Description

[Technical Field]

[0001] This utility model relates to the field of anti-vibration pad technology, specifically an anti-vibration pad for excavators. [Background Technology]

[0002] Industrial rubber excavator damping pads are high-performance elastic elements made of wear-resistant, oil-resistant, and aging-resistant synthetic rubber (such as NBR or NR) and formed through a vulcanization process. Their core function is to absorb vibration and impact energy during excavator operation, reducing equipment structural wear and noise, while also providing anti-slip cushioning protection.

[0003] In existing technologies, ordinary rubber shock-absorbing pads are prone to mis-assembly or mis-fixation during assembly or fixing, which leads to problems with shock absorption and fails to guarantee a sealing effect.

[0004] Based on this, the present invention designs an excavator anti-vibration pad to solve the above problems. [Utility Model Content]

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an excavator anti-vibration pad.

[0006] To achieve the above objectives, an excavator anti-vibration pad is designed, including a pad body;

[0007] The gasket body is equipped with a right-angle buckle to prevent the gasket body from moving and to fix it in place;

[0008] The gasket body is provided with a damping hole assembly for reducing the swaying amplitude caused by vibration during excavator operation;

[0009] The gasket body is equipped with protruding diameter strips for preventing side leakage;

[0010] The gasket body has R-angles arranged in a circumferential array for fitting the machine;

[0011] The side of the pad body is equipped with ear clips for positioning and gripping the vibratory plate.

[0012] The gasket body has a groove for positioning the gasket body in conjunction with the ear clip.

[0013] Furthermore, the shock-absorbing hole assembly includes round holes and irregular holes; three round holes are provided at the upper and lower ends of the gasket body; five irregular holes are provided at the left and right ends of the gasket body; and the right-angle buckle is provided with avoidance holes to avoid the round holes and irregular holes.

[0014] Furthermore, the right-angle buckle is fixedly installed on the four sides of the gasket body to prevent the gasket body from moving in all directions during mechanical vibration.

[0015] Furthermore, the protruding radial strips are arranged in a continuous circumferential array around the gasket body and are fixedly connected to the gasket body to prevent leakage to all four directions.

[0016] Furthermore, the ear clip adopts a semi-circular ear clip design to cushion the vibration generated during machine operation while bearing weight.

[0017] Furthermore, the ear clips are semi-circular, which are used to better cushion the vibrations generated during machine operation while bearing weight.

[0018] Furthermore, the ear clip has a chamfered lip angle for positioning the adsorption vibrating disc.

[0019] Furthermore, the R-angles are arranged in a circumferential array on the inner sidewall of the pad body for fitting the machine.

[0020] Compared with the prior art, this utility model has the following advantages:

[0021] (1) This utility model can achieve more accurate fixing and smooth completion of assembly work, which is more conducive to fixing and assembly;

[0022] (2) This utility model can also reduce the vibration frequency of the excavator through the four-sided ear-shaped design, improve the gripping effect of the vibratory plate, make the seal more solid, and improve the sealing effect of the oil-resistant and heat-resistant gasket. It can be used on special accessories. [Image Description]

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0030] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-5 An excavator anti-vibration pad, comprising a pad body 6;

[0031] A right-angle buckle 1 is installed on the gasket body 6; the right-angle buckle 1 is fixedly installed on the four sides of the gasket body 6; it is used to prevent the gasket body (6) from moving and to fix it.

[0032] The gasket body 6 has round holes 2 and irregular holes 3 to reduce the swaying amplitude caused by vibration during excavator operation; three round holes 2 are opened at the upper and lower ends of the gasket body 6; five irregular holes 3 are opened at the left and right ends of the gasket body 6; the right-angle buckle 1 has clearance holes to avoid the round holes 2 and irregular holes 3; compared with the conventional design that relies on subsequent stamping to complete the holes, the design directly uses a die-cutting molding process to reduce burrs on the product, greatly extend the service life, and reduce the swaying arc caused by vibration during excavator operation. Compared with the traditional gasket positioning structure, the more accurate fixation can smoothly complete the assembly work.

[0033] The gasket body 6 is equipped with protruding diameter strips 4 for preventing side leakage; the protruding diameter strips 4 are arranged in a continuous circular array around the gasket body 6 and are fixedly connected to the gasket body 6.

[0034] The side of the pad body 6 is equipped with ear buckles 7 for positioning and gripping the vibratory plate; and the ear buckles 7 adopt a 270-degree semi-circular ear buckle design to buffer the vibration generated during machine operation while bearing the weight, and alleviate the damage caused by the friction of the machine itself. At the same time, the ear buckles 7 have a chamfered corner to increase the fit and make the seal stronger.

[0035] The gasket body 6 is provided with a groove 8 for positioning the gasket body 6 in conjunction with the ear clip 7;

[0036] The gasket body 6 has multiple R-angles 5 arranged in a circumferential array for fitting and installation;

[0037] In this utility model, the operator positions the gasket body 6 using the ear buckle 7 and the groove 8, and then fixes the gasket body 6 using the right-angle buckle 1. The cooperation between the ear buckle 7 and the groove 8 allows the gasket body 6 to buffer the vibration generated during machine operation while bearing the weight, and alleviate the damage caused by friction of the machine itself. At the same time, the ear buckle 7 has a chamfered hook angle, which increases the fit and makes the seal stronger. Furthermore, the protruding diameter strip 4 on the outer periphery of the gasket body 6 prevents side leakage and makes it easier to fix and assemble. The ear-shaped design on all four sides can reduce the vibration frequency of the excavator, improve the gripping effect of the vibratory disc, and make the seal more solid. The oil-resistant and heat-resistant gasket has a better sealing effect and can be used on special assemblies.
