Description
Technical Field
[0001] This utility model relates to the field of wire threading equipment technology, specifically to a wire threading device for power engineering. Background Technology
[0002] In the construction and maintenance of power engineering projects, wire pulling is an essential but time-consuming and labor-intensive task. Existing wire pullers for power engineering have many problems in practical applications. For example, the winding method of traditional wire pullers is relatively simple, and the wire is prone to loosening when wound on the reel, leading to low pulling efficiency and the possibility of the wire and reel detaching during the pulling process. Most wire pullers have inflexible connection structures with the wires, resulting in poor connection stability and a tendency to detach during pulling. Furthermore, existing wire pullers generally require manual operation. After the connecting wire is manually passed through the conduit and connected to the wire, one worker rotates the reel or pulls the wire at one end, while another worker pushes it at the other end to complete the pulling operation. Therefore, there is a need to design a stable device that can replace manual wire pulling. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a wire puller for power engineering, which drives the wire reel to rotate via a stepper motor to achieve automated wire take-up and unwinding, reducing manual labor intensity. The design of the connecting block and connector at the outer end of the connecting wire effectively enhances the adaptability of the wire puller to various types of wires, strengthens the fixation of the wire and the connecting wire, and prevents the connection from becoming loose.
[0004] A cable puller for power engineering includes a base, a support plate fixedly mounted on the upper side of the base, a cable reel rotatably connected to one end of the support plate, an output shaft of a motor fixedly connected to one end of the central shaft of the cable reel, and a stepper motor fixedly connected to one side of the support plate.
[0005] A set of evenly arranged winding rods is fixedly installed in the middle of the inside of the winding spool. The winding rods are square rods with through holes to facilitate the connection wire to pass through and wind around all the winding rods.
[0006] As a further limitation of this technical solution, a cylindrical connecting block is fixedly provided at the outer end of the connecting line. The diameter of the connecting block is smaller than the diameter of the connecting line. A connector is fixedly provided at the other end of the connecting block. One side of the connector is cylindrical. The cross-sectional diameter of the connector is the same as the cross-sectional diameter of the connecting line. A sphere is rotatably connected inside the notch of the connector. The arc surface of the sphere extends out of the notch of the connector.
[0007] As a further limitation of this technical solution, the connecting block is provided with a connecting hole to facilitate the binding wire to be passed through and bound to the connecting wire.
[0008] As a further limitation of this technical solution, a fifth auxiliary shaft, a fourth auxiliary shaft, a second auxiliary shaft, and a third auxiliary shaft are rotatably provided on one side of the support plate. The fifth auxiliary shaft, the fourth auxiliary shaft, the second auxiliary shaft, and the third auxiliary shaft are arranged sequentially along a first direction. The axes of the fifth auxiliary shaft, the fourth auxiliary shaft, the second auxiliary shaft, and the third auxiliary shaft are alternately arranged one above the other. The first direction is the direction extending from one end of the support plate that is rotatably connected to the winding reel to the other end of the support plate.
[0009] As a further limitation of this technical solution, a linear track is also provided. The fixed end of the linear track is fixed to the upper side of the support plate, and the movable end of the linear track is fixed to the lower side of the sliding seat. A spring connecting post one is fixedly provided on the upper side of the sliding seat. The spring connecting post one can be hooked by a hook at one end of the spring, and the hook at the other end of the spring can hook a spring connecting post two. The spring connecting post two is fixed to the upper side of the other end of the support plate.
[0010] As a further limitation of this technical solution, one side of the sliding seat is rotatably connected to a first auxiliary shaft, the first auxiliary shaft is disposed above the second auxiliary shaft, and under the action of the spring, the axis of the first auxiliary shaft is positioned between the axes of the second auxiliary shaft and the third auxiliary shaft.
[0011] Compared with the prior art, the advantages and positive effects of this utility model are:
[0012] Driven by a stepper motor, the winding reel rotates. Combined with the square winding rods and threading holes evenly arranged around the circumference of the winding reel, the connection wire can be firmly secured. Users can flexibly choose to pass the wire through the threading holes sequentially or intermittently, so that the connection wire is firmly fixed to the winding reel. Removal is also very convenient, which greatly improves the stability of the connection wire during the threading operation. At the same time, it realizes automated wire winding and unwinding, reducing the intensity of manual labor.
[0013] The design of the connecting block and connector at the outer end of the connecting cable effectively enhances the compatibility of the cable puller with various types of wires. The smaller diameter of the connecting block facilitates connection with the wire, and the connection hole makes it easy to bind the wire through, strengthening the fixation between the wire and the connecting cable and preventing the connection from becoming loose. The rotating ball inside the connector allows the connector to move quickly along the conduit when pulling the wire, reducing frictional resistance and improving the smoothness of pulling and the stability of the connection.
[0014] Multiple auxiliary shafts arranged alternately on the support plate provide good guidance for the connecting line. The rotating auxiliary shafts reduce friction during line movement and reduce wear. The tortuous path formed by the special arrangement enhances the constraint on the connecting line. The linear track, sliding seat, spring connecting column and spring work together to flexibly adjust the initial tension of the connecting line. The first auxiliary shaft can automatically adjust its position according to the tension change under the action of the spring, and maintain tension balance together with other auxiliary shafts.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0022] A cable puller for power engineering includes a base 13, a support plate 11 fixedly disposed on the upper side of the base 13, a cable reel 1 rotatably connected to one end of the support plate 11, an output shaft of a motor 12 fixedly connected to one end of the central shaft of the cable reel 1, and the motor 12 fixedly connected to one side of the support plate 11. The motor 12 is a stepper motor 12.
[0023] A set of evenly arranged winding rods 15 are fixedly installed in the middle of the inside of the winding reel 1. The winding rods 15 are square rods and have wire holes 16, so that the connecting wire 6 can pass through and be wound along all the winding rods 15.
[0024] In this embodiment, a motor 12 (stepper motor 12) drives the central shaft of the winding reel 1 to rotate, thereby realizing the rotation function of the winding reel 1. Square winding rods 15 are evenly arranged in a circle inside the winding reel 1, and threading holes 16 are opened. The structure of the winding rods 15 and the threading holes 16 guides the connecting wire 6 to wind. The connecting wire 6 can pass through the threading holes 16 sequentially or intermittently before winding around all the winding rods 15. This makes it easy to firmly fix one end of the connecting wire 6 to the winding reel 1 and easy to remove the connecting wire 6. This makes it easy to keep the connecting wire 6 stable when using the threader. The motor 12 drives the winding reel 1 to rotate to realize the winding and unwinding functions, replacing manual labor and making it convenient to use.
[0025] A cylindrical connecting block 17 is fixedly provided at the outer end of the connecting line 6. The diameter of the connecting block 17 is smaller than the diameter of the connecting line 6. A connector 18 is fixedly provided at the other end of the connecting block 17. One side of the connector 18 is cylindrical. The cross-sectional diameter of one side of the connector 18 is the same as the cross-sectional diameter of the connecting line 6. A sphere 19 is rotatably connected inside the notch of the connector 18. The arc surface of the sphere 19 extends out of the notch of the connector 18.
[0026] In this embodiment, the design of the connecting block 17 and the connector 18 enhances the adaptability of the wire puller to different types of wires. The smaller diameter of the connecting block 17 facilitates the connection between the wire and the connecting block 17, and makes it convenient to bind the wire and the connecting wire 6 together with the binding wire (the binding wire is a common existing product in existing wire pullers that binds the connecting wire 6 and the wire together, which is not shown in the figure and will not be described in detail). This facilitates a stable connection between the binding wire and the connecting wire 6. The rotating ball 19 allows the connector 18 to move quickly along the conduit when the wire is being pulled after being connected to it.
[0027] The connecting block 17 has a connecting hole 171, which facilitates the passing of the binding wire and the binding of the wire to the connecting wire 6. The connecting hole 171 facilitates the passing of the binding wire, enhances the stable connection between the binding wire and the connecting block 17, and prevents the binding wire from accidentally falling off during the wire threading process, which could lead to the separation of the connecting wire 6 and the wire.
[0028] A fifth auxiliary shaft 101, a fourth auxiliary shaft 10, a second auxiliary shaft 7, and a third auxiliary shaft 8 are rotatably provided on one side of the support plate 11. The fifth auxiliary shaft 101, the fourth auxiliary shaft 10, the second auxiliary shaft 7, and the third auxiliary shaft 8 are arranged sequentially along a first direction. The axes of the fifth auxiliary shaft 101, the fourth auxiliary shaft 10, the second auxiliary shaft 7, and the third auxiliary shaft 8 are alternately arranged one above the other. The first direction is the direction extending from one end of the support plate 11 that is rotatably connected to the winding reel 1 to the other end of the support plate 11.
[0029] In this embodiment, multiple auxiliary shafts (fifth auxiliary shaft 101, fourth auxiliary shaft 10, second auxiliary shaft 7, and third auxiliary shaft 8) are rotatably arranged on one side of the support plate 11. Each auxiliary shaft is arranged sequentially along a specific direction (extending from one end of the support plate 11 to the other end of the rotatable winding reel 1), and the shaft centers are alternately arranged one above the other. The rotation of the auxiliary shafts and the special arrangement method guide the connecting line 6. The rotation of the auxiliary shafts can reduce the friction of the connecting line 6 during the movement process and reduce the wear of the line. The arrangement method of the shaft centers being alternately arranged one above the other makes the connecting line 6 form a tortuous path when passing through the auxiliary shafts, which increases the constraint and guiding effect on the connecting line 6.
[0030] A linear track 14 is also provided. The fixed end of the linear track 14 is fixed to the upper side of the support plate 11, and the movable end of the linear track 14 is fixed to the lower side of the sliding seat 2. A spring connecting post 1 3 is fixedly provided on the upper side of the sliding seat 2. The spring connecting post 1 3 can be hooked by a hook at one end of a spring 4. The hook at the other end of the spring 4 can hook a spring connecting post 2 31. The spring connecting post 2 31 is fixed to the upper side of the other end of the support plate 11.
[0031] The sliding seat 2 is rotatably connected to a first auxiliary shaft 5 on one side. The first auxiliary shaft 5 is located above the second auxiliary shaft 7. Under the action of the spring 4, the axis of the first auxiliary shaft 5 is located between the axes of the second auxiliary shaft 7 and the third auxiliary shaft 8.
[0032] In this embodiment, after the spring 4 hooks onto the spring connecting post 1 3 and the spring connecting post 2 31, the elastic deformation of the spring 4 generates tension, which in turn generates pressure on the top of the connecting line 6 through the first auxiliary shaft 5. The addition and special positioning of the first auxiliary shaft 5, in conjunction with other auxiliary shafts, further refines the guiding path of the connecting line 6 and enhances the control over the direction of the connecting line 6. Under the action of the spring 4, the first auxiliary shaft 5 can flexibly adjust its position according to the tension changes of the connecting line 6, and together with other auxiliary shafts, maintain the tension balance of the connecting line 6, ensuring that the threading process is stable and efficient.
[0033] The connecting wire 6 can be the wire from an existing threader.
[0034] The method of using this utility model is as follows: Place the base 13 in a suitable position, connect the spring connecting post 1 3 and the spring connecting post 2 31 through the spring 4, pass one end of the connecting wire 6 through the thread hole 16 of the winding rod 15, and then wind it around all the winding rods 15 connected to the winding reel 1. After winding, pass the connecting wire 6 alternately through each auxiliary shaft (e.g., ...). Figure 1 (As shown in the winding state), insert the outer end of the connecting wire 6 with the ball 19 into the tube to be threaded. Start the stepper motor 12, which drives the winding reel 1 to rotate, controlling the winding reel 1 to unwind the wire. The connecting wire 6 moves along the tube until it passes through the tube, then stop the motor 12. According to the specifications of the wire to be threaded and the threading requirements, pass the binding wire through the connecting hole 171 on the connecting block 17 to securely bind the wire to the connecting wire 6. Then, control the output shaft of the motor 12 to rotate in the opposite direction, causing the winding reel 1 to wind up the wire. During the winding process, the wire follows the connecting wire 6 through the tube, realizing the threading operation. During the threading process, the connecting wire 6 passes around each auxiliary shaft in sequence, and each auxiliary shaft guides and constrains it. The first auxiliary shaft 5 is automatically adjusted under the action of the spring 4 to maintain the tension balance of the connecting wire 6. When the connector 18 pulls the wire to the target position, stop the motor 12 to rotate, and separate the wire from the connecting wire 6.
[0035] The above-disclosed embodiments are merely specific examples of this utility model. However, this utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
