Description

Technical Field

[0001] This utility model belongs to the field of loading plate technology and relates to an adjustment structure for a loading plate. Background Technology

[0002] Steel coils are generally transported on roads by large trucks. Due to the difficulty in securing steel coils, the fatal impact of inertial impact, the threat of centrifugal force during turns, and the increased risks due to overloading, they are known as "truck killers" because of their high risk.

[0003] When steel coils are transported on large trucks, they need to be secured. Existing steel coil securing methods, such as the load restraint assembly disclosed in Chinese patent literature [Patent No.: 200980100904.9; Application Publication No.: CN101848824B], include at least one row of openings, such as keyholes, spaced at intervals along at least a portion of the length of the pallet. The assembly also includes at least one wedge for positioning and / or restraining the load to move forward or backward on the pallet. The wedge has a locking member received in the keyhole so that the wedge can be supported and restrained at a selected location on the pallet. The assembly also includes at least one support for positioning and supporting the load on the pallet, such as long cargo.

[0004] This type of load constraint assembly features a locking member at the bottom of the wedge. During installation, the steel coil is placed on a tray, and the locking member is inserted into the keyhole and rotated 90° to engage the wedge with the tray. The wedge is then embedded in the spaces on both sides of the bottom of the steel coil, and its inclined surface holds the coil in place. However, in this type of load constraint assembly, the wedge and tray are separate. During installation, each wedge must be fixed to the tray individually. When the first three wedges are installed, the steel coil is not yet positioned, leading to rolling and reduced safety. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the prior art by proposing an adjustment structure for a loading plate, thereby solving the technical problem of how to improve safety.

[0006] The objective of this utility model can be achieved through the following technical solution: an adjustment structure for a loading plate, the loading plate including a frame-shaped bottom frame, characterized in that the adjustment structure includes two guide posts coaxially fixed in the bottom frame and an adjustment arm axially slidable on the guide posts, a placement space for placing steel coils and sleepers is provided between the two guide posts, the guide posts have a plurality of adjustment holes spaced apart along the axial direction of the guide posts, the adjustment arm has a through hole, and the adjustment arm is positioned with the guide posts by a pin passing through the through hole and the adjustment hole.

[0007] During operation, the steel coil is hoisted and placed in the designated space. Then, sleepers are placed in the spaces on both sides of the bottom of the coil. These sleepers limit the position of the coil, preventing movement during operator adjustments and improving safety. The operator moves the adjusting arm along the guide post until it rests against the outer side of the sleeper, positioning it optimally. A pin is then inserted into the through hole and adjusting hole to fix the adjusting arm to the guide post, ensuring the sleeper is firmly against the steel coil. This prevents the sleeper from loosening and the coil from moving, facilitating operation and positioning, and enhancing safety.

[0008] In the above-described adjustment structure for a loading plate, the guide post is cylindrical or tubular, and the adjustment arm includes a cylindrical adjustment portion sleeved on the guide post and a support portion fixed to the adjustment portion. The through hole is located in the adjustment portion, and one end of the support portion protrudes outside the adjustment portion, with a planar support surface at one end. This structure allows the adjustment arm to move smoothly along the guide post. The protruding support portion ensures the adjustment arm can rest against the sleeper, and the support surface increases the contact area, allowing the adjustment arm to better press down on the sleeper, preventing it from loosening and improving safety. Simultaneously, the cylindrical or tubular shape of the guide post and the cylindrical shape of the adjustment portion allow the adjustment arm to rotate around the guide post.

[0009] In the above-described adjustment structure of the loading plate, the central axis of the adjustment hole is arranged vertically. When the pin passes through the through hole and the adjustment hole to position the adjustment arm with the guide post, the adjustment arm is arranged vertically, and the support part is located above the bottom frame vertically. This structure facilitates pin insertion, and the vertical location of the support part above the bottom frame allows the adjustment arm to better press down on the sleeper.

[0010] In the aforementioned adjustment structure for a loading plate, the guide post further includes at least one positioning hole. The central axis of the positioning hole is horizontally oriented. When the pin passes through the through hole and the positioning hole to position the adjusting arm against the guide post, the adjusting arm is horizontally oriented and embedded in the bottom frame. This structure prevents the adjusting arm from protruding from the bottom frame when retracted, prevents the steel coil from getting stuck during placement, and ensures that the loading plates do not jam when stacked together, making storage of the loading plates convenient.

[0011] In the aforementioned adjustment structure for a loading platform, the bottom frame includes a pair of forklift tubes. The forklift tubes have a rectangular cross-section and are located between two guide posts, perpendicular to the guide posts. The forklift tubes allow the fork arms of a forklift to extend into them, enabling the loading platform to be moved by the forklift.

[0012] Compared with the prior art, the adjustment structure of the loading plate provided by this utility model has the following advantages:

[0013] 1. When positioning the steel coil, this loading plate first uses sleepers to prevent the steel coil from moving while the operator is fine-tuning the position of the sleepers, thus improving safety; at the same time, the adjusting arm ensures that the sleepers are tightly attached to the steel coil, preventing the sleepers from loosening and the steel coil from moving, thus improving safety.

[0014] 2. The adjusting arm of this adjusting structure can rotate around the guide column, so that when the loading plate is stored, the adjusting arm can be placed horizontally so that the adjusting arm is not exposed, making the loading plate easy to store. Attached Figure Description
