[0001] This utility model relates to the field of transportation. Background Technology

[0002] Tensioning and positioning technology is widely used in machinery manufacturing, assembly, and transportation. It primarily uses tensioning devices to fix components, adjust tension, and achieve precise positioning. In railway product transportation, the C70E type general-purpose open wagon is typically used. Two boxes of products are placed side-by-side in one wagon, connected and fixed together, and then secured to the wagon. While securing the products to the wagon is relatively easy, connecting and securing the two boxes together presents significant challenges. Utility Model Content

[0019] like Figure 1-7 As shown, a product tensioning and positioning device for railway transportation includes a hook assembly 1, a pull ring 2, and a sleeve assembly 3. There are two pull rings 2 and two hook assemblies 1 (the two pull rings are symmetrical and the two hooks are symmetrical). The two ends of the sleeve assembly 3 are threadedly connected to a pull ring 2.

[0020] During use, hook 1 is attached to the connection point of the fiber optic cable between two products. The connection point is the hookable position formed by the binding straps during product packaging. For example, when the products are bound horizontally or vertically, a horizontal or vertical binding strap in the middle can serve as the connection point.

[0021] Each hook assembly includes a hook body 11, a stop plate 12, a hook pin 13, and a spring 14. The hook body 11 consists of a hook head and a hook shank. The end of the hook shank has a cuboid braking groove 16, and the hook shank has pin holes 17 on both sides corresponding to the braking groove 16. The inner side of the braking groove 16 has a spring hole 18. The stop plate 12 is a cuboid with one end rounded and has a curved groove 15. The hook pin 13 passes through the pin hole 17 and the braking groove 16. One end of the spring 14 is in the spring hole 18, and the other end is pressed against the stop plate 12. Each pull ring has a hook through-hole groove 25.

[0022] The hook body 11 is attached to the connection point of the fiber pull parts of the two products.

[0023] This unique hook structure allows the stop plate 12 to be either perpendicular to or parallel to the hook shank by moving it. When the stop plate 12 is moved parallel to the hook shank, the hook shank can be inserted into the hook through hole groove 25. After the hook shank is inserted into the hook through hole groove 25, moving the stop plate 12 makes it perpendicular to the hook shank, at which point the hook assembly and the pull ring are locked together.

[0024] The sleeve assembly 3 includes a sleeve body 31 and a sleeve pin. The sleeve body 31 has a sleeve pin hole 33 in the center and internal threads 32 at both ends. Each pull ring includes a cuboid pull ring body 21 and a pull ring handle 22 with external threads connected to the end of the pull ring body 21. The external threads of the pull ring handle 22 correspond to the internal threads 32 of the sleeve body 31, and the internal threads at both ends of the sleeve body 31 have opposite helical directions.

[0025] By rotating the sleeve pin, the sleeve body 31 is driven to rotate, thereby engaging the external thread of the pull ring handle 22 with the internal threads at both ends of the sleeve body 31, thus tightening the two pull rings.

[0026] The pull ring body 21 has handle fixing grooves 23 on both sides.

[0027] The tensioning and positioning device also includes a handle fixing pin, and the handle fixing groove 23 has a handle fixing hole 24 on the outside.

[0028] The handle fixing pin is a pin with a flat cap at one end and a locking hole at the other end.

[0029] The folding handle 4 has a handle pin hole. The sleeve pin passes through the sleeve pin hole 33 and the handle pin hole.

[0030] Rotating the sleeve pin by folding handle 4 can save effort and provide a large torque. When the sleeve body 31 and the two pull rings tighten the pipe to a suitable degree, the folding handle 4 is folded and placed in the handle fixing groove 23 to prevent loosening of the engagement. At the same time, the folding handle 4 can be locked by the handle fixing pin to prevent the folding handle 4 from coming out of the handle fixing groove 23.

[0031] The working principle of this utility model is as follows: First, the two boxes of products are hoisted into the railway vehicle and placed in place. Then, the two hook bodies 11 are hung on the connection position (fiber optic cable). The hook handle is passed through the hook through hole groove 25. The pull ring and hook are locked by moving the stop plate. Then, the pull ring and sleeve are suspended. After suspension, the folding handle is turned. After it is in place, the handle is folded and placed in the handle fixing groove 23 to ensure that the two boxes of products are fixed and locked in both the horizontal and vertical directions. This tensioning and positioning device can meet the requirements of fixing the products horizontally forward, backward, left and back, and vertically. It is suitable for two boxes of products transported by railway with a fixed connection position and limited connection space. The fixed position can only be the fiber optic cable. The space between the two boxes of products is only 200mm.
