Description

一种可折叠引进机构 技术领域
本发明涉及塔式起重机技术领域，具体涉及一种可折叠引进机构。
背景技术
塔机的引进机构是塔机自顶升安装过程中的重要结构，安装塔机时需要利用引进机构将标准节引入爬升架内，引进的标准节与下方标准节采用销轴安装的方式，达到提升塔机高度加快安装进程的目的。现有技术中，通过采用的引进机构，因其引进梁为一体式，导致起重臂上的吊钩的最小工作幅度受限，最大起重量减小，同时实际安装所需空间大，不稳定，需在安装空间内移动较大幅度才能安装，费时费力，且存在安全隐患。
发明内容
本发明的目的在于提供一种可折叠引进机构，以解决现有技术中存在的占用吊钩移动空间及安装不方便的问题。
为实现上述目的，本发明的一种可折叠引进机构，包括引进梁I、引进梁II、支撑组件，所述引进梁I固定在特殊节的下方，其一端与所述引进梁II的一端铰接，支撑组件用于所述引进梁II平放与折叠后的支撑。
进一步地，所述支撑组件包括拉杆I，所述拉杆I一端固定在所述特殊节的上部，另一端与所述引进梁II铰接，用于所述引进梁II平放时的支撑。
进一步地，所述支撑组件还包括拉杆II，其一端固定在所述特殊节的上部，另一端与所述引进梁II铰接，用于所述引进梁II折叠时的支撑。
进一步地，所述引进梁I和所述引进梁II通过销轴连接。
进一步地，所述引进梁I与所述特殊节的下方通过销轴连接。
本发明的有益效果是：通过将引进梁设置为可折叠式，一是为起重臂上的吊钩提供了更多的行走距离，其起吊物重量可进一步提高；二是当引进梁II折叠起来时，可以使整个起重机的支撑架更稳定；三是由于引进梁I与特殊节之间，引进梁I与引进梁II之间均是通过销轴连接，其拆卸比较方便，也便于运输。
附图说明
图1是本发明的结构示意图；
图2是引进机构收起时的示意图；
图中，1-引进梁I，2-引进梁II，3-拉杆I，4-拉杆II,5-特殊节。
具体实施方式
下面结合附图及具体实施例对本发明作进一步详细说明。
如图1所示，一种可折叠引进机构，包括引进梁I1、引进梁II2、支撑组件，引进梁I1固定在特殊节5的下方，其一端与引进梁II2的一端铰接，支撑组件用于引进梁II2平放与折叠后的支撑。其中引进梁I1和引进梁II2是一种H型钢，它们主要起滑道的作用，在两个引进梁的边侧挂设有引进小车，引进小车用于将待安装的标准节送到特殊节5下方的空间内。特殊节5是标准节和回转支座的过度节，是一中空框架支撑结构，内部中空的长方体，其下方设置有两个横梁，引进梁I1设置于横梁中间位置的下面，与两个横梁保持垂直，并通过销轴与横梁连接，这样，引进小车其行程就可以沿伸到特殊节内部，继而其吊运的待安装标准节也可以进入爬升架内部，其中销轴连接，便于拆卸与安装。
支撑组件包括拉杆I3，拉杆I3一端固定在特殊节5的上部的横梁中间位置，另一端与引进梁II2铰接，用于引进梁II2平放时的支撑。其中，引进梁I1和引进梁II2通过销轴连接，一是便于折叠，二是便于拆卸与安装。如图2所示，支撑组件还包括拉杆II4，其一端固定在特殊节5的上部，另一端与引进梁II2铰接，用于引进梁II2折叠时的支撑。
上述两个引进梁设置成可折叠方式，由于引进梁II2的长度一般在三米左右，这样起重臂上的吊钩在通向标准节方向的行程增加，吊钩的起吊重物的能力得到加强，这在现实的起吊作业中起到很好的扩能作用。另外，引进梁一般较重，引进梁II2工作完成，折叠起来后，可以加强起重机的稳定性。
拉杆I3和拉杆II4的长度不一样，引进机构工作时，用拉杆I3，引进机构工作完成后，引进梁折叠起来，换成拉杆II4。

  1. 当然，支撑组件也可以采用钢丝绳与动滑轮的方式，同样可以起到采用拉杆支撑的作用。
    上面结合附图对本发明的实施方式作了详细说明，但是本发明并不限于此，在所属技术领域的技术人员所具备的知识范围内，在不脱离本发明宗旨的前提下可以作出的各种变化，都处于本发明权利要求的保护范围之内。
