Description

Technical Field

[0001] The invention relates to the technical field of anti-vibration hammers, in particular to an anti-vibration hammer with a vibration self-locking structure to prevent falling off. Background Art

[0002] The anti-vibration hammer is designed to reduce the vibration of the conductor caused by wind. The pole position of the high-voltage overhead line is high and the span is large. When the conductor is affected by wind, it will vibrate. When the conductor vibrates, the working conditions at the conductor suspension point are most unfavorable. Due to multiple vibrations, the conductor will suffer fatigue damage due to periodic bending. When the overhead line span is greater than 120 meters, an anti-vibration hammer is generally used to prevent vibration.

[0003] When existing power shock-absorbing hammers are installed on cables, they are mostly fixed on the power cables by bolts, that is, the bolts pass through the upper and lower cover plates so that the cover plates wrap the cables. As the cable shakes under the action of wind, when the rust produced by rust between the upper and lower cover plates fixed by the bolts falls off, the gap directly pressed by the cover plates increases. Long-term shaking will cause the bolts to loosen, which will cause the cover plates and the cables to loosen and the cover plates to separate from the cables as the cables shake. Secondly, the cable runs from the insulation of one frame to the insulation of another frame. The positions of the insulation connection points at both ends of the cable in this distance are high, and the position of the middle part is low. Therefore, when the cable shakes, the shaking amplitude of the cable in the middle is larger, and the amplitude of the shock-absorbing hammer that needs to balance the cable vibration is also correspondingly larger. The shock-absorbing hammers are generally arranged in a symmetrical shape, which results in the vibration-absorbing hammers close to the insulation having a lower effect of reducing the vibration of the cable far away from the insulation. Summary of the invention

[0004] The object of the present invention is to provide an anti-vibration hammer with a vibration self-locking structure to prevent falling off, so as to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention aims to provide an anti-vibration hammer with a vibration self-locking structure to prevent falling off, an anti-vibration hammer with a vibration self-locking structure to prevent falling off, comprising an anti-vibration hammer assembly and a fixing ring slidably connected to the anti-vibration hammer assembly, a counterweight elastically connected to the anti-vibration hammer assembly slides on a connecting rod connected between an upper magnet and a lower magnet, the anti-vibration hammer assembly is slidably connected to an auxiliary part, the auxiliary part and the fixing ring above are slidably connected, and the fixing ring is slidably connected to a T-shaped rod;

[0006] The fixing ring is divided into an upper and lower part, which wraps around the cable and fixes the ejection assembly to the fixing piece provided on the inner wall of the fixing ring under the gravity of the T-shaped rod and the anti-vibration hammer assembly, connects the upper and lower fixing rings together, and the ejection assembly squeezes the T-shaped rod to fix the fixing ring and the cable, and the ejection assembly is held against by the limit assembly in the cavity;

[0007] The counterweight block shakes and separates from the upper magnet, and the counterweight block drives the shock-absorbing hammer assembly to move away from the insulation of the connecting cable, so as to reduce the vibration of the cable. The height of the shock-absorbing hammer assembly is reduced and a vibration zone is formed in the direction of movement of the shock-absorbing hammer assembly. The counterweight block pulls the T-shaped rod due to inertia to squeeze the ejection assembly, so that the fixing ring and the cable are firmly fixed.

[0008] In the above scheme, the specific implementation steps are as follows: first, the T-shaped rods on both sides are moved to move toward the inside of the fixing ring so that the upper and lower fixing rings can fit together to wrap the cable, the elastic potential energy of the third spring connecting the T-shaped rods increases, and the upper top ring and the lower top ring fit together, and then the T-shaped rods on both sides are released, and the third spring pulls the T-shaped rods on both sides to move inward and fit with the upper top ring. At this time, under the action of the gravity of the shock-absorbing hammer assembly at the bottom of the T-shaped rod, the T-shaped rod is pulled to squeeze the upper top ring to both sides, and the upper top ring drives the lower top ring to move outward together and connects the upper top ring and the lower top ring together through the fixing piece, thereby realizing the restriction of the upper and lower fixing rings, so that the fixing ring can be put on the cable to prevent it from detaching from the cable.

[0009] When the cable swings up and down with a small amplitude, the counterweight block will attract the upper magnet, and the shock-proof hammer bodies on both sides of the elastic rod will swing up and down. When the cable swings up and down with a larger amplitude, the cable away from the insulation of the cable swings more violently. Therefore, under the action of inertia, the upper magnet breaks away from the attraction of the counterweight block, and the upper magnet slides downward on the connecting rod and drives the first spring to stretch. At the same time, the first spring pulls the shock-proof hammer body on one side to squeeze the second spring, so that the second spring pushes the shock-proof hammer body on the other side to move away from the first spring. When the shock-proof hammer body on the side away from the first spring (the left side, that is, the direction where the cable insulation is located) collides with the end of the elastic rod, the elastic rod can be pushed out to the right, thereby increasing the swing amplitude of the shock-proof hammer body on the right side of the elastic rod, thereby reducing the vibration of the cable.

[0010] At the same time, the upper magnet contacts the lower magnet and lowers the height of the elastic rod, so that the right-side shock-absorbing hammer body will not contact the shaking cable when it swings up and down in the vibration zone. The reduction in the height of the elastic rod will also cause the fixing ring and the T-shaped rod to be subjected to downward pressure. The arc-shaped top plate squeezes the friction block in the cavity of the fixing ring to lock the fixing ring and the cable. The limit assembly clamps the arc-shaped top plate, and the depth of the upper and lower top rings moving toward the fixing part increases, so that the upper and lower fixing rings are firmly fixed, thereby preventing the fixing ring from detaching from the cable and preventing the fixing ring from rotating on the cable.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. In the anti-vibration hammer with a vibration self-locking structure to prevent falling off, the T-shaped rod is provided to form an outward pressure on the upper top rings on both sides, so that the upper top ring and the lower top ring on the same side move together and are inserted into the fixing piece, and the fixing piece just fixes the upper top ring and the lower top ring together, and the upper and lower fixing rings wrap the cable. When the cable shakes violently, the anti-vibration hammer bodies on both sides shake up and down to increase the downward pressure on the T-shaped rod, and the force of the T-shaped rod pushing the upper top ring and the lower top ring to both sides increases, thereby pushing the friction block to lock the cable, and the limit assembly clamps the arc top plate to prevent the upper top ring and the lower top ring from moving in the opposite direction. At this time, the upper top ring and the lower top ring move to an increased depth of the fixing piece, so that the upper top ring and the lower top ring are firmly fixed to prevent the upper and lower fixing rings from detaching from the cable.

[0013] 2. In the anti-vibration hammer with a vibration self-locking structure to prevent falling off, the anti-vibration hammer bodies on both sides can slide on the elastic rod, and the elastic rod is slidably connected to the ring. When the cable shaking amplitude increases, the upper magnet is separated from the attraction of the counterweight block to drive the first spring on the left to lengthen, so that the anti-vibration hammer body on the left slides on the elastic rod, and the second spring pushes the anti-vibration hammer body on the right to move away from the first spring. When the anti-vibration hammer body on the right collides with the end of the elastic rod, the elastic rod will extend a distance to the right to cooperate with the cable with a large shaking amplitude on the right side, thereby reducing the vibration of the cable on the right side.

[0014] 3. In the anti-vibration hammer with a vibration self-locking structure to prevent falling off, when the upper magnet descends and is attracted to the lower magnet, a downward setback will be generated at the moment when the upper magnet and the lower magnet are attracted, so that the vertical rod is compressed downward, and the elastic card that pops out will block the vertical rod to prevent the vertical rod from moving up. At this time, the height of the anti-vibration hammer body is reduced and it shakes in the vibration area formed when it descends, preventing the shaking anti-vibration hammer body from contacting the cable above.

[0029] 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.

[0030] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0031] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0032] like Figure 1 As shown, the device includes an anti-vibration hammer assembly 100 and a fixing ring 203 slidably connected to the anti-vibration hammer assembly 100. The auxiliary part 300 is slidably connected to the anti-vibration hammer assembly 100. When the upper and lower fixing rings 203 are installed on the cable, first, the T-shaped rods 205 on both sides are moved to move them toward the inside of the fixing ring 203, so that the third spring 204 is stretched so that the upper and lower fixing rings 203 can fit each other to wrap the cable. When the fixing ring 203 is fixed on the cable, the T-shaped rod 205 is released, and the T-shaped rod 205 fits with the ejection assemblies 400 on both sides. The weight of the T-shaped rod 205 and the bottom device squeezes the ejection assemblies 400 on both sides, and the lower ejection rings 402 on both sides connect the upper and lower fixing rings 203 together through the ejection assemblies 400.

[0033] When the cable swings up and down with a small amplitude, the counterweight 200 attracts the upper magnet 201, and the shock-proof hammer assembly 100 swings with a small amplitude. At this time, the shock-proof hammer bodies 101 on both sides of the shock-proof hammer assembly 100 are stretched by the second spring 104. When the cable swings violently under the influence of wind, the upper magnet 201 breaks free from the suction of the counterweight 200 and slides downward along the connecting rod gradually approaching the lower magnet 202 at the bottom of the connecting rod.

[0034] Therefore, the specific structure of the anti-vibration hammer assembly 100 is disclosed. Figure 2 and Figure 3As shown, the anti-vibration hammer assembly 100 includes an anti-vibration hammer body 101, an elastic rod 102 and a first spring 103. The first spring 103 fixedly connected to the left anti-vibration hammer body 101 is connected to the counterweight 200. When the counterweight 200 is attracted to the upper magnet 201, the first spring 103 is in a natural state. Therefore, as the upper magnet 201 moves downward, the first spring 103 on the left side will be stretched. The anti-vibration hammer bodies 101 on both sides are sleeved on the elastic rod 102 and slidably connected to the elastic rod 102. The elastic rod 102 is provided with a second Both ends of the spring 104 are fixedly connected to the shock-absorbing hammer body 101, so the elastic potential energy of the stretched first spring 103 increases. Because the upper magnet 201 is affected by gravity and the suction force of the lower magnet 202, and the suction force of the counterweight block 200 on the upper magnet 201 is relatively small at this time, the shock-absorbing hammer body 101 on the left side slides on the elastic rod 102 under the pull of the first spring 103 and pushes the second spring 104 inside the elastic rod 102 to move the shock-absorbing hammer body 101 on the right side away from the first spring 103.

[0035] When the shock-proof hammer body 101 on the right side hits the right end of the elastic rod 102, the elastic rod 102 is subjected to the impact force and the elastic rod 102 is slidably connected to the auxiliary part 300, so the elastic rod 102 will slide to the right for a distance, that is, the elastic rod 102 on the left side of the auxiliary part 300 is shorter than the elastic rod 102 on the right side. The purpose is: because the cable is installed for a long time, the vibration amplitude of the cable close to the insulation of the frame is smaller, and the vibration amplitude of the cable far away from the insulation is larger. Therefore, the shock-proof hammer body 101 on the right side of the auxiliary part 300 swings on the sliding elastic rod 102 and the swing amplitude of the shock-proof hammer body 101 increases with the increase of wind force. The shock-proof hammer body 101 on the right side can produce a movement in the opposite phase to the cable vibration, thereby reducing the vibration of the cable.

[0036] In addition, the cable runs from the insulation of one frame to the insulation of another frame. The insulation positions of the two ends of the cable are high, while the middle part is low. This causes the height of the shock-proof hammer body 101 on the right to be lower than that of the shock-proof hammer body 101 on the left. When the shock-proof hammer body 101 on the right shakes, the upper magnet 201 pulls the first spring 103, and the second spring 104 holds the shock-proof hammer body 101 on the right.

[0037] like Figure 2 , Figure 4 and Figure 5As shown, when the upper magnet 201 drops to the moment of being attracted to the lower magnet 202, a downward jerk will be generated, because the vertical rod 302 fixedly connected to the top of the ring 301 is slidably connected to the fixed ring 203, and a fourth spring 303 is provided between the vertical rod 302 and the fixed ring 203, and the bottom of the fourth spring 303 is against the fixed ring 203, and the top of the fourth spring 303 is against the vertical rod 302. Therefore, when the upper magnet 201 and the lower magnet 202 are attracted, the jerk generated will have a downward pressure, thereby driving the ring 301 and the vertical rod 302 to move downward and compress the fourth spring 303, and the elastic potential energy of the compressed fourth spring 303 increases until the downward pressure of the upper magnet 201 can no longer compress the fourth spring 303.

[0038] In this process, since the elastic card 304 is located in the groove in the connecting tube 305, when the elastic card 304 escapes from the inside of the vertical rod 302, the elastic card 304 will continuously pop up from the top of the vertical rod 302 and the bottom of the elastic card 304 is parallel to the top of the vertical rod 302 after it pops up, and the popped-out elastic card 304 blocks the vertical rod 302 to prevent the vertical rod 302 from moving upward under the elastic action of the fourth spring 303. At this time, the height of the shock-absorbing hammer body 101 is reduced and it shakes in the vibration zone formed when it descends, thereby preventing the shaking shock-absorbing hammer body 101 from contacting the cable above.

[0039] At the same time, the upper magnet 201 contacts the lower magnet 202 and reduces the height of the elastic rod 102, so that the right shock-absorbing hammer body 101 will not contact the shaking cable when it shakes up and down in the vibration zone, and the reduction in the height of the elastic rod 102 will also cause the fixing ring 203 and the T-shaped rod 205 to be subjected to downward pressure, because the frustration generated by the attraction of the upper magnet 201 and the lower magnet 202 will be transmitted to the fixing ring 203 through the fourth spring 303, that is, the squeezing force of the vertical rod 302 on the fourth spring 303 will act in the opposite direction on the fixing ring 203, so that there is downward pressure on the fixing ring 203, and the fixing ring 203 will drive the T-shaped rod 205 to move downward and squeeze the ejection components 400 on both sides of the fixing ring 203. The ejection component 400 pairs of connecting rods and arc-shaped top plates 405 eject the friction block 206 in the cavity of the fixing ring 203, and the cable is locked by the friction block 206, so that the fixing ring 203 and the cable are fixed together to prevent the fixing ring 203 from rotating on the cable.

[0040] Moreover, when the anti-vibration hammer body 101 and the elastic rod 102 on both sides slide downward, there will be a pulling force pulling the T-shaped rod 205 downward. When the anti-vibration hammer body 101 and the elastic rod 102 move upward, the elastic card 304 will hold the vertical rod 302, so the T-shaped rod 205 will also move upward. However, the T-shaped rod 205 will not squeeze the ejection assembly 400.

[0041] As described above, the ejection assembly 400 is used to push the connecting rod and the arc-shaped top plate 405 to squeeze the friction block 206, so the specific structure of the ejection assembly 400 is disclosed, such as Figure 6 and Figure 7 As shown, the ejection assembly 400 includes an upper ejection ring 401 and a lower ejection ring 402. The upper ejection ring 401 and the lower ejection ring 402 will cover the cable when they are matched, and there is still a little gap between the upper ejection ring 401 and the lower ejection ring 402 after covering the cable. The wedge body 404 symmetrically arranged on the upper ejection ring 401 fits with the T-shaped rod 205. When the T-shaped rod 205 moves downward, the upper ejection rings 401 on both sides will be squeezed outward, and grooves are symmetrically provided on both sides of the upper ejection ring 401. The grooves and the protrusions provided on the top of the lower ejection ring 402 cooperate with each other. The purpose of this is: when the T-shaped rod 205 squeezes the wedge body 404 arranged on the inner side of the upper ejection ring 401, the grooves will press the protrusions so that the upper ejection ring 401 moves outward and can simultaneously drive the lower ejection ring 402 to move, thereby squeezing the friction block 206 in the cavity.

[0042] Secondly, because limiting holes are provided on both the upper top ring 401 and the lower top ring 402, and the two limiting posts on the fixing piece 403 correspond to the limiting holes when the upper top ring 401 and the lower top ring 402 are in contact, as the upper top ring 401 drives the lower top ring 402 to move, the depth of the upper top ring 401 and the lower top ring 402 moving toward the fixing piece 403 increases, the limiting holes continuously move into the limiting posts, connecting the upper and lower fixing rings 203 together, thereby preventing the cable vibration from causing the fixing ring 203 to detach from the cable. At the same time, the friction block 206 that is ejected and the cable are locked to prevent the fixing ring 203 from rotating on the cable.

[0043] In the process of the connecting rod pushing the arc top plate 405 to squeeze the friction block 206, both sides of the friction block 206 are in contact with the side walls of the cavity, and the friction block 206 is sleeved on the limit assembly 500. Therefore, the structure of the limit assembly 500 is disclosed, as shown in FIG. Figure 8 As shown, the limit assembly 500 is composed of a block 501, a fifth spring 502 and a sixth spring 503, the block 501 cooperates with the slot 406 opened on the inclined surface of the arc-shaped top plate 405, and the column to which the block 501 is fixedly connected is sleeved on the friction block 206, the sixth spring 503 sleeves the fifth spring 502, the sixth spring 503 and the friction block 206 are abutted, the fifth spring 502 and the column are fixedly connected, the block 501 and the fifth spring 502 are both fixedly connected to the fixing ring 203, so the friction block 206 pushed out of the arc-shaped top plate 405 slides toward the cable along the inner wall of the cavity, that is, the friction block 206 squeezes the cable to lock the fixing ring 203 and the cable, and as the arc-shaped top plate 405 moves, the arc-shaped top plate 405 gradually contacts the block 501 and causes the block 501 to be stuck in the slot 406.

[0044] Each of the slots 406 is wedge-shaped, and there is an arc surface between adjacent slots 406. The purpose of this is that when the arc-shaped top plate 405 is pressed against the friction block 206, the block 501 can slide from the slot 406 along the arc surface into another slot 406. When the arc-shaped top plate 405 moves in the opposite direction, the side of the block 501 will press against the inner wall of the slot 406, that is, the arc-shaped top plate 405 can only move in one direction.

[0045] Furthermore, the longer the distance that the arc-shaped top plate 405 moves toward the block 501, the longer the portion where the friction block 206 is ejected is, and when the friction block 206 is ejected, the sixth spring 503 in the cavity is compressed, and the arc-shaped top plate 405 squeezes the block 501 so that the column compresses the fifth spring 502. Therefore, the elastic potential energy of the fifth spring 502 and the sixth spring 503 increases, and the reverse forces of the fifth spring 502 and the sixth spring 503 on the column and the friction block 206 respectively increase, thereby making the block 501 more firmly stuck in the slot 406, the pressure between the friction block 206 and the arc-shaped top plate 405 increases, and the fixing ring 203 and the cable are more firmly fixed.

[0046] Return to Figure 8 When releasing the arc-shaped top plate 405, first push the T-shaped rods 205 on both sides upward so that the wedge bodies 404 that are matched on both sides of the T-shaped rods 205 are no longer squeezed. At this time, the T-shaped rods 205 are separated from the wedge bodies 404, and a flat-blade screwdriver is used to insert it into the through groove opened on one side of the bottom fixing ring 203. The through groove connects the column in the cavity and the external environment. The flat-blade screwdriver is used to push the column downward to make the block 501 separate from the slot 406 (at this time, the flat-blade screwdriver rod is against the through groove, and the flat part is against the bottom of the block 501, and the principle of leverage is used to make the block 501 separate from the slot 406), so as to release the arc-shaped top plate 405 in the bottom fixing ring 203, and then release the arc-shaped top plate 405 in the upper fixing ring 203 according to the above operation.

[0047] Return to Figure 5 The two ends of the fixing ring 203 are connected to the internal connecting tube 305, and the elastic cards 304 on both sides are squeezed into the connecting tube 305 at the same time using a clamp. At this time, the vertical rod 302 will move downward for a distance under the squeezing of the elastic cards 304. This distance will not cause the elastic cards 304 below to pop out. According to the above operation, the elastic cards 304 are gradually constrained in the vertical rod 302.

[0048] The device at the bottom of the fixing ring 203 is lifted upward, so that the T-shaped rod 205 moves upward and disengages from the matched wedge body 404. When the T-shaped rods 205 on both sides are pushed to move to both sides to the maximum displacement, the elastic potential energy of the third spring 204 connecting the T-shaped rods 205 on both sides increases. At this time, the bottom of the T-shaped rod 205 is still located between the wedge bodies 404 fixedly connected to the top ring 401 on both sides. The bottom of the T-shaped rod 205 and the wedge bodies 404 on both sides are then released. The T-bar 205 contracts inwards. At this time, the device at the bottom of the fixing ring 203 is released. Under the action of gravity of the anti-vibration hammer assembly 100 at the bottom of the T-bar 205, the T-bar 205 is pulled to squeeze the upper top ring 401 to both sides. The upper top ring 401 drives the lower top ring 402 to move outwards together and connects the upper top ring 401 and the lower top ring 402 together through the fixing piece 403, thereby limiting the upper and lower fixing rings 203, so that the fixing ring 203 can be put on the cable to prevent it from detaching from the cable.
