Abstract

The invention belongs to an element on a hanger and particularly relates to a movable illumination device for a suspension arm of a tower crane. The movable illumination device comprises a device body, and is characterized in that the device body is composed of an illumination mechanism and a walking mechanism; the illumination mechanism comprises a reversed footpace and five illumination lamps arranged on four side faces and the bottom face of the reversed footpace; the walking mechanism is composed of protruding blocks, wheels and slide rails; the protruding blocks are arranged on the four corners of a top plane of the reversed footpace; circular holes are formed in the protruding blocks; wheel shafts of the wheels penetrate through the circular holes to be fixed on the protruding blocks and be tangent with guide rails of the suspension arm of the tower crane; and the slide rails are arranged in the middle of the top of the reversed foot space through fastening screws. Compared with the prior art, the movable illumination device disclosed by the invention is simple in structure and convenient to detach; the danger degree of a worker in a process of replacing a lamp is effectively reduced; and sufficient light is provided so that normal construction can be carried out under the condition that the light is insufficient.

Description

technical field [0001] The invention belongs to a component on a sling, in particular to a movable illuminating device used on the boom of a tower crane. Background technique [0002] Existing tower cranes are equipped with fixed lighting devices at the rear of the boom at a distance of five to ten meters from the operating room, so that the site conditions can be seen clearly during construction at night. It is often necessary to replace damaged lamp tubes, and the lighting device on the boom is far from the operating room, which is inconvenient to replace, and it is a high-altitude operation, which brings certain dangers to the staff who replace the lighting equipment. On the other hand, when the lifting trolley moves beyond the effective lighting range of the fixed lighting device, the lighting effect will obviously drop, which will affect the work quality and efficiency. Contents of the invention [0003] The purpose of the present invention is to overcome the disadva...
