Description

Technical Field

[0001] This utility model relates to the field of steel transportation technology, specifically a multi-fixed structure for steel transportation. Background Technology

[0002] During steel transportation, securing steel plates (especially rectangular plates) is a crucial step in ensuring transport safety. Existing securing structures often suffer from the following problems: First, they lack versatility, making it difficult to adapt to steel plates of different lengths and widths. For plates with varying dimensions, different securing components often need to be replaced, resulting in cumbersome operations. Second, they lack stability. Traditional securing methods often employ a single-direction or single-type locking structure, which is insufficient to effectively limit the multiple edges and corners of the plate. During transport, the plate is prone to displacement, shaking, or even falling, potentially damaging the steel plate and posing safety hazards. Third, they lack ease of loading and unloading. Some securing structures require repeated disassembly and adjustment of multiple components when placing and removing plates, affecting transportation efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a multi-fixed structure for steel transportation to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-fixed structure for steel transportation, including a placement frame, wherein a plurality of limiting screws are arranged in a rectangular array on the placement frame, and the lower ends of the limiting screws all move through the placement frame;

[0005] Both right-angled limit screws are threaded with hexagonal nuts, and the lower end of the hexagonal nut contacts and locks the upper edge of the steel.

[0006] The other two right-angled limit screws are each threaded with a tapered nut, and the inclined side of the tapered nut contacts and locks the upper edge of the steel.

[0007] Preferably, the lower end of the limiting screw is provided with a head, and a return spring wrapped around the limiting screw is connected between the head and the bottom of the placement frame.

[0008] Preferably, the placement rack is provided with support pillars at the four corners of its lower end.

[0009] Preferably, the upper end of the tapered nut is provided with an integrally formed hexagonal nut.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. Multiple fixings for strong stability: The rectangular array of limiting screws on the placement frame locks the two right-angled sides of the steel plate. One right-angled side is directly pressed against the edge of the plate with a hexagonal nut, while the other right-angled side is locked by contact with the bevel of a conical nut, forming a double limiting mechanism. The plate is fixed from two vertical directions, effectively preventing the plate from shifting and shaking during transportation, and significantly improving the fixing stability.

[0012] 2. Good versatility and adaptable to multiple sizes: The beveled design of the tapered nut allows it to adapt to steel plates of different lengths and widths during the tightening process.

[0013] 3. Convenient operation and improved efficiency: The return spring at the lower end of the limit screw can automatically reset after the plate is hoisted and placed, which facilitates quick adjustment of the screw position; the hexagonal nut structure with one-piece molding at the upper end of the conical nut, as well as the design of the hexagonal nut itself, make it easy to quickly rotate and lock or loosen with tools, simplifying loading and unloading operations and improving the efficiency of operations before and after transportation.

[0014] 4. Simple structure and high practicality: The overall structure consists of basic components such as a placement frame, a limiting screw, and a nut. The design is simple and easy to manufacture and maintain. The support column at the lower end of the placement frame provides ample space for the extension and retraction of the limiting screw, ensuring smooth operation of the structure and further enhancing its practicality.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3This utility model provides a technical solution: a multi-fixed structure for steel transportation, including a placement frame 1, on which a plurality of limiting screws 2 are arranged in a rectangular array, and the lower ends of the limiting screws 2 all move through the placement frame 1;

[0021] Both right-angled limiting screws 2 are threaded with hexagonal nuts 3, and the lower end of the hexagonal nuts 3 contacts and locks the upper edge of the steel.

[0022] The other two right-angled limit screws 2 are each threaded with a tapered nut 4, and the inclined side of the tapered nut 4 contacts and locks the upper edge of the steel.

[0023] Furthermore, the lower end of the limiting screw 2 is provided with a head 21, and a return spring 22 wrapped around the limiting screw 2 is connected between the head 21 and the bottom of the placement frame 1. When the steel plate is hoisted and placed on the placement frame 1, the limiting screw 2 is pressed down accordingly. After hoisting and unloading, the limiting screw 2 returns to its original position under the elastic force of the return spring 22.

[0024] Furthermore, support columns 11 are provided at the four corners of the lower end of the placement rack 1. The support columns 11 create a space at the lower end of the placement rack 1 that facilitates the extension and retraction of the limiting screw 2.

[0025] Furthermore, the upper end of the tapered nut 4 is provided with an integrally formed hexagonal nut 3. The hexagonal nut 3 structure at the upper end of the tapered nut 4 facilitates the rotation and downward movement of the tapered nut 4, thereby locking and fixing the steel plate.

[0026] Specifically, firstly, the steel plate is placed on the placement frame 1 using hoisting equipment. During placement, one right-angled side of the steel plate is aligned with one right-angled side of the limiting screw 2 set in the rectangular array. The limiting screw 2 on the right-angled side is screwed into the hexagonal nut 3 until it presses the upper edge of the steel plate, thus locking one right-angled side of the steel plate.

[0027] For the other right-angled side of the steel plate, screw a tapered nut 4 onto the adjacent limiting screw 2 on the other right-angled side until the inclined side of the tapered nut 4 contacts and locks with the upper edge of the steel plate. The tapered nut 4, as it moves downwards, accommodates different length and width dimensions of the steel plate.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
