Description

Technical Field

[0001] The utility model relates to the technical field of brakes, in particular to a device for improving the wear of a pin shaft hole of a push head plate of a hydraulic brake. Background Art

[0002] The travel and lifting mechanisms of cranes and trolleys used on site all use hydraulic brakes as the braking components of the operating equipment, and this type of brake is widely used in China. With the years of use, on-site working conditions and frequency, the pin shaft holes of the brake push head plate are often worn, resulting in excessive hole clearance in the later stage, occupying the brake stroke, causing the brake to not be fully opened in the later stage of use. The brake friction pads are frequently worn and replaced, resulting in increased labor intensity and spare parts investment. At the same time, because it cannot be fully opened, it hinders the motor transmission system. For example, negligent inspection causes the motor to stall or overcome resistance and rotate differentially to cause temperature rise, reducing the service life of the motor or burning the motor. Utility Model Content

[0003] The utility model aims to provide a hydraulic brake push head plate pin shaft hole wear improvement device with reasonable structure and reliable use in view of the above-mentioned shortcomings.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A hydraulic brake push head plate pin shaft hole wear improvement device, comprising a push head plate body, and also comprising:

[0006] A first pin hole is provided at one end of the push head plate body.

[0007] A second pin hole is provided on the upper side of the other end of the push head plate body.

[0008] The third pin hole is arranged at the lower side of the other end of the push head plate body.

[0009] The anti-wear mechanism is provided with two anti-wear mechanisms and is respectively provided inside the second pin hole and the third pin hole.

[0010] By setting up an anti-wear mechanism, on the one hand, the wear of the second pin hole and the third pin hole themselves can be effectively reduced, thereby improving the safety and efficiency of the operation. At the same time, it also effectively reduces the replacement and maintenance frequency of the device, thereby reducing the increase in production costs.

[0011] The connecting mechanism is arranged in the middle of the push head plate body.

[0012] The connecting mechanism comprises:

[0013] The first connecting hole is through-opened on one side of the middle part of the push head plate body.

[0014] The second connecting hole is formed through the other side of the middle of the push head plate body.

[0015] The two devices are effectively fixed together by bolts penetrating the first connection hole and the second connection hole.

[0016] As a preferred solution of the utility model,

[0017] There are two fixing holes, which are respectively opened at the upper and lower sides of the other end of the push head plate body;

[0018] The anti-wear mechanism comprises:

[0019] A fixing sleeve, wherein the fixing sleeve is slidably connected to the corresponding second pin hole and the third pin hole;

[0020] A fixing bolt, wherein the fixing bolt is threadedly connected to the corresponding fixing hole and one end of the fixing bolt is threadedly connected to one side of the adjacent fixing sleeve;

[0021] An anti-friction bearing, wherein the anti-friction bearing is fixedly connected to the inner side of the fixed sleeve;

[0022] The anti-friction bearing models are 6905Z and 6904Z self-lubricating bearings;

[0023] When in use, first install the fixing sleeve with the anti-wear bearing inside the second pin hole and the third pin hole respectively, then penetrate the fixing hole with the fixing bolt and fix it with the outer side of the fixing sleeve to fix the fixing sleeve, ensure the stability of the device in use, then penetrate the pin shaft through the anti-wear bearing and start using it. When the anti-wear bearing needs to be replaced during long-term use, it is only necessary to remove the fixing bolt, and the fixing sleeve with the anti-wear bearing can be quickly removed, thereby realizing the rapid replacement of the anti-wear bearing. After the bearing is improved by setting the fixing sleeve, the rotation is more flexible, and the hinge nodes of the brake are more reliable when working in coordination; at the same time, it is also very convenient to replace, because it is a self-lubricating bearing, no additional oil lubrication is required during use, which not only reduces the oil consumption and the oil pollution caused by oil injection to the site, but also increases the use frequency and life of the single plate, reduces the cost of purchasing spare parts, saves equipment failure time and reduces the labor intensity of maintenance personnel.

[0024] Compared with the prior art, the beneficial effects of the utility model are:

[0025] 1. In this device, the anti-wear mechanism set by machine tool processing can effectively reduce the wear of the second pin hole and the third pin hole themselves, improve the safety and efficiency of the operation, and also effectively reduce the replacement and maintenance frequency of the device, thereby reducing the increase in production costs.

[0026] 2. In the present device, when in use, first install the fixing sleeve with the anti-wear bearing inside the second pin hole and the third pin hole respectively, then penetrate the fixing hole with the fixing bolt and fix it to the outside of the fixing sleeve to fix the fixing sleeve, thereby ensuring the stability of the present device in use, then penetrate the pin shaft through the anti-wear bearing and start using it, when the anti-wear bearing needs to be replaced after long-term use, only the fixing bolt needs to be removed, and the fixing sleeve with the anti-wear bearing can be quickly removed, thereby realizing the rapid replacement of the anti-wear bearing, after the bearing is improved by setting the fixing sleeve, etc., the rotation is more flexible, and the hinge nodes of the brake are more reliable when working together; at the same time, it is also very convenient to replace, which not only reduces the cost of spare parts, but also saves equipment failure time, and also reduces the labor intensity of maintenance personnel.
