Description

Technical Field

[0001] The present invention relates to the technical field of cable sampling inspection, and specifically provides a cable sampling inspection and sampling device. Background Art

[0002] The statements in this part only provide background technical information related to the present invention, and do not necessarily constitute prior art.

[0003] A large number of cables are used in power engineering, and various specifications and models of cables need to be sampled before use. During the sampling process, sampling is required according to a certain percentage based on the specifications, models, and quantities of the cables.

[0004] In the existing sampling process, a set length of cable needs to be pulled out from the cable reel, and a cutting pliers is used to cut out a sample cable of a set length. After sampling, it is also necessary to remove the original manufacturer information and specification model marked on the cable to avoid interfering with the subsequent inspection process. As the cable model changes, the diameter, length, and weight change greatly. Some large-diameter cables are heavy, and the current manual sampling method is inefficient; at the same time, the method of removing the cable surface information after sampling is mainly manual grinding, which will damage the insulating layer of the cable outer skin and lead to inaccurate subsequent inspection results. Summary of the Invention

[0005] In order to solve at least one of the technical problems in the above background art, the present invention provides a cable sampling inspection and sampling device. The device uses a sliding clamp block driven by a screw on a base plate to clamp the cable. After pulling the cable a set length, a sample cable of a set length is obtained by a cutting component on the base plate. After the sliding clamp block resets, it runs again to send the sample cable into a spraying component to remove the information on the surface of the sample cable, and at the same time, a label is attached for the subsequent inspection process.

[0006] To achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A first aspect of the present invention provides a cable sampling inspection and sampling device, including a base plate with a wire groove on its upper surface. A cutting component and a spraying component are connected to the top of the wire groove. The cutting component and the spraying component are respectively located at both ends of the wire groove. A sliding clamp block that slides along the direction of the wire groove is provided on the side of the cutting component facing the spraying component. A screw is sleeved on the side of the sliding clamp block, and the screw is connected to a driving component; a font recognition component is provided on the side of the spraying component facing the cutting component, and a post-processing component is provided on the side away from the cutting component.

[0008] The sliding clamp block is movably connected to the screw. The driving component drives the screw to rotate, driving the sliding clamp block to slide along the direction of the wire groove. The screw is parallel to the wire groove; two groups of clamping plates arranged side by side are provided at the bottom of the sliding clamp block, and the two groups of clamping plates are close to the inner wall of the wire groove; when the cable enters the wire groove, the two clamping plates approach each other according to a control command to clamp and fix the cable.

[0009] Inside the sliding clamp block, there are two sets of telescopic rods with opposite moving ends. The telescopic rods are both connected to a set of clamping plates. The moving ends of the two telescopic rods extend or retract synchronously, enabling the clamping plates to clamp or release the cable in the cable trough.

[0010] The cutting assembly includes a housing connected to the top of the cable trough and a cutting knife that moves up and down vertically. When the cutting knife descends, it extends into the cable trough, and the cutting assembly operates according to a control command to cut the cable.

[0011] The cutting assembly includes a hydraulic arm connected inside the housing and a cutting knife connected to the moving end of the hydraulic arm.

[0012] The font recognition component has an image acquisition module arranged towards the cable trough. By obtaining the surface image of the cable in the cable trough, it recognizes the font of the cable and causes the spraying assembly to operate.

[0013] The spraying assembly includes a nozzle arranged towards the inside of the cable trough and a cleaning pump connected to the nozzle. The cleaning pump is connected to a storage tank; when the cleaning pump operates, it sprays the cleaning liquid in the storage tank onto the surface of the cable inside the cable trough.

[0014] The post - processing component includes a wiping module and a marking module.

[0015] The wiping module includes sponge blocks arranged oppositely on both sides of the inner wall of the cable trough, and the gap between the two sponge blocks is not greater than the diameter of the cable.

[0016] Compared with the prior art, the above one or more technical solutions have the following beneficial effects:

[0017] 1. The sliding clamp block carries the cable through two reciprocating motions to achieve the cable sampling + font removal operation, improving the operation efficiency of cable sampling and font removal in a semi - automatic or automatic manner.

[0018] 2. It can replace manual sampling. The cutting assembly replaces manual use of cutting pliers and cuts the cable by hydraulic means. For large - diameter cables, the cutting efficiency is better, and the complete cut is beneficial for subsequent appearance dimension inspection.

[0019] 3. The spraying assembly uses the cleaning liquid to clean the original information on the cable surface, and cooperates with the sponge blocks in the post - processing component to further remove the original information on the cable surface by physical friction, reducing the loss of the cable insulation layer in the traditional method.

[0020] 4. The length of cable sampling can be determined by controlling the movement stroke of the sliding clamp block, eliminating the need for traditional manual use of a scale, with higher efficiency. Description of the Drawings

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] It should be noted that the following detailed descriptions are all exemplary and are intended to provide a further description of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs.

[0026] It should be noted that the terms used herein are only for describing specific implementation manners and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0027] As described in the background art, in the existing sampling process, a set length of cable needs to be pulled out from the cable reel, and a cutting pliers is used to cut out a sample cable of a set length; some cables with large diameters are heavy, and the current manual sampling method is inefficient.

[0028] After sampling, it is also necessary to remove the original manufacturer information and specification models marked on the cable to avoid interfering with the subsequent inspection process. The method of removing the cable surface information is mainly manual polishing, which will damage the insulation layer of the cable outer skin and cause inaccurate subsequent inspection results.

[0029] Therefore, the following embodiments provide a cable sampling and inspection device. The cable is clamped by a sliding clamp block driven by a screw installed on a base plate. After pulling the cable a set length, a sample cable of a set length is obtained by using a cutting component on the base plate. After the sliding clamp block resets, it runs again to send the sample cable into the spraying component to remove the information on the surface of the sample cable and at the same time label it for the subsequent inspection process.

[0030] Embodiment 1:

[0031] As Figure 1 shown, the purpose of this embodiment is to provide a wire and cable sampling device for random inspection, including:

[0032] A base plate with a wire groove 3 on its upper surface. The top of the wire groove 3 is connected to a cutting assembly 7 and a spraying assembly 9. The cutting assembly 7 and the spraying assembly 9 are respectively located at both ends of the wire groove 3. A sliding clamping block 6 that slides along the direction of the wire groove 3 is provided on one side of the cutting assembly 7 facing the spraying assembly 9. A screw rod 4 is sleeved on the side of the sliding clamping block 6, and the screw rod 4 is connected to a driving assembly 5; A font recognition assembly 8 is provided on one side of the spraying assembly 9 facing the cutting assembly 7, and a post-processing assembly 10 is provided on the side away from the cutting assembly 7.

[0033] The sliding clamping block 6 is movably connected to the screw rod 4. The driving assembly 5 drives the screw rod 4 to rotate, driving the sliding clamping block 6 to slide along the direction of the wire groove 3. The screw rod 4 is parallel to the wire groove 3; Two groups of clamping plates are arranged side by side at the bottom of the sliding clamping block 6. The two groups of clamping plates are close to the inner wall of the wire groove 3. When the wire and cable 2 enters the wire groove 3, the two clamping plates approach each other according to the control command to clamp and fix the wire and cable 2, thereby driving the wire and cable 2 to move along the direction of the wire groove 3 following the sliding clamping block 6.

[0034] In this embodiment, the sliding clamping block 6 internally has two groups of electric telescopic rods or pneumatic telescopic rods with opposite moving ends. The telescopic rods are both connected to a group of clamping plates. When receiving an instruction, the moving ends of the two telescopic rods extend or retract synchronously, so that the clamping plates can clamp or release the wire and cable 2 in the wire groove 3.

[0035] In this embodiment, the driving assembly 5 can be a motor. The output shaft of the motor drives the screw rod 4 to rotate. Since the screw rod 4 is parallel to the wire groove 3, when the sliding clamping block 6 is driven by the rotating screw rod 4 to move along the direction of the wire groove 3, the wire groove 3 plays the role of a guide rail.

[0036] The cutting assembly 7 includes a housing connected to the top of the wire groove 3 and a cutting knife that moves up and down in the vertical direction. When the cutting knife descends, it extends into the wire groove 3. The cutting assembly 7 operates according to the control command to cut the wire and cable 2.

[0037] In this embodiment, the cutting assembly 7 can be a hydraulic arm connected inside the housing and a cutting knife connected to the moving end of the hydraulic arm. The hydraulic arm is connected to an external hydraulic station or a hydraulic pump inside the housing to obtain hydraulic power to perform the cutting action.

[0038] The font recognition assembly 8 has an image acquisition module arranged facing the wire groove 3. The image acquisition module can be a camera or a camera. By acquiring the surface image of the wire and cable 2 in the wire groove 3, the font of the wire and cable 2 is recognized, so that the spraying assembly 9 operates.

[0039] In this embodiment, the font refers to the manufacturer information and cable specification model information marked on the cable surface. During sampling, this part of the information should be removed so that subsequent inspection operations can directly test the appearance size data of the cable without knowing the cable information, such as the insulation layer thickness, the number of cores, the effective cross-sectional area of the core conductor, and the core braiding method, etc. The information obtained from the detection is compared with the information originally marked on the cable (i.e., the specification model on the cable surface). If they match, the cable meets the requirements; if not, it indicates that the cable may be falsely marked and needs to be reinspected.

[0040] In this embodiment, it is a known technology to identify the font on the cable surface using image information, which will not be elaborated in this embodiment.

[0041] The spraying component 9 includes a spray head arranged towards the inside of the wire groove 3 and a cleaning pump connected to the spray head. The cleaning pump is connected to the storage tank. When the font recognition component 8 recognizes that there is a font on the cable 2 in the wire groove 3, the cleaning pump operates to spray the cleaning liquid in the storage tank onto the surface of the cable 2 inside the wire groove 3 to remove the manufacturer information and cable specification model information marked on the surface of the cable 2.

[0042] In this embodiment, the storage tank can be arranged in an area far from the base plate and connected to the cleaning pump through a pipeline.

[0043] In this embodiment, the cleaning liquid is a liquid that can remove the font information on the cable 2 surface. The font information is usually paint, so the cleaning liquid can be a common organic solvent.

[0044] The post-processing component 10 includes a wiping module and a marking module.

[0045] The wiping module includes sponge blocks arranged oppositely on both sides of the inner wall of the wire groove 3. The gap between the two sponge blocks is not greater than the diameter of the cable 2. After the cable 2 is sprayed with the cleaning liquid, the font information that can be removed is limited, and physical friction is still required to completely remove it. Then, the cable 2 drives relative movement with the two sponge blocks under the drive of the sliding clamp block 6 to form physical friction to further remove the remaining font information.

[0046] The marking module connects an electronic tag or a paper tag to the cable 2. The information in the tag can be a set serial number, which is used to associate the sampling time and sampling length information of the cable 2. During subsequent inspection processes, it is associated with the detected information of the cable 2 and finally associated with the original specification model information of the cable 2. The output detection information and the original information are both associated with the serial number, which is beneficial for subsequent comparison of the two parts of information to determine whether the cable 2 meets the requirements.

[0047] In this embodiment, the marking module can be an existing device.

[0048] The working process of the above device is as follows:

[0049] Before sampling, the cable 2 is wound around the cable reel 1;

[0050] The sliding clamp block 6 is in the initial position (in this embodiment, the initial position is at one end of the wire groove 3 and fits with the cutting assembly 7). One end of the cable 2 is inserted into the wire groove 3 and extends along the direction of the wire groove 3 to the lower part of the sliding clamp block 6;

[0051] The sliding clamp block 6 acts to clamp the cable 2. According to the sampling requirement, the driving assembly 5 is controlled to rotate a set number of turns, so that the screw rod 4 drives the sliding clamp block 6 to move a set distance along the direction of the wire groove 3, and this set distance is the required sampling length of the cable 2;

[0052] After reaching the required length, the sliding clamp block 6 stops running, and the cutting assembly 7 acts to cut off the cable 2. At this time, the sliding clamp block 6 carries the head end of the cable 2, and the cutting assembly 7 is located at the tail end of the cable 2. The required sample cable is between the two;

[0053] The sliding clamp block 6 resets, the clamping plate loosens, and after returning to the initial position along the wire groove 3, the clamping plate acts again to clamp the tail end of the cable and execute the previous movement direction, that is, carry the tail end of the cable 2 and push the cable 2 along the wire groove 3 into the wire groove 3 where the spraying assembly 9 is located; [[ID=!13]]

[0054] The head end of the cable 2 passes through the font recognition assembly 8, the spraying assembly 9 and the post-processing assembly 10 in sequence. After recognizing the font on the surface of the cable 2, the spraying assembly 9 acts to spray the cleaning liquid onto the surface of the cable 2 to remove the font. The sponge block in the post-processing assembly 10 further removes the font on the surface of the cable 2 by physical friction. Finally, after labeling and separating from the wire groove 3, the clamping plate of the sliding clamp block 6 separates and returns to the initial position, preparing for the next sampling.

[0055] The above device realizes the cable sampling + font removal operation by the sliding clamp block carrying the cable through two reciprocating motions, and improves the operation efficiency of cable sampling and font removal in a semi-automatic or automatic manner.

[0056] It can replace manual sampling. The cutting assembly replaces manual use of cutting pliers and cuts the cable by hydraulic means. For large-diameter cables, the cutting efficiency is better, and the complete cut is beneficial to subsequent appearance dimension inspection.

[0057] The spraying assembly uses the cleaning liquid to clean the original information on the surface of the cable, and cooperates with the sponge block in the post-processing assembly to further remove the original information on the surface of the cable by physical friction, reducing the loss of the cable insulation layer in the traditional way.

[0058] The sampling length of the cable can be determined by controlling the movement stroke of the sliding clamp block, and there is no need for traditional manual use of a scale, which is more efficient.

[0059] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
