Description

Technical Field

[0001] The utility model relates to the technical field of cable installation, in particular to an auxiliary device for installing a power cable. Background Art

[0002] Power cables are cables used to transmit and distribute electrical energy. Power cables are commonly used in urban underground power grids, power station lead-out lines, internal power supply for industrial and mining enterprises, and underwater transmission lines across rivers and seas. The basic structure of power cables consists of four parts: core (conductor), insulation layer, shielding layer and protective layer.

[0003] When installing the cable, it is necessary to cut the cable to a suitable length to provide the currently required cable length. After cutting the cable, the outer skin (insulation layer) of one end of the cable needs to be stripped off for a certain length for cable connection. However, most of the existing cables use a stripping device to strip the outer skin of the cable after cutting the cable. Generally, the stripping and cutting of the cable cannot be completed at the same time, which makes the installation of the cable more complicated and the cable installation efficiency is low.

[0086] Wherein, the two extrusion blocks 23 are fixedly connected to the lower surfaces of the two support plates 22;

[0087] The two extrusion blocks 23 are slidably connected to the two fixing grooves 4 .

[0088] Furthermore, four support blocks 14 are fixedly connected to the front and rear outer surfaces of the first fixing block 2 and the second fixing block 3;

[0089] Among them, four adjusting bolts 15 are slidably sleeved on four supporting blocks 14;

[0090] Among them, a plurality of adjusting thread grooves 24 are provided on the upper surface of the base 1;

[0091] The lower end of the adjusting bolt 15 extends into the adjusting thread groove 24 , and the adjusting bolt 15 is threadably connected to the adjusting thread groove 24 .

[0092] Furthermore, a controller is provided on the base 1, and the controller is electrically connected to the motor 17;

[0093] Furthermore, in this solution, the first fixing block 2 and the second fixing block 3 are both placed on the upper surface of the base 1 and are limited by the corresponding adjusting bolts 15, the supporting blocks 14 and the adjusting threaded grooves 24;

[0094] Furthermore, the cable is placed in the two fixed grooves 4 and made to be in a straight line. At this time, the electric push rod 21 is started, and the electric push rod 21 starts to drive the support plate 22 and the extrusion block 23 to move up and down. When the extrusion block 23 moves downward, the power cable is squeezed and fixed between the bottom wall of the fixed groove 4 and its lower surface, thereby achieving the fixation of the cable, thereby avoiding the movement of the cable during the stripping and cutting process of the cable, thereby ensuring the stability of the cutting and stripping, thereby ensuring the quality of the cable cutting and stripping, and also ensuring the quality of the subsequent installation of the cable, thereby increasing the practicality and stability of the auxiliary device.

[0095] Furthermore, by moving the first fixed block 2 or the second fixed block 3 left and right, the adjusting bolt 15 thereon is threadedly connected with different adjusting thread grooves 24 and tightened, so as to achieve the purpose of fixing the first fixed block 2 and the second fixed block 3, and then the distance between the first fixed block 2 and the second fixed block 3 can be adjusted, and then the distance between the cutting knife 6 and the stripping knife 10 can be adjusted synchronously, and then the stripping length of the cable can be adjusted, so that the auxiliary device can be suitable for different stripping length requirements of the cable, thereby increasing the practicality and flexibility of the auxiliary device.

[0096] Furthermore, the cable is placed in the two fixing grooves 4, and the cable is in a straight state, so that the tip of the stripping knife 10 is inserted into the outer sheath of the cable, and then the electric push rod 21 is started to fix the cable, and the controller controls the starting motor 17. The motor 17 starts to drive the worm 18 to rotate, and then synchronously drives the worm wheel 20, the fixing tube 5, the positioning block 13, the fixing rod 12 and the second gear 16 to rotate synchronously. The rotation of the fixing tube 5 drives the cutting knife 6 to cut the cable, and the rotation of the second gear 16 synchronously drives the positioning ring block 9 to rotate. The rotation of the positioning ring block 9 synchronously drives the first gear ring 11 and the two stripping knives 10 to rotate, and the two stripping knives 10 rotate to cut the cable. The outer sheath is cut in a circle. When the motor 17 drives the cutting knife 6 to rotate to an angle that has reached the point where the cable is cut off (at this time, the two stripping knives 10 also synchronously cut the outer sheath of the cable at a certain angle), the controller controls the start motor 17 to rotate in the opposite direction. When the motor 17 rotates in the opposite direction to the point where the rotation angle of the stripping knife 10 can cut the outer sheath of the current cable for one circle (three hundred and sixty degrees), the controller controls the motor 17 to reverse again so that the stripping knife 10 and the cutting knife 6 are reset to the initial state. At this time, the stripping and cutting work of the cable is completed synchronously, making the cable installation more efficient, more labor-saving, and improving the practicality and work efficiency of the auxiliary device.

[0097] Further, it should be noted that the angle between the two peeling knives 10 is greater than the angle of the notch of the positioning ring block 9 .

[0098] Furthermore, the positioning block 13 is slidably connected with the limit groove 19 to restrict the fixing rod 12 and the fixing tube 5, so that the fixing rod 12 and the fixing tube 5 can only move relative to each other but cannot rotate relative to each other, thereby enabling the fixing rod 12 and the fixing tube 5 to rotate at the same time while adjusting the distance between the first fixing block 2 and the second fixing block 3.

[0099] Working principle: When the device is used, the cables are placed in the two fixed grooves 4 and the cables are in a straight state. At this time, the electric push rod 21 is started, and the electric push rod 21 starts to drive the support plate 22 and the extrusion block 23 to move up and down. When the extrusion block 23 moves downward, the power cable is squeezed and fixed between the bottom wall of the fixed groove 4 and its lower surface, thereby fixing the cable, thereby avoiding the movement of the cable during the stripping and cutting process, thereby ensuring the stability of cutting and stripping, and then ensuring the quality of cable cutting and stripping, and also ensuring the quality of subsequent cable installation, thereby increasing the practicality and stability of the auxiliary device.

[0100] Furthermore, the cable is placed in the two fixing grooves 4, and the cable is in a straight state, so that the tip of the stripping knife 10 is inserted into the outer sheath of the cable, and then the electric push rod 21 is started to fix the cable, and the controller controls the starting motor 17. The motor 17 starts to drive the worm 18 to rotate, and then synchronously drives the worm wheel 20, the fixing tube 5, the positioning block 13, the fixing rod 12 and the second gear 16 to rotate synchronously. The rotation of the fixing tube 5 drives the cutting knife 6 to cut the cable, and the rotation of the second gear 16 synchronously drives the positioning ring block 9 to rotate. The rotation of the positioning ring block 9 synchronously drives the first gear ring 11 and the two stripping knives 10 to rotate, and the two stripping knives 10 rotate to cut the cable. The outer sheath is cut in a circle. When the motor 17 drives the cutting knife 6 to rotate to an angle that has reached the point where the cable is cut off (at this time, the two stripping knives 10 also synchronously cut the outer sheath of the cable at a certain angle), the controller controls the start motor 17 to rotate in the opposite direction. When the motor 17 rotates in the opposite direction to the point where the rotation angle of the stripping knife 10 can cut the outer sheath of the current cable for one circle (three hundred and sixty degrees), the controller controls the motor 17 to reverse again so that the stripping knife 10 and the cutting knife 6 are reset to the initial state. At this time, the stripping and cutting work of the cable is completed synchronously, making the cable installation more efficient, more labor-saving, and improving the practicality and work efficiency of the auxiliary device.
