Description

Technical Field

[0001] The invention relates to the technical field of mechanical structures, in particular to a self-tightening cable anti-vibration hammer. 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. At present, the anti-vibration hammers used in the line are mainly bolt-type anti-vibration hammers and pre-twisted wire anti-vibration hammers. The fastening bolts of the bolt-type anti-vibration hammer will loosen due to the vibration of the breeze, causing the anti-vibration hammer to slip. In practical applications, the pre-twisted wire anti-vibration hammer was found to loosen along the direction of the conductor thread. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a self-tightening cable anti-vibration hammer, which tightens the cable in a self-tightening manner, and uses a spring to absorb the vibration energy generated by the cable being blown by wind, thereby avoiding the problems of bolt loosening and loosening of bolts in bolt-type anti-vibration hammers and pre-twisted wire anti-vibration hammers in the prior art.

[0004] A self-tightening cable vibration-proof hammer comprises a sliding rod, a sliding base and a self-tightening clamp, wherein the sliding rod is fixedly mounted on the wire rod along the cable setting direction, the sliding base is slidably mounted on the sliding rod, the sliding base is elastically buffered connected to the self-tightening clamp, and the self-tightening clamp is movably mounted on the outer wall of the cable; the self-tightening clamp comprises a middle clamp plate, a cross-hinged frame and a self-tightening sleeve, wherein the middle clamp plate is elastically buffered connected to the sliding base, the interior of the middle clamp plate cooperates to clamp the cable, and the two ends of the middle clamp plate are hingedly connected to the cross-hinged frame; the other end of the cross-hinged frame is hingedly connected to the self-tightening sleeve mounted on the cable.

[0005] Moreover, a plurality of guide rods are fixedly mounted on the side wall of the sliding base, and the guide rods are slidably mounted on the middle clamping plate, and buffer springs are mounted on the guide rods; one end of the buffer spring is fixedly connected to the side wall of the sliding base, and the other end of the buffer spring is buffer-supported on the outer wall of the middle clamping plate.

[0006] Moreover, connecting ears are fixedly mounted on both side walls of the middle clamping plate, and the connecting ears are slidably sleeved on the guide rods.

[0007] Moreover, anti-skid patterns that fit on the outer wall of the cable are uniformly formed on the inner wall of the middle clamping plate and the self-tightening sleeve.

[0008] The advantages and technical effects of the present invention are:

[0009] The self-tightening cable vibration-proof hammer of the present invention provides a limit support with a certain buffer margin for the cable through a sliding rod and a sliding base, and supports the middle clamping plate through a buffer spring on the sliding base, and the two straight plates of the middle clamping plate can slide on the guide rod with an adjustable spacing, thereby promoting the cross-hinged frames on both sides of the middle clamping plate to change the support angle, thereby providing the self-tightening sleeve with its clamping force on the cable, and no matter in which axial direction the cable moves and at the same time swings in the radial direction of the cable, the self-tightening sleeves on both sides of the middle clamping plate can fit tightly on the outer wall of the cable, thereby realizing the self-tightening function of the self-tightening sleeve, and finally, through the anti-slip patterns on the self-tightening sleeve and the inner wall of the middle clamping plate, it is further ensured that the cable and the self-tightening clamping hoop will not have excessive axial relative displacement.

[0010] The self-tightening cable vibration-proof hammer of the present invention can realize self-tightening of the axial sliding of the cable and elastic buffering of the radial swing of the cable. The buffer spring absorbs the vibration energy of the cable, effectively avoiding the defect that rigid connections such as screws are easy to loosen under frequent vibrations. The structure is simple and the cost is low. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings. It should be noted that the embodiments are illustrative, not restrictive, and the protection scope of the present invention cannot be limited thereby.

[0018] A self-tightening cable vibration-proof hammer comprises a slide bar 1, a slide base 8 and a self-tightening clamp, wherein the slide bar is fixedly mounted on the wire rod along the setting direction of the cable 2, the slide base is slidably mounted on the slide bar, the slide base is elastically buffered connected to the self-tightening clamp, and the self-tightening clamp is movably mounted on the outer wall of the cable; the self-tightening clamp comprises a middle clamp plate 5, a cross-hinged frame 4 and a self-tightening sleeve 3, wherein the middle clamp plate is elastically buffered connected to the slide base, the interior of the middle clamp plate cooperates to clamp the cable, and the two ends of the middle clamp plate are hingedly connected to the cross-hinged frame; the other end of the cross-hinged frame is hingedly connected to the self-tightening sleeve mounted on the cable.

[0019] Moreover, a plurality of guide rods 6 are fixedly mounted on the side wall of the sliding base, and the guide rods are slidably mounted on the middle clamping plate, and buffer springs 7 are mounted on the guide rods; one end of the buffer spring is fixedly connected to the side wall of the sliding base, and the other end of the buffer spring is buffer-supported on the outer wall of the middle clamping plate.

[0020] Moreover, connecting ears 9 are fixedly mounted on both side walls of the middle clamping plate, and the connecting ears are slidably sleeved on the guide rods.

[0021] Furthermore, anti-slip patterns 14 are uniformly formed on the inner wall of the middle clamping plate and the self-tightening sleeve to fit on the outer wall of the cable.

[0022] In addition, in the present invention, preferably, the cross-hinged frame adopts a mature product in the prior art.

[0023] In addition, in the present invention, the self-tightening sleeve is preferably divided into an upper sleeve and a lower sleeve, and the upper sleeve and the lower sleeve are both composed of two symmetrically arranged self-tightening sheets 13 fixedly connected by bolts.

[0024] In addition, the present invention preferably comprises an upper splint 10 and a lower splint 12, wherein the upper splint is limited by a nut 11 at the end of the guide rod, the outer wall of the lower splint is elastically supported by a buffer spring, and both side walls of the upper splint and the lower splint are hingedly connected to the cross hinge frame.

[0025] To more clearly illustrate the specific implementation of the present invention, an example is provided below:

[0026] The self-tightening cable vibration-proof hammer of the present invention needs to be installed by first fixing a sliding rod with a sliding base on the wire rod, then fitting a buffer spring on the sliding rod, and then slidingly fitting a lower clamping plate on the sliding rod, and then adjusting the two sliding rods to both sides of the cable respectively, and finally installing the upper clamping plate to complete the fixation of the middle clamping plate; then hingedly installing a cross-hinged frame on both sides of the middle clamping plate, and finally fixing a plurality of self-tightening sheets at the other end of the cross-hinged frame by bolts to form a self-tightening sleeve to hold the cable tightly, thereby completing the connection and installation of the self-tightening sleeve.

[0027] The self-tightening cable anti-vibration hammer of the present invention solves the problem of vibration limitation of the cable caused by wind force and realizes buffer support of the cable. The vibration energy of the cable is absorbed by the reset spring. When the cable slides axially, the support angle of the cross-hinged frame changes to provide the clamping force of the self-tightening sleeve. When the cable swings radially, the buffer spring provides buffer support, which effectively avoids the collision between the cable and the pole. After the vibration energy of the cable is absorbed, it will not be transmitted to the bolt connection position, thus avoiding the failure problem of the anti-vibration hammer caused by loose bolts.

[0028] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the appended claims of the present invention.
