The invention discloses a construction engineering manual lifting device, which comprises a box body, two direction-changing fixed pulleys and two pulley blocks symmetrically fixed on the top of the wall body, and two triangular suspender rods are symmetrically installed on the upper surface of the box body. All fixed pulleys are installed on each of the triangular suspenders, and the two fixed pulleys are respectively articulated with two pulley blocks, and each of the direction-changing fixed pulleys and the pulley block on the same side are jointly wound with an adjustment rope. The present invention enables the box body to be easily lifted by manpower through the pulley block, and through the cooperation of the inner ratchet of the control box and the spring pawl, the box body can be raised to hover at a fixed point and increase safety. Linkage makes it easier for the control box to lower the box body, and the return spring cooperates with the special-shaped shaft to avoid the danger of hand slipping and further increase the safety of the device.
Description
technical field [0001] The invention relates to the field of construction engineering, in particular to a manual lifting device for construction engineering. Background technique [0002] In the process of building construction, scaffolding construction needs to be climbed, which is relatively dangerous. Therefore, construction personnel need to use lifting devices to carry out construction on the wall to reduce danger and improve work efficiency. [0003] The existing lifting device is usually hoisted by a motor, which needs to be controlled by a worker on the bottom surface, which increases the labor force. The controller is located inside the lifting device. Due to the use of electric energy control, it cannot accurately stop at the required working position, and it takes a lot of work. Adjust up and down twice, and consume a lot of power. Contents of the invention [0004] The purpose of the present invention is to solve the disadvantages in the prior art that the gro...
