Embodiment Construction

[0025] The present invention will be further supplemented with description below in conjunction with the accompanying drawings and specific embodiments.

[0026] As shown in Fig. 1 and A-A, B-B sectional view of Fig. 1, promptly Fig. 2, shown in Fig. 3, the implementation of the present invention is to form the suspension main frame structure by web 1, end plate 2, top plate 3, bottom plate 4, and according to above-mentioned The reinforced structure of the hanging row is strengthened. On this basis, pulley 25 and pulley shaft 9 are installed. Single pulley 5 is installed in both sides, is single pulley train 11, sees the A-A sectional view of Fig. 1. Double pulley is installed in the middle, is double pulley train 10, sees the B-B sectional view of Fig. 1. During work, the hanging row is installed and connected with the suspension hook 8 by the lifting trunnion 7, and the wire rope is installed on the pulleys 5, 25. According to the difference of the working conditions, the...

Abstract

The invention relates to one kind of device with hangs row, especially involves one kind of shipbuilding profession gantry crane special-use equipment. This hangs row equipment take hangs row as main structure, the pulley system, strengthen structure and the connection partially composes, as hangs the row as main structure with the web plate, which can carry the board, the roof, the ledger wall, double pulley in the axis ear the welding becomes; As the pulley system with the pulley, copper sheathing, the small semicircle wrap, the small circle wrap, the slippery wheel axle, steel lagging, bolt, oil cup which becomes the installment , including double pulley which is systematic and the single pulley system; As hangs the row strengthen structure with big humeral scute, above the auricle liner, the big muscle board, the center muscle board, the small muscle board, which compose of small scale board, big scale board, welds the pad, ear scale board; Hangs row with hangs hook is connect departially by hanging the axis, the spacing pad, check washer, the small circle nut composes. The pulley effectively slows down steel role's attrition; When lifts, the steel role's stress obtains the optimization first.

Description

technical field [0001] The invention relates to a lifting device, in particular to a special hoisting and rowing device for a gantry crane in the shipbuilding industry. Background technique [0002] The hoisting equipment is a special equipment for the gantry crane used for lifting, which can increase the lifting points and optimize the force of the wire and cable. [0003] Ship products need to be divided into sections during the construction process, and then assembled. During the construction of the sections, it is necessary to shift and turn over, and such work needs to be completed by cranes. In order to make the segmented lifting and turning over safe and reliable, it is necessary to set up a number of lifting points reasonably. In order to ensure that the steel wire rope is correctly connected to the lifting point and the lifting equipment, it is necessary to install a lifting device.
