Embodiment
[0021] Example: such as figure 1 , 2 As shown, this embodiment specifically relates to a gantry crane that can walk and work on a ramp. The gantry crane is mainly composed of two sets of traveling carts 4 at the bottom and a leg structure 3 arranged on the traveling cart 4. , the main beam 1 that laterally connects the outrigger structures 3 on both sides and the lifting trolley 2 arranged on the main beam 1; wherein the outrigger structures 3 on each side are composed of fixed outriggers 31 located at the high position of the ramp and fixed legs 31 located at the low position of the ramp. The fixed outrigger 31 and the telescopic outrigger 32 can be adjusted within the slope rate range allowed by the height difference, and the size can be adjusted steplessly, accurate to mm level, to ensure that the gantry crane is always level state.
[0022] Such as Figure 4 , 5 As shown, the traveling cart 4 at the bottom of the gantry crane adopts a double-rail form, which is specifi...

The invention belongs to the field of hoisting and lifting machinery, and particularly relates to a portal crane capable of travelling and operating on a ramp. The portal crane comprises a left travelling cart, a right travelling cart, landing leg structures arranged on the travelling carts, main beams and a hoisting crab arranged on the main beams, wherein the landing leg structures particularly comprise fixed front and rear landing legs and telescopic landing legs that are arranged along the longitudinal ramp; hydraulic oil cylinders are arranged at the bottoms of the telescopic landing legs and particularly used for adjusting heights of the landing leg structures on the ramp, and keeping the landing leg structures in horizontal states; and cross shafts are arranged at the bottoms of the landing leg structures, so that the landing leg structures are in vertical states. The portal crane has the advantages that the portal crane can be in the horizontal state and the vertical state on the ramp all the time through adjustment of the hydraulic oil cylinders and the cross shafts, a ramp adjustment foundation is not required to be constructed, or the height and weight of the ramp adjustment foundation can be reduced greatly, the construction is simplified, the cost is saved, and the construction progress is accelerated.
Description
technical field [0001] The invention belongs to the field of hoisting and hoisting machinery, and in particular relates to a gantry crane capable of walking and operating on a ramp. Background technique [0002] The gantry crane is a kind of deformation of the bridge crane, which is mainly used for loading and unloading operations of outdoor cargo yards, material yards, and bulk cargo. Its metal structure is like a door-shaped frame. Two outriggers 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. [0003] Gantry cranes have the characteristics of high site utilization, large operating range, wide adaptability, and strong versatility, so they are widely used in port freight yards; at the same time, they are also widely used in construction sites for erecting beams and hoisting heavy equipment etc., but the existing gantry cranes are all designed to be used on a plane, and...
