Description

Technical Field

[0001] This invention relates to the field of wire stripping equipment technology, and in particular to a stripping device for testing the performance of alloy outer sheaths of through-ground wires, which is mainly used in the key step of efficiently stripping the outer copper foil in the testing process. Background Technology

[0002] With the rapid development of my country's high-speed railway network, the grounding requirements for various equipment and facilities are becoming increasingly stringent to further ensure the safety of the high-speed railway system and personnel. my country's high-speed railways employ a comprehensive grounding system that involves laying a continuous grounding wire along the railway line and connecting the grounding networks of all facilities along the line into a unified system. In modern railway systems, the continuous grounding wire is a crucial facility for ensuring the safety of railway communication, signaling, and electrical systems, and its reliability is paramount. The continuous grounding wire is the grounding conductor connecting the traction power supply return current, power supply, signaling, communication, and other electronic information systems and various equipment along the railway line. Its alloy outer sheath possesses excellent corrosion resistance and environmental performance.

[0003] Currently, copper stripping in engineering mainly relies on operators using manual tools or angle grinders for stripping. This method has significant drawbacks: First, manual operation is inefficient and cannot meet the needs of batch testing; second, the cutting depth depends entirely on experience, which easily damages the internal stranded cores, not only destroying the conductor's integrity but also leading to inaccurate subsequent sheath thickness measurements; third, manual operation has poor safety, low consistency, and poor repeatability of test results. Therefore, there is an urgent need for an efficient and accurate copper stripping device to improve the overall quality of the testing process. Summary of the Invention

[0004] The purpose of this invention is to provide a stripping device for testing the performance of alloy outer sheaths that penetrate ground wires, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A stripping device for testing the performance of an alloy outer sheath through a ground wire, comprising:

[0007] The drive module includes an output motor and a transmission mechanism driven by the output motor;

[0008] A clamping and rotating module, connected to the transmission mechanism, is used to clamp and rotate the sample to be tested;

[0009] The core positioning module is located on the side of the clamping and rotating module, and includes at least a pair of relatively movable auxiliary wire wheels and a first adjustment mechanism for driving the relative movement of the pair of auxiliary wire wheels, for clamping and positioning the sample core of the sample to be tested during the stripping process.

[0010] The peeling module includes a peeling knife and a second adjustment mechanism for adjusting the cutting depth of the peeling knife, wherein the cutting edge of the peeling knife is aligned with the sample outer alloy copper sheet of the sample to be tested, which is fixed by the clamping and rotating module.

[0011] The drive module, clamping and rotating module, wire core positioning module and stripping module work together to achieve the spiral removal of the copper alloy coating on the sample by rotating the sample and radially cutting into it with the stripping knife.

[0012] The clamping and rotating module includes a sample clamping plate, which is a three-jaw chuck.

[0013] The transmission mechanism is a synchronous belt drive system. The driven wheel of the synchronous belt drive system is coaxially connected to the sample clamping plate, and the center of the sample clamping plate is provided with a through hole for the sample to be tested to pass through.

[0014] The at least one pair of auxiliary wire pulleys in the core positioning module includes an upper wire pulley and a lower wire pulley, and the first adjustment mechanism includes an upper wire pulley adjustment nut and a lower wire pulley adjustment nut that are respectively connected to the upper wire pulley and the lower wire pulley.

[0015] The upper and lower thread-laying reels are rollers with anti-slip textures on their surfaces.

[0016] The peeling module also includes a sampling blade disc for mounting the peeling knife, which is fixedly disposed on one side of the clamping and rotating module.

[0017] The second adjustment mechanism is a peeling knife adjusting nut, used to adjust the radial position of the peeling knife on the sampling knife disc.

[0018] The peeling knife is a detachable carbide blade.

[0019] The cutting depth of the peeling knife is configured to be less than or equal to the thickness of the copper alloy foil covering the sample.

[0020] It also includes a frame, on which the drive module, clamping and rotating module, wire core positioning module and stripping module are all mounted.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0022] 1) This invention mechanizes the peeling process by using an output motor to drive the sample clamping disc, which in turn rotates the sample to be tested. This rotation, combined with a peeling blade, achieves a much higher efficiency than manual operation. Furthermore, the peeling blade's adjusting nut allows for precise control of the cutting depth, ensuring that only the outer copper alloy sheath is removed without damaging the sample's core. This provides a non-destructive, high-quality sample for subsequent thickness measurements, fundamentally guaranteeing the accuracy of the test data.

[0023] 2) The present invention is equipped with a core positioning module consisting of upper and lower wire-laying wheels and their adjusting nuts. During the stripping process, the core can be firmly clamped and positioned, effectively preventing sample shaking and ensuring the stability of the stripping process. The entire operation process keeps the operator away from the blade, reducing safety risks. At the same time, the modular design makes the device compact, the operation process simple, and easy to promote and use on site.

[0024] 3) The sample clamping disc in this invention has a good clamping range and can adapt to through-ground wires of different diameters. The mechanized operation mode eliminates human interference, ensuring that the length, depth, and cut quality of each peeling are consistent, greatly improving the repeatability and comparability of the test results.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0030] like Figure 1-2As shown, this invention provides a stripping device for testing the performance of alloy outer sheaths with through-ground wires, including a frame, a drive module, a clamping and rotating module, a wire core positioning module, and a stripping module. The drive module includes an output motor 1 and a transmission mechanism 2 driven by the output motor 1. The transmission mechanism 2 is a synchronous belt drive system. The clamping and rotating module is connected to the transmission mechanism 2 and is used to clamp and rotate the sample 4 to be tested. The clamping and rotating module includes a sample clamping plate 3, which is a three-jaw chuck. The driven wheel of the synchronous belt drive system is connected to the sample clamping plate 3 via a rotating spindle. Both the rotating spindle and the sample clamping plate 3 have coaxial through holes at their centers, forming a passage for the sample 4 to be tested.

[0031] The core positioning module is located on one side of the clamping and rotating module, and includes at least one pair of relatively movable auxiliary threads and a first adjustment mechanism for driving the relative movement of the pair of auxiliary threads, used to clamp and position the sample core 13 of the sample 4 to be tested during the stripping process. The at least one pair of auxiliary threads in the core positioning module includes an upper thread-laying wheel 10 and a lower thread-laying wheel 11, which are rollers with anti-slip textures on their surfaces; the first adjustment mechanism includes an upper thread-laying wheel adjusting nut 6 and a lower thread-laying wheel adjusting nut 9, which are respectively connected to the upper thread-laying wheel 10 and the lower thread-laying wheel 11. The upper thread-laying wheel adjusting nut 6 and the lower thread-laying wheel adjusting nut 9 are used to adjust the distance between the upper thread-laying wheel 10 and the lower thread-laying wheel 11 and the surface of the sample 4 to be tested, so as to clamp the sample core 13 and prevent it from moving.

[0032] The peeling module includes a sampling blade disc 5, a peeling blade 7, and a second adjustment mechanism for adjusting the cutting depth of the peeling blade 7. The cutting edge of the peeling blade 7 is aligned with the sample outer alloy copper foil 12 of the sample to be tested 4, which is fixed by the clamping and rotating module. The sampling blade disc 5 is fixedly mounted on one side of the clamping and rotating module for mounting the peeling blade 7. The second adjustment mechanism is a peeling blade adjusting nut 8, which is threaded onto the sampling blade disc 5 and connected to the peeling blade 7, for adjusting the radial position of the peeling blade 7 on the sampling blade disc 5. In this embodiment, the peeling blade 7 is a detachable carbide blade, and the cutting depth of the peeling blade 7 is configured to be less than or equal to the thickness of the sample outer alloy copper foil 12, ensuring that only the sample outer alloy copper foil 12 is cut without touching the sample core 13.

[0033] The drive module, clamping rotation module, wire core positioning module, and stripping module work together to achieve the spiral removal of the copper alloy foil 12 covering the sample by rotating the sample 4 and radially cutting into it with the stripping blade 7. The output motor 1 is mounted at one end of the upper surface of the frame. The upper surface of the frame is also provided with two sets of opposing brackets for mounting the clamping rotation module and the stripping module. The top of the brackets has through holes adapted to the sample wire core 13. The clamping rotation module and the stripping module are arranged opposite each other. The clamping rotation module and the transmission mechanism 2 are located on both sides of the same bracket. The drive wheel of the transmission mechanism 2 is connected to the output motor 1 through a reducer.

[0034] In operation, the present invention fixes the sample 4 to be tested on the sample clamping plate 3. By adjusting the upper wire sheave adjusting nut 6 and the lower wire sheave adjusting nut 9, the upper wire sheave 10 and the lower wire sheave 11 clamp the sample wire core 13. Then, the stripping knife adjusting nut 8 is adjusted so that the stripping knife 7 is aligned with the sample's outer alloy copper foil 12, and the cutting depth is adjusted so that it just cuts the sample's outer alloy copper foil 12 without damaging the sample wire core 13. The output motor 1 is started, which drives the sample clamping plate 3 and the sample 4 to be tested to rotate through the transmission synchronous belt 2. The stripping knife 7 cuts the sample's outer alloy copper foil 12 and completes the stripping for subsequent testing.
