Description

TECHNICAL FIELD

[0001] The utility model relates to a wire stripping equipment technical field especially, it relates to a kind of high-efficiency electric power cable stripping device. BACKGROUND

[0002] When cable is laid, cable waste will be inevitably generated by cable cutting, and old and damaged cable will be replaced during power equipment maintenance. At present, for this kind of cable, the outer skin needs to be stripped to recover the internal core, and the stripping device is commonly used for stripping the outer skin of the cable. The cable skin can be stripped by the stripping device to improve work efficiency.

[0003] REFERENCE Figure 1 、 Figure 2 A kind of simple and efficient wire stripper is disclosed in Chinese utility model patent with application No.CN202322364724.1, which includes wire stripping frame 100, clamping seat 200 and cutting wheel sheet 302. Cutting sheet 302 is rotatably arranged below feed shaft 400. Feed shaft 400, located inside wire stripping frame 100, has a row of pin holes 401 at both ends, and the two rows of pin holes 401 are symmetrically arranged on both sides with cutting wheel sheet 302 as the center. Two inclined face idlers 402 are symmetrically arranged on feed shaft 400 with cutting wheel sheet 302 as the center. Positioning sleeve 403 is arranged on both inclined face idlers 402 and is sleeved on feed shaft 400. Bolt fixing piece 404, which is matched with pin hole 401, is arranged on positioning sleeve 403. Positioning sleeve and inclined face idler can slide on feed shaft. By positioning positioning sleeve through pin hole 401, the spacing distance of two inclined face idlers can be adjusted to adapt to cables of different sizes.

[0004] However, since positioning sleeve is positioned by pin hole 401, there is a certain spacing distance between adjacent pin holes, which leads to non-linear adjustment of the spacing distance of two inclined face idlers. In some cases, the spacing distance of two inclined face idlers cannot be well adapted to the diameter of cable, which leads to poor contact between the surface of inclined face idler and the outer surface of cable, small contact area and not tight extrusion, small friction between them, and thus slippage between inclined face and cable when rotating two inclined face idlers to drive cable movement. When slipping, cable cannot be effectively driven to move, so that cable cannot be effectively stripped. UTILITY MODEL CONTENT

[0036] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0037] For details, please refer to Figure 1 , Figure 2 It should be noted that the high-efficiency power cable stripping device provided in this application also includes structures such as a stripping frame 100, a clamping base 200, and a cutting wheel 302. The difference between this application and the prior art is that, please refer to... Figures 3-7 The technical solution of this utility model is: a high-efficiency power cable stripping device, including a feed shaft 400, an inclined support roller 402, and a positioning sleeve 403, and further including:

[0038] Rack 4001 is mounted on feed shaft 400 along the axial direction of feed shaft;

[0039] The positioning shaft 6 is axially inserted into the positioning sleeve 403 and its axis is perpendicular to the axis of the feed shaft;

[0040] Gear 7 meshes with rack 4001 and is slidably sleeved on positioning shaft 6;

[0041] The positioning shaft 6 is provided with a connector 61. One of the positioning sleeve 403 and the gear 7 is non-rotatably engaged with the positioning shaft 6, and the other is provided with a connector 62 that is engaged with the connector.

[0042] Specifically, the feed shaft 400 is rotatably engaged with the wire stripping frame 100, and the inclined support roller 402 can slide along the axial direction of the feed shaft 400. (Refer to...) Figures 3-5 A rack 4001 is provided on one side of the feed shaft, for reference. Figure 6 The positioning sleeve 403 is provided with a positioning shaft 6, which can slide relative to the positioning sleeve along the axial direction. As a specific implementation method, see reference. Figure 9 The gear 7 is equipped with a key 71, and the outer circumferential surface of the positioning shaft 6 is equipped with a keyway 64. The key can slide within the keyway. The connector 61 is located at one end of the positioning shaft 6. In actual use, it can push the positioning shaft 6 to move axially. When the connector 61 and the connector 62 are engaged, the connector can circumferentially limit the connector 61, restricting its rotation around the axis, thereby restricting the positioning shaft 6 from rotating around the axis. At this time, the gear cannot rotate freely, and the positioning sleeve 40 can be positioned by the engagement of the gear and rack 4001. 3. Axial limiting is performed to restrict the sliding of the positioning sleeve and the inclined support roller. When the position of the inclined support roller needs to be adjusted, the positioning shaft 6 is pushed to move axially, so that the plug-in part 61 is separated from the plug-in part 62. At this time, the positioning shaft 6 and the positioning sleeve 403 can rotate freely. At this time, the gear 7 can also rotate relative to the positioning sleeve 403. At this time, pushing the mounting sleeve can slide the mounting sleeve on the feed shaft 400 for position adjustment. In this way, the adjustment linearity of the mounting sleeve can be improved, and it can be better adapted to cables of different sizes, thus improving adaptability.

[0043] Specifically, in some embodiments, the feed shaft is also provided with scale lines, so that the position of the mounting sleeve can be adjusted according to the scale lines, thereby improving the convenience of adjustment.

[0044] Furthermore, the positioning shaft 6 is keyed to the gear 7, the plug-in 61 is a cylinder coaxially disposed at the end of the positioning shaft, the outer circumferential surface of the cylinder is provided with positioning tooth groove 610, the plug-in part 62 is a blind hole disposed on the side wall of the positioning sleeve 403, one of the inner side wall of the blind hole and the outer circumferential surface of the cylinder is provided with positioning tooth groove 610, and the other is provided with positioning protrusion 611.

[0045] Specifically, as one specific implementation method, refer to Figures 8-10The connector 61 is a cylinder with evenly spaced external teeth on its outer circumference. The tooth groove 610 is the tooth groove of the external teeth. A through hole 4032 is provided on the side of the positioning sleeve. The positioning shaft 6 rotates with the through hole 4032. The connector 62 is a blind hole coaxial with the through hole. Internal teeth that engage with the external teeth are provided on the side wall of the blind hole. The positioning protrusion is the tooth of the internal teeth. Through the engagement of the internal and external teeth, the positioning shaft 6 can engage with the external teeth when rotating by one tooth angle, further improving the adjustment linearity of the positioning sleeve. Furthermore, through the engagement of the internal and external teeth, they contact each other. When stripping the cable, the inclined roller... The cable provides support and exerts a counterforce on the inclined roller, which tends to push the inclined roller to the sides. At this time, the internal and external teeth mesh together to prevent the gear 7 from rotating. The gear and rack cooperate to prevent the inclined roller from moving. At this time, the tooth surfaces between the internal and external teeth press against each other and have friction. Under the action of this friction, a certain axial resistance can be provided to the connector, which can reduce the probability of the connector separating from the connector. When the cable is not cut, the inclined roller is not subjected to axial force, so there is no mutual pressing force between the internal and external teeth. At this time, the positioning shaft can be pushed to move axially, thereby driving the connector 61 to move and causing the connector to separate from the connector.

[0046] Furthermore, as a specific implementation, the positioning sleeve 403 has an installation channel 4031 on its side wall, and two mounting plates 4030 are arranged parallel to each other on both sides of the installation channel 4031. The mounting plates 4030 are provided with through holes 4032 that are rotatably engaged with the positioning shaft 6.

[0047] Specifically, by setting up an installation channel and a mounting plate 4030, with through holes 4032 set on the mounting plate, this method facilitates the installation of gear 7 and positioning shaft 6, and the structure is reasonable.

[0048] Furthermore, a limiting member 63 is also provided at the end of the positioning shaft 6 away from the insertion member 61. As a specific embodiment, refer to... Figure 9 , Figure 10 One end of the positioning shaft is connected to the connector 61, and the other end passes through two mounting plates 4030 and gear 7 in sequence. A limiting member 63 is provided at the other end. By setting the limiting member, the positioning shaft 6 can be limited, and the positioning shaft is prevented from disengaging from the positioning sleeve 403 when the positioning shaft 6 is pushed to move axially.

[0049] Furthermore, one of the limiting member 63 and the plug-in member 61 is detachably connected to the positioning shaft 6. Specifically, refer to... Figure 9 , Figure 10In one implementation, the positioning shaft 6 and the plug-in 61 are integrally formed and threadedly connected to the limiting member 63, wherein the limiting member is a circular plate-shaped structure.

[0050] Furthermore, the cross-section of the feed shaft 400 is a regular polygon, and a groove 4002 is provided on one side of the feed shaft 400 along the axial direction. At least one end of the groove 4002 penetrates the end face of the feed shaft, and the rack 4001 is provided at the bottom of the groove 4002.

[0051] Specifically, in a particular implementation, the feed shaft has a regular hexagonal cross-section, and the internal channels of the positioning sleeve and the inclined support roller 402 are also regular hexagonal channels, as shown in the reference. Figure 4 , Figure 9 By setting a groove 4002 on the surface of the feed shaft and setting the rack 4001 at the bottom of the groove, the gear 7 can be axially limited by the side of the groove, so that the gear will not move excessively in the axial direction when the positioning shaft 6 moves axially, thus ensuring that the gear can effectively mesh with the rack.

[0052] Furthermore, both ends of the feed shaft 400 are coaxially provided with connecting shafts 4003, and each connecting shaft 4003 is plugged into and connected with a connecting sleeve 8. The connecting sleeve 8 is in a non-rotational engagement with the connecting shaft 4003. Specifically, as one embodiment, both ends of the feed shaft 400 are provided with connecting shafts 4003 with a regular hexagonal cross-section, and plugged sleeves 8 are plugged into the connecting shafts. (Refer to...) Figure 11 , Figure 12 The plug-in sleeve includes a plug-in hole 81 that mates with the connecting shaft. The other end of one plug-in sleeve is provided with a fixing screw hole 82. During the specific assembly process, the two plug-in sleeves 8 are connected to facilitate rotational engagement with the wire stripping frame 100. Both ends of the feed shaft 400 are inserted into the plug-in sleeve. After assembly, the other end of the plug-in sleeve 8 can extend out of the wire stripping frame 100. At this time, the handwheel 405 can be connected through the fixing screw hole 82, and the feed shaft can be driven to rotate through the handwheel 405.

[0053] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
