Description

Portable internal climbing tower crane spandrel girder hoisting device

Technical Field

The utility model belongs to the technical field of construction machinery, concretely relates to tower crane spandrel girder hoisting device is climbed in portable.

Background

The inner climbing tower crane is a tower crane installed in an elevator shaft or a staircase in a building, and can climb upwards gradually along with the construction process. Because the internal climbing tower crane is arranged in the middle of the building, the internal climbing tower crane does not occupy the construction site and has small amplitude of extending out of the building, is suitable for the engineering with narrow site and can effectively avoid surrounding obstacles, sidewalks and the like; tracks do not need to be laid, and a reinforced concrete foundation does not need to be specially manufactured, so that construction preparation is simple (holes only need to be reserved), and cost is saved; the construction requirements can be met only by a small number of standard sections without a plurality of anchoring devices and complex attachment operation, the one-time investment is low, and the economic benefit is remarkable. Therefore, the internal climbing tower crane can be widely applied to the construction of high-rise buildings.

The climbing of the tower crane is the key work of super high-rise construction, and the climbing process of the tower crane requires the aerial disintegration of a bearing beam of the tower crane, the transportation to a preset floor and the installation, thereby realizing the climbing of the tower crane. As shown in fig. 1, the lifting of the traditional bearing beam needs to be performed by means of other nearby tower cranes for matched construction, and because the lifting of the bearing beam is performed in a high altitude and narrow space, not only are operators without reliable protective measures and the operation complicated, but also the collision risk between the tower cranes is large during the operation, the high falling risk in the lifting process is large, and the whole operation process has large potential safety hazards; in addition, the promotion of traditional spandrel girder needs about 2 hours, and the tower crane that climbs and cooperate the tower crane can not carry out normal hoist and mount work during whole promotion operation, greatly reduced tower crane utilization ratio and efficiency of construction.

In order to solve the problems of the traditional spandrel girder lifting method, an auxiliary lifting device is arranged on a tower crane turntable in the prior art, the spandrel girder lifting in each direction is realized through the rotation of the tower crane turntable, but the cooperation of the tower crane turntable is needed when the spandrel girder is lifted, so that the normal lifting work of a tower crane cannot be carried out during the lifting, and the utilization rate of the tower crane is influenced; and the carousel structure of tower crane is complicated and lower part bearing structure is more, and auxiliary hoisting device can only use single armed formula structure and mounted position comparatively to limit, in order to guarantee the intensity of single armed formula structure, must cause the connection structure weight great with the tower crane carousel, influences the security of tower crane. In addition, because the auxiliary lifting device adopts a single-arm structure and is positioned on the tower crane turntable, the auxiliary lifting device is far away from the bearing beam which needs to be lifted at the lower part, and is lifted by a single point, the bearing beam is difficult to accurately position and inhibit swinging, and the construction efficiency of the bearing beam is seriously influenced. Therefore, it is very necessary to develop a convenient internal climbing tower crane spandrel girder lifting device which has no collision risk, small high falling risk, high lifting efficiency, convenient operation and cyclic utilization.
