Embodiment Construction

[0022] The present invention will be further described below in conjunction with accompanying drawing.

[0023] The present invention is a hoisting and arranging device that can be installed and disassembled as a whole, such as figure 2 As shown, the overall structure is located between the two cross-web bars of the gable frame, including the lifting pulley 1, the long axis 7 of the lifting pulley running through its center, and two side plates 4 respectively connected to the two ends of the long axis 7 of the lifting pulley The lifting pulley 1 is no longer limited by the spacer in the prior art, and can move axially along the major axis 7 of the lifting pulley, thereby realizing the function of arranging ropes.

[0024] In addition, in order to facilitate the installation and connection between the two ends of the long axis 7 of the lifting pulley and the side plate, the side plate 4 is provided with mounting holes that match the ends of the long axis 7 of the lifting pulle...

Abstract

The invention discloses an integral-installation lifting rope-arranging structure of a movable-arm tower type crane. A lifting rope-arranging device which can be integrally disassembled is arranged in a herringbone frame structure and comprises a lifting-pulley long shaft and a lifting pulley sheathed on the lifting-pulley long shaft, wherein the lifting pulley can move axially without limitation of the long shaft to realize a rope-arranging function. The integral-installation lifting rope-arranging structure disclosed by the invention has the advantages that the problem that the abrasion of a steel wire rope and the lifting pulley is severe because the installation space for a balance arm of the movable-arm tower type crane is small and the rope-arranging device cannot be arranged on a lifting mechanism is solved, and the guiding function and the rope-arranging function can be realized simultaneously; and the whole device can be connected between two horizontal web members of a herringbone frame by side plates at the two ends of the lifting-pulley long shaft in a detachable manner, so that the disassembly and the installation are convenient.

Description

technical field [0001] The invention relates to a hoisting and arranging rope structure, which is especially suitable for integral installation on a boom tower crane. Background technique [0002] The lifting mechanism of the balance arm of the jib tower crane generally has a small space. Due to the limitation of the installation space of the balance arm, it is basically impossible to directly install the lifting and arranging device on the existing lifting mechanism; , only the lifting pulley is installed on the herringbone frame, this lifting pulley can only play a guiding role, and does not play the role of rowing ropes, and this structure wears a lot to steel wire rope and lifting pulley. [0003] Such as figure 1 As shown, the existing lifting pulley device is composed of five parts, which are respectively a vertical plate (11), a lifting pulley (12), a shaft end baffle (13), a pulley shaft (14) and a spacer ( 15); two relatively parallel vertical plates (11) are weld...
