[0002] The transformer core is assembled on site by stacking the frames, that is, the core frames are stacked together. After the core is arranged, the lower end of the middle column core frame is tightened with a ring-shaped soft pull belt. The soft pull belt is installed beside the lower iron yoke and fixed on the clamp limb plate. In order to facilitate the winding of the soft pull belt, a winding tool is generally used;

[0003] The winding tooling in the prior art sets the winding length of the soft pull tape to a fixed value. However, due to the flexibility of the soft pull tape itself, it is easy to loosen or shift during the winding process, which will affect the fastening effect of the core frame, thereby reducing the performance and stability of the transformer. In addition, when loosening or shifting problems occur, the winding tooling in the prior art cannot issue an early warning in time to remind the staff to take corresponding measures.

[0004] In order to solve the above problems, the present application proposes a soft pull belt winding tool for on-site assembly products. Utility Model Content

[0005] Based on the technical problems existing in the background technology, the utility model proposes a soft pull belt winding tool for on-site assembly products.

[0008] When the soft pull belt is wound between the two screw rods, the elastic top piece is pushed to press against the pressure warning piece.

[0009] Preferably, the elastic top piece includes a top rod, a U-shaped block, a spring and a shaft rod, the movable block is mounted with a fixed block, the fixed block is provided with a through hole, the top rod slides transversely through the through hole, the U-shaped block is mounted on one end of the top rod close to the screw rod, the spring is sleeved on the top rod and is located between the U-shaped block and the fixed block, and the two ends of the spring are respectively connected to the U-shaped block and the fixed block, a U-shaped opening is formed on the side of the U-shaped block close to the screw rod, the shaft rod is rotatably mounted in the U-shaped opening, and the outer periphery of the shaft rod abuts against the screw rod.

[0010] Preferably, the pressure warning component includes a sleeve, a pressure sensor and a buzzer. The sleeve is installed on a side of the fixed block away from the screw. An insertion cavity is opened in the sleeve. The end of the push rod away from the U-shaped block is inserted into the insertion cavity. A pressure sensor is installed at the end of the insertion cavity. The distance between the pressure sensor and the push rod is adapted to the number of turns of the soft pull belt.

[0014] Through the elastic top piece, the distance between the two moving blocks on the channel steel can be adjusted as needed, and then the soft pull belt can be wound on the two screws. When the soft pull belt is wound on the screw, the elastic top piece can be used to abut the soft pull belt, and a certain pressure can be applied to the soft pull belt to effectively prevent it from loosening and shifting. This structure applies pressure to the soft pull belt through the adjustable moving block distance and the elastic top piece, effectively preventing it from loosening and shifting, thereby improving the winding accuracy;

[0015] By setting up the pressure warning part, when the soft pull belt is being wound, an outward thrust can be applied to the elastic top part. When the soft pull belt is wound to a corresponding number of turns, the elastic top part is pressed against the pressure warning part under the action of the thrust. The soft pull belt can be monitored in real time through the pressure warning part. When the soft pull belt becomes loose, an early warning can be issued to serve as a reminder. The structure realizes real-time monitoring of the winding process of the soft pull belt through the cooperation of the elastic top part and the pressure warning part. When the soft pull belt becomes loose, an early warning can be issued in time to remind the staff to take measures to avoid potential risks. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0020] like Figure 1 and Figure 2 As shown, the utility model provides a soft pull belt winding tool for on-site assembly products, including a channel steel 1;

[0021] In this embodiment, two moving blocks 2 are installed on the channel steel 1, and the distance between the two moving blocks 2 is adjustable. A slide groove is provided on the channel steel 1, and the two moving blocks 2 are slidably connected to the slide groove. Both sides of the channel steel 1 are threaded with screw rods 7 extending into the slide groove, and the opposite ends of the two screw rods 7 are rotatably connected to the two moving blocks 2 respectively.

[0022] In this embodiment, the two moving blocks 2 are both provided with screw rods 3, and the moving blocks 2 are provided with elastic top pieces 4 that abut against the screw rods 3. The elastic top pieces 4 include a top rod 41, a U-shaped block 42, a spring 43, and a shaft rod 44. The moving blocks 2 are provided with a fixed block 6, and a through hole is provided in the fixed block 6. The top rod 41 slides transversely through the through hole. The U-shaped block 42 is installed at one end of the top rod 41 close to the screw rod 3. The spring 43 is sleeved on the top rod 41 and is located between the U-shaped block 42 and the fixed block 6, and the two ends of the spring 43 are respectively connected to the U-shaped block 42 and the fixed block 6. A U-shaped opening is formed on one side of the U-shaped block 42 close to the screw rod 3. The shaft rod 44 is rotatably installed in the U-shaped opening, and the outer periphery of the shaft rod 44 abuts against the screw rod 3.

[0023] It should be noted that:

[0024] In order to prevent the soft pull belt from loosening or shifting during winding, first, fix the tooling on a plane with a calliper to ensure that the tooling does not move, and then rotate the screw rod 7 as needed to push the moving block 2 to move in the slide groove opened on the channel steel 1, so as to adjust the distance between the two moving blocks 2, and then wind the soft pull belt on the two screw rods 3. When the soft pull belt is wound on the screw 3, the shaft rod 44 on the U-shaped block 42 can be used to support the soft pull belt. Under the action of the spring 43, a certain pressure can be applied to the soft pull belt. During the winding process, the soft pull belt can drive the shaft rod 44 to rotate on the U-shaped block 42, thereby improving the winding efficiency of the soft pull belt. The structure applies pressure to the soft pull belt through the adjustable distance of the moving block 2 and the elastic top piece 4, effectively preventing loosening and shifting, thereby improving the winding accuracy.

[0025] In a further embodiment, a pressure warning member 5 is provided at the end of the elastic top member 4; when the soft pull belt is wound between the two screws 3, the elastic top member 4 is pushed to press against the pressure warning member 5. The pressure warning member 5 includes a sleeve 51, a pressure sensor 52 and a buzzer 53. The sleeve 51 is installed on the side of the fixed block 6 away from the screw 3. An insertion cavity is provided in the sleeve 51. The end of the top rod 41 away from the U-shaped block 42 is inserted into the insertion cavity. The pressure sensor 52 is installed at the end of the insertion cavity. The spacing between the pressure sensor 52 and the top rod 41 is adapted to the number of turns of the soft pull belt. The sleeve 51 is installed with a buzzer 53, and the buzzer 53 is electrically connected to the pressure sensor 52.

[0026] It should be noted that:

[0027] In order to be able to give a timely warning after the soft pull belt is loose, when the soft pull belt is being wound, an outward thrust can be applied to the shaft rod 44, so that the push rod 41 slides in the insertion cavity opened in the sleeve 51, and when the soft pull belt is wound to a corresponding number of turns, the push rod 41 is pressed against the pressure sensor 52 under the action of the thrust, and the soft pull belt can be monitored in real time through the pressure sensor 52. When the soft pull belt is loose, the push rod 41 is separated from the pressure sensor 52, and when the pressure value of the pressure sensor 52 changes, the changed value is transmitted to the buzzer 53, and an alarm can be issued through the buzzer 53 to serve as a reminder. The structure realizes real-time monitoring of the winding process of the soft pull belt through the cooperation of the elastic top member 4 and the pressure warning member 5. When the soft pull belt is loose, a warning can be issued in time to remind the staff to take measures to avoid potential risks.

[0028] In a specific embodiment, a thread groove is provided in the moving block 2, and the bottom end of the screw rod 3 is threadedly connected in the thread groove. The screw rod 3 is threadedly connected in the thread groove, so that it is easy to disassemble and assemble.
