Description

Technical Field

[0001] This utility model belongs to the technical field of polyurethane insulation pipe production equipment, specifically relating to a transfer device for polyurethane insulation pipe production. Background Technology

[0002] In the production process of polyurethane insulated pipes, after the inner pipe and outer protective pipe are assembled and filled with polyurethane foam, a crane is needed to lift the entire assembly off the workbench for transfer and loading. Given the high cost and significant footprint of cranes, traditional methods often require two cranes to ensure smooth material handling, transfer, and loading, which undoubtedly increases the cost burden.

[0003] In view of this, this utility model designs a transfer device specifically customized for the production of polyurethane insulation pipes. After the insulation pipes are assembled, this device can directly realize the integrated operation of unloading and transfer, significantly improving the transfer efficiency in the production process and effectively reducing the dependence on high-cost crane equipment, thereby achieving the goal of controlling production costs.

[0004] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] This utility model integrates the assembly platform and transfer vehicle of polyurethane insulation pipes into a detachable structure. This design allows for immediate unloading and transfer operations after assembly, significantly enhancing the equipment's flexibility. It not only accelerates the unloading process but also eliminates reliance on cranes, simplifying the operation process, and its simple structure reduces manufacturing costs. The detachable mounting frame is equipped with casters, greatly facilitating the movement and transfer of the insulation pipes and improving transfer efficiency.

[0017] 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.

[0018] Example

[0019] Please see Figure 1-2 This utility model provides the following technical solution: a transfer device for the production of polyurethane insulation pipes, including a support 1, with a base 11 welded inside the support 1, and the base 11 adopts a symmetrical layout. Between the two symmetrically arranged bases 11, a rotatable positioning bracket 2 is provided, with a V-shaped cross-section to ensure the stability of the insulation pipe placement, while one edge of the V-shape abuts against the support 1. A cylinder 3 is equipped on one side of the positioning bracket 2, the cylinder body of the cylinder 3 being rotatably connected to the support 1, and its output end being connected to one side of the positioning bracket 2 to achieve the function of pushing the positioning bracket 2 to flip. A transfer structure is installed on the other side of the support 1 located on the positioning bracket 2. The main body of this transfer structure is a mounting frame 4, with casters 12 evenly distributed at its bottom for flexible movement. A fixed railing 5 is fixedly welded to one side of the mounting frame 4 to enhance safety, while a movable railing 6 is flexibly connected to the other side via a hinge to prevent the insulation pipe from falling during transfer. In addition, both ends of the fixed railing 5 are equipped with rotatable railings 7. One end of the railing 7 is detachably connected to the end of the movable railing 6. At the same time, the movable railing 6 and the bracket 1 are also detachably connected, which makes it convenient for the railing 7 and the movable railing 6 to be laid flat and connected to the bracket 1.

[0020] To facilitate the connection between the bracket 1 and the mounting frame 4, in this embodiment, as a preferred technical solution of the present invention, the bottom of the bracket 1 is uniformly welded with legs 8, the casters 12 and legs 8 are at the same height, and the bottoms are on the same horizontal plane.

[0021] To facilitate the connection between the railing 7 and the movable railing 6 and to fix the movable railing 6, in this embodiment, as a preferred technical solution of the present invention, a hook 9 is provided at one end of the railing 7 and a hook 10 is fixed at the end of the movable railing 6. The one end of the railing 7 and the end of the movable railing 6 are detachably connected by the hook 9 and the hook 10.

[0022] To facilitate quick and easy assembly and disassembly of the movable railing 6 and the bracket 1, in this embodiment, as a preferred technical solution of the present invention, the movable railing 6 and the bracket 1 are detachably connected by a pin.

[0023] In summary, based on the technical solution of this utility model, in actual operation, the outer protective tube is first securely hoisted into the positioning bracket 2 using a crane. Then, the inner tube is inserted and polyurethane foam is injected. Next, the positioning bracket 2 is flipped using the driving force of the cylinder 3, causing its bottom to rotate along the rotation point of the support 11. This allows the polyurethane insulation tube inside the positioning bracket 2 to roll along the other side of the V-shaped positioning bracket 2 to the bracket 1 under gravity, and finally roll onto the surface of the mounting frame 4. On the surface of the mounting frame 4, the fixing rails 5 effectively block the insulation tube, preventing it from continuing to roll.

[0024] Next, disconnect the fixing pin connection between one side of the movable railing 6 and the bracket 1, and vertically erect the movable railing 6 using the hinge. At this time, use the hook 9, which is rotatably connected to the end of the fixed railing 5 and the end of the railing 7, to hang it on the hook 10 of the movable railing 6, thereby securing the movable railing 6 and ensuring that the polyurethane insulation pipe will not roll off during transportation.

[0025] Finally, the support frame 4 is moved to the insulation pipe storage point using the casters 12 at the bottom for unloading. After unloading, the support frame 4 is pushed back to the bracket 1 and reconnected to continue carrying and transporting the newly produced polyurethane insulation pipe.

[0026] Finally, it should be noted that, in this utility model, unless otherwise explicitly specified and limited, the terms "installation," "setting," "connection," "fixing," "screw connection," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
