Description
Technical Field
[0001] The invention relates to the technical field of heating cable fusion joints, in particular to a heating device and method for uniformly heating cable fusion joints with anti-deformation properties. Background Art
[0002] Cable injection welding joint technology is a new type of power cable connection technology. Cable injection welding joint technology mainly solves the interface caused by different insulation materials during the connection of two cables, thereby basically restoring the physical structure and electrical performance of the original cable.
[0003] The principle of the cable injection welding joint technology to connect two cables 1 together is: workers first form a cable welding joint 2 between two cables 1 with an outer diameter of 6~8cm, such as Figure 1~Figure 2 As shown; then the two cables 1 are heated simultaneously. When the cable 1 is heated, the cable 1 transfers the heat thereon to the cable fusion joint 2. When the cable fusion joint 2 is heated, the cable fusion joint 2 and the two cables 1 are fused into one, thereby forming a complete and usable cable line.
[0004] Among them, the heating process of the cable fusion joint 2 is an important part of the whole docking process. A workshop adopts the following method: Figure 3 The heating device shown is used to heat the cable fusion joint 2, and the heating device includes two machines 4 fixed on the bottom plate 3, and lower heating plates 5 are fixed on the top surfaces of the two machines 4, and brackets 6 are arranged directly above the two lower heating plates 5. Cylinders 7 are fixed on the top surfaces of the two brackets 6, and the piston rod of the cylinder 7 passes through the bracket 6, and an upper heating plate 8 is fixed on the extending end, and the upper heating plate 8 is located directly above the lower heating plate 5.
[0005] The method by which the heating device heats the cable fusion joint 2 is: S1. The worker places the cable 1 on the left side flat on the lower heating plate 5 on the left side, and at the same time, places the cable 1 on the right side flat on the lower heating plate 5 on the right side, as shown in FIG. Figure 4 As shown; S2, control the piston rods of the two cylinders 7 to extend downward, and the piston rods drive the upper heating plate 8 to move downward. When the upper heating plate 8 contacts the top surface of the cable 1, Figure 5 As shown, the control cylinder 7 is closed; S3, the upper heating plate 8 and the lower heating plate 5 are powered on, and heat is generated on both the upper heating plate 8 and the lower heating plate 5. The upper heating plate 8 heats the top surface of the cable 1, and at the same time, the lower heating plate 5 heats the bottom surface of the cable 1; when the cable 1 is heated, the cable 1 transfers the heat to the cable fusion joint 2. When the cable fusion joint 2 is heated, the cable fusion joint 2 and the two cables 1 are fused into one, thereby forming a complete and usable cable line; S4. Removal of the cables: The worker retracts the piston rods of the two cylinders 7 upward, and the piston rods drive the upper heating plate 8 to move upward. When the upper heating plate 8 is reset, the worker removes the formed cables from the two lower heating plates 5.
[0006] However, although this heating device can heat the cable fusion joint 2, it still has the following technical defects: I. There is an arc-shaped protrusion 9 on the top surface of the cable 1, which blocks the downward movement of the upper heating plate 8, so that the upper heating plate 8 does not heat the materials on the left and right sides of the arc-shaped protrusion 9, causing the cable 1 to be heated unevenly, and then causing the cable fusion joint 2 to be heated unevenly, and then causing the cable fusion joint 2 to not be firmly fused with the cable 1, thereby reducing the fusion quality of the cable fusion joint 2 and the cable 1; In addition, there is a concave groove 10 on the bottom surface of the cable 1, and the lower heating plate 5 can only heat the materials on the left and right sides of the concave groove 10, but cannot heat the bottom of the concave groove 10, which also causes uneven heating of the cable 1, and then causes uneven heating of the cable fusion joint 2, and then causes the cable fusion joint 2 to not be firmly fused with the cable 1, further reducing the fusion quality of the cable fusion joint 2 and the cable 1; II. When the cable fusion joint 2 is heated, its outer surface expands and deforms outwards [while the process requires that the cable fusion joint 2 should not deform after heating], thereby reducing the fusion quality of the cable fusion joint 2 and the cable 1.
[0007] Therefore, there is an urgent need for a heating device and method that can evenly heat two cables and greatly improve the fusion quality of the cable fusion joint and the cable. Summary of the invention

[0010] The left heating mechanism and the right heating mechanism are arranged symmetrically with respect to the positioning mechanism.
[0011] The front heating mold and the rear heating mold of the right heating mechanism are arranged symmetrically front and back with respect to the positioning mechanism.

[0017] A method for heating a cable fusion joint with anti-deformation uniform heating, comprising the following steps: S1. The worker inserts the cable fusion joint into the lower arc groove of the positioning seat of the positioning mechanism from top to bottom. Since the lower arc groove matches the outer contour of the lower half of the cable fusion joint, the cable fusion joint is positioned. At this time, the cable on the left side of the cable fusion joint is just between the two heating molds of the left heating mechanism, and the cable on the right side of the cable fusion joint is just between the two heating molds of the right heating mechanism; S2.

The worker turns on the power supply, and the power supply energizes each heating rod in the semicircular heat-conducting cylinder. When the heating rod is energized, heat is generated on it, and the heat is transferred to the semicircular heat-conducting cylinder.

DETAILED DESCRIPTION
[0020] The present invention is further described below in conjunction with the accompanying drawings, and the protection scope of the present invention is not limited to the following: like Figure 6~Figure 16 As shown, a heating device for uniformly heating a cable fusion joint with anti-deformation comprises a backing plate 11, on which a positioning mechanism 12 for positioning the cable fusion joint 2 and a clamping mechanism 13 for clamping the cable fusion joint 2 are arranged; The positioning mechanism 12 includes a vertical plate 14 fixed on the backing plate 11 and a positioning seat 15 fixed on the top surface of the vertical plate 14.

The upper arc groove 20 is located directly above the lower arc groove 16, and the upper arc groove 20 matches the outer contour of the upper half of the cable fusion joint 2.
[0022] The pad 11 is also provided with a left heating mechanism 21 and a right heating mechanism 22 for uniformly heating the two cables 1 respectively. The left heating mechanism 21 and the right heating mechanism 22 are symmetrically arranged with respect to the positioning mechanism 12. The left heating mechanism 21 and the right heating mechanism 22 are respectively located on the left and right sides of the positioning mechanism 12. The right heating mechanism 22 includes a column 23 fixed on the pad 11, and a double-acting cylinder 24 fixed on the top surface of the column 23 and longitudinally arranged. A connecting frame 25 is fixed on the two piston rods of the double-acting cylinder 24, and a heating mold 26 is welded on the left end of the two connecting frames 25; the front heating mold 26 and the rear heating mold 26 of the right heating mechanism 22 are symmetrically arranged with respect to the positioning mechanism 12.
[0023] The heating mold 26 located at the rear side includes a semicircular heat-conducting tube 27 with an opening facing forward. The right end of the semicircular heat-conducting tube 27 is fixedly arranged on the right end of the connecting frame 25. A plurality of heating rods 28 arranged at intervals are fixedly arranged in the semicircular heat-conducting tube 27 along its circumference. The plurality of heating rods 28 in the semicircular heat-conducting tube 27 are evenly distributed in the semicircular heat-conducting tube 27. The joints of each heating rod 28 are connected to a power supply. A heat-conducting column 30 arranged horizontally at intervals is arranged between each adjacent heating rod 28. The spacing between each adjacent two heat-conducting columns 30 is equal. The heat-conducting column 30 radially slides through the semicircular heat-conducting tube 27. The inner end of the heat-conducting column 30 extends into the opening of the semicircular heat-conducting tube 27. A round head 31 is fixedly arranged on the outer end of the heat-conducting column 30. A spring 32 is sleeved on the heat-conducting column 30. One end of the spring 32 is fixedly arranged on the outer cylindrical surface of the semicircular heat-conducting tube 27, and the other end is fixedly arranged on the round head 31.
[0024] One end of the connecting frame 25 is welded to the working end of the piston rod of the double-acting oil cylinder 24, and the other end is welded to the right end of the semicircular heat-conducting cylinder 27. An axial hole 33 arranged along the axial direction of the semicircular heat-conducting cylinder 27 is provided in the semicircular heat-conducting cylinder 27, and the heating rod 28 is embedded in the axial hole 33. A radial hole arranged radially is provided on the cylindrical surface of the semicircular heat-conducting cylinder 27, and the diameter of the radial hole is equal to that of the heat-conducting column 30, and the heat-conducting column 30 is slidably installed in the radial hole.
[0025] The heating device also includes a controller, which is electrically connected to the vertical cylinder 18 and the double-acting cylinder 24 via a signal line. Workers can extend or retract the piston rods of the vertical cylinder 18 and the double-acting cylinder 24 through the controller, which facilitates the workers' operation and has the characteristic of a high degree of automation.
[0026] A method for heating a cable fusion joint with anti-deformation uniform heating, comprising the following steps: S1. The worker inserts the cable fusion joint 2 from top to bottom into the lower arc groove 16 of the positioning seat 15 of the positioning mechanism 12. Since the lower arc groove 16 matches the outer contour of the lower half of the cable fusion joint 2, the cable fusion joint 2 is positioned. Fig.17 As shown, at this time, the cable 1 located on the left side of the cable fusion joint 2 is just between the two heating dies 26 of the left heating mechanism 21, and the cable 1 located on the right side of the cable fusion joint 2 is just between the two heating dies 26 of the right heating mechanism 22; S2, control the piston rod of the vertical oil cylinder 18 of the clamping mechanism 13 to extend downward, the piston rod drives the clamping seat 19 to move downward, and the clamping seat 19 drives the upper arc groove 20 therein to move synchronously toward the cable fusion joint 2. When the piston rod of the vertical oil cylinder 18 is fully extended, the clamping seat 19 and the positioning seat 15 are closed. Fig.18 As shown, at this time, the cable fusion joint 2 is just limited between the upper arc groove 20 and the lower arc groove 16; S3: heating the left cable 1 and the right cable 1 simultaneously. The specific operation steps are as follows: S31, control the two piston rods of the double-acting oil cylinder 24 of the left heating mechanism 21 and the right heating mechanism 22 to retract at the same time, and the two piston rods respectively drive the connecting frame 25 connected thereto to move toward the direction of the cable 1, and the connecting frame 25 drives the semicircular heat-conducting cylinder 27 of the heating mold 26 to move toward the direction of the cable 1, such as Fig.19 As shown, the semicircular heat-conducting cylinder 27 drives each heat-conducting column 30 and spring 32 thereon to move synchronously toward the cable 1; When the two heating molds 26 are closed, the two semicircular heat-conducting cylinders 27 hold the cable 1. Since each heat-conducting column 30 can float radially under the elastic force of the spring 32, the inner end of each heat-conducting column 30 can adaptively contact the outer surface of the cable 1. S32, the worker turns on the power supply, and the power supply energizes each heating rod 28 in the semicircular heat-conducting cylinder 27. When the heating rod 28 is energized, heat is generated on it, and the heat is transferred to the semicircular heat-conducting cylinder 27. The semicircular heat-conducting cylinder 27 then transfers the heat to each heat-conducting column 30 thereon. The heat-conducting column 30 transfers the heat to the surface of the cable 1, and the cable 1 transfers the heat on it to the cable fusion joint 2. When the cable fusion joint 2 is heated, the cable fusion joint 2 gradually merges with the two cables 1 into one. After heating for a period of time, the power supply is turned off, thereby finally forming a complete and usable cable line; Among them, it can be known from steps S31~S32 that since the inner end of each heat-conducting column 30 can adaptively contact the outer surface of the cable 1, the inner end of a part of the heat-conducting column 30 not only contacts the arc-shaped protrusion 9 of the cable 1, but also contacts the left and right side materials of the arc-shaped protrusion 9; at the same time, the inner end of another part of the heat-conducting column 30 not only contacts the bottom of the concave groove 10, but also contacts the left and right side materials of the concave groove 10. Therefore, when the heating rod 28 is energized, the heat-conducting column 30 in contact with the arc-shaped protrusion 9 can transfer heat to the arc-shaped protrusion 9, and at the same time, the heat-conducting column 30 in contact with the bottom of the concave groove 10 can transfer heat to the bottom of the concave groove 10, thereby ensuring that the two cables 1 are evenly heated, and then ensuring that the cable fusion joint 2 is evenly heated, so that the cable fusion joint 2 can be firmly fused with the cable 1, compared to the following Figure 3~Figure 5 The heating device shown greatly improves the fusion quality of the cable fusion joint 2 and the cable 1.
[0027] S4. Remove the cable. The specific steps are as follows: S41, control the two piston rods of the double-acting oil cylinder 24 of the left heating mechanism 21 and the right heating mechanism 22 to extend simultaneously, the two piston rods respectively drive the connecting frame 25 connected thereto to move away from the cable 1, the connecting frame 25 drives the semicircular heat-conducting cylinder 27 of the heating mold 26 to move away from the cable 1, and the semicircular heat-conducting cylinder 27 drives the various heat-conducting columns 30 and springs 32 thereon to move synchronously away from the cable 1; S42, the piston rod of the vertical oil cylinder 18 of the clamping mechanism 13 is controlled to retract upward, and the piston rod drives the clamping seat 19 to move upward, and then the worker removes the cable fusion joint 2 of the cable from the lower arc groove 16 of the positioning seat 15; S5. By repeating the operations of steps S1 to S4, the cable 1 can be heated continuously, and a plurality of complete and usable cables can be formed.
[0028] Among them, it can be seen from steps S1 to S2 that since the cable fusion joint 2 is always limited between the upper arc groove 20 and the lower arc groove 16, when the cable fusion joint 2 is heated, the expansion and deformation are limited, thereby playing a good role in protecting the cable fusion joint 2. It can be seen that the heating device is compared with the heating device of the present invention. Figure 3~Figure 5 The heating device shown further improves the fusion quality of the cable fusion joint 2 and the cable 1.
[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.

At this time, the cable (1) located on the left side of the cable fusion joint (2) is just located between the two heating molds (26) of the left heating mechanism (21), and the cable (1) located on the right side of the cable fusion joint (2) is just located between the two heating molds (26) of the right heating mechanism (22); S2, controlling the piston rod of the vertical oil cylinder (18) of the clamping mechanism (13) to extend downward, the piston rod drives the clamping seat (19) to move downward, and the clamping seat (19) drives the upper arc groove (20) therein to move synchronously toward the cable fusion joint (2). When the piston rod of the vertical oil cylinder (18) is fully extended, the clamping seat (19) and the positioning seat (15) are closed, and at this time, the cable fusion joint (2) is just confined between the upper arc groove (20) and the lower arc groove (16); S3: heating the left cable (1) and the right cable (1) simultaneously. The specific operation steps are as follows: S31, controlling the two piston rods of the double-acting oil cylinder (24) of the left heating mechanism (21) and the right heating mechanism (22) to retract simultaneously, the two piston rods respectively drive the connecting frame (25) connected thereto to move toward the direction of the cable (1), the connecting frame (25) drives the semicircular heat-conducting cylinder (27) of the heating mold (26) to move toward the direction of the cable (1), and the semicircular heat-conducting cylinder (27) drives the various heat-conducting columns (30) and springs (32) thereon to move synchronously toward the direction of the cable (1); When the two heating molds (26) are closed, the two semicircular heat-conducting cylinders (27) hold the cable (1), and because each heat-conducting column (30) can float radially under the elastic force of the spring (32), the inner end of each heat-conducting column (30) can adaptively contact the outer surface of the cable (1); S32, the worker turns on the power supply, and the power supply energizes each heating rod (28) in the semicircular heat-conducting cylinder (27). When the heating rod (28) is energized, heat is generated on it, and the heat is transferred to the semicircular heat-conducting cylinder (27). The semicircular heat-conducting cylinder (27) then transfers the heat to each heat-conducting column (30) thereon. The heat-conducting column (30) transfers the heat to the surface of the cable (1). The cable (1) transfers the heat on it to the cable fusion joint (2). When the cable fusion joint (2) is heated, the cable fusion joint (2) gradually fuses with the two cables (1) into one. After heating for a period of time, the power supply is turned off, thereby finally forming a complete and usable cable line; S4. Remove the cable. The specific steps are as follows: S41, controlling the two piston rods of the double-acting oil cylinder (24) of the left heating mechanism (21) and the right heating mechanism (22) to extend simultaneously, the two piston rods respectively drive the connecting frame (25) connected thereto to move in a direction away from the cable (1), the connecting frame (25) drives the semicircular heat-conducting cylinder (27) of the heating mold (26) to move in a direction away from the cable (1), and the semicircular heat-conducting cylinder (27) drives the various heat-conducting columns (30) and springs (32) thereon to move synchronously in a direction away from the cable (1); S42, the piston rod of the vertical oil cylinder (18) of the clamping mechanism (13) is controlled to retract upward, and the piston rod drives the clamping seat (19) to move upward, and then the worker removes the cable fusion joint (2) of the cable line from the lower arc groove (16) of the positioning seat (15); S5. By repeating the operations of steps S1 to S4, the cable (1) can be continuously heated, and a plurality of complete and usable cables can be formed.
