Description

Technical Field

[0001] The invention relates to the technical field of repairing cracks on a cable outer sheath, in particular to a cable outer sheath repairing device and method. Background Art

[0002] When the cable is being laid, improper operation may cause cracks 2 on the outer sheath 1 of the cable, such as Figure 1 As shown, the existence of the crack seriously affects the normal operation of the cable. For this reason, after the crack 2 is generated on the outer sheath 1 of the cable, the worker needs to repair the crack.

[0003] The specific repair method is: the worker first takes out the first semicircular template and the second semicircular template, snaps the cavity of the first semicircular template onto the top surface of the cable outer sheath 1, and then snaps the cavity of the second semicircular template onto the bottom surface of the cable outer sheath 1. At this time, a closed cavity is formed between the inner walls of the two template cavities and the outer surface of the cable outer sheath 1, and the crack 2 on the outer sheath 1 is just in the closed cavity; then the worker puts a certain amount of molten glue into the filling port on the first semicircular template. The material of the molten glue is the same as that of the outer sheath 1. The molten glue fills the closed cavity to form a wrapping layer, and the wrapping layer 3 wraps the crack 2 on the outer sheath 1, thereby realizing the repair of the crack 2 on the cable outer sheath 1. Figure 2 As shown; after repair, the first semicircular mold and the second semicircular mold are removed from the outer sheath of the cable.

[0004] However, although the first semicircular template and the second semicircular template can be used to repair the crack 2 of the outer sheath 1 on the cable, the following technical defects still exist in the technology:

[0005] I. There is no obstruction on the left and right sides of the wrapping layer 3. When the wrapping layer 3 is subjected to external force along the length direction of the outer sheath 1, the wrapping layer 3 is easily loosened from the outer sheath 1 of the cable, thereby causing the repaired crack 2 to be exposed again. Therefore, the repair method using the first semicircular template and the second semicircular template has a technical defect of low repair quality.

[0006] II. Since the length of the first semicircular template and the second semicircular template is limited, when the length of the crack 2 is greater than the length of the template, the long crack 2 cannot be repaired, so you can only go to the warehouse to select a template of another specification to repair the long crack 2; and before each repair, you need to manually select a template that is suitable for the length of the crack 2, and templates of different specifications are mixed together, which undoubtedly delays the repair time, thereby greatly improving the repair efficiency of the crack 2.

[0007] Therefore, there is an urgent need for a repair device and method that can greatly improve the quality of repairing cracks on the cable outer sheath and greatly improve the efficiency of repairing cracks on the cable outer sheath. Summary of the invention

[0018] The repair device also includes a controller, which is connected to the first clamping cylinder, the second clamping cylinder, the lifting cylinder, the first vacuum pump, and the second vacuum pump.

[0019] A method for repairing an outer sheath of a cable comprises the following steps:

[0020] S1. The worker pulls the head end of the outer sheath of the cable to be repaired to the right, and then passes the head end of the outer sheath through the through slot of the left clamping mechanism and the through slot of the right clamping mechanism from left to right. When the worker observes that the crack on the outer sheath of the cable is directly below the first semicircular cylinder and the second semicircular cylinder of the upper repair mechanism, the worker keeps the outer sheath motionless;

[0021] S2, control the piston rods of the first clamping cylinder and the second clamping cylinder of the left clamping mechanism to extend, the first clamping cylinder drives the V-shaped clamping block to move downward, and the second clamping cylinder drives the V-shaped clamping block to move upward. When the piston rods of the first clamping cylinder and the second clamping cylinder are fully extended, the left end of the outer sheath of the cable is just fixed between the V-shaped grooves of the two V-shaped clamping blocks;

[0022] Similarly, the piston rods of the first clamping cylinder and the second clamping cylinder of the right clamping mechanism are extended, and the right end of the outer sheath of the cable is just fixed between the V-shaped grooves of the two V-shaped clamping blocks;

[0023] S3, the worker takes out a semicircular clamp ring A and a semicircular clamp ring B, the outer diameter of the semicircular clamp ring B is larger than the outer diameter of the semicircular clamp ring A; the worker inserts the semicircular clamp ring A into the semicircular hole of the first semicircular clamp seat of the upper repair mechanism, and ensures that the opening of the semicircular clamp ring A faces downward, and then starts the first vacuum pump of the upper repair mechanism. Under negative pressure, the semicircular clamp ring A is adsorbed and fixed in the first semicircular clamp seat;

[0024] The worker inserts the semicircular clamp ring B into the semicircular hole of the second semicircular clamp seat of the upper repair mechanism, and ensures that the opening of the semicircular clamp ring B faces downward, and then starts the second vacuum pump of the upper repair mechanism. Under negative pressure, the semicircular clamp ring B is adsorbed and fixed in the second semicircular clamp seat;

[0025] S4, the worker repeats the operation of step S3 once, so as to absorb and fix the semicircular clamping ring A and the semicircular clamping ring B into the first semicircular clamping seat and the second semicircular clamping seat of the lower repairing mechanism respectively;

[0026] S5. The piston rod of the lifting cylinder of the control upper repair mechanism extends downward, and the piston rod drives the lifting plate to move downward, and the lifting plate drives the first vacuum pump, the second vacuum pump, the first semicircular clamping seat, the driving motor, the guide seat and the second semicircular clamping seat to move downward synchronously, wherein the first semicircular clamping seat also drives the semicircular clamping ring A and the first semicircular cylinder to move downward synchronously, and at the same time, the second semicircular clamping seat drives the semicircular clamping ring B and the second semicircular cylinder to move downward synchronously; when the piston rod of the lifting cylinder is fully extended, the semicircular clamping ring A and the semicircular clamping ring B are both buckled on the top surface of the outer sheath of the cable, and the semicircular clamping ring A and the semicircular clamping ring B are respectively located on both sides of the crack;

[0027] S6, controlling the piston rod of the lifting cylinder of the lower repair mechanism to extend upward, so that the semicircular clamping ring A and the semicircular clamping ring B of the lower repair mechanism are both buckled on the bottom surface of the outer sheath of the cable, and the semicircular clamping ring A and the semicircular clamping ring B are respectively located on both sides of the crack;

[0028] S7. The worker puts a certain amount of molten glue into the filling port. The material of the molten glue is the same as that of the outer sheath. The molten glue fills the closed cavity to form a wrapping layer. The wrapping layer wraps the cracks on the outer sheath, thereby repairing the cracks on the cable outer sheath.

[0029] S8, taking away the repaired cable: control the piston rods of the first clamping cylinder and the second clamping cylinder of the left clamping mechanism and the right clamping mechanism to retract, and the V-shaped clamp block is separated from the outer sheath of the cable; then control the first vacuum pump and the second vacuum pump of the upper repair mechanism and the lower repair mechanism to be turned off; then control the piston rods of the lifting cylinders of the upper repair mechanism and the lower repair mechanism to retract, so that the two first semicircular cylinders are separated from the wrapping layer, and the two second semicircular cylinders are separated from the wrapping layer. After separation, the worker takes away the repaired outer sheath of the cable;

[0030] S9. Repeat steps S1 to S8 for multiple times to repair the outer sheaths of multiple cables.

[0031] The present invention has the following advantages:

[0032] I. An upper repairing mechanism and a lower repairing mechanism for repairing cracks on the cable outer sheath are arranged between the vertical plate of the left clamping mechanism and the vertical plate of the right clamping mechanism of the present invention. When the crack on the outer sheath is long, the driving motors of the upper repairing mechanism and the lower repairing mechanism can be controlled to start, and the driving motor drives the gear to rotate, the gear drives the rack to move right, the rack drives the guide rod to move right, the guide rod drives the second semicircular holder to move right, the second semicircular holder drives the second semicircular cylinder to move right, and the second semicircular cylinder moves right relative to the stationary first semicircular cylinder, so that the first semicircular cylinder and the second semicircular cylinder are suitable for the length of long cracks, and there is no need for workers to select templates suitable for the length of the cracks, thereby greatly improving the repair efficiency of the cracks on the cable outer sheath.

[0033] II. Since two semicircular clamping rings A are clamped at the left end of the cable outer sheath, and two semicircular clamping rings B are clamped at the right end of the cable outer sheath, and the wrapping layer is axially restricted between the semicircular clamping ring A and the semicircular clamping ring B, when the wrapping layer is subjected to external force along the length direction of the outer sheath, the wrapping layer will not loosen from the outer sheath of the cable, thereby avoiding the repaired cracks from being exposed again. It can be seen that compared with the repair method using the first semicircular template and the second semicircular template, the repair device greatly improves the repair quality of cracks on the cable outer sheath.

[0070] A method for repairing an outer sheath of a cable comprises the following steps:

[0071] S1. Workers will Figure 1The head end of the outer sheath 1 of the cable to be repaired is pulled out to the right, and then the head end of the outer sheath 1 passes through the through slot 8 of the left clamping mechanism 5 and the through slot 8 of the right clamping mechanism 6 from left to right in sequence, as shown in FIG. Fig.15 As shown, when the crack 2 on the cable outer sheath 1 is observed to be directly below the first semicircular cylinder 18 and the second semicircular cylinder 28 of the upper repair mechanism 12, the worker keeps the outer sheath 1 still;

[0072] S2, control the piston rods of the first clamping cylinder 9 and the second clamping cylinder 10 of the left clamping mechanism 5 to extend, the first clamping cylinder 9 drives the V-shaped clamping block 11 to move downward, and the second clamping cylinder 10 drives the V-shaped clamping block 11 to move upward. When the piston rods of the first clamping cylinder 9 and the second clamping cylinder 10 are fully extended, the left end of the outer sheath 1 of the cable is just fixed between the V-shaped grooves of the two V-shaped clamping blocks 11, as shown in FIG. Fig.16 As shown;

[0073] Similarly, the piston rods of the first clamping cylinder 9 and the second clamping cylinder 10 of the right clamping mechanism 6 are extended, and the right end of the outer sheath 1 of the cable is just fixed between the V-shaped grooves of the two V-shaped clamping blocks 11, as shown in FIG. Fig.16 As shown;

[0074] S3, the worker takes out a Fig.17 The semicircular retaining ring A33 shown and a Fig.18 The semicircular snap ring B34 shown in the figure has an outer diameter greater than that of the semicircular snap ring A33. The worker inserts the semicircular snap ring A33 into the semicircular hole 19 of the first semicircular holder 17 of the upper repair mechanism 12, and ensures that the opening of the semicircular snap ring A33 faces downward, and then starts the first vacuum pump 21 of the upper repair mechanism 12. Under negative pressure, the semicircular snap ring A33 is adsorbed and fixed in the first semicircular holder 17, as shown in FIG. Fig.19 As shown;

[0075] The worker inserts the semicircular clamp ring B34 into the semicircular hole 19 of the second semicircular clamp seat 27 of the upper repair mechanism 12, and ensures that the opening of the semicircular clamp ring B34 faces downward, and then starts the second vacuum pump 30 of the upper repair mechanism 12. Under negative pressure, the semicircular clamp ring B34 is adsorbed and fixed in the second semicircular clamp seat 27, as shown in FIG. Fig.19 As shown;

[0076] S4, the worker repeats the operation of step S3 once, so as to fix the semicircular clamping ring A33 and the semicircular clamping ring B34 in the first semicircular clamping seat 17 and the second semicircular clamping seat 27 of the lower repair mechanism 13 by absorption respectively;

[0077] S5. The piston rod of the lifting cylinder 14 of the upper repair mechanism 12 is controlled to extend downward, and the piston rod drives the lifting plate 15 to move downward. The lifting plate 15 drives the first vacuum pump 21, the second vacuum pump 30, the first semicircular holder 17, the drive motor 23, the guide seat 22 and the second semicircular holder 27 to move downward synchronously, wherein the first semicircular holder 17 also drives the semicircular clamping ring A33 and the first semicircular cylinder 18 to move downward synchronously, and at the same time, the second semicircular holder 27 drives the semicircular clamping ring B34 and the second semicircular cylinder 28 to move downward synchronously; when the piston rod of the lifting cylinder 14 is fully extended, the semicircular clamping ring A33 and the semicircular clamping ring B34 are both buckled on the top surface of the outer sheath 1 of the cable, as shown in FIG. Figure 20~Figure 22 As shown, the semicircular snap ring A33 and the semicircular snap ring B34 are respectively located on both sides of the crack 2;

[0078] S6, controlling the piston rod of the lifting cylinder 14 of the lower repair mechanism 13 to extend upward, so that the semicircular clamping ring A33 and the semicircular clamping ring B34 of the lower repair mechanism 13 are both buckled on the bottom surface of the outer sheath 1 of the cable, and the semicircular clamping ring A33 and the semicircular clamping ring B34 are respectively located on both sides of the crack 2;

[0079] S7, the worker puts a certain amount of molten glue into the filling port 31. The material of the molten glue is the same as that of the outer sheath 1. The molten glue fills the closed cavity to form a wrapping layer 3. Fig.23 As shown, the wrapping layer 3 wraps the crack 2 on the outer sheath 1, thereby repairing the crack 2 on the cable outer sheath 1;

[0080] S8. Removal of the repaired cable: Control the piston rods of the first clamping cylinder 9 and the second clamping cylinder 10 of the left clamping mechanism 5 and the right clamping mechanism 6 to retract, and the V-shaped clamping block 11 is separated from the outer sheath 1 of the cable; then control the first vacuum pump 21 and the second vacuum pump 30 of the upper repair mechanism 12 and the lower repair mechanism 13 to be turned off; then control the piston rods of the lifting cylinder 14 of the upper repair mechanism 12 and the lower repair mechanism 13 to retract, so that the two first semicircular cylinders 18 are separated from the wrapping layer 3, and the two second semicircular cylinders 28 are separated from the wrapping layer 3. After separation, the worker takes away the repaired outer sheath 1 of the cable. The structure of the repaired outer sheath 1 of the cable is as shown in FIG. Fig.24 As shown;

[0081] S9. Repeat steps S1 to S8 for multiple times to repair the outer sheaths 1 of multiple cables.

[0082] Among them, it can be seen from step S8 that since two semicircular clamping rings A33 are clamped at the left end of the cable outer sheath 1, and two semicircular clamping rings B34 are clamped at the right end of the cable outer sheath 1, and the wrapping layer 3 is axially restricted between the semicircular clamping ring A33 and the semicircular clamping ring B34, therefore, when the wrapping layer 3 is subjected to external force along the length direction of the outer sheath 1, the wrapping layer 3 will not loosen from the outer sheath 1 of the cable, thereby avoiding the repaired crack 2 from being exposed again. It can be seen that compared with the repair method using the first semicircular template and the second semicircular template, the repair device greatly improves the repair quality of the cracks on the cable outer sheath 1.

[0083] When the crack 2 on the outer sheath 1 is long, the driving motor 23 of the upper repair mechanism 12 and the lower repair mechanism 13 can be controlled to start, the driving motor 23 drives the gear 24 to rotate, the gear 24 drives the rack 26 to move rightward, the rack 26 drives the guide rod 25 to move rightward, the guide rod 25 drives the second semicircular holder 27 to move rightward, the second semicircular holder 27 drives the second semicircular cylinder 28 to move rightward, the second semicircular cylinder 28 moves rightward relative to the stationary first semicircular cylinder 18, so that the first semicircular cylinder 18 and the second semicircular cylinder 28 are suitable for the length of the long crack 2, and then repeat the operation of steps S1 to S8 to complete the repair of the long crack 2 on the cable outer sheath 1. It can be seen that compared with the method of using two semicircular templates for repair, the present repair device does not require workers to select templates suitable for the length of the crack 2, thereby greatly improving the repair efficiency of the crack 2 on the cable outer sheath 1.
