[0039] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are 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.

[0040] Combine the following Figures 1 to 4 A detachable rope gripper and a main shaft connection device thereof provided in an embodiment of the utility model are described.

[0041] The present embodiment provides a connecting device for a main shaft 3 of a detachable gripper, comprising: an inner gripper 1, a main shaft 3 and a first connecting pin 4.

[0042] Among them, the inner clamp 1 is provided with a sleeve 2, and a first fixing hole 21 is provided on the outer peripheral side of the sleeve 2; the first end of the main shaft 3 is inserted in the sleeve 2, and a second fixing hole 31 is provided on the outer peripheral side of the main shaft 3 along the first direction, the second fixing hole 31 corresponds to the first fixing hole 21, and there is an angle between the first direction and the axial direction of the main shaft 3; the first connecting pin 4 is respectively adapted to the first fixing hole 21 and the second fixing hole 31, and the first connecting pin 4 passes through the first fixing hole 21 and the second fixing hole 31 in sequence to connect the main shaft 3 to the inner clamp 1.

[0043] It can be known from the above scheme that the utility model sets a first fixing hole 21 on the outer peripheral side of the sleeve 2 of the inner clamp 1, and sets a second fixing hole 31 on the outer peripheral side of the main shaft 3, and connects the main shaft 3 and the sleeve 2 by passing the first connecting pin 4 through the first fixing hole 21 and the second fixing hole 31. Since there is an angle between the first direction and the axial direction of the main shaft 3, the main shaft 3 can be prevented from axially moving in the sleeve 2, and the main shaft 3 can be prevented from rotating in the sleeve 2, thereby ensuring the reliability of the connection between the main shaft 3 and the inner clamp 1 and improving the safety of equipment operation.

[0044] As mentioned above, a balance wheel 7 is disposed at the second end of the main shaft 3 .

[0045] In some embodiments, the second fixing hole 31 passes through the main shaft 3 along a first direction, and the first direction is perpendicular to the axial direction of the main shaft 3. That is, the first connecting pin 4 passes through the first fixing hole 21 and the second fixing hole 31 in sequence along the axial direction perpendicular to the main shaft 3, effectively preventing the main shaft 3 from moving and rotating along the axial direction. Figure 1As shown, a pair of first fixing holes 21 are respectively located on the sleeve 2 at both ends of the second fixing hole 31, and threads can be set at both ends of the first connecting pin 4. After the first connecting pin 4 is passed through the first fixing hole 21 and the second fixing hole 31, nuts are respectively used to be threadedly connected to the two ends of the first connecting pin 4 to fix the main shaft 3 and the sleeve 2.

[0046] Furthermore, at least two second fixing holes 31 may be provided on the main shaft 3. For example, two second fixing holes 31 are cross-shaped and spaced apart on the main shaft 3. Four first fixing holes 21 are provided on the sleeve 2. Two first connecting pins 4 are respectively passed through the two second fixing holes 31 to connect the sleeve 2 to the main shaft 3.

[0047] In this embodiment, a first positioning structure is further provided between the first end of the main shaft 3 and the shaft sleeve 2, and the main shaft 3 and the shaft sleeve 2 are connected via the first positioning structure.

[0048] Specifically, the first positioning structure includes: a first positioning hole 32, a second positioning hole 22 and a second connecting pin 5; the first positioning hole 32 is arranged on the first end face of the main shaft 3, and the first positioning hole 32 extends along the second direction, and the second direction is parallel to the axial direction of the main shaft 3; the second positioning hole 22 is arranged on the sleeve 2, and the second positioning hole 22 corresponds to the first positioning hole 32; the second connecting pin 5 is respectively adapted to the first positioning hole 32 and the second positioning hole 22, and the second connecting pin 5 passes through the first positioning hole 32 and the second positioning hole 22 in sequence to connect the main shaft 3 with the inner clamp 1.

[0049] In this arrangement, the second connecting pin 5 is used to connect the main shaft 3 with the inner clamp 1, thereby providing axial pulling force to the main shaft 3, preventing the main shaft 3 from axially separating from the sleeve 2, and improving the reliability of the connection between the main shaft 3 and the sleeve 2.

[0050] Preferably, at least two first positioning holes 32 are provided, and the first positioning holes 32 are arranged offset from the center of the first end surface of the main shaft 3 to prevent the main shaft 3 from circumferential rotation.

[0051] In some embodiments, a limiting structure is further provided between the outer circumference of the main shaft 3 and the sleeve 2, and the limiting structure includes: a mounting hole 23, a limiting hole and an anti-dropping bolt 6, the mounting hole 23 is provided on the outer circumference of the sleeve 2, the limiting hole is provided on the outer circumference of the main shaft 3, and the limiting hole corresponds to the mounting hole 23; the anti-dropping bolt 6 is connected to the mounting hole 23, and the free end of the anti-dropping bolt 6 extends into the limiting groove 33. In other words, by adding the anti-dropping bolt 6, it can extend into the limiting hole, further preventing the main shaft 3 from moving axially in the sleeve 2, and improving the reliability of the connection between the main shaft 3 and the sleeve 2.

[0052] Preferably, the central axis direction of the mounting hole 23 is perpendicular to the axis direction of the main shaft 3 , that is, the anti-dropping bolt 6 is arranged perpendicular to the main shaft 3 .

[0053] Reference Figure 2 and Figure 3 In some embodiments, a limiting structure is further arranged between the outer peripheral side of the main shaft 3 and the sleeve 2, and the limiting structure includes: a mounting hole 23, a limiting groove 33 and an anti-detachment bolt 6, the mounting hole 23 is arranged on the outer peripheral side of the sleeve 2; the limiting groove 33 is arranged on the outer peripheral side of the main shaft 3, and the limiting groove 33 corresponds to the mounting hole 23; the anti-detachment bolt 6 is connected to the mounting hole 23, and the free end of the anti-detachment bolt 6 extends into the limiting groove 33.

[0054] In this embodiment, the limiting groove 33 is distributed in a ring shape on the outer peripheral side of the main shaft 3, so that the difficulty of assembly can be relatively reduced. It is only necessary to install the anti-detachment bolt 6 from the mounting hole 23 to achieve the free end of the anti-detachment bolt 6 extending into the limiting groove 33, thereby preventing the main shaft 3 from moving axially.

[0055] The embodiment of the utility model further provides a detachable rope gripper, comprising a main body and the above-mentioned detachable rope gripper main shaft 3 connecting device, wherein the inner gripper 1 of the detachable rope gripper main shaft 3 connecting device is installed on the main body.

[0056] like Figure 4 As shown, in this embodiment, a manned hanging rod 8 is also included, one end of which is sleeved on the outer peripheral side of the main shaft 3, and the other end can be used to connect to the hanging car.

[0057] In this way, since the detachable rope gripper is provided with the above-mentioned detachable rope gripper main shaft 3 connecting device, it also has all the advantages of the detachable rope gripper main shaft 3 connecting device, that is, through the setting of the first connecting pin 4, the first fixing hole 21 and the second fixing hole 31, the main shaft 3 is connected to the sleeve 2 of the inner clamp 1, and the main shaft 3 can be prevented from rotating and axially moving; through the first positioning hole 32, the second positioning hole 22 and the second connecting pin 5, axial tension is provided to the main shaft 3 to prevent the axial movement of the main shaft 3; through the limiting structure, the main shaft 3 is further prevented from axially moving in the sleeve 2 of the inner clamp 1, thereby ensuring the reliability and safety of the main shaft 3 connection through the triple protection effect, and reducing the occurrence of safety accidents in cableway operation.
