DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0036] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0037] like Fig.10As shown in the figure, after the traction rope breaks, the wire rope in tension is split into two parts. Because the tension disappears at the break, the wire rope loses tension on one side at the break, causing unbalanced force. At this time, the wire rope will have an instantaneous acceleration toward both sides of the cross section, and at the same time, due to its own gravity, there will be a downward acceleration. As time goes by, the speed at which the wire rope slides out along the pulley to the side of the span will become faster and faster in the direction of acceleration, and finally the wire in the span together with the walking board will whip. At this time, the spanning frame in the span will bear the gravity impulse and a large lateral tension impulse at the same time, and the spanning frame will not be able to effectively protect important facilities.

[0038] like Fig.11 As shown in the figure, point A is the location of the wire-breaking clamping device installed on the tower behind the wire break, and point B is the location of the center of gravity of the wire in the span section. The walkway and wire pulled by the wire rope fall freely under the action of gravity G, thereby driving the wire break to run back. At this time, the wire rope can be fixed and clamped by the wire-breaking clamping device set at point A to prevent the walkway and wire pulled by the wire rope from falling and provide certain protection for them.

[0039] Reference Figure 1-Figure 9 As shown, a wire rope breaking clamping device for power transmission line traction includes:

[0040] A fixing frame 1 is installed on the tower, wherein a plurality of the broken wire clamping devices may be arranged at a certain interval;

[0041] The first wire-breaking clamping assembly 2 is slidably arranged in the fixing frame 1. When the wire rope passes through the first wire-breaking clamping assembly 2, the first wire-breaking clamping assembly 2 will not be triggered in the case of normal routing. Only when the wire is broken, the wire rope will move back. At this time, the wire rope will activate the first wire-breaking clamping assembly 2 to fix and clamp the wire rope;

[0042] The damper 4 is arranged at one side of the first wire-breaking clamping assembly 2, and is used to support the first wire-breaking clamping assembly 2. Since the rebound force is relatively large when the wire rope rebounds, after the first wire-breaking clamping assembly 2 fixes and clamps the wire rope, the wire rope will also drive the first wire-breaking clamping assembly 2 to move backward, and then the damper 4 is used to support it in the reverse direction to reduce the force;

[0043] The second wire-breaking clamping assembly 5 is arranged at the other side of the first wire-breaking clamping assembly 2, and is used to clamp the broken wire. When the first wire-breaking clamping assembly 2 moves, the second wire-breaking clamping assembly 5 is activated to fix and clamp the wire rope again, and limit the movement of the first wire-breaking clamping assembly 2, so as to protect the damper 4;

[0044] The connecting rod 6 is arranged on the first broken wire clamping assembly 2 and is used for driving the second broken wire clamping assembly 5 .

[0045] In one embodiment, the first broken wire clamping assembly 2 includes a wire-drawing roller 21 rotatably arranged on a fixed frame 1, a pressure roller 22 for clamping the broken wire is movably arranged on the upper end of the wire-drawing roller 21, and a driving assembly 23 for pushing the pressure roller 22 is arranged on one side of the wire-drawing roller 21. The wire rope passes through the wire-drawing roller 21, and the pressure roller 22 is located directly above the wire-drawing roller 21 and has a certain gap, which is sufficient for routing. During normal routing, that is, moving from the damper 4 to the direction of the second broken wire clamping assembly 5, it will not start the first broken wire clamping assembly 2. Only when the wire breaks and the wire rope runs back, the wire rope will drive the wire-drawing roller 21 to rotate, thereby starting the driving assembly 23, allowing the pressure roller 22 to move down and fix the wire rope.

[0046] In one embodiment, support plates 211 are provided at both ends of the wire-string roller 21, a movable groove is provided on the support plate 211, a slide bar 212 is provided in the movable groove, and limiting sliders 221 sleeved on the slide bar 212 are provided at both ends of the pressure roller 22, and a limiting spring 213 sleeved on the slide bar 212 is provided between the limiting slider 221 and the movable groove; in the initial state, the pressure roller 22 will form a certain distance with the wire-string roller 21 under the elastic force of the limiting spring 213, so that the wire rope can pass through, and when the wire is broken, the driving component 23 will push the pressure roller 22 downward, so that the pressure roller 22 can fix and clamp the wire rope.

[0047] In one embodiment, the driving assembly 23 includes a guide plate 231 fixed on the fixed frame 1, a ruler 232 is slidably arranged in the guide plate 231, wherein the ruler 232 itself has a certain friction force with the guide plate 231, so that the ruler 232 will not easily fall from the guide plate 231, a crossbeam 233 is fixedly arranged at the top of the ruler 232, a push plate 234 for pushing the pressure roller 22 is arranged on the crossbeam 233, a baffle 11 for inserting on the push plate 234 is fixedly arranged on the top of the fixed frame 1, a fixed plate 235 is fixedly arranged on the side wall of the guide plate 231, a driving gear 236 is rotatably arranged on the fixed plate 235, the driving gear 236 is meshed with the ruler 232, and the driving gear 236 is connected to the wire racking roller 21;

[0048] During normal routing, the wire rope will also drive the wire roller 21 to rotate, and the wire roller 21 will drive the driving gear 236 to rotate, and the driving gear 236 will push the ruler 232 upward until the push plate 234 is embedded in the baffle 11 to form a card connection, thereby fixing the entire first wire breaking clamping assembly 2; and when the wire breaks, the wire rope will run, which will drive the wire roller 21 to reverse, and the wire roller 21 will drive the driving gear 236 to reverse, and the driving gear 236 will drive the push plate 234 to move downward through the ruler 232, so that the push plate 234 pushes the pressure roller 22 downward, thereby allowing the pressure roller 22 to fix and clamp the wire rope.

[0049] In one embodiment, the driving gear 236 includes a toothed disc 2361 connected to the wire-hanging roller 21, and movable teeth 2362 meshing with the ruler 232 are distributed in a circumferential array on the toothed disc 2361. A receiving groove for receiving the movable teeth 2362 is also provided on the toothed disc 2361. A fixed shaft 2363 is provided at the bottom of the movable teeth 2362. The movable teeth 2362 are rotatably connected to the toothed disc 2361 through the fixed shaft 2363. A guide rod 2364 inserted in the receiving groove is provided at the bottom of the movable teeth 2362. A return spring 2365 sleeved on the guide rod 2364 is provided between the movable teeth 2362 and the receiving groove.

[0050] During normal routing, the wire rope will drive the driving gear 236 to rotate through the wire roller 21, and when the push plate 234 moves to the top, it will engage with the baffle 11 to fix the ruler 232. At this time, the ruler 232 cannot continue to move upward, and when the driving gear 236 rotates, the movable tooth 2362 will be blocked by the ruler 232, so that the movable tooth 2362 will flip toward the direction of the storage slot and compress the reset spring 2365, thereby satisfying the continuous rotation of the driving gear 236. After the movable tooth 2362 passes over the ruler 232, the movable tooth 2362 will bounce upward under the elastic force of the reset spring 2365, and the other end of the movable tooth 2362 is stuck on the toothed disc 2361. When the driving gear 236 reverses, it will directly drive the ruler 232 to move downward.

[0051] In one embodiment, a backing plate 3 is provided on one side of the fixing frame 1, and the damper 4 includes a fixing sleeve 41 fixed on the backing plate 3, and the fixing sleeve 41 is divided into a first cavity 411 and a second cavity 412, wherein the first cavity 411 contains a damping medium, and the second cavity 412 can be a cavity, and a pressure rod 42 connected to the first broken wire clamping assembly 2 is inserted in the fixing sleeve 41, and a first piston 43 located in the first cavity 411 is sleeved on the pressure rod 42, and a through hole is opened on the first piston 43, and a second piston 44 located in the second cavity 412 is provided at one end of the pressure rod 42 away from the first broken wire clamping assembly 2, and a damping spring 45 sleeved on the pressure rod 42 is provided between the fixing sleeve 41 and the first broken wire clamping assembly 2.

[0052] In one embodiment, the second wire-breaking clamping assembly 5 comprises an L-shaped frame 51, the top end of the L-shaped frame 51 is fixed to the fixed frame 1 through a first mounting frame 511, the L-shaped frame 51 is rotatably provided with a driving plate 52 through a first movable shaft 521, the top end of the driving plate 52 is rotatably provided with a pull rod 53 through a second movable shaft 522, the end of the pull rod 53 away from the driving plate 52 is inserted on the L-shaped frame 51, the pull rod 53 is connected to the first wire-breaking clamping assembly 2 through a connecting rod 6, and a pressing plate 54 is rotatably provided on the driving plate 52 through a third movable shaft 523, a bottom plate 55 fixed to the L-shaped frame 51 is provided at the bottom of the pressing plate 54, and the bottom plate 55 is fixed to the fixed frame 1 through a second mounting frame 551, wherein the steel wire rope passes through the gap between the bottom plate 55 and the pressing plate 54, and a non-return assembly 56 is further provided on the side of the L-shaped frame 51 away from the pressing plate 54;

[0053] At the beginning, there is a gap between the pressure plate 54 and the bottom plate 55 through which the wire rope can pass. After the wire is broken, the wire rope is first fixed and clamped by the first wire-breaking clamping assembly 2. After the clamping is completed, the force of the wire rope will force the first wire-breaking clamping assembly 2 to continue to move backward to squeeze the damper 4. At this time, the first wire-breaking clamping assembly 2 will pull the pull rod 53 through the connecting rod 6, and the pull rod 53 will drive the driving plate 52 to deflect along the first movable axis 521, thereby driving the pressure plate 54 on the other side to move downward, and clamp and fix the wire rope again. At the same time, after clamping and fixing, the first wire-breaking clamping assembly 2 cannot continue to move backward, thereby forming a certain protective effect on the damper 4.

[0054] In one embodiment, the anti-return assembly 56 includes a ratchet 561 sleeved on the first movable shaft 521, a pawl 562 is provided on one side of the ratchet 561, a first stop bar 563 is provided at the bottom of the pawl 562, a second stop bar 564 is provided at the top of the pawl 562, and a compression spring 565 is provided between the pawl 562 and the second stop bar 564;

[0055] The ratchet 561 is installed on the first movable shaft 521. In this way, when the connecting rod 6 pulls the pull rod 53 to cause the first movable shaft 521 to rotate, the ratchet 561 will be driven to rotate. After the pressure plate 54 fixes and clamps the wire rope, the pressure plate 54 cannot be opened under the action of the ratchet 561 and the pawl 562, thereby ensuring the clamping effect on the wire rope.

[0056] In one embodiment, a frame 20 is sleeved on the surface of the first broken wire clamping assembly 2, a vertical plate 201 is provided on the frame 20, a slide groove is provided on the vertical plate 201, a movable slider is also provided at the bottom of the frame 20, and a slide rail matching the movable slider is provided on the fixed frame 1, a first connecting block 61 sleeved on the L-shaped frame 51 is provided at one end of the connecting rod 6, a pull ring is also provided at the rear end of the L-shaped frame 51, the first connecting block 61 is sleeved on the pull ring and can slide on the pull ring, and a second connecting block 62 located in the slide groove and sliding is provided at the other end of the connecting rod 6;

[0057] After the wire breaks, the first wire-break clamping assembly 2 compresses the damper 4 under the action of the wire rope running back, and at the same time, the connecting rod 6 is pulled through the frame 20, and the connecting rod 6 pulls the pull rod 53 to start the second wire-break clamping assembly 5.

[0058] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
