Detailed Implementation

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] like Figures 1 to 4 As shown, this embodiment provides a steel strand taking frame, including two side frames 1 distributed opposite to each other. A screw 2 is inserted between the four corners of the two side frames 1. The end of the screw 2 is threaded with a nut 3. A through groove 4 for adjusting the height of the screw 2 is provided on the side frame 1. A steel strand taking port 5 is provided in the middle of the side frame 1.

[0022] By adjusting the position of the nut 3 on the screw 2, the distance between the two side frames 1 can be adjusted to accommodate steel strand coils of different widths. Simultaneously, the height of the screw 2 can be adjusted by raising and lowering it within the through slot 4 to accommodate steel strand coils of different diameters.

[0023] During use, first connect the two lower screws 2 with nuts 3 to the two side frames 1, then place the steel strand coil in the machine. Next, connect the tops of the two upper screws 2 with nuts 3. After placing the steel strand coil into the two side frames 1 and securing it, unpack and untension it. Pull it out from the inner diameter end access port 5 of the steel strand and cut it to the desired length. After use, secure the end of the steel strand with tie wire.

[0024] In a relatively specific embodiment, two parallel columns 1.1, two horizontal beams 1.2 arranged between the two columns 1.1 and arranged vertically in parallel, and two horizontal beams 1.3 arranged between the two horizontal beams 1.2 and arranged laterally in parallel, are connected by an opening 5 enclosed by the horizontal beams 1.2 and the vertical beams 1.3. A through groove 4 is provided at both ends of the columns 1.1. In this embodiment, the columns 1.1, horizontal beams 1.2, and vertical beams 1.3 are all made of channel steel.

[0025] The end of the screw rod 2 is provided with a pad plate 6 which is padded between the column 1.1 and the nut 3. The pad plate 6 is used to separate the nut 3 from the column 1.1, preventing the nut 3 from entering the slot cavity of the column 1.1. At the same time, it increases the force area when the nut 3 is pressed, making the force more uniform.

[0026] The side surface of the column 1.1 and the pad plate 6 in contact with each other is provided with an inclined surface which is inclined inwardly from the top end. In this way, after the height adjustment of the screw rod 2 and the tightening of the nut 3, the screw rod 2 will not be displaced downward under the action of the gravity of the steel strand coil, thereby maintaining the stability of the height of the steel strand coil and stably supporting the steel strand coil at the preset height.

[0027] The screw rod 2 is divided into a first threaded section 2.1 and a plurality of sequentially distributed second threaded sections 2.2. One end of the second threaded section 2.2 is provided with a plug rod 7, and the other end of the second threaded section 2.2 and one end of the first threaded section 2.1 are provided with plug slots 8 for insertion and expansion movement. The threads between the first threaded section 2.1 and the second threaded section connected thereto and between the two second threaded sections 2.2 connected to each other are in a connected state.

[0028] The part between the two side frames 1 is a second threaded section 2.2 for supporting the steel strand coil. In use, the support of the second threaded section 2.2 on the steel strand coil is maintained by the state that the end of the plug rod 7 is inserted into the plug slot 8, and at the same time, the rotation of the second threaded section 2.2 is realized by the rotation of the plug rod 7 in the plug slot 8. At this time, in the process of using the steel strand, when the bending tension of the steel strand located at the center position of the steel strand coil is large, and the steel strand located outside the access port 5 is not easy to rotate to remove the bending tension, the bending tension of the steel strand can be directly removed by directly rotating the second threaded section 2.2, so that the worker can directly push the steel strand coil to rotate, thereby further facilitating the threading operation of the steel strand.

[0029] Further, the end of the first threaded section 2.1 towards the second threaded section 2.2 and the two ends of the second threaded section 2.2 are provided with matched positioning rods 9 and positioning slots 10. When the positioning rods 9 and the positioning slots 10 on the first threaded section 2.1 and the second threaded section 2.2 are in a plug-in state, the threads of the first threaded section 2.1 and the second threaded section 2.2 are in a connected state, and when the positioning rods 9 and the positioning slots 10 on the two adjacent second threaded sections 2.2 are in a plug-in state, the threads on the two second threaded sections 2.2 are in a connected state. The length of the positioning rod 9 is less than the extension distance of the plug rod 7 in the plug slot 8.

[0030] In the embodiment, the threads between the first threaded section 2.1 and the second threaded section 2.2 and between two adjacent second threaded sections 2.2 can be kept in engagement by inserting the positioning rod 9 into the positioning slot 10. During use, the second threaded section 2.2 is separated by rotating the nut 3, and the nut 3 is abutted on the pad 6, the two nuts 3 on the same threaded rod 2 are separated, at this time, the insertion rod 7 is displaced outward in the insertion slot 8, and the positioning rod 9 and the positioning slot 10 are separated, and the two second threaded sections 2.2 in the separated state can be rotated relative to each other to adapt to the rotation of the steel strand coil and remove the bending tension of the steel strand.

[0031] The end inner wall surface of the insertion slot 8 is rotatably connected with the spring 11, and one end of the spring 11 is connected with the insertion rod 7. Specifically, the end inner wall surface of the insertion slot 8 is rotatably connected with the spring 11 seat, and one end of the spring 11 is connected with the spring 11 seat. The elastic force of the spring 11 can keep the threads of the two adjacent second threaded sections 2.2 and the threads between the first threaded section 2.1 and the second threaded section 2.2 in engagement when the positioning rod 9 is inserted into the positioning slot 10, and the rotation of the nut 3 on the threaded rod 2 is more convenient.

[0032] The outer side of the pad 6 is rotatably connected with the pad ring 12, and the nut 3 is in contact with the pad ring 12. The pad ring 12 can reduce the resistance of the nut 3 during the process of contacting the pad ring 12 and continuing to rotate to separate the second threaded section 2.2, and the operation is more convenient.

[0033] The technical scope of the utility model is not limited to the above description, and those skilled in the art can make various modifications and changes to the above embodiments without departing from the technical concept of the utility model, and these modifications and changes should be within the scope of the utility model.
