Problems solved by technology

[0002] The hoisting motor and other parts of the tower crane in the high altitude are prone to failure, and the probability of maintenance is very high. Because these damaged parts are heavy, their disassembly and hoisting are heavy, and the operation is relatively difficult, and there are great risks in the operation at high altitude Potential safety hazard, auxiliary hoisting device is required for auxiliary hoisting
[0003] At present, the auxiliary hoisting device of most tower cranes is a fixed bracket structure, and the more common auxiliary hoisting device is a portal frame structure, which is directly welded to the two main chords of the balance arm through two bracket columns. In hoisting, the position of the portal frame structure is fixed, and it can only be hoisted at a fixed hoisting position, which severely limits the use of auxiliary hoisting devices

Embodiment Construction

[0030] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0031] Such as figure 1 and figure 2 As shown, according to the embodiment of the present invention, the grilling device includes a pillar 10 and a hoisting part 20 rotatably arranged on the pillar 10, the rotation axis of the hoisting part 20 is consistent with the longitudinal extension direction of the pillar 10, and one part of the hoisting part 20 Side suspension is provided with hoisting pulley 21. During hoisting, the hoisting pulley 21 can be placed above the object to be hoisted by rotating the hoisting portion 20 provided on the pillar 10, which is convenient for connection. After the connection is completed, the hoisting part 20 can be rotated to a suitable position, so as to facilitat...

Abstract

The invention provides a tower crane, a derrick mast device and a hoisting method thereof. The derrick mast device comprises a support post (10) and a hoisting part (20) which is rotationally arranged on the support post (10), wherein a hoisting pulley (21) is suspended on one side of the hoisting part (20). According to the derrick mast device disclosed by the invention, flexible adjustment of the derrick mast device in a hoisting process can be realized, hoisting operation is more flexible and convenient, and the adaptability of the derrick mast device is enhanced.

Description

technical field [0001] The invention relates to the field of construction hoisting machinery, in particular to a tower crane, a pick-up pole device and a hoisting method thereof. Background technique [0002] The hoisting motor and other parts of the tower crane in the high altitude are prone to failure, and the probability of maintenance is very high. Because these damaged parts are heavy, their disassembly and hoisting are heavy, and the operation is relatively difficult, and there are great risks in the operation at high altitude Potential safety hazard, auxiliary hoisting device is required for auxiliary hoisting. [0003] At present, the auxiliary hoisting device of most tower cranes is a fixed bracket structure, and the more common auxiliary hoisting device is a portal frame structure, which is directly welded to the two main chords of the balance arm through two bracket columns. In hoisting, the position of the portal frame structure is fixed, and it can only be hois...
