Description

Technical Field

[0001] The utility model relates to the technical field of transfer tools in large steel pipe workshops, in particular to a flatbed truck for preventing large steel pipes from rolling during transfer. Background Art

[0002] In the production process of large steel structure parts, many large bracket columns and support columns are inseparable from large-sized steel pipe parts. These steel pipe parts have large diameter sizes and are generally transferred between various processing equipment by large cranes in the workshop. However, for some local processing areas, after using the crane for hoisting and transfer, some position transfers are still required, and it is not convenient to use the crane. Moreover, large-sized pipe fittings are prone to safety accidents such as collision and dropping during hoisting, and the convenience is also insufficient. Therefore, it is necessary to design a safe transfer tool for ground transfer. Content of the Utility Model

[0003] The purpose of the utility model is to provide a flatbed truck for preventing large steel pipes from rolling during transfer in view of the above situation. The flatbed truck has simple structural improvement, flexible operation, and strong practicability.

[0004] The specific scheme of the utility model is: a flatbed truck for preventing large steel pipes from rolling during transfer, which has a vehicle bottom plate. Rolling walking wheels are arranged at the four corners of the bottom of the vehicle bottom plate. At least two sets of supporting structures are arranged on the vehicle bottom plate. The supporting structure has supporting beams longitudinally arranged on the vehicle bottom plate, and all the supporting beams are arranged parallel to each other. Two sets of relatively arranged and slidably adjustable block structures are arranged on each supporting beam.

[0005] Further, in the utility model, the block structure includes a clamping block, which is clamped on the corresponding supporting beam and can be slidably adjusted thereon. The clamping block and the side wall of the supporting beam are locked in real time through a locking bolt. A blocking block is welded to the clamping block.

[0006] Further, in the utility model, the blocking block is of an inclined plane structure. The two block structures on the same supporting beam are arranged relatively, and the inclined plane on the inclined plane structure faces the inner side.

[0007] Further, in the utility model, the clamping block is made of a rectangular channel steel. A locking bolt is threadedly installed on each of the two side walls of each clamping block, and the front end of the locking bolt abuts against the side wall of the corresponding supporting beam to achieve locking.

[0008] Further, in the utility model, the number of the supporting beams is 3 - 5. Each supporting beam is in the shape of a cuboid, and a concave arc supporting groove is arranged at the middle position of each supporting beam.

[0009] Furthermore, one end of the vehicle floor in the present utility model is also provided with a pushing handle, and the pushing handle is a double-bar handle or a doorframe-shaped handle.

[0010] Furthermore, the supporting beam in the present utility model is a hollow beam made of square tubes.

It is only for the convenience of describing the present utility model or simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed or operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0018] In the description of the present utility model, it should also be noted that unless otherwise clearly specified and limited, the terms "arrangement", "installation", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0019] See Figures 1 to 3 , the present utility model is a flatbed truck for preventing large steel pipes from rolling during transportation, which has a vehicle bottom plate 3. Further, one end of one side of the vehicle bottom plate in the present utility model is also provided with a pushing handle 7, and the pushing handle is a double-bar handle or a doorframe-shaped handle. The four corners of the bottom of the vehicle bottom plate are provided with rolling walking wheels 6, and at least two sets of supporting structures are arranged on the vehicle bottom plate. The supporting structure has a supporting beam 1 longitudinally arranged on the vehicle bottom plate, and all the supporting beams are arranged parallel to each other. Two sets of slidable and adjustable block structures are arranged oppositely on each supporting beam; further, the supporting beam in the present utility model is a hollow beam made of square tubes.

[0020] Further, in this embodiment, the block structure includes a clamping block 4, and the clamping block is clamped on the corresponding supporting beam and can slide and adjust thereon. The clamping block and the side wall of the supporting beam are locked in real time through a locking bolt 5, and a blocking block 2 is welded to the clamping block. Further, the blocking block in the present utility model is a bevel body structure, and the two block structures on the same supporting beam are arranged oppositely, and the bevel on the bevel body structure faces the inner side. Further, the clamping block in the present utility model is made of rectangular channel steel, and a locking bolt 5 is threadedly installed on each of the two side walls of each clamping block, and the front end of the locking bolt abuts against the side wall of the corresponding supporting beam to achieve locking. Further, the number of the supporting beams in the present utility model is 3 to 5, each supporting beam is in a cuboid shape, and a concave arc supporting groove 8 is arranged at the middle position of each supporting beam.

[0021] When the present utility model is actually used, it is used as a transportation trailer tool for large-sized steel pipes. Specifically:

[0022] First, hoist the large-sized steel pipe 9 to be transported and place it well in the concave arc supporting groove on the supporting beam. After placing it well, then adjust the two sets of block structures on each supporting beam, that is, move the corresponding clamping blocks from both sides to the middle until the bevel body structures on them simultaneously clamp the outer wall of the large-sized steel pipe from both sides, and then lock and fix the locking bolts at the same time. At this time, through the push of the doorframe-shaped handle by the staff, it can be relatively labor-saving to transport and move on the ground in the workshop. In actual use, this method is very safe and stable, and the operation and movement are also very flexible.

[0023] The utility model is an improvement based on an ordinary flatbed truck, which is used to transport large-sized steel pipes to achieve the purpose of safe and stable transportation, reduce the usage frequency of overhead cranes in the workshop, and can be transported on the workshop floor through manual operation.
