Description

Technical Field

[0001] The present invention relates to a feeding device, and in particular to a cable self-adaptive clamping and feeding device. Background Art

[0002] High-voltage cables are an important part of urban power distribution systems. They can effectively save line corridors and reduce the impact of environmental factors, and their proportion in many urban power distribution networks is increasing continuously. Since the manufacturing length of a single cable is generally limited, during the installation, maintenance, and laying of cables, intermediate joints are essential and in huge demand. Currently, cable joints are mainly made manually on-site, and the construction quality has become the main hidden danger for the operation of cable lines. During the production of cable joints, it is easily affected by the surrounding environment, the skills of construction workers, the construction period, etc., leaving various minor defects on the cable joints. According to statistics, more than 63% of high-voltage cable failures are related to the quality of cable stripping and processing. The lack of effective monitoring means and low intelligence in the high-voltage cable stripping process have become the most prominent contradictions affecting the cable stripping quality. Therefore, innovating construction tools, improving processing accuracy, and realizing the intelligence and monitorability of stripping tools have become difficult problems that engineers must overcome.

[0003] Currently, when making intermediate joints and terminal heads of high-voltage cables, it is necessary to strip and / or polish the insulation shielding layer of the high-voltage cable at the intermediate joint and terminal head of the cable. The existing method for stripping and / or polishing the intermediate joint and terminal head of the cable is to manually insert the cable to be polished into the stripping and / or polishing mechanism for polishing. However, when manually inserting the cable to be polished into the stripping and / or polishing mechanism, due to different subjective judgments of people, the lengths of different cables inserted into the stripping and / or polishing mechanism are different, which will make it difficult to control the precision and quality of wire stripping during the cable glass fiber process.

[0044] Please refer to Figure 1-8 As shown, those skilled in the art should understand that in the disclosure of the present invention, the orientation or positional relationship indicated by terms such as "upper", "lower", "one end", "the other end", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting the present invention.

[0045] It should be noted that currently, when manufacturing medium joints and terminal heads of high-voltage cables, it is necessary to strip and / or polish the insulation shielding layer of the high-voltage cable at the medium joint and terminal head of the cable. The existing method for stripping and / or polishing the medium joint and terminal head of the cable is to manually insert the cable to be polished into the stripping and / or polishing mechanism for polishing. However, when manually inserting the cable to be polished into the stripping and / or polishing mechanism, due to different subjective judgments of people, the lengths of different cables inserted into the stripping and / or polishing mechanism are different, which will make it difficult to control the precision and quality of the cable stripping process.

[0046] Based on this, this embodiment provides a cable adaptive clamping and feeding device, including:

[0047] A feeding part 100, used for feeding the target cable, having:

[0048] A first rotating member 110, rotatably arranged in the feeding part, for conveying the target cable on the first rotating member 110;

[0049] A first measuring member 120, connected to the first rotating member 110, for measuring the rotation distance of the first rotating member 110.

[0050] When this embodiment is in use, the target cable is placed on the first rotating member 110 for transmission, and is transmitted to the corresponding stripping and / or grinding mechanism. Through the transmission of the first rotating member 110, the first measuring member 120 measures the rotation distance of the first rotating member 110. When the rotation distance of the first rotating member 110 reaches the required distance, the transmission of the target cable is stopped, so as to control the supply distance of the target cable, thereby improving the precision and quality of wire stripping.

[0051] It should be noted that the target cable is the cable to be stripped or ground; the first rotating member can be a driven wheel, and the target cable moves on the driven wheel; the first measuring member 120 can be an encoder, specifically a tachometric encoder, which is used to measure the rotation distance of the first rotating member. The rotation distance of the first rotating member 110 refers to the linear distance of the rotation on the surface of the rotating wheel.

[0052] In some embodiments, the clamping portion 200 is connected to the feeding portion 100 and is used to clamp the target cable.

[0053] While clamping the target cable, the target cable is fed.

[0054] Exemplarily, the clamping portion includes:

[0055] The first clamping members 210 are arranged in pairs. The feeding portion 100 has a second rotating member 130. Both ends of the second rotating member 130 are rotatably connected to the first clamping members 210 respectively;

[0056] The second clamping members 220 are arranged in pairs and are respectively rotatably connected to the first clamping members 210. Both ends of the first rotating member 210 are rotatably connected to the second clamping members 220 respectively.

[0057] When in use, by rotatably connecting the first clamping member 210 and the second clamping member 220, the distance between the first rotating member 110 and the second rotating member 130 can be adjusted. By clamping the target cable with the first rotating member 110 and the second rotating member 130, cables with different diameters can be clamped;

[0058] Exemplarily, the second rotating member 130 includes:

[0059] The first frustum 131, the bottom with a larger radius of the first frustum 131 is rotatably connected to one of the first clamping members 210;

[0060] The second frustum 132, and the bottom with a smaller radius of the first frustum 131 is matched and connected to the bottom with a smaller radius of the first frustum 131. The bottom with a larger radius of the second frustum 132 is rotatably connected to the other first clamping member 210;

[0061] Such as Figure 1As shown, the target cable can be clamped between the first frustum 131 and the second frustum 132, preventing the target cable from slipping off both sides of the first rotating member 110 and the second rotating member 130.

[0062] It should be noted that the first frustum 131 and the second frustum 132 can have exactly the same size and shape, enabling the target cable to be transmitted precisely in the middle of the first rotating member 110 and the second rotating member 130.

[0063] In some embodiments, the clamping portion 200 includes:

[0064] An elastic member 210, with both ends of the elastic member 210 connected to the first clamping member 210 and the second clamping member 220 respectively.

[0065] During use, the target cable can be clamped in the middle of the first clamping member 210 and the second clamping member 220 through the elastic member 210. The elastic member 210 can clamp the target cable, and at the same time, due to the action of the elastic member 210, a pulling force towards the middle can be applied to the first clamping member 210 and the second clamping member 220, enabling the target cable to be in the central position between the first clamping member 210 and the second clamping member 220, facilitating connection with subsequent stripping or grinding mechanisms.

[0066] It should be noted that the elastic member 210 can be a tension spring. As Figure 1 shown, spring fixing pins are respectively provided on the first clamping member 210 and the second clamping member 220, and both ends of the tension spring are respectively connected to the spring fixing pins. It should be noted that in Figure 1 , the upper end of the tension spring is not connected to the upper spring fixing pin; further, in order to keep the cable in the central position between the first clamping member 210 and the second clamping member 220, the elastic member 210 can be a spring with a relatively large pulling force to avoid the influence of gravity.

[0067] In some embodiments, the device provided by the present application includes:

[0068] A driving portion 300, with the driving portion 300 in transmission connection with the second rotating member 130 for driving the second rotating member 130 to rotate.

[0069] By driving the second rotating member 130 to rotate through the driving portion, the target cable is driven to move accordingly. It should be noted that the driving portion 300 can be a motor, and the motor is in transmission connection with the second rotating member 130 through a transmission belt or gears. As Figure 1 shown, a transmission belt connection is adopted.

[0070] In some embodiments, the device provided by the present application includes:

[0071] The supporting part 500 is connected to the connection parts of the first clamping part 210 and the second clamping part 220 at both ends respectively.

[0072] The supporting part 500 is used to support the first clamping part 210 and the second clamping part 220. The supporting part can adopt a support frame, such as Figure 1 , Figure 2 As shown, the target cable can pass between the support frames.

[0073] In some embodiments, the device provided by the present application includes:

[0074] The control part 400 is connected to the driving part 300 and is used to control the driving part 300, including:

[0075] The first sensing part 410 is arranged at the inlet of the feeding part 100 and is connected to the driving part 300, and is used to control the driving part 300;

[0076] The second sensing part 420 is arranged at the outlet of the feeding part 100 and is connected to the first measuring part, and is used to control the first measuring part.

[0077] During use, after the first sensing part 410 senses the target cable entering at the inlet, it starts the driving part 300 to drive the second rotating part 130 to rotate, and then drives the target cable to be conveyed; after the second sensing part 420 senses the target cable coming out, it controls the first measuring part 100 to open and starts to measure the rotation distance of the first rotating part 110. Generally, after the target cable comes out from the outlet of the feeding part, it will directly enter the stripping or grinding mechanism. Therefore, the distance measured by the first measuring part is the stripping or grinding distance of the cable.

[0078] It should be noted that both the first sensing part 410 and the second sensing part 420 can adopt infrared sensors.

[0079] In some embodiments, the clamping part 200 includes:

[0080] The first driving part 230,

[0081] The third rotating part 240 is rotationally connected to the first driving part 230 and is arranged between the first clamping part 210 and the second clamping part 220 on one side. When the third rotating part 240 rotates to a certain angle, the first clamping part 210 and the second clamping part 220 are opened. When the third rotating part 240 rotates to a certain angle, the first clamping part 210 and the second clamping part 220 are closed;

[0082] When the target cable needs to enter the first rotating member and the second rotating member, rotate the third rotating member 240. The first clamping member 210 and the second clamping member 220 are opened, so that the cable enters between the first rotating member and the second rotating member. Then continue to rotate the third rotating member 240, and the first clamping member 210 and the second clamping member 220 are closed, clamping the target cable therebetween. Due to the existence of the elastic member, the target cable is clamped in the middle of the first clamping member and the second clamping member. It should be noted that the first driving member 230 can adopt a cam motor. When connected to the third rotating member 240, the middle part of the third rotating member 240 is connected to the cam motor. Specifically, when connecting, it can be welded or connected by a coupling. The first driving member can be connected to the lower clamping member or the upper clamping member. Specifically, when connecting, it can be connected by screws, which is not limited herein. For example Figure 2 as shown, it is connected to the lower clamping member.

[0083] Exemplarily, the third rotating member 240 includes:

[0084] The first rotating sub-member 241, which is rectangular, has its middle part connected to the rotating shaft of the first driving member 230, is arranged between the first clamping member 210 and the second clamping member 220 on one side, and the first clamping member 210 and the second clamping member 220 have limiting surfaces at the position of the first sub-rotating member 241;

[0085] The cam followers 242, with two in number, are respectively arranged at both ends of the first rotating sub-member 241 and cooperate with the limiting surfaces.

[0086] For example Figure 6 、 Figure 7 as shown, when it is necessary to separate the first rotating member and the second rotating member, start the first driving member to rotate the first rotating sub-member until the two long sides contact the limiting surfaces at both ends. The cam followers 242 support the limiting surfaces, and the first rotating member and the second rotating member open, enabling the target cable to enter. After the target cable enters, rotate the first rotating sub-member 241 by 90 degrees, and the first rotating member and the second rotating member clamp the target cable under the action of the elastic member's pulling force.

[0087] The above-described embodiments are only descriptions of the preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
