Abstract
本实用新型具体为一种液压支架行走装置，解决了现有的液压支架功能繁琐、造价昂贵、操作复杂，而且不能与液压支架上所附加的临时支护装置、收煤装置等配合使用的问题。液压支架行走装置，包括主液压支架和副液压支架，主液压支架和副液压支架包括两个顶梁，两个顶梁之间利用横梁架和横向推移千斤顶连接，每个顶梁下方利用液压支柱固定在底梁上，两个底梁之间设有煤溜机尾槽，两个底梁和煤溜机尾槽通过横向推移千斤顶连接，主液压支架和副液压支架利用设在主架底梁和副架底梁之间的行走千斤顶连接。本实用新型结构合理、实用方便，使用寿命长且造价低廉。
Description
液压支架行走装置
技术领域
[0001] 本实用新型涉及煤矿井下的液压支架，具体为一种液压支架行走装置。
背景技术
[0002] 传统的液压支架一般是不具有行走装置的。即使具有行走装置的液压支架，其功能繁琐、造价昂贵、操作复杂，而且一般的液压支架的行走装置不能与液压支架上所附加的临时支护装置、收煤装置等配合使用。
发明内容
[0003] 本实用新型为了解决现有的液压支架功能繁琐、造价昂贵、操作复杂，而且不能与液压支架上所附加的临时支护装置、收煤装置等配合使用的问题，提供了一种液压支架行
走装置。
[0004] 本实用新型是采用如下技术方案实现的:液压支架行走装置，包括主液压支架和副液压支架，主液压支架包括两个主架顶梁，两个主架顶梁之间利用横梁架和横向推移千斤顶连接，每个主架顶梁下方利用液压支柱固定在主架底梁上，两个主架底梁之间设有煤溜机尾槽，两个主架底梁和煤溜机尾槽通过横向推移千斤顶连接；副液压支架包括两个副架顶梁，两个副架顶梁之间利用横梁架和横向推移千斤顶连接，每个副架顶梁下方利用液压支柱固定在副主架底梁上，两个副架底梁之间设有煤溜机尾槽，两个副架底梁和煤溜机尾槽通过横向推移千斤顶连接；主液压支架和副液压支架利用设在主架底梁和副架底梁之间的行走千斤顶连接。
[0005] 使用时，开始行走前，主液压支架的液压支柱收回，副液压支架的液压支柱升紧(接顶严密，初撑力达到标准的80%)，通过主液压支架和副液压支架之间的行走千斤顶的伸缩，实现主液压支架的前进后退；主液压支架到达指定位置时，将主液压支架的液压支柱升紧、副液压支架的液压支柱收回，通过主液压支架和副液压支架之间的行走千斤顶的伸缩，实现副液压支架的前进后退；依次交替运行实现整个液压支架的前进后退。横向推移千斤顶在液压支架工作时作为横向加固杆使用，在工作之前，可以利用横向推移千斤顶调整主液压支架和副液压支架的宽度，适应不同宽度的巷道。
[0006] 本实用新型的有益效果如下:利用主副两个液压支架和行走千斤顶，实现了液压支架的行走。本实用新型结构合理、实用方便，使用寿命长且造价低廉。
附图说明
[0007] 图1为本实用新型的结构示意图。
[0008] 图中:1-副架顶梁，2-主架顶梁，3-横梁架，4-横向推移千斤顶，5-副架底梁，6-主架底梁，7-行走千斤顶，8-煤溜机尾槽，9-液压支柱。
具体实施方式[0009] 液压支架行走装置，包括主液压支架和副液压支架，主液压支架包括两个主架顶梁2，两个主架顶梁2之间利用横梁架3和横向推移千斤顶4连接，每个主架顶梁2下方利用液压支柱9固定在主架底梁6上，两个主架底梁6之间设有煤溜机尾槽8，两个主架底梁6和煤溜机尾槽8通过横向推移千斤顶4连接；副液压支架包括两个副架顶梁1，两个副架顶梁I之间利用横梁架3和横向推移千斤顶4连接，每个副架顶梁I下方利用液压支柱9固定在副主架底梁5上，两个副架底梁5之间设有煤溜机尾槽8，两个副架底梁5和煤溜机尾槽8通过横向推移千斤顶4连接；主液压支架和副液压支架利用设在主架底梁6和副架底梁5之间的行走千斤顶7连接。
