Lifting appliance with guardrail height and lifting table height being proportional

Abstract

The invention relates to the technical field of housing construction auxiliary tools, and discloses a lifting appliance with the guardrail height and the lifting table height being proportional. The lifting appliance with the guardrail height and the lifting table height being proportional comprises a base frame, wherein a first positioning block is fixedly connected to the front surface of the base frame; a handle drives a first runner so as to enable a steel rope to rotate; the steel rope drives a second runner, a third runner and a fourth runner to rotate so as to enable a connecting blockto move upwards; the connecting block drives a U-shaped top plate to move upwards; a lug on the U-shaped top plate drives an ejector rod to move upwards; and the ejector rod drives a handrail to moveupwards. The rotation of the handle enables the U-shaped top plate to lift up, and a handrail is driven to lift up at the same time, so that the height of the handrail is increased, and an effect on reducing the potential safety hazard is achieved; the U-shaped top plate drives an extension ladder to move upwards so as to enable movable bars of the extension ladder to stretch, so that the height of the extension ladder is increased; and the height of the extension ladder and the height of the U-shaped top plate are consistent, so that an effect on conveniently going up to the U-shaped top plate is achieved.

Description

technical field [0001] The invention relates to the technical field of building construction auxiliary tools, in particular to a lifting device whose height of a guardrail is proportional to the height of a lifting platform. Background technique [0002] Housing construction refers to the internal space formed by structures such as roofs and walls, which can meet the needs of people's living, learning, entertainment, etc. In ancient times, housing buildings were mostly caves dug out. With the development of the construction industry, Today's tall buildings have been created. During the construction of houses, it is inevitable to operate on the top of the house. Although the existing lifting devices can realize high-altitude operations, as the height increases, the safety is gradually decreasing.

[0002] Housing construction refers to the internal space formed by structures such as roofs and walls, which can meet the needs of people's living, learning, entertainment, etc. In ancient times, housing buildings were mostly caves dug out. With the development of the construction industry, Today's tall buildings have been created. During the construction of houses, it is inevitable to operate on the top of the house. Although the existing lifting devices can realize high-altitude operations, as the height increases, the safety is gradually decreasing. When the lifting platform When it is in a low place, the height of the protective fence may be suitable at this time, but as the height increases, the construction workers are easily affected by external factors, such as the thrust of the wind, which will cause the construction personnel's center of gravity to be unstable and shake their bodies. At the same time, the protective fence It is too low to play a protective role, so that the construction workers fall out of the lifting platform, which poses a great threat to the personal safety of the construction workers
