Embodiment 1

[0066] A cylinder frame supported steel platform and a tower crane integral jacking device, comprising a cylinder frame supported steel platform, a tower crane and a jacking power system; the steel platform comprises a steel platform top beam 1, a cylinder frame support 2, an integral jacking up Beam 6, integral jacking lower beam 7 and tower crane support beam 8; cylinder frame support 2 includes cylinder frame support column 201 and reaction beam 202, the reaction beam is preferably an oil cylinder reaction beam; the steel platform top beam 1, oil cylinder The reaction force beam 202, the overall jacking upper beam 6, the overall jacking lower beam 7 and the tower crane support beam 8 are arranged in sequence from top to bottom; the steel platform top beam and the reaction force beam are provided with horizontal limit guide wheels 12, so The guide wheel can selectively resist the tower crane; the bottom of the tower crane is fixedly connected with the tower crane support beam...

Embodiment 2

[0084] like figure 2 As shown in the figure, this embodiment provides a synchronous jacking device. The difference from Embodiment 1 is that in this embodiment, the lower beam for integral jacking and the tower crane are connected, and the upper beam for integral jacking is provided with a horizontal limiter. The guide wheel is positioned to selectively abut the tower crane. The jacking process of the synchronous jacking device is as follows: Figure 17-20 , Figure 17 is the initial state, at this time it is the state of preparation for jacking; Figure 18 The cylinder is in the jacking state. At this time, the hydraulic cylinder drives the cylinder reaction beam to lift, and the cylinder reaction beam drives the steel platform and the tower crane to lift; Figure 19 The cylinder is in the state of lifting back, at this time the hydraulic cylinder drives the overall lifting of the upper beam to lift; Figure 20 It is in the state of completion of lifting.

[0085] The h...

Embodiment 3

[0089] like Figure 13-16 As shown, this embodiment provides an asynchronous jacking method using the above-mentioned integral jacking device, and the method can be decomposed into an initial state, the oil cylinder is lifted, the oil cylinder is lifted back, and the jacking is completed.

[0090] The asynchronous jacking method specifically includes the following steps:

[0091] Step 1: Initial state, complete the preparations before jacking;

[0092] Step 2: In the jacking state, the overall jacking beam bears the vertical load, the jacking power system provides power, and the reaction beam drives the steel platform to jack up in place;

[0093] Step 3: In the lifting state, the jacking power system provides power to drive the overall jacking of the lower beam and the tower ceiling to lift into place;

[0094] Step 4: The jacking is completed.

[0095] Preferably, the step 1 includes: checking whether each component has the lifting conditions, ensuring that the hydraulic ...

Abstract

The invention relates to a barrel frame support type steel platform and tower crane integral jacking device and a jacking method thereof. The integral jacking device comprises a barrel frame support type steel platform, a tower crane and a jacking power system, wherein the steel platform comprises a steel platform top beam, a barrel frame support, an integral jacking upper beam, an integral jacking lower beam and a tower crane supporting beam; the barrel frame support comprises barrel frame supporting columns and a counter force beam, and the steel platform top beam, the counter force beam, the integral jacking upper beam, the integral jacking lower beam and the tower crane supporting beam are sequentially arranged from top to bottom; the steel platform top beam and the counter force beamare provided with horizontal limiting guide wheels capable of selectively abutting against the tower crane; the bottom of the tower crane is fixedly connected with the tower crane supporting beam, oneof the integral jacking upper beam and the integral jacking lower beam is connected with the tower crane, and the other one of the integral jacking upper beam and the integral jacking lower beam is provided with horizontal limiting guide wheels so as to selectively abut against the tower crane; and the jacking power system is used for providing jacking power to enable the steel platform and the tower crane to move. According to the arrangement, integral jacking of the tower crane and the steel platform is realized, and the problem that the tower crane and the steel platform are prone to haveconflicts in the traditional construction process is solved.

Description

technical field [0001] The invention belongs to the technical field of building construction, and particularly relates to an integral jacking device of a steel platform supported by a cylinder frame and a tower crane and an implementation method thereof. Background technique [0002] In the process of super high-rise building construction, tower cranes responsible for vertical transportation such as large tower cranes and integrated platforms such as steel platforms for core tube construction belong to two different equipment systems. The cycle is lengthy, and during the construction process, conflicts are more likely to occur between the tower crane and the steel platform, which leads to the need to stop the construction of the jacking equipment at the site, which affects the construction progress and greatly increases the difficulty of site management. [0003] How to coordinate the work between the steel platform and the tower crane, reduce or avoid conflicts between the ...
