Thus, a feature defined as "first", "second", "third", and "fourth" may explicitly or implicitly include at least one of the features.

[0042] like Figures 1 to 5 , Fig.11 As shown, the present invention provides a duct vertical transportation device, comprising:

[0043] A walking frame 1 is used for walking on the ground, and the walking frame 1 is in a "U" shape;

[0044] The lifting frame 2 is used to place the air duct. The lifting frame 2 includes two side support plates 2.1 and a middle support plate 2.2 connected between the middle parts of the two side support plates 2.1. The outer side surface of the side support plate 2.1 is provided with a strip groove 3 with two ends being semicircular;

[0045] Two slides 4 are slidably arranged on both sides of the traveling frame 1 in the height direction, and rollers 5 adapted to the strip grooves 3 are arranged on the inner side surfaces of the slides 4, and the inner ends of the rollers 5 extend into the strip grooves 3;

[0046] Two lifting seats 6 are slidably arranged on both sides of the traveling frame 1 in the height direction, and the two lifting seats 6 are respectively supported on the bottom of the two sliding seats 4;

[0047] A support arm 7 is rotatably mounted on the inner side of the lifting seat 6, and a through slot 8 is provided at one end of the support arm 7 away from the lifting seat 6. Insertion rods 9 are provided on both the upper and lower sides of the middle support plate 2.2, and the insertion rods 9 located at the lower side are sequentially inserted into the through slots 8 of the two support arms 7;

[0048] The lifting seat 6 is connected to a driving assembly 10 , which is installed on the traveling frame 1 and is used to drive the lifting seat 6 to perform lifting motion.

[0049] In this embodiment, the driving component 10 pushes the lifting seat 6 to move upward, and the lifting seat 6 pushes the slide 4, so that the slide 4 supports the lifting frame 2 to move upward through the roller 5 and the strip groove 3. During this process, the roller 5 is supported at one end of the strip groove 3, and the lifting seat 6 is supported at the middle part of the lower surface of the lifting frame 2 through the support arm 7, so that the lifting frame 2 can stably support the air duct to move upward and transport the air duct vertically to the installation height.

[0050] After the rear end of the first air duct is fixed, the traveling frame 1 is directly pushed forward, so that the roller 5 moves from the rear end to the front end of the strip groove 3. In this process, the support arm 7 is displaced outside the insertion rod 9 through the through groove 8, and the end connected to the lifting seat 6 is rotated from the rear end to the front end of the air duct that has completed the fixing operation. At this time, the front end of the traveling frame 1 is kept in an aligned state with the front end of the air duct that has completed the fixing operation.

[0051] Then, the lifting frame 2 is reset downward to the lowest height through the driving assembly 10, and then the lifting frame 2 is lifted up so that the insertion rod 9 on the lower surface of the lifting frame 2 is simultaneously pulled away from the two supporting plates 15, and then the lifting frame 2 is rotated 180° around the roller 5, so that the front and rear ends of the lifting frame 2 are swapped, and then the lifting frame 2 is lowered so that the insertion rod 9 on the lower surface of the lifting frame 2 is reinserted into the through slots 8 of the two supporting arms 7. At this point, the front and rear swapping of the lifting frame 2 is completed.

[0052] Then place the next air duct to be installed on the lifting frame 2, and restart the driving assembly 10, so that the lifting frame 2 lifts the air duct on its top to the installation height. At this time, the lifted air duct and the previous air duct that has completed the fixing operation are in an aligned state in the front-to-back direction and the height direction, which is more convenient for the alignment and connection of the air duct and improves the efficiency of the air duct installation.

[0053] like Figure 6 and Figure 8 As shown, a front baffle 11 and a rear baffle 12 are provided on the front and rear sides of the middle support plate 2.2. The front baffle 11 located on the front side of the middle support plate 2.2 is located above the rear baffle 12, and the front baffle 11 located on the rear side of the middle support plate 2.2 is located below the rear baffle 12. The front baffle 11 is located on the front side of the air duct being vertically transported on the lifting frame 2, and the rear baffle 12 is located on the rear side of the front edge of the last installed air duct.

[0054] By setting the front baffle 11 and the rear baffle 12 to limit the front and rear sides of the air duct on the lifting frame 2, the stability and safety of the vertical transportation of the air duct are improved. The rear baffle 12 can position the lifting frame 2 in the process of pushing the walking frame 1 to move, and prevent the lifting frame 2 from moving forward by contacting the rear side of the front edge of the air duct that has been fixed.

[0055] The front baffle 11 and the rear baffle 12 are both step-shaped, and the maximum distance between the front baffle 11 and the rear baffle 12 located on the same side of the middle support plate 2.2 in the height direction is greater than the length of the air duct.

[0056] The air duct located on the lifting frame 2 can be appropriately displaced between the front baffle 11 and the rear baffle 12, which is more convenient for placing the sealing gasket when the air duct is connected. A gap needs to be formed between the two air ducts. At the same time, it is also convenient to place the air duct on the lifting frame 2.

[0057] like Figure 7 and Fig. 9 As shown, bearings 13 are provided on the inner side surfaces of the front and rear ends of the side support plate 2.1, the center of the bearing 13 coincides with the center of the end of the strip groove 3, a connecting shaft 14 is inserted into the bearing 13, and a support plate 15 is connected to the connecting shaft 14. The support plate 15 can rotate between the upper and lower side surfaces of the end of the side support plate 2.1, and the side of the support plate 15 close to the side support plate 2.1 is in contact with the surface of the side support plate 2.1.

[0058] The bearing 13 surrounds the connecting shaft 14 to limit the connecting shaft 14. At the same time, the connecting shaft 14 can serve as a rotation fulcrum for the support plate 15, so that the connecting plate can switch positions between the upper and lower sides of the side support plate 2.1. After the lifting frame 2 is swapped front and back, the position of the support plate 15 can be adjusted by rotating the support plate 15 at the end of the side support plate 2.1.

[0059] When the support plate 15 is on the upper and lower sides of the side support plate 2.1, the height of the step surfaces of the front baffle 11 and the rear baffle 12 on the same side as the support plate 15 in the height direction is adapted to the height of the side of the support plate 15 away from the side support plate 2.1.

[0060] When the air duct is placed on the lifting frame 2, the bottoms of the front and rear ends of the air duct are supported by the front baffle 11 and the rear baffle 12 respectively, so as to improve the stability of the air duct.

[0061] like Figures 10 to 12 As shown, the bearing 13 includes a first bearing body 13.1 and a second bearing body 13.2 which are relatively distributed front and back, and a notch 13.3 is provided between the two opposite ends of the first bearing body 13.1 and the second bearing body 13.2. Both the first bearing body 13.1 and the second bearing body 13.2 are connected with a tension spring 16, and one end of the tension spring 16 is connected to the side support plate 2.1.

[0062] The first bearing body 13.1 and the second bearing body 13.2 move in opposite directions, so that the notch 13.3 becomes larger and larger, so that the connecting shaft 14 can enter or leave the bearing shell 13. At the same time, the notch 13.3 is set so that when the connecting shaft 14 keeps the same position in the height direction, when the bearing shell 13 moves downward or upward as a whole following the lifting frame 2, the connecting shaft 14 squeezes the notch 13.3 to make the first bearing body 13.1 and the second bearing body 13.2 move in opposite directions, and the tension spring 16 is stretched, so that the connecting shaft 14 can automatically enter or leave the bearing shell 13 by utilizing the relative movement of the connecting shaft 14 and the bearing shell 13 in the height direction.

[0063] like Figure 5 and Figure 7 As shown, grooves 17 are provided on both sides of the top of the walking frame 1, and isosceles trapezoidal limit grooves 18 are provided on the upper and lower inner wall surfaces of the groove 17. Isosceles trapezoidal limit blocks 19 are provided in the limit grooves 18, and an external top spring 20 is provided between the two limit blocks 19. The two limit blocks 19 are both slidably installed on the outer side surface of the support plate 15 in the height direction, and the front and rear side surfaces of the groove 17 are provided with openings 21 for the two limit blocks 19 to enter or leave the groove 17 in a compressed state.

[0064] When the walking frame 1 moves forward to the front end of the lifting frame 2 relative to the lifting frame 2, the front end opening 21 of the groove 17 is put on the rear end bevel of the limit block 19, so that the two limit blocks 19 move relative to each other and compress the outer top spring 20. The two limit blocks 19 can pass through the opening 21 and enter the limit groove 18. When the limit blocks 19 enter the limit groove 18, the limit blocks 19 automatically move back and forth under the left and right sides of the outer top spring 20, so that under the elastic action of the outer top spring 20, the limit blocks 19 cooperate with the limit groove 18 to limit the support plate 15, so that the support plate 15 is effectively positioned on the walking frame 1.

[0065] Similarly, when the support plate 15 is positioned on the walking frame 1, when the walking frame 1 moves forward, the limit block 19 will be squeezed through the limit groove 18 to compress the outer top spring 20, so that the two limit blocks 19 leave the groove 17 through the opening 21, thereby realizing the separation of the support plate 15 and the walking frame 1.

[0066] like Figures 9 to 13 As shown, the first slider 22 is fixedly provided on the outer side of the first tile body 13.1 and the second tile body 13.2, the first slide groove 23 is provided on the inner surface of the side support plate 2.1, the first slider 22 is slidably provided in the first slide groove 23, the inner side end of the limit block 19 is fixedly provided with a second slider 24 in a "T" shape, the outer side of the support plate 15 is provided with a second slide groove 25 in a "T" shape, the second slider 24 is slidably provided in the second slide groove 25, and the limit block 19 is located on the outer side of the side support plate 2.1. The cooperation between the second slider 24 and the second slide groove 25 stably installs the support plate 15 on the walking frame 1, and the limit block 19 will not cause any obstruction during the front-to-back swapping of the side support plate 2.1 and the rotation of the support plate 15 at the end of the side support plate 2.1.

[0067] like Figure 1 and Figure 6 As shown, the ends of the two supporting arms 7 connected to the lifting seat 6 are at the same height, and the ends of the two supporting arms 7 sleeved on the insertion rod 9 are in an up-and-down staggered state.

[0068] like Figure 1 and Figure 6 As shown, the driving assembly 10 includes a motor 10.1 and a screw rod 10.2, the screw rod 10.2 is threadedly connected to the lifting seat 6, the screw rod 10.2 is rotatably mounted on the outer side of the traveling frame 1, and the bottom end of the screw rod 10.2 is connected to the power shaft of the motor 10.1, and the power shaft is mounted on the traveling frame 1. When the motor 10.1 is started, the motor 10.1 rotates forward or reversely through the electric screw rod 10.2, and the lifting seat 6 can be driven to rise or fall through the screw rod 10.2. At the same time, by using the threaded cooperation between the screw rod 10.2 and the lifting seat 6, during the process of moving the traveling frame 1, the lifting seat 6 maintains stable support for the lifting frame 2 through the supporting arm 7.

[0069] The method of using the duct vertical transportation equipment provided in this implementation is as follows:

[0070] ① When transporting the air duct vertically, the walking frame 1 is located at the rear end of the lifting frame 2, the roller 5 is located at the rear end of the strip groove 3, the support plate 15 located at the front side is located at the top of the side support plate 2.1, and the support plate 15 located at the rear side is located at the bottom of the side support plate 2.1.

[0071] The air duct is placed on the lifting frame 2. At this time, the bottom sides of the front edge of the air duct are supported by two support plates 15 located at the front side, and the support plates 15 are supported by the side support plates 2.1. The bottom middle of the rear edge of the air duct is supported by the rear baffle plate 12, and the air duct is limited between the front baffle plate 11 and the rear baffle plate 12 in the front and rear directions. The front and rear ends of the air duct are at the same height.

[0072] ② Start the motor 10.1, the motor 10.1 and the electric screw 10.2 rotate, and the screw 10.2 drives the lifting seat 6 to move upward.

[0073] The lifting seat 6 supports the rear end of the lifting frame 2 by means of the upper slide 4 and the roller 5, and the lifting seat 6 supports the middle part of the lifting frame 2 by means of the supporting arm 7, thereby being able to keep the lifting frame 2 stable in a horizontal state and move upward, and transport the air duct vertically to the installation height.

[0074] ③Fix the rear end of the air duct to achieve fixation of the rear end of the air duct.

[0075] ④ Push the walking frame 1 forward, and the walking frame 1 moves forward outside the lifting frame 2. During this process, the roller 5 moves forward in the strip groove 3, and the support arm 7 moves outside the insertion rod 9 through the strip groove 3 and the relative rotation between the support arm 7 and the lifting seat 6, so that the support arm 7 maintains the state of supporting the lifting frame 2 and follows the adjustment state of the walking frame 1.

[0076] During the movement of the traveling frame 1, the driving assembly 10 moves synchronously with the traveling frame 1, thereby ensuring that the height of the lifting frame 2 remains unchanged. When the rear baffle 12 contacts the rear side of the front edge of the air duct that has completed the fixing operation, when it corresponds to the first air duct, the rear baffle 12 contacts the rear side of the rear edge of the first air duct, so that the lifting frame 2 will not move with the traveling frame 1.

[0077] At the same time, the groove 17 separates the pallet 15 on the rear side from the walking frame 1 by squeezing the limit block 19, and when the walking frame 1 moves to the front end of the lifting frame 2, the pallet 15 on the front side is positioned on the walking frame 1. When corresponding to the first air duct, the groove 17 will only perform the process of putting on the upper limit block 19 on the front side pallet 15.

[0078] ⑤ Start the motor 10.1, so that the screw rod 10.2 drives the lifting seat 6 to move downward. At this time, the bearing 13 on the front side squeezes the top of the connecting shaft 14 under the action of the overall gravity of the lifting frame 2, so that the bearing 13 on the front side is automatically opened, the lifting frame 2 automatically moves downward, and the connecting shaft 14 on the front side is disengaged from the bearing 13 on the front side.

[0079] Afterwards, the lifting frame 2 continues to move downward, and the support plate 15 located on the front side is positioned at the top of the walking frame 1 by the groove 17 and the limit groove 18. At this time, the support plate 15 located on the front side remains supported on the front end of the previous air duct. At this time, the front end of the previous air duct has not yet been connected to the next air duct and is in a suspended state, thereby achieving the effect of auxiliary support and positioning of the suspended end of the previous air duct.

[0080] ⑥ After the lifting frame 2 is lowered to the lowest position, the lifting frame 2 is directly pushed upward so that the insertion rod 9 is pulled out of the two supporting arms 7, and then the lifting frame 2 is rotated with the roller 5 in the front end as the fulcrum to achieve the exchange of the front and rear ends of the lifting frame 2.

[0081] ⑦ After the front and rear ends of the lifting frame 2 are swapped, the lifting frame 2 is lowered so that the insertion rod 9 located on the lower surface of the lifting frame 2 is reinserted into the through grooves 8 of the two supporting arms 7.

[0082] ⑧ Place the next air duct on the lifting frame 2 and start the motor 10.1 to lift the air duct to the installation height. During this process, the notch 13.3 at the top of the bearing 13 at the rear end of the lifting frame 2 passes from bottom to top through the bottom of the connecting shaft 14 on the top support plate 15 of the walking frame 1. The bearing 13 automatically opens and re-puts on the connecting shaft 14. After fixing the tail end of the air duct to the front end of the previous air duct, the walking frame 1 can be pushed forward and the front and rear end swapping operation of the lifting frame 2 can be completed again.

[0083] Afterwards, the above-mentioned operation method is followed in a cycle to realize vertical transportation and docking installation of the air ducts one by one.

[0084] The technical scope of the present invention is not limited to the contents of the above description. Those skilled in the art can make various deformations and modifications to the above implementation without departing from the technical idea of ​​the present invention, and these deformations and modifications should all fall within the scope of the present invention.
