The invention discloses a gantry crane provided with transmission towers in a setting up mode. The gantry crane comprises a gantry crane body. Fixing vertical frames are arranged at the two ends of the gantry crane body, the bottom end of cross beam suspension arm is provided with a sliding rail, and the sliding rail is slidably connected with an electric hoist; the two ends of the upper end surface of the cross beam suspension arm are provided with rotary fixing seats, and the transmission towers are fixedly installed at the upper ends of the rotary fixing seats; the upper ends of the transmission towers are provided with a plurality of bunched wire frames which are formed by support rods and bunched wire winding discs, one ends of the support rods are fixed to the transmission towers, and the other ends of the support rods stretch out of the transmission towers in a supporting mode; and the bunched wire winding discs are fixedly installed at the tail ends of the support rods. In this way, the gantry crane can serve as a gantry crane to stably conduct hoisting work through the steel wire electric hoist and can also set up the transmission towers on the gantry crane body to conduct electric power transmission.
Description
technical field [0001] The invention relates to the field of cranes, in particular to a gantry crane for building power transmission towers. Background technique [0002] The gantry crane is a variant of the bridge crane. In the port, it is mainly used for loading and unloading operations of outdoor cargo yards, stockyard cargo, and bulk cargo. Its metal structure is like a door-shaped frame. Two legs are installed under the main beam, which can directly walk on the track on the ground. The two ends of the main beam can have outrigger cantilever beams. Gantry cranes have the characteristics of high site utilization, large operating range, wide adaptability, and strong versatility, and are widely used in port freight yards. However, the general gantry crane will not carry other tools for work, and the space cannot be used reasonably for redundant work, especially for large tools such as power transmission towers, which cannot be carried on the gantry crane, which reduces th...
