DETAILED DESCRIPTION

[0019] The technical scheme in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model.

[0020] As Figure 1 and Figure 2 The utility model provides a technical scheme: a copper wire shaft overturning hoisting tool, including mobile hook 1, copper wire shaft 2 and guide mechanism 3, guide mechanism 3 includes guide disc 31, the inner side wall of guide disc 31 is fixedly connected with the suspension rod 32 of mobile hook 1 sleeve joint, the inner side wall of guide disc 31 is located below the symmetry rotation sleeve joint of suspension rod 32 and is provided with guide wheel 33, is provided with arc-shaped guide rail 4 in the middle sliding sleeve joint of two groups of guide wheels 33, the inner side wall of arc-shaped guide rail 4 is provided with the limiting mechanism 5 of limiting overturning to copper wire shaft 2, the end of arc-shaped guide rail 4 is fixedly connected with the pull hook 34 of the side of guide mechanism 3 for facilitating the pull of arc-shaped guide rail 4, and copper wire shaft 2 is placed in the just below of guide mechanism 3.

[0021] The combination of the guide disc 31 and the suspension rod 32 provides a stable support point for the mobile hook 1, while ensuring flexibility during hoisting. The setting of the guide wheel 33 further enhances the guidance and support of the arc-shaped guide rail 4 and the copper wire shaft 2 during the overturning action, making the overturning process more stable and controllable. The limiting mechanism 5 on the inner side wall of the arc-shaped guide rail 4 can accurately limit the copper wire shaft 2, ensuring that the copper wire shaft 2 does not deviate from the predetermined trajectory during the overturning process, thereby avoiding the loosening or damage of the copper wire shaft. The setting of the pull hook 34 allows the operator to easily pull the arc-shaped guide rail 4, thereby controlling the overturning progress of the copper wire shaft 2, greatly simplifying the operation process and improving work efficiency.

[0022] As shown in Figure 3 and Figure 4 , the limiting mechanism 5 includes a first mounting frame 51 fixedly connected to the inner side wall of the arc-shaped guide rail 4. The first mounting frame 51 is fixedly connected with a second mounting frame 52 inserted into the inside of the copper wire shaft 2 at one end away from the arc-shaped guide rail 4. The inner side wall of the first mounting frame 51 is fixedly connected with a driving shaft 53. The end of the driving shaft 53 located outside the outer wall of the first mounting frame 51 is fixedly connected with a pressure arm 531 placed at a right angle to the driving shaft 53. The outer side wall of the driving shaft 53 is fixedly connected with a cam 54 inside the first mounting frame 51. The interiors of the first mounting frame 51 and the second mounting frame 52 are connected. The interior of the first mounting frame 51 is slidingly connected with a pressure plate 55 at one side of the cam 54, and the pressure plate 55 is pressed by the cam 54. The interior of the second mounting frame 52 is fixedly connected with a positioning disc 561 at one side of the pressure plate 55 away from the cam 54. The side of the pressure plate 55 close to the positioning disc 561 is fixedly connected with an extension rod 56.

[0023] The fixed connection of the first mounting frame 51 and the second mounting frame 52, and their clever cooperation with the arc-shaped guide rail 4 and the copper wire shaft 2, ensure the stability of the copper wire shaft 2 during the overturning process. The cooperation of the driving shaft 53, the pressure arm 531 and the cam 54 provides flexible driving force for the limiting mechanism 5. The operator can rotate the pressure arm 531 to drive the driving shaft 53 and the cam 54 to rotate, thereby controlling the compression degree of the pressure plate 55. The close cooperation of the positioning disc 561 and the pressure plate 55, as well as their clamping action on the copper wire shaft 2, enables the limiting mechanism 5 to provide continuous limiting effect during the overturning process.

[0024] As shown in Figure 3 and Figure 4As shown, the one end of the extension rod 56 away from the pressing disc 55 is fixedly connected with an extrusion head 562, the inner bottom end of the second mounting frame 52 is fixedly connected with a plurality of limiting guide rails 521 in an annular array, the inside of the plurality of limiting guide rails 521 is slidably connected with a guide frame 57, the outer side wall of the guide frame 57 is fixedly connected with a protruding rod 571, the outer side wall of the guide frame 57 located outside the outer wall of the protruding rod 571 is fixedly connected with a second spring 572, and the second spring 572 is fixedly connected with the inner side wall of the second mounting frame 52, the side of the plurality of guide frames 57 close to the extrusion head 562 is provided with an inner groove 573, the protruding rod 571 penetrates through the inside of the second mounting frame 52, and the side of the positioning disc 561 opposite to the pressing disc 55 is fixedly connected with a first spring 563 for resetting on the outer wall of the extension rod 56.

[0025] With the above technical scheme, the setting of the extrusion head 562 makes the extension rod 56 be able to act on the guide frame 57 more uniformly when transmitting pressure, thereby improving the overall stability of the limiting mechanism 5, and meanwhile, the addition of the first spring 563 provides a good resetting function between the pressing disc 55 and the positioning disc 561, so that when the external force disappears, the pressing disc 55 can quickly return to the initial position, ready for the next limiting operation.

[0026] Working principle: since the copper wire shaft 2 is placed on the ground in a rolling manner, in order to be able to turn it over, the user can connect the mobile lifting hook 1 to the crane, then insert the second mounting frame 52 into the inside of the copper wire shaft 2, then move the pressure arm 531 to drive the driving shaft 53 to rotate, at this time the cam 54 connected with the driving shaft 53 will be extruded to the pressing disc 55 under the action of rotation, and push the extension rod 56 to move and compress the first spring 563, and the extrusion head 562 at the end of the extension rod 56 will extrude the guide frame 57, at this time the guide frame 57 will extrude the second spring 572 and move after being stressed, at this time the protruding rod 571 moves out from the inside of the second mounting frame 52 and is located at the end of the copper wire shaft 2, in order to avoid that the protruding rod 571 will automatically reset, the user can install a corresponding ratchet mechanism (the ratchet mechanism belongs to the prior art disclosed common sense, and will not be described too much here) on the outer wall of the first mounting frame 51, so that it can limit the driving shaft 53, avoiding the situation that it will reset under the influence of gravity, then pull the drag hook 34 to drive the arc-shaped guide rail 4 to do arc-shaped motion, and the arc-shaped guide rail 4 contacts with the two groups of guide wheels 33 and moves relatively, at this time the copper wire shaft 2 will be turned over under the driving of the limiting mechanism 5 and the arc-shaped guide rail 4, when it moves to the specified position, place two cushion plates under the copper wire shaft 2 to ensure that the copper wire shaft 2 has a certain gap with the ground when falling, and then the limiting of the copper wire shaft 2 is released, and the limiting mechanism 5 is moved out, at this time the copper wire shaft 2 is turned over.

[0027] The above embodiments are only used to illustrate the technical scheme of the present application, but not limit it.
