Description

Technical Field

[0001] This utility model belongs to the field of electromechanical installation engineering technology, specifically a pipeline transportation device. Background Technology

[0002] During the construction of electromechanical installation projects, a large amount of pipes are required, and the pipe diameters vary. During construction, pipes need to be prefabricated on the construction site or in a warehouse and then transported to each construction location, which presents transportation difficulties.

[0003] Currently, pipeline transportation is mainly carried out through two methods:

[0004] 1. After the pipelines are prefabricated, they are transported manually. Manual transportation not only increases the labor intensity of workers, but also some pipelines cannot be transported by one person, thus increasing the number of workers and increasing labor costs.

[0005] 2. After the pipes are prefabricated, they are transported by large or small forklifts. Although using mechanical equipment saves labor intensity, forklifts have space limitations in complex construction sites (they cannot pass or turn around easily), and the cost of using large forklifts is not low, which undoubtedly increases the cost.

[0006] Therefore, a pipeline transportation device is proposed to address the above-mentioned problems. Utility Model Content

[0007] To address the problems mentioned in the background section, this utility model provides a pipeline transportation device, which has the advantages of reducing the labor intensity of workers and overcoming the spatial limitations of forklifts.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a pipeline transportation device, including a mobile trolley, the mobile trolley including a frame and wheels correspondingly arranged on the left and right sides of the bottom of the frame; the frame has a crossbeam for connecting the wheels on the left and right sides; the lower part of the crossbeam and the space between the wheels on the left and right sides are connected to form a transportation space for suspending the pipeline to be transported.

[0009] The vehicle is mounted on a frame and above the transport space, and has a lifting device and a suspension device for the transport pipeline.

[0010] The transport device described above includes: four corresponding wheels mounted on the bottom of the frame; wheels on the same side are fixedly connected by frame linkages; each wheel is connected to a crossbeam via a column; and wheels on opposite sides are connected to each other by axles.

[0012] The transport device described above includes a horizontally mounted boom fixed to the mobile trolley, with the boom installed in the same direction as the trolley's front-to-back direction.

[0013] In the transport device described above, a plurality of fixed seats are fixedly connected to the top of the frame along the axial direction of the boom, and the fixed seats are provided with through holes for the boom to pass through. A first bolt is installed on the top of the fixed seat, and the first bolt movably connects the boom and the fixed seat.

[0014] In the transport device described above, handles are connected to both ends of the boom, each handle includes a connecting rod, the connecting rod is connected to the boom by a second bolt, and handles are fixedly connected to both ends of the connecting rod, with protective sleeves fitted onto the handles.

[0015] The transport device described above includes: bidirectional supports provided near both ends of the boom; lifting straps tied to the bidirectional supports; and a hand-operated hoist hanger installed at one end of the boom near the bidirectional supports.

[0016] In the transport device described above, the bidirectional support includes a first square frame sleeved on the boom, a third bolt is provided at the top of the first square frame, the third bolt movably connects the boom and the first square frame, and diagonal bars are welded to both sides of the first square frame, the diagonal bars being connected to the slings.

The threaded sleeve is threadedly connected to the hanging rod.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. The mobile trolley of this utility model has a stable load-bearing base, which can easily shuttle through narrow passages and complex stacking areas, breaking through the spatial constraints of forklifts that are "difficult to turn around and have narrow passages".

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] like Figures 1 to 5As shown, this utility model provides a pipeline transportation device, including a mobile trolley 1. A horizontally arranged boom 2 is fixed on the mobile trolley 1. The boom 2 provides a horizontal support base for the pipeline and is the core of the load. Handles 3 are connected to both ends of the boom 2. The handles 3 facilitate the operator to control the direction and realize the flexible turning of the trolley. Bidirectional supports 4 are set near both ends of the boom 2. The bidirectional supports 4 are symmetrically distributed and provide installation points for the lifting straps 5 to ensure the force balance at both ends of the pipeline. The lifting straps 5 are tied to the bidirectional supports 4. The lifting straps 5 directly contact the pipeline to realize flexible binding and avoid damage to the pipeline surface. A hand-operated hoist hanger 6 is installed at one end of the boom 2 near the bidirectional support 4. The hand-operated hoist hanger 6 is used to suspend the hand-operated hoist and work with the lifting straps 5 to complete the pipeline leveling operation.

[0035] Specifically, the mobile trolley 1 includes a frame 101, which adopts a frame structure, taking into account both lightweight and structural strength, and provides a stable load-bearing foundation for the entire device. Four corresponding wheels 102 are installed at the bottom of the frame 101. The wheels 102 adopt a multi-wheel layout and are designed for flexible steering, which can adapt to the narrow passages and turning requirements of complex construction sites, thus overcoming the space limitations of forklifts.

[0036] The wheels on both sides are fixedly connected by the frame. Wheels on the same side are fixedly connected by frame linkages. Each wheel is connected to a crossbeam of the frame via a column, with the crossbeam positioned higher than the wheel, thus forming a unified structure between the wheels and the frame. A passageway runs beneath the crossbeam and between the wheels on both sides, creating a transport space for suspending the pipes to be transported. Wheels on opposite sides are not connected by axles, as this would interfere with or disrupt the transport space. The frame, positioned above the transport space, features lifting and suspending devices for the pipes to be transported.

[0037] The distance between the left and right wheels should be greater than the diameter of the pipe to be transported, preferably 10-20cm larger than the pipe's diameter, to facilitate the hanging and unloading of the pipe.

[0038] The suspension device is one or a combination of sling 5 and hand-operated hoist frame 6.

[0039] Furthermore, multiple fixing seats 7 are fixedly connected to the top of the frame 101 along the axial direction of the boom 2. The multiple sets of fixing seats 7 are distributed along the axial direction of the boom 2 to form multi-point support, preventing the boom 2 from bending and deforming due to the weight of the pipe. The fixing seat 7 is provided with a through hole 8 for the boom 2 to pass through. The through hole 8 enables the boom 2 to be quickly inserted and installed, which is convenient for later disassembly and maintenance. The top of the fixing seat 7 is equipped with a first bolt 9. The first bolt 9 can lock the relative position of the boom 2 and the fixing seat 7 to ensure that the boom 2 does not shift during transportation. The first bolt 9 movably connects the boom 2 and the fixing seat 7.

[0040] Furthermore, the handle 3 includes a connecting rod 301, which serves as a bridge connecting the handle 3 and the boom 2. A rigid connection is achieved through the second bolt 302 to ensure the stability of steering control. The connecting rod 301 is connected to the boom 2 through the second bolt 302. Handle handles 303 are fixedly connected to both ends of the connecting rod 301. The handle handles 303 provide gripping points for the operator. A protective cover 304 is fitted on the handle handles 303. The protective cover 304 is made of non-slip and cushioning material to reduce hand fatigue during long-term operation and improve grip comfort.

[0041] It is worth noting that the bidirectional support 4 includes a first square frame 401 sleeved on the hanger 2. The first square frame 401 is installed on the hanger 2 by means of a clamp, which facilitates the adjustment of its position according to the length of the pipeline. A third bolt 402 is provided on the top of the first square frame 401. The third bolt 402 can lock the relative position of the first square frame 401 and the hanger 2, ensuring the stability of the bidirectional support 4 during transportation. The third bolt 402 movably connects the hanger 2 and the first square frame 401. Diagonal bars 403 are welded on both sides of the first square frame 401. The diagonal bars 403 are symmetrically inclined to form a triangular support structure, which improves the load-bearing capacity of the bidirectional support 4 and provides a binding fulcrum for the sling 5. The diagonal bars 403 are connected to the sling 5.

[0042] It is worth noting that the hand chain hoist hanger 6 includes a second square frame 601 sleeved on the rod 2. The second square frame 601 is installed with a clamp, which can flexibly adjust the position of the hanger on the rod 2 to adapt to the leveling requirements of pipes with different diameters. A fourth bolt 602 is provided on the side of the second square frame 601. The fourth bolt 602 locks the second square frame 601 and the rod 2 to prevent the hanger from sliding during the leveling process. The fourth bolt 602 movably connects the rod 2 and the second square frame 601. A vertical rod 603 is fixedly connected to the top of the second square frame 601. The vertical rod 603 provides vertical support for the hanging rod 604 and ensures the installation height of the hanging rod 604. A hanging rod 604 for suspending the hand chain hoist is fixedly connected between the vertical rods 603 near the top. The hanging rod 604 provides the suspension point for the hand chain hoist and is the core force-bearing component for the leveling operation.

[0043] It is worth noting that two limiting rings 10 are fitted on the hanging rod 604. The limiting rings 10 can limit the sliding range of the hand chain hoist on the hanging rod 604 and prevent the hand chain hoist from shifting during the leveling process. A threaded sleeve 11 is fixedly connected to the side of the limiting rings 10 that are far apart. The threaded sleeve 11 is connected to the hanging rod 604 by threads and can quickly lock the position of the limiting rings 10 to adapt to the width requirements of hand chain hoists of different specifications. The threaded sleeve 11 is threadedly connected to the hanging rod 604.

[0044] Working principle and process: First, insert the lifting rod 2 through the through hole 8 on the fixed seat 7 and lock it with the first bolt 9, so that the lifting rod 2 and the frame 101 of the moving trolley 1 form a stable load-bearing structure. Then, put the first square frame 401 of the bidirectional support 4 onto the corresponding position of the lifting rod 2 and fix it with the third bolt 402. Tie the lifting strap 5 to the diagonal rod 403. At the same time, put the second square frame 601 of the hand chain hoist frame 6 onto the lifting rod 2 and lock it with the fourth bolt 602. Adjust the position of the limiting ring 10 on the top hanging rod 604 of the vertical rod 603 and lock it with the threaded sleeve 11. Provide a limit suspension point for the chain hoist, and then connect the connecting rod 301 of the handle 3 to both ends of the boom 2 via the second bolt 302. Use the protective sleeve 304 outside the handle 303 to improve grip comfort. After the device is assembled and debugged, push the handle 3 to make the wheel 102 drive the trolley 1 to the pipeline. The pipeline to be transported is in the gap between the wheels on the left and right sides under the trolley, i.e., within the transport space; and the front end of the pipeline extends beyond the front end of the trolley and is at least below the sling 5, and the front end of the pipeline extends beyond the rear end of the trolley and is below the chain hoist. First, tie the sling 5 on both sides of the bidirectional support 4 to one end of the pipeline. Retract the sling 5 on the end without the chain hoist to raise one end of the pipeline. Then, suspend the chain hoist on the boom 604, and connect the other end of the pipeline to the hook of the chain hoist through the sling. Operate the chain hoist to retract and adjust the pipeline to a horizontal state. Finally, push the handle 303, and rely on the flexible movement of the wheel 102 to transfer the pipeline to the target construction position.
