Abstract
Description
Technical Field
[0001] The utility model provides a high-wear-resistant rubber diaphragm for an accumulator of a rock drilling trolley, and relates to the technical field of automobile braking. Background Art
[0002] An accumulator is a device used to store hydraulic energy and is commonly used in various construction machinery, including drilling rigs. The high-wear-resistant rubber diaphragm is a special rubber diaphragm used in the accumulator in the drilling rig. It is a key component inside the accumulator, used to isolate gas and liquid while withstanding high pressure and frequent pressure changes.
[0003] When the hydraulic system needs additional energy, the diaphragm will be pushed by the compressed gas, thereby pushing the hydraulic oil into the system; conversely, when the system pressure is too high, the diaphragm will be squeezed by the hydraulic oil, storing part of the energy in the compressed gas. The diaphragm may wear due to friction during long-term use, resulting in reduced sealing performance. Under high pressure and frequent pressure changes, the diaphragm is prone to deformation or rupture, which makes it easy to wear and lose its original performance in a short period of time, and thus requires frequent replacement. Frequent replacement not only increases maintenance costs, but also brings inconvenience to users.
[0004] Therefore, it is necessary to provide a highly wear-resistant rubber diaphragm for a rock drilling rig accumulator. Utility Model Content

[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.
[0023] Example 1: A highly wear-resistant rubber diaphragm for a rock drilling trolley accumulator, see Figure 1-Figure 3 As shown, it includes a first surface layer 1 and a second surface layer 2, the second surface layer 2 is arranged outside the first surface layer 1, and the first surface layer 1 and the second surface layer 2 together constitute the surface structure of the diaphragm body, the first surface layer 1 and the second surface layer 2 are made of fluororubber material, which has excellent high temperature resistance, oil resistance and chemical resistance. It also includes a first wear-resistant block 101 and a second wear-resistant block 5. The first wear-resistant block 101 is arranged in the middle of the first surface layer 1, and the second wear-resistant block 5 is fixedly connected to the bottom of the second surface layer 2. The first wear-resistant block 101 and the second wear-resistant block 5 are made of rubber material containing glass fiber, carbon fiber or aramid fiber, and this material can improve the tear resistance and wear resistance of rubber.
[0024] When in use, the spring is arranged at one end of the first wear-resistant block 101, and the push rod in the accumulator of the rock drilling trolley contacts the second wear-resistant block 5. When the push rod pushes the second wear-resistant block 5, the second surface layer 2 and the first surface layer 1 will be deformed, and the first wear-resistant block 101 compresses the spring; when the push rod is released, the spring pushes the first wear-resistant block 101 to reset, thereby restoring the second surface layer 2 and the first surface layer 1 to their original state, driving the second wear-resistant block 5 to push the push rod in the accumulator of the rock drilling trolley to reset; through the arrangement of the first wear-resistant block 101 and the second wear-resistant block 5, the push rod and the spring are prevented from directly acting on the first surface layer 1 and the second surface layer 2, preventing the first surface layer 1 and the second surface layer 2 from being damaged due to wear, thereby ensuring the long-term effectiveness of the diaphragm body and extending the service life of the diaphragm body.
[0025] Example 2: Based on Example 1, refer to Figure 3 As shown, a circular groove 501 is formed at the bottom of the second wear-resistant block 5 to fit with the push rod.
[0026] By setting the groove 501, the push rod in the accumulator of the rock drilling trolley can be aligned with the center position of the second wear-resistant block 5 and is not easily offset, thereby avoiding the relative position offset of the push rod and the second wear-resistant block 5.
[0027] See also Figure 2-Figure 6 As shown, it also includes a filler layer 3 filled between the first surface layer 1 and the second surface layer 2, and the filler layer 3 is made of carbon black material; it also includes a reinforcing layer 4 filled between the filler layer 3 and the second surface layer 2, and the reinforcing layer 4 is made of calcium carbonate material.
[0028] The filler layer 3 significantly improves the wear resistance and tensile strength of the diaphragm body, and the reinforcing layer 4 further enhances the tensile performance of the diaphragm body, ensuring that the diaphragm body can remain intact when folded and stretched, thereby extending its service life.
[0029] See also Figure 4 As shown, two sealing rings 6 for preventing air leakage are provided on the edge of the second surface layer 2 by bonding.
[0030] Since the vehicle relies on the change of air pressure on both sides of the diaphragm body to assist braking during braking, during the braking process, the sealing ring 6 can enhance the tightness of the connection between the second surface layer 2 and the accumulator of the drilling rig, avoid air leakage in the cavities on both sides, and ensure the reliability of braking.
[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
