Description

Technical Field

[0001] This invention pertains to a type of electrical fitting, specifically a wear-resistant, anti-running, self-locking, and vibration-damping hammer. Background Technology

[0002] High-voltage overhead lines have high pole positions and large spans, making the conductors susceptible to vibration when subjected to wind. The working conditions at the conductor suspension point are most unfavorable during this vibration. Repeated vibrations can lead to fatigue failure due to periodic bending of the conductor. When the span of an overhead line exceeds 120 meters, vibration dampers are generally used for vibration control. Vibration dampers are protective hardware installed on overhead lines to suppress or reduce vibrations caused by light winds.

[0003] Currently, most existing vibration damper structures consist of clamps, hammer heads, and steel strands, typically fixed to the line with bolts. This fixing method is not only cumbersome to operate but also has poor anti-wear and anti-displacement capabilities, affecting operational stability. In practical applications, existing vibration dampers have experienced instances where displacement and wear over time led to conductor breakage, causing line outages and tripping, thus affecting the safe and stable operation of the line. Therefore, it is necessary to provide a wear-resistant, anti-displacement, self-locking vibration damper to solve the above-mentioned technical problems. Summary of the Invention

[0004] The purpose of this invention is to provide a wear-resistant, anti-runaway, self-locking, and vibration-damping hammer that has a self-locking function for clamping lines, strong wear-resistant and anti-runaway capabilities, and good stability in use.

Gears (3) and ratchet (17) are fixedly mounted on the rotating shafts (15). The gears (3) on the left and right sides mesh with the bottom protruding teeth (20) of the anti-vibration hammer clamps (2) above them. The ratchet (17) on the left and right sides is provided with a pawl mechanism on the outside of the ratchet (17) for locking the ratchet (17). The fixed base (7) is fixedly connected to a sliding pull rod (5), and the bottom plate at the lower end of the bracket plate (8) is provided with a movable through hole (16). The sliding pull rod (5) and the movable through hole (16) are slidably engaged. The upper end of the sliding rod (5) is fixedly connected to a rack (4), which is located between the left and right gears (3), and its two sides mesh with the left and right gears (3) respectively.

[0006] Furthermore, the ratchet mechanism includes: two ratchet pawls (18) rotatably mounted on the support plate (8) and respectively engaging with the corresponding ratchet wheel (17); a first fixing rod (19) mounted on the support plate (8); a second fixing rod (21) respectively mounted on the two ratchet pawls (18); and a first tension spring (22) connecting the first fixing rod (19) and the second fixing rod (21).

[0007] Furthermore, the two anti-vibration hammer clamps (2) are provided with arc-shaped grooves (14) on their opposite surfaces, and multiple anti-slip grooves (1) are uniformly provided on the inner side of the arc-shaped grooves (14).

[0008] Furthermore, the anti-vibration hammer clamp (2) and the transverse fixing rod (13) are connected by a sliding groove and a guide rail for sliding guidance, and the anti-vibration hammer clamp (2) moves in opposite directions or in the opposite direction to the transverse fixing rod (13).

[0009] Furthermore, the sliding rod (5) has a rectangular cross-section, and the sliding rod (5) and the rack (4) are integrally formed.

[0010] Furthermore, the wire clamp mounting bracket (12) has a U-shaped structure, and the bracket plate (8) and the wire clamp mounting bracket (12) are integrally formed.

[0011] Furthermore, the tooth gap of the ratchet (17) is 0.13 mm, and the ratchet (17) is located between the gear (3) and the support plate (8).

[0012] Furthermore, the anti-vibration hammer mechanism includes a steel strand (6), which is fixedly connected to a fixed seat (7), and two anti-vibration hammer heads (9) are installed and fixed on the outside of the steel strand (6). The fixed seat (7) is located between the two anti-vibration hammer heads (9).

[0013] Furthermore, the vibration damper mechanism also includes threaded rods (24) installed and fixed at both ends of the steel strand (6), with threaded pipes (10) threaded to the outside of the threaded rods (24), and mass blocks (11) fixedly installed on the outside of the threaded pipes (10).

[0015] This invention places two anti-vibration hammer clamps on the outside of the line and uses the weight of the lower part of the anti-vibration hammer to move the sliding rod down the rack, thereby driving the gear connected by the rack to rotate. In conjunction with the convex teeth, it controls the two anti-vibration hammer clamps to move in opposite directions along the outside of the horizontal fixing rod, thus fixing the anti-vibration hammer to the line. The operation is convenient.

[0016] This invention features a self-locking function and a ratchet mechanism, which enhances the gripping stability of the anti-vibration hammer clamps on the line. The clamps tighten with vibration, preventing slippage. Furthermore, anti-slip grooves are provided on the opposing surfaces of the two anti-vibration hammer clamps to increase friction with the line, prevent rotation, and prevent wear.

[0017] Anti-slip grooves are provided on the opposite sides of the two anti-vibration hammer clamps to increase the friction with the line, prevent rotation, and play a role in preventing wear and running.

[0018] A detachable mass block is added to the outside of the vibration damper hammer head. By pulling up the locking pin, the second tension spring is stretched, causing the lower end of the locking pin to disengage from the locking hole of the threaded rod. Rotating the mass block disengages the threaded pipe connected to it from the outside of the threaded rod, thus allowing the mass block to be disassembled. This facilitates the replacement of mass blocks of different masses according to the usage scenario, improving adaptability and enhancing practicality. Attached Figure Description

Detailed Implementation

[0021] Example 1:

[0022] like Figure 1-8 As shown.

[0023] A wear-resistant, anti-runaway, self-locking anti-vibration hammer includes an anti-vibration hammer mechanism, comprising: a fixed base 7, which is fixedly connected to the anti-vibration hammer mechanism; a support plate 8, with a wire clamp mounting bracket 12 fixedly connected to the upper end of the support plate 8 and a base plate connected to the lower end of the support plate 8; a transverse fixing rod 13 is fixedly connected between the two ends of the wire clamp mounting bracket 12, and anti-vibration hammer wire clamps 2 are slidably guided to the two ends of the transverse fixing rod 13; multiple protruding teeth 20 are respectively provided on the bottom end face of the two anti-vibration hammer wire clamps 2; a rotating shaft 15 is rotatably installed on the left and right sides of the support plate 8, and the rotating shaft 15 is located below the two anti-vibration hammer wire clamps 2. A gear 3 and a ratchet 17 are fixedly installed on the rotating shaft 15, and the gears 3 on the left and right sides mesh with the bottom protruding teeth 20 of the anti-vibration hammer wire clamps 2 above them. A pawl mechanism is provided on the outer side of the ratchet 17 on the left and right sides for locking the ratchet 17. The fixed base 7 is fixedly connected to the sliding rod 5. The bottom plate at the lower end of the bracket plate 8 is provided with a movable through hole 16. The sliding rod 5 is slidably engaged with the movable through hole 16. The upper end of the sliding rod 5 is fixedly connected to the rack 4. The rack 4 is located between the left and right gears 3, and its two sides are respectively engaged with the left and right gears 3.

[0024] The pawl mechanism includes: two pawls 18 rotatably mounted on the support plate 8, which respectively engage with the corresponding ratchet 17; a first fixing rod 19 mounted on the support plate 8; a second fixing rod 21 mounted on each of the two pawls 18; and a first tension spring 22 connecting the first fixing rod 19 and the second fixing rod 21.

[0025] Both anti-vibration hammer clamps 2 have arc-shaped grooves 14 on their opposite surfaces, and multiple anti-slip grooves 1 are evenly provided on the inner side of the arc-shaped grooves 14.

[0026] The anti-vibration hammer clamp 2 and the transverse fixing rod 13 are connected by a sliding groove and a guide rail for sliding guidance. The anti-vibration hammer clamp 2 can move in opposite directions or in the opposite direction to the transverse fixing rod 13.

[0027] The sliding rod 5 has a rectangular cross-section, and the sliding rod 5 and the rack 4 are integrally formed.

[0028] The wire clamp mounting bracket 12 has a U-shaped structure, and the bracket plate 8 and the wire clamp mounting bracket 12 are integrally formed.

[0029] The tooth clearance of ratchet 17 is 0.13 mm, and ratchet 17 is located between gear 3 and bracket plate 8.

[0030] The vibration damper mechanism includes a steel strand 6, which is fixedly connected to a fixed base 7. Two vibration damper heads 9 are installed and fixed on the outside of the steel strand 6, and the fixed base 7 is located between the two vibration damper heads 9.

[0031] The vibration damper mechanism is installed below the line to absorb vibration energy.

[0032] In practice, by placing the two anti-vibration hammer clamps 2 on the outside of the line, and utilizing the self-weight of the lower part of the anti-vibration hammer, the sliding rod 5 pulls the rack 4 downward, thereby driving the gear 3 connected through the rack 4 to rotate. In conjunction with the convex tooth 20, the two anti-vibration hammer clamps 2 are controlled to move in opposite directions along the outside of the transverse fixing rod 13, thus fixing the anti-vibration hammer to the line. The operation is convenient. In addition, a self-locking function is provided to enhance the firmness of the anti-vibration hammer clamps 2 in clamping the line, and it becomes tighter with vibration, playing a role in preventing slippage. Moreover, anti-slip grooves 1 are provided on the opposite surfaces of the two anti-vibration hammer clamps 2, which can increase the friction with the line, prevent rotation, and play a role in preventing wear. This solves the technical problem that the existing anti-vibration hammer structure is mostly composed of clamps, hammer heads and steel strands 6, which are usually fixed to the line by bolts. This fixing method is not only cumbersome to operate, but also has poor anti-wear and anti-slip capabilities, affecting the stability of use.

[0033] like Figure 1 As shown, the anti-vibration hammer clamp 2 is slidably guided to the transverse fixing rod 13. One side of the anti-vibration hammer clamp 2 is in sliding contact with the side wall of the clamp mounting bracket 12, which can prevent the anti-vibration hammer clamp 2 from rotating and ensure its movement stability.

[0034] like Figure 2 As shown, the cross-section of the sliding rod 5 is rectangular, and the sliding rod 5 and the rack 4 are integrally formed, which makes the connection between the sliding rod 5 and the rack 4 firm.

[0035] like Figure 3-4 As shown, the first fixing rod 19 is fixedly connected to the bracket plate 8, and the pawl 18 is rotatably connected to the bracket plate 8 by a connecting shaft.

[0036] like Figure 2 As shown, the wire clamp mounting bracket 12 has a U-shaped structure, and the bracket plate 8 and the wire clamp mounting bracket 12 are integrally formed, which makes the connection between the bracket plate 8 and the wire clamp mounting bracket 12 firm.

[0037] like Figure 3-4 As shown, the tooth clearance of ratchet 17 is 0.13mm, which improves the sensitivity of engagement between pawl 18 and ratchet 17. Furthermore, ratchet 17 is located between gear 3 and bracket plate 8, and rack 4 is located between two gears 3.

[0038] Example 2: like Figure 1-8 As shown, based on Embodiment 1, the present invention provides a technical solution: The vibration damper mechanism includes a steel strand 6, which is fixedly connected to a fixed base 7. Two vibration damper heads 9 are installed and fixed on the outside of the steel strand 6, and the fixed base 7 is located between the two vibration damper heads 9.

[0039] The vibration damper mechanism also includes threaded rods 24 that are installed and fixed at both ends of the steel strand 6. Threaded pipe fittings 10 are screwed to the outside of the threaded rods 24, and mass blocks 11 are fixedly installed on the outside of the threaded pipe fittings 10.

[0040] The vibration damper mechanism also includes a locking hole 26 opened on the outside of the threaded rod 24. A second tension spring 25 is fixedly installed on the outside of the threaded tube 10. A locking pin 23 that passes through the threaded tube 10 is fixedly connected to the upper end of the second tension spring 25. The lower end of the locking pin 23 is inserted into the locking hole 26.

[0041] The locking pin 23 has a T-shaped structure and is located inside the second tension spring 25.

[0042] In practice, a detachable mass block 11 is added to the outside of the anti-vibration hammer head 9. By pulling up the locking pin 23, the second tension spring 25 is stretched, causing the lower end of the locking pin 23 to disengage from the locking hole 26 opened in the threaded rod 24. By rotating the mass block 11, the threaded pipe 10 connected to it disengages from the outside of the threaded rod 24, thereby enabling the mass block 11 to be disassembled. This facilitates the replacement of mass blocks 11 of different masses according to the usage scenario, improving adaptability and enhancing practicality.

[0043] During installation, this technical solution first ensures that the distance between the two anti-vibration hammer clamps 2 is greater than the diameter of the clamped line. Then, the two anti-vibration hammer clamps 2 are placed on the outside of the line, and the bottom of the anti-vibration hammer is loosened. At this time, under the action of gravity, the sliding rod 5 pulls the rack 4 downward, driving the gear 3 to rotate, which in turn drives the anti-vibration hammer clamps 2 connected by the convex teeth 20 to move. The two anti-vibration hammer clamps 2 move closer to each other and clamp the outside of the line. The gear 3 drives the ratchet 17 connected by the rotating shaft 15 to rotate. At this time, under the elastic tension of the first tension spring 22, one end of the pawl 18 engages with the ratchet 17, so that the rack 4 can only move downward. That is, the distance between the two anti-vibration hammer clamps 2 can only decrease under the action of vibration, thus making the clamping of the line more secure. When it is necessary to disassemble the mass block 11, first pull the locking pin 23 to stretch the second tension spring 25, so that the lower end of the locking pin 23 is disengaged from the inside of the locking hole 26. Then rotate the mass block 11 to disengage the threaded pipe 10 connected to it from the outside of the threaded rod 24.
