Abstract

本实用新型涉及石油设备领域，具体为一种一体式发动机变速箱减震支架。本实用新型具体技术方案是：包括顶部的支架、底部的支座，其特征在于：所述的支架和支座之间设有减震器；所述的减震器包括与支架连接的上锥壳、与支座连接的下锥壳，上锥壳和下锥壳互相叠置，且接触面上设有减震块。锥壳即外表面为锥形，两个锥壳叠放时，控制上下锥壳的距离，二者的锥面即形成空隙，即可安装减震块减缓发动机引起的振动。本实用新型替代橡胶垫式减震支架，能够解决油田压裂车的振动问题，压裂车的整体振动可降低40%，并且本实用新型的减震器防护性能好，能提高使用寿命50%以上。

Description

一体式发动机变速箱减震支架
技术领域
本实用新型涉及石油设备领域，具体为一种油田压裂车专用的一体式发动机变速箱减震支架。
背景技术
我国现阶段国产的油田压裂车的发动机和变速箱支撑，主要都采用橡胶垫式减震垫，橡胶垫上开孔与支架和底座用螺栓连接，主要缺点表现在：（1）减震效果差，只能抗击纵向的振动，不能抗击横向振动；（2）橡胶垫裸露在外，与周围环境直接接触，寿命差（3）结构复杂，零件种类繁多。
实用新型内容
本实用新型的目的就是针对现有技术存在的缺陷，提供一种结构简单、设计合理、减震效果好且防护性能好的一体式发动机变速箱减震支架。
本实用新型具体技术方案是：包括顶部的支架、底部的支座，其特征在于：所述的支架和支座之间设有减震器；所述的减震器包括与支架连接的上锥壳、与支座连接的下锥壳，上锥壳和下锥壳互相叠置，且接触面上设有减震块。锥壳即外表面为锥形，两个锥壳叠放时，控制上下锥壳的距离，二者的锥面即形成空隙，即可安装减震块减缓发动机引起的振动。
上述方案进一步改进为：
为了提高减震效果，所述的减震器为并置的多个，所述的减震垫为橡胶减震块。
以下提供一种具体的连接结构，所述的下锥壳底部与支座固定，且底部设有凹状缺口，缺口内设有限位挡块；限位挡块连接螺栓一端，且螺栓另一端依次贯穿下锥壳、上锥壳后固定于支架底部。
本实用新型替代橡胶垫式减震支架，能够解决油田压裂车的振动问题，压裂车的整体振动可降低40%，并且本实用新型的减震器防护性能好，能提高使用寿命50%以上。
附图说明
图1是本实用新型的结构示意图；
其中：1，支架，2、上锥壳，3、橡胶减震块，4、下锥壳，5、支座（底座），6、螺栓,7、限位挡块。
具体实施方式
以下结合附图对本实用新型做进一步的说明。
参见图1，一种一体式发动机变速箱减震支架，包括顶部的支架1、底部的支座5，支架1和支座5之间并置两个减震器；减震器包括与支架1连接的上锥壳2、与支座5连接的下锥壳4，上锥壳2和下锥壳4互相叠置，且接触面上设有橡胶减震块3。其中支架1与上锥壳2、支座5与下锥壳4的具体连接方式为：下锥壳4底部与支座5固定为一体，且底部设有凹状缺口，缺口内设有限位挡块7，限位挡块7连接螺栓6一端，且螺栓6另一端依次贯穿下锥壳4、上锥壳2后固定于支架1底部。螺栓6可起到定位作用，降低横向振动。
对于本技术领域的普通技术人员来说，在不脱离本实用新型原理的前提下，有可能对具体尺寸，或者局部结构做出若干改进和润饰，这些改进和润饰也应视为本实用新型的保护范围。

Claims (3)
