本发明实施例采用多级龙门架 1安装输送架 2的升降结构, 将地面与 被困人员所在地之间的救援梯分为多段, 即缩短了云梯凳的长度, 被困人 员通过多级升降的输送架 2到达地面, 通过各输送装置 3的上下运动, 显 著的减小了两次救援工作间的时间, 提高了救援效率。
请参考图 4-图 5 , 其中, 图 4为本发明实施例提供的 A-A方向的龙门 架的剖视图; 图 5为本发明实施例提供的 B的局部放大图。
本发明实施例公开了一种输送架 2与龙门架 1的连接关系, 即输送架 2的一端悬挂在龙门架 1顶端的龙门架横梁 11上, 输送架 2的另一端与相 邻的龙门架 1通过滑动装置相连。 为了减小非工作状态的救援梯的体积, 需要将各个输送架 2收缩到一起, 因此将输送架 2的另一端与相邻的龙门 架 1通过导轨滑块结构相连。 根据实际的应用, 可以在输送架 2的后侧设 置导轨 82, 在相邻的龙门架 1上端的龙门架横梁 11上设置与导轨 82相配 合的滑块 81。 在龙门架 1收缩时, 输送架 2可沿相邻的龙门架 1下滑, 直 至与底端的输送架 2平行; 龙门架 1伸展时, 输送架 2靠滑动装置伸长。 本领域技术人员可以理解的是导轨 82和滑块 81的具体位置不做限制。
具体的, 本发明实施例中提供的输送装置 3为踏杆。
为了实现输送装置 3的自动升降, 在具体实施例中设置了传动机构, 具体的包括设置在输送架 2底端的主动链轮 41、设置在输送架 2顶端的凸 轮 42以及与主动链轮 41和凸轮 42相配合的链条 43。 由于链条 43的传动 需要主动轮和从动轮, 因此, 在输送架 2 的两端分别设置了主动链轮 41 和从动链轮。 由于链条 43在传动过程中会出现偏差, 从而产生阻力, 为了 消除链条 43在传动过程中由于误差造成的卡阻,本发明提供的从动轮为凸 轮链轮 42。 工作时, 驱动装置 4驱动主动链轮 41传动, 然后通过链条 43 带动凸轮链轮 42转动, 从而实现设置在链条 43上的输送装置 3的传动。 被救人员通过与链条 43相连的输送装置 3 , 从被困地达到地面。 相应的, 救援人员可以通过该救援梯从地面到达需要的地方。
本领域的技术人员可以理解的是, 传动装置还可以为丝杠导轨机构, 将输送装置 3与丝杠连接在一起, 可以实现输送装置 3的升降。 本发明提 供的传动机构的目的是为了实现输送装置 3的升降, 因此, 其他可实现输 送装置 3升降的装置也在保护范围。 设置在输送装置 3的两个相对侧边上, 可实现对输送装置 3的稳定运输。 输送装置 3为踏杆时, 踏杆的两端均与链条 43相连, 还可以提高链条 43 的稳定性。
本发明实施例中提供的救援梯还公开了一种过桥装置, 该过桥装置包 括与顶部的龙门架 1相连的固定过桥 51 ; 分别设置在固定过桥 51两端, 与固定过桥 51滑动相连的伸缩过桥 52; 与伸缩过桥 52相连, 带动伸缩过 桥 52沿固定过桥 51滑动的折叠臂 53; 驱动折叠臂 53伸缩的第一伸缩杆 54, 且第一伸缩杆 54的一端与折叠臂 53相连; 分别设置在伸缩过桥 52 的延伸方向的两端, 与伸缩过桥 52滑动相连的伸缩引桥 55。
使用时, 第一伸缩杆 54伸长, 带动折叠臂 53伸展, 从而带动与固定 过桥 51重叠的伸缩过桥 52外伸, 即有效延长了过桥装置的长度, 实现该 救援梯与需要地方的连通; 工作结束后, 第一伸缩杆 54收缩, 带动与折叠 臂 53折叠, 从而带动外伸的伸缩过桥 52收缩, 最终与固定过桥 51重叠, 有效减小了过桥装置的占用空间。 为了进一步增加过桥装置的长度, 本发 明提供的过桥装置还包括设置在伸缩过桥 52延伸的方向两端,与伸缩过桥 52滑动相连的伸缩引桥 55。 使用时, 操作者将伸缩引桥 55从伸缩过桥 52 中伸展出去, 工作结束后, 操作者将伸缩引桥 55滑进伸缩过桥 52中, 使 伸缩引桥 55与伸缩过桥 52重合。本发明提供的第一伸缩杆 54为液压缸杆, 且通过安装在龙门架 1上的伸缩杆支撑板与龙门架 1相连。 实际生产时还 可根据不同的要求选择不同的伸缩杆, 具体的伸缩杆可以为伸缩油缸。
本领域技术人员还可以根据实际需要设置不同的过桥装置, 且均在保 护范围内。
该救援梯在非工作时, 需要将龙门架 1收缩到一起, 以减小该救援梯 的占用体积, 然后将所有的伸缩架均放置在底端的龙门架 1上, 为了保证 底端龙门架 1受力均匀, 本发明在底端龙门架 1上设置了支撑平放状态的 龙门架 1的输送架滚轴 12。
为了便于对该救援梯的工作进行控制, 本发明实施例还提供了用于控 制龙门架 1伸缩、过桥装置伸展以及传动机构启停和速度快慢的控制系统。 根据实际应用, 控制系统可以包括不同功能的控制盘。 优选地, 为了便于 救援工作的协调, 在每个控制盘上均设置有对讲装置 64。
实际生产中, 在每个输送架 2上均设置有用于控制输送装置 3启停和 速度快慢调节的第一控制盘 61。 工作时, 操作人员通过第一控制盘 61使 驱动机构带动传动机构工作, 实现输送装置 3的升降。 实际应用中需要的 输送装置 3的速度不尽相同, 为了适应不同的要求, 在输送架 2上设置的 第一控制盘 61还具有调节输送装置 3传动快慢的功能。在此对于第一控制 盘 61的个数不做限制。
在与过桥装置相连的输送架 2 上设置有用于控制过桥装置伸展或收 缩、 龙门架 1升降以及输送装置 3升降的第二控制盘 62。 工作时, 当过桥 装置上升到需要的高度时, 操作者启动过桥装置展开按鈕, 以连通救援梯 与被困人员所在地。 为了实现操作者在不同高度上作业, 第二控制盘 62 还具有调整龙门架 1升降的功能, 同时还具有调节每个输送装置 3升降及 速度的功能。本领域技术人员可以理解的是, 第二控制盘 62还可以根据不 同的需要设置不同的功能, 在此不再——赘述。
为了便于对整个装置的控制, 控制系统还包括总控制盘 63 , 且该总控 制盘 63可以控制整个救援梯的工作,包括该救援梯的升降和龙门架 1的伸 缩等, 即总控制盘 63控制该救援梯从初始状态到救援状态的转换。
在救援工作过程中, 被困人员或救援人员在相邻的输送架 2之间转移 中, 为了保证救援人员的安全, 同时给被困人员或救援人员提供一个稳定 的空间, 因此在各个输送架 2底端设置了供人员站立的緩台 21。 在救援工 作过程中, 被救人员从过桥装置到达设置在输送架 2上的输送装置 3 , 通 过传动装置将输送装置 3上被困人员输送到该输送架 2的緩台 21 , 并通过 緩台 21位置转移到相邻的输送架 2上, 最终到达地面。 同理位于地面上的 救援人员可以通过上述方式达到被困人员所在地, 以实施救援工作。
本发明实施例还提供了一种救援车, 包括救援车底盘 7、 设置在救援 车底盘 7上的救援梯和检测被困人员所在地的定位装置, 其中, 该救援梯 为如上述实施例中所公开的救援梯, 且救援梯与救援车底盘 7通过第二伸 缩杆 71铰接。 在具体实施例中第二伸缩杆 71可以为液压虹杆, 实际应用 时, 可以才艮据不同的需要设置不同结构的伸缩杆。
该救援车的工作过程: 定位装置检测到被困人员所在地后, 救援车到 达需要的位置,救援人员启动总控制盘 63的启动按¾,使安装在救援车底 盘 7上的处于收缩状态的平衡支腿 72外伸并支撑在地面上,然后第二伸缩 杆 71外伸, 并将与第二伸缩杆 71铰接的救援梯从支撑横杆 73上推起,最 终使救援梯与救援车底盘 7成 90。 布置; 救援人员将设置在底端伸缩架上 的落地踏板 22展开, 并连通各个输送架 2的緩台 21 , 进入与过桥装置相 连的伸缩架的緩台 21内; 然后启动第一控制盘 61上的龙门架 1伸缩按 ¾ 和输送装置 3升降按 ¾, 使龙门架 1伸展的同时救援人员随上升的输送装 置 3快速到达被困人员所在地, 根据不同的需要, 救援人员还可以站在不 同的緩台 21 , 以便救援工作的展开; 救援人员调节第二控制盘 62, 使过桥 装置展开, 为救援梯与被困人员所在地之间提供通道; 操作人员调节第二 控制盘 62, 使输送装置 3下降, 被困人员到达过桥装置后通过下降的输送 装置 3到达该输送架 2上的緩台 21 , 并通过緩台 21到达与该输送架 2相 邻的输送架 2上的输送装置 3上, 直至到达地面; 所有被困人员到达地面 后, 救援人员调节第二控制盘 62, 使过桥装置收缩, 然后控制龙门架 1收 缩; 救援人员到达地面后, 收起落地踏板 22并控制总控制盘 63 , 使平衡 支腿 72收缩, 第二伸缩杆 71收缩, 直至救援梯平放在救援车底盘 7上, 并由支撑横杆 73支撑, 即完成了整个救援工作。
根据实际需要, 总控制盘 63还可以控制平衡支腿 72的伸缩, 控制用 于驱动该救援梯工作的发电机、 发动机、 起动机和液压站的启停。 本领域 技术人员可以理解的是, 总控制盘 63 的功能可以根据需要增加不同的功 能, 且均在保护范围内。
本说明书中各个实施例采用递进的方式描述, 每个实施例重点说明的 都是与其他实施例的不同之处, 各个实施例之间相同相似部分互相参见即 可。
虽然本发明已以较佳实施例披露如上, 然而并非用以限定本发明。 任 何熟悉本领域的技术人员, 在不脱离本发明技术方案范围情况下, 都可利 用上述揭示的方法和技术内容对本发明技术方案作出许多可能的变动和修 饰, 或修改为等同变化的等效实施例。 因此, 凡是未脱离本发明技术方案 变化及修饰, 均仍属于本发明技术方案保护的范围内。
