Problems solved by technology

Although this combined tower crane foundation has the above advantages, it still has the following disadvantages: First, due to its large volume and heavy weight, it brings great inconvenience to transportation, hoisting and on-site construction, especially on-site construction. When there are underground pipelines or obstacles on the ground, using the foundation will

Embodiment Construction

[0021] Such as figure 1 As shown, the combination of the present invention is composed of a central piece 1, an end piece 2, and a torsion-resistant counterweight 3. The cross-sections of the central piece 1 and the end-piece 2 are I-shaped, and the cross-section of the torsion-resistant counterweight is rectangular. In this embodiment, the material of the assembly is selected as a steel structure.

[0022] Such as figure 1 , figure 2 As shown, take I-shaped steel to make center piece 1 and end piece 2; as image 3 , Figure 4 As shown, the bottom of the I-shaped steel is welded with a torsion-resistant counterweight base plate 25, which is 10 times wider than the width of the upper wing plate of the I-shaped steel, so as to improve the anti-tipping ability of the foundation; figure 2 As shown, the opposite end of the end piece 2 and the joint end of the central piece 1 is sloped, and the included angle of the slope is 30 degrees, so as to reduce the resistance to propul...

Abstract

A tower machine base of metal plastic structure and hydraulic-feed mechanism is provided. The tower machine base contains combination and its connecting device, anchor bolt slot. The combination is made of center part, end part, torsional counterweight part and Cross section of center part and end part are I-shaped and four corners. Cross section of torsional counterweight part is rectangle. The invention can be used wildly.

Description

Technical field: [0001] The invention relates to a fixed combined foundation for construction machinery, in particular to a combined steel and plastic structure tower crane foundation and a special hydraulic propulsion device. Background technique: [0002] In recent years, concrete prefabricated and assembled multi-purpose tower crane foundations are generally accepted because of their short construction period on site, convenient disassembly, assembly and transportation, low environmental pollution, and can improve the utilization efficiency of tower cranes and save the use cost of tower cranes. The industry attaches great importance to it and has been promoted and applied in many regions. Although this combined tower crane foundation has the above advantages, it still has the following disadvantages: First, due to its large volume and heavy weight, it brings great inconvenience to transportation, hoisting and on-site construction, especially on-site construction. When th...
