DETAILED DESCRIPTION

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1, reference Figures 1 to 5 , which is the first embodiment of the present invention, provides a cable drum hanger for cable laying, including a lifting mechanism 100, which includes a hanger 101, and a hanger 102 rotatably arranged on the hanger 101, and also includes a load-bearing shaft 103 fixedly arranged on the hanger 102; in this embodiment, a hanging frame is provided at the top of the hanger 101, and the device and the hanging cable of the crane can be connected through the setting of the hanging frame, and the hanger 102 can rotate outside the hanger 101 to adjust the angle of the load-bearing shaft 103.

[0033] The connecting mechanism 200 includes a connecting shaft 201; a No. 1 clamping arm 300, which includes a No. 1 turntable 301 rotatably arranged on the connecting shaft 201, and a No. 1 connecting arm 302 arranged on the No. 1 turntable 301, and also includes a triangular block 303 arranged on the No. 1 connecting arm 302; a No. 2 clamping arm 400, which includes a No. 2 turntable 401 rotatably arranged on the connecting shaft 201, and a No. 2 connecting arm 402 arranged on the No. 2 turntable 401, and also includes a triangular plate 403 arranged on the No. 2 connecting arm 402; in this embodiment, two No. 1 turntables 301 are provided, and are symmetrically arranged on both sides of the No. 2 turntable 401.

[0034] Further, the first rotating disk 301 is provided with a first connecting hole 301a, the first rotating disk 301 is provided with a first arc groove 301b and a first locking groove 301c, and the first arc groove 301b and the first locking groove 301c are connected to each other; the second rotating disk 401 is provided with a second connecting hole 401a, the second rotating disk 401 is provided with a second arc groove 401b and a first limiting groove 401c, and the second arc groove 401b and the first limiting groove 401c are connected to each other; the outer wall of the bearing shaft 103 and the inner wall of the first arc groove 301b are connected to each other. And the inner wall of the No. 2 arc groove 401b is slidably connected. In this embodiment, the No. 1 connecting hole 301a and the No. 2 connecting hole 401a are coaxial and are both rotatably connected to the connecting shaft 201. The No. 1 arc groove 301b and the No. 2 arc groove 401b have the same size, and the centers of the No. 1 arc groove 301b and the No. 2 arc groove 401b are both located at the axis of the connecting shaft 201. The No. 1 locking groove 301c is connected to the middle section of the No. 1 arc groove 301b, and the No. 1 limiting groove 401c is connected to the middle section of the No. 2 arc groove 401b.

[0035] When in use, due to the existence of the gravity of the No. 1 clamping arm 300 and the No. 2 clamping arm 400 themselves, the No. 1 clamping arm 300 and the No. 2 clamping arm 400 are connected through the connecting shaft 201, and the No. 1 clamping arm 300 and the No. 2 clamping arm 400 will have a tendency to fall. Therefore, when not hoisted, the load-bearing shaft 103 is located in the No. 1 locking groove 301c and the No. 1 limiting groove 401c.

[0036] During hoisting, the worker holds the boom 101 and controls the device to move it above the cable drum, lowers the cable to make the boom 101 go down, and the device approaches the cable drum. Through the inclined surfaces at the bottom of the triangular block 303 and the triangular plate 403, when the bottom ends of the first clamping arm 300 and the second clamping arm 400 contact the frame of the cable drum, the triangular block 303 and the triangular plate 403 collide with the frame on the cable drum. At this time, the first clamping arm 300 and the second clamping arm 400 are restrained. After the load is applied, the load-bearing shaft 103 can slide into the first arc groove 301b and the second arc groove 401b. After the load-bearing shaft 103 enters the first arc groove 301b and the second arc groove 401b, the first clamping arm 300 and the second clamping arm 400 can rotate and open with the connecting shaft 201 as the axis. Under the action of gravity, the first clamping arm 300 and the second clamping arm 400 are in cooperation with the inclined surface at the bottom of the upper triangle block 303 and the triangle plate 403. The arm 400 will expand and fall, so that the frame on the cable drum enters between the first clamping arm 300 and the second clamping arm 400. At this time, the suspension rod 101 is pulled up. Under the gravity of the first clamping arm 300 and the second clamping arm 400, the bearing shaft 103 will enter the first locking groove 301c and the first limiting groove 401c. During the lifting process, gravity acts on the triangle block 303 and the triangle plate 403, and the bearing shaft 103 is located in the first locking groove 301c. 01c and the No. 1 limit groove 401c will prevent the No. 1 clamping arm 300 and the No. 2 clamping arm 400 from rotating and expanding, so the No. 1 clamping arm 300 and the No. 2 clamping arm 400 cannot be opened, and as the lifting weight increases, the greater the force on the load-bearing shaft 103, the higher the stability between the No. 1 clamping arm 300 and the No. 2 clamping arm 400, the lifting device is easy to operate when connecting the cable reel, has high stability during lifting, and is not easy to fall off.

[0037] Specifically, the No. 1 clamping arm 300 also includes a counterweight block 304 arranged on the triangular block 303; the No. 2 clamping arm 400 also includes a hollow groove 402a arranged on the No. 2 connecting arm 402. In the present embodiment, the setting of the counterweight block 304 can increase the weight of the No. 1 clamping arm 300, and the setting of the hollow groove 402a can reduce the weight of the No. 2 clamping arm 400, so that the gravity distribution of the No. 1 clamping arm 300 and the No. 2 clamping arm 400 is more balanced, which facilitates the load-bearing shaft 103 to enter the No. 1 locking groove 301c and the No. 1 limiting groove 401c under the action of gravity.

[0038] Furthermore, a first contact surface 303a is provided on the triangular block 303; a second contact surface 403a is provided on the triangular plate 403. In the present embodiment, the arrangement of the first contact surface 303a and the second contact surface 403a facilitates the bearing of the suspended cable drum and improves the stability during the lifting.

[0039] Example 2, reference Figure 1 to Figure 9, which is the second embodiment of the present invention. Different from the previous embodiment, the first turntable 301 is provided with a second locking groove 301d, and the second locking groove 301d and the first arc groove 301b are connected to each other; the second turntable 401 is provided with a second limiting groove 401d, and the second limiting groove 401d and the second arc groove 401b are connected to each other.

[0040] In this embodiment, the No. 1 clamping arm 300 and the No. 2 clamping arm 400 are inserted into the end of the cable drum, and the No. 1 clamping arm 300 and the No. 2 clamping arm 400 are manually rotated to open, and the lifting rod 101 is pulled up, and the load-bearing shaft 103 enters the No. 2 locking groove 301d and the No. 2 limiting groove 401d. The No. 1 clamping arm 300 and the No. 2 clamping arm 400 are in a horizontal state, and the No. 1 clamping arm 300 and the No. 2 clamping arm 400 are used to block the bracket at the end of the cable drum to perform the lifting operation.

[0041] Specifically, the first turntable 301 is provided with a third locking groove 301e, and the third locking groove 301e and the first arc groove 301b are interconnected; the second turntable 401 is provided with a third limiting groove 401e, and the third limiting groove 401e and the second arc groove 401b are interconnected.

[0042] In this embodiment, the No. 1 clamping arm 300 and the No. 2 clamping arm 400 are inserted into the end of the cable drum, and the No. 1 clamping arm 300 and the No. 2 clamping arm 400 are manually rotated to open, and the lifting rod 101 is pulled up, and the load-bearing shaft 103 enters the No. 3 locking groove 301e and the No. 3 limiting groove 401e. The No. 1 clamping arm 300 and the No. 2 clamping arm 400 are in a horizontal state, and the No. 1 clamping arm 300 and the No. 2 clamping arm 400 are used to block the bracket at the end of the cable drum to perform the lifting operation. Due to the setting of the triangular block 303 and the triangular plate 403, the triangular block 303 and the triangular plate 403 can be clamped in the gap between the brackets at both ends of the cable drum, which can improve the positioning effect during lifting.

[0043] Furthermore, it also includes a lifting mechanism 500, which includes a sliding plate 501 slidably arranged on the suspension rod 101, and a No. 1 cable 502 and a No. 2 cable 503 arranged on the sliding plate 501; in this embodiment, the end of the No. 1 cable 502 is connected to the No. 1 connecting arm 302; the end of the No. 2 cable 503 is connected to the No. 2 connecting arm 402.

[0044] It should be noted that a limit frame 201a is provided on the connecting shaft 201, and a lifting frame 201b is provided on the limit frame 201a. The inner wall of the limit frame 201a and the outer wall of the hanger 102 are slidably connected. In this embodiment, the setting of the lifting frame 201b facilitates lifting the No. 1 clamping arm 300 and the No. 2 clamping arm 400.

[0045] It should be noted that there are many types of cable reels made of different materials, such as cable reels made of iron frames, wooden cable reels, or cable reels composed of iron frames and wood. These cable reels have the same characteristics, that is, holes are provided at their ends, which can be used to pass cables or to set up the cable reels through shafts. The cable reels with wooden ends have no clamping parts for lifting, and after the lifting device enters the center of the cable reel, the operator cannot reach into the center of the cable reel to manually control the first clamping arm 300 and the second clamping arm 400 to open. In view of this, after the No. 1 clamping arm 300 and the No. 2 clamping arm 400 are placed in the center of the cable drum, the suspension rod 101 is continuously controlled to descend, so that the sliding plate 501 contacts the end of the cable drum. After the sliding plate 501 is contacted, it slides on the outer wall of the suspension rod 101, and the No. 1 clamping arm 300 and the No. 2 clamping arm 400 continue to descend until the No. 1 cable 502 and the No. 2 cable 503 on the sliding plate 501 are straightened. After straightening, due to the descent of the suspension rod 101, the load-bearing shaft 103 slides into the No. 1 arc groove 301b and the No. 2 arc groove 401b, and the No. 1 clamping arm 300 and the No. 2 clamping arm 40 0, as the lifting rod 101 descends, the first clamping arm 300 and the second clamping arm 400 rotate to a horizontal state, and the bearing shaft 103 moves to the second limiting groove 401d and the second locking groove 301d. At this time, the lifting rod 101 is pulled up, and the bearing shaft 103 will enter the second locking groove 301d and the second limiting groove 401d. When the bearing shaft 103 enters the second locking groove 301d and the second limiting groove 401d, it will drive the horizontally opened first clamping arm 300 and the second clamping arm 400 to rise and lift the cable drum. At this time, due to the triangular Block 303 and triangular plate 403 face the ground, and the surfaces of No. 1 connecting arm 302 and No. 2 connecting arm 402 are flat, which can protect the wooden cable drum and achieve uniform force. After the lifting is completed, the lifting frame 201b can be lifted to make the load-bearing shaft 103 and the connecting shaft 201 close to each other, and then the load-bearing shaft 103 slides into the No. 1 arc groove 301b and the No. 2 arc groove 401b, and the No. 1 clamping arm 300 and the No. 2 clamping arm 400 are reset under the action of gravity, which facilitates the separation between the sling and the cable drum and avoids the problem of inability to operate due to small space.

[0046] The rest of the structure is the same as that of Example 1.

[0047] Example 3, reference Figure 1 to Figure 9, which is the third embodiment of the present invention. Different from the previous embodiment, the first rotating disk 301 is provided with a first extrusion groove 301c-1, which is connected to the first locking groove 301c; the second rotating disk 401 is provided with a second extrusion groove 401c-1, which is connected to the first limiting groove 401c. In this embodiment, due to the arrangement of the first extrusion groove 301c-1 and the second extrusion groove 401c-1, when the bearing shaft 103 is located at the first When lifting operations are performed in the locking groove 301c and the No. 1 limit groove 401c, the load-bearing shaft 103 has a tendency to slide into the No. 1 extrusion groove 301c-1 and the No. 2 extrusion groove 401c-1. When the load-bearing shaft 103 slides into the No. 1 extrusion groove 301c-1 and the No. 2 extrusion groove 401c-1, the No. 1 clamping arm 300 and the No. 2 clamping arm 400 will be able to perform clamping operations, and as the weight of the lifted object increases, the clamping force will also increase, further improving the stability during lifting.

[0048] Specifically, the connection mechanism 200 further includes a hook 202 rotatably disposed on the connection shaft 201 , and a movable groove 202 a is disposed on the hook 202 ; in this embodiment, an opening 202 b is disposed on the hook 202 .

[0049] Preferably, the first turntable 301 is provided with a first unlocking groove 301f, and the first unlocking groove 301f and the first arc groove 301b are connected to each other; the second turntable 401 is provided with a second unlocking groove 401f, and the second unlocking groove 401f and the second arc groove 401b are connected to each other.

[0050] When the hook 202 is hung on the outside of the load-bearing shaft 103, the load-bearing shaft 103 can slide in the movable groove 202a. When the load-bearing shaft 103 is located in the No. 1 locking groove 301c and the No. 1 limiting groove 401c, since the hook 202 limits the maximum sliding distance of the load-bearing shaft 103, the load-bearing shaft 103 will not slide into the No. 1 extrusion groove 301c-1 and the No. 2 extrusion groove 401c-1. At this time, the load can be borne by the hook 202, and due to the setting of the movable groove 202a, the load-bearing shaft 103 can slide into the No. 1 arc groove 301b and the No. 2 arc groove 401b.

[0051] When the load-bearing shaft 103 needs to be able to enter the No. 1 extrusion groove 301c-1 and the No. 2 extrusion groove 401c-1, first rotate the No. 1 clamping arm 300 and the No. 2 clamping arm 400 to allow the load-bearing shaft 103 to slide into the No. 1 unlocking groove 301f and the No. 2 unlocking groove 401f. At this time, the hook 202 can be rotated to disengage the hook 202 and the load-bearing shaft 103 through the opening 202b on the hook 202. At this time, the restriction of the hook 202 on the movement position of the load-bearing shaft 103 is lost. When the load-bearing shaft 103 is located in the No. 1 locking groove 301c and the No. 1 limiting groove 401c for hoisting, the load-bearing shaft 103 will slide into the No. 1 extrusion groove 301c-1 and the No. 2 extrusion groove 401c-1, so that the No. 1 clamping arm 300 and the No. 2 clamping arm 400 are clamped.

[0052] The rest of the structure is the same as that of Example 2.

[0053] Hoisting method 1: Refer to Figure 7 When facing a cable drum made of an iron frame, the No. 1 clamping arm 300 and the No. 2 clamping arm 400 can be used to clamp the iron frame for lifting operations, and according to the strength of the iron frame, it can be selected whether to release the connection between the hook 202 and the load-bearing shaft 103, and control whether the No. 1 clamping arm 300 and the No. 2 clamping arm 400 can be clamped during lifting.

[0054] Lifting method 2: Refer to Figure 8 When facing a cable drum made of iron frames, when there is a certain gap between the iron frames and the user can manually control the rotation of the No. 1 clamping arm 300 and the No. 2 clamping arm 400, the No. 1 clamping arm 300 and the No. 2 clamping arm 400 can be rotated to a horizontally unfolded state for hoisting, and positioned by the triangular block 303 and the triangular plate 403 to increase the hoisting stability.

[0055] Lifting method three: refer to Fig. 9 When facing a wooden cable reel, or the hole at the end of the cable reel is small and the user cannot manually control the rotation of the No. 1 clamping arm 300 and the No. 2 clamping arm 400, the lifting mechanism 500 is used to control the No. 1 clamping arm 300 and the No. 2 clamping arm 400 to rotate to a horizontally unfolded state for lifting, which can protect the wooden cable reel and facilitate the separation of the lifting device and the cable reel.
