DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] The utility model provides Figure 1-5 A cable drum lifting tool shown in the figure comprises a connecting plate 1, with clamping arms 2 symmetrically hinged at both sides of the bottom of the connecting plate 1, a driving mechanism is arranged on the top of the connecting plate 1, and a connecting piece is arranged on the side opposite to the multiple clamping arms 2 at the output end of the driving mechanism, and the connecting piece is used to transmit the power of the driving mechanism to control the angle opening and closing of the clamping arms 2;

[0030] Specifically, the driving mechanism includes a driving motor 3, which is fixedly connected to the top of the connecting plate 1, and the output end of the driving motor 3 passes through the middle of the connecting plate 1. The through end of the driving motor 3 is provided with a driving screw 301 for driving the connecting member to operate.

[0031] It should be noted that a through hole is opened in the middle of the connecting plate 1 in the vertical direction, so that the output end of the driving motor 3 can be inserted, and the end of the driving motor 3 with the output end is fixed to the top of the connecting plate 1 by welding.

[0032] Furthermore, the connecting piece includes:

[0033] A threaded collar 4, the threaded collar 4 is threadedly sleeved on the outer wall of the driving screw 301;

[0034] A connecting block 201, the connecting block 201 is sleeved between the two arms of the clamping arm 2;

[0035] The connecting rod 5 has two ends hinged to the outer wall of the threaded collar 4 and the outer wall of the connecting block 201 respectively.

[0036] Furthermore, a rotating ring 401 is provided on the outer wall of the threaded ring 4, and the rotating ring 401 is used to hinge the connecting rod 5. Through the setting of the rotating ring 401, after the threaded ring 4 and the driving screw 301 are threadedly matched, the threaded ring 4 can rotate stably without affecting the connection between the threaded ring 4 and the connecting rod 5.

[0037] In the setting of this scheme, the drive screw 301 is driven to rotate by the output end of the drive motor 3. At this time, the threaded ring 4 is threadedly matched with the drive screw 301, and the threaded ring 4 moves vertically following the rotation direction of the drive screw 301. At this time, the connecting rod 5 follows the traction of the rotating ring 401 to rotate in an articulated manner, and at the same time cooperates with the traction of the connecting block 201, so that the connecting block 201 drives the clamping arm 2 to change the opening and closing angle.

[0038] Specifically, a support frame 101 is provided at the top of the connecting plate 1 and sleeved on the outer wall of the driving motor 3 , and a lifting ring 102 is provided at the top of the support frame 101 , through which a lifting mechanism can be connected.

[0039] A plurality of clamping jaws 6 are disposed on the front and back sides of the clamping arm 2 , and a combination mechanism is disposed between the plurality of clamping jaws 6 and between the clamping jaws 6 and the clamping arm 2 , and the combination mechanism is used for rotation adjustment of the clamping jaws 6 .

[0040] Specifically, the combined institutions include:

[0041] A combination ring 7, which is arranged on the front and back sides of the clamp arm 2 and on the side of the clamp jaw 6 away from the clamp arm 2;

[0042] The combined column 8 is arranged on the side of the clamping jaw 6 close to the clamping arm 2. The end of the combined column 8 away from the clamping jaw 6 is slidably inserted and connected to the inner wall of the combined ring 7. The outer wall diameter of the combined column 8 is the same as the inner wall diameter of the combined ring 7, thereby ensuring that the combined column 8 and the combined ring 7 are tightly inserted.

[0043] Furthermore, a plurality of positioning holes 701 are formed around the outer wall of the combination ring 7 , and locking pieces are symmetrically provided on the outer wall of the combination column 8 . The locking pieces are inserted into the positioning holes 701 at different positions to position the angle of the clamp 6 .

[0044] Furthermore, the locking member includes a locking plug 801, one end of which is slidably inserted and connected to the outer wall of the combination column 8, and the other end of the locking plug 801 is inserted and connected to one of the positioning holes 701, and a supporting spring 802 is arranged between the insertion point of the locking plug 801 and the combination column 8.

[0045] Furthermore, limiting grooves are provided at the top and bottom ends of the insertion point of the combination column 8 and the locking plug 801, and limiting sliders 80101 are fixedly connected to the top and bottom ends of the locking plug 801, and the limiting sliders 80101 are slidably inserted and connected in the limiting grooves.

[0046] It should be noted that when adjusting the setting angle of the clamp 6, first press the locking block 801 in the direction close to the combined column 8. At this time, the locking block 801 is subjected to force and drives the limiting slider 80101 to move in the direction close to the combined column 8. After the locking block 801 slides out of the corresponding positioning hole 701, the clamp 6 can be rotated, and the combined column 8 is driven to rotate synchronously. Under the above operation, according to the angle to be set, the clamp 6 is rotated to the required angle. Under the support of the supporting spring 802, the locking block 801 moves in the direction away from the combined column 8, and is inserted into the corresponding positioning hole 701 to complete the insertion positioning.

[0047] In the setting of this scheme, the locking member can also be implemented by a bolt structure, that is, the bolt structure passes through the positioning hole 701 and is threadedly connected with the combined column 8, thereby completing the positioning of the rotation angle of the combined column 8, thereby limiting the rotation angle of the clamp 6.

[0048] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
