Building lifting device

Abstract

The invention discloses a building lifting device relating to the technical field of building construction equipment. The building lifting device comprises a bottom plate, a power device, a counterweight, a stand column, a sleeve, a sway rod, a rotary rack, a bearing, a clamping device, a first pulley, a second pulley, a steel wire rope, a lifting hook and a lifting arm. The power device and the counterweight are arranged on the bottom plate, the power device is connected to the stand column, the sleeve is formed in the stand column, and one end of the sway rod is fixedly connected to the sleeve while the other end of the sway rod is fixedly connected to the bottom plate; the upper end of the stand column is connected to the rotary rack through the bearing and the clamping device, the rotary rack is hinged to the lifting arm, one end of the lifting arm is connected to the second pulley, the first pulley is arranged on the rotary rack, and the steel wire is successively connected to the power device, the second pulley, the first pulley and the lifting hook. The building lifting device disclosed by the invention is relatively small in size, convenient to move by a mobile vehicle and flexible to rotate and lift, and the construction efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of building construction equipment, in particular to a building lifting device. Background technique [0002] Now, in the construction industry, tower cranes or roll machines are used to hoist floors or bricks and mud when building buildings, but these equipment are not suitable for civil buildings. At present, small buildings in rural and townships, especially private households Building a house, due to the limitations of various factors such as the structure of the house, the topography of the house, and economic conditions, etc., most of them are lifted or hoisted by manpower. The floor is installed on the roof, which requires manpower to lift and install. It is because the working site is small and cannot be installed; the power source is difficult to solve and the cost is high.

Problems solved by technology

[0002] Now, in the construction industry, when building a building, tower cranes or rolling machines are used to hoist floors or bricks and mud, but these equipment are not suitable for civil buildings. At present, small buildings in rural and townships, especially private households Building a house, due to the limitations of various factors such as the structure of the house, the topography of the house, and economic conditions, most of them are lifted or hoisted by manpower. The floor is installed on the roof, which requires manpower to lift and install, which is not only laborious and time-consuming, but also extremely unsafe. It is because the work site is small and cannot be installed; the power source is difficult to solve and the cost is high

[0003] The current hoisting device has a large machine base, the equipment is huge and complicated, it is inconvenient to install, it is inconvenient to move and use on different construction sites, and when in use, the rotation, lifting and lifting are not flexible, which affects the construction progress
