Problems solved by technology

In the process of adding and lowering joints, the entire weight of the upper part of the tower crane is supported on the jacking device for a long time, which requires high standard operation of the adding and lowering personnel, and casualties are prone to occur
[0003] In addition, the concentration of mass on the top of the tower crane makes the overall center of gravity of the tower crane high and the stability is poor, and the lifting arm and balance arm are exposed to large wind areas, which will generate a large overturning moment on the tower body under the action of strong winds, which may easily cause the overall tower crane to overturn under strong winds

Embodiment Construction

[0030] The present invention will be further described below in conjunction with specific examples and accompanying drawings.

[0031] Such as Figure 1 to Figure 4 As shown, a safe tower crane includes a tower body standard section 1, a slewing structure, a lifting arm 3, a balance arm 4 and a lifting device; the tower body standard section 1 is detachably connected from bottom to top to form a tower body, and the tower body The number of body standard sections 1 can be increased or decreased according to actual needs. The overall lifting is realized by the lifting device.

[0032] The slewing structure includes an inner ring 22 and an outer ring 21 that are rotatably connected, and the inner ring 22 is sleeved on one of the tower body standard sections 1 and is detachably connected with the tower body standard section 1; the boom 3 and the balance arm 4 are respectively fixedly connected with the outer ring 22, so that the boom 3, the balance arm 4 and the slewing structur...

Abstract

The invention provides a safety tower crane and an implementation method thereof. Tower body standard sections are detachably connected from bottom to top to form a tower body, a rotary structure comprises an inner ring and an outer ring which are rotationally connected, and one tower body standard section is sleeved with the inner ring; and a cargo boom and a balance arm are fixedly connected with the outer ring, and the cargo boom, the balance arm and the rotary structure form a whole. The crane further comprises a lifting device, and overall lifting is achieved through the lifting device. According to the safety tower crane, the mutual influences of tower crane section increase and decrease operation and cargo boom and balance arm lifting operation are effectively reduced, and the safety of the tower crane is improved.

Description

technical field [0001] The invention belongs to the technical field of tower cranes, and in particular relates to a safe tower crane and an implementation method thereof. Background technique [0002] Tower cranes, referred to as tower cranes, are widely used in the construction industry as important vertical transportation equipment. In order to meet the construction requirements of ever-increasing building heights, self-elevating tower cranes that can be added are mostly used on the construction site. The slewing mechanism of this type of tower crane is close to the top, and the lower part of the slewing mechanism is equipped with an outer jacket frame and a jacking cylinder. Through the expansion and contraction of the jacking cylinder, the outer frame and the upper tower crane can be lifted up and down, and the standard section of the tower crane can be increased or decreased at the same time. In the process of adding and lowering joints, the entire weight of the upper ...
