Abstract

The invention discloses a single-boom gantry crane amplitude-variable compensation system and a single-boom gantry crane. The amplitude-variable compensation system comprises a lifting winding drum, an amplitude-variable compensation winding drum, a first compensation steel wire rope, a second compensation steel wire rope and an amplitude-variable steel wire rope, wherein the lifting winding drum and the amplitude-variable compensation winding drum are arranged on the turntable; the first compensation steel wire rope twines together with a first compensation pulley block and a pulley of a first lifting hook pulley block; the second compensation steel wire rope twines together with a second compensation pulley block and a pulley of a second lifting hook pulley block; two ends of the first compensation steel wire rope and the second compensation steel wire rope are respectively connected with the lifting winding drum and the amplitude-variable compensation winding drum; the first compensation steel wire rope and the second compensation steel wire rope, which are mutually symmetrical, are used for maintaining the balance of a lifting hook; the amplitude-variable steel wire rope is used for sequentially winding the first amplitude-variable pulley block and the second amplitude-variable pulley block; two ends of the amplitude-variable steel wire rope are connected with the same side of the amplitude-variable compensation winding drum, so that the amplitude-variable steel wire rope and the amplitude-variable compensation winding drum simultaneously wind in and out.

Description

technical field [0001] The invention relates to the technical field of single-arm portal cranes, in particular to a single-arm portal crane. Background technique [0002] The single-arm portal crane is a kind of lifting equipment that is relatively common in production sites such as port loading and unloading and shipyard hoisting, and plays an important role in production operations. [0003] figure 1 It is a schematic diagram of the amplitude compensation system of an existing single-arm gantry crane, such as figure 1 As shown, the compensating drum 110 and the luffing drum 111 are arranged on the turntable of the single-arm portal crane. The two compensating pulley blocks are arranged symmetrically relative to the jib. A part of the pulley 201 of a compensating pulley set is arranged at the head of the gable frame of the single jib portal crane, and the other part of pulleys 203 and 205 are arranged at the head of the jib. A part of the pulley 202 of another compensat...
