[0020] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Those skilled in the art can understand that although some embodiments herein include certain features included in other embodiments rather than other features, the combination of features of different embodiments means that it is within the scope of the present invention and forms different embodiments. For example, in the claims, any one of the claimed embodiments can be used in any combination.

[0022] The following refers to the attached Figure 1 to the attached Figure 4 Describe an auxiliary tooling and equipment for hoisting an export hose of the present invention.

[0023] This embodiment provides an auxiliary tooling for hoisting an export hose. As Figure 1 shown, the auxiliary tooling for hoisting an export hose includes a hoisting assembly 1. The hoisting assembly 1 includes a hoisting disc 11 and a plug-in member 12. A plurality of plug-in holes 13 are provided on the hoisting disc 11. The plug-in member 12 can pass through the plug-in holes 13 and be respectively connected to single knot pipes. A hoisting point 2 is provided on the hoisting disc 11 for connecting with a rigging to hoist a plurality of single knot pipes. A shackle can be directly and vertically installed at the top of the auxiliary tooling for hoisting an export hose, so that the hose can be hoisted vertically, with stable and safe force. At the same time, it is convenient for installation and disassembly, improving production efficiency and safety, reducing production costs, and having the value of popularization and application.

[0024] Optionally, the above plug-in member 12 is set as a bolt. The bolt selected in this embodiment is a flat head bolt. Since the connection part between the flat head and the screw rod is about 90°, the bottom of the flat head can be well pressed against the step of the waist-shaped hole, thus playing a good fixing effect. In other embodiments, bolts of other shapes can also be selected. Among them, according to the screw head, they can be divided into structures such as hexagon heads and round heads. Specifically, because hexagon heads have the advantages of being convenient for fastening and disassembling and not easily slipping, they are widely used for fixing and pressing the pressing plates in the industrial field. And hexagon heads also have a strong anti-torsion effect, so when the load is strong, hexagon heads may need to be considered; round heads have the advantages of insulation, non-magnetic, corrosion resistance, beauty, and never rusting, and are mainly used for fixing and pressing the pressing plates in the medical machinery industry, aviation and other fields. Therefore, in the actual working process, it can be selected according to different situations, and other embodiments will not be elaborated too much.

[0025] Furthermore, as Figure 1 shown, the plug-in member 12 can pass through different plug-in holes 13 from both sides of the hoisting disc 11 to be respectively connected to different single knot pipes.

[0026] Specifically, for the external output hose hoisting auxiliary tooling, both ends of the single-section pipe structure are flanges. Usually, after being extended on the onshore operation line, it is vertically lifted by a shore crane and then coiled around the external output drum. The end of the external floating hose is an open flange, and there is no special hoisting tool in the market. Generally, a shackle or a snap ring is sleeved on the flange hole for hoisting. However, in this process, the shackle is subjected to uneven hoisting forces, which easily causes deformation or collision of the flange end of the external output hose. Through the connectors 12 at both ends, adjacent single-section pipe structures can be well connected and fixed, thereby improving stability and overcoming the defect of uneven force in the existing hoisting method.

[0027] Furthermore, as shown in Figure 1 , Figure 2 and Figure 4 , the lining of the hoisting disc 11 is circular, and the insertion holes 13 are evenly arranged in a circular array centered on the center of the circular hoisting disc 11; the hoisting points are set on the side away from the connection between the hoisting disc 11 and the single-section pipe; a blind plate 3 is arranged on the hoisting disc 11, and the hoisting points are set on the blind plate 3; the hoisting points are set in a ring shape and fixed to the blind plate 3 through cross-shaped rib plates. The above structure avoids the quality hazards caused by deformation or collision of the flange end of the external output hose due to uneven hoisting forces on the shackle in the original way during the hoisting and installation process of the hose, solves the dilemma of hanging and removing the hoisting shackle, reduces the production cost, and improves the construction efficiency and safety.

[0028] As a preferred embodiment, as shown in Figure 1 , Figure 3 and Figure 4 , the end face of the blind plate 3 on the side away from the hoisting disc 11 is set as an arc surface; a reinforcing rib 4 is arranged at the connection between the blind plate 3 and the hoisting disc 11; there are two groups of reinforcing ribs 4, and they are respectively located on both sides of the blind plate 3. By arranging the reinforcing rib 4 at the connection between the blind plate 3 and the hoisting disc 11, the hoisting disc 11 can be ensured to have a certain strength, thereby further improving the stability of the hoisting assembly 1. In addition, by setting one side of the blind plate 3 as an arc surface structure, the interference between the hoisting point and the blind plate 3 during installation is avoided, the installation efficiency of the staff is improved, and the installation space of the hoisting disc 11 is rationally utilized.

[0029] This embodiment provides an external output hose hoisting auxiliary device, including the above-mentioned external output hose hoisting auxiliary tooling. The external output hose hoisting auxiliary device further includes a plurality of single-section pipes, and adjacent two single-section pipes can be connected by using the external output hose hoisting auxiliary tooling. The external output hose hoisting auxiliary device avoids the quality hazards caused by deformation or collision of the flange end of the external output hose due to uneven hoisting forces on the shackle in the original way during the hoisting and installation process of the hose, solves the dilemma of hanging and removing the hoisting shackle, reduces the production cost, and improves the construction efficiency and safety.

[0030] It should be noted that when the external output hose hoisting auxiliary equipment in this embodiment uses the above-mentioned external output hose hoisting auxiliary tooling for hoisting operations, the following steps are usually involved: 1. Provide an external output hose hoisting auxiliary tooling, which is in the structure of a blind flange lifting lug as a whole. Among them, the lower end is a circular lifting plate with evenly distributed holes around it, which can cooperate with the hose end flange and be fastened with fasteners; 2. Weld an ear-type lifting point 2 at the upper end and fix it on the blind plate 3 with a cross-shaped rib plate. The ear-type lifting point 2 can cooperate with the shackle pin, and then a sling is hung above to hoist the floating hose as a whole; 3. Connect and fix the lower part of the hose and the upper part of another hose with bolts, and so on. When hoisting, only need to lift the tooling above the first hose to hoist the whole section of the hose.

[0031] 4. A shackle can be directly and vertically installed at the top of the external output hose hoisting auxiliary tooling, so that the hose can be hoisted vertically, with stable and safe force. At the same time, it is convenient for installation and disassembly, improves production efficiency and safety, reduces production costs, and has the value of popularization and application.
