Embodiment Construction

[0009] An improved tower crane buttress pole removal device, as attached figure 1 As shown, the tower crane balance arm main beam 1 is included, the lower end of the boom 5 is hinged with the lower end of the boom support frame 4 and fixedly arranged on the tower crane balance arm main beam 1, and the boom support frame 4 The upper end of the boom rod 3 is hinged with the lower end of the boom rod 3, and the upper end of the boom rod 3 is hinged with the upper end of the boom 5. The top of the boom 5 is provided with a pulley 7 at the top of the boom, and the wire fixed pulley 11 is fixed on the main girder 1 of the balance arm of the tower crane, and the steel rope 8 is connected with the fixed pulley 11 of the wire, the pulley 7 at the top of the boom and the movable pulley 9 of the hook through the hoist 2 set on the main girder 1 of the balance arm of the tower crane. The tail end of steel rope 8 is fixed on the upper end of boom 5. Below the hook movable pulley 9, the li...

Abstract

The invention belongs to the field of tower type cranes for buildings, and in particular relates to an improved sustaining wall rod dismantling device of a tower type crane, which comprises a tower type crane balance arm main beam, wherein the lower end of a jib loading boom is hinged with the lower end of a jib loading boom support frame together and is fixedly arranged on the tower type crane balance arm main beam, the upper end of the jib loading boom support frame is hinged with the lower end of a jib loading boom pull rod together, the upper end of the jib loading boom pull rod is hinged with the upper end of the jib loading boom together, the top end of the jib loading boom is provided with a jib loading boom top end pulley, a wire fixed pulley is fixedly arranged on the tower type crane balance arm main beam, a steel rope is connected with the wire fixed pulley, the jib loading boom top end pulley and a lifting hook movable pulley together, and the jib loading boom support frame and the jib loading boom pull rod regulate the hoisting angle of the jib loading boom through a regulating pulley mechanism. By using the improved sustaining wall rod dismantling device, no limit by rotation of the jib loading boom exists, a sustaining wall rod can be dismantled after the improved sustaining wall rod dismantling device is installed in a proper position, thus potential safety hazards of incline pulling and incline hoisting of the tower type crane are eliminated.

Description

technical field [0001] The invention belongs to the field of tower cranes used in construction, and in particular relates to an improved dismantling device for a buttress pole of a tower crane. Background technique [0002] At present, the dismantling of the supporting wall pole of the tower crane is carried out by the main hoisting mechanism of the tower crane itself. There is no special device for dismantling in the equipment delivered by the manufacturer. It can be rotated freely and can be easily disassembled. The tower crane cannot rotate the remaining few buttresses during disassembly, and cannot reach the ideal hoisting position. This will increase the difficulty of disassembly, and there must be cable-stayed and inclined The situation of hanging has increased the danger of the operation and the probability of safety accidents. Contents of the invention [0003] The technical problem to be solved by the present invention is: when the tower crane removes the buttr...
