Detailed Description

In order to make the technical scheme of the invention clearer and clearer, the invention is further described with reference to the accompanying drawings, and any scheme obtained by carrying out equivalent replacement and conventional reasoning on the technical characteristics of the technical scheme of the invention falls into the protection scope of the invention.

A gantry crane with a small steel structure comprises a beam 1, a left force arm 2, a right force arm 3 and a lifting system 4, wherein the beam 1 is made of I-shaped steel and serves as a bearing main body, the left force arm 1 and the right force arm 2 are made of channel steel, and a traveling system 5 is arranged below the left force arm 2 and the right force arm 3; a track 6 is arranged below the left force arm and the right force arm; the cross beam 1, the left force arm 2 and the right force arm 3 are welded into a gantry shape, and rib plates are arranged at the welding positions of the cross beam 1, the left force arm and the right force arm; the fixing device is used for playing a better fixing role; a hoisting hole 7 is formed in the cross beam 1; 2-4 hoisting holes are formed in the number and are used for installing, dispatching and transporting the gantry crane; a slide wire is arranged on the cross beam and arranged along the length direction of the cross beam; the slide wire is provided with a lifting system 4 in sliding fit with the slide wire; the left force arm 2 and the right force arm 3 are both provided with a connecting rod 12; the left force arm and the right force arm are fixed to achieve a better bearing effect.

The walking system 5 can move along a track, the walking system 5 comprises walking wheels 8, a fixing shaft 9 and a supporting shell 10, the fixing shaft 9 is arranged in the supporting shell 10, and the walking wheels 8 are arranged on the fixing shaft 9; the travelling wheels are movable along the rails; the track 6 is provided with an embedded part 11 to improve the strength and the bearing capacity of the track;

furthermore, the traveling system is also provided with a locking mechanism matched with the traveling wheels, and when the traveling system needs to move, the traveling system moves along the track through the traveling wheels; when need not to remove, locking mechanism with the walking wheel locking can.

The lifting system 4 comprises an electric hoist; the electric hoist comprises a lifting hook, a rope connected with the lifting hook, a motor for driving the rope to ascend and descend, and a control system connected with the motor. The electric hoist can transversely move along the length direction of the slide wire; the material can be hoisted through the electric hoist, so that the hoisting efficiency is ensured; the electric hoist can slide along the slide wire in a translation way, and can play a role in translating heavier objects, thereby avoiding the movement of pure manual carrying.

The maximum translation distance of the electric hoist along the horizontal direction is 8 m; the maximum distance of movement in the vertical direction is 4 m; the load bearing capacity of the beam is 1-2 tons.
