Embodiment 1

[0027] Such as figure 1 and figure 2 As shown, a rope supporting device for a tower crane includes a wheel 1, a support frame 2, a traction pulley 3 and a rope pulley 4, the support frame 2 is provided with three layers, and the wheels 1 are arranged on four layers of the upper layer of the support frame 2. On the first corner, the traction roller 3 is arranged on the left and right sides of the middle layer of the support frame 2, and the rope pulley 4 is arranged in the middle of the bottom layer of the support frame 2, and the wheels 1, the traction roller 3 and the rope pulley 4 are provided with The direction of rotation is the same. The rope supporting device can stably support the drooping steel wire rope, and can also ensure the smooth passage of the lifting trolley. High stability and low failure rate. To achieve the reduction of the negative impact of the hoisting wire rope sagging on the effective use of the height space and the performance of the tower crane br...

Embodiment 2

[0032] A tower crane supporting lifting system, comprising a hoisting mechanism 5, a hoisting wire rope 6, a rope supporting device 7, a luffing mechanism 8, and a lifting trolley 9, and the luffing mechanism 8 is provided with a luffing wire rope 10 passing through And connect the supporting rope device and the hoisting trolley, the hoisting wire rope 6 passes through the hoisting mechanism and the supporting rope device in turn to connect with the lifting trolley 9, and the steel wire ropes on both sides of the lifting trolley 9 are symmetrically arranged. The rated lifting weight of the tower crane is the total amount of the hook and the lifting objects. When the rope support device is installed, the hook only needs to meet the strength requirements for lightweight design to improve the actual performance of the tower crane.

[0033] The hoisting wire rope 6 passes through the rope pulley in the rope supporting device, and lifts the drooping lifting wire rope through the rop...

Abstract

The invention discloses a tower crane rope supporting device. The tower crane rope supporting device comprises wheels, a supporting frame, traction pulleys and a rope supporting pulley. The supporting frame is provided with three layers, the wheels are arranged at the four corners of the upper layer of the supporting frame, the traction pulleys are arranged on the left side and the right side of the middle layer of the supporting frame in a sliding mode, the rope supporting pulley is arranged in the middle of the bottom layer of the supporting frame, and the rotation directions of the traction pulleys and the rope supporting pulley are consistent. The tower crane rope supporting device is durable, does not interfere with the operation of a crane carriage, and solves the negative influence of the drooping of the steel wire rope on the performance of a tower crane.

Description

technical field [0001] The invention relates to the technical field of tower crane auxiliary equipment, in particular to a tower crane rope support device. Background technique [0002] Tower crane, that is, tower crane, is a kind of hoisting equipment used in building construction. The hoisting wire rope is the equipment for the tower crane to lift objects and transmit power. The reel starting from the lifting mechanism on the balance arm of the tower crane is wound on the pulley block of the lifting trolley and the hook, and fixed at the end of the boom. When the trolley runs to the far end of the jib, the wire rope hangs too long, and the wire rope will sag due to its own weight. At present, with the continuous increase of construction projects of high-rise large buildings, large and super large tower cranes have also become mainstream products in the current market. Large and ultra-large tower cranes have relatively long booms, reaching 80 meters, and the diameter of t...
