The working principle for the hitch 2 is: after the copper foil roll 50 is hoisted by the hoisting tool, the situation that the two ends of the beam 1 and the two ends of the copper foil roll 50 are not in the same horizontal line can occur, and the hoisting under the situation has great potential safety hazard; in order to solve the potential safety hazard, the position of the C-shaped hanging block 201 on the beam 1 can be manually slid, so that the gravity center of the beam 1 after the copper foil roll 50 is hoisted is redistributed, and the two ends of the beam 1 and the copper foil roll 50 are enabled to return to the same horizontal line again; in order to prevent the C-shaped hanging block 201 from sliding on the beam 1 during the hoisting process, the two ends of the beam 1 are adjusted to be on the same horizontal line, and the bolts 205 are manually tightened to fix the C-shaped hanging block 201 on the beam 1 by pressing the bolts 205 against the beam 1. When the next copper foil roll 50 is hoisted, the position of the C-shaped hanging block 201 can be slightly adjusted again.

And a handle is fixedly arranged on the side surface of the baffle 4 far away from the cross beam 1. The handle is designed to facilitate the movement of the cross member 1 by a worker.

For the copper foil roll 50 in the prior art, a standard bushing 51 can be sleeved in an inner hole of a paper tube in the center of the copper foil roll 50; the function of the standard bushing 51 is: the inner bore of the paper tube in different copper foil rolls 50 may not have a high degree of fit with the bearing bar 7, and a good fit with the bearing bar 7 can be achieved by adding a standard bushing 51.

The specific working process of the invention is as follows:

when the special lifting appliance does not lift the copper foil roll 50, the state of the lifting mechanism 6 is as follows: the distance between the two sliding sleeves 8 is in a minimum state; the inner square sleeve 33, the sliding block 35 and the bearing rod 7 are inclined upwards by about 5 degrees around the rotating C shaft 22, the limit is not generated by the baffle 37 and the stop block 31, the plate spring 30 is in a compressed state, the guide block 39 is positioned in the middle of the guide groove 38, and the meshing point of the C gear 23 and the transmission rack 36 is positioned in the middle of the transmission rack 36; assume that the bearing bar 7 extends beyond the outer case 25 by a distance S1.

When the copper foil roll 50 is hoisted, the special sling upper hanging device 2 is hung on a travelling crane or KBK travelling crane device through the hanging hole 204; the hanger for the copper foil roll 50 is moved to the cut copper foil on the unloading and transferring platform, one sliding sleeve 8 is manually pulled, and then under the action of the synchronizing mechanism, the two sliding sleeves 8 synchronously move away from each other so that the distance between the bearing rods 7 in the two hoisting mechanisms 6 is adjusted to be slightly larger than the length position of the copper foil roll 50. In the stage when the two sliding sleeves 8 just start to slide away from each other, taking the adjustment mechanism 5 on the left side as shown in fig. 1 as an example, the gear a 13 rotates clockwise under the action of the fixed rack 9; after the transmission of the corresponding shafts and the bevel gears, the rotation speed of the C gear 23 is higher than that of the a gear 13, and the rotation directions of the C gear 23 and the a gear 13 are the same, so that when the a gear 13 travels a small distance on the transmission rack 36, as shown in fig. 13, the C gear 23 rotating clockwise can drive the sliding block 35 to move away from the bearing rod 7 in the inner sleeve 33 rapidly through the transmission rack 36 until the C gear 23 is meshed with the last tooth at the right end of the transmission rack 36, at this time, the rotation of the a gear 13 and the C gear 23 can not drive the sliding block 35 to move through the transmission rack 36 any more, and only the sliding block 35 is maintained in a state of moving to the limit position away from the bearing rod 7; in the process, the guide block 39 follows the slide block 35, the a spring 40 is compressed, and the B spring 41 is extended. In a state where the slide block 35 is kept moving to the limit position in the direction away from the bearing rod 7, the bearing rod 7 is extended beyond the outer sleeve 25 by a distance S2, and S2 is smaller than S1. The effect of the right-hand adjustment mechanism 5 in fig. 1 is the same as the effect of the left-hand adjustment mechanism 5.

Compared with the situation that the bearing rods 7 cannot stretch out and draw back in the process of adjusting the distance between the two bearing rods 7 in the prior art; when the two sliding sleeves 8 of the invention are pulled to move away from each other, the advantage of inserting the bearing bar 7 a part of the distance into the outer sleeve 25 is that: the distance of the worker pulling the sliding sleeve 8 to move away from each other can be saved, the workload of the worker for adjusting the distance between the two bearing rods 7 is reduced, and the efficiency for adjusting the distance between the two bearing rods 7 is improved.

After the distance between the two bearing rods 7 is adjusted to be slightly larger than the length of the copper foil roll 50, and the two bearing rods 7 are aligned with the standard bushing 51 at the center of the copper foil roll 50, the distance between the outer sleeve 25 and the port of the corresponding copper foil roll 50 is S3, and S3 is larger than S2. The sliding sleeves 8 are manually pushed to move towards the hanging device 2, and under the action of the synchronizing mechanism, the two sliding sleeves 8 synchronously move towards each other so that the bearing rods 7 in the two hoisting mechanisms 6 are inserted into the bushings 51 in the corresponding copper foil rolls 50. Taking the pushing of the adjusting mechanism 5 on the left side as shown in fig. 1 as an example, the gear a 13 rotates counterclockwise under the action of the fixed rack 9; since the rotation speed of the C gear 23 is higher than the rotation speed of the a gear 13 after the transmission of the corresponding shafts and the bevel gears, and the rotation directions of the C gear 23 and the a gear 13 are the same, when the a gear 13 travels a small distance on the transmission rack 36, as shown in fig. 13, the C gear 23 rotating counterclockwise can drive the sliding block 35 to move rapidly in the direction of the bearing rod 7 in the inner sleeve 33 through the transmission rack 36, and the rotation of the C gear 23 causes the transmission rack 36 to move through the middle point where the C gear 23 is meshed with the transmission rack 36, and then until the C gear 23 is meshed with the last tooth at the left end of the transmission rack 36, at this time, the rotation of the a gear 13 and the C gear 23 can not drive the sliding block 35 to move through the transmission rack 36 any more, but the sliding block 35 is maintained in the state of moving to the limit position in the direction of the bearing rod 7; in the process, the guide block 39 follows the slide block 35, the a spring 40 is extended, and the B spring 41 is compressed. In the state where the slide block 35 is kept moving to the limit position in the direction of the bearing rod 7, the bearing rod 7 is extended beyond the outer sleeve 25 by a distance S4, where S4 is greater than S1, that is, the portion of the bearing rod 7 inserted into the bush 51 is longer than the distance of the bearing rod 7 extended beyond the outer sleeve 25 in the initial state; the design has the advantages that: the more the bearing rod 7 is inserted into the bush 51, the more firm the bearing rod 7 lifts the copper foil roll 50 and the bearing area of the bearing rod 7 is large, and accidental damage to the copper foil roll 50 is not easy to cause. It should be further mentioned that the distance S3 is controlled to ensure that the movement direction of the outer sleeve 25 is not hindered by the copper foil roll 50 when the distance of the bearing bar 7 extending from the outer sleeve 25 reaches a maximum. The effect of the right-hand adjustment mechanism 5 in fig. 1 is the same as the effect of the left-hand adjustment mechanism 5.

Then, the weight at the two ends of the cross beam 1 can be balanced by finely adjusting the position of the hanging device 2 so as to ensure the stability and safety in the hoisting process. As shown in fig. 15, during the process of lifting the copper foil roll 50, the bearing rod 7 is relatively affected by the downward pressing of the gravity of the copper foil roll 50, and then the bearing rod 7 drives the sliding block 35 and the structure mounted on the inner square sleeve 33 to swing downward around the rotating C-axis 22; when bearing bar 7 is pushed down to horizontal position, the bottom of interior square sleeve 33 just laminates with backup pad 29, leaf spring 30 is continued to be compressed, the lower extreme of being pressed by baffle 37 contacts with the interior bottom surface of outer square sleeve 25 and is located the dog 31 front end by baffle 37, dog 31 just can restrict by baffle 37 to the direction removal of keeping away from bearing bar 7 like this, and then guaranteed that bearing bar 7 can not break away from in copper foil roll 50 at the hoist and mount in-process, avoided more that the major incident that copper foil roll 50 probably appears dropping when copper foil roll 50 tilt state appears in the hoist and mount process, protected copper foil roll 50 and guaranteed peripheral personnel's safety. In addition, because the movement of the bearing rod 7 and the sliding block 35 to the direction far away from the copper foil roll 50 is limited in the hoisting process, the position where the transmission rack 36 is meshed with the C gear 23 is locked, and further, after the transmission influence of the corresponding shaft and the bevel gear, the position where the A gear 13 is meshed with the fixed rack 9 is locked, so that the position of the sliding sleeve 8 is also locked; therefore, the positions of the two sliding sleeves 8 are locked in the hoisting process, and the safety of the hoisting process is further facilitated. After the hanging device is adjusted, the same batch basically does not need to be adjusted again.

After the copper foil roll 50 lifted on the special lifting appliance is lifted to a wooden box for loading or lifted to a platform scale for weighing, the special lifting appliance integrally moves downwards so that the bearing rod 7 is not pressed down by the gravity of the copper foil roll 50 any more, and then under the reset action of the plate spring 30, the inner square sleeve 33 drives the swinging plate 32, the sliding block 35 and the bearing rod 7 to swing upwards for resetting around the rotating C shaft 22. Then, one sliding sleeve 8 is manually pulled to enable the two sliding sleeves 8 to move away from each other, so that the adjusting mechanism 5 can completely pull out the bearing rod 7 in the hoisting mechanism 6 from the copper foil roll 50, and the specific transmission of the structures inside the adjusting mechanism 5 and the hoisting mechanism 6 refers to the situation that the two sliding sleeves 8 move away from each other by manually pulling one sliding sleeve 8.

The above-described hoisting process is repeated to hoist the next coil of copper foil 50.

In the invention, when the swinging plate 32 and the inner square sleeve 33 swing around the rotating C shaft 22 in a self-adaptive mode, the transmission rack 36 is always meshed with the C gear 23. The spring A40 and the spring B41 in the invention mainly have the functions of assisting the guide block 39 to drive the sliding block 35 to move, and ensuring the smooth sliding of the sliding block 35 in the inner square sleeve 33.

It should be understood that the present invention is not limited to the above-described embodiments, but the technical solutions and the inventive concepts of the present invention may be equally replaced or modified by other embodiments within the technical scope of the present invention.
