Improved sustaining wall rod dismantling device of tower type crane

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.

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: when the tower crane removes the buttress pole, it is not restricted by the rotation of the boom, and the buttress pole can be disassembled after being installed at a suitable position, eliminating the need for cable-stayed and inclined-hanging of the tower crane. security risks
