Technical Field
[0001] The utility model relates to the technical field of vibration damping hammers, in particular to a vibration damping hammer that can be quickly disassembled and assembled. Background Art
[0002] A vibration damping hammer, also known as an anti-vibration hammer, is a protective fitting installed on a conductor (ground wire), mainly used to suppress or reduce the influence of micro-vibration. In high-voltage overhead lines, due to the high pole positions and large spans, the conductors vibrate under the action of wind. This vibration can cause the conductors to fatigue and may lead to fracture. The vibration damping hammer can reduce or eliminate the conductor vibration by generating a movement with the opposite phase to the conductor vibration, extend the service life of the line and improve safety.
[0003] A common vibration damping hammer consists of a wire clamp, a galvanized steel strand and a hammer body. When in use, the wire clamp is clamped outside the line, and then tightened through two groups or four groups of bolt and nut fittings, so that the wire clamp is clamped outside the line. However, since the position where the vibration damping hammer is installed is in the middle of the cable, it is necessary to climb to the middle of the cable. And the bolt and nut fitting method requires tools such as a wrench when disassembling and assembling the vibration damping hammer, resulting in frequent taking when disassembling and assembling the vibration damping hammer. At the same time, the removed bolts and nuts need to be packed and placed before subsequent disassembly and assembly, making the whole process time-consuming and laborious, and unable to meet the working requirements of the vibration damping hammer. Therefore, a vibration damping hammer that can be quickly disassembled and assembled is proposed. Content of the Utility Model
[0004] Aiming at the deficiencies of the prior art, the utility model provides a vibration damping hammer that can be quickly disassembled and assembled to solve the technical problem that tools such as a wrench are required when disassembling and assembling the vibration damping hammer, resulting in frequent taking when disassembling and assembling the vibration damping hammer, making the whole process time-consuming and laborious.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A vibration damping hammer that can be quickly disassembled and assembled, comprising:
[0006] A connecting plate, in which a galvanized steel strand is inserted at the lower side of the interior of the connecting plate, and both the left and right ends of the galvanized steel strand are connected with a basic hammer body;
[0007] Support plates, installed on the left and right sides of the top of the connecting plate, a right-side clamping plate is installed on the top of the right-side support plate, and a left-side clamping plate is installed on the top of the left-side support plate;
[0008] A first screw rod, inserted through a bearing at the lower side of the interior of the right-side clamping plate, a hand wheel is coaxially installed at the right end of the first screw rod, and clamping seats are installed on the inner sides of both the right-side clamping plate and the left-side clamping plate.
[0009] Preferably, the left side of the first screw rod penetrates through the corresponding position inside the left clamping plate, and a limiting disc is coaxially installed at the left end of the first screw rod. Through holes are connected to the upper left and right sides of the tops of the right clamping plate and the left clamping plate.
[0010] Preferably, a slider is installed at the middle position of the bottom of the left clamping plate, and a sliding groove is formed at the position corresponding to the slider inside the left support plate. The slider is inserted into the sliding groove, improving the stability of the left clamping plate during left and right movement.
[0011] Preferably, the inner sides of the clamping seats are all arc-shaped, and the upper and lower parts of the inner sides of the clamping seats are all rounded. A lever is circumferentially connected to the outer part of the handwheel. The added lever facilitates more labor-saving when rotating the handwheel.
[0012] Preferably, expansion hammer bodies are sleeved outside the basic hammer body. Ball bearings are installed at the outer ends of the expansion hammer bodies. Second screw rods are inserted into the inner parts of the ball bearings, and the inner sides of the second screw rods are screwed into the inner part of the basic hammer body. The left and right movement of the expansion hammer body can be driven by rotating the second screw rod, so that the length of the expansion hammer body can be adjusted. Since the length of the anti-vibration hammer determines its natural vibration frequency, a longer anti-vibration hammer usually has a lower natural frequency, while a shorter anti-vibration hammer has a higher natural frequency. By adjusting the length of the expansion hammer body, the aeolian vibration within a specific frequency range can be more effectively matched and suppressed, improving the practicability and adaptability of the anti-vibration hammer.
[0013] Preferably, hinge plates are connected to the upper and lower sides of the outer part of the expansion hammer body. Guide rods are horizontally connected to the inner sides of the hinge plates. Guide plates are connected to the upper and lower sides of the outer part of the basic hammer body. The guide rods penetrate through the inner parts of the guide plates. The inner ends of the guide rods are all threaded structures, and nuts are screwed onto the inner ends of the guide rods, improving the stability of the left and right movement of the expansion hammer body and preventing the expansion hammer body from detaching from the outer part of the basic hammer body at the same time.
[0014] Compared with the prior art, the present utility model provides an anti-vibration hammer that can be quickly disassembled and assembled, having the following beneficial effects:

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0025] The present utility model provides a technical solution, a shockproof hammer that can be quickly disassembled and assembled, including a connecting plate 1, a galvanized steel strand 2, a basic hammer body 3, a support plate 4, a right clamping plate 5, a first screw 6, a limit disc 61, a handwheel 7, a left clamping plate 8, a chute 9, a slider 10, a clamping seat 11, a through ring 12, an extended hammer body 13, a ball bearing 14, a second screw 141, a hinge plate 15, a guide rod 16, a nut 17 and a guide plate 18:
[0026] Please refer to Figure 1 , the lower side inside the connecting plate 1 is inserted with a galvanized steel strand 2, and both the left and right ends of the galvanized steel strand 2 are connected with a basic hammer body 3;
[0027] Please refer to Figure 2, the support plate 4 is installed on the top of the left and right sides of the connecting plate 1. The right clamping plate 5 is installed on the top of the right support plate 4, and the left clamping plate 8 is installed on the top of the left support plate 4;
[0028] Please refer to Figure 3 , the first screw rod 6 is inserted into the lower side of the inside of the right clamping plate 5 through a bearing. A handwheel 7 is coaxially installed at the right end of the first screw rod 6. Please refer to Figure 5 , clamping seats 11 are installed on the inner sides of the right clamping plate 5 and the left clamping plate 8. The inner sides of the clamping seats 11 are all arc-shaped, and the upper and lower parts of the inner sides of the clamping seats 11 are all rounded. A lever is circumferentially connected to the outer circumference of the handwheel 7. The left side of the first screw rod 6 penetrates through the corresponding position inside the left clamping plate 8. Please refer to Figure 4 , a limit disc 61 is coaxially installed at the left end of the first screw rod 6. Please refer to Figure 5 , through-rings 12 are connected to the top of the left and right sides of the right clamping plate 5 and the left clamping plate 8. A slider 10 is installed at the middle position of the bottom of the left clamping plate 8. A chute 9 is opened at the position corresponding to the slider 10 inside the left support plate 4. The slider 10 is inserted into the inside of the chute 9. By rotating the handwheel 7 to drive the rotation of the first screw rod 6, the left clamping plate 8 can be moved left and right, so that the clamping seat 11 inside the left clamping plate 8 clamps the cable, and then the connecting plate 1 can be installed outside the cable, which facilitates the disassembly and assembly of the vibration damper. Since there is no need to use multiple sets of bolt and nut fittings for installation, no tools are required for the disassembly and assembly of the vibration damper, nor is it necessary to disassemble and place the bolts and nuts, which improves the convenience during the installation in the middle of the cable;
[0029] Please refer to Figure 6 , expansion hammer bodies 13 are sleeved on the outside of the basic hammer body 3. Ball bearings 14 are installed at the outer ends of the expansion hammer bodies 13. Please refer to Figure 7 , second screw rods 141 are inserted into the inside of the ball bearings 14, and the inner sides of the second screw rods 141 are screwed into the inside of the basic hammer body 3. Please refer to Figure 6 , hinge plates 15 are connected to the upper and lower sides of the outside of the expansion hammer bodies 13. Guide rods 16 are horizontally connected to the inner sides of the hinge plates 15. Guide plates 18 are connected to the upper and lower sides of the outside of the basic hammer body 3. The guide rods 16 penetrate through the inside of the guide plates 18. The inner ends of the guide rods 16 are all threaded structures, and nuts 17 are screwed on the inner ends of the guide rods 16. By rotating the second screw rods 141, the left and right movement of the expansion hammer bodies 13 can be driven, so that the length of the expansion hammer bodies 13 can be adjusted. Since the length of the vibration damper determines its natural vibration frequency, a longer vibration damper usually has a lower natural frequency, while a shorter vibration damper has a higher natural frequency. By adjusting the length of the expansion hammer bodies 13, the aeolian vibration within a specific frequency range can be more effectively matched and suppressed, which improves the practicality and adaptability of the vibration damper.
[0030] In this solution, by rotating the handwheel 7 to drive the rotation of the first screw rod 6, the left clamping plate 8 can be moved left and right, so that the clamping seat 11 inside the left clamping plate 8 clamps the cable. Furthermore, the connecting plate 1 can be installed outside the cable, which facilitates the disassembly and assembly of the shock damper. Since there is no need to use multiple sets of bolt and nut fittings for installation, no tools are required for the disassembly and assembly of the shock damper, nor is it necessary to disassemble and place the bolts and nuts, which improves the convenience of installation in the middle of the cable. At the same time, by rotating the second screw rod 141, the left and right movement of the expansion hammer body 13 can be driven, so that the length of the expansion hammer body 13 can be adjusted. Since the length of the shock damper determines its natural vibration frequency, a longer shock damper usually has a lower natural frequency, while a shorter shock damper has a higher natural frequency. By adjusting the length of the expansion hammer body 13, the aeolian vibration in a specific frequency range can be more effectively matched and suppressed, which improves the practicability and adaptability of the shock damper.
