Abstract

The invention discloses a building engineering manual lifting device. The device comprises a box, two direction-changing fixed pulleys symmetrically fixed to the top of a wall and two pulley blocks, wherein two triangular suspenders are symmetrically mounted on the upper surface of the box, a fixed wheel is mounted on each triangular suspender, the two fixed wheels are connected with the two pulley blocks respectively in a hanging mode, and an adjustment rope is wound around each direction-changing fixed pulley and the corresponding pulley block at the same side. According to the device, the box can be easily lifted by manpower through the pulley blocks, the box can be lifted to be suspended at a fixed point through cooperation of an inner ratchet and a spring pawl in a control box, and safety is enhanced; a special-shaped rotary shaft is in linkage with the spring pawl through a connecting rope, and the control box can conveniently place the box down; and through a reset spring in cooperation with the special-shaped rotary shaft, danger caused by hand slip is avoided, and the safety of the device is further enhanced.

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...
