[0029] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with examples and drawings. The exemplary embodiments of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0030] In the following description, numerous specific details are set forth to provide a thorough understanding of the present invention. However, it will be apparent to one skilled in the art that these specific details are not necessarily required to practice the present invention. In other embodiments, well-known structures, circuits, materials, or methods are not described in detail to avoid obscuring the present invention.

Therefore, appearances of the phrases "one embodiment," "an embodiment," "an example," or "an example" in various places throughout this specification are not necessarily all referring to the same embodiment or example. Furthermore, the particular features, structures, or characteristics may be combined in one or more embodiments or examples in any suitable combinations and / or subcombinations. Furthermore, it will be understood by those of ordinary skill in the art that the figures provided herein are for illustrative purposes only and are not necessarily drawn to scale. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0032] In the description of the present invention, the terms "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "high", "low", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limiting the scope of protection of the present invention.

[0033] Example: like Figures 1-10 As shown, in a first aspect, the present invention provides a pipeline hoisting device, comprising a gantry module 100, a hoisting module 200 and a control module; The gantry module 100 forms a hoisting area, and the bottom surface of the hoisting area is divided into a material preparation area and a construction area arranged side by side. Accordingly, the material preparation area is used to place pipelines, and the construction area is used to bury pipelines; The lifting module 200 is slidably mounted on the gantry module 100 and is used to lift the pipes from the preparation area to the construction area; The control module is used to control the operation of the gantry module 100 and the lifting module 200, so that the gantry module 100 has a first workstation moving along the construction area and a second workstation stopping in a certain area; accordingly, the gantry module 100 has a moving function, and when the gantry module 100 is in the second workstation, the lifting module 200 works and lifts the pipeline.

[0034] The pipeline hoisting device is used to replace manual labor to complete the pipeline laying operation. Specifically, the staff first completes the relevant preparatory work, that is, the preparation area and the construction area are demarcated, the pipeline is placed in the preparation area, and the installation groove is excavated in the construction area; combined with actual projects, it can be seen that a certain length of installation groove is excavated according to the design drawings, and several pipelines are placed one by one along the direction of the installation groove. The installation groove and the pipeline are side by side and spaced apart to shorten the distance of pipeline lifting as much as possible.

[0035] Secondly, the pipe lifting device is used to complete the pipe lifting operation, that is, the control module controls the gantry module 100 to be in the first position, and the gantry module 100 moves to above the installation slot and the pipe. In other words, the installation slot and the pipe pass through the lifting area. The control module switches the gantry module 100 to the second position, and the gantry module 100 stops and improves the stability of the pipe lifting device. The control module controls the lifting module 200 to work, and the lifting module 200 slides along the gantry module 100 to above the pipe, and the lifting module 200 moves down and connects the pipe, and the lifting module 200 moves up again to lift the pipe; the lifting module 200 slides along the gantry module 100 to above the installation slot, and the lifting module 200 moves down until the pipe is placed in the installation slot, and the lifting module 200 releases the pipe and resets; thus, the lifting operation of one of the pipes is completed.

[0036] After the pipeline lifting operation is completed, the staff will carry out pipeline auxiliary operations, including but not limited to casing installation, anti-corrosion and insulation treatment, compensator installation, non-destructive testing, heat treatment, backfilling, interface treatment, etc. The staff can perform related operations according to the specific construction requirements, and this embodiment will not be repeated here.

[0037] Next, the control module switches the gantry module 100 to the first position. It moves along the length of the installation slot to the top of the next pipe. The control module then switches the gantry module 100 to the second position, stopping it. The control module then controls the lifting module 200 to lift the pipe again. This process is repeated multiple times to complete the pipe installation.

[0038] After all pipes are installed, the installation trench can be backfilled.

[0039] It is worth noting that after the pipe hoisting device completes the lifting operation of one pipe, if the lifting module 200 is required to complete the operation, the pipe hoisting device will not be moved to improve the efficiency of the pipeline auxiliary operation. Conversely, if the lifting module 200 is not required, the pipe hoisting device will move to the next construction location, clearing the space to avoid interference.

[0040] It is easy to understand that the control module can select any suitable existing model to achieve automatic construction while having a wide range of choices to adapt to different construction environments and requirements.

[0041] Based on this, the pipe lifting device effectively replaces manual labor, improving efficiency and shortening construction periods while also reducing worker workload and intensity. For field construction, shortened construction periods help reduce worker exposure time and improve worker safety; reduced labor intensity helps workers maintain focus, allowing them to promptly detect and avoid danger.

[0042] In addition, when the pipeline is lifted by the pipeline lifting device, the sudden falling of the pipeline is effectively avoided, the occurrence rate of construction accidents is reduced, the workers are protected, and the probability of damage to the pipeline is effectively avoided, which reduces the loss of building materials and helps save construction costs.

[0043] In one possible implementation, the portal module 100 includes a beam 101 and a column 102; Each end of the crossbeam 101 is connected to a column 102, and accordingly, there are two columns 102; the bottom surface of the crossbeam 101 is connected to the lifting module 200, and accordingly, the lifting module 200 can move back and forth along the bottom surface of the crossbeam 101; The lower end of the column 102 is provided with a sliding wheel 300 for moving the gantry module 100, and a rotatable cover plate 400 is provided on the outer peripheral surface of the lower end of the column 102; accordingly, when the gantry module 100 is in the first working position, the sliding wheel 300 extends outward to the bottom of the column 102, and the cover plate 400 is stored on the column 102; when the gantry module 100 is in the second working position, the sliding wheel 300 is retracted into the column 102, and the cover plate 400 rotates and is covered on the base surface.

[0044] Based on the above design, the portal module 100 is interconnected via a crossbeam 101 and two columns 102 to form a gantry structure. Retractable sliding wheels 300 are provided beneath the columns 102. Specifically, when the pipe-lifting device needs to be moved, that is, when the portal module 100 is in the first position, the sliding wheels 300 extend outward to facilitate movement. Conversely, when the pipe-lifting device does not need to be moved, that is, when the portal module 100 is in the second position, the sliding wheels 300 retract into the columns 102, increasing the contact area and friction coefficient between the columns 102 and the base surface, thereby improving the stability of the pipe-lifting device during lifting operations.

[0045] Furthermore, a cover plate 400 is provided on the column 102. When the gantry module 100 is in the second position, the cover plate 400 rotates and rests on the base surface, further increasing the contact area between the column 102 and the base surface, thereby further improving the stability of the pipe hoisting device during hoisting operations. Similarly, when the gantry module 100 is in the first position, the cover plate 400 rotates and disengages from the base surface to avoid obstructing the movement of the gantry module 100.

[0046] Alternatively, as Figure 2 and Figure 3 As shown, two cover plates 400 are provided and symmetrically arranged on both sides of the column 102. Based on this, multiple cover plates 400 can be provided to maximize the stability of the pipeline hoisting device during the hoisting operation.

[0047] It is easy to understand that the base surface can be any suitable construction location such as the ground, rock surface, etc.

[0048] In one possible implementation, the sliding wheel 300 includes a first driver, a transmission shaft 301 and a wheel body 302. The first driver is arranged on the column 102, and the output end of the first driver is connected to the wheel body 302 through the transmission shaft 301, so that the transmission shaft 301 can be lifted and lowered back and forth, so that the wheel body 302 can be extended outside the column 102 or retracted into the column 102.

[0049] Based on the above design, the first driver is used to provide power to drive the transmission shaft 301 to move back and forth, thereby controlling the position of the wheel body 302 relative to the column 102, thereby achieving the retraction and extension of the wheel body 302 relative to the column 102. In this way, the wheel body 302 can be positioned appropriately for the workstation where the gantry module 100 is located.

[0050] It is easy to understand that the first driver and the wheel body 302 can be selected from any suitable existing models, and the staff can make a selection based on the specific construction situation.

[0051] It is worth noting that when the wheel body 302 is located outside the column 102, the bottom surface of the column 102 is suspended in the air. When the wheel body 302 is retracted into the column 102, the bottom surface of the column 102 presses against the base surface. In other words, when the wheel body 302 is retracted into the column 102, the height of the gantry module 100 will decrease. Based on this, when the wheel body 302 is retracted into the column 102, it is important to control the speed of the wheel body 302 retraction and the synchronous retraction of the two wheel bodies 302 to prevent the gantry module 100 from shaking and ensure the stability of the gantry module 100 when switching workstations.

[0052] In one possible implementation, the cover plate 400 includes a plate body 401 and a support rod 402. One end of the plate body 401 is a hinged end connected to the column 102, and the other end of the plate body 401 is a free end detachably connected to the column 102. One end of the support rod 402 is connected to the column 102 via a first hinge seat 403, and the other end of the support rod 402 is connected to the plate body 401 via a second hinge seat 404. Accordingly, the first hinge seat 403 is slidably provided on the column 102. When the plate 401 rotates relative to the column 102, the first hinge seat 403 slides to rotate the support rod 402. The column 102 is provided with a clamping member 500 for clamping the first hinge seat 403 . Accordingly, when the plate 401 is placed on the base surface, the clamping member 500 clamps the first hinge seat 403 to fix the cover plate 400 .

[0053] Based on the above design, when the cover plate 400 rotates and covers the base surface, the plate body 401 contacts the base surface, and the support rod 402 moves with it and acts as a diagonal support to provide support for the cover plate 400.

[0054] The hinged end of the plate 401 is connected to a drive device, which provides power and enables the rotation of the plate 401. The free end of the plate 401 is connected to the column 102 via any suitable detachable connection method, such as a snap-fit ​​structure. Based on this, taking the snap-fit ​​structure as an example, when the plate 401 is retracted and closely attached to the column 102, the plate 401 is connected to the column 102 via the snap-fit ​​structure, thereby improving the reliability of the connection between the plate 401 and the column 102. When the plate 401 rotates and detaches from the column 102, the snap-fit ​​structure does not hinder the movement of the plate 401.

[0055] The support rod 402 is connected to the column 102 via a first hinge seat 403. When the panel 401 rotates and contacts the base surface, the first hinge seat 403 slides along the column 102, allowing the support rod 402 to rotate and adjust its angle. After the panel 401 contacts the base surface, the first hinge seat 403 moves to its limit position, at which point the first hinge seat 403 is fixed by a clamping member 500 to ensure the stability of the support rod 402. Conversely, when the panel 401 is retracted, the clamping member 500 disengages from the first hinge seat 403, facilitating its upward movement and preventing obstruction to the retraction of the panel 401.

[0056] The support rod 402 is connected to the plate body 401 via the second hinge seat 404 . As the plate body 401 rotates, the support rod 402 rotates relative to the second hinge seat 404 to cooperate with the sliding of the first hinge seat 403 , thereby adjusting the angle of the support rod 402 .

[0057] It is easy to understand that the first hinge seat 403 and the second hinge seat 404 can be constructed as any suitable structure, or any suitable existing model can be selected to rotate relative to the support rod 402 as the plate body 401 rotates, thereby adjusting the angle of the support rod 402.

[0058] In a possible implementation, the clamping member 500 includes a second driver, an intermediate frame 501 , a first clamping rod 502 , and a second clamping rod 503 ; The second driver is disposed in the column 102 , and the output end of the second driver is connected to the intermediate frame 501 to drive the intermediate frame 501 to move back and forth; The intermediate frame 501 is connected to a clamping rod, which includes a first clamping rod 502 and a second clamping rod 503 spaced apart above and below each other; The clamping member 500 has a first clamping position and a second clamping position through the movement of the intermediate frame 501. Accordingly, when the clamping member 500 is in the first clamping position, one end of the clamping rod abuts against the transmission shaft 301 of the sliding wheel 300 to limit the position of the sliding wheel 300; when the clamping member 500 is in the second clamping position, the other end of the clamping rod extends outward from the column 102 and forms a clamping groove for clamping the first hinge seat 403. Correspondingly, two limiting rings 303 are provided on the transmission shaft 301 of the sliding wheel 300 , and the clamping rod moves to above the limiting rings 303 and abuts against the limiting rings 303 to limit the position of the sliding wheel 300 .

[0059] Based on the above design scheme, the second driver is used to provide driving force to drive the intermediate frame 501 to move back and forth in the column 102, and the connecting rod connecting the intermediate frame 501 also moves accordingly; and the connecting rod includes a first connecting rod 502 and a second connecting rod 503 spaced apart above and below. When the connecting rod extends out of the column 102, the first connecting rod 502 and the second connecting rod 503 form a slot adapted to the first hinge seat 403, thereby fixing the position of the first hinge seat 403.

[0060] With respect to the sliding wheel 300, when the wheel body 302 is located outside the column 102, that is, the gantry module 100 is in the first movable position, the weight of the pipe hoisting device acts on the sliding wheel 300. Based on this, in order to reduce the pressure on the sliding wheel 300, and considering that the clamping member 500 can also be retracted into the column 102, the transmission shaft 301 of the sliding wheel 300 is connected by the clamping member 500, that is, the first clamping rod 502 and the second clamping rod 503 are respectively moved above the limit ring 303 and abut the corresponding limit ring 303, and the clamping member 500 is set in the column 102, so that the gravity is transmitted to the column 102 through the clamping member 500, thereby sharing the pressure of the sliding wheel 300.

[0061] At the same time, the use of the clamping member 500 for position limiting can also effectively fix the sliding wheel 300 outside the column 102, so that the gantry module 100 is stably in the first working position. In addition, the free end of the plate body 401 in the cover plate 400 is detachably connected to the plate body 401. When the clamping member 500 is extended, the first clamping rod 502 and the second clamping rod 503 move outward to collide with the plate body 401, thereby separating the plate body 401 from the column 102.

[0062] In other words, the reciprocating movement of the clamping member 500 can also be used for the work station switching of the gantry module 100, that is, when the clamping member 500 is retracted into the column 102, the clamping member 500 abuts against the sliding wheel 300 through the first clamping rod 502 and the second clamping rod 503; at this time, the wheel body 302 of the sliding wheel 300 is located outside the column 102, and the plate body 401 of the cover plate 400 is connected to the column 102. When the clamping member 500 extends outward from the column 102, the first clamping rod 502 and the second clamping rod 503 are both separated from the sliding wheel 300, and the sliding wheel 300 can retract the wheel body 302 into the column 102. The first clamping rod 502 and the second clamping rod 503 move outward to hit the plate body 401, so that the plate body 401 is separated from the column 102, so that the plate body 401 can rotate outward and contact the base surface. The first clamping rod 502 and the second clamping rod 503 also form a clamping groove for clamping the first hinge seat 403 to fix the cover plate 400.

[0063] The connecting member 500 forms a slot with a first latching rod 502 and a second latching rod 503, positioned one above the other. This slot secures the first hinged seat 403 within the slot. As can be seen from the movement, if the first latching rod 502 and the second latching rod 503 move outward simultaneously, the first hinged seat 403 moves downward and is blocked by the latching rod above, preventing the first hinged seat 403 from being inserted into the slot. Therefore, when the first latching rod 502 and the second latching rod 503 move outward, the lower one of the two first moves outside the column 102 to block the position of the first hinged seat 403, and the upper one then moves outside the column 102, thereby forming the slot and securing the first hinged seat 403.

[0064] In this regard, in one possible implementation, the first clamping rod 502 is located above the second clamping rod 503. The first clamping rod 502 is provided with two spaced-apart shaft sleeves 504, each of which has a clamping hole. Both sides of the intermediate frame 501 are provided with a clamping shaft 505 detachably connected to the clamping hole. The second clamping rod 503 is connected to the middle frame 501; When the intermediate frame 501 moves back and forth, the second clamping rod 503 moves with it. The intermediate frame 501 is connected to the shaft sleeve 504 via the clamping shaft 505 and drives the first clamping rod 502 to move. Correspondingly, when the clamping shaft 505 is separated from the shaft sleeve 504, the intermediate frame 501 moves and the first clamping rod 502 remains stationary, so that the first clamping rod 502 and the second clamping rod 503 generate relative motion. Correspondingly, the clamping member 500 also includes a telescopic rod 506 and a third driver 507. The telescopic rod 506 is used to separate the sleeve 504 and the clamping shaft 505. The third driver 507 is used to drive the end of the first clamping rod 502 to move outside the column 102 so that the first clamping rod 502 and the second clamping rod 503 form the clamping groove.

[0065] Based on the above design, when the second driver drives the intermediate frame 501 and the two connecting rods to move outward, the second connecting rod 503 connects to the intermediate frame 501, and the second connecting rod 503 moves synchronously with the intermediate frame 501. The first connecting rod 502 is detachably connected to the connecting shaft 505 of the intermediate frame 501 via the shaft sleeve 504. When the shaft sleeve 504 is connected to the connecting shaft 505, the first connecting rod 502 moves synchronously with the intermediate frame 501. When the shaft sleeve 504 is disengaged from the connecting shaft 505, the first connecting rod 502 remains relatively stationary, so that the first connecting rod 502 and the second connecting rod 503 move asynchronously, ensuring that the second connecting rod 503 moves outward to the outside of the column 102 first, and then the first connecting rod 502 moves outward to the outside of the column 102.

[0066] Specifically, if Figure 4As shown, when the clamping member 500 is retracted and abuts the sliding wheel 300, the clamping shaft 505 is inserted into the shaft sleeve 504 located on the inside. When the clamping member 500 moves outward, the first clamping rod 502 and the second clamping rod 503 move outward synchronously until the shaft sleeve 504 abuts the telescopic rod 506. At this time, the intermediate frame 501 continues to move outward, and the second clamping rod 503 moves outward synchronously. As for the first clamping rod 502, due to the obstruction of the telescopic rod 506, the first clamping rod 502 remains relatively stationary until the clamping shaft 505 is inserted into the shaft sleeve 504 located on the outside. For details, see Figure 5 .

[0067] At this point, the first latching rod 502 is reconnected to the intermediate frame 501, and the telescopic rod 506 retracts to prevent it from obstructing the outward movement of the connecting member 500. The intermediate frame 501 continues to move, thereby driving the first latching rod 502 and the second latching rod 503 to move outward synchronously until the second latching rod 503 moves outside the column 102. At this point, the first latching rod 502 is located inside the column 102 and connected to the third actuator 507. When the first hinged seat 403 presses against the second latching rod 503, the third actuator 507 drives the first latching rod 502 outward, forming a slot that secures the first hinged seat 403.

[0068] Furthermore, when the clamping member 500 is retracted and separated from the first hinge seat 403 , the intermediate frame 501 moves inward to drive the first clamping rod 502 and the second clamping rod 503 to retract inward until they abut against the sliding wheel 300 .

[0069] Alternatively, as Figure 7 As shown, by controlling the spacing between the two sleeves 504, when the third actuator 507 drives the first latching rod 502 outward to form a slot, the inner sleeve 504 on the first latching rod 502 connects to the latching shaft 505 of the intermediate frame 501. When the intermediate frame 501 moves inward, the first and second latching rods 502 and 503 move inward synchronously. This ensures that the two latching rods are connected to the sliding wheel 300 in a consistent manner, ensuring a more even force distribution on the latching member 500 and extending its service life.

[0070] In one possible implementation, the lifting module 200 includes a lifting box 210 and a lifting structure; the upper end of the lifting box 210 is slidably set on the gantry module 100, and the lower end of the lifting box 210 is connected to the lifting structure, which is used to connect the pipeline.

[0071] Based on the above design, the lifting box 210 is used to connect the gantry module 100 and the lifting structure. The lifting box 210 has a lifting function to drive the lifting structure up and down, thereby moving the pipeline. The lifting structure can be any suitable existing structure such as a hook or claw to better adapt to different lifting operations.

[0072] In one possible implementation, the hoisting box 210 includes an outer box 201 , an inner box 202 , and an intermediate box 203 ; The upper end of the outer box 201 is connected to the gantry module 100, and the lower end of the outer box 201 is open. A downwardly extending threaded shaft 204 is provided on the bottom surface of the top plate of the outer box 201. The middle box 203 and the inner box 202 are sequentially inserted into the outer box 201 from the outside to the inside. The upper end of the middle box 203 is connected to the threaded shaft 204 via the middle plate 205. The middle box 203 is connected to the outer box 201 and the inner box 202 via a gear rack mechanism 600. Correspondingly, when the threaded shaft 204 rotates, the inner box 202 and the middle box 203 rise and fall synchronously and extend and retract relative to each other.

[0073] Based on the above design, in the hoisting box 210, the upper end of the outer box 201 is slidably connected to the gantry module 100, and the lower end of the outer box 201 is open to facilitate the installation of the inner box 202 and the intermediate box 203, which also provides space for the lifting and lowering of the inner box 202 and the intermediate box 203. The inner box 202 is used to connect to the lifting structure, so that the lifting structure rises and falls with the movement of the hoisting box 210. The intermediate box 203 is used to connect the outer box 201 and the inner box 202. Accordingly, the gear rack mechanism 600 plays a connecting and transmission role. When the threaded shaft 204 rotates, the inner box 202 and the intermediate box 203 are synchronously raised and lowered and relatively extended, thereby increasing the lifting distance of the hoisting box 210.

[0074] It is worth noting that the middle box 203 is based on the outer box 201 and moves downward relative to the outer box 201; when the middle box 203 moves, the inner box 202 also moves downward synchronously, and the inner box 202 is based on the middle box 203 and moves downward relative to the middle box 203. Figure 9 As shown, the inner box 202 descends a greater distance than the middle box 203 , thereby achieving the purpose of increasing the lifting distance of the hoisting box 210 .

[0075] In one possible implementation, when there is only one intermediate box 203, the inner box 202, the intermediate box 203 and the outer box 201 are sequentially arranged from the inside to the outside; the upper end of the intermediate box 203 is connected to the threaded shaft 204 through the intermediate plate 205, and transmission gears 601 are respectively provided on both sides of the intermediate box 203, and matching transmission racks 602 are respectively provided on the outer box 201 and the inner box 202, and the two sides of the transmission gear 601 are respectively engaged with the adjacent transmission racks 602; accordingly, the transmission gear 601 and the transmission rack 602 constitute the gear rack mechanism 600.

[0076] In another possible implementation, when there are multiple intermediate boxes 203, the inner box 202, multiple intermediate boxes 203 and the outer box 201 are arranged in sequence from the inside to the outside; the intermediate box 203 located on the outermost side is connected to the threaded shaft 204 through the intermediate plate 205; among the three adjacent boxes, the box located in the middle is provided with a transmission gear 601, and the boxes located on both sides are respectively provided with matching transmission racks 602, and the two sides of the transmission gear 601 are respectively engaged with the adjacent transmission racks 602; accordingly, the transmission gear 601 and the transmission rack 602 constitute the gear rack mechanism 600.

[0077] Based on the above design, the total number of boxes is not less than three, and there is at least one middle box 203. As for the gear transmission mechanism, among the three boxes arranged in sequence, the middle box is provided with a transmission gear 601, and the boxes on both sides are provided with matching transmission racks 602. Figure 10 According to the above method, with the outer box 201 as the reference, every three boxes form a transmission group and the gear rack mechanism 600 is set inward layer by layer to realize the connection between the boxes.

[0078] It is easy to understand that when the same housing is included in different transmission groups, the rack and pinion mechanisms 600 of the different transmission groups should be staggered on the same housing to avoid mutual interference.

[0079] It is worth noting that the greater the number of intermediate boxes 203, the longer the lifting distance, but the more complex the overall structure. Under the condition that the size of the outer box 201 remains unchanged, the structural strength of each box will also decrease. Conversely, the fewer the number of intermediate boxes 203, the shorter the lifting distance, but the simpler the overall structure. Under the condition that the size of the outer box 201 remains unchanged, the structural strength of each box can be greater. Therefore, under the condition that the structural strength of the hoisting box 210 meets the use requirements, the staff can appropriately increase or decrease the number of intermediate boxes 203 according to actual conditions.

[0080] In a second aspect, the present invention provides a pipeline hoisting method using the pipeline hoisting device, comprising the following steps: S10: The material preparation area and the construction area are demarcated, pipes are placed in the material preparation area, and installation trenches are excavated in the construction area; S20: The pipe hoisting device hoists one of the pipes into the installation slot; S30: Pipeline auxiliary operations; S40: Repeat the pipe hoisting device hoisting operation and the pipe auxiliary operation until all pipes are hoisted into the installation groove; S50: Backfilling of the installation trench.
