随着我国城市化进程的加快，经济的快速发展，国家基本建设的规模越来越大，需要吊装的物品的重量及起升高度越来越大，履带式起重机越来越显示其优越性，履带式起重机得到了迅猛的发展。履带起重机按照工况一般分为主臂和副臂，如图1和图2所示。通常主臂的臂架截面（H×G）要大于副臂的臂架截面，同时臂节间的接头、销轴尺寸主臂的也要大于副臂。With the acceleration of my country's urbanization process and rapid economic development, the scale of national infrastructure is getting larger and larger, and the weight and lifting height of items that need to be hoisted are getting larger and larger. Crawler cranes are showing their superiority more and more. Crawler cranes have developed rapidly. Crawler cranes are generally divided into main boom and auxiliary boom according to the working conditions, as shown in Figure 1 and Figure 2. Usually the jib section (H×G) of the main arm is larger than that of the jib, and the size of the joints and pin shafts between the jib sections is also larger than that of the jib.
为了提高履带起重机的起升高度及工作幅同时提高臂架系统的利用率，引申出混合主臂工况，混合主臂下部为主臂臂节，上部为副臂臂节，中间通过一过渡节连接。过渡节一端的截面尺寸与主臂相同，另一端的截面尺寸与副臂相同；同时与主臂连接端的臂架接头、销轴尺寸与主臂相同，与副臂连接端的臂架接头、销轴尺寸与副臂相同。整个臂架系统材料及运输等成本较高；该过渡节仅在混合主臂工况中使用，利用率较低。In order to increase the lifting height and working width of the crawler crane and improve the utilization rate of the boom system, the mixed main boom working condition is extended. The lower part of the mixed main boom is the main boom section, the upper part is the auxiliary boom section, and a transition section passes through the middle connect. The section size of one end of the transition section is the same as that of the main arm, and the section size of the other end is the same as that of the auxiliary arm; at the same time, the size of the jib joint and pin shaft at the connection end of the main arm is the same as that of the main arm, and the size of the jib joint and pin shaft at the connection end of the auxiliary arm Dimensions are the same as the jib. The material and transportation costs of the entire boom system are relatively high; the transition section is only used in mixed main boom conditions, and the utilization rate is low.
本发明在于提供一种副臂系统，该副臂系统平时作为副臂使用，在需要混合主臂工况时，该副臂系统可直接与主臂连接形成混合主臂，无需过渡节。The present invention provides a jib system, which is used as a jib at ordinary times, and can be directly connected with the main jib to form a mixed main jib when a mixed main jib is required without a transition joint.
