Especially in winter and summer, a driver of the tower crane can feel very painful when climbing the tower crane. The manpower of tower crane drivers is greatly consumed, and the working state and the working efficiency of the tower crane drivers are seriously influenced, so that the manned lifting device of the tower crane is provided.

The utility model provides a technical scheme that technical problem adopted is: a manned lifting device of a tower crane comprises: the standard festival, the standard festival comprises four main limbs and some crossbeams, four cushion blocks have been welded to main limb inboard, the welding has the guide rail to support on the cushion block, the guide rail supports and is equipped with two, and the symmetric distribution is at standard festival medial surface, be equipped with the guide rail on the guide rail supports, the guide rail is equipped with two, welds with the crossbeam contact surface that two guide rails supported respectively, the guide rail inboard is seted up flutedly, and the recess passes through the assembly pulley with manned platform and is connected. The standard knot is externally provided with a sleeve frame which is provided with a sleeve frame upper-layer platform and a sleeve frame lower-layer platform. Two winches are symmetrically arranged on the upper platform of the sleeve frame.

Preferably, the two winches are fixed on two sides of the upper platform of the sleeve frame and arranged at an included angle of 90 degrees with the guide rail, steel wire ropes of the winches penetrate through ear plates of the manned platform to be fixed, and the manned platform can be controlled to move up and down through a remote controller.

Preferably, toughened glass is adopted at manned platform bottom, safety barrier is equipped with around manned platform, manned platform both sides face is equipped with the otic placode.

Preferably, four cushion blocks are arranged at the bottom of the guide rail support and welded with the standard joint main limbs, an adjusting square steel is welded on each cushion block, and the adjusting square steel is welded on a guide rail support surface.

The utility model has the advantages of it is following:

firstly, two winches with synchronizers are arranged, steel wire ropes penetrate into lifting lugs on two sides of a platform, and a remote controller is used for controlling the manned platform to move up and down. The tower crane driver saves physical power and time, is convenient and quick, and can also increase the working efficiency.

Secondly, the joint of the guide rail adopts a bolt connection mode, so that the installation and the disassembly of the standard knot are not influenced. The existing standard knot can be used by simple transformation.

The platform and the ladder stand inside the existing standard knot can be saved, steel is greatly saved, and the cost of the standard knot is reduced.
