[0002] The installation of high-voltage cable accessories is one of the common tasks in the power construction process. When installing the cable, a certain length of the cable sheath needs to be cut off. In the prior art, it is generally handled manually. For example, the construction workers hold a blade to cut and cut the cable sheath. However, the cable sheaths of some large hard cables are relatively hard, and the construction workers need to spend more effort to cut and cut the cable sheath. Using more force means that the construction workers' control over the blade is relatively unstable. Under the action of inertia, it is not only easy to cut the longer cable sheaths, but also easy to hurt themselves. In addition, it is easy to have the problem of excessive cutting depth causing damage to the cable core. Based on this, the present invention proposes a cable cutting and stripping device based on automated power engineering, which can realize automatic cutting and stripping of cable sheaths and has controllable cutting length and depth.

[0026] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0027] In the drawings of the present application, a refers to the cable to be cut and stripped. The present application is aimed at the cutting and stripping of large rigid cables, which are not easy to bend.

[0028] Reference Figure 1-Figure 6A cable stripping device for automated power engineering includes a clamping mechanism 100 and a stripping mechanism 200, wherein the clamping mechanism 100 is used to clamp the device on the cable to be stripped, and the stripping mechanism 200 is used to strip the outer sheath of the cable, and the stripping length and depth are controllable.

[0029] 1. Clamping mechanism 100:

[0030] Reference Figure 3 The clamping mechanism 100 includes a mounting bracket 101 , on which a screw rod 103 and a clamping bracket 102 are mounted.

[0031] The screw rod 103 is rotatably connected to the mounting bracket 101 , and a knob 104 is provided at the end of the screw rod 103 . The screw rod 103 can be driven to rotate by turning the knob 104 . Furthermore, the screw rod 103 is divided into two thread segments with opposite thread rotation directions along the axis direction.

[0032] The clamping bracket 102 is slidably connected to the mounting bracket 101, and the sliding direction of the clamping bracket 102 is parallel to the axial direction of the screw 103. Two clamping brackets 102 are arranged along the axial direction of the screw 103. The two clamping brackets 102 are respectively threadedly connected to the two threaded segments of the screw 103. When the screw 103 rotates, the two clamping brackets 102 move toward or away from each other.

[0033] The two clamping brackets 102 are each provided with a clamping plate on one side facing each other. The clamping plate is composed of two side plates and is in a V shape as a whole. When the two clamping brackets 102 move towards each other, the movement direction is named direction one. The two side plates of the clamping plate provided on the clamping bracket 102 increase along direction one. When in use, the device is moved so that the cable is located between the two clamping plates. Then, the two clamping brackets 102 are driven to move towards each other to clamp the cable, that is, the device is fixed on the cable. It should be noted that when the outer sheath of the cable is cut and stripped, the stripping length is generally only tens of millimeters, for example, 150mm. 2 Cable stripping length: 70mm, 400mm 2 The cable stripping length is 90mm. Since the device is for hard cables, after the device is clamped on the cable, the distance between the cable end and the clamping position is shorter. After the device is placed directly on the ground, the part between the cable end and the clamping position is the section to be cut and stripped, and the section to be cut and stripped is straight without bends.

[0034] 2. Cutting and stripping mechanism 200:

[0035] Reference Figure 3The cutting and stripping mechanism 200 includes a connecting bracket 201 and a linear module 202 installed on the mounting bracket 101. The connecting bracket 201 is slidably connected to the mounting bracket 101, and the sliding direction of the connecting bracket 201 is perpendicular to the axial centerline direction of the screw 103. Therefore, when the device is clamped and connected to the cable through the clamping mechanism 100, the sliding direction of the connecting bracket 201 is parallel to the extension direction of the cable section to be cut and stripped. The linear module 202 is used to drive the connecting bracket 201 to move, which can be the existing electric telescopic rod technology, or the existing screw linear motion technology, etc. In this application, the existing linear screw stepper motor technology is selected.

[0036] A mounting sleeve 203 is provided at one end of the connecting bracket 201, and the two clamping brackets 102 are arranged symmetrically about the axis of the mounting sleeve 203. When the device is clamped and connected to the cable by the clamping mechanism 100, the mounting sleeve 203 is located on the side of the connecting bracket 201 facing the cable section to be cut and stripped.

[0037] Reference Figure 4 A rotating sleeve 206 is coaxially installed in the mounting sleeve 203, and the rotating sleeve 206 is rotationally connected to the mounting sleeve 203. A motor 204 arranged on the connecting bracket 201 and the rotating sleeve 206 are power-connected via a power transmission member 205, and the rotating sleeve 206 can be driven to rotate by the motor 204.

[0038] At least two groups of cutting and stripping components are arranged in an array along the circumferential direction on the outer circumferential surface of the rotating sleeve 206 .

[0039] Reference Figure 4-Figure 6 The cutting and stripping assembly includes a support 207 arranged on the outer cylindrical surface of the rotating sleeve 206, a threaded shaft 210 is installed on the support 207 along the radial direction of the rotating sleeve 206, a tool holder 211 is installed at one end of the threaded shaft 210 facing the axis line of the rotating sleeve 206, a cutting and stripping knife 212 is installed on the tool holder 211, and the axis line of the cutting and stripping knife 212 is perpendicular to the axis line of the threaded shaft 210. Preferably, the cutting and stripping knife 212 is rotatably connected to the tool holder 211.

[0040] The two groups of cutting and stripping components are driven by a driving component arranged on the support 207 to cut and strip the cable sheath.

[0041] Reference Figure 5 and Figure 6The driving assembly includes a second motor 208 and a third motor 209 respectively arranged on the supports 207 of the two groups of cutting and stripping assemblies. The second motor 208 and the threaded shafts 210 of the two groups of cutting and stripping assemblies are connected to each other through a first power connecting member, and the third motor 209 and the threaded shafts 210 of the two groups of cutting and stripping assemblies are connected to each other through a second power connecting member. Through the cooperation of the second motor 208 and the third motor 209, the threaded shaft 210 can be driven to perform the following actions: move along the axis centerline direction, which is named feeding action; rotate around the axis centerline direction, which is named switching action.

[0042] Further, see Figure 6 A threaded connection is formed between the driven member of the first power connecting member and the threaded shaft 210, and both ends of the driven member of the first power connecting member are in contact with the support 207, and are restricted to only be able to rotate.

[0043] A sliding connection is formed between the follower of the second power connector and the threaded shaft 210 along the axial direction of the threaded shaft 210. For example, a protrusion is provided on the inner wall of the follower of the second power connector, and a slide groove is provided along the axial direction on the outer cylindrical surface of the threaded shaft 210. The protrusion slides in the slide groove, thereby forming a sliding connection between the follower of the second power connector and the threaded shaft 210. In addition, both ends of the follower of the second power connector are in contact with the support 207 and are restricted to only rotate.

[0044] When motor three 209 is not running and motor two 208 is running, the threaded shaft 210 only moves along the axis direction, that is, a feeding action occurs; when motor three 209 is running, it will rotate with the threaded shaft 210. Since the driven member of the first power connecting member and the threaded shaft 210 form a threaded connection, the threaded shaft 210 rotates while moving along the axis. At the same time, motor two 208 is running, driving the threaded shaft 210 to move in the opposite direction along the axis, which offsets the movement driven by motor three 209, thereby driving the threaded shaft 210 to rotate only around the axis, that is, a switching action occurs.

[0045] Preferably, the motor 208 and the motor 3 209 need to rotate along with the rotating sleeve 206 , and therefore, a through-hole slip ring may be provided outside the rotating sleeve 206 to facilitate the power supply of the motor 208 and the motor 3 209 .

[0046] Working principle of the present invention:

[0047] First, move the device so that the cable is located between the two clamping plates, and then rotate the screw 103 by the knob 104 to move the two clamping brackets 102 closer to each other, thereby clamping the cable and fixing the device on the cable. It should be noted that, initially, Figure 1As shown, the axis of the cutting and stripping knife 212 is parallel to the extension direction of the cable section to be cut and stripped. When the device is fixed on the cable, the position corresponding to the cable and the cutting and stripping knife 212 is the cut-off point of the section to be cut and stripped. Since errors are allowed when stripping the cable, the staff can fix the device at a suitable position of the cable according to their own experience.

[0048] Then, the rotating sleeve 206 is driven to rotate by the motor 1 204, and at the same time, the motor 208 and the motor 3 209 cooperate to drive the threaded shaft 210 to move close to the cable, and the two cooperate with the cutting and stripping knife 212 to cut off the cable sheath;

[0049] Then, the motor 208 and the motor 3 209 cooperate to drive the threaded shaft 210 to move away from the cable, so that the cutting and stripping knife 212 leaves the cable. Figure 2 As shown, the threaded shaft 210 is driven to rotate by the cooperation of the motor 208 and the motor 3 209, so that the axis of the cutting and stripping knife 212 is perpendicular to the extension direction of the cable. After that, the threaded shaft 210 is driven to move close to the cable by the cooperation of the motor 208 and the motor 3 209, and the connecting bracket 201 and the cutting and stripping knife 212 are driven to move along the extension direction of the cable by the linear module 202, so as to realize the cutting and stripping of the cable sheath. It should be noted that, at the beginning, the cutting and stripping knife 212 does not cut the cable sheath, that is, the feeding distance is not enough to completely cut the sheath, therefore, it is necessary to reciprocate several times along the extension direction of the cable to realize the cutting of the cable sheath;

[0050] At this point, the cable sheath is cut off, divided into two, and cut off along the circumferential direction, thereby achieving the cutting and stripping of the cable sheath.

[0051] In summary, the present application can realize the automatic cutting and stripping of the cable sheath, and the cutting length and cutting depth can be controlled by the staff. For example, the cutting length is determined by the staff initially clamping the device and connecting it to the cable. A controller for controlling the operation of the motor is provided on the mounting bracket. The data of the controller can be adjusted in advance to control the distance at which the motor two and the motor three cooperate to drive the threaded shaft to feed. The controller can be realized by existing technology and will not be elaborated on.

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention.
