具体地,在该第一种实施例中,如图 1所示,转塔台 1包括上平板 11、 下平板 12及连接于二者之间的立筒 13, 该上平板 11、 下平板 12以及立筒 13三者围成了与回转机构连接的孔; 在该结构的基础上, 上平板 11与下 平板 12分别通过至少一个第一定位杆件 21与支腿安装座连接, 该种结构 设计可以使得转塔台 1与支腿安装座之间的连接变得稳固。
具体地, 在上述第一种实施例中, 可以对支腿安装座的结构做出进一 步改进, 比如, 如图 1所示, 支腿安装座包括上盒装结构件 31及与其连接 的下盒装结构件 32, 二者开设有与支腿铰接的铰接孔; 在此基础上, 为了 进一步提高连接的可靠性, 任一个支腿安装座与转塔台 1之间连接的第一 定位杆件 21的数量可以为三个, 其中两个第一定位杆件 21可以连接于上 平板 11与上盒装结构件 31之间,剩余一个第一定位杆件 21可以连接于下 平板 12与下盒装结构件 32之间。
进一步地, 在上述第一种实施例中, 支腿安装座可以区分为前支腿安 装座 3和后支腿安装座 4, 需要说明的是, 用来连接位于泵车车头的一侧 支腿的两个支腿安装座为前支腿安装座 3, 用来连接位于泵车车尾一侧支 腿的两个支腿安装座为后支腿安装座 4; 在该种结构的基础上, 如图 1所 示, 两个前支腿安装座 3之间、 及两个后支腿安装座 4之间均进一步通过 第二定位杆件 22连接。该种结构设计使得两个前支腿安装座 3之间、及两 个后支腿安装座 4之间的相对位置变得稳固, 从而提高了固定转塔整体结 构的稳定性。 具体地,如图 1所示,前支腿安装座 3的上盒装结构件 31与下盒装结 构件 32通过一个连接杆件 33连接; 在该结构的基础上, 如图 1所示, 第 二定位杆件 22的数量可以为两个,一个连接于两个前支腿安装座 3的下盒 装结构件 32之间,另一个连接于两个前支腿安装座 3的连接杆件 33之间。 该种结构设计可以进一步提高两个前支腿安装座 3之间连接的可靠性。
具体地,如图 1所示,后支腿安装座 4的上盒装结构件 31与下盒装结 构件 32通过两个连接杆件 33连接; 在该结构的基础上, 如图 1所示, 第 二定位杆件 22的数量可以为两个,一个连接于两个后支腿安装座 4的下盒 装结构件 32之间,另一个连接于两个后支腿安装座 4的处于外侧的连接杆 件 33之间。该种结构设计可以进一步提高两个后支腿安装座 4之间连接的 可靠性。
在上述第一种实施例中, 还可以做出进一步设计。 比如, 如图 1所示, 前支腿安装座 3和后支腿安装座 4之间还可以通过第三定位杆件 23连接, 具体地, 该第三定位杆件 23可以连接于前支腿安装座 3的下盒装结构件 32与后支腿安装座 4的下盒装结构件 32之间。 该种结构设计使得前支腿 安装座 3和后支腿安装座 4之间的相对位置变得稳固, 从而进一步提高了 固定转塔整体结构的稳固性。
此外, 为了提高上平板 11、 下平板 12和立筒 13三者之间结构的可靠 性, 如图 1所示, 在第一定位杆件 21位置, 立筒 13的外侧壁上可以进一 步设有分别与上平板 11和下平板 12连接的立筋板 14。
此外, 在上述技术方案中, 可以作出进一步改进。 比如, 转塔台靠近 两个前支腿安装座 3 , 并该转塔台 1上第一定位杆件 21的连接部位位于前 支腿安装座 3上第一定位杆件 21的连接部位的正上方,以便前支腿安装座 3与转塔台 1之间的第一定位杆件 21竖直设置。 该种结构设计可以增强前 支腿安装座 3上的第一定位杆件 21对转塔台 1的支撑强度,从而能够进一 步提高本发明所提供的固定转塔的结构强度, 保证其工作的可靠性和安全 性。
再者, 在上述技术方案中, 还可以作出另一种改进。 比如, 如图 1所 示, 转塔台 1设于各个支腿安装座围成空间的上方, 以便各所述第一定位 杆件 21倾斜连接于所述转塔台 1与所述支腿安装座之间。在该种结构设计 中, 如图 1所示, 各个第一定位杆件 21如众星换月般倾斜连接于转塔台 1 的周围,各个第一定位杆件 21的支撑力汇聚于转塔台上,从而能够进一步 提高对转塔台 1的支撑强度, 进而能够进一步提高本发明所提供的固定转 塔的结构强度, 保证其工作的可靠性和安全性。 在上文基础技术方案的基 础上, 还可以做出进一步改进, 从而得到本发明的第二种实施例。 具体地, 在该第二种实施例中, 如图 2所示, 转塔台 1 包括上平板 11、 下平板 12 及连接于二者之间沿周向分布的多个立杆 15, 该三者围成了与回转结构铰 接的孔; 在上述结构的基础上, 下平板 12和立杆 15分别通过至少一个第 一定位杆件 21与支腿安装座连接。该种结构设计可以使得转塔台 1与支腿 安装座之间的连接变得稳固。
在该第二种实施例中, 同上述第一种实施例, 支腿安装座可以区分为 前支腿安装座 3和后支腿安装座 4, 用来连接位于泵车车头的一侧支腿的 两个支腿安装座为前支腿安装座 3, 用来连接位于泵车车尾一侧支腿的两 个支腿安装座为后支腿安装座 4。
在上述第二种实施例中, 可以对支腿安装座的结构做出具体设计。 比 如, 如图 2所示, 支腿安装座包括竖直设置的主垫板 41、 连接于主垫板 41 的外侧的两个支腿座板 42及设于两个支腿座板 42之间的支腿座盒 43 , 该 支腿座盒 43与两个支腿座板 42均开设有与支腿铰接的铰接孔; 在上述结 构的基础上, 第一定位杆件 21均连接于主垫板 41上。
具体地, 为了提高连接的可靠性, 如图 1所示, 第一定位杆件 21包括 三层, 分为上层杆件 211、 中层杆件 212及下层杆件 213, 并每层杆件的数 量为两个; 在此基础上, 如图 1所示, 上层杆件 211的一端连接于主垫板 41的上部, 另一端连接于相对应的两个立杆 15的上部; 中层杆件 212的 一端连接于主垫板 41的中部,另一端连接于相对应的两个立杆 15的中部; 下层杆件 213的一端连接于主垫板 41的下部, 另一端连接于下平板 12的 底壁上。 三层杆件层层分布, 该种结构能够显著提高转塔台 1与支腿安装 座之间连接的可靠性。
此外, 为了进一步提高固定转塔整体结构的可靠性, 下层杆件 213可 以相互焊接在一起, 亦即, 如图 2所示, 任一个支腿安装座上的任一个下 层杆件 213均与其相邻的支腿安装座的至少一个下层杆件 213实现连接。 该种结构设计使得下层杆件 213之间环环相扣, 显然能够提高整体结构的 可靠性。
此外, 本发明还提供一种混凝土泵车, 包括回转机构和支腿; 混凝土 泵车还包括上述任一种技术方案中的固定转塔, 回转机构配合于转塔台 1 , 支腿安装于支腿安装座上。该混凝土泵车的其他部分,可以参照现有技术, 本文不再展开。
以上对本发明所提供的混凝土泵车及其固定转塔进行了详细介绍。 本 的说明只是用于帮助理解本发明的方法及其核心思想。 应当指出, 对于本 技术领域的普通技术人员来说, 在不脱离本发明原理的前提下, 还可以对 本发明进行若干改进和修饰, 这些改进和修饰也落入本发明权利要求的保 护范围内。
