Embodiment 1

[0059] This embodiment is an anti-skip rope device for horizontal wire ropes in a tower crane, which is installed at the steering pulley block 1 in the traveling trolley of the tower crane; figure 2 Shown is a diverting pulley block 1 for converting the direction of wire rope extension from vertical to lateral. The anti-skip rope device can prevent the wire rope from skipping or fraying in this place.

[0060] like image 3 As shown, the steering pulley block 1 on which the anti-skip rope device is installed includes a fixed pulley 11 , an axle 13 and a clamping plate 12 clamped on both sides of the fixed pulley 11 . The wheel body of the fixed pulley 11 includes a first rope groove 110 for accommodating the wire rope in the circumferential direction. The cross section of the first rope groove 110 is in the shape of a "normal distribution curve" with an upward opening, and the bottom of the first rope groove 110 is a semicircle matching the outer contour of the wire rope. ...

Abstract

The invention belongs to the field of mechanical equipment, and particularly relates to a rope skipping prevention device for a horizontal steel wire rope in a tower crane and an assembling method thereof. The rope skipping prevention device comprises a rope skipping prevention pulley block and an adjustable connecting frame. The rope skipping prevention pulley block comprises a special wheel shaft, a limiting pulley and two groups of round nuts. The middle section of the special pin shaft is a polished rod section used for being sleeved with the limiting pulley. Threaded sections are arranged at the two ends of the polished rod section in the special wheel shaft and used for being sleeved with round nuts. An annular limiting part which protrudes outwards and has a double-hump-shaped section is arranged in the circumferential direction of a pulley body of the limiting pulley; second rope grooves are formed in the centers of the limiting parts. The limiting part can be inserted into the first rope groove, and a kidney-hole-shaped cavity used for containing a steel wire rope is formed between the first rope groove and the second rope groove. The adjustable connecting frame is used for connecting the rope skipping prevention pulley block and the steering pulley block and adjusting the installation distance between the two pulley blocks. The problems that the steel wire rope of an existing tower crane is prone to rope skipping faults, so that the steel wire rope is broken, and pulley blocks are damaged are solved.

Description

technical field [0001] The invention belongs to the field of mechanical equipment, and in particular relates to an anti-skip rope device for a horizontal wire rope in a tower crane and an assembling method thereof. Background technique [0002] Tower crane is a common construction hoisting equipment. During the operation of tower crane hoisting heavy objects, the hoisting wire rope will pass through the walking trolley and shuttle between multiple steering pulleys on the walking trolley; the walking trolley can realize hoisting position transformation. During the lifting and lowering process of the hoisting object, the wire rope will telescopically move in each steering pulley, and the wire rope is located in the rope groove in the pulley block. [0003] When the tower crane performs tasks such as lifting heavy objects, rotating and reversing the boom, and quickly switching the lifting speed, the steel wire rope may swing in various directions such as left and right, front ...
