Embodiment Construction

[0021] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0022] Such as figure 1 As shown, the present invention provides a method for unloading a load block from a tower crane. In order to avoid the use of auxiliary, independent large-scale lifting equipment that does not belong to the tower crane, such as truck cranes or For other tower cranes, etc., the core idea of ​​the method for unloading the load block from the tower crane provided by the present invention is to use the hoisting wire rope 20 on the tower crane as a mechanism for lifting the load block 10. The height of the truck crane or other tower cranes cannot dismantle the problem of the load block 10. On the other hand, it can avoid dismantling the arm tip of the boom and reduce the risk of unloading the load block.

Abstract

The invention provides a method for unloading a load pulley from a tower crane. The method comprises the following steps: connecting the load pulley with a hoisting steel wire rope on the tower crane, and controlling the releasing or withdrawing of a winch winding end of the hoisting steel wire rope so as to drop or raise the load pulley. According to the method provided by the invention, the hoisting steel wire rope on the tower crane is used for dropping or raising the load pulley without using auxiliary hoisting machinery to hoist the load pulley, so that the smooth operation of unloading the load pulley is guaranteed, the program of detaching the beam tip joint of a cargo beam is omitted, and the operation risk is lowered.

Description

technical field [0001] The invention relates to the field of tower cranes, in particular to a method for unloading a load block from a tower crane. Background technique [0002] When the tower crane is in working condition, turn the tower crane to a proper position. Run the trolley up to the jib tip. Remove the hook, hoisting wire rope, and luffing wire rope. Use a truck crane (or other tower crane) to remove the tip of the jib arm, and then use a truck crane (or other tower crane) to assist in sliding out the trolley and place it on the ground (or building). After the trolley is repaired or directly install the new trolley on the jib, finally install the tip of the jib arm, hoisting wire rope, and luffing wire rope. [0003] The dismantling process of the above-mentioned trolley needs lifting equipment such as truck cranes or other tower cranes. If the working height of the tower crane exceeds the working height of the truck crane or other tower cranes, it is impossible...
