Description

Technical Field

[0001] The utility model belongs to the field of lamp lifting devices, in particular to a lifting device. Background Art

[0002] Existing high-altitude lighting lamps are divided into fixed lighting lamps and lifting lighting lamps. They are high-altitude lighting lamps used for specific lighting venues, such as stadiums, high-speed rail stations, exhibition venues, etc. with high ceilings. For the sake of brightness, this type of lamp is generally large in size and can illuminate a wide range. The weight of this large lamp is also relatively heavy, usually more than 10 kilograms, and some can reach hundreds of pounds depending on the complexity of the lamp. As a result, high-altitude lighting lamps are affected by their own weight and the installation environment, which brings many difficulties to the construction party in the installation, maintenance, and construction safety of lamps. For example, fixed lighting lamps are difficult to install on the ground, and when the staff needs to carry out maintenance, they also need to use a lifting vehicle to help, which increases the difficulty of high-altitude operations. The high-altitude lighting fixtures in the prior art are generally fixed on the ceiling by steel wire ropes. Although the lifting lighting fixtures can be lowered from the high altitude to a height that can be operated by ground personnel by remote control with the help of a lifter, the steel wire rope may be worn or broken during use. At this time, this large lighting fixture will fall rapidly from the ceiling, and will produce a huge impact force on the ground due to the influence of gravity acceleration, etc., which may endanger people passing by or property placed on the ground, causing serious unnecessary losses. Therefore, the installation of high-altitude lighting fixtures in the prior art has at least one of the following defects: First, some of the fixed high-altitude lighting fixtures in the prior art need to be lifted to the high altitude for installation or maintenance by the help of a lift; second, if the steel wire rope fixing the lighting fixture is damaged, the impact force of the heavy lighting fixture on the ground caused by the accelerated fall of the heavy lighting fixture itself cannot be underestimated, which increases the unsafety of the lighting fixture.
