DETAILED DESCRIPTION

[0024] In order to make the purpose, 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 in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0025] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0027] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" 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 direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] Please refer to Figure 1, this embodiment provides a pipeline lifting auxiliary device 100, which includes a first traction beam 110 and a second traction beam 120. Support components 130 are respectively fixedly connected to the first traction beam 110 and the second traction beam 120. The first traction beam 110 and the second traction beam 120 are slidably connected so that the two support components 130 approach or separate from each other. The support components 130 are used to support and bear the weight of the pipeline.

[0029] Specifically, the embodiments of the present application do not specifically limit the setting forms of the first traction beam 110 and the second traction beam 120. For example, the first traction beam 110 can be made of a rectangular plate or a circular plate, as long as it can ensure the required load-bearing weight and avoid deformation under force during the lifting process, which may affect normal use.

[0030] By slidably connecting the first traction beam 110 and the second traction beam 120, during the preparation work before lifting the pipeline, the first traction beam 110 and the second traction beam 120 are separated from each other, so that the support components 130 fixedly connected to the first traction beam 110 and the second traction beam 120 can be inserted into the pipeline. Then, the first traction beam 110 and the second traction beam 120 are made to approach each other to prevent the support components 130 from loosening from the pipeline. During the lifting process, the support components 130 are in force contact with the inner wall of the pipeline, so that the pipeline is supported by the support components 130 and is lifted to a specific position together with the pipeline lifting auxiliary device 100. At the same time, adopting the above form is beneficial to improving the applicability of the pipeline lifting auxiliary device 100 to adapt to pipelines of different lengths and is beneficial to reducing the transportation cost.

[0031] The pipeline lifting auxiliary device 100 provided by the embodiments of the present application plays a role in supporting and bearing the weight during the pipeline lifting process through the first traction beam 110 and the second traction beam 120. By slidably connecting the first traction beam 110 and the second traction beam 120, the first traction beam 110 and the second traction beam 120 can approach or separate from each other. Since support components 130 are respectively fixedly connected to the first traction beam 110 and the second traction beam 120, when the first traction beam 110 and the second traction beam 120 slide relative to each other, the two support components 130 are driven to approach or separate synchronously, so that the support components 130 can be clamped in the pipeline during lifting and are in contact with the pipeline during the lifting process, providing the required supporting force for the lifting of the pipeline. After being lifted to a specific position, the support components 130 can be taken out of the pipeline. The whole process is simple and convenient, without the need to wind the pipeline with a lifting rope or other forms. The pipeline lifting auxiliary device 100 provided by the embodiments of the present application ensures the stability of the pipeline hoisting, prevents the pipeline from shaking and falling during the hoisting process, can improve the reliability of the pipeline during lifting, and improves the safety during the lifting process.

[0032] Such as Figure 1As shown, lifting components 140 are respectively and fixedly connected to the first towing beam 110 and the second towing beam 120. The lifting components 140 are located outside the supporting components 130 and are used for auxiliary lifting of the pipeline.

[0033] Specifically, by respectively and fixedly connecting the lifting components 140 to the first towing beam 110 and the second towing beam 120, while the supporting components 130 support and bear the weight of the pipeline, they play an auxiliary lifting role for the pipeline. During the lifting process, the supporting force of the supporting components 130, the gravity of the pipeline itself, and the lifting force of the lifting components 140 are balanced, and the supporting components 130 and the lifting components 140 act together, so that the stress points of the pipeline are dispersed, avoiding the problem of excessive stress concentration and cracking during the lifting of the pipeline, which is beneficial to improving the safety during the lifting process.

[0034] As Figure 1 shown, the supporting components 130 include first connecting columns 132 and fixing seats 134 arranged at one end of the first connecting columns 132. The ends of the first connecting columns 132 far from the fixing seats 134 are respectively and fixedly connected to the first towing beam 110 and the second towing beam 120, and the two fixing seats 134 are arranged opposite to each other towards the center.

[0035] Specifically, when the two supporting components 130 are arranged opposite to each other, they are respectively and fixedly connected to the first towing beam 110 and the second towing beam 120 through the first connecting columns 132. When sliding between the first towing beam 110 and the second towing beam 120, the first connecting columns 132 are driven to approach or move away from each other. Among them, the embodiment of the present application does not specifically limit the setting form of the first connecting columns 132. For example, the first connecting columns 132 are perpendicular to the first towing beam 110, or the first connecting columns 132 and the second towing beam 120 have a preset included angle (such as 75°), as long as stable supporting force can be ensured. By arranging the two fixing seats 134 opposite to each other towards the center, during the process of the two first connecting columns 132 approaching each other, the fixing seats 134 can be clamped with the inner wall of the pipeline to realize the supporting effect during lifting.

[0036] As Figure 1 shown, the fixing seat 134 includes a support plate 1342 fixedly connected to the first connecting column 132 and a resisting block 1344 arranged on the support plate 1342. The resisting block 1344 is used for resisting against the inner wall of the pipeline.

[0037] Specifically, the support plate 1342 and the first connecting column 132 can be connected by welding or by fasteners, as long as the stability of the connection can be guaranteed. The abutment block 1344 provided on the support plate 1342 can be a rigid member, such as an iron block, or an elastic member 1426, such as rubber. When rubber is used, the hardness between the abutment block 1344 and the pipeline can be reduced, which is beneficial to protecting the pipeline. In addition, a reinforcing rib can be provided on the side of the support plate 1342 away from the abutment block 1344, which is beneficial to improve the strength of the support plate 1342 and avoid deformation due to force when lifting the pipeline.

[0038] like Figure 2 As shown, a sliding rod 112 is provided on the first traction beam 110, and a sliding groove 122 is correspondingly provided on the second traction beam 120. A baffle 114 is provided at the cantilever end of the sliding rod 112, and the baffle 114 can be clamped with the inner wall of the sliding groove 122, and positioning holes are respectively provided on the sliding rod 112 and the second traction beam 120 for positioning the first traction beam 110 and the second traction beam 120.

[0039] Specifically, the slide bar 112 provided on the first traction beam 110 and the corresponding slide groove 122 provided on the second traction beam 120 can make the slide bar 112 and the slide groove 122 slide together, so as to achieve the approach or distance between the first traction beam 110 and the second traction beam 120. In addition, the slide groove 122 can be in the form of a stepped groove, so that the baffle 114 provided at the cantilever end of the slide bar 112 can be clamped with the inner wall of the slide groove 122 to prevent the first traction beam 110 and the second traction beam 120 from being loosened.

[0040] It should be noted that a cover plate can be provided at the position where the second traction beam 120 is provided with the slide groove 122, so that after the slide bar 112 is matched with the slide groove 122, the cover plate is fastened and fixed to form a stable connection relationship. In addition, positioning holes are respectively provided on the slide bar 112 and the second traction beam 120. When the pipeline is clamped, the slide bar 112 and the slide groove 122 are relatively slid, and the positioning holes on the slide bar 112 and the second traction beam 120 correspond to each other. At this time, the relative position between the first traction beam 110 and the second traction beam 120 can be stabilized by inserting a pin into the positioning hole, so as to avoid the first traction beam 110 and the second traction beam 120 from slipping during the lifting process, which is conducive to improving the safety during use.

[0041] like Figure 3 As shown, the lifting assembly 140 includes a second connecting column 142 and a bracket 144 elastically connected to the second connecting column 142, and the bracket 144 is used to abut against the outer wall of the pipeline.

[0042] Specifically, through the second connecting column 142 and the bracket 144 elastically connected to the second connecting column 142, during the hoisting process of the pipeline, it can play an auxiliary positioning role, avoiding the situation of large-scale shaking of the pipeline due to the rotation direction or sudden pause during the hoisting process, which is beneficial to ensuring the safety during the hoisting process.

[0043] Please continue to refer to Figure 3 , the bracket 144 includes a connecting arm 1442 and a bearing plate 1444 arranged on the connecting arm 1442. The two bearing plates 1444 are arranged opposite to each other towards the center, and an arc-shaped cushion plate 1446 is arranged on the bearing plate 1444.

[0044] Specifically, during the relative sliding process of the first traction beam 110 and the second traction beam 120, the bracket 144 moves synchronously with the support assembly 130. Among them, the support assembly 130 is used to realize the acting force of supporting and lifting the pipeline by abutting against the inner wall of the pipeline. The bracket 144 abuts against the outer wall of the pipeline and plays a role of lifting during the hoisting process of the pipeline. In this way, the force on the pipeline can be dispersed, and it is beneficial to ensure the stability during the hoisting process of the pipeline. By arranging the arc-shaped cushion plate 1446 on the bearing plate 1444, it is beneficial to better fit with the outer wall of the pipeline during lifting, further improving the stability during lifting.

[0045] As Figure 3 and Figure 4 shown, a sliding rod 1443 is further arranged on the connecting arm 1442. A limit block 1445 is arranged at the cantilever end of the sliding rod 1443. A receiving groove 1422 is arranged on the second connecting column 142. The sliding rod 1443 is arranged in the receiving groove 1422. An end cover 1424 is arranged at the notch of the receiving groove 1422. An elastic member 1426 is sleeved on the sliding rod 1443. The two ends of the elastic member 1426 respectively abut against the end cover 1424 and the limit block 1445.

[0046] Specifically, a cover plate can be arranged at the position where the second connecting column 142 is provided with the receiving groove 1422. After the sliding rod 1443 and the receiving groove 1422 form a fit, the cover plate is buckled and fixed to form a stable connection relationship. The elastic member 1426 arranged on the sliding rod 1443 can be a spring piece or a compression spring. In the initial state (that is, the state where the connecting arm 1442 is not stressed), between the first connecting column 132 and the connecting arm 1442 is as Figure 4 shown in the state. When receiving the gravity of the pipeline, the connecting arm 1442 is stressed and slides in the direction away from the second connecting column 142, and the elastic member 1426 is stressed and compressed and deformed. The acting force that enables the elastic member 1426 to recover its elastic deformation forms an abutting effect with the pipeline, which is beneficial to ensuring the stable limit of the pipeline and avoiding random shaking during the hoisting process of the pipeline.

[0047] AsFigure 3 and Figure 4 As shown in Figure 4 , the second connecting column 142 is provided with a first ear plate 1428, and a second ear plate 1448 is correspondingly provided on the connecting arm 1442. A through hole 1248a is provided on the first ear plate 1428, and a connecting rod 1448a is provided on the second ear plate 1448. The connecting rod 1448a can pass through the through hole 1248a and slide relative to the first ear plate 1428. A limiting member 1449 is further provided on the connecting rod 1448a for limiting the sliding distance between the connecting rod 1448a and the first ear plate 1428.

[0048] Specifically, during the lifting process, the specifications of the lifted pipes may be different, and there are also certain differences in the wall thickness and aperture of the pipes. By providing the first ear plate 1428 on the second connecting column 142 and correspondingly providing the second ear plate 1448 on the connecting arm 1442, when the force borne by the bracket 144 is too large, the first ear plate 1428 and the second ear plate 1448 can share the force, avoiding damage to the pipe lifting auxiliary device 100 due to excessive force. Among them, the connecting rod 1448a is provided with a thread, and the limiting member 1449 can be a nut. In the actual use process, the sliding distance between the connecting rod 1448a and the first ear plate 1428 can be determined by the matching position between the thread and the nut, so as to be applicable to pipes of different specifications and provide stable support.

[0049] As Figure 1 shown, lifting lugs 150 are respectively provided on the first towing beam 110 and the second towing beam 120.

[0050] Specifically, during the lifting process, the lifting rope can be connected to the lifting lug 150, realizing stable lifting and laying of the pipe by the crane through the pipe lifting auxiliary device 100, avoiding the problems that when using the lifting rope to wind and lift, the winding of the rope is not tight or asymmetric, which easily causes the pipe to shake or even fall during the lifting process, being beneficial to improving the stability of pipe lifting, preventing the pipe from shaking and falling during the lifting process, and improving the work safety of workers.

[0051] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
