Description

Technical Field

[0001] This utility model relates to the field of conductor manufacturing technology, specifically to a jumper detection device for transposed conductors. Background Technology

[0002] Transposed conductors are a key material in power equipment manufacturing, made by winding multiple enameled flat wires arranged in a specific pattern of alternation. During manufacturing, multiple insulated flat wires are connected in parallel and periodically exchanged during winding, ensuring that each conductor is evenly distributed in a magnetic field. This structure effectively balances the induced electromotive force of each conductor, significantly reducing circulating current losses and eddy current losses in transformer windings, thus improving equipment efficiency. Simultaneously, its compact design enhances the mechanical strength of the windings, optimizes heat dissipation, and saves materials and space. It is widely used in large power transformers, reactors, and other equipment, and is an important technical means to improve the stability and economy of power transmission.

[0003] During the production of transposed conductors, deformation of the enameled flat copper wire during transposition may cause skipped wires. During the transposition process, the conductor may pop out of the transposition slot and overlap two rows of conductors, or there may be errors in the transposition operation (such as processing two conductors at once or omitting a single conductor). Ultimately, this can result in localized thickness deviations in the transposed conductor, exceeding the design tolerance range. Furthermore, in subsequent use, when winding the transposed conductor, it may become incompatible with other conductor segments, causing uneven distribution and affecting the winding and arrangement of subsequent conductors, potentially even developing into serious malfunctions.

[0004] The shortcomings of existing technical solutions are as follows: Currently, jumper wire inspection is mostly carried out manually, relying primarily on visual inspection and simple measuring tools. Operators use micrometers to sample and inspect the dimensions of the transposed wires, while also observing whether the wire surface is flat and whether there are any traces of wire sticking out or clamping. However, manual inspection is inefficient, difficult to maintain continuous inspection at the machine for extended periods, and easily affected by factors such as experience and fatigue, which can lead to missed inspections. Utility Model Content

[0005] The purpose of this invention is to provide a jumper detection device for transposed wires, in order to solve the technical problem that the detection process is inefficient and potential problems are easily overlooked.

[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0007] A jumper detection device for transposed wires includes a guide mechanism. The guide mechanism includes a base, on which a lifting component is fitted. A support plate is connected to the output end of the lifting component. An orientation component is mounted on the support plate. A lateral movement component is fitted between the orientation component and the support plate to drive the orientation component to move laterally. The orientation component includes a mounting block that cooperates with the lateral movement component. Two sets of symmetrically positioned elastic telescopic members are mounted on the mounting block. A pressure sensor is mounted at the output end of each set of elastic telescopic members. A pressure plate is fixedly connected to the output end of each set of pressure sensors. The two sets of pressure plates are positioned opposite each other. A pressure roller that can rotate along the surface of the wire is rotatably connected to the pressure plate. A dragging component for clamping and dragging the wire is mounted on the mounting block. A winding machine for winding the wire is mounted on one side of the base.

[0008] As a further embodiment of this utility model: multiple sets of limiting grooves are symmetrically provided on the mounting block and arranged along the extension direction of the mounting block. Each set of limiting grooves is slidably fitted with a limiting block. A spring is connected between one side of each set of limiting blocks and the inner wall of the corresponding limiting groove. A rotating wheel is rotatably connected to each set of limiting blocks.

[0009] As a further embodiment of this utility model: the dragging assembly includes two sets of conveyor belt assemblies symmetrically arranged on the mounting block for clamping and transporting the wire.

[0010] As a further embodiment of this utility model: symmetrical drag grooves are provided on both sides of the mounting block, and a slider that slides in cooperation with the corresponding drag groove is fixedly provided at the bottom of each set of conveyor belt components. A threaded rod is rotatably connected between the two sets of drag grooves. The threads on both sides of the threaded rod are opposite in direction and are threadedly connected to the two sets of sliders.

[0011] As a further embodiment of this utility model: each set of elastic telescopic components includes an elastic telescopic rod, each set of elastic telescopic rods is fixedly connected to the mounting block, each set of elastic telescopic rods is located between the drag assembly and the rotating wheel, each set of pressure sensors is fixedly connected to the output end of the corresponding elastic telescopic rod, the lateral movement assembly includes an electric guide rail fixedly mounted on the support plate, and the mounting block is fitted onto the electric guide rail.

[0012] As a further embodiment of this utility model, the mounting block is rotatably provided with multiple sets of sliding wheels arranged along the extension direction of the mounting block to reduce the friction between the wire and the mounting block.

[0013] The beneficial effects of this utility model are:

[0014] 1. In the process of using this utility model, the wire passes between two sets of pressure plates. Pressure rollers are rotatably connected to the pressure plates to squeeze the wire. While the pressure rollers squeeze the wire, the wire also generates reverse pressure on the pressure rollers. The pressure sensor can detect the pressure transmitted by the pressure plates. When a skipped wire occurs on the surface of the wire, it will vibrate on the pressure plates. By monitoring the degree of change in the pressure on the pressure plates, the skipped wire defect can be monitored, reducing the detection cost.

[0015] 2. When placing the wire, the end of the wire can be connected to the winding roller of the winding machine. The wire is then laid out sequentially between the rotating wheels, between the pressure plates, and between the conveyor belt assembly. Rotating the threaded rod drives two sets of sliders to move, which in turn drive the conveyor belt assembly to move, thereby adjusting the spacing between the two sets of conveyor belt assemblies to accommodate wires of different diameters. The spring pushes the limiting block, which in turn drives the rotating wheel to squeeze the wire, thus correcting the wire's deviation. The elastic telescopic rod drives the pressure sensor and the pressure plate to press against both sides of the wire, limiting the wire through elastic compression. This allows the device to be applied to wires of different diameters, thereby expanding its applicability. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-4 As shown, a jumper detection device for transposed wires includes a guide mechanism 2, which includes a base 201. A lifting component 202 is mounted on the base 201. The lifting component 202 includes an electric telescopic platform. A support plate 203 is connected to the output end of the lifting component 202. A directional component 205 is mounted on the support plate 203. An electric guide rail 204 for driving the directional component 205 to move laterally is fixed between the directional component 205 and the support plate 203.

[0024] The orientation component 205 includes a mounting block 2051 that cooperates with the electric guide rail 204. The electric guide rail 204 can drive the mounting block 2051 to move laterally, thereby facilitating the uniform winding of the wire. Multiple sets of limiting grooves 2052 are symmetrically arranged on the mounting block 2051 along its extension direction. Each set of limiting grooves 2052 has a limiting block 2054 slidably fitted inside. A spring 2053 is connected to one side of each limiting block 2054 and the inner wall of the corresponding limiting groove 2052. A rotating wheel 2055 is rotatably connected to each limiting block 2054. The wire moves between the symmetrical rotating wheels 2055, which clamp and correct the wire, ensuring that the wire can be properly tested.

[0025] The mounting block 2051 is provided with two sets of symmetrical elastic telescopic rods 2056. Each set of elastic telescopic rods 2056 is fixedly connected to a pressure sensor 2058 at its output end. Each set of pressure sensor 2058 is fixedly connected to a pressure plate 2057 at its output end. The two sets of pressure plates 2057 are in corresponding positions. The wire moves between the two sets of pressure plates 2057. A pressure roller 209 that can rotate along the surface of the wire is rotatably connected to the pressure plate 2057. A winding machine 1 for winding the wire is provided on one side of the base 201.

[0026] The mounting block 2051 has symmetrical drag grooves 2059 on both sides. The mounting block 2051 has two sets of drag components 206 symmetrically arranged on it for clamping and dragging the wire. The drag component 206 includes a slider 2061 that slides in cooperation with the corresponding drag groove 2059. Each slider 2061 is rotatably connected to a conveyor belt assembly 2062. The two sets of conveyor belt assemblies 2062 cooperate with each other to clamp and position the wire, while ensuring normal detection of the wire.

[0027] A threaded rod 207 is rotatably connected between the two sets of drag grooves 2059. The threads on both sides of the threaded rod 207 are in opposite directions and are threadedly connected to the two sets of sliders 2061. By rotating the threaded rod 207, the two sets of sliders 2061 are driven to move closer or further apart, thereby realizing the clamping and transportation of wires of different diameters.

[0028] Multiple sets of sliding wheels 208 are rotatably provided on the mounting block 2051, arranged along the extension direction of the mounting block 2051, to reduce the friction between the wire and the mounting block 2051.

[0029] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of the embodiments of this solution will now be explained in conjunction with specific application scenarios:

[0030] When placing the wire, the end of the wire is connected to the winding roller of the winding machine 1. The wire is then laid out between the rotating wheels 2055, between the pressure plates 2057, and between the conveyor belt assembly 2062. The threaded rod 207 is rotated, which drives the two sets of sliders 2061 to move. The sliders 2061 drive the conveyor belt assembly 2062 to move, thereby adjusting the spacing between the two sets of conveyor belt assemblies 2062 to accommodate wires of different diameters. The spring 2053 pushes the limit block 2054, which in turn drives the rotating wheels 2055 to squeeze the wire, thereby correcting the wire's deviation. The elastic telescopic rod 2056 drives the pressure plates 2057 to press against both sides of the wire.

[0031] The winding machine 1 is started to wind the wire. During the winding process, the wire passes between two sets of pressure plates 2057. Pressure rollers 209, which can rotate along the surface of the wire, are rotatably connected to the pressure plates 2057. While the pressure rollers 209 compress the wire, the wire also generates reverse pressure on the pressure rollers 209. The pressure sensor 2058 can detect the pressure transmitted from the pressure plates 2057. When a skipped wire occurs on the surface of the wire, vibration will occur on the pressure plates 2057. This vibration is monitored by the pressure sensor 2058. The degree of change in the applied pressure is used to monitor the surface shape of the conductor. When the conductor is wound, the electric guide rail 204 will drive the mounting block 2051 to slowly and repeatedly move laterally, so that the conductor can be evenly distributed on the winding roller of the winding machine 1. With each layer of conductor wound, the winding diameter on the winding roller will increase slightly. Therefore, with each layer of conductor wound on the winding roller, the lifting component 202 will extend a certain distance, thereby driving the mounting block 2051 to move upward to match the winding height on the winding roller, ensuring that the conductor can be properly inspected.

However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
