[0002] Lifting is a device or tool that lifts, moves, and positions heavy objects by hoisting. It is commonly used in industries such as construction, manufacturing, and logistics, and is especially common in high-altitude operations or situations that are difficult to transport by traditional means. The lifting device can ensure the safe and efficient movement and positioning of heavy objects, reduce manpower consumption, and improve work efficiency. When transporting barrel-shaped objects, existing lifting equipment usually has two splints on both sides, which clamp and fix the barrel-shaped objects before moving. The existing splints are in a fixed state and cannot automatically change the clamping angle when adjusted according to the diameter of the barrel, resulting in an incomplete fit during clamping, poor clamping effect, and a certain risk of falling off when encountering barrels with smooth outer surfaces. For this reason, a lifting device for a material tank is designed to solve the above-mentioned problems. Summary of the Invention

[0014] A method for hoisting a material tank hoisting device comprises the following steps:

[0015] S1. The outer square tube is driven to make the hanging plate reach the designated position. When the outer square tube moves upward, the telescopic clamping arm and the arc-shaped clamping plate are driven to move inward synchronously. After the arc-shaped clamping plate moves inward and contacts the outer surface of the barrel, when the outer square tube continues to move upward, the arc-shaped clamping plate can clamp the barrel and lift the barrel to move upward along with the outer square tube.

[0016] S2. When the outer square tube, hanging plate and bucket reach the next designated position, the outer square tube moves downward to place the bucket on the ground. When the outer square tube continues to move downward, the arc-shaped splint moves outward and is in an open state.

[0017] Compared with the prior art, the present invention has the following advantages: when the crane is working, it can drive the outer square cylinder to move up and down, and when the outer square cylinder moves upward, it can drive the corresponding two telescopic clamping arms and the arc-shaped clamping plate to move inward synchronously. When the arc-shaped clamping plate moves inward and contacts the material barrel, the outer square cylinder continues to move upward, which can enable the arc-shaped clamping plate to have an inward clamping force, thereby clamping and fixing the material barrel. The arc-shaped clamping plate has an inward clamping force, which can clamp and fix the material barrel. After clamping and fixing the material barrel, it can move upward synchronously with the outer square cylinder, thereby lifting and transporting the material barrel to the designated position. When the position of the arc-shaped clamping plate needs to be adjusted according to the diameter of the barrel, the two arc-shaped clamping plates can be swung outward by driving the threaded rod to rotate. When the arc-shaped clamping plate moves outward, it will flip inward, which can change the angle of the arc-shaped clamping plate. Even when the arc-shaped clamping plate clamps inward again, the clamping force is always toward the center of the barrel, so that the barrel is subjected to more uniform force, the clamping is more close and stable, thereby improving the clamping effect. By arranging an arc-shaped clamping plate that can swing outward and flip inward at the same time, the arc-shaped clamping plate can complete the clamping, fixing and transportation work for barrels with different diameters.

DETAILED DESCRIPTION

[0034] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0035] like Figures 1-15 As shown, the present invention provides a lifting device for a material tank, including a hanging plate 1, an outer square tube 8 that can move up and down is installed on the upper end of the hanging plate 1, and telescopic clamping arms are provided on both sides of the lower end of the hanging plate 1, and when the outer square tube 8 moves upward, it can form a structure in which the two telescopic clamping arms move inward; a clamping seat 47 is provided on the inner side of the lower end of the two telescopic clamping arms, and two arc-shaped clamping plates 67 are installed on the clamping seat 47, and a rotatable threaded rod 57 is also installed on the clamping seat 47, and when the threaded rod 57 rotates, it can form a structure in which the two arc-shaped clamping plates 67 swing outward and flip inward.

[0036] like Figures 1-12As shown, the hanging plate 1 is used to install the entire device. A hanging ring 10 is provided at the upper end of the outer square tube 8. The hanging ring 10 is used to connect to the crane. When the crane is working, it can drive the outer square tube 8 to move up and down. When the outer square tube 8 moves upward, it can drive the corresponding two telescopic clamping arms and the arc-shaped clamping plate 67 to move inward synchronously. When the arc-shaped clamping plate 67 moves inward to contact the barrel, the outer square tube 8 continues to move upward to enable the arc-shaped clamping plate 67 to have an inward clamping force, thereby clamping and fixing the barrel. After clamping and fixing the barrel, it can move upward synchronously with the outer square tube 8, thereby moving and transporting the barrel to a specified position; the clamping seat 47 is used to support the installation of the arc-shaped clamping plate 67, the threaded rod 57, etc. Parts, the arc-shaped clamping plate 67 is used to clamp and fix the barrel. When the position of the arc-shaped clamping plate 67 needs to be adjusted according to the diameter of the barrel, the two arc-shaped clamping plates 67 can be rotated by driving the threaded rod 57 to swing outward. When the arc-shaped clamping plate 67 moves outward, it will flip inward, which can change the angle of the arc-shaped clamping plate 67. Even when the arc-shaped clamping plate 67 clamps inward again, the clamping force is always toward the center of the barrel, so that the barrel is more evenly stressed and the clamping is more stable, thereby improving the clamping effect. By setting up the arc-shaped clamping plate 67 that can swing outward and flip inward at the same time, the arc-shaped clamping plate 67 can complete the clamping, fixing and transportation work for barrels of different diameters.

[0037] The lower end of the hanging plate 1 is slidably connected to a horizontal plate 7 on both sides, and the telescopic clamping arms are installed on the corresponding horizontal plates 7. The inner ends of the two horizontal plates 7 are fixed with a first sliding pin 6. The front and rear sides of the upper end of the hanging plate 1 are respectively hinged with two crossed pry bars 3, and the upper ends of the two pry bars 3 are respectively hinged with a pull rod 4. The upper ends of the two pull rods 4 are respectively hinged on the front and rear end surfaces of the outer square tube 8. The middle part of the upper end surface of the hanging plate 1 is fixed with an inner square rod 9, and the outer square tube 8 is slidably connected to the outer surface of the inner square rod 9. The lower ends of the pry bars 3 are provided with a key groove 5 that cooperates with the first sliding pin 6.

[0038] like Figure 3 and Figure 4 As shown, the outer square tube 8 can slide up and down on the surface of the inner square rod 9. The inner square rod 9 is set to limit the outer square tube 8 to move up and down only on the upper end of the hanging plate 1; the horizontal plate 7 can slide left and right on the inner wall of the hanging plate 1. When the hanging plate 1 moves left and right, it can drive the telescopic clamping arm and the arc clamping plate 67 to move left and right; the installation and shape of the pry bar 3, the pull rod 4, the first sliding pin 6, and the key groove 5 are as shown Figure 3As shown, when the outer square tube 8 moves upward, it can drive the upper end of the pull rod 4 to move upward, and the upper end of the pull rod 4 will drive the pry bar 3 to flip upward. The lower ends of the two pry bars 3 can drive the cross plate 7 to move inward under the cooperation of the key groove 5 and the first sliding pin 6, that is, the corresponding telescopic clamping arm and the arc clamping plate 67 move inward, which can clamp and fix the barrel. After the arc clamping plate 67 clamps and fixes the barrel, when the outer square tube 8 continues to move upward, the arc clamping plate 67 can clamp the barrel and move upward synchronously, thereby driving the barrel to the specified position; the lower end surface of the hanging plate 1 is fixed with a buffer pad 2 The buffer pad 2 can reduce the impact between the hanging plate 1 and the barrel, thereby protecting the device; after the barrel reaches the specified position, when the outer square tube 8 moves downward, the barrel can be placed on the ground, and when the outer square tube 8 continues to move downward, the hanging plate 1 can be moved downward and contact the upper end of the barrel. Under the support and blocking of the barrel, the hanging plate 1 can be restricted from continuing to move downward. At this time, when the outer square tube 8 continues to move downward, it will drive the two corresponding horizontal plates 7, telescopic clamping arms, and arc-shaped clamping plates 67 to move outward. The arc-shaped clamping plates 67 can move outward to move away from the barrel and no longer clamp and fix.

[0039] The left and right sides of the upper end of the hanging plate 1 are provided with a snap device, and the snap device includes an L-shaped clip 18. The lower sides of the left and right end surfaces of the outer square tube 8 are fixed with hanging plates 12 that match the L-shaped clip 18. When the outer square tube 8 moves downward, the snap device can be opened to move the L-shaped clip 18 inward. When the outer square tube 8 moves downward again, the snap device can be closed to move the L-shaped clip 18 outward.

[0040] like Figure 5-Figure 7When the outer tube 8 continues to move downward, the latch device can be driven to close, and the L-shaped clamping plate 18 moves outward to open. At this time, the L-shaped clamping plate 18 is no longer in the upper position of the material barrel. When the outer tube 8 moves upward, it can drive the curved splint 67 to move inward, clamping and fixing the material barrel and lifting it upward, and the material barrel is lifted again, which can be used in a cycle.

[0041] The snap-fit ​​devices also include a track plate 14, and two side plates 13 are fixedly connected on the left and right sides of the upper end surface of the hanging plate 1. The track plates 14 are slidably connected to the inner walls of the corresponding two side plates 13. Guide plates 15 are fixedly connected on the front and rear sides of the inner end surface of the track plate 14. Long inclined grooves 16 are provided on the two guide plates 15. The L-shaped card plates 18 are slidably connected to the upper end surface of the hanging plate 1, and the front and rear end surfaces of the L-shaped card plates 18 are fixed with second sliding pins 17 that match the long inclined grooves 16.

[0042] like Figure 5-Figure 7As shown, the L-shaped card plate 18 can slide left and right on the upper end surface of the hanging plate 1, and the track plate 14 can slide up and down on the inner wall of the side plate 13, and the side plate 13 can limit and support the track plate 14 so that it can only move up and down; through the cooperation of the provided guide plate 15, the long inclined groove 16 and the second sliding pin 17, when the track plate 14 moves up and down, the guide plate 15 can be driven to move up and down, and when the guide plate 15 moves up and down, it can drive the L-shaped card plate 18 to move left and right, that is, move inward or outward through the engagement with the second sliding pin 17. When the two L-shaped card plates 18 move inward, they can block the hanging plate 12 from moving upward. When the two L-shaped card plates 18 move outward, they can be misaligned with the hanging plate 12, that is, they no longer block the hanging plate 12 from moving upward.

[0043] The left and right sides of the upper end surface of the hanger plate 1 are fixed with first springs 19 that cooperate with the track plate 14, and the left and right sides of the upper end surface of the hanger plate 1 are also hinged with limit links 20, and the upper ends of the limit links 20 are fixed with cylinders 21, and the inner walls of the cylinders 21 are slidably connected with first live pins 23, and the inner walls of the bottom ends of the cylinders 21 are fixed with second springs 22. The outer end surfaces of the track plate 14 are provided with track grooves that cooperate with the first live pins 23, and the track grooves include short vertical grooves 26, V-shaped grooves 27, long vertical grooves 24 and first oblique grooves 25. When the first live pin 23 engages with the long vertical grooves 24, the track plate 14 can be locked in the top position, and when the first sliding pin 6 engages with the V-shaped grooves 27, the track plate 14 can be locked in the bottom position; the left and right end surfaces of the outer square tube 8 are fixed with pressure rods 11 that cooperate with the track plate 14.

[0044] like Figure 7-Figure 9 As shown, the first spring 19 always has an upward thrust on the track plate 14, so that the track plate 14 can be in the top position under normal conditions; the first movable pin 23 can be slidably connected to the inner wall of the cylinder 21 left and right, and the second spring 22 always has an inward thrust on the first movable pin 23, so that the first movable pin 23 can be in a pop-up state under normal conditions. Even if the first movable pin 23 can engage with the track groove under normal conditions, the limit link 20 can limit and support the first movable pin 23 to move back and forth only within a specified height; the setting of the track groove is as shown in FIG. Figure 7 or Figure 8As shown, the inner wall of the bottom end of the track groove is respectively fixed with a first wedge block 28, a second wedge block 29 and a third wedge block 30. The first wedge block 28 is installed at the connection between the long vertical groove 24 and the first inclined groove 25, the second wedge block 29 is arranged at the connection between the short vertical groove 26 and the V-shaped groove 27, and the third wedge block 30 is arranged at the connection between the V-shaped groove 27 and the long vertical groove 24. The first wedge block 28, the second wedge block 29 and the third wedge block 30 are all provided with an inclined surface at one end and a straight surface at the other end. Through the cooperation of the inclined surface, the straight surface and the first movable pin 23, the first movable pin 23 can be moved along the specified path. When the outer square tube 8 moves from top to bottom, the outer square tube 8 and the pressure rod 11 move downward to squeeze the track plate 14 to move downward. At this time, the track plate 14 moves downward. The top moves downward, and the first live pin 23 is on the inner wall of the lower end of the long vertical groove 24. The downward movement of the track plate 14 can make the first live pin 23 slide on the inner wall of the long vertical groove 24. When the track plate 14 moves downward until the first wedge block 28 meets the first live pin 23, the first live pin 23 can slide to the inner wall of the first inclined groove 25 under the obstruction of the first wedge block 28, that is, the first live pin 23 enters the inner wall of the first inclined groove 25. When the track plate 14 continues to move downward, the first live pin 23 can enter the inner wall of the short vertical groove 26 from the inner wall of the first inclined groove 25. When the track plate 14 continues to move downward to the bottom, the first live pin 23 can slide to the top position of the short vertical groove 26, that is, enter the inner wall of the V-shaped groove 27, and meet the second wedge block 29. When the first movable pin 23 is completely in the inner wall of the V-groove 27 and is out of contact with the second wedge block 29, the first movable pin 23 can be moved out to the inner wall of the cylinder 21 under the elastic force of the second spring 22, that is, the first movable pin 23 can contact the inner wall of the bottom end of the track groove again. When the outer square cylinder 8 and the pressure rod 11 move upward and no longer squeeze the track plate 14, the track plate 14 can move upward under the elastic force of the first spring 19. When the track plate 14 moves upward from the bottom, the first movable pin 23 is engaged with the V-groove 27 and blocked by the direct surface of the second wedge block 29, and the first sliding pin 6 can slide into the V-groove 27. When the outer tube 8 and the hanging plate 12 continue to move upward, the L-shaped clamping plate 18 and the hanging plate 1 are driven to move upward synchronously, and the corresponding telescopic clamping arms and the arc clamping plates 67 are in the outermost open state. After the device moves to the specified position, that is, when the hanging plate 1 is placed on the upper surface of the barrel, the outer tube 8 and the pressure rod 11 continue to move downward, and the pressure rod 11 can squeeze the track plate 14 downward again. When the track plate 14 continues to move downward, the first movable pin 23 can slide from the inner wall of the V-shaped groove 27 to the inner wall of the long vertical groove 24.When the first movable pin 23 meets the third wedge block 30, the inclined surface of the third wedge block 30 can squeeze the first movable pin 23 into the inner wall of the cylinder 21 again. When the first movable pin 23 completely enters the inner wall of the long vertical groove 24, it can disengage from the third wedge block 30. At this time, the first movable pin 23 can be moved out of the cylinder 21 again under the elastic force of the second spring 22 and contact the inner wall of the bottom end of the track groove again. When the outer square cylinder 8, the pressure rod 11, etc. move upward, the corresponding track plate 14 will move upward and reset under the elastic force of the first spring 19. At this time, the first movable pin 23 will slide on the inner wall of the long vertical groove 24 and slide to the bottom end position of the long vertical groove 24. At this time, the track plate 14 is in the topmost position and locked. The corresponding two L-shaped clamping plates 18 are in the outermost end position and no longer prevent the hanging plate 12 from moving upward. That is, at this time, the outer square cylinder 8 can continue to move upward to make the two telescopic clamping arms and the arc clamping plates 67 move inward to clamp and close. , after clamping the barrel, lift it upward; by providing the first wedge block 28, the first movable pin 23 can enter the inner wall of the first inclined groove 25 from the inner wall of the long vertical groove 24, and by providing the second wedge block 29, the first movable pin 23 can enter the inner wall of the V-shaped groove 27 from the inner wall of the short vertical groove 26. Under the direct obstruction of the second wedge block 29, the first movable pin 23 can be prevented from entering the inner wall of the short vertical groove 26 from the inner wall of the V-shaped groove 27. By providing the third wedge block 30, The first movable pin 23 can enter the inner wall of the long vertical groove 24 from the inner wall of the V-shaped groove 27, so that the first movable pin 23 can only move along the long vertical groove 24, the first inclined groove 25, the short vertical groove 26, and the V-shaped groove 27 in this order. That is, when the track groove and the first movable pin 23 are engaged, the track plate 14 can be locked when it is at the bottom or top position, that is, the corresponding L-shaped clamping plate 18 is at the innermost or outermost end, and the locking device is in a stable open or closed state.

[0045] The outer surface of the threaded rod 57 is threadedly connected to a threaded seat 58 that is slidably connected to the clamp seat 47. The upper end of the threaded seat 58 is hinged to two short connecting rods 59. The inner wall of the clamp seat 47 is fixed with a rebounder 48. The upper end of the outer surface of the rebounder 48 is rotatably connected to two rocker rods 60. The short connecting rods 59 are hinged to the corresponding rocker rods 60. The arc-shaped clamps 67 are installed on the corresponding rocker rods 60.

[0046] like Figure 12 and Figure 15As shown, the outer surface of the threaded rod 57 is rotatably connected to two bearing seats, and the bottom ends of the bearing seats are fixed to the upper end surface of the clamping seat 47. The limiting threaded rod 57 can only rotate on the clamping seat 47, and the first handle 44 is fixed to the end surface of one side of the threaded rod 57. The function of the first handle 44 is to facilitate driving the threaded rod 57 to rotate; the threaded seat 58 can be slidably connected to the inner wall of the clamping seat 47 left and right. When the threaded rod 57 rotates, it can drive the threaded seat 58 to move left or right, that is, the two threaded seats 58 move inward or outward, and the threaded connection between the threaded rod 57 and the threaded seat 58 has a self-locking function, that is, when the threaded rod 57 does not rotate, the corresponding threaded seat 58 position is fixed, and the inner end of the short connecting rod 59 is hinged to the upper end of the threaded seat 58 The outer ends of the short connecting rods 59 are hinged on the rocker rods 60, and the rocker rods 60 are rotatably connected to the outer surface of the rebounder 48, so that the rocker rods 60 can swing left and right, that is, the two rocker rods 60 can swing inward or outward; when the first handle 44 is driven, the threaded rod 57 can be driven to rotate, and when the threaded rod 57 rotates, the threaded seat 58 can be driven to move inward or outward. When the threaded seat 58 moves inward or outward, the short connecting rod 59 is hinged with the rocker rod 60, and the two rocker rods 60 can be driven to move outward to open or inward to close. When the two rocker rods 60 move synchronously outward or inward, the arc splint 67 can be driven to move inward or outward, thereby adjusting the specific position of the arc splint 67 according to the diameter of the barrel.

[0047] The rocker arms 60 are hinged with pry seats 63, and the arc-shaped splints 67 are fixed to the corresponding pry seats 63. The inner walls of the rocker arms 60 are slidably connected to long connecting plates 61. The rocker arms 60 are also provided with first connecting rods 62. One end of the first connecting rod 62 is hinged to the corresponding long connecting plate 61, and the other end of the first connecting rod 62 is hinged to the corresponding pry seats 63. The inner walls of the long connecting plates 61 are fixed with second movable pins 64. The outer surfaces of the rebounders 48 are fixed with fan-shaped rail plates 65, and the fan-shaped rail plates 65 are provided with two sections of reducing grooves 66 that cooperate with the second movable pins 64.

[0048] like Figure 15As shown, the long connecting plate 61 can slide left and right on the inner wall of the rocker arm 60. Through the hinge connection of the pry seat 63 and the first connecting rod 62, when the long connecting plate 61 moves left and right, the pry seat 63 can be driven to swing inward or outward, that is, the corresponding arc splint 67 can swing inward or flip outward, and the direction of the arc splint 67 can be changed when the arc splint 67 flips inward or outward. When the rocker arm 60 swings left and right, the corresponding long connecting plate 61, the pry seat 63, and the arc splint 67 can be driven to swing outward or inward synchronously. When the long connecting plate 61, the second live pin 64, etc. follow the rocker arm 60 to swing, When the second movable pin 64 is engaged with the reducing groove 66, the second movable pin 64 and the long connecting plate 61 will slide left and right on the inner wall of the rocker arm 60. When the second movable pin 64 and the long connecting plate 61 slide left and right, the arc-shaped clamping plate 67 can be driven to flip inward or outward, that is, the arc-shaped clamping plate 67 can flip inward when it swings outward, or flip outward when it swings inward; that is, the direction of the arc-shaped clamping plate 67 changes automatically when it is adjusted according to the diameter of the barrel, so that it can fit more closely to the outer surface of the barrel when clamping, so that the clamping is more stable and reliable.

[0049] The lower end of the rebounder 48 is fixedly connected to the first support seat 50, and the lower end of the first support seat 50 is rotatably connected to the roller 49. The front and rear end surfaces of the clamping seat 47 are slidably connected to the U-shaped plate 52. The front and rear end surfaces of the first support seat 50 are fixedly connected to the connecting plate 51. The upper end of the connecting plate 51 is fixed to the corresponding U-shaped plate 52. The inner wall of the U-shaped plate 52 is slidably connected to the L-shaped supporting plate 53. The inner side ends of the two L-shaped supporting plates 53 are fixedly connected to the fourth sliding pin 54. The front and rear end surfaces of the clamping seat 47 are provided with side rail grooves 55 that match the fourth sliding pin 54.

[0050] like Figure 13 and Figure 14As shown, the rebounder 48 is similar to a telescopic rod, which can make the first support seat 50 and the roller 49 move up and down. The roller 49 provided can reduce the friction with the ground and can be locked when it is in the topmost position or the bottommost position, which is similar to the ballpoint pen mechanism. The rebounder 48 is a prior art and will not be described in detail. The U-shaped plate 52 can be slidably connected to the inner walls of the front and rear ends of the clamp seat 47 up and down, and the L-shaped supporting plate 53 can be slidably connected to the inner wall of the U-shaped plate 52 left and right. When the U-shaped plate 52 slides upward on the clamp seat 47, it can drive the corresponding L-shaped supporting plate 53 to move upward. When the L-shaped supporting plate 53 moves upward, the second live pin 64 and the L-shaped supporting plate 53 can be engaged with the side rail groove 55. When the U-shaped plate 52 is moved downward, the L-shaped support plate 53 and the second movable pin 64 are driven to move downward. When the second movable pin 64 is moved downward, it engages with the side rail groove 55, which causes the second movable pin 64 and the L-shaped support plate 53 to move downward and inward. When the L-shaped support plate 53 moves inward to the top end, it can move to the lower end position of the barrel. When lifting, the L-shaped support plate 53 can prevent the barrel from falling off when moving downward. The L-shaped support plate 53 provided can further protect the barrel and prevent it from falling off during lifting. After the device lifts the material barrel to the specified position, the device moves downward so that the roller 49 can first contact the ground. When the roller 49 continues to move downward after contacting the ground, the first support seat 50 and the connecting plate 51 can push the U-shaped plate 52 to slide upward on the inner wall of the clamp seat 47, and the rebounder 48 contracts. When the U-shaped plate 52 moves upward, it can drive the L-shaped support plate 53 to move upward and outward at the same time, that is, the L-shaped support plate 53 is away from the material barrel. When the material barrel moves downward to contact and be placed on the ground, the rebounder 48 contracts to the shortest state and is in a locked position, that is, the corresponding L-shaped support plate 53 can be in a stable state at the outermost end. When the outer square tube 8 continues to move downward, due to When the outer tube 8 moves downward to the bottom position, the corresponding arc-shaped splint 67 moves to the outermost end, the snap-fit ​​device opens and the two L-shaped clamping plates 18 are at the innermost end. At this time, when the outer tube 8 continues to move upward, the hanging plate 12 can drive the L-shaped clamping plate 18, the hanging plate 1, etc. to move upward synchronously. At this time, the arc-shaped splint 67 is in the open state, and the rebounder 48 is in the retracted state, that is, the corresponding L-shaped support plate 53 is at the outer end.When the outer tube 8 continues to move to the upper end position of the next bucket to be hoisted, the outer tube 8 continues to move downward to the bottom end, that is, the roller 49 contacts the ground, the hanging plate 1 contacts the upper end surface of the bucket, and the outer tube 8 continues to move downward to close the buckle device. When the outer tube 8 moves upward, it can drive the telescopic clamping arm, the arc clamping plate 67, etc. to move inward synchronously, so that the arc clamping plate 67 clamps the bucket and fixes it. When the outer tube 8 continues to move upward, the arc clamping plate 67 can clamp the bucket and lift it upward. At this time, the rebounder 48 is squeezed again and can pop out downward. When the outer tube 8, the arc clamping plate 67, the bucket, etc. continue to move upward and are out of contact with the ground, the rebounder 48 can drive the L-shaped support plate 53 to move inward at the lower end when it pops out downward, so that the L-shaped support plate 53 moves to the lower end position of the bucket again. After the rebounder 48 pops out, it can make the L-shaped support plate 53 be at the innermost designated position. At this time, the L-shaped support plate 53 can prevent the bucket from falling off.

[0051] The telescopic clamping arms each include a side clamping plate 31 and an inner clamping plate 32, both of which are slidably connected to the inner wall of the side clamping plate 31, and the side clamping plates 31 are slidably connected to the corresponding cross plate 7; the inner walls at the front and rear ends of the side clamping plates 31 are slidably connected to a movable control plate 34, and the upper sides of the inner end surfaces of the two control plates 34 are fixedly connected to a driving plate 37, and the inner walls of the upper ends of the side clamping plates 31 are slidably connected to a first latch 40, and the lower ends of the first latch 40 are fixedly connected to a third sliding pin 38. The driving plate 37 is provided with an oblique key groove 39 that cooperates with the third sliding pin 38, and the lower end surface of the cross plate 7 is provided with a plurality of first latch grooves 42 that cooperate with the first latch pin 40; the lower sides of the inner end surfaces of the two control plates 34 are fixedly connected to a second latch pin 41, and the front and rear end surfaces of the inner clamping plates 32 are provided with a plurality of second latch grooves 43 that cooperate with the second latch pin 41.

[0052] like Figure 10 and Figure 11As shown, the clamping seat 47 is installed at the lower end of the corresponding inner clamping plate 32, and the inner clamping plate 32 can slide up and down on the inner wall of the side clamping plate 31, so that the telescopic clamping arm can be extended and retracted up and down, and the length of the telescopic clamping arm can be adjusted according to the height of the clamped barrel; the side clamping plate 31 can be slidably connected to the inner wall of the cross plate 7 left and right, so that the telescopic clamping arm and the arc clamping plate 67 can move left and right, and the initial position of the telescopic clamping arm and the arc clamping plate 67 can be adjusted according to the diameter of the barrel. Through the provision of the telescopic clamping arm, it is possible to adapt to clamping barrels of different diameters; short guide rods 35 are fixed on both sides of the upper and lower surfaces of the front and rear ends of the side clamping plate 31, and the control plate 34 is slidably connected to the outer surfaces of the two short guide rods 35. The short guide rods 35 provided can limit the control plate 34 to only move forward and backward The third spring 36 is also sleeved on the outer surface of the short guide rod 35. The third spring 36 always has an inward driving force on the control plate 34, so that the control plate 34 is in the innermost end position under normal conditions; the upper side of the outer end surface of the two control plates 34 is fixedly connected to the pull ring 33, the pull ring 33 passes through the front and rear end surfaces of the side clamping plate 31 and is slidably connected to the inner wall of the side clamping plate 31. When the two pull rings 33 are driven to move outward, the two control plates 34 can be driven to move outward and the third spring 36 is compressed; the first bayonet 40 can be slidably connected to the inner wall of the side clamping plate 31 up and down. When the two control plates 34 move outward, the two drive plates 37 can be driven to move outward. When the drive plate 37 moves outward, it passes through the oblique key slot 39 When the second latch 41 is engaged with the second slot 43, the inner plate 32 can slide up and down on the inner wall of the side plate 31, that is, adjust the height of the telescopic clamping arm; when the two pull rings 33 are driven to move outward, the control plate 34 can be driven to move outward, that is, the first latch 40 is engaged with the first slot 42 again. When the pull ring 33 is released, the control plate 34 can be moved inwardly to reset under the elastic force of the third spring 36, that is, the corresponding first latch 40 moves upwardly and engages with the first latch groove 42 again, and the second latch 41 moves inwardly and engages with the second latch groove 43 again, thereby fixing the length and left and right position of the telescopic clamping arm again; the outer side of the lower end of the inner clamping plate 32 is rotatably connected to the worm 45, the lower end of the worm 45 is meshed with a worm gear 46, and the clamping seat 47 is coaxially fixed to the corresponding worm gear 46, as shown in FIG. Figure 12When the crank 56 is driven, the worm 45 can be driven to rotate. When the crank 56 is driven, the worm 45 can be driven to rotate by meshing with the worm wheel 46. When the worm 45 rotates, the worm wheel 46 and the clamping seat 47 can be driven to rotate. When the clamping seat 47 and the arc clamping plate 67 clamp the barrel, the rotation of the clamping seat 47 can drive the barrel to turn over. The barrel turning over can pour out the material at the specified position. The engagement of the worm wheel 46 and the worm 45 also has a self-locking function, that is, when the worm 45 does not rotate, the corresponding worm wheel 46 and the clamping seat 47 are in a fixed state, that is, the position of the arc clamping plate 67 is fixed and will not rotate and move, so that the barrel can be stably clamped. The clamping seat 47 can also be fixed to the inner clamping plate 32, and an adaptive setting can be made according to specific needs.

[0053] A method for hoisting a material tank hoisting device comprises the following steps:

[0054] S1. The hanging plate 1 is brought to the designated position by driving the outer square tube 8. When the outer square tube 8 moves upward, the telescopic clamping arm and the arc-shaped clamping plate 67 are driven to move inward synchronously. After the arc-shaped clamping plate 67 moves inward to contact the outer surface of the barrel, the outer square tube 8 continues to move upward. The arc-shaped clamping plate 67 can clamp the barrel and lift it to move upward along with the outer square tube 8.

[0055] S2. When the outer square tube 8, the hanging plate 1 and the bucket reach the next designated position, the outer square tube 8 moves downward to place the bucket on the ground. When the outer square tube 8 continues to move downward, the arc-shaped splint 67 moves outward and is in an open state.

[0056] When the present invention is in use, when the crane is working, it can drive the outer square tube 8 to move up and down. When the outer square tube 8 moves upward, it can drive the corresponding two telescopic clamping arms and the arc-shaped clamping plate 67 to move inward synchronously. When the arc-shaped clamping plate 67 moves inward and contacts the barrel, the outer square tube 8 continues to move upward, which can make the arc-shaped clamping plate 67 have an inward clamping force, thereby clamping and fixing the barrel. The arc-shaped clamping plate 67 has an inward clamping force, which can clamp and fix the barrel. After clamping and fixing the barrel, it can move upward synchronously with the outer square tube 8, thereby lifting and transporting the barrel to the specified position. When it is necessary to When the diameter of the barrel is adjusted to the position of the arc clamping plate 67, by driving the threaded rod 57 to rotate, the two arc clamping plates 67 can be swung outward, and the arc clamping plates 67 will flip inward when moving outward, which can change the angle of the arc clamping plates 67. Even when the arc clamping plates 67 are clamped inward again, the clamping force is always toward the center of the barrel, so that the barrel is subjected to more uniform force and the clamping is more stable, thereby improving the clamping effect. By setting up an arc clamping plate 67 that can swing outward and flip inward at the same time, the arc clamping plate 67 can complete the clamping, fixing and transportation work for barrels of different diameters.
