Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of anti-vibration hammers, and more particularly to a self-locking anti-falling anti-vibration hammer. BACKGROUND

[0002] Anti-vibration hammers are used to reduce the vibration of wires caused by wind. High-voltage overhead lines have high poles and large spans, and when the wires are subjected to wind, they will vibrate. When the wires vibrate, the working conditions of the wire suspension are the most unfavorable. Due to repeated vibrations, the wires will be subjected to fatigue damage due to periodic bending. By installing an anti-vibration hammer on the wire, the wind-induced vibration can be suppressed or reduced. Currently, when installing an anti-vibration hammer, it is necessary to consider whether the anti-vibration hammer will come loose or even slide off. When the anti-vibration hammer comes loose and slides on the surface of the cable, it will lose its original anti-vibration ability, and when it slides off due to disengagement from the cable, it will increase the safety risk. Therefore, when installing an anti-vibration hammer, a threaded fastening or pre-twisted wire wrapping method is used to avoid the above-mentioned situations, but this method cannot completely prevent the anti-vibration hammer from coming loose and sliding off. When the anti-vibration hammer is used for a long time and rusted or the cable vibrates frequently, the anti-vibration hammer will work under high intensity, and the anti-vibration hammer will still come loose or even slide off.

[0003] According to the anti-abrasion anti-vibration hammer disclosed in Chinese Patent No. CN119891068B, a wire clamp main body is provided with a wire clamp cover plate at the upper end through a hinge pin shaft, and an annular clamping channel is formed between the wire clamp main body and the wire clamp cover plate. The wire clamp main body can tightly wrap the wire in the circumferential direction, and the flexible auxiliary clamping part and the rotating and pressing structure can effectively press the wire passing through the annular clamping channel, thereby eliminating the gap between the wire clamp and the wire.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0018] Referring to the drawings shown in the specification Figures 1-10 As shown in the drawings, the self-locking anti-falling anti-vibration hammer of the embodiment of the present application comprises a wire clamp 1, the inside of the wire clamp 1 is fixedly connected with a steel strand 6, both ends of the steel strand 6 are fixedly connected with a hammer head 2, the inner side of the wire clamp 1 is slidably connected with a fastening clamp 3, the inner side of the wire clamp 1 is sleeved with a cable 9, one side of the fastening clamp 3 is fixedly connected with a limiting sliding block 4, the limiting sliding block 4 is arranged in a “T” shape, the limiting sliding block 4 is slidably connected to the inner side of the wire clamp 1, the inside of the limiting sliding block 4 is slidably connected with a positioning piece 5, the positioning piece 5 is arranged in an arc shape, a plurality of positioning holes are formed in the inside of the wire clamp 1, the positioning piece 5 is inserted into the positioning holes, one end of the positioning piece 5 is fixedly connected with an elastic sheet 7, the elastic sheet 7 is of an elastic structure, the elastic sheet 7 is fixedly connected to the inside of the limiting sliding block 4, one side of the positioning piece 5 is fixedly connected with a push handle 8, the push handle 8 is slidably connected to the inside of the limiting sliding block 4, both sides of the wire clamp 1 and the fastening clamp 3 are provided with auxiliary fixing assemblies, the inner side of the auxiliary fixing assembly is provided with a self-locking assembly.

[0019] It should be noted that, when the anti-vibration hammer is installed, the wire clamp 1 is hung on the outer side of the cable 9, and the fastening clamp 3 is pushed upward, so that the fastening clamp 3 is displaced upward and in contact with the cable 9, while the positioning piece 5 is displaced upward along with the limiting sliding block 4, and the arc-shaped contour at the top of the positioning piece 5 is in contact with the positioning hole of the wire clamp 1, and under the limiting of the positioning hole, the positioning piece 5 slides to the inside of the limiting sliding block 4, while the elastic sheet 7 is compressed, and when the fastening clamp 3 stops moving, the positioning piece 5 is inserted into the corresponding positioning hole under the stretching action of the elastic sheet 7, so that the fastening clamp 3 is in contact with the cable 9 to achieve installation. Through the arrangement of the positioning piece 5 and the elastic sheet 7, the anti-vibration hammer can be fixed only by pushing the fastening clamp 3 upward when the anti-vibration hammer is installed. This fixing method is pre-fixing, which can keep the anti-vibration hammer in a limited position, facilitate the unfolding of the auxiliary fixing assembly and the self-locking assembly, and replace the fixing method of nut fixing and pre-twisted wire winding in the prior art to improve the convenience of fixing the anti-vibration hammer, and the installation personnel can install without the aid of other tools. At the same time, when the anti-vibration hammer needs to be disassembled, the two positioning pieces 5 are pushed into the inside of the limiting sliding block 4 by the two push handles 8, so that the fastening clamp 3 slides downward away from the cable 9. The same simple disassembly method can facilitate the subsequent maintenance and replacement of the anti-vibration hammer by the installation personnel.

[0020] When the cable 9 vibrates, the hammer head 2 moves up and down, the steel wire 6 generates internal friction due to inertia, and combines with air damping to consume vibration energy, thereby reducing the vibration of the cable 9.

[0021] Further, the auxiliary fixing assembly comprises fixing supports 10 fixedly connected on both sides of the wire clamp 1, the inner side of each fixing support 10 is slidably connected with a connecting rod 11, through holes are formed in the two sides of the connecting rod 11, the connecting rod 11 can slide in the inner side of the fixing support 10 through the through holes, one end of the connecting rod 11 is hingedly connected with an upper clamp sleeve 14, the end of the connecting rod 11 away from the upper clamp sleeve 14 is provided with an arc-shaped end piece 13, one end of each fixing support 10 is fixedly connected with a limiting piece 12, the limiting piece 12 is arranged in abutment with the connecting rod 11, the connecting rod 11 is in an inclined state towards the upper clamp sleeve 14 by abutting and limiting the connecting rod 11 by the limiting piece 12, both sides of the upper clamp sleeve 14 are fixedly connected with connecting sleeve shells 15, both sides of the fastening clamp 3 are fixedly connected with connecting sleeve cylinders 16, the inner side of each connecting sleeve cylinder 16 is slidably connected with a connecting inner rod 17, one end of the connecting inner rod 17 is fixedly connected with a lower clamp sleeve 18, the inner side contour of the upper clamp sleeve 14 and the lower clamp sleeve 18 is combined into a circle, and the diameter of the circle is consistent with the cable 9, both sides of the lower clamp sleeve 18 are fixedly connected with connecting plug plates 19, the connecting plug plates 19 are plugged into the inner side of the connecting sleeve shells 15, the top of the wire clamp 1 is fixedly connected with a limiting frame 20, the outer side of the limiting frame 20 is slidably connected with a stop piece 21, the side of the wire clamp 1 away from the limiting frame 20 is rotatably connected with a double-headed stud 22, the stop piece 21 is arranged in threaded connection with the double-headed stud 22.

[0022] It should be noted that, when the wire clamp 1 is hung on the outer side of the cable 9, the upper clamp sleeves 14 on both sides of the wire clamp 1 can simultaneously contact the cable 9, when the fastening clamp 3 is pushed upward to realize the installation and fixation of the damping hammer, the connecting inner rod 17 is slid out of the inner side of the connecting sleeve cylinder 16 by pulling the lower clamp sleeve 18, until the lower clamp sleeve 18 corresponds to the upper clamp sleeve 14, and the connecting plug plate 19 is inserted into the inner side of the connecting sleeve shell 15 in the process of the upward movement of the fastening clamp 3, so as to complete the connection of the upper clamp sleeve 14 and the lower clamp sleeve 18, and the lower clamp sleeve 18 can contact the cable 9.

[0023] At this time, the anti-vibration hammer can be further fixed. Since only the pre-fixing of the anti-vibration hammer is completed at this time, the upper clamp sleeve 14 and the lower clamp sleeve 18 can still slide outside the cable 9. By pulling the upper clamp sleeve 14 away from the wire clamp 1, the lower clamp sleeve 18 is simultaneously displaced outside the cable 9. Under the limiting of the limiting piece 12, the connecting rod 11 is in an inclined state. Under the limiting of the connecting rod 11 and the connecting rod 11, the connecting rod 11 is in a sliding state of displacement to the right and down when sliding. Thus, when the upper clamp sleeve 14 slides away from the wire clamp 1, the limiting sliding block 4 will be gradually lowered synchronously, thereby being in close contact with the cable 9. In this way, the friction between the upper clamp sleeve 14 and the cable 9 can be increased, the pressure of the upper clamp sleeve 14 on the cable 9 can be improved, and the firmness of the fixation of the anti-vibration hammer can be further improved. At the same time, by rotating the double-headed stud 22, the two retaining pieces 21 are away from each other and are in contact with the arc-shaped end piece 13 on both sides. The retaining piece 21 limits the displacement of the connecting rod 11 in the opposite direction to prevent the upper clamp sleeve 14 from loosening due to the reverse displacement of the connecting rod 11. In this way, the upper clamp sleeve 14 can be kept in close contact with the cable 9 to avoid loosening due to gaps.

[0024] In summary: The limiting piece 12 limits the connecting rod 11, and the connecting rod 11 applies pressure to the upper clamp sleeve 14 to keep the upper clamp sleeve 14 under pressure on the cable 9. The retaining piece 21 blocks the displacement of the connecting rod 11 to achieve multiple limiting. In this way, through the fixed cooperation of the auxiliary fixing assembly on both sides and the fastening clamp 3, the loosening phenomenon caused by rust and corrosion after long-term use of the anti-vibration hammer can be avoided, and the risk of falling of the anti-vibration hammer can be eliminated.

[0025] Further, the wire clamp 1 is internally connected with a top block 23. The bottom of the top block 23 is fixedly connected with a fastener 24. The fastener 24 is slidably connected in the interior of the wire clamp 1. The fastener 24 is made of rubber. The bottom of the fastener 24 is arc-shaped and provided with anti-slip protrusions.

[0026] It should be noted that, wherein, in the connecting rod 11 drive upper sleeve 14 to the right down displacement, the arc-shaped end piece 13 synchronous in the top of the top block 23 top down displacement, so that the arc-shaped end piece 13 on the top block 23 to exert pressure, make the top block 23 drive fastener 24 gradually down, in turn make fastener 24 from the inside of the wire clamp 1 and cable 9 contact, under the limit of the arc-shaped end piece 13, fastener 24 will be in close contact with cable 9, thereby reducing the gap between the wire clamp 1, fastening clamp 3 and cable 9, in turn ensure that the cable 9 and wire clamp 1, fastening clamp 3 keep in close contact state, at the same time, the cable 9 and fastening clamp 3 in close contact, because the lower sleeve 18 and the inner side of the fastening clamp 3 are in the same horizontal line, so that the cable 9 is in close contact with the lower sleeve 18, and the fastener 24 is made of rubber material, so as to avoid excessive pressure on the cable 9, which can cause damage to the surface of the cable 9, and the protective protrusion at the bottom of the fastener 24 can avoid the phenomenon of sliding of the cable 9 in the inner side of the wire clamp 1 and the fastening clamp 3. In this way, the multiple fixation of the damper on the cable 9 is realized, and the fastening of the damper and the cable 9 is ensured.

[0027] Further, the self-locking assembly comprises a compression plate 25 slidably connected to the inner side of the upper sleeve 14, one side of the compression plate 25 being fixedly connected with a locking piece 26, the locking piece 26 being made of rubber material and having a plurality of cavities inside, so that the locking piece 26 can be compressed, the locking piece 26 being arranged on the inner side of the upper sleeve 14, one side of the compression plate 25 being fixedly connected with a pull rope 27, the pull rope 27 being fixedly connected to one side of the wire clamp 1.

[0028] It should be noted that, wherein, in the connecting rod 11 drive upper sleeve 14 to the right down displacement, the arc-shaped end piece 13 synchronous in the top of the top block 23 top down displacement, so that the arc-shaped end piece 13 on the top block 23 to exert pressure, make the top block 23 drive fastener 24 gradually down, in turn make fastener 24 from the inside of the wire clamp 1 and cable 9 contact, under the limit of the arc-shaped end piece 13, fastener 24 will be in close contact with cable 9, thereby reducing the gap between the wire clamp 1, fastening clamp 3 and cable 9, in turn ensure that the cable 9 and wire clamp 1, fastening clamp 3 keep in close contact state, at the same time, the cable 9 and fastening clamp 3 in close contact, because the lower sleeve 18 and the inner side of the fastening clamp 3 are in the same horizontal line, so that the cable 9 is in close contact with the lower sleeve 18, and the fastener 24 is made of rubber material, so as to avoid excessive pressure on the cable 9, which can cause damage to the surface of the cable 9, and the protective protrusion at the bottom of the fastener 24 can avoid the phenomenon of sliding of the cable 9 in the inner side of the wire clamp 1 and the fastening clamp 3. In this way, the multiple fixation of the damper on the cable 9 is realized, and the fastening of the damper and the cable 9 is ensured.
