Crane protection device for building construction

Abstract

The invention provides a crane protection device for building construction and relates to the field of construction cranes. The crane protection device for building construction comprises a crane body, a weighing block is fixedly installed on the left side of the crane body, a first rotary plate is fixedly installed on the upper surface of the crane body, a supporting column is fixedly installed at the top of the first rotary plate, and a first motor is arranged on the left side of the first rotary plate. According to the crane protection device for building construction, by installing a firststeel wire rope, a second steel wire rope and a balance beam, a tank can be adjusted to be balanced, the safety coefficient is improved, and the steel wire ropes are not prone to breaking; by installing a safety air bag and a buffer cushion on the left side of the tank, the safety air bag is opened when the tank is collided so that the life safety of people can be guaranteed; hooks are provided with plug pins, so that the hooks are prevented from disengaging, and accordingly the tank is not prone to falling off; and supporting legs are installed on the two sides of the crane body to support the crane body, the situation that a crane body turns over in the hoisting process as a tank is too heavy is avoided, and the effect of fixing the crane body is achieved.

Description

technical field [0001] The invention relates to the technical field of construction cranes, in particular to a crane protection device for building construction. Background technique [0002] In the process of building a house, it is often encountered that a small amount of heavy objects need to be hoisted while facing. The hooks of traditional cranes usually do not have protective devices. When lifting heavy objects, they rely on their own weight to maintain the balance of the lifting. However, for large objects with unstable center of gravity, it is often difficult to control their center of gravity when lifting, resulting in the center of gravity changing during the lifting process. , so that the hook of the crane shakes and is dangerous. Once the shake occurs, because the lifted objects are large objects, it is difficult to stabilize in a short time, causing damage or even fracture to the fulcrum at the upper end of the hook.

Problems solved by technology

The hooks of traditional cranes usually do not have protective devices. When lifting heavy objects, they rely on their own weight to maintain balance. However, for large objects with an unstable center of gravity, it is often difficult to control their center of gravity during lifting, resulting in a change in the center of gravity during the lifting process. , causing the hook of the crane to shake and cause danger. Once the shaking occurs, it is difficult to stabilize it in a short time because the lifting objects are all large objects, which will cause damage or even breakage to the fulcrum of the upper end of the hook.
