Description

Technical Field

[0001] This utility model relates to the field of material transportation technology, and in particular to a retractable pipeline conveying device. Background Technology

[0002] In the chemical and pharmaceutical industry, many gaseous and liquid materials are stored in raw material tanks for transportation due to their advantages such as large storage capacity and convenient transportation. However, when the materials in the tanks need to be used, the large volume, high weight, and high pressure of the raw material tanks make unloading, especially changing to different raw material tanks, quite difficult.

[0003] Currently, changing raw material tanks often involves using multiple pieces of equipment, such as cranes and tank-changing trucks, which is costly, difficult, and requires multiple operators to work together. In general, existing technologies waste human and material resources and pose safety hazards. Utility Model Content

[0004] In view of this, in order to facilitate the replacement of raw material tanks and allow transport vehicles to drive as close as possible to the storage location, this utility model proposes a multi-directional adjustable retractable pipeline conveying device, including a transport device 1, an auxiliary power device 4, and a support device 15. The main body of the transport device 1 is composed of multiple conveying pipes 5 connected end to end. Each conveying pipe 5 has a curved pipe, and the connection between adjacent conveying pipes 5 is provided with a joint 6. The conveying pipes 5 can move around the joint 6, and each connecting joint 6 can provide rotation in that direction. The rear end of the transport device 1 is connected to the support device 15. The upper end of the column 17 is connected to the first rotating mechanism 19, and the lower end of the column 17 is connected to the discharge pipe 3 through the second rotating mechanism 24. The first rotating mechanism 19 and the second rotating mechanism 24 are both first bearing structures, used to realize the free rotation of the entire transport device 1 around the first rotating mechanism 19, so that it can move away from the raw material tank. The auxiliary power device 4 provides additional power for adjusting the transport device 1, and the support device 15 provides support for the output end of the transport device 1, realizing the free retraction and extension of the device.

[0005] A multi-directional adjustable retractable pipeline conveying device includes a conveying device 1. The conveying device 1 has an inlet pipe 2 at its front end and an outlet pipe 3 at its rear end. Material enters the conveying device 1 through the inlet pipe 2 and is transported out through the outlet pipe 3. The device is characterized in that: the conveying device 1 is equipped with an auxiliary power device 4 to provide additional power for adjusting the conveying device 1; the main body of the conveying device 1 is composed of multiple conveying pipes 5 connected end-to-end; joints 6 are provided at the joints of adjacent conveying pipes 5, allowing the conveying pipes 5 to move around the joints 6, enabling free retraction and extension of the device; the rear end of the conveying device 1 is connected to a support device 15. The lower end of the device 15 is locked to the ground, and the upper end extends towards the transport device 1 with a crossbar 16. The free end of the crossbar 16 is provided with a first rotating mechanism 19. The last transport pipe 5 includes a column 17 perpendicular to the ground and a pipe 18 perpendicular to the column 17 and connected to the penultimate transport pipe 5. The upper end of the column 17 is connected to the first rotating mechanism 19, and the lower end of the column 17 is connected to the discharge pipe 3 through a second rotating mechanism 24. Both the first rotating mechanism 19 and the second rotating mechanism 24 are first bearing structures, which are used to enable the entire transport device 1 to rotate freely around the first rotating mechanism 19, so that it can move away from the raw material tank.

[0006] Furthermore, the support device 15 is also welded with a support rod 13. One end of the support rod 13 is welded to the lower end of the column 17 near the first rotating mechanism 19, and the other end is welded to the upper side of the last conveying pipe 5 in the horizontal direction to provide vertical tension.

[0007] Furthermore, the support device 15 can extend multiple crossbars 16 to provide support for different devices.

[0008] Furthermore, the discharge pipe 3 is an L-shaped pipe, and the connection between the discharge pipe 3 and the column 17 is perpendicular to the ground. A stabilizing block 20 is also connected below the support device 15. One end of the stabilizing block 20 is welded below the support device 15, and the other end is welded to one side of the discharge pipe 3 perpendicular to the ground, which is used to provide a second fulcrum for the rotation of the column 17.

[0009] Furthermore, the welding surface between the stabilizing block 20 and the conveying pipe 5 should be as large as possible to mitigate vibrations during material transportation and improve the stability of the conveying device 1.

[0010] Furthermore, each of the joints 6 is provided with an antistatic connecting piece 21. One end of the antistatic connecting piece 21 is connected to the conveying pipe 5 at one end of the corresponding joint 6, and the other end is connected to the conveying pipe 5 at the other end of the corresponding joint 6, so that multiple conveying pipes 5 are connected in series through multiple antistatic connecting pieces 21. An antistatic output device 22 is provided near the conveying device 1 of the discharge pipe 3. The output end of the antistatic output device 22 is grounded to eliminate static electricity generated during transportation and improve production safety.

[0011] Furthermore, the joint 6 includes a second bearing structure 23 and a first connecting member 7. The multiple conveying pipes 5 constituting the body of the conveying device 1 all have curved pipes. The connecting ends of adjacent conveying pipes 5 are connected to the second bearing structure 23. The two second bearing structures 23 are connected by the first connecting member 7. The first connecting member 7 is a first flange structure assembly. Each connecting joint 6 can provide rotation of the directional surface to ensure that the feed pipe 2 is aligned with the outlet of the raw material tank.

[0012] Furthermore, the first connector 7 is a bent pipe with a first flange structure at both ends.

[0013] In some embodiments, one end of the auxiliary power device 4 is connected to the bent pipe of the first connector 7 connected to the input end of the last conveying pipe 5, and the other end is connected to the body of the second-to-last conveying pipe 5. The auxiliary power device 4 is a hydraulic cylinder. When the conveying device 1 is assembled on the material tank, the spring in the hydraulic cylinder is in a slightly stretched state. When the conveying device 1 is disassembled, the spring in the hydraulic cylinder returns to its original position due to the lack of tension, thereby providing additional power during loading and unloading to assist in the retraction and lifting of multiple conveying pipes 5.

[0014] Furthermore, the curved pipe of the first connector 7, which is connected to the input end of the last conveying pipe 5 at one end of the auxiliary power device 4, is fixed by a pin-type fixing and is fixed to the support structure 14 by bolts. The curved pipe of the first connector 7 is welded to the bottom of the support structure 14.

[0015] Furthermore, the feed pipe 2 is connected to the raw material tank via a second connector 8, which is a second flange structure.

[0016] Furthermore, one end of the conveying pipe 6 near the feed pipe 2 is connected to the break valve 9 and the ball valve 10, and the other end is connected to the next conveying pipe 5 through the joint 6. The break valve 9 can prevent leakage accidents caused by accidental pipe breakage, and the ball valve 10 can control the material switch to achieve rapid opening and closing.

[0017] Furthermore, a handle 11 is welded to the outward extension of the curved pipe of the conveying pipe 6 near the feed pipe 2. The handle 11 is on the same straight line as the break valve 9 and the ball valve 10. A pull ring 12 is also welded next to the handle 11. The pull ring is perpendicular to the handle 11. By holding the pull ring 12 and the auxiliary handle 11, the weight of the conveying pipe 6 is supported by the pull ring 12, and the auxiliary handle 11 makes it easier for the operator to apply force for alignment and installation.

[0018] Furthermore, the inlet diameter of the feed pipe 2 is determined according to the outlet diameter of the raw material tank. The diameter of the rear end of the pipe is larger than the inlet diameter. The diameters of the multiple conveying pipes 5 in the first half of the conveying device 1 gradually increase to alleviate problems such as increased flow resistance and heat dissipation difficulties caused by excessive pressure in the raw material tank, thereby improving transportation efficiency and stability.

[0019] The beneficial effects of this utility model are as follows: This utility model proposes a multi-directional adjustable retractable pipeline conveying device, including a conveying device 1, an auxiliary power device 4, and a support device 15. The main body of the conveying device 1 is composed of multiple conveying pipes 5 connected end to end.

A handle 11 is welded to the outward extension of the curved section of the conveying pipe 5. The handle 11 is on the same straight line as the breakaway valve 9 and the ball valve 10.
