Abstract

The invention discloses a gantry structure of a portal crane. The gantry structure of the portal crane comprises a portal and a cylinder, wherein the cylinder is mounted on the portal; the portal is formed by welding a portal cross beam and a portal end beam; a plurality of cylinder reinforcing rib plates are welded in the cylinder at intervals in the height direction; a plurality of cylinder climbing ladders are arranged outside the cylinder; a cylinder protecting fence is arranged above a position, corresponding to each cylinder climbing ladder, on the cylinder; a ladder platform is arranged at the upper part of the cylinder; a platform protecting fence is arranged on the ladder platform; a portal ladder connected to the lowermost cylinder climbing ladder is arranged on the portal. The gantry structure of the portal crane has the advantages of stable structure, high reliability, large carrying force and convenience in daily maintenance and repair.

Example Embodiment

[0016] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0017] see figure 1 and figure 2 As shown, in this embodiment, a door frame structure of a portal type crane includes a door seat and a cylinder body 1, the door seat is welded by a door seat beam 2 and a door seat end beam 3, and the cylinder body 1 is fixed on the door seat beam 2, and several door seat reinforcing rib plates 4 are welded and fixed inside the door seat beam 2 and the door seat end beam 3. Inside the cylindrical body 1 are welded several pieces of cylindrical reinforcement ribs 5 at intervals along the height direction, and several cylindrical climbing ladders 6 are arranged outside the cylindrical body 1, and the several cylindrical climbing ladders 6 are staggered and fixed. Outside the cylinder 1, a connecting platform is provided between two adjacent cylinder climbing ladders 6 . And corresponding to each cylinder crawling ladder on the described cylinder 1, a cylinder guardrail 7 is arranged above it.

[0018] A ladder platform 8 is arranged on the upper part of the cylindrical body 1 , and several ladder platform reinforcing ribs 9 are welded between the bottom of the ladder platform 8 and the cylindrical body 1 . And the ladder platform 8 is provided with a platform guardrail 10, and the door seat is provided with a door seat ladder 11 connected to the cylinder crawling ladder 6 at the bottom.

[0019] A connecting flange 12 is welded on the upper end of the cylindrical body 1 , and several flange ribs 13 are welded between the bottom of the connecting flange 12 and the cylindrical body 1 .

[0020] The above embodiments have only set forth the basic principles and characteristics of the present invention, the present invention is not limited by the above-mentioned examples, and on the premise of not departing from the spirit and scope of the present invention, the present invention also has various changes and changes, and these changes and changes all fall within the scope of the claimed invention. The protection scope of the present invention is defined by the appended claims and their equivalents.
