The invention discloses an anti-explosion electric single beam crane. The anti-explosion electric single beam crane comprises an anti-explosion electric block, a metal structure bridge frame and a cart running mechanism; fixing supports are arranged at the two ends of the metal structure bridge frame, the cart running mechanism is arranged on the fixing supports, and a guide rail is installed at the bottom end of the metal structure bridge frame; the upper end of the anti-explosion electric block is connected to the guide rail in a sliding manner through installation of a pulley body, and the cart running mechanism and the anti-explosion electric block are each provided with an anti-explosion electric control system; and the bottom end of the metal structure bridge frame is further provided with an electric block protection support, the electric block protection support is provided with a plurality of waved fulcrum bars connected in an intersected manner, and small pulleys are arranged at the positions of intersecting points of the fulcrum bars in a connected manner and are connected to the guide rail in a sliding manner. By means of the above manner, the stability of the crane can be guaranteed, the waved electric block protection support is connected to one end of the anti-explosion electric block, and the stretching stress of the anti-explosion electric block is improved.
Description
technical field [0001] The invention relates to the field of cranes, in particular to an explosion-proof electric single-girder crane. Background technique [0002] Explosion-proof cranes, that is, explosion-proof hoist bridge cranes, are cranes with explosion-proof electric hoists as the lifting mechanism. The technology is mature and reliable, the structure is simple, the shape is small, the weight is light, and the installation, use and maintenance are convenient. Environmental conditions: The working power supply is three-phase AC, the rated frequency is 50HZ, and the rated voltage is 380V; the working environment temperature is -20~40℃. When working indoors at 40°C, the relative humidity should not exceed 50%, and when working outdoors at 25°C, the relative humidity is allowed to be as high as 100% for a short time. The altitude of installation and use shall not exceed 2000m. It is suitable for maintenance and loading and unloading work in machinery workshops, wareho...
