For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] Please see Figure 1 This invention provides a material cylinder transfer device for clamping the flange 93 on the top edge of a material cylinder 90. The material cylinder 90 is generally cylindrical, and the flange 93 is disposed at the junction of the cylinder side wall 91 and the top cover 92. The flange 93 protrudes from the cylinder side wall 91 and the top cover 92, and the cross-section of the flange 93 is generally circular.

[0033] The material barrel transfer device includes a support frame 10, a clamping mechanism 20, and a drive mechanism 30.

[0034] The support frame 10 is provided with a movable structure 101 that can move on the ground. The movable structure 101 can be a roller, track, or other movable structural component. The other movable structural component can be independent of the support frame 10 or can be assembled onto the support frame 10.

[0035] Please combine Figure 2 and Figure 3 The clamping mechanism 20 includes a connector 23, a clamping member 21, and a supporting member 22. The connector 23 is movably connected to the support frame 10 and extends in the vertical direction. The clamping member 21 is connected to the connector 23 and can clamp the flange 93. The clamping member 21 can clamp the flange 93 by electric power or by its own mechanical structure. The supporting member 22 is connected to the connector 23 and is located below the clamping member 21. Both the supporting member 22 and the clamping member 21 are located on the front side of the connecting rod 231.

[0036] The driving mechanism 30 is connected to the support frame 10 and is used to drive the upward movement of the connecting piece 23. The driving piece can drive the connecting piece 23 by electric power or by its own mechanical structure, which is not limited here. The upward movement of the connecting piece 23 can be achieved by the sliding connection between the connecting piece 23 and the support frame 10, or by the telescopic deformation of the support frame 10, wherein the support frame 10 can limit the forward and backward movement of the connecting piece 23, that is, the connecting piece 23 can not move in the forward and backward direction, or only move in the forward and backward direction within a certain area.

[0037] Wherein, after the clamping piece 21 clamps the flange 93 and the connecting piece 23 moves upward to make the barrel 90 leave the ground, the abutting piece 22 can abut against the barrel side wall 91 of the barrel 90, so that the included angle between the central axis of the barrel 90 and the normal line of the horizontal plane is less than a preset value.

[0038] In use, first move the barrel transfer device to the rear side of the barrel 90, that is, make the barrel 90 located at the front side of the barrel transfer device, then drive the connecting piece 23 to move upward by the driving mechanism 30, when the clamping piece 21 moves upward to the vicinity of the flange 93 of the barrel 90, it can clamp the flange 93, at this time, the abutting piece 22 can abut against the barrel side wall 91 of the barrel 90, or be spaced from the barrel 90. Then the connecting piece 23 continues to move upward until the barrel 90 leaves the ground. Since the clamping piece 21 clamps a point of the flange 93, the barrel 90 is inclined under the action of gravity, the bottom of the barrel 90 swings toward the direction of the abutting piece 22, and the abutting piece 22 can abut against the barrel side wall 91 of the barrel 90 to limit the continuous swinging of the bottom of the barrel 90 toward the direction of the abutting piece 22. The barrel 90 is tightly attached to the abutting piece 22 by its own gravity, thereby limiting the swinging of the barrel 90 and improving the reliability of the barrel 90 transfer process. At the same time, manual control of the balance of the barrel 90 is not required, saving manpower.

[0039] Optionally, the preset value is less than or equal to 30° and greater than 0°, the smaller the included angle, the greater the pressure of the barrel 90 on the abutting piece 22.

[0040] Please refer to Figure 2 and Figure 3In some embodiments, the clamp 21 comprises a housing 211, a lower clamp tooth 212, an upper clamp tooth 213 and a first connecting rod 214. The housing 211 comprises two opposite side plates 2111 and a back plate 2112 connecting the two side plates 2111, the two side plates 2111 are located at left and right sides, and the upper clamp tooth 213, the lower clamp tooth 212 and the first connecting rod 214 are located between the two side plates 2111. The upper clamp tooth 213 is located above the lower clamp tooth 212, and the upper clamp tooth 213 has an upper tooth portion 2131, an upper connecting portion 2132 and an upper tail portion 2133 connected in sequence, the upper tail portion 2133 is located at the rear side of the upper tooth portion 2131 and is rotatably connected to the side plate 2111 through a first rotating shaft, and the first connecting rod 214 extends substantially in the up-down direction, i.e., the included angle between the first connecting rod 214 and the normal line of the horizontal plane is less than 45°. The upper end of the first connecting rod 214 is rotatably connected to the upper connecting portion 2132 through a second rotating shaft. Since the position of the upper tail portion 2133 of the upper clamp tooth 213 is fixed and can only rotate around the first rotating shaft, the up-down movement of the first connecting rod 214 can make the upper tooth portion 2131 move up and down by pulling the upper connecting portion 2132 of the upper clamp tooth 213. The lower clamp tooth 212 has a lower tooth portion 2121 and a lower tail portion 2122 connected in sequence, the lower tail portion 2122 is located below the lower tooth portion 2121, the lower clamp tooth 212 is movably connected to the side plate 2111 and can move between a first position and a second position, and the movable connection between the lower clamp tooth 212 and the side plate 2111 includes but is not limited to sliding connection, rotating connection, etc. The first position is located above the second position, i.e., the lower clamp tooth 212 can move up and down by sliding between the first position and the second position. The lower clamp tooth 212 can abut below the flange 93 during the movement of the connecting piece 23, and the lower clamp tooth 212 is driven to move from the first position to the second position under the action of the gravity of the barrel 90, the first connecting rod 214 pulls the upper clamp tooth 213 to rotate, so that the upper tooth portion 2131 moves downward to abut above the flange 93, thereby making the upper tooth portion 2131 and the lower tooth portion 2121 clamp the flange 93 together.

[0041] In use, the lower tooth portion 2121 of the lower clamping tooth 212 is first moved below the flange 93, and then the connecting member 23 is driven upward by the driving mechanism 30 until the lower clamping tooth 212 abuts against the flange 93, the connecting rod 231 is continuously driven upward by the driving mechanism 30, and the flange 93 abuts against the lower clamping tooth 212 under the gravity of the barrel 90, so that the position of the lower clamping tooth 212 remains unchanged, the lower clamping tooth 212 is moved from the first position to the second position due to the upward movement of the connecting member 23, i.e. the lower clamping tooth 212 is moved downward relative to the side plate 2111, the upper connecting portion 2132 of the upper clamping tooth 213 is moved downward by pulling the first connecting rod 214, the upper tooth portion 2131 is rotated relative to the upper tail portion 2133 and is moved downward until it hooks the upper side of the flange 93, so that the upper tooth portion 2131 and the lower tooth portion 2121 clamp the flange 93, and the connecting member 23 is continuously moved upward, so that the clamping member 21 can clamp the barrel 90 away from the ground. In this way, the clamping member 21 clamps the flange 93 through its own mechanical structure, without the need for electric power, thereby saving energy. The first connecting rod 214 connected to the upper connecting portion 2132 can increase the displacement of the upper tooth portion 2131.

[0042] Optionally, the upper tooth portion 2131 and the lower tooth portion 2121 are provided with hook-shaped structures to hook the connection between the flange 93 and the main body of the barrel 90. Since the cross section of the flange 93 is circular, the connection is narrower than the diameter of the flange 93, and the upper tooth portion 2131 and the lower tooth portion 2121 hook the narrower part through the hook-shaped structures to limit the flange 93 from being separated from the clamping member 21.

[0043] Please refer to Figure 2 and Figure 3 In some embodiments, the side plate 2111 is provided with a sliding groove 210 extending in the upward and downward directions, and the lower tail portion 2122 of the first connecting rod 214 is slidingly connected to the sliding groove 210 through a sliding block. The sliding groove 210 can achieve the sliding connection between the lower clamping tooth 212 and the side plate 2111. The lower clamping tooth 212 can be translated and slid, or can be rotated while being slid.

[0044] Optionally, the sliding groove 210 extends in an arc-shaped path, and the sliding block is also arc-shaped and matches the sliding groove 210, and the arc protrudes backward. When the sliding block slides relative to the sliding groove 210, the lower tooth portion 2121 can be rotated synchronously during the downward movement, and the lower tail portion 2122 performs a circular motion. Since the lower tooth portion 2121 is close to the center of the circle corresponding to the arc-shaped path, it only rotates in a small range to hook the connection between the flange 93 and the main body of the barrel 90, thereby improving the hooking stability.

[0045] Optionally, the second position is located in front of the first position, so that the lower clamping tooth 212 can move forward during the downward movement to ensure that the lower tooth part 2121 can reach the connection between the flange 93 and the main body of the barrel 90, avoiding the disengagement of the flange 93 when the lower tooth part 2121 hooks the flange 93.

[0046] Referring to Figure 2 and Figure 3 In some embodiments, the clamping member 21 further comprises a first elastic member connected to the lower clamping tooth 212 and the housing 211 or the upper tail part 2133. The first elastic member can apply an upward elastic force to the lower clamping tooth 212 when the slider moves towards the second position, so that the slider can be reset to the first position after the lower clamping tooth 212 disengages the flange 93. When the lower clamping tooth 212 moves downward under the pressure of the flange 93, the first elastic member is stretched and generates an elastic force to move the lower clamping tooth 212 upward. After the flange 93 is released, the lower clamping tooth 212 can return to the first position from the second position under the action of the elastic force, in preparation for clamping the flange 93 next time. The setting of the first elastic member can realize the automatic reset of the lower clamping tooth 212 and save energy. In other embodiments, the lower clamping tooth 212 can also have a damping force with the side plate 2111, and be reset by manual pushing, and descend when the pressure of the flange 93 is greater than the damping force. The setting of the first elastic member can also play a buffering role for the downward movement of the lower clamping tooth 212, avoiding the sudden downward movement of the lower clamping tooth 212 during the upward movement of the connecting member 23, which can damage the housing 211.

[0047] Optionally, the housing 211 further comprises a limiting rod 2113, both ends of the limiting rod 2113 are connected to the two side plates 2111 respectively, and the limiting rod 2113 is located below the lower clamping tooth 212. When the lower clamping tooth 212 moves to the second position, the lower tail part 2122 abuts against the limiting rod 2113. The limiting rod 2113 is located in front of the slider. The setting of the limiting rod 2113 can avoid the rotation of the lower clamping tooth 212, provide support for the lower clamping tooth 212, and share the stress of the slider.

[0048] Referring to Figure 2 and Figure 3In some embodiments, the clamping member 21 is movably connected to the connecting member 23 and is capable of moving between a starting position and a clamping position, the starting position being above the clamping position. The clamping mechanism 20 further comprises a second elastic member, two ends of the second elastic member being connected to the housing 211 and the connecting member 23, and the second elastic member being capable of exerting an elastic force on the clamping member 21 to move the clamping member 21 towards the starting position when the clamping member 21 moves towards the clamping position. The second elastic member provides a buffer for the clamping member 21, avoiding the lower clamping tooth 212 from moving upwards immediately when the connecting member 23 moves upwards, which causes the upper tooth portion 2131 to not be clamped in place. When the connecting rod 231 moves upwards, the clamping member 21 first moves downwards relative to the connecting rod 231 under the elastic force of the second elastic member, to slow down the speed of the upward movement of the lower clamping tooth 212, thereby ensuring that the upper tooth portion 2131 can stably clamp the flange 93 with the lower tooth portion 2121.

[0049] Optionally, the clamping mechanism 20 further comprises a linkage assembly 24, and the clamping member 21 is movably connected to the connecting member 23 through the linkage assembly 24. The linkage assembly 24 comprises two groups of second connecting rods 241, each second connecting rod 241 having a first end and a second end, each group of second connecting rods 241 comprising two parallel second connecting rods 241, the first ends of the two second connecting rods 241 being rotatably connected to the two side plates 2111 respectively, and the second ends of the two second connecting rods 241 being rotatably connected to the connecting member 23, the two groups of second connecting rods 241 being arranged in the up-down direction, and the clamping member 21 being capable of moving between the starting position and the clamping position through the rotation of the second connecting rods 241. In this way, the two groups of second connecting rods 241, the housing 211 and the connecting member 23 jointly form a quadrilateral structure, which can ensure that the lower clamping tooth 212 stably moves downwards, and at the same time, can move backwards during the downward movement, to reduce the gap between the flange 93 and the abutting member 22 in the front-back direction, thereby reducing the angle between the axis of the barrel 90 and the normal of the horizontal plane when the barrel 90 is clamped, and increasing the pressure exerted by the barrel 90 on the abutting member 22, thereby improving the stability of the clamping of the barrel 90. The lengths of the two second connecting rods 241 in each group of second connecting rods 241 are equal, to avoid the clamping member 21 from being skewed.

[0050] Optionally, the two groups of second connecting rods 241 are parallel, and the length of the second connecting rods 241 on the upper side is less than that of the second connecting rods 241 on the lower side. In this way, the clamping member 21 can rotate while moving downward and backward, i.e., the circumferential movement distance of the lower tail part 2122 is greater than that of the lower tooth part 2121. When the angle between the central axis of the barrel 90 and the horizontal plane normal line decreases due to the abutting of the abutting member 22 and the downward movement of the clamping member 21, the connection between the flange 93 and the main body of the barrel 90 moves upward, and through the arrangement of the connecting rod assembly 24, the rotation of the clamping member 21 can make the lower tooth part 2121 move along the surface of the flange 93 towards the connection between the flange 93 and the main body of the barrel 90, thereby improving the reliability of the lower tooth part 2121 hooking the flange 93.

[0051] Referring to Figure 4 In some embodiments, the support frame 10 comprises a base 11 and a lifting rod 12 connected to the base 11, the base 11 has a moving structure 101, the lifting rod 12 extends in the up-down direction, the clamping mechanism 20 is slidingly connected to the lifting rod 12, and the driving mechanism 30 can drive the lifting mechanism to slide up and down relative to the lifting rod 12. The lifting rod 12 can provide guidance for the up-down movement of the clamping mechanism 20. Specifically, the lifting rod 12 can be provided with two opposite sliding channels, the connecting member 23 can comprise two connecting rods 231 and a cross beam connecting the two connecting rods 231, the two connecting rods 231 are slidingly connected to one sliding channel respectively, and the clamping member 21 is connected to the cross beam through the connecting rod assembly 24. Among them, the cross beam can be provided with two, respectively connected to the upper end and the lower end of the two connecting rods 231, and the abutting member 22 is connected to the lower end cross beam.

[0052] Referring to Figure 4 In some embodiments, the support frame 10 further comprises a handrail 13 connected to the lifting rod 12 and having a hand holding part convenient for hand holding, and the operator can push the barrel transfer device by pushing the hand holding part.

The abutting surface is not perpendicular to the horizontal plane, but is inclined to the horizontal plane and matches the barrel side wall 91 of the barrel 90, which can improve the stability of the abutting plate 222 abutting the barrel 90. The abutting surface extends along an arc path and matches the barrel side wall 91 of the barrel 90, so that the abutting surface limits the barrel side wall 91 of the barrel 90 in the left-right direction to avoid the barrel 90 from shaking in the left-right direction. The connecting shaft 221 can be adjusted in position in the front-back direction and the up-down direction to adapt to the size of different barrels 90.

The pedal 34 can drive the driving rod 32 to move upward through reciprocating movement, so as to drive the connecting piece 23 to move upward through the chain 35. In this way, the driving mechanism 30 can realize the upward movement of the connecting piece 23 through its own mechanical structure, thereby saving energy. The driving rod 32 is driven to move upward through the pedal 34 to drive the chain 35, so as to pull the connecting rod 231 to move upward through the chain 35, thereby making the operation more labor-saving. The chain 35 can make the upward movement distance of the connecting rod 231 twice the upward movement distance of the driving rod 32, thereby improving the upward movement speed of the connecting rod 231. The chain 35 can be connected to the crossbeam of the connecting rod 231.

[0055] Optionally, the driving base 31 can be in a cylindrical shape, and a plurality of clamping positions can be arranged inside the driving base 31. When the pedal 34 is stepped on, one step can make the driving rod 32 move upward by one clamping position. The pedal 34 can be connected to a third elastic member 341. The third elastic member 341 can drive the pedal 34 to reset through its own elastic force. After the pedal 34 is reset, the pedal 34 can be stepped on again, so as to make the driving rod 32 move upward by one clamping position again. In this way, the upward movement of the driving rod 32 can be realized. When the driving rod 32 needs to move downward, the clamping positions inside the driving base 31 can be adjusted to make the clamping positions avoid the downward movement path of the driving rod 32, so as to make the driving rod 32 move downward to the starting position.

[0056] It should be noted that the first elastic member, the second elastic member and the third elastic member 341 can all be springs.

[0057] The above only describes several specific embodiments of the present application, and only specifically describes the technical principles of the present application. These descriptions are only for the purpose of explaining the principles of the present application, and cannot be interpreted as limiting the protection scope of the present application in any way.
