The invention discloses a supporting leg telescopic control mechanism and a crane, belongs to the technical field of engineering machinery, and aims to solve the problems that in the prior art, a three-section supporting leg technology occupies most space in a supporting leg, so that the interior of a box is reinforced, other structures are designed to be limited, an oil cylinder pipeline is prone to abrasion and oil leakage, assembly and maintenance are inconvenient, and cost is high. And the cost is high. The device comprises a fixing leg and a two-stage oil cylinder, a first rope row is arranged at one end of a fixing base, one end of the first rope row bypasses a first pulley and is fixed to one side of the bottom of a third-stage supporting leg, a second rope row is arranged at the other end of the fixing base, and one end of the second rope row bypasses a second pulley and is fixed to one side of the outer wall of the third-stage supporting leg. A mechanism with the two-stage oil cylinder, the first rope row and the second rope row is adopted to drive the three sections of supporting legs to stretch out and draw back in a reciprocating mode, the internal space is saved, an oil pipe and a valve set are easier to arrange, the fault rate is reduced, installation and maintenance are convenient, the stretching-out and drawing-back process is stable and reliable, and cost is relatively low.
本发明公开了一种工程机械技术领域的支腿伸缩控制机构及起重机,旨在解决现有技术中三节支腿技术占用了支腿内部大部分的空间,使得箱型内部加强及设计其他结构受限,并且导致油缸管路易磨损漏油,装配维修不便,同时成本较高的问题。其包括固定腿和两级油缸,固定座一端设有第一绳排,第一绳排的一端绕过第一滑轮并固定于三级支腿底部一侧,固定座另一端设有第二绳排,第二绳排一端绕过第二滑轮并固定于三级支腿外壁一侧;本发明采用一个两级油缸加第一绳排和第二绳排的机构,驱动三节支腿往复伸缩,节省了内部空间,油管和阀组更容易布置,降低了故障率,安装维修方便,伸缩过程稳定可靠,而且其成本相对较低。
