Problems solved by technology

During the use of the tower crane, the installation wire rope moves with the boom. Due to the influence of various factors such as the gravity of the wire rope and the environment, the distance between the two connection points changes continuously with the movement of the boom. It is easy to interfere and get entangled with other parts of the tower crane, seriously affecting the safety of the tower crane

Embodiment Construction

[0010] The present invention will be further described below in conjunction with accompanying drawing.

[0011] Such as figure 2 with image 3 As shown, the present invention comprises installation steel wire rope 2, pulley block 4, counterweight group 5; Described pulley block 4 comprises certain pulley and a moving pulley; One end of described installation steel wire rope 2 is fixed on the jib 1, and the other end passes through fixed pulley and The movable pulley is connected to the top of the tower 3, and the counterweight 5 is connected to the movable pulley. The gravity of the counterweight 5 is used to tighten the installation wire rope 2 suspended between the boom and the tower top, so that the installation wire rope 2 is connected between the boom 1 and the tower top 3. The part in between is not concave.

[0012] In the above-mentioned embodiment, it is also possible to add a plurality of fixed pulleys to arrange and install the steel wire rope 2 according to the ...

Abstract

The invention discloses a mounting steel wire rope of a mobile type movable arm tower crane. The mounting steel wire rope comprises a mounting steel wire rope, a pulley block and a counterweight group, wherein the pulley block comprises at least one fixed pulley and a movable pulley; one end of the mounting steel wire rope is fixed on a cargo boom, and the other end of the mounting steel wire rope is connected with a tower top through the fixed pulley and the movable pulley; and the counterweight group is connected on the movable pulley. When the steel wire rope hung between the cargo boom and the tower top is tightened, the situation that the mounting steel wire rope and the structure intervene can be effectively avoided during the using process.

Description

technical field [0001] The invention relates to a movable jib tower crane installation steel wire rope, especially suitable for the jib tower crane. Background technique [0002] The installation wire rope refers to the wire rope that connects the boom and the top of the tower to ensure that the boom is in a specific state during installation and maintenance of the boom tower crane. The steel wire rope installed in the current jib tower crane is fixed at both ends on the boom and the top of the tower respectively, such as figure 1 As shown, the two ends of the installation wire rope are connected to the boom and the top of the tower with pins (bolts) respectively. The length of the wire ropes at the two connection points on the boom and the tower top remains unchanged. During the use of the tower crane, the installation wire rope moves with the boom. Due to the influence of various factors such as the gravity of the wire rope and the environment, the distance between the t...
