Description

Technical Field

[0001] The invention relates to the technical field of defective cable recycling, and in particular to a device for recycling defective insulation and fireproof cables. Background Art

[0002] Urban underground engineering pipelines refer to various power pipelines, heating pipelines, water pipelines, etc. buried in underground pipeline corridors.

[0003] Among them, after the power pipeline has been used for a long time, some cables will be damaged. In order to ensure the stable power supply of the power pipeline, it is necessary to replace the damaged cable line in time. The existing replacement method is generally to cut off the damaged cable section, pull the cable out of the buckle, and then replace it with a new cable. However, the buckle and the insulation skin will be stuck together after being used for a long time. When the cable is pulled out from the buckle after being cut off, due to the adhesion between the buckle and the insulation skin, the forced extraction method will not only cause serious damage to the insulation skin, but also cause a large amount of insulation skin to remain on the cable buckle. Before installing the new cable on the buckle later, the insulation skin needs to be removed, otherwise the new cable will be difficult to install normally, and the operation is complicated and cumbersome.

[0004] Therefore, the prior art generally adopts a stripping method to solve the problem by first stripping off the insulation and recycling the wire core at the same time. However, the existing insulation stripping method can easily scratch the wire core, affecting the recycling and reuse of the wire core. Summary of the invention

[0005] In order to overcome the disadvantages of the prior art that the wire core is easily scratched, which affects the recovery and reuse of the wire core, the present invention provides a device for recovering and recycling defective insulated fireproof cables.

[0007] Optionally, it also includes a multi-section push rod and a disc; a plurality of multi-section push rods are arranged on the left side of the lower box body; and a disc is arranged on the telescopic part of each multi-section push rod.

[0008] Optionally, it also includes a pneumatic push rod and a telescopic support plate; a plurality of pneumatic push rods are arranged on the rear side of the lower box body; and the telescopic parts of all the pneumatic push rods are fixedly connected to a telescopic support plate.

[0009] Optionally, a guide roller is also included; the lower box is equipped with the guide roller, and the guide roller is located below the wire core.

[0010] Optionally, an anti-adhesion unit is also included, which includes a second electric push rod and an arc-shaped pressure strip; the second electric push rod is installed on the upper surface of the lower box; and the telescopic part of the second electric push rod is fixedly connected to the arc-shaped pressure strip.

[0011] Optionally, the anti-adhesion unit also includes a third electric push rod, a half ring, an air injection pipe and a ventilation plate; a third electric push rod is provided on each facing surface of the two boxes; a ventilation plate is provided on the telescopic part of each third electric push rod; each ventilation plate is provided with a half ring, and the two half rings are combined to form a circular ring, and the half ring is arranged as a hollow structure; the ventilation plate is connected to the air injection pipe, and the air injection pipe is arranged as a telescopic structure.

[0012] Optionally, an anti-oxidation unit is also included, which includes a hollow cooling plate, an air pump and a ventilation pipe; the upper box is equipped with a hollow cooling plate, and the hollow cooling plate is connected to the air injection pipe; the hollow cooling plate is provided with an air pump; the hollow cooling plate is connected to the ventilation pipe, and the ventilation pipe is connected to the lower box; the connecting plate is provided with an air outlet, and the air outlet is inclined toward the cable.

[0013] Optionally, the anti-oxidation unit also includes a support plate and a collection box; the ventilation plate is connected to two support plates distributed on the left and right; the support plate is arranged to be a hollow structure; the two support plates are commonly connected to the cutter; an air outlet slot is arranged at the front of the support plate; the two support plates are commonly fixed with a collection box, and the collection box is in contact with the cutter, and the collection box is communicated with the support plate.

[0014] Optionally, a blowing slot is provided on the rear side of each half ring.

[0015] Optionally, the two half rings are combined to form a conical ring that is larger at the front and smaller at the back.

[0016] The beneficial effect of the present invention is that the present invention pulls up the two wire cores with a gap at the top and pulls down the other wire cores, so that the insulation skin on the upper part of the cable is tilted upward, and there is no wire core below the middle part of the upward tilted insulation skin, but is in a vacant state. At this time, the middle part of the upward tilted insulation skin is cut by a cutter, so that the insulation skin can be smoothly peeled off, which is not only convenient for cutting, but also can avoid damaging the wire core.

[0017] The present invention enables the arc-shaped pressure strip to be 5-10 cm behind the position of the cable insulation to be cut, and then controls the arc-shaped pressure strip to continue pressing the cable downward, so that the front end of the cable is more tilted upward with the arc-shaped pressure strip as a reference point, so that water droplets inside the insulation will flow backward in the hollow structure of the insulation, so that when cutting, it can be prevented that the water droplets splash out and adhere to the wire core.

[0018] The two half rings are combined to form a circular ring to wrap the cable, and the insulation on the surface of the cable is pressed inward to form a depression at the half ring, so that the water droplets in the insulation gather at the depression and stay away from the cutting part. The water droplets inside the insulation are then frozen by the low-temperature half ring to make it lose fluidity. In this way, when the cutter cuts the insulation, the water droplets inside the insulation are prevented from flowing outward, splashing out, and sticking to the wire core due to the vibration caused by the cutting.

[0019] During the cutting process, dry air blown out obliquely through the air outlet blows on the wire core entering the box, preventing it from having excessive contact with the humid air in the underground pipeline and forming an oxide layer.

[0020] The present invention blows low-temperature airflow to the buckle behind it through the blowing groove, so that the insulating skin is cooled and brittle; in this way, after the screws on the buckle are removed, when the moving box moves backward, the two half rings can be combined to form a conical ring with a larger front and a smaller rear, so that the upper half and the lower half of the buckle and the insulating skin can be quickly separated, thereby avoiding serious damage when the buckle is separated from the buckle.

DETAILED DESCRIPTION

[0029] The following descriptions are merely preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.

[0030] Example 1

[0031] A device for recycling and reusing defective fireproof insulation cables, such as Figure 1-Figure 7 As shown, it includes a moving box 1 and a cover plate 2; a plurality of rollers are arranged at the bottom of the moving box 1; the moving box 1 is composed of two box bodies distributed up and down; each box body of the moving box 1 is detachably connected with a cover plate 2;

[0032] It also includes a connecting plate 3, a reel 4, a cutter 5, a telescopic supporting block 6, a first electric push rod 7 and an electric screwdriver 8; each cover plate 2 is detachably connected to a connecting plate 3; the middle part of the upper connecting plate 3 is provided with two through holes 3b distributed on the left and right; the lower connecting plate 3 is also provided with a plurality of through holes 3b; the middle part of the connecting plate 3 is set to a deformable material; a reel 4 is provided inside each box body of the mobile box 1; a telescopic electric cutter 5 is provided between the two boxes of the mobile box 1, and the cutter 5 is located above the cable 001; the mobile box 1 is bolted with a telescopic supporting block 6; four first electric push rods 7 distributed in a rectangular shape are provided on the lower surface of the upper box body; an electric screwdriver 8 is provided on the telescopic part of each first electric push rod 7.

[0033] It also includes a multi-section push rod 103 and a disc 104; at least three multi-section push rods 103 are arranged on the left side of the lower box; and a disc 104 is arranged on the telescopic part of each multi-section push rod 103.

[0034] It also includes a pneumatic push rod 101 and a telescopic support plate 102; at least two pneumatic push rods 101 are arranged on the rear side of the lower box; the telescopic parts of all the pneumatic push rods 101 are commonly fixedly connected to a telescopic support plate 102, and the cable 001 to be stripped is straightened by moving the telescopic support plate 102 backward.

[0035] It also includes a guide roller 14; the lower box is equipped with the guide roller 14, and the guide roller 14 is located below the wire core 001a.

[0036] The insulation stripping process of the present invention is as follows:

[0037] The buckle 002 is divided into an upper part and a lower part. The lower part of the buckle 002 is fixed to the wall, and the upper part and the lower part of the buckle 002 are connected by bolts.

[0038] First, the movable box 1 is placed in the underground pipeline, and then the operator pushes the movable box 1 in the underground pipeline to move to the area where the cable 001 is damaged; then, the operator cuts off the front end of the damaged cable 001, places the front end of the cable 001 on the telescopic support block 6, supports the cable 001 by the telescopic support block 6, and then partially peels off the insulation of the front end of the cable 001 to expose the wire core 001a inside it, and then pulls up the two wire cores 001a located at the upper part of the cable 001 and spaced apart, and then inserts the wire core 001a into the through hole 3b on the connecting plate 3, so that the wire core 001a passes through the through hole 3b and is exposed from the rear part of the connecting plate 3, and then the wire core 001a is placed and wound on the reel 4 above, and then the cover plate 2 and the connecting plate 3 are assembled on the movable box 1, as shown in FIG. Figure 2As shown, at this time, the two wire cores 001a pulled upward can be reeled up by the upper reel 4; similarly, the other wire cores 001a are wound on the lower reel 4, and the other wire cores 001a are reeled up by the lower reel 4;

[0039] In this way, the two wire cores 001a with a gap at the top are pulled upward, and the other wire cores 001a are pulled downward, so that the insulation skin on the upper part of the cable 001 is tilted upward, and there is no wire core 001a below the middle part of the upward tilted insulation skin, and it is in a vacant state. At this time, the middle part of the upward tilted insulation skin is cut by the cutter 5, and the insulation skin can be peeled off smoothly, which is not only convenient for cutting, but also can avoid damage to the wire core 001a.

[0040] As the cable 001 cutting operation proceeds, the operator simultaneously pushes the moving box 1 backwards, and the reel 4 also simultaneously reels the wire core 001a. During this process, when the first electric push rod 7 is located above the buckle 002, the telescopic part of the first electric push rod 7 is controlled to drive the electric screwdriver 8 to move downward, so that the electric screwdriver 8 is inserted into the screw on the buckle 002, and then the electric screwdriver 8 is controlled to drive the screw to rotate and remove the screw, and then the operator removes the upper part of the buckle 002, so that the cable 001 can be smoothly detached from the buckle 002;

[0041] Since part of the wire core 001a will be pulled downward and reeled in the reel 4 below during the above-mentioned stripping operation, when the moving box 1 moves backward, the wire core 001a that is pulled downward will be stuck in the lower half of the buckle 002 and cannot continue to move backward. Therefore, it is necessary to make the moving box 1 drive the cable 001 to move to the right, so that the cable 001 to be stripped can first be separated from the lower half of the buckle 002, and at the same time, the wire core 001a that is pulled downward will no longer be stuck by the lower half of the buckle 002. Subsequently, after pushing the moving box 1 backward, move it to the left close to the cable 001, and repeat the above-mentioned stripping operation.

[0042] However, since the cable 001 is located on the telescopic support block 6 and the reel 4 has wound up the wire core 001a, the moving resistance of the mobile box 1 is large. At this time, the telescopic part of the multi-section push rod 103 is controlled to drive the disc 104 to be pushed out to the left, so that the disc 104 contacts the wall. Subsequently, the telescopic part of the multi-section push rod 103 is controlled to continue to be pushed out to the left. In this way, the mobile box 1 connected to the fixed part of the multi-section push rod 103 can be pushed to the right through the reaction force of the wall, thereby reducing the difficulty of the operator in moving the mobile box 1.

[0043] It should be noted that when the moving box 1 drives the front end of the cable 001 to move to the right, the cable 001 will be partially bent, which will increase the difficulty of subsequent cutting of the insulation skin; therefore, before stripping the insulation skin of the cable 001, first control the telescopic part of the telescopic support plate 102 to move upward to support the lower part of the cable 001, and then control the telescopic part of the pneumatic push rod 101 to drive the telescopic support plate 102 to move backward, and the cable 001 to be stripped will be straightened by the telescopic support plate 102 moving backward.

[0044] It should be noted that if Figure 2 As shown, the wire core 001a pulled downward is supported by the guide roller 14 to prevent the insulation skin at the bottom of the cable 001 from being pressed downward when the wire core 001a is pulled downward, resulting in increased resistance to the insulation skin rising upward, thereby affecting the rising of the insulation skin at the top of the cable 001 and affecting the normal stripping work.

[0045] Example 2

[0046] On the basis of Example 1, Figure 1-5 As shown, an anti-adhesion unit is also included, which includes a second electric push rod 10 and an arc-shaped pressure strip 11; the second electric push rod 10 is installed on the upper surface of the lower box; the telescopic part of the second electric push rod 10 is fixedly connected to the arc-shaped pressure strip 11.

[0047] The anti-adhesion unit also includes a third electric push rod 12, a half ring 13, an air injection pipe 15 and a ventilation plate 204; a third electric push rod 12 is respectively arranged on the facing surfaces of the two boxes; a ventilation plate 204 is respectively arranged on the telescopic part of each third electric push rod 12; each ventilation plate 204 is respectively arranged with a half ring 13, and the two half rings 13 are combined together to form a circular ring, and the half ring 13 is arranged as a hollow structure; the ventilation plate 204 is connected with the air injection pipe 15, and the air injection pipe 15 is arranged as a telescopic structure.

[0048] Connect the air injection pipe 15 to the cold air delivery equipment;

[0049] At present, in order to ensure the structural strength of cable 001 and reduce the possibility of cracking of the insulation due to internal stress, some cables 001 will use a double-layer hollow structure insulation, such as Figure 1 As shown; since the insulation skin of cable 001 is a double-layer hollow structure, and there is a large amount of water vapor in the underground pipeline, when the insulation skin is damaged, part of the water vapor will enter the double-layer structure of the insulation skin and form water droplets. When the insulation skin is cut, if the water droplets splash out and adhere to the wire core 001a, the wire core 001a will be oxidized and rusted, thereby affecting the conductivity of the wire core 001a.

[0050] Therefore, before cutting the insulation of the cable 001, the telescopic portion of the second electric push rod 10 is controlled to drive the arc-shaped pressure strip 11 to move downward, so that the arc-shaped pressure strip 11 covers the upper part of the cable 001, as shown in FIG. Figure 1 As shown, the arc-shaped pressure strip 11 is placed 5-10 cm behind the part of the cable 001 insulation to be cut. Then, the arc-shaped pressure strip 11 is controlled to continue pressing the cable 001 downward, so that the front end of the cable 001 is tilted upward more with the arc-shaped pressure strip 11 as the reference point. In this way, the water droplets inside the insulation will flow backward in the hollow structure of the insulation. In this way, when cutting, it can be avoided that the water droplets splash out and adhere to the wire core 001a.

[0051] When the water droplets flow backward in the hollow structure of the insulating skin, the water droplets will gather together. At this time, the telescopic part of the third electric push rod 12 is controlled to drive the two ventilation plates 204 and the semi-ring 13 to move toward each other. The two semi-rings 13 are combined to form a circular ring to wrap the cable 001, and the insulating skin on the surface of the cable 001 is pressed inward to form a depression at the semi-ring 13, so that the water droplets in the insulating skin gather at the depression and stay away from the cutting part. Subsequently, the cold air delivery equipment is controlled to inject cold air into the semi-ring 13 through the air injection pipe 15 and the ventilation plate 204 in turn to reduce the temperature of the semi-ring 13, and the water droplets inside the insulating skin are frozen by the low-temperature semi-ring 13 to make it lose fluidity. In this way, when the cutter 5 cuts the insulating skin, the water droplets inside the insulating skin can be prevented from being affected by the vibration generated by the cutting, and flowing outward, splashing, and adhering to the wire core 001a.

[0052] Because there are only a few water droplets inside the insulating skin, the freezing speed is very fast and the formed ice layer is very thin. When the water droplets are about to be cut, the control half ring 13 continues to press the insulating skin inward to quickly crush the thin ice layer so that it can quickly melt into water droplets and continue to flow backwards to repeat the above operation.

[0053] Example 3

[0054] On the basis of Example 2, Figure 2-7 As shown, it also includes an anti-oxidation unit, which includes a hollow cooling plate 201, an air pump 202 and a ventilation pipe 203; the upper box is equipped with a hollow cooling plate 201, and the hollow cooling plate 201 is connected to the air injection pipe 15; the hollow cooling plate 201 is provided with an air pump 202; the hollow cooling plate 201 is connected to the ventilation pipe 203, and the ventilation pipe 203 is connected to the lower box; the connecting plate 3 is provided with an air outlet 3a, and the air outlet 3a is inclined toward the cable 001.

[0055] The anti-oxidation unit also includes a support plate 205 and a collection box 206; the ventilation plate 204 is connected to two support plates 205 distributed on the left and right; the support plate 205 is set to a hollow structure; the two support plates 205 are commonly connected to the cutter 5; the front of the support plate 205 is provided with an air outlet slot 205a; the two support plates 205 are commonly bolted to a collection box 206, and the collection box 206 is in contact with the cutter 5, and the collection box 206 is connected to the support plate 205.

[0056] Because there is a lot of water vapor in the underground pipeline and the air is humid, when the wire core 001a is stripped from the insulation and comes into contact with the humid air in the underground pipeline, some water vapor will adhere to the wire core 001a, causing oxidation reaction of the wire core 001a;

[0057] Therefore, after the wire core 001a is wound on the reel 4 and the cover plate 2 is connected to the moving box 1, the air pump 202 is controlled to inject air into the hollow cooling plate 201, and the moisture in the air is condensed into water droplets through the hollow cooling plate 201, which are gathered in the hollow cooling plate 201 and discharged from the drainage groove 201a. After the air passes through the hollow cooling plate 201 from left to right and is condensed, it becomes dry air;

[0058] Subsequently, the dry air will flow upward from the air outlet slot 201b into the upper box, and enter the lower box through the ventilation pipe 203. In this way, the air in the box is squeezed out from the air outlet 3a through this part of the dry air. When the air in the box is exhausted, the dry air blown out from the air outlet 3a is the dry air. At this time, cutting and winding work can be carried out. During the cutting process, the dry air blown obliquely through the air outlet 3a blows on the wire core 001a entering the box to prevent it from having too much contact with the moist air in the underground pipeline and forming an oxide layer.

[0059] At the same time, dry air is injected into the support plate 205 through the hollow cooling plate 201, the air injection pipe 15, and the ventilation plate 204 in turn, and then blown forward from the air outlet 205a, guiding the oblique airflows blown out from the upper and lower air outlets 3a to avoid collision between the upper and lower air flows, resulting in air flow turbulence and affecting the normal blowing operation of the core 001a.

[0060] It should be noted that when the cutter 5 cuts the insulation skin, since the insulation skin is made of plastic, it will partially melt when rubbed against the cutter 5, so some insulation skin debris will be attached to the side of the cutter 5, and the collection box 206 is in contact with the cutter 5, and the collection box 206 is connected to the support plate 205. Therefore, the low-temperature air entering the support plate 205 will also enter the collection box 206, so that the collection box 206 remains at a low temperature. In this way, the side of the cutter 5 can be scratched by the low-temperature collection box 206, reducing the residual insulation skin on the side of the cutter 5. At the same time, since the collection box 206 is in a low-temperature state, the adhesion of the insulation skin is reduced, which is convenient for cleaning.

[0061] Example 4

[0062] On the basis of Example 3, Figure 6 As shown, a blowing slot 13a is provided on the rear side of each half ring 13; the cooling airflow blown out by the blowing slot 13a cools the buckle 002 and the cable 001 skin.

[0063] The two half rings 13 are combined to form a conical ring with a larger front and a smaller back. The buckle 002 is pushed open by the conical ring, and the insulating skin remaining on the buckle 002 is scraped off.

[0064] After long-term use, the buckle 002 may be bonded to the insulation, making it difficult to separate the insulation from the buckle 002, and insulation residue may remain on the buckle 002.

[0065] Therefore, a low-temperature airflow can be blown toward the buckle 002 behind it through the blowing groove 13a to cool and embrittle the insulating skin; in this way, after the screws on the buckle 002 are removed, when the moving box 1 moves backward, the two half rings 13 can be combined to form a conical ring that is larger in the front and smaller in the back, so as to quickly separate the upper and lower parts of the buckle 002 and the insulating skin, thereby avoiding serious damage when separating from the buckle 002. In addition, the conical ring can also be used to scratch the inner side of the buckle 002 to scrape off the residual and embrittled insulating skin thereon, thereby ensuring that the insulating skin and the buckle 002 can be quickly separated.

[0066] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
