The working process of the invention is as follows: in an initial state, the holding plate A15 and the holding plate B19 are symmetrically distributed on the arc-shaped inner wall of the portal B8 from left to right; the two clamping blocks A13 are respectively in contact fit with the clamping block D21 on the same side to limit the holding plate B19 from sliding down along the inner wall of the portal B8; the two fixture blocks E51 are respectively in contact fit with the fixture block C18 on the same side; the door frame B8 is positioned at the lowest end of the trapezoidal guide groove A4; the lower end of the holding plate A15 and the lower end of the holding plate B19 are both slightly higher than the ground.

When the large-sized thick circular tube 1 needs to be temporarily transported by the invention, two inventions are needed to be matched with two ends of the thick circular tube 1, and the two inventions lift and transport one thick circular tube 1 together; since the two working principles of the invention for covering and lifting the two ends of the large round pipe 1 are completely the same, only one working principle of the invention is explained as follows:

the method is characterized in that the method is nested on the thick circular pipe 1 from one end of the thick circular pipe 1 along the central axis direction of the thick circular pipe 1, because the lower end of the door frame B8 is opened and the opening size is large, one end of the thick circular pipe 1, the central axis of which is slightly lower than the central axes of the holding plate A15 and the holding plate B19, can enter between the holding plate A15 and the holding plate B19 and pass between the holding plate A15 and the holding plate B19, and gaps exist between the tail end of the holding plate A15 and the tail end of the holding plate B19 and the thick circular pipe 1; then the crank handle 38 is shaken, and the crank handle 38 drives the rotating shaft A25 to rotate; because the pressure of the gravity of the thick circular tube 1 on the door frame B8 is far greater than the resistance of the thick circular tube 1 on the sliding of the holding plate A15 relative to the door frame B8, the gear barrel 33 is relatively fixed and in a stationary state at the moment, the rotating shaft A25 drives the plurality of gears B31 to rotate through the gears A26, the plurality of gears B31 drive the two disks A29 to rotate under the action of the stationary gear barrel 33, and the rotating direction of the disks A29 is the same as that of the rotating shaft A25; the disc A29 connected with the shaft sleeve A27 drives the shaft sleeve A27 to synchronously rotate, and the disc A29 connected with the shaft sleeve B28 drives the shaft sleeve B28 to synchronously rotate; the shaft sleeve B28 drives the chain wheel A32 to synchronously rotate; the chain wheel A32 drives the chain wheel B40 to rotate through a chain A39, the chain wheel B40 drives the worm A41 to synchronously rotate, the worm A41 drives the rotating shaft B43 to rotate through a worm wheel A42 meshed with the worm A3538, and the rotating shaft B43 drives the gear C44 to synchronously rotate; the gear C44 drives the holding plate A15 engaged with the gear C to slide along the arc-shaped inner wall of the door frame B8 and cover the thick circular tube 1 between the holding plate A15 and the holding plate B19; while the two cartridges C18 are respectively moved away from the cartridge E51 on the same side, the two cartridges C18 are respectively moved closer to the cartridge B14 on the same side.

When the tail end of the holding plate A15 reaches the ground, the movement of the holding plate A15 is temporarily stopped due to the stopping of the ground; the rotation of the gear C44 is stopped, the rotating shaft B43 and the worm wheel A42 are stopped, and the worm A41 is stopped; the shaft sleeve D36 in transmission connection with the worm A41 stops rotating, and the two discs A29 stop rotating; the crank 38 is continuously shaken, the crank 38 continuously drives the rotating shaft A25 to rotate, the rotating shaft A25 continuously drives the gears to rotate, and at the moment, the two disks A29 stop rotating, the cylindrical pins 30 where the gears are located simultaneously stop moving around the circumference of the rotating shaft A25, so the gears B31 which continuously rotate drive the gear barrel 33 to rotate, and the rotating direction of the gear barrel 33 is opposite to that of the rotating shaft A25; the gear barrel 33 drives the shaft sleeve C35 and the shaft sleeve D36 to synchronously rotate through two discs B34 respectively; the shaft sleeve D36 drives the chain wheel C37 to rotate, the chain wheel C37 drives the chain wheel D46 to rotate through the chain B45, the chain wheel D46 drives the worm B47 to synchronously rotate, the worm B47 drives the rotating shaft C49 to rotate through the worm wheel B48 meshed with the worm B47, and the rotating shaft C49 drives the gear D50 to synchronously rotate. The rotating gear D50 drives the portal B8 to vertically move upwards through interaction with the upper tooth surface of the portal A3, the portal B8 drives all parts mounted on the portal B8 to synchronously vertically move upwards, and the holding plate A15 and the holding plate B19 lift the thick circular tube 1 positioned between the holding plate A15 and the holding plate B19; when the tail ends of the holding plate A15 and the holding plate B19 synchronously ascend with the portal B8 and are separated from the ground, the prevention of the sliding of the ground surface to the holding plate A15 along the arc-shaped inner wall of the portal B8 is temporarily released; under the condition of continuously shaking the crank 38, the vertical upward movement of the gantry B8 is stopped, so that the rotation of the gear barrel 33 is stopped, the plurality of gears B31 which are continuously driven to rotate by the gear a26 drive the two disks a29 to rotate, the disks a29 drive the shaft sleeve a27 and the shaft sleeve B28 to synchronously rotate, the shaft sleeve B28 drive the chain wheel a32 to rotate, the chain wheel a32 drive the chain wheel B40 to rotate through the chain a39, the chain wheel B40 drive the gear C44 to rotate again through the worm a41, the worm wheel a42 and the rotating shaft B43, and the gear C44 drive the holding plate a15 to slide along the arc-shaped inner wall of the gantry B8 again and further coat the thick circular tube 1; when the tail end of the holding plate A15 touches the ground again, the holding plate A15 stops moving again, the two discs A29 stop rotating again, the gear barrel 33 rotates again, and the gear barrel 33 drives the gantry B8 and all components mounted on the gantry to synchronously move vertically upwards again through a series of transmission; the lifting of the thick round tube 1 is again effected by the embracing plate a15 and the embracing plate B19. Before the outward convex cambered surface of the holding plate A15 is completely tangent to the ground, the crank 38 is continuously shaken to drive the rotating shaft A25 to continuously rotate, the continuously rotating shaft A25 drives the holding plate A15 to coat the thick circular tube 1 through a series of transmissions, and meanwhile, the rotating shaft A25 drives the door frame B8 and all components mounted on the door frame B8 to synchronously vertically move upwards through a series of transmissions; when the holding plate A15 wraps the thick circular tube 1, the holding plate A15 and the holding plate B19 lift the thick circular tube 1 between the holding plate A15 and the holding plate B19, and wrapping and lifting are performed simultaneously. Moreover, from the contact between the tail end of the holding plate A15 and the ground, due to the friction between the holding plate A15 and the thick circular tube 1, the holding plate A15 continuously wraps the thick circular tube 1 to enable the thick circular tube 1 to rotate, the rotating thick circular tube 1 simultaneously drives the holding plate B19 in friction fit with the rotating thick circular tube to slide upwards along the arc-shaped inner wall of the gantry B8, the fixture block A13 is separated from the fixture block D21, and the fixture block C18 gradually approaches to the fixture block B14.

When the convex cambered surface of the holding plate A15 is tangent to the ground, the vertical upward movement of the door frame B8 is stopped, and the rotating shaft A25 driven by hand continuously rotates; the rotating shaft A25 drives the holding plate A15 to continuously wrap the thick circular tube 1 through a series of transmission, the thick circular tube 1 continuously rotates under the action of the holding plate A15, and the thick circular tube 1 continuously drives the holding plate B19 in friction fit with the thick circular tube to slide along the arc-shaped inner wall of the door frame B8; when the clamping block C18 meets the clamping block B14, the holding plate A15 stops moving under the prevention of the clamping block B14, at the moment, the center of the convex arc surface of the holding plate A15 is located at the lowest end of the circle where the convex arc surface of the holding plate A15 is located, two ends of the holding plate A15 are stressed uniformly and stably support the thick circular tube 1, the holding plate A15 and the holding plate B19 well cover the thick circular tube 1, the thick circular tube 1 is completely supported by the holding plate A15, and the holding plate A15 bears all gravity of the thick circular tube 1.

The crank 38 is continuously shaken, the crank 38 drives the rotating shaft A25 to continuously rotate, the rotating shaft A25 drives the gear barrel 33 to rotate through a series of transmission, the gear barrel 33 rotates again through a series of transmission gears D50, the gear D50 drives the door frame B8 and all components mounted on the door frame B8 to synchronously and vertically move upwards through interaction with the tooth surface on the inner wall of the door frame A3, the holding plate A15 drives the thick circular tube 1 supported and coated by the holding plate to vertically move upwards, and the thick circular tube 1 is lifted again. When the thick circular tube 1 is lifted to a certain height from the ground, the crank 38 stops being shaken, the rotating shaft A25 stops rotating, and the gantry B8 stops relative to the gantry A3; because the matching combination of the worm B47 and the worm wheel B48 has a self-locking function, after the acting force on the rotating shaft A25 is removed, the vertical downward reset motion of the door frame B8 cannot occur. Then, two persons in front and at the back push two inventions matched with two ends of the thick circular tube 1 to move to a target position at the same time, after the two inventions reach the target position, the crank 38 is shaken reversely, because the pressure caused by the gravity of the thick circular tube 1 to the portal frame B8 is far greater than the sliding resistance of the thick circular tube 1 to the holding plate a15 relative to the portal frame B8, the gear barrel 33 is relatively fixed and in a static state at the moment, the crank 38 drives the holding plate a15 to slide reversely along the arc-shaped inner wall of the portal frame B8 through a series of transmissions and gradually contacts with the support and the coating of the thick circular tube 1, in the process, the moving holding plate a15 drives the thick circular tube 1 to rotate reversely, the reversely rotating thick circular tube 1 drives the holding plate B19 also coating the thick circular tube 1 to slide reversely along the arc-shaped inner wall of the portal frame B8, and the fixture block C18 is separated from the; with the resetting of the holding plate A15 and the holding plate B19 relative to the portal B8, the tail end of the holding plate A15 gradually releases the coating of the thick circular tube 1.

When the holding plate A15 and the holding plate B19 reset relative to the portal B8, the thick circular tube 1 is still symmetrically coated on two sides by the holding plate A15 and the holding plate B19, the two clamping blocks E51 are respectively in contact fit with the corresponding clamping block D21 again, and the holding plate A15 stops moving under the interaction of the clamping block E51 and the clamping block C18; at this time, the crank 38 is continuously and reversely shaken, the rotating shaft A25 driven by the crank 38 to rotate drives the gear barrel 33 to reversely rotate through a series of transmission, and the gear barrel 33 drives the door frame B8 and all components mounted on the door frame B8 to synchronously vertically move downwards through a series of transmission; the thick circular tube 1 falls to the ground along with the resetting of the holding plate A15 and the holding plate B19 relative to the portal A3; when the door frame B8 drives the holding plate A15 and the holding plate B19 to be completely reset, the thick circular tube 1 completely falls on the ground of a target position; then the invention is pushed to separate from the thick circular tube 1 along the central axis direction of the thick circular tube 1, and then the temporary transportation and transfer of the thick circular tube 1 are completed.

In conclusion, the invention has the beneficial effects that: according to the invention, the gear A26, the gear B31 and the gear barrel 33 are in transmission fit to drive the holding plate A15 to completely coat the large thick circular tube 1, and then the door frame B8 is continuously driven to vertically move upwards relative to the door frame A3, two ends of the large thick circular tube 1 are simultaneously lifted to a certain height from the ground, so that the thick circular tube 1 lifted from the ground is transported; in the whole process of coating and lifting the thick circular tube 1, speed reduction and torque increase are respectively arranged between the gear A26 and the disc A29 where the gears B31 are located, between the gear A26 and the gear barrel 33, between the worm A41 and the worm wheel A42, and between the worm B47 and the worm wheel B48, so that the coating constraint of the holding plate A15 on the thick circular tube 1 and the lifting of the thick circular tube 1 by the door frame B8 through the holding plate A15 are both labor-saving through manually driving the rotating shaft A25 through a series of transmission; meanwhile, due to the fact that the worm A41 and the worm wheel A42 are matched and the worm B47 and the worm wheel B48 are matched to have a self-locking function, after the thick circular tube 1 is wrapped and lifted and acting force acting on the crank 38 is removed, the holding plate A15 cannot slide reversely, the door frame B8 cannot fall vertically, and the thick circular tube 1 is guaranteed to be always kept at a constant distance from the ground in the carrying process. The invention only acts on one end of the thick circular tube 1, so the invention has smaller volume, lighter weight, low production cost, convenient operation and free steering; when the use is finished, the storage is convenient, and the occupied space is small when the storage is in storage. In addition, after the holding plate A15 completely covers the thick circular tube 1, the two ends of the holding plate A15 interact with the two arms of the portal B8 at the same time to effectively support the thick circular tube 1, the stress on the two ends of the holding plate A15 is uniform, the holding plate A15 is not easy to deform under the long-time compression of the thick circular tube 1, and the service life of the novel thick circular tube support is prolonged.
