Description

Technical Field

[0001] The invention relates to the technical field of cable splicing equipment, and in particular to a cable splicing clamp for dam monitoring and a cable splicing method thereof. Background Art

[0002] The regulating reservoir project mainly consists of reservoir dam project, water intake project, water transmission and discharge project, monitoring project and other parts. In the dam monitoring project, it is necessary to jointly protect the safety of cable routing. If abnormal cable damage occurs, it should be repaired and reconnected in time and marked well.

[0003] The cable splicing work is very complicated, especially for the splicing of some multi-core cables. Before wiring, the cable needs to be stripped and the ends of the single core need to be stripped, and then each core needs to be paired. The whole operation process is complicated and cumbersome. In actual use, the common splicing auxiliary clamps on the market are mostly used for auxiliary fixation and stripping, which cannot effectively help the splicing operation, and the auxiliary effect needs to be improved. Summary of the invention

[0004] The invention discloses a cable splicing clamp for dam monitoring and a cable splicing method thereof, aiming to solve the technical problem that most of the common cable splicing auxiliary clamps on the market are mainly used for auxiliary fixing and stripping during actual use, the whole operation process is complicated and cumbersome, and the splicing operation cannot be effectively helped, and the auxiliary effect needs to be improved.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A cable splicing fixture for dam monitoring, comprising a fixture, wherein a stripping mechanism for stripping a cable core is arranged inside the fixture, wherein the stripping mechanism comprises two sets of threading plates and extrusion plates symmetrically installed at two ends of the fixture, wherein the ends of the threading plates penetrate through the fixture and are sleeved with a type of rotating shaft, wherein first thread grooves are provided on the outer sides of both ends of the type of rotating shaft, and the first thread grooves are threadedly connected to the threading plates;

[0007] The fixture is also provided with a connecting mechanism for connecting the cable core, the connecting mechanism comprising a second type of rotating shaft horizontally penetrating the ends of the two extrusion plates, the outer side of the second type of rotating shaft is symmetrically provided with two second thread grooves, and the second thread grooves are threadedly connected to the extrusion plate;

[0008] Both ends of the clamp are provided with fixing mechanisms for clamping the cable;

[0009] The fixing mechanism is used to initially fix and pull the cable, and the stripping mechanism is used to strip the cable core, so that the splicing mechanism completes the splicing work on the stripped cable core.

[0010] By providing a fixing mechanism, the cable inserted into the clamp is fixed to maintain the stability of the cable, and the stripping mechanism for stripping the cable core is cooperated to strip the ends of the cable cores inserted into the clamp. After the stripping of the ends of the cores is completed, the connecting mechanism drives the fixing mechanism to operate, and by controlling the moving speeds of the fixing mechanism and the connecting mechanism, the two groups of cores with the ends stripped are butted and squeezed by the connecting mechanism to complete the connecting work. Different from the traditional cable connection, which requires workers to manually strip and connect the cores one by one, the present clamp can strip and connect all the cores at the same time, thereby greatly improving the efficiency and convenience of traditional cable connection.

[0011] In a preferred embodiment, the wire stripping mechanism also includes a plurality of circular cutting knives fixed on the close surfaces of the two threading plates, and a plurality of first-class extrusion holes are penetrated through the interiors of the two extrusion plates. The circular cutting knives are slidably inserted into the interiors of the first-class extrusion holes and are in extrusion contact with the inner walls of the first-class extrusion holes.

[0012] The extrusion is formed by the threading plate and the extrusion plate driven by a type of rotating shaft. The user passes the cable core between the threading plate and the extrusion plate in advance, and the circular cutting knife arranged on the side of the threading plate cooperates with the extrusion holes arranged inside the extrusion plate to simultaneously strip the ends of the core inside the extrusion plate, thereby completing the stripping of all the cores that need to be connected in the cable at one time, greatly improving the convenience of traditional cable connection.

[0013] In a preferred embodiment, the connecting mechanism further comprises a back plate fixedly connected to the side of each extrusion plate, a plurality of evenly distributed second-type extrusion holes are penetrated through the interior of the back plate, the inner diameters of the two ends of the second-type extrusion holes are different, forming a trumpet-shaped structure, a center plate is fixedly installed inside the clamp, a plurality of wire pressing rings are penetrated through the interior of the center plate, the second-type extrusion holes are extruded and contacted with the ends of the wire pressing rings, and the number of the first-type extrusion holes, the second-type extrusion holes and the wire pressing rings is the same and distributed correspondingly in the horizontal direction.

[0014] By arranging a back plate structure with two types of extrusion holes on the side of the extrusion plate, after completing the stripping process on the ends of the wire cores, as the wire cores are inserted into the inside of the wire pressing ring, the two types of extrusion holes inside the back plate and the wire pressing ring inside the middle plate are squeezed against each other, causing the two ends of the wire pressing ring to deform and clamp and fix the wire cores, completing the cable connection work, thereby completing the connection of all the wire cores of the cable at one time, and further improving the convenience of traditional cable connection.

[0015] In a preferred embodiment, the fixing mechanism includes third thread grooves symmetrically opened at both ends of the second type rotating shafts, and the outer side of each third thread groove is threadedly connected to a clamp for fixing the cable, and the clamps are horizontally distributed at both ends of the clamp.

[0016] The cable is initially fixed by providing a clamp to ensure the stability of the cable during connection. At the same time, the clamp is driven by the second-class rotating shaft with a third thread groove. After the cable core is stripped, the clamp is used to drive the core to be inserted into the wire pressing ring, thereby completing the autonomous connection of the core, facilitating the operation of the subsequent connection mechanism, and ensuring the stability and integrity of the equipment during operation.

[0017] In a preferred embodiment, a positioning film is adhered to the side of the extrusion plate away from the threading plate, an inner recess is provided at the end of each of the circular cutting knives, an outer protrusion is provided inside each of the extrusion holes of the type, and the inner recess and the outer protrusion are snap-fitted and connected.

[0018] A positioning film is provided to shield and position the wire core inserted into the extrusion plate, thereby assisting the operator in completing the initial placement of the cable. At the same time, the inner concave part of the end of the circular cutter is engaged with the outer protrusion inside a type of extrusion hole, so that the circular cutter after stripping the wire core end can squeeze the positioning film in a reset and elastic manner, causing the positioning film to rupture and push out the peeled outer skin, thereby ensuring the integrity of the operation of the equipment.

[0019] As can be seen from the above, the cable splicing fixture for dam monitoring and the cable splicing method provided by the present invention have the following improvements and advantages compared with the prior art:

[0020] After the user passes the cable core between the threading plate and the extrusion plate in advance, the threading plate and the extrusion plate driven by a first-class rotating shaft form an extrusion, and the ring cutting knife arranged on the side of the threading plate cooperates with a first-class extrusion hole arranged inside the extrusion plate to simultaneously strip the ends of all the cores located inside the extrusion plate, so that all the cores that need to be connected in the cable are stripped at one time, and a back plate structure with a second-class extrusion hole is additionally arranged on the side of the extrusion plate. After the stripping of the core ends is completed, the clamp is driven by the second-class rotating shaft to drive the core to move in the center. And insert it into the inside of the crimping ring, so as to complete the autonomous docking of the wire core. As the wire core is inserted into the inside of the crimping ring, the two ends of the crimping ring are squeezed together by the second type of extrusion hole inside the back plate and the crimping ring inside the middle plate, so that the cable connection work is completed, thereby completing the connection of all the wire cores of the cable at one time. Different from the traditional cable connection, which requires workers to manually peel and connect the wire cores one by one, this clamp can strip and connect all the wire cores at the same time, and greatly improve the efficiency and convenience of traditional cable connection.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] A cable splicing clamp for dam monitoring and a cable splicing method thereof disclosed in the present invention are mainly used in the scenario of splicing cable cores.

[0035] Reference Figures 1 to 11 A cable splicing fixture for dam monitoring includes a fixture 1, a stripping mechanism 2 for stripping the cable core is arranged inside the fixture 1, the stripping mechanism 2 includes two sets of threading plates 201 and extrusion plates 205 symmetrically installed at two ends inside the fixture 1, the ends of the threading plates 201 penetrate through the inside of the fixture 1 and are sleeved with a type of rotating shaft 202, the outer sides of the two ends of the type of rotating shaft 202 are provided with first thread grooves 203, and are threadedly connected to the threading plates 201 through the first thread grooves 203;

[0036] The fixture 1 is also provided with a connecting mechanism 3 for connecting the cable cores. The connecting mechanism 3 includes a second type of rotating shaft 301 horizontally penetrating the ends of the two extrusion plates 205. The outer side of the second type of rotating shaft 301 is symmetrically provided with two second thread grooves 302, and is threadedly connected to the extrusion plates 205 through the second thread grooves 302.

[0037] Both ends of the clamp 1 are provided with fixing mechanisms 4 for clamping the cable;

[0038] The fixing mechanism 4 forms a preliminary fixation and pulling of the cable, cooperates with the stripping mechanism 2 to strip the cable core, so that the connecting mechanism 3 completes the connecting work of the stripped cable core.

[0039] In this embodiment: when in use, the operator places the clamp 1 flat on the ground, and holds two cables that need to be connected and places them on both sides of the clamp 1, and at the same time peels off the cable sheaths, arranges the wire cores inside the cable in order, and inserts the wire cores of the same wire sequence from the two ends of the clamp 1 into the wire stripping mechanism 2 inside the clamp 1, and fixes the cable body by the fixing mechanism 4. At this time, the operator manually operates the wire stripping mechanism 2, and the wire stripping mechanism 2 will synchronously strip the sheaths of all the inserted wire core ends. After completing the stripping of the wire core sheaths, the operator manually operates the connecting mechanism 3. While the connecting mechanism 3 is running, it will synchronously drive the fixing mechanism 4, and the fixing mechanism 4 will drive the two cables to center, causing the wire cores to move to the inside of the connecting mechanism 3, and be clamped and fixed by the connecting mechanism 3, completing the cable connection work.

[0040] The outer surface of the clamp 1 is provided with a glass window 5 to facilitate the operator to observe the operating status inside the clamp 1 .

[0041] In the above scheme, considering that in the existing cable connection process, due to the large number of cable cores, the operator needs to complete the stripping process of the single cores one by one, and the efficiency needs to be improved. The specific operations are as follows.

[0042] Reference Figures 3 to 7 In a preferred embodiment, the wire stripping mechanism 2 also includes two wire threading plates 201, both of which are fixed with a plurality of circular cutting knives 204 on their proximal surfaces, and two extrusion plates 205 are each provided with a plurality of first-class extrusion holes 206 running through their interiors, and the circular cutting knives 204 are slidably inserted into the first-class extrusion holes 206 and are in extrusion contact with the inner walls of the first-class extrusion holes 206.

[0043] In this embodiment: when in use, the operator places the clamp 1 flat on the ground, and holds two cables that need to be connected and places them on both sides of the clamp 1. At the same time, the outer skin of the cable is peeled off, and the wire cores inside the cable are arranged in order. The wire cores with the same wire sequence are inserted from both ends of the clamp 1, so that the wire cores pass through the ring cutting knife 204 on the side of the threading plate 201 and the type of extrusion hole 206 inside the extrusion plate 205 in turn, and the cable body is fixed by the fixing mechanism 4. At this time, the operator rotates the type of rotating shaft 202 through the external wrench, and the type of rotating shaft 202 will drive the threading plate 201 through the first thread groove 203, so that the threading plate 201 drives several ring cutting knives 204 and a first screw thread groove 203. The knife 204 moves toward the inside of a type of extrusion hole 206. While moving, the circular cutting knife 204 will squeeze the inner wall of a type of extrusion hole 206, thereby shrinking and clamping the outer surface of the wire core. As a type of rotating shaft 202 continues to push the threading plate 201 and the circular cutting knife 204 to move, the circular cutting knife 204 will cut off the skin of the wire core and push the skin and the wire core to peel off; wherein, a damping cylinder 207 is fixed at the end of each circular cutting knife 204, and the damping cylinder 207 passes through the inside of the threading plate 201. The wire core needs to pass through the damping cylinder 207 before it can pass through the circular cutting knife 204 in turn. At the same time, the damping cylinder 207 will increase the friction force on the wire core, thereby ensuring the stability of the wire core.

[0044] Furthermore, a positioning film 210 is adhered to one side of the extrusion plate 205 away from the threading plate 201. When the wire core passes through the ring cutter 204 on the side of the threading plate 201 and the type of extrusion hole 206 inside the extrusion plate 205 in turn, the wire core will be squeezed and contacted with the positioning film 210, thereby being shielded by the positioning film 210, which is convenient for operators to position the insertion length of the wire core; and when the ring cutter 204 is inserted into the type of extrusion hole 206, the positioning film 210 will be punctured, thereby not affecting the subsequent extension of the wire core; at the same time, an inner recess 208 is provided at the end of each ring cutter 204, Each type of extrusion hole 206 is provided with a convex part 209 inside, and the inner recess 208 and the convex part 209 are snap-connected. The circular cutting knife 204 entering the type of extrusion hole 206 will be squeezed and contacted with the convex part 209, thereby shrinking until the convex part 209 is snapped into the inner recess 208. At this time, the circular cutting knife 204 that has lost the extrusion restriction will reset and bounce. While bouncing, the end of the circular cutting knife 204 has extended out of the positioning membrane 210, and the positioning membrane 210 will be further expanded by the bounce, thereby preventing the outer skin cut off the wire core from being blocked in the type of extrusion hole 206.

[0045] In the above scheme, in order to complete the connection of several groups of wire cores after the outer sheaths are stripped, the specific operations are as follows.

[0046] Reference Figure 3 to Figure 4 , Figure 7In a preferred embodiment, the connection mechanism 3 also includes a back plate 303 fixedly connected to the side of each extrusion plate 205, and a plurality of evenly distributed second-class extrusion holes 304 are opened inside the back plate 303, and the inner diameters of the two ends of the second-class extrusion holes 304 are different, forming a trumpet-shaped structure, and a central plate 305 is fixedly installed inside the clamp 1, and a plurality of wire pressing rings 306 are installed inside the central plate 305, and the second-class extrusion holes 304 are pressed and contacted with the ends of the wire pressing rings 306, and the number of the first-class extrusion holes 206, the second-class extrusion holes 304 and the wire pressing rings 306 are the same and are correspondingly distributed in the horizontal direction.

[0047] In this embodiment: after completing the stripping process on the end of the wire core, the user rotates the second type of rotating shaft 301 through the external wrench, and the rotating second type of rotating shaft 301 will drive the extrusion plate 205 through the second thread groove 302, causing the extrusion plate 205 to slowly move in the center, and at the same time, the fixing mechanism 4 will drive the two cables to move in the center, causing the wire core to move in the center and be correspondingly inserted into the interior of several wire pressing rings 306. At this time, the squeezing plate 205 that continues to move will synchronously drive the back plate 303, and the back plate 303 will be squeezed on the end of the wire pressing ring 306 through the trumpet-shaped second type of extrusion hole 304, thereby causing the end of the wire pressing ring 306 to deform and shrink and clamped on the stripped end of the wire core, completing the docking of the wire cores with the same wire sequence.

[0048] In the above scheme, in order to ensure the stability of the cable connection, the specific operations are as follows.

[0049] Reference Figures 1 to 4 In a preferred embodiment, the fixing mechanism 4 includes third thread grooves 401 symmetrically opened at both ends of the second type rotating shaft 301, and the outer side of each third thread groove 401 is threadedly connected to a clamp 402 for fixing the cable, and the clamp 402 is horizontally distributed at both ends of the clamp 1.

[0050] In this embodiment: the operator arranges the wire core sequence inside the cable, and the wire cores of the same wire sequence are correspondingly inserted from the two ends of the clamp 1 into the wire stripping mechanism 2 inside the clamp 1. At this time, the operator needs to drive the clamp 402 to contract by tightening the nut, and the contracted clamp 402 will fix the cable; and after completing the stripping process on the end of the wire core, the user rotates the second type of rotating shaft 301 through the external wrench, and the rotating second type of rotating shaft 301 will drive the extrusion plate 205 through the second thread groove 302, causing the extrusion plate 205 to slowly move in the center, and at the same time, the rotating second type of rotating shaft 301 will synchronously drive the clamp 402 to move in the center through the third thread groove 401, and the moving clamp 402 will synchronously pull the cable, so that the wire core at the end of the cable is synchronously moved in the center and inserted into the wire pressing ring 306, and when the wire core is inserted into the wire pressing ring 306, the clamp 402 will move to the extreme position of the third thread groove 401, and the clamp 402 cannot move further.

[0051] Among them, it is necessary to supplement that: a positioning rod 403 is horizontally fixed at both ends of the clamp 1, and the positioning rod 403 slides through the clamp 402 at the same end, ensuring that when the clamp 402 is driven by the third thread groove 401, it will be simultaneously restricted by the positioning rod 403, so that it cannot rotate and slide along the outer side of the second type of rotating shaft 301.

[0052] Working principle: When in use, the operator places the clamp 1 flat on the ground, and holds two cables to be connected and places them on both sides of the clamp 1 (in the clamp 402). At the same time, the cable skin is peeled off, and the wire cores inside the cable are arranged in sequence. The wire cores with the same sequence are inserted from both ends of the clamp 1, so that the wire cores pass through the ring cutting knife 204 on the side of the threading plate 201 and a type of extrusion hole 206 inside the extrusion plate 205 in turn. At the same time, the operator needs to drive the clamp 402 to shrink by screwing the nut, and the shrinking clamp 402 will fix the cable (the specific state is as follows: Figure 8 As shown); at this time, the operator rotates the first type of rotating shaft 202 through the external wrench, and the first type of rotating shaft 202 will drive the threading plate 201 through the first thread groove 203, so that the threading plate 201 drives a plurality of ring cutting knives 204 to move toward the inside of the first type of extrusion hole 206. While moving, the ring cutting knife 204 will squeeze the inner wall of the first type of extrusion hole 206, thereby shrinking and clamping the outer surface of the wire core. At this time, the end of the ring cutting knife 204 has cut into the skin of the wire core. As the first type of rotating shaft 202 continues to push the threading plate 201 and the ring cutting knife 204 to move, the ring cutting knife 204 will cut off the skin of the wire core and push the skin and the wire core to peel off (the specific state is as shown in the figure). Fig. 9After the stripping process of the wire core end is completed, the user rotates the second type of rotating shaft 301 through the external wrench, and the rotating second type of rotating shaft 301 drives the extrusion plate 205 through the second thread groove 302, causing the extrusion plate 205 to slowly move in the center, and at the same time, the rotating second type of rotating shaft 301 synchronously drives the clamp 402 to move in the center through the third thread groove 401, and the moving clamp 402 synchronously pulls the cable, so that the wire core at the end of the cable synchronously moves in the center and is inserted into the inside of the wire pressing ring 306 (the specific state is as shown in FIG. Fig.10 As shown), and when the wire core is inserted into the wire pressing ring 306, the clamp 402 will reach the limit position of the third thread groove 401, and the clamp 402 cannot move further; at this time, the squeezing plate 205 that continues to move will synchronously drive the back plate 303, and the back plate 303 will squeeze the end of the wire pressing ring 306 through the trumpet-shaped second type squeezing hole 304, so that the end of the wire pressing ring 306 is deformed and contracted and clamped on the stripped end of the wire core, completing the docking of the wire cores with the same wire sequence (the specific state is as shown in FIG. Fig.11 shown).

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
