Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below. However, it should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the scope of the present invention.

Unless otherwise defined, all technical terms and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field of the present invention, and the terms used in the description of the present invention herein are only to describe specific implementations The purpose of the example is not intended to limit the present invention.

Example 1

As shown in Figure 1 and Figure 2, a combined universal foundation, the combined universal foundation is cross-shaped, with high support stability, the combined universal foundation includes a fixed part and a moving part, and the fixed part includes a bolt assembly, The concrete installed on the lower part of the bolt assembly and the installation plate 5 installed on the concrete, the bolt assembly is composed of a number of embedded bolts 1;

The moving part includes a box body 2, a briquetting block assembly 3 and a leg 4 installed on the mounting plate 5, the box body 2 is placed on the mounting plate 5, and the leg 4 is installed on the box body 2, so The pressing block assembly 3 is installed on the upper end of the pre-embedded bolt 1 and compresses the box body 2. In the present invention, a plurality of high-strength bolts are pre-embedded in the concrete, and the box body 2 is used to bear the main load outside the concrete. The embedded bolts 1 are connected with a plurality of briquetting components 3 to compress the box body 2, and the box body 2 passes through the flange. The plate is connected to the outrigger structure, and the outrigger is connected to the tower body. When switching the tower crane to be installed, it is only necessary to move the position of the rigid box, change the installation position of the briquetting block assembly and replace the legs to achieve universal use.

As an improvement of the embodiment, as shown in Fig. 1 and Fig. 2, the embedded bolt 1 is an embedded part, and the lower part of the embedded bolt 1 is embedded in the concrete foundation (concrete), and the relative position cannot be changed. The upper part is exposed, and the exposed length needs to be higher than the total height of the box body 2 and the pressing block assembly 3, so as to facilitate the subsequent installation of nuts to realize the fastening of the box body 2 and the pressing block assembly 3. The actual number of pre-embedded bolts 1 should be more than the actual number used. When moving the position of the box body 2 to change the distance between the legs 4, it is necessary to adjust the connection position or number of the pressure block assembly 3 and the pre-embedded bolts 1, so that Ensure that the pressing block assembly 3 completely presses the box body 2, and the basic common use can be realized.

As an improvement of the embodiment, the upper end of the box body 2 is connected to the outrigger 4 through a flange, the outriggers are easy to assemble and disassemble, and the efficiency of switching and installing the tower crane is high.

As an improvement of the embodiment, as shown in FIG. 1 , four groups of embedded bolts 1 are provided, and each group of embedded bolts 1 is provided with a box body 2 and several pressing block assemblies 3 . Specifically, each group of pre-embedded bolts 1 includes two rows of bolts, and the two rows of bolts are symmetrically arranged on both sides of the box body 2, and a briquetting block assembly 3 is connected between the two opposite bolts, and multiple briquetting blocks are secured by tightening the nuts. The component 3 can compress the box body 2, and for different types of tower cranes, the number of the pressing block components 3 can be adjusted to meet the strength requirements.

As a further improvement of the embodiment, the briquetting block assembly 3 includes a rectangular briquetting block and a gasket. The square briquetting block is installed on the embedded bolt 1 through a nut and a gasket, which is convenient for changing the installation position of the briquetting block assembly. The bottom of the briquetting block is pressed tightly. At both ends of the box body 2, the connection is more stable.

As an improvement of the embodiment, several mounting holes are opened at both ends of the mounting plate 5 , and the embedded bolts 1 pass through the mounting holes on the mounting plate 5 to ensure the level and stability of the mounting plate 5 .

In addition, a method for installing the combined universal foundation includes the following steps: pre-embed bolts in the concrete, and then install a mounting plate 5 on the pre-embedded bolts 1, place the box body 2 on the mounting plate 5 and use a pressing block The component 3 is fastened and connected to the tower body through the legs 4 on the box body 2;

When it is necessary to switch and install the tower crane, it is enough to move the box body 2, change the installation position of the briquetting block assembly 3 and replace the support leg 4.

In specific use, as shown in Figure 3, when the foundation is replaced with different outriggers to connect different types of tower cranes, the reason for changing from Figure 3(a) to Figure 3(b) is that L1 and L2 are different, that is, the tower crane installed The distance between the centerlines of the main chords of the tower body is different. If the position of the embedded bolt 1 does not change, the pressing block assembly 3 pressed on the box body 2 needs to be removed first, and the placement position of the box body 2 should be adjusted (reducing the position of the box body 2). space between), re-press the pressing block assembly 3, and ensure that the pressing block assembly 3 can be completely pressed on the box body 2, and it can be found that the embedded bolt 1 used at this time (that is, connected with the pressing block assembly 3) and the adjustment There are differences in the pre-embedded bolts 1 used before.

The combined universal foundation of the present invention can be used universally by only moving the position of the rigid box, changing the installation position of the briquetting block assembly and replacing the outriggers when switching the tower cranes to be installed, so that tower cranes with large tonnage differences can be used together A set of foundations reduces the waste of resources and costs, and realizes the rational use of materials.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention. Any modification, equivalent replacement or improvement made within the spirit and principles of the present invention shall be included in the protection of the present invention. within range.
