The invention discloses a construction lifting device for engineering machinery, and belongs to the technical field of engineering machinery. The construction lifting device comprises a base, a control panel is fixedly mounted on the outer side of the base, fixed blocks are fixedly arranged on the two end sides of the outer side of the base correspondingly, screw rods A are rotatably connected in the fixed blocks, the screw rods A penetrate through the fixed blocks to be connected with motors C in a cooperation manner, the outer side of each screw rod A is rotationally sleeved and connected with a screw rod sleeve A, the outer side of each screw rod sleeve A is fixedly sleeved and connected with a bearing sleeve A, the outer side of each bearing sleeve A is fixedly connected with connecting rods, and through holes are formed in the bottom ends of the inner sides of the fixed blocks. The control panel is pressed to control running of a motor B through a controller, a bearing of the motor B drives a rotating disc B to rotate, so that a tooth block B rotates, the tooth block B is engaged with a tooth block A to drive a rotating disc A to rotate, and therefore rotation of a supporting frame can be controlled, the working direction can be changed according to actual needs, and the practicability is higher.

    本发明公开了一种工程机械用施工升降装置,属于工程机械技术领域,包括基座,所述基座外侧固定安装有控制面板,所述基座外侧两端侧分别固定设置有固定块,所述固定块内转动连接有螺杆A,所述螺杆A贯穿固定块与电机C配合连接,所述螺杆A外侧转动套接有丝杆套A,所述丝杆套A外侧固定套接有轴承套A,所述轴承套A外侧固定连接有连杆,所述固定块内侧底端开设有通孔,按动控制面板通过控制器控制电机B的运行,电机B轴承带动转盘B的转动,使得齿块B转动,齿块B与齿块A相啮合,带动转盘A的转动,从而达到可控制支撑架的的转动,可根据实际需要工作方向进行更改,实用性更强。
