[0001] The invention relates to the field of lifting equipment, and in particular to a device for lifting a bucket. Background Art

[0002] Industrial barrels generally have a large capacity and need to be hoisted when stored or used. The existing hoisting method is to tie the barrels with ropes or chains before hoisting. However, this hoisting method is unsafe, and due to the large capacity and heavy weight of the barrels, if an accident occurs during the hoisting process (such as slipping, loosening, etc.), it will cause serious consequences, seriously threatening the personal safety of workers and environmental safety.

[0003] In industrial production, barrels are widely used and frequently used. Therefore, if the traditional bundling method is used for lifting, the production efficiency is seriously affected. In order to solve this problem, the lifting equipment for lifting barrels came into being. However, in some special cases, the movement and operation space of the lifting equipment is very limited, and the lifting needs to be carried out from the inside of the barrel. The existing lifting equipment cannot be used in these special cases. Summary of the invention

The number of the through holes 601 is consistent with the number of the lifting assembly 200, for example, three, and the through holes 601 may be waist holes.

[0034] See also Figures 3 to 7 In one embodiment of the present invention, the mounting seat 100 includes: an inner fixing sleeve 110, the inner fixing sleeve 110 is cylindrical, a connecting plate 120 is installed at the first end of the inner fixing sleeve 110, the connecting plate 120 is annular, a bottom plate 130 is installed at the second end of the inner fixing sleeve 110, a boss 111 is provided at the bottom of the inner fixing sleeve 110, and a plurality of accommodating cavities 140 are provided in the boss 111 that penetrate in the radial direction. The accommodating cavity 140 is a cavity with openings at both ends, and is used to accommodate the supporting shaft 210 and the spring 240.

A plurality of balls are distributed in the corresponding guide rails. The balls can be steel balls. The rotational positioning sleeve 300 realizes rotation through the balls.

[0036] See also Figure 5 In one embodiment of the present invention, a step 231 is provided at the end of the lifting arm 230 . The step 231 is used to clamp the inner edge 701 of the barrel 700 .

[0037] See also Figure 7In one embodiment of the present invention, the lifting assembly 200 includes: a supporting shaft 210, a mounting frame 220 and a lifting arm 230. The supporting shaft 210 is slidably mounted in the accommodating chamber 140. A spring 240 is arranged on the outer periphery of the supporting shaft 210. The spring 240 is located in the accommodating chamber 140. The mounting frame 220 is correspondingly mounted on the bottom plate 130. The lifting arm 230 is rotatably connected to the mounting frame 220 by screws. The lifting arm 230 is rotatably connected to the supporting shaft 210 by screws. A flange 211 is arranged at the end of the supporting shaft 210. The accommodating chamber 140 includes a first chamber 141 and a second chamber 142. The first chamber 141 is connected to the second chamber 142. The inner diameter of the first chamber 141 is larger than the inner diameter of the second chamber 142. The spring 240 is located in the first chamber 141. When the rotating positioning sleeve 300 rotates, the spring 240 pushes the supporting shaft 210 into the fifth groove 310, and the supporting shaft 210 drives the lifting arm 230 to retract inward. Since the depth of the fifth groove 310 gradually deepens from both ends to the middle, when the rotating positioning sleeve 300 rotates to the middle position of the fifth groove 310 corresponding to the supporting shaft 210, the supporting shaft 210 retracts to the maximum limit; the rotating positioning sleeve 300 continues to rotate, the fifth groove 310 pushes the supporting shaft 210 to move inward, and the supporting shaft 210 drives the lifting arm 230 to open.

[0038] See also Figure 2 , Figures 8 to 9 In one embodiment of the present invention, the inner wall of the rotation positioning sleeve 300 is provided with a plurality of fifth grooves 310 corresponding to the accommodating cavity 140, the depth value of the end of the fifth groove 310 is zero, the maximum depth of the fifth groove 310 is located in the middle of the fifth groove 310, and the depth of the fifth groove 310 smoothly transitions from the end to the maximum value. The number of the fifth grooves 310 corresponds to the number of the lifting components 200.

[0039] See also Figures 7 to 9 In one embodiment of the present invention, two parallel plug-in seats 212 are provided at the end of the supporting shaft 210 facing the rotation positioning sleeve 300, and a pin shaft 250 is installed on the plug-in seat 212. The pin shaft 250 is fixed to the plug-in seat 212 through a shaft retaining ring. The axial direction of the pin shaft 250 is perpendicular to the axial direction of the supporting shaft 210. A wear-resistant sleeve 260 is provided on the outer periphery of the pin shaft 250, and the wear-resistant sleeve 260 is located between the two plug-in seats 212. The outer wall of the wear-resistant sleeve 260 protrudes to the outside of the pin shaft 250 and the plug-in seat 212, and the supporting shaft 210 contacts the fifth groove 310 through the wear-resistant sleeve 260. The friction between the fifth groove 310 and the wear-resistant sleeve 260 is rolling friction, which reduces the wear between the two.

[0040] During operation, the crane hook is hoisted on the lifting lug 510 of the sling, and the lifting and lowering of the crane hook drives the lifting and lowering of the lifting lug 510. During the descent process, the guide cylinder 430 plays a guiding role in the vertical direction. The external fixing sleeve 420 connected to the lifting lug 510 drives the guide body 421 (pin shaft) to move up and down, and the up and down movement of the guide body 421 drives the rotation positioning sleeve 300 to rotate. The rotation positioning sleeve 300 is a structure with a fifth groove 310 on the inner side, and during its rotation process, the support shaft 210 can be moved forward and backward. A flange 211 is provided at the rear end of the support shaft 210, and a spring 240 is installed on the outer periphery of the support shaft 210. The spring 240 is located between the flange and the junction, and the junction refers to the junction of the first chamber 141 and the second chamber 142. When the rear end of the supporting shaft 210 corresponds to the fifth groove 310 of the rotating positioning sleeve 300, the spring 240 pushes the supporting shaft 210 toward the groove, and the lifting arm 230 is pulled backward by the supporting shaft 210. At this time, the lifting arm 230 can smoothly pass through the inner edge of the barrel 700, and the sling descends and enters the barrel 700. During the descent process, the bottom plate 130 falls on the upper edge of the barrel 700. At this time, the hook drives the lifting ear 510 to rise. During the ascending process, the guide body 421 moves upward, driving the rotating positioning sleeve 300 to rotate, and the supporting shaft 210 withdraws from the groove and moves inward, driving the lifting arm 230 to lift. At this time, the lifting arm 230 can hook the inner edge 701 of the barrel 700. The hook continues to rise, and the sling lifts the barrel 700. Therefore, the present invention effectively overcomes some practical problems in the prior art and has high utilization value and use significance.

[0041] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
