[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0020] The following description is intended to disclose the present invention and enable those skilled in the art to implement the present invention. The preferred embodiments described below are provided for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0021] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms cannot be understood as limiting the present invention.

[0022] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0023] like Figure 1-3 As shown, a preferred embodiment of the present invention provides a steel strand quick extraction device, comprising:

[0024] A pair of brackets 1 are vertically spaced apart; a steel strand outlet 2 is provided on each bracket 1;

[0025] A plurality of connecting rods 3 are arranged transversely between the two brackets 1, and the length of the connecting rods 3 is adjustable;

[0026] The steel strand coil is arranged between the two brackets 1 and sleeved outside the connecting rod 2;

[0027] A guide device 4 is transversely mounted on the outer side of one of the brackets 1 and extends transversely through the guide device 4. The interior of the guide device 4 is connected to the steel strand outlet. The free end of the steel strand coil passes through the steel strand outlet and through the guide device, and finally connects to the power traction mechanism. The guide device 4 is tapered, with one end of the guide device 4 connected to the bracket 1 being larger and the other end being smaller.

[0028] In the above technical solution, a power traction mechanism is used to pull the steel strand from the steel strand outlet on the bracket 1 and pull it out through the guide device, so that the steel strand can be pulled out quickly and conveniently. The utility model is simple to manufacture, easy to operate, accurately positioned, low in manufacturing cost, and reusable, which greatly improves the efficiency of straightening and extracting the steel strand, reduces the tool damage rate, and reduces construction cost and time. Moreover, considering that the width dimensions of different steel strand rolls are different, the length of the connecting rod 3 is set to be adjustable in this application, which can be adjusted according to the width of the steel strand roll, and is more practical. Moreover, since the utility model adopts the method of extracting the steel strand from the inside, the steel strand quick extraction device can also be used in narrow spaces.

[0029] According to a preferred embodiment of the present invention, the connecting rod 2 includes a main sleeve 2-1 and side rods 2-2 threaded into the ends of the main sleeve 2-1. The outer walls of the side rods and the inner wall of the main sleeve are respectively provided with mutually compatible external and internal threads. The length of the connecting rod is adjusted by adjusting the length of the side rods threaded into the main sleeve. The bracket 1 is provided with a mounting hole, the size of which is larger than the size of the ends of the connecting rod, and the ends of the connecting rod are placed in the mounting hole.

[0030] In the above technical solution, when the length of the connecting rod 2 needs to be adjusted, the side rod can be screwed in or out of the main sleeve.

[0031] According to a preferred embodiment of the present invention, the guide device 4 includes a guide cylinder 4-1 and a guide ring 4-2. The guide cylinder 4-1 is a tapered frame structure, and at least one guide ring 4-2 is disposed inside the guide cylinder along its length. The free end of the steel strand coil passes through the steel strand outlet and sequentially through multiple guide rings 4-2 before finally connecting to the power traction mechanism. Using multiple guide rings 4-2 to guide the steel strand improves traction performance.

[0032] According to a preferred embodiment of the present invention, the bracket 1 is a triangular bracket, and the triangle has good stability.

[0033] According to a preferred embodiment of the present invention, at least two limiting rods 5 are horizontally arranged between a pair of brackets 1. The multiple limiting rods are arranged at intervals and close to the surface of the steel strand roll. The limiting rods 5 are used to limit the surface of the steel strand roll, which is equivalent to using the connecting rod 3 and the limiting rod 5 to position the steel strand roll as a whole at the same time, and the positioning effect is good.

[0034] According to a preferred embodiment of the present invention, a fixing rod 6 is provided between the bottoms of a pair of brackets, and the length of the fixing rod is adjustable, which is also to adapt to when the length of the connecting rod 2 needs to be adjusted.

[0035] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with this field, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
