Description

Technical Field

[0001] The invention relates to the technical field of cable lead sheath stripping, in particular to a tool for non-destructive stripping of cable lead sheaths. Background Art

[0002] With the development of offshore wind power high-voltage transmission technology, the application scale of high-voltage submarine cable docking technology is increasing, and its importance is becoming increasingly prominent. In the process of high-voltage transmission, the submarine cable is generally a continuous line that needs to connect various parts as a whole. Generally, the flexible joints are used to connect the parts after the production of each part is completed in the factory. As the most critical link in the entire submarine cable production, the flexible joint has a structural size very close to the submarine cable body, and has the same electrical properties, mechanical properties, bending properties and service life as the submarine cable. As a key link in cable production, its production cycle and qualified rate directly affect the production progress and order delivery time, and also have a great impact on the safety of the cable line.

[0003] Lead sheath has good corrosion resistance, softness and stable extrusion processing performance, and has long been used as a metal sheath for communication cables and paper insulated cables. Since the lead sheath is very soft, it is generally tightly attached to the surface of the cable core during production and extrusion. Therefore, it is easy to scratch the cable core or cause side extrusion of the cable core when stripping the lead sheath. Therefore, it is necessary to develop a tool that can strip the lead sheath more efficiently and without damage. The traditional method of stripping the lead sheath is to first use a utility knife to gently cut a slit in the middle of the upper part of the lead sheath. This slit is about half the thickness of the lead sheath, and then pry it open with a screwdriver. This method is easy to damage the cable body and has high requirements for operation. Summary of the invention

[0004] The technical problem to be solved by the present invention is that the traditional lead sheath stripping process easily damages the cable body and has high requirements on the operation.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a cable lead sheath non-destructive stripping tool, including a main assembly frame, split lateral internal support frames are fixedly installed on both sides of the main assembly frame by bolts, a front cutting head for cutting the cable lead sheath is fixedly installed at the outer end of the main assembly frame, a movable cutting head is movably installed on the outer side of the front cutting head through a connecting shaft, the control end of the movable cutting head has an inclined control handle of an integrated structure, the upper end shaft of the outer side of the main assembly frame is movably connected with a side-mounted control strut for auxiliary control of the inclined control handle, and side flanging covers for facilitating flanging of the cable lead sheath cutting port are fixedly installed on both sides of the inclined control handle.

[0006] The main assembly frame is provided with assembly through holes at the bottom transverse section, the lateral oblique section and the lateral longitudinal section.

[0007] A return spring is movably mounted between the main assembly frame and the inclined control handle.

[0008] An external flip ring is movably inserted into the interior of the oblique control handle, and a top hook matched with the external flip ring is movably mounted on the extended end of the side-mounted control support rod.

[0009] An outer control handle is fixed to the outer longitudinal section of the main assembly frame by bolts.

[0010] A control button for controlling the telescopic adjustment of the side-mounted control strut is installed on the upper end of the side wall of the outer control handle.

[0011] An external lithium battery for the side-mounted control strut is fixedly mounted on the side wall of the main assembly frame.

[0012] The two sides of the lateral inclined section of the main assembly frame are fixedly mounted with inclined adjustment guide rails by means of assembly bolts.

[0013] An external limiting frame for lateral limiting of the side-mounted control support rod is fixedly mounted on the side wall of the main assembly frame.

[0014] A position-adjustable guide wheel set is movably mounted on the outer side of the oblique adjustment guide rail.

[0015] The beneficial effects of the present invention are: (1) The cable lead sheath non-destructive stripping tool of the present invention can greatly reduce the lead sheath stripping efficiency by cutting at the front end and flanging at both sides; (2) Compared with the traditional stripping method, the damage to the cable core caused by this device is greatly reduced; (3) It can be operated manually or electronically, with more diverse operating methods; (4) By adopting the plug-in installation method, it is convenient for later maintenance and reduces the cost of use; (5) The cable sheath can be disassembled and replaced according to the specifications, greatly improving the adaptation effect; (6) The entire stripping mechanism is small in size, easy to operate and carry.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] Figure 1 , Figure 2 and Figure 3 The tool shown is a non-destructive stripping tool for cable sheathing, comprising a main assembly frame 1, with split lateral internal support frames 2 fixedly installed on both sides of the main assembly frame 1 by bolts, a front cutting head 3 for cutting the cable sheathing fixedly installed at the outer end of the main assembly frame 1, a movable cutting head 31 is movably installed on the outer side of the front cutting head 3 through a connecting shaft, the control end of the movable cutting head 31 has an inclined control handle 4 of an integrated structure, a side-mounted control strut 5 for assisting in controlling the inclined control handle 4 is movably connected to the outer upper end shaft of the main assembly frame 1, and side flanging covers 6 for facilitating the flanging of the cable sheath cutting opening are fixedly installed on both sides of the inclined control handle 4.

[0023] Operation principle: first use a circular cutting knife to cut out a circular opening; then use the front cutting head 3 and the movable cutting head 31 to cut a hole of appropriate depth in the center position above the lead sleeve; then insert the split lateral internal support frame 2 into the opening, and then set the incision between the front cutting head 3 and the movable cutting head 31, and then push forward along the incision manually or electrically, and while pushing, press the inclined control handle 4 upward to perform scissor-like cutting, thereby gradually expanding the length of the incision, and at the same time, when the inclined control handle 4 is flipped upward, it drives the side flange 6 to flange the two sides of the opening, thereby expanding the incision.

[0024] In order to facilitate external fixing and assembly, assembly through holes 7 are provided on the bottom transverse section, the lateral oblique section and the lateral longitudinal section of the main assembly frame 1 .

[0025] In order to cooperate with elastic reset, a reset spring 8 is movably installed between the main assembly frame 1 and the inclined control handle 4.

[0026] The two ends of the reset spring 8 are respectively mounted on the main assembly frame 1 and the inclined control handle 4, and are reset by elastic pulling.

[0027] In order to cooperate with the end assembly and separation, an external flip ring 9 is movably penetrated inside the inclined control handle 4, and the extended end of the side-mounted control support rod 5 is movably equipped with a top hook 10 that matches the external flip ring 9.

[0028] The side-mounted control strut 5 is flipped downward, and then the top hook 10 is put on the external flip ring 9. In this way, the side-mounted control strut 5 contracts, thereby controlling the inclined control handle 4 to flip upward, thereby controlling the movable cutting head 31 to flip downward, and then cooperate with the front cutting head 3 to perform shearing.

[0029] In order to cooperate with the lateral assembly control, an outer control handle 11 is fixed to the outer longitudinal section of the main assembly frame 1 by bolts.

[0030] In order to facilitate control and adjustment, a control button 12 for controlling the telescopic adjustment of the side-mounted control support rod 5 is installed on the upper end of the side wall of the outer control handle 11.

[0031] People control the main assembly frame 1 by holding the outer control handle 11. When electric control operation is required, they only need to press the control button 12, and then control the side-mounted control strut 5 to reciprocate and extend. Then the side-mounted control strut 5 controls the tilted control handle 4 to flip and adjust through reciprocating extension and retraction, thereby controlling the movable cutting head 31 to cooperate with the front cutting head 3 to cut the lead sleeve. At the same time, the tilted control handle 4 is reversed upward, and the side flange cover 6 is squeezed and flipped outward, so that the lead sleeve walls on both sides of the incision are flipped outward, thereby expanding the incision size.

[0032] In order to cooperate with autonomous power supply, an external lithium battery 13 for powering the side-mounted control strut 5 is fixedly mounted on the side wall of the main assembly frame 1 .

[0033] The external lithium battery 13 is connected in series with the control button 12 and the side-mounted control strut 5 , and the side-mounted control strut 5 is adjusted and retracted by the control button 12 .

[0034] In order to cooperate with the oblique guidance, oblique adjustment guide rails 14 are fixedly installed on both sides of the lateral oblique section of the main assembly frame 1 by assembly bolts.

[0035] The oblique adjustment guide rail 14 is fixedly assembled with the lateral oblique section of the main assembly frame 1 by means of fixing bolts penetrating the assembly through holes 7 , and an electric control lead screw is movably assembled inside the oblique adjustment guide rail 14 .

[0036] The control button 12 can also independently control the rotation of the electric control screw rod.

[0037] In order to accommodate and limit the side-mounted control stay 5 , an external limit frame 15 for lateral limit of the side-mounted control stay 5 is fixedly mounted on the side wall of the main assembly frame 1 .

[0038] When the side-mounted control strut 5 needs to be stored, the side-mounted control strut 5 is first controlled to retract the extended end, and then the extended end of the side-mounted control strut 5 is aligned with the external limit frame 15, and then the side-mounted control strut 5 is controlled to extend and inserted into the external limit frame 15, thereby limiting the position of the side-mounted control strut 5.

[0039] In order to cooperate with the guide drive adjustment, a position-adjustable guide wheel set 16 is movably mounted on the outer side of the inclined adjustment guide rail 14 .

[0040] The position-adjustable guide wheel group 16 includes an internal thread adjustment block slidably assembled inside the inclined adjustment guide rail 14, an external bracket fixed on the outside of the internal thread adjustment block, and an electric drive wheel installed at the end of the external bracket. The internal thread adjustment block is assembled and adjusted by threading inside the electric control screw inside the inclined adjustment guide rail 14. The position-adjustable guide wheel group 16 is controlled downward to make the position-adjustable guide wheel group 16 contact with the outer surface of the lead sleeve. This not only avoids cutting transition by extrusion limiting, but also facilitates forward or backward movement after cutting, which is convenient for subsequent cutting and separation.

[0041] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
