Embodiment Construction

[0020] The present invention will be further described in detail below in combination with specific embodiments.

[0021] Such as diagram 2-1 , Figure 2-2 with 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 with Figure 2-2 shown.

[0022] 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 po...

Abstract

The invention discloses a tower crane cable lifting following device. The device comprises a main board, two U-shaped attached boards and two insulating pulleys, wherein the two U-shaped attached boards are fixed on the same side of the main board, buckled with the main board, symmetrically arranged, and provided with openings basically in the horizontal direction; the installation part of each insulating pulley is arranged between each U-shaped attached board and the main board; inclined, opposite and overlapped slide rails are arranged on the main board of each installation part, and the surfaces of the U-shaped attached boards opposite to the main board in a splayed symmetrical arrangement mode; each insulating pulley is arranged in each slide rail through a pulley shaft; a space formed between two pulleys is taken as a cable channel; the two sides of the lower end of the main board are provided with long screw holes; the two sides of the rear surface of the main board are providedwith a U-shaped bolt hoop respectively; and a horizontal lap board is arranged between two U-shaped bolt hoops. A tower crane cable is fixed, so that the cable can smoothly move upwards with the lifting of a tower crane, the cable is prevented from being damaged in the lifting process, the lifting efficiency of tower crane equipment can be improved, and the device is safe and attractive.

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...
