Description

分体式铰车带轴快速转动装置 技术领域
本发明涉及机械技术领域, 尤其是涉及一种汽车上使用的捆 绑工具。 背景技术
在汽车运输货物过程中, 货物通常需要捆绑, 以防止货物在 汽车行驶时脱落或者相互碰撞而造成丢失或者损坏。 用绳索直接 捆绑的方式虽然很常用, 但费时费力, 且难以将货物绑紧, 存在 着安全隐患。
铰车是一种先进的捆绑工具, 采用铰车捆绑货物既方便又安 全, 深受广大驾驶员的欢迎。 目前广泛使用的铰车设有一个支架 和带轴, 带轴装于支架上, 且可以转动。 捆绑器的捆绑带绕在带 轴上。 通过转动带轴, 把绑于货物上的捆绑带收紧, 就可以将货 物捆绑起来。 现有的转动带轴收紧捆绑带的方法是将一根撬棒插 入带轴一端的撬棒孔, 扳动撬棒, 使带轴转动。 由于铰车是固定 于车体上的, 受位置限制, 在操作过程中当扳动撬棒使带轴转动 一定的角度后, 必须拔出撬棒插入另一个撬棒孔, 以便继续转动 带轴。 显而易见, 这样操作费时费力, 同时, 由于不断地使撬棒 拔出和插入, 容易造成人体手指或者其他部位损伤。
为此, 本发明人申请了名为铰车带轴快速转动装置(申请号:
200410052805. 7 ) 的专利, 包括一个固定座和一个转动体, 固定 座与带轴固连在一起, 转动体套接于固定座的侧部, 且在固定座 与转动体的接触面处设有一个单向联动机构, 在转动体上有至少 一个撬棒孔。 铰车采用上述转动装置后, 由于采用了单向联动机 构, 在整个操作过程中, 不必将撬棒拨出, 使用安全可靠且省力, 不会对产品或者人体造成损伤。 但是, 由于上述的带轴快速转动 装置是与铰车成一体化设置的, 这样在每一个带轴伸出端都必须 设置这样一个转动装置, 因此造成了铰车制作难度、 制作工序的 增加; 而且每一个铰车的制作成本也相应增加。 另外, 一旦转动 装置出现故障无法修复时, 就必须将整个铰车替换, 增加了使用 成本, 使用的灵活性也较差。
发明的公开
本发明的目的是针对上述问题, 提供一种能够与铰车配合使 用, 便于随时拆卸和安装, 使用的灵活性高, 制作成本低廉, 且 加工制作方便的分体式铰车带轴快速转动装置; 解决了现有技术 所存在的带轴转动装置与铰车一体化设置, 增加了制作难度和制 作工序, 生产成本高等技术问题。
本发明的另一目的是针对上述问题, 提供一种便于日常维修 保养, 一旦损坏无法修复时, 只需更换本装置即可, 保证铰车能 够继续使用的分体式铰车带轴快速转动装置; 解决了现有技术所 存在的不利于维护保养, 一旦损坏就会造成整个铰车报废, 使用 成本较高等技术问题。
本发明的还一目的是针对上述问题, 提供一种使铰车带轴能 够快速转动, 在操作时不必将撬棒拔出, 从而操作方便、 省力, 提高铰车的捆绑速度, 确保操作过程的安全可靠的分体式铰车带 轴快速转动装置; 解决了现有技术所存在的操作过程繁琐, 工作 效率不高, 费时费力, 使用时需要不断地使撬棒拔出和插入等技 术问题。
为达到上述目的, 本发明采用了下列技术方案: 本分体式铰 车带轴快速转动装置, 设置于铰车支架侧部的带轴伸出端, 包括 一个带轴接头和一个转动体, 在转动体上至少有一个撬棒孔, 所 述转动体套接于带轴接头的侧部, 在带轴接头和转动体的接触面 处设有一个单向联动机构,其特征在于,所述的带轴伸出端至少有 一个销孔, 带轴接头可以插入或者套于带轴伸出端上, 在带轴接 头和带轴伸出端之间设有一个利用销轴插入销孔使两者相固连且 可以脱卸的连接机构。
在使用时, 铰车支架固定于汽车上, 本装置装于铰车支架侧 部的带轴伸出端, 且与带轴伸出端相连接。 操作时, 将撬棒插入 撬棒孔, 来回反复地扳动撬棒, 利用单向联动机构, 就可使铰车 的带轴沿单向转动, 将卷于带轴上的捆绑带收紧。
在本发明中, 利用销轴使本装置与铰车之间成为可脱卸的分 体式结构。 在需要使用的时候可以方便地装配上去。 不仅有效地 降低了生产制作成本, 而且有效地解决了现有技术存在的缺陷。
在上述的分体式铰车带轴快速转动装置中, 所述的连接机构 为设于带轴接头一端的可以插入带轴伸出端的柱体, 销轴穿过带 轴伸出端上相应的销孔并固连在柱体上。 通过这种结构可将带轴 伸出端和带轴接头固连起来。 在此结构中, 带轴快速转动装置的 连接机构是插于带轴伸出端中的。
这里销轴与柱体的配合方式可以多种多样, 为了安全可靠, 在上述的分体式铰车带轴快速转动装置中,所述的销孔有若干个, 每个销孔中均设有销轴, 且销轴与柱体之间通过螺紋相连接。
在上述的分体式铰车带轴快速转动装置中, 所述的连接机构 为带轴接头一端具有一可以容纳带轴伸出端的内腔, 且在内腔侧 壁上设有销孔,销轴贯穿带轴伸出端上的销孔和内腔侧壁的销孔。 通过这种连接机构也可将带轴伸出端和带轴接头固连起来。 在此 结构中,带轴快速转动装置的连接机构是将带轴伸出端包容起来。
为了进一步提高带轴伸出端和带轴接头固连的强度, 在上述 的分体式铰车带轴快速转动装置中, 所述的销轴上设有通孔, 在 通孔内穿设有一根传动销, 传动销两端插于带轴伸出端的销孔和 带轴接头的传动销孔内。 一般情况下, 这里的传动销和销轴是相 互垂直设置的, 两者形成十字结构。 当然两者非垂直设置也是可 行的, 并且在其上可以设置不止一根的传动销和销轴。
在上述的分体式铰车带轴快速转动装置中, 在带轴接头的端 部设有凸起的铆接块, 在铆接块上铆接有挡块, 转动体套于带轴 接头后, 通过挡块的外缘挡住转动体。 这是带轴接头与转动体的 一种连接方式。
也可以是另一种方式, 即在上述的分体式铰车带轴快速转动 装置中, 在带轴接头和转动体之间设有连接螺钉, 转动体套于带 轴接头后, 通过连接螺钉的顶部外缘挡住转动体。
在上述的分体式铰车带轴快速转动装置中, 所述的单向联动 机构包括位于转动体与带轴接头接触面处的转动体上的若干弹簧 孔, 每个弹簧孔内由内至外均装有一根弹簧和一个顶柱, 顶柱在 弹簧的作用下顶压于带轴接头的侧部, 在带轴接头的侧部设有与 弹簧孔相同数量且位置对应的滑槽, 滑槽的一个侧面为一个沿转 动体转动方向向一侧倾斜且延伸至带轴接头侧表面的斜面, 另一 个侧面为垂直于带轴接头侧表面的直面。
在使用过程中, 当沿着滑槽斜面倾斜的方向转动转动体时, 在弹簧作用下伸出弹簧孔的顶柱会顺着滑槽的斜面向上移动, 使 顶柱缩入弹簧孔内, 直至顶柱顶压于固定座的侧表面上。 接着, 顶柱进入下一个滑槽内, 又重复这一过程。 显然, 在转动体沿着 这一方向转动时, 带轴接头是固定不动的, 也就是说转动体不能 带动带轴转动。
反之, 如果使转动体沿相反方向转动, 则当顶柱进入滑槽后, 顶柱会被滑槽的直面挡住, 从而顶柱无法滑过滑槽。 这样, 转动 体与带轴接头成为联动关系。 在转动体的转动力矩作用下, 带轴 接头也一起转动, 最后带动带轴转动。
在上述的分体式铰车带轴快速转动装置中, 所述的滑槽均匀 分布于带轴接头的侧部, 弹簧孔也均匀分布于转动体上。
在上述的分体式铰车带轴快速转动装置中, 所述的转动体上 设有两个用于插撬棒的撬棒孔, 上述两个撬棒孔相对设置。
本转动装置应用于铰车时, 需要使转动体与带轴接头联动时 转动体的转动方向与铰车带轴卷带的方向相一致。 在使用时, 只 要将撬棒插入转动体的撬棒孔中, 来回反复地扳动撬棒。 由于只 能使带轴接头沿单向转动, 故可以带动带轴将捆绑带收紧。 使用 完毕后可以将本装置整体卸下,用本装置与其他的铰车配合使用。 也就是多个铰车只要采用一个转动装置就可以实现带轴的收紧工 与现有的技术相比, 本分体式铰车带轴快速转动装置的优点 在于:
1、 采用分体式结构, 有效地简化了铰车的结构, 降低了生产 成本, 并且多个铰车可以共用一个转动装置即可完成捆绑带的收 紧。
2、 便于日常维修保养, 一旦转动装置损坏无法修复时, 只需 更换即可, 保证铰车能够继续使用, 有效利用资源。
3、 便于随时拆卸和安装, 使用的灵活性高, 操作过程简便。
4、 在操作时不必将撬棒拔出, 从而操作方便、 省力, 提高铰 车的捆绑速度, 确保操作过程的安全可靠。 附图说明

下面通过具体实施例, 并结合附图, 对本发明的技术方案做 进一步具体的说明。
实施例一
如图 1、 图 2、 图 3、 图 4所示, 本分体式铰车带轴快速转动 装置设置在铰车支架 1侧部的带轴伸出端 5a处。本装置包括一个 带轴接头 2和一个转动体 3, 在转动体 3上开设有用于插撬棒的 撬棒孔 4,撬棒孔 4为两个且相对的设置在转动体 3上。在铰车支 架 1的另一侧设有与带轴 5固连的单向棘轮 23, 带轴 5的一端穿 过支架 1上的带轴孔 la伸出支架 1侧面, 棘轮 23就固连在带轴 5的伸出处。在单向棘轮 23的一侧设有一个用于卡住单向棘轮 23 的棘爪 24, 见图 5所示。 这样可以保证带轴 5在收卷的时候单向 转动。 在本实施例中, 棘爪轴 22固连在绞车支架 1侧面,棘爪 24 套在棘爪轴 22 上, 使得棘爪 24 能够转动, 但不能从棘爪轴 22 上脱出。
在铰车支架 1的另一侧也有带轴 5伸出, 即带轴伸出端 5a, 如图 1、 图 2和图 3所示。 本实施例中, 带轴伸出端 5a侧面开设 有四个均匀分布的销孔 5aa。
如图 1和图 2所示, 本快速转动装置就设置于上述的带轴伸 出端 5a处, 包括一个带轴接头 2和一个转动体 3, 转动体 3套接 于带轴接头 2的侧部, 在带轴接头 2和转动体 3的接触面处设有 一个单向联动机构。
带轴接头 2的侧面设有两个相对设置的销孔 2a, 见图 6和图 7所示。在带轴接头 2与上述的带轴伸出端 5a之间有一个可以脱 卸的连接机构。 本实施例中, 如图 3、 图 4、 图 8、 图 9所示, 该 连接机构为带轴接头 2—端的一个可以容纳带轴伸出端 5a的内腔 9, 带轴伸出端 5a就装于该内腔 9中。 销轴 8贯穿带轴伸出端 5a 上相对应的两个销孔 5aa并插入带轴接头 2内腔 9侧壁上的销孔 2a内, 将带轴伸出端 5a和带轴接头 2固连起来。
如图 1和图 2所示,在本实施例中,在销轴 8上设有通孔 11, 在通孔 11 内穿有一根传动销 12。传动销 12贯穿带轴接头 2上的 两个传动销孔 2b、 带轴伸出端 5a上的两个销孔 5aa及销轴 8上 的通孔 11, 从而使销轴 8得到定位。 另外, 在传动销 12的末端 开孔, 用一根销子 10穿入该孔, 以防止传动销 12脱出。 这里的 传动销 12和销轴 8是相互垂直设置。
如图 3、 图 4、 图 10、 图 11、 图 12所示, 单向联动机构包括 转动体 3上均匀分布的六个弹簧孔 16, 弹簧孔 16位于转动体 3 与带轴接头 2接触面处,每个弹簧孔 16内由内至外均装有一根弹 簧 17和一个顶柱 18, 顶柱 18在弹簧 17的作用下顶压于带轴接 ¾ 2的侧部。在带轴接头 2的侧部设有与弹簧孔 16相同数量且位 置对应的滑槽 19, 滑槽 19的一个侧面为一个沿转动体 3转动方 向向一侧倾斜且延伸至带轴接头 2侧表面的斜面 20, 另一个侧面 为垂直于带轴接头 2侧表面的直面 21。 显然, 由于弹簧孔 16是 均匀分布的, 因此滑槽 19也均匀分布于带轴接头 2的侧部。
如图 3、 图 4所示, 在带轴接头 2和转动体 3之间设有连接 螺钉 15, 转动体 3套于带轴接头 2后, 通过连接螺钉 15的顶部 外缘挡住转动体 3, 使带轴接头 2与转动体 3连接在一起。 如图 11、 图 13所示的另一个连接方式, 在带轴接头 2与连接螺钉 15 的接触面设有相互啮合的单向齿 26。 采用这样的结构, 转动体 3 不会脱离带轴接头 2, 但转动体 3可以相对于带轴接头 2转动。 单向齿 26可以保证连接螺钉 15与带轴接头 2紧密固连, 防止在 使用过程中松动。
' 在使用时,将铰车的带轴伸出端 5a插入带轴接头 2的内腔 9, 将带轴接头 2和带轴伸出端 5a上相应的销孔 2a、销孔 5aa对准, 然后插入销轴 8, 并且在销轴 8的通孔 11 内插入传动销 12。这样 就将本发明提供的装置与铰车固连起来了。 本实施例中, 转动体 3上有两个撬棒孔 4, 且相对设置。 在使用铰车时, 将一根撬棒插 入位于转动体 3中的撬棒孔 4内, 反复来回扳动撬棒, 利用单向 联动机构使带轴 5单向转动, .以收紧卷于带轴 5上的捆绑带。
完成上述操作以后, 本装置可以继续连在铰车上, 也可以将 其卸下用于其它铰车上或者储存起来下次使用。 在脱卸时, 首先 拨出销子 10将传动销 12拆下, 然后拔出销轴 8, 就可使本发明 提供的装置与铰车分离了。
另外, 如图 1和图 2所示, 在转动体 3及带轴接头 2的外侧 还可套一个外罩 6, 以防止雨水或者杂物进入转动体 3与带轴接 头 2的连接处。 实施例二
如图 14、 图 15、 图 16所示, 这是本发明提供的快速转动装 置的另一种实施方式。 在本实施例中, 带轴接头 2的一端为一个 柱体 7, 柱体 7插于带轴伸出端 5a内。 在带轴伸出端 5a上开有 四个均匀分布的销孔 5aa, 四个销轴 8穿过带轴伸出端 5a上相应 的销孔 5aa固连在柱体 7的螺紋孔 25上。销轴 8与柱体 7通过螺 纹配合将带轴伸出端 5a和带轴接头 2固连。
如图 14所示, 在带轴接头 2的端部设有凸起的铆接块 13, 在铆接块 13上铆接有挡块 14, 转动体 3套于带轴接头 2后, 通 过挡块 14的外缘挡住转动体 3。从而使转动体 3不会脱离带轴接 头 2。 '
在使用时, 将带轴接头 2的柱体 7插入带轴伸出端 5a, 销轴 8穿过带轴伸出端 5a上相应的销孔 5aa通过螺纹结构与柱体 7固 连。 为了保证销轴 8与柱体 7紧密固连, 在销轴 8还可以套上弹 簧衬片 27。这样就将本发明提供的快速转动装置与铰车固连起来 了。
本实施例二的快速转动装置用法与实施例一完全相同。 本实 施例中, 转动体 3 上的撬棒孔 4有四个, 且均匀分布, 见图 17 所示。
在本装置使用完毕并需要卸下时, 用扳手之类的工具将销轴 8旋下, 就可以使本装置与铰车脱离。
实施例二的其它结构均与实施例一类同, 本文不作赘述。 本文中所描述的具体实施例仅仅是对本发明精神作举例说 明。 本发明所属技术领域的技术人员可以对所描述的具体实施例 做各种各样的修改或补充或采用类似的方式替代, 但并不会偏离 本发明的精神或者超越所附权利要求书所定义的范围。
尽管本文较多地使用了铰车支架 1、 带轴孔 l a、 带轴接头 2、 销孔 2a、 传动销孔 2b、 转动体 3、 撬棒孔 4、 带轴 5、 带轴伸出 端 5a、 销孔 5aa、 外罩 6、 柱体 7、 销轴 8、 内腔 9、 销子 10、 通 孔 11、 传动销 12、 铆接块 13、 挡块 14、连接螺钉 15、 弹簧孔 16、 弹簧 17、 顶柱 18、 滑槽 19、 斜面 20、 直面 21、 棘爪轴 22、 单向 棘轮 23、 棘爪 24、 螺纹孔 25、 单向齿 26、 弹簧衬片 27等术语, 但并不排除使用其它术语的可能性。 使用这些术语仅仅是为了更 方便地描述和解释本发明的本质; 把它们解释成任何一种附加的 限制都是与本发明精神相违背的。
