 22 rotates in a semicircle around the cable tube 31, performing welding.

[0050] Preferably, the bolt connection hole on the connecting platform 211 and the spot welder 22 is a straight slot, so that the distance between the spot welder 22 and the cable pipe can be adjusted.

[0051] Preferably, the transmission member 23 is arranged at the bottom of the device and is wrapped inside by two sets of opening and closing clamps 1111. The transmission member 23 is composed of two sets of gear sets 231 and a synchronous belt 232 connected to the tooth surfaces of the two sets of gear sets 231. The synchronous belt 232 can realize the transmission between the two sets of gear sets 231.

[0052] Each gear set 231 consists of two sets of gears meshed at the bottom of the half gear ring 21 and a transmission shaft inserted into the gear axis. The two gear sets 231 are respectively meshed at the left and right farthest ends of the bottom of the half gear ring 21 to achieve maximum rotation of the half gear ring 21 driven by the gear set 231.

[0053] When in use, the left clamp ring 111 and the right clamp ring 112 are opened at the same time, and the cable tube 31 with the sleeve 32 on one side and the cable tube 31 without the sleeve 32 are installed on the inner sides of the left clamp ring 111 and the right clamp ring 112. Then, the left clamp ring 111 and the right clamp ring 112 are closed at the same time, and the clamping parts 12 on the inner sides of the left clamp ring 111 and the right clamp ring 112 are squeezed and deformed, and the cable tube 31 is squeezed and limited by itself, and is clamped by the clamping parts 12 on the inner sides of the clamp ring 11; then the fastener 13 is used to lock it.

[0054] Before welding, you should ensure that the butt joint gap of the cable tube 31 deviates from the front end or rear end of the spot welder 22, and align the tail end of the sleeve 32 and the seam of the cable tube 31 with the welding gun of the spot welder 22, and ensure that the spot welder 22 uses the sleeve 32 to weld on the two groups of cable tubes 31, so as to achieve the butt joint of the cable tubes 31 while avoiding welding breakdown of the cable tubes 31.

[0055] After being fixed by spot welding with the spot welder 22 , the driving gear set 231 drives the half gear ring 21 and the spot welder 22 to move in a circular motion, thereby welding the side seams of the sleeve 32 and the cable tube 31 .

[0056] Reference Figures 4 and 5 As an optional embodiment, the clamping member 12 includes a limiting ring 121 threadedly connected to the upper and lower sides of the opening and closing clamp 1111, and a plurality of sets of spring plates 122 arranged at the upper and lower ends of the limiting ring 121.

[0057] In this embodiment, Figure 4 As shown. The clamping member 12 is composed of a symmetrical structure, one of which is two groups of limiting rings 121 bolted to the upper and lower sides of the opening and closing splint 1111 respectively; the other is a spring plate 122 bolted into the middle of the limiting ring body. The limiting ring 121 is a semi-ring body that fits the annular groove of the opening and closing splint 1111. The spring plate 122 is inserted into the middle part of the semi-ring body of the limiting ring 121, and is bolted through and connected to the ring body of the limiting ring 121 to achieve an interference fit. The spring plates 122 are bolted symmetrically on both sides to a group of limiting rings 121, and the cross-section of each group of spring plates 122 is a quarter ellipse, so that the two groups of spring plates 122 are limited on a group of limiting rings 121, forming an extrusion surface with a small angle that can act on pipes of different diameters.

[0058] Because the ring formed by the four sets of spring plates 122 is elliptical or irregularly shaped, when the upper and lower surfaces of the opening and closing clamping plate 1111 are closed, the two sets of limit rings 121 also close into a full circle, and the extrusion surface formed by the four sets of spring plates 122 directly compresses the outer wall of the pipe. The small angle surface of the two sets of spring plates 122 compresses the inner pipe, achieving multi-diameter pipe clamping. Clamping is achieved when the opening and closing clamping plate 1111 is closed, reducing operation time.

[0059] Preferably, the spring plate 122 can be made of 65Mn or 60Si2Mn spring steel, which has excellent elasticity and fatigue resistance, can ensure that the spring plate maintains deformation recovery ability during repeated clamping operations, and is suitable for working conditions where the diameter is frequently adjusted; it can also be made of materials with good elasticity such as 304 or 17-4PH stainless steel.

[0060] In one embodiment provided in the present application, the spring plate 122 includes a connecting end 1221 inserted into the bottom or end of the limiting ring 121, a plate body 1222 protruding from the end of the connecting end 1221, and a pressing plate 1223 protruding from the inner side of the end of the plate body 1222.

[0061] In one embodiment provided in the present application, the plate body 1222 includes a bent section M that contacts the outer wall of the cable tube 31 , and an extended section N that extends outward.

[0062] In this embodiment, Figure 4 As shown. The spring plate 122 consists of a connecting end 1221 inserted into the middle part of the ring body of the limiting ring 121, a plate body 1222 extending to the inner side of the limiting ring 121, and a pressing plate 1223 protruding from one side of the end of the plate body 1222. Among them, the connecting end 1221 is connected to the bottom of the limiting ring 121 by a bolt passing through the outer side of the limiting ring 121, and its plate body 1222 extends outward from the curved section M to form an extension section N. When the limiting ring 121 is closed, the pipe clamped on its inner side will be squeezed on the curved section M of the plate body 1222, squeezing the originally smaller opening of the extension section N outward, so that the pressing plate 1223 at its end also expands outward. An extrusion assembly 14 is installed on the baffle 1112 and the arc plate 1113 outside the extension section N. The extrusion assembly 14 limits the opening and closing degree of the spring plate 122, thereby improving the clamping of the spring plate 122 on the pipes of different sizes inside it.

[0063] The working principle of the clamping member 12 is based on the coordinated deformation and elastic recovery characteristics of the mechanical structure. When the opening and closing clamps 1111 are closed, the semi-annular retaining rings 121 on both sides gradually close into a complete annular structure under the pressure of the clamps. At this time, the spring plate 122 inside the retaining ring 121 undergoes elastic deformation under the driving force of the clamp closing:

[0064] First, the curved section M of the spring plate 122 fits against the outer wall of the pipe, causing local compression or stretching due to the difference in pipe diameters, forcing the extended section N to expand outward, pushing the pressing plate 1223 to apply pressure to the outer wall of the pipe;

[0065] Secondly, the quarter-elliptical cross-section design of the spring plate 122 enables it to form a small-angle extrusion surface when closed, and achieves adaptive clamping of pipes of different diameters through the difference in material elastic modulus, such as the high elastic recovery ability of 65Mn spring steel;

[0066] Next, the extrusion assembly 14 limits the further opening and closing of the spring plate 122 by passing through the limiting grooves or threaded holes in the baffle 1112 and the arc plate 1113, ensuring that the clamping force acts stably on the pipe surface to prevent loosening due to vibration or external force.

[0067] In summary, the clamping member 12 of this embodiment, through the quarter-elliptical cross-section design and elastic deformation properties of the spring plate 122, can adapt to cable pipes 31 within the range of Φ30-Φ50mm without manual clamp replacement. The small-angle extrusion surface evenly distributes the clamping force, avoiding the localized stress concentration and surface damage caused by traditional claw-type clamps. The closing action of the opening and closing clamp 1111 is completed simultaneously with the clamping process, shortening the time of a single clamping operation.

[0068] Reference Figures 4 to 7As an optional embodiment, the extrusion assembly 14 includes a push rod 141 that abuts against the extension section N, a spring 142 sleeved on the rod body of the push rod 141, and an adjusting member 143 arranged on the outside of the push rod 141.

[0069] In one embodiment provided in the present application, the push rod 141 presses the extension section N into the tube, causing one side of the pressing plate 1223 to come into contact with the sleeve 32 .

[0070] In one embodiment provided in the present application, the end of the stop rod 141 is a screw rod;

[0071] The adjusting member 143 includes a snap ring 1431 protruding from the sides of the baffle 1112 and the arc plate 1113 , a docking ring 1432 matching the snap ring 1431 , and a nut 1433 slidably connected to the end of the docking ring 1432 .

[0072] In this embodiment, one end of the push rod 141 is in contact with the extension section N, and the other end is controlled by the adjusting member 143 for axial displacement; the spring 142 is sleeved on the rod body of the push rod 141 to provide a pre-tightening force to enhance the clamping stability of the spring plate 122; the adjusting member 143 is arranged on the outside of the push rod 141 to adjust the extension length of the push rod 141, thereby controlling the opening and closing degree of the spring plate 122.

[0073] Preferably, the end of the push rod 141 is designed as a screw structure, and its threaded section can be screwed into the nut 1433 of the adjusting member 143 to achieve axial locking; the other end of the push rod 141 is designed as a round head near the extension section N, which contacts the outside of the extension section N, and pushes the pressing plate 1223 of the spring plate 122 outward through pressure transmission, thereby enhancing its fit with the sleeve 32; the spring 142 is sleeved on the rod body of the push rod 141, located between the adjusting member 143 and the extension section N, providing a constant preload.

[0074] Preferably, the material of the push rod 141 is preferably 45# steel or stainless steel SUS304, and the surface is carburized and quenched (HRC≥55) to improve wear resistance and fatigue resistance.

[0075] Preferably, the snap ring 1431 is respectively protruded from the sides of the baffle 1112 and the arc plate 1113 to form a fixed support structure; the docking ring 1432 cooperates with the snap ring 1431, and the docking ring 1432 and the snap ring 1431 are fixedly connected by rotation, so that when they are clamped together, the nut 1433 is slidably connected to the end of the docking ring 1432, and cooperates with the screw section of the push rod 141 through a thread to achieve position locking; after the docking ring 1432 and the snap ring 1431 are rotated and misaligned, a sliding guide channel is formed to allow the push rod 141 to move axially.

[0076] When the spring plate 122 is elastically deformed due to the change in the diameter of the cable tube 31, the displacement of the extension section N will be transmitted to the adjustment member 143 through the push rod 141; by rotating the nut 1433, the extension length of the push rod 141 can be adjusted, thereby changing the compression amount of the spring 142, and then controlling the clamping force of the spring plate 122.

[0077] Another purpose of adjusting the extension length of the push rod 141 by rotating the nut 1433 is that since the push rod 141 is facing the middle position of the extension section N, when the push rod 141 squeezes the extension section N inward, the pressing plate 1223 protruding on the inner side of the end of the extension section N will be tilted due to uneven force, and can be pressed on the outside of the sleeve 32 with a larger diameter, thereby clamping the two sets of cable tubes 31 while pressing and fixing the sleeve 32 to prevent displacement during welding.

[0078] Finally, it should be pointed out that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
