Problems solved by technology

[0006] However, the overall height of the main support arm is relatively high. Once the impact of strong wind is encountered, the cable will sway with the wind, and the outer wall of the cable will repeatedly collide with the main support arm, which will affect the actual service life of the cable and cause the actual use stability of the tower crane. lower

Abstract

The invention discloses a tower crane and a cable connection method thereof. The key points of the technical scheme of the invention are as follows: the tower crane comprises a main supporting arm anda cable; the upper end of the main supporting arm is provided with a cab; a crane boom and a balance arm are connected to the two ends of the cab respectively; the balance arm is provided with a hanging head; one end of the cable is connected to control equipment in the cab; the main supporting arm comprises vertical supporting rods and slippage pieces; a reinforcing rod is connected between twoadjacent vertical supporting rods; the rod wall of each vertical supporting rod is provided with a first chute; each slippage piece comprises a plurality of connection rods and a plurality of first slippage blocks; a hinging point between two adjacent connection rods is a first hinging point; each connection rod is provided with a communication channel in a penetrating manner; and the first hinging points are hinged to the first slippage blocks in a one-to-one correspondence manner. By adopting the tower crane provided by the invention, an operator needs to stay in the cab only, so that operation is simple and convenient, and the safety is high; after the whole mounting is finished, the cable is connected to the vertical rods through the slippage pieces, and stable fixing effect can be generated to the cable.

Description

technical field [0001] The invention relates to the technical field of hoisting devices, in particular to a tower crane and a cable connection method thereof. Background technique [0002] Tower cranes are widely used in my country's construction industry. [0003] A traditional tower crane structure, such as a Chinese utility model with monitoring number CN202609839U, includes a vertically arranged main support arm, the lower end of which is fixed on the ground, and the upper end of the main support arm is connected with a driver's cab. There are lifting arms and balance arms on the left and right sides of the room, and a suspension head is also set on the balance arms. [0004] The operator sits in the cab and controls the circumferential rotation of the main support arm, the boom and the forward and backward movement of the lifting head to achieve the hoisting effect. [0005] In the traditional tower crane structure, the control center is located in the cab, and multip...
