Description

A buffer clamp for cable erection

Technical field

The invention relates to the field of cable installation, and in particular to a buffer clamp for cable erection.

Background technique

The buffer clamp for cable erection is an installation clamp that is used to install and fix the cable and also has a vibration-absorbing effect when the cable is installed at high altitude. It can reduce the impact of cable vibration while the cable is being installed. It is a commonly used accessory during cable installation. Applications In various high-altitude cable erection and installation situations;

In the comparison document, a buffer clamp for cable erection (Application No.: 202022248977.9), although it improves the safety of cable installation, the protective pad plays the role of protecting the cable and improving its stability, but in the cable During erection and installation, a circular ring structure is used to clamp the cable up and down. After the cable is clamped and fixed, the vibration displacement in the front and rear directions of the cable cannot be buffered, resulting in the inability to effectively reduce the vibration of the cable. At the same time, The installation of upper and lower clamping makes the buffer displacement on the side small, thereby reducing the vibration damping effect on the side. The cable cannot be fully installed and used for vibration damping. Moreover, when the cable is installed, a separate section of the cable is fixed at a single point. The front and rear sections of the cable fixed position will vibrate, and the clamp can move elastically. Therefore, when buffering and damping, the vibration of the front and rear sections of the cable fixed point will impact the clamp installation point, thereby increasing the rebound vibration frequency, resulting in failure. Stable vibration reduction. When installing the cable, a single section is fixed, which is not convenient for the cable to be pulled back and released, so it is not convenient for the erection, installation and use of the cable.

It should be noted that the present invention is a buffer clamp for cable erection. When in use, the screw holes 2 in the fixed installation plate 1 are used to pass screws and be installed on the cable rack, so that the entire clamp is installed on the cable rack. The clamping cover 28 is first separated from the fixed clamp block 27. After the cable body 29 is placed above the fixed clamp block 27, the clamping cover 28 is then combined and installed with the fixed clamp block 27, so that the fixed clamp block 27 is connected to the clamp block 27. The tight cover plate 28 clamps and fixes the cable body 29 to install the cable body 29. When the cable body 29 vibrates, the vibrations in the up, down, front and rear directions are transmitted to the connecting rod 20, and the movement of the connecting rod 20 affects the four transverse planes. The shock absorber 16 and the transverse spring 17 perform telescopic extrusion, and the buffering and contraction of the transverse shock absorber 16 and the transverse spring 17 are used to buffer and dampen the vibration in the up, down, left and right directions;

Through the side vibration reduction of the buffer base structure 5, the vibration displacement in the side direction of the cable body 29 drives the ring support frame 13 and the installation ring 14 to move left and right, and then the connecting moving plate 11 in the middle of the two ring support frames 13 drives the buffer moving block 8 moves left and right in the installation base plate 6, and the buffer moving block 8 telescopically squeezes the transverse shock absorber 9 and the transverse spring 10, thereby utilizing the buffering contraction of the transverse shock absorber 9 and the transverse spring 10 to perform side buffering and damping. vibration;

Through the double-section clamping of the fixed clamp block 27 and the clamping cover plate 28, the two sets of fixed clamp blocks 27 and the clamping cover plate 28 are clamped at two sections outside the cable body 29. When the cable body 29 vibrates, the two sets of The cable body 29 between the fixed clamp block 27 and the clamping cover 28 remains stable, thereby separating the vibrations of the front and rear sections of the cable body 29 at the fixed position, so that the vibrations of the front and rear sections of the cable body 29 will not conflict. The repeated rebound vibration frequency is reduced, and the vibration is more stably transmitted to the transverse shock absorber 9 and the transverse shock absorber 16 for vibration reduction;

Through the telescopic adjustment of the telescopic installation structure 21, the first extension rod 25 and the second extension rod 26 connecting the front and rear fixed clamp blocks 27 can be telescopically adjusted in the two telescopic grooves 23 in the telescopic installation plate 22, and then through the locking screws 24 Therefore, after the cable body 29 is clamped and fixed, the distance between the two sets of fixed clamp blocks 27 and the clamping cover 28 is changed through the expansion and contraction of the first extension rod 25 and the second extension rod 26, and the The cable body 29 is pulled back or released to adjust the position of the clamp when installing the cable body 29 .
