[0048] Embodiment

[0049] The embodiment provides a clamping device for unwinding of a cable reel. It should be noted that the core scheme of the embodiment is to modify the conventional clamping device to improve the clamping range of the reel thickness. Referring to Figure 2As shown in the drawings, the conventional clamping device comprises a frame 1, a first clamping piece 2 and a second clamping piece 3. The frame 1 is in a frame structure and is hollow in the middle. The first clamping piece 2 comprises an extension section 21 and a first insertion section 22. The extension section 21 is installed on the frame 1, and the first insertion section 22 is connected with the extension section 21 for insertion into a winding drum. A first baffle 23 is arranged between the extension section 21 and the first insertion section 22. The diameter of the first baffle 23 is greater than that of the extension section 21 and the first insertion section 22 respectively. When the first insertion section 22 is inserted into the winding drum, the baffle abuts against the end of the winding drum, thereby limiting the winding drum. The extension section 21 is extended or retracted to clamp winding drums of different thicknesses. The second clamping piece 3 is installed on the frame 1 and opposite to the first clamping piece 2. The second clamping piece 3 is used for insertion into the winding drum. When clamping the winding drum, the first insertion section 22 and the second clamping piece 3 are inserted into the two ends of the winding drum respectively, thereby clamping the winding drum. The winding drum rotates relative to the first clamping piece 2 and the second clamping piece 3 during unwinding.

[0050] With reference to Figure 1 As shown in the drawings, the first insertion section 22 is lengthened by installing the lengthening section 4 on the first insertion section 22, thereby clamping winding drums with a thickness less than the clamping range of the original equipment.

[0051] Specifically, with reference to Figure 3 As shown in the drawings, the lengthening section 4 comprises a second insertion section 41, a lengthening sleeve 42 and a fastening assembly. The second insertion section 41 is used for insertion into the winding drum. When the lengthening section 4 is installed, the second insertion section 41 and the second clamping piece 3 are inserted into the two ends of the winding drum respectively, thereby clamping the winding drum.

[0052] Specifically, with reference to Figure 3 As shown in the drawings, one end of the lengthening sleeve 42 is connected with the second insertion section 41, and the other end is provided with an insertion slot 43 for accommodating the first insertion section 22. With reference to Figure 4 and Figure 5 As shown in the drawings, the fastening assembly comprises a clamping jaw 44 and a fastening sleeve 45. With reference to Figure 7As shown, the clamping jaw 44 comprises a hinged section 441 and a clamping section 442, one end of the hinged section 441 is inserted into the mounting groove 46 and hinged with the elongated sleeve 42, and the other end extends out of the mounting groove 46. Specifically, the tail end of the hinged section 441 extends to the outside of the axial direction of the hinged section 441, and also extends to the outside of the radial direction of the hinged section 441. The clamping section 442 is connected to the extended end of the hinged section 441 and is bent relative to the hinged section 441, and one end of the clamping section 442 away from the hinged section 441 is provided with a pressing end face 443 for abutting against the first baffle plate 23. The fastening sleeve 45 is threadedly sleeved on the elongated sleeve 42, and one end of the fastening sleeve 45 towards the clamping jaw 44 is provided with a guide section 47, the inner diameter of the guide section 47 gradually decreases in the direction away from the clamping jaw 44.

[0053] When the elongated section 4 is installed, the fastening sleeve 45 is screwed in the direction close to the clamping section 442, and the hinged section 441 is gradually pressed under the action of the guide section 47, so that the hinged section 441 rotates towards the axis direction of the elongated sleeve 42, thereby making the clamping section 442 rotate to abut the pressing end face 443 against the first baffle plate 23, so that the elongated section 4 is connected and fastened with the first clamping piece 2. Correspondingly, when the elongated section 4 is disassembled, the fastening sleeve 45 is screwed in the reverse direction, and the elongated section 4 can be disassembled. The disassembly process is simple, convenient and easy to operate.

[0054] During the loading or disassembly process of the reel, the elongated section 4 needs to be moved forward or backward by the first clamping piece 2, and the elongated section 4 is fastened with the first clamping piece 2 by the fastening assembly, which can improve the stability of the elongated section 4 and avoid the elongated section 4 from falling off during the movement process.

[0055] The clamping device for unwinding the cable reel provided in the embodiment can improve the clamping range of the clamping device by installing the elongated section 4 on the first clamping piece 2, so as to clamp the reel with smaller thickness; without modifying the equipment itself, the processing difficulty is small, the cost is low, and it is simple and convenient. The elongated sleeve 42 is fastened on the first baffle plate 23 by the fastening assembly, which avoids the elongated section 4 from separating from the first clamping piece 2 during the extension and retraction process of the first clamping piece 2, ensures the stability of the elongated section 4, and the installation and disassembly process of the elongated section 4 is simple and convenient.

[0056] Specifically, continuing to refer to Figure 7As shown, a torsion spring 445 is arranged between the hinge section 441 and the lengthened sleeve 42, and the torsion spring 445 has a torsion force for rotating the hinge section 441 towards the outside of the mounting groove 46. When the guide section 47 is not in abutment with the hinge section 441, the spacing between the pressing end face 443 and the axis of the lengthened sleeve 42 is greater than the radius of the first baffle 23, and the clamping section 442 is conveniently passed through the first baffle 23. When the guide section 47 is in abutment with the hinge section 441, the hinge section 441 is pressed to rotate, and the spacing between the pressing end face 443 and the axis of the lengthened sleeve 42 is less than the radius of the first baffle 23. The lengthened section 4 and the first clamping section are limited and fastened.

[0057] Specifically, the pressing end face 443 is provided with a rubber pad 444. When the fastening sleeve 45 presses the hinge section 441 and the pressing end face 443 is in abutment with the first baffle 23, the pressing end face 443 and the first baffle 23 cannot necessarily maintain parallelism. By pressing the rubber pad 444, the rubber pad 444 is deformed non-uniformly according to the actual relative state between the pressing end face 443 and the first baffle 23, so as to increase the contact area and improve the friction and the fastening effect.

[0058] Specifically, continuing to refer to Figure 3 As shown, the diameter of the lengthened sleeve 42 is greater than the diameter of the second insertion section 41, so that a stepped surface 48 for abutting against the winding drum is formed between the lengthened sleeve 42 and the second insertion section 41. The sleeve is positioned by abutting against the stepped surface.

[0059] Specifically, continuing to refer to Figure 2 As shown, the second clamping member 3 comprises a fixed section 31, a third insertion section 32 and a second baffle 33. The fixed section 31 is mounted on the rack 1. The third insertion section 32 is connected with the fixed section 31 and is used for being inserted into the sleeve. The second baffle 33 is located between the fixed section 31 and the third insertion section 32 and is used for abutting against the winding drum to position the winding drum.

[0060] Specifically, referring to Figure 2 As shown, the first insertion section 22 is provided with a first guide inclined surface 24, and the diameter of the first guide inclined surface 24 gradually decreases towards the direction away from the first baffle 23. By arranging the first guide inclined surface 24, the first insertion section 22 is more easily inserted into the winding drum when the winding drum is loaded. The second insertion section 41 is provided with a second guide inclined surface 49, and the diameter of the second guide inclined surface 49 gradually decreases towards the direction away from the lengthened sleeve 42. Similarly, the second insertion section 41 is more easily inserted into the winding drum by the second guide inclined surface 49.

[0061] Specifically, referring to Figure 6As shown, the telescopic section 21 comprises a fixed sleeve 25, a rotating shaft 26 and a moving shaft 27. The fixed sleeve 25 is mounted on the frame 1, and a limiting bolt 28 is arranged on the fixed sleeve 25. The rotating shaft 26 is rotatably connected with the frame 1 through a bearing 201, and the rotating shaft 26 is rotatably inserted into the fixed sleeve 25. The moving shaft 27 is provided with a threaded hole at one end for threadedly connecting with the rotating shaft 26, and the other end of the moving shaft 27 extends out of the fixed sleeve 25 and is connected with the first baffle 23. The moving shaft 27 is provided with a limiting slot 29 extending in the axial direction, and the limiting bolt 28 is inserted into the limiting slot 29 to limit the rotation of the moving shaft 27. By limiting the rotation of the moving shaft 27 through the limiting bolt 28, the moving shaft 27 is driven to move along the axial direction when the rotating shaft 26 is rotated, so as to realize the telescoping of the telescopic section 21.

[0062] Specifically, continuing to refer to Figure 2 As shown, the rotating shaft 26 is connected with a rotating handle 202. By operating the rotating handle 202, the rotating shaft 26 is conveniently rotated.

[0063] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not contradict, they should be considered within the scope of the present disclosure.

[0064] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
