[0030] Embodiment 1:

[0031] Figure 1 and Figure 2 Fig. shows an embodiment of the pipeline hoisting device of the present utility model. The pipeline hoisting device of this embodiment includes a gantry 1 and a lifting and hoisting mechanism 2. The gantry 1 includes a top arm 11 and two support arms 12 respectively fixed at both ends of the top arm 11. The lifting and hoisting mechanism 2 is hung on the top arm 11 for hoisting the pipeline 4. Front diagonal braces 13 and rear diagonal braces 14 are respectively fixed on the front and rear sides of the support arm 12. Side support assemblies 3 are provided on the opposite sides of the two support arms 12. The top ends of the side support assemblies 3 are rotatably connected to the support arm 12 and can be telescopically adjusted in length.

[0032] During use, as Figure 2 shown, the two pipeline hoisting devices are arranged at intervals. Both ends of the pipeline 4 are respectively hoisted by the lifting and hoisting mechanisms 2 of the two pipeline hoisting devices. The pipeline 4 is hoisted by the lifting and hoisting mechanism 2 to achieve the alignment and installation of the pipeline 4. For this pipeline hoisting device, the front diagonal braces 13 and the rear diagonal braces 14 are respectively fixed on the front and rear sides of the support arm 12 of the gantry 1, and side support assemblies 3 are provided on the opposite sides of the two support arms 12. During use, auxiliary supports are respectively formed on the front and rear sides and the left and right sides of the gantry 1 through the front diagonal braces 13, the rear diagonal braces 14 and the side support assemblies 3 to prevent the gantry 1 from tilting sideways, improving the stability and safety. Moreover, the top ends of the side support assemblies 3 are rotatably connected to the support arm 12 and can be telescopically adjusted in length, facilitating the rotation and telescoping of the side support assemblies 3, adjusting the ground support position, and improving the adaptability.

[0033] Furthermore, in this embodiment, the side support assembly 3 includes a first support rod 31 and a second support rod 32 that are movably sleeved. The top end of the first support rod 31 is rotatably connected to the support arm 12. A locking member 33 for locking the two is provided between the first support rod 31 and the second support rod 32. When the locking member 33 releases the locking effect on the first support rod 31 and the second support rod 32, the first support rod 31 and the second support rod 32 can slide to adjust the total length. After the length is adjusted, the first support rod 31 and the second support rod 32 are locked by the locking member 33. The structure is simple and the adjustment is convenient.

[0034] Further, in this embodiment, locking holes 34 are arranged at intervals along the length direction on both the first support rod 31 and the second support rod 32. The locking member 33 passes through the corresponding locking holes 34 of the first support rod 31 and the second support rod 32 to lock the first support rod 31 and the second support rod 32. The structure is simple and convenient to manufacture. Preferably, the locking member 33 is a locking pin, a locking nail, etc.

[0035] Further, in this embodiment, the side support assembly 3 and the support arm 12 are rotatably connected by a connecting bolt 5. On the one hand, when the connecting bolt 5 is in an unlocked state, the side support assembly 3 can be rotated and adjusted relative to the support arm 12. On the other hand, when the connecting bolt 5 is in a locked state, it is difficult for the side support assembly 3 to rotate and adjust relative to the support arm 12, and the relative angle between the two can be locked.

[0036] Further, in this embodiment, the bottom ends of the support arm 12, its front diagonal brace 13 and its rear diagonal brace 14 are fixedly connected by a backing plate 15. The bottom ends of the support arm 12, its front diagonal brace 13 and its rear diagonal brace 14 are connected into one body by the backing plate 15, improving the stability of the overall structure.

[0037] Further, as Figure 1 shown, in this embodiment, the lifting and hoisting mechanism 2 includes a bearing block 21 and two lifting components 22. Connecting holes 211 are respectively arranged at both ends of the bearing block 21, and a bearing pipe groove 212 with an upward opening is arranged in the middle of the bearing block 21. The top ends of the two lifting components 22 are both hung on the top arm 11, and the bottom ends are respectively connected to the connecting holes 211 at both ends of the bearing block 21. When in use, the pipeline 4 is placed in the bearing pipe groove 212, and the bearing pipe groove 212 is adapted to the outer wall surface of the pipeline 4. On the one hand, the bearing pipe groove 212 has a limiting effect on the left and right movement of the pipeline 4, and bundling operation is not required. On the other hand, the pipeline is in adaptive contact with the bearing pipe groove 212, increasing the contact area, not prone to frictional movement, and with low noise.

[0038] Further, in this embodiment, two spaced-apart card slots 111 are arranged on the top arm 11, and the two lifting components 22 are respectively clamped in the two card slots 111. The lifting component 22 is clamped in the card slot 111 to prevent movement along the top arm 11, further improving the stability of the hoisting operation.

[0039] Further, in this embodiment, the lifting and hoisting mechanism 2 further includes a pipe fixing belt 23. Fixing components 24 are respectively arranged at both ends of the bearing block 21, and the pipe fixing belt 23 is connected between the fixing components 24 at both ends of the bearing block 21. On the one hand, the pipe fixing belt 23 can have a limiting effect on the upper surface of the pipeline 4, such as clamping the pipeline 4 by the pipe fixing belt 23 and the bearing pipe groove 212, further improving the stability of the pipeline 4 during hoisting. On the other hand, the pipe fixing belt 23 is detachably fixed to the bearing block 21 through the fixing component 24, which is convenient for disassembly and assembly and for placing the pipeline 4 on the bearing block 21. The fixing component 24 can be a screw, a bolt, etc.

[0040] Furthermore, in this embodiment, the lifting component 22 is a chain block or an electric hoist.

[0041] Embodiment Two:

The structure in this embodiment is basically the same as that of Embodiment One, except that: clamping slots 6 are provided at the bottoms of both ends of the bearing block 21, and rotating support rods 7 are hinged on both support arms 12. An adapting portion 71 for adaptively engaging with the corresponding clamping slot 6 is provided at the free end of the rotating support rod 7.

[0043] Before placing the pipeline, the rotating support rods 7 of the two support arms 12 can be rotated inwards first to respectively support on the clamping slots 6 at both ends of the bearing block 21. Specifically, the adapting portion 71 of the rotating support rod 7 is adapted to engage with the corresponding clamping slot 6 to form an upward supporting force on the bearing block 21, and then the pipeline 4 is placed in the pipe receiving groove 212 of the bearing block 21, thereby improving the stability and safety when placing the pipeline 4.

[0044] It should be noted here that the length of the rotating support rod 7 is set according to actual needs, as long as the adapting portion 71 is adapted to engage with the corresponding clamping slot 6 to form an upward supporting force on the bearing block 21.
