Embodiment Construction

[0013] The present invention will be further described in detail below in combination with specific embodiments.

[0014] Such as diagram 2-1 , Figure 2-2 and Figure 2-3 As shown, a tower crane cable lifting device of the present invention includes a main board 1 , two U-shaped attached boards 2 and two insulating pulleys 4 . The two U-shaped attached plates 2 are fixed on the same side of the main board 1, and the two U-shaped attached plates 2 are fastened with the main board 1 and arranged symmetrically. The opening of the attached plate 2 is basically in the horizontal direction; between each of the U-shaped attached plates 2 and the main board 1 is a mounting part of an insulating pulley 4, such as diagram 2-1 and Figure 2-2 shown.

[0015] Such as diagram 2-1 As shown, on the main board 1 of each installation part, on the surface of the U-shaped additional board 2 opposite to the main board 1, there are inclined slideways 3 with corresponding overlapping posi...

Abstract

The invention discloses a lifting-following device of a tower crane cable. The lifting-following device comprises a main plate, two U-shaped attaching plates and two insulation pulleys, wherein the two U-shaped attaching plates are fixed at the same side of the main plate, and the two U-shaped attaching plates are both buckled with the main plate and are symmetrically arranged and openings of the attaching plates are basically horizontal; installing parts of the insulation pulleys are arranged between the U-shaped attaching plates and the main plate, inclined, opposite and coincident slideways are arranged on the main plate of each installing part and on the board, which is opposite to the main plate, of each U-shaped attaching plate, and the slideways are symmetrically arranged in a reverse V shape; insulation pulleys are arranged in the slideways through pulley shafts, and a space formed between the two pulleys is utilized as a cable channel; and the two sides of the lower end of the main plate are both provided with long-shaped screw rod holes, the two sides of the rear of the main plate are respectively provided with U-shaped bolt hoops, and a horizontal butt strap is arranged between the two U-shaped bolt hoops. The lifting-following device provided by the invention can fix the tower crane cable so that a cable can upward move along the rise of the tower crane, a cable is prevented from being damaged in a lifting process, the lifting efficiency of tower crane equipment is improved, and the lifting-following device is safe and beautiful.

Description

technical field [0001] The invention relates to an auxiliary part of tower crane equipment, in particular to a lifting device for fixing and guiding cables of tower crane equipment. Background technique [0002] In the construction industry, tower crane is an indispensable transportation machinery and equipment. The fixing of tower crane cables is usually very random. Cables sway in the air. It not only makes the lifting of the cable not smooth, but also causes the tower crane to have an unattractive appearance, and at the same time, it is very easy to have potential safety hazards. Especially in a high-rise building, the tower crane has to be raised several times during the construction period. The tower crane rises with the rise of the floor, and the cables on the tower crane also rise accordingly. Therefore, it is required that the cables must be smooth when rising. , because the cable is very long and heavy, it is best to support it in sections to prevent excessive ten...
