[0023] The utility model aims to provide a steel drum hoisting device to improve the hoisting efficiency.

[0024] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] refer to Figures 1 to 5, a steel drum lifting equipment, comprising a frame, a lifting mechanism arranged on the frame and a grabbing mechanism arranged below the lifting mechanism, the lifting mechanism comprising a guide bracket arranged on the frame crossbeam, a lower limit bracket arranged on the upper surface of the guide bracket, a lifting guide optical axis and a cylinder, a support plate arranged on the lifting guide optical axis and fixable, a support adjustment device arranged below the guide bracket and a gripper ring, the cylinder rod of the cylinder passes through the guide bracket and is connected to the gripper ring via the support adjustment device, the gripping mechanism comprises a mounting plate, a micro-guide device, a movable guide sleeve connected to the cylinder rod via a joint bearing, and a cylinder arranged The double-ear connecting shaft arm on the outer wall of the movable guide sleeve and the grabbing arm hinged with the double-ear connecting shaft arm, and the large rubber-wrapped grabber and the small rubber-wrapped grabber are respectively arranged on the grabbing arm. The grabbing arm is L-shaped, one side of which is connected to the double-ear connecting shaft arm, and the other side is connected to the large rubber-wrapped foot grabber or the small rubber-wrapped grabber. The corner of the grabbing arm is against the mounting plate, and the large rubber-wrapped grabber and the small rubber-wrapped grabber are used to clamp the steel drum. The present invention adopts cylinder assistance and its own gravity to clamp the steel drum and the rubber layer on the inner side of the rubber-wrapped grabber protects the paint surface and increases friction, ensuring that there is no slipping during the lifting process; the micro-guide device structure effectively avoids the inability to grab the barrel due to improper placement.

[0026] refer to Figure 4 The micro-guide device includes a guide connecting block, a guide square steel arranged on the guide connecting block and vertically arranged, and a bearing mounting bracket arranged at both ends of the guide square steel. The upper end of the guide connecting block is fixed to the outside of the grabber lifting ring, and the lower end of the guide connecting block is fixed to the outside of the movable guide sleeve. Bolts and gaskets for compressing springs are respectively arranged at both ends of the outer side of the guide square steel. Needle shafts are respectively arranged in the four mold grooves of the bearing mounting bracket to fix needle bearings and pass through the guide square steel. The four surfaces of the guide square steel are tangent to the needle bearing surface.

[0027] refer to Figure 2 The lifting mechanism also includes a magnetic switch arranged on the cylinder.

[0028] refer to Figure 2 The lifting mechanism also includes a proximity switch arranged on the lower limit bracket.

[0029] Furthermore, a rubber layer for increasing friction is provided on the inner sides of the large rubber-coated gripper and the small rubber-coated gripper.

[0030] refer to Figure 3 A fixed guide sleeve is arranged on the mounting plate.

[0031] refer to Figure 3 An adjustable polyurethane column is provided at the bottom of the mounting plate.

[0032] The working process of the utility model is as follows:

[0033] Lifting action: The steel drum is lifted by the lifting device to about 50mm from the lower end of the rubber-coated gripper; the cylinder stroke is 450mm to perform the extension action, driving the support plate, the gripper ring and the grabbing part downward. When the cylinder extends 420mm, the adjustment polyurethane column fixed on the support plate first contacts the surface of the steel drum, and at the same time, the support plate 1 is moved to trigger the proximity switch. Since the cylinder rod and the gripper ring adopt a suspended structure design, the release adjustment device connected to the cylinder rod can continue to extend about 30mm at this time; so the grabbing part and the lifting part are supported by the steel drum and separated from the cylinder rod in a suspended state; when the steel drum lifting device goes down, the grabbing part, the lifting part and the steel drum go down together by about 30mm, and the support plate just falls on the lower limit bracket, so that the lifting part is in contact with the fixed part of the frame, avoiding the lifting process only relying on the cylinder rod connection for lifting, increasing the reliability and stability of the lifting, and also avoiding the cylinder from being impacted by external forces and shortening the service life; the steel drum lifting device continues to go down until it is separated and the lifting is completed. Therefore, when the jacking is lifted again (the lifting stroke is certain), the error caused by the pallet or steel drum can be compensated so that the steel drum will not fall when released, thus ensuring that the steel drum and the material are not damaged.

[0034] Grabbing action: When the lifting action is completed, the proximity switch is triggered. At this time, the large rubber bag gripper and the small rubber bag gripper are at 1 / 3 of the distance from the barrel mouth of the steel barrel. The cylinder performs the extension action, and the two ears of the movable guide sleeve drive the connecting arm to pull the two grabbing arms. The two end shafts of the support plate form a lever principle to complete the action of clamping the bag and grabbing the steel barrel; the steel barrel is lowered through the jacking device for replacement, transfer and transportation.

[0035] Steel drum release: the pallet is lifted into place and the reverse action is performed.

[0036] Micro-guide device: To avoid the four steel drums being unable to be grasped due to position deviation, the cross-guide design is adopted for hoisting; when the position of the steel drum is slightly deviated, the lower part of the large rubber bag gripper and the small rubber bag gripper adopts an outward turning edge design, so that it can cut in from the edge of the steel drum and move downward. When the clamping bag is too long, lateral force will be generated. At this time, the micro-guide device structure can release this part of the force; when the steel drum is suspended in the air during hoisting, the micro-guide will automatically return to its position under the action of the compression spring force to correct the position of the steel drum. The function of the micro-guide device is realized.

[0037] Adaptive changes made according to actual needs are all within the protection scope of this utility model.

[0038] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
