Description

Multi-purpose support bar for dock loading and unloading

technical field

The utility model relates to a loading and unloading device, in particular to a multipurpose support bar for dock loading and unloading.

Background technique

The type of steel pipe cargo is a common type of cargo loaded and unloaded in ports; chemical fiber rope buckles and support rods are often used in conjunction with steel pipe cargo loading operations. Because this type of cargo has high requirements on the quality of work, it is usually not possible to use steel wire ropes but to use softer chemical fiber rope buckles for operations.

During operation, tie the steel pipes with chemical fiber rope buckles and place them on the flatbed truck. The weight of each bundle should not exceed the load of the rope buckles. The chemical fiber rope buckle is hung on the hook for lifting operation. At present, the following problems often occur when using ordinary support bars: the load of chemical fiber rope buckles used at the wharf is generally 10 tons for a pair of rope cranes. If the load increases, the diameter of the rope must be thicker, so it is inconvenient for loading and unloading personnel to operate Conducive to the buckle in the cabin. In the case of a 25-ton gantry crane at the wharf, in order to make full use of the machine power, it is necessary to lift two hooks each time. Since the chemical fiber rope buckles of the two hooks are connected to the same lifting point on the support bar, when the diameter of the steel pipe is large Or when the goods on land are stacked improperly, the goods with two hooks are likely to be stacked and squeezed when lifting, which will cause damage to the goods and cause uneven force on the rope buckle, which will cause hidden dangers to safe production.

Therefore, it is very necessary for those skilled in the art to further improve the current application status and provide a multi-purpose support bar for wharf loading and unloading with simple structure, wide application, and the ability to set lifting points horizontally in a short distance to meet the needs of loading and unloading construction operations.

Utility model content

The purpose of this utility model is to overcome the above disadvantages, effectively solve the problems of cargo damage and safety in steel pipe operation, and provide a multi-purpose support bar for wharf loading and unloading with simple and reasonable structure and convenient loading and unloading transportation, so as to meet the needs of steel pipe operation in general cargo wharf.

In order to achieve the above-mentioned purpose, the technical scheme adopted by the utility model is as follows: a multi-purpose support bar for loading and unloading at the wharf, which is characterized in that the support bar includes a main board, a reinforcing rib, a lug plate and a forklift hole; A strip-shaped steel plate is used as the main board part of the support bar. There are two hanging points on the upper part of the main board of the supporting bar, and several hanging points are evenly spaced at the bottom; hoisting holes are provided at the corresponding upper and lower hanging points of the main board, and reinforcing ribs are provided on both sides of the main board. Weld lug plates on both sides between the two lifting points near the end of the main board of the supporting bar; welding forklift hole parts between the two hanging points on the upper part of the main board of the supporting bar.

The fork transport hole is bent into a U-shaped piece by using a 15mm-20mm steel plate.

The hoisting hole is embedded with an anti-wear sheath, and the two sides are welded and fixed with ring-shaped steel plates.

The main board of the support bar and the lug plates on both sides are made of Q345 steel plates.

The beneficial effect of the utility model is that the utility model has the advantages of simple structure, reasonable design, convenient loading, unloading and transportation, and is especially suitable for steel pipe operations with high requirements on operation quality. When using the support bar with the chemical fiber rope buckle for steel pipe hoisting operations, under normal circumstances, the lifting point on the main board can be selected according to the length of the cargo, and the double-hook operation can be performed by using the side lug plate lifting point hook to hang the rope buckle. ;Compared with the single pair of lifting point support rods used in the past, one is that there are several lifting points at the bottom of the main board, and the suitable length can be freely selected for operation; When supporting the bars, it is necessary to arrange special personnel to assist in placing them; the third is to avoid the occurrence of cargo crush damage and threats to safe production when double-hook hoisting. The support bar can adapt to more operation situations, has wider application, and has very remarkable application effect.

detailed description

Below in conjunction with accompanying drawing and preferred embodiment, the specific implementation mode, structure, feature provided according to the utility model are described in detail as follows:

As shown in Figure 1 and Figure 2, the multi-purpose support bar includes a main board 1, a reinforcing rib 2, a lug plate 3 and a forklift hole 4; There are two hanging points on the upper part of the main board 1 of the support bar, and several hanging points are evenly spaced at the bottom, and the lifting holes 5 are provided at the upper and lower hanging points of the main board 1; reinforcing ribs 2 are provided on both sides of the main board 1, and 32# slots can be used The steel is welded on both sides of the main board 1 as the reinforcement rib 2 in parallel, that is, the reinforcement rib 2 is fastened and welded to the main board 1 from both sides, so as to achieve the purpose of strengthening the lateral stability of the support bar 1 . The two lifting points near the end of the support bar main board 1, that is, the two sides between the two lifting holes 5 are respectively welded with the lifting lug plate 3; Between the two hoisting holes 5 is located in the middle of the support bar main board 1 . The upper and lower parts of the main board 1 are provided with hoisting holes 5 with the same diameter and specifications, that is, the upper and lower parts of the main board 1 are punched at intervals. It is set within the range of 500mm-700mm, and the appropriate spacing length can be selected according to the actual situation in the operation to connect the lower suspension system.

The hoisting hole 5 is embedded with an anti-wear sheath, and a 10mm thick annular steel reinforcement plate is welded on both sides to enhance the strength of the hoisting hole 5 .

Both the main plate 1 of the support bar and the lug plates 3 on both sides are made of Q345 steel plate.

As shown in Figure 2, the welding surface of the lug plate 3 is made and welded according to the contour shape of the main board 1 and the rib 2, and the outer side of the lug plate 3 is made into a smooth slope transition shape, which effectively prevents the upper corners from colliding with the hatch during operation.

The above-mentioned detailed description of the multi-purpose support bar for loading and unloading of the wharf with reference to the embodiment is illustrative rather than restrictive, and the shape, size and material selection of the design of the spreader can be changed according to the needs of the operation; therefore, without departing from the general concept of the utility model The following changes and modifications should belong to the protection scope of the present utility model.
