DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0035] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0036] like Figure 1-Figure 5As shown, it is a structural diagram of a cable crimping device for power transmission line construction provided by an embodiment of the present invention, comprising a bottom box 1, a transverse rotating shaft 2, a placement roller 3, an anti-reversal component, a support plate 12, a clamping component and a quick-release component, wherein the transverse rotating shaft 2 is rotatably mounted on the bottom box 1; the placement roller 3 is fixedly mounted in the middle of the transverse rotating shaft 2, and the placement roller 3 rotates synchronously with the transverse rotating shaft 2 to adjust its own position; the anti-reversal component is arranged in the shell 7 at the side end of the bottom box 1, and is used to control the rotation angle of the transverse rotating shaft 2 in real time; the support plate 12 is symmetrically mounted on the top of the bottom box 1, and a through hole 17 is opened on the support plate 12; the clamping component is rotatably mounted on the support plate 12, and the movable end of the clamping component is slidably connected to the inner side of the support plate 12; the quick-release component is mounted on the movable plate 14 of the clamping component, and rises and falls synchronously with it.

[0037] In one example of the present invention, the cable is pre-passed through a through hole 17 formed on a support plate 12, and the position of the placement slot 5 is adjusted while the placement roller 3 is rotated to facilitate placement of the cable. The clamping assembly is driven to move by an external drive motor 20, and the clamping strip 21 cooperates with the placement roller 3 to crimp the cable.

[0038] like Figure 1 and Figure 2 As shown, as a preferred embodiment of the present invention, the side of the placement roller 3 is provided with a plurality of flat sections 4, and each section 4 is provided with a placement slot 5;

[0039] The size of the card slot 5 changes linearly in a clockwise or counterclockwise direction.

[0040] In one embodiment of the present invention, the transverse rotating shaft 2 is driven by an external control disk 6 so as to drive the placement roller 3 to rotate synchronously, and the position of the placement roller 3 is adjusted according to the diameter of the cable extending from the side of the support plate 12;

[0041] When in use, the control disk 6 is rotated in advance according to the size of the cable, and the control disk 6 drives the horizontal rotating shaft 2 to rotate along the bottom box 1, and the placement roller 3 and the placement slot 5 rotate synchronously therewith, and the cable passes through the through hole 17 and is placed on the placement slot 5.

[0042] like Figure 1 and Figure 3 As shown, as another preferred embodiment of the present invention, the anti-reversal assembly includes a driving ratchet 8, a braking pawl 9, a leaf spring 10 and a pull rod 11;

[0043] The driving ratchet 8 is fixedly mounted on the end of the transverse rotating shaft 2;

[0044] The side surface of the driving ratchet 8 contacts with a braking pawl 9 installed in the housing 7, and the braking pawl 9 abuts against a leaf spring 10 fixedly arranged in the housing 7;

[0045] The pull rod 11 is slidably mounted on the housing 7 , and one end of the pull rod 11 is hinged to the brake pawl 9 .

[0046] In one example of the present invention, when the transverse rotating shaft 2 rotates along the bottom box 1, the driving ratchet 8 rotates synchronously with the transverse rotating shaft 2. The braking pawl 9 and the leaf spring 10 are provided to prevent the driving ratchet 8 from rotating in the opposite direction during rotation. When it is necessary to unlock the driving ratchet 8, the pull rod 11 is pulled outward along the outer shell 7. The pull rod 11 pulls the braking pawl 9 to deflect along the outer shell 7, and the leaf spring 10 is elastically deformed under the force.

[0047] like Figure 1 and Figure 4 As shown, as another preferred embodiment of the present invention, the clamping assembly includes a driving member 13, a movable plate 14, a limiting block 15 and a limiting groove 16;

[0048] The driving member 13 is rotatably mounted on the supporting plate 12, and a movable plate 14 is mounted on the driving member 13;

[0049] Wherein, limiting blocks 15 are fixedly installed on both sides of the movable plate 14 , and the limiting blocks 15 are slidably connected to limiting grooves 16 opened on the inner side of the supporting plate 12 .

[0050] In one example of the present invention, when the driving member 13 rotates along the support plate 12, the driving member 13 pushes the movable plate 14 to move horizontally in the height direction, and the limit blocks 15 installed on both sides of the movable plate 14 slide along the limit grooves 16 opened on the inner side of the support plate 12 to ensure that the movable plate 14 is stably lifted and lowered.

[0051] like Figure 1 and Figure 5 As shown, as another preferred embodiment of the present invention, pulleys 18 are installed at the bottom ends of the driving members 13 on both sides, and adjacent pulleys 18 are connected through a synchronous belt 19;

[0052] The driving member 13 on one side is connected to the shaft end of the driving motor 20 externally mounted on the support plate 12 via a coupling.

[0053] In one example of the present invention, the driving motor 20 can drive the driving member 13 on one side to rotate along the support plate 12 when working, and the pulley 18 on this side rotates synchronously therewith. The pulley 18 also drives the driving member 13 on the other side to rotate synchronously along the support plate 12 through the set synchronous belt 19, and finally makes the driving members 13 on both sides rotate in the same direction.

[0054] like Figure 1 As shown, as another preferred embodiment of the present invention, the quick release assembly includes a pressing strip 21, a threaded rod 22 and a nut 23;

[0055] The pressing strip 21 is arranged at the bottom of the movable plate 14, and a slot is provided at the bottom of the pressing strip 21;

[0056] A pair of threaded rods 22 are installed on the upper surface of the pressing strip 21 . The threaded rods 22 penetrate the movable plate 14 and are locked by external nuts 23 .

[0057] In one example of the present invention, when the movable plate 14 is raised or lowered, the clamping strip 21 is raised or lowered synchronously therewith, and the clamping strip 21 cooperates with the placement slot 5 to realize the crimping of the cable. When a different clamping strip 21 needs to be replaced, the clamping strip 21 can be released by removing the nut 23 with a wrench. After replacing the appropriate clamping strip 21, the clamping strip 21 is reinstalled on the bottom of the movable plate 14 using the nut 23.

[0058] In summary, the control disk 6 is rotated in advance according to the size of the cable, and the control disk 6 drives the transverse shaft 2 to rotate along the bottom box 1, and the placement roller 3 and the placement slot 5 rotate synchronously therewith. When the transverse shaft 2 rotates along the bottom box 1, the driving ratchet 8 rotates synchronously with the transverse shaft 2. The provided braking pawl 9 and leaf spring 10 can prevent the driving ratchet 8 from rotating in the opposite direction during rotation. When it is necessary to release the lock of the driving ratchet 8, the pull rod 11 is pulled outward along the outer shell 7. The pull rod 11 pulls the braking pawl 9 to deflect along the outer shell 7, and the leaf spring 10 is elastically deformed by the force. The cable passes through the through hole 17 and is placed on the placement slot 5. The driving motor When working, 20 can drive the driving member 13 on one side to rotate along the support plate 12, and the pulley 18 on this side rotates synchronously therewith. The pulley 18 also drives the driving member 13 on the other side to rotate synchronously along the support plate 12 through the arranged synchronous belt 19, so that the driving members 13 on both sides finally rotate in the same direction. When the driving member 13 rotates along the support plate 12, the driving member 13 pushes the movable plate 14 to move horizontally in the height direction, and the limit blocks 15 installed on both sides of the movable plate 14 slide along the limit grooves 16 opened on the inner side of the support plate 12 to ensure that the movable plate 14 is stably lifted and lowered, and the clamping strip 21 is lifted and lowered synchronously therewith, and the clamping strip 21 cooperates with the arranged placement slot 5 to realize the crimping of the cable.
