[0002] Conveying equipment is a type of mechanical equipment that continuously transports bulk and packaged goods along a certain route from loading point to unloading point. During pipeline laying, the pipeline is usually placed on the roadside, and then the conveying equipment moves the pipeline from the roadside to the dug pit, where workers then assemble the pipeline.

[0003] Traditional lifting and conveying equipment typically involves directly installing hooks onto pipes, lifting the pipes from the ground, and then moving them into a pit. The traditional lifting and conveying equipment usually has a single, integrated mounting frame, which is inconvenient for transportation and therefore unsuitable for on-site use.

[0013] Compared with the prior art, the beneficial effects of this application are: 1. In this application, by setting a fixed frame, a tripod, a self-locking wheel assembly, a support frame, a fixed block, a lifting body, an insert block, a track device, an S-shaped hook, and a hand chain hoist, the insert block can be inserted into the fixed frame, which facilitates the assembly of the support frame and the lifting body, and facilitates the transportation and on-site assembly of this lifting and conveying equipment. The hand chain hoist can be installed at the bottom of the lifting body through the S-shaped hook, and the pipe can be lifted by the hand chain hoist. The lifting body drives the pipe to move, which facilitates the assembly of the pipe. At the same time, the self-locking wheel assembly rolls in the track device, making the movement of the pipe more stable. 2. In this application, by setting a fixed frame, fixed plate, support wheel, connecting rod, support plate, connecting block, rubber block, locking ball, deformation groove, connecting column, hook ring, rope, guide wheel assembly, connecting disc, turntable, rotating shaft, take-up sleeve, slot, push plate, fixed handle, connecting plate, mounting plate, threaded rod, nut, sliding plate, insert column, and positioning plate, the support wheel installation can be made more stable under the action of the fixed plate. At the same time, the connecting rod makes the entire sliding main structure more stable. The support plate can fix the connecting column. The rubber block set in the connecting block can push the locking ball into the locking groove opened in the support frame, thereby limiting the fixed frame and preventing the fixed frame from moving back and forth during the pipeline assembly process, making the pipeline assembly more stable. The rope can fix the connecting column and take-up sleeve through the hook ring. The connection is achieved by pushing the plate to rotate the take-up sleeve on the outside of the shaft. The take-up sleeve winds up the rope and tensions it, allowing the insert pin to be inserted into the slot of the take-up sleeve through the turntable, thus positioning the take-up sleeve. Then, the nut is threaded onto the outside of the threaded rod to position the mounting plate and prevent it from falling off during use. At the same time, the sliding plate makes the movement of the mounting plate more stable. The fixed handle can drive the turntable, take-up sleeve, and shaft to rotate. At this time, the two take-up sleeves wind up and unwind the two ropes respectively. The rope drives the connecting post, support plate, and fixed frame to move through the hook, making the movement of the fixed frame more stable. At the same time, the tension of the rope makes the rope more sensitive to winding, making it easier to move the connecting post, support plate, and fixed frame through the rope. 3. In this application, the self-locking wheel assembly is supported by the U-shaped track, connecting frame, rotating rod, fixing rod, baffle, first limiting plate, second limiting plate, sliding rod, disc, clamping spring, locking block, mounting block, mounting groove, and limiting groove. This makes the movement of the self-locking wheel assembly more stable. At the same time, the self-locking wheel assembly can stably drive the fixing frame to move. When multiple U-shaped tracks are assembled, the clamping spring can drive the sliding rod, second limiting plate, fixing rod, and baffle to move through the disc. At this time, the baffle is tightly fitted with the mounting block. Meanwhile, the locking block fixedly connected to one side of the baffle is set in the limiting groove opened in the mounting block to prevent the baffle and fixing rod from falling off. This makes the installation between the two U-shaped tracks more stable. At the same time, the U-shaped track installed on one side can be installed on the other side. In this way, an unlimited length of laying can be achieved with a limited number of U-shaped tracks, eliminating the need to lay a large number of U-shaped tracks on the ground and saving laying costs.

The pipe is lifted by the hand-operated hoist 11 and moved by the lifting body 6, which facilitates the assembly of the pipe. At the same time, the self-locking wheel assembly 3 rolls in the track device 8, which makes the movement of the pipe more stable.

[0017] like Figure 1-10As shown, the lifting body 6 includes a sliding body 61, a connecting column 62, a hook ring 63, a rope 64, a guide wheel assembly 65, a storage body 66, a connecting plate 67, a positioning body 68, and a positioning plate 69. A connecting column 62 is installed on the top of the sliding body 61. Hook rings 63 are fixedly connected to the right ends of both the front and rear sides of the connecting column 62. Ropes 64 are installed inside the hook rings 63. A guide wheel assembly 65 is installed on the right side of the front fixing frame 1, and two guide wheel assemblies 65 arranged vertically are installed on the right side of the rear fixing frame 1.

The sliding body 61 includes a fixed frame 611, a fixed plate 612, a support wheel 613, a connecting rod 614, a support plate 615, a connecting block 616, a rubber block 617, and a locking ball 618. Two fixed plates 612 arranged longitudinally and distributed left and right are fixedly connected to the inner side of the fixed frame 611. Support wheels 613 are rotatably connected to the front and rear ends of the left and right sides of the fixed frame 611. One side of the support wheel 613 is connected to the fixed plate 61. 2. Rotary connection: The bottom of the support wheel 613 is tightly fitted with the support frame 4. Two connecting rods 614 are fixedly connected between the two fixed plates 612. The two connecting rods 614 are respectively set on the front and rear sides of the S-shaped hook 10. The horizontal crossbars on the left and right sides of the support frame 4 are cylindrical, and the outer sides of the longitudinal crossbars on the left and right sides of the support frame 4 are provided with evenly distributed slots 9. Support plates 615 are fixedly connected to the left and right sides of the fixed frame 611. The two support plates 615 are respectively fixedly connected to the left and right ends of the bottom of the connecting column 62. A connecting block 616 is fixedly connected to the bottom end of the support plate 615 near the fixed frame 611. The end of the connecting block 616 away from the support plate 615 is arc-shaped, and the arc-shaped side of the connecting block 616 is aligned with one side of the support frame 4. The connecting block 616 has a rubber block 617 inside, and a retaining ball 618 is fixedly connected to one side of the rubber block 617. The side of the retaining ball 618 away from the rubber block 617 is located in the retaining groove 9 opened in the support frame 4. The rubber block 617 has vertically arranged and evenly distributed deformation grooves 619. Through this arrangement, the support wheel 613 can be installed more stably under the action of the fixed plate 612. At the same time, the connecting rod 614 makes the entire sliding body 61 structure more stable. The support plate 615 can fix the connecting column 62. The rubber block 617 inside the connecting block 616 can push the retaining ball 618 into the retaining groove 9 opened in the support frame 4, thereby limiting the fixed frame 611 and preventing the fixed frame 611 from moving back and forth during the pipeline assembly process.To ensure more stable pipe assembly, the main housing 66 includes a connecting plate 661, a turntable 662, a rotating shaft 663, a winding sleeve 664, and a push plate 666. The front of the connecting plate 661 is fixedly connected to the connecting plate 67. The rotating shaft 663 is rotatably connected inside the connecting plate 661. The turntable 662 is fixedly connected to both ends of the rotating shaft 663. A positioning body 68 is installed on one side of the turntable 662. A fixing handle 667 is fixedly connected to the side of the turntable 662 away from the connecting plate 661. One side of the winding sleeve 664 is fixedly connected to the end of the rope 64 away from the hook 63. The push plate 666 is fixedly connected to the outer side of the winding sleeve 664 near the turntable 662. The two winding sleeves 664 are rotatably connected to the outer sides of both ends of the rotating shaft 663. One side of the turntable 664 has evenly distributed slots 665. A positioning body 68 is installed within the slots 665 of the winding sleeve 664. One rope 64 is wound clockwise around the outside of one winding sleeve 664, and another rope 64 is wound counterclockwise around the outside of another winding sleeve 664. The positioning body 68 includes a mounting plate 681, a threaded rod 682, a nut 683, a sliding plate 684, and a post 685. A threaded rod 682, fixedly connected to the turntable 662, passes through the mounting plate 681. A nut 683 is threaded onto the outside of the threaded rod 682. One side of the nut 683 is tightly fitted to the mounting plate 681. Sliding plates 684, fixedly connected to the turntable 662, pass through both the upper and lower sides of the mounting plate 681. The mounting plate 681 is located away from the threaded rod 682. Both ends of one side of the 2 are fixedly connected with inserts 685 that pass through the turntable 662 and are set in the slots 665 of the take-up sleeve 664. The two take-up sleeves 664 are respectively set on the left and right sides of the connecting plate 661, and the two turntables 662 are respectively set on the left and right sides of the connecting plate 67. The fixed handle 667 and the push plate 666 are set in a one-to-one correspondence. Through this setting, the rope 64 can be connected to the connecting post 62 and the take-up sleeve 664 through the hook 63. The push plate 666 drives the take-up sleeve 664 to rotate outside the rotating shaft 663. The take-up sleeve 664 winds up the rope 64 and tensions the rope 64, thereby inserting the inserts 685 through the turntable 662 into the slots 665 of the take-up sleeve 664, thereby tightening the take-up sleeve 664. Positioning is achieved by 64, followed by threading nut 683 onto the outside of threaded rod 682 to position mounting plate 681 and prevent it from falling off during use. Simultaneously, sliding plate 684 ensures more stable movement of mounting plate 681. Fixing handle 667 drives turntable 662, winding sleeve 664, and rotating shaft 663 to rotate. At this time, the two winding sleeves 664 wind and unwind the two ropes 64 respectively. Ropes 64, through hooks 63, drive connecting post 62, support plate 615, and fixing frame 611 to move, making the movement of fixing frame 611 more stable. Furthermore, tensioning ropes 64 makes them more sensitive to winding, facilitating the movement of connecting post 62, support plate 615, and fixing frame 611 via ropes 64.

[0018] like Figure 1 , 11As shown in 12, 13, and 14, the track device 8 includes a U-shaped track 81, a connecting frame 82, a mounting body 83, and mounting blocks 84. The U-shaped track 81 is located below the self-locking wheel assembly 3. Mounting blocks 84 are fixedly connected to the right ends of both the front and rear sides of the U-shaped track 81. Mounting slots 85 are opened on the side of the mounting blocks 84 away from the U-shaped track 81. Connecting frames 82 are fixedly connected to the left ends of both the front and rear sides of the U-shaped track 81. The mounting body 83 is installed inside the connecting frame 82. The end of the mounting body 83 away from the connecting frame 82 is located in the mounting slot 85 opened in the mounting block 84 fixedly connected to the adjacent U-shaped track 81. The mounting body 83 includes a rotating rod 831, a fixing rod 832, a baffle 833, a first limiting plate 834, a second limiting plate 835, and a sliding rod. 836, disc 837, clamping spring 838, and locking block 839; one end of rotating rod 831 is rotatably connected to connecting frame 82; the end of rotating rod 831 away from connecting frame 82 is fixedly connected to a first limiting plate 834; both the upper and lower ends of the first limiting plate 834 are provided with horizontally arranged sliding rods 836; the end of sliding rod 836 away from connecting frame 82 is fixedly connected to a second limiting plate 835; the end of the second limiting plate 835 away from the first limiting plate 834 is fixedly connected to a fixing rod 832; the end of fixing rod 832 away from the second limiting plate 835 is fixedly connected to a baffle 833; both the upper and lower sides of the baffle 833 near the fixing rod 832 are fixedly connected to locking blocks 839; the end of sliding rod 836 away from the second limiting plate 835 is fixedly connected to... A disc 837 is provided, and a clamping spring 838 is provided on the outer side of the end of the slide rod 836 near the disc 837. The end of the clamping spring 838 away from the disc 837 is tightly fitted with the first limiting plate 834. A fixing rod 832, located on one side of the adjacent U-shaped track 81, is installed in the mounting groove 85 opened in the mounting block 84. A baffle 833, located on one side of the adjacent U-shaped track 81, is tightly fitted with the mounting block 84. Two limiting grooves 86 are opened on the left side of the mounting block 84, arranged vertically. A locking block 839, fixedly connected to the right side of the baffle 833 on one side of the mounting block 84, is located in the limiting groove 86 opened in the mounting block 84. Through this arrangement, the self-locking wheel assembly 3 can be supported by the U-shaped track 81, making the movement of the self-locking wheel assembly 3 more stable. The self-locking wheel assembly 3 can stably drive the fixed frame 1 to move. When multiple U-shaped tracks 81 are assembled, the clamping spring 838 can drive the slide rod 836, the second limiting plate 835, the fixing rod 832 and the baffle 833 to move through the disc 837. At this time, the baffle 833 is tightly attached to the mounting block 84. At the same time, the locking block 839 fixedly connected to one side of the baffle 833 is set in the limiting groove 86 opened in the mounting block 84 to prevent the baffle 833 and the fixing rod 832 from falling off, making the installation between the two U-shaped tracks 81 more stable. At the same time, the U-shaped track 81 installed on one side can be installed on the other side. In this way, an infinite length of laying can be achieved with a limited number of U-shaped tracks 81, without the need to lay a large number of U-shaped tracks 81 on the ground, saving laying costs.

[0019] Workflow: When using this pipeline connection lifting and conveying device, firstly, the U-shaped track 81 is laid on the road surface. Then, the baffle 833 is pushed. The baffle 833 moves the second limiting plate 835 through the fixed rod 832. The second limiting plate 835 moves the sliding rod 836 and the disc 837. The disc 837 pushes the clamping spring 838 to be compressed. Then, the fixed rod 832 is moved. The fixed rod 832 moves the second limiting plate 835, the sliding rod 836, and the first limiting plate 834 around the connecting frame 82 in a circular motion. At the same time, the first limiting plate 834 moves the rotating rod 831 within the connecting frame 82 until the fixed rod 832 moves into the mounting slot 85 opened in the mounting block 84. At this time, the baffle 833 is slowly released. The clamping spring 838 moves through the disc 837 and... The sliding rod 836 drives the second limiting plate 835 to move. The second limiting plate 835 drives the baffle 833 to move via the fixing rod 832. The baffle 833 drives the locking block 839 into the limiting groove 86 opened in the mounting block 84, thereby completing the assembly between the two U-shaped tracks 81. At this time, the self-locking wheel assembly 3 can roll in the U-shaped track 81. The self-locking wheel assembly 3 drives the fixing frame 1 and the support frame 4 to move via the tripod 2. The support frame 4 drives the lifting body 6, the S-shaped hook 10 and the hand chain hoist 11 to move. After the bottom hook of the hand chain hoist 11 moves to the appropriate position, the self-locking wheel assembly 3 is locked. Then, the hook of the hand chain hoist 11 is installed on the hook at the top of the pipe. Then, the hand chain hoist 11 is manually pulled. The hand chain hoist 11 drives the pipe upward through the hook. Move the hoist 11 and then lock it. The operator then pushes the fixing handle 667 to rotate, causing the turntable 662 and shaft 663 to rotate. The shaft 663 rotates within the connecting plate 661. Simultaneously, the turntable 662 drives the winding sleeve 664 to rotate via the insert pin 685. The two winding sleeves 664 then drive the two ropes 64, one winding and one unwinding. The two ropes 64 then drive multiple guide wheel assemblies 65 to rotate. The winding rope 64 then drives the connecting pin 62 to move via the hook 63. The connecting pin 62 drives the connecting block 616 and fixing frame 611 to move via the support plate 615. The fixing frame 611 drives the support wheel 613 to roll on the surface of the support frame 4. The support plate 615 drives the locking ball 618 to move. The locking ball 618 moves on the support... Under the action of the arc-shaped groove 9 opened in the support frame 4, the pipe is gradually pushed into the connecting block 616. At this time, the retaining ball 618 pushes the rubber block 617 to deform under the action of the deformation groove 619 until the retaining ball 618 moves into another groove 9 opened in the support frame 4. At the same time, the connecting column 62 drives the pipe to move through the S-shaped hook 10 and the hand chain hoist 11. After the pipe moves to the appropriate position, the pipe is moved into the pit by the hand chain hoist 11 for assembly of the two pipes. During the assembly process, the retaining ball 618 is set in the groove 9 opened in the support frame 4 to limit the connection block 616, the support plate 615 and the fixing frame 611, preventing the fixing frame 611 from moving, and also preventing the S-shaped hook 10 and the hand chain hoist 11 from moving, making the pipe installation more stable.Simultaneously, the connecting post 62 is positioned by the rope 64 to further prevent the S-hook 10 and the hand chain hoist 11 from moving. After assembly, the hook of the hand chain hoist 11 is removed from the pipe. The turntable 662 is rotated in the opposite direction by the fixing handle 667, thereby moving the fixing frame 611. When replacing the rope 64, the nut 683 is rotated, and then the mounting plate 681 is moved. The mounting plate 681 moves outside the slide plate 684, and at the same time, the mounting plate 681 removes the insert post 685 from the slot 665 opened in the take-up sleeve 664. Then, the push plate 666 pushes the take-up sleeve 664 to rotate outside the rotating shaft 663, and the take-up sleeve 664 guides the rope 64. The rope 64 is tensioned during winding, and then the mounting plate 681 is pushed. The mounting plate 681 drives the insert 685 to be inserted into the slot 665 of the winding sleeve 664, thereby positioning the winding sleeve 664. The nut 683 is rotated in the opposite direction, and the mounting plate 681 is positioned by the nut 683 threaded to the outside of the threaded rod 682. By tensioning the rope 64, before the self-locking pulley assembly 3 moves to the end of the rightmost U-shaped track 81, the left-end U-shaped track 81 is disassembled in the reverse manner of the above installation process, and then installed on the right-end U-shaped track 81 to facilitate the cyclic laying of the U-shaped track 81.
