DETAILED DESCRIPTION

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] See also Figure 1-7 The present invention provides a technical solution: a cable traction device for electric power construction, comprising a cable coil 1, and also comprising:

[0051] A traction device body, the traction device body comprising a traction frame 3 fixedly arranged on the ground, a traction unit 4 arranged on the traction frame 3 for clamping and traction of a cable body 2 of different thicknesses, and a limiting unit 5 arranged on both sides of the traction unit 4 for limiting the lateral position of the cable body 2 when the traction unit 4 clamps and pulls the cable body 2;

[0052] The limiting unit 5 includes two sets of limiting mechanisms 51 for laterally limiting the cable body 2 and an adjusting mechanism 52 for synchronously adjusting the limiting mechanism 51 to adapt when the traction unit 4 clamps the cable body 2 of different thicknesses. The two sets of limiting mechanisms 51 are symmetrically arranged on both sides of the incoming and outgoing lines of the traction unit 4 to limit the cable body 2 at the incoming and outgoing line positions on the traction unit 4.

[0053] The traction unit 4 includes a rotating bearing part 41 disposed on the traction frame 3 for bearing the cable body 2, a pressing part 42 slidably disposed on the traction frame 3 for cooperating with the rotating bearing part 41 to clamp the cable body 2, and a power part 43 disposed on the traction frame 3 for adjusting the height of the pressing part 42 to clamp the cable body 2 of different thicknesses;

[0054] After the cable body 2 is pressed by the pressing part 42, the rotating bearing part 41 drives the cable body 2 to move thereon through its own rotation to achieve the pulling out of the cable body 2;

[0055] In this embodiment, the rotating bearing part 41 is configured as a transmission belt, and the transmission belt is a metal plate that is driven by a chain to rotate and transmit, and friction patterns are provided on the metal plate to increase the friction with the cable body 2 under the pressing action of the pressing part 42, thereby preventing the cable body 2 from slipping during the pressing and traction. It serves as a power source for traction, and the rotation of the chain can be achieved through gears cooperating with the motor.

[0056] At the same time, the pressing portion 42 includes:

[0057] The pressing frame 421 is slidably disposed on the traction frame 3;

[0058] Multiple groups of holding rollers 422 are evenly rotated and arranged on the holding frame 421, and are used to cooperate with the rotating bearing part 41 to realize holding and pulling the cable body 2. The holding rollers 422 are set to be symmetrically concave, so that the cable body 2 is in a symmetrical middle position of the concave during holding and pulling, thereby preventing the cable body 2 from being pulled and offset at the holding rollers 422 and the rotating bearing part 41 during pulling, causing a large pulling friction between the outer surface of the cable body 2 and the holding part 42 and the rotating bearing part 41, causing skin damage;

[0059] In this embodiment, the power unit 43 is configured as a plurality of fixed blocks 431 with threaded holes, which are symmetrically arranged on both sides of the pressing frame 421. The threaded holes of the fixed blocks 431 are threadedly connected with threaded rods 432. A rotating motor 433 is arranged at the lower end of the threaded rod 432. The rotating motor 433 works to drive the threaded rod 432 to rotate, thereby realizing the up and down movement of the fixed blocks 431, so that the pressing frame 421 moves up and down.

[0060] In addition, the limiting mechanism 51 includes:

[0061] Two sets of limiting rollers 511 are symmetrically arranged with the inner concave part of the holding roller 422 as the central axis;

[0062] The synchronous moving member 512 is disposed between the two groups of limiting rollers 511 and is used to drive the two groups of limiting rollers 511 to move synchronously to limit the cable body 2 .

[0063] Meanwhile, the synchronous moving member 512 includes:

[0064] Two sets of sliders 5121 are slidably disposed on the traction frame 3, and are used for the two sets of limiting rollers 511 to rotate thereon respectively;

[0065] Two sets of slide rails 5122 are respectively disposed on both sides of the two sets of sliders 5121 to provide sliding tracks for the sliders 5121;

[0066] The two groups of first racks 5123 are respectively arranged on the two groups of sliders 5121 and are arranged obliquely symmetrically with respect to the symmetry centers of the two groups of sliders 5121. A synchronous gear 5124 is arranged between the two groups of first racks 5123 to drive the first racks 5123 to move synchronously.

[0067] In addition, the adjustment mechanism 52 includes:

[0068] The connecting plate 521 is disposed on the pressing frame 421 and is used to move synchronously with the pressing frame 421 when the adjusting member 423 drives the pressing frame 421 to move up and down;

[0069] The rack and pinion set is disposed between the connecting plate 521 and the slider 5121, and is used to drive the two sets of sliders 5121 to move closer or further away synchronously when the connecting plate 521 moves down / up with the holding frame 421, so as to achieve lateral positioning of the cable body 2;

[0070] Wherein, the rack and pinion gear set comprises:

[0071] A second rack 522 is disposed on a group of the sliders 5121 and extends through the connecting plate 521 . The connecting plate 521 is provided with a through slot 523 for the second rack 522 to pass through.

[0072] A third rack 524 is disposed on the connecting plate 521;

[0073] The adjusting gear 525 is disposed at the connection between the second rack 522 and the third rack 524 and is meshed with the second rack 522 and the third rack 524;

[0074] When the connecting plate 521 moves downward, the third rack 524 will move downward accordingly, and then drive the adjusting gear 525 to rotate, thereby driving the second rack 522 to slide, and through the action of the first rack 5123 and the synchronous gear 5124, the two groups of sliders 5121 will slide toward each other, so that when the pressure roller 422 is pressed down and clamped, the limiting roller 511 is synchronized to limit the cable body 2.

[0075] Among them, an auxiliary unit 6 for protecting the cable body 2 when it is pulled manually is provided at one side of the cable outlet of the traction unit 4;

[0076] The auxiliary unit 6 includes a limiting portion 61 for limiting the cable body 2 of different thicknesses and specifications, and an adjusting portion 62 disposed on the limiting portion 61 for changing the direction of the pulling force when manually pulling.

[0077] In this embodiment, when the cable body 2 is pulled out from the traction unit 4, during manual pulling, due to actual wiring reasons, the manual pulling direction is inconsistent with the connection direction of the cable coil 1 and the traction unit 4, resulting in the cable body 2 receiving the pulling force directly transferred to the traction unit 4, thereby affecting the normal traction work on the traction unit 4.

[0078] Wherein, the limiting portion 61 includes:

[0079] A limit plate 611 is arranged on the outlet side of the cable body 2 pulled out from the pulling unit 4;

[0080] A fixed plate 612 is rotatably disposed on the limiting plate 611, and a connecting port 613 for the cable body 2 to pass through is disposed on the limiting plate 611 and the fixed plate 612;

[0081] The limiting member 614 is disposed between the limiting plate 611 and the fixing plate 612 , and is used to limit the cable body 2 passing through the connecting port 613 .

[0082] Meanwhile, the limiting member 614 includes:

[0083] A plurality of limiting grooves 6141 are evenly arranged on the fixing plate 612;

[0084] A plurality of sleeves 6142 are rotatably disposed in the limiting groove 6141 at a fixed point;

[0085] A plurality of limiting plates 6143 are slidably disposed in the sleeve 6142 , one end of the limiting plate 6143 is rotatably disposed at a fixed point on the limiting plate 611 , and the other end extends into the communication port 613 ;

[0086] The fixing mechanism is disposed between the limiting plate 611 and the fixing plate 612 and is used to fix the rotation position of the fixing plate 612 after the fixing plate 612 is rotated to adjust its position.

[0087] The fixing mechanism includes: fixing holes 6146 evenly arranged on the limiting plate 611 and a fixing rod 6144 slidingly arranged on the fixing plate 612, a fixing sheet 6145 is arranged on the fixing rod 6144, a fixing spring 6147 is sleeved on the fixing rod 6144, one end of the fixing spring 6147 abuts against the fixing sheet 6145, and the other end abuts against the fixing plate 612, wherein, for the stability of the fixing, the fixing rod 614 can be provided in multiple groups, and the multiple groups of the fixing rod 614 extending to one side of the outer end of the fixing plate 612 can be connected by a connecting ring, so that the multiple groups of fixing rods 614 can be simultaneously pulled out and fixed in contact;

[0088] When the fixed disk 612 is rotated to adjust its position, the fixing rod 6144 can be pulled out of the fixing hole 6146, and then the fixing spring 6147 is compressed. After the fixed disk 612 is rotated to adjust its position, the fixing rod 6144 is released, and the fixing spring 6147 allows the fixing rod 6144 to be reset and inserted into the fixing hole 6146 for fixation.

[0089] Wherein, the adjustment unit 62 includes:

[0090] Four groups of support rods 621 are symmetrically arranged on both sides of the limiting plate 611, one end of each of the four groups of support rods 621 is rotatably arranged on the limiting plate 611, and the other end is rotatably arranged with an adjustment block 622;

[0091] Two groups of support plates 623 are symmetrically arranged on both sides of the limiting plate 611, and are used for the adjusting block 622 to slide thereon. The support plates 623 are provided with limiting sliding grooves 624 for the adjusting block 622 to slide.

[0092] In actual use, the support plate 623 can be fixed on the ground by itself, or can be fixed on the traction unit 4 by a connecting plate, bolts, etc.;

[0093] Multiple groups of support springs 625 are arranged at the upper and lower ends of the adjustment block 622 in the limiting slide groove 624. One end of the support spring 625 abuts against the adjustment block 622, and the other end abuts against a fixing plate 626. The fixing plate 626 is fixedly arranged in the limiting slide groove 624;

[0094] When the cable body 2 is pulled out from the traction unit 4, the cable body 2 can be manually passed through the connecting port 613, and then the fixing disk 612 can be rotated. At this time, the position of the sleeve 6142 is changed, and the limiting plate 6143 will slide in the sleeve 6142 and change its angle at the same time, so that the angles of multiple limiting plates 6143 can be adjusted according to cable bodies 2 of different thicknesses, so that the limiting space formed by the multiple limiting plates 6143 is slightly larger than the size of the cable body 2, and then the traction operation is continued by manually grasping the end of the cable body 2. When the traction cable is long and the traction direction needs to be changed, resulting in a change in the traction direction of the cable body 2, the traction direction of the cable body 2 is changed. The changed pulling force will act on the limiting part 61 instead of the traction unit 4, which will affect the traction operation of the traction unit 4. At the same time, since the cable body 2 is heavy, when the pulling force is large, when the pulling force acts on the limiting part 61, it will pull the limiting plate 611 and the fixed plate 612 to move toward the support plate 623 on one side, which will cause the support rod 621 to rotate, and the adjustment block 622 at its end will slide in the limiting groove 624, thereby compressing the support spring 625, so that the effect of the pulling force is changed, and the support spring 625 is used to buffer and eliminate it, so that the pulling force on one side is shared by the upper and lower sides of the support plates 623 on both sides, thereby improving the stability of the entire traction operation.

[0095] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
