Description
Technical Field
The utility model relates to an oil drum tongs mechanism.
Background
Barreled oil is the oil commonly used in industrial production, adopts the manpower transport mostly in the in-process of loading or transporting, because the oil drum is cylindrical and weight is heavier, the manpower is carried comparatively difficultly, and because there is not the hanging point on the oil drum surface also hardly use crane auxiliary transport, has influenced work efficiency.
The structure of oil drum is columniform ladle body, and the ladle body both ends are equipped with two circular shape closing caps, and the closing cap directly adopts the seam structure to be connected and sealed with the ladle body, and the seam structure can form the epitaxial convex circle of circumference on the ladle body outer wall.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that an oil drum tongs mechanism is provided, the crane can snatch the oil drum through it and carry out supplementary transport, raises the efficiency.
In order to solve the technical problem, the utility model provides an oil drum gripper mechanism, which comprises an upper ring, wherein a handle is bridged on the upper side of the upper ring, at least three chains with the same specification are circumferentially and evenly distributed on the lower side of the upper ring, one end of each chain is connected with the ring, the other end of each chain is arranged in a downward inclined manner, the intersection points of the lower ends of all the chains and the horizontal plane are arranged on the same horizontal circumference, the circumference is taken as a reference circle, the circle center of the reference circle and the circle center of the upper ring share a vertical line, the vertical line is taken as an axis, a gripper is arranged on the lower side of each chain, each gripper comprises a C-shaped fastener and a movable inner hook, one side of the gripper close to the axis along the horizontal direction is taken as the inner side and the side far away from the axis is taken as the outer side, the opening of the C-shaped fastener is inward, a strip-shaped through groove, the hook handle is in a long strip shape, the hook claw is arranged on one side of the hook handle in the length direction, the hook claw is bent inwards, one side of the hook handle, which is far away from the hook claw in the length direction, is in pin joint with the lower side of the chain, one side of the hook handle, which is close to the hook claw, penetrates through the through groove and is arranged in the C-shaped fastener, and the hook handle is hinged with the C-shaped fastener at the through groove of the C-shaped fastener.
For the sake of simple explanation problem, it is right below the oil drum tongs mechanism all be this mechanism for short.
The using method of the mechanism comprises the following steps: articulate the lifting hook and the handle of crane, the oil drum that will wait to lift by crane is vertical to be arranged, then position four tongs and sting mouthful department in the oil drum upside circumference that waits to lift by crane, the upper end that will C shape fastener closely pastes with the inboard of stinging mouthful department and pastes, the lower side of C shape fastener pastes with the outside bucket wall of oil drum and pastes, lean on the lower side of hook and the protruding circle of oil drum to leaning on, the crane upwards lifts up the upper ring this moment, make the chain be the tensioning state, the hook handle is unanimous with chain length direction this moment, pulling force along chain length direction can be in the hook department and decompose into horizontal inward pressure and vertical ascending pulling force to the oil drum, the oil drum will be occluded by the tongs like this, continue upwards to pull this moment, can lift the oil drum.
The advantages of the mechanism are that: the crane can snatch the oil drum through this mechanism and carry out supplementary transport, raises the efficiency, because the downside of hook and oil drum bulge loop supports to leaning on, the hook can not the slippage when the crane upwards promotes, and the hook handle can be convenient for change after the tongs uses wearing and tearing for a long time with the chain pin joint, can say the tongs to the oil drum of equidimension not in addition and install on the different positions of chain, and is nimble changeable.
In order to achieve better use effect of the mechanism, the preferable scheme is as follows:
Preferably, a weight is arranged at the position of the hook handle corresponding to the upper side of the hinge point.
The weight block is on the upside of pin joint, and under the chain lax state, the weight block has the trend that drives one side downstream that the hook claw was kept away from to the hook handle to can make the hook claw keep away from the oil drum, the convenient tongs of dismantling after hoist and mount are finished.

Detailed Description
Referring to fig. 1-3, the oil drum gripper mechanism comprises an upper ring 1, a handle 2 is connected to the upper side of the upper ring 1 in a spanning manner, four chains 3 of the same specification are uniformly distributed on the lower side of the upper ring 1 in the circumferential direction, one end of each chain 3 is connected with the ring, the other end of each chain 3 is arranged in a downward inclined manner, the intersection points of the lower ends of all the chains 3 and the horizontal plane are on the same horizontal circumference, the circumference is set as a reference circle, the center of the reference circle and the center of the upper ring 1 share a vertical line, the vertical line is set as a central axis, a gripper 4 is arranged on the lower side of each chain 3, each gripper 4 comprises a C-shaped fastener 41 and a movable inner hook 42, one side of the gripper 4 close to the central axis along the horizontal direction is set as an inner side far from the central axis and is set as an outer side, the opening of the C-shaped fastener 41 is inward, a strip-shaped through groove is arranged in the, the hook handle 421 is a long strip, the hook claw 422 is arranged on one side of the hook handle 421 in the length direction, the hook claw 422 bends inwards, one side of the hook handle 421 away from the hook claw 422 in the length direction is in pin joint with the lower side of the chain 3, one side of the hook handle 421 close to the hook claw 422 passes through the through groove 411 and is arranged inside the C-shaped buckle 41, the hook handle 421 is hinged with the C-shaped buckle 41 at the through groove 411 of the C-shaped buckle 41, and the weighting block 423 is arranged on the position of the hook handle 421 corresponding to the upper side of the hinge point.
The using method of the mechanism comprises the following steps: the lifting hook of the crane is connected with the lifting handle 2 in an articulated mode, an oil drum 5 to be lifted is vertically arranged, then four grippers 4 are positioned at a circumferential seaming position on the upper side of the oil drum 5 to be lifted, the upper side end of the C-shaped fastener 41 is tightly attached to the inner side of the seaming position, the lower side end of the C-shaped fastener 41 is attached to the outer side drum wall of the oil drum 5, the hook claw 422 is abutted to the lower side of the convex ring 51 of the oil drum 5, the crane lifts the upper ring 1 upwards to enable the chain 3 to be in a tensioning state, the hook handle 421 is consistent with the length direction of the chain 3 at the moment, the pulling force in the length direction of the chain 3 can be decomposed into horizontal inward pressure and vertical upward pulling force on the oil drum 5 at the position of the hook claw 422, and therefore the oil drum 5 can be occluded by the grippers 4 and continues to.
the advantages of the mechanism are that: the crane can snatch oil drum 5 through this mechanism and carry out supplementary transport, raises the efficiency, because the downside of hook 422 and 5 collars 51 of oil drum leans on, and hook 422 can not the slippage when the crane upwards promotes, and hook 421 can be convenient for change after 4 long-term use wearing and tearing of tongs with 3 pin joints of chain, can say that tongs 4 are installed on 3 different positions of chain to the oil drum 5 of equidimension not in addition, and is nimble changeable.
Weight 423 is at the upside of pin joint, and under 3 lax states of chain, weight 423 has the trend that drives one side downstream that hook 421 kept away from hook 422 to can make hook 422 keep away from oil drum 5, make things convenient for dismantling of tongs 4 after the hoist and mount are finished.
