Description

Technical Field

[0001] The invention relates to the technical field of lifting tools, in particular to a protective oil drum lifting sling. Background Art

[0002] Oil is one of the essential materials for the normal operation of various mechanical equipment in various enterprises or units. These oils generally need to be loaded into oil drums after leaving the factory and then transported. At present, the oil drum hook is generally directly hooked on the flange at the end of the oil cylinder, and the oil drum is lifted vertically, resulting in an unreliable connection between the hook and the oil drum. In addition, the oil drum is prone to shaking when it is lifted, and the oil drum is easy to fall off from the hook when shaking, which can easily cause the hook and the flange of the oil drum to fall off, causing accidents.

[0003] Based on this, the present invention designs a protective oil drum lifting sling to solve the above problems. Summary of the Invention

[0004] The object of the present invention is to provide a protective oil drum lifting sling to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: a protective oil drum lifting sling, comprising a bottom plate, a placement plate rotatably connected to the top of the bottom plate, two clamping groups provided above the bottom plate, the two clamping groups being symmetrically arranged about the placement plate;

[0006] The two gears are symmetrically arranged with respect to the rack rod, and the two gears are fixedly connected to the connecting disk, and the two connecting disks are rotatably connected to the first wedge plates, the two first wedge plates are fixedly connected to the top of the cross plate, and the two gears are fixedly connected to the resisting rod, and the driving plate is fixedly connected to the push rod, and the push rod is used to push the first wedge plate;

[0007] The clamping group further includes a fixing group, which is used to fix the two gears.

[0008] As a further solution of the present invention, the fixing group includes two insertion rods and fixing holes, and there are several fixing holes. The fixing holes are evenly opened on the two connecting plates. The two insertion rods are slidably connected to the fixing holes. The two insertion rods are fixedly connected to a connecting rod. The two connecting rods are respectively slidably connected to the cross plate in the horizontal direction. The two connecting rods are fixedly connected to a third spring for their reset. A second wedge plate is provided under the two connecting rods. The two second wedge plates are slidably connected to the cross plate in the vertical direction, and the bottom ends of the two second wedge plates pass through the bottom plate.

[0009] As a further solution of the present invention, two limit plates are slidably connected inside the placement plate; the two limit plates are fixedly connected with a fourth spring for their reset, and the two limit plates are symmetrically arranged about the placement plate.

[0010] As a further solution of the present invention, the limiting plate is L-shaped, and the top end of the limiting plate is inclined.

[0011] As a further solution of the present invention, the driving plate is fixedly connected to a limiting block.

[0012] As a further solution of the present invention, the ends of the resisting rods are fixedly connected with rubber blocks.

[0025] See also Figure 1-6 The present invention provides a technical solution: a protective oil drum lifting sling, comprising a bottom plate 1, a placement plate 2 being rotatably connected to the top of the bottom plate 1, two clamping groups being arranged above the bottom plate 1, and the two clamping groups being symmetrically arranged about the placement plate 2;

[0026] The clamping group includes a support plate 3, which is fixedly connected to the top of the base plate 1, and the support plate 3 is slidably connected to the driving plate 4 in the vertical direction; the driving plate 4 is fixedly connected to a first spring 6 for its reset, and the driving plate 4 is provided with a hanging hole 5, and the support plate 3 is slidably connected to the cross plate 7 in the horizontal direction; the cross plate 7 is fixedly connected to a second spring 8 for its reset, and the cross plate 7 is slidably connected to a rack rod 9 in the vertical direction, and the rack rod 9 is fixedly connected to the driving plate 4, and the rack rod 9 is meshed with two gears 10, and the two gears 10 are symmetrically arranged about the rack rod 9, and the two gears 10 are fixedly connected to a connecting disk 18, and the two connecting disks 18 are rotatably connected to a first wedge plate 11, and the two first wedge plates 11 are fixedly connected to the top of the cross plate 7, and the two gears 10 are fixedly connected to a resisting rod 25, and the driving plate 4 is fixedly connected to a push rod 12, and the push rod 12 is used to push the first wedge plate 11;

[0027] The clamping group further includes a fixing group, which is used to fix the two gears 10 .

[0028] When the above scheme is put into actual use, the oil drum is manually dumped and then placed on the placement plate 2, or the oil drum is placed on the placement plate 2 by an oil drum transporter, and then the placement plate 2 is rotated to ninety degrees. When the placement plate 2 is not rotated, the diameter of the center of the placement plate 2 is greater than half of the height of the oil drum. At this time, there is still a certain distance between the two ends of the oil drum and the resistance rod 25. Then, the hook is passed through the lifting hole 5. Because the oil drum and the bottom plate 1 are heavy, when the hook rises, it will first drive the two driving plates 4 to slide upward along the support plate 3 and stretch the first spring 6. When the driving plate 4 slides, it will drive the rack rod 9 and the push rod 12 to rise. When the push rod 12 rises, it will push the two first wedge plates 11 and the cross plate 7 to move quickly in the direction close to the oil drum, so that the resistance rod 25 quickly moves to the position that fits the two ends of the oil drum. At this time, the driving plate 4 continues to drive When the rack rod 9 rises, the rack rod 9 meshes with the two gears 10 when it rises, causing the two resisting rods 25 to rotate, thereby causing the ends of the two resisting rods 25 to rotate to a position in contact with the inner ring of the oil drum, and supporting the gear 10 through the connecting plate 18. When the resisting rod 25 contacts the inner ring of the oil drum, the rack rod 9 and the two gears 10 are in a locked state. When the hook continues to rise, the driving plate 4 cannot continue to slide upward along the supporting plate 3. Therefore, the hook can only lift the driving plate 4 after the resisting rod 25 contacts the inner ring of the oil drum. After the base plate 1 is separated from the ground, the fixing group fixes the two gears 10, so that the two gears 10 cannot rotate. Even if the hook shakes after lifting the driving plate 4, the base plate 1 and the oil drum, the two gears 10 are in a state of being unable to rotate, thereby ensuring the stability of the oil drum during the lifting process.

[0029] When the oil drum is hoisted, the placement plate 2, the bottom plate 1 and the support plate 3 provide effective support for the oil drum, ensuring the stability of the oil drum during the hoisting process. The four resisting rods 25 can block the position of the inner ring of the oil drum near the bottom after entering the inner ring of the oil drum, so that even if the hook slides during the hoisting process, it will not affect the oil drum. The fixing group can quickly fix the gear 10 when the oil drum is hoisted, so that the gear 10 is in a fixed state, so that the gear 10 will not rotate even when the oil drum is rotated 360 degrees, thereby preventing the oil drum from falling and causing safety hazards.

[0030] When the oil drum is hoisted to the designated location, at the moment the bottom plate 1 contacts the ground, the fixing group will quickly release the rotation of the gear 10. Under the action of the first spring 6 and the second spring 8, the driving plate 4 and the cross plate 7 will also return to their initial positions. Then you only need to rotate the oil drum to ninety degrees, and then remove the oil drum from the placement plate 2.

[0031] As a further solution of the present invention, the fixing group includes two insertion rods 13 and fixing holes 19, there are several fixing holes 19, and the fixing holes 19 are evenly opened on the two connecting plates 18. The two insertion rods 13 are slidably connected to the fixing holes 19, and the two insertion rods 13 are fixedly connected to the connecting rod 14. The two connecting rods 14 are respectively slidably connected to the cross plate 7 in the horizontal direction. The two connecting rods 14 are fixedly connected to the third spring 15 for their reset. A second wedge plate 16 is provided under the two connecting rods 14. The two second wedge plates 16 are slidably connected to the cross plate 7 in the vertical direction, and the bottom ends of the two second wedge plates 16 pass through the bottom plate 1.

[0032] When the fixing group is working, when the base plate 1 is hoisted, the base plate 1 is above the ground. When the base plate 1 stays on the ground, the second wedge plate 16 will slide upward and push the connecting rod 14 to slide along the cross plate 7. When the connecting rod 14 slides, it will also squeeze the third spring 15. When the connecting rod 14 slides, it will drive the insertion rod 13 to move. After the connecting rod 14 compresses the third spring 15 to the limit position, the insertion rod 13 is outside the fixing hole 19, so that the insertion rod 13 is released from the fixing hole 19.

[0033] When the base plate 1 is lifted, the ground loses its resistance to the second wedge plate 16. At this time, the elastic relaxation of the third spring 15 will drive the connecting rod 14 to reset. During the reset process of the connecting rod 14, the second wedge plate 16 will be pressed down until the third spring 15 relaxes to the limit position and the second wedge plate 16 slides down to the limit position. At this time, the second wedge plate 16 will not push the connecting rod 14. At this time, the insertion rod 13 also enters the fixing hole 19, and the connecting plate 18 is limited by the insertion rod 13, so that the gear 10 will not rotate when the oil drum is lifted.

[0034] As a further solution of the present invention, two limit plates 17 are slidably connected inside the placement plate 2; both limit plates 17 are fixedly connected to a fourth spring 20 for resetting them, and the two limit plates 17 are symmetrically arranged about the placement plate 2.

[0035] When the above solution is working, the limiting plate 17 is slidably connected to the placement plate 2, so that the distance between the two limiting plates 17 is adjustable, so that the placement plate 2 can place oil drums of different thicknesses.

[0036] As a further solution of the present invention, the limiting plate 17 is L-shaped, and the top end of the limiting plate 17 is inclined.

[0037] As a further solution of the present invention, the driving plate 4 is fixedly connected to the limiting block 21 .

[0038] When the above solution is working, the limiting block 21 can limit the driving plate 4 to prevent the driving plate 4 from falling off from the inside of the support plate 3.

[0039] As a further solution of the present invention, both ends of the resisting rod 25 are fixedly connected to a rubber block 22 .

[0040] When the above solution is working, the rubber block 22 can buffer the resistance rod 25 and the inner ring of the oil drum when the resistance rod 25 contacts the inner ring of the oil drum.

[0041] As a further solution of the present invention, a plurality of balls 23 are rotatably connected to the top of the placement plate 2 .

[0042] When the above solution is working, the ball 23 facilitates the adjustment of the oil barrel when the oil barrel is placed on the placement plate 2, so that the center point of the oil barrel is roughly at the center position of the placement plate 2.

[0043] As a further solution of the present invention, the bottom plate 1 is provided with four strip grooves 24 , and the four second wedge-shaped plates 16 are slidably connected in the four strip grooves 24 , respectively.

[0044] When the above solution is in operation, the four strip-shaped grooves 24 enable the connecting rod 14 to slide smoothly, thereby being able to clamp oil drums of different sizes.

[0045] Working principle: manually dump the oil drum and place it on the placement plate 2, or place the oil drum on the placement plate 2 by an oil drum transporter, and then rotate the placement plate 2 to ninety degrees. When the placement plate 2 does not rotate, the diameter of the center of the placement plate 2 is greater than half of the height of the oil drum. At this time, there is still a certain distance between the two ends of the oil drum and the resistance rod 25. Then, the hook is passed through the lifting hole 5. Because the oil drum and the bottom plate 1 are heavy, when the hook rises, it will first drive the two driving plates 4 to slide upward along the support plate 3 and stretch the first spring 6. When the driving plate 4 slides, it will drive the rack rod 9 and the push rod 12 to rise. When the push rod 12 rises, it will push the two first wedge plates 11 and the cross plate 7 to move quickly toward the direction close to the oil drum, so that the resistance rod 25 quickly moves to the position that fits the two ends of the oil drum. At this time, the driving plate 4 continues to drive the rack rod 9 When the hook rises, the rack rod 9 meshes with the two gears 10 to make the two resisting rods 25 rotate, so that the ends of the two resisting rods 25 rotate to the position of contacting the inner ring of the oil drum, and the gear 10 is supported by the connecting plate 18. When the resisting rod 25 contacts the inner ring of the oil drum, the rack rod 9 and the two gears 10 are in a locked state. When the hook continues to rise, the driving plate 4 cannot continue to slide upward along the supporting plate 3. Therefore, the hook can only lift the driving plate 4 after the resisting rod 25 contacts the inner ring of the oil drum. After the base plate 1 is separated from the ground, the fixing group fixes the two gears 10 so that the two gears 10 cannot rotate. Even if the hook shakes after lifting the driving plate 4, the base plate 1 and the oil drum, the two gears 10 are in a state of being unable to rotate, thereby ensuring the stability of the oil drum during the lifting process.

[0046] When the oil drum is hoisted, the placement plate 2, the bottom plate 1 and the support plate 3 provide effective support for the oil drum, ensuring the stability of the oil drum during the hoisting process. The four resisting rods 25 can block the position of the inner ring of the oil drum near the bottom after entering the inner ring of the oil drum, so that even if the hook slides during the hoisting process, it will not affect the oil drum. The fixing group can quickly fix the gear 10 when the oil drum is hoisted, so that the gear 10 is in a fixed state, so that the gear 10 will not rotate even when the oil drum is rotated 360 degrees, thereby preventing the oil drum from falling and causing safety hazards.

[0047] When the oil drum is hoisted to the designated location, at the moment the bottom plate 1 contacts the ground, the fixing group will quickly release the rotation of the gear 10. Under the action of the first spring 6 and the second spring 8, the driving plate 4 and the cross plate 7 will also return to their initial positions. Then you only need to rotate the oil drum to ninety degrees, and then remove the oil drum from the placement plate 2.
