[0002] At present, the transportation and storage of large-diameter cylindrical products require rapid loading and unloading during transportation and regular automatic rolling during storage.

[0003] In the past, the transshipment of such products was achieved by the cooperation of overhead cranes and ordinary clamps. Taking loading as an example, manual operation is required to cooperate with the overhead crane to open the clamp, then lift the product to the clamp position, and finally cooperate with the overhead crane to close and lock the clamp to achieve the transshipment of the product. During the transshipment process, the main disadvantages are as follows: 1) There are many personnel involved in inspection, operation, command, and observation; 2) The clamp and the product are heavy, and there is a certain degree of danger in the process of manual operation of opening and closing the clamp with the cooperation of the overhead crane; 3) The overall process requires many manual operation steps and is time-consuming.

[0066] The components are as follows:

[0067] like Figure 6 , Figure 7 and Figure 8 As shown, the tumbling device 3 includes two groups of tumbling components and a first power component. The tumbling components include a mounting frame 32, two parallel friction rollers 31, and three first transition shafts 39; the first power component includes a first motor 33, a bevel gear commutator 34, two adapter shafts 35, two first reducers 36, two first gears 37 and eight second gears 38; the eight second gears 38 correspond one-to-one to the four friction rollers 31 and the four first transition shafts 39 in the two groups of tumbling components, and the adapter shafts 35, the first reducers 36 and the first gears 37 correspond one-to-one.

[0070] like Fig. 9 As shown, the automatic docking plug device 2 includes a second motor 22 , a linear module 23 and a docking plug 21 , and the docking plug 21 is adapted to the socket 45 .

[0071] The connections of the components are as follows:

[0072] like Figure 2-Figure 5 As shown, the specific connection method of the clamp device 4 is as follows:

[0073] The lower hoop 41 is a semicircular arc structure, the right hoop 43 and the left hoop 44 are both 1 / 4 arc structures, the lower hoop 41, the right hoop 43 and the left hoop 44 can form an annular cylinder, the inner surface of the annular cylinder is used to contact the cylinder, and the annular cylinder can be tightened within a certain range to meet the tolerance variation of the outer diameter of the cylinder; the definition of an annular cylinder refers to a structure formed by opening a through hole that passes through the solid cylinder along its axis, and the shape of the through hole is not limited, and can be a square, circular or other structure;

[0074] The left and right ends of the lower clamp 41 are hinged to one end of the right clamp 43 and the left clamp 44 respectively. It is defined that the hinge axis between the lower clamp 41 and the left clamp 44 is the first hinge axis, and the hinge axis between the lower clamp 41 and the right clamp 43 is the second hinge axis. The end face of the other end of the left clamp 44 is inclined, and the inclined surface is upward. The other end face of the right clamp 43 is inclined, and the inclined surface is downward. The inclined surface of the right clamp 43 cooperates with the inclined surface of the right clamp 43. A socket 45 is installed on one end face of the lower clamp 41. In order to prevent the socket 45 from interfering with the cylindrical structure, a third cavity is opened on the lower clamp 41, and the socket 45 is installed in the third cavity.

[0075] A first cavity is provided at both left and right ends of the lower clamp 41, and the fourth motor 421 is installed in the first cavity. The axis of the output shaft of the fourth motor 421 is parallel to the axis of the first hinge shaft, and the output end of the fourth motor 421 is connected to the input end of the second reducer 422. The output end of the second reducer 422 is installed with a third gear 423, and the third gear 423 is meshed with one of the second transition gears 425. The fourth gear 424 is installed on the first hinge shaft / second hinge shaft, and the other second transition gear 425 is meshed with the fourth gear 424. The two second transition gears 425 are both installed in the first cavity.

[0076] A second cavity is provided inside the end of the left hoop 44 away from the lower hoop 41, and a clamping frame 6 is provided on the outside of the end of the left hoop 44 away from the lower hoop 41 along its circumference. The thickness of the end of the right hoop 43 away from the lower hoop 41 is adapted to the internal thickness of the clamping frame 6, and a groove running through the top and the end is provided at the upper end of the right hoop 43 placed in the clamping frame 6; the third motor 51 is installed in the second cavity of the left hoop 44, and the axis of the output shaft of the third motor 51 is parallel to the axis of the output shaft of the fourth motor 421. A fifth gear 52 is installed at the output end of the third motor 51, and the fifth gear 52 is meshed with one of the third transition gears 57. The sixth gear 53 is installed at the power input end of the screw lift 54, and another third transition gear 57 is meshed with the sixth gear 53. The two third transition gears 57 are all installed in the second cavity. After the screw of the screw lift 54 ​​passes through the second cavity, it is placed in the clamping frame 6, and the upper end of the screw is hinged to one end of the first connecting rod 55, the other end of the first connecting rod 55 is hinged to one end of the second connecting rod 56, and the other end of the second connecting rod 56 is hinged to the inner wall of the clamping frame 6. The hinge axis between the other end of the first connecting rod 55 and one end of the second connecting rod 56 is defined as the third hinge axis, and the hinge axis between the other end of the second connecting rod 56 and the inner wall of the clamping frame 6 is defined as the fourth hinge axis. Then the third hinge axis and the fourth hinge axis are distributed on both sides of the screw telescopic path, and the fourth hinge axis is located on the left side of the screw; the third hinge axis is used to press into the groove when locking to clamp the right clamp 43. When the screw is at the highest point, the third hinge axis will not interfere with the movement of the right clamp 43.

[0077] The opening and closing principle of the annular cylinder is as follows:

[0078] The fourth motor 421 is used as a power source, and the power is transmitted to the first articulated shaft / the second articulated shaft via the third gear 423, the second transition gear 425 and the fourth gear 424. The first articulated shaft / the second articulated shaft is connected to the left clamp 44 and the right clamp 43 via a flat key. The fourth motor 421 drives the left clamp 44 and the right clamp 43 to rotate forward and reverse, thereby realizing the opening and closing action of the annular cylinder.

[0079] The working principle of the locking assembly 5 is:

[0080] like Fig.12 and Fig.13 As shown, the power of the third motor 51 is transmitted through the fifth gear 52, the third transition gear 57 and the sixth gear 53 to drive the screw of the screw lift 54 ​​to extend or retract, thereby driving the first connecting rod 55 and the second connecting rod 56 to move, so as to tighten or release the right hoop 43. Specifically: when the screw is retracted, the third hinge shaft is driven to move gradually downward and inward, pressing the right hoop 43 to realize the locking function of the right hoop 43; when the screw is extended, the third hinge shaft is driven to move gradually upward and outward, loosening the right hoop 43, realizing the releasing function of the right hoop 43, and ensuring that the right hoop 43 will not interfere with the locking assembly 5 when opening and closing.

[0081] The specific connection mode of the tumbling device 3 is as follows:

[0082] like Figure 6 , Figure 7 and Figure 8 As shown, two fixed bases 9 are arranged on the mounting base 1;

[0083] like Fig.10 As shown, the mounting frame 32 includes two mounting plates and an arc plate connecting the two mounting plates, two friction rollers 31 are installed in parallel between the two mounting plates, and the axis of the friction roller 31 is parallel to the axis of the annular cylinder, the two friction rollers 31 are respectively located at both ends of the mounting plates, and the arc plates of the two mounting frames 32 are respectively installed on two fixed bases 9.

[0084] Or, if Figure 8 As shown, the mounting frame 32 includes two mounting plates and an arc plate connecting the two mounting plates, two friction rollers 31 and three first transition shafts 39 are installed in parallel between the two mounting plates, and the axis of the friction roller 31 is parallel to the axis of the annular cylinder, the two friction rollers 31 are respectively located at both ends of the mounting frame 32, the three first transition shafts are located between the two friction rollers 31 and are arranged in sequence, and the arc plates of the two mounting frames 32 are respectively installed on two fixed bases 9.

[0085] by Figure 8 Taking the example, the specific structure of the tumbling device 3 is introduced. Two friction rollers 31 and one end of the three first transition shafts 39 pass through the same mounting plate. The two friction rollers 31 on both sides and the two first transition shafts 39 are coaxially mounted with second gears 38. The first gear 37 is coaxially mounted on the first transition shaft 39 in the middle. The first gear 37 and the second gear 38, and the second gear 38 and the second gear 38 are meshed with each other. The first gear 37 is coaxially connected to the output end of the first reducer 36, the input end of the first reducer 36 is coaxially connected to one end of the adapter shaft 35, and the other ends of the two adapter shafts 35 are coaxially connected to the two power output ends of the bevel gear commutator 34 respectively, the input end of the bevel gear commutator 34 is coaxially connected to the output end of the first motor 33, the first motor 33, the bevel gear commutator 34 and the first reducer 36 are all mounted on the mounting base 1, and the four friction rollers 31 on the two mounting frames 32 are in friction contact with the annular cylinder.

[0086] The working principle of the tumbling device 3 is as follows:

[0087] The first motor 33 is started, and the power of the first motor 33 is transmitted to the second gear 38 through the bevel gear commutator 34, the adapter shaft 35, the first reducer 36 and the first gear 37. The friction roller 31 is driven to rotate by the second gear 38, and the friction force of the friction roller 31 is used to drive the annular cylinder to rotate.

[0088] The advantages of using the bevel gear commutator 34 and the adapter shaft 35 are that the power of the single first motor 33 can be synchronously transferred to the two first reducers 36, thereby ensuring the synchronous rotation of the first gears 37 on the two first reducers 36;

[0089] The friction roller 31 supports the annular cylinder and drives the annular cylinder to roll through friction. The setting of the second gear 38 ensures that the driving force of the first motor 33 can be synchronously transmitted to the two friction rollers 31.

[0090] like Figure 6 and Figure 8 As shown, in order to ensure the stability of the rotation of the annular cylinder, the two friction rollers 31 and the three first transition shafts 39 are all located in a columnar body formed by the connecting line of the two mounting plates. The distance between the two mounting plates is the same as the thickness of the annular cylinder, that is, a clamping groove is formed between the two mounting plates and the two friction rollers 31, so that the annular cylinder is clamped inside, so that when rotating, the annular cylinder will not shift along the axial direction of the friction roller 31.

[0091] like Fig.10As shown, in order to further ensure the stability of the rotation of the annular cylinder and prevent the annular cylinder from axially moving during rotation, a group of limit members are arranged on the periphery of each mounting frame 32, and the limit member group includes two limit members respectively arranged on both sides along the axial direction of the annular cylinder, and the limit members include a support seat 10, a screw rod 11, a horizontal roller 12 and a slider; the support seat 10 is installed on the mounting base 1, and a slide groove is arranged on the side of the support seat 10 close to the friction roller 31, and the slider is slidably connected in the slide groove, and the horizontal roller 12 is installed on the slider, and one end of the screw rod 11 passes through the support seat 10 and is rotatably connected to the slider, and the screw rod 11 is threadedly connected to the support seat 10, and the axis of the screw rod 11 is parallel to the axis of the annular cylinder, and the horizontal rollers 12 in the two limit members are relatively arranged. Before the annular cylinder rotates, the screw rod 11 is first controlled to rotate so that the slider slides in the slide groove, thereby changing the distance between the two horizontal rollers 12, thereby completing the axial limitation of the annular cylinder.

[0092] like Figure 6 As shown, in order to ensure safety, a cover plate is installed on the mounting plate close to the second gear 38, and the second gear 38 is completely covered by the cover plate. A through hole is provided on the cover plate for the output end of the first reducer 36 to pass through.

[0093] In order to realize automatic power-off and power-on of the opening and closing assembly and the locking assembly on the clamp device, the fourth motor 421 and the third motor 51 are both electrically connected to the socket 45 .

[0094] like Figure 2 and Fig. 9 As shown, in order to realize automatic power on and power off of the socket 45, an automatic docking plug device 2 is provided, the second motor 22 is installed on the mounting base 1, and the axis of the output shaft is arranged horizontally, the output end of the second motor 22 is connected to the power input end of the linear module 23, the docking plug 21 is installed on the power output end of the linear module 23, and the socket 45 is located on the movement path of the docking plug 21, and its working principle is that the second motor 22 drives the linear module 23 to run, and then drives the docking plug 21 to do linear reciprocating motion, so as to realize automatic docking or disconnection between the docking plug 21 and the socket 45 on the lower hoop 41, and the docking plug 21 adopts an explosion-proof plug;

[0095] The advantages of using the linear module 23 are: the linear module 23 is a closed structure, has good dustproof performance, is regularly lubricated by a grease nozzle, and is easy to maintain.

[0096] The first motor 33 , the second motor 22 , and the socket 45 are all electrically connected to a control system. The control system controls the operation of the first motor 33 and the second motor 22 , and controls the operation of the third motor 51 and the fourth motor 421 through the socket 45 .

[0097] like Fig.10As shown, in order to prevent the cylinder from shaking during transportation or under the action of irresistible external forces, four fixing devices are arranged on the annular cylinder, and the four fixing devices are evenly distributed on the two end faces of the annular cylinder. Two fixing devices on each end face are distributed on both sides of the annular cylinder, and are respectively used to connect the mounting frame 32 and the annular cylinder to achieve the fixation of the mounting frame 32 and the annular cylinder; the fixing device includes a basket bolt 7 and two fixing columns, one of which is installed on the end face of the annular cylinder, and the other fixing column is installed on the mounting frame 32, and the two ends of the basket bolt 7 are respectively hung on the two fixing columns, and the locking degree of the mounting frame 32 and the annular cylinder can be controlled by controlling the length of the basket bolt 7.

[0098] like Fig.11 As shown, the outer wall of the cylinder may be deformed during production and transportation. In order to adapt to the size difference caused by this deformation and offset the circular runout error after the left clamp 44 and the right clamp 43 are closed, the connection mode between the mounting frame 32 and the fixed base 9 is set to be hinged, so that the mounting frame 32 can swing within a certain angle range. While improving the supporting stability of the friction roller 31 on the annular cylinder, the circular runout error after the left clamp 44 and the right clamp 43 are closed can be offset, and a limit assembly is added. The limit assembly includes two limit columns 8, which are respectively located on both sides of the radial direction of the hinge axis of the mounting frame 32 and the fixed base 9, one for limiting the downward rotation angle of the mounting frame 32, and the other for limiting the rotation angle of the mounting frame 32 away from the cylinder; if the mounting frame 32 is a hollow structure, the limit column 8 can be equivalently replaced by a limit rod.

[0099] In order to quickly adjust the orientation of the clamp device 4 and speed up the power-on efficiency of the clamp device 4, a position interface is set on the lower clamp 41, and a sensor for identifying the position interface is set on the mounting base 1. When rolling or long-term storage is required, the socket 45 is disengaged from the docking plug 21; when the annular cylinder needs to be opened and closed, the position interface is rolled to the sensor position, and then the socket 45 is docked with the docking plug 21 to automatically open and close the annular cylinder.

[0100] In order to realize manual control or control by other external equipment when the first motor 33, the second motor 22, the third motor 51 and the fourth motor 421 fail or lose power unexpectedly, the first motor 33, the second motor 22, the third motor 51 and the fourth motor 421 are all double-shaft motors. When a failure or a power failure occurs, the motor shaft can be rotated by an external device to realize automatic loading and unloading of the drum and operation of the rolling equipment.

[0101] In order to protect and isolate the cylinder from vibration, felt is arranged on the inner side of the annular cylinder; another advantage of the felt is that it can be compressed within a certain range, so that the annular cylinder can clamp the cylinder with a slight change in outer diameter.

[0102] In order to avoid other components installed on the periphery of the cylinder, a plurality of avoidance gaps are arranged inside the annular cylinder to ensure that there is no interference with the cylinder during normal loading and opening and closing.

[0103] In order to facilitate lifting and assembly, a plurality of lifting rings are provided on the peripheral side of the mounting base 1, and at least one lifting ring is provided at each corner.

[0104] When using the automatic drum loading and unloading and rolling equipment, generally at least two groups are used in coordination, all the equipment is installed on an external mobile device, and the control system controls the operation of all the automatic drum loading and unloading and rolling equipment.

[0105] The advantage of setting the first transition shaft 39, the second transition gear 425 and the third transition gear 57 is that the size of the first gear 37, the second gear 38, the third gear 423, the fourth gear 424, the fifth gear 52, the sixth gear 53, etc. can be reduced, and the rotation speed of the friction roller 31 can be adjusted accordingly.

[0106] The lower clamp 41, the left clamp 44 and the right clamp 43 are made of high-strength aluminum profiles to ensure the load-bearing capacity while reducing the weight of the equipment.

[0107] The lower clamp 41, the left clamp 44 and the right clamp 43 are provided with weight-reducing notches.

[0108] The working principle of the present invention is as follows:

[0109] Install multiple cylinder automatic loading and unloading and rolling devices on the external mobile device in sequence, turn on the second motor 22, and drive the docking plug 21 to move through the linear module 23, so that the docking plug 21 is inserted into the socket 45;

[0110] The third motor 51 is turned on, and the power of the third motor 51 is transmitted to the screw of the screw lift 54 ​​through the fifth gear 52, the third transition gear 57 and the sixth gear 53, so that the screw extends and releases the right hoop 43; the two fourth motors 421 are turned on, and the power of the fourth motor 421 is transmitted to the first hinge shaft and the second hinge shaft through the third gear 423, the second transition gear 425 and the fourth gear 424, and the first hinge shaft and the second hinge shaft drive the left hoop 44 and the right hoop 43 to rotate, so that the left hoop 44 and the right hoop 43 are opened, and then the cylinder to be transported is placed on the lower hoop 41, and the fourth motor 421 is driven to reverse, so that the left hoop 44 and the right hoop 43 are closed, and the third motor 51 is controlled to reverse, and the power of the third motor 51 is transmitted to the screw of the screw lift 54 ​​through the fifth gear 52, the third transition gear 57 and the sixth gear 53, so that the screw retracts, presses the right hoop 43, and completes the fixation of the cylinder to be transported;

[0111] When flipping is required, the first motor 33 is started, and the power of the first motor 33 is transmitted to the second gear 38 through the bevel gear commutator 34, the adapter shaft 35, the first reducer 36 and the first gear 37. The friction roller 31 is driven to rotate by the second gear 38, and the friction force of the friction roller 31 is used to drive the annular cylinder to rotate.

[0116] 2. Check whether the socket 45 is aligned with the docking plug 21. If not, the tumbling device 3 drives the clamp device 4 to roll for alignment;

[0117] 3. The docking plug 21 on the mounting base 1 is translated to complete the power-on of the clamp device 4. At the same time, the locking assembly 5 locks the right clamp 43 to prevent the right clamp 43 from being displaced during the barrel loading process.

[0118] 4. The locking assembly 5 releases the right hoop 43 through the operation of the control system, and the opening and closing mechanism opens the right hoop 43 and the left hoop 44 through the operation of the control system;
